Description
Aufgabevorrichtung für metallurgische Öfen. Die neuartige Aufgabevorrichtung soll Anwendung finden an Ofen, deren Betrieb es fordert, daß die Aufgabe des Durchsatzes dem Ofengang angepaßt in gleichen Zeitabständen erfolgen muß, ohne daß dabei eine Störung der Verbrennung durch Eintreten falscher Luftmengen oder eine Belästigung der Umgebung durch Austreten schädlicher Gasmengen eintreten darf. Bei besonderen Ofenarten, wie z. B. zum Rösten von Schwefelkies, wird der Ofengang bzw. Abbrand infolge unregelmäßiger Aufgabe sowie Eintretens falscher Luft und Austretens von Gas empfindlich gestört, womit gleichzeitig auch Verluste verbunden sind. Diese Nachteile werden mit der neuartigen Aufgabevorrichtung aufgehoben.Feeding device for metallurgical furnaces. The new feeding device is intended to be used in furnaces, the operation of which requires that the throughput be given up must be adapted to the furnace cycle at the same time intervals, without a Disturbance of the combustion due to the ingress of incorrect amounts of air or a nuisance the environment through the escape of harmful gas quantities. With special Furnace types, such as B. for roasting pebbles, the furnace gear or burn-off as a result of irregular discharge as well as incorrect air entering and leakage of Gas sensitively disturbed, which at the same time also involves losses. These Disadvantages are eliminated with the new feeding device.
Die Zeichnung zeigt mit Abb. z und 2 deren beispielsweise Anordnung an einen Ofen zum Rösten von Schwefelkies, während Abb. 3 die Aufgabekammer selbst zeigt. Letztere ist einer bekannten Art nachgebildet und besteht in der gezeichneten Form aus einem Schacht a, welcher an der unteren Seite von einem Konus b an einer beweglichen Aufhängung c abgeschlossen ist. Mittels der Achse d, des Gegenhebels e und des Gewichts f wird das Offnen und Schließen der Kammern a durch Heben und Senken des Konus b bewirkt. :Nach Abb. i und 2 erfolgt dieses durch einen über die Ofendecke g umlaufenden Arm h mit Zapfen i. An diesem Arm la befindet sich ferner ein Zubringer k, welcher die Kammer a füllt und auf eine bestimmte Durchgangsmenge abstreicht. Der Durchsatz des Ofens ist abhängig von der Anzahl der in den Ofen gelangenden Kammerfüllungen, welche durch Einsätze l auf :ein bestimmtes Maß gehalten werden.The drawing shows with Fig. Z and 2 their arrangement, for example, on a furnace for roasting pyrites, while Fig. 3 shows the feed chamber itself. The latter is modeled on a known type and consists in the form shown of a shaft a, which is closed on the lower side by a cone b on a movable suspension c. By means of the axis d, the counter lever e and the weight f , the chambers a are opened and closed by raising and lowering the cone b. : According to Fig. I and 2, this is done by an arm h with peg i running around the furnace roof g. On this arm la there is also a feeder k, which fills the chamber a and sweeps over a certain amount of passage. The throughput of the furnace depends on the number of chamber fillings that enter the furnace, which are kept to a certain level by inserts l.
.Von wesentlicher Eigenart ist bei dieser Aufgabevorrichtung, daß die Kammer a sogleich nach dem Entleeren wieder mit Durchsatzmaterial gefüllt ist, womit bei dem ungenügenden Abschluß des Konus b,der Durchgang von Luft und Gas unterbunden ist. Dies wird bewirkt, indem der Zapfen i durch Drehen des Gegenhebels e den Konus b senkt und das Gegengewicht f diesen wieder hebt, worauf der Zubringer k die Kammer a füllt und abstreicht. Die Kammer a bleibt somit bis zu ihrer nächsten Entleerung mit Durchsatzmaterial gefüllt, und wiederholt sich dieser Vorgang dem Ofengang angepaßt in bestimmten Zeitabständen, die entweder durch einen beweglichen Ofenteil oder einen besonderen Mechanismus zwangläufig eingehalten werden.An essential peculiarity of this feeding device is that the chamber a is filled again with throughput material immediately after emptying, so that the passage of air and gas is prevented if the cone b is insufficiently closed. This is achieved in that the pin i lowers the cone b by turning the counter-lever e and the counterweight f raises it again, whereupon the feeder k fills the chamber a and wipes it off. The chamber a thus remains filled with throughput material until it is next emptied, and this process is repeated at certain time intervals, adapted to the course of the furnace, which are inevitably maintained either by a movable furnace part or a special mechanism.
