Abstract

PROCEDIMIENTO PARA DESPRENDER EN TROZOS PEQUEÑOS EL RESIDUO DE LA FILTRACION EN UN FILTRO DE EXTRACION PARA MEZCLAS LIQUIDO-SOLIDO, CON UNA CUBIERTA EXTERIOR, UNA TAPA SEPARABLE QUE TAPONA DICHA CUBIERTA EXTERIOR, UN ELEMENTO FILTRANTE EN FORMA DE TUBO QUE PENETRA DESDE LA TAPA HACIA EL INTERIR DE LA CUBIERTA ALGO SEPARADO DE ELLA, ASENTANDOSE EN LA CARA EXTERNA DE ESTE ELEMENTO FILTRANTE EL RESIDUO DE LA FILTRACION, UNA MEMBRANA QUE SE PUEDE VOLVER DEL REVES, DISPUESTA DURANTE EL FUNCIONAMIENTO DEL FILTRO ENTRE LA CUBIERTA EXTERIOR Y EL ELEMENTO FILTRANTE, UN MANGUITO DE PRESION EN LA CUBIERTA EXTERIOR PARA LA ENTRADA Y SALIDA DE UN MEDIO A PRESION, UN CONDUCTO DE ENTRADA QUE SIRVE PARA INTRODUCIR EN EL ESPACIO ENTRE LA MEMBRANA Y EL ELEMENTO FILTRANTE LA MEZCLA LIQUIDO-SOLIDO Y UN CONDUCTO DE SALIDA PARA EL FILTRADO OBTENIDO, QUE PARTE DEL INTERIOR DEL ELEMENTO FILTRANTE. SEGUN EL PROCEDIMIENTO, SE INYECTA, UNA VEZ FORMADO EL RESIDUO, A TRAVES DE LA CARA EXTERNA DEL ELEMENTO FILTRANTE, UNMEDIO A PRESION GASIFORME EN EL INTERIOR DE DICHO RESIDUO, MIENTRAS ESTE ESTE TOTAL O PARCIALMENTE RODEADO POR LA MEMBRANA REVERSIBLE.
