Double-layer sealing access door of bag type dust remover

Abstract

The invention provides a double-layer sealing access door of a bag type dust remover. The double-layer sealing access door comprises a dust removal box body, springs, compression blocks, compression screw nuts, gaskets, fixing studs, a pull handle, an access door panel, heat insulation rock wool, a lower sealing body, square sealing strips and Y-shaped sealing strips, wherein one end of each spring is welded and fixed on the dust removal box body, and the other end of each spring is fixed at the outer side under the corresponding compression block, and supports the corresponding compression block; the other side of each compression block is arranged on the access door panel; each fixing stud passes through the center of the corresponding compression block to be welded on the dust removal box body; and each compression block tightly compresses the access door panel through the corresponding compression screw nut and the corresponding gasket arranged on the compression block. After the access door covers the box body of the dust remover, the compression screw nuts are tightly screwed; each compression element tightly compresses the corresponding square sealing strip; meanwhile, each Y-shaped sealing strip is downwards pressed; and through the elastic effect of the Y-shaped sealing strips, the square sealing strips and the Y-shaped sealing strips are enabled to be tightly attached to the box body of the dust remover, so that the access door of the bag type dust remover reaches the double-layer sealing effect.

Description

technical field [0001] The invention relates to a bag-type dust collector, in particular to a double-layer sealed maintenance door of the bag-type dust collector. Background technique [0002] With the increasingly strict national emission standards, the requirements for dust removal equipment are becoming more and more stringent. As the first choice for dust removal equipment that meets the emission standards, the bag filter has higher and higher requirements for its structure, especially in terms of equipment sealing. If the existing bag filter adopts a single-layer inspection door, the cost is low, but the air leakage rate is high and the sealing effect is not good. If a double-layer inspection door is used, the sealing effect is good and the air leakage rate is reduced, but the structure changes greatly and the production workload And the cost will increase a lot. [0003] Therefore need to invent a kind of simple in structure, good sealing effect bag type dust catcher ...
