Sewage filtration device convenient to mount and clear

Abstract

The invention discloses a sewage filtration device convenient to mount and clear. The device comprises a first mounting rack, filter nets, a first mounting rod, a splicing groove, first mounting rotating shafts and fixing plates, wherein the filter nets are mounted at the upper part and the lower part of the first mounting rack, the splicing groove is formed in one side of the first mounting rod,and each fixing plate is welded on one side of each of the first mounting rotating shaft. The sewage filtration device is scientific and reasonable in structure and safe and convenient to use; a grating and the filter nets are arranged, large-size solid wastes in sewage are cleared by the grating, part of small-size solid wastes in the sewage are cleared by the filter nets, and following sewage treatment is facilitated; second mounting rotating shafts and a power rotating shaft are arranged, the second mounting rotating shafts and the first mounting rack can be effectively driven to rotate through the power rotating shaft, one filter net with excessive solid wastes attached to the surfaces is rotated to the upper part, clearing of the solid wastes is facilitated, and besides, the other filter net can continuously have a function of filtering the small-size solid wastes.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a sewage filter device that is easy to install and clean. Background technique [0002] Environmental engineering is a branch of environmental science. It mainly studies how to protect and rationally utilize natural resources, use scientific means to solve increasingly serious environmental problems, improve environmental quality, and promote environmental protection and social development. Waste, noise, and prevention and control technologies for radioactive substances, heat, electromagnetic waves, etc. that cause pollution. In the process of wastewater treatment, grids are usually used to filter the incoming water to prevent large volumes of solid waste from entering the waste water treatment area. Inside the reaction tank, small solid waste such as sand and gravel will still flow into the reaction tank for wastewater treatment. At present, in order to avoid t...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a sewage filter device that is easy to install and clean, which can effectively solve the above-mentioned background technology that the filter device currently on the market is difficult to directly cooperate with the grid, and the filter screen is prone to blockage of the filter screen under the large flow of water. If the situation occurs, the installation process of the existing filter is complicated, and it is difficult to clean the blocked filter in time, which will easily lead to a decrease in the flow of waste water and a decrease in the filtering effect.
