Description

TECHNICAL FIELD

[0001] The utility model relates to a dust removal structure, in particular to a novel pulse dust cleaning dust removal structure. BACKGROUND

[0002] The pulse dust cleaner is a new type of high-efficiency pulse dust cleaner improved on the basis of the bag type dust collector. When cleaning dust, the pulse control instrument sequentially triggers each control valve to open the pulse valve. The compressed air in the air pocket is sprayed into each corresponding filter bag through the orifices of the spray pipe and the venturi. The filter bag instantaneously expands sharply, causing the dust accumulated on the surface of the filter bag to fall off. The filter bag returns to its initial state. The cleaned dust falls into the ash bucket and is discharged from the body through the ash removal system.

[0003] In the prior art, for example, application No. 201921107890.0 discloses a mechanical pulse dust cleaning dust collector, which comprises a shell, a sealing plate that divides the shell into an upper shell and a lower shell, a plurality of through holes formed in the sealing plate, a plurality of filter units vertically arranged in the shell, one filter unit installed in one through hole, the filter unit comprising a filter cartridge clamped in the through hole, a hollow center column, an up-down moving mechanism arranged in the center column, a release mechanism connected to the lower end of the up-down moving mechanism, a spring connected to the upper end of the release mechanism, and a piston connected to the release mechanism through the center column.
