Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a filtering device of the bag dust collector with only the filter bag being removed. Background Art

[0002] The pulse bag dust collector adopts the chamber-stopped air pulse jet cleaning technology, which overcomes the shortcomings of conventional pulse dust collectors and chamber back-blowing dust collectors. It has strong cleaning ability, high dust removal efficiency and low emission concentration. It is suitable for the purification of dust-containing gases and the recovery of materials in the metallurgy, building materials, cement, machinery, chemical industry, electric power and light industry industries.

[0003] Chinese patent publication number CN203196480U discloses a pulse filter bag dust collector. The pulse filter bag dust collector comprises a housing with an air inlet flange and an air outlet flange. The interior of the housing is divided into multiple air chambers, each equipped with an air duct baffle. Dust filter bags are installed in each air chamber through a filter bag panel. An upper housing is located above the housing, equipped with a pulse dust cleaning device and an air storage tank. An ash hopper is located below the housing. An auger is located in the lower portion of the ash hopper. A ladder is provided on one side of the housing.

[0004] In the above technical solution, the dust filter bag is installed on the filter bag panel. In order to improve the filtering ability of the dust-removed gas, multiple dust filter bags will be installed on the filter bag panel. The dust filter bag has a certain service life. After the service life is reached, the dust filter bag needs to be replaced. Because the upper end of the dust filter bag is fixed on the filter bag panel and the lower end of the dust filter bag extends to the ash hopper, it is relatively troublesome and complicated to remove the dust filter bag. Therefore, a filtering device for a bag dust collector that only removes the filter bag is needed. Summary of the Invention
