Pleated filter cartridge device with air valve

Abstract

The invention discloses a pleated filter cartridge device with an air valve, and the device comprises a dust remover box body and a filter cartridge; the filter cartridge is fixed in the dust remover box body through a pattern plate, the pattern plate divides the interior of the dust remover box body into an air purification chamber and a filter chamber, one side of the air purification chamber is provided with a pulse blowing device, and the bottom of the filter chamber is provided with a cinder valve; the filter cartridge comprises a top plate, a filter material, a bottom plate and an impact plate, an air valve is arranged on an inner ring of the top plate and hinged to an inner ring of the pattern plate through a damper, the impact plate is arranged in the pleated filter cartridge, the two ends of the impact plate are connected with the air valve and the bottom plate through supporting frames respectively, and the top plate is connected with the bottom plate through multiple sets of supporting strips; and a filter material is fixed between two adjacent groups of supporting strips. According to the device, the damper and the air valve are arranged, so that the air valve cannot be quickly opened during dust removal, the recovery time of filtered air flow is prolonged, dust cakes have enough time to fall to the dust discharging valve, back suction of dust after dust removal is reduced, and the pulse dust removal effect is ensured.

Description

technical field [0001] The invention relates to the technical field of dust filtration, in particular to a pleated filter cartridge device with a damper. Background technique [0002] With the continuous expansion of production scale and frequent occurrence of air pollution, the problem of dust emission has increasingly attracted the attention of residents and scholars. The dust discharged into the environment not only reduces visibility, affects people's normal travel, but also endangers the health of residents. People put forward a variety of methods for dust control, among which the pleated filter cartridge dust collector is favored by users for its high dust removal efficiency and small footprint. [0003] The principle of the pleated filter cartridge dust collector is to intercept the dust in the air by filtering. With the use of the equipment, the filter material will be covered with dust, which will increase the filter resistance. In order to ensure high filtration ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a pleated filter cartridge device with a damper, which is used to solve the problem that the dust that has just left the filter element is difficult to settle to the ash in time due to the rapid stop of blowing when the existing filter cartridge device is cleaning. bucket, so it is easy to be adsorbed to the filter material again with the recovery of the filter air flow, resulting in the problem of unsatisfactory cleaning effect
