Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically to an easy-to-assemble dust collector bag. Background Technology

[0002] Dust collector bags are considered the heart of baghouse dust collectors. They are generally called dust collector bags or dust filter bags and are a key part of the operation of baghouse dust collectors. Typically, cylindrical filter bags are suspended vertically in the dust collector. The fabric and design of dust collector bags should strive for high-efficiency filtration, easy dust removal, and durability.

[0003] Existing dust collector bags are usually installed on dust collectors using metal pressure rings and bolts. Specifically, the open end of the bag is pressed against the hole in the tube sheet by a metal pressure ring, and then multiple bolts are used to lock and fix the pressure ring. The assembly is cumbersome, requiring each bolt to be tightened individually, which consumes a lot of manpower and time. Especially when replacing the bag, the disassembly and installation process is extremely inconvenient. If the bolts are not tightened evenly, it is easy to cause uneven force on the pressure ring, resulting in poor sealing of the bag or local deformation and damage.

[0004] Therefore, there is an urgent need for a dust collector bag structure that can achieve boltless fixing, convenient installation, and reliable sealing. Utility Model Content
