Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a large air volume filter cartridge pulse jet dust collector. Background Art

[0002] The pulse filter cartridge dust collector adopts pulse jet online cleaning method. The cleaning process is automatically controlled by the pulse controller. Users can use time control method to clean according to their needs. It is widely used in chemical, pharmaceutical, steel, power plant, carbon, abrasive, wood, smelting, mechanical processing, powder recovery, grain processing, pharmaceutical production, food production, powder transportation, plasma cutting, welding fume and casting industries. The filter cartridge of the current pulse filter cartridge dust collector is fixedly installed inside. The dust collector with large air volume has more gas introduced inside. The fixed filter cartridge is easy to cause slow filtration speed and low filtration adsorption.

[0003] After searching, the utility model with patent publication number CN220071085U discloses a large air volume filter cartridge pulse jet dust collector, which uses an adjustment component to allow dust gas to enter the machine body through the air inlet pipe during dust removal work, and is discharged from the air outlet pipe after being filtered by the filter cartridge. In this process, the motor is started to drive the gear to rotate, and the gear applies thrust to the rotating disk through the disk teeth. The rotating disk rotates uniformly and slowly on the inner side of the ring block through the rolling of the steel ball, so that the filter cartridge constantly changes its position, so that each filter cartridge is alternately close to the outlet of the air inlet pipe to speed up the filtration speed. Although it is convenient to improve the filtering and adsorption efficiency of dust, the shape of the current filter cartridge is fixed, which is a straight cylinder shape. When the filter cartridge is back-blown and cleaned through the air outlet head, the cloth bag outside the filter cartridge is easily formed into an elliptical shape due to the gas flow. Although the dust on the lower side of the filter cartridge can be blown and cleaned, it is not convenient to blow and clean the dust on the upper side of the filter cartridge, and the cleaning efficiency is low. The upper part of the filter cartridge is still easy to be blocked, which easily affects the dust removal efficiency of the large air volume filter cartridge pulse jet dust collector.
