Efficient zinc oxide filtering and collecting device

Abstract

The invention relates to the technical field of zinc oxide production equipment, and particularly discloses an efficient zinc oxide filtering and collecting device. The efficient zinc oxide filtering and collecting device comprises a collecting box, a collecting hopper, a feeding system and a negative pressure air inducing pipe, a partition plate is arranged at the upper end of the collecting box, a plurality of filter bag assemblies extending into the lower end of the collecting box are installed on the partition plate, a dust striking plate is arranged under the partition plate, through holes corresponding to the filter bag assemblies are formed in the dust striking plate, and a power assembly used for driving the dust striking plate to rise and fall instantly is further arranged on the partition plate; through the arrangement of the dust striking plate and a compressed air cleaning system, when the dust striking plate falls down and excites dust attached to a filter cloth bag, the excited dust is blown into the collecting hopper by blowing compressed air, so that the excited dust can be effectively prevented from being attached to the filter cloth bag for the second time, the filter cloth bag can be quickly and effectively cleaned and dredged, the whole efficient zinc oxide filtering and collecting device is novel in structural arrangement, excellent in anti-blocking effect and high in practicability.

Description

technical field [0001] The invention relates to the technical field of zinc oxide production equipment, and specifically discloses a high-efficiency filtration and collection device for zinc oxide. Background technique [0002] In the dry preparation process of zinc oxide, the zinc ore is generally heated to form a molten liquid, and the solution is continuously evaporated to form zinc vapor, which is oxidized in contact with the incoming air, then cooled, and finally passed through a filter bag. Zinc oxide in the air is deposited and collected. However, in actual production, zinc oxide dust is easy to adhere to the filter bag. During use, as the intake time increases, due to the accumulation of zinc oxide dust on the filter bag, the filtering effect of the filter bag will continue to decrease until it becomes clogged. . [0003] The invention with the application number 2019111890550 discloses a dust recovery device for zinc oxide production, including an intake pipe, a d...

AI Technical Summary

Problems solved by technology

The above-mentioned air pulsation zinc oxide collection device passes compressed air into the filter bag through the compressed air pulse introduction mechanism, which can wash away the zinc oxide dust attached to the filter bag. However, when the compressed air is set too large, it is mainly because when the compressed air is set When it is too large, the zinc oxide dust deposited at the lower end of the collection box will be blown up, and the compressed air with moderate strength has a general effect on washing the zinc oxide dust attached to the filter cloth, so the anti-clogging cleaning effect on the filter cloth is also general
