Abstract

UN APARATO PARA FILTRAR LAS SUSPENSIONES CON DISCOS VERTICALES ROTATORIOS Y ANULARES (4), CUBIERTOS CON UN MATERIAL DE FILTRO Y PARCIALMENTE SUMERGIDOS EN LA SUSPENSION A FILTRAR. CADA DISCO ESTA PROVISTO DE UN NUMERO DE CAVIDADES (22) PARA RECIBIR EL FILTRADO DE LA SUSPENSION AL ROTAR EL DISCO. LAS CAVIDADES DE CADA DISCO SE COMUNICAN CON UNA CAMARA CENTRAL DE FILTRADO (7) A TRAVES DE CAMARAS DE ACUMULACION RESPECTIVAS (30) FORMADAS A MODO DE PARED EN LA CAMARA DE FILTRADO. CADA CAMARA DE ACUMULACION DE CADA DISCO SE EXTIENDE A MODO DE EJE HASTA PASADO EL DISCO, Y TIENE UNA SALIDA (32) LA CUAL TAMBIEN SE EXTIENDE A MODO DE EJE PASADO EL DISCO. LA VENTAJA ES QUE UNA FRACCION BRUTA Y MAS CONCENTRADA DE LA SUSPENSION PUEDE SER CONSEGUIDA.
