[0021] An inlet pipe 2 is provided at the top of the dust removal pipe 1, an outlet pipe 3 is provided at one end of the bottom of the dust removal pipe 1, and a storage tank 7 is slidably connected inside the bottom of the dust removal pipe 1. Through the arrangement of the inlet pipe 2 and the outlet pipe 3, the exhaust gas passes through the inlet pipe 2 and is discharged from the outlet pipe 3, and the exhaust gas can be filtered by the dust removal filter plate 5;

[0022] A rectangular sliding plate 12 is fixed on the top of the vertical sealing plate 11, and a vertical slide groove is provided inside the vertical rectangular box 8. The rectangular sliding plate 12 is located inside the vertical slide groove and is slidably connected with the vertical rectangular box 8 through the vertical slide groove. Through the setting of the vertical slide groove, the rectangular sliding plate 12 can slide inside the vertical rectangular box 8;

[0023] The lifting mechanism includes a second drive motor 9, the second drive motor 9 is fixed by bolts on the top of the vertical rectangular box 8, and a vertical threaded rod 13 is fixed on the output end of the second drive motor 9. The vertical threaded rod 13 penetrates the interior of the rectangular sliding plate 12 and the vertical sealing plate 11 and is threadedly connected to the rectangular sliding plate 12 and the vertical sealing plate 11 respectively, so that the operation of the second drive motor 9 enables the vertical threaded rod 13 to rotate, and the rotation of the vertical threaded rod 13 enables the rectangular sliding plate 12 and the vertical sealing plate 11 to slide vertically, and through the sliding of the vertical sealing plate 11, the vertical sealing plate 11 can separate the dust removal duct 1 from the interior of the side rectangular box 14;

[0024] The moving mechanism includes a hydraulic cylinder 10, and the hydraulic cylinder 10 is fixed at both ends of the side rectangular box 14. A vertical lifting plate 15 is fixed to the output end of the hydraulic cylinder 10, and a U-shaped fixing frame 17 is fixed to one side of the vertical lifting plate 15. A third driving motor 18 is fixed to one end of the U-shaped fixing frame 17 by bolts, and a first transverse threaded rod 19 is fixed to the output end of the third driving motor 18. A second transverse threaded rod 20 is fixed to the end of the first transverse threaded rod 19 away from the third driving motor 18. The thread rotation direction of the first transverse threaded rod 19 is opposite to that of the second transverse threaded rod 20. The outer sides of the first transverse threaded rod 19 and the second transverse threaded rod 20 are both threadedly connected with a transverse sliding column 22. The end of the transverse sliding column 22 close to the vertical scraper 16 is rotatably connected to an oblique rotating column 23 through a pin shaft. The oblique rotating column 23 is close to one end of the vertical scraper 16 and is rotatably connected to the vertical scraper 16 through a pin shaft.

[0025] The connection between the first transverse threaded rod 19 and the second transverse threaded rod 20 is rotatably connected with a partition plate through a bearing, and the partition plate is fixedly connected to the U-shaped fixing frame 17. The setting of the partition plate makes the connection between the first transverse threaded rod 19 and the second transverse threaded rod 20 more stable, preventing the connection between the first transverse threaded rod 19 and the second transverse threaded rod 20 from bending, so that the first transverse threaded rod 19 and the second transverse threaded rod 20 can better rotate synchronously;

[0026] A transverse polished rod 21 is fixed inside the U-shaped fixing frame 17. The transverse polished rod 21 passes through the interior of the transverse sliding column 22 and is slidably connected to the transverse sliding column 22, so that the transverse sliding column 22 can slide outside the transverse polished rod 21, so that the movement of the transverse sliding column 22 can be guided by the transverse polished rod 21.

[0027] Here, the operation of the third drive motor 18 enables the first transverse threaded rod 19 and the second transverse threaded rod 20 to rotate, and the rotation of the first transverse threaded rod 19 and the second transverse threaded rod 20 enables the transverse sliding column 22 to slide on the outside of the transverse light rod 21, and the sliding of the transverse sliding column 22 enables the vertical scraper 16 to move toward the surface of the dust filter plate 5 through the oblique rotating column 23, so that the vertical scraper 16 and the surface of the dust filter plate 5 are in contact with each other, and the operation of the hydraulic cylinder 10 enables the vertical scraper 16 to be lifted and lowered vertically, so that the vertical scraper 16 can vertically remove dust from the surface of the dust filter plate 5 to prevent the surface of the dust filter plate 5 from being blocked by dust.

[0028] Working principle: Through the setting of the inlet pipe 2 and the outlet pipe 3, the exhaust gas passes through the inlet pipe 2 and is discharged from the outlet pipe 3, and the exhaust gas can be filtered by the dust removal filter plate 5.

[0029] The second driving motor 9 is operated to rotate the vertical threaded rod 13, and the rotation of the vertical threaded rod 13 enables the rectangular sliding plate 12 and the vertical sealing plate 11 to slide vertically. The vertical sealing plate 11 can separate the dust removal duct 1 from the inside of the side rectangular box 14 through the sliding of the vertical sealing plate 11;

[0030] The operation of the third drive motor 18 enables the first transverse threaded rod 19 and the second transverse threaded rod 20 to rotate. The rotation of the first transverse threaded rod 19 and the second transverse threaded rod 20 enables the transverse sliding column 22 to slide on the outside of the transverse light rod 21. The sliding of the transverse sliding column 22 enables the vertical scraper 16 to move toward the surface of the dust filter plate 5 through the oblique rotating column 23, so that the vertical scraper 16 and the surface of the dust filter plate 5 are in contact with each other. The operation of the hydraulic cylinder 10 enables the vertical scraper 16 to be lifted and lowered vertically, so that the vertical scraper 16 can vertically remove dust from the surface of the dust filter plate 5 to prevent the surface of the dust filter plate 5 from being blocked by dust.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
