Double-sealing structure for access door cover of upper box body of bag-type dust collector

Abstract

The invention discloses a double-sealing structure for an access door cover of an upper box body of a bag-type dust collector. During sealing, the L-shaped folded plate is arranged on the outer side of the door frame; foaming rubber strips are respectively arranged at the joint of the access door cover and the door frame and the joint of the L-shaped folded plate and the access door cover, so thatdouble sealing structure is achieved, that is, an internal seal is added on the basis of an original external seal and finally, the air leakage rate of the dust remover can be reduced; the double-sealing structure achieves reduction of operating costs, and improves stability of dust remover operation; during the sealing, the door frame is pushed forward, the second stretching rod is pushed through the extrusion rod; under the cooperation of the movable hose, the first stretching rod is pushed, the annular plate is pushed up, jacking of the rubber air bag can be achieved, under the cooperationand extrusion, the annular plate can be extruded to block the joint of the door frame and the access door cover, internal extrusion sealing can be stably achieved, and the sealing performance of thedust remover can be better guaranteed; therefore, the effect is more stable when the dust remover is used in cooperation with the annular plate.

Description

technical field [0001] The invention relates to the field of dust collector equipment, in particular to a double-seal structure for the inspection door cover of the upper box of the bag dust collector. Background technique [0002] The bag filter is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt. The gas is filtered. When the dusty gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the effect of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust will be blocked. stay to purify the gas; [0003] The existing single-seal structure of the door cover only seals outside the box body, and installs a foam rubber strip on the inner edge of the door cover. The air leakage of the dust collector caused by insufficient sealing will directly lead to excessive energy...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a double-seal structure for the inspection door cover of the upper box of the bag filter, which solves the problem that the air leakage of the dust collector caused by insufficient sealing will directly lead to excessive energy consumption of the induced draft fan of the dust collector and cause unnecessary power consumption.
