Abstract
Description
Technical Field
[0001] This utility model relates to the field of inclined tube sedimentation tank technology, specifically an inclined tube sedimentation tank for high-efficiency sludge sedimentation. Background Technology
[0002] An inclined tube sedimentation tank is a sedimentation tank with inclined tubes within the sedimentation zone. There are two assembly methods: inclined tube and branch pipe. In a horizontal flow sedimentation tank, the sedimentation zone is divided into a series of shallow sedimentation layers using inclined parallel tubes or parallel pipes (sometimes honeycomb packing). The treated and settled sludge move and separate within these shallow sedimentation layers. Currently, the commonly used inclined tube sedimentation tank structures on the market typically have walls made of concrete or steel. Utility Model Content
[0003] The purpose of this invention is to provide an efficient inclined tube sedimentation tank for sludge sedimentation, in order to solve the problem of poor sludge discharge at the bottom of the commonly used inclined tube sedimentation tanks mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an inclined tube sedimentation tank for efficient sludge sedimentation, comprising a first sedimentation tank and a second sedimentation tank located on one side of the first sedimentation tank. An inclined tube support frame is installed at the top of the interior of the second sedimentation tank, and an inclined tube is fixed to the surface of the inclined tube support frame. A clear water trough is provided on one side of the top of the second sedimentation tank, and a deep well trough is provided on one side of the clear water trough. A sludge discharge trough is provided on one side of the first sedimentation tank and the second sedimentation tank, and one end of the sludge discharge trough is connected to a sludge discharge pipe. An inclined bucket is provided at the bottom of both the first sedimentation tank and the second sedimentation tank, and the inclined bucket is connected to the first sedimentation tank and the second sedimentation tank. An auger is connected to the bottom of the inclined bucket, which facilitates sludge discharge.
[0005] Preferably, the first sedimentation tank and the second sedimentation tank are provided with perforated sludge pipes at equal intervals, one end of which extends into the interior of the sludge discharge trough.
[0006] Preferably, the top ends of the first sedimentation tank and the second sedimentation tank are connected by perforated water collection pipes with equal spacing.
[0007] Preferably, a water inlet pipe is installed at the bottom of the water tank, which facilitates drainage.
[0008] Preferably, a deep well water inlet pipe is connected to the center of the bottom of the deep well trench, and connecting pipes are connected to both sides of the bottom of the deep well trench and the deep well water inlet pipe.
[0009] Preferably, a branch pipe is connected to the surface of the clear water tank and to one side of the clear water pool inlet pipe, and the branch pipe is interconnected with the deep well tank.
[0010] Compared with existing technologies, the beneficial effects of this invention are as follows: This high-efficiency sludge sedimentation tank uses inclined tubes on the surface of the inclined tube support frame to stratify the wastewater, allowing the sludge to enter the bottom of the first and second sedimentation tanks. The sludge is then collected at the bottom via inclined buckets and transported outside the tanks for treatment via an auger. The upper layer of water is discharged into the clear water tank through perforated collection pipes, and then connected to the clear water tank's inlet pipe. It also enters the deep well tank through branch pipes, and is finally discharged through the deep well inlet pipe and connecting pipe. The invention improves the convenience of sludge removal by modifying the bottom of the first and second sedimentation tanks with inclined buckets and an auger structure. Attached Figure Description

[0018] The present invention provides a structure for an efficient inclined tube sedimentation tank for sludge sedimentation, as shown in the figure below. Figures 1 to 4 As shown, the system includes a first sedimentation tank 1 and a second sedimentation tank 2 located on one side of the first sedimentation tank 1. The tops of the first sedimentation tank 1 and the second sedimentation tank 2 are connected by perforated water collection pipes 11 with equal spacing. The bottoms of the first sedimentation tank 1 and the second sedimentation tank 2 are both equipped with inclined buckets 12, which are connected to the first sedimentation tank 1 and the second sedimentation tank 2. The bottom of the inclined bucket 12 is connected to an auger 13, which facilitates sludge discharge. The top of the second sedimentation tank 2 is equipped with an inclined tube support frame 3, and an inclined tube 4 is fixed on the surface of the inclined tube support frame 3. A clear water trough 5 is provided on one side of the top of the second sedimentation tank 2, and a deep well trough 6 is provided on one side of the clear water trough 5. A sewage discharge trough 9 is provided on one side of the first sedimentation tank 1 and the second sedimentation tank 2, and one end of the sewage discharge trough 9 is connected to a sewage discharge pipe 91.
[0019] During implementation, the wastewater is stratified by the inclined tubes 4 on the surface of the inclined tube support frame 3, so that the sludge enters the bottom of the first sedimentation tank 1 and the second sedimentation tank 2.
[0020] Furthermore, such as Figures 3 to 5 As shown, the first sedimentation tank 1 and the second sedimentation tank 2 are equipped with perforated sludge pipes 10 at equal intervals. One end of the perforated sludge pipe 10 extends into the interior of the sewage trough 9. The center of the bottom of the deep well trough 6 is connected to the deep well water inlet pipe 8. The bottom of the deep well trough 6 and both sides of the deep well water inlet pipe 8 are connected to the connecting pipes 81. The bottom of the clear water trough 5 is equipped with a clear water tank inlet pipe 7, which facilitates drainage. The surface of the clear water trough 5 and one side of the clear water tank inlet pipe 7 are connected to the branch pipe 71, which is connected to the deep well trough 6.
[0021] During implementation, the sludge is discharged into the interior of the sewage tank 9 through the perforated sludge pipe 10, and finally drained through the sewage pipe 91; while the water in the upper layer is discharged into the interior of the sludge and clear water tank 5 through the perforated water collection pipe 11, and then enters the interior of the deep well tank 6 through the clear water tank water inlet pipe 7, and finally discharged through the deep well water inlet pipe 8 and the connecting pipe 81.
[0022] Working principle: In use, the sewage is first stratified by the inclined tubes 4 on the surface of the inclined tube support frame 3, so that the sludge enters the bottom of the first sedimentation tank 1 and the second sedimentation tank 2, and then is discharged into the interior of the sewage discharge trough 9 through the perforated sludge pipe 10, and finally drained through the sewage discharge pipe 91; while the water in the upper layer is discharged into the interior of the sludge and clear water trough 5 through the perforated water collection pipe 11, and is connected to the clear water tank water inlet pipe 7, and also enters the interior of the deep well trough 6 through the branch pipe 71, and is finally discharged through the deep well water inlet pipe 8 and the connecting pipe 81.
[0023] The commonly used inclined tube sedimentation tank structure on the market can be made of concrete or steel. In this utility model, the bottom of the first sedimentation tank 1 and the second sedimentation tank 2 are changed to an inclined bucket with an added auger structure for sludge removal, which improves the convenience of sludge removal.
