Definitions

  • the invention relates to a cleaning device for cleaning a container, in particular an inner wall of a container, and a method for assembling a cleaning device.
  • This document presents a cleaner which is connectable to the end of a feed line which can be introduced into a container, for example through an opening in the upper region of the container.
  • a cleaning agent is supplied to the cleaner through the supply line.
  • the cleaning device has openings through which this cleaning agent emerges and subsequently wets the inner wall of the container.
  • the openings are provided on a rotatable part of the cleaning device in order to achieve the largest possible and most comprehensive wetting. Shaping the openings and rotating the rotating part create a spray pattern on the inner wall of the container.
  • the aim is to achieve a mechanical effect in addition to dense wetting in order to achieve thorough cleaning.
  • the cleaning device after the US 8137481 B2 meets the requirements of the 3A standard. These specify a hygienic design, which according to 3A requires that the cleaning device must be able to be dismantled and cleaned and must not include rooms that are inaccessible and therefore cannot be cleaned, for example screw connections in threaded blind holes.
  • the cleaning device after the US 8137481 ensures this with the following structure:
  • the rotating part 4 of the cleaning device sits on a surface 9 of a base part 7.
  • This has a rod 8 with a through hole 12.
  • the rod 8 is received in a stationary part 2, the wall of which has holes 17 opposite one another.
  • the rod is inserted into part 2 until holes 17 and through hole 12 are aligned.
  • a coupling means 6 is inserted through the holes 17 and 12.
  • the components are assembled by an operator in a container.
  • the operator now has to orient the components to each other with one hand and insert the coupling means through the holes with the other hand. This is difficult because as soon as the rod rotates, the holes become aligned and no longer aligned with each other and the assembly fails.
  • An object of the present invention is therefore to provide an improved cleaning device.
  • an object of the present invention is to provide a cleaning device which overcomes at least one of the stated disadvantages of the prior art.
  • a cleaning device should be specified that meets the requirements of FIG. 3A and enables simple construction and easy assembly.

  • the invention includes the knowledge that the coupling of the components to one another and the fixing or locking of the components in the coupled state as well as the protection against falling apart are functionally separated by means of the coupling means.
  • the base body and the support body are already coupled to one another and accommodate the rotating body between them before the coupling means fixes or locks the support body in the coupled state relative to the base body.
  • the cleaning device advantageously dispenses with the use of screw connections and the like, so that the 3A requirements are met.
  • the coupling means is designed to couple the base body in the coupled and locked state with the supply line for supplying cleaning agent.

Consequently, during assembly, in particular in a tank, initially only the components of the cleaning device are coupled to one another and then the arrangement is attached to the cleaning agent inlet. There is no need to check the arrangement of the support body relative to the base body and the other components of the cleaning device before attaching the cleaning device to the cleaning agent inlet, since these are already in the coupled state.
  • the coupling means can be brought into positive, releasable engagement with the base body in order to lock the support body in the coupled state relative to the base body.
  • a detachable, positive connection can be easily cleaned and therefore meets the 3A requirements.

  • the base body and the support body are therefore pre-assembled and form a receptacle for the rotating body.
  • This coupled state is achieved independently of the coupling agent.
  • the coupling means can be brought into engagement with the base body in such a way that the coupling means prevents the movement of the support body from the second position back to the first position.
