When assembling the assembly plate of the bag filter, the technician inserts the bottom closed end of the dust filter bag through the assembly hole of the assembly plate until the arc-shaped assembly groove on the outer wall of the assembly cylinder of the dust filter bag is engaged with the inner wall of the assembly hole. When the dust filter bag is plugged into the assembly hole of the assembly plate, the outer surface of the bag body and the inner wall of the assembly hole are prone to wear and scratches due to friction. The bag body is made of flexible material, so the smoothness is not good when plugged in. The connection between the assembly cylinder of the bag body and the assembly plate of the bag filter is not conducive to auxiliary limit and sealing, which reduces the assembly efficiency.

[0003] In order to solve the above problems, the present application proposes a dust filter bag that is easy to disassemble and assemble. Utility Model Content

[0028] The guide member 4 is installed outside the bag body 1, and the guide member 4 includes a semicircular rubber strip 401, a conical rubber base 402 and a metal counterweight boss 403. The conical rubber base 402 is fixedly connected to the closed end of the bottom of the bag body 1, and the metal counterweight boss 403 is fixedly connected below the conical rubber base 402. There are multiple semicircular rubber strips 401 and they are equidistantly arranged on the outer wall of the bag body 1.

[0029] The assembly tube 2 is externally installed with a limit member 5 , and the limit member 5 includes a semicircular limit rubber ring 501 , an annular rubber gasket 502 and an inflation valve 503 . The annular rubber gasket 502 is bonded to the lower surface of the semicircular limit rubber ring 501 , and the inflation valve 503 is installed at the inflation port position of the annular rubber gasket 502 .

[0030] It should be noted that a guide member 4 is installed on the outside of the bag body 1. Under the protective effect of the guide member 4 on the bottom counterweight and the outer wall of the bag body 1, during the insertion process of the assembly plate relative to the bag-type dust collector, the bag body 1 with the counterweight is convenient to spread, the insertion process is smoother, and the outer wall of the bag body 1 will not directly rub against the assembly plate, thereby improving the assembly efficiency; the limit member 5 is installed above the arc-shaped assembly groove 3 of the assembly cylinder 2. When the bag body 1 is installed relative to the assembly plate, the limit member 5 assists in limiting the assembly cylinder 2, and the limit member 5 improves the sealing of the connection between the assembly cylinder 2 and the assembly plate of the bag-type dust collector.

[0031] Example 2

[0032] In this embodiment, if Figure 2 As shown, the top of the semicircular rubber strip 401 extends to the lower surface of the assembly tube 2 and is fixedly connected, and the bottom of the semicircular rubber strip 401 is fixedly connected to the conical rubber base 402 .

[0033] It should be noted that the guide member 4 includes a semicircular rubber strip 401, a conical rubber base 402 and a metal counterweight boss 403. The semicircular rubber strip 401 is fixedly connected to the outer wall of the bag body 1, so when the assembly plate of the bag dust collector is plugged into the bag body 1, the semicircular rubber strip 401 will contact the inner wall of the assembly hole to protect the outside of the bag body 1 from wear; the conical rubber base 402 and the metal counterweight boss 403 perform counterweight treatment on the bottom end of the bag body 1, and the plug-in process is smoother.
