At this time, the suction pump 14 is started to make the exhaust gas after the first filtration in the filter box 11 enter the first fixed box 16 through the first connecting pipe 13 and the second connecting pipe 15. Because water is stored in the first fixed box 16, and the height of the water is lower than the end of the third connecting pipe 18, that is, the water in the first fixed box 16 can absorb and filter the unpleasant gas contained in the exhaust gas. The exhaust gas after absorption and filtration can enter the second fixed box 17 through the third connecting pipe 18, and the second fixed box 17 is provided with a sodium hydroxide solution.

Because the pulleys 21 and the screw rod 24 are connected to each other, during the rotation of the pulley 21, the screw rod 24 can be driven to rotate inside the sleeve 23. Because the screw rod 24 and the slider 26 are threadedly connected, and the slider 26 and the installation box 27 are connected to each other, that is, during the rotation of the screw rod 24, the slider 26 and the installation box 27 are driven to move. During the movement of the installation box 27, multiple groups of spring columns 29 push the cleaning plate 28 to move left and right inside the installation box 27. When the spring columns 29 push the end of the cleaning plate 28 to move to fit the surface of the filter screen 12, the large particles of impurities adhered to the surface of the filter screen 12 during filtering can be cleaned, thereby reducing the large particles of impurities adhered to the surface of the filter screen 12, which is easy to cause the surface of the filter screen 12 to be blocked, thereby improving the overall smoothness of the filter screen 12 when filtering the exhaust gas, and improving the cleanliness of the surface of the filter screen 12.

[0026] like Figure 1 and Figure 2 As shown, a pair of water tanks 3 are fixedly connected to the top of the filter box 11; a water inlet 31 is connected to the top of the water tank 3; a fourth connecting pipe 32 is connected to one side wall of the water tank 3; a water pump 33 is fixedly connected to the end of the fourth connecting pipe 32 away from the water tank 3; the other end of the water pump 33 is fixedly connected to the fifth connecting pipe 34; the other end of the fifth connecting pipe 34 is connected to the inside of the filter box 11, and a high-pressure nozzle 35 is fixedly connected to the end of the fifth connecting pipe 34 away from the water pump 33; when working: water is added to the inside of the water tank 3 through the water inlet 31, and the water pump 33 is started, so that the water inside the water tank 3 enters the inside of the fifth connecting pipe 34 through the fourth connecting pipe 32, and at this time, the high-pressure nozzle 35 can rinse and clean the surface of the filter screen 12 after scraping and cleaning, so that the impurities adhered to the surface of the filter screen 12 can fall off completely, thereby further improving the cleanliness of the surface of the filter screen 12.

[0027] like Figure 5 As shown, the inner wall of the installation box 27 is fixedly connected to the first magnetic block 4; the side wall of one side of the cleaning plate 28 is fixedly connected to the second magnetic block 41; the first magnetic block 4 and the second magnetic block 41 are both arranged on the inner side of the multiple groups of spring columns 29; when working: the first magnetic block 4 and the second magnetic block 41 repel each other due to the magnetic force, thereby pushing the end of the cleaning plate 28 to fit more closely with the surface of the filter screen 12, so that the end of the cleaning plate 28 is more effective in cleaning impurities adhered to the surface of the filter screen 12.

[0028] like Figure 5 As shown, a pair of slide grooves 5 are provided on the inner side wall of the filter box 11; slide posts 51 are slidably connected to the inner sides of the slide grooves 5; the slide posts 51 are connected to one side wall of the installation box 27 at one end close to the filter screen 12; during operation: since the slide posts 51 are connected to the installation box 27, during the movement of the installation box 27, the slide grooves 5 and the slide posts 51 cooperate with each other, thereby improving the overall stability of the installation box 27 and the cleaning plate 28 during movement.

[0029] like Figure 4 As shown, a scraper 6 is fixedly connected to the side wall of the installation box 27 close to the servo motor 2; the bottom of the scraper 6 fits with the inner bottom of the filter box 11; when working: the electric push rod 112 is started to pull the baffle 111 to move backward, so that the baffle 111 no longer closes the slag discharge port 110. Since the installation box 27 and the scraper 6 are connected to each other, the scraper 6 moves along with the movement of the installation box 27. During the movement of the scraper 6, the waste water and impurities dropped from the inner bottom of the filter box 11 can be scraped and cleaned, that is, the scraped and cleaned waste water and impurities are directly discharged to the outside through the slag discharge port 110, thereby improving the cleanliness of the inner bottom of the filter box 11.

[0030] like Figure 5 As shown, the cleaning brush 7 is fixedly connected to one end of the slider 26 close to the servo motor 2; during operation: since the slider 26 and the cleaning brush 7 are connected to each other, the dust and impurities adhering to the surface of the screw rod 24 can be cleaned during the movement of the slider 26, thereby improving the cleanliness of the surface of the screw rod 24.

[0031] Working principle: the exhaust gas enters the filter box 11 through the air inlet pipe 113, and the large particle impurities contained in the exhaust gas can be filtered for the first time through the filter screen 12. At this time, the suction pump 14 is started to make the exhaust gas after the first filtration in the filter box 11 enter the first fixed box 16 through the first connecting pipe 13 and the second connecting pipe 15. Because water is stored in the first fixed box 16, and the height of the water is lower than the end of the third connecting pipe 18, the water in the first fixed box 16 can absorb and filter the unpleasant gas contained in the exhaust gas. The exhaust gas after absorption and filtration can enter the second fixed box 17 through the third connecting pipe 18, and the second fixed box 17 is provided with sodium hydroxide solution. When the exhaust gas enters the second fixed box 17, it can be absorbed and filtered again by the sodium hydroxide solution. Finally, the clean gas after filtering is discharged to the outside through the exhaust pipe 19, thereby reducing the irritating and unpleasant gas contained in the exhaust gas. If the exhaust gas is directly discharged into the external environment, it is easy to cause serious pollution to the environment by the exhaust gas, thereby improving the overall quality of the external environment; because a pair of pulleys 21 are both provided with a transmission belt 22 on the inner side, the servo motor 2 is started, and the pair of pulleys 21 can be driven to rotate through the cooperation between the pair of pulleys 21 and the transmission belt 22. Because the pulley 21 and the screw rod 24 are connected to each other, the pulley 21 can drive the screw rod 24 to rotate during the rotation of the pulley 21. The rod 24 rotates inside the sleeve 23. Since the screw rod 24 and the slider 26 are threadedly connected, and the slider 26 and the installation box 27 are connected to each other, that is, during the rotation of the screw rod 24, the slider 26 and the installation box 27 are driven to move. During the movement of the installation box 27, multiple groups of spring columns 29 push the cleaning plate 28 to move left and right inside the installation box 27. When the spring columns 29 push the end of the cleaning plate 28 to move to fit the surface of the filter screen 12, the large particles of impurities adhered to the surface of the filter screen 12 during filtering can be cleaned, thereby reducing the situation that the surface of the filter screen 12 is easily blocked due to the large number of large particles of impurities adhered to the surface of the filter screen 12, thereby improving the filter screen 12 when filtering exhaust gas. The overall patency is improved, and the cleanliness of the surface of the filter 12 is improved; water is added to the water tank 3 through the water inlet 31, and the water pump 33 is started, so that the water in the water tank 3 enters the fifth connecting pipe 34 through the fourth connecting pipe 32. At this time, the high-pressure nozzle 35 can rinse and clean the surface of the filter 12 after scraping and cleaning, so that the impurities adhering to the surface of the filter 12 are completely dropped, thereby further improving the cleanliness of the surface of the filter 12; the first magnetic block 4 and the second magnetic block 41 repel each other due to magnetic force, thereby pushing the end of the cleaning plate 28 to fit the surface of the filter 12 more closely, so that the end of the cleaning plate 28 is more effective in cleaning the impurities adhering to the surface of the filter 12;Because the slide post 51 and the installation box 27 are connected to each other, the slide slot 5 and the slide post 51 cooperate with each other during the movement of the installation box 27, thereby improving the overall stability of the installation box 27 and the cleaning plate 28 during movement; the electric push rod 112 is started to pull the baffle 111 to move backward, so that the baffle 111 no longer closes the slag discharge port 110. Because the installation box 27 and the scraper 6 are connected to each other, the scraper 6 moves along during the movement of the installation box 27. During the movement of the scraper 6, the waste water and impurities dropped from the bottom of the inner side of the filter box 11 can be scraped and cleaned, that is, the scraped and cleaned waste water and impurities are directly discharged to the outside through the slag discharge port 110, thereby improving the cleanliness of the bottom of the inner side of the filter box 11; because the slider 26 and the cleaning brush 7 are connected to each other, the dust and impurities adhering to the surface of the screw rod 24 can be cleaned during the movement of the slider 26, thereby improving the cleanliness of the surface of the screw rod 24. ;
