Improved vertical type section bar electrostatic spraying and coating device

Abstract

The invention provides an improved vertical type section bar electrostatic spraying and coating device, and belongs to the technical field of spraying devices. The improved vertical type section bar electrostatic spraying and coating device solves the technical problems that in the prior art, power outlet is not uniform, and the spraying effect is poor. The improved vertical type section bar electrostatic spraying and coating device comprises a coating machine, a compressed air system and a spraying material storage tank, a sprayer mechanism is arranged in the coating machine, the compressed air system is connected with the sprayer mechanism, and the spraying material storage tank is connected with the sprayer mechanism through a material conveying mechanism. The improved vertical type section bar electrostatic spraying and coating device further comprises a gas-solid mixer which comprises a powder feed chamber internally provided with a cavity, a feed port is formed in one end of the powder feed chamber, the other end of the powder feed chamber is detachably connected with a mixing chamber, a first gas inlet and the like are formed in the side wall of the powder feed chamber, and the sprayer mechanism can rise and fall in the vertical direction. Full gas-solid mixing can be conducted on powder entering the coating machine in advance, large-grained powder is fully scattered into small-grained powder, and therefore spraying quality is improved.

Description

technical field [0001] The invention belongs to the technical field of spraying equipment, and relates to an improved vertical profile electrostatic spraying coating equipment. Background technique [0002] Electrostatic powder spraying technology is a new coating technology that has developed rapidly in recent years. It is characterized by energy saving, non-polluting process, simple powder, recyclable and easy automation, and the coating is beautiful, durable and durable. The new development direction of the industry. [0003] In the electrostatic powder spraying operation, it is necessary to send the powder into the spraying equipment with compressed air. The powder in the spraying equipment floats in the air and is adsorbed to the profile by static electricity. Therefore, the more uniform the powder in the spraying equipment, the better the spraying effect will be. the better. [0004] The existing technology usually sucks the powder into the pipeline with negative pre...

AI Technical Summary

Problems solved by technology

[0004] The existing technology usually sucks the powder into the pipeline with negative pressure, then fills the pipeline with compressed air, and transports the powder to the spraying equipment through the positive pressure of the compressed air. The process is relatively simple, but the powder entering the spraying equipment Uniformity cannot be guaranteed, thus affecting the quality of spraying
