Environment-friendly water sedimentation tank

Abstract

The invention belongs to the field of sedimentation tanks, and discloses an environment-friendly water sedimentation tank which comprises a sedimentation tank body, a sewage discharge plate and a transmission structure, a sewage discharge port is formed in the right end of the lower portion of the sedimentation tank body, a sewage discharge pipe is connected to the sewage discharge port, a control valve is arranged on the sewage discharge pipe, a boss surface is arranged on the right wall in the sedimentation tank body, and a rotating shaft is arranged on the boss surface and is rotatably connected with the lower end part of hte sewage discharge plate. At least one supporting block is arranged on the left inner wall of the sedimentation tank body, one end of the transmission structure is connected with the upper portion of the sewage discharge plate, the other end of the transmission structure is connected with the control valve, a boss is arranged on the upper portion of the right wall in the sedimentation tank body, and when the control valve is closed, the right end of the sewage discharge plate makes contact with the boss. The sewage discharge plate is arranged in parallel to form a gap, so that water at the upper part of the sewage discharge plate flows into the bottom of the sedimentation tank body through the gaps, bottom water flow drives impurities to be discharged at a high speed, the impurities at the bottom of the sedimentation tank body can be basically discharged, operators are facilitated, time and labor are saved, and water quality is protected.

Description

technical field [0001] The invention belongs to the field of sedimentation tanks, in particular to a water-friendly sedimentation tank. Background technique [0002] Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water and is an equipment for purifying water quality. Use the natural precipitation of water or the effect of coagulation and sedimentation to remove suspended solids in water. [0003] A lot of debris will be deposited at the bottom of the existing sedimentation tank, and the impurities are discharged through the sewage pipe at the bottom, and the impurities are driven into the sewage pipe by the water flow, but only through the sewage pipe, only the impurities near the sewage outlet can be discharged. Water generally flows from top to bottom to the sewage outlet, resulting in a slow water flow around the impurities at the bottom of the sedimentation tank far away from the sewage outlet, which cannot drive the impurities, ...

Problems solved by technology

[0003] A lot of debris will be deposited at the bottom of the existing sedimentation tank, and the impurities are discharged through the sewage pipe at the bottom, and the impurities are driven into the sewage pipe by the water flow, but only through the sewage pipe, only the impurities near the sewage outlet can be discharged. Water generally flows from top to bottom to the sewage outlet, resulting in a slow water flow around the impurities at the bottom of the sedimentation tank far away from the sewage outlet, which cannot drive the impurities, resulting in the inability to discharge the impurities, incomplete sewage discharge, and troublesome manual salvage of the remaining impurities , and more impurities left over for a long time will affect the filtered water quality
