The connecting block 284 has a screw 285 threadedly connected to its outer wall, and the threaded end of the screw 285 extends into the inner cavity of the connecting block 284 and is rotatably connected to a pressure pad 286. The No. 1 fitting half ring 28, the connecting rod 281 and the No. 2 fitting half ring 282 can fit on the outer surface of the filter bag body 11. The external grounding wire is moved into the inner cavity of the connecting block 284 in advance, and then the screw 285 is tightened so that the pressure pad 286 moves toward the external grounding wire, which can clamp the external grounding wire on the inner wall of the connecting block 284. The static electricity on the filter bag body 11 can be guided to the external grounding wire through the transmission of the wire 283, avoiding the problem that the accumulation of static electricity will cause a large number of dust particles to adhere to the surface of the filter bag body 11. When the filter bag body 11 is sleeved on the outer wall of the receiving cylinder 1, the filter bag body 11 can be limited by the limit ring 12.

[0023] As an implementation method in this embodiment, Figures 1-4 As shown, the alloy arm 21 is fixedly mounted on the back of the receiving cylinder 1, and a support frame 22 is fixedly mounted on the end of the alloy arm 21 away from the receiving cylinder 1. A bidirectional screw rod 23 is rotatably connected to the inner wall of the support frame 22, and a servo motor 24 is fixedly mounted on the left side of the support frame 22.

Connected to the outer wall of the filter bag body 11, the bent rod 26 located below is fixedly connected to the outer wall of the No. 1 fitting half ring 28 at one end away from the sliding seat 25. After the filter bag body 11 is sleeved on the outer wall of the receiving cylinder 1, the servo motor 24 is controlled to work and drive the bidirectional screw rod 23 to rotate, prompting the two sliding seats 25 to move toward each other. The two fixing half rings 27 are moved toward each other by the transmission of the bent rod 26, and the filter bag body 11 sleeved on the outer wall of the receiving cylinder 1 is fixed. At the same time, the two No. 1 fitting half rings 28 also move toward each other, so that the No. 1 fitting half ring 28, the connecting rod 281 and the No. 2 fitting half ring 282 are fitted on the outer surface of the filter bag body 11.

The structure can be installed on the external dust collector with the help of bolts at the top, and the dust filtering work can be carried out through the filter bag body 11. The vibration motor 291 can be controlled to drive the receiving cylinder 1 to vibrate as a whole, and simultaneously promote the filter bag body 11 to vibrate, so that the dust attached to the surface of the filter bag body 11 falls off, and the anti-blocking function is achieved. Through the design of the rubber tube 294, the fin plate 293 and the spring 295, the upper and lower parts of the positioning tube 292 are elastically connected, thereby improving the vibration anti-blocking effect.

[0025] Working principle: The filter bag body 11 is sleeved on the outer wall of the receiving cylinder 1, and then the servo motor 24 is controlled to drive the bidirectional screw 23 to rotate, prompting the two sliding seats 25 to move toward each other, and the two fixing half rings 27 move toward each other to fix the filter bag body 11 sleeved on the outer wall of the receiving cylinder 1. At the same time, the two No. 1 fitting half rings 28 also move toward each other, so that the No. 1 fitting half ring 28, the connecting rod 281 and the No. 2 fitting half ring 282 are fitted on the outer surface of the filter bag body 11. The external ground wire is moved into the inner cavity of the connecting block 284 in advance, and then the screw 285 is tightened to move the pressure pad 286 toward the external ground wire. The external ground wire can be clamped on the inner wall of the connecting block 284. Through the transmission of the wire 283, the static electricity on the filter bag body 11 can be guided to the external ground wire, thereby realizing the function of removing static electricity and preventing blockage.
