Abstract

UN APARATO PARA FILTRAR LIQUIDOS, COMO SUSPENSIONES DE PULPA FIBROSAS O AGUA CONTAMINADA, INCLUYE DISCOS FILTRANTES HUECOS ANULARES (5), CADA UNO DE LOS CUALES TIENE DOS PAREDES OPUESTAS, PERMEABLES DE LIQUIDOS ANULARES (6,7) CUBIERTAS CON MATERIAL FILTRANTE, ELEMENTOS DE TOBERA DE PULVERIZACION (15-17) PARA LIMPIAR EL MATERIAL FILTRANTE, Y ELEMENTOS (12) PARA PROPORCIONAR MOVIMIENTO RELATIVO ENTRE EL MATERIAL FILTRANTE Y LA TOBERA DE PULVERIZACION. LAS PAREDES ANULARES OPUESTAS DE CADA DISCO FILTRANTE ESTAN UNIDAS A LAS OTRAS SOLO EN SUS EXTREMOS EXTERIORES RADIALMENTE, MIENTRAS QUE ESTAN SEPARADAS EN SUS EXTREMOS INTERIORES RADIALMENTE, DE TAL FORMA QUE SE DEFINE UNA APERTURA ANULAR ENTRE EL INTERIOR DEL DISCO FILTRANTE Y UNA CAMARA DE FILTRADO (11) QUE SE EXTIENDE CENTRALMENTE A TRAVES DE LOS DISCOS FILTRANTES. LA TOBERA PULVERIZADORA (15-17) SE EXTIENDE DESDE LA CAMARA DE FILTRADO A TRAVES DE LA APERTURA ANULAR EN CADA DISCO FILTRANTE. COMO RESULTADO, SE PUEDE PRODUCIR UNA FRACCION FINAEXTREMADAMENTE PURA, LA OBSTRUCCION DEL MATERIAL FILTRANTE SE ANULA EFICAZMENTE, Y PUEDE AUMENTAR LA PARTE OPERATIVA DEL MATERIAL FILTRANTE.
