A separation plate 24 is arranged on the right side of the partition plate 1. The separation plate 24 is fixedly connected with a partition plate 2 30 on the right side. A drain hole 31 is opened at the front side of the bottom of the right side of the separation tank 1. An oil discharge hole 32 is opened on the side of the bottom of the right side of the separation tank 1 away from the drain hole 31.

[0033] Specifically, the solution delivery pipe 4 is used to transport the liquid to be separated from oil and water into the separation tank 1. The filter tank 5 is used to intercept the impurities in the liquid flowing into the separation tank 1, so as to remove the impurities in most of the liquid. The discharge chute 7 is used to pour the impurities in the filter tank 5. The three fixing brackets 37 are used to fix the position of the heating pipe 38 at the bottom of the discharge chute 7, and the heating pipe 38 is used to preliminarily heat the filtered liquid.

The water level sensor 23 is used to detect the position of the liquid in the separation tank 1, so as to send a signal to the electric push rod 20 to operate. The electric push rod 20 is used to drive the scraping plate 22 and the water level sensor 23 to move up and down, so that the scraping plate 22 touches the water surface position, which is convenient for removing the floating oil. The partition plate 2 30 is used to isolate the separated oil and water in the separation tank 1, so that the floating oil is discharged from the oil discharge hole 32, and the separated liquid is discharged from the drain hole 31.

[0034] Refer to Figures 2-3 , a separation component is slidably connected inside the separation plate 24. The separation component includes an inner chute 25 which is opened on the front side inside the separation plate 24. A partition plate 26 is slidably connected inside the inner chute 25. A pull rod 27 is fixedly connected to the top of the partition plate 26. A second diversion hole 28 is opened on one side of the bottom right of the separation plate 24. The second diversion hole 28 communicates with the inner chute 25. A sunken groove 29 is opened on the rear side of the top of the separation plate 24. A through groove 33 is opened on the top front side of the separation box 1. A hair dryer 34 is fixedly installed inside the through groove 33. The hair dryer 34 is located in front of the scraping plate 22. The heating plate 19 is located between the first isolation plate 3 and the separation plate 24.

[0035] Specifically, the second diversion hole 28 is used to direct the separated liquid towards the drainage hole 31, thereby achieving the oil-water separation effect of the vanadyl sulfate solution. By opening the inner chute 25, the partition plate 26 and the sliding rod 17 can move up and down inside, and at the same time, it is used to block the second diversion hole 28. By setting the hair dryer 34, it is used to blow the separated floating oil towards the position of the scraping plate 22, thereby improving the efficiency of separating oil and water.

[0036] Refer to Figures 2-5 , a cover plate 35 is fixedly installed on the top of the U-shaped mounting frame 12. The sliding sleeve 18 is welded to the top of the lead screw nut 15. One end of the lead screw 14 away from the servo motor 13 penetrates through the U-shaped mounting frame 12 and is sleeved inside the fixed seat 16. The lead screw 14 is horizontally arranged. The sliding rod 17 is located on the top of the lead screw 14. A filter plate 36 is fixedly installed on the bottom left of the separation plate 24. The mesh number of the filter plate 36 is greater than that of the filter box 5. The filter plate 36 is located on the left side of the three diversion holes. Support legs 2 are welded to the four corners of the bottom of the separation box 1. Handles 6 are fixedly installed on both sides of the top front of the filter box 5. Rotating shafts 8 are fixedly connected to both sides of the discharge chute 7. A U-shaped groove 9 is opened on one side of the top of the separation box 1. Insertion holes 10 are opened on both sides of the inner wall of the U-shaped groove 9.

[0037] Specifically, by fixedly installing the cover plate 35 on the top of the U-shaped mounting frame 12, it is used to prevent personnel from accidentally touching the rotating lead screw 14 and improve the safety of device use. By horizontally arranging the lead screw 14, it is used to drive the lead screw nut 15 and the scraping plate 22 to move horizontally, facilitating the removal of the separated floating oil. The filter plate 36 is used to filter fine impurities in the vanadyl sulfate solution and improve the quality of the recovered vanadyl sulfate solution. By setting the rotating shafts 8 and the handles 6, it is convenient for the user to pour the filter box 5 filled with impurities.

[0038] Working principle: When in use, the vanadyl sulfate solution to be separated from oil and water is discharged through the solution delivery pipe 4. After being discharged, the solution first falls into the interior of the filtration tank 5, and the impurities mixed in the solution flowing into the filtration tank 5 are intercepted. Subsequently, the filtered liquid flows into the bottom of the separation tank 1, and the solution continues to flow to the right from the three groups of first diversion holes 11. When the liquid level inside the separation tank 1 continues to rise, the heating tube 38 is started to heat the solution flowing down from the filtration tank 5. Then, the heating plate 19 is turned on to heat the solution flowing out from the three groups of first diversion holes 11 again. After being heated twice, the solution in the separation tank 1 quickly undergoes an oil-water separation reaction, with the oil floating on top of the water. As the vanadyl sulfate solution is continuously injected into the separation tank 1, the liquid level of the solution keeps rising. When the water level sensor 23 detects and touches the liquid level, the water level sensor 23 sends a signal for the servo motor 13 and the hair dryer 34 to run synchronously. The hair dryer 34 blows the separated floating oil to one side of the scraper 22. After the servo motor 13 runs, it synchronously drives the lead screw 14 to rotate. When the lead screw 14 rotates, it synchronously drives the lead screw nut 15 to move horizontally. The sliding sleeve 18 moves horizontally on the surface of the sliding rod 17. The lead screw nut 15 synchronously drives the electric push rod 20, the cross plate 21, and the scraper 22 to move horizontally. When the scraper 22 moves, it can push the floating oil floating upward to the right. The floating oil is pushed to the sunken groove 29 and then flows to the rear side of the rear isolation plate two 30, and then is discharged along the oil discharge hole 32. When the scraper 22 moves to the rightmost side, the output end of the electric push rod 20 moves upward, synchronously driving the scraper 22 to move upward. When the water level sensor 23 is separated from the liquid, the servo motor 13 rotates in reverse, driving the lead screw nut 15, the electric push rod 20, and the scraper 22 to move to the left. After the scraper 22 moves to the leftmost side, the electric push rod 20 operates to push the cross plate 21, the scraper 22, and the water level sensor 23 to move downward. When the floating oil is completely discharged, the pull rod 27 is pulled upward to drive the partition plate 26 to move upward inside the inner chute 25. At this time, the second diversion hole 28 is opened, and the separated liquid flows in the direction of the drain hole 31 from the diversion hole, and finally the separated liquid is discharged from the drain hole 31, and the floating oil is discharged from the oil discharge hole 32.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
