Abstract

APARATO DE CRIBADO A PRESION PARA CRIBAR PASTA DE FIBRA DE PAPEL. CONSTA DE UNA CAJA PRINCIPAL SITUADA SOBRE UNA BASE DE APOYO; DE UN ELEMENTO DE CRIBADO CILINDRICO PROVISTO DE MULTIPLES AGUJEROS CIRCULARES QUE DIVIDE EL INTERIOR DE LA CAJA PRINCIPAL EN UNA CAMARA CENTRAL DE ALIMENTACION CON UN ACCESO DE ENTRADA PARA EL MATERIAL Y UNA CAMARA DE MATERIAL ACEPTADO QUE TIENE UN ACCESO DE SALIDA; DE UN ELEMENTO ROTATORIO PROVISTO DE PALETAS MOVILES CURVADAS EN SENTIDO HELICOIDAL, QUE ESTA SITUADO EN LA CAMARA DE ALIMENTACON; DE UNA PLURALIDAD DE CAVIDADES POCO PROFUNDAS FORMADAS POR UN CONJUNTO DE BARRAS DE SECCION CUADRADA, SITUADAS EN EL LADO DE ENTRADA DEL CILINDRO DE CRIBADO, Y DE UN MECANISMO QUE ACCIONA EL ELEMENTO ROTATORIO PARA QUE LAS PALETAS CREEN UNA TURBULENCIA EN LA PASTA.
