Description

Technical Field

[0001] The utility model relates to the technical field of dust collection, in particular to a zinc oxide dust collection device for zinc oxide production. Background Art

[0002] Zinc oxide powder is a white or slightly yellow powder. It is an oxide of zinc. It is insoluble in water but soluble in acid and strong alkali. It is also a very common chemical additive. In the production process of zinc oxide powder, the main raw material is zinc ore. Zinc oxide ore is generally used as the raw material. Before use, the zinc ore needs to be crushed, ground and other treatments to obtain ore particles suitable for the production of zinc oxide powder.

[0003] For example, the Chinese patent: "A zinc oxide dust collection device for zinc oxide production" with publication number CN208516956U, the technical solution disclosed in this patent is as follows: This utility model discloses a zinc oxide dust collection device for zinc oxide production, including a first base, a motor and a filter cloth, a fixed connecting plate is installed and connected above the inner wall of the device body, and an automatic telescopic rod is arranged at the inner top of the fixed connecting plate, the motor is arranged at the top left position of the device body, and the top of the motor is connected to the rotating disk through a conveyor belt, and the top of the movable air duct is connected with a suction port, the filter cloth is arranged in the middle position between the automatic telescopic rod and the automatic telescopic rod, and an adsorption block is installed at the top of the automatic telescopic rod. In the process of collecting dust, the zinc oxide dust collection device for zinc oxide production can move the absorption angle back and forth, which is convenient for large-scale absorption work during the movement.

[0004] However, in actual use, the automatic telescopic rod needs to be retracted to push and scrape the zinc oxide powder on the filter cloth. Whenever the zinc oxide powder accumulates on the filter cloth, the scraping needs to be performed, which is inefficient and inconvenient to automatically scrape the accumulated zinc oxide powder by rotating the scraper.
