[0027] like Figure 1-Figure 3 As shown, the filter assembly includes two bar slide rails 5 fixedly connected to the inner wall of the exhaust gas purification box 3, a filter frame 6 is slidably connected in the two bar slide rails 5, a multi-effect filter is arranged inside the filter frame 6, a retention hole is opened on the side wall of the exhaust gas purification box 3, and the end of the filter frame 6 is located at the retention hole;

[0028] The filter frame 6 is connected to the two strip slide rails 5 in the exhaust gas purification box 3 through the retention hole. The filter frame 6 and the strip slide rails 5 can support the rapid installation and removal of the filter frame 6 and the exhaust gas purification box 3.

[0029] like Figure 1-Figure 3As shown, a filter frame fixing component is provided on the outer wall of the exhaust gas purification box 3, and the filter frame fixing component includes two telescopic rods fixedly connected to the outer wall of the exhaust gas purification box 3, and the ends of the two telescopic rods away from the exhaust gas purification box 3 are fixedly connected with a pull rod 10, and the outer walls of the two telescopic rods are sleeved with a tension spring 13, and the two ends of the tension spring 13 are respectively fixedly connected to the outer wall of the exhaust gas purification box 3 and the pull rod 10, and a plurality of latch shafts 11 are fixedly connected to the middle of the pull rod 10, and a slot 12 is provided on the filter frame 6, and the latch shaft 11 matches the slot 12, and a through hole is provided on the side wall of the exhaust gas purification box 3, and the latch shaft 11 matches the through hole;

[0030] Before the filter frame 6 is fully inserted into the bar slide rail 5, pull the pull rod 10 so that the pin shaft 11 will not block the filter frame 6. After the filter frame 6 is fully inserted into the bar slide rail 5, the pin shaft 11 corresponds to the slot 12 on the filter frame 6. Relax the pull rod 10 and pull the pull rod 10 to move by stretching the spring 13, so that the pin shaft 11 and the slot on the filter frame 6 are automatically plugged in and matched, so that the filter frame 6 can be quickly installed and fixed, simplifying the loading and unloading operations of the filter structure, which is beneficial to improving the loading and unloading and maintenance efficiency of the filter structure.

Before the filter frame 6 is fully connected to the strip slide rail 5, the pull rod 10 is pulled so that the latch shaft 11 does not block the filter frame 6. After the filter frame 6 is fully connected to the strip slide rail 5, the latch shaft 11 corresponds to the slot 12 on the filter frame 6. The pull rod 10 is loosened, and the pull rod 10 is pulled to move by the tension spring 13, so that the latch shaft 11 and the slot on the filter frame 6 are automatically plugged and matched, so that the filter frame 6 can be quickly installed and fixed, simplifying the loading and unloading operation of the filter structure, which is conducive to improving the loading and unloading maintenance efficiency of the filter structure;
