[0027] The water filtering mechanism 3 includes a filtering hopper 31. Inside the filtering hopper 31, an upper punching filter plate 32 is fixedly connected. Horizontally arranged chute grooves 33 are symmetrically formed inside the filtering hopper 31. A long threaded rod 34 is rotatably connected inside one set of the chute grooves 33. A driving motor 35 is fixedly connected to the outside of the filtering hopper 31. A moving cross bar 36 is arranged inside the filtering hopper 31. Chute sliders 37 are fixedly connected to both ends of the moving cross bar 36. The chute sliders 37 are adapted to the horizontally arranged chute grooves 33. A threaded hole adapted to the long threaded rod 34 is formed on the side of one set of chute sliders 37 close to the long threaded rod 34. A cleaning scraping plate 38 is fixedly connected below the moving cross bar 36. The cleaning scraping plate 38 is closely attached to the upper part of the upper punching filter plate 32. Two sets of top columns 313 are fixedly connected to the side of the moving cross bar 36. A first fixing plate 39 is fixedly connected below the filtering hopper 31. A through hole is formed inside the first fixing plate 39, and a short threaded rod 310 is rotatably connected inside it. A lower punching sliding plate 312 is arranged below the filtering hopper 31. A slide bar is fixedly connected to the upper part of the lower punching sliding plate 312. A chute adapted to the slide bar fixedly connected to the upper part of the lower punching sliding plate 312 is formed below the upper punching filter plate 32, enabling the lower punching sliding plate 312 to slide back and forth along the direction of the short threaded rod 310 below the upper punching filter plate 32. A second fixing plate 311 is fixedly connected below the lower punching sliding plate 312. A threaded hole adapted to the short threaded rod 310 is formed on the side of the second fixing plate 311. The second fixing plate 311 is threadedly connected to the short threaded rod 310 through the threaded hole formed on its side. Punching holes penetrating to the lower part of themselves are formed on both the upper part of the lower punching sliding plate 312 and the upper punching filter plate 32. And in the initial state, the positions of the lower punching sliding plate 312 and the upper punching filter plate 32 coincide. The short threaded rod 310 penetrates through the water tank housing 1 to its outside.

[0028] Refer to Figure 2 and Figure 5, the sediment impurity storage mechanism 7 includes a storage box 71. A storage cavity 72 is provided inside the storage box 71. The upper end of the side of the storage cavity 72 penetrates to the outside of the storage box 71, and the size of the opening where the upper end of the side of the storage cavity 72 penetrates to the outside of the storage box 71 is adapted to the size of the rotating baffle 73. A rotating baffle 73 is rotatably connected inside the storage cavity 72. Two groups of support springs 74 are fixedly connected to the storage cavity 72. One end of the support spring 74 is fixedly connected inside the storage cavity 72, and the other end of the support spring 74 is fixedly connected to the rotating baffle 73. An opening penetrating to the processing chamber 2 is provided on the outside of the water tank housing 1. The opening on the outside of the water tank housing 1 corresponds to the opening on the side of the storage cavity 72, and the opening of the storage cavity 72 is slightly lower than the opening on the outside of the water tank housing 1. When the sediment impurity storage mechanism 7 is fixed to the water tank housing 1, the rotating baffle 73 is blocked by the outside of the water tank housing 1. Under the support of the support spring 74, the storage cavity 72 is not communicated with the processing chamber 2 at this time. At this time, sewage can be put into the processing chamber 2 through the water inlet pipe 5, and after being filtered by the water filtering mechanism 3, it reaches the purified water storage chamber 4. When it is needed to be taken, it is taken through the water outlet pipe 6. By rotating the short screw rod 310, the overlapping degree of the punching of the lower punching slide plate 312 and the upper punching filter plate 32 can be adjusted, so as to accurately filter sediment particles of different particle sizes. When the filtering is completed, the sediment impurities deposited on the upper punching filter plate 32 can be cleaned. At this time, the driving motor 35 is started to drive the long screw rod 34 to rotate. At this time, the moving cross bar 36 drives the cleaning scraper 38 to scrape and clean the upper punching filter plate 32. When it moves to a suitable position, the ejector post 313 will push the rotating baffle 73 upward into the storage cavity 72. At this time, the storage cavity 72 is communicated with the processing chamber 2, so that the impurity sediment cleaned by the cleaning scraper 38 can be pushed and cleaned into the opened storage cavity 72. After the cleaning is completed, the driving motor 35 drives the long screw rod 34 to rotate, the moving cross bar 36 drives the cleaning scraper 38 to return to the initial position, the rotating baffle 73 returns to the initial position, and the storage cavity 72 continues to maintain a sealed state to prevent water from entering when filtering sewage.

[0029] The working principle of the present utility model is as follows: After the sewage enters the processing chamber 2, it is first preliminarily filtered by the water filtering mechanism 3. The water filtering mechanism 3 intercepts most of the larger sediment particles and other impurities through the densely distributed punching holes on the upper punching filter plate 32. By rotating the short screw rod 310, the overlapping degree of the punching holes between the lower punching slide plate 312 and the upper punching filter plate 32 can be flexibly adjusted. This function allows users to accurately control the filtering accuracy according to the specific situation of the sewage, effectively remove sediment particles of different particle sizes, and improve the flexibility and adaptability of filtering;

[0030] When a certain amount of sediment impurities accumulate on the upper punching filter plate 32 during the filtering process, the water inlet is stopped at this time, and the driving motor 35 is started to drive the long threaded rod 34 to rotate, thereby driving the moving cross bar 36 and the cleaning scraper 38 thereon to move along the surface of the upper punching filter plate 32 for scraping and cleaning. During this process, through the action of the top column 313, the rotating baffle 73 is lifted, so that the storage cavity 72 is communicated with the treatment chamber 2, and the sediment impurities swept down are smoothly pushed into the storage cavity 72 by the cleaning scraper 38, realizing the centralized collection and treatment of impurities;

[0031] After the cleaning is completed, the driving motor 35 rotates in the reverse direction to drive the cleaning scraper 38 back to the initial position. At the same time, the rotating baffle 73 automatically resets under the action of the support spring 74 to re-close the opening of the storage cavity 72 to prevent water from entering during the treatment of sewage. This design ensures the sealing and stability of the water tank during the filtering process;

[0032] The purified water filtered by the water filtering mechanism 3 finally flows into the purified water storage chamber 4 for storage. When it is necessary to take water, just open the water outlet pipe 6 to conveniently obtain the filtered purified water. This process not only ensures the cleanliness of the water used by the shield machine, but also improves the utilization efficiency of water resources.

[0033] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
