Description

Technical Field

[0001] The utility model belongs to the technical field of electrostatic spraying, and more specifically, it particularly relates to a powder electrostatic spraying conveying device. Background Art

[0002] Powder electrostatic spraying is a surface treatment technology that uses electrostatic force to evenly spray powder coatings on the surface of objects. The conveying device plays a crucial role in the process of powder electrostatic spraying. Its performance directly affects the conveying efficiency, uniformity, and stability of the powder coatings, and thus affects the quality and appearance of the coating.

[0003] In the prior art, the authorized publication number "CN218308794U" discloses a "device for an electrostatic spraying booth capable of recovering powder"; it includes a powder spraying booth, a cyclone separator, a first powder conveying pump, a powder collecting bucket, a second powder conveying pump, and a shaker screen. An electrostatic spraying machine is installed on the powder spraying booth, a blowing mushroom head module is laid on the inner bottom of the powder spraying booth, and a dust collecting hood is installed on the inner wall of the powder spraying booth. For the device for the electrostatic spraying booth capable of recovering powder, the powder that is not adsorbed by the workpiece falls to the bottom of the powder spraying booth. After the powder is blown up by the blowing mushroom head module, it is sucked into the cyclone separator for primary recovery along with the air flow. Under the action of the cyclone, the powder is separated from the air. The separated powder is pumped into the shaker screen and can be recycled back to the powder supply bucket after being sieved and filtered. It has the characteristics of quickly recovering dust, quickly separating air and dust, and quickly reusing the dust. The structure is simple, it can operate continuously and handle a large amount of dust, and the working efficiency is high.

[0004] The above-mentioned "device for an electrostatic spraying booth capable of recovering powder" still has some disadvantages. For example, during the process of existing powder electrostatic spraying, the powder coatings in the powder supply bucket are uneven, which will lead to unstable supply of powder during spraying, and further cause uneven coating thickness, which will affect the appearance quality of the product. At the same time, the coatings accumulated in the powder supply bucket will adhere to the inner wall, and the powder adhering to the inner wall will gradually accumulate to form lumps or agglomerates. These lumps may block the conveying pipeline, resulting in the powder being unable to be normally conveyed to the spray gun.

[0005] Therefore, a powder electrostatic spraying conveying device is proposed here to solve the above-mentioned problems. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a powder electrostatic spraying conveying device to solve the problem that the powder adhering to the inner wall will gradually accumulate to form lumps or agglomerates, and these lumps may block the conveying pipeline, resulting in the powder being unable to be normally conveyed to the spray gun as mentioned in the above background art.
