Abstract
LA PRESENTE INVENCION SE REFIERE A UN METODO PARA TRATAR LA PULPA DE FIBRA RECICLADA, LAVANDO LAS IMPUREZAS COMO CENIZA, TINTA Y ADHERENTES DE LA MISMA. EL METODO SE CARACTERIZA POR LOS PASOS DE PULVERIZAR LA PULPA RECICLADA SOBRE UNA SUPERFICIE DE FILTRO, ELIMINANDO LAS IMPUREZAS A TRAVES DE DICHO FILTRO CON EL FILTRADO, PERMITIENDO LA FORMACION DE UNA TELILLA SOBRA LA SUPERFICIE DE FILTRO EN LA EXTRACCION DE LAS IMPUREZAS Y FILTRADO A TRAVES DE LA SUPERFICIE DE FILTRO, ROMPIENDO LA TELILLA, PERMITIENDO SU RECONSTRUCCION ELIMINANDO LAS IMPUREZAS Y FILTRADO A TRAVES DE LA SUPERFICIE DE FILTRO, Y DESECHAR LA PULPA RECICLADA DEL APARATO. ES TIPICO DEL APARATO, DE ACUERDO CON LA INVENCION, QUE SE PROPORCIONA AL MENOS UN MECANISMO (16) PARA EL SUMINISTRO DE PULPA RECICLADA SOBRE UNA SUPERFICIE DE FILTRO, ESTANDO DICHO MECANISMO DISPUESTO POR ENCIMA DE UN PLANO HORIZONTAL QUE PASA A LO LARGO DEL EJE DEL CILINDRO (10).
