Abstract

La présente invention concerne une presse à épaissir qui comprend deux rouleaux de presse rotatifs (1), qui coopèrent l'un avec l'autre. Leurs surfaces d'enveloppe (5) présentent des ouvertures ou des perforations pour éliminer le liquide d'une matière qui en est saturée (3) et qui doit être concentrée et déplacée vers l'avant entre les rouleaux de presse. Chacun de ces rouleaux (1) est entouré sur une partie de sa surface périphérique (5), y compris au moins au niveau des zones dans lesquelles il agit sur la matière en cours de concentration, par une bande sans fin de tissu filtrant (6, 7), qui passe aussi autour d'au moins un rouleau de renvoi (10; 10, 17, 18) situé à une certaine distance du rouleau de presse qui lui correspond (1) et de la matière trempée, non encore concentrée (3). Les bandes de tissu filtrant (6, 7) sont sensiblement parallèles en aval de la zone de pression, jusqu'à un poste de livraison (15, 16) de la matière concentrée.
