The sealing mechanism is arranged on one end surface of the ventilation pipe, and the outer surface of the ventilation pipe is arranged on a supporting mechanism. The ventilation pipe connects the two ventilation pipes, and then pulls the pull rod, the sliding block slides in the sliding groove to compress the spring, and one end of the pull rod is received in the sliding groove, and then the connecting block is inserted into the limit groove, and a limit hole is provided on the connecting block, and by loosening the pull rod, the spring rebounds, and one end of the pull rod is stuck in the limit hole, so that the two ventilation pipes are connected and fixed, and a sealing ring is placed at the joint of the ventilation pipes, which can effectively prevent gas leakage at the joint of the ventilation pipes, thereby completing the easy installation and better sealing effect of the ventilation pipe. Although the product has a good sealing effect, it is unable to filter debris and quickly replace the filter plate, which easily causes debris to enter the interior of the ventilation pipe, causing the ventilation pipe to be blocked, and reduces the efficiency of filter plate replacement and maintenance. The practicality is poor and needs to be improved. Utility Model Content

[0023] Embodiment 2

[0024] See also Figure 1 ,2 4. A scraper 12 is fixedly installed on the side of the rotating frame 2 to automatically clean the filter plate 3. A fixing block 13 is fixedly installed on the lower surface of the shell 1 to install the guide rod 14. The inside of the fixing block 13 is slidably connected with the guide rod 14 to allow the collection box 15 to be installed in place. The surface of the guide rod 14 is fixedly installed with a collection box 15 to collect debris.
