Description

Technical Field

[0001] The utility model relates to the technical field of non-stop wastewater treatment, in particular to a non-stop environmental wastewater grid filter. Background Art

[0002] The grid filter is a grid sewage cleaning machine. It is a special water treatment equipment that can continuously and automatically intercept and remove various shapes of debris in the fluid. It can be widely used in urban sewage treatment. The grid sewage cleaning machine is composed of a unique rake tooth plant assembled into a set of rotating grid chains. Driven by the motor reducer, the rake tooth chain rotates against the direction of the water flow. When the rake tooth chain runs to the upper part of the equipment, due to the guidance of the groove wheel and the curved rail, each set of rake teeth produces a relative self-cleaning movement, and most of the solid matter falls by gravity. The other part relies on the reverse movement of the sweeper to clean up the debris stuck on the rake teeth. In terms of the direction of water flow, the rake tooth chain is similar to the grid. The rake tooth gap assembled on the rake tooth chain shaft can be selected according to the use conditions. When the rake teeth separate the solid suspended matter in the fluid, the water can flow smoothly. The whole working process is continuous or intermittent.

[0003] The existing non-stop environmental wastewater screen filter still has some shortcomings, such as: 1. After the debris is cleaned, it is not convenient to discharge the debris from the inside of the machine body, which leads to blockage during discharge; 2. When cleaning, high-pressure water is generally sprayed to the grab chain of the screen filter through the water spray part to wash the grab chain, but the brush roller is not used to clean the grab chain, and the grab chain is only cleaned by the high-pressure water sprayed by the water spray part, which easily leads to poor cleaning effect. For this reason, a non-stop environmental wastewater screen filter is designed. Utility Model Content
