Sewage filter of industrial pipeline

Abstract

The invention discloses a sewage filter of an industrial pipeline. The sewage filter comprises a shell, wherein a water inlet and a water outlet are formed in the shell; a coarse filter core and a fine filter core are arranged in the shell up and down in sequence; a first baffle is arranged at the connection part of the coarse filter core and the fine filter core; the water inlet is formed above the first baffle; a second baffle is arranged at the bottom of the fine filter core; the water outlet is formed between the first and second baffles; the bottom of the coarse filter core is communicated with the fine filter core; a waste collection mechanism is arranged in the fine filter core; a waste exhaust opening is formed in the side of the bottom of the shell; by arranging the coarse filter core and the fine filter core, the sewage can be filtered repeatedly and solid grains of different diameters can be filtered orderly; the purification efficiency of the sewage is improved; the waste collection mechanism can be used for automatically collecting solid grains of small diameters in the fine filter core; and the blockage of the fine filter core is avoided and the labor intensity of manual cleaning is reduced.

Description

technical field [0001] The invention relates to a filter, in particular to a sewage filter for industrial pipelines. Background technique [0002] Classification of industrial wastewater: First, it is classified according to the chemical properties of the main pollutants contained in industrial wastewater. Inorganic wastewater mainly contains inorganic pollutants, and organic wastewater mainly contains organic pollutants; the second is based on the products of industrial enterprises. and processing objects, such as metallurgical wastewater, papermaking wastewater, coking gas wastewater, metal pickling wastewater, chemical fertilizer wastewater, textile printing and dyeing wastewater, dye wastewater, tannery wastewater, pesticide wastewater, power station wastewater, etc.; Classification of the main components of pollutants, such as acidic wastewater, alkaline wastewater, cyanide-containing wastewater, chromium-containing wastewater, cadmium-containing wastewater, mercury-con...

AI Technical Summary

Problems solved by technology

The filter element of the traditional sewage filter for industrial pipelines is easily blocked by solid phases of large and small diameters in the sewage during long-term use, which reduces the purification efficiency of sewage, and it is easy to cause blockage of pipeline transportation during pipeline transportation. It is difficult to disassemble, replace and clean the filter, because of the uninterrupted filtration of sewage, it is necessary to manually clean the filter regularly
