Abstract

UN APARATO DEPURADOR (10) COMPRENDE UN PAR DE CRIBAS CONCENTRICAS FIJAS (26 Y 32) CON UNA PLURALIDAD DE ESTRUCTURAS DE LAMINA (42) GIRANDO ENTRE ELLAS Y ADYACENTES ARESTAS, ESTANDO RADIALMENTE ALINEADAS UNAS LAMINAS INDIVIDUALES (44 Y 46) DE CADA ESTRUCTURA DE LAMINA. EL APARATO DEPURADOR COMPRENDE UNA ENTRADA DE LECHADA TANGENCIALMENTE DISPUESTA (20) Y UNA SALIDA DE REJECCION FUERTE TANGENCIAL Y DIAMETRALMENTE DISPUESTA (22) EN EL EXTREMO DE UN SIFON DE RECHAZO FUERTE. EL RECHAZO FLOJO ACEPTA FLUJOS DE LECHADA EN LA ZONA DE CRIBADO Y, DESPUES DE LA SEPARACION, SE DESCARGA EN UN EXTREMO DEL APARATO DEPURADOR POR MEDIO DE RESPECTIVOS RECHAZADORES LIGEROS (58, 60, 60") Y ACEPTA (16) SALIDAS. LA SALIDA DE ACEPCION ESTA LOCALIZADA AXIALMENTE RESPECTO A LOS CILINDROS DE LA CRIBA Y LAMINAS ROTATORIAS DE TAL FORMA QUE LOS IMPULSOS DE PRESION SON VIRTUALMENTE ELIMINADOS EN EL PROCESO DE DEPURACION. EL APARATO SE PUEDE CONSTRUIR PARA LA ROTACION VERTICAL U HORIZONTAL DE LAS LAMINAS.
