ao dass jeder einzelne Zweigkanal von dem Hauptkanal abgesperrt werden kann. Oberhalb jeder Haube und durch sie hindurclureichend ist ein Fülltrichter 26 angeordnet, um den betreffenden Herd mit der Beschickung zu füllen. Jeder Trichter ist mit einem Abschlussorgan versehen,
EMI2.1
geschlossen gehalten wird.
In der Einmündung des Kanals 20 in die Kammer 21 ist ein Ventilator 30 angeordnet.
Er ist nach Fig. l auf der Welle J7 befestigt, die am hinteren Ende in einem an den Querträgern 33 befestigten Lager 32 und am vorderen Ende in einem an der Vorderseite des Kanals 20 befestigten Lager 3 läuft. Das äussere Ende der Welle trägt eine Riemenscheibe 35 oder einen elektrischen Motor zum Antrieb des Ventilators. Durch diesen werden die Zinkdämpfe und Gase aus den Hauben abgesaugt und in die Ablagerungskammer getrieben und der erforderliche Luftzutritt

die quer von einer Seite der Kammer zur anderen laufen und abwechselnd geschrägte Lage haben. Die Rahmen bestehen aus beliebigem geeigneten Material, z.
B. rauhen Holzbrettern, oder aus mit Musselin überzogenen offenen Rahmen. Die Ablagerungskammer hat einen Auslass 37, welcher von den Abfängern zweckmässig durch eine Scheidewand 38 getrennt ist. In dem Auslass kann

Tür. 39 zur Ausleerung des niedergefallenen Zinkoxydes versehen.
Beim Betrieb der Vorrichtung wird zunächst ein Wagen in seiner erforderlichen Stellung unter die Hauben 79 gefahren und die nötigen elektrischen Anschlüsse werden vorgenommen. Da die Kohlenelektroden, wie erwähnt, durch eine Schicht gepulverter Holzkohle verbunden sind. wird beim Einschalten des elektrischen Stromes die Herdsohle sofort glühend. Die Beschickung kann dann unmittelbar auf einen solchen Herd gefüllt werden, wodurch die Wirkung der Voirichtung erhöht wird. Die Beschickung wird aus den Erzen oder sonstigen zinkhaltigen Materialien in zerstückeltem Zustand durch Mischen mit Flussmitteln, wie Salzkuchen oder Kochsalz, und zerfallenem Kalk oder borsaurem Kalk hergestellt.
Sie fällt aus dem Fülltrichter auf den Herd und kommt sofort mit einer grossen Fläche glühender Kohle in Berührung, so dass die Verdampfung des Zinks sofort beginnt. Die Verflüchtigung des Zinks kann je nach Art des benützten Materials

während die übrigen aus der Reduktion resultierenden Dämpfe und Gase aus der Oeffnung 37 aufgeblasen werden.
Es können auch mehr als zwei Herde auf jedem Wagen und entsprechende Hauben angeordnet werden, auch kann ein zweiter Schienenstrang und Herdwagen vor den auf der Zeichnung dargestellten gestellt werden, um einen vollständig ununterbrochenen Betrieb zu erzielen.

ao that each individual branch channel can be shut off from the main channel. A hopper 26 is arranged above each hood and extending through it in order to fill the relevant hearth with the load. Each funnel is provided with a closing element,

is kept closed.
A fan 30 is arranged at the confluence of the channel 20 into the chamber 21.
According to FIG. 1, it is fastened on the shaft J7, which runs at the rear end in a bearing 32 fastened to the cross members 33 and at the front end in a bearing 3 fastened to the front of the channel 20. The outer end of the shaft carries a pulley 35 or an electric motor to drive the fan. Through this, the zinc vapors and gases are sucked out of the hoods and driven into the deposition chamber and the required air access

which run transversely from one side of the chamber to the other and have alternating inclined positions. The frames are made of any suitable material, e.g.
B. rough wooden boards, or open frames covered with muslin. The deposition chamber has an outlet 37 which is suitably separated from the interceptors by a partition 38. In the outlet can

Door. 39 for emptying the fallen zinc oxide.
When operating the device, a carriage is first moved under the hoods 79 in its required position and the necessary electrical connections are made. Because the carbon electrodes, as mentioned, are connected by a layer of powdered charcoal. When the electric current is switched on, the hearth will immediately glow. The load can then be filled directly onto such a stove, whereby the effectiveness of the device is increased. The charge is made from the ores or other zinc-containing materials in a fragmented state by mixing them with fluxes such as salt cake or table salt, and disintegrated lime or boric acid lime.
It falls from the funnel onto the stove and immediately comes into contact with a large area of glowing coal, so that the zinc begins to evaporate immediately. The volatilization of the zinc can depend on the type of material used
EMI2.4
while the remaining vapors and gases resulting from the reduction are blown out of the opening 37.
More than two stoves and corresponding hoods can be arranged on each car, and a second track and bogie can be placed in front of the one shown in the drawing in order to achieve completely uninterrupted operation.
