Gegenstand der Erfindung ist eine neue Vorrichtung an mechanischen Röstofen mit übereinander liegenden Herden und abwechselnd in der Mitte und am Umfang dieser, Herde angeordneten Durchtrittsöffnungen für das Erz und die Gase, durch welche die Bildung von Flugstaub unter Anwendung kreisender, die Fallstellen des Erzes überdeckender Schirme verhütet werden soll.The invention relates to a new device with mechanical roasting oven herds lying one above the other and alternately in the middle and on the periphery of these, Hearth arranged through openings for the ore and the gases through which the formation of fly dust with the use of circling, covering the fall points of the ore Umbrellas should be prevented.
ίο Eine Einrichtung dieser Art ist zwar bekannt. Bei dieser bilden die auf den Rührarmen befestigten Schirme allseitiggeschlossene Fallräume für das Erz, indem sie nahe bis an die beiden Herde heranreichen und sich mit ihren entsprechend abgebogenen Enden an die Ofenwand anschließen. Bei dieser Einrichtung bietet aber die Abdichtung der kreisenden Schirme gegenüber dem darüber ■befindlichen Ofengewölbe große Schwierigkeit und es dringen fast immer Gase über die Schirme hinweg in den Falhjaum, dies ganz besonders, da die Gase sich naturgemäß in den einzelnen Ofenräumen an dem Gewölbe entlang bewegen.ίο An institution of this type is known. In this case, the screens attached to the agitator arms are closed on all sides Trap spaces for the ore by reaching close to the two herds and each other with their bent ends to the furnace wall. At this However, the facility offers the sealing of the circling screens from the one above ■ the furnace vault is very difficult and gases almost always penetrate through the Umbrellas into the Falhjaum, especially since the gases are naturally in move the individual furnace chambers along the vault.
Um nun diesen Übelstand zu beseitigen, sind nach vorliegender Erfindung die Schirme nach einem einfachen Kreise gekrümmt, d. h. sie lassen den Fallraum an den Enden offen und lehnen sich mit ihrem oberen Rande gegen einen am Ofengewölbe vorgesehenen, nach unten ragenden ringförmigen Ansatz und werden gegen diesen beispielsweise unter Einwirkung geeignet an ihnen angeordneter Gegengewichte fest angedrückt. Hierdurch wird eine stete Selbstabdichtung zwischen dem Ofengewölbe und den Schirmen erzielt, so daß ein Eindringen der aufsteigenden Gase über die Schirme hinweg in den jeweiligen Fallraum des Erzes ausgeschlossen ist und damit eine Flugstaubbildung mit Sicherheit vermieden wird, wenn die Schirme genügend breit gewählt werden.In order to eliminate this drawback, the screens are according to the present invention curved to a simple circle, d. H. they leave the fall space open at the ends and lean with their upper edge against a downwardly projecting annular projection provided on the furnace vault and are appropriately arranged on them against this, for example, under the influence Counterweights pressed down firmly. This creates a constant self-seal between the furnace vault and the screens, so that penetration of the rising gases is excluded over the screens in the respective drop space of the ore and so that the formation of airborne dust is avoided with certainty if the umbrellas are sufficient can be chosen broadly.

Auf der Zeichnung sind 1 die übereinander 50' liegenden Herde, auf denen das Röstgut mittels eines geeigneten Rührwerks abwechselnd, auf dem einen vom Umfang nach der Mitte, auf dem nächsten umgekehrt von der Mitte nach dem Umfang gefördert wird, wo Durchtrittsöffnungen 2 bezw. 3 zur Überführung des Gutes auf den nächst unteren Herd vorgesehen sind, die zugleich dem Aufstieg der Gase dienen. Das Rührwerk besteht aus der lotrecht stehenden, entsprechend angetriebenenOn the drawing there are 1 on top of each other 50 ' lying stoves, on which the roasted food is alternated using a suitable agitator, on one from the circumference to the middle, on the next the other way around from the middle is promoted to the extent where passage openings 2 BEZW. 3 for overpass of the goods on the next lower stove are provided, which at the same time the rise of the Serve gases.
