[0043] See also Figure 1 and Fig.10As shown, the support column 2 includes a square shell 201 and a square column 202; the outer wall of the square column 202 is slidably connected to the inner wall of the square shell 201; the collecting pipe 3 is fixedly connected to the square column 202; a fixing plate 46 is fixedly connected to one side of the outer wall of the square column 202; a second threaded rod 47 is threadedly connected to one side of the outer wall of the square shell 201 through a sixth square plate, and one end of the outer wall of the second threaded rod 47 is rotatably connected to the bottom end of the outer wall of the fixing plate 46; the rotating shaft 12 is a telescopic structure, through which the support column 2 includes the square shell 201 and the square column 20 2. When the second threaded rod 47 rotates, since the second threaded rod 47 is threadedly connected to the sixth square plate, the rotation of the second threaded rod 47 drives the second threaded rod 47 to move up and down, so that the second threaded rod 47 drives the fixing plate 46 to move up and down, and the fixing plate 46 drives the square column 202 to move up and down, so that the square column 202 drives the collecting pipe 3 to move up and down, so that the device can adjust the height of the collecting pipe 3, and the height of the collecting pipe 3 can be adjusted according to the height of the exhaust gas discharge channel of the fireplace production workshop, making the device more practical and convenient.

[0044] When the present invention is in use, the collection pipe 3 is aligned with the exhaust gas discharge channel of the fireplace production workshop; at this time, the exhaust gas from the fireplace production workshop is discharged into the collection pipe 3, and at this time, the exhaust gas will flow from the circular rod 30 through the collection pipe 3 to the exhaust gas centrifugal mechanism 4 for centrifugal treatment, so that impurities such as oil mist and moisture in the exhaust gas are separated from the exhaust gas, and then the exhaust gas enters the activated carbon adsorption tower 6 through the connecting pipe 7. At this time, the activated carbon adsorption tower 6 adsorbs harmful substances in the exhaust gas on the surface of the activated carbon to achieve the purpose of purifying the exhaust gas. Finally, the purified exhaust gas in the activated carbon adsorption tower 6 is discharged to complete the exhaust gas treatment. When the exhaust gas enters the collection pipe 3, the exhaust gas will pass through the coarse filter 8 and the fine filter 9. At this time, the coarse filter 8 and the fine filter 9 will remove large particles of impurities in the exhaust gas. The filtration makes it more convenient for the waste gas to be subsequently treated. When the coarse filter 8 and the fine filter 9 filter the waste gas, the motor 10 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the first bevel gear 13 to rotate. Because the second bevel gear 14 is meshed with the first bevel gear 13, the first bevel gear 13 drives the rotating rod 11 to rotate through the second bevel gear 14, so that the rotating rod 11 drives the two groups of cleaning plates 15 to rotate, so that the two groups of cleaning plates 15 clean the coarse filter 8 and the fine filter 9 respectively, thereby solving the problem of impurities blocking the coarse filter 8 and the fine filter 9, so that the coarse filter 8 and the fine filter 9 do not need to be cleaned by the staff, thereby reducing the use of human resources. At the same time as filtering, the coarse filter 8 and the fine filter 9 are cleaned, so that the exhaust gas treatment effect and treatment efficiency of the coarse filter 8 and the fine filter 9 are better, and when the motor 10 drives the rotating shaft 12 to rotate, the rotation of the rotating shaft 12 drives the third gear 19 to rotate. Because the third gear 19 and the first annular rack 16 are meshed with each other, the rotation of the third gear 19 drives the first annular rack 16 to rotate, and the first annular rack 16 drives the centrifugal shell 18 to rotate, so that the centrifugal shell 18 can centrifugally treat the exhaust gas, and the cleaning of the cleaning plate 15 and the rotation of the centrifugal shell 18 are driven by a motor 10, so that the device can reduce energy consumption, thereby reducing the cost of exhaust gas treatment, making the device more competitive in the market, and when the cleaning plate 15 rotates The rotation of the cleaning plate 15 drives the pair of first rotating rods 22 to rotate. Because the outer wall ends of the pair of first rotating rods 22 outside the square through groove 21 are fixedly connected with the fourth gear 24, the pair of first rotating rods 22 drives the fourth gear 24 to rotate. Because the inner side wall of the collecting tube 3 is fixedly connected with a pair of second annular racks 25; the pair of second annular racks 25 and the multiple groups of fourth gears 24 are meshed with each other, so that when the fourth gear 24 rotates, it will rotate due to the fixed and stationary second annular rack 25, so that the rotation of the fourth gear 24 drives the first rotating rod 22 to rotate, and the first rotating rod 22 drives the auxiliary plate 23 to rotate, so that when the cleaning plate 15 cleans the coarse filter 8 and the fine filter 9, the multiple pairs of auxiliary plates 23 will also clean the coarse filter 8 and the fine filter 9 while rotating.Thereby, the cleaning efficiency and cleaning effect of the device for the coarse filter 8 and the fine filter 9 are improved, and when the auxiliary plate 23 rotates, the rotation of the auxiliary plate 23 will drive the second rotating rod 27 to rotate, because one end of the outer wall of the pair of second rotating rods 27 is fixedly connected to the sixth bevel gear 28 and one side of the inner wall of the square through groove 21 is fixedly connected to the pair of fifth bevel gears 26; when the second rotating rod 27 drives the sixth gear 36 to rotate, because the fifth gear and the sixth gear 36 are meshed with each other, and the fifth gear is in a fixed state and the sixth gear 36 is in a moving state, when the sixth gear 36 rotates, the sixth gear 36 will rotate due to the fifth gear in a fixed and stationary state, so that the rotation of the sixth gear 36 drives the second rotating rod 27 to rotate, and the second rotating rod 27 drives the circular shell 29 to rotate , so that the circular shell 29 drives the circular rod 30 and the vibration ball 31 to rotate. Because the circular rod 30 is connected to the circular shell 29 through the first spring, the vibration ball 31 has a telescopic effect, so that the circular rod 30 and the vibration ball 31 will knock on the coarse filter 8 and the fine filter 9 when they rotate, so that the vibration can accelerate the cleaning of impurities on the coarse filter 8 and the fine filter 9, so that the cleaning effect of the device is further improved, and when the rotating rod 11 rotates, the rotation of the rotating rod 11 drives the two groups of large fan blades 32 to rotate, so that the two groups of large fan blades 32 blow air, thereby accelerating the circulation of exhaust gas, so that the device has a better treatment effect on exhaust gas, and the rotation of the first rotating rod 22 also drives the multiple groups of small fan blades 33 to rotate, so that the multiple groups of small fan blades 33 cooperate with the rotation of the multiple groups of large fan blades 32. The large fan blades 32 and the small fan blades 33 rotate, so that the circulation and treatment of the exhaust gas are further improved, and when the large fan blades 32 and the small fan blades 33 rotate, the large fan blades 32 and the small fan blades 33 will also rotate through the flow of the exhaust gas, thereby reducing the energy consumption of the motor 10, so that the device further reduces the cost, thereby becoming more competitive in the market, and when the centrifugal shell 18 rotates, because the centrifugal shell 18 includes a lower shell 181 and an upper cover plate 182, because the upper cover plate 182 is limited by the circular rod 30 and the connecting pipe 7, the upper cover plate 182 does not rotate, and the lower shell 181 rotates. When the lower shell 181 rotates to centrifuge the exhaust gas, the rotation of the lower shell 181 drives the reciprocating rod 35 and the sixth gear 36 to rotate. Because the sixth gear 36 and the third annular rack 34 are mutually The third annular rack 34 is meshed, and the third annular rack 34 is fixed on the upper cover plate 182, so that the third annular rack 34 is in a stationary state, and the sixth gear 36 is in a moving state, so that the sixth gear 36 rotates when rotating, so that the rotation of the sixth gear 36 drives the reciprocating rod 35 to rotate, and the reciprocating rod 35 drives the cleaning block 37 to move up and down, so that the cleaning block 37 cleans the inner wall of the lower shell 181, so that impurities such as oil mist and moisture are not easy to adhere to the lower shell 181, thereby ensuring the environment of the lower shell 181, and when the cleaning block 37 cleans the inner wall of the lower shell 181, the recovery speed of impurities such as oil mist and moisture can be accelerated, so that the device can collect impurities such as oil mist and moisture more efficiently, and when the cleaning block 37 reciprocates up and down,The up and down reciprocating motion of the cleaning block 37 drives the scraper 40 to move up and down, and the scraper 40 drives the first round rod 39 to slide up and down in the first round shell 38. Because the scraper 40 is fixedly connected to the first round rod 39, the scraper 40 will not rotate, so that the centrifugal shell 18 rotates. When the scraper 40 does not rotate, the scraper 40 will clean the inner side wall of the centrifugal shell 18, thereby further improving the cleaning effect and cleaning efficiency of the centrifugal shell 18. Moreover, because the scraper 40 does not rotate, but the cleaning block 37 rotates, when the cleaning block 37 rotates, the scraper 40 0 will also clean the bottom end of the outer wall of the cleaning block 37, so that the cleaning block 37 is not easy to adhere to too much impurities, and because the outer wall of the scraper 40 is provided with a sliding groove 41 at one end; the inner wall of the sliding groove 41 is fixedly connected with a slider 42 through a second spring, so that when the scraper 40 scrapes and cleans the centrifugal shell 18, when one end of the outer wall of the scraper 40 is worn, the slider 42 will pop out under the elastic force of the second spring, so as to continue to clean the inner wall of the centrifugal shell 18, so that the cleaning efficiency and cleaning effect of the centrifugal shell 18 are guaranteed. When the first threaded rod 45 is rotated, because the first threaded rod 45 is threadedly connected to the connecting block 44, the rotation of the first threaded rod 45 drives the connecting block 44 to slide up and down on one side of the outer wall of the connecting plate 43, so that the connecting block 44 drives the upper cover plate 182 to move. At this time, the upper cover plate 182 is opened, so that the staff can clean or repair the inner wall of the centrifugal shell 18 or replace parts, etc., so that the centrifugal shell 18 is more convenient for the staff to detect and repair. When the second threaded rod 47 is rotated, because the second threaded rod 47 is threadedly connected to the sixth square plate, the rotation of the second threaded rod 47 drives the second threaded rod 47 to move up and down, so that the second threaded rod 47 drives the fixing plate 46 to move up and down, so that the fixing plate 46 drives the square column 202 to move up and down, so that the square column 202 drives the collecting pipe 3 to move up and down, so that the device can adjust the height of the collecting pipe 3, so that the collecting pipe 3 can be adjusted according to the height of the exhaust gas discharge channel of the fireplace production workshop, so that the device is more practical and convenient.
