Description

Technical Field

[0001] The utility model relates to the field of powder collection, and more specifically to a dust collection structure for electrostatic powder spraying on metal surfaces. Background Art

[0002] The working principle of electrostatic powder spraying is almost the same as that of general liquid coating electrostatic spraying, except that powder spraying is dispersed rather than atomized. It is a coating sprayed by an electrostatic powder spray gun, which makes the powder particles negatively charged while dispersing. The charged powder particles are affected by airflow (or other forces such as centrifugal force) and electrostatic attraction, and are coated on the grounded object to be coated, and then heated, melted and solidified into a film. In the document with publication number CN215695154U, an electrostatic powder spraying collection device is proposed, which is provided with an adjustable collection port inside the spray room, and the collection port is connected to the two-stage collection device through a collection pipe, and the axial flow fan on the collection pipe provides power, and the dust will fall into the second collection cylinder or adhere to the second filter net, and the clean air will be discharged to the outside space through the second filter net. When the electrostatic powder spraying collection device is used, the operator holds a spray gun to spray the metal surface. However, the operator holds the spray gun and stands in the spraying room to spray. Part of the spray is absorbed by the human body, which will affect the health of the sprayer. It is less safe and inconvenient to use. Utility Model Content
