[0030] It should be noted that the fence-type air filter, through the adjustment and disassembly mechanism set up, can pull the pull rod 12 and the movable rod 11 to drive the movable plate 9 to move and compress the reset spring 8, so that the limit pin 13 moves out of the inner side of the fixed seat 5, and then the filter body 6 can be clamped, and the reset spring 8 drives the limit pin 13 to reset and move to fix the fixed seat 5 and the filter body 6, so as to facilitate the limiting fixation and disassembly of the filter body 6, and the fixing bolts 4 can be used to fix the side sealing plate 2 on both sides of the lower base plate 1 and the upper base plate 3, or the side sealing plate 2 can be removed, thereby improving the flexibility of the device.

[0031] The working principle of the above embodiment is:

[0032] When using the fence-type air filter, first, pull the pull rod 12, the pull rod 12 drives the movable rod 11 to move, the movable rod 11 moves and drives the movable plate 9 to move, the movable plate 9 moves stably under the limit of the limit rod 10, and compresses the reset spring 8, and at the same time, the movable plate 9 drives the limit pin 13 to move, until the limit pin 13 moves out of the placement groove inside the fixed seat 5, and then the filter body 6 can be inserted into the placement groove inside the fixed seat 5, and then slowly release the pull rod 12, the reset spring 8 starts to automatically reset, and drives the movable plate 9 and the limit rod 10 to reset and move, until the limit rod 13 is inserted into the slot inside the fixed seat 5 again;

[0033] The fixing seat 5 and the filter body 6 are plugged and fixed, and finally the two side sealing plates 2 can be fitted on both sides of the lower base plate 1 and the upper top plate 3, and then the fixing bolts 4 are used to fix the side sealing plates 2 on both sides of the lower base plate 1 and the upper base plate 3 to form an internal hollow space with both sides flowing through the outside closed space, so that the whole device can be fixed in the pipe or area that needs to be filtered to filter the air. When the filter body 6 needs to be removed and cleaned, the fixing bolts 4 are first removed, and then the side sealing plate 2 on one side can be removed, and then the clamping rod 12 is pulled, and the pull rod 12 drives the limit pin 13 to disengage from the inside of the fixing seat 5, so that the internal filter body 6 can be removed, which is convenient for cleaning the filter body 6, helps to maintain the subsequent filtering effect, and greatly improves the flexibility and practicality of the device.
