Abstract[English]
A scroll assembly for a centrifuge that includes at least one lamellae pack assembly (11) proximate the first end of the scroll. The lamellae pack assembly (11) may have a plurality of lamella plates and be positioned upstream of a weir (31) or an effluent exit port (4) that permits a liquid fraction (33) of said infeed slurry to discharge from the centrifuge. The lamella plates are preferably configured and arranged to bias fine solids (35) entrained within the liquid fraction (33) radially-outwardly or at least hinder their radially-inwardly migration as the liquid fraction (33) passes through the lamella plates and before the liquid fraction passes the weir (31) or effluent exit port (4), in order to produce discharged clarified liquids (36) which are substantially-free of the fine solids (35).[French]
L'invention concerne un ensemble vis d'extraction pour une centrifugeuse comprenant au moins un ensemble de paquets de lamelles (11) à proximité de la première extrémité de la vis d'extraction. L'ensemble du paquet de lamelles (11) peut comporter plusieurs plaques à lamelles et être placé en amont d'un déversoir (31) ou d'un orifice de sortie de l'effluent (4) qui permet à une fraction liquide (33) de ladite bouillie d'alimentation de s'évacuer de la centrifugeuse. Les plaques à lamelles sont de préférence configurées et disposées de manière à orienter les solides fins (35) entraînés dans la fraction liquide (33) radialement vers l'extérieur ou au moins à empêcher leur migration radiale vers l'intérieur lorsque la fraction liquide (33) passe à travers les plaques à lamelles et avant que la fraction liquide ne passe le déversoir (31) ou l'orifice de sortie de l'effluent (4), afin de produire des liquides clarifiés (36) déchargés qui sont substantiellement exempts de solides fins (35).
