Abstract

ESTE INVENTO ES UN APARATO MEJORADO PARA LA PRODUCCION DE POLVO METALICO MEDIANTE UN METODO DE ATOMIZACION POR GAS. EL APARATO COMPRENDE UN RECIPIENTE QUE CONTIENE EL METAL FUNDIDO (1) DE FORMA CILINDRICA EN LA PARTE INFERIOR, UN CANAL DE DESCARGA DEL METAL FUNDIDO (2) INSTALADO EN LA PARTE INFERIOR DEL RECIPIENTE, Y UN DISPOSITIVO DE PULVERIZACION DEL METAL FUNDIDO (4), QUE TIENE BOQUILLAS DE IMPULSION DE GAS (42) EN UNA CAMARA DE PULVERIZACION (41) CONECTADA AL EXTREMO INFERIOR DEL CANAL; SE CARACTERIZA PORQUE EL APARATO LLEVA UNA BOBINA DE CALENTAMIENTO POR INDUCCION (6) DE UN DIAMETRO MENOR, O SEGUNDA BOBINA DE CALENTAMIENTO POR INDUCCION QUE RODEA AL CANAL, ADEMAS DE UNA BOBINA DE CALENTAMIENTO POR INDUCCION (5) DE UN DIAMETRO MAYOR, O PRIMERA BOBINA DE CALENTAMIENTO POR INDUCCION QUE RODEA AL RECIPIENTE (1); SE CARACTERIZA ASIMISMO PORQUE LA PARTE DE LA BOQUILLA DEL CANAL (2) ES UNA PUERTA DESLIZANTE (6) REALIZADA EN CERAMICA; PORQUE UNA PLACA DE PROTECCION MAGNETICA Y CON FORMA DE ANILLO (27) HECHA DE UN MATERIAL NO MAGNETICO Y CONDUCTOR ELECTRICO SE ENCUENTRA ENTRE LA BOBINA DE CALENTAMIENTO POR INDUCCION (5) DE MENOR DIAMETRO Y LA COMPUERTA DESLIZANTE (6); Y PORQUE LA PLACA DE PROTECCION VA EQUIPADA CON UN MEDIO DE ENFRIAMIENTO. LA PLACA DE PROTECCION MAGNETICA (7) ES PREFERIBLEMENTE UN CUERPO HUECO Y REFRIGERADO POR AGUA FRIA QUE PASA A TRAVES DEL MISMO. LA ATOMIZACION PUEDE COMENZAR Y TERMINAR INSTANTANEAMENTE EN CUALQUIER MOMENTO. EL FLUJO PROCEDENTE DE LA BOBINA DE CALENTAMIENTO NO SE EXTIENDE HASTA LA COMPUERTA DESLIZANTE DEL CANAL DE DESCARGA, Y LA COMPUERTA DESLIZANTE NO SE CALENTARA Y NO SE PRODUCIRA NINGUNA PERDIDA DE FLUJO EN SU INTERIOR. COMO REALIZACION PREFERIDA, SE UTILIZA EL RECIPIENTE QUE CONTIENE EL METAL FUNDIDO, QUE COMPRENDE UN CUERPO HECHO DE MATERIALES REFRACTARIOS DE REVESTIMIENTO EN LA PARED INTERIOR DE UNA CAPA DE MATERIAL IMPERMEABLE A LOS GASES Y NO CONDUCTOR ELECTRICO, Y UNA TAPADERA QUE PUEDE IR ESTRECHAMENTE UNIDA AL CUERPO.UN MEDIO GENERADOR DE VACIO SE CONECTA A LA TAPADERA. ESTE APARATO PROPORCIONA METAL EN POLVO LIMPIO SIN CONTAMINACION POR EL OXIGENO DEL AIRE.
