KAISERLICHESIMPERIAL
PATENTAMT,PATENT OFFICE,
Gegenstand vorliegender Erfindung ist ein elektrischer Ofen zur Gewinnung von Kupfer aus seinen Erzen, bei welchem in bekannter Weise mit einer elektrischen Reduktionskammer eine Reaktionskammer vereinigt ist. Bei diesem Ofen wird die in der Reaktionskammer sich bildende kupferreiche Schlacke zwecks Wiedergewinnung ihres Kupfers unter der Einwirkung der Strahlen des GebläsesThe present invention relates to an electric furnace for the extraction of copper from its ores, in which in a known manner with an electric reduction chamber a reaction chamber is combined. In this furnace, the copper-rich slag that forms in the reaction chamber becomes for the recovery of their copper under the action of the blower rays
ίο durch die Reduktionskammer getrieben.ίο driven through the reduction chamber.
Auf der beiliegenden Zeichnung ist die Erfindung veranschaulicht.The invention is illustrated in the accompanying drawing.
Fig. ι ist ein senkrechter Schnitt des Ofens.Fig. Ι is a vertical section of the furnace.
Fig. 2 ist ein wagerechter Schnitt nach der Linie A-B der Fig. I.Fig. 2 is a horizontal section along the line AB of Fig. I.
Fig. 3 zeigt eine Einzelheit einer der Elektroden. Figure 3 shows a detail of one of the electrodes.
Der Ofen besitzt eine Reduktionskammer a, mit der eine Reaktionskammer r unten durch einen Kanal c und in einiger Entfernung darüber durch eine Öffnung d in Verbindung steht. Im unteren Teil der Reduktionskammer α gehen die Elektroden / wagerecht durch die beiden Seitenwandungen des Ofens. Im allgemeinen sind die Elektroden hohl und werden innen von einem Wasserstrom durchlaufen, der, wie Fig. 3 zeigt, bei 1 eintritt und bei 2 austritt. In derselben Ebene wie die Elektroden münden in den Ofen die Luftdüsen g, welche von dem Verteilungsrohr h gespeist werden. Eine Öffnung i dient für den Ausfluß der auf dem Bad schwimmenden Schlacke.The furnace has a reduction chamber a, with which a reaction chamber r communicates at the bottom through a channel c and at some distance above through an opening d . In the lower part of the reduction chamber α the electrodes / go horizontally through the two side walls of the furnace. In general, the electrodes are hollow and are traversed internally by a stream of water which, as FIG. 3 shows, enters at 1 and exits at 2. In the same plane as the electrodes, the air nozzles g, which are fed from the distribution pipe h, open into the furnace. An opening i serves for the outflow of the slag floating on the bath.
Im Verhältnis wie das Erz unter der Einwirkung des elektrischen Stroms schmilzt, fließt es in die Reaktionskammer r, worin das gleichzeitige Einblasen eines Oxydationsmittels und eines Flußmittels durch bewegliche Düsen- auf bekannte Weise erfolgt. Dieser aus einem Gemisch von Luft und Dampf gebildete Strahl reißt die in dem Trichter k enthaltene Kieselsäure oder Kalk in Pulverform und event, pulverförmige Oxyde des in Behandlung befindlichen Metails und flüssige Kohlenwasserstoffe mit.As the ore melts under the action of the electric current, it flows into the reaction chamber r, in which the simultaneous injection of an oxidizing agent and a flux through movable nozzles takes place in a known manner. This jet, formed from a mixture of air and steam, entrains the powdered silica or lime contained in the funnel k and possibly powdered oxides of the material being treated and liquid hydrocarbons.
Die Oxydation und Verschlackung der aus dem Bad zu entfernenden Stoffe findet gleichzeitig statt, ohne die Ofenwandungen anzugreifen, und die entweichenden Gase werden gezwungen, durch die Öffnung d nach der Säule des frischen Erzes in der Reduktionskammer zu ziehen. Die durch die Strahlen der Düsen hervorgebrachten und von den Gasen mitgerissenen geschmolzenen Metallteilchen werden auf diese Weise durch das Erz zurückgehalten und nach dem unteren Teil der Reduktionskammer zurückgeführt, so daß jeder Verlust vermieden wird.The oxidation and slagging of the substances to be removed from the bath take place simultaneously without attacking the furnace walls, and the escaping gases are forced to pull through the opening d to the column of fresh ore in the reduction chamber. The molten metal particles brought out by the jets of the nozzles and carried away by the gases are thus retained by the ore and returned to the lower part of the reduction chamber, so that any loss is avoided.
Das bis zu dem gewünschten Grad gereinigte Kupfer wird durch die Öffnung / ausgelassen.The copper, cleaned to the desired degree, is passed through the opening / left out.
Zur Sicherheit ist ein Schornstein m vorgesehen, der durch eine Kappe geschlossen ist, welche man mit Hilfe einer Kette abheben kann. Der Schornstein ermöglicht, daß die Gase aus der Reaktionskammer un-For safety, a chimney m is provided, which is closed by a cap which can take off with the aid of a chain. The chimney allows the gases from the reaction chamber to
