Multi-stage efficient filtering device used for industrial sewage treatment

Abstract

The invention discloses a multi-stage efficient filtering device used for industrial sewage treatment in the technical field of water treatment equipment. The multi-stage efficient filtering device comprises a filtering shell, wherein a water inlet pipe is arranged on one side wall of the filtering shell, a drainage hopper is arranged on the other side wall of the filtering shell, a two-stage filter screen and a filtering component are respectively arranged at the communicated part of the water inlet pipe and the drainage hopper and the filtering shell, a filter screen is arranged at a port atthe upper part of the water inlet pipe, an end cover and a rotating motor are respectively arranged on the side walls of two ends of the filtering shell, an observation window is arranged on the outer wall of the end cover, a rotating shaft is transversely inserted into the filtering shell, two groups of driving bevel wheels are arranged on the outer wall of the rotating shaft, a driven bevel wheel is meshed above the rotating shaft by the two groups of driving bevel wheels, discharged water source meets the discharge standard and cannot pollute the environment; multi-stage filtering ensuresthe service life of the equipment, the sewage treatment effect is thorough, and overhauling is convenient.

Description

Technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a multi-stage high-efficiency filter device for industrial sewage treatment. Background technique [0002] Industrial sewage refers to the waste water, sewage and waste liquid produced in the industrial production process, which contains industrial production materials, intermediate products and products that are lost with water, and pollutants generated during the production process. If it is directly discharged into the river, it will seriously pollute the environment and cause great harm to the human body. Therefore, whether the discharged water after sewage treatment meets the standard directly depends on the sewage treatment equipment, and the filter device, as the process equipment in the sewage treatment equipment, plays a vital role in the entire sewage treatment process. Insufficient filtration may cause sewage The overall quality of the treated material is...

AI Technical Summary

Problems solved by technology

Although it can treat sewage very well, it only has one-stage filtering device. Obviously, for sewage containing more solid impurities, its filtration speed is relatively slow, which reduces the working efficiency of filtration and makes the effect of sewage treatment not very thorough. , It also has a great impact on the service life of the filter device, increasing the maintenance cost
