Rotatable tilted plate settlement device

Abstract

The invention relates to a rotatable tilted plate settlement device, which comprises a frame and a group of tilted plates arranged in the frame at intervals, wherein one side edge of the tilted plate is hinged with the frame, and the tilted plates are connected with a driving mechanism which allows the tilted plates to rotate around a hinged part; a positioning piece capable of keeping adjacent distance is arranged between adjacent tilted plates; the driving mechanism comprises a connecting rope and rotating wheels arranged on the frame, two side frames in the motion direction of the tilted plates are at least provided with a pair of rotating wheels, one end of the connecting rope is fixed and wound on the rotating wheels, while the other end is fixed on the tilted plates; and the frame is provided with a connecting rope guide wheel matched with the rotating wheels, and the middle part of the connecting rope rounds the connecting rope guide wheel. After the structure of the rotatable tilted plate settlement device is improved, the tilted plates can rotate periodically as required, sediment on the tilted plates fall off and is peeled off from the tilted plates after the rotation, thus the phenomena of blockage and crush of the tilted plates of a settlement tank are effectively avoided; besides, the rotatable tilted plate settlement device has the characteristics of high load and short water force residence time, can achieve efficient separation of mud and water, and has low manufacturing cost and good settling separation effect.

Description

technical field [0001] The invention is a rotatable slant plate sedimentation device for sewage and water supply treatment, especially suitable for capacity expansion and upgrading of existing sedimentation tanks in water supply projects, urban sewage treatment, and industrial wastewater treatment, as well as newly-built waterworks and sewage treatment plants where land is in short supply. High-efficiency mud-water separation structures for factories (stations). Background technique [0002] At present, the level of urban sewage treatment technology in my country is relatively low, and most of the existing urban sewage treatment plants are secondary biological treatment processes, facing the upgrading and transformation situation of advanced treatment and reuse of phosphorus and nitrogen removal, and the improvement of its phosphorus and nitrogen removal functions is inevitable To achieve this by increasing the processing capacity of the system, the ordinary secondary settlin...
