Description

Drehrohrofen zum Brennen, Calcinieren, Rösten und Sintern von Gut aller Art Die Erfindung betrifft den Drehrohrofen zum Brennen, Calcinieren, Rösten und Sintern von Gut aller Art, z. B. Zement, nach Patent 689 239 mit Strahlungsbrücken, die in so kurzen Abständen schraubenartig versetzt angeordnet sind, daß sie dem hindurchströmenden Gase eine Drallbewegung geben.Rotary kiln for burning, calcining, roasting and sintering goods of all kinds The invention relates to rotary kilns for burning, calcining and roasting and sintering of all kinds of goods, e.g. B. cement, according to patent 689 239 with radiation bridges, which are arranged helically offset at such short intervals that they the give the gases flowing through a swirl movement.

Es hat sich als vorteilhaft herausgestellt, in diese Strahlungsbrücken ein oder mehrere Fenster oder Öffnungen einzubauen, die im wesentlichen senkrecht zur Strömungsrichtung der Abgase liegen. Hierdurch wird der Vorteil erreicht, daß .das auf den Brücken liegende Gut bei der Drehung des Ofens nicht auf der Brücke entlang läuft und seitlich abfällt, sondern schon vorzeitig durch die Fenster von der Brücke abfließt und in den Strom der Abgase regenartig niederriesel.t, wodurch ein lebhafter Wärmeaustausch zwischen dem Brenngut und den Gasen herbeigeführt wird. Derartige Öffnungen in längs verlaufenden Querwänden von Drehrohröfen vorzusehen, ist bekannt. Gemäß vorliegender Erfindung werden diese Öffnungen in den einzelnen Strahlungsbrücken versetzt, d. h. in verschiedenen Abständen vom Mantel angeordnet, so daß die einzelnen Rieselströme des Gutes jeweils mehr der Mittelachse des Ofens zu oder näher am Mantel und damit in verschiedenen Wärmezonen verlaufen. Die beiliegende Zeichnung veranschaulicht eine beispielsweise Ausführungsform der Erfindung.It has been found to be advantageous in these radiation bridges incorporate one or more windows or openings that are substantially perpendicular to the direction of flow of the exhaust gases. This has the advantage that . the goods lying on the bridges are not on the bridge when the furnace is turned runs along and falls off to the side, but prematurely through the window of the bridge flows off and trickles down like rain into the stream of exhaust gases, whereby a lively heat exchange between the material to be fired and the gases is brought about. Provide such openings in the longitudinal transverse walls of rotary kilns, is known. According to the present invention, these openings in the individual Staggered radiation bridges, d. H. arranged at different distances from the jacket, so that the individual trickle streams of the material each more to the central axis of the furnace to or closer to the coat and thus in different heat zones. The enclosed Drawing illustrates an example embodiment of the invention.

Abb. i und 3 stellen Querschnitte durch den Ofen dar mit je einer Brücke, während in Abb. 2 und q. eine Aufsicht auf die Brücken veranschaulicht wird.Fig. I and 3 show cross-sections through the furnace with one each Bridge, while in Fig. 2 and q. a plan view of the bridges is illustrated.

Der Drehrohrofena ist gemäß dem Hauptpatent mit einzelnen hintereinanderliegenden und schraubenartig versetzten Brücken b versehen. Die in diesen Brücken b vorgesehenen Fenster oder Öffnungen c oder d und f sind, wie die Abbildungen erkennen lassen, in den einzelnen Brücken versetzt, d. h. in verschiedenen Abständen vom Mantel angeordnet.According to the main patent, the rotary kiln is provided with individual bridges b, which are located one behind the other and are offset in the manner of a screw. The windows or openings c or d and f provided in these bridges b are, as the figures show, offset in the individual bridges, ie arranged at different distances from the jacket.

PATENTANSPRUCH: Drehrohrofen zum Brennen, Rösten und Sintern von Gut aller Art, z. B. Zement, nach Patent 689 239 mit im Innern, schraubenartig hintereinander versetzt angeordneten Strahlungsbrücken, dadurch gekennzeichnet, daß bei Anwendung der bekannten Öffnungen in längs verlaufenden Querwänden von Drehrohröfen die Öffnungen in den einzelnen Strahlungsbrücken versetzt, d. h. in verschiedenen Abständen vom Mantel angeordnet sind. PATENT CLAIM: Rotary kiln for firing, roasting and sintering all kinds of goods, e.g. B. cement, according to patent 689 239 with inside, helically offset one behind the other arranged radiation bridges, characterized in that when using the known openings in the longitudinal transverse walls of rotary kilns, the openings in the individual radiation bridges are offset, ie are arranged at different distances from the jacket.
