Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

Embodiment 1, please refer to Figures 1-5, the utility model provides a technical solution: a dust filtering device, including a body 1, an air inlet pipe 2, a fan 3, a connecting pipe 4, a partition 5, a filter bag 6, a cleaning pipe 7, a filter box 11, a liquid collecting box 18 and a sealing door 20, the bottom of the body 1 is provided with an air inlet pipe 2 at one side position, the top of the body 1 is provided with a fan 3, a connecting pipe 4 is installed between the fan 3 and the body 1, the inside of the body 1 is provided with a partition 5, filter bags 6 are installed between the partitions 5, the inside of the body 1 is provided with a cleaning pipe 7 above the filter bag 6, one end of the cleaning pipe 7 passes through the rear surface of the body 1, a valve 8 is installed on the surface of the cleaning pipe 7, by setting the valve 8, the effect of controlling the size of the water flow is achieved, the bottom of the cleaning pipe 7 is provided with a ring head 9, and nozzles 10 are installed all around the ring head 9.

Please refer to Figures 1-8. A filter box 11 is provided inside the body 1 below the filter bag 6, and a filter screen 12 is installed between the filter boxes 11. An inclined plate 13 is fixedly installed at the bottom of the filter box 11. A notch is provided on the surface of the filter box 11 on one side of the inclined plate 13. An outer sealing frame 14 is provided on one side of the filter box 11. A handle 17 is fixedly installed on the surface of the outer sealing frame 14. The handle 17 is provided to facilitate people to pull the outer sealing frame 14. Shrapnel 15 is provided on both sides of the outer sealing frame 14. Blocks 16 are provided on both sides of the body 1 near the shrapnel 15. A liquid collecting box 18 is also provided at the bottom of the body 1. A sealing door 20 is installed on the surface of the body 1. A transparent window 19 is provided on the surface of the body 1 near the filter bag 6. The transparent window 19 allows people to check whether there are too many solid dust impurities accumulated on the filter screen 12.

Embodiment 2, please refer to FIG. 1 , an auxiliary device is provided at the bottom of the machine body 1 , and the auxiliary device includes an inclined frame 21 , which is fixedly mounted at the bottom of the machine body 1 at one side, and a conveying roller 22 is rotatably connected between the inclined frames 21 .

Please refer to FIG. 1 , the conveying rollers 22 are evenly distributed on the inclined frame 21 . By providing the rotatable conveying rollers 22 , the liquid collecting box 18 can be quickly moved from the inclined frame 21 .

Working principle: In actual use, by setting the body 1, air intake pipe 2, fan 3, connecting pipe 4, partition 5, filter bag 6, cleaning pipe 7, ring head 9, nozzle 10, filter box 11, filter screen 12, inclined plate 13, outer sealing frame 14, spring 15, block 16, liquid collecting box 18 and sealing door 20, firstly, the air intake pipe 2 is connected to the ore crusher through the external pipeline, and then the fan 3 is started. The fan 3 sucks the dust generated by the ore crusher during operation from the air intake pipe 2 into the body 1 through the connecting pipe 4, and then the filter bag 6 on the partition 5 will filter the dust, so that Clean air can be discharged from the top of the machine body 1, which has the effect of filtering dust. When it is necessary to clean the dust attached to the filter bag 6, the external water pipe is connected to the cleaning pipe 7, and then water is sent to the cleaning pipe 7 through the external water pipe. The water flows to the ring head 9 through the cleaning pipe 7, and finally sprayed out from the nozzles 10 around the ring head 9. At this time, the dust on the filter bag 6 will be washed by the water and flow into the filter box 11 along the water flow. At this time, the filter screen 12 on the filter box 11 will intercept the solid dust impurities, and the water used to clean the filter bag 6 flows to the inclined plate 13 through the filter screen 12. Finally, it flows out from the notch on one side of the filter box 11 along the surface of the inclined plate 13 to the liquid collecting box 18, which plays the role of recycling water. Since the dust impurities in the water are filtered by the filter screen 12, the recycled water can be stored and used for the next cleaning of the filter bag 6. When it is necessary to clean the dust impurities on the filter screen 12, it is only necessary to pull the handle 17 to separate the spring piece 15 and the block 16 from each other. At this time, the filter box 11 can be smoothly drawn out from the machine body 1, which plays the role of disassembling the filter box 11. When the filter box 11 needs to be installed, it only needs to be put back into the machine body 1. The outer sealing frame 14 blocks the gap between the machine body 1 and the filter box 11, thereby preventing water from seeping out of the gap. In actual use, by setting an auxiliary device and installing an inclined frame 21 on one side of the machine body 1, people can drag the liquid collecting box 18 to the conveying roller 22 between the inclined frames 21, so that the liquid collecting box 18 can be quickly moved to the ground, making it convenient for people to remove the liquid collecting box 18 from the machine body 1, and avoiding the situation where there is a certain weight of water in the liquid collecting box 18, which makes it inconvenient for people to lift it.

The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
