Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically a self-cleaning dust collector filter bag. Background Technology

[0002] Dust collector filter bags are a type of high-efficiency dust collection material. They have good air permeability, high dust collection efficiency, and certain resistance to acids, alkalis, and heat. The weaving process uses multi-sided napping, which increases the fabric thickness and elasticity, resulting in excellent dust collection performance. Dust collector filter bags are made from polyester staple or long fibers, which have good air permeability and high dust collection rate.

[0003] The "Automatic Cleaning Dust Collector Filter Bag" disclosed in application number "202323304082.2" includes a filter chamber, an installation ring fixedly fitted on the outer peripheral wall of the filter chamber, an installation plate placed inside the filter chamber, four filter screens embedded in the outer peripheral wall of the filter chamber, a movable plate placed inside the filter chamber, a brush layer fixedly fitted on the outer peripheral wall of the movable plate, a limit hole opened on the right inner wall of the filter chamber, a drive motor fixedly installed on the left side of the installation plate, and a screw fixedly connected to the output end of the drive motor, one end of which passes through the installation plate and the movable plate and extends into the limit hole. This automatic cleaning dust collector filter bag, through the action of the brush layer, facilitates the cleaning of the filter screens, making it convenient for operators to use. The threaded connection between the screw and the movable plate facilitates the movement of the movable plate, making it easy for operators to operate. Simultaneously, the clearance fit between the fixed rod and the fixed hole facilitates the installation of the installation plate, making it more convenient and practical.

[0004] However, the above method still has the following drawbacks: the filter screen can be cleaned by moving the plate and brush layer, but the filter bag has a certain thickness, and the brush layer is difficult to cover the outer surface of the filter bag. When cleaning the outer surface, dust can easily clog the filter pores, resulting in poor cleaning effect on the filter bag. Utility Model Content
