Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filtration, and more particularly to a coarse filtration device for discharge from a municipal road drainage channel. Background Art
[0002] Through the filtering medium, the device can effectively intercept solid particles, suspended matter and other impurities in rainwater or sewage, preventing these impurities from entering the drainage pipes and causing blockage or damage. Through filtration, the water quality can be improved and the pollution of sewage to the environment can be reduced. For rainwater, the filtered water can be directly discharged into the river, and for sewage, the filtered water can more easily enter the sewage treatment plant for further treatment. Some filtering devices are designed with easy-to-clean structures, such as lifting mechanisms, which can easily clean impurities accumulated on the filter medium, reduce the labor intensity of workers, and reduce the risk of workers contracting pathogens.
[0003] Existing technology is inadequate: If the coarse filter fails to effectively filter impurities, these impurities (such as leaves, plastic bags, and paper) will enter the drainage pipes. Over time, these impurities will gradually accumulate in the pipes, causing blockages. Clogged pipes will seriously affect drainage efficiency and may even cause sewage overflows, polluting roads and the surrounding environment. Because garbage cannot be automatically replaced, garbage will gradually accumulate on the filter device, ultimately resulting in a significant decrease in filtration effectiveness. As garbage accumulates, the filter device may gradually become ineffective and unable to effectively intercept impurities in the water. As garbage accumulates on the filter device, its filtration capacity will gradually weaken, resulting in reduced drainage efficiency. Utility Model Content

[0027] The working principle of the present invention is as follows: open a drain cover in a sewer that needs to be filtered, and then place the drain trough 1 into the drain. When the rainwater trough begins to accumulate water, the water flows through the inner wall of the drain trough 1. When there is garbage, it begins to be filtered through the L-shaped filter plate 3 on the inner wall of the drain trough 1. The motor 110 is started once every period of time through timing. When the motor 110 starts to start, it drives the second horizontal support column 107 to rotate on the inner ring side walls of the second support column 103 and the first support column 102. The first winding roller 108 and the second winding roller 109 fixed on the outer ring side walls of the second horizontal support column 107 also begin to rotate.

The anti-falling partition 301 is to prevent the garbage on the surface of the L-shaped L-shaped filter screen plate 3 from falling into the canal. After repeating the operation several times, the telescopic push rod 117 stops working, and the motor 110 starts to retract and release the first rust-proof steel wire rope 111 and the second rust-proof steel wire rope 112 to put the L-shaped L-shaped filter screen plate 3 back in place. The garbage pushed out is all accumulated in the garbage receiving and placing plate 202 fixed on the side of the protective cover 2, and is cleaned regularly by the environmental protection and sanitation staff.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
