Bei den Röhrentrocknern ist die Vorwärtsbewegung des Gutes vom Durchmesser der Rohre, vom Neigungswinkel und der Tourenzahl im wesentlichen abhängig. Das Gut durchläuft ein glattes Rohr, in "dem sich keine Wendeleisten befinden, in einer ununterbrochenen, regelmäßigen Schraubenlinie, deren Steigung von der Rohrneigung bedingt wird. Kommen nun Wendeleisten zur Benutzung, so wird die schraubenförmige Vorwärtsbewegung des Trockengutes in dem Augenblick unterbrochen, in welchem letzteres von der Wendeleiste berührt und angehoben wird. Das Gut verharrt in dieser Ruhelage so lange, bis die betreffende Wendeleiste eine Höhe erreicht hat, unter welcher das Trockengut abrutschen kann, um auf den senkrecht unter der Abrutschstelle befindlichen Teil der Rohrwand nieder zu fallen.In the case of tube dryers, the forward movement of the material depends on the diameter of the Tubes, essentially dependent on the angle of inclination and the number of revolutions. The good goes through a smooth tube, in which there are no spiral strips, in an uninterrupted, regular helical line, the slope of which is determined by the slope of the pipe. If turning strips are now used, this is how the helical forward movement of the material to be dried is at the moment interrupted, in which the latter is touched and lifted by the turning bar. That Well remains in this rest position until the turning bar in question reaches a height has, under which the dry goods can slide off, to the vertically below the slip point located part of the pipe wall to fall down.
Den Gegenstand vorliegender Erfindung bildet nun ein Wendegitter, welches in der Weise ausgebildet ist, daß die Längsstege des Wendegitters stellenweise durchschnitten und seitlich gerade oder nach Art einer Schraubenfläche so abgebogen sind, daß sie eine größere Neigung wie die Rohrachse erhalten. Auf diese Weise rutscht das Trockengut nicht wie bei den geraden Leisten senkrecht ab, sondern unter einem von dieser Senkrechten im Sinne der Bewegungsrichtung stark abweichenden Winkel, wodurch die durch das Wendegitter entstehenden Geschwindigkeitsverluste erheblich vermindert werden.The subject of the present invention now forms a turning grille, which in the way is designed that the longitudinal webs of the turning grille cut through in places and laterally straight or bent in the manner of a helical surface so that they have a greater inclination how to get the pipe axis. In this way, the items to be dried do not slide as they do with the straight ones Last vertically, but at an angle that strongly deviates from this vertical in terms of the direction of movement, which considerably reduces the speed losses caused by the turning grille will.
Auf der beiliegenden Zeichnung ist ein mit einem Wendegitter vorliegender Erfindung ausgerüstetes Trockenrohr veranschaulicht, und zwar zeigen:On the accompanying drawing is a present invention equipped with a turning grille Drying tube illustrated, namely showing:
Fig. ι und 2 ein solches in zwei Längsschnitten, Fig. Ι and 2 such in two longitudinal sections,
Fig. 3 dagegen einen Querschnitt durch dasselbe. 3, on the other hand, shows a cross section through the same.
Das Wendegitter b besteht. aus einem gelochten Blechstreifen, dessen Breite dem lichten Durchmesser des betreffenden Trockenrohres a entspricht; es kann daher leicht in das Rohr eingesetzt werden und genügen zum Festhalten desselben die kleinen Unebenheiten der Rohrwand und der Blechkanten, welche den erforderlichen geringen Widerstand hervorrufen, um das Gitter in seiner gegebenen Lage zu halten. Es können die Trockenrohre α mehrere hintereinander angeordnete kurze Gitter b besitzen, die dann entweder in einer Ebene oder versetzt zueinander stehen; ebenso ist nicht ausgeschlossen, die Gitter b selbst noch schraubenförmig zu verdrehen. Die Leisten oder Längsstege der Gitter b sind an beliebig vielen Stellen c zerschnitten und an den Schnittstellen entweder gerade oder nach Art einer Schraubenfiäche abgebogen. Die Abbiegungen bieten dann das Mittel, die Geschwindigkeitsverluste, die bei Anwendung ge- The turning grille b consists. from a perforated sheet metal strip, the width of which corresponds to the inside diameter of the relevant drying tube a; it can therefore be easily inserted into the pipe and the small unevenness of the pipe wall and the sheet metal edges are sufficient to hold it in place, which cause the necessary low resistance to hold the grid in its given position. The drying tubes α can have several short grids b arranged one behind the other, which are then either in one plane or offset from one another; it is also possible to twist the grids b themselves in a helical manner. The strips or longitudinal webs of the grids b are cut up at any number of points c and either straight or bent at the interfaces in the manner of a screw surface. The turns then offer the means of reducing the speed losses that
