Abstract
PROCEDIMIENTO Y DISPOSITIVO PARA LA PREPARACION DE PAPELOTE. EL PAPELOTE ES SUBDIVIDIDO MUY SUPERFICIALMENTE EN UN SOLUBILIZADOR DE PASTA, CON UNA CONSISTENCIA DE 8 A 12%, Y DISUELTO EN UNA TORRE DE ALMACENAMIENTO CON UNA CONSISTENCIA RELATIVA ENTRE 6 Y 7%. LA DISOLUCION EN EL SOLUBILIZADOR DE LA PASTA SE EFECTUA SOLAMENTE HASTA ALCANZAR LA BOMBEABILIDAD DE LA SUSPENSION. PREFERENTEMENTE, EN EL SOLUBILIZADOR DE LA PASTA SE TRABAJA CON UN ROTOR PROVISTO DE TORNILLOS SIN FIN DE IMPULSION, QUE NO GIRA EN PROXIMIDAD INMEDIATA DE UN TAMIZ Y QUE TAMPOCO ESTA PROVISTO DE ELEMENTOS DE FLUJO ADICIONALES A LAS HELICES DE IMPULSION. UN ESPACIO PARA PRODUCTO UTIL ESTA DISPUESTO LATERALMENTE EN EL SOLUBILIZADOR DE LA PASTA, DETRAS DE UN TAMIZ SUSTANCIALMENTE VERTICAL, ANTE EL QUE ESTA DISPUESTO MOVIL EN ROTACION UN RODETE CON ARBOL HORIZONTAL. SE CONSIGUE CON ELLO UNA ACTUACION PARTICULARMENTE CUIDADOSA DEL ROTOR DE DISOLUCION SOBRE EL CONTENIDO DEL SOLUBILIZADOR DE LA PASTA, DE MODO QUE LOS COMPONENTESDE SUCIEDAD O EXTRAÑOS (QUE NO SON PAPELOTE), COMO EN PARTICULAR LIGERAS PARTES Y LAMINAS DE PLASTICO, NO SON SUSTANCIALMENTE SUBDIVIDIDOS.
