Description

Technical Field

[0001] The present application belongs to the technical field of dust filter cartridges, and specifically relates to a dust filter cartridge with a self-cleaning structure. Background Art

[0002] Cartridge dust collectors use cartridges as filter elements or use pulse jets. Cartridge dust collectors can be divided into oblique insertion, side-mounted, hanging-mounted, and top-mounted types based on their installation methods.

[0003] A search of the patent document CN 221333294 U discloses an industrial dust filter cartridge. Most industrial dust filter cartridges are long and cylindrical, and when used, they are installed in an industrial dust collector. The industrial dust collector inevitably shakes inside during use, and prolonged shaking causes significant impact and extrusion to the industrial dust filter cartridge. Over time, the industrial dust filter cartridge deforms, damaging its overall structure. This also affects the normal use of the industrial dust filter cartridge, and therefore, requires improvements based on the existing technical deficiencies. The industrial dust filter cartridge comprises a first mounting plate mounted on one end of the dust filter cartridge and a second mounting plate mounted on the other end of the dust filter cartridge. Two fixing rings are fixedly sleeved on the body of the dust filter cartridge. One side of the slide is connected to a fixing mechanism, and a slide bar is movably mounted inside the slide bar, with one end of each slide bar connected to a set of interlocking mechanisms.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0005] After long-term filtration, a large amount of dust will adhere to the wall of the filter cartridge, which will cause clogging of the cartridge wall and affect the filtration effect. At the same time, when cleaning the cartridge wall, the cartridge wall needs to be removed, which is time-consuming. Utility Model Content

Under the driving of the reverse airflow, the airflow is washed from top to bottom through the lower end outlet of the conveying pipe, so that the dust attached to the outer surface of the dust removal filter cylinder body is stripped. When the dust is stripped, the upper support plate is moved upward by the hydraulic rod, so that the telescopic cylinder wraps the dust removal filter cylinder body. The blown dust falls into the inside of the drawer through the gap between the fixed ring and the outer end of the inner wall of the telescopic cylinder for collection. Through the cooperation of the above structure, the dust on the outer wall of the dust removal filter cylinder body can be cleaned in time, and the scattered dust generated during cleaning is prevented, thereby increasing the cleaning work.

When the dust filter cylinder body 1 needs to be replaced after long-term use, the dust filter cylinder body 1 can be taken out and replaced separately through the threaded connection between the lower end of the dust filter cylinder body 1 and the connecting ring 701, so as to reduce the material loss. Through the cooperation of the above structure, the dust on the outer wall of the dust filter cylinder body 1 can be cleaned in time, and the scattered dust during cleaning is prevented, so that the cleaning work is increased.
