Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, in particular to a wear-resistant dust removal filter bag. Background Art

[0002] The dust filter bag is a highly efficient dust removal filter material with good ventilation performance, high dust removal efficiency, and certain acid, alkali and heat resistance. Multi-sided brushing is used in the weaving process to increase the thickness of the fabric, making it elastic, and the dust removal effect is very good. The durable filter bag is made of pure, high-quality melt-blown ultrafine fiber filter cloth that is finely hot-melted or sewn. The filter bag has excellent chemical stability and heat resistance, and is the highest performance representative in the filter material industry.

[0003] The patent document with the prior art publication number CN215654311U provides a wear-resistant dust filter bag, including a filter bag body and a cage, the top outer wall of the filter bag body is fixedly connected with a rubber ring, and the outside of the filter bag body is provided with a mounting cylinder, a fixing ring is welded on the inner side of the middle part of the cage, and the outer wall of the fixing ring is rotatably connected with a rotating drum, the outer wall of the rotating drum is fixedly connected with a rotating plate, and anti-scratch blocks are provided on both sides of the rotating plate, the top of the cage is fixedly connected with a fixing block, and the outer wall of the fixing block is snap-connected with a mounting plate, and a fixing hole is opened on the top of the mounting plate. When the wear-resistant dust filter bag is used, the cage can be spliced ​​according to the use length, and the fixing blocks and fixing holes of the two sections of the cage are directly aligned, snap-connected and rotated, so that the cage can be spliced ​​and used, and the operation is simple, and it is convenient to adjust and assemble according to the use length, thereby avoiding the non-adjustable situation of the integrated cage, thereby increasing the applicability of the cage.

[0004] However, during the use of existing wear-resistant dust filter bags, since the gas contains floating dust and impurities, and these dust and impurities will generate friction when passing through the dust filter bags, the dust filter bags have poor wear resistance. When filtering for a long time, the dust filter bags are easily damaged due to long-term friction, resulting in a short service life of the dust filter bags. For this reason, we propose a wear-resistant dust filter bag. Utility Model Content
