Description

Electrostatic precipitator

technical field

The utility model relates to a dust removal device, in particular to an electrostatic dust removal device suitable for surface cleaning treatment of workpieces before entering various spray booths for spraying.

Background technique

As we all know, plastic workpieces generate static electricity due to friction during injection molding and transportation, and absorb a large amount of dust on their surfaces. If it is not cleaned before spraying, spraying on its surface will cause unevenness, streaks, spots, pitting, and weak adhesion of the workpiece, making the aesthetics of the workpiece poor and the use value reduced. The disadvantages of vacuum-coated workpieces are more obvious. Therefore, before the workpiece enters the spray booth for spraying, the dust attached to the surface of the workpiece due to static electricity must be removed.

In order to effectively remove the dust adsorbed on the surface of the workpiece, compressed air is usually used to blow the accumulated dust away from the surface of the workpiece. However, there will still be some dust floating in the workshop, causing air pollution, and then falling back to the surface of the workpiece, affecting the dust removal effect.

Therefore, it is necessary to provide an improved dust removal device to overcome the above-mentioned defects.

Compared with the prior art, in the electrostatic precipitator of the present utility model, most of the dust blown off by the dedusting nozzle is sucked into the dust collecting cabinet along with the air flow, and the dust which is not easy to be sucked into the dust collecting cabinet at the corners is sucked into the dust collecting cabinet by the surrounding water tanks. Adsorption prevents the dust on the corners from forming secondary pollution and improves the dust removal effect. In addition, since the side wall of the dust removal chamber is equipped with an electrostatic generator, it can effectively eliminate the static electricity generated by the friction between the workpiece and the surrounding medium due to rotation, reduce the adsorption capacity of dust, and further improve the dust removal effect.
