[0027] In the embodiment, the two ends of the movable partition 40 are rotatably connected to the middle portions of the two side walls (front and rear side walls) of the sediment tank 10. Specifically, the movable partition 40 comprises rotating shafts 41 and plate bodies 42 sleeved on the rotating shafts 41. The two ends of the rotating shafts 41 are rotatably connected to the middle portions of the front and rear side walls of the sediment tank 10. There are four movable partitions 40. The rotating shafts 41 of the four movable partitions 40 are parallel and spaced apart. The center lines of the rotating shafts 41 of the four movable partitions 40 are located on the same horizontal plane. When the movable partitions 40 are in the first working position, the plate bodies 41 of all the movable partitions 40 abut against each other to separate the water bodies above and below the movable partitions 40.

[0028] Further, the water treatment system of the water plant further comprises a driving assembly 50 for driving the movable partitions 40 to rotate. The driving assembly 50 is connected to the protruding portions 411 of the rotating shafts 41 penetrating through the side walls of the sediment tank 10. Specifically, the driving assembly 50 comprises gears 51 sleeved on the protruding portions 411, a rack 52 in meshing engagement with all the gears 51, and a hydraulic cylinder 53. The rack 52 is linearly movably arranged on the side wall of the sediment tank 10. When the rack 52 moves linearly, all the movable partitions 40 can be driven by the gears 51 to rotate synchronously to the first working position and the second working position. The hydraulic cylinder 53 is used to drive the rack to move linearly. The cylinder body 531 of the hydraulic cylinder 53 is arranged on the side wall of the sediment tank 10. The end of the hydraulic rod 532 of the hydraulic cylinder 53 is connected to the end of the rack 52.

[0029] In the embodiment, the water replenishing assembly 20 comprises water supply pipes 21, a connecting pipe 22, and a guide pipe 23. There are two water supply pipes 21. The two water supply pipes 21 are arranged at the upper ends of the two side walls (front and rear side walls) of the sediment tank 10. Long strip-shaped water supply ports 211 are formed on the surfaces of the two water supply pipes 21 facing each other. The connecting pipe 22 is in the shape of U. The two ends of the connecting pipe 22 are in communication with the ends of the two water supply pipes 21. The middle portion of the connecting pipe 22 is in communication with the guide pipe 23. The guide pipe 23 is located above the side wall of the sediment tank 10.

[0030] Further, the water supply assembly 20 further comprises a water permeable plate 24 arranged at the upper end of the sediment tank 10. The water permeable plate 24 extends along the horizontal plane. The upper surface of the water permeable plate 24 is provided with flow slowing plates 241 parallel to the water supply pipes 21. The upper end surface of the flow slowing plates 241 is lower than the water supply ports 211. There are multiple flow slowing plates 241 parallel and spaced apart. The flow slowing plates 241 are S-shaped plates. Each flow slowing plate 241 is composed of multiple flow slowing plate segments 242. Adjacent flow slowing plate segments 242 are spaced apart.

All the through holes 243 are arranged in an array. There is at least one column of through holes 243 between adjacent flow slowing plates 241.

[0031] When the conduit 23 supplies water to the sediment tank 10 through the connecting pipe 22 and the water supply pipe 21, the raw water flowing out of the water supply port 211 is blocked by the slow flow plate 241 and is dispersed to all the through holes 243 through the gaps between the adjacent slow flow plates 241, and then flows into the sediment tank 10 through the through holes 243. The dispersed water flow has a reduced flow rate and impact force, and thus does not cause impact on the water body in the sediment tank 10 and does not affect the sedimentation effect.

[0032] To improve the dispersion efficiency of the water flow, further, the water-permeable holes 244 are formed in the slow flow plate segments 242.

[0033] The operation process of the sedimentation device for the water purification system of the water plant is described below.

[0034] When it is necessary to sediment and purify the raw water, the raw water to be sedimented is first poured into the sediment tank through the conduit, the connecting pipe and the water supply pipe, so that the raw water can be sedimented in the sediment tank. Before pouring, the hydraulic cylinder is actuated to move the rack and rotate the gear, so that all the movable partitions are synchronously rotated to the second working position to expand the pouring space and enable the sediment tank to be filled. At this time, the sludge in the raw water continuously sinks and accumulates on the sludge collecting plate. When it is necessary to clean the sludge accumulated on the sludge collecting plate, the hydraulic cylinder is actuated to move the rack and reverse the gear, so that all the movable partitions are synchronously rotated to the first working position to isolate the water bodies above and below the movable partitions. At this time, the sludge collecting plate is pulled out from the side, and the sludge accumulated on the sludge collecting plate can be cleaned. During the cleaning, the water body above the movable partitions is not disturbed, and the sludge sedimented on the sludge collecting plate is not floated again into the water body.

[0035] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
