KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Den Gegenstand der Erfindung bildet eine Neuerung an den Rührwerken von Zweiwalzentrocknern. The subject of the invention is an innovation in the agitators of two-drum dryers.
Oben zwischen den Walzen des Trockners ist, wie bekannt, ein Rührwerk mit achsial verlaufenden Stäben angebracht, die über die ganze Walzenlänge reichen und um die Achsen der Walzen als Drehpunkt schwingen. Hierdurch wird das Gut gelüftet, gleichmäßig verteilt und ständig an den Walzenflächen in Bewegung gehalten, so daß ein Zusammenbacken oder Festbrennen verhindert wird.As is well known, an agitator with axial is located at the top between the rollers of the dryer running bars attached, which extend over the entire length of the roller and around the axes the rollers swing as a fulcrum. This ventilates the material and distributes it evenly and kept constantly in motion on the roller surfaces, so that caking or sticking is prevented.
Die Erfindung besteht nun darin, daß die Stäbe des Rührwerkes tangential zu den Walzenoberflächen liegen.The invention consists in that the rods of the agitator tangential to the Roll surfaces lie.
In der Zeichnung zeigt: Fig. 1 eine Seiten-, ansieht und Fig. 2 eine Endansicht eines mit Rührvorrichtung versehenen Trockners.In the drawing: Fig. 1 shows a side, and FIG. 2 is an end view of an agitator-provided dryer.
Das Rührwerk besteht aus den über die ganze Walzenlänge reichenden Stäben a, die fest mit den Schwinghebeln b verbunden sind. Zur zwangläufigen Bewegung der Schwunghebel dient die Kuppelstange c. The agitator consists of rods a that extend over the entire length of the roller and are firmly connected to the rocker arms b . The coupling rod c is used for the forced movement of the rocker arm.
Der Antrieb des Rührwerkes erfolgt von beiden Seiten aus durch Exzenter oder ahnliehe Antriebe. Die Schwinghebel haben den gleichen Drehsinn, infolgedessen schwingen die beiden Stabgruppen a in entgegengesetzter Richtung und pressen das Gut abwechselnd in den Spalt, zwischen die Trockenwalzen d. Die Stäbe liegen tangential zu den Walzenflächen, infolgedessen bildet sich zwischen Walzenrundung und Stab ein natürlicher Keil, der sowohl beim Abwärts- wie Aufwärtsgang der Stäbe ein gleichmäßiges ■ Aufstreichen auf die gesamte Walzenoberfläche bewirkt.The agitator is driven from both sides by eccentrics or similar drives. The rocker arms have the same direction of rotation, as a result of which the two groups of rods a swing in opposite directions and alternately press the material into the gap between the drying rollers d. The bars are tangential to the roll surfaces, as a result of which a natural wedge is formed between the roll curvature and the bar, which causes an even brushing over the entire roll surface when the bars move downwards and upwards.
