Next, a fan blade 9 is fixedly connected to the surface of the support shaft 7, a protective cover 10 is movably connected to the outside of the support shaft 7, a fixing ring 11 is fixedly connected to the outside of the support shaft 7, a baffle 12 is fixedly connected to the upper end of the support shaft 7, the baffle 12 contacts the protective cover 10, and the protective cover 10 is limited by the baffle 12. A spring 13 is provided on the outside of the support shaft 7, one end of the spring 13 is fixedly connected to the protective cover 10, and the other end of the spring 13 is fixedly connected to the fixing ring 11. The protective cover 10 is elastically supported by the spring 13.

[0022] Please see Figure 1 , Figure 2 , Figure 4The mounting mechanism 5 includes a screw ring 51. The screw ring 51 is threadedly connected to the outer side of the support 4. The screw ring 51 is rotatably connected to the hollow cylinder 1. An inclined block 52 is slidably connected inside the screw ring 51, contacting the hollow cylinder 1. A push rod 53 is fixedly connected to the surface of the inclined block 52. A compression spring 54 is provided on the outer side of the push rod 53. One end of the compression spring 54 is fixedly connected to the inclined block 52, and the other end is fixedly connected to the screw ring 51. By providing the compression spring 54, the inclined block 52 can be easily reset. The rod 53 and the screw ring 51 are slidably connected. A slip ring 55 is slidably connected to the outside of the screw ring 51. The slip ring 55 contacts the top rod 53. By setting the slip ring 55, the top rod 53 is limited. By rotating the screw ring 51 and the support 4 to make threaded movement, the inclined block 52 can be easily engaged and disengaged from the hollow cylinder 1 under the elastic action of the compression spring 54. This makes it easy to disassemble and assemble the hollow cylinder 1 and the support 4, and makes it easy to disassemble and replace the cloth bag 2.

[0023] The specific implementation process of this utility model is as follows: During installation, the cloth bag 2 is inserted into the hollow cylinder 1, and the opening of the cloth bag 2 is reversed and fitted onto the elastic seat 3. Then, the sliding ring 55 and the top rod 53 are disengaged, and the hollow cylinder 1 is moved upward. When the upper edge of the hollow cylinder 1 contacts the inclined block 52, the inclined block 52 slides into the screw ring 51, thereby compressing the compression spring 54 until the hollow cylinder 1 moves upward to the point where the edge is misaligned with the inclined block 52. The compression spring 54 resets, causing the inclined block 52 to extend out of the screw ring 51 and limit the hollow cylinder 1. Then, the sliding ring 55 is released, and the sliding ring 55 moves downward and contacts the top rod 53, limiting the top rod 53. Then, the screw ring 51 and the support 4 are rotated to make a threaded movement, thereby causing the inclined block 52 to press upward against the hollow cylinder 1, thereby causing the cloth bag 2 to be compressed by the elastic seat 3 and the support 4. With clamping and fixing, the top rod 53 is limited by the slip ring 55, and the screw ring 51 and the support 4 make threaded movement by rotating, so that the inclined block 52 can be easily controlled to engage and disengage with the hollow cylinder 1 under the elastic action of the spring 54, so that the hollow cylinder 1 and the support 4 can be easily disassembled and assembled, so that the filter bag 2 can be easily disassembled and replaced. When the high-speed flue gas flow impacts the fan blade 9, the air flow drives the fan blade 9 to drive the support shaft 7 to rotate, and the support shaft 7 drives the scraper 8 to rotate, so that the scraper 8 scrapes against the filter bag 2, so that the dust in the filter bag 2 can be easily concentrated, so that the filter bag 2 is not easily blocked by dust, so that the filter bag 2 is not easily blocked. At the same time, the protective cover 10 protects the fan blade 9 to prevent particulate matter from impacting the fan blade 9 and causing damage to the fan blade 9.
