Abstract

Machine à laver destinée aux industries du papier et analogues. Elle comporte un tamis filtrant incliné sans fin 12, mobile de bas en haut, destiné à séparer la pâte lavée de l'eau de lavage. Le tamis 12 défile, à contresens par rapport à la pâte, devant une arrivée de pâte chargée d'eau et devant au moins un poste de lavage où arrive un supplément d'eau de lavage. La pâte lavée est finalement tassée entre un tambour 14 et le tamis 12, ce qui la débarrasse de l'excès d'eau, puis évacuée. Grâce au mouvement à contresens du tamis et de la pâte, le trajet de lavage se trouve prolongé, ce qui permet de rendre la machine compacte.
