Electrostatic spray coating equipment

Abstract

The invention provides electrostatic spraying coating equipment which belongs to the technical field of spraying equipment and aims at solving the technical problems of uneven powder discharging and poor spraying effect in the prior art. The electrostatic spraying coating equipment comprises a coater, a compressed air system and a spraying material storage tank, wherein the coater is internally provided with a spray nozzle mechanism, the compressed air system is connected with the spray nozzle mechanism, and the spraying material storage tank is connected with the spray nozzle mechanism by virtue of a material conveying mechanism. The electrostatic spraying coating equipment also comprises a gas-solid mixer which comprises a powder feed chamber with a cavity formed inside, wherein a material inlet 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, and a first gas inlet and the like are formed in the side wall of the powder feed chamber. By virtue of the electrostatic spraying coating equipment, powder entering the coater can be fully subjected to gas-solid mixing in advance and big-particle powder can be fully broken up to small-particle powder, so that the spraying quality is enhanced.

Description

technical field [0001] The invention belongs to the technical field of spraying equipment, and relates to an 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 pressure, then fills the pipe...

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
