Small and medium-sized riverway upstream water-soil separation device

Abstract

The invention discloses a small and medium-sized riverway upstream water-soil separation device comprising a river interception bin; a sludge discharge bin and a filtered water discharge bin are fixedly arranged in a river interception plate, a piston pipeline is arranged on the upper portion of the filtered water discharge bin, and a negative pressure pipeline is arranged on the lower portion ofthe filtered water discharge bin; a spiral blade is arranged in the sludge discharging bin, a water inlet is formed in the bottom of the sludge discharging bin, a filtering opening is formed between the sludge discharging bin and the negative pressure pipeline, and the filtering opening is covered with a sludge filtering layer; a piston is arranged in a piston pipeline of the filtered water discharge bin, a lifting rod is arranged on the upper portion of the piston, a rack is arranged on the lifting rod in the length direction of the lifting rod, an incomplete gear meshed with the rack is arranged above the filtered water discharge bin, a plurality of through holes are formed in the piston, and turnover covers are hinged to the through holes. Sand and sludge in a riverway can be continuously filtered, and water and soil loss and downstream riverbed lifting are avoided.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a water-soil separation device in the upper reaches of a medium-sized river course. Background technique [0002] Due to excessive land development, the vegetation in the middle and upper reaches of the river is destroyed, and the water and soil loss is serious. Especially after the heavy rain, the surface sediment is rolled up and flows downstream along the river, blocking the river along the way, and the downstream river bed is raised, which is likely to cause floods in the downstream area. It causes serious damage to human property and destroys the ecological environment. [0003] The treatment of river water containing a large amount of sediment is a difficult water conservancy problem in the world. Even if the river water containing a large amount of sediment is stored in the reservoir to naturally settle the sediment after the dam is built, it will cause ex...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved in the present invention is that the river water in the upper reaches of the river will bring the sediment to the downstream, causing water and soil loss, and a medium and small water and soil separation device for the upper reaches of the river is provided.
