Problems solved by technology

[0003] When purifying sewage, a certain pretreatment process is required to remove larger impurities in the sewage. However, the current sewage pretreatment device is likely to cause blockage of the filter plate during use, thereby affecting the normal flow of water. Through the mesh, the effect of sewage pretreatment is not ideal

Abstract

A sewage purification pretreatment device, comprising a box body, a filter screen plate is horizontally arranged in the box body, sliders are fixedly installed at the left and right ends of the filter screen plate, slide grooves are longitudinally arranged on the left and right side walls of the box body, and the slide block Slidingly installed on the chute; fixed plates are symmetrically arranged on the left and right inner walls of the box body, and buffer springs are arranged between the fixed plate and the filter plate; the nozzle pipe is covered with a pipe sleeve, and the pipe sleeve is fixed at the bottom of the fixed plate. A flushing nozzle is installed at the upper end of the spray pipe; a connecting rod is provided at the left end of the telescopic hydraulic cylinder, a brush plate is fixedly installed at the left end of the connecting rod, and a brush is provided at the bottom of the brush plate; Cleaning the sundries attached to the screen plate can effectively dredge the mesh holes of the filter screen plate, and the flushing nozzle sprays water on the filter screen plate obliquely to realize the flushing of the filter mesh holes in the filter screen plate, effectively preventing the mesh The clogging of the sewage greatly improves the effect of sewage pretreatment.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a sewage purification pretreatment device. Background technique [0002] Water treatment is the process of removing some harmful substances that are not needed for production and life in water through physical, chemical and biological means. It is the process of sedimentation, filtration, coagulation, flocculation, corrosion inhibition and The process of water quality conditioning, such as scale inhibition, is closely related to water in social production and life. Therefore, the field of water treatment involves a wide range of applications and constitutes a huge industrial application. [0003] When purifying sewage, a certain pretreatment process is required to remove larger impurities in the sewage. However, the current sewage pretreatment device is likely to cause blockage of the filter plate during use, thereby affecting the normal flow of water. Through ...
