The invention relates to a device (1) for separating a substance into two phases, which device (1) comprises a screw conveyor (5) including a shaft and at least one screw (5) which is mounted on said shaft, which screw conveyor extends between an intake opening (9) for the substance and an outlet opening (16) for one of said two phases, as well as a cylindrical screen (10) provided with screen openings (11), within the screw conveyor (5) is rotatably disposed for conveying the substance in a direction of transport from said intake opening (9) to said outlet opening (16) via flow surfaces lying in a radial plane between said shaft, two successive screw threads in said radial plane and the screen, and for discharging the other one of said two phases via said screen openings (11), wherein the screw length of the screw conveyor (5) is determined by the length of the screen within which the screw extends, and wherein the flow surface area increases along the entire screw lenth, seen in the direction of transport.
L'invention concerne un dispositif (1) destiné à séparer une substance en deux phases. Ce dispositif (1) comprend un transporteur à vis (5) comprenant un arbre et au moins une vis montée sur cet arbre. Ledit transporteur est installé entre une ouverture d'entrée (9) destinée à cette substance et une ouverture de sortie (16) destinée à l'une des deux phases. Le dispositif de l'invention comprend également un tamis cylindrique (10) muni d'ouvertures de tamis (11), et dans lequel le transporteur à vis (5) est disposé rotatif en vue de transporter la substance en question dans un sens de transport depuis ladite ouverture d'entrée (9) jusqu'à ladite ouverture de sortie (16) par l'intermédiaire de surfaces d'écoulement disposées dans un plan radial entre l'arbre, deux filetages de vis successifs et le tamis. Le transporteur à vis (5) permet également d'évacuer l'autre phase par l'intermédiaire des ouvertures de tamis (11), la longueur de vis dudit transporteur variant en fonction de la longueur du tamis dans lequel se prolonge la vis. Vue dans le sens de transport, la zone de surface d'écoulement augmente sur toute la longueur de la vis.
