A plurality of uniformly distributed filter holes are arranged at the bottom, front side, and rear side of the filter frame 5. Both sides of the filter frame 5 are fixed with second rotating shafts. One second rotating shaft is rotatably connected to the partition plate 2, and the other second rotating shaft passes through the side wall of the housing 1 and is fixedly connected to a second rotating motor 17 on the outer wall of the housing 1. The second rotating motor 17 drives the filter frame 5 to swing back and forth to improve the filtering effect of waste oil.

[0023] The cleaning mechanism includes a top plate 6 fixed to the upper part of the housing 1, a moving plate 7 slidably connected to the bottom of the top plate 6, a rotating rod 8, a first treatment plate 9, and a second treatment plate 10. The sliding connection between the top plate 6 and the moving plate 7 can select a guide rail and a slider. By driving the slider to move on the guide rail through a driving motor, the left and right movement of the cleaning mechanism can be driven. Both sides of the bottom of the moving plate 7 are fixed with cylinders 11. The cylinders 11 are connected to the support rods 12 through telescopic rods. The up and down movement of the support rods 12 can be driven by the cylinders 11.

[0024] Both ends of the rotating rod 8 are rotatably connected to the lower part of the support rod 12, and the first processing plate 9 and the second processing plate 10 are respectively slidably connected to the top and bottom of the rotating rod 8. First rotating shafts are fixed at both ends of the rotating rod 8. One first rotating shaft is rotatably connected to the lower part of the corresponding support rod 12, and the other first rotating shaft passes through the corresponding support rod 12 and is fixedly connected to the first rotating motor 16 on the support rod 12. The first rotating motor 16 can drive the rotation of the rotating rod 8, thereby realizing the adjustment of the positions of the first processing plate 9 and the second processing plate 10.

[0025] See Figure 4 , a plurality of cleaning heads 13 are provided at both ends of the first processing plate 9 and the bottom of the second processing plate 10. A scraping blade 18 and cleaning teeth 19 are fixed to the lower part of the cleaning head 13 at the bottom of the second processing plate 10, and the height of the scraping blade 18 is lower than that of the cleaning teeth 19. The cleaning head 13 extends into the filter holes, and the impurities can be cleaned off by the cleaning teeth 19 on both sides to realize the cleaning of the filter holes.

[0026] A straight guide rail perpendicular to the front wall of the housing 1 is provided at the top of the rotating rod 8. The bottom of the first processing plate 9 is slidably connected to the straight guide rail through the first slider 14, and the first slider 14 is connected to a motor to drive the first processing plate 9 to move back and forth.

The top of the second processing plate 10 is slidably connected to the circular guide rail through the second slider 15, and the second slider 15 is connected to a motor to drive the second processing plate 10 to perform a circular motion. Through the circular motion of the second processing plate 10, the cleaning head 13 at the bottom of the second processing plate 10 can be driven to perform a circular motion in the filter holes, so that the scraping blade 18 scrapes off the sundries on the side wall of the filter holes to improve the cleaning effect.

[0028] A feed inlet 1.1 is provided in the middle of the left side of the housing 1, and an inclined feed pipe 20 communicating with the feed inlet 1.1 is provided inside the housing 1.

[0029] A controller is also provided outside the housing 1 and is connected to each mechanism to control the operation of each mechanism.

[0030] In order to better illustrate the present invention, the following specifically describes its working process:

[0031] The waste oil from vehicle disassembly is fed into the box body 21 and then sent into the filter box 5 through the feed port 1.1 of the pretreatment tank 22. The second rotating motor 17 drives the filter box 5 to swing back and forth to filter the waste oil. After filtering for a period of time, the filter box 5 is cleaned. The cylinder 11 drives the support rod 12 to move downward, sending the second treatment plate 10 to the bottom of the filter box 5 until the cleaning head 13 is inserted into the filter holes. The second treatment plate 10 makes a circular motion, driving the cleaning head 13 at the bottom to make a circular motion in the filter holes, so that the scraping blade 18 scrapes off the sundries on the side walls of the filter holes. The cleaning mechanism moves left and right, driving the second treatment plate 10 to move left and right to clean the filter holes at various positions. After the cleaning of the bottom filter holes is completed, the rotating rod 8 flips, and the first treatment plate 9 flips to the lower side, see Figure 5 , and then the first treatment plate 9 moves back and forth to clean the filter holes on the front and rear sides of the filter box 5. After the cleaning is completed, the cleaning mechanism moves into the cleaning chamber 4. The cleaning chamber 4 is filled with clean water. While the cleaning mechanism moves up and down and sways back and forth, the cleaning head 13 can be used for cleaning to wash down the sundries.

[0032] The wastewater in the cleaning chamber 4 is discharged into the sedimentation tank 23 for the separation of sundries and wastewater. The separated wastewater is pumped into the oil-water separation tank 24 to further remove the floating oil, improve the oil recovery rate, and reduce the operating pressure of the subsequent process. Then the wastewater is sent into the adjustment tank 25, where the pH is adjusted in the dosing reaction area, and a demulsifier, PAC, and PAM are added to form large particle flocs from the emulsion and soluble pollutants. Through the action of the tiny bubbles generated by pressure dissolved air flotation, most of the COD and SS in the water are removed. The effluent from the air flotation enters the A / O biochemical treatment tank 26. By the action of bacteria such as anaerobic bacteria, facultative bacteria, and aerobic bacteria, the refractory organic matter in the wastewater is converted into easily degradable organic matter, and the organic matter is further decomposed. The treated wastewater can then be discharged into the discharge channel.

Those skilled in the art should understand that the above embodiments do not limit the present utility model in any form. Any technical solutions obtained by using equivalent replacements or equivalent transformations fall within the protection scope of the present utility model.
