FILTERING ABSTRACTION INTAKE ON MOUNTAIN AND FOOTHILL RIVER PARTS Russian patent published in 2017 - IPC E02B9/04 E03B3/32 

FIELD: mining.

SUBSTANCE: invention is intended for water abstraction for industrial, agriculture, drinking water supply systems on the foothill and mountain river parts, transporting a considerable amount of suspended and bottom sediment in high water. Filtering abstraction intake on the concave bank of the river curved section 5 includes filter plates 1, behind which there is a water-intake gallery 2, channel for removal of filtered water 3 from the swimming pool for water heating 4. Flow properties on curves, transverse circulation can protect the filter plates from clogging, because of the small plate filtration velocity compared to a significant longitudinal and radial velocities, on the filter plate walls suspended and bottom sediments will not be deposited.

EFFECT: steady intake of filtered water in mountainous and foothill rivers conditions with abundant sediment content, as well as increased efficiency and reliability of its work for the supply of industrial, agricultural and domestic water supply systems.
