Description

Technical Field

[0001] The utility model relates to the technical field of powder spraying chambers, in particular to a powder spraying chamber with automatic cleaning of the powder chamber. Background Art

[0002] The high-temperature spraying process is a surface processing method that atomizes the molten spraying material through a high-speed air flow and sprays it on the surface of the purified and roughened parts to form a sprayed coating. In an automated workshop, the workpieces are carried on a suspended assembly line and then circulated. The processing process is roughly as follows: suspended assembly line mounting → degreasing → water washing → phosphatizing → pure water washing → drying → powder spraying → drying → worker blanking.

[0003] In the existing spraying process, the powder spraying chamber is a device that can automatically spray powder on the surface of the passing workpieces. The powder spraying chamber sprays powder through multiple groups of nozzles. Therefore, a large amount of powder will fall to the bottom of the powder spraying chamber. These powders have the value of being reused. Traditional technical workers will use an air gun and a vacuum cleaner in cooperation for collection. This cleaning efficiency is relatively low. Therefore, it is necessary to design a powder spraying chamber with automatic cleaning of the powder chamber to solve the above problems. Summary of the Utility Model
