High-speed settling separation device

Abstract

The invention relates to the technical field of sewage treatment equipment and relates to a high-speed settling separation device. The high-speed settling separation device comprises an outer cylinderbody, a first-layer sleeve, a second-layer sleeve, a third-layer sleeve, a bottom mud scraping assembly, a transmission connection part, a power driving device and a top mud scraping assembly, wherein the outer cylinder is sequentially and internally sleeved with the first-layer sleeve, the second-layer sleeve and the third-layer sleeve from inside to outside, an opening of the first-layer sleevefaces upwards, openings communicated with the inner cavity of the second-layer sleeve are formed in the upper and lower ends of the second-layer sleeve, and an opening of the third-layer sleeve facesdownwards. By sequentially arranging three layers of the sleeves in the outer cylinder body in a sleeving manner, sewage can slowly flow into the outer cylinder body, and the water velocity is low, so that the static settling separation can be simulated to a great extent, meanwhile, the flowing route can be extended, adequate reaction is realized, a good settling separation effect can be achieved, the sewage discharging and overflowing at the top, the sewage discharging and back flushing at the bottom and the discharging of clean water at the middle-upper part can be synchronously realized, the standing waiting is not required, and continuous operation of a system can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, and relates to a high-speed sedimentation separation device. Background technique [0002] The settling tank is a commonly used process equipment in the sewage treatment system. In the actual operation process, after coagulation and flocculation, the heavy particles in the sewage will settle to the bottom of the tank under the action of gravity, forming a mud layer at the bottom of the tank, and the light particles float on the surface If it cannot be discharged in time, it will enter the subsequent treatment equipment with the water flow, affecting the operation of the equipment and the quality of the effluent. At present, the traditional settling tank has a single structure. If it waits to stand for stratification, it requires a lot of manpower and material resources, and the standing time is long, so the efficiency is not high.
