Abstract

LA INVENCIÓN SE REFIERE A UN DISPOSITIVO PARA LA OBTENCIÓN DE METALES O COMPOSICIÓN DE METALES DESDE UN MATERIAL QUE CONTIENE EL METAL O LA COMPOSICIÓN DE METALES, CON EL FIN DE INTEGRAR LA PURIFICACIÓN DE ESCORIAS Y AUMENTAR LA EFICIENCIA MEDIANTE UNA SOLA ETAPA, UN SOLO EQUIPO Y CON UNA MANIPULACIÓN MÁS SIMPLE, CON UNA CUBA DE HORNO (2) CON UN PRIMER INGRESO PARA LA ENTRADA DEL MATERIAL Y UNA PRIMERA SALIDA (10) PARA LA EXTRACCIÓN DE GAS DE ESCAPE, CON VARIOS ELECTRODOS (1) PARA LA FUSIÓN DEL MATERIAL SUMINISTRADO. LOS QUE SE INTRODUCEN EN LA CUBA DEL HORNO, CON UN ELECTRODO DE FONDO (5) QUE CONFORMA UN CÁTODO, QUE COMPRENDE UN ESPACIO (16) EN EL ÁREA DE DESCARGA DE ESCORIA (12) QUE SIRVE COMO ZONA DE DECANTACIÓN; UN ELECTROIMÁN O IMÁN PERMANENTE (6) QUE ESTÁ COLOCADO DE TAL FORMA EN LA CUBA DEL HORNO QUE SU CAMPO MAGNÉTICO SEA TRASPASADO POR EL FLUJO DE CORRIENTE CONTINUA (DC) DE MODO QUE POR MEDIO DE LA SUPERPOSICIÓN DE LOS CAMPOS MAGNÉTICOS Y ELÉCTRICOS RESULTEN FUERZAS COMBINADAS CUYO EFECTO ES UNA ACCIÓN DE MEZCLA Y AGITACIÓN DEL MEDIO QUE SE ENCUENTRA DENTRO DEL HORNO; Y UNE DESCARGA (8) PARA LA EXTRACCIÓN DEL METAL FUNDIDO O LA COMPOSICIÓN DE METALES Y UN REBALSE O DESCARGA (12) PARA LA ESCORIA.THE INVENTION REFERS TO A DEVICE FOR OBTAINING METALS OR METAL COMPOSITION FROM A MATERIAL CONTAINING THE METAL OR THE METAL COMPOSITION, IN ORDER TO INTEGRATE THE PURIFICATION OF SLABS AND INCREASE EFFICIENCY THROUGH A SINGLE STAGE, A SINGLE STAGE AND WITH A SIMPLE HANDLING, WITH A FURNACE TUB (2) WITH A FIRST INPUT FOR THE MATERIAL INPUT AND A FIRST OUTPUT (10) FOR THE EXHAUST GAS EXTRACTION, WITH SEVERAL ELECTRODES (1) FOR THE MATERIAL FUSION SUPPLIED. THOSE THAT ARE INTRODUCED INTO THE OVEN TANK, WITH A BOTTOM ELECTRODE (5) THAT MAKES UP A CATHODE, INCLUDING A SPACE (16) IN THE SLAUGH DISCHARGE AREA (12) THAT SERVES AS A DECANTATION AREA; A PERMANENT ELECTROMAGNET OR MAGNET (6) THAT IS PLACED IN SUCH A WAY IN THE OVEN TUBA THAT ITS MAGNETIC FIELD IS TRANSFERRED BY THE FLOW OF DIRECT CURRENT (DC) SO THAT THROUGH THE SUPERPOSITION OF THE MAGNETIC AND ELECTRICAL RESULTING FIELDS COMBINED WHOSE EFFECT IS AN ACTION OF MIXING AND AGITATION OF THE ENVIRONMENT WHICH IS LOCATED IN THE OVEN; AND JOINS DISCHARGE (8) FOR THE EXTRACTION OF THE MELTED METAL OR THE COMPOSITION OF METALS AND AN OVERFLOW OR DISCHARGE (12) FOR THE SLAG.
