Abstract

L'invention concerne une machine configurée sous la forme d'une colonne de flottation pneumatique, comprenant : un logement qui est constitué d'une partie supérieure élargie, et d'une partie inférieure ; un tuyau interne qui est disposé dans la partie supérieure élargie, et qui divise la partie supérieure élargie du logement en chambres de flottation de base et de flottation ultérieure (1, 3), et ; un récipient de collecte de mousse qui se présente sous la forme d'une rigole ayant l'aspect d'un pignon, et qui comporte des éléments d'appui opposés (7) servant à l'évacuation du produit alvéolaire. De plus, le récipient de collecte de mousse est de préférence disposé sur la face externe du tuyau interne, dans la partie supérieure élargie du logement, entre les chambres de flottation de base et de flottation ultérieure (1, 3), et l'inclinaison du fond dudit récipient est comprise entre approximativement 45° et approximativement 60° par rapport à l'horizontale. Cet angle garantit une transportabilité optimale du produit alvéolaire. L'objectif de cette invention est d'accroître la productivité de ladite machine, en fonction du produit alvéolaire, par suppression du processus de mélange des produits alvéolaires issus des chambres de flottation de base et de flottation ultérieure (1, 3) à la surface de la pulpe, et suppression de la destruction mutuelle des aéroflocons dans la couche de mousse. Dans la machine selon l'invention, le mélange des produits alvéolaires issus des chambres de flottation de base et de flottation ultérieure (1 ou 3) sur la surface de la pulpe, ainsi que la collision et la destruction mutuelle des aéroflocons dans la couche de mousse sont évités dans la mesure où les produits alvéolaires issus des chambres de flottation de base et de flottation ultérieure (1, 3) sont introduits dans le récipient de collecte de mousse par deux côtés, notamment par le côté externe et le côté interne.
