A limit block 405 is fixedly connected to the surface of the toothed plate 404, and a baffle 407 is fixedly connected to the side of the toothed plate 404 away from the inclined filter plate 402. By setting the rubber head 406, damage to the inclined filter plate 402 can be avoided as much as possible when it is struck. By setting the limit block 405 and the baffle 407, the stable installation of the toothed plate 404 can be ensured.

[0032] A mounting ring 408 is fixedly connected to the side of the outer casing 1 near the baffle 407, and a motor 409 is fixedly connected to the inner wall of the mounting ring 408. The mounting ring 408 allows the motor 409 to be connected to the outer casing 1. A rotating rod 410 is fixedly connected to the output end of the motor 409, and a gear 411 is fixedly connected to the end of the rotating rod 410 near the gear plate 404. The gear 411 meshes with the gear plate 404. By using the motor 409, the rotation of the rotating rod 410 and the gear 411 can be controlled, and the rotation of the gear 411 can drive the gear plate 404 to move.

[0033] Reference Figure 1 and Figure 2 as well as Figure 4 As shown, specifically, the collecting device 5 includes a connecting cylinder 51, which is fixedly connected to the lower surface of the mounting cylinder 401. The connecting cylinder 51 and the mounting cylinder 401 are in communication. Two positioning plates 53 are fixedly connected to the side of the connecting cylinder 51. A collecting box 52 is installed on the side of the two positioning plates 53 away from the suction pump 2. The collecting box 52 is slidably connected to the inner wall of the outer casing 1. By setting the connecting cylinder 51 and the collecting box 52, it is convenient to collect the impurities accumulated on the inner wall of the mounting cylinder 401. By setting the positioning plates 53, the collecting box 52 can be positioned during installation.

[0034] A cleaning plate 56 is slidably connected to the inner wall of the mounting cylinder 401. The vertical cross-section of the cleaning plate 56 is triangular. The cleaning plate 56 fits tightly against the inclined filter plate 402. A mounting plate 54 is fixedly connected to the side of the outer shell 1. A pull rod 55 is slidably connected to the inner wall of the mounting plate 54 and is fixedly connected to the cleaning plate 56. By setting the mounting plate 54, the pull rod 55 can be connected to the outer shell 1. By setting the pull rod 55, the movement of the cleaning plate 56 can be easily controlled.

By setting the pull plate 57, the spring 58 can be easily installed, and the movement of the pull rod 55 can be easily controlled. By setting the spring 58, the position of the pull rod 55 can be limited.

[0035] Working principle: When using the CO detection device to detect CO concentration, the air pump 2 inside the outer shell 1 is activated, thereby drawing air from the coal mill environment into the outer shell 1. At this time, the CO detection sensor 3 inside the outer shell 1 completes the detection of CO concentration and feedback of the result. During the use of the CO detection device, the starting motor 409 drives the rotating rod 410 and gear 411 to rotate reciprocally. The rotation of gear 411 causes the toothed plate 404 to slide on the inner wall of the fixed block 403, thereby controlling the rubber head 406 to move back and forth towards the inclined filter plate 402, knocking on the inclined filter plate 402 and causing the dust on its surface to fall onto the inner wall of the mounting cylinder 401, thus cleaning the inclined filter plate 402. By setting the limit block 405 and the baffle 407, a stable connection between the toothed plate 404 and the fixed block 403 can be ensured. By setting the mounting ring 408, the motor 409 can be connected to the outer casing 1. By setting the cleaning device 4, the inclined filter plate 402 can be cleaned during the CO concentration detection process, thereby minimizing the impact of impurities on the CO concentration detection. The inclined filter plate 402 facilitates the cleaning of the filter plate and improves the cleaning effect.

[0036] When it is necessary to clean the inside of the mounting cylinder 401, pull the pull plate 57 to drive the pull rod 55 to slide on the inner wall of the mounting plate 54. The pull rod 55 then pulls the cleaning plate 56 to move closer to the connecting cylinder 51. The cleaning plate 56 pushes the impurities inside the mounting cylinder 401 through the connecting cylinder 51 into the collection box 52. Then, release the pull plate 57. Under the action of the spring 58, the cleaning plate 56 moves closer to the inclined filter plate 402, and the collection box 52 moves away from the outer shell 1. After cleaning the collection box 52, move the collection box 52 closer to the positioning plate 53. After the installation of the collection box 52 is completed, the impurities accumulated inside the mounting cylinder 401 can be easily collected by setting the collection device 5, thereby facilitating the cleaning of the inside of the mounting cylinder 401 and improving the cleaning efficiency of the impurities inside the mounting cylinder 401.
