Treatment filtering device for repairing river channel

Abstract

The invention belongs to the technical field of filtering devices, and particularly relates to a treatment filtering device for repairing a river channel. The treatment filtering device comprises a trash blocking plate; a filtering groove is formed in the side wall of the trash blocking plate; the trash blocking plate is sleeved with a filter cover; matching grooves are formed in the two sides of the filter cover; an inclined face is arranged at the bottom end of one side of the filter cover; an included angle is formed between the inclined face and the face, close to the trash blocking plate, of the filter cover; a baffle is rotationally connected with the inclined face through a torsional spring; an inclined guide face is arranged at the free end of the baffle; an electric push rod is rotationally connected with the bottom end of the side wall, close to the baffle, of the filter cover; and the other end of the electric push rod is connected with the end of the baffle. According to the treatment filtering device for repairing the river channel, intercepted impurities are conveniently and rapidly fished up through the filter cover and the baffle, so that the labor burden of workers is greatly reduced; and meanwhile, the device can continuously intercept the impurities in a river, so that the restoration effect of the filtering device on the river channel is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of filtering devices, in particular to a processing and filtering device for repairing river courses. Background technique [0002] With the continuous improvement of my country's urbanization rate, the discharge of urban sewage has increased significantly, and the pollution load of urban surface water bodies has also increased. As a result, the quality of surface water is generally in the national surface water quality standard V and inferior to V. between. The river itself has shortcomings such as small water environment capacity and poor self-purification ability of the water body, which leads to an imbalance of oxygen supply and consumption in the water body, and the water body is in an anoxic or even anaerobic state. The anaerobic decomposition of organic matter will cause black odor, which will cause a crisis in the entire ecosystem, seriously affect the ecological environment, and have a great impact ...

Problems solved by technology

[0005] However, when the trash grid used for river restoration in the above-mentioned technology is used for a long time, the sundries accumulated on one side of the trash grid are not easy to clean up, which greatly increases the labor burden of the workers, and when the debris accumulates more, it will also cause the trash The sewage grid is blocked, affecting the effective filtration and cleaning of the river water
