[0017] This utility model provides a high-efficiency sedimentation and separation device for water treatment, which has the following beneficial effects:
[0018] 1. By controlling the opening and closing of various valves on the inlet pipe, outlet pipe, sewage pipe, and water inlet pipe, wastewater undergoes filtration and separation inside the separation cylinder for water treatment. Simultaneously, clean water is delivered to the inside of the separation cylinder to be cleaned to spray and wash the separation screen.

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0027] like Figures 1 to 4 As shown in the figure, this utility model provides a high-efficiency sedimentation and separation device for water treatment, including two separation cylinders 1 and two separation screens 2 fixed inside the corresponding separation cylinders 1. The separation screens 2 are provided with separation holes for separating impurities. The bottom of the separation cylinder 1 is provided with a liquid inlet component and a sludge discharge component, and a liquid outlet component is provided on one side of the separation cylinder 1 and above the separation screens 2. Both the liquid inlet component and the liquid outlet component can control the liquid flow direction to realize the switching of operation between the two separation cylinders 1. A spray washing component is provided above each of the two separation screens 2 for cleaning the separation screens 2.
[0028] During operation, wastewater enters one of the separation cylinders 1 under the control of the inlet assembly. After being filtered by the separation screen plate 2, the clean water is discharged from the outlet assembly. When the separation screen plate 2 approaches saturation and becomes clogged, the system switches to the other separation cylinder 1 through the coordination of the inlet and outlet assemblies. Simultaneously, the clogged separation screen plate 2 is sprayed and washed, and the cleaned wastewater is discharged through the drain assembly. This allows for continuous operation and improves water treatment efficiency. By combining dual-cylinder switching, automatic spraying, and pipeline control, the system solves the problem of low efficiency when traditional separation devices are shut down for extended periods for cleaning, achieving uninterrupted operation and improving water treatment efficiency.
[0029] In some specific implementation plans, such as Figure 1 , Figure 2 and Figure 4 As shown, the liquid inlet assembly includes a main liquid inlet pipe 7 located on one side of the drain pipe 3 and two liquid inlet pipes 5 fixedly mounted on the main liquid inlet pipe 7. Each liquid inlet pipe 5 is fixedly connected to the corresponding drain pipe 3, and each liquid inlet pipe 5 is equipped with a valve 2. The liquid inlet pipe 5 is inclined upwards and is perpendicular to the drain pipe 3. The slight upward inclination of the liquid inlet pipe 5 prevents cleaning wastewater from falling into the liquid inlet pipe 5. The liquid outlet assembly includes a main liquid outlet pipe 8 located outside the separation cylinder 1 and two liquid outlet pipes 4 fixedly mounted on the main liquid outlet pipe 8. Each liquid outlet pipe 4 is fixedly connected to the corresponding separation cylinder 1, and each liquid outlet pipe 4 is equipped with a valve 3. The sewage discharge assembly includes a main sewage discharge pipe 6 and two sewage discharge pipes 3 fixedly mounted on the main sewage discharge pipe 6. Each sewage discharge pipe 3 is fixedly mounted at the bottom of the corresponding separation cylinder 1. The liquid inlet pipes 5 and the sewage discharge pipes 3 are connected to the separation cylinder 1. Furthermore, each sewage pipe 3 is equipped with a valve, and each valve is a solenoid valve, which facilitates automated control.
[0030] The inlet header 7 is used for the inlet of the water to be treated, the outlet header 8 is used for the discharge of the filtered and separated water, and the wastewater header 6 is used for the discharge of cleaning wastewater. When the water to be treated is filtered to separate impurities, the external water to be treated is transported to the inside of the inlet header 7 by a transfer pump. The water to be treated overflows into the separation cylinder 1 through the inlet pipe 5. After the impurities are separated by the separation screen plate 2, the filtered water is discharged into the outlet header 8 through the outlet pipe 4 for collection.
[0031] Under normal operating conditions, the separation screen 2 inside one separation cylinder 1 performs water treatment, while the separation screen 2 inside the other separation cylinder 1 simultaneously undergoes cleaning. By controlling the opening of valves 2 and 3 on the inlet pipe 5 and outlet pipe 4, and the closing of valve 1 on the drain pipe 3, the water to be treated is transported into the separation cylinder 1 undergoing water treatment and discharged through its outlet pipe 4. The inlet pipe 5 and outlet pipe 4 on the other separation cylinder 1 remain disconnected, and valve 1 on the drain pipe 3 remains open to facilitate subsequent rinsing.
[0032] In some specific implementation plans, such as Figure 3 As shown, the spray washing assembly includes a movable pipe 11 located above the separating screen plate 2, a drive assembly for rotating the movable pipe 11, a control assembly for moving the movable pipe 11 up and down, multiple nozzles 12 evenly fixed to the bottom of the movable pipe 11, a movable plate 10 located above the separating screen plate 2, a rotary joint 14, and a water supply pipe 13 fixed to the top of the rotary joint 14. The movable pipe 11 has an L-shaped structure, and the rotary joint 14 is fixed to the top of the movable pipe 11. The rotating end of the rotary joint 14 is fixed to the movable pipe 11, and the fixed end is fixed to the water supply pipe 13. The movable pipe 11 is rotatably connected to the movable plate 10, the drive assembly is located on the top of the movable plate 10, and the water supply assembly is located on the top of the separating cylinder 1.
[0033] The water delivery assembly delivers cleaning water into the water delivery pipe 13. The cleaning water is delivered into the movable pipe 11 through the rotary joint 14. The movable pipe 11 is rotatably connected to the movable plate 10. When the drive assembly drives the movable pipe 11 to rotate, the nozzle 12 can cover the entire cleaning range of the separation screen plate 2.
[0034] In some specific implementation plans, such as Figure 1 and Figure 4As shown, one end of the water supply pipe 13 extends to the outside of the separation cylinder 1 and is connected to the water supply assembly. A through groove 19 is opened inside the separation cylinder 1 and above the liquid outlet pipe 4. The water supply pipe 13 passes through the through groove 19 to ensure its free up and down movement. The water supply assembly includes a main water inlet pipe 9 fixed to the top of the separation cylinder 1 and two water inlet pipes 21 fixed to the main water inlet pipe 9. Each water inlet pipe 21 is connected to the corresponding water supply pipe 13 by a flexible hose 20, and each water inlet pipe 21 is equipped with a valve 4. The main water inlet pipe 9, water inlet pipe 21, flexible hose 20, water supply pipe 13, rotary joint 14, movable pipe 11 and nozzle 12 are interconnected.
[0035] The inlet header 9 is connected to an external water pump. The water pump delivers clean water from the outside through the inlet header 9, inlet pipe 21, and hose 20 to the inside of the water supply pipe 13, providing a cleaning water source for the nozzle 12. Furthermore, by controlling valve four on the inlet pipe 21, the on / off state of each inlet pipe 21 can be controlled to achieve the supply of cleaning water to different water supply pipes 13.
[0036] In some specific implementation plans, such as Figure 1 and Figure 3 As shown, the drive assembly includes a motor 15 fixed to the top of the movable plate 10 and a belt drive assembly. The movable tube 11 is connected to the output shaft of the motor 15 via the belt drive assembly. The belt drive assembly includes two pulleys 16 and a belt. The two pulleys 16 are respectively fixed to the output shaft of the motor 15 and the movable tube 11. The pulleys 16 are connected by belt drive. The pulleys 16 and the belt preferably adopt a synchronous pulley and synchronous belt structure. The control assembly includes a fixed plate 17 fixed to the top of the separation cylinder 1 and a cylinder 18 fixed to the top of the fixed plate 17. The drive shaft of the cylinder 18 is fixedly connected to the movable plate 10, and a U-shaped connecting frame is fixed between the drive shaft of the cylinder 18 and the top of the movable plate 10.
[0037] During cleaning, the movable tube 11 is first moved downward by the drive shaft of cylinder 18, bringing the nozzle 12 closer to the separation screen plate 2. Motor 15 drives the movable tube 11 to rotate via pulley 16 and belt, causing the nozzle 12 to evenly spray and wash the separation screen plate 2. After cleaning, the drive shaft of cylinder 18 drives the movable plate 10 upward to reset, positioning the nozzle 12 above the outlet pipe 4 to prevent the wastewater from contaminating the nozzle 12 and movable tube 11.
[0038] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:
[0039] When the water to be treated is filtered to separate impurities, it is transported into the inlet header 7. The opening of valves two and three on the inlet pipe 5 and the outlet pipe 4, and the closing of valve one on the drain pipe 3 are controlled. The water to be treated overflows into the separation cylinder 1 through the inlet pipe 5. After being filtered and separated from impurities by the separation screen 2, the filtered water is discharged into the outlet header 8 through the outlet pipe 4 for collection.
[0040] When the separation screen 2, which is used for water treatment, approaches saturation and becomes clogged, valves two and three on the inlet pipe 5 and outlet pipe 4 are closed, and valve one on the drain pipe 3 is opened. Simultaneously, the inlet pipe 5 and outlet pipe 4 on the other separation cylinder 1 are open, and valve one on the drain pipe 3 is closed. The water to be treated is then transported to the clean separation cylinder 1, where the separation screen 2 remains, for continuous water treatment.
[0041] When cleaning the clogged separator screen 2, the drive shaft of cylinder 18 drives the movable tube 11 downward, bringing the nozzle 12 closer to the separator screen 2. Valve four on the water inlet pipe 21 of the separator cylinder 1 to be cleaned is opened, and external clean water is delivered to the water supply pipe 13 through the water inlet header 9, water inlet pipe 21, and hose 20, providing a cleaning water source for the nozzle 12. Motor 15 drives the movable tube 11 to rotate via pulley 16 and belt, causing the nozzle 12 to evenly spray and clean the separator screen 2. This allows for automatic cleaning of the separator screen 2, facilitating subsequent water treatment after the separator cylinder 1 has been cleaned and the water treatment process has been switched back to normal.
[0042] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
