Definitions

  • the invention relates to a tank cleaner according to the preamble of the first claim.
  • Generic tank cleaners are used to clean tanks and containers in process systems in the beverage and food industry as well as in pharmacy and biotechnology.
  • Tank cleaners in which at least one nozzle is attached to a nozzle carrier which rotates around two axes have proven successful.
  • the two axes are approximately at a right angle to one another in order to achieve a high degree of coverage of the surface of the tank coated by the cleaning fluid emerging from the nozzle.
  • a tank cleaner can be dismantled with the aid of detachable component connections.
  • the design of the potion cleaner and maintenance are aimed at high reliability in terms of consistent cleaning performance. However, if a connection is lost during operation, this can reduce the cleaning performance.
  • the proposed tank cleaner has a stationary housing part which can be connected to a supply line, a housing part rotatable against the stationary housing part, a shaft which is rotatably arranged in the rotatable housing part, and a nozzle carrier which has a nozzle and which is connected to the shaft.
  • the reliability of the tank cleaner is significantly increased by the fact that the shaft is positively received in the nozzle carrier and a securing element is provided to ensure the form fit.
  • the form fit can be created, for example, by interlocking square or polygonal structures provided on the shaft and nozzle carrier and by a toothing. In this way, the nozzle carrier is securely connected to the shaft, making it more difficult to loosen with a subsequent deterioration in cleaning performance.
  • a key that is inexpensive to manufacture and easy to assemble is proposed, which is received with a first section in the shaft and a second section in the nozzle carrier.
  • a shaft end assigned to the nozzle carrier has a thread and that the securing element is designed as a closed nut. This is an embodiment of the mother that takes hygienic requirements into account.
  • a screw locking element is provided between the nut and nozzle carrier, for example a lock nut or the like.
  • a particularly effective embodiment of the screw locking element is to design it as a wedge locking washer.
  • Another embodiment suggests that a seal is arranged between the nut and the nozzle carrier. This prevents residues from being deposited in the gap between the nut and the nozzle carrier.
  • the secure connection comes into its own in an embodiment in which the nozzle is detachable and replaceable, because the connection remains secure even when the nozzle is changed.
  • an inexpensive interchangeable connection is when the nozzle is screwed into the nozzle carrier.
  • the cleaning performance of the tank cleaner is increased in a further development in that a flow straightener is arranged between an interior of the nozzle carrier and an outlet of the nozzle.
  • the tank cleaner is designed such that the rotatable housing part has a first opening and one on one of the first opening having remote side arranged second opening, and the shaft penetrates at least one of the first opening and the second opening. This causes a symmetrical loading of the shaft during operation when there is cleaning fluid under pressure inside the tank cleaner. This in turn improves reliability.
  • Fig. 2 Section through part of the nozzle carrier and the shaft.
  • a tank cleaner 1 is shown in longitudinal section. It has a stationary housing part 2 which has a coupling section 3 at a first end. With the aid of the correspondingly designed coupling section 3, the tank cleaner 1 can be connected to a feed line (not shown) through which the cleaning fluid can flow into the tank cleaner 1.
  • the connection can be designed, for example, as a screw connection, in which case the coupling section 3 has a thread which is brought into engagement with a mating thread on the supply line when the tank cleaner 1 is mounted on the supply line.
  • a one-part or multi-part rotatable housing part 4 is arranged at an end of the stationary housing part 2 facing away from the coupling section 3.
  • the axis of rotation of the rotational movement of the rotatable housing part 4 can coincide with a longitudinal axis L of the stationary housing part 2.
  • a nozzle carrier 5 On the rotatable housing part 4 there is a nozzle carrier 5 rotatable about a second axis of rotation D. At least one nozzle 6 is connected to the nozzle carrier 5, the shape of which forms a jet of cleaning fluid.
  • a flow straightener 9 can be arranged between an interior 7 of the nozzle carrier 5 and an outlet 8 of the nozzle 6.
  • the flow straightener 9 comprises a plurality of parallel flow channels and thereby causes a more uniform fluid flow.
  • the nozzle 6 is fastened to the nozzle carrier 5 in a detachable and exchangeable manner, for example by means of a clamp or pin connection.
  • a particularly favorable embodiment is to provide the nozzle 6 with a thread and a nozzle holder on the nozzle carrier 5 with a matching mating thread. The nozzle 6 is then screwed into the nozzle carrier 5.
  • the nozzle carrier 5 is attached to a shaft 10 which is rotatably arranged in the rotatable housing part 4.
  • the shaft 10 passes through a shaft receptacle 11 with a through hole in the rotatable housing part 4.
  • the shaft 10 is mounted in this shaft receptacle 11; an additional bearing ring can be provided in the shaft receptacle 11 for this purpose.
  • a cover disk 12 is arranged on an end of the shaft 10 facing away from the nozzle carrier 5.
  • a diameter of the cover disk 12 is dimensioned and a surface facing a cavity 13 of the rotating housing part 4 is designed so that a force is generated by the pressurized fluid in the cavity 13, which creates a balance to a force caused by the Fluid acting on the nozzle carrier 5 is generated and acts on the shaft 10.
  • the rotatable housing part 4 has a first opening 14 and a second opening 15 arranged on a side facing away from the first opening.
  • the first opening is closed by the cover disk 12, the second opening 15 by the nozzle carrier 5.
  • the shaft 10 penetrates both openings 14 and 15.
  • a first ring 16 is arranged between the cover disk 12 and an edge of the first opening 14.
  • a second ring 17 is located between an edge of the second opening 15 and the nozzle carrier 5.
  • Both rings 16 and 17 mainly act as sealing rings in order to greatly reduce the leakage of cleaning fluid from the potion cleaner 1 at these points.
  • they can be designed as bearing rings in order to support the cover disk 12 and nozzle carrier 5 in a rotatable manner.
  • the rings 16 and 17 can jointly or individually have at least one division along a circumference, which can produce a small gap. This makes it possible to compensate for expansion that occurs due to the heating of the split ring 16 and / or 17.
  • a drive is provided in the stationary housing part 2 which converts the flow energy of the cleaning fluid flowing into the tank cleaner 1 through the feed line in order to be able to cause the nozzle carrier 5 to rotate.
  • the drive advantageously includes a stationary stator 18 with at least one guide vane 19 and downstream a rotatably arranged turbine wheel 20 with at least one turbine blade 21.
  • the turbine wheel 20 is operatively connected to a transmission gear 22, which can be designed as a planetary gear.
  • the output shaft 23 of the transmission gear 22 is mechanically connected to the rotatable housing part 4 and causes the rotatable housing part to rotate about the longitudinal axis L.
  • a first bevel gear 24, which meshes with a second bevel gear 25, is arranged on the output shaft 23. This is attached to the shaft 10, which is approximately at right angles to the output shaft 23. The engagement of the bevel gears 24 and 25 causes the shaft 10 to rotate about a second axis of rotation D as soon as fluid is applied to the drive.
  • nozzle carrier 5 is shown in detail in a sectional view.
  • the shaft 10 is received in the nozzle carrier 5, the shaft 10 and nozzle carrier being set up to form a form fit that prevents the nozzle carrier 5 from rotating relative to the shaft 10.
  • a securing element is provided which ensures that the form fit is maintained.
  • the example shows a form of positive locking that is inexpensive when the parts are in the correct position and simple to assemble and maintain.
  • a feather key 26 is provided, which is received with a first section in the shaft 10 and a second section in the nozzle carrier 5. It is structurally simple to provide a groove on each of the shaft 10 and nozzle carrier 5, into which the feather key 26 dips over part of its extension.
  • An advantageously simple way of securing the form fit is created in that the shaft 10 completely penetrates the nozzle carrier 5 and emerges from a side of the nozzle carrier 5 facing away from the rotatable housing part.
  • a thread 27 is formed which is received in the securing element designed as a closed nut, in particular as a flood nut 28.
  • the securing element is advantageously secured against unplanned loosening.
  • An advantageous form of securing suggests providing a screw locking element between the cap nut 28 and the nozzle carrier 5, which prevents the cap nut 28 from loosening on the thread 27 by means of a frictional connection or a combination of frictional, non-positive and positive locking.
  • a wedge locking washer 29 has proven to be an advantageous, safe, clean and inexpensive solution for the screw locking element for practical use.
  • Shaft 10, nozzle carrier 5 and cap nut 28 are shaped in such a way that there is no metallic stop between cap nut 28 and nozzle carrier 5, but rather the metallic stop of cap nut 28 is located on wedge lock washer 29, which in turn rests in metal on nozzle carrier 5.
