Abstract

Appareil destiné à éliminer une couche de matière semi-flottable en suspension d'un liquide contenu dans un réservoir. Selon l'invention, cet appareil est caractérisé en ce qu'il comprend une lame mobile le long dudit réservoir, ladite lame pouvant pivoter autour d'un axe entre une position d'extension pour laquelle elle traverse ladite couche et une position rétractée pour laquelle elle ne s'étend pas à travers ladite couche, des moyens pour déplacer ladite lame le long du réservoir, des moyens pour faire pivoter ladite lame autour dudit axe et des moyens de blocage pour bloquer ladite lame dans la position d'extension et dans la position rétractée. Extraction par solvant de produits contenus dans une phase liquide
