Powder supply center capable of automatic clearing

Abstract

The invention discloses a powder supply center capable of automatic clearing. A powder barrel is arranged in a pressure preserved shell body in a suspension mode. A pressure stabilizing opening is formed in the top of the pressure preserved shell body. A powder clearing opening is formed in the bottom of the pressure preserved shell body. The top and the bottom of the powder barrel are open. An air inlet chamber is arranged at the bottom of the powder barrel. A fluidization plate is fixedly arranged at the top of the air inlet chamber. The air inlet chamber is driven by a driving device. An air inlet is formed in the air inlet chamber. The air inlet is connected with an air inlet telescopic pipe. An air inlet pipe is fixedly arranged on the pressure preserved shell body. The air inlet telescopic pipe is connected with the air inlet pipe which is provided with an air inlet valve. At least one powder outlet is formed in the side wall of the powder barrel and is connected with a powder outlet pipe. A blowing-sweeping device is fixedly arranged on the pressure preserved shell body. A blowing-sweeping chamber which can move up and down is arranged, the air inlet chamber can move up and down with the blowing-sweeping chamber, so that a powder outlet gap is formed between the powder barrel and the air inlet chamber, automatic clearing of the powder barrel is achieved, after powder barrel clearing is over, the powder outlet pipe can be opened and is cleared, and automatic clearing of the powder supply center is achieved by gas blowing sweeping.

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...

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.
