Abstract

Cette invention concerne un dispositif d'alimentation et d'essorage de la pâte à papier conçu pour essorer, pressurer et laver une pâte de cellulose. Ce dispositif comporte une première partie (1) permettant l'introduction de la pâte, une partie (2) conçue pour l'essorage ou le pressurage, une partie (3) permettant l'ajout de liquide détergent et le mélange avec ledit liquide, une partie (4) conçue pour l'essorage ou le pressurage final et enfin une partie (5) conçue pour l'evacuation de la matière traitée. L'essorage effectué dans la partie (2) se déroule entre un panier de tamisage convergent et un noyau de vis divergent, et l'essorage effectué dans la partie (4) se déroule entre un panier de tamisage cylindrique et un noyau de vis divergent.
