[0026] As Figures 1 to 6 shown, the present application provides a silt filtering device for water conservancy projects.

[0027] The system includes an inlet tank 2, a first hopper 12 fixedly connected to the lower part of the inlet tank 2, a sedimentation tank 1 fixedly connected to the lower part of the first hopper 12, a pre-filtration mechanism 9 inserted into the bottom of the first hopper 12, a second hopper 14 fixedly connected to the lower part of the sedimentation tank 1, the pre-filtration mechanism 9 being a rectangular cylinder, having several first filter holes 91 evenly distributed on the pre-filtration mechanism 9, a handle 92 welded to the upper part of the pre-filtration mechanism 9, a stainless steel filter plate 15 fixedly connected to the upper part of the second hopper 14, a rectangular hole 16 being opened in the center of the stainless steel filter plate 15, and a sand discharge pipe 11 welded to one side of the second hopper 14.

[0028] A first flange is fixedly connected to the sand discharge pipe 11. The first flange is connected to a sludge pump through a connecting pipe. A support rod 3 is welded to the water inlet tank 2.

[0029] A first flange is fixedly connected to the sand discharge pipe 11, a design that facilitates quick and reliable connection with other components. The first flange is connected to the sludge pump via a high-strength, corrosion-resistant connecting pipe, ensuring efficient pumping of sludge and reducing sediment accumulation within the system, preventing blockages caused by sludge buildup. Furthermore, support rods 3 are welded to the inlet tank 2. These support rods not only enhance the structural stability of the inlet tank 2 but also effectively disperse the impact force generated during water intake, protecting the integrity of the entire system. They also provide additional mounting points for attaching subsequent equipment or maintenance tools.

[0030] The size of the rectangular hole 16 is slightly smaller than the size of the bottom surface of the pre-filter mechanism 9, which can be placed on the upper part of the stainless steel filter plate 15.

[0031] The rectangular hole 16 is slightly smaller than the bottom surface of the pre-filter mechanism 9. This design allows the pre-filter mechanism 9 to be securely placed on top of the stainless steel filter plate 15 without easily sliding or shifting, ensuring stability and consistency during the filtration process. When cleaning or replacing the pre-filter mechanism 9, operators can easily lift the device, remove any adhering sediment, and then reposition it. This feature greatly simplifies the maintenance process, reduces downtime, and indirectly extends the service life of the entire system by minimizing interference with other components.

[0032] A first connecting box 4 is welded to the right side of the sedimentation tank 1. A second filter tank 6 is connected to the right side of the first connecting box 4. A support leg 10 is welded to the lower part of the second filter tank 6.

[0033] A first connecting box 4 is welded to the right side of the sedimentation tank 1. This design helps to smoothly transition the water flow and avoid turbulence causing the sediment to remix. A second filter tank 6 is connected to the right side of the first connecting box 4, ensuring that the pre-treated water can flow smoothly into the next stage of the filtration system. To further enhance the stability of the second filter tank 6, support legs 10 are welded to its lower part. These support legs 10 not only improve the overall structural stability but also absorb ground vibrations to a certain extent, protecting the internal filter components from external factors and ensuring long-term stable operation.

[0034] A filter screen device 5 is inserted into the upper part of the second filter tank 6. The filter screen device 5 includes a frame 51, and a top plate 52 is fixedly connected to the upper part of the frame 51.

[0035] A filter screen device 5 is inserted into the upper part of the second filtration tank 6. This device includes a sturdy frame 51, and a top plate 52 is fixedly connected to the upper part of the frame 51. This structure ensures the strength of the filter screen device 5 while facilitating disassembly and cleaning. The design of the top plate 52 is not only aesthetically pleasing but also provides the operator with a safe operating platform, allowing for inspection or maintenance without damaging the filter layer 53. The filter layer 53 is fixedly connected inside the frame 51. This filter medium effectively removes fine particles from the water, significantly improving water quality and meeting higher purification standards.

[0036] The top plate 52 is connected to the second filter pool 6 by bolts, and the filter layer 53 is fixedly connected inside the frame 51.

[0037] The top plate 52 is connected to the second filter tank 6 by bolts. This detachable design greatly facilitates the maintenance and replacement of the filter screen device 5. In actual operation, the entire filter screen device 5 can be removed simply by loosening a few bolts for thorough cleaning or replacement of the filter layer 53. This method not only saves a significant amount of manpower and time costs but also reduces efficiency degradation caused by prolonged use, ensuring the durability and reliability of the filtration effect.

[0038] A second connecting box 7 is welded to the right side of the second filter tank 6, and a clear water tank 8 is connected to the right side of the second connecting box 7.

[0039] The second connecting tank 7 is welded to the right side of the second filtration tank 6. This design is also intended to achieve a smooth water flow transition, minimizing energy loss and water disturbance. A clear water tank 8 is connected to the right side of the second connecting tank 7. This connection must be seamless to avoid any potential leakage risks. The clear water tank 8 serves as the final storage unit, storing the high-quality clear water obtained after multi-stage filtration, ready for further discharge or reuse.

[0040] A mounting plate 18 is connected to the right side of the clear water tank 8. A drain pipe 17 is connected to the mounting plate 18. One end of the drain pipe 17 is connected to a second flange, and the other end of the drain pipe 17 is connected to a bend 13.

[0041] A mounting plate 18 is connected to the right side of the clear water tank 8, and a drain pipe 17 is connected to the mounting plate 18. One end of the drain pipe 17 is equipped with a second flange for easy connection to other piping systems. In addition, the bend 13 can be adjusted in angle according to specific needs to adapt to different installation environments and drainage requirements, increasing the system's flexibility and applicability.

[0042] Working principle: First, water containing a large amount of sediment enters the inlet tank 2, which is connected to the first hopper 12 at the bottom, allowing the water to flow into the hopper. A pre-filtration mechanism 9, rectangular in shape, is inserted into the bottom of the first hopper 12, with several evenly distributed first filter holes 91. As water flows through these filter holes, larger sediment particles are intercepted, achieving preliminary filtration. A handle 92 is welded to the upper part of the pre-filtration mechanism 9, facilitating the operator to lift and empty the collected sediment, reducing pressure on subsequent filtration components.

[0043] After preliminary filtration, the water flows into the stainless steel filter plate 15 and the sedimentation tank 1. The stainless steel filter plate 15 has a rectangular hole 16 in the center, slightly smaller than the bottom size of the pre-filtration mechanism 9, allowing the pre-filtration mechanism 9 to be stably placed on top of it. This design not only optimizes the water flow direction but also improves the secondary filtration efficiency. At the same time, the sand discharge pipe 11 is located on one side of the second hopper 14 to discharge the settled silt and maintain the cleanliness of the system.

[0044] The water, filtered by the stainless steel filter plate 15, then enters the first connecting tank 4 and flows to the second filtration tank 6. The second filtration tank 6 has support legs 10 welded to its lower part to ensure its stability. Inside the second filtration tank 6, a filter screen device 5 is inserted, including a frame 51, a top plate 52, and a filter layer 53 fixed inside the frame 51. The filter layer 53 further removes fine particles from the water, improving water quality. The top plate 52 is connected to the second filtration tank 6 by bolts for easy disassembly and maintenance.

[0045] After fine filtration, the clean water flows into the clean water tank 8 through the second connecting box 7. Finally, the drain pipe 17 on the mounting plate 18 connected to the right side of the clean water tank 8 discharges the treated clean water. One end of the drain pipe 17 is connected to a second flange, and the other end is connected to a bend pipe 13. The second flange is used to connect a water pump to ensure the outlet water pressure.
