[0016] Technical effects and advantages of this utility model:
[0017] 1. By setting an oil film cleaning component, the first scraper performs a circular motion to scrape the oil film around the inner wall, and the second scraper performs a circular motion to scrape the oil film on the outer wall of the oil outlet pipe. The first scraper drives the oil film pipeline to perform a circular motion above the oil outlet pipe. At this time, the oil film on the inner wall of the shell scraped by the first scraper will move upward along the guidance of the first scraper. At this time, the upward oil film will be guided into the oil film channel, enter the oil outlet pipe from the oil film channel, and finally flow out through the oil outlet. The rotating shaft drives the third connecting rod to perform a circular motion, and the third connecting rod drives the third scraper to perform a circular motion. Through the circular motion, the third scraper scrapes the oil film on the inner wall of the oil outlet pipe. At the same time, the third scraper extends very long to prevent the oil outlet pipe from being blocked. Compared with the existing technology, this technology can scrape the accumulated oil film on the inner wall of the shell, the inner wall and outer wall of the oil outlet pipe, so that these oil films are discharged through the oil outlet, so that these oil stains will not accumulate in the shell.
[0018] 2. By setting up an acoustic self-cleaning component, the acoustic wave transmitter emits ultrasonic waves, which pass through the resonant shell and enhance the sound waves. The emitted ultrasonic waves hit the multiple diffraction holes on the diffraction disk, and derive multiple acoustic wave sources to impact the oil-water mixture emulsion in the shell, breaking it. Finally, it is filtered through the oil-water filter and discharged through the oil outlet pipe. When the oil-water separation work is completed, all valves are closed, and clean water is injected into the shell through the water inlet pipe. When the water level reaches the oil outlet pipe through the observation window, the acoustic wave transmitter continues to emit ultrasonic waves to impact the clean water injected into the shell. The vibration generated by the clean water after impacting the clean water and the action of the ultrasonic wave itself shake the oil stains on the components into the water, and then the liquid is discharged and collected through the sewage pipe. Compared with the existing technology, this technology can break up the emulsion in the oil-water mixture by enhancing ultrasonic waves and deriving new wave sources, and can realize the function of degreasing various components in the shell.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] As attached Figure 1-8 The oil-water separator shown is easy to clean, comprising a housing 1, a water inlet pipe 2 provided on one side of the housing 1, a filter screen 3 provided at one end of the water inlet pipe 2, an observation window 4 provided at the top of the water inlet pipe 2, a top cavity 5 provided at the top of the housing 1, a horizontal plate 6 fixedly provided inside the top cavity 5, a motor 7 fixedly provided on the top of the horizontal plate 6, and an oil film cleaning assembly fixedly provided at the bottom of the motor 7;
[0030] The oil film cleaning assembly includes a rotating shaft 8, which is fixedly connected to the motor 7. A first connecting rod 9 is fixedly arranged on one side of the rotating shaft 8. A second connecting rod 10 is fixedly arranged on the bottom end of the first connecting rod 9. A first scraper 11 is fixedly arranged on one end of the second connecting rod 10. The shape of the first scraper 11 is set to be a micro-spiral. A second scraper 12 is fixedly arranged on the other end of the second connecting rod 10. A third connecting rod 13 is fixedly arranged on one side of the rotating shaft 8. A third scraper 14 is fixedly arranged on one end of the third connecting rod 13. The third scraper 14 and the second scraper 12 are set to be triangular prisms. An oil film channel 15 is fixedly arranged on one side of the first scraper 11. A fourth connecting rod 16 is fixedly arranged on the top of the oil film channel 15. One end of the fourth connecting rod 16 is fixedly connected to the rotating shaft 8. An acoustic wave self-cleaning assembly is fixedly arranged on the bottom of the horizontal plate 6.
[0031] In some embodiments, according to Figure 1 As shown, the acoustic self-cleaning component includes a resonant shell 17, which is fixedly connected to the horizontal plate 6. Two acoustic wave emitters 18 are fixedly provided inside the resonant shell 17. A diffraction disk 19 is provided at the bottom of the two acoustic wave emitters 18. A plurality of diffraction holes 20 are opened on the surface of the diffraction disk 19, and the diffraction disk 19 is fixedly connected to the rotating shaft 8.
[0032] In some embodiments, according to Figure 1 As shown, a water outlet pipe 21 is provided on the other side of the shell 1, and an annular pipe 22 is fixedly provided at one end of the water outlet pipe 21. Four L-shaped pipes 23 are provided on the outer wall of the annular pipe 22. An oil-water filter 24 is provided on the top of each of the four L-shaped pipes 23. When the oil-water mixture contacts the oil-water filter 24, the oil-water filter 24 will isolate the oil from the outside. By continuously injecting the oil-water mixture, the oil will gradually mix. Since the density of the oil is less than that of water, the oil will gradually gather in the upper layer. When the oil is higher than the inlet of the oil outlet pipe 26, the oil will pass through the oil outlet pipe 26 to the oil outlet 25 and flow out from the oil outlet 25. The water that passes through the oil-water filter 24 will enter the annular pipe 22 through the L-shaped pipe 23 and finally flow out from the water outlet pipe 21.
[0033] In some embodiments, according to Figure 1 As shown, an oil outlet 25 is fixedly provided at the bottom of the shell 1, an oil outlet pipe 26 is fixedly provided at the top of the oil outlet 25, an annular groove 27 is provided at the top of the oil outlet pipe 26, a slider 28 is slidingly provided inside the annular groove 27, and the top of the slider 28 is fixedly connected to the oil film channel 15.
[0034] In some embodiments, according to Figure 1As shown, a sewage pipe 29 is provided on one side of the oil outlet 25 , and the sewage pipe 29 is fixedly connected to the housing 1 . Valves 30 are fixedly provided inside the sewage pipe 29 , the oil outlet 25 and the water outlet pipe 21 .
[0035] In some embodiments, according to Figure 1 As shown, two support plates 31 are fixedly provided on the outer wall of the housing 1 , and a plurality of support legs 32 are fixedly provided between the two support plates 31 .
[0036] Working principle of this utility model:
[0037] When in use, the staff turns on the motor 7, closes all valves 30, and injects the oil-water mixture into the housing 1 through the water inlet pipe 2. The water inlet pipe 2 is equipped with a filter 3 to filter food residues in the oil-water mixture. The water level in the housing 1 is observed through the observation window 4. When the water level reaches one centimeter below the oil outlet 25, all valves 30 are opened, and the utility model starts to separate oil and water.
[0038] When the oil-water mixture contacts the oil-water filter 24, the oil-water filter 24 isolates the oil from the outside. By continuously injecting the oil-water mixture, the oil will gradually mix. Since the density of oil is less than that of water, the oil will gradually accumulate in the upper layer. When the oil is higher than the inlet of the oil outlet pipe 26, the oil will pass through the oil outlet pipe 26 to the oil outlet 25 and flow out from the oil outlet 25. The water that has passed through the oil-water filter 24 will enter the annular pipe 22 through the L-shaped pipe 23 and finally flow out from the water outlet pipe 21.
[0039] After working for a long time, a large amount of oil film will be attached to the inner wall of the shell 1 and the inside and outside of the oil outlet pipe 26. At this time, the motor 7 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the first connecting rod 9 to make a circular motion. The first connecting rod 9 drives the second connecting rod 10 to make a circular motion, and the second connecting rod 10 drives the first scraper 11 and the second scraper 12 to make a circular motion. In this way, the first scraper 11 scrapes off the oil film on the inner wall through a circular motion, and the second scraper 12 scrapes off the oil film on the outer wall of the oil outlet pipe 26 through a circular motion. The oil film pipeline is driven by the first scraper 11, so that the oil film pipeline is smooth. The oil film scraped off by the first scraper 11 on the inner wall of the housing 1 will move upward along the guidance of the first scraper 11. The upward oil film will be guided into the oil film channel 15, enter the oil outlet pipe 26 from the oil film channel 15, and finally flow out through the oil outlet 25. The rotating shaft 8 drives the third connecting rod 13 to make a circular motion, and the third connecting rod 13 drives the third scraper 14 to make a circular motion. Through the circular motion, the third scraper 14 scrapes the oil film on the inner wall of the oil outlet pipe 26. At the same time, the third scraper 14 extends very long to prevent the oil outlet pipe 26 from being blocked.
[0040] During the oil-water separation process, the injected oil-water mixture often contains an oil-water emulsion, which is difficult to be filtered by the oil-water filter 24. At this time, the sound wave transmitter 18 emits ultrasonic waves, which pass through the resonance shell 17 to amplify the sound waves. The emitted ultrasonic waves hit the multiple diffraction holes 20 on the diffraction disk 19, deriving multiple sound wave sources to impact the oil-water emulsion in the housing 1, breaking it up. Finally, it is filtered through the oil-water filter 24 and discharged through the oil outlet pipe 26.
[0041] When the oil-water separation work is completed, all valves 30 are closed, and clean water is injected into the shell 1 through the water inlet pipe 2. When the water level reaches the oil outlet pipe 26 as observed through the observation window 4, the sound wave transmitter 18 continues to emit ultrasonic waves to impact the clean water injected into the shell 1. The vibration generated by the clean water after impacting the clean water and the effect of the ultrasonic waves themselves shake the oil stains on the components into the water, and then the liquid is discharged and collected through the sewage pipe 29, and finally the motor 7 is turned off.
