Abstract
SE PRESENTA UN APARATO FILTRADOR QUE INCLUYE DOS O MAS CONDUCTOS (2) QUE ACTUAN EN PARALELO, CADA UNO DE LOS CUALES TIENEN UN FILTRO EXTENDIDO (12) QUE PASA A TRAVES DE UNOS PUERTOS DE ENTRADA Y SALIDA (48, 49), PREFERIBLEMENTE SELLADOS POR TAPONES SOLIDIFICADOS DE LA SUBSTANCIA FLUIBLE TAL COMO UN POLIMERO QUE ESTA SIENDO FILTRADO. EL FLUJO DE DICHA SUBSTANCIA HASTA UNO DE LOS CONDUCTOS PUEDE FINALIZARSE DE MANERA QUE SE PERMITA EL AVANCE DEL FILTRO BAJO CONDICIONES DE CAIDA ABSOLUTA DE PRESION, MIENTRAS QUE EL FLUJO A TRAVES DEL OTRO CONDUCTO CONTINUA. EL AVANCE DEL FILTRO PUEDE ESTAR AYUDADO POR LA EXTRUSION DE UN TAPON SELLADOR EN EL PUERTO DE SALIDA BAJO LA PRESION DE DICHA SUBSTANCIA DESDE EL OTRO CONDUCTO QUE ESTA FILTRANDO AUN. EN UN MODO ADICIONAL O ALTERNATIVO, EL FLUJO EN EL INTERIOR DEL CONDUCTO FINALIZA Y SE ABRE UNA SALIDA SECUNDARIA (20, 21) EN ESE CONDUCTO. ESTO CREA UN FLUJO INVERSO BAJO LA PRESION DE LA SUSTANCIA DEL OTRO CONDUCTO, QUE LIMPIARA EL FILTRO. LA SALIDA SECUNDARIA PUEDE SELLARSE MEDIANTE UN TAPON QUE SE EXTRUDE MEDIANTE EL FLUJO INVERSO. UNA VALVULA ALTERNATIVA PARA LA SALIDA SECUNDARIA, QUE TAMBIEN PUEDE USARSE EN UNA VALVULA SEPARADORA PARA CONTROLAR LA ENTRADA DE SUBSTANCIA A LOS DOS CONDUCTOS, TIENE UN CONDUCTO LATERAL (26) EN EL CUAL SE FORMA UN TAPON DE SUBSTANCIA SOLIDIFICADA, Y MEDIOS (27) PARA EMPUJAR EL TAPON AL INTERIOR DE LA SUSTANCIA DEL FLUJO.
