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.
  • US Pat. No. 8137481 B2 shows a generic cleaner.
  • This document presents a cleaner that can be connected to the end of a supply line which can be introduced into a container, for example through an opening in the upper region of the container.
  • a cleaning agent is fed to the cleaner through the feed 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 comprehensive wetting.
  • the shape of the openings and the rotation of the rotatable 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 according to US 8137481 B2 meets the requirements of the 3A standard. These specify a hygienic design which, according to FIG. 3A, requires that the cleaning device must be able to be dismantled and cleaned and must not include any inaccessible and therefore not to be cleaned spaces, for example screw connections in threaded blind holes.
  • the cleaning device according to US Pat. No. 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. For assembly, the rod is inserted into part 2 until holes 17 and through hole 12 are aligned. A coupling means 6 is then inserted through the holes 17 and 12.
  • the components are assembled in a container by an operator.
  • the operator must now align the components with one another with one hand and insert the coupling means through the holes and with the other hand. This is difficult because as soon as the rod rotates, the holes and no longer align with each other and the assembly fails.
  • a cleaning device is to be specified which meets the requirements according to FIG. 3A and enables simple construction and simple assembly.
  • the invention achieves the above-mentioned object by a cleaning device according to claim 1.
  • the invention proposes a cleaning device of the type mentioned at the outset, comprising: a base body which can be coupled to a supply line for supplying a cleaning agent, a rotating body rotatably mounted on the base body about an axis of rotation, a support body with a first end section and a second in Direction of the axis of rotation A spaced end portion, wherein the first end portion with the base body and the second end portion can be coupled to the rotating body such that the rotating body is rotatably received in the coupled state between the base body and the support body, wherein the cleaning device further comprises a coupling means, which is set up to lock the support body in the coupled state relative to the base body.
  • 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 and the securing 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 use of screw connections and the like is advantageously dispensed with in the cleaning device, so that the 3A requirements are met.
  • the coupling means is preferably set up to couple the base body in the coupled and locked state to the supply line for supplying cleaning agent.
  • the base body and the support body are already coupled to one another and take up the rotating body between them before the coupling means fixes or locks the support body in the coupled state relative to the base body and couples the cleaning device to a supply line or a container. 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 fastening the cleaning device to the cleaning agent inlet, since these are already in the coupled state.
  • the coupling means can be releasably brought into engagement with the base body in a form-fitting manner, in order to lock the support body in the coupled state relative to the base body.
  • a releasable form-fitting connection can be cleaned in a simple manner and thus meets the 3A requirements.

  • the base body and the support body are thus preassembled and form a receptacle for the rotating body.
  • This coupled state is achieved independently of the coupling means.
  • the coupling means can preferably 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 into the first position.
  • the coupled state is established by the coupling means of the support body and the base body locked or secured so that the base body and the support body are not releasably coupled to one another as long as the coupling means is in engagement with the base body.

  • a metallic material such as stainless steel has good chemical resistance and is wear-resistant.
  • the combination of a polymer and in particular polytetrafluoroethylene (PTFE) bearing ring and a supporting body or rotating body made of steel prevents the components from seizing to one another and reduces the so-called slip-stick effect.
