Microporous filter cloth filtering machine

Abstract

The invention relates to a microporous filter cloth filtering machine, which belongs to the field of sewage filtration treatment. The position of a clean water outlet is lower than the position of a water inlet; two pieces of circular filter cloth are fixed on two faces of a filter cloth frame; an inserting slot is formed at the bottom of the filter cloth frame to form a filtering cavity; the end of a sewage suction pipe unit of the filter cloth is supported and fixed in a box body; and the sewage suction pipe unit is positioned on the circle center of the filter cloth. A suction disc component is tightly adhered to the filter cloth on the two faces of the filtering cavity, and the length of the suction disc component approximates to the radius of the filter cloth. The filtering cavity, the suction disc component, the sewage suction pipe unit and a water outlet branch pipe form a filtering unit; N filtering units are vertically distributed in parallel in the box body along the sewage suction pipe unit. The sewage suction pipe unit of the filter cloth and a sewage suction pipe at the bottom of the box are connected with a sewage suction pump through a back-suction main pipeline. A transmission chain wheel, a transmission chain and a driving motor form a transmission mechanism. Compared with the equipment having the same performance, the microporous filter cloth filtering machine provided by the invention has a smaller volume, lower production and running cost, and higher reliability and is simpler in a manufacturing process.

Description

technical field [0001] The invention relates to a microporous filter cloth filter, which is suitable for deep filtration treatment of sewage in sewage treatment plants, process water reuse filtration, and reclaimed water reuse filtration, and belongs to the field of sewage filtration treatment. Background technique [0002] At present, the existing microporous filtration equipment for sewage filtration treatment is divided into two main structures. The filter equipment of the two structures has a hollow rotatable drum in the middle, and there are multiple openings on the drum, and N filter fans are radially connected to each other on the opening to form a circular filter chamber. The filter chambers are distributed on the drum parallel to the longitudinal direction of the drum. The first structure is that the raw water to be treated enters the filter chamber made of filter cloth through the opening on the drum through the middle drum, and then the raw water flows out throug...

AI Technical Summary

Problems solved by technology

[0004] 1. Since there is a hollow drum, in order to increase the effective filtration area, the diameter of the filter fan is large, and the disc filter equipment is large in volume and occupies a large area

[0005] 2. Since the drum needs to rotate, the requirements for the hardness and sealing of the filter fan support are high, which makes the design of the support complicated, more materials used, and high cost

[0006] 3. Since the backwashing or backsuction system needs to rotate the drum to effectively clean the filter cloth, the motor power of the rotating drum is large and the operating cost is high

[0007] 4. It must be shut down to replace the filter unit
