Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment pools, in particular to an overflow pool and a sediment removal system for sedimentation tanks. Background Technique

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended solids in water, a device for purifying water quality. It utilizes the natural sedimentation or coagulation sedimentation of water to remove suspended solids in water. Sedimentation tanks are divided into horizontal sedimentation tanks and vertical sedimentation tanks according to the water flow direction. The sedimentation effect depends on the water flow velocity in the sedimentation tank and the residence time of water in the tank. In order to improve the sedimentation effect and reduce the land area, honeycomb inclined tube countercurrent sedimentation tanks, accelerated clarifiers, pulse clarifiers, etc. are mostly used. Sedimentation tanks are widely used in wastewater treatment.

[0003] The working principle characteristics of the sedimentation tank lead to the accumulation of sediment at the bottom of the sedimentation tank. Regularly cleaning the sediment in the sedimentation tank is one of the important tasks in sewage treatment. Manual and mechanical cleaning are the main current cleaning methods. Manual cleaning is not only dangerous but also has a high labor intensity, and it requires the sedimentation tank to drain water and stop working for cleaning. Mechanical cleaning has a high construction cost, is not cleaned thoroughly, and is prone to failure and maintenance. Therefore, a new overflow pool and sediment removal system for sedimentation tanks are proposed to reduce the equipment cost investment and improve the sediment removal effect.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] The sediment removal system for the overflow pool includes an overflow pool, a sludge separator and a control terminal. The bottom of the overflow pool is a corrugated bottom. A push flow pipeline is arranged in the corrugated bottom. The push flow pipeline is communicated with the push flow medium pipeline through a branch pipe and a summary pipe. A sedimentation tank is arranged on one side of the push flow direction of the overflow pool. The sludge separator is communicated with the sedimentation tank through a sewage suction system.

[0007] As a further scheme of the utility model: The corrugated bottom is built by stacking wedge-shaped bricks, the top is an inclined cut surface, and the side is a vertical cut surface. The sediment is pushed over one row of wedge-shaped bricks to the sedimentation tank of the overflow pool through the medium.

[0008] As a further scheme of the utility model: The push flow pipeline is provided with equally spaced jet pipes. The jet pipes blow out from the vertical cut surface of the corrugated bottom at an angle with the top being an inclined cut surface, and push the pool water to flow and push the sediment in the same direction.

[0009] As a further solution of the utility model: a control valve is arranged on the branch pipe, a medium pump is arranged between the collecting pipe and the flow-pushing medium pipeline, and both the control valve and the medium pump are controlled through the control end.

[0010] As a further solution of the utility model: the flow-pushing medium pipeline is provided with two input ends through a three-way valve, which are respectively a fluid medium input end and a gas medium input end, and the fluid medium input end is communicated to the sewage liquid level in the overflow pool.

[0011] As a further solution of the utility model: the sewage suction system comprises a sewage suction pipe, a sewage suction pump and a sewage delivery pipeline. A plurality of sewage suction pipes are arranged on one side of the sedimentation tank. The sewage suction pipe uses the sewage suction pump to lift the sediment and sewage together to the sewage delivery pipeline, and is sent to the sludge separator through the sewage delivery pipeline.

[0012] As a further solution of the utility model: the liquid-phase output end of the sludge separator sends the sewage back to the overflow pool through the reflux pipeline.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] For this overflow pool sediment removal system, the bottom of the overflow pool is designed with a corrugated bottom. Under the flow-pushing action of the flow-pushing pipeline, the sediment is conveyed to one side, causing the sediment to reach the sedimentation tank for sedimentation.

[0017] Please refer to Figure 1, in the embodiment of the present utility model, the sediment removal system of the overflow pool includes an overflow pool 1, a sludge separator 2 and a control terminal 10. The bottom of the overflow pool 1 is a corrugated bottom 3. A push-flow pipeline 4 is arranged in the corrugated bottom 3. The push-flow pipeline 4 is communicated with a push-flow medium pipeline 8 through a branch pipe 5 and a collecting pipe 6. A sedimentation tank 11 is arranged on one side of the overflow pool 1 in the push-flow direction. The sludge separator 2 is communicated with the sedimentation tank 11 through a sewage suction system. Through the design of the corrugated bottom 3, the reverse flow of sediment is reduced. The push-flow pipeline 4 pushes out the medium, drives the bottom sewage to flow, prevents sediment deposition, and the sediment flows to the sedimentation tank 11 along the push-flow direction and floats and is measured in the sedimentation tank 11. The slope of the sedimentation tank 11 is large, and the sediment settles at the bottom along the slope of the sedimentation tank 11, so as to avoid the sediment settling in other areas, and keep other areas of the pool bottom clean. It should be noted that the bottom carrier of the overflow pool 1 is not limited to a plane, and a slope design is more conducive to the sedimentation of sediment.

[0018] In a preferred embodiment, the corrugated bottom 3 is built by stacking wedge-shaped bricks. The top is an inclined cut surface, and the side is a vertical cut surface. The sediment is pushed by the medium over a row of wedge-shaped bricks to the sedimentation tank 11 of the overflow pool 1. The inclined cut surface design at the top has two major advantages. Advantage one, it is conducive to the sediment approaching the jet pipe, and when the jet pipe ejects, it can better make the water flow carry away the sediment. Advantage two, it creates a slope and forms a vertical cut surface to prevent the sediment from flowing back.

[0019] In a preferred embodiment, the push-flow pipeline 4 is provided with jet pipes arranged at equal distances. The jet pipes blow out from the vertical cut surface of the corrugated bottom 3 at an angle with the top being an inclined cut surface, pushing the pool water to flow and pushing the sediment in the same direction. The radiation range of the jet pipes of the push-flow pipeline 4 should cover the entire pool bottom to avoid the phenomenon of sediment accumulation in dead corners.

[0020] In a preferred embodiment, a control valve 9 is arranged on the branch pipe 5, and a medium pump 7 is arranged between the collecting pipe 6 and the push-flow medium pipeline 8. Both the control valve 9 and the medium pump 7 are controlled by the control terminal 10. The control terminal 10 controls the control valve 9 to operate in multiple modes, and rotates different sedimentation modes according to different sedimentation conditions. The control valve 9 can operate in the push-flow sequence in turn, and the control valve 9 can also clean the sediment intermittently or continuously at the same time.

[0021] In a preferred embodiment, the push-flow medium pipeline 8 is provided with two input ends through a three-way valve, namely a fluid medium input end and a gas medium input end. The fluid medium input end is communicated to the sewage liquid level in the overflow pool 1. The push-flow of the sewage medium can reduce the generation of bubbles and reduce the phenomenon of floc floating. The push-flow of the gas medium can increase the oxygenation amount and speed up the reaction.

[0022] In a preferred embodiment, the sewage suction system comprises a sewage suction pipe 12, a sewage suction pump 13 and a sewage delivery pipeline 14. A plurality of sewage suction pipes 12 are arranged on one side of the sedimentation tank 11. The sewage suction pipes 12 lift the sediment and sewage together to the sewage delivery pipeline 14 through the sewage suction pump 13, and are sent into the sludge separator 2 through the sewage delivery pipeline 14. The sewage suction pipes 12 are arranged in rows, and the sewage suction range covers the entire sedimentation tank 11. The sediment in the sedimentation tank 11 is sucked out through the sewage suction pipes 12 and enters the sludge separator 2. The liquid-phase output end of the sludge separator 2 sends the sewage back to the overflow pool 1 through the reflux pipeline 15. The sediment is compressed and separated, and the liquid phase flows back into the overflow pool 1 for continuous sedimentation treatment.

[0023] It should be noted that the above embodiments all belong to the same inventive concept of the utility model. The descriptions of the embodiments have their own emphases. For the parts not described in detail in individual embodiments, reference can be made to the descriptions in other embodiments.

It should be pointed out that for those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
