Abstract

DISPOSITIVO PARA FABRICACION DE VIDRIO FUNDIDO. UN FUNDIDOR (10) RECIBE LOTES DE VIDRIO A FUNDIR Y LOS SUMINISTRA, A TRAVES DE UN REFINADOR (14), A UNOS CANALES DE ALIMENTACION (16, 18, 20) EN LOS QUE SE ENCUENTRAN UNOS ELLECTRODOS DE MOLIBDENO (22), CONECTADOS A UNA FUENTE DE CORRIENTE ALTERNA (24) POR MEDIO DE UNOS TRANSFORMADORES DE POTENCIA (26). PARA EVITAR LA FORMACION DE AMPOLLAS EN LOS ELECTODOS (22) SE DISPONE UNA FUENTE DE CORRIENTE CONTINUA (30), CON EL ELECTRODO NEGATIVO (32) EN EL FUNDIDOR (10) Y EL POSITIVO, A TRAVES DE UNOS FILTROS (28, 28A) EN EL CENTRO DE LOS SECUNDARIOS DE LOS TRANSFORMADORES (26).
