HYDRAULIC SEPARATOR Russian patent published in 2012 - IPC B03B5/62 

FIELD: process engineering.

SUBSTANCE: invention relates to grading particles to settling velocity, density, geometrical sizes, and may be used in mining, construction and chemical industry, etc. Proposed separator comprises cylindrical housing made up of two aligned cylinders with their bottom edges connected with separation products receivers to make housing bottom. Said housing accommodates rotary separation chambers with pairs of "П"-shape guide plates with bases directed upward and radial plates made up of two aligned cylindrical shells to make communicating vessel with said housing. It comprises shield made up of separate detachable segments of ring displacing radially, driven shaft, initial material feeder, and separation products receivers. Device to stabilise water level in separation chambers comprises branch pipe to feed and discharge water arranged over outer cylinder height from its top edge to radial plate bottom element top edge. Sections of narrow channels made up of crossing plates are arranged between cylindrical shells and pairs of "П"-shape guides. Base of every separation products receiver accommodates inclined cylinder housing rotary shaft with screw fitted thereon, parallel with cylinder bottom.

EFFECT: higher efficiency of separation.
