Abstract

Apparatus for separating liquid from a fibrous suspension comprises a hollow container having an inlet and an outlet. A hollow filter element enclosing a filtratereceiving space is rotatably mounted in the container such that an annular suspension-receiving space is defined between the walls of the filter element and the container. A discharge mechanism permits liquid filtrate to be discharged from the filtrate-receiving space at a rate sufficient to reduce the pressure in the space relative to the pressure in the suspensionreceiving space so that liquid in the fibrous suspension flows through the filter element into the filtrate-receiving space, leaving a concentrated fibrous suspension in the annular space surrounding the filter element. The annular suspension-receiving space communicates with the inlet and the outlet of the container and has a radial width that diminishes from a point adjacent the inlet circumferentially about the container toward the outlet. The radial width of the suspension receiving space abruptly increases adjacent the outlet of the container so that the pressure in the portion of the suspensionreceiving space adjacent the outlet is reduced relative to the pressure in the filtrate-receiving space. The pressure differential causes a back flow of filtrate through the filter element to wash fibers from the surface of the element and facilitate the discharge of the concentrated suspension from the container.
