Filter device for treating industrial sewage

Abstract

The invention discloses a filter device for treating industrial sewage. The filter device for treating the industrial sewage comprises a tank body, an inner tank, a filter screen, a filter barrel, anarc-shaped cover plate and a first water delivering tube, wherein a water inlet tube is arranged on the left side of the tank body; a discharging end of the water inlet tube penetrates through the surface of the tank body; the surface of the left side of the inner tank is connected with the discharging end of the water inlet tube in a penetrating manner; the left end of the inner tank is fixedly connected with the inner wall of the tank body; the filter screen is connected with the outer wall of the inner tank through a limiting plate fixed internally; a mounting seat is mounted on the inner wall of the tank body; a baffle is mounted on the lower portion of the tank body in an embedded manner; sewage draining openings are separately formed in the lower surface of the tank body and the surface of the baffle; a water draining tube is mounted below the inner tank; the lower end of the water draining tube penetrates through the lower surface of the tank body; a fixing plate is arranged onthe surface of the right side of the tank body; and the arc-shaped cover plate separately penetrates through the surface of the inner tank and the surface of the tank body. According to the filter device for treating the industrial sewage, a resetting spring is compressed by the filter screen; and when the filter screen returns, scummings on the surface of the filter screen are scraped off by a scraper blade, meshes of the filter screen are prevented from being blocked, and the filter efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of industrial sewage treatment, in particular to a filter device for industrial sewage treatment. Background technique [0002] With the continuous improvement of the level of social and economic development, the development of industrial enterprises in many areas of our country is accelerating, which is conducive to increasing the income of our national economy, but it also brings certain environmental problems. If industrial sewage is not properly treated, it may pollute the surrounding environment and affect the domestic water supply of the surrounding residents. When industrial sewage is treated, the sewage is filtered, and the residue in the sewage is intercepted and filtered. The existing filtering devices have the following problems when filtering industrial sewage: [0003] 1. The filtration method cannot be reasonably adjusted according to the flow of sewage, resulting in incomplete filtration; ...

Problems solved by technology

[0006] The purpose of the present invention is to provide a filter device for industrial sewage treatment, to solve the problem that the filtering method cannot be adjusted reasonably according to the flow of sewage in the above-mentioned background technology, resulting in incomplete filtering; when filtering, the filter screen cannot be timely The scraping process makes the filter screen easy to be blocked, which affects the subsequent filtration efficiency; it is inconvenient to recoil the residue on the filter screen, and the filter screen needs to be removed for cleaning, which is time-consuming and labor-intensive.
