[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] An impurity separation device for solvent refining of waste lubricating oil, such as Figures 1 to 5 As shown, the system includes a separation cylinder 1, a support member installed at the bottom of the separation cylinder 1, and a maintenance cover plate 4 fixed to one end of the separation cylinder 1 by bolts. A rotating scraper 13 is rotatably connected between the separation cylinder 1 and the maintenance cover plate 4, and a separation filter screen 12 is welded to the surface of the rotating scraper 13. A drive motor 7 is fixed to one side of the outer wall of the separation cylinder 1 by bolts, and the output end of the drive motor 7 is connected to one end of the rotating scraper 13 by a coupling. A cleaning section for cleaning the separation filter screen 12 and the rotating scraper 13 is installed at the top of the separation cylinder 1.

[0028] In the initial stage, the position of the separation filter screen 12 and the rotating scraper 13 is adjusted by the driving motor 7, so that the separation filter screen 12 and the rotating scraper 13 are in a horizontal state. When the impurities in the waste lubricating oil solvent need to be separated, the waste lubricating oil solvent is introduced into the separation cylinder 1. The end of the rotating scraper 13 and the inner wall of the circumference of the separation cylinder 1 are in close contact with each other. The waste lubricating oil solvent is filtered by the separation filter screen 12. After filtration, the impurities are intercepted by the separation filter screen 12. The filtered waste lubricating oil solvent enters the bottom of the separation cylinder 1 through the separation filter screen 12.

[0029] During the separation process, the separation filter screen 12 and the rotating scraper 13 are driven to reciprocate at a certain angle by the driving motor 7. In the process of reciprocation, the waste lubricating oil solvent is constantly shaken, thereby accelerating the separation rate of the impurities in the waste lubricating oil solvent.

[0030] When the separation of the waste lubricating oil solvent is completed and the impurities intercepted on the separation filter screen 12 need to be cleaned, the separation filter screen 12 and the rotating scraper 13 are driven by the driving motor 7 to rotate 180 degrees from the initial stage. The separation filter screen 12 is inverted. Then the separation filter screen 12 and the rotating scraper 13 are driven to reciprocate, so that the impurities on the separation filter screen 12 fall into the bottom of the separation cylinder 1 under the action of gravity and shaking, thereby achieving the cleaning of the impurities intercepted on the separation filter screen 12.

[0031] At the same time, when the edge of the rotating scraper 13 rotates along the inner wall of the circumference of the separation cylinder 1, the rotating scraper 13 scrapes off the impurities attached to the inner wall of the circumference of the separation cylinder 1.

[0032] Further, the cleaning part includes a frame 6 and an electric telescopic rod 11. The frame 6 is fixed to the top outer wall of the separation cylinder 1 by bolts. The electric telescopic rod 11 is fixed to the top outer wall of the frame 6 by bolts. The output end of the electric telescopic rod 11 is fixed with a driving plate 16 by a pin. The bottom of the driving plate 16 is provided with a nozzle assembly.

[0033] By providing the electric telescopic rod 11, the height of the nozzle assembly can be adjusted. When a small amount of impurities attached to the separation filter screen 12 need to be cleaned, high-pressure water flow is sprayed by the nozzle assembly. At the same time, the separation filter screen 12 and the rotating scraper 13 are driven to rotate by the driving motor 7, so that the high-pressure water flow sprayed by the nozzle assembly can clean different positions on the separation filter screen 12 and the rotating scraper 13.

[0034] Further, the nozzle assembly includes a spray pipe 17, a nozzle body 18, and a vertical plate 20. The vertical plate 20 is welded to the bottom of the driving plate 16. The spray pipe 17 is rotatably connected to the inner wall of the through hole on the surface of the vertical plate 20. The nozzle body 18 is welded to the outer wall of the spray pipe 17. One end of the spray pipe 17 is welded with a flange plate 19.

[0035] The flange 19 is connected with the soft water pipe during cleaning, so that the water flows out through the nozzle body 18 after being pressurized by the water pump, thereby cleaning the separation filter screen 12 and the rotating scraper 13.

[0036] The gear 15 is connected to the circumferential outer wall of the spray pipe 17 by a key, and the rack 14 engaged with the gear 15 is fixed to the inner wall of one side of the separation cylinder 1 by a screw;

[0037] The rack 14 and the gear 15 are arranged to enable the nozzle body 18 to rotate during the up-and-down movement, so that the spray direction of the nozzle body 18 can be adjusted within a certain range, thereby improving the cleaning range.

[0038] The support includes a bracket 2 and a base 3, the bracket 2 is welded to the bottom of the separation cylinder 1, and the base 3 is welded to the bottom of the bracket 2;

[0039] The bracket 2 and the base 3 are arranged to support the separation cylinder 1.

[0040] The valve one 5 is fixed to the top side of the separation cylinder 1 by a bolt, the three-way pipe 10 is fixed to the bottom of the separation cylinder 1 by a bolt, the valve three 9 is fixed to the bottom of the three-way pipe 10 by a bolt, and the valve two 8 is fixed to the side of the three-way pipe 10 by a bolt;

[0041] When the valve three 9 is closed and the valve two 8 is opened, the waste lubricating oil solvent filtered by the separation filter screen 12 is discharged through the valve two 8, and when the valve three 9 is opened and the valve two 8 is closed, the waste liquid after cleaning can be discharged by the valve three 9.

[0042] Working principle: first, the waste lubricating oil solvent to be filtered is introduced into the separation cylinder 1 through the valve one 5, the impurities in the waste lubricating oil solvent are filtered and retained by the separation filter screen 12, the filtered waste lubricating oil solvent falls to the bottom of the separation cylinder 1, after the impurities are separated, the valve two 8 is opened, so that the separated waste lubricating oil solvent is discharged through the valve two 8, then the valve three 9 is opened and the valve two 8 is closed, the separation filter screen 12 and the rotating scraper 13 are driven to rotate by the driving motor 7, the separation filter screen 12 is inverted so that the impurities filtered and retained on the separation filter screen 12 fall under the action of its own gravity, then the separation filter screen 12 and the rotating scraper 13 are cleaned by the nozzle assembly, thereby cleaning the separation filter screen 12 and the rotating scraper 13.

[0043] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
