Abstract
LA INVENCION SE REFIERE A UN FILTRO PARA MATERIAL TERMOPLASTICO, CON UNA CARCASA (1) EN LA QUE UN ELEMENTO (4) SOPORTE, EN PERFIL DE UN PISTON, PARA DOS NIDOS DE CRIBAS (8,9) ESTA MONTADO CON MOVIMIENTO LONGITUDINAL A LOS LARGO DE SU EJE. EN LA POSICION DE FILTRACION, LA COLADA FLUYE FUERA DEL CANAL (2) DE ALIMENTACION Y A TRAVES DE LOS CANALES DE ENTRADA (10-13) LLEGA A LOS ESPACIOS (14,15) DISTRIBUIDORES LOCALIZADOS EN LA PARTE FRONTAL DEL NIDO DE CRIBAS (8,9), DONDE A TRAVES DE LAS CRIBAS Y A TRAVES DE LOS CANALES (18,19) DE SALIDA LLEGAN AL CANAL (3) DE DESCARGA. CADA ESPACIO (14,15) DISTRIBUIDOR ESTA SUBDIVIDIDO EN SECCIONES POR AL MENOS UNA PARED (21), UN CANAL (10-13) DE ENTRADA ABRE HACIA AFUERA DENTRO DE CADA SECCION. MEDIANTE DESPLAZAMIENTO DEL ELEMENTO (4) SOPORTE DE FORMA LONGITUDINAL, PUEDE SER LLEVADO A DIFERENTES POSICIONES DE REFLUJO PARA CADA NIDO DE CRIBAS (8 O 9). EN ESTAS POSICIONES, TODOS LOS CANALES DE ENTRADA, CON LA EXCEPCION DE UNO QUE ESTA ASOCIADO CON EL NIDO DE LAS CRIBAS CORRESPONDIENTE AL REFLUJO, ESTAN CERRADOS, EL CANAL DE ENTRADA QUE ABRE ACTUA COMO CANAL DE RENOVACION PARA LA COLADA CIRCULANTE Y PARA LAS IMPUREZAS QUE TRANSPORTAN. ESTA COLADA DE ENJUAGUE ES ALIMENTADA, A TRAVES DEL CANAL (23) DE ENJUAGUE QUE DISCURRE DE FORMA COMPLETA DENTRO DEL ELEMENTO (4) SOPORTE, AL ESPACIO (16 O 17) COLECTOR DETRAS DEL NIDO DE LAS CRIBAS (8 O 9) DONDE ES ENJUAGADO.
