Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO PARA BLOQUEO DE UNA COLADA, EN PARTICULAR DE PLASTICO, QUE FLUYE EN UNA CONDUCCION DE COLADA. EL DISPOSITIVO MUESTRA UNA ZONA DE ENFRIAMIENTO QUE RECORRE LA COLADA, EN DONDE SE DISPONE DE CONDUCCIONES (12) DE REFRIGERACION QUE GUIAN EL MEDIO REFRIGERANTE CON UNA DISTANCIA TRANSVERSAL CON RESPECTO A LA CORRIENTE DE COLADA Y UN EQUIPAMIENTO DE TAL TIPO, QUE EN EL ENFRIAMIENTO DE LA COLADA SE FORMAN PUENTES (14,15) FIJOS ENTRE LAS CONDUCCIONES (12) DE ENFRIAMIENTO Y LOS PUENTES (14,15) CON LAS CONDUCCIONES (12) DE ENFRIAMIENTO FORMAN UNA ZONA DE BLOQUEO QUE SE DISPONE DE FORMA TRANSVERSAL COMPLETA CON RESPECTO A LA CORRIENTE DE COLADA.
