A limiting slot 4 is provided in the middle of the centrifugal separator 13. The outer parts of the positioning posts 5 are inserted into the limiting slot 4, and the outer parts of the limiting plates 6 are respectively nested inside the positioning grooves 22. Figure 6 The bottom end of the rotating sleeve 10 is fixedly connected to a stabilizing connecting ring 21, and the outside of the stabilizing connecting ring 21 is rotatably connected to the top of the support platform 9. Both sides of the bottom end of the waste oil filter tank 1 are fixedly connected to discharge oil cylinders 17, and the outside of the support platform 9 is fixedly connected to an activated carbon filter plate 11 for further treatment of waste oil.

[0028] The waste oil to be treated is injected into the waste oil filter tank 1 through the feeding cylinder 3, and then flows into the centrifugal separator 13. During this process, the drive motor 7 is started, driving the rotating shaft 8 to rotate, which in turn causes the rotating sleeve 10 to rotate. The limiting plate 6 inside the rotating sleeve 10 interacts with the positioning column 5, pushing the centrifugal separator 13 to rotate. Under the high-speed rotation of the centrifugal separator 13, the waste oil is subjected to centrifugal force and is thrown to the outside through the solid-liquid separation filter plate 12, re-entering the waste oil filter tank 1. Subsequently, the waste oil flows through the activated carbon filter plate 11 for further purification. This process significantly improves the solid-liquid separation efficiency of the device and accelerates the overall processing speed.

[0029] Reference Figure 2 , Figure 3 and Figure 4 A fixing ring 19 is used for the top of the inner side of the centrifugal separator 13. Multiple support columns 20 are evenly fixedly connected around the top of the fixing ring 19. Multiple hydraulic rods 15 are evenly fixedly connected to the bottom of the flip cover plate 2. A limiting ring is installed at the output end of the hydraulic rod 15 to stabilize the centrifugal separator 13.

The outer sides of the support columns 20 are respectively inserted into the slots inside the rotating ring 18. A traction oil cylinder 16 is fixedly connected to the bottom of the feeding oil cylinder 3. The outer side of the traction oil cylinder 16 is smaller than the inner side of the rotating ring 18.

[0030] After the waste oil treatment is completed, multiple starting devices 15 are activated, causing the lifting mechanism 14 to rise upwards, thereby releasing the fixed slot 18 from the periphery of the support frame 20. Next, the screw 2 at the front end is rotated to release its lock on the fixed device 2. Then, the fixed device 2 is unfolded outwards, and with the coordinated action of the multiple support frames 20, the centrifugal separator 13 is smoothly pulled upwards, achieving convenient disassembly of the centrifugal separator 13. This allows for easy cleaning of accumulated solid particles inside the separator, greatly improving the convenience of disassembly and facilitating subsequent cleaning and maintenance of the filter cartridge.

[0031] Working principle: the waste oil to be processed is added into the inside of the waste oil filter tank 1 through the feeding oil cylinder 3 and flows into the inside of the centrifugal separation cylinder 13, at this time, the driving motor 7 is started to rotate the rotating shaft 8, thereby rotating the rotating sleeve 10, the multiple limiting plates 6 on the inside of the rotating sleeve 10 contact the bottom of the centrifugal separation cylinder 13 with the positioning column 5, thereby rotating the centrifugal separation cylinder 13, with the rotation of the centrifugal separation cylinder 13, the waste oil in the inside of the centrifugal separation cylinder 13 is thrown out to the outside through the solid-liquid separation filter plate 12 due to the centrifugal force generated by the rotation of the centrifugal separation cylinder 13, and then enters the inside of the waste oil filter tank 1 again and passes through the activated carbon filter plate 11 to further process the waste oil, after the processing of the waste oil is completed, the multiple hydraulic rods 15 are started to make the pressing ring 14 lift upwards, thereby making the notch of the rotating ring 18 disengage from the outside of the supporting column 20, the screw rod at the front of the flap plate 2 is rotated to lose the fixation of the flap plate 2, the flap plate 2 is unfolded to the outside, thereby pulling out the centrifugal separation cylinder 13 upwards through the multiple supporting columns 20, thereby completing the disassembly of the centrifugal separation cylinder 13, and the solid particles in the inside are cleaned.
