Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation devices, in particular to a circulating and efficient sedimentation device. Background Art

[0002] In the prior art, a patent with the application number CN202020563571.7 discloses a circulating and efficient sedimentation device, which includes a first sedimentation tank and a second sedimentation tank. One side of each of the first sedimentation tank and the second sedimentation tank is communicated with a sewage discharge pipe. The first sedimentation tank and the second sedimentation tank are communicated through a first water outlet pipe. The top of the first sedimentation tank is communicated with a first water inlet pipe. One side of the second sedimentation tank is communicated with a second water outlet pipe. The top of the second sedimentation tank is communicated with a connecting pipe, and the other end of the connecting pipe is communicated with the second water outlet pipe. A water pump is arranged on the connecting pipe. In the utility model, through the first filter screen arranged in the first sedimentation tank and the second filter screen arranged in the second sedimentation tank, the sewage is sedimented and filtered twice to improve the sedimentation effect. The water that does not meet the sewage discharge standard is pumped into the second sedimentation tank through the connecting pipe by the water pump for re-sedimentation and filtration, further improving the sedimentation effect and ensuring that the discharged water will not pollute the river again.

[0003] However, in this technical solution, the sewage first enters the first sedimentation tank for sedimentation, so the sealing performance of the bottom of the first sedimentation tank is required to be relatively high. The two-way cylinder arranged at the bottom will affect the sealing performance of the first sedimentation tank.
