[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0025] Please see Figure 1 - Figure 6 A waste emulsion recycling device based on digital twin membrane filtration includes an emulsion recycling tank 1. A first electric push rod 3 is fixedly connected to the inner wall of the emulsion recycling tank 1. A clamping horizontal plate 4 is fixedly connected to one end of the first electric push rod 3. A multi-stage filter screen 5 is movably connected to the side wall of the clamping horizontal plate 4. The side wall of the multi-stage filter screen 5 is movably connected to the inner wall of the emulsion recycling tank 1. A sealing strip 6 is fixedly connected to the top of the multi-stage filter screen 5. A third electric slide rail 18 is fixedly connected to the inner wall of the emulsion recycling tank 1. A sliding horizontal plate 19 is electrically connected to the third electric slide rail 18. A second electric push rod 20 is fixedly connected to the bottom of the sliding horizontal plate 19. A waste oil scraping box 2 is fixedly connected to the bottom of the second electric push rod 20. 1. A fixed horizontal plate 26 is fixedly connected to the inner wall of the emulsion recovery tank 1. A drain pipe 27 is connected to the bottom of the fixed horizontal plate 26. A solenoid valve 28 is installed on the drain pipe 27. A membrane filter plate 29 is fixedly connected inside the emulsion recovery tank 1. A connecting oil tank 30 is connected to the side wall of the emulsion recovery tank 1. A first oil pipe 31 is connected to the bottom of the connecting oil tank 30. A waste oil purification machine 32 is connected to the bottom of the first oil pipe 31. A second oil pipe 33 is connected to the bottom of the waste oil purification machine 32. The side wall of the emulsion recovery tank 1 is fixedly connected to the side wall of the waste oil purification machine 32. The side wall of the emulsion recovery tank 1 is fixedly connected to the side wall of the oil storage tank 34. A water level detection sensor 24 is fixedly connected to the bottom of the waste oil scraping box 21.

[0026] It should be noted that when the waste emulsion enters the emulsion recovery tank 1, it undergoes preliminary filtration using a multi-stage filter screen 5, filtering out impurities and debris and separating them to the top of the filter screen 5. The waste emulsion then flows into the top of the fixed horizontal plate 26 under gravity for sedimentation. As the sedimentation time increases, the waste oil in the waste emulsion gradually floats to the surface. At this point, the water level sensor 24 monitors the water level of the waste emulsion in real time, and simultaneously controls the second electric push rod. 20 is activated. The second electric push rod 20 drives the waste oil scraping box 21 down to the surface of the waste emulsion and below the surface of the waste oil. Then, the third electric slide rail 18 is activated. The third electric slide rail 18, through the sliding plate 19 and the second electric push rod 20, moves the waste oil scraping box 21, scraping off all the waste oil from the surface of the waste emulsion. The third electric slide rail 18 moves the waste oil in the waste oil scraping box 21 and transports it into the connecting oil tank 30. The waste oil in the connecting oil tank 30 is subjected to gravity and flows through the first oil... The waste oil flows into the waste oil purification machine 32 through pipe 31. The waste oil purification machine 32 is then started. Through a multi-stage process of membrane filtration, distillation, centrifugation, adsorption, neutralization, and filtration, the waste oil is specifically removed from its pollutants and its basic properties restored. The oil is then stored in the oil storage tank 34 through the second oil pipe 33 for subsequent lubrication of the equipment, thus reducing equipment resource consumption. After the waste emulsion has settled, the solenoid valve 28 is opened, and the waste emulsion flows into the membrane filter plate 29 under gravity from the drain pipe 27. The membrane filter plate 29 purifies and recovers the waste emulsion and inputs the purified emulsion into the bottom of the emulsion recovery tank 1. Over time, the multi-stage filter screen 5 will gradually wear down. At this time, the operator can control the first electric push rod 3 to start through the controller. The first electric push rod 3 is driven by the clamping horizontal plate 4, causing the clamping horizontal plate 4 to retract and stop clamping and limiting the multi-stage filter screen 5. This makes it easier for the operator to replace the multi-stage filter screen 5, reduces equipment downtime, and improves equipment efficiency.

[0027] In an optional embodiment: multiple crushing rollers 2 are fixedly connected to the inner wall of the emulsion recovery tank 1, and the multiple crushing rollers 2 are arranged at equal intervals.

[0028] It should be noted that when there is waste emulsion that needs to be recycled, the crushing roller 2 is activated. The crushing roller 2 crushes large impurities in the waste emulsion to prevent large impurities from clogging the multi-stage filter screen 5 in subsequent processes.

[0029] In an optional embodiment: a second electric slide rail 13 is fixedly connected to the side wall of the emulsion recovery tank 1, and the second electric slide rail 13 is electrically connected to a sliding sealing plate 14, with one side of the sliding sealing plate 14 slidably connected to the side wall of the emulsion recovery tank 1.

[0030] It should be noted that when the multi-stage filter 5 needs to be replaced, the second electric slide rail 13 is activated. The second electric slide rail 13 drives the sliding sealing plate 14 to open the interior of the emulsion recovery tank 1, making it more convenient for staff to replace the multi-stage filter 5.

[0031] In an optional embodiment: a pressing air pump 15 is fixedly connected to the side wall of the sliding sealing plate 14, and a telescopic airbag 16 is connected to one side of the pressing air pump 15. The side wall of the telescopic airbag 16 is fixedly connected to the inner wall of the sliding sealing plate 14.

[0032] It should be noted that when the sliding sealing plate 14 seals the inside of the emulsion recovery tank 1, the operator can press the air pump 15. Pressing the air pump 15 will introduce air into the telescopic airbag 16, causing it to expand and seal the inside of the emulsion recovery tank 1, preventing waste emulsion from seeping out from the gap between the emulsion recovery tank 1 and the sliding sealing plate 14.

[0033] In an optional embodiment: a first electric slide rail 7 is fixedly connected to the inner wall of the emulsion recovery tank 1, and a sliding push plate 8 is electrically connected to the first electric slide rail 7. The bottom of the sliding push plate 8 is slidably connected to the top of the multi-stage filter screen 5.

[0034] It should be noted that as the working time of the multi-stage filter screen 5 increases, the amount of impurities on the top of the multi-stage filter screen 5 gradually increases. At this time, the operator can activate the first electric slide rail 7 through the controller. The first electric slide rail 7 drives the sliding push plate 8 to scrape all the solid impurities on the surface of the multi-stage filter screen 5 out of the emulsion recovery tank 1, so as to prevent the excessive impurities on the top of the multi-stage filter screen 5 from affecting its separation efficiency.

[0035] In an optional embodiment: the side wall of the emulsion recovery tank 1 is connected to a waste storage tank 10, an electromagnet 11 is fixedly connected inside the waste storage tank 10, and a water filter screen 12 is fixedly connected to the inner wall of the waste storage tank 10.

[0036] It should be noted that the waste storage box 10 can be used to store solid impurities scraped out by the sliding push plate 8. The electromagnet 11 can absorb and screen metal fragments in the solid impurities, making it more convenient for staff to recycle the metal fragments later. The water filter 12 can filter water from the solid impurities.

[0037] In an optional embodiment: a third electric push rod 22 is fixedly connected to the inner wall of the waste oil scraping box 21, and an oil pushing vertical plate 23 is fixedly connected to one end of the third electric push rod 22. The side wall of the oil pushing vertical plate 23 is slidably connected to the inner wall of the waste oil scraping box 21.

[0038] It should be noted that after the waste oil scraping box 21 moves the waste oil into the connecting oil tank 30, the third electric push rod 22 is activated. The third electric push rod 22 drives the oil pushing vertical plate 23 to extend, pushing all the waste oil in the waste oil scraping box 21 into the connecting oil tank 30, preventing waste oil from remaining in the waste oil scraping box 21.

[0039] In an optional embodiment: a transparent vertical plate 17 is fixedly connected to the inner wall of the oil storage tank 34. The transparent vertical plate 17 is made of tempered glass. A first inclined plate 9 is fixedly connected to the inside of the emulsion recovery tank 1. A second inclined plate 25 is fixedly connected to the inner wall of the waste oil scraping tank 21.

[0040] It should be noted that, with the help of the transparent vertical plate 17 made of tempered glass, the staff can directly observe the storage effect and storage amount of lubricating oil inside the oil storage tank 34 through the transparent vertical plate 17. At the same time, the setting of the first inclined plate 9 and the second inclined plate 25 can prevent waste liquid from flowing out of the emulsion recovery tank 1 and the waste oil scraping tank 21 without the action of external force.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] During operation, when there is waste emulsion that needs to be recycled, the crushing roller 2 is activated. The crushing roller 2 crushes large impurities in the waste emulsion to prevent large impurities from clogging the multi-stage filter screen 5 in subsequent processes.

[0043] When the waste emulsion enters the emulsion recovery tank 1, it undergoes preliminary filtration using a multi-stage filter screen 5, removing impurities and debris and separating them to the top of the filter screen 5. The waste emulsion then flows under gravity to the top of the fixed horizontal plate 26 for sedimentation. As sedimentation time increases, the waste oil in the waste emulsion gradually floats to the surface. At this point, the water level sensor 24 monitors the water level in real time and simultaneously controls the second electric push rod 20 to start. The second electric push rod 20 drives the waste oil scraping box 21 down to the surface of the waste emulsion, and then down below the surface of the waste oil. Next, the third electric slide rail 18 is activated. The third electric slide rail 18, through the sliding plate 19 and the second electric push rod 20, moves the waste oil scraping box 21, scraping away all the waste oil from the surface of the waste emulsion. The third electric slide rail 18 then moves the waste oil in the waste oil scraping box 21 and transports it into the connecting oil tank 30. Inside the connecting oil tank 30, the waste oil, under the influence of gravity, flows through the first oil pipe 31. The waste oil is fed into the waste oil purification machine 32 and started. The waste oil purification machine 32 uses a multi-stage process of membrane filtration, distillation, centrifugation, adsorption, neutralization and filtration to specifically remove pollutants from the waste oil and restore its basic properties. The oil is then fed into the storage tank 34 through the second oil pipe 33 for subsequent lubrication of the equipment, thereby reducing the loss of equipment resources. After the waste emulsion has settled, the solenoid valve 28 is opened. The waste emulsion flows into the membrane filter plate 29 from the drain pipe 27 under the action of gravity. The membrane filter plate 29 purifies and recovers the waste emulsion and feeds the purified and recovered emulsion into the bottom of the emulsion recovery tank 1. Over time, the multi-stage filter screen 5 will gradually wear down. At this time, the operator can control the first electric push rod 3 to start through the controller. The first electric push rod 3 drives the clamping horizontal plate 4 to retract and stop clamping and limiting the multi-stage filter screen 5, making it easier for the operator to replace the multi-stage filter screen 5, reducing equipment downtime and improving equipment efficiency.

[0044] When the multi-stage filter 5 needs to be replaced, the second electric slide rail 13 is activated. The second electric slide rail 13 drives the sliding sealing plate 14 to open the interior of the emulsion recovery tank 1, making it more convenient for staff to replace the multi-stage filter 5.

[0045] When the sliding sealing plate 14 seals the inside of the emulsion recovery tank 1, the operator can press the air pump 15. Pressing the air pump 15 will introduce air into the telescopic airbag 16, causing it to expand and seal the inside of the emulsion recovery tank 1, preventing waste emulsion from seeping out from the gap between the emulsion recovery tank 1 and the sliding sealing plate 14.

[0046] As the working time of the multi-stage filter screen 5 increases, the impurities on the top of the multi-stage filter screen 5 gradually increase. At this time, the staff can start the first electric slide rail 7 through the controller. The first electric slide rail 7 drives the sliding push plate 8 to scrape all the solid impurities on the surface of the multi-stage filter screen 5 out of the emulsion recovery tank 1, so as to prevent the excessive impurities on the top of the multi-stage filter screen 5 from affecting its separation efficiency.

[0047] The waste storage box 10 can be used to store solid impurities scraped out by the sliding push plate 8. The electromagnet 11 can absorb and screen metal fragments in the solid impurities, making it more convenient for staff to recycle metal fragments later. The filter screen 12 can filter water from the solid impurities.

[0048] When the waste oil scraping box 21 moves the waste oil into the connecting oil tank 30, the third electric push rod 22 is activated. The third electric push rod 22 drives the oil pushing vertical plate 23 to extend, pushing all the waste oil in the waste oil scraping box 21 into the connecting oil tank 30, preventing waste oil from remaining in the waste oil scraping box 21.

[0049] With the help of the transparent vertical plate 17 made of tempered glass, the staff can directly observe the storage effect and storage volume of lubricating oil inside the oil storage tank 34. At the same time, the setting of the first inclined plate 9 and the second inclined plate 25 can prevent waste liquid from flowing out of the emulsion recovery tank 1 and the waste oil scraping tank 21 without external force.
