Wastewater is discharged into the tank 1 and sedimentation tank 2 for sedimentation. Impurities settle to the bottom of the sedimentation tank 2. When cleaning impurities, the sludge pump 3 is controlled to directly discharge the impurities from the bottom of the sedimentation tank 2, eliminating the need for manual retrieval tools. This makes the operation convenient and quick, reducing the workload of the operator and facilitating the direct discharge of impurities. A filter plate 8 is installed to filter the water source, preventing impurities from entering the drain pipe 7 and ensuring the cleanliness of the discharged water source.

[0022] Please see Figure 3 The crushing mechanism 9 includes a fixed plate 90, which is fixedly connected to the inner wall of the box 1 on both the front and rear sides. A motor 91 is fixedly connected to the bottom of the fixed plate 90, and a vertical rod 92 is fixedly connected to the shaft of the motor 91. Crushing blades 93 are fixedly connected to the surface of the vertical rod 92. By setting up the fixed plate 90, motor 91, vertical rod 92 and crushing blades 93, the crushing blades 93 can be rotated to crush large impurities in the sedimentation hopper 2 and the inner cavity of the box 1, so as to avoid large impurities clogging the pipes and sludge pump 3. After the impurities are crushed, they can be discharged quickly.

[0023] Please see Figure 3 The bottom of the vertical rod 92 extends into the inner cavity of the sedimentation hopper 2. A spiral blade 94 is fixedly sleeved on the bottom of the surface of the vertical rod 92. By setting the spiral blade 94, impurities are conveyed downwards, which facilitates the discharge of impurities.

[0024] Please seeFigure 1 The top of the filter plate 8 passes through the housing 1 and is fixedly connected to a sealing plate 10. A handle is fixedly connected to the top of the sealing plate 10. By setting the sealing plate 10 and the handle, it is easy to move the handle upwards to disassemble the filter plate 8, which facilitates the cleaning and replacement of the filter plate 8.

[0028] When in use, municipal sewage enters the inner cavity of the tank 1 through the inlet pipe 5. Impurities in the water settle at the bottom of the inner cavity of the sedimentation hopper 2. The water source above enters the inner cavity of the drain pipe 7 after being filtered by the filter plate 8. The filter plate 8 blocks impurities in the water source from entering the drain pipe 7.

[0029] When discharging impurities from the inner cavity of sedimentation hopper 2, the motor 91 is controlled to drive the vertical rod 92, the crushing blade 93 and the spiral blade 94 to rotate. The crushing blade 93 crushes the impurities in the inner cavity of sedimentation hopper 2, and the spiral blade 94 conveys the crushed impurities downward. The sewage in the inner cavity of sedimentation hopper 2 is discharged through the sludge pump 3 and the sewage pipe 4 by controlling the operation of the sludge pump 3.

[0030] Move the pressure block 13 upwards to move it away from the slot 12, rotate the pressure block 13 to separate it from the sealing plate 10, move the sealing plate 10 upwards to move the filter plate 8 upwards, and disassemble and clean the filter plate 8.

[0031] In summary, this municipal water supply project filtration device, by setting up a housing 1, sedimentation hopper 2, sludge pump 3, sewage pipe 4, liquid inlet pipe 5, connecting pipe 6, and drainage pipe 7, solves the problem that when cleaning impurities, it is cumbersome, time-consuming, and labor-intensive to remove impurities from the filter box after disassembling the filter screen, which increases the workload of the operator and makes it impossible to directly discharge impurities.
