[0023] Specifically, the centrifugal fan 2 is started to draw the oil into the interior of the bellows 11. When the oil runs toward the centrifugal fan 2, it will pass through the first-level static purification module 7 and the dynamic purification module 8. The centrifugal force generated by the rotation of the centrifugal fan 2 is used to radially throw the oil mist medium in the exhaust gas from the center, and the oil guide groove is set inside the equipment, and the oil is discharged to the bottom and into the interior of the oil collecting pan 18. When passing through the second-level static purification module 4, the centrifugal force generated by the rotation of the centrifugal fan 2 is used. At this time, the inertial force direction of the particulate matter is changed through the fibers of the filter, or the jet flow is forced to change direction multiple times, so that the particulate matter can be adhered to the deflector 6, thereby achieving the effect of filtering the particulate matter and improving the treatment effect of the oil mist gas.

[0024] Reference Figure 1 and Figure 2 The water spray assembly includes a water pump 13, the output end of the water pump 13 is fixedly connected to a water pipe 14, the interior of the water pipe 14 is provided with a water outlet 15, and a plurality of water outlet holes 15 are provided;

[0025] Specifically, when the temperature is too high, the water pump 13 is activated to pump water through the plurality of water outlets 15 and spray it into the interior of the purification box 5, thereby achieving the effect of lowering the internal temperature.

[0026] Reference Figure 1-Figure 3 The upper surface of the centrifugal fan 2 is fixedly connected to an air outlet pipe 25, and an air outlet 26 is opened inside the air outlet pipe 25; the lower surface of the purification box 5 is fixedly connected to the support leg 19, and the outer wall of the purification box 5 is fixedly connected to the hinge 20; the outer wall of the hinge 20 is fixedly connected to the inspection door 21, and the inside of the inspection door 21 is rotatably connected to the handle 22; the inside of the handle 22 is fixedly connected to the rotating block 23, and the outer wall of the rotating block 23 is rotatably connected to the inside of the inspection door 21; the outer wall of the rotating block 23 is slidably connected to a spring 24, one end of the spring 24 is fixedly connected to the inner wall of the inspection door 21, and oil outlet pipes 17 are provided on both sides of the interior of the purification box 5, and the lower surface of the purification box 5 is fixedly connected to an oil collecting pan 18; the other end of the spring 24 is fixedly connected to the outer wall of the handle 22, and the outer wall of the rotating block 23 is fixedly connected to the outer wall of the purification box 5.

[0027] Specifically, pressing the handle 22 inward compresses the spring 24 inward, and the rotating block 23 also moves at the same time. When the handle 22 is rotated, the block 16 is driven to rotate, and the handle 22 is pulled outward, driving the inspection door 21 to open through the hinge 20, thereby facilitating inspection.

[0028] Working principle: When the equipment is needed, start the centrifugal fan 2 above the pad 1, and draw the oil into the interior of the bellows 11 through the air inlet 12. When the oil runs toward the centrifugal fan 2, it will pass through the first-level static purification module 7 and the dynamic purification module 8, and the oil mist medium in the exhaust gas will be thrown out radially from the center, and the oil guide groove is set inside the equipment, and it will be discharged to the bottom through the oil outlet pipe 17 to the interior of the oil collecting pan 18. At this time, most of the oil has been decomposed. When passing through the second-level static purification module 4, the centrifugal force generated by the rotation of the centrifugal fan 2 is used. At this time, the inertial force direction of the particulate matter is changed through the fibers of the filter, or the jet flow is forced to change direction multiple times so that the particulate matter can be adhered to the deflector 6, thereby achieving the effect of filtering the particulate matter and improving the treatment effect of the oil mist gas. When the internal pressure is too high, the drain is pulled outward. The bursting piece 10 releases the high-pressure gas inside through the bursting pool 9 to reduce the pressure. When the temperature is too high, the water pump 13 will be started, and the water pump 13 will pump water into the water pipe 14 and then spray it into the interior of the purification box 5 through multiple water outlet holes 15 to reduce the internal temperature. Finally, the purified gas inside will be transported to the outlet pipe 25 through the connecting pipe 3 and then discharged through the air outlet 26. The support legs 19 under the purification box 5 will play a weighing role. When use is finished, the handle 22 is pressed inward. At this time, the spring 24 is compressed inward, and the rotating block 23 will also move at the same time. When the handle 22 is rotated, the card block 16 is driven to rotate, and the handle 22 is pulled outward, driving the inspection door 21 to open through the hinge 20, which is convenient for maintenance. The device can not only improve the treatment effect of oil mist gas, but also achieve the effect of facilitating maintenance.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
