Abstract

La présente invention concerne un dispositif à cyclone magnétique (1S) comprenant : un cyclone (1) qui est un cône tronqué dont le sommet est tourné vers le bas et qui a une base cylindrique (1b) ayant une entrée (2) sur un côté et une section conique (1c) formée en continuité avec le fond de la base cylindrique (1b) et pourvue d'une sortie inférieure (4) à proximité du sommet ; une section cylindrique (1e) qui est disposée au centre de la base cylindrique (1b) et qui est pourvue d'une sortie supérieure (3) ; et un aimant (5) qui est disposé à proximité de la circonférence externe de la base cylindrique (1b). Un floculat magnétique contenu dans un liquide à traiter (7) s'écoulant dans la base cylindrique (1b) à partir de l'entrée (2) est évacué de la sortie inférieure (4) après avoir été attiré par l'aimant (5) à proximité d'une face interne (1b1) de la base cylindrique (1b), et le liquide à traiter à partir duquel le floculat magnétique a été retiré s'écoule hors de la sortie supérieure (3) de la section cylindrique (1e).
