[0025] As a technical optimization solution of the present utility model, electromagnet blocks one 52 are inlaid at the centers of both ends of the top of the filter screen frame 51. A clamping block 53 is clamped inside the clamping groove 54. An electromagnet block two 58 is inlaid at the top of the clamping block 53. A storage frame 56 is jointly connected between the two clamping blocks 53. A notch 59 which is used in cooperation with the arc-shaped isolation bar 55 is opened on one side of the inner wall of the storage frame 56. Through the cooperation of the clamping block 53 and the clamping groove 54, the storage frame 56 can be positioned, facilitating the installation of the storage frame 56.

[0026] As a technical optimization solution of the present utility model, a filter screen is inlaid at the bottom of the inner wall of the storage frame 56, and the top of the storage frame 56 and the top of the filter screen frame 51 are on the same plane.

[0027] As a technical optimization solution of the present utility model, electromagnetic valves are installed on the outer discharge pipe 11, the pipeline at the liquid inlet end of the liquid extraction pump 12 and the sewage suction pipe 4. A support plate 8 is sleeved on the outer wall of the liquid spraying pipe 13; the bottom of the support plate 8 is connected to the top of the top plate 28.

[0028] As a technical optimization solution of the present utility model, the four positioning blocks 21 are respectively connected to the two sides of the top ends of both ends of the sedimentation tank 1. A sliding rod 22 is connected between the two positioning blocks 21. A linear motor 25 is sleeved on the outside of the sliding rod 22.

[0031] When the utility model is in use, during the process of sludge entering the sedimentation tank 1, it first falls on the top of the filter mesh frame 51. The filter mesh frame 51 is used to filter the garbage and large impurities in the sludge. During the sludge filtration period, the external control end of the pretreatment mechanism controls the linear motor 25 to reciprocate left and right outside the sliding rod 22. When the linear motor 25 moves to the right, the telescopic end of the electric telescopic rod two 26 extends, so that the bristles at the bottom of the cleaning brush plate 27 contact the filter mesh frame 51, and the garbage on the top of the filter mesh frame 51 is cleaned into the storage frame 56. The storage frame 56 is used to temporarily store the garbage and large impurities in the sludge. Subsequently, the linear motor 25 moves to the left. At this time, the telescopic end of the electric telescopic rod two 26 contracts, and so on to clean the top of the filter mesh frame 51. When the injection amount of sludge in the sedimentation tank 1 reaches the set requirement, the sludge entering the sedimentation tank 1 is stopped. After the sludge in the sedimentation tank 1 is settled, the solenoid valve on the sewage discharge pipe 3 and the external sludge suction pump connected to the sewage discharge pipe 3 are opened to pump out the sludge in the sedimentation tank 1. After the sludge is pumped out, the solenoid valve is closed. At this time, the sedimentation tank 1 stores the settled water. The liquid extraction pump 12 and the solenoid valve on its liquid inlet end are opened. At this time, water sprays out from the nozzle 6. The linear motor 25 is controlled to move left and right outside the sliding rod 22, and the filter mesh frame 51 is flushed with the water sprayed out from the nozzle 6. During the flushing process, the telescopic end of the electric telescopic rod two 26 is always in the extended state, and the bristles at the bottom of the cleaning brush plate 27 are used to clean the mesh holes of the filter mesh frame 51. After cleaning, the liquid extraction pump 12 and the solenoid valve on the liquid inlet end are closed, and the solenoid valve on the external discharge pipe 11 is opened to discharge the water. If it is necessary to replace the filter mesh frame 51, the linear motor 25 moves to the center outside the sliding rod 22. The telescopic end of the electric telescopic rod one 24 contracts, and the telescopic end of the electric telescopic rod two 26 extends. The electromagnet block one 52 and the electromagnet block two 58 are correspondingly energized to make them adsorb. Subsequently, the telescopic end of the electric telescopic rod one 24 extends, and the telescopic end of the electric telescopic rod two 26 contracts, lifting the filter mesh frame 51 from the inside of the sedimentation tank 1. The linear motor 25 moves to the right to drive the filter mesh frame 51 to move to the right. Subsequently, the electromagnet block one 52 and the electromagnet block two 58 are powered off and separated, and the filter mesh frame 51 and the storage frame 56 are removed and the inside of the storage frame 56 is cleaned. Finally, a new filter mesh frame 51 is replaced and each component is reset in sequence. Further, the storage frame 56 can also be directly taken out for cleaning or replacement, and the removal steps are similar to the above.
