[0037] Each electrical device is powered by an external power supply, and the entire device is controlled by a control terminal. Since the control terminal is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0038] 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 the bracket 14. The four pulleys 12 are respectively fixedly mounted on the two rotating shafts 11 and are symmetrically arranged. The two transmission belts 13 are respectively rollingly embedded in the two pulleys 12 on the same side, and the scrapers 5 are fixedly mounted on the two transmission belts 13.

[0039] The linkage mechanism includes a ring gear 15, multiple connecting rods 16 and multiple gears 17. The ring gear 15 is fixedly connected to the inner wall of the bottom end of the shell 1 through multiple connecting rods 16. The number of gears 17 corresponds to the number of pushing mechanisms. 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.

[0040] 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 opened at the top of the mesh tube 2. The upper sides of the two liquid storage chambers 19 are sealed and rotated with sealing rings 20. The tops of the two sealing rings 20 are vertically fixed with conduits 21. The two conduits 21 are respectively sealed and connected with the input end and output end of the refrigeration pump liquid device 18.

[0041] A guide hole 22 is formed inside the blade 3 . The guide hole 22 is zigzag, and both ends of the guide hole 22 are connected to the two liquid storage chambers 19 respectively.

[0042] The top of the cover tube 7 is provided with a plurality of air holes 23 , which are evenly distributed in a ring shape, and filter cotton 24 is fixedly installed inside.

[0043] A scraper rod 26 is fixedly installed on the outside of the net cylinder 2 through multiple 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 drainage pipe 29 is fixedly installed on the outside of the top of the outer shell 1. The top of the drainage pipe 29 is connected to the annular groove 27, and the bottom end is connected to an external oil recovery device.

[0044] When using this device, the bottom end of the housing 1 is fixedly and sealedly connected to the oil mist discharge end of the application equipment.

[0045] 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 shell 1, contacts and collides with the rotating blades 3, and the oil mist is cooled and liquefied to form oil droplets. It adheres to the blades 3 and is separated from the blades 3 under the action of centrifugal force. It is thrown out through the mesh holes of the mesh cylinder 2 and then intercepted by the inner wall of the shell 1 to form oil accumulation.

[0046] When the mesh drum 2 rotates, it drives the pushing mechanism to rotate together with the blade 3. The gear 17 rotates under the interference of the ring gear 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 the blade 3, scrape off the oil liquefied on the surface of the blade 3, and cooperate with the centrifugal effect to clean it, making it easier to separate from the surface of the blade 3, avoiding the formation of an oil film, ensuring that the surface of the blade 3 is in a clean state, and facilitating the full liquefaction of the oil mist, thereby ensuring the efficiency of oil separation.

[0047] During the rotation of the mesh drum 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, is cooled again, and flows into the next cycle.

[0048] After the accumulated oil is thrown to the inner wall of the shell 1, the rotation of the mesh drum 2 drives the scraper rod 26 to rotate. Under the action of the spiral, the accumulated oil is transported upward and finally gathers 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.

[0049] The spiral push of the scraper 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 at the same time ensuring the effective flow rate of the oil mist inlet, further improving the efficiency of oil mist separation.

[0050] 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.

[0051] A plurality of concentration sensing devices 30 are fixedly mounted on the inner wall of the bottom port of the housing 1. The motor 9 is a variable frequency speed regulation model. When the oil mist passes through the bottom inlet of the housing 1, the concentration sensing device 30 detects the concentration of the oil mist and promptly feeds back to the external control terminal. The control terminal adjusts the speed of the motor 9 to adapt to oil mists of different concentrations, thereby further ensuring efficient and sufficient separation.
