Description

Technical Field

[0001] This utility model relates to the field of wastewater sedimentation technology, and in particular to a wastewater sedimentation and purification device. Background Technology

[0002] Wastewater sedimentation is a fundamental and crucial physical treatment step in water treatment. Its core principle is to utilize gravity to allow suspended solids in wastewater to settle naturally, thus separating the sludge from the water. The relatively clear supernatant is collected and sent to subsequent treatment units. It effectively removes most settleable solids, significantly reducing wastewater turbidity and organic load. This not only lightens the burden on subsequent biological or chemical treatment processes but also lays a vital foundation for achieving compliant effluent discharge. Therefore, sedimentation is an indispensable first or pre-treatment step in most wastewater treatment plants.

[0003] A search revealed Chinese patent publication number CN222935227U, which discloses a wastewater sedimentation and purification device. The device includes a sedimentation tank frame, an extension frame connected to one side of the outer wall of the sedimentation tank frame, a conveying frame connected to the side of the extension frame away from the sedimentation tank frame, and a sedimentation cleaning structure disposed within the sedimentation tank frame, the extension frame, and the conveying frame. The sedimentation cleaning structure includes multiple rotating threaded assemblies, multiple main gears, a cleaning groove frame, a fixed baffle, and a clamping frame. The outer wall of the cleaning groove frame is fixedly embedded within the sedimentation tank frame and the extension frame, the outer wall of the clamping frame is fixedly embedded between the extension frame and the cleaning groove frame, and the outer wall of the fixed baffle is fixedly embedded within the cleaning groove frame.

A rotating gear ring 10 is rotatably connected to the top of the tank 1. A rotating drive assembly is driven to one side of the rotating gear ring 10. A sludge collection tank 14 is fixedly connected to the bottom of the rotating gear ring 10. A sludge collection shovel plate 15 is fixedly connected to one side of the sludge collection tank 14. The sludge collection tank 14 and the sludge collection shovel plate 15 are rotatably connected to the outside of the air inlet pipe 3. Multiple filter holes 21 are opened on one side of the sludge collection shovel plate 15 and the sludge collection tank 14. The rotating drive assembly includes a drive motor 16 and a drive gear 17. The drive motor 16 is fixedly connected to one side of the tank 1, and the drive gear 17 is fixedly connected to the power output end of the drive motor 16. The rotating gear ring 10 and the drive gear 17 mesh with each other. When wastewater enters tank 1 for sedimentation, some dirt will float to the surface. At this time, the drive motor 16 is started, which drives the rotating gear ring 10 on one side to rotate through the drive gear 17 above, which in turn drives the sludge collection shovel 15 to rotate, thus scooping up the suspended dirt floating on the water surface and purifying the water surface. The dirt scooped up by the sludge collection shovel 15 accumulates on top. Recently, excessive dirt will enter the sludge collection tank 14 for centralized collection and recycling.

[0023] In this embodiment, a water inlet pipe 4 is fixedly connected to one side of the tank body 1 and the air inlet pipe 3, the water outlet of the water inlet pipe 4 is located inside the air inlet pipe 3, and a reflector plate 9 is fixedly connected to the bottom of the air inlet pipe 3. The air inlet pipe 3 can spray air downwards from the external air pump to flush the sewage containing sediment that is flushed in from the water inlet pipe 4 into the tank 1. The heavier sediment will sink after entering the tank 1, while the lighter sediment mixed with the gas will float up and be retrieved by the sludge collection shovel 15. A water suction pipe 5 and a sewage discharge pipe 6 are fixedly connected to one side of the tank body 1; a sewage collection pipe 2 is fixedly connected to the bottom of the tank body 1, and a sewage discharge suction port 8 is fixedly connected to the lower end of the sewage discharge pipe 6, with the sewage discharge suction port 8 located inside the sewage collection pipe 2. Then, the pumping pipe 5, located at the top, can draw out the relatively clean supernatant, while the heavier dirt falls to the bottom and eventually accumulates in and above the collection pipe 2. At this point, the external pump connected to the drain pipe 6 can collect and discharge the dirt for cleaning.

[0024] In this embodiment: when sewage enters tank 1 for sedimentation, some dirt will float on the water surface. At this time, drive motor 16 is started, and drive gear 17 above to drive the rotating gear ring 10 on one side to rotate, which in turn drives the sludge collection shovel 15 to rotate, which will scoop up the suspended dirt floating on the water surface, thus purifying the water surface. The dirt scooped up by the sludge collection shovel 15 will accumulate on the top. Recently, the dirt that has accumulated too much will enter the sludge collection tank 14 for centralized collection and waiting for recycling. The air inlet pipe 3 can spray air downwards from the external air pump to flush the sewage containing sediment that is flushed in from the water inlet pipe 4 into the tank 1. The heavier sediment will sink after entering the tank 1, while the lighter sediment mixed with the gas will float up and be retrieved by the sludge collection shovel 15. Then, the pumping pipe 5, located at the top, can draw out the relatively clean supernatant, while the heavier dirt falls to the bottom and eventually accumulates in and above the collection pipe 2. At this point, the external pump connected to the drain pipe 6 can collect and discharge the dirt for cleaning.
