Abstract

L'appareil centrifuge à contre-courant selon la présente invention comporte un tambour rotatif 12 monté sur un arbre 11 et une multiplicité d'éléments annulaires 23 à profil en V disposé de manière à définir des fentes 24. Un liquide léger est introduit dans la partie périphérique du corps rotatif par un tube d'arrivée 18 tandis qu'un liquide lourd est introduit dans la partie centrale du corps rotatif par un tube d'entrée 17 le liquide lourd et léger s'écoule à contre-courant à travers les fentes entre les éléments annulaires sous l'effet de la force centrifuge produite par la rotation du corps rotatif le pouvoir d'extraction étant ainsi amélioré et l'accumulation des matières solides entraînées dans la charge pouvant être évitée.
