Description
Technical Field
The invention relates to the technical field of electrostatic spraying, in particular to die casting electrostatic spraying equipment with recyclable spraying powder.
Background
The electrostatic spraying of aluminum alloy die castings is a common aluminum alloy surface treatment process, and is mainly characterized in that charged powder paint is sprayed on the surface of a metal product (such as aluminum alloy die castings), and then the powder after baking can be stably attached to the surface of the aluminum alloy die castings by a high-temperature baking and shaping method, so that Gao Wenpen powder is also called. The surface treatment process increases the acid and alkali resistance and the metal corrosion resistance of the aluminum alloy die casting, thereby prolonging the service life of the product. Principle of electrostatic spraying of aluminum alloy die castings: by arranging two equal and opposite charges on both sides of the metal opposite each other, they attract each other and hold the powder particles on the metal surface.
The existing electrostatic spraying equipment generally presses the objective table against the bottom of the spraying box, so that the phenomenon that powder is scattered everywhere in the spraying process is avoided, and the powder attached to the inside of the spraying box is blown up by the fan blades, so that the powder in the spraying box can be filtered and recycled through the air exhauster; however, in this technology, the filter device for treating the powder spray is usually fixedly installed inside the powder collecting box, and during the use of the filter plate, the surface and the inside of the filter plate are blocked by the powder spray which is hardened by backlog after long-term use, and although the existing cleaning brush can clean the powder spray on the surface of the filter plate, the powder spray inside the filter plate is not easy to clean, the suction and filtration effects are affected for a long time, and the filter device needs to be replaced integrally, which is very troublesome.
