Circular suspension filtering system capable of realizing continuous operation

Abstract

The invention provides a circular suspension filtering system capable of realizing continuous operation. The circular suspension filtering system comprises a water filtering tank, wherein the interiorof the water filtering tank is divided into an upper clear water storage area, a middle filtering area and a lower water distribution area; a first fixed partition plate and a second fixed partitionplate are fixed in the lower water distribution area at a set included angle and divide the lower water distribution area into a water inlet area and a backwashing area; a third fixed partition plateand a fourth fixed partition plate are fixed in the upper clear water storage area at the same set included angle and divide the upper clear water storage area into an upper water area and a water return area; a central rod is arranged at the center of the water filtering tank; a plurality of rotary partition plates are arranged in the middle filtering area and are radially and uniformly distributed so as to equally divide the middle filtering area into a plurality of equally-divided areas, the rotary partition plates are fixed with the central rod and are driven by the central rod to rotate,and an included angle between every two adjacent rotary partition plates is equal to a set included angle; and when backwashing is carried out, a backwashing valve and a water inlet valve are opened,water in the water return area flows back downwards to realize backwashing of the filter materials in the equally-divided areas, and washed impurities are discharged through a backwashing area and a backwashing discharge pipe. The whole system runs continuously, later-period management and maintenance are omitted, and filtering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of suspension filtration, in particular to a circular suspension filtration system capable of continuous operation. Background technique [0002] Suspension filtration technology is a technology that uses a filter material with a density lower than water to reversely filter raw water (bottom-up filtration method). Filtration system, including the filter tank connected with the original water channel, the backwash system connected with the filter tank, the lower water distribution roof and the upper filter plate in the filter tank are divided into the lower water distribution area, the middle filter area and the upper clear water storage area, The middle filter area is filled with filter materials, and the bottom wall of the filter tank has a water inlet matched with the water supply pipe of the original water canal and a drain matched with the backwashing system. [0003] When the suspension filtration syst...

Problems solved by technology

[0005] The purpose of the present invention is to provide a circular suspension filter system that can operate continuously, so as to solve the problem that the existing filter system needs to close the water inlet valve during backwashing, which leads to cumbersome management and maintenance in the later stage and affects the filtration efficiency of the entire system.
