[0002] Sedimentation tanks are equipment that uses the natural sedimentation or coagulation sedimentation of water to remove suspended solids in water and purify water quality. Sedimentation tanks are widely used in sewage treatment. There are many types of sedimentation tanks, which can be divided into three types according to the direction of water flow in the tank: horizontal flow, vertical flow and radial flow. The sedimentation effect depends on the flow rate of water in the sedimentation tank and the residence time of water in the tank.

[0021] From the above description, it can be seen that the beneficial effects of the utility model are: by setting the inner tank body 2 and the outer tank body 1, the space utilization rate can be improved, the sludge can be effectively prevented from accumulating on the wall of the outer tank body 1, the cleaning cost can be reduced, and the sewage treatment sedimentation effect can be improved; the water inlet pipe 3 is directly connected to the inner tank body 2, which can play a good role in limiting the flow and inhibiting, and prevent the sedimentation effect in the sedimentation tank from being affected by excessive fluctuations when the sewage enters. The process is simple, the cost is low, the operation and maintenance are convenient, no electricity resources are required, the treatment effect is stable, and no secondary pollution will be caused.

[0022] Furthermore, a bottom bracket 8 is included, and a bottom bracket 8 is connected between the bottom of the inner tank body 2 and the bottom of the outer tank body 1 .

[0023] It can be seen from the above description that the inner tank body 2 is supported by the bottom bracket 8 , and at the same time, the bottom bracket 8 allows space between the bottom of the inner tank body 2 and the bottom of the outer tank body 1 so that sludge can settle and accumulate and be discharged by the sludge discharge pipe 4 .

[0024] Furthermore, it also includes a top bracket 7, and a plurality of top brackets 7 are connected between the top of the inner tank body 2 and the wall of the outer tank body 1.

[0025] It can be seen from the above description that the position of the inner tank body 2 in the outer tank body 1 is fixed by the top bracket 7 to improve the stability of the inner tank body 2.

[0026] Furthermore, the outer tank body 1 and the inner tank body 2 are in a square cone shape; the top cross-sections of the outer tank body 1 and the inner tank body 2 are both smaller than their respective bottom cross-sections.

[0027] From the above description, it can be seen that the square cone design is conducive to guiding the sedimentation of sludge.

[0029] From the above description, it can be seen that the horizontal pipe can reduce the impact force when sewage is discharged; and the setting of the vertical pipe can directly introduce the sewage into the inner tank body 2, so that the sludge will not accumulate and adhere to the wall of the outer tank body 1 when it settles; the setting of openings at both ends of the vertical pipe can reduce the pressure inside the pipe and prevent the pipe from being blocked during the water intake process.

[0030] Furthermore, the opening of one end of the vertical pipe extending toward the inner tank body 2 is trumpet-shaped.

[0031] It can be seen from the above description that the setting of the trumpet-shaped opening can reduce the fluctuation when sewage enters, thereby improving the sedimentation effect in the sedimentation tank.

[0034] Furthermore, the pool wall around the top of the outer pool body 1 is provided with a plurality of tooth-shaped structures, and the tooth grooves of the tooth-shaped structures form an overflow port 9.

[0035] It can be seen from the above description that the water on the upper side of the outer tank body 1 after settling can flow out from the overflow port 9 after continuous water inflow; the tooth grooves of the tooth-shaped structure can guide the water flow to flow out to a designated position, which is convenient for subsequent processing.

[0036] Furthermore, the inner tank body 2 and the outer tank body 1 are made of reinforced concrete, metal, plastic or composite material.
