[0021] Each electrical device is powered by an external power supply, and the entire device is controlled by a control terminal.

[0022] The circulation component includes two rotating shafts 11, four pulleys 12 and two transmission belts 13. The two rotating shafts 11 are arranged up and down and are both placed horizontally. The end close to the net cylinder 2 is rotatably sleeved in the net cylinder 2, and the end away from the net cylinder 2 is rotatably connected to the inner side of the blade 3 through a bracket 14.

The multiple gears 17 are respectively fixedly installed on the end of the rotating shaft 11 on the bottom side of each group of circulation components, and are all meshed with the ring gear 15.

[0024] A refrigeration pump liquid device 18 is fixedly installed on the inner wall of the cover tube 7, and two liquid storage chambers 19 are provided at the top of the mesh tube 2.

[0025] A flow guide hole 22 is formed inside the blade 3 . The flow guide hole 22 is zigzag, and two ends of the flow guide hole 22 are connected to the two liquid storage chambers 19 respectively.

[0026] A plurality of air holes 23 are formed on the top of the cover tube 7. The air holes 23 are evenly distributed in a ring shape, and filter cotton 24 is fixedly installed inside.

[0027] A scraper rod 26 is fixedly installed on the outside of the net cylinder 2 through a plurality of connecting frames 25. The scraper rod 26 is spiral and in sliding contact with the inner wall of the outer shell 1. An annular groove 27 is provided on the inner side of the top of the outer shell 1. A scraper block 28 is fixedly installed on the top of the scraper rod 26. The scraper block 28 is slidably embedded in the annular groove 27. A discharge pipe 29 is fixedly installed on the outside of the top of the outer shell 1. The top of the discharge pipe 29 is connected to the annular groove 27, and the bottom end is connected to an external oil recovery device.

[0028] When the device is used, the bottom end of the housing 1 is fixedly and sealedly connected to the oil mist discharge end of the application equipment.

[0029] During the operation of the equipment, the motor 9 rotates, driving the mesh cylinder 2 to rotate, and the mesh cylinder 2 drives the multiple blades 3 located inside it to rotate. The oil mist enters through the inlet at the bottom of the outer shell 1, contacts and collides with the rotating blades 3, and the oil mist is cooled and liquefied to form oil droplets, which are attached to the blades 3. Under the action of centrifugal force, the oil droplets are separated from the blades 3, thrown out through the mesh holes of the mesh cylinder 2, and then intercepted by the inner wall of the outer shell 1 to form oil accumulation.

[0030] When the net drum 2 rotates, the pushing mechanism is driven to rotate together with the blade 3. The gear 17 rotates under the interference of the gear ring 15, driving the rotating shaft 11 on the bottom side to rotate. The rotating shaft 11 drives the pulley 12 located thereon to rotate. The pulley 12 drives the transmission belt 13 to rotate. The transmission belt 13 drives the multiple scrapers 5 located thereon to rotate. The scrapers 5 contact with the blade 3, scrape off the oil formed by liquefaction on the surface of the blade 3, and clean it with the centrifugal effect, so that it is easier to separate from the surface of the blade 3, avoid forming an oil film, ensure that the surface of the blade 3 is in a clean state, and facilitate the full liquefaction of the oil mist, thereby ensuring the efficiency of oil separation.

[0031] During the rotation of the net cylinder 2, the refrigeration pump liquid device 18 operates to continuously pump out the refrigerated liquid medium from the output end. The cooling medium flows into the guide hole 22 through the liquid storage chamber 19 connected to the output end. When passing through the blade 3 through a tortuous path, the blade 3 can be cooled and cooled, so that the blade 3 is in a low temperature state, thereby ensuring the liquefaction effect. After the cooling medium flows out from the other end of the guide hole 22, it flows back to the refrigeration pump liquid device 18 through another liquid storage chamber 19, and after being cooled again, it flows into the next cycle.

[0032] After the accumulated oil is thrown to the inner wall of the outer shell 1, the rotation of the net cylinder 2 drives the scraper rod 26 to rotate. Under the action of the spiral, the accumulated oil is transported upward and finally gathered in the annular groove 27. The scraper rod 26 drives the scraper block 28 to rotate, pushing the separated accumulated oil to the input port of the discharge pipe 29, and finally discharged through the discharge pipe 29.

[0033] The spiral push of the scraper rod 26 allows the liquefied oil to be discharged from the upper side of the equipment, avoiding contact between the oil and the untreated oil mist entering the bottom side, reducing the contamination of the accumulated oil after separation, and ensuring the effective flow of the oil mist inlet, further improving the efficiency of oil mist separation.

[0034] The separated smoke is discharged from the air hole 23 at the top of the cover tube 7 and is processed by the filter cotton 24 to ensure the cleanliness of the discharged gas and reduce pollution.

[0035] A plurality of concentration sensors 30 are fixedly mounted on the inner wall of the bottom port of the housing 1. The motor 9 is a variable frequency speed regulating model. When the oil mist passes through the bottom entrance of the housing 1, the concentration sensor 30 detects the concentration of the oil mist and promptly feeds back to the external control terminal. The control terminal adjusts the rotation speed of the motor 9 to adapt to oil mists of different concentrations, thereby further ensuring the high efficiency and adequacy of the separation.
