Abstract

Unos perfeccionamientos en los sistemas de refrigeración de líneas de extrusión, constituidos por circuitos perfectamente separados, uno aplicable a las desgasificadoras y consiste en un conducto común de recoda de las aguas que las envía a un pozo, del cual son extraídas por una bomba hacia la torre de refrigeración, siendo recogidas posteriormente en un pozo y devueltas a los desgasificadores para seguir realizando su refrigeración, mientras que la línea de refrigeración de las extrusoras está constituida también por un conducto común de recogida del agua caliente que a través de un sistema de bombas y filtros es enviada a un depósito, del que pasa a una torre de refrigeración y, después transportada a un depósito nodriza, que alimenta a tantos depósitos como extrusoras existen, previéndose la existencia de filtros de arena para la limpieza del agua y su posterior reenvío a cada extrusora.Improvements in the cooling systems of extrusion lines, consisting of perfectly separate circuits, one applicable to degassing machines and consists of a common duct for the backwatering of the water that sends them to a well, from which they are extracted by a pump to the cooling tower, being subsequently collected in a well and returned to degassers to continue cooling, while the extruder's cooling line is also constituted by a common hot water collection line that through a pump system and filters are sent to a tank, from which it passes to a cooling tower and, then transported to a nurse tank, which feeds as many tanks as extruders exist, providing for the existence of sand filters for water cleaning and subsequent forwarding to each extruder.
