Definitions

  • the invention relates to a rotary cleaner according to the preamble of the first claim.
  • Rotating cleaners are used to clean the interior of containers such as tanks. They have a rotating spray body with one or more outlets from which a designedsfiuid emerges. By the rotation of the spray body, if possible, the entire inner wall surface of the container is wetted with make-fiuid.
  • These cleaners are mainly used in hygienic applications, for example in the food industry, but they are also used in other industries.
  • the rotating spray body must be rotatably supported in the housing of the cleaner.
  • ball bearings are known in a type of this type of cleaner.
  • Such storage for example, DE 101 30 316 C1 before.
  • Balls which are arranged between on one side on a rotating assembly and on the other hand provided on the housing running surfaces, provide for a rotatable support in the axial and radial directions.
  • the rotation is generated by the fluid flowing into the cleaner, in which it flows against a provided inside the spray body twisted leaf spring.
  • the rotatable assembly with ball bearings to support rotatable is also shown in DE10 2005 015 534 B3,
  • the fluid emerging from the spray body can be used to produce the rotation of the spray body. This is illustrated for example in DE 10 2011 078 857 A1.
  • the rotation is created by directional entry of the fluid into the raised spray body and through exit from the spray body.
  • Another outlet nozzle is used for braking.
  • a cleaner with plain bearing is the GB 1604650 A before.
  • a cylindrical part is arranged between housing and shaft of the rotating assembly and acts as a wheel bearing.
  • a flange-like portion is provided, which causes a sliding bearing in the axial direction.
  • the rotating assembly is driven by a ball, which is abutted on the one hand by the cleaning fluid and, on the other hand, presses against a projection which is provided on the rotating assembly.
  • the cylindrical bearing part with its flange-like portion which acts as part of the plain bearing and belongs to a radial and an axial bearing can be made of Teflon. This is proposed by DE 101 43 468 C1, which also relates to improvements in terms of cleanability and rotary drive.
  • a rotary cleaner with a first, radial and a second axial slide bearing as described herein and with a spray body driven by recoil of an exiting fluid is known under the trade name Turbo SSB.
  • the invention is based on the object to provide a rotating cleaner which is easy to clean and whose rotating assembly has good rotational properties.
  • the rotating assembly of the cleaner is rotatably supported by a sliding bearing having a rotating and a stationary bearing surface. These bearing surfaces are formed as contiguous surfaces and designed to provide support the assembly is effected with the spray body in the radial and axial directions simultaneously by the sliding bearing created by the bearing surfaces.
  • Such a slide bearing acting as an angular bearing improves the running of the spray body by improved centering.
  • the production is simplified due to the smaller number of surfaces to be manufactured exactly. Compared to the prior art, therefore, a higher accuracy of the sliding bearing is easier educable. The higher accuracy also improves the running and turning properties. With fewer components and simpler geometry, the cleaner is easier to clean and less susceptible to contamination, making it easier to meet the applicable 3A and EHEDG standards.
  • a contiguous surface is to be understood in particular as an area that is free of steps, steps or kinks.
  • a design which is easy to produce in terms of its effect provides for rotating and stationary bearing surfaces to be conical in each case. This design results in a plain bearing with uniform power and uniform leadership property, resulting in a quiet Laufbiid. A quieter run increases, among other things, the life of the cleaner and improves the cleaning effect achieved.
  • a particularly uniform distribution of axial and radial forces and a resulting particularly smooth running image arise in an embodiment in which the generators of the conical bearing surfaces form an angle between 40 degrees and 45 degrees with a rotation axis.
  • the running properties of the sliding bearing also depend on the supply of a fluid in the gap between bearing surfaces.
  • An embodiment which is advantageous in this respect provides for providing a feed opening in the shaft through which bearing fluid enters into the bearing gap of the sliding bearing. A more even rotation and the resulting smooth running image arises after a development that provides a guide sleeve in the cavity, which is in sliding contact with the shaft and limits its play in an axial direction.
  • Another development with regard to the fluid guidance of the bearing groove provides for arranging an outlet opening in the housing, which produces a fluid connection between the bearing gap and an environment of the rotating cleaner. In this way, bearing fluid can escape from the bearing gap, which allows the flow of fresh fluid into the bearing pad. The fluid film between the bearing surfaces becomes this way more uniform, moreover, the draining fluid causes a cleaning of an outer wall of the cleaner.
  • an intermediate ring between the stationary bearing surface and the rotating bearing surface.
  • This measure provides freedom in choosing the materials that form the bearing surfaces.
  • An intermediate ring on which bearing surfaces can be produced, for example, from polytetrafluoroethylene, polyether ether ketone or similar aterials. Similar materials in contact bearing surfaces can be bypassed by the intermediate ring, so that there are better storage properties.
  • An intermediate ring also protects the bearing surfaces when using an abrasive fluid.
  • the cleanability of the cleaner can be improved by the spray body is releasably attached to the shaft.
  • the parts can be easily disassembled and subsequently cleaned more thoroughly than in the assembled state.
  • Another way to increase the cleanability and simplify is to form according to a development of an outlet on the spray body so that the exiting through the outlet fluid is rotated and held. As a result of this design, fewer components are required inside the cleaner. The geometry becomes simpler, so that a waiver of difficult to clean parts and cavity sections is possible.
  • a simple design of the outlet in order to achieve a very good drive effect and to obtain good throughput and good spray pattern of the cleaning liquid is an axially extending slot which passes through the wall of the spray body tilted against a radial direction.
  • Fig. 1 Side view of a rotating cleaner
  • Fig. 2 longitudinal section through the rotating cleaner
  • Fig. 3 Longitudinal section through the housing, shaft, guide sleeve and intermediate ring in exploded view.
  • a rotating cleaner 1 is shown in Fig. 1.
  • the rotating cleaner 1 has a housing 2 and a rotatable spray body 3.
  • the spray body 3 has a neck 4, in which a shaft 5 is received. With a clamp 6, a releasable connection between the neck 4 and shaft 5 is effected.
  • the housing 2 of the cleaner 1 has pin holes 7. These make it possible to detachably connect the cleaner 1 to a supply line (not shown) for fluids, for example the cleaning fluid of a Cteaning-fn-Piace process, for example by means of a pin or a second bracket.
  • At least one outlet for a cleaning fluid is provided on the spray body 3.
  • the outlet is designed as a slot 8, which runs ilves the axial direction A.
  • the rotating cleaner 1 is shown in Fig. 2 in section along the axis of rotation D.
  • the axis of rotation D defines at the same time the axial direction A.
  • the housing 2 of the rotating cleaner 1 has an inlet 9, through which, especially during a cleaning operation, predominantly liquid cleaning agent can enter the cavity 10 in the interior of the cleaner 1.
  • the spray body 3 is also hollow and has an interior space 11, Preferably, the inner surface of the spray body 3 is smooth and pierced only by at least one in the example as a slot 8 shaped outlet. Cavity 10 and interior 1 are fluidly connected to each other by means of a shaft 5 passing through the shaft interior 12.
  • the shaft 5 has a bearing section 13. This is accommodated in a space which is formed between the housing 2 and a guide sleeve 14.
  • the guide sleeve 14 has a guide portion 15, which may be cylindrically shaped and engages in the matching cylindrically shaped shaft interior 12.
  • the guide section 15 is in particular designed to effect a radial guidance of the shaft 5 in the housing and thus to contribute to a stable rotation of the shaft 5 about the axis of rotation D.
  • the movement of the guide sleeve 1 along the axis of rotation D in the direction of the inlet 9 is limited by a projection 16. This is shaped so that on the one hand causes this limitation.
  • the guide sleeve 14 is through the inlet 9 therethrough slidably over the projection 16 and locked in the position shown with a slight play in the axial direction A.
  • the gap between the housing 2 and guide sleeve 14, in which the bearing portion 13 of the shaft 5 is received, and in which an intermediate ring 17 may be provided, is filled with fluid, when in the operation of the cleaner, the assembly of the spray body 3 and shaft 5 in rotation is offset.
  • the fluid enters this spa through at least one supply port 18.
  • the gap may have, as a gap portion, an axial gap 19 surrounding the cylindrical portion of the shaft 5. From this axial gap 19, the fluid then flows between the actual Lagerfiambaen and exits through at least one outlet opening 20 from the gap and the housing 2 of the cleaner 1.
  • the slot-shaped outlet in the spray body 3 passes through the wall 21.
  • the slot 8 is formed in the wall 21 so that the spray body is set in rotation by the leakage of the pressurized fluid, for example a cleaning liquid suitable for hygienic processes. This is achieved, for example, by introducing the slot 8 displaced by an offset V against the axis of rotation D into the wall.
  • the slot 8 passes through the wall 21 tilted against the radial direction R.
  • Fig. 3 are in a sectioned and disassembled view of housing 2, spray body 3, shaft 5 and the not necessarily necessary but advantageous intermediate ring 17 are shown.
  • the order of representation of the components in Fig. 3 corresponds to the order in which these components are mounted.
  • the intermediate ring 17 is inserted into the cavity 10 of the housing 2. This is followed by the shaft 5 and finally the guide sleeve 14. Once this is pushed over the projection 16 away and is limited by this in the mobility in the axial direction A, the assembly of the components shown in Fig. 3 is completed.
  • a stationary bearing surface is formed in the housing 2 of the rotating cleaner . It is conically shaped, its geometry is created by rotation of a generatrix E1 about the axis of rotation D.
  • the generatrix E1 forms an angle W1 with this axis of rotation which is in the range 35 degrees to 45 degrees, advantageously in the range 40 degrees to 45 degrees.
  • This Angle range is favorable for absorbing the axial and radial forces that occur during operation of the sliding bearing.
  • intermediate ring 17 may be conically shaped.
  • a generatrix E2 forms an angle W2 with the axis of rotation D.
  • This angle W2 advantageously corresponds to the angle W1 or deviates from it only by a few degrees in order to avoid material stress.
  • Soft materials allow a higher deviation than hard materials.
  • the material has to be selected with regard to the application factor, for example health-compatible in the food sector.
  • it must be able to form the part of a sliding bearing, since the inner and outer conical surfaces of the intermediate ring are in sliding contact with the actual bearing surfaces.
  • a material that meets these requirements is, for example, polytetrafluoroethylene (PTFE).
  • the bearing portion 13 of the basic cylindrical shaft 5 also has a conical shape.
  • a generating E3 of this cone makes a wink! W3 with the axis of rotation D.
  • this angle W3 corresponds to the angle W1 in the context of production facilities.
  • An outer surface of the conical bearing portion 13 forms the rotating bearing surface 23 of the sliding bearing.
  • shaft holes 24 are provided, which are penetrated by the bracket 6 in the assembled state of the rotating cleaner 1.
  • the shank 5 can be made of polyetheretherketone (PEEK) or a plastic comparable in comparison to the mechanical and hygienic requirements as well as the suitability for a slide bearing. This makes it possible to dispense with the intermediate ring 17.
  • the guide sleeve 14 serves to stabilize the shaft 5 in the axial direction and to improve the rotation.
  • the rotation is improved by the guide section 15 located at an end of the guide sleeve facing the shaft 5, which is cylindrically shaped and dips into the shaft interior 12. By sliding contact between the shaft 5 and guide sleeve, the rotation is improved.
  • a sleeve cone 25 adjoins the guide section on the side facing away from the shaft 5.
  • the sleeve cone 25 has a conical surface whose shape can be described by a generator E4.
  • the generator E4 forms an angle W4 with the axis of rotation D.
  • This angle W4 corresponds advantageously in the producible frame the angles W1, W2 and W3.
  • the sleeve cone stabilizes the rotation of the shaft 5.
  • the sleeve cone 25 absorbs these forces and thus stabilizes the shaft 5 also in the axial direction.
