[0055] The above-mentioned exhaust gas purification, filtering and cleaning device comprises the following steps:

[0056] S1. Exhaust gas purification

[0057] The induced draft fan 1 is started to work, so that the induced draft fan 1 can generate suction to suck the exhaust gas into the interior of the air duct 2, and then the impurities contained in the exhaust gas can be filtered under the action of the filter frame 4, and the harmful substances contained in the exhaust gas can be filtered and purified under the action of the purifier 6, thereby reducing the impact on the surrounding environment. Then, when the purifier 6 needs to be disassembled for maintenance or replacement during long-term use, the sealing plate 3 is first opened, and then the purifier 6 is lifted upward, so that the purifier 6 can be disassembled;

[0058] S2. Impurity filtration and cleaning

[0059] During the waste gas treatment process, the motor 72 can be started to work, so that the output end of the motor 72 drives the driving shaft 73 to rotate, and the driving shaft 73 drives the connecting shaft 75 to rotate through the transmission of the belt assembly 74, so that the rotating block 77 can make a circular motion along the axis point of the connecting shaft 75, and the long plate 79 can be pushed to move under the mutual cooperation of the push rod 78 and the notch A, so that the long plate 79 can make a circular motion along the axis point of the through-shaft 81, and then the long shaft 701 can push the rectangular plate 702 to move left and right through the notch B, and the rectangular plate 702 will also drive the inclined block 704 to move left and right through the fixed rod 703, so that the impurities filtered by the filter frame 4 can be cleaned, and the situation that the impurities stick to the right side of the filter frame 4 and affect the blockage of the waste gas circulation is reduced, and the performance of the waste gas circulation is further improved, and the practicality of the device is enhanced;

[0060] S3. Impurity removal

[0061] Then, when the long plate 79 swings back and forth along the axis point of the through shaft 81, it will also drive the through shaft 81 to rotate counterclockwise and clockwise, driving the gear 82 to rotate as well. The gear 82 drives the meshing rack 83 to move back and forth, and the rack 83 can drive the push block 84 to move back and forth. The push block 84 can push and clean the impurities filtered by the filter frame 4.

[0062] S4. Impurity cleaning

[0063] When it is necessary to clean the impurities collected inside the collection box 97, the collection box 97 can be first pulled away from the connection box 5 so that the magnetic block 2 99 and the magnetic block 1 96 can be separated from each other, and the plug block 93 can be pulled out from the inner wall of the support groove 92, so that the collection box 97 can be disassembled.

[0064] During actual operation, when this device is used, the staff first aligns the right side of the air duct 2 with the place that needs to be purified, and then starts the induced draft fan 1, so that the induced draft fan 1 can generate suction to suck the exhaust gas into the interior of the air duct 2, and then the impurities contained in the exhaust gas can be filtered under the action of the filter frame 4, and the harmful substances contained in the exhaust gas can be filtered and purified under the action of the purifier 6, thereby reducing the impact on the surrounding environment, and then during long-term use, when the purifier 6 needs to be disassembled, maintained or replaced, first open the sealing plate 3, and then lift the purifier 6 upwards, so that the purifier 6 can be disassembled, which is convenient for the inspection and maintenance of the purifier 6, and at the same time, the purifier 6 is inserted into the inner side of the limit seat at the bottom of the inner wall of the air duct 2, so as to limit the purifier 6 and enable it to work stably.

[0065] During the exhaust gas treatment process, the motor 72 can be started to make the output end of the motor 72 drive the driving shaft 73 to rotate, and the driving shaft 73 drives the connecting shaft 75 to rotate through the transmission of the belt assembly 74, so that the rotating block 77 can make a circular motion along the axis point of the connecting shaft 75, and the long plate 79 can be pushed to move under the mutual cooperation of the push rod 78 and the slot A, so that the long plate 79 can make a circular motion along the axis point of the through-shaft 81, and then the long shaft 701 can push the rectangular plate 702 to move left and right through the slot B, and the rectangular plate 702 will also drive the inclined block 704 to move left and right through the fixed rod 703, so that the impurities filtered by the filter frame 4 can be cleaned, and the situation that impurities stick to the right side of the filter frame 4 and affect the blockage of exhaust gas circulation can be reduced, thereby further improving the performance of exhaust gas circulation and enhancing the practicality of the device.

[0066] When the inclined block 704 scrapes and cleans impurities, it will also drive the limiting sleeve 705 to slide on the outer wall of the slide rod 706, so that the inclined block 704 can move stably, further improving the stability of the inclined block 704 during the moving scraping process, and facilitating the stable scraping of impurities.

[0067] Then, when the long plate 79 swings back and forth along the axis point of the through-shaft 81, it will also drive the through-shaft 81 to rotate counterclockwise and clockwise, driving the gear 82 to rotate as well. The gear 82 drives the meshing rack 83 to move back and forth, and the rack 83 can drive the push block 84 to move back and forth. The push block 84 can push and clean the impurities filtered by the filter frame 4. After the impurities are filtered, the impurities can be cleaned in time without easily causing blockage, thereby improving the smoothness of the impurity filtering process and facilitating better cleaning of the impurities.

[0068] Under the action of the inclined block 704, the impurities filtered by the filter frame 4 can be cleaned, and when the inclined block 704 scrapes and cleans the front side, the rack 83 will drive the push block 84 on the rear side to move backward, driving the push block 84 on the rear side to move backward, so that the inclined block 704 and the push block 84 can make opposite movements, and reserve space for impurities to fall and store inside the connecting box 5, so that the impurities can be better discharged from the inside of the connecting box 5, and the scraping and pushing can be operated synchronously, which reduces the cost during the operation of the device and is also convenient for the staff to operate and use.

[0069] Then, during long-term use, when it is necessary to clean the impurities collected in the collection box 97, the collection box 97 can be first pulled away from the connection box 5 so that the magnetic block 2 99 and the magnetic block 1 96 can be separated from each other, and the plug block 93 can be pulled out from the inner wall of the support groove 92, so that the collection box 97 can be disassembled, which makes it convenient for the staff to clean the impurities inside the collection box 97, and it is also convenient for the staff to operate and use, saving the time consumed in the disassembly and cleaning process, and achieving good operating efficiency.
