Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, in particular to a multi-cylinder type dust removal filter bag with a large filtering area. Background Art

[0002] Multi-cylinder dust filter bags are often installed inside industrial dust collectors to filter and clean dust. The existing patent number is CN210993357U, a multi-cylinder combined dust filter bag. In the device, the connection block is pulled outward and removed from the connection slot to disconnect the fixed connection between the upper filter cartridge and the lower filter cartridge. Therefore, the upper filter cartridge and the lower filter cartridge can be separated by simply removing the connection block from the connection slot, which reduces the difficulty of disassembling the device and facilitates the staff to clean the lower filter cartridge. When the multi-cylinder dust filter bag is in use, its outer surface area increases, but its length increases accordingly. When installing the assembly plate, the bottom of the dust filter bag is prone to bending or stacking, affecting the filtering effect.

[0003] In order to solve the above problems, the present application proposes a multi-cylinder dust filter bag with a large filtering area. Utility Model Content
