Abstract

EL INVENTO ES RELATIVO A UN DISPOSITIVO DE TRATAMIENTO POR MEDIO DE GAS DE UN BAÑO (2) LIQUIDO DE ALUMINIO MANTENIDO EN ESTADO ESTACIONARIO EN UN HORNO. ESTE DISPOSITIVO ESTA CONSTITUIDO POR UN PORTICO MOVIL COLOCADO POR ENCIMA DEL HORNO Y EN EL CUAL ESTAN SUSPENDIDOS AL MENOS TRES CONJUNTOS INYECTORES DE GAS (1) DE LONGITUD SUPERIOR A 2 METROS DE EJE DE SIMETRIA VERTICAL, ESTOS EJES TOMADOS DOS A DOS ESTAN SITUADOS EN PLANOS DIFERENTES, SUMERGIDOS EN PARTE EN EL BAÑO POR INTERMEDIO DE ABERTURAS (3) PRACTICADAS EN LA BOVEDA (4) DEL HORNO Y CUYAS PARTES SUMERGIDAS ESTAN SEPARADAS UNAS DE OTRAS UNICAMENTE POR EL BAÑO, DICHOS CONJUNTOS COMPRENDEN CADA UNO UN ARBOL (5) ROTATIVO PERFORADO SIGUIENDO SU EJE POR UNA CAVIDAD (6) CERRADA HACIA ABAJO Y DESEMBOCANDO POR ENCIMA DEL HORNO (7), DICHO ARBOL ESTA EQUIPADO EN SU PARTE SUPERIOR POR UN MOTOR (17) Y EN SU PARTE INFERIOR POR UN ROTOR (9) PROVISTO DE PALAS (10) PERFORADAS CADA UNA EN SU EXTREMO POR UN CANAL (11) UNIDO A LA CAVIDAD Y ESTA RODEADOPOR UN ESTATOR (13) QUE SE ALOJA HACIA ABAJO EN LA PROXIMIDAD DE LA CARA SUPERIOR DEL ROTOR Y HACIA ARRIBA POR ENCIMA DE LA BOVEDA DEL HORNO. ESTE DISPOSITIVO ENCUENTRA SU APLICACION EN EL TRATAMIENTO CON UNA GRAN EFICACIA, DE BAÑOS LIQUIDOS DE ALUMINIO, PRESENTANDO UNA SUPERFICIE LIBRE CONTINUA DE AIRE SUPERIOR A 10 M (AL CUADRADO) .
