Description

Wet processor for rope-like textile

Technical Field

The invention relates to a wet treatment machine for textile goods in rope form, comprising a closed container and a Venturi nozzle system to which a flow of a transport medium is supplied in order to drive a continuous fabric in rope form circulating in the container in a defined circumferential direction.

Background

Such wet treatment machines, which are known in practice in various embodiments as jet dyeing plants and the like, operate hydraulically or aerodynamically, irrespective of whether the transport medium flow is liquid or gaseous. The continuous fabric rope conveyed by the conveying nozzle system is folded by a folding device when being output from the conveying nozzle system, and then is stored in a storage, and the continuous fabric rope is continuously taken out of the storage and conveyed to a fabric rope inlet of a conveying air injection system. In order to remove the fabric rope from the storage and feed it into the fabric rope inlet of the delivery nozzle system, it is assigned a take-up device, which usually has a winch for each delivery nozzle of the delivery nozzle system. The motor-driven winch is located in the path of the fabric rope in front of the fabric rope inlet assigned to its delivery nozzle and deflects the fabric rope drawn off substantially vertically from the reservoir by at least 90 DEG before it enters the fabric rope inlet of the delivery nozzle. A part of the treatment liquid carried along by the rope falls on a substantially vertical section of the rope run between the winch and the reservoir, which facilitates this dripping, since the rope rests with its weight on the surface of the winch and is therefore pressed more or less together.

In order to spread the treatment liquid as uniformly as possible on the endless rope-shaped fabric, the treatment liquid is circulated by a dye liquor circulating pump and is applied to the rope-shaped fabric by a conveying medium flow. In wet treatment machines of the type known from EP0078022, the treatment agent is added in atomized form to the gas stream, which serves as a transport medium stream for the endless rope-like fabric. In another aerodynamic piece dyeing machine according to EP09455381, the treating agent is fed into the nozzle housing of the delivery nozzle, wherein the treating agent particles are sprayed by the gaseous delivery medium stream uniformly through the nozzle annular gap onto the continuously advancing rope-like textile, in which they are attenuated during the reinforcing path which continues through the delivery nozzle.

In practice, it has been found that the amount of liquid treatment liquid that can be sprayed into a gaseous transport medium flow in an aerodynamically operating ejector wet processor is limited. That is to say, the drops of treatment liquid introduced into the transport medium flow must be accelerated in the direction of travel of the fabric rope, for which purpose the transport medium flow requires considerable energy, which must be supplied by the blower that transports it. However, it is desirable, particularly when spraying fabric in rope form, to provide a large flow of liquor through the delivery nozzle in order to shorten the spraying time and achieve good spraying results.

Disclosure of Invention

The object of the invention is therefore to indicate a way which allows a better spray application of the treatment liquid to the fabric rope in a simple manner.

To achieve this object, the wet processor according to the invention has the following features.

Wet treatment machine for textile fabrics in rope form, having: a closed container; a venturi delivery nozzle system which can be supplied with a delivery medium flow in order to drive a continuous fabric rope circulating in the vessel in a predetermined circulating direction and which has a nozzle annular gap through which the delivery medium flow flows, which nozzle annular gap is delimited on one side by a nozzle cone with a through-passage; a winding device, which is arranged before the conveying nozzle system along the route of the fabric rope and can introduce the corresponding fabric rope into the conveying nozzle system through the winding device; a device for spraying a treatment liquid onto a fabric rope is located in a section of the fabric rope path between the area of the take-up device and the nozzle ring gap of the delivery nozzle system.

The new wet treatment machine is equipped with a device for spraying a treatment liquid onto the fabric rope in a section of the fabric rope path between the area of the take-up device and the nozzle ring gap of the transport nozzle system, which device allows the treatment liquid to act on the fabric rope in addition to or alternatively to the device already present in the area of the transport nozzle system for spraying a treatment liquid onto the fabric rope, so that the fabric rope enters the area of the nozzle ring gap of the transport nozzle system already with the treatment liquid. By spraying the treatment liquid onto the fabric rope between the area of the reeling device and the nozzle loop gap, a particularly effective wetting of the fabric rope before it is treated with the treatment liquid in the transport nozzle system is achieved, because the path of the fabric rope between the reeling device and the transport nozzle system, which is usually horizontal or slightly inclined with respect to the horizontal, is relatively short, so that the fabric rope carries a large part of the sprayed treatment liquid into the transport nozzle system. The amount of treatment liquid sprayed onto the fabric rope in the area of the delivery nozzle system itself can thus be reduced.

If the spraying device for spraying the treatment liquid onto the fabric rope is arranged in such a way that the treatment liquid flowing out of it has at least a movement component in the running direction of the fabric rope. Thereby reducing the energy consumption required for accelerating the droplets in the running direction of the fabric rope, since the sprayed treatment liquid has already been accelerated in the running direction of the fabric rope. This results in a reduction in the load on the circulation circuit of the gaseous transport medium and an acceleration of the circulation of the fabric rope. Furthermore, the passing fabric is protected, since the drops of the treatment liquid no longer drip onto the surface of the fabric rope perpendicularly to the running direction of the fabric rope.

In a practical embodiment, the treatment liquid spraying device can have a spraying device in the region of the winding device, which has a spray nozzle. The spray nozzle has an outlet axis in the region of its nozzle outlet, which is at an angle of less than 90 DEG to the running direction of the fabric rope.

A simple design is achieved if the winding device has at least one winch which can be rotated about a rotational axis and the treatment liquid spraying device opens, for example, into the region above the winch, so that the sprayed treatment liquid flows downward and emerges onto the rope-shaped fabric passing by. Alternatively and/or additionally, the treatment liquid spraying device can also open into the region between the winch shaft and the nozzle cone of the delivery nozzle system, if this is possible in the case of existing constructions.

The new wet treatment device may additionally or alternatively also have means for spraying the treatment liquid into the through-channels of the nozzle cone, which open around the channel walls enclosing the through-channels. By means of this spraying device, the treatment liquid, i.e. the treatment agent, is sprayed onto the fabric rope passing through the delivery nozzle separately from the delivery medium flow. Here too, the spraying of the fabric rope with the treatment liquid is independent of the speed of the transport medium flow flowing into the annular gap, which facilitates the transport of the fabric. Since the spraying device is arranged in the area of the nozzle cone, the fabric rope has already been pretreated with the treatment liquid sprayed out of the spraying device if it enters the annular gap and is acted upon there by the transport medium. Since the spray devices are distributed around the wall of the through-channels, the fabric rope passes through a treatment liquid curtain a, which is arranged concentrically around the nozzle bore, when passing through the through-channels of the nozzle cone. This gives a very gentle treatment of the fabric with the treatment liquor.

In a preferred embodiment, the spraying device opens relative to the longitudinal center line of the through-channel in such a way that the treatment liquid flowing from the inside into the through-channel has a movement component in the direction of travel of the wet web. For this purpose, the spraying device advantageously opens at an angle to the longitudinal center line, the apex of which points in the direction of travel of the fabric. By these measures, it is achieved that the treatment liquid curtain a has a component in the direction of travel of the fabric, which can be made so great that it has approximately the speed of the passing fabric rope. This makes it possible, as described above, for the treatment liquid fed into the through-passage by the spraying device not to be accelerated first by the fabric rope which carries it through, which causes a braking action on the fabric rope.

In a preferred embodiment, the injection device has injection channels which open into the through-channel distributed around the channel wall, wherein the outlets thereof are preferably distributed uniformly over the circumference of the through-channel. Alternatively and/or additionally, however, the spraying device can also have at least one annularly distributed annular gap through the wall of the through-channel, which surrounds the passing fabric rope and sprays the treatment liquid uniformly onto the fabric rope. In any case, however, as described above, the treatment liquid is sprayed gently onto the fabric rope, and the desired felting or penetration (einmassienna) of the treatment liquid into the fabric is carried out by the transport medium flow as the fabric rope passes through the subsequent high-force section of the transport nozzle, which high-force section (Intensivstrecke) extends from the annular gap in the direction of travel of the fabric. The treatment liquid does not need to be diverted by spraying it in the nozzle cone. The treatment liquid reaches directly and 100% of the flow of the passing fabric, since no throwing-off or separation of droplets takes place, which is unavoidable if the treatment liquid is added to the flow of the conveying medium.

The delivery nozzle can be enclosed in the annular gap region in the usual manner by a suitable nozzle housing, which is connected to a delivery medium source by a corresponding line. In particular, in so-called multi-reservoir machines, in which a plurality of delivery nozzles are associated with a single container in a side-by-side arrangement, the delivery nozzles of the nozzle system can be arranged with their annular gaps horizontally in a common delivery medium distribution chamber, which is filled with the gaseous delivery medium. The distribution chamber can be suitably embodied in an elongated transport medium distribution box, which is connected to the transport medium source and in which the transport nozzles are directly accommodated.

Detailed Description

The high-temperature (HT) piece dyeing machine shown schematically in FIG. 1 has a cylindrical pressure-resistant container 1 into which a working opening 3 is accessible, which can be closed by a cover 3, through which a fabric rope 4 can be introduced. The fabric rope 4 is guided by means of an external drive winch 5 into the venturi transport nozzle 6, to which a folding machine 7 is connected, the folding machine 7 folding the fabric rope 4 exiting from the transport nozzle 6 into a storage 8, the endless fabric rope being withdrawn again from the storage 8 by means of the winch 5, wherein the fabric rope 4, as can be seen from fig. 1, creates a substantially vertical fabric rope path between the storage 8 and the winch 5, the winch 5 and the transport nozzle 6 being mounted on a partial housing 9, which is connected to the container 1 in a liquid-tight manner. The fabric rope 4 is connected at its ends to form a continuous fabric loop after being introduced through the opening 3.

The delivery nozzle 6 is supplied with a gaseous delivery medium flow which circulates the passing fabric rope 4 in a circulating direction indicated by the arrow 10. The transport medium is in this case air or an air-steam mixture, which is drawn out of the container 1 by means of a blower 11 and a suction line 12 and is fed to the transport nozzle 6 by means of a pressure line 13.

A dye liquor bath is arranged below the vessel 1, which comprises a dye liquor screen 15, which is connected to a suction pipe 16 of a dye liquor circulation pump 17, whose pressure line 18 comprises a heat exchanger 19 and leads via a control valve 20 and a line 21 into the delivery nozzle 6. The liquor circulation pump 17 allows the treatment liquor drawn from the vessel 1 to circulate through the delivery nozzle 6 and the vessel 1. The circulation path is indicated in dark in fig. 1. Parallel to the heat exchanger 19 and the liquor circulation pump 17 is a bypass line 22 which contains a shut-off valve 23 and connects the liquor basin 14 to the pressure line 21.

Finally, an additive container 24 is provided, which contains the chemical treatment agent in the form of an aqueous solution, emulsion or Dispersion (Dispersion) and which can be fed via a treatment agent pump 25 and a connecting line 26 into the suction line 16 of the liquor circulation pump 17. As can be seen from fig. 2, the piece dyeing machine is configured as a multi-reservoir machine, which in the illustrated case comprises four reservoirs 8 arranged side by side in the axial direction of the cylindrical container 1, each reservoir 8 being associated with a delivery nozzle 6. The four delivery nozzles 6 constitute a delivery nozzle system. In this nozzle system, each delivery nozzle 6 is assigned, in the manner visible in fig. 1, a driven winch 5, the drive of which is not illustrated in detail, the winch 5 together with its drive and the partial housing 9 forming the winding device.

Piece dyeing machines operating aerodynamically as described in this connection are well known.

According to the invention, the piece dyeing machine is provided with an auxiliary device for spraying the treatment liquid on the fabric rope 4 in the area of the winding device 4. For this purpose, a treatment liquid nozzle 29 (fig. 3) is assigned to the winch 5 mounted in front of each delivery nozzle 6 and rotatable about a rotation axis 28 in the housing 9, said nozzle being arranged in a connection fitting 30 of the housing 9. The process liquid nozzles 29, which in some cases are embodied as shower or spray nozzles, are connected to the process liquid pressure line 21 via a line 31 (fig. 1) and a regulating valve 32. As can be seen from fig. 2, the lines 31 leading to the four delivery nozzles 6 are connected in parallel to a collecting line 33, which is connected to the pressure line 21.

Fig. 3 shows that the treatment liquid nozzle 29 is bent in the outlet region from the vertical in a direction close to the direction of travel 10 of the fabric rope in such a way that the nozzle outlet axis 34 forms an acute angle with the direction of transport 10 of the fabric rope and the apex thereof is located in front in the direction of travel of the fabric. This achieves that the treatment liquid emerging from the nozzle 29 has a movement component in the direction of travel 10 of the fabric rope 4.

As shown in fig. 3, the delivery nozzle 6 has a nozzle cone 35 with a concentric through-passage 36 for the fabric rope 4, to which a diffuser 37 is connected in the running direction of the fabric rope to form an annular gap 38 with the nozzle cone 35. The annular gap 38 is arranged in a surrounding tubular nozzle housing 39 into which the process fluid pressure line 21 and (not shown in fig. 3) the blower pressure line 31 open.

The outlet of the treatment liquid pressure line 21 in the nozzle housing 39 is realized by an outlet, not shown in detail in fig. 3, which can likewise be arranged in the direction of circulation 10 of the fabric rope 4, from which outlet the sprayed drops of treatment liquid are carried by the conveying medium flow into the annular gap 38.

In addition to or alternatively to the injection pressure line 21 leading into the nozzle housing 39, it is also possible to arrange the injection channels 40 in the nozzle cone 35, as shown in fig. 3, which open into the through-channels 36 uniformly around the through-channels. As can be seen from fig. 3, the jet channel 40 is arranged with its center line at an angle to the direction of travel 10 of the fabric in such a way that the treatment liquid jet emerging from it has a movement component in the direction of travel 10 of the fabric rope. It can be seen that the axis of the injection channels 40 (only one of which is shown) makes an angle of less than 90 with the axis of the through-channel 36.

The spray channel 40 starts from an annular channel 410 which is arranged on the nozzle cone 35 and which is connected via a line 21a to the pressure line 21 of the liquor circulation pump 17.

In operation, the treatment liquor, which is circulated in a circulation path indicated in dark in fig. 1 and which in some cases is charged with a special treatment agent, for example a dye, from a liquor preparation vat 24 and heated in a heat exchanger to the respective treatment temperature required, is sprayed by a liquor circulation pump 17 via a pressure line 21 into the nozzle housings of the individual delivery nozzles and there is sprayed together with the delivery medium stream onto the passing fabric rope 4. At the same time, the treatment liquid is sprayed onto the fabric rope 4 via the pipe 21 and the spray nozzles 29 in the region of the respective winch 5 before the fabric rope 4 enters the spray cone 35. The distribution of the treatment liquid to the nozzle housing 39 and the treatment liquid nozzle 29 can be adjusted by means of two regulating valves 20, 32 (fig. 1). As already mentioned, the treatment liquid can also be sprayed onto the fabric rope 4, either additionally or alternatively via the ducts 21a and the spray channels 40 in fig. 3.

In the illustrated embodiment, the treatment liquid nozzle 29 opens above the winch 5, but the arrangement can also be such that the outlet of the treatment liquid nozzle 29 is located in the region between the axis of rotation 28 of the winch 5 and the inlet of the fabric rope into the nozzle cone 35. This can be achieved by a pipe 31a, which is schematically indicated in fig. 1 by means of a dashed line, comprising a regulating valve 32 a. It is conceivable to spray the treatment liquid onto the fabric rope in a planar distribution before the fabric rope enters the nozzle cone 35 or at several locations in the section between the axis of rotation 28 and the nozzle cone 35.

In fig. 4 to 6, as a further example of a wet processor according to the invention, an aerodynamically high-temperature (HT) piece dyeing machine is shown, wherein in fig. 4 only one vessel 1 is shown, which is designed as a closed cylindrical high-pressure vessel. The machine is a so-called multi-reservoir machine and likewise comprises four venturi delivery nozzles 6, which are arranged axially next to one another in a horizontal manner in the container 1. The winch 5 associated with each nozzle 6 is arranged here in such a way that a substantially horizontal path of travel of the fabric rope 4 is produced between the winch 5 and the delivery nozzle 6.

The same parts as in fig. 1 to 3 are provided with the same graphic symbols and are not described again. Machine parts not essential to the invention are not shown in the figures. Reference may also be made for details, for example, to EP0945538a 1.

The fabric rope 4 is driven in the respective delivery nozzle 9 by passing a gaseous delivery medium, i.e. usually air, steam or an air-steam mixture, through it. For this purpose, a blower 11 is provided in the container 1 in the region of a container end face, which is driven by an electric motor 11a and has a pressure channel 13 which opens into a transport medium distributor box 41 which extends substantially over the axial length of the four reservoirs 3. The blower 11 is connected at the suction side to a suction tube 42 concentric with the cylindrical container 1, which extends over the axial length of the container 1 and has corresponding perforations in its wall.

The conveying medium distributor box 41 is closed at one end 150 and is connected at its opposite end to the pressure line 13 of the blower 11. The distributor box has a substantially rectangular structural shape (see fig. 2). The upper top wall 43 is designed to be dome-shaped in order to match the curvature of the outer envelope surface of the container 1.

Four delivery nozzles 6 are mounted in parallel axial alignment in a delivery medium distribution box 41, in particular as can be seen from fig. 5 and 6. Each delivery nozzle 6 has a nozzle cone 35 which encloses a concentric annular gap 38 with a part of a concentric diffuser 37 which widens into a mixing nozzle 37a, through which gap the delivery medium flows uniformly into the diffuser 37. The nozzle cone 35 contains a concentric through-passage 36 for the fabric rope 4, wherein the through-passage 36 consists of a cylindrical section 45 and a funnel-shaped expanded concentric section 46 forming the entrance to the fabric rope, to which funnel-shaped expanded section 46 the cylindrical section 45 is attached.

As can be seen from fig. 5, the delivery nozzles 6 are mounted in the delivery medium distributor box 41 with their nozzle longitudinal axes oriented horizontally in such a way that their nozzle cones 35 and their diffusers 37 each pass sealingly through box side walls 46 facing away from one another.

The cavity, which is enclosed during operation by the transport medium distributor box 41 and in which the annular gap 38 of the transport nozzles 6 is contained, is supplied with transport medium by the blower 11, so that all 4 transport nozzles 6 transport their respective fabric rope 4 uniformly. The feed medium distributor box 41 with the installed feed nozzles 6 operates on the so-called common rail principle and allows a very uniform feed of feed medium to all feed nozzles to be ensured.

As can be seen in particular from fig. 6, the nozzle cone 35 of each delivery nozzle 6 is equipped with means for injecting treatment liquid into the through-channel 36, which (as can be seen by the arrows 240) open uniformly distributed around the wall of the through-channel 36 in the circumferential direction. These injection devices have injection channels 40 which are formed in the nozzle cone 35 and open into a funnel-shaped widening section 46 of the through-passage 36. The outlets of the injection channels 40 are evenly distributed in the circumferential direction on the breakthrough channel wall as described above. Fig. 6 shows that the spray channels are arranged obliquely with respect to the longitudinal center line 47 of the nozzle in such a way that their axes each enclose an angle with the longitudinal center line 47, the apex of which points in the direction of travel 10 of the fabric. On its side facing away from the outlet, the spray channel communicates with the interior of an annular duct 410 which is arranged around the nozzle cone 35 and surrounds it and which is connected to a duct 21a which is not shown in detail in fig. 3.

The treatment liquid entering the penetration passage of the nozzle cone 35 from the spray passage 40 comes into close contact with the passing fabric rope 4 while flowing out of the spray passage 40. Since the spray channel 40 is arranged obliquely to the longitudinal axis of the nozzle in the direction of travel of the fabric, the treatment liquid flowing out of the spray channel here also has a component of movement in the direction of travel of the fabric, which supports the transport of the fabric in rope form. The annular channel 410 is fed with the treatment liquid at a pressure chosen such that the speed of the component of the treatment liquid flowing into the through channel 36 in the direction of travel 10 of the fabric is substantially equal to the speed of travel of the fabric rope 4. But the velocity of the motion component may also be large or small depending on the process conditions at the time.

Alternatively, the injection channel 40 can also be replaced by an annular gap which is distributed annularly and which communicates with the annular channel 410. Embodiments are also conceivable in which a plurality of rows of injection channels 40 arranged next to one another in the axial direction of the through-channel 36 and/or a plurality of correspondingly arranged annular gaps are present.

In principle, it is also possible to arrange the injection channel or the annular gap in the cylindrical section 45 of the through-channel 36, which should be pointed out for the sake of order.

In this embodiment, as in fig. 1, other devices for spraying the treatment liquid onto the fabric rope can also be provided, which open into the path of travel of the fabric rope between the winch 5 and the nozzle cone 35, wherein the winch 5 is also arranged directly in the region of the opening 2 in the container 1, as shown in fig. 6.

Finally, it should be pointed out that the invention is not limited to use in an aerodynamic wet processor. It can also be used in jet wet-processing machines which work with liquid transport media.
