Description

Mechanisch bewegter Walzenrost für Schachtöfen mit waagerecht gelagerten Walzen Den Gegenstand der Erfindung bildet ein mechanischer Walzenrost für vertikale Schachtöfen zum Brennen von Zement. Kalk, Magnesit usw.Mechanically moved roller grate for shaft furnaces with horizontally mounted Rollers The subject of the invention is a mechanical roller grate for vertical Shaft furnaces for burning cement. Lime, magnesite, etc.

Unter den. bekannten Ausführungen dieser Art gibt es schon solche, die allerdings zwei parallelachsige Brechwalzen als Rost enthalten. Das ergibt aber den Nachteil; daß das Brenngut sich an den außerhalb der Walzen gelegenen Stellen stauen kann, ohne von den Walzen erfaßt und bewegt zu werden.Under the. known designs of this type, there are already some which, however, contain two parallel-axis crushing rollers as grate. But that results the disadvantage; that the material to be fired is in the places outside the rollers can jam without being caught and moved by the rollers.

Demgegenüber unterscheidet sich der Erfindungsgegenstand dadurch, daß der Rost aus drei oder mehr waagerecht gelagerten Walzen besteht, deren Achsen kranzförmig um die Mitte angeordnet sind, so daß sich das Gut mindestens von drei Seiten her gegen die Ofenmitte bewegt.In contrast, the subject matter of the invention differs in that that the grate consists of three or more horizontally mounted rollers, their axes are arranged in a ring around the center, so that the good is at least three Moved sides towards the middle of the furnace.

Auf diese Weise wird das Arbeitsgut sehr wirksam von den Schachtwänden entfernt, kräftig nach der Mitte zu gequetscht, gebrochen und ausgetragen.In this way, the work material is very effectively removed from the shaft walls removed, strongly bruised towards the middle, broken and discharged.

In der Zeichnung ist ein Ausführungsbeispiel schematisch dargestellt.An exemplary embodiment is shown schematically in the drawing.

Abb. i ist ein senkrechter Schnitt durch den unteren Teil des Ofens, Abb. 2 ein Grundriß zu Abb. i, Abb.3, 4, 5 Grundrisse anderer Ausführungen.Fig.i is a vertical section through the lower part of the furnace, Fig. 2 is a plan of Fig. I, Fig. 3, 4, 5 plans of other designs.

Der Ofen hat einen Außenmantel a und ein Innenfutter b sowie den Schacht c.The furnace has an outer jacket a and an inner lining b as well as the shaft c.

Der Rost nach Abb. i und 2 besteht aus vier Stufenwalzen d, f, g, h, von denen, jede auf eine Welle aufgekeilt ist, welche zu ihrem Antrieb dient. Alle vier Walzen werden im Sinne der eingezeichneten Pfeile angetrieben; so daß ihre (las Gut tragenden Oberflächen sämtlich von außen nach der Mitte zu wandern. Die Walzen, welche auf ihrer Oberfläche mit Zähnen versehen sind, drängen das Gut nach der Mitte zu und trennen, während sie sich drehen, Teilchen vom Gut ab, die durch die Spalte i., k,"m, iz ausgetragen werden, welche zwischen den Walzen frei bleiben. Gleichzeitig wird ,beim Austragen das Gut gequetscht und gebrochen, so daß größere oder kleinere Stücke herauskommen, deren Größe man durch die Art der Zähne und durch den Abstand der Walzen regeln kann.The grate according to Fig. I and 2 consists of four stepped rollers d, f, g, h, each of which is keyed onto a shaft which is used to drive it. All four rollers are driven as indicated by the arrows; so that the surfaces carrying the goods all move from the outside to the center. The rollers, which are provided with teeth on their surface, urge the goods towards the center and, while they are rotating, separate particles from the goods which be discharged through the gaps i., k, "m, iz, which remain free between the rollers. At the same time, the material is squeezed and broken during discharge, so that larger or smaller pieces come out, the size of which can be determined by the type of teeth and can regulate by the distance between the rollers.

Die Abb. 3, 4, 5 zeigen ähnliche Anordnungen mit Doppelkegelwalzen.Figs. 3, 4, 5 show similar arrangements with double cone rollers.

Das Wesentliche in allen diesen Anordnungen ist, daß man drei oder mehr Walzen hat, deren Mittellinien nicht alle zu einander parallel sind und deren Drehsinn derart ist, daß die Oberfläche der Walzen, auf welchen das Gut im Innern des Schachtes aufruht, sich gegen die Schachtmitte bewegt. so daß das Gut von den Schachtwänden entfernt und dann ausgetragen wird.The essential thing in all of these arrangements is that you have three or has more rollers whose center lines are not all parallel to each other and whose The sense of rotation is such that the surface of the rollers on which the goods inside of the shaft rests, moves towards the center of the shaft. so that the good of the Manhole walls are removed and then discharged.
