The sum of the length of the sliding block 1231 and the length of the compression spring 1233 when being compressed is smaller than the length of the sliding groove 123, so that the sliding block 1231 can be completely retracted into the sliding groove 123, and the possibility that the mounting ring 21 cannot be placed in the placing groove 121 due to the fact that the length of the sliding block 1231 is too long is reduced. To facilitate the insertion of the mounting ring 21 into the placement groove 121, the slide 1231 is provided with a slope 1232 facing the air-purifying chamber 11. When the mounting ring 21 is placed in the placement groove 121, the side edge of the mounting ring 21 abuts against the inclined surface 1232, the slider 1231 is pressed into the sliding groove 123 under the action of the pushing force from the mounting ring 21, the mounting ring 21 is smoothly placed on the placement groove 121, and then the slider 1231 rebounds under the action of the compression spring 1233 and is clamped into the clamping groove 211 to fix the mounting ring 21.

Referring to fig. 3 and 5, the filter bag 2 includes a frame 22 and a heat-resistant felt 23, the heat-resistant felt 23 is coated outside the frame 22 for keeping the filter bag 2 at a high temperature with a good filtering effect, and the heat-resistant felt 23 is made of PTFE and PPS in a mixed manner. The mounting ring 21 is fixedly connected with the top of the framework 22, the framework 22 comprises reinforcing ribs 222 and reinforcing rings 221, the reinforcing ribs 222 are uniformly arrayed along the circumferential direction of the mounting ring 21 and are welded with the mounting ring 21, and the reinforcing rings 221 are uniformly arrayed along the axial direction of the reinforcing ribs 222 and are welded with each reinforcing rib 222. The cooperation of the reinforcing ring 221 and the reinforcing rib 222 can improve the strength of the filter bag 2, and reduce the effect of the filter bag 2 that the filter effect is reduced by blowing the filter bag 2 askew when the dust-containing gas passes through.

Referring to fig. 2 and 5, after the filter bag 2 works for a certain time, dust adheres to the surface of the filter bag 2, and in order to clean the dust on the surface of the filter bag 2, the pulse blowing assembly 3 is arranged on the outer wall of the dust collector body 1. The pulse jetting subassembly 3 includes gas storage package 31, pulse solenoid valve 33, a plurality of injection pipes 32 and locate nozzle 34 on the injection pipes 32, fixedly connected with mounting panel 35 on the outer wall of dust remover body 1, gas storage package 31 fixed connection is on mounting panel 35, a plurality of injection pipes 32 set up along the length direction array of gas storage package 31, pulse solenoid valve 33 is passed through to a plurality of injection pipes 32 one end and is connected with gas storage package 31, the other end then passes dust remover body 1 and extends to the upside of filter bag 2, nozzle 34 is located directly over every filter bag 2. The pulse electromagnetic valve 33 can control the air storage bag 31 to deflate at regular time, compressed air is discharged from the air storage bag 31, passes through the injection pipe 32, and is injected into the filter bag 2 through the nozzle 34 to cause the vibration of the filter bag 2, so that dust accumulated on the filter bag 2 is removed, and the filter bag 2 can maintain a good filtering effect. In order to further increase the dust cleaning effect, a venturi tube 212 is fixedly connected to the mounting ring 21, and the venturi tube 212 is located in the filter bag 2. When compressed air in the air storage bag 31 passes through the venturi tube 212, secondary air flow can be induced to be generated, the blowing acting force on the filter bag 2 is increased, and the efficiency and the effect of removing dust in the filter bag 2 are further improved.

Referring to fig. 5 and 6, in order to further enhance the cleaning effect of the dust accumulated on the filter bag 2, the reinforcing ring 221 is provided with an impact plate 223 facing away from the mounting ring 21, and a vibration plate 224 is provided on a side wall of the impact plate 223. When the nozzle 34 blows, the compressed air generates a downward pressure on the vibration plate 224, so that the vibration plate 224 drives the impact plate 223 to bend downward, and after the nozzle 34 stops blowing, the impact plate 223 rebounds to flap the filter bag 2 for secondary dust removal. To improve the flapping effect, a plurality of striking plates 223 are disposed along the circumferential direction of the reinforcement ring 221 and on different reinforcement rings 221. The striking plate 223 is made of a resilient metal material, such as spring steel.
