Description

The present invention relates in a first aspect to a set of parts for separating metal-containing particles from moving, in particular schüft- and / or flowable, Fördergut, Furthermore, the present invention relates to the use of the kit of parts according to the invention for the separation of metal-containing particles from moving, in particular scanned and / or flowable conveyed.

In the plastics processing industry devices for the separation of metal parts are known, which are used in a delivery line, in the pourable and / or flowable plastic, for example, from a plastic warehouse in an intermediate storage on a plastic processing machine or directly promoted in this. A separation of metallic impurities from corresponding flow rates is often required because it can come in the presence of corresponding impurities to a hot runner blockage. The known devices have two spatially separate components, which are inserted at a distance one behind the other in the delivery line. These are on the one hand a non-contact metal separator and on the other hand an actuatable by an actuator switch for discharging provided with metal-containing particles conveyed.

The metal separator essentially consists of an induction coil which surrounds the delivery pipe. The metal parts entrained in the conveying current change the inductance of the induction coil, which leads to an output signal which can be evaluated at the induction coil.

With this output of the metal separator, the actuator is controlled. The actuator is generally with a passage having Switch connected, which is actuated by the actuator and deflects the flow into one of two secondary channels, the one channel is connected to the plastic processing machine in conjunction (Gutkanal) and the other channel is z. B. with a collecting container in connection (bad channel), in which the schüft- and / or flowable, metal-containing parts having plastic passes.

From the DE 31 50 503 A a device for separating metal parts from a flow of pourable and / or flowable plastic is known in which the switch is a piece of pipe which is sealed at its upper end, pivotally mounted at the end of the conveyor tube and sealed at its lower end in one Positive locking is performed.

The upper end of the switch is mounted in the manner of a ball joint bearing and the lower end has a sliding shoe, which is guided in a substantially T-shaped in cross-section guide. Due to the pivot radius of the switch, the T-shaped guide and the shoe has a corresponding curve.

The actuator pivots the switch between the two channels back and forth. Since the flow during the Verschwenkvorganges the switch from one to another channel does not tear, also schüft- and / or flowable plastic passes on the T-shaped guide.

In order to ensure that the metal part (s) detected by the metal separator in the flow does not get into the channel leading to the plastic processing machine, it must be ensured that the switch is positioned fast enough over the other channel. For this purpose, a smooth running between the shoe and the T-shaped guide is necessary. This is however in the from the DE 31 50 503 A known device is not ensured because the pourable and / or flowable plastic passes into existing between the shoe and the T-shaped guide spaces and there inhibits the reciprocating motion of the switch or even leads by clamping to a standstill of the switch,

In addition to the clamping of the switch at its lower end, it can also lead to a clamping of the switch at its upper end, This happens in that the plastic at its exit from the conveyor tube on the ball socket of the upper Ball joint bearing impinges. When pivoting the switch, to which the ball socket is attached, namely the plastic can penetrate between the ball socket and the delivery tube, namely

From the DE 24 56 680 A a device for the separation of metal parts from a flow of pourable and / or flowable plastic is known, in which, in contrast to the device described above, the separator surrounds the switch and together with this by an actuator between two continuing channels back and forth , In the starting position of the switch, the passage opening in the flow, so that the emerging from the delivery pipe particle flow passes through the switch in a secondary channel, which leads into a plastic processing machine, If the metal separator determines that in the flow metal parts are included, the With the displacement of the switch, the flow in the conveyor tube is blocked until the switch is emptied of the plastic with the metal part and returned to the starting position.

A disadvantage of this device is that it must be ensured that no plastic from the flow between the delivery pipe outlet and the passage opening of the switch can penetrate into the interior of a housing, Therefore, it is necessary, one above and below the switch the interior of the Provide housing closing seal. The DE 24 56 680 A also proposes seals with additional sealing lips or ribs to seal the interior of the housing against dust and moisture.

This embodiment of the device is unsatisfactory since it causes wear and tear on the seal and the seals in contact with each other and the seals. This has the consequence that the life of the device is short or an increased maintenance required,

The DE 31 50 503 A describes a metal separator for plastic granules, which is arranged in front of a plastic granulate processing machine, the metal separator has a conveyor tube, a ball and a piece of pipe, these components may each be made of non-metallic materials, such as a transparent plastic material or polyamide. Through this structure a ball pivot bearing is provided, through which the conveyed material can be guided into two different openings in order to separate the flow stream or the fluid conveyed thereby. A disadvantage of this device according to DE 31 50 503 A is that the conveying tube and the ball pivot bearing are composed of a variety of items and thus are susceptible to interference due to the entire course of movement of the static conveyor tube and the movable ball pivot bearing. In addition, a cleaning in particular of the transition between the conveyor tube and ball pivot bearing is difficult, since dead volumes can form in the transition between the conveyor tube and ball pivot bearing, in which parts of the conveyed material can deposit. In particular, in the case of a batch change therefore an intensive cleaning of the device is required beforehand.

In the US 3,655,039 a conveying pipe is described, which consists of a tube made of metal or of a synthetic material. This conveyor tube is pivotable and can swing back and forth between two different positions. The position of the conveying pipe is controlled by a metal separator, so that in the case where a metal is detected in the material flow to be processed, the conveying pipe is guided to a first position and in the case where no metal is detected in the conveyed material is, the delivery pipe is guided to a second position. A disadvantage of this device for the separation of metal-containing particles from Fördergutströmen is that the lower end of the conveying pipe is open, so that in particular in non-free falling and not free-flowing goods a separation is difficult. In addition, it may come after leaving the conveyor pipe to a contamination of the conveyed Furthermore, it should be emphasized that the device according to US 3,655,039 not suitable for the separation of Fördergutströmen, which are then not processed continuously, since the device does not provide measures for interrupting the Fördergutstroms, In addition, the device according to US 3,655,039 no through-going through the metal separator integrally formed delivery hose. This makes it necessary to realize a plurality of connections in the region of the metal separator, which in turn are susceptible to interference due to the mobility of the delivery hose. Finally, the construction in the region of the metal separator in the production of a corresponding device is costly.

The EP 0 143 231 A also relates to an apparatus for rejecting metal particles from a product stream. In this apparatus, a delivery line is used which has one to several turns and is formed from a resilient antistatic plastic tube. The conveyor tube itself is not moved, but it ends in a sorting diverter, in which there is a flap through which the diversion of the fluid flow is accomplished,

The reason why in the EP 0 143 231 A A flexible, but at the same time fixed hose is used, is to be seen in the fact that the distance over which the conveyed material between the metal separator and switch is promoted to be extended, so that the switch has a longer time available, between two positions hin- and switch. The delivery line itself is fixed by clamps and not movable,

A disadvantage of this device according to EP 0 143 231 A is in particular the very complicated structure of the feed switch and the associated failure-prone forming the lower portion of the device.

In addition, other devices for separating metal-containing particles from fluid streams are known from the prior art, These usually use drum systems, in which it comes by switching from two states to a different outlet of the material, these drums usually have the disadvantage that they have a very large dead volume in which residual particles can deposit. In the case of a production change on the apparatus, contamination of the material with old residues from the dead volumes of the drum may occur, which is likewise disadvantageous. A magnetic separator having the features from the preamble of claim 1 from the document is also known to the person skilled in the art US 3 402 820 A known.

In addition, funnel magnets are known to those skilled, which consist of a large number of small bar magnets and are assembled into a lattice structure, Their use, for example, at the hopper of a delivery line, leads to a variety of disadvantages, such as a cross-sectional taper in the delivery line, a short fishing distance for Magnetic foreign particles and a high chance of passing FE metal particles, Also, only two pole sides of the lattice magnets have a large catching force, which is not sufficient due to the commonly selected ferrite magnets,

Another drawback that occurs with the foregoing metal separator devices is that they are not capable of redirecting a standing column of the delivery stream. If there is a standstill in the arranged after the metal separator for further processing of the conveyed material, the conveyed can not leave the metal separator and remains in the delivery pipe. When the product column formed thereby presses on the separator, clogging of the separator generally occurs, which in turn requires manual intervention and cleaning of corresponding portions of the metal separator.

The object of the prior art is to develop a kit of parts with which metallic particles can be removed from a conveyed material, whereby a higher magnetic range of action in the direction of the conveyed material is achieved and a higher speed of the conveyed material is made possible.

This object is achieved by a device according to claim 1 of the present invention and by the use according to claim 3. Preferred embodiments of the present invention are subject of the subclaims,

1. a) eine Förderleitung 2 aus einem nicht-metallischen flexiblen Material, wobei die Förderleitung 2 einen Einlass 3 und einen Auslass 4 aufweist,
2. b) eine formschlüssig mit dem Auslass 4 der Förderleitung 2 verbundenen Führung 5, welche mindestens zwei Öffnungen 6, 7 aufweist,

For a better understanding of the invention will
initially presented a device 1 for the separation of metal-containing particles from pourable and / or flowable conveyed, comprising

1. a) a delivery line 2 made of a non-metallic flexible material, wherein the delivery line 2 has an inlet 3 and an outlet 4,
2. b) a guide 5 which is connected in a form-fitting manner to the outlet 4 of the conveyor line 2 and which has at least two openings 6, 7,

The device 1 is designed such that the outlet 4 of the delivery line 2 in at least two different Positions 6 'and 7' can be performed, wherein the at least two positions 6 'and 7' correspond to the at least two openings 6 and 7 of the guide 5,

Because the device 1 has a delivery line 2, which can be guided in different positions on the guide 5 due to its flexibility, a complex discharge element, with which at least two different waste channels are controlled, is not required. Separation of the product flow is effected by simple displacement of the outlet 4 of the flexible conveyor line. 2

1. 1. kein Material des schütt- und/oder fließfähigen Förderguts an der Übergangsstelle zwischen Förderleitung 2 und Führung 5 austreten kann und/oder
2. 2. ein Verschieben des Auslasses 4 der Förderleitung 2 auf der Führung 5 möglich ist.

The delivery line 2, through which the scrapery and / or flowable conveyed material flows, is positively connected to the guide 5, It is understood by the term that the delivery line 2 is positively connected to the guide 5, that the delivery line 2 on the guide 5 is arranged so that

1. 1. no material of the pourable and / or flowable conveyed at the transition point between the delivery line 2 and 5 guide can escape and / or
2. 2. a displacement of the outlet 4 of the delivery line 2 on the guide 5 is possible.

A significant advantage of the device 1 is the high flexibility of the delivery line 2, which is preferably made of a non-metallic flexible material. Since the delivery line 2 is designed to be flexible, it is possible that the delivery line 2 is formed in one piece and can be dispensed with a separate switch or divider, The separating device itself is an integral part of the delivery line 2 and the flow 11, which extends through the delivery line 2 moves, does not have to go through for separation a special separating device,

The device 1 also has a metal separator 8. This metal separator 8 is used to detect metal-containing particles in the pourable and / or flowable material 11 and is usually located outside the feed line 2, for example, arranged radially around the feed line 2 radially, the metal separator 8 thus enables a contactless scanning of the flowing through the feed line 2 pourable and / or flowable conveyed material 11 with respect to metal particles contained therein. With regard to the exact configuration of the metal separator 8, reference is made to the extensive prior art, which is known per se to the person skilled in the art. In principle, any metal separator 8 is suitable, which is designed such that it can be arranged outside the delivery line 2, for example radially around the delivery line 2, and can detect metal-containing particles in the delivery stream 11.

As already mentioned, the delivery line 2 is preferably formed in one piece. It is understood by a one-piece conveying line 2, a delivery line, which is formed continuously in one piece, starting above the metal separator 8 with the inlet 3 to the outlet 4 of the delivery line 2, which is flush on the guide 5. It follows that in particular it is provided that the delivery line 2 is guided through the metal separator 8 and in the region of the metal separator 8 it is not intended to assemble the delivery line 2 from two or more individual parts. Moreover, within the scope of the device 1, it is also preferably not provided that the delivery flow 11 is guided in the region of the metal separator 8 through a hard paper or a plastic tube.

Due to these features, the construction of the device 1 compared to the prior art is significantly simplified and cost-effective production of appropriate devices is possible, Due to the one-piece design of the delivery line 2 is omitted transitions between individual areas of the delivery line 2, which are both susceptible to interference and on the other lead to possible dead volumes, which generally require special reining, especially when changing batches,

The device 1 may have a delivery line 2 which has a constant diameter. In addition, however, a conical inlet of the delivery line 2 in the direction of the outlet 4 of the delivery line 2 is possible,
Usually, the diameter of the delivery line (2) is 10 to 350 mm, preferably 10 to 200 mm, more preferably 10 to 100 mm. In addition, however, other diameters are conceivable; the choice of the exact diameter of the delivery line 2 Depends on the particular conditions of the devices, which are used in combination with the device 1, as well as on the nature and characteristics of the conveyed 11 from.

The device 1 has a guide 5, in which at least two openings 6, 7 are provided on. Moreover, it is also conceivable that the device 1 has a guide 5 with a plurality of openings, for example 3, 4, 5, 6 or 7 openings, as in FIG FIG. 3 outlined. A plurality of openings in the guide 5 plays a role in particular if not only metal-containing particles from a moving, in particular schüft- and / or flowable, 11 are to be separated, but the moving, in particular schüft- and flowable, conveyed itself after different properties should be separated. The openings are controlled in this case depending on the respective properties of the conveyed material. Optionally, this or other detectors are required in this embodiment,

As a rule, at least one of the openings 6 and / or 7 is adjoined by a further device 9, with which the moving, in particular scannable and / or flowable material 11, which has been freed of metal-containing particles, is further processed. These further devices may be, for example, a press and / or injection molding machine. Further possible devices 9 are filling plants, drying plants and dedusting plants.

The exact configuration of the transfer line 16, which adjoins the opening 6 or 7 of the device 1 and the purified and freed from metal particles and particles flow to the other device 9 may be arbitrary and depends essentially on the mechanical specifications of the other device 9 off. For example, the further device 9 can be connected to the opening 6 or 7 of the guide 5 of the device 1 via an adapter 10, such as a flange connection.

For separating the metal-containing particles from the moving, in particular pourable and / or flowable conveyable material 11, the device 1 behind the metal separator 8 in the flow direction on an adjusting device 12, which is formed is that it shifts the outlet 4 of the flexible delivery line 2 on the guide 5,

It is provided in particular that the delivery line 2 is provided with the adjusting device 12 so that the outlet 4 of the delivery line 2 can be guided into at least two different positions 6 'and 7' of the guide 5, wherein the different positions 6 'and 7' the openings 6 and 7 of the guide 5 correspond.

As a result, the delivery line 2 is placed so that the Fördergutstrom either through the opening 6 or through the opening 7 leaves the device 1 again.

1. a. wenn der Metallabscheider 8 ein metallhaltiges Teilchen in dem bewegten, insbesondere schütt- und/oder fließfähigem Fördergut 11 detektiert, die Förderleitung 2 durch die Stelleinrichtung 12 so geführt wird, dass der Auslass 4 der Förderleitung 2 auf der Führung 5 so positioniert wird, dass das bewegte, insbesondere schütt- und/oder fließfähige Fördergut 11 durch die erste Öffnung 6 der Führung 5 die Vorrichtung 1 verlassen kann; und
2. b. wenn der Metallabscheider 8 kein metallhaltiges Teilchen in dem bewegten schüft- und/oder fließfähigem Fördergut 11 detektiert, die Förderleitung 2 durch die Stelleinrichtung 12 so geführt wird, dass der Auslass 4 der Förderleitung 2 auf der Führung 5 so positioniert wird, dass das bewegte, insbesondere schütt- und/oder fließfähige Fördergut 11 durch die zweiten Öffnung 7 die Vorrichtung 1 verlassen kann,

The adjusting device 12 for positioning the outlet 4 of the delivery line 2 is controlled in response to the signals of the metal separator 8 so that

1. a. when the metal separator 8 detects a metal-containing particle in the moving, in particular pourable and / or flowable material 11, the conveying line 2 is guided by the adjusting device 12 so that the outlet 4 of the conveying line 2 is positioned on the guide 5 so that moved, in particular pourable and / or flowable conveyed 11 through the first opening 6 of the guide 5 can leave the device 1; and
2. b. when the metal separator 8 detects no metal-containing particles in the moving scannable and / or flowable conveyed material 11, the delivery line 2 is guided by the adjusting device 12 such that the outlet 4 of the delivery line 2 is positioned on the guide 5 so that the moving, in particular pourable and / or flowable material 11 can leave the device 1 through the second opening 7,

Hereby, a separation of metal-containing particles after detection by means of the metal separator 8 by a different positioning of the outlet 4 of the conveying line 2 on the openings of the guide 5 is possible. In the present case, the opening 6 is referred to as that opening through which the Fördergutstrom provided with metal-containing particles leaves the device 1, and the opening 7 is referred to as the opening through which the Fördergutstrom freed from metal-containing particles leaves the device 1.

The adjusting device 12 can be operated as desired. In question, for example, comes a pneumatic or hydraulic cylinder, under the action of the delivery line 2 is guided in the different positions 6 or 7 on the guide 5. Alternatively, the outlet 4 of the delivery line 2 can also be moved by means of an electric lifting and / or actuating magnet into the different positions 6 and 7 on the guide 5.

In order for the metal-containing particles and particles to exit from the moving, in particular pourable and / or flowable conveyed material 11 as possible, the metal separator 8 is preferably positioned on the conveying line 2 such that the greatest possible distance between the metal separator 8 and the outlet 4 the delivery line 2 is given. As a result, after the metal separator 8 has detected a metal-containing particle in the moving, in particular pourable and / or flowable conveyed material 11, a sufficient period of time in which the adjusting device 12 acts on the conveying line 2 and the outlet 4 of the conveying line 2 in the respective correct position 6 or 7 can lead.

In a further embodiment of the device 1, it is possible, as already mentioned, for not only two openings but several openings, in particular three, four, five, six or seven openings, to be provided in the guide 5 the guide 5 are provided, it may be advantageous to arrange the respective openings on the guide 5 in a radial arrangement about the longitudinal axis 13 of the conveying line 2 on the guide 5. In this case, the conveying line 2 can then be controlled by the adjusting device 12 about its own longitudinal axis 13 in a rotating movement by, for example, a total of 360 degrees on the guide 5 ( FIG. 3 ). A corresponding arrangement of the delivery line 2 is in the FIG. 2 shown.

In a further embodiment, instead of the conveying line 2, the guide 5 can move radially through 360 ° to the opening of the conveying line 2, so that the different openings of the guide are positioned under the opening of the conveying line 2. In this case, the positioning of the openings of the guide 5 would be through the metal separator 8 triggered and controlled by a further device accordingly. In this case, an adjusting device for controlling the delivery line 2 would not be necessary, since this remains at a position.

In a further embodiment, both the guide 5 and the conveyor line 2, which allows a particularly fast reaction time and thus a particularly rapid separation of the separating parts, a corresponding operation is of course not only with the in FIG. 3 illustrated embodiment, but also with in the FIGS. 1 and 2 illustrated embodiment possible.

In the case of a radial arrangement of openings on the guide 5 about the longitudinal axis 13 of the conveying line 2, the guide 5 is preferably formed in the form of a substantially flat bottom plate 17 with a corresponding number of openings. The adjusting device 12 is designed such that it can guide the outlet 4 of the delivery line 2-preferably in accordance with signals of the metal separator 8-onto the different openings of the guide 5.

In a further embodiment, however, the guide 5 can also be formed in the shape of a curved bottom plate 18, as in the present FIG. 1 is shown. Also in this case, the adjusting device 12 performs the outlet 4 of the delivery line 2 in different positions, which correspond to the openings of the guide 5.

So that a sufficient flexibility of the delivery line 2 is given and the adjusting device 12 can lead the outlet of 4 of the conveyor in the corresponding positions of the openings of the guide 5, the delivery line 2 is preferably made of a non-electrically conductive flexible material, in particular a non-electrically conductive flexible Plastic material formed. In this case, the delivery line 2 may be formed as a hose or a pipe. As a material for the delivery line 2 is a plastic material, for example in the formula of a rubber hose or a plastic film, or a textile material in question.

The device 1 for separating metal-containing particles from schüft- and / or flowable conveyed material 11 is preferably, as already mentioned, used in combination with other devices 9, with which the conveyed 11th is processed further. Usually, therefore, the device 1 is spatially above the other device 9, with which the further processing of the conveyed material 11 takes place. This also results in the problem that a compact design of the device 1 may be required due to the limited space available in industrial plants. This results in connection with the use of such machines, in particular injection molding machines, special spatial-constructive problems, since the metal separator must namely be arranged above the machine inlet funnel of the injection molding machine, which falls into the well-considered Fördergutstrom. The metal separator itself has its own inlet funnel on its upper side. It thus comes to an extremely large height, which makes it problematic to accommodate the factory existing feeders with the feed pipes and the usually existing mixing unit also above the machine, the high structure above the inlet funnel of the other device 9 can also be a complex, bulky, additional Framework construction to keep the metal separator 1 above the machine-side funnel required. On the other hand, the scaffolding makes it difficult to access the machine,

On the other hand, the height of the structure of the device 1 is determined by the required length of the delivery line 2. The delivery line 2 must be so long that, after the detection of the metal-containing particle in the moving, in particular scannable and / or flowable conveyed material 11 by the metal separator 8, a sufficient time is available for the adjusting device 12, the outlet 4 of the delivery line 2 to place the corresponding opening in the guide 5. However, the required length of the conveying line 2 also depends on the moving, in particular pourable and / or flowable conveyed material 11 and the speed at which the moving, in particular scannable and / or flowable conveyed material 11 flows through the device 1.

There is therefore a particular need to provide metal separators for moving, in particular scannable and / or flowable material to be conveyed, which if possible has a small structure. Such an arrangement is due to the flexible design of the invention provided delivery line 2 and the absence of mechanically complex units for the separation of the flow rate, such as switches, possible. Due to the flexible design of the delivery line 2, it is possible to extend the distance length of the delivery line 2 between the metal separator 8 and 4 outlet by installing turns, This can increase the Durchfiusszeit of the conveyed 11 without providing a large distance between the metal separator 8 and outlet 4, so that a sufficient reaction time for switching between two openings is given.

Subsequent to the opening through which the conveyed material contaminated with the metal-containing particles is discharged from the device 1, there may be, for example, a collecting container. The moving material, in particular pourable and / or flowable conveyed material, which is contaminated with metal-containing particles and arrives in this collecting container can optionally be subjected to a recycling process, this can reduce the amount of waste material of the transported material,

In a further embodiment, the device 1 further comprises a device 14 with magnets 34, which is suitable for the deposition of ferromagnetic metal particles and other sufficiently magnetic particles from the moving, in particular scannable and / or flowable conveyed material 11. The device 14 is preferably designed so that magnetic particles with sizes of more than 0.1 μm can be detected.

In one embodiment of the present invention, the device 14 becomes alone, ie, without the previously described device 1 according to FIGS FIGS. 1 to 3 , used.

The following description of the device 14 relates to both embodiments with and without the previously described device 1.

The device 14 is adapted to remove ferromagnetic particles and other sufficiently magnetic particles from a flow 11. The apparatus 14 may be combined with a downstream metal separator according to the apparatus 1 described above or another sensor and separation technique or used alone on an already existing conveyor line 2 in the prior art,

The device 14 can be arranged radially around a delivery line 2, as in the FIGS. 6 to 8 is shown. Thus, the device 14 is preferably outside the feed line. 2

In this case, it is particularly preferred if the device 14 is constructed from a plurality of individual magnetic rods 34, which extend in the tube adapter made of stainless steel 20 parallel to the conveying direction of the conveying line 2. In this way, a sufficiently long fishing distance is generated, A corresponding arrangement of the magnetic bars in one embodiment of the pipe clamp magnet 23 is in FIG. 11 shown.

Such a device 14, in particular a pipe clamp magnet 23, can be used directly around an already existing metallic or non-metallic conveyor line 2 from the prior art. Alternatively, such a device 14 can be used in combination with a pipe adapter made of stainless steel 20 to an already existing feed line 2 or a feed line 2 according to the invention.

In the interior of the tube adapter made of stainless steel 20, which is installed via the couplings 21a and 21b in any conveyor line 2, one or more deflecting elements 19, preferably at least two deflecting elements 19 may be provided. The deflection lead to a turbulence and / or deflection of the pourable and flowable conveyed 11 lead, whereby the residence time of the particles of the flow 11 in the region of the collecting recess 24 of the tube adapter made of stainless steel 20 is increased. Furthermore, the distance between the magnetic conveyed material and the magnet 34 of the device 14 can be reduced by the deflection of the particles in the direction of the inner wall of the delivery line 2. Finally, an increase in the effective range of the magnet 34 is achieved by one or more deflection elements 19. Possible embodiments of the deflecting elements 19 comprise a shape selected from the group comprising pointed, spherical or rounded elevations, wings, noses, sorting points and bars, wherein the surfaces and / or edges of the deflecting elements 19 projecting into the conveying line 2 can be variably shaped, in particular concave, convex or combinations of concave and convex,

A particular embodiment of these deflecting elements 19 is in FIGS. 12a and 12b represented, in which the deflecting elements 19 are realized by two mutually perpendicularly arranged rods 19. FIG. 12 shows the cross section of the tube adapter of stainless steel 20 with a top view of the superimposed bars. The bars may optionally provide an in-plane cross, or two separate bars may be positioned within the containment well 24 at an arbitrary distance from one another. The position of each rod and the angle of the rods to each other are arbitrary, preferably to be chosen so that an optimal turbulence and / or deflection of the conveyed material 11 is achieved to the outside.

In another embodiment, the stainless steel tube adapter 20 is combined with a sensor, such as an inductive proximity switch or a gravimetric sensor, for example, in the well cavity 24, which provides a pulse with a sufficient amount of trapped material. In this case, the stainless steel tube adapter 20 can be freed from the accumulated material. This can be done for example by removing the tube adapter made of stainless steel 20 from a feed line 2 and manually removing the accumulated material from the tube adapter 20. Further, the pulse can trigger a reversal of the magnetic field, whereby the accumulation of material from the collecting well 24 is released and carried away by the shearing force of the conveyed, The same pulse, which controls the polarity reversal, also controls the tube adapter made of stainless steel 20 downstream two-way Soft the magnetic accumulation then deposits. This can for example by in the FIGS. 1 to 3 be realized device described

The sole use of the device 14 with magnets 34 with or without the tube adapter made of stainless steel 20 is particularly advised and recommended where no metal separator can be retrofitted or desired. The present invention consequently also encompasses the independent use of the device 14 according to the invention, the use of the device 1 according to the invention and the combination of the device 14 with the device 1.

The advantage of the combination is that the accumulation of magnetic microparticles in the downstream metal separator 8 produced by the device 14 with the magnet 34 now triggers and detects a metal alarm when it is discharged, which allows the accumulation of this accumulation by the device 1. The combination reduces metal impurities by initially not detectable micro particles and consequently increases the quality of the conveyed material,

In a particular embodiment of the present invention, this device 14 is designed so that it can be positively arranged, for example in the form of a clamp, around the conveyor line 2 by 360 °. It is provided in particular that the magnet 34 of the device 14 is arranged in front of the metal separator 8 with respect to the conveying direction of the conveyed material flow. As a result of the action of the magnet 34 on the delivery flow 11, ferromagnetic particles accumulate in the region of the magnet 34 within the delivery line 2. These ferromagnetic particles thus do not reach the region of the metal separator 8. This makes it possible to keep the metal separator 8 as free of ferromagnetic particles as possible such that the number of firings of the metal separator 8 is reduced overall and at the same time less scrap material is formed,

In a particular embodiment of the present invention, the magnet 34 comprises neodymium. Other possible magnets are electromagnets. Corresponding neodymium magnets have sufficient strength to accumulate ferromagnetic particles in a delivery line 2 in the region of the magnetic field when the magnet 34 bears radially on the delivery line 2.

In a further embodiment of the present invention, the device 14 is preferably arranged releasably flush with the form of the delivery line 2. A suitable thumbscrew, as in the FIGS. 6 to 8 at position 22 is sufficient to allow attachment and release of the device 14. Locking may also be provided at position 22 to secure access by third parties or unauthorized persons to device 14. The lock may also be mounted in addition to the thumbscrew at an additional position to position 22 adjacent the thumbscrew. As a result, it is possible in individual cases that the device 14 can be removed from the delivery line 2, whereby efficient ways to separate out in the Fördergutstrom accumulated in the region of the magnet 34 ferromagnetic material, without at the same time a large amount of conveyed is removed, more embodiments follow below. Also, the device 14 can be fixed by means of a bayonet lock on the conveyor line 2,

In another embodiment, the device 14 includes a suitable stainless steel tube adapter 20 having a variable diameter, for example, 3 to 8 cm. The tube adapter 20 has a collecting recess 24 within the delivery line 2 in which the attracted by the magnet 14 metal particles and other magnetic particles accumulate, the magnet 14 is fixed from the outside of the tube adapter 20. The collecting recess 24 is flattened obliquely outwards starting from the edge of the tubular adapter 20, and the depth and length of the collecting recess 24 are selected depending on the diameter of the conveying line 2,

In any case, the tube adapter made of stainless steel 20 and the collecting recess 24 of the tube adapter 20 is formed so that the conveyed as close to the magnet is passed over, so that the highest possible attraction rate is achieved by the catching force of the magnet 14. Due to the collecting recess 24, an enlargement of the diameter is achieved, whereby the shear forces change, Therefore, the tube adapter 20 and the collecting recess 24 is selected so that the shear forces acting on the conveyed material are not stronger than the force acting on the particles to be separated attraction of the magnet 14. Thus, despite the shearing forces acting on the conveyed optimum catching force and thus separation is achieved,

In another embodiment, the tube adapter made of stainless steel 20 in the interior of one or more deflecting elements 19, which allow a diversion of the conveyed. This is particularly advantageous in lines with larger diameters, since the catching force of the magnet 14 towards the center of the diameter of the delivery line 2 towards weaker. In order to ensure optimum separation of the particles, the conveyed material is discharged by these deflecting elements 19 to the outside to the conveying line 2, so that the region of the weakest catching force of the magnet 14 is reduced, in particular is / are the deflecting elements 19 at the transition to the collecting recess 24 of the Tube adapter made of stainless steel 20 centrally mounted at an angle of 45 ° to the transverse axis of the conveying line 2, A corresponding arrangement of deflecting elements 19 is for example in FIG. 12 shown.

The position of the tube adapter made of stainless steel 20 in a delivery line 2 can be arbitrary, for example at the suction lance or at the mill outlet,

The pipe adapter 20 may be clamped in a further embodiment by means of couplings 21a and 21b, which are used as pipe connections, in / on any existing line regardless of the material of this line. Also on the clutches 21a and 21b, the use of a locking of the pipe adapter made of stainless steel 20 is conceivable. If the delivery line 2 consists of a flexible material, and if the delivery line 2 can thereby be plugged onto the tube adapter 20, a coupling 21a / 21b may be superfluous.

In a further embodiment, the collecting recess 24 of the tube adapter 20 has an opening which allows the collected particles after removal of the device 14 from the tube adapter 20 without removing the complete tube adapter 20 together with the coupling to remove from the line.

In a further embodiment, the magnet 34 does not act flush with 360 ° on the delivery line 2, but only on a limited area of the delivery line 2. In this embodiment, the magnet 34 is designed so that the magnet 34 is an area with an angle of 300 ° - 270 °, preferably 270 ° - 200 °, particularly preferably 230 ° - covers 180 °. In this case, the trapped particles are only accumulated in this region of the collecting well 24 on which the magnet 34 acts. In a particular embodiment, the limited area of the magnet 34 is at the flap provided in the collecting well 24 for opening the collecting well 24, such as shown in the previous embodiment, positioned. This allows for rapid removal of the particles after removal of the device 14 and opening of the catch well 24 without disassembly of the complete tub wheel spacer from the existing line.

The device 14 can be opened, for example, by a suitable joint and / or member 15 and thus placed in the form of a clamp around the delivery line 2 or be removed from the delivery line 2.

In a further embodiment, the magnet 34 is formed so that it has oppositely directed poles and with the aid of these oppositely directed poles, the device 34 can be fixed in a form-fitting manner in the form of a clamp form-flush to the delivery line 2.

In addition, a closed device 14 can be used in the context of the present invention, which is placed over the delivery line 2, a removal of accumulated ferromagnetsicher particles can then for example take place, that the device 14 is moved opposite to the flow direction of the conveying stream 11 and within the conveying line 2 deflecting elements 19 are in a form selected from the group comprising bumps, wings, lugs, sorting switches or rods, on which the accumulated ferromagnetic material stripped off becomes,

The FIG. 13 shows a preferred embodiment of the present invention provided pipe clamp magnet in a plan view of the magnet in the flow direction of the fluid. In a housing 35 magnets 34 are incorporated alternately, wherein the respective magnets 34 each have only one polarity. The polarity of the arranged in the housing magnets 34 is alternating, which is apparent from the FIG. 13 can be recognized by the designation S and N. Furthermore, the shows FIG. 13 a hinge 15 and handles 36 for opening the hinge 15.

Radially outwardly located at the level of each magnet 34, an iron yoke 26, which extends in the direction of the fluid preferably as far as the magnets 34. This ensures that the magnetic field extends substantially only in the direction of the center of the pipe and thus the Magnetic field in the region of the fluid to be separated is greatest, Furthermore, a magnetization is reduced outside of the clamp magnet,

The two parts of the pipe clamp magnate can be arranged around a delivery line 2 and fixed by a closure, as already stated, to the pipeline. The closure can also be designed as a bayonet closure,

The device 14 is also preferably designed so that the inner surface, i. the surface of the device 14, which adjoins the delivery line 2, has no bulges, for example because of the magnets 34 used therein, so that the device 14 is in a form-fitting manner against the delivery line 2,

The advantage of using the device 14 over the prior art is that it can be used without metal separator alone for the isolation of metal contaminants on any conveyor line 2, of metallic and non-metallic material, in any easily accessible position. In addition, the magnetic field penetrates deep into the delivery line 2 and the Fördergutstrom 11. A special The advantage is that the magnet 34 is mounted from the outside to the delivery line 2 and thereby contact of the magnet 34 is avoided with the conveyed in the flow 11. This is particularly advantageous in such lines in which, for hygienic reasons, for example in the food, food, beverage and pharmaceutical industries, the purity of the product and thus quality plays a major role. Furthermore, the inventive magnet 14 with a suitable tube adapter 20, a cross-sectional tapering and throughput reduction, as occurs in grid magnets avoided. By using the magnet 34 according to the invention with the corresponding tube adapter 20 in a method according to the invention, there is no accumulation of material.

The devices according to the invention are particularly suitable for the separation of metal-containing and / or magnetic particles from moving, in particular pourable and / or flowable Fördergutströmen selected from the group consisting of free-flowing, free-falling, slowly flowing and stationary streams. Furthermore, it can be conveyed streams from the areas of the food and food industry, the chemical industry, in particular the pharmaceutical and agrochemical industry, the plastics processing industry, the beverage industry and the wood pellet industry.

Moreover, the present invention also relates to the use of a magnet according to the above definitions for the deposition of ferromagnetic metal particles in the interior of a delivery line 2, wherein the device 14 is arranged in the form of a clamp outside the delivery line 2 form-fitting. In this general embodiment encompassed by the present invention, it is also possible to dispense with the metal separator 8 described above. This embodiment is thus characterized solely by the use of appropriately trained magnet 34.

The use of the device 1 for separating metal-containing particles from moving, in particular pourable and / or flowable conveyed material preferably takes place in such a way that

1. a. If the metal separator 8 detects a metal-containing particle in the moving, in particular pourable and / or flowable material 11, the conveying line 2 is guided by the adjusting device 12 or the guide 5 is guided to the delivery line 2 so that the outlet 4 of the delivery line. 2 is positioned on the guide 5 so that the pourable and / or flowable conveyed material can leave the device 1 through a first opening 6 of the guide 5; and
2. b.

The use is in particular characterized in that the predetermined period of time in which the outlet 4 of the conveying line 2 is positioned on the guide 5 so that the outlet 4 of the opening 6 corresponds, depending on the length of the conveying line 2 between the metal separator 8 and Outlet 4 and the flow rate of the pourable and / or flowable material 11 is defined,

It follows that the time span after which, after detection of a metal-containing particle, the adjusting device 12 has to drive the outlet 4 of the conveying line 2 into the corresponding position depends on the length of the conveying line 2 between the metal separator 8 and the outlet 4, which Flow rate and the conveyed.

In a further embodiment, it is possible to use a detector other than a metal separator and to separate the flow rate on the basis of other properties, such as density, light diffraction, color, etc. with the device according to the invention. For this purpose, the same features apply as described above for a device in which a metal separator is used,

• d". durch die Vorrichtung 1 - wie zuvor beschrieben über eine Öffnung - ausgeschieden werden.

In addition, the present disclosure is also characterized by a use in which, in the case of the common use of a device 1 in conjunction with a device 14, the deposition of metal-containing and / or magnetic particles from moving, in particular pourable and / or flowable conveyed material 11 is done by that

• a "ferromagnetic particles from the moving, in particular pourable and / or flowable material 11 are bound within the conveying line 2 by means of the magnet 14, which accumulate at the height of the device 14 in the conveying line 2,
• After a predetermined period of operation of the device 1, the device 14 is released from the conveying line 2 such that the ferromagnetic particles enter the device 1 according to the definitions described above or are stripped by moving the magnet 34 via a deflecting element 19 in the conveying line 2 become;
• c "are detected in the device 1 according to the procedure described above by a metal separator 8, and
• d "through the device 1 - as described above via an opening - excreted.

The sole use of a corresponding magnet for the accumulation of ferromagnetic particles in delivery lines has a number of advantages:
By using appropriate magnets can be achieved enormous cost savings through lower material rejection of the metal separator.

The collected magnetic metal reaches after the cleaning cycle of the magnet at the same time the metal separator 8, which leads to concentrated metal firing associated with low material waste when the magnet 34 in combination with a device according to the FIGS. 1 to 3 is used.

A simple cleaning of the magnet 34 without opening the pipe is possible via the downstream metal separator 8 by opening the device 14. By a round, adapted to the conveyor line 2 design, a strong catching force of the magnet 34 can be realized.

Also, an integration of the magnet 34 in existing systems is possible without design effort, in which case the deposition of the ferromagnetic particles by (possibly existing) (Alt -) - metal separator takes place.

By inventively provided magnet 34, a high cleaning effect of the conveyed material can be achieved. Even the very smallest, under normal procedural requirements undetectable ferromagnetic dust particles, generate a metal alarm as accumulation and are now detectable in a downstream Metallabscheider, This makes it possible to detect by the accumulation and very small ferromagnetic particles,

The magnet 34 can also be used without a downstream metal separator. Without a metal separator, the cleaning should be done manually depending on the possibilities according to the system.

The magnets 34 can also be used on non-magnetic stainless steel pipes; In particular, by using the strongest neodymium magnets as permanent magnets or electromagnets with high catch depth, efficient accumulation of ferromagnetic particles is possible.

The use of a magnet 34 provides convenient, retrofittable protection without contact with the product.

Corresponding magnets 34 are wear-free and have a virtually unlimited lifetime, since they are mounted outside of the conveyed product-containing product stream and each delivery line and thus no material contact is present.

A cross-sectional taper of the delivery line and a reduction in throughput - as in grid magnets - does not occur when using the inventively provided magnet.

Corresponding magnets can be used under pressure conditions, suction conditions or in free-falling delivery conditions,

Even highly magnetically contaminated material can be cleaned effectively and cost-effectively,

Due to the low investment requirement, short payback periods can be realized.

Magnets used at the beginning of production make it impossible to distribute magnetic metal contaminants throughout the production line, making removal later more difficult and expensive. The sooner ferromagnetic smallest particles are removed, the less damage they cause.

Process example for cleaning the pipe clamp magnet without metal separator

For cleaning, the existing pipeline is modified directly at the silo outlet insofar that a part of the pipeline on which the magnet 14 is clamped is removable. This is done by replacing a piece of the existing pipe with a removable new piece. The connection can be made via pipe clamps on both pipe ends. To clean the metal accumulation, the line together with closed magnet 34 is removed with the promotion switched off, after removal of the section, the device 14 is opened with the magnet 34, It is recommended to collect the then dissolving metal residues in a container and perform the cleaning so that the metal accumulations do not fall out of line and then inadvertently adhere to the magnet 34. Note that the portion also disengages upon opening of the device 14 of the magnets 34. The catching force of the magnet 34 can attract metals in the opened state. The exact procedure is dependent on the customer-specific conditions, After cleaning, the magnet 34 is placed again in the middle of the section and sealed, Then the replacement into the pipe by pipe clamps, Other solutions for cleaning the pipes are conceivable.

A corresponding method example for cleaning the magnet according to the invention with a conventional, non-inventive metal separator is in the FIG. 4 shown,
