Sewage filtering equipment with anti-blocking function

Abstract

The invention discloses sewage filtering equipment with an anti-blocking function. The sewage filtering equipment comprises a filtering chamber, wherein a water inlet pipe and a water outlet pipe arecommunicated onto the filtering chamber; a servo double-shaft motor is arranged on the filtering chamber; each of two output ends of the servo double-shaft motor is fixedly connected with a rotating shaft; two first installing blocks and a second installing block are fixedly connected onto the inner wall of the filtering chamber; a first rotating shaft is rotationally connected between the two first installing blocks. The sewage filtering equipment has the advantages that when insoluble impurities floating on the sewage are filtered, a scraping plate is used for performing continuous scrapingon the filter screen surface; the filtering speed influence since too many insoluble impurities are adhered on the filter screen is avoided; the rotation of a second round fixing disc and a rotating rod are utilized, so that vortexes can be formed at the surface of water in the filtering chamber; the insoluble impurities floating on the water surface are gathered in the vortexes or near the vortexes; the contact of a large number of insoluble impurities and the filter screen is avoided.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage filtering device with an anti-blocking function. Background technique [0002] Sewage usually refers to polluted, domestic and production discharge water. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater; sewage treatment is to purify sewage to meet the water quality requirements of being discharged into a certain water body or reused Process; Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] The first step of the sewage treatment process needs to clean up the insoluble impurities floating on the water surface, and then carry out targeted treatment according to the different types of soluble impurit...
