[0032] More specifically, when the user needs to disassemble the filter bag body 3, the user can rotate the fastening ring 12 to disengage it from the top block 9. At this time, the spring 10 will push the pin 7 out of the slot 11, thereby separating the annular ring 4 and the mounting ring 5, so that the filter bag body 3 can be disassembled separately, which is convenient for replacement and reduces usage costs. The user can also use the first Velcro 13 and the second Velcro 15 to install the reinforcement ring 14 and the reinforcement strip 16 to the outer end of the filter bag body 3 to increase the overall firmness of the filter bag body 3. This design can protect the filter bag body 3 and prevent the filter bag body 3 from breaking due to pulling during disassembly.

[0033] See also Figure 1 and Figure 6 As an implementation method for increasing the service life of the filter bag body 1: the filter bag body 3 includes a base layer 18, a filter layer 19 is provided on the inner wall of the base layer 18, a flame retardant layer 20 is provided on the outer wall of the base layer 18, an antistatic layer 21 is provided on the outer wall of the flame retardant layer 20, and a wear-resistant layer 22 is provided on the outer wall of the antistatic layer 21.

[0036] Specifically, the filter bag body 3 can be positioned and installed to facilitate later fixation.

[0037] To sum up, when the overall device is in use: when the user needs to disassemble the filter bag body 3, the user can rotate the fastening ring 12 to separate it from the top block 9. At this time, the spring 10 will push the pin 7 out of the slot 11, thereby achieving the effect of separating the annular ring 4 and the mounting ring 5, so that the filter bag body 3 can be disassembled separately, which is convenient for replacement and reduces the cost of use. The user can also use the first Velcro 13 and the second Velcro 15 to install the reinforcement ring 14 and the reinforcement strip 16 to the outer end of the filter bag body 3 to increase the overall firmness of the filter bag body 3. This design can protect the filter bag body 3 and prevent the filter bag body 3 from breaking due to pulling during disassembly. By arranging a flame retardant layer 20 inside the filter bag body 1, its high temperature resistance can be increased to prevent the filter bag body 3 from being corroded by high temperature. By arranging an antistatic layer 21, it is avoided that static electricity generates sparks that ignite the flammable coal dust inside the filter bag body 3. By arranging a wear-resistant layer 22, the wear resistance of the filter bag body 3 can be increased, so that it can be used for a longer time.

[0038] When the user needs to disassemble the filter bag body 3, the user can rotate the fastening ring 12 to separate it from the top block 9. At this time, the spring 10 will push the pin 7 out of the slot 11, thereby separating the annular ring 4 and the mounting ring 5, so that the filter bag body 3 can be disassembled separately.
