Description
Die Erfindung bezieht sich auf einen Rollförderrost zum Befördern von Rohren, Stangen od. dgl. in Wärmöfen. Dieser Roliförderrost soll einen möglichst langen Förderweg im Ofen ergeben und dadurch die Gewährleistung einer gleichmäßigen Durchwärmung des Fördergutes auch bei ungleichmäßiger Temperatur im Ofen. The invention relates to a roller conveyor grate for conveying of pipes, rods or the like in heating furnaces. This roller conveyor grate should be as possible long conveying path in the furnace and thereby ensuring a uniform Thorough heating of the material to be conveyed, even if the temperature in the oven is uneven.
Bekannt sind Roilförderroste, bei denen durch Anwendung gegenläufiger Schnecken eine reine Querbewegung des Fördergutes erhalten wird. Damit kann kein ausreichend langer Förderweg geschaffen werden. Roil conveyor grates are known, in which counter-rotating through application Screws a pure transverse movement of the conveyed material is obtained. With that no one can sufficiently long conveying path can be created.
Erfindungsgemäß wird dem Fördergut innerhalb des Ofens eine Zickzackbewegung erteilt, so daß es abwechselnd vorwärts und rückwärfs und gleichzeitig in Querrichtung verschoben wird, und zwar durch in axialer Richtung versetzt zueinander angeordnete verstärkte, abwechselnd zum Tragen kommende Abschnitte der Schneckenkerne. According to the invention, the material to be conveyed will move in a zigzag manner within the furnace so that it alternates forwards and backwards and at the same time in the transverse direction is displaced, namely by offset from one another in the axial direction Reinforced, alternating sections of the snail cores come into play.
Eine weitere Ausbildung des Erfindungsgegenstandes ist eine Anordnung, durch die das Fördergut von den tragenden Kernabschnitten der Förderschneckengruppe der einen Förderrichtung her den tragenden Kernabschnitten der gegenläufigen Schneckengruppe unter der Einwirkung der Schneckenfianken durch eine Rollbewegung auf festen Stützschienen zugeführt wird. Das Fördergut führt also im Verlauf der Zickzackbewegung in gewissen Zeitabständen eine Drehbewegung aus, so daß die Durchwärmung weiter vergleichmäßigt wird. Another embodiment of the subject matter of the invention is an arrangement through which the conveyed material from the supporting core sections of the screw conveyor group one direction of conveyance towards the supporting core sections of the counter-rotating screw group under the influence of the snail's fins through a rolling movement on fixed support rails is fed. In the course of the zigzag movement, the material to be conveyed thus leads in certain directions A rotary movement at intervals so that the heating is evened out further will.
Ein Ausführungsbeispiel ist in der Zeichnung schematisch dargestellt. An exemplary embodiment is shown schematically in the drawing.
Abb. I zeigt einen Teil eines Förderrostes in Draufsicht; Abb. 2 erläutert in größerem Maßstab das Zusammenwirken der Förderschnedcen und der Stützschienen mit dem Fördergut. Fig. I shows part of a conveyor grate in plan view; Fig. 2 explains on a larger scale the interaction of the conveyor cuts and the support rails with the conveyed goods.
Der Förderrost besteht aus einer Anzahl paralleler Schnecken I und 2. Von je zwei benachbarten gegenläufig angetriebenen Schnecken ist die eine, I, rechtsgängig und die andere, 2, linksgängig. The conveyor grate consists of a number of parallel screws I and 2. Of every two adjacent worms driven in opposite directions, one, I, right-hand and the other, 2, left-hand.
Der Kern einer jeden Schnecke ist m!it in gleichmäßigen Abständen angeordneten Verdickungen 1 a bzw. 2a versehen. Die Verdickungen I a der rechtsgängigen Schnecken I sind zu den Verdidungen 20 der linksgängigen Schnecken 2 in Richtung der Schneckenachse versetzt angeordnet, so daß das auf dem Rost liegende Fördergut 3 bei seiner durch die Flanken der Schneckengänge bewirkten Querbewegung abwechselnd auf den Verdickungen Ia und 20 der rechts- und linksgängigen Schnecken zur Abstützung gelangt und dadurch abwechselnd vor und zurückgeschoben wird. Der Übergang des Fördergutes von den Verdickungen der Schneckengruppe für die eine Förderrichtung zu den Verdikzungen der anderen Schneckengruppe erfolgt nicht unmittelbar, sondern unter Vermittlung fester Stützschienen 4, auf denen das Fördergut durch die Flanken der Schneckengänge in Querrichtung gerollt wird (vgl. Abb. 2). Es ergibt sich auf diese Weise ein Bewegungsverlauf des Fördergutes, der etwa dem in Abb. I strichpunktiert gezeichneten Linienzug entspricht.The core of every snail is m! It at regular intervals arranged thickenings 1 a and 2a provided. The thickenings I a the right-handed Screws I are towards the thickenings 20 of the left-handed screws 2 the screw axis arranged offset, so that the conveyed material lying on the grate 3 alternately in its transverse movement caused by the flanks of the worm threads on the thickenings Ia and 20 of the right-hand and left-hand worms for support and is thereby alternately pushed back and forth. The transition of the conveyed goods from the thickening of the screw group for one conveying direction to the thickening the other group of snails does not take place directly, but through mediation fixed support rails 4, on which the conveyed material through the flanks of the screw flights is rolled in the transverse direction (see Fig. 2). This results in a course of movement of the material to be conveyed, which roughly corresponds to the line drawing in Fig. I with a dash-dotted line.
Die Verdickungen der Schneckenkerne sind l dem Beispiel ballig dargestellt. Die Verdickungen können statt dessen auch zylindrische Form hal,en. The thickenings of the screw cores are shown in the example as spherical. The thickenings can instead have a cylindrical shape.
