Sedimentation tank for industrial sewage treatment

Abstract

The invention relates to a sedimentation tank for industrial sewage treatment, which comprises a main body, a pressure relief mechanism and a buffer mechanism, wherein the pressure relief mechanism is arranged on the main body, the buffer mechanism is arranged in the pressure relief mechanism, the pressure relief mechanism comprises a water inlet pipe, a connecting pipe, a box body and a blocking assembly, the buffer mechanism is arranged on a sleeve, the buffer mechanism comprises a plurality of buffer assemblies, the buffer assembly comprises a buffer unit and a plugging unit, and a limiting unit is arranged on the fixing rod. According to the sedimentation tank for industrial sewage treatment, pressure relief is conducted on water through the pressure relief mechanism, and impact force of the water is buffered through the buffer mechanism. Compared with an existing sedimentation tank, the device relieves and buffers the impact force of the water, water slowly flows into the main body, and impurities at the bottom of the main body are prevented from being impacted and turning over up and down, so that the better precipitation effect is achieved. Meanwhile, multiple pressure relief buffering is conducted through the pressure relief mechanism and the buffer mechanism, so that the better pressure relief buffering effect is achieved, and the practicability is improved.

Description

technical field [0001] The invention relates to a sedimentation tank used for industrial sewage treatment. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Various fields have increasingly entered the daily life of ordinary people. Sewage treatment methods include air flotation, centrifugal, sedimentation, etc. [0003] When the existing sedimentation sewage treatment device is in use, when the sewage is injected into the sedimentation tank, the sewage will generate a large impact force, and the impact force will rush into the pool, which will cause the water in the sedimentation tank to slosh, thus making the bottom of the sedimentation tank The precipitated impurities ru...

AI Technical Summary

Problems solved by technology

[0003] When the existing sedimentation sewage treatment device is in use, when the sewage is injected into the sedimentation tank, the sewage will generate a large impact force, and the impact force will rush into the pool, which will cause the water in the sedimentation tank to slosh, thus making the bottom of the sedimentation tank The precipitated impurities are washed up, so that the impurities pollute the water above the sedimentation tank again, affecting the sewage sedimentation effect. At the same time, the existing sewage treatment devices with water buffering function generally have a relatively simple buffer mechanism, and the buffering effect is not good.
