There are a plurality of blowing pipes 6, each of which extends out of the dust collector housing 1 and is connected to a pulse valve 8 through a blowing connecting pipe 7. The pulse valves 8 are evenly distributed on the air bag 9, and a safety valve 10 is also installed on the air bag 9. The air bag 9 is fixed on the left side of the outside of the dust collector housing 1. A pulse valve controller 11 and an air-water separator 12 are also installed on the left side of the outside of the dust collector housing 1. The pulse valve controller 11 is connected to the pulse valve 8 through a pulse control cable 17, and the air-water separator 12 is connected to the air bag 9 through an air inlet pipe 18; two hydraulic fans 13 are installed on the top of the dust collector housing 1, and the hydraulic fans 13 are located above the clean air chamber; an inspection door 14 is provided on the front of the dust collector housing 1, and an ash bin 15 at the bottom of the dust collector housing 1 is sleeved with an ash unloading rubber sleeve 16 at the bottom.

[0018] It is worth noting that the inspection door 14 is connected to the front part of the dust collector housing 1 by a hinge, and the filter element 4 and the filter element adjustment frame 5 are located on the inner side of the inspection door 14; there are four filter elements 4, and there are two filter element adjustment frames 5, and two filter elements 4 are fixed on each filter element adjustment frame 5, and the filter element 4 is fixed to the filter element adjustment frame 5 by a bottom plate hand wheel. The installation and removal of the filter element 4 can be achieved by adjusting the bottom plate hand wheel, which improves the replacement and maintenance efficiency, reduces the workload of workers, and facilitates personnel operation.

A plurality of lifting ears 20 are arranged above the dust collector housing 1 to facilitate overall lifting; a guardrail 21 is installed around the hydraulic fan 13 to protect the hydraulic fan 13.

[0020] The working principle of this specific embodiment is as follows: when the dust collector is in operation, the hydraulic fan 13 provides air volume by connecting to the hydraulic pump. The hydraulic fan 13 generates negative pressure when it works, so that the external polluted air passes through the air inlet pipe flange 3 and the air inlet box 2 into the polluted air chamber in the dust collector housing 1. The large particles in the polluted air are blocked by the filter element 4 and adsorbed on the filter element 4. At the same time, the compressed air in the air bag 9 is controlled by the pulse valve 8 and blown out through the blow pipe 6, blowing the dust on the filter element 4 into the ash unloading rubber sleeve 16 at the bottom of the ash bin 15. The side ash baffle on the ash bin 15 can make the dust fall into the ash collecting drawer better and will not fall into the gap between the polluted air chamber body and the ash collecting drawer. The clean air filtered by the filter element 4 passes through the clean air chamber and is discharged from the air outlet through the hydraulic fan 13.

[0021] This specific implementation method can make better use of the limited space of the drilling rig, has a compact structure, smooth airflow during operation, high system stability, greatly extends the service life of the drilling rig's mechanical and electrical equipment, has high filtration efficiency, meets the use requirements of the drilling rig filtration, and has broad market application prospects.
