The placing assembly comprises a baffle 3, the baffle 3 is integrally formed with a second sliding rail 31 matched with the sliding channel 13, the second sliding rail 31 is integrally formed with a plug-in column 311, and the first sliding rail 21 is provided with the plug-in column 311 matched with a first plug-in groove 211.

[0035] Specifically, the plug-in column 311 is plugged in the first plug-in groove 211, the placing assembly and the sealing block 2 are connected through the plugging of the plug-in column 311 and the first plug-in groove 211. By pulling the baffle 3, the placing assembly and the sealing block 2 slide together in the shell 1, and when the placing assembly is pulled out of the shell 1, the filter core on the placing assembly can be removed for replacement.

[0036] Further, the placing assembly is two, the first slot 211 is opened on the opposite side wall of the first slide rail 21, and the first slots 211 on the opposite side walls of the first slide rail 21 are not communicated with each other. When replacing the filter element, the new filter element can be installed on the idle placing assembly, and the placing assembly with the new filter element is butted on the sealing block 2 from the left of the opening 12, and the placing assembly in the shell 1 is pushed from the left side of the shell 1 to the right side, at this time, the placing assembly in the shell 1 is withdrawn, and the placing assembly with the new filter element is pushed into the shell 1, which can greatly improve the speed of replacing the filter element.

[0037] Specifically, the left side wall and the right side wall of the first slide rail 21 are provided with the first slot 211, and when replacing, the placing assembly is placed on the left side of the shell 1, the inserting column 311 is inserted into the first slot 211 on the left side wall of the first slide rail 21, the connection between the left placing assembly and the sealing block 2 is realized, and then the placing assembly is pushed to the right. At this time, the placing assembly in the shell 1 slides out of the shell 1, and then the old filter element on the placing assembly is removed, and the placing assembly is in an idle state, waiting for the next time when the filter element is replaced to install the filter element thereon to repeat the above-mentioned action to complete the rapid replacement of the filter element.

[0038] Further, as shown in Figure 3 , the second slide rail 31 is welded with the protective plate 32, and the limiting frame 33 is welded on the protective plate 32. The filter screen can be placed between a pair of protective plates 32, and the limiting frame 33 can block the filter screen. Specifically, in use, the waste gas is blown into the shell 1 from the air inlet pipe 11, the limiting frame 33 blocks the filter screen to prevent the filter screen from sliding on the protective plate 32, ensures the filtering effect of the filter screen, and at the same time, the position of the filter screen does not change, which is beneficial to be pulled out from the opening 12 when replacing.

[0039] It is worth noting that since the sealing block 2 slides in the shell 1, the placing assembly is detachably connected to the sealing block 2, in order to fix the placing assembly on the sealing block 2 and prevent the sealing block 2 from sliding out of the shell 1 in use, as shown in Figures 2 to 6 , the locking assembly includes a pressing plate 43, the pressing plate 43 is integrally formed with a pair of first inserting plates 431 and second inserting plates 432, the sealing block 2 is provided with a second slot 22 matched with the second inserting plate 432, the upper panel of the shell 1 is provided with a first through slot 14 matched with the second inserting plate 432, and the protective plate 32 is provided with a second through slot 321 matched with the first through slot 14.

[0040] Specifically, the second plug plate 432 is inserted into the second slot 22 through the first through slot 14 and the second through slot 321, so as to lock the sealing block 2 in the shell 1. The distance between the first plug plate 431 and the side wall of the shell 1 is equal to the thickness of the baffle 3. When the second plug plate 432 is inserted into the second slot 22, the side wall of the first plug plate 431 is in contact with the side wall of the baffle 3, so that the side wall of the baffle 3 away from the first plug plate 431 is in contact with the shell 1.

[0041] Further, the first plug plate 431 and the second plug plate 432 are wrapped with rubber layers. The rubber layer on the first plug plate 431 can increase the pressure between the baffle 3 and the shell 1, and can strengthen the sealing between the first plug plate 431 and the shell 1, so as to prevent the exhaust gas from leaking. The rubber layer on the second plug plate 432 can block the second through slot 321 and the first through slot 14, so as to prevent the exhaust gas from leaking from the second through slot 321 and the first through slot 14.

[0042] Further, the locking assembly further comprises a fixed frame 4, the pressing plate 43 is slidingly connected in the fixed frame 4, the fixed frame 4 is fixedly connected with a threaded sleeve 41, the threaded sleeve 41 is threadedly connected with a screw rod 42, one end of the screw rod 42 is welded with a thrust ball bearing 44, the thrust ball bearing 44 away from the screw rod 42 is welded and connected to the pressing plate 43, and the screw rod 42 away from the pressing plate 43 is integrally formed with a hand wheel 421.

[0043] Specifically, by rotating the hand wheel 421, the pressing plate 43 can vertically slide in the fixed frame 4. When the placing assembly and the sealing block 2 are fixed, the second plug plate 432 can be inserted into the second slot 22 by rotating the hand wheel 421 clockwise. The vibration of the exhaust gas purification filter during work can also be prevented, so that the second plug plate 432 cannot slide out of the second slot 22 and lose the locking effect.

[0044] Further, after long-term use, more dust accumulates on the inner wall of the shell 1. When the inner wall of the shell 1 is cleaned, the placing assembly and the sealing block 2 in the shell 1 can be pulled out, and the shell 1 does not need to be disassembled for cleaning.

[0045] When in use, the hand wheel 421 is rotated counterclockwise, so that the pressing plate 43 slides upward, the locking of the placing assembly is released, the placing assembly is pulled out of the shell 1, the filter element on the placing assembly is replaced, the placing assembly is slid into the shell 1, the hand wheel 421 is rotated clockwise, so that the second plug plate 432 is inserted into the second slot 22, and the replacement of the filter element is completed.
