Gas-solid mixer for coating device

Abstract

The invention provides a gas-solid mixer for a coating device, and belongs to the technical field of coating devices. The gas-solid mixer solves the technical problems that in the prior art, the uniformity of powder entering the coating device cannot be guaranteed, and the quality of coating is affected. The gas-solid mixer comprises a powder feed chamber which is connected with a powder feed mechanism and internally provided with a cavity. One end of the powder feed chamber is provided with a feed port, the other end of the powder feed chamber is detachably connected with a mixing chamber, and the side wall of the powder feed chamber is provided with a first gas inlet. The mixing chamber is internally provided with a cavity, the side wall of the mixing chamber is provided with a discharge port, and the other end of the mixing chamber is connected with a pressurizing assembly internally provided with a cavity. The side wall of the pressurizing assembly is provided with a second gas inlet, and the cavity inside the pressurizing assembly is communicated with the cavity inside the mixing chamber. According to the gas-solid mixer, full gas-solid mixing can be carried out on the powder of the coating device in advance, and therefore the quality of coating can be improved.

Description

technical field [0001] The invention belongs to the technical field of spraying equipment, and relates to a gas-solid mixer used for 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 pip...

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
