Self-cleaning powder supply center

Abstract

A powder feeding center capable of automatically cleaning is disclosed. A powder barrel (2) of the powder feeding center is mounted in a pressure maintaining housing (1) in a hanging way, a pressure stabilizing mouth is provided on the top of the pressure maintaining housing (1), and a powder cleaning mouth is provided at the bottom of the pressure maintaining housing (1); both of the top and the bottom of the powder barrel (2) are open, an air intake chamber (20) capable of moving up and down is disposed at the bottom of the powder barrel (2), a fluidization plate (21) is fixedly mounted on the top of the air intake chamber (20), and the air intake chamber (20) is driven by a driving device; an air intake is provided on the air intake chamber (20), and the air intake is connected to an air intake telescopic tube (25); an air intake pipe (26) is fixedly mounted on the pressure maintaining housing (1), the air intake telescopic tube (25) is connected to the air intake pipe (26), and an air intake valve (27) is mounted on the air intake pipe (26); at least one powder outlet is provided on a side wall of the powder barrel (2), and a powder outlet pipe (22) is connected to the powder outlet; and a purging device capable of moving up and down is fixedly mounted on the pressure maintaining housing (1). The air intake chamber is capable of moving up and down along with the purging device, so that a powder outlet gap is formed between the powder barrel and the air intake chamber, thereby achieving automatic cleaning of the powder barrel by means of air purging.

Description

technical field [0001] The invention relates to an electrostatic powder spraying equipment, in particular 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, th...

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.
