Abstract

EN UN APARATO DE FILTRO PARA AGUA CIRCULANTE SE HA PREVISTO UN DISPOSITIVO PARA UN ENJUAGADO REPETITIVO, QUE CONTIENE UN ELEMENTO (18) DE ENJUAGADO PREVISTO CON AL MENOS UNA ABERTURA (44) DE ENTRADA EN FORMA DE RANURA, QUE PUEDE SER UNIDA EN EL LADO DE SALIDA CON UN CANAL DE ENJUAGADO. EL ELEMENTO (18) DE ENJUAGADO SE ENCUENTRA DENTRO DE UN ELEMENTO (16) DE FILTRO DISPUESTO AXIALMENTE DE FORMA DESPLAZABLE. LA ABERTURA (44) DE ENTRADA EN FORMA DE RANURA QUE SE MUESTRA DE MODO ESENCIALMENTE RADIAL CONTRA LA SUPERFICIE INTERIOR DEL ELEMENTO (16) DE FILTRO SE EXTIENDE SOBRE LA SUPERFICIE DE FILTRADO COMPLETA DEL LADO DE AGUA PRIMARIA EN UN DESPLAZAMIENTO AXIAL DEL ELEMENTO (18) DE ENJUAGADO, DE FORMA QUE EL ELEMENTO (16) DE FILTRO SE LIMPIA SUCESIVAMENTE A TRAVES DE SU ALTURA COMPLETA A PARTIR DE LA CAMARA (28) DE AGUA DE LIMPIEZA QUE CIRCULA A TRAVES DE ESTE ELEMENTO (16) DE FILTRO HACIA EL ELEMENTO DE ENJUAGADO. EL ELEMENTO DE ENJUAGADO MUESTRA UN EMBOLO (66) DE ETAPAS, QUE SE IMPULSA CON LAAYUDA DE UN EQUIPO DE CONTROL ACCIONABLE DE FORMA MANUAL AUTOMATICA CON PRESIONES DIFERENTES A ELECCION, ACCIONANDO UN DESPLAZAMIENTO AXIAL AUTOMATICO DEL ELEMENTO (18) DE ENJUAGADO ENTRE AMBAS POSICIONES EXTREMAS.
