Description
Hohle Elektrode zum Betriebe elektrischer Öfen Elektrische Öfen, bei denen die Charge durch eine hohle Elektrode zugeführt und die im Ofen gebildeten Gase im Gegenstrom zur Chargenrichtung durch den Hohlraum der Elektrode abgeführt werden, sind bekannt. Es ist ferner bekannt, im Inneren einer Elektrode ein gegen diese isoliert angeordnetes Rohr vorzusehen, durch welches die Charge dem Ofen zugebracht wird. Auch ist vorgeschlagen worden, das Tauchrohr im Kanal der Elektrode beweglich anzuordnen. Die Erfindung ist bestimmt, Nachteile dieser bekannten Einrichtungen zu beseitigen. Zu diesem Zweck ist das Zuführungsrohr bzw. sein Chargierende teleskopartig ausgebildet. Diese Ausbildung ermöglicht es, das Schmelzgut durch die auf dem Ofenherd aufsitzende Beschickungssäule unter einem gewissen Druck zu halten, wodurch die Verdampfung der Ofenprodukte verhindert wird.Hollow electrode for operating electric ovens. Electric ovens to which the charge is fed through a hollow electrode and those formed in the furnace Gases discharged in countercurrent to the batch direction through the cavity of the electrode are known. It is also known to have a counter inside an electrode to provide this insulated pipe through which the charge is brought to the furnace will. It has also been proposed that the immersion tube be movable in the channel of the electrode to arrange. The invention is intended to address disadvantages of these known devices to eliminate. For this purpose, the feed pipe or its charging end is telescopic educated. This training makes it possible for the melted material to pass through on the furnace hearth to keep the loading column mounted under a certain pressure, thereby reducing the Evaporation of the oven products is prevented.
Ein gemäß der Erfindung ausgestatteter Ofen ist in den beigefügten Abbildungen beispielsweise dargestellt.An oven equipped in accordance with the invention is shown in the attached drawings Illustrations shown for example.
Der Ofen a ist durch ein Gewölbe b abgedeckt. Die Elektrode wird durch dieses Gewölbe vermittels einer Stopfbüchse c oder einer sonst geeigneten Abdichtung in den Ofen eingeführt.The furnace a is covered by a vault b . The electrode is introduced into the furnace through this vault by means of a stuffing box c or some other suitable seal.
Die Zuführung der Beschickung erfolgt durch den Hohlraum e der Elektrode d, und zwar vermittels eines Beschickungszuführungsrohres f, das in der hohlen Elektrode in bekannter Weise angeordnet ist. . Die Stromzuführung zur Elektrode bleibt die gleiche, wie sie allgemein in solchen Fällen üblich ist. Natürlich kann die Elektrode auch praktisch endlos arbeitend gemacht werden bzw. können auch ungebrannte Elektroden bekannter Art verwendet werden.The feed is fed through the cavity e of the electrode d, specifically by means of a feed feed pipe f which is arranged in the hollow electrode in a known manner. . The power supply to the electrode remains the same as is generally the case in such cases. Of course, the electrode can also be made to work practically endlessly, or unfired electrodes of a known type can also be used.
Das in die Elektrode bis fast zu ihrem unteren Ende hineinragende Beschickungsrohr f besitzt oben ein teleskopartig ausgebildetes Endstück t, das sich beim Ansetzen neuer Elektroden (Abb. 2) zusammenschieben läßt.The one that protrudes into the electrode almost to its lower end Feed pipe f has a telescopic end t at the top, which can be pushed together when attaching new electrodes (Fig. 2).
Im übrigen ist das Beschickungsrohr mit der Vorschubreguliereinrichtung der Elektrode verbunden, so daß es die Bewegungen der Elektrode mitmacht.In addition, the feed pipe is connected to the feed regulator connected to the electrode so that it follows the movements of the electrode.
Von einem über dem Beschickungsrohr befindlichen Bunker g, der seinerseits durch eine geeignete Füllvorrichtung beschickt wird, fällt die Charge durch das Zuführungsrohr und die Elektrode in den Ofen.From a bunker g located above the feed pipe, which in turn is charged by a suitable filling device, the batch falls through the Feed tube and the electrode in the furnace.
Unterhalb des Bunkers ist ein Gasabsaugerohr o angebracht, durch welches die Ofengase im Gegenstrom zur Beschickungseinrichtung aus den Ofen abgesaugt werden.A gas suction pipe o is attached below the bunker, through which the furnace gases are sucked out of the furnace in countercurrent to the charging device.
