[0002] Zinc oxide is an oxide of zinc, which is insoluble in water but soluble in acid and strong alkali. Zinc oxide is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints, ointments, adhesives, foods, batteries, flame retardants and other products. Zinc oxide will produce a lot of dust during production. If it is not treated, it will cause air pollution and waste of zinc oxide. Therefore, it is necessary to collect the dust during production.

[0010] Furthermore, a ventilation pipe is installed on the top of the fixing frame, one end of the ventilation pipe is connected to a fan, and two branch pipes penetrating the fixing frame are fixedly connected to the bottom.

[0011] Furthermore, the fan is installed on the top of the collecting box, and the branch pipe is connected to the connecting pipe through a rotating joint.

[0012] The advantages of the utility model compared with the existing technology are: the motor of the utility model drives the driving gear to drive the driven gear and the connecting pipe to rotate, and the connecting pipe drives the filter screen to rotate through the mounting ring, and then the zinc oxide dust particles attached to the surface of the filter screen can be brushed off by the cleaning brush, and the surface of the filter screen can be cleaned in all directions by the cleaning brush, so the cleaning effect is good and the practicability is strong.
