Quick automatic cleaning agitating unit for system of reloading

Technical Field

The utility model relates to a wash technical field, concretely relates to quick automatic cleaning agitating unit for system of reloading.

Background

In production and application, the situation that products with different colors or products with different performance requirements need to be processed in the same process often occurs, raw materials need to be replaced if the products have different colors or different performances, and for some raw materials which need to be stirred and used at the same time, a container for containing the raw materials and a stirring structure for stirring the raw materials need to be cleaned while the raw materials are replaced, so that the replaced raw materials are not influenced by the raw materials before replacement; in order to ensure the cleanliness of cleaning, a special cleaning device is generally adopted to clean the container and the stirring structure in the prior art, but the stirring structure needs to be lifted out of the container and transferred to the special cleaning device for cleaning in the cleaning mode, so that on one hand, the cleaning process is time-consuming, and on the other hand, when the stirring structure is transferred, raw materials remained on the stirring structure are easy to drip on the ground, and the ground pollution is caused.

Taking the replacement of automobile spraying paint as an example, the color varieties of the automobile paint are developed from more than 50 types at first to more than 600 types at present, in order to facilitate the rapid replacement of different paints, the existing automobile coating production line is generally provided with a rapid color changing paint supplying system, the rapid color changing paint supplying system generally comprises a stirring barrel, a stirring assembly, a cleaning device, a feeding pump station, a special pipeline and a gun station assembly, and the stirring assembly is arranged on a barrel cover of the stirring barrel; when carrying out normal spraying, belt cleaning device does not participate in work, and the stirring subassembly inserts and constantly stirs the coating of splendid attire in the paint agitator, and the coating of stirring is by feed pump station through the tube pumping to rifle station subassembly and carry out the spraying. When the coating needs to be replaced, the stirring assembly (with the stirring blade and the stirring shaft) needs to be transferred to a cleaning device, and the stirring assembly is washed through a nozzle arranged in the cleaning device; in the process of transferring the stirring assembly, paint originally attached to the stirring assembly usually drips to cause ground pollution; and then usually need to drop into a large amount of cleaning solvent earlier to the washing of agitator, then clean the washing to the agitator inner wall through artifical with industrial non-woven fabrics, and the cleaning solvent who adopts among the cleaning process usually belongs to the toxicant of xylol class, and this material volatilizees easily, and the in-process of artifical washing agitator brings health hazard for operating personnel very easily.

In order to solve the above problems, in the prior art, there is a technical solution for improving an agitator, which is exemplified by a patent disclosed in chinese patent publication No. CN209530649U, in which a plurality of nozzles are installed in the agitator, the plurality of nozzles are distributed annularly along an inner wall of a tank body, the agitator is connected with a drain pipe, the drain pipe is communicated with a pump body, when a raw material needs to be replaced, a stirring assembly does not need to be lifted out of the agitator, but the stirring assembly is directly sprayed through the nozzles, because the nozzles are distributed annularly, a cleaning solvent sprayed from the nozzles can also be sprayed onto an inner wall of the opposite agitator, thereby achieving automatic cleaning of the agitator and the stirring assembly, and a waste liquid after cleaning is extracted from the drain pipe through the pump body. Although the mode does not need to transfer the stirring assembly, the cleaning efficiency is improved, but the cleaning effect is poor, for example, the problem that the inner wall of the stirring barrel is not completely cleaned often exists.
