CENTRIFUGAL EXTRACTOR Russian patent published in 1997 - IPC

FIELD: extraction apparatuses. SUBSTANCE: centrifugal extractor contains several matched cascades and fixed housing inside which drums are revolving at high velocity; drums are rotated by common vertical shaft. Immiscible light liquid and heavy liquid are emulsified and ejected into separating chambers formed by drums and connecting passages forming ejectors in lower wall of respective drum. Light phase passes upward from one cascade to another ring-shaped passage surrounding the shaft and heavy phase lowers by gravity over vertical return passaged formed in fixed housing. EFFECT: avoidance of turbulization in separating chambers and danger of choking due to presence of solid particles in heavy phase. 6 cl, 3 dwg
