[0023] It can be understood that when the dust-containing gas enters the bag-type dust collector through the dust inlet pipe, the dust with large particles and large specific gravity is settled and falls into the inner cavity of the hopper 3 due to gravity, the gas containing fine dust is purified by being blocked by the dust when passing through the filter bag body 5, and then the gas enters the filter bag body 5 and is extracted by the gas extraction device communicated with the gas outlet end of the gas outlet pipe.

[0024] Please refer to Figures 2-3 In order to improve the efficiency of replacing the filter bag body 5, the replacement mechanism 6 in the embodiment includes a movable plate 601 on the upper side of the filter bag body 5, a clamping block 602 fixed to the lower surface of the movable plate 601, a cloth bag frame 603 fixed to the lower surface of the clamping block 602, an annular groove 604 formed in the lower surface of the clamping block 602, an annular ring 605 arranged in the inner cavity of the annular groove 604, and the filter bag body 5 fixed to the lower surface of the annular ring 605. Two connecting plates are fixed to the left and right ends of the lower surface of the movable plate 601 and located in front of the clamping block 602. The annular ring 605 drives the filter bag body 5 to move downward under the action of gravity until the filter bag body 5 falls off the surface of the cloth bag frame 603. The filter bag body 5 can be separated from the cloth bag frame 603, and then a new filter bag body 5 can be replaced.

[0025] The opposite sides of the left and right connecting plates are fixed with driving motors 606, the output shafts of the driving motors 606 penetrate through one of the connecting plates and extend to the opposite sides of the two connecting plates and are fixed with bidirectional screws 607.
