Eccentric-type arc-shaped movable slant board

Abstract

The invention discloses an eccentric-type arc movable slant board which can be used for accelerating the deposition process in sewage treatment process, clearing a water body, and improving the sewage treatment effect. According to the invention, thin boards are wound to be arc with different sizes, and are ranked at equal or variable distances so as to form groups; an eccentric shaft is fixed on a rotary shaft; the clearances of adjacent arc boards form a plurality of shallow layer deposition tanks; and treated water bodies and settled deposition objects move mutually and stably in the deposition shallow layers and are separated; the eccentric arc slant boars are rotated to shift radially and tangentially, so that water bodies at the shallow layers are subjected to gradient shearing transformation, and flocculant cores are in mutual contact, collide, adhere and polymerize so as to form dense flocculant bodies so as to be separated from water, and raw water is cleared and purified. The eccentric-type arc movable slant board provided by the invention can rotate around the rotary shaft, forms intense and turbulent shearing flows through rapid and reciprocating rotation left and right, is subjected to the high-speed washing effect, and can be used for eliminating possible deposition and blocking conveniently.

Description

technical field [0001] The invention relates to an eccentric arc movable inclined plate capable of accelerating the sedimentation process in sewage treatment, clarifying the water body and improving the sewage treatment effect. Background technique [0002] Inclined tube or inclined plate is one of the most extensive and mature sedimentation devices developed in shallow pond theory, and is widely used in water treatment sedimentation tanks. In the sedimentation zone of the sedimentation tank, the water body is divided into a series of shallow sedimentation layers by using inclined parallel pipes or parallel pipes (sometimes honeycomb fillers can be used), and the treated water body and the settled sediment move with each other in each shallow sedimentation layer. separate. The inclined tube sedimentation tank has the advantages of large sedimentation area, high sedimentation efficiency, short sedimentation time, and less land occupation. It is a high-efficiency sedimentatio...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the defects that the inclined tube sedimentation tank has poor adaptability to water impact load and water temperature change and the traditional inclined plate (pipe) is prone to sludge adhesion and blockage, which affects the sedimentation effect, the invention combines the shallow pool theory, dynamic coagulation, The principle of rapid flocculation and inclined plate technology changes the straight shape of the traditional inclined plate (tube), and winds the thin plate into arcs of different sizes, or circular, or semicircular, or frustum-shaped, or variable-diameter curved arcs Shape, or arc-shaped grooves and other shapes; equidistant or variable-distance overlapping arrangement into groups, eccentrically fixed on the shaft
