By arranging the filter element 701 and the filter cotton 7 between the outer frame 1 and the inner frame 101, the fluid can be filtered when passing through the device.

[0026] The specific usage method and function of this embodiment:

[0027] When the device is moved to the installation position, the two movable blocks 4 and the two sealing blocks 401 can be moved to both sides respectively through the pull ring 501 and the connecting block 5. The movement of the movable block 4 will drive the side plate 402 to move and stretch the tension spring 403. Then, the outer frame 1 and the inner frame 101 are moved to the installation position. The tension of the tension spring 403 can drive the side plate 402, the two movable blocks 4 and the two sealing blocks 401 to move towards the inner frame 101, and the sealing block 401 is made to fit the object passing through the inner frame 101. The sealing block 401 is made of rubber material. After the sealing block 401 fits the object passing through the inner frame 101, the sealing between the inner wall of the inner frame 101 and the installation place can be ensured. Then, the threaded rod 603 is turned into the threaded hole 602 to squeeze the sealing strip 601 made of rubber material, so that the sealing strip 601 deforms to fit the installation place, thereby ensuring the sealing between the outside of the outer frame 1 and the installation place. When the filter cotton 7 and the filter element 701 need to be replaced, the installation rod 302 is turned out from the installation hole 301 and the through hole 3. At this time, the disassembly and installation net a2 and the disassembly and installation net b201 can be removed from between the outer frame 1 and the inner frame 101. Then, the filter cotton 7 and the filter element 701 are taken out from between the outer frame 1 and the inner frame 101, and new filter cotton 7 and filter element 701 are replaced on one side of the partition net 102 between the outer frame 1 and the inner frame 101. Then, the disassembly and installation net a2 and the disassembly and installation net b201 are respectively placed on both sides of the partition net 102, and the through hole 3 and the installation hole 301 are aligned. Then, one end of the installation rod 302 is passed through the through hole 3 and rotated into the installation hole 301 to be threadedly connected thereto, so as to fix the disassembly and installation net a2 and the disassembly and installation net b201 on both outer ends of the partition net 102.
