Filter bag device of pulse dust collector

Abstract

The invention belongs to the technical field of dust collecting equipment, and particularly discloses a filter bag device of a pulse dust collector. The device comprises a filter bag, wherein a rotating shaft is arranged in the filter bag, fan blades are arranged on the rotating shaft, a plurality of cams are arranged on the rotating shaft, bulge parts of two adjacent cams face oppositely, and sliding grooves are formed in curved surfaces of the cams; a plurality of movable rod groups are arranged in the filter bag; each movable rod group comprises two movable rods, one end of each movable rodis clamped in the corresponding sliding groove, the other ends of the two movable rods are fixedly connected with the filter bag, and clappers are glidingly connected to the two movable rods; a firstmagnet and a second magnet are arranged on the bulge part and a cylinder part of each cam respectively, third magnets are arranged on the clappers, the magnetic poles of the sides, close to each other, of the first magnet and the third magnets are identical, and the magnetic poles of the sides, close to each other, of the second magnet and the third magnet are opposite. With the scheme, the filter bag can shake back and forth when being cleaned by a blowing device, and the clappers can also beat the filter bag back and forth, so that the cleaning effect is good.

Description

technical field [0001] The invention belongs to the technical field of dust removal equipment, in particular to a filter bag device of a pulse dust collector. Background technique [0002] Since the pulse bag filter came out in the 1950s, it has been widely used at home and abroad, and has been continuously improved. It has made great progress in purifying dusty gases. Large size, small footprint, high purification efficiency, reliable operation, simple structure, and small maintenance. At present, the combination of cage-type steel framework and flexible filter bag is mostly used in China, but the use of cage-type steel framework has the following defects: welding requires special equipment, many welding points, heavy workload, high cost, and transportation, loading and unloading, installation , The process of changing bags is troublesome and time-consuming. When the air blowing device is used to blow air and dust inside the filter bag, since the filter bag and the frame ...
