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 tank cleaner has a first housing part, which can be connected to a supply line, a second housing part rotatable against the first housing part, an output shaft which is rotatably received in the first housing part and connected to the second housing part, and with one directly or indirectly to the output shaft connected drive.
- the reliability of the tank cleaner is increased by improved screw connections. Unintentional loosening of the connection between the second housing part and the output shaft during the closing of the connection between the tank cleaner and the supply line is prevented in that the first housing part has a first thread for connecting to the supply line and the output shaft has a second thread for connecting to the second housing part and a direction of rotation of the first thread and a direction of rotation of the second thread are the same.
- the reliability is further increased in that a securing element is in engagement with the output shaft and the second housing part.
- the securing element comprises a threaded pin with a conical head and the conical head is in engagement with the output shaft.
- a retaining plate is arranged on the second housing part to cover the threaded pin. This additionally increases the security of the connection. This is further increased in that a screw penetrates the retaining plate and is received in the second housing part. The effect is further increased in that a wedge locking washer is arranged between a head of the screw and the holding plate.
- the mountability is increased in that the second housing part has a first opening and a second, second opening opposite the first opening, the surface normals of which are oriented perpendicular to a longitudinal axis of the tank cleaner. This is more pronounced in an embodiment in which the securing element is accessible through one of the first opening and the second opening.
- the reliability is more effective in a tank cleaner, which is further developed in that a shaft is rotatably received in the second housing part, on which a nozzle carrier is arranged.
- the drive comprises a stator and a turbine wheel, and stator and turbine wheel by means of a coupling section are removably arranged.
- the screw connection of the supply line and tank cleaner is separated, so that the configuration of the screw connection between the output shaft and the second housing part that is secured against loosening is of particular advantage.
- Fig. 2 Section through part of the tank cleaner.
- a tank cleaner 1 is shown in longitudinal section. It has a first 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.
- a one-part or multi-part second housing part 4 is rotatably arranged on an end of the first housing part 2 facing away from the coupling section 3.
- the axis of rotation of the rotational movement of the second housing part 4 can coincide with a longitudinal axis L of the stationary housing part 2.
- a nozzle carrier 5 On the second housing part 4 there is a nozzle carrier 5 which is rotatable about a second axis of rotation D. At least one nozzle 6 is connected to the nozzle carrier 5, and its shape 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 second 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 second housing part 4 is designed so that a force is generated in the cavity 13 by the pressurized fluid that compensates for a force caused by the Fluid acting on the nozzle carrier 5 is generated and acts on the shaft 10.
- the second housing part 4 has a first opening 14 and a second opening 15 arranged on a side facing away from the first opening.
- the openings span planes whose surface normals are parallel to one another and approximately perpendicular to the longitudinal axis L.
- 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.
- the shaft receptacle 11 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 allows
- a drive is provided in the first 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 comprises a stationary stator 18 with at least one guide vane 19 and, downstream, a rotatably arranged turbine wheel 20 with at least one T urbine 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 second housing part 4 and causes the second 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.
- connection between the supply line and tank cleaner 1 is designed as a screw connection, which is why the coupling section 3 comprises a first thread 26 which is brought into engagement with a mating thread on the supply line when the tank cleaner 1 is installed on the supply line.
- the mechanical connection of the output shaft 23 to the second housing part 4 comprises a screw connection in which a second thread 27 provided on the output shaft 23 is brought into engagement with a mating thread on the second housing part 4.
- the direction of rotation or the direction of rotation of the screw connection results from the alignment of a pitch of a thread turn of a thread.
- the direction of rotation when tightening the screw connection can be by turning one of the parts to be connected clockwise or counterclockwise or left or right.
- Closing the connection between the supply line and the tank cleaner 1 should not lead to an unintentional loosening of the connection between the second housing part 4 and the output shaft 23.
- Closing the connection between the supply line and tank cleaner 1 is necessary, for example, when mounting the tank cleaner 1 on the supply line. This can be the initial assembly or assembly after maintenance of the tank cleaner 1. If the drive has, for example, stator 18 and turbine wheel 20 and these are to be removed through the coupling section 3, the tank cleaner 1 must be disconnected from the supply line and again after the change be mounted on it.
- the connection between the second housing part 4 and output shaft 23 should not be unintentionally loosened or released. The risk of unintentional loosening is considerably reduced in that the first thread 26 and the second thread 27 are designed with the same direction of rotation.
- a securing element is provided which is in engagement with the output shaft 23 and the second housing part 4 and thus additionally secures the screw connection between the second housing part 4 and the output shaft 23 against unintentional loosening.
- FIG. 2 A particularly structurally simple, inexpensive and reliable securing of the screw connection with the aid of a securing element is shown in the detailed view in FIG. 2.
- the securing element comprises a threaded pin 28 with a conical head 29.
- the conical head 29 is brought into engagement with a receptacle 30 which is provided on the output shaft 23.
- the holding plate 31 can be fastened with a screw 32 which penetrates the holding plate 31 and is received in the second housing part 4.
- An additional securing is effected in that a wedge locking washer 33 is arranged between a head of the screw 32 and the retaining plate 31.
- securing element and other securing components such as threaded pin 28, retaining plate 31, screw 32 and wedge locking washer 33 can be removed through one of the openings 14 and 15.
