Abstract

Un aparato de filtrado (1) para separar suspensiones de fibra que comprende un filtro tubular estacionario (9) para recibir la suspensión de fibra que se va a separar en un extremo del filtro, un rotor (5) coaxial con el filtro tubular y medios de restricción del flujo (21, 23, 25, 27) que definen un pasadizo de rechazo anular (249 que es coaxial con el filtro tubular y está situado en el otro extremo del mismo para descargar una fracción de rechazo desarrollada de la suspensión de fibra del interior del filtro. Los medios de restricción del flujo comprenden un componente anular (27), preferiblemente una tira elástica, que sea dilatable y replegable, respectivamente, en la dirección radial del pasadizo de rechazo anular (24) para aumentar y disminuir, respectivamente, la superficie de la sección transversal del pasadizo de rechazo anular
