In this example, the top of the cover 2 has symmetrically arranged water inlets, and the bottom of the housing 1 has a discharge outlet. A motor 5 is located on the top of the cover 2. A fixing mechanism connected to the lugs 3 is symmetrically arranged on the upper side wall of the housing 1. A retaining seat 8 is symmetrically arranged on the inner wall of the housing 1, and an oil-water separator 6 is arranged between the retaining seats 8. A retaining strip 7 is symmetrically arranged on the outer wall of the oil-water separator 6. A retaining groove adapted to the retaining strip 7 is opened on the side wall of the retaining seat 8. The separator 6 is equipped with a rotating shaft 9, which is movably connected to the output end of the motor 5. A fixing frame 10 is fitted outside the rotating shaft 9, and the two ends of the fixing frame 10 are detachably connected to the inner wall of the oil-water separator 6. The inner wall of the cover 2 is symmetrically equipped with partition frames 13. A filter screen 14 is fitted outside the rotating shaft 9 at the bottom of the partition frame 13. A symmetrical insert plate 15 is fitted at the top of the filter screen 14 and is inserted into the partition frame 13. A connecting component is provided outside the partition frame 13 on the inner side of the cover 2. The fixing mechanism includes a connecting seat 4, which is symmetrically arranged on the outside of the box body 1.

[0024] In this example, the fixing mechanism also includes a rotating shaft 18. A cavity is provided inside the connecting seat 4. The rotating shaft 18 is rotatably installed in the cavity. A gear 19 is sleeved on the outside of the rotating shaft 18. A rack 17 is meshed with one side of the gear 19. Both ends of the rack 17 pass through the upper and lower walls of the connecting seat 4. The upper end of the rack 17 is fixedly connected to the lug 3. A limiting groove is provided at one end of the rotating shaft 18. A hexagonal prism 20 and a spring 21 are provided in the limiting groove. The spring 21 is located on the side away from the opening of the limiting groove. A push rod 22 is rotatably connected to one end of the hexagonal prism 20 on the outside of the connecting seat 4. A through groove adapted to the hexagonal prism 20 is provided on the side wall of the connecting seat 4. A push handle is connected to one end of the push rod 22. A trigger assembly is provided on the outside of the box body 1. Through the fixing mechanism, the box cover 2 and the box body 1 can be connected and fixed conveniently and quickly. With the trigger assembly, disassembly can be convenient and quick. In this example, the connecting assembly includes a plug rod 26, which is symmetrically arranged on the outside of the cover 2. One end of the plug rod 26 is connected to a handle, and the other end of the plug rod 26 passes through the insertion hole on the insert plate 15. A stop block 27 and a second spring 28 are fitted on the outer wall of the plug rod 26 between the cover 2 and the partition frame 13. The stop block 27 is located on the side away from the partition frame 13. The two ends of the second spring 28 are fixedly connected to the stop block 27 and the partition frame 13, respectively. Through the connecting assembly, the filter screen 14 can be easily disassembled and installed to clean the filter material or to clean and replace the filter screen 14. In this example, the triggering assembly includes a fixing ring 23, which is fixedly fitted below the connecting seat 4 on the outside of the box body 1. A rotating ring 24 is movably fitted on the outside of the fixing ring 23. A push rod 25 is symmetrically arranged on the top of the rotating ring 24, and one end of the push rod 25 corresponds to the push handle. Through the triggering assembly, multiple push handles can be driven simultaneously, facilitating the separation between the cover 2 and the box body 1. In this example, the fixed frame 10 is rotatably connected to the rotating shaft 9 via bearings. A docking post 12, which is hexagonal, is connected to the upper end of the rotating shaft 9. The output end of the motor 5 has a docking groove adapted to the docking post 12. Scrapers 16 are symmetrically arranged on the outer side of the output end of the motor 5, with the lower end of the scraper 16 contacting the top surface of the filter screen 14. This facilitates the connection and power transmission between the rotating shaft 9 and the motor 5, and allows for easy separation. In this example, pressure blocks are symmetrically arranged on the inner wall of the cover 2 at the top of the card seat 8. Several stirring rods 11 are arranged on the outer wall of the rotating shaft 9. Several oil-water separation membranes are symmetrically arranged on the side wall of the oil-water separation cylinder 6 to limit the movement of the card strip 7 and the card seat 8, and to accelerate the separation of the oil-water mixture.

[0025] The working principle of this invention is as follows: In use, the oil-water mixture enters the tank 1 through the inlet and passes through the filter screen 14 on the tank cover 2. The filter screen 14 filters impurities from the oil and water, and the oil-water mixture flows into the oil-water separation cylinder 6. It is then filtered through the oil-water separation membrane on the oil-water separation cylinder 6. Simultaneously, the motor 5, in conjunction with the docking column 12 and the docking groove, drives the rotating shaft 9 to rotate. The rotating shaft 9 then drives the stirring rod 11 to rotate, which in turn drives the oil-water mixture to rotate. Through centrifugal force, the oil-water mixture is swung and thrown onto the oil-water separation membrane. The oil-water mixture utilizes centrifugal force to increase the contact force with the oil-water separation membrane. The membrane adsorbs the oil in the mixture and flings the water into the tank 1, thus accelerating the oil-water separation process. The water in the mixture is collected in the tank 1 and discharged through the outlet, thereby separating the oil and water. The rotation of the output shaft of the motor 5 drives the scraper 16 to rotate and clean impurities on the filter screen 14, preventing clogging and affecting the filtration effect. When it is necessary to disassemble the tank 1 and the cover 2, the oil-water separation cylinder 6 and other components inside the tank 1 can be maintained. During maintenance, rotating the rotating ring 24 on the fixed ring 23 will simultaneously move the extrusion rod 25, causing one end of the extrusion rod 25 to press and push the push handle. The push handle then drives the push rod 22 to push the hexagonal prism 20 into the limiting groove, while simultaneously compressing the spring 21. When the hexagonal prism 20 is fully inserted into the rotating shaft 18, the cover 2 can be pulled up, causing the lug 3 and rack 17 to move upwards synchronously. This causes the rack 17 to drive the gear 19, which in turn drives the rotating shaft 18 to rotate, allowing the rack 17 to be pulled out, thus separating the cover 2 from the housing 1. Then, the oil-water separator 6 can be pulled up and removed for maintenance. For maintenance, pull the handle to move the insertion rod 26, which in turn moves the stop block 27 to stretch the spring 28. This causes the insertion rod 26 to pass through one end of the insertion plate 15 and move out. Then, pull down the filter screen 14 to separate the insertion plate 15 from the partition frame 13. This allows for cleaning of filtered impurities or washing and replacing the filter screen 14. After cleaning the filter screen 14, repeat the above steps. Then, insert the insertion plate 15 into the partition frame 13 and release the pull force on the handle. The stop block 27, under the elastic force of the spring 28, will move the insertion rod 26 back to its original position, thus passing through the insertion hole on the insertion plate 15 and completing the installation of the filter screen 14.When connecting the housing 1 and the cover 2, slide the retaining strip 7 into the retaining seat 8 to install the oil-water separator 6. Rotate the rotating ring 24 to move the extrusion rod 25, causing it to press and push the push handle, which in turn pushes the push rod 22, thereby pushing the hexagonal prism 20 to compress the spring 21 until the hexagonal prism 20 enters the rotating shaft 18. Then, align the rotating shaft 9 with the output end of the motor 5, place the cover 2 on the housing 1, and pass the upper end of the rotating shaft 9 through the hole in the filter screen 14. This allows the connecting post 12 to be inserted into the connecting groove on the output end of the motor 5, and the filter screen... 14 is located inside the oil-water separator 6, while the cover 2 is placed on top of the housing 1. Simultaneously, the rack 17 is inserted into the hole on the connecting seat 4, meshing with the gear 19 and driving the gear 19 to rotate the rotating shaft 18 until the cover 2 and housing 1 are in contact. Then, the rotating ring 24 causes the extrusion rod 25 to separate from the push handle, and the hexagonal prism 20 returns to its original position under the elastic force of the spring 21, inserting into the through slot. This completes the restriction and fixation of the rotating shaft 18, thus completing the connection and fixation between the housing 1 and the cover 2. This design is convenient, quick, and highly practical.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
