Abstract

DISPOSITIVO DE CRIBADO A PRESION PARA PASTA PAPELERA. CONSTA DE UNA CARCASA CILINDRICA EN CUYO INTERIOR EXISTE UNA CRIBA, TAMBIEN CILINDRICA, DE FORMA QUE LOS EJES DE UNA Y OTRA (34, 36) ESTAN DESCENTRADOS PARA PRODUCIR UN AUMENTO DE SECCION EN LA ENTRADA DE LA PASTA A FILTRAR (42), PROVENIENTE DEL ALIMENTADOR (28). EXISTE UN TABIQUE SEPARADOR (40) Y UN DEFLECTOR (50) QUE DESCIENDE HELICOIDALMENTE ENTRE EL SEPARADOR Y EL ANILLO DE CRIBA, PARA CONDUCIR LA PASTA DE PAPEL. LA PASTA FILTRADA SALE POR EL INTERIOR, HACIA LA PARTE INFERIOR DEL DISPOSITIVO, RECOGIENDOSE EN EL COLECTOR (32). LA PASTA DESECHADA ES CONDUCIDA POR EL DEFLECTOR HACIA EL COLECTOR (30). EXISTEN DOS ENTRADAS DE FLUIDO (62, 64) PARA FACILITAR EL PROCESO. LA ENTRADA (62) SUMINISTRA LIQUIDO DE DILUCION, Y LA (64), LIQUIDO DE PURGA. HAY, ADEMAS, UNAS PALAS GIRATORIAS QUE EVITAN EL TAPONAMIENTO DE LA CRIBA.
