DEVICE AND METHOD FOR CLEANING PROCESS SOLUTION BY GRAVITATIONAL SETTLING Russian patent published in 2016 - IPC B01D21/02 C01F7/46 

FIELD: cleaning device.

SUBSTANCE: invention relates to the purification process of a solution containing solids. Apparatus comprises a reservoir (10) having a base (12) and side wall (14) defining an inner volume for holding processing solution (22) and for gravitational settling of solids in the solution, whereby a purified solution (30) at the top area of internal volume and the suspension (40) in the lower region of the inner volume, the release of the purified solution (20) in or near the upper region of the inner volume for the extraction of the purified solution, the release of slurry (16) within or near the bottom region of internal volume to extract slurry nonlimiting open to said inner volume. Also, the device contains elements that move solids which extend transversely to and fixed relative to the reservoir (10), said elements are in the internal volume for guiding deposited solids and/or precipitation of solids near the side wall or base to the path of movement (F ) slurry extracted from the outlet of the slurry.

EFFECT: invention provides an increase in the concentration of solids in the stream is extracted from the reservoir of the device.
