Industrial sewage flocculation and sedimentation device

Abstract

The invention discloses an industrial sewage flocculation and sedimentation device. The lower part of a driving motor is rotatably connected with a driving shaft, a bearing of the driving shaft is rotatably connected with a device body, the upper part of the driving shaft is fixedly connected with a first bevel gear, and a second bevel gear is fixedly connected with a driven shaft; the end portionof the driven shaft sleeves the lower end of a boom, the upper end of the boom is fixedly connected with the device body, the other end portion of the driven shaft is rotatably connected with the device body, the driven shaft is fixedly connected with an eccentric wheel, a clamping groove is formed at the edge of the eccentric wheel, the upper surface of a sealing plate is clamped in the clampinggroove, and the edge of the sealing plate is tightly and slidably connected with the inner wall of the device body. The device drives a stirring rod to rotate by the rotating driving shaft, so that aflocculating agent and sewage are fully mixed for flocculation, the sealing plate moving up and down back and forth makes the pressure of the lower part of the device body increase and reciprocate toopen a rotating plate, the flocculated clean water enters the upper part of the device body through a guide pipe and a filter screen and is drained from a drain pipe, flocculates and water liquid canbe separated, the sewage can be recycled, and water resources can be saved.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a flocculation and sedimentation device for industrial sewage. Background technique [0002] With the development of science and technology, the direct utilization of sewage has become possible, and the sewage source heat pump system is used to utilize the urban primary sewage. There are many ways to treat sewage, which can be generally classified into physical methods, chemical methods and biological methods. Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. The role of the sewage treatment station is to treat production and domestic sewage to meet the specified discharge standards, and it is an important facility for environmental protection. Sewage treatment stations in industrially developed countries are already very common. Most of the industrial sewage is settled and removed by adding floc...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing industrial sewage flocculation and sedimentation devices use natural sedimentation to separate the flocs from the water. The separation time is long and the treatment efficiency is low. Moreover, the water and flocs cannot be fully separated through natural sedimentation, and the separation effect is not good.
