[0022] The anti-blocking component 2 includes a first motor 203. The top of the first motor 203 is fixedly connected to the bottom of the housing 1 by bolts. The rotating shaft of the first motor 203 penetrates into the inner cavity of the housing 1 and is fixedly connected to a rotating rod 204. The top end of the rotating rod 204 penetrates to the top of the filter screen plate 11. A connecting rod 202 is fixedly connected to the surface of the rotating rod 204. One end of the connecting rod 202 away from the rotating rod 204 is fixedly connected to a first cleaning brush 201. By providing the connecting rod 202, the first cleaning brush 201 can be supported. When the rotating rod 204 rotates, the first cleaning brush 201 can rotate, thereby cleaning the filter screen plate 11;

[0023] The dust-proof component 7 includes a fan 701. The right side of the fan 701 is fixedly connected to the left side of the dust storage box 8 by bolts. The air inlet end of the fan 701 penetrates into the inner cavity of the dust storage box 8. The bottom of the dust storage box 8 is fixedly communicated with a suction pipe 703. The bottom end of the suction pipe 703 penetrates into the inner cavity of the housing 1 and is fixedly connected to a suction hood 704. A mesh cover 702 is fixedly connected to the left side of the inner cavity of the dust storage box 8. By providing the mesh cover 702, the fan 701 can be protected to prevent dust entering the dust storage box 8 from entering the interior through the air inlet end of the fan 701 and affecting the fan 701;

[0024] The moving component 9 includes a second motor 903. The front side of the second motor 903 is fixedly connected to the back of the housing 1 by bolts. The rotating shaft of the second motor 903 penetrates into the inner cavity of the housing 1. A support plate is fixedly connected to the inner cavity of the housing 1. The back of the support plate is movably connected to a short rod 904 by a bearing. Fixed sleeves of gears 902 are respectively provided at the front end of the rotating shaft of the second motor 903 and the rear end of the short rod 904. A toothed plate 901 is fixedly connected to the bottom of the filter basket 6. The toothed plate 901 and the gears 902 mesh with each other. By providing the short rod 904, the front gear 902 can be supported so that the front gear 902 can rotate;

[0025] A deflector 10 is fixedly connected to the top of the inner cavity of the housing 1. Support legs 15 are fixedly connected to the bottom of the housing 1.

[0027] During use, an external controller is connected. Pulverized coal to be filtered is poured into the housing 1 through the feeding pipe and thus falls into the filtering basket 6. The rotation of the shaft of the second motor 903 drives the rear gear 902 to rotate. Through the toothed plate 901, the filtering basket 6 moves left and right. When the filtering basket 6 moves, the front gear 902 is driven to rotate by the short rod 904, so that the filtering basket 6 can move stably, thereby filtering the pulverized coal and enabling the pulverized coal to quickly fall onto the filter mesh plate 11. At the same time, the fan 701 operates to suck air at the air inlet end. Through the dust suction pipe 703 and the dust suction hood 704, the dust generated during filtering is sucked into the dust storage box 8 to prevent the dust from flowing in the air. When the filtering basket 6 becomes blocked, the electric telescopic rod 3 extends to drive the second cleaning brush 5 to move, thereby cleaning the filtering basket 6 and preventing the filtering basket 6 from being blocked. Then, the pulverized coal is secondarily filtered through the filter mesh plate 11 to make the filtering of the pulverized coal cleaner. When the filter mesh plate 11 becomes blocked, the rotation of the shaft of the first motor 203 drives the rotating rod 204 to rotate. Through the connecting rod 202, the first cleaning brush 201 is rotated to clean the surface of the filter mesh plate 11 and prevent the filter mesh plate 11 from being blocked.

[0028] In summary, the pulverized coal filter for coal mine processing with a dust-proof structure, through the cooperation of the housing 1, the anti-blocking component 2, the electric telescopic rod 3, the support rod 4, the second cleaning brush 5, the filtering basket 6, the dust-proof component 7, the dust storage box 8, the moving component 9, the filter mesh plate 11 and the spring 12, solves the problems of not having a dust-proof function and not having an anti-blocking function.
