A solenoid valve 410 is installed at the top of the AC pipe 41, and the bottom end of the AC pipe 41 extends into the inner cavity of the filter drum 6. The filter drum 6 is configured in an inverted bucket shape and has an opening at the bottom. A stirring assembly for mixing the dispersant is installed inside the stirring drum 4. The stirring assembly includes a stirring motor 1, a stirring blade 2, and a fixing frame 3. The fixing frame 3 is fixedly installed on the outer wall of the stirring drum 4, and the stirring motor 1 is fixedly installed at the top of the fixing frame 3. The stirring blade 2 is installed at the output end of the stirring motor 1 and extends into the inner cavity of the stirring drum 4.

[0023] The mixing cylinder 4 and the filter cylinder 6 are both fixedly mounted on the main frame 5. The main frame 5 fixes the mixing cylinder 4 and the filter cylinder 6 in an alternating manner, with the mixing cylinder 4 positioned diagonally above the filter cylinder 6. A sludge collection cylinder 61 is fixedly mounted on the side of the filter cylinder 6. A filter assembly is installed inside the filter cylinder 6. The filter assembly intercepts large particles in the mixed dispersant. The filter assembly includes a docking frame 11, a connecting cylinder 14, and a filter screen 15. The top of the connecting cylinder 14 is fixedly connected to the bottom of the right folding rod 13. A filter screen 15 is fixedly mounted in the middle of the inner cavity of the connecting cylinder 14. One end of the connecting cylinder 14 is attached to the inner wall of the filter cylinder 6. The top of the right folding rod 13 is fixedly connected to the output end of the switching servo motor 10. The switching servo motor 10 is fixedly mounted on the top of the left folding rod 7. A docking frame 11 is fixedly mounted on one end of the connecting cylinder 14.

[0024] A left-hand folding rod 7 is fixedly installed at the top of the filter cylinder 6. A backflushing assembly is installed at the top of the left-hand folding rod 7. The backflushing assembly periodically intercepts and discharges material from the filter cylinder. The backwash assembly includes a backwash box 18, a docking folding tube 17, a water inlet pipe 16, and a retaining cam 9. The backwash box 18 is movably inserted into the docking frame 11. The top of the backwash box 18 is fixedly connected to one end of the docking folding tube 17. A receiving groove 12 is provided on the side of the right folding rod 13. The bottom of the receiving groove 12 is fixedly connected to one end of the elastic column 19. The other end of the elastic column 19 is fixedly set at the bottom of the docking folding tube 17. The backwash box 18 and the filter screen 15 have holes in a circular array on their sides. Both the backwash box 18 and the docking folding tube 17 are hollow. A water inlet pipe 16 is fixedly set on the side of the docking folding tube 17. The retaining cam 9 is concentrically set with the output end of the switching servo motor 10. The outer wall of the retaining cam 9 is fixedly connected to one end of the L-shaped rod 8. The other end of the L-shaped rod 8 is fixedly set at the bottom of the left folding rod 7. The bottom of the retaining cam 9 is provided with an inclined surface, which has a highest and lowest end.

[0025] The model of the switching servo motor 10 is selected as MR-JET, which comes with a PLC controller. The solenoid valve 410 is connected to the PLC controller. When the switching servo motor 10 drives the connecting tube 14 away from one end of the AC pipe 41 and aligns with the sludge receiving tube 61, the solenoid valve 410 will close, and the water inlet pipe 16 will be connected to the external cleaning water.

[0026] The vertical height of the docking frame 11 is set to be long enough. When the elastic column 19 is at its original length and the recoil box 18 is at its highest position, it is still closed by the docking frame 11. However, at this time, the recoil box 18 opens the connecting tube 14.

[0027] The specific implementation steps and principles of this utility model are as follows:

[0028] Workers put the dispersant raw materials and solvent into the mixing drum 4. After the dispersant is pre-mixed by the stirring motor 1 driving the stirring blade 2, when the bottom of the connecting drum 14 is aligned with the bottom of the AC pipe 41, the solenoid valve 410 opens and the mixture flows through the filter screen 15. Large particles are intercepted by the filter screen 15. At this time, the elastic column 19 is at its original length, which drives the backwash box 18 to the highest position. At this time, the backwash box 18 does not disconnect the connecting drum 14, and the filtered liquid flows into the filter drum 6, which abuts against the top of the connecting tube 17 and the bottom of the abutting cam 9.

[0029] When the switching servo motor 10 reaches the start-up setting time, the switching servo motor 10 rotates, driving the connecting cylinder 14 to leave one end of the AC pipe 41 and align with the sludge receiving cylinder 61. During this process, the solenoid valve 410 will close, and the connecting folding pipe 17 will be pressed down by the bottom surface of the supporting cam 9. The backwash box 18 will move down to its limit position. At this time, the connecting cylinder 14 is isolated, and the water inlet pipe 16 will pump enough cleaning water into the backwash box 18. The backwash box 18 will backwash the filter screen 15, and the intercepted material will be discharged from the sludge receiving cylinder 61.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
