A water tank 18 is fixedly connected to the rear side of the box body 1. A water pump 19 is fixedly connected to the top of the water tank 18. The filter mechanism 8 includes an installation frame 12. The installation frame 12 is fixedly installed on both sides of the bottom of the flow guide frame 7. Fixed frames 13 are fixedly connected to the opposite sides of the two installation frames 12. An installation plate 17 is movably connected to the inner cavity of the installation frame 12. Filter grilles 11 are fixedly installed on the opposite sides of the two installation plates 17. By providing the discharge pipeline 5, the separated sundries can be guided, so that the equipment can discharge the sundries.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 , a spring 16 is fixedly connected to the inner cavity of the fixed frame 13. Positioning plug boards 14 are fixedly connected to the opposite sides of the two springs 16. Guide pulling plates 15 are fixedly connected to the opposite sides of the two positioning plug boards 14. By providing the positioning plug boards 14, they can be inserted into the installation plate 17 to position the installation plate 17, preventing the filter grilles 11 from sliding out of the installation frame 12 randomly.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 , installation sliding holes are formed in the top of the filter grilles 11. Connecting card plates 10 are fixedly connected to the inner cavity of the flow guide frame 7. By providing the connecting card plates 10, they can cooperate with the installation sliding holes to position and install the filter grilles 11, thereby increasing the installation stability of the filter grilles 11.

[0023] Please refer to Figure 4, a motor 21 is fixedly connected to the rear side of the feeding housing 2. The output end of the motor 21 penetrates into the inner cavity of the feeding housing 2 and is fixedly connected to a crushing rotating shaft 22. Through the cooperation of the motor 21 and the crushing rotating shaft 22, solid sundries can be crushed to avoid the sundries being too large.

[0024] Please refer to Figure 1 , a connecting pipe 20 is communicated with the liquid outlet end of the water pump 19. The top end of the connecting pipe 20 is communicated with the flushing spray plate 3, and the liquid inlet end of the water pump 19 is communicated with the water tank 18.

[0025] Please refer to Figure 4 , a scale is inlaid and installed on the rear side of the water tank 18. An inlet valve and a drain valve are respectively communicated with the left side of the water tank 18.

[0026] Please refer to Figure 2 and Figure 3 , support legs are fixedly connected to both sides of the box body 1.

A silt suction pump 23 is communicated with the top of the feeding housing 2.

[0027] During use, the user first conveys the water liquid into the water tank 18 through the inlet valve. Then the user conveys the river silt into the feeding housing 2 through the silt suction pump 23. When the silt enters the feeding housing 2, the user starts the motor 21 so that the output end of the motor 21 can drive the crushing rotating shaft 22 to crush the sundries in the silt. Then the silt will fall into the separation mesh frame 4 for solid-liquid separation. The separated solid sundries will be guided through the separation mesh frame 4 into the discharge pipeline 5 to discharge the sundries. During separation, the user regularly starts the water pump 19 so that the water pump 19 can convey the water liquid in the water tank 18 into the flushing spray plate 3, and the flushing spray plate 3 can flush the inside of the separation mesh frame 4 to prevent sundries from remaining in the separation mesh frame 4. At the same time, the separated water liquid will be guided by the flow guiding cover 6 into the filtering mechanism 8. Then the filtering grille 11 will filter the water liquid. The filtering grille 11 will filter the sediment in the water liquid. Then the user opens the drain valve 9 to discharge the filtered water liquid. At the same time, during use, the user can regularly replace or clean the filtering grille 11. The user pulls the positioning plug board 14 through the guiding pull board 15 to release the limit on the filtering grille 11. Then the user pulls the filtering grille 11 forward to remove the filtering grille 11 from the flow guiding frame 7, so that the staff can replace or clean the filtering grille 11 to prevent the filtering effect of the filtering grille 11 from decreasing.

[0028] In summary, the hydraulic engineering river dredging device for solid-liquid separation solves the problems that the sludge cannot be subjected to solid-liquid separation treatment, which is inconvenient for transportation, and most of them do not have the function of crushing the sludge, resulting in a large amount of debris remaining in the sludge, through the cooperation of the box body 1, the feeding shell 2, the flushing spray plate 3, the separation mesh frame 4, the discharge pipeline 5, the guide hood 6, the guide frame 7, the filtering mechanism 8, the drain valve 9 and the connecting clamping plate 10.
