Abstract

SE DESCRIBE UN EXTRUSOR PARA FUNDIR UN GRANULADO DE PLASTICO, QUE SE HA CONFORMADO EN UNA UNIDAD CONSTRUCTIVA INTEGRADA, EN DOS ETAPAS, CON UNA ETAPA DE EXTRUSION (1) QUE MUESTRA UNA ROSCA DE EXTRUSION (3) EN UN CILINDRO CALEFACTABLE (5) ASI COMO UNA ETAPA DE SECADO (23) QUE POSEE UNA ROSCA DE TRANSPORTE CALEFACTABLE (4) CON UNOS ELEMENTOS DE DESPLAZAMIENTO (24), QUE SECAN EL GRANULADO DE PLASTICO Y LO TRANSPORTAN SIN COMPRESION. CONFORME A LA INVENCION SE HA DISPUESTO LA ROSCA DE TRANSPORTE (4) EN UNA CAMARA DE SECADO (2) Y SE HA CONFIGURADO, RESPECTO A LA ROSCA DE EXTRUSION (3), CON UN DIAMETRO MAYOR Y UN ELEMENTO DE DESPLAZAMIENTO (24) CON UNA HENDIDURA MAYOR.
