[0031] Working principle: When in operation, pulling the handle opens the sliding door 5, placing the filter 16 on the base 11 between the two stops 12. At this time, the filter 16 slides against the two stops 12 to prevent it from sliding off the base 11. Pushing the filter 16 makes it abut against the fixing plate 27, which in turn moves the fixing plate 27. The movement of the fixing plate 27 compresses the spring 13, which in turn exerts a reaction force on the fixing plate 27. The fixing plate 27 then exerts pressure on the filter 16. Closing the sliding door 5 moves the mounting column 14, which in turn moves the limiting plate 15. The limiting plate 15 then abuts against the filter 16. The fixing plate 27 and the limiting plate 15 work together to fix the filter 16.

[0032] The fixed plate 27 will drive the connecting rod 18 to move, the connecting rod 18 will drive the ring 19 to move, the ring 19 will drive the connecting column 17 to move, and the connecting column 17 will drive the groove 21 to move. Since the moving column 22 is fixedly connected to the limiting rod 24 and the fixed rod 23 and cannot move, the torsion spring 20 cannot move. One end of the connecting column 17 will rotate around the torsion spring 20. As the filter 16 moves, the limiting rod 24 will slide against the inner wall of the slide groove 25, thereby limiting the filter 16 and completing the installation of the filter 16. After the installation is completed, NOx exhaust gas will enter from the feed pipe 4 and enter the filter 16. After being processed by the filter 16, the treated gas will exit from the discharge pipe 3, completing the treatment of NOx exhaust gas.

[0033] When disassembly is required, pulling the handle will open the sliding door 5. The sliding door 5 will move the mounting column 14, which in turn will move the limiting plate 15. After the limiting plate 15 has moved for a period of time, it will no longer be in contact with the filter 16, and the filter 16 will no longer be limited. The spring 13 will then move the fixing plate 27, which in turn will move the filter 16. The filter 16 will then move out of the housing 1, making it easy for staff to quickly remove the filter 16.
