Description

Technical Field

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

[0002] The filter bag is a key part of the operation of the bag filter. Usually, the cylindrical filter bag is hung vertically in the dust collector. When the filter bag is assembled and used, the technicians usually insert a support frame inside the bag body to provide support for the filter bag.

[0003] However, since the supporting frame is a cylindrical structure and its outer surface is very smooth, when it is inserted into the filter bag for use, the filter bag is easily twisted due to the effect of wind pressure, that is, its overall structure is deformed, thereby reducing the filtering performance of the filter bag.
