Superfine grille capable of achieving self sewage disposal

Abstract

The invention relates to the field of sewage treatment, in particular to a superfine grille capable of achieving self sewage disposal. The superfine grill is composed of an outer wall, a water inlet, a water outlet, a superfine grill body, a cleaning brush, a rotating shaft, a slag outlet, a driving motor, a water distributing weir and necessary fastening parts. According to the technical scheme, an existing arc-shaped grille is improved, the existing open-type grille is designed to be of a closed structure, the problems that when the grills is used, field assembly is troublesome, the occupied area is large, the treatment efficiency is low, and transportation is inconvenient are solved, and the usage safety is enhanced; meanwhile, the cleaning brush is additionally arranged in a cleaner, impurities remained on the grille in sewage can be removed at any time while the sewage is filtered, the filtering speed is guaranteed, and the filtering efficiency is improved; in addition, the usage load of the grille is reduced, and the service life of the cleaner is prolonged.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a self-cleaning ultrafine grid. Background technique [0002] With the increasing scarcity of fresh water resources on the earth, the problem of water shortage is highlighted, and more and more people realize the importance of fresh water resources. Advocating water conservation, purifying various types of water, achieving up-to-standard discharge, and reusing water resources are one of the effective ways for us to save water. At present, in the process of water treatment, no matter whether membrane treatment technology or filter filtration technology is adopted, the sewage needs to be pretreated before filtering, and the large particles of impurities, entanglements, floating objects and other substances in the sewage are filtered. , to prevent the filter tube of the terminal filter equipment from clogging, and to ensure the service life of the filter equipment. [0003] Most of...

AI Technical Summary

Problems solved by technology

A driving motor and a cleaning shaft driven by the driving motor are installed at a specific position in the rotary decontamination machine, and a pressure plate is installed on the cleaning shaft, and a nylon cleaning wire is installed on the pressure plate; this type of rotary decontamination machine has a high cost , the price is more expensive, and it is inconvenient to move and install, so it is not suitable for some specific occasions

[0005] The curved grille decontamination machines sold in the market are usually split and open design, and the components need to be assembled on site according to the site conditions, and the construction process is relatively complicated; at the same time, the open design has a high risk of physical injury Potentially dangerous; the simple design of this curved grille can only meet the cleaning conditions for cleaning rake teeth, but the effective filtering area is small, and the water distribution is uneven, resulting in uneven filtering load of the grille, which may make some grilles The blocking is serious and the filtering effect is lost, which affects the filtering speed of the grille
