Abstract

Known nozzle devices use the recoil of the fluid to be ejected at nozzle openings in a rotor in order to set this in rotation and spatially deploy the fluid. Thus, regulation of the rotational speed is possible only as a function of the configuration of the nozzle openings. This is disadvantageous for an application-related design of the spray pattern. The nozzle device (1) for spatially discharging fluids has a flow part (3), via which a fluid to be sprayed enters the nozzle device, a rotor part (2), which is rotatably arranged in relation to the inflow part (2) and surrounds the same, and a bearing element (4) which serves adjacent to inflow part (3) and rotor part (2) for the rotatable mounting of the rotor part (2). By oppositely mounted off-center openings (24) and (25), the fluid flows into the space between the rotor part (2) and the flow part (3) and generates at least two flows, each with opposite directions (28) and (30). The difference between these flows (28) and (30) determines the direction (29) and speed of rotation of the rotor part. The fluid is applied spatially with application-defined spray pattern via the nozzle openings (15) and (16). The nozzle device (1) is suitable for cleaning, steam disinfecting or lubricating the insides of tanks or containers, and the defined admixing of fluids in atmospheres.

Description

Field of use:

The invention relates to a rotating nozzle device for the spatial application of fluids with a definable beam characteristic.

Specifically, a purely fluid-driven nozzle device, which has a very accurate speed regulation and at the same time uniform tumble-free rotational movement through its geometric design.

State of the art:

Usually, such rotary nozzle devices consist of a connector part, rotor part and holding part. Through the connector part, the nozzle device is connected to a pipe system, which supplies them with the fluid to be sprayed. The rotor part is rotatably supported by connector and holding part. By means of the medium to be sprayed, the rotor part of the nozzle device is brought into a rotating movement, more precisely by the position of the actual nozzles on the rotor part.

The actual nozzles are openings referred to below as nozzle openings which are formed in the rotor part, or openings on receiving pins which are introduced into the rotor part. The design of these openings defines various beam characteristics, so-called spray patterns, such as spray patterns. Flat jet (fan-shaped emerging fluid streams) or full jet and by means of their arrangement on the rotor part, during its rotation, different spatial spray covers, such.: 360 °, 270 ° up or down or 180 ° up or down, can be generated.

Typically, nozzle devices such as these are used in defined spatial application of fluids in biological, chemical-technical processes and process-relevant steps such as cleaning, sterilization, lubrication and Trennmittelbeaufschlagung the inside of tanks or similar containers.

In order to perform these tasks in satisfactory quality and the shortest possible time, a uniform rotational movement with controllable speed of the rotor part is required, while possible independent of pressure and flow rate of the fluid to be sprayed. The rotational speed should therefore be adaptable and have no influence on the jet characteristics of the nozzle openings.

An example of the nozzle devices described is in EP 2 448 681 B1 to find. Here, the rotor part, the so-called nozzle head or nozzle body, rotatably mounted on connector and holding part and the bearing element is connected to operate the nozzle device by means of a spring connector with a pipe system for fluid supply. In order to offset the nozzle head in the direction of rotation, the actual nozzles are offset laterally in the radial direction here as well. A regulation of the speed is not the focus of this nozzle device and this is at best possible by defined friction surfaces on the plain bearings of the rotor part. The main intention of this nozzle device is a hygienic design.

From the DE100 06 864 B4 is a rotating tank cleaning nozzle known. The nozzle has a cylindrical nozzle body with a fluid drive, through a laterally offset in the radial direction nozzle mouth. By which the cleaning fluid exits fan-shaped in the environment and thereby generates a drive torque for braking the nozzle body.

The nozzle body is rotatably mounted on a fluid inlet part which has a swirl generating device, in which the fluid is conducted from the inlet opening through central bores into lateral grooves. These grooves are helically formed on the periphery of the fluid inlet part in the space of the same and the nozzle body. As a result, a rotating flow is generated on the inside of the nozzle body, which drives the nozzle body due to friction effects. This drive is opposed to the drive torque of the nozzle orifice in the nozzle body, whereby an inhibitory effect on the rotation of the same is achieved.

The nozzle has in practice reinforced the use of fluids with water-like properties, however, the generation of the braking torque with the nozzle body has the consequence that it can not be in mechanical equilibrium with respect to its axis of rotation, which causes a tumbling rotational movement in reality. In order to limit this to a nozzle-functional minimum, it is indispensable to tolerate tightly the slide bearings on which the nozzle body is mounted with respect to the dimensions.

Thus, the function of the nozzle for particulate and polluted cleaning fluids very problematic or not given. This also applies to the use of higher viscosity media, such as oils, as well as very low viscosity media, such as gases and vapors.

Furthermore, the decoupling of the opposing moments has the disadvantage that the design of the nozzle orifice is limited to the nozzle body. These nozzle mouths must be dimensioned and designed so that the torque generated during operation is matched to media properties and operating parameters. The choice and realization of a specific beam characteristic is possible only to a very limited extent.

Since the rotating drive flow Helix like flows away from the swirl generating device, a considerable pressure on the sliding bearing, which is remote from the swirl generating device. In order to reduce this and in addition by the real tumbling rotational movement on the bearing induced friction to a functional level, it is necessary to form a defined friction surface between the nozzle body and this camp.

Further examples wherein nozzle device consisting of connector, holding and rotor part are known from CH-699 422 B1 and FR-2 500 334-A1 , Here, the rotation is also generated by inclined in the radial direction nozzle openings in the rotor part.

Furthermore, from the U.S. Patent 1,480,507 and the WO 97/21493 Nozzle devices, here lawn sprinklers, known. In this case, a rotating flow is generated by means of a swirl generating device in the rotor part interior, however, rotational speed regulating counterparts are not provided.

Disadvantages of the prior art:

Proceeding from this, during the rotation of the known nozzle devices, mechanical friction occurs at certain points due to the design of the individual parts of the nozzle device, which slows down the speed of the nozzle device during operation and thus allows a regulation of the rotational speed within a certain range.

Since this area is essentially determined by geometrically predetermined friction surfaces, the optimum speed regulation is limited to only a small field of the operating parameters of the nozzle system. Which equates to a disqualification for many applications.

Thus, the use of these known drive mechanisms is problematic or even impossible for fluids with gas-like characteristics such as vapors or hot air (a common case of sterilization) or fluids with higher viscosity such as oils or gel-like media, since this is due to certain lubricating behavior of the media to be sprayed the necessary Friction is adversely affected.

Furthermore, the rubbing of these particular geometric surfaces causes material abrasion which can be hindering or even harmful to the field of application of the nozzle system. Since the resulting particles can get into the medium to be sprayed and contaminate it or be problematic for the following processes.

The friction creates heat, which in turn has an influence on the rotational behavior of the nozzle device because the friction depends inter alia on material pairing and rubbing surfaces and in extreme cases completely prevents the rotation. This heat development can additionally exceed process-relevant limits and thus can be a danger to the process or may not be suitable for certain applications, such as in applications in the ATEX area.

Another disadvantage of the known nozzle device of this type is the fact that the rotor part very often can not be reversibly installed in the nozzle device, because the friction surfaces must be defined to ensure a certain rotation. This presents a source of error in disassembly and reassembly of the nozzle device for maintenance purposes.

Object of the invention:

The object of the invention is to ensure a uniform rotational movement of a rotating nozzle system with constant, controlled speed, almost pressure-independent, driven only and only by the fluid to be sprayed, controlled and regulated. Wherein the rotor part has a mechanically stable, non-tumbling rotational movement in order to ensure an almost unrestricted realization of certain beam characteristics and the rotation is independent of mechanical friction between components of the nozzle device.

Solution of the task:

This object is achieved by a device having the features of claim 1.

Advantages of the invention:

The nozzle device according to the invention described below can be made of materials suitable for the purpose, such as metal, plastic, ceramic and glass, or of mixtures be made this and connected via a screw, welding or using a spring connector in conjunction with through holes to a piping system. Likewise, the viscosity of the media to be sprayed has no significant influence on the rotational behavior whereby this nozzle device for the use of critical media such as steam or high viscosity oils is particularly well suited, as well as for foreign body sensitive applications, as it ensures almost no mechanical abrasion.

Description of exemplary embodiments:

The present invention relates to a rotary spray device which is driven by the fluid to be sprayed. In which the fluid is introduced into the preferably rotationally symmetrical inflow part mostly via a bearing element through a pipeline. On the circumference Anströmteil at least two off-center, each inclined in opposite radial direction openings are formed whose alignment axis does not intersect the axis of rotation of the rotor part. Through these openings, the fluid flows jet-shaped into the at least one intermediate space between the rotor part and the flow part, where it impinges tangentially on the inside of the rotor part and be deflected in at least two different directions.

As a result of which the inflowing fluid forms at least two flows in the at least one intermediate space between rotor part and inflow part, which differ in intensity and direction and set the rotor part into rotation by entrainment effects. The rotational speed and direction of rotation of this rotation is determined and controlled by the difference of these at least two flows. They induce a resulting moment on the rotor part, which is almost constant over the possible operating parameters, such as pressure, mass flow, inflow characteristic, etc., because these flows depend on the same parameters.

This offers the possibility of the actual nozzles on the rotor part centric, that is, whose axis with respect to the alignment of the nozzle openings intersects the axis of rotation with respect to the rotor part. Thus, the actual nozzles themselves are decoupled from the rotational behavior and can be designed exclusively for a defined beam characteristic and dimension, size as a function of flow.

Preferably, flow-causing openings are formed radially symmetrically in the inflow part in such a way that the fluid jet emerging from them always strikes the inner wall of the rotating rotor part and the actual nozzles are only flowed through by the resulting fluid flows. The rotor part itself has such a mechanically stable non-tumbling rotation during operation and is mounted purely fluidically in the inventive design. Which reduces friction and wear to a negligible minimum.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

The gap 8th is from the rotor part inner surfaces 13a and 13b formed by a radially inward-formed projection 14 are divided, and the cylindrical Anströmteilaußenfläche 12 limited. The radially inwardly formed projections 11 and 14 preferably have a larger inner diameter relative to the radially inwardly formed projection 9 , preferably the.

The actual nozzles 15 are distributed radially symmetrically along the axis of rotation 5 preferably elongated openings on the rotor part outside 17 to the rotor inner surface 10a whose orientation 18 according to 4 the axis of rotation 5 to cut. Analogously, the actual nozzles are nozzles 16 distributed radially symmetrically along the axis of rotation 5 preferably elongated openings on the rotor part outside 17 to the rotor inner surface 13a whose orientation 19 according to 5 the axis of rotation 5 to cut. The cylindrical rotor inner surfaces 20a and 20b , as well as the lead 9 preferably have the same smallest inner radius and have a distance from the Anströmteilaußenfläche 12 on, whereby a fluidic storage is generated during operation. The entire outer contour of rotor part 2 is preferably free of burrs and edges.

For rotatable mounting of the rotor part 2 serves the flow part 3 which is at one end with a fluid inlet 22 is provided by an axial bore 21 is formed. It is with respect to the axis of rotation 5 formed rotationally symmetrical and has on the fluid inlet 22 opposite side an annular bearing surface 23 on, as a projection against the Anströmteilaußenfläche 12 is formed for axial mounting of the rotor part 2 serves.

Transverse to the flow part outer surface 12 in the flow part 3 at least one trained lateral opening 24 in at least one direction 28 against the radial direction 29 inclined, with at least one fluid inlet 22 and at least one further formed lateral opening 25 in at least one more direction 30 in the same radial direction 29 inclined, with at least one fluid inlet 22 are connected. The alignment axes 26 and 27 these openings 24 and 25 cut the axis of rotation 5 not, according to 4 and 5 ,

Preferably, the alignment axes 26 the openings 24 with respect to the axis of rotation 5 radially symmetrical and in the assembled state of the nozzle device 1 at the height of the rotor part inner surface 10b with respect to the axis of rotation 5 arranged.

Analogously, the alignment axes are preferably 27 the openings 25 with respect to the axis of rotation 5 radially symmetrical and in the assembled state of the nozzle device 1 at the height of the rotor part inner surface 13b with respect to the axis of rotation 5 disposed

To ensure idling of the nozzle device after completion of operation is the fluid inlet 22 forming hole 21 designed as a blind hole and ends preferably on the lower edge 31 the openings 25 in the flow part, according to 2 ,

After the lead 32 this is the fluid inlet 22 remote end of the Anströmteils formed in Rundlicher manner and is part of the outer contour of the nozzle device 1 , On the side of the fluid inlet 22 is an external thread 33 for the screw connection 34 with the bearing element 4 trained and ends with a protrusion-like shoulder 35 to the flow part outer surface 12 ,

In the assembled state, the rotor is axially through the roundish bearing element outer surface 36 secured and rotatably mounted fluidly. The bearing element 4 is with respect to the axis of rotation 5 rotationally symmetrical and has according to 3 a trained internal thread 37 for connection to a casing, whereupon a conical inner surface 38 for the most part No flow disturbance as a transition to the trained internal thread 37 follows. On the internal thread used for connection to a piping 37 facing side, is the bearing element 4 with an outer cylindrical surface 39 provided by the key areas 40 is interrupted, which mirrored with respect to the axis of rotation 5 and are preferably formed at a distance in dimension of a standardized wrench size to each other. From the lateral surface 39 is a roundish conical transition 41 to the cylindrical outer surface 42 on the for connecting to the Anströmteil 4 serving internal thread 37 facing side.

To adapt to the particular application process, the nozzle device 1 be made of fluid and application conditions compatible materials or combinations of such, such as metal, plastic, ceramic or glass.

The operation of the embodiment of the invention described nozzle device 1 in 1 - 5 is as follows:

The fluid to be sprayed passes over the bearing element 4 into the fluid inlet 22 from where first part of the fluid through the openings closer to the fluid inlet 24 as fluid jets in the gap 7 between rotor part 2 and on-flow part outer surface 12 stream. This in the gap 7 incoming fluid jets hit because the alignment axes 26 the axis of rotation 5 do not cut and the openings 24 are inclined towards the radial direction, preferably tangentially to the rotor part inner surface 10b and are distracted at the same. Due to the pulse transmission and entrainment effects occurring in this case is on the rotor part 2 generates acting torque.

The not through the openings 24 flowing part of the fluid to be sprayed flows as fluid jets through the openings 25 in the gap 8th , Because the alignment axes 27 the axis of rotation 5 do not cut and the openings 25 against the direction of the openings 24 are inclined towards the same radial direction, meet these fluid jets, preferably tangentially to the rotor inner surface 13b and are distracted at the same. In this case occur analogous momentum transfer and deadweight, the other on the rotor part 2 generate acting torque counteracting the first torque.

Direction of rotation and rotational speed of the rotor part 2 is mainly determined by the difference of these torques, which predominantly by the sum of the smallest freely flowed through the cross section of the openings 24 or 25 with the same inclination in the radial direction and by their distance from the fluid inlet 22 along the axis of rotation 5 is determined.

Preferably, the rotor inner surfaces 10b and 13b which of the openings 24 or. 25 exiting fluid jets are primarily taken without nozzle openings, such as 15 and 16, provided for a possible clear opening overlap of the rotor part 2 and oncoming part 3 , which can lead to a so-called hydraulic short circuit during operation of the nozzle device to prevent. The rotor inner surfaces 10b and 13b can be provided with mitnahmeeffektunterstützenden surface textures or internals, such as longitudinal ribs.

The bearing element 4 was on a the fluid bearing ring surface 36 owning ring 45 reduced, this encloses with play the Anströmteilaußenfläche 12 and becomes relative to along the axis of rotation 5 from spring connector 44 held.

Instead of the inwardly formed projections 9 . 11 and 14 go the rotor part inner surfaces 10a . 10b . 13a and 13b transitionless into each other, creating the spaces between 7 and 8th the at least one gap 46 form.

The nozzle openings 15 and 16 replaced the nozzle openings 47 These are relative to their alignment axes 48 rotationally symmetric and with respect to the axis of rotation 5 arranged radially and axially at regular and / or stochastic intervals, in the rotor part 2 educated. When flowing through a nozzle opening 47 occurs to be sprayed fluid as a compact jet, so-called full jet into the environment.

The in the flow part 3 hole formed as a blind hole 21 runs at the fluid inlet 22 averted end conical on through holes 48 with associated alignment axes 50 to which, through the round oncoming part outer surface 49 lead into the free.

The advantage of in 6 to 10 illustrated embodiment of the nozzle device 1 is that these threadless, so smooth-walled trained and low gap, in particular can be mounted without labyrinth columns and all existing columns and niches are flowed through by the fluid, which hardly set particles or the like and after stopping the fluid supply to the fluid inlet 22 Also, no accumulations of the fluid to be sprayed can remain, which is the compliance with guidelines of hygiene standards such. For example: 3A and FC. This allows in particular the applications in the pharmaceutical and food sector.

In 11 to 16 Further embodiments of the nozzle device according to the invention are illustrated. Insofar as there are similarities with the above-described nozzle device in construction and / or function, reference is made to the above description with reference to the same reference numerals.
