Abstract

Se describen un método y aparato para reducir el espesor de una capa de pre-recubrimiento (57) acumulada en la superficie de filtración (56) de un disco de filtro (12) a partir de una suspensión que contiene sólidos en una cuenca (40) de un filtro de disco, dicho filtro de disco teniendo dos o más discos de filtro dispuestos en un eje (10) y entre éstos al menos un conducto de caída (38) proporcionado con un raspador (20) en ambos lados, cuyo raspador (20) raspa la torta filtrada de la suspensión en las superficies de filtración (56) de los discos de filtro (12) hacia el conducto de caída (38), por medio de cuyo raspador (20) el espesor de capa del pre-recubrimiento (57) en la superficie de filtración (56) se reduce al acortar la distancia entre las puntas de los raspadores (20) y la superficie de filtración (56), y la reducción de espesor del pre-recubrimiento (57) se logra para los pre-recubrimientos (57) en la superficie de filtración (56) de los dos discos de filtro (12) en ambos lados del conducto de caída (38) de manera no simultánea.
