A first limiting mounting plate, which is fixedly connected to an adjustable hollow dust collector pipe, is provided above the elastic protective plate. An air storage cylinder, which is slidably and sealingly connected to the limiting piston plate, is fixedly connected to the side of the first limiting mounting plate facing the second limiting mounting plate. The end of the air storage cylinder closest to the first limiting mounting plate is spaced apart. The system includes several second limit drive plates that cooperate with the first limit drive plate to move the first limit mounting plate away from the second limit mounting plate. Several single-pass air inlets are spaced apart at the end of each second limit drive plate near the first limit mounting plate. An air storage hood is located above the first limit mounting plate, cooperating with the first air supply hole and the adjustable hollow dust removal pipe to supply air to the first and second hollow material guide plates. The air storage hood is fixedly connected to the adjustable hollow dust removal pipe. Several single-pass air outlets are located at the top of the air storage cylinder to supply air to the air storage hood.

9. The refined cotton dust removal device according to claim 8, characterized in that: On the side of the gas storage hood away from the adjustable hollow dust removal pipe, there are several elastic pressure stabilizing covers for deformation and pressure stabilization. The elastic pressure stabilizing covers are fixedly connected to the gas storage hood, and the second limit drive plate is fixedly connected to the gas storage cylinder.

10. The refined cotton dust removal device according to claim 9, characterized in that: The upper surface of the second limiting mounting plate is provided with a plurality of first guide plates at both ends. The first guide plates are fixedly connected to the second limiting mounting plate, the first guide plates pass through the first limiting mounting plate, and the first guide plates are slidably connected to the first limiting mounting plate.
