[0009] Preferably, the upper cylinder cover and the corrugated cylinder body are fixedly connected by welding, and the lower cylinder cover and the corrugated cylinder body are fixedly connected by welding.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. The corrugated cylinder made of stainless steel fiber material has the advantage of high temperature resistance. At the same time, the corrugated cylinder is in a corrugated shape, which greatly increases the filtration area, thereby increasing the ventilation flow rate and further improving the filtration accuracy. The sealing performance of the dust removal filter cartridge installation can be effectively improved through two sealing rings.

[0012] 2. When the filter cartridge conducts filtration work for a long time, more dust and other impurities will adhere to its inner side. At this time, the staff can pull the pull ring to drive several connecting columns to move downward along the convex ring at the same time, thereby driving the cleaning component to move downward. At this time, several reset springs are compressed to generate elastic force. When the pull ring is released, the cleaning component can be driven back to the initial position through the reset action of the reset spring. Repeating this way can brush the inner side of the corrugated cylinder by moving the cleaning component up and down, so as to brush off the dust and impurities attached to the inner side of the corrugated cylinder, further ensuring the filtration effect of the corrugated cylinder and improving the service life of the dust removal filter cartridge.
