Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, and more specifically, to a breakage-resistant dust removal filter bag. Background Art

[0002] Dust filter bags are a kind of high-efficiency dust removal filter material. Dust filter bags are made of polyester staple fibers, aramid fibers, and nylon fibers. Their service life is generally 2-4 years. They have good air permeability, high dust collection rate, and are easy to clean. The dust removal efficiency can reach 98.99%, and they have good ability to remove PM2.5. However, most traditional dust filter bags have poor flexibility, so when they are disassembled, they may be torn and broken due to operational errors. Moreover, when dust filter bags are installed, they are mostly fixed with bolts, which requires tools when they are disassembled, making replacement more troublesome. Utility Model Content
