[0019] The dust reduction component includes a sleeve 18 fixedly mounted on the upper outer side of the ventilator 11, a chuck 29 is fixedly installed on the inner side of the top tank 1 and located above the sleeve 18, the sleeve 18 and the chuck 29 are rotatably matched, and connecting blocks 30 are fixedly installed on both sides of the bottom of the chuck 29, and an annular tube 34 is installed together on the inner sides of the two connecting blocks 30. The inner sides of the annular tube 34 are connected and connected with nozzles 31 at equal distances along the circumferential direction. The chuck 29 and the connecting block 30 can set the annular tube 34 above the inner side of the top tank 1 to treat the dust in the gas by spraying. The nozzle 31 is an atomizing nozzle 31, and a water inlet pipe 39 is installed on one end of the inner side of the annular tube 34. The water inlet pipe 39 extends to the outside of the top tank 1 away from the end of the annular tube 34.

[0020] The filter assembly includes a bucket net 13 fixedly installed in the middle of the inner side of the connecting pipe 6.

[0021] The dust rolling assembly includes a second ring 20 fixedly mounted on the outside of the ventilator 11 and located below the sleeve 18, wherein guide rods 21 are inserted into the inside of the second ring 20 at equal intervals along the circumferential direction, and a sleeve rod 24 is connected to the outside of the guide rod 21 through an elastic component, and a resist cylinder 28 is rotatably mounted on the outside and below of the sleeve rod 24. Under the connection of the sleeve rod 24, the resist cylinder 28 is driven by the rotation of the second ring 20, so that the resist cylinder 28 can roll and fit with the inner surface of the bucket screen 25.

[0022] The elastic component includes a spring 35 sleeved on the outside of the sleeve rod 24, and a sleeve 22 is slidably sleeved on the outside of the guide rod 21 and located at one end of the spring 35. One end of the sleeve rod 24 is vertically installed at the bottom of the outside of the sleeve 22. Under the sliding and squeezing of the spring 35 and the sleeve 22, the front end cylinder 28 can be more flexible and more adaptable to the bucket screen 25 when in use.

[0023] The rotating assembly includes a first ring 17 fixedly mounted on the outside of the ventilator 11 and located below the second ring 20. Sliders 23 are installed on the outside of the first ring 17 at equal distances in the circumferential direction. An annular groove 33 adapted for sliding of multiple slides 23 is opened on the upper inner side of the bottom tank 2. The sliding cooperation between the multiple slides 23 and the annular groove 33 can enhance the stability of the lower end of the ventilator 11 when it rotates.

[0024] The extrusion assembly includes a ring platform 15 fixedly mounted above the bucket screen 25, and elastic plates 38 are installed on the inner wall of the ring platform 15 at equal distances along the circumferential direction, and an elastic rope 26 is fixedly mounted on the bottom end of the elastic plate 38. Flexible balls 27 are installed on the outer side of the elastic rope 26 at equal distances along the vertical direction. The push tube 28 is in active contact with the corresponding flexible ball 27. The flexible ball 27 squeezes the sieve holes on the inner surface of the bucket screen 25 under the rolling of the push tube 28, thereby achieving the cleaning purpose. It should be specially noted that the diameter of the flexible ball 27 is larger than the diameter of the sieve holes of the bucket screen 25. Therefore, during the extrusion process, the edge of the flexible ball 27 contacts the sieve holes, and the curved surface protrusions of the flexible ball 27 can remove the blocked foreign matter, which can avoid the problem of the flexible ball 27 being stuck and passing through the sieve holes, thereby affecting the later cleaning.

[0025] A suction pipe 5 is installed on the upper inner side of the top tank 1 and at one end away from the air inlet pipe 8. A suction pump 4 is installed on the other end of the suction pipe 5 away from the top tank 1. The suction pump 4 can suck the treated gas above the inside of the top tank 1 by means of the suction pipe 5, thereby achieving the effect of drainage and exhaust. The upper end of the rotating shaft 9 passes through the top of the top tank 1 and a motor 3 is installed at the end. The motor 3 is fixedly installed on the top of the top tank 1. After the motor 3 is connected to the power supply, it can drive the rotating shaft 9 to rotate, thereby rotating the vent tube 11. Brackets 37 are installed on the outer wall of the bottom tank 2 at equal distances along the circumferential direction.

[0026] Working principle: When in use, the gas suction pipe of the underground gas is introduced into the air inlet pipe 8, and the gas inside the air inlet pipe 8 can enter the inside of the ventilation cylinder 11 through multiple air ports 12, and then the motor 3 is connected to the external power supply to drive the rotating shaft 9 and the fixed plate 10 to rotate, so as to cause the gas entering the ventilation cylinder 11 to rotate at a high speed, and the gas containing impurities flows downward by its own gravity, and then in the centrifugal process, the gas is transported to the outside of the ventilation cylinder 11 through multiple outlet pipes 19, and the gas gathers on the inner surface of the bucket screen 25, and the impurities are filtered by the bucket screen 25 to separate the impurities in the gas, and the gas becomes lighter and flows upward. At the same time, the annular pipe 34 can spray water mist through multiple groups of nozzles 31 on the top under the connection of the water inlet pipe 39 and the external water supply pipeline, so that the water mist is in full contact with the gas, and the gas is dusted during the flow process, thereby fully removing the gas. The impurities in the body are then sucked out by the suction pump 4 to drain the gas from the top, ensuring the fluidity of the gas and reducing the concentration of the gas during the treatment process. During the drainage process, the gas is separated again by the bucket net 13 for secondary separation, so as to fully purify the gas. The multiple scraper rods 32 also clean the impurities on the upper and lower surfaces of the bucket net 13 during the rotation process, so as to ensure the fluidity of the bucket net 13. Under the rotation of the sleeve 18 and the second ring 20, the lower outer side of the second ring 20 rolls and fits with the inner surface of the bucket screen 25 under the pressure of the elastic component. During the rolling process, the elastic rope 26 and the outer flexible ball 27 are squeezed, so that the flexible ball 27 will use the curved surface on the inner surface of the bucket screen 25 to squeeze the foreign matter in the sieve hole, so as to dredge the dust dropped by the spray, thereby maximizing the use of the bucket screen 25, thereby ensuring the continuous separation effect of the bucket screen 25.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
