[0027] As Figure 1-2 shown, a sedimentation tank for soil and water conservation includes a box body 1 and a horizontal plate 2. The horizontal plate 2 is fixedly connected to the inner wall of the box body 1. The inlet pipe 3 vertically penetrates and is fixedly connected to the horizontal plate 2. It also includes a filtering and discharging assembly and a re - filtering and pumping assembly. Both the filtering and discharging assembly and the re - filtering and pumping assembly are arranged inside the box body 1, and the re - filtering, discharging and pumping assembly is arranged below the filtering and discharging assembly.

[0028] The filtering and discharging assembly is used to filter and treat sewage and clean sand and stone impurities, and the re - filtering and pumping assembly is used to re - filter and discharge the filtered sewage.

[0029] As Figure 1-5 shown, in order to reduce the blockage of the filtering element and the frequency of manual cleaning, the filtering and discharging assembly includes an upper filter plate 4, an electric push rod 5, a cleaning plate 6, brush bristles 7, a servo motor 8 and a propeller blade 9. The upper filter plate 4 is fixedly connected between the inner walls of the box body 1. The electric push rod 5 obliquely penetrates and is fixedly connected to one side of the box body 1. The cleaning plate 6 is fixedly connected to the free end of the electric push rod 5. The brush bristles 7 are evenly distributed at the bottom of the cleaning plate 6. The servo motor 8 is fixedly installed on the outer side wall of the box body 1. The propeller blade 9 is fixedly connected to the output end of the servo motor 8; the upper filter plate 4 is inclined, and one side thereof is arc - shaped. The brush bristles 7 are made of nylon wire and are in contact with the top of the upper filter plate 4.

[0030] As Figure 1-5As shown in the figure, in order to improve the filtering effect on sewage, the re-filtering pumping assembly includes a lower filter plate 10, a float 11 and a water pump 12. The lower filter plate 10 is arranged inside the box body 1 and below the upper filter plate 4. The float 11 is fixedly connected to the bottom of the lower filter plate 10 and is symmetrically distributed. The water pump 12 is fixedly installed on the outer wall of the box body 1, and its output end is arranged inside the box body 1.

[0031] In order to accelerate the filtering efficiency of the upper filter plate 4 and the rolling speed of impurities, symmetrically distributed waterproof boxes 13 are fixedly connected to the bottom of the upper filter plate 4, and vibration motors 14 are fixedly installed inside the waterproof boxes 13.

[0032] In order to increase the stability of the movement of the connecting plate, a reinforcing frame 15 is fixedly connected to the outer wall of the electric push rod 5 and is fixedly connected to the outer wall of the box body 1. A guide rod 16 is fixedly connected to the outer wall of the cleaning plate 6, and one end of the guide rod penetrates through one side of the box body 1 and is slidably connected thereto.

[0033] Among them, a cleaning door 17 is provided on the box body 1, and a discharge pipe 18 is provided on one side of the box body 1. One end of the discharge pipe is threadedly connected with a plugging cover 19. The discharge pipe 18 communicates with the inside of the box body 1. Both ends of the bottom of the lower filter plate 10 are convexly arranged.

[0034] During specific use, sewage is added into the box body 1 through the water inlet pipe 3. The vibration motor 14 is started to accelerate the filtering speed of the upper filter plate 4 and the rolling speed of sand and gravel. The electric push rod 5 is controlled to extend, and the movement of the cleaning plate 6 enables the brush hairs 7 to clean the upper filter plate 4 to prevent impurities from blocking it. The sand and gravel are concentrated at the arc-shaped part on the top of the upper filter plate 4. The servo motor 8 is started, and the uniform rotation of the propeller blades 9 can uniformly transport the sand and gravel impurities to the outside of the box body 1. Through the above operations, the filtering efficiency of sewage is improved and the number of manual cleanings is reduced.

[0035] The sewage after primary filtration is subjected to secondary filtration under the action of the lower filter plate 10. Subsequently, the lower filter plate 10 floats under the action of the float 11, which ensures that the water at the bottom of the lower filter plate 10 has all been subjected to secondary filtration. The water pump 12 is started, and the water after secondary filtration can be pumped out.
