Definitions
- the invention relates to a device for cleaning objects contaminated with paint and lacquer, in particular paint spray guns, according to the preamble of claim 1, and to a method for cleaning objects contaminated with paint and lacquer, in particular
- Spray guns are very important to clean as thoroughly as possible, because deposits inside the spray guns can clog the flow passages and flow nozzles, but also to an uneven spray cone when they are actuated. For this reason, in professional painting technology, after each paint application, care must be taken to thoroughly clean the paint or spray gun used. In the same way, the facilities involved in the printing process must always be cleaned thoroughly in printing shops, so that there is no deterioration in the optical print quality or an increased amount of rejects. People who come into constant or frequent contact with solvents often suffer from occupational diseases, especially skin diseases, which often lead to disability. At the same time, thorough cleaning of items contaminated with paint and lacquer can only be achieved with a considerable amount of time, so that the productivity of an employee who is frequently entrusted with cleaning tasks is very low.
- the known cleaning liquids in the form of halogenated organic solvents are not only harmful to health but also to the environment. Improper disposal of these solvents and accidental escape of these volatile substances can cause great damage to the environment.

This measure allows the cleaning effect to be increased further, because complex-shaped objects, such as paint spray guns, rotate in the best possible way from the limited number of cleaning nozzles in the device can be achieved.
- Another advantage of the rotatable attachment of the object or objects to be cleaned is that an object to be cleaned can be partially dried by very rapid rotation, ie by spinning movements.
- a receptacle for objects to be cleaned preferably a hollow cylindrical receptacle, with passage openings for cleaning liquid in the walls can be used in the housing.
- the insertion of a receptacle has the great advantage that the possible field of application of the device is expanded.
- textiles to be cleaned For example, in printing houses, soiled wipes have to be disposed of as special waste.
- a receptacle comparable to a washing drum, into the cleaning device, these objects can also be cleaned to the extent that they are either completely reusable or at least no longer have to be disposed of separately as special waste.
- the receptacle can preferably be rotated in the cleaning device. As a result, the cleaning effect is further increased and the time required for adequate cleaning can be reduced. The associated energy savings as well as the associated time advantage have already been discussed above.
- the cleaning device has a collecting trough for receiving and specifically removing the cleaning liquid.
- a collecting trough separates the area of the device in which the cleaning process takes place from the other devices such as pumps, valves, the ultrasonic generator, but also Internals for the recirculation of the cleaning liquid.
- the cleaning nozzles can preferably either emit a cleaning liquid or else air at a high pressure.
- the advantage of this preferred, additional feature lies in the fact that various complex cleaning programs can be carried out with the device according to the invention, wherein the cleaning steps can be followed by a drying cycle using the cleaning liquid.
- certain objects to be cleaned such as spray guns, can be blown through with compressed air after the wet cleaning step, as a result of which the cleaning liquid located inside the spray gun is blown out of the spray gun as completely as possible.
