Abstract

ESTA INVENCION DESCRIBE UN METODO Y UN APARATO PARA EL TRATAMIENTO DE PULPA, CUYO METODO Y APARATO SON ESPECIALMENTE APROPIADOS PARA TRATAR SUSPENSIONES DE FIBRA EN LA INDUSTRIA DEL PROCESADO DE LA MADERA. EL METODO Y EL APARATO ESTAN PARTICULARMENTE DISEÑADOS PARA ENGROSAR DICHAS SUSPENSIONES, EN OTRAS PALABRAS LIQUIDOS FILTRADOS DE SUSPENSIONES DE FIBRAS EN LA INDUSTRIA DE LA PULPA Y DEL PAPEL. LA INVENCION DESCRIBE CON MAS PRECISION UN CILINDRO LLAMADO CILINDRO DE TAMBOR, CUYA CONSTRUCCION BASICA COMPRENDE UN RECIPIENTE, EN EL CUAL SE SUMINISTRA LA SUSPENSION QUE ESTA SIENDO ENGROSADA Y UN CILINDRO CON UN CABLE EN SU SUPERFICIE ROTANDO EN EL RECIPIENTE. EL FILTRO DE TAMBOR, DE ACUERDO CON ESTA INVENCION SE CARACTERIZA EN QUE EL MIEMBRO DE CERRADO (40) DEL FILTRO DE TAMBOR TIENE UN CANAL (70) PARA LLEVAR EL GAS DESDE LOS TUBOS DE FILTRADO (24) A TRAVES DE LOS COMPARTIMENTOS DE LA CAMARA DE DISTRIBUCION (26) AL EXTERIOR DEL MIEMBRO DE CERRADO (40). EL METODO DE ACUERDO CON ESTA INVENCION SE CARACTERIZA EN QUE LA FASE DE FUNCIONAMIENTO DEL CILINDRO DE FILTRO SE DIVIDE EN CINCO FASES SEPARADAS UNA DE OTRA, EN LA PRIMERA FASE, DONDE EL CILINDRO DESCIENDE AL RECIPIENTE, EL AIRE Y EL FILTRADO INICIAL SON DESCARGADOS DESDE LOS COMPARTIMENTOS DE FILTRADO, Y EMPIEZA LA FORMACION DEL ROLLO DE PASTA EN LA SUPERFICIE DE CABLE; EN LA SEGUNDA FASE EL FILTRADO ES DESCARGADO CON VACIO Y LA FORMACION DEL ROLLO DE PASTA CONTINUA; EN LA TERCERA FASE EL ROLLO DE PASE ES SECADO POR MEDIO DE VACIO CUANDO DICHA PARTE DEL ROLLO HA SALIDO EN FORMA DE CILINDRO DEL RECIPIENTE; EN LA TERCERA FASE, LLAMADA DE EXTRACCION, EL ROLLO DE PASTA ES EXTRAIDO DE LA SUPERFICIE DE CABLE Y DESCARGADO DEL APARATO; Y EN LA TERCERA FASE, LLAMADA FASE DE LAVADO, SE LAVA LA SUPERFICIE DEL CABLE.
