Powder supplying center capable of being automatically cleaned

Abstract

The invention discloses a powder supplying center capable of being automatically cleaned. The powder supplying center capable of being automatically cleaned comprises two parts, namely, pressure maintaining housings and powder barrels, wherein the upper pressure maintaining housing and the lower pressure maintaining housing are hinged together; the upper powder barrel and the lower powder barrel are correspondingly mounted into the upper pressure maintaining housing and the lower pressure maintaining housing in a suspension manner; the pressure maintaining housings and the powder barrels adopting the abovementioned structures are conveniently opened, and thus the inner parts of the powder barrels can be conveniently repaired and cleaned. The upper powder barrel and the lower powder barrelare manufactured through fluidizing boards, and the fluidizing boards of the upper powder barrel are more than the fluidizing boards of the lower powder barrel in number; the arrangement of the fluidizing boards is simplified through the abovementioned structure, and thus the structure of the power supplying center is simplified, the convenience of mounting is improved, and the fluidizing effect is good. According to the powder supplying center capable of being automatically cleaned, the pressure in the pressure maintaining housings is kept at the set value all the time, so that the constant pressure power supplying of the powder barrels is realized; in addition, the powder is fluidized and pressurized and discharged by feeding air, so that the dust content per unit volume is increased during powder discharging; and air is blown to sweep to realize the automatic cleaning.

Description

technical field [0001] The invention relates to an automatic cleaning powder supply center. Background technique [0002] Electrostatic powder spraying is a metal surface anti-corrosion decoration process. Compared with the traditional paint finishing process, electrostatic powder spraying has the advantages of easy automatic production, good surface spraying quality, economy and environmental protection, so it is widely used in industrial production. [0003] Among them, the powder supply center is a commonly used equipment in electrostatic powder spraying. It includes a powder bucket for containing powder. The powder bucket is a closed cylindrical structure. The powder bucket is connected with a powder tube whose end is inserted into the powder bucket. The powder pipe is connected to the powder suction port of the powder pump, and the powder outlet of the powder pump is connected to the spray gun. When in use, the powder pump sucks the powder from the powder pipe inserted ...

AI Technical Summary

Problems solved by technology

When there are many spray guns installed on the powder barrel, it is necessary to clean the powder tubes of the powder gun one by one. This process is cumbersome, takes a long time, and has a low degree of automation. At the same time, cleaning the powder barrels outside is easy to cause pollution to the external environment.

[0004] To solve this problem, the applicant applied for a patent on August 17, 2015, entitled: Powder Supply Center that can be cleaned automatically. The application publication number of this application is: CN104984845 A, and the application publication date is October 2015. On the 21st, the powder bucket and the pressure holding shell in the powder supply center of this structure are integrally formed, which is inconvenient to open the powder bucket, so it is not convenient to clean the inside of the powder bucket

In addition, the structure of the air inlet chamber and the fluidized plate in this patent is complex, which is not conducive to maintenance and disassembly
