KLASSE 40 a. CLASS 40 a.
Patentirt im Deutschen Reiche vom 26. April 1899 ab.Patented in the German Empire on April 26, 1899.
Die vorliegende Erfindung bezieht sich auf einen neuen Röstapparat, der zuni Rösten von Erzen, namentlich von . Schwefelerzen dient, und verfolgt den Zweck, das Stauen des Röstgutes in den Retorten unmöglich zu machen.The present invention relates to a new roaster used for roasting Ores, in particular of. Sulfur ores is used and has the purpose of stowing the roasted material impossible to do in the retorts.
Die einzelnen Retorten sind bei vorliegender Construction über einander gelagert, und der erstrebte Zweck wird dadurch erreicht, dafs die Geschwindigkeit der Förderschnecken in den einzelnen Retorten nach unten zunimmt.In the present construction, the individual retorts are stacked on top of one another, and the The intended purpose is achieved by increasing the speed of the screw conveyors the individual retorts increases downwards.
Der Apparat ist auf beiliegender Zeichnung dargestellt.The device is shown in the accompanying drawing.
Fig. ι ist ein Längsschnitt durch denselben, Fig. "2 ein Schnitt durch die Mitte.Fig. 1 is a longitudinal section through the same, Fig. "2 is a section through the center.
Der Apparat besteht aus Seitenwandungen 2, Vorder- und Hinterwandungen 1, oberem Gewölbe 3 und einem geeigneten Roste 4. In dem oberen Gewölbe befindet sich eine Ableitung 5, die zu einem Schornstein oder Waschapparate führt, und welche die während des Röstprocesses in dem Ofen entwickelten Gase in bekannter Weise zur weiteren Nutzbarmachung ableitet.The apparatus consists of side walls 2, front and rear walls 1, upper vault 3 and a suitable grate 4. In the upper vault there is a drainage 5, which leads to a chimney or washing apparatus, and which the during During the roasting process in the oven, gases evolved in a known manner for further utilization derives.
In der einen Wandung 1 befindet sich eine Zuleitung 6, die mittelst eines geeigneten Schiebers geschlossen werden kann und mit einem Zuführungstrichter 7 in Verbindung steht. Diese Leitung 6 steht mit einem U-förmigen Troge 8 in Verbindung, der an seinem oberen Ende geschlossen ist, und welcher aus einzelnen Theilen zusammengesetzt werden kann. Der Trog wird durch die Wandungen 1, 1 und geeignete Gurtbogen getragen, so dafs der Trog die Erzbeschickung halten kann, während sein Inhalt möglichst stark der Wirkung der heifsen Luft und den Brennproducten des Ofens ausgesetzt ist.In one wall 1 there is a supply line 6, which is connected by means of a suitable slide can be closed and is connected to a feed funnel 7. These Line 6 is connected to a U-shaped trough 8 at its upper end is closed, and which can be composed of individual parts. Of the The trough is supported by the walls 1, 1 and suitable belt arches, so that the The trough can hold the ore charge, while its contents have as much effect as possible exposed to hot air and the products of the furnace.
Unterhalb des Troges 8 sind noch ähnliche Tröge g, 10 angeordnet, die durch ähnliche Gurtbogen getragen werden. Es können auch noch mehr als drei solcher Tröge angeordnet sein. Von dem Troge 8 führt durch die linke Wandung ein Kanal 11 nach dem darunter liegenden Trog 9. Dieser Trog 9 ist wiederum durch einen in der rechten Wandung befindlichen verticalen Kanal 12 mit dem Troge ι ο verbunden, während letztgenannter Trog in der linken Wandung mit einem schräg nach aufsen gerichteten, mit entsprechenden Schiebern versehenen Auslafskanal 13 ausgestattet ist. Aufserhalb des Ofens liegen geeignete Lagerböcke, in welchen hohle Wellen 14, 15, 16 drehbar gelagert sind. Diese Wellen führen durch die Tröge hindurch und besitzen innerhalb des Ofens vierkantige Querschnitte, während sie aufserhalb rund gestaltet sind. Die vierkantig gestalteten Stellen sind mit geeigneten Flügeln 17 ausgestattet, die durch Bolzen oder durch Stellschrauben mit der Welle befestigt sind. Die Flügel sind so geneigt, dafs das Material in dem einen Kanäle hin- und in dem darunterliegenden zurückgeführt werden mufs. In den Wandungen befinden sich an den den Trögen entsprechenden Stellen grofse Oeffnungen, welche durch entsprechend gestaltete Doppelthüren geschlossen werden, so dafs das Innere des Ofens leicht zugänglich ist.Below the trough 8 similar troughs g, 10 are also arranged, which by similar Belt arches are worn. More than three such troughs can also be arranged be. A channel 11 leads from the trough 8 through the left wall to the one below lying trough 9. This trough 9 is in turn by a located in the right wall vertical channel 12 connected to the trough ι ο, while the latter trough in the left wall with an obliquely outwardly directed, with corresponding sliders provided outlet channel 13 is equipped. Suitable ones lie outside the furnace Bearing blocks in which hollow shafts 14, 15, 16 are rotatably mounted. These waves run through the troughs and possess within of the oven square cross-sections, while they are designed round outside. the square shaped bodies are equipped with suitable wings 17, which are bolted or attached to the shaft by adjusting screws. The wings are so inclined that the material in one channel can be returned to the one below must. In the walls there are large openings at the places corresponding to the troughs, which pass through accordingly designed double doors are closed so that the interior of the furnace is easily accessible.

Sämmtliche Thüren sind in einer einzigen Gufsplatte angeordnet.All the doors are arranged in a single Gufsplatte.
Die Welle 15 ist mit Zahnrädern versehen, die mit auf den Wellen 14 und 16 angeordneten Zahnrädern im Eingriff stehen. Die erwähnten Zahnradgetriebe sind so eingerichtet, dafs die Welle 15 rascher als die Welle 14 und die Welle 16 rascher als die Welle 15 rotirt. Auf diese Weise mufs das Material in den unteren Trögen rascher befördert werden als in den oben gelagerten Trögen. Hiermit wird nicht nur die Möglichkeit des Zusammenballens vermieden, sondern, da das Material ■ bei seinem Durchgange durch den Ofen immer in heifsere Schichten gelangt, auch bewirkt, dafs der Querschnitt der Materialströmung geringer wird, und dafs somit die einzelnen Theile des Materials bedeutend schärfer der Hitze und den Brennproducten ausgesetzt werden. Vor- dem Lagerbocke dieser Lager liegen noch andere Lagerböcke, in welchen geeignete Stopfbüchsen gehalten werden; diese stehen mit einer Leitung L einerseits und mit den hohlen Wellen andererseits in Verbindung, so dafs durch die in dem Ofen der Glühhitze ausgesetzten Wellen ein Kühlmittel, wie Luft, Wasser oder Dampf, hindurchgeleitet werden kann.The shaft 15 is provided with gears which mesh with gears arranged on the shafts 14 and 16. The mentioned gear drives are set up in such a way that the shaft 15 rotates faster than the shaft 14 and the shaft 16 rotates faster than the shaft 15. In this way, the material in the lower troughs must be conveyed faster than in the troughs stored above. This not only avoids the possibility of agglomeration, but, since the material always gets into hotter layers as it passes through the furnace, it also has the effect that the cross-section of the material flow becomes smaller, and thus that the individual parts of the material are considerably sharper Exposed to heat and the products of the fire. In front of the pedestal of these bearings are other pedestals in which suitable stuffing boxes are held; these are connected to a line L on the one hand and to the hollow shafts on the other, so that a coolant such as air, water or steam can be passed through the shafts exposed to the glowing heat in the furnace.
Ebenso münden die Wellen auf den anderen Seiten des Ofens in geeignete Stopfbüchsen, die durch einen Ständer 20 getragen werden, und aus welchen das erhitzte Kühlmittel abgeleitet wird.The shafts also open into suitable stuffing boxes on the other sides of the furnace, which are supported by a stand 20 and from which the heated coolant is discharged will.
