Abstract

Séparateur d'air rotatif destiné à éliminer l'air d'un liquide coloré de couchage du papier. Il comprend une cuve cylindrique qui tourne autour d'un axe vertical et qui reste constamment pleine. Une fraction du liquide chargée d'air ou de mousse est extraite de la région centrale de la cuve à la partie supérieure de celle-ci, tandis qu'une prise non rotative soutire le liquide exempt d'air d'une région voisine de la paroi de la cuve située à proximité de sa partie inférieure. Application aux coucheuses ou façonneuses qui traitent le papier de façon à l'enduire d'une couche contenant une charge ou du kaolin.Rotary air separator designed to remove air from a colored paper coating liquid. It includes a cylindrical tank which rotates around a vertical axis and which remains constantly full. A fraction of the air-laden or foam-laden liquid is drawn from the central region of the vessel at the top thereof, while a non-rotating intake draws the air-free liquid from a region adjacent to the vessel. wall of the tank located near its lower part. Application to coaters or moulders which treat the paper so as to coat it with a layer containing a filler or kaolin.
