[0036] Combined with attachment Figure 1-3, a dust removal mechanism for mining, which includes a filter cartridge 1, an air inlet channel 2 is connected to one side of the bottom of the filter cartridge 1, and the air inlet channel 2 requires an external dust removal auxiliary equipment such as an exhaust fan, mainly for drawing the dust-laden gas into the filter cartridge 1, the top of the filter cartridge 1 is connected to an exhaust port 3, the top of the filter cartridge 1 is connected to an air collecting hood pipe 30 that matches the exhaust port 3, and the air collecting hood pipe 30 is connected to a one-way valve 31 to prevent the gas from circulating in reverse. The bottom of the filter cartridge 1 is connected to a sand collecting hopper 38, the top of the filter cartridge 1 is connected to a top support ring frame 4, and the middle of the top support ring frame 4 is connected to an air supply fan 29 that is connected to the inside of the filter cloth cover 8. The air supply fan 29 can cooperate to draw the gas upward, so that the filtered gas can be discharged through the exhaust port 3 and the air collecting hood pipe 30.

[0037] Combined with attachment Figure 3-7The bottom of the filter cartridge 1 is connected to a bottom support ring frame 6, the bottom of the top support ring frame 4 is connected to an upper cloth cover clamping mechanism 5, the top of the bottom support ring frame 6 is connected to a lower cloth cover clamping mechanism 7 which can be adjusted up and down, and a filter cloth cover 8 is clamped between the upper cloth cover clamping mechanism 5 and the lower cloth cover clamping mechanism 7. In actual operation, the filter cloth cover 8 needs to be tightened as much as possible through the upper cloth cover clamping mechanism 5 and the lower cloth cover clamping mechanism 7, so that dust filtering operations can be carried out over a large area. The outer side of the bottom of the structure 5 and the outer side of the top of the lower cloth cover clamping mechanism 7 are connected with an outer fixed ring frame 9, an elastic ring groove 12 is provided in the outer fixed ring frame 9, and an elastic ring plate 14 is provided in the elastic ring groove 12. The inner side of the elastic ring plate 14 is connected with a plurality of springs 13, and the outer side of the elastic ring plate 14 is connected with a clamping ring plate 10 for clamping the filter cloth cover 8. The clamping ring plate 10 extends to the outside and is connected with a first clamping rubber 15. The upper cloth cover clamping mechanism 5 and the lower cloth cover clamping mechanism 7 are connected. A ring groove 36 is provided between the outer fixed ring frame 9, and the ring groove 36 is connected to a plurality of fixing blocks 37 for fixing the upper cloth cover clamping mechanism 5 and the lower cloth cover clamping mechanism 7 to the outer fixed ring frame 9 on the side away from the clamping ring plate 10. The upper cloth cover clamping mechanism 5 and the lower cloth cover clamping mechanism 7 are threadedly connected to the inner side with a plurality of clamping bolts 11, and the clamping bolts 11 extend into the ring groove 36 and are connected to a clamping plate 16. The outer side of the clamping plate 16 is connected to a second clamping rubber 17. When the filter cloth cover 8 is actually installed That is, first press down the clamping ring plate 10 of the upper cloth cover clamping mechanism 5, and then insert the filter cloth cover 8 into the ring groove 36. After inserting it to a suitable length, multiple springs 13 cooperate with the elastic ring plate 14 to extend the clamping ring plate 10 and the first clamping rubber 15 to clamp the upper end of the filter cloth cover 8, and then multiple clamping bolts 11 cooperate with the clamping plate 16 and the second clamping rubber 17 to perform further clamping operations, thereby ensuring that the filter cloth cover 8 is firmly clamped. The same operation is performed for the lower cloth cover clamping mechanism 7 to clamp the lower end of the filter cloth cover 8.

[0038] Combined with attachment Figure 3-7, the bottom support ring frame 6 is threadedly connected with an adjusting screw 18 on both sides, and the bottom of the lower cloth cover clamping mechanism 7 is provided with a through hole 21 on both sides that matches the adjusting screw 18, and the lower cloth cover clamping mechanism 7 is provided with a groove 22 on both sides inside the through hole 21.

After the upper cloth cover clamping mechanism 5 and the lower cloth cover clamping mechanism 7 clamp the filter cloth cover 8, the height of the lower cloth cover clamping mechanism 7 can be adjusted by rotating the adjusting screw 18 on both sides, so that the filter cloth cover can be further tightened. The diameter of the through hole 21 is larger than the diameter of the adjusting screw 18. The diameter of the groove 22 is larger than the diameter of the support disc 23. This diameter setting allows one side to be adjusted before the other side is adjusted, thereby eliminating the need for synchronous rotation of the adjustment screws 18 on both sides. If further adjustment stability is required, multiple adjustment screws 18 can be provided. Multiple adjustment screws 18 can ensure the highly stable adjustment operation of the lower cloth cover clamping mechanism 7. The bottom of the lower cloth cover clamping mechanism 7 is connected to a first sealing door 19 that passes through the bottom support ring frame 6, and the bottom of one side of the filter cartridge 1 is connected to a second sealing door 20. The filter cloth cover can be replaced and maintained through the first sealing door 19 and the second sealing door 20.

[0039] The bottom of the sand collecting hopper 38 is connected to a sand discharge pipe 24, and the bottom of the sand discharge pipe 24 is connected to an auger feeder 25. The bottom of the filter cartridge 1 is connected to a material level sensor 26 electrically connected to the auger feeder 25. The outside of the auger feeder 25 is connected to a collecting pipe 27, and the collecting pipe 27 is connected to an electric control valve 28. The material level of the sand collecting hopper 38 is sensed by the material level sensor 26. The material level sensor 26 can be an infrared sensor. When the dust and sand level reaches the position of the material level sensor 26, the auger feeder 25 and the electric control valve 28 are started synchronously to discharge dust and sand regularly.

[0040] The top support ring frame 4 is connected to both sides of the top with a vibration motor 32, and the bottom power end of the vibration motor 32 is connected to a rotating shaft 33 extending to the outside of the filter cloth cover 8, and the rotating shaft 33 is connected to a vibration protrusion 34 that cooperates with the filter cloth cover 8. The top support ring frame 4 and the bottom support ring frame 6 are both connected to support bearings 35 that cooperate with the rotating shaft 33. By starting the vibration motor 32 to drive the rotating shaft 33 to rotate, the filter cloth cover 8 is hit with multiple vibration protrusions 34. Because there is no supporting mesh cylinder on the inside of the filter cloth cover 8, the damage caused by vibration can be reduced, making it more convenient to regularly vibrate and clean the dust attached to the outside of the filter cloth cover 8.

[0041] The above description of the present invention and its embodiments is non-limiting, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the invention, without creatively designing a structure and embodiment similar to the technical solution, they shall fall within the scope of protection of the present invention.
