Abstract

FILTRO CONTINUO. PROCESO DE FILTRACION Y FILTROS PARA USO CON MATERIALES COMO, AUNQUE SIN LIMITARSE A, FUSIONES POLIMERICAS, QUE UTILIZAN UNA BANDA (18) DE UN MEDIO DE FILTRO CERRADO EN UN ALOJAMIENTO (10) POR MEDIO DE RODILLOS DE OBTURACION (25, 26) PARA MANTENER HERMETICAMENTE EL MATERIAL POLIMERICO DE FUGAS AL EXTERIOR DEL ALOJAMIENTO. EN UNA REALIZACION, LOS RODILLOS DE OBTURACION HACEN POSIBLE SUBIR EL MEDIO DEL FILTRO A TRAVES DEL ALOJAMIENTO CONTINUAMENTE. EN DIFERENTES REALIZACIONES, EL MEDIO DEL FILTRO PUEDE SUBIR MEDIANTE UNA BOBINA RECEPTORA (32) O MEDIANTE EL TRANSPORTE DE LOS RODILLOS DE OBTURACION Y LA VELOCIDAD DE MOVIMIENTO DEL MEDIO DEL FILTRO A TRAVES DEL ALOJAMIENTO SE PUEDE CONTROLAR PARA MANTENER UN DESCENSO DE PRESION CONSTANTE EN EL FILTRO. MANTENIENDO CONDICIONES CONSTANTES A TRAVES DEL AVANCE CONTINUO DEL MEDIO DEL FILTRO DURANTE LA FILTRACION HACE QUE LA CALIDAD DEL PRODUCTO SEA SUPERIOR Y QUE TENGA ESTABILIDAD DIMENSIONAL.
