Description
Schraubenförmig gewundene Wendeleiste für die Rohre von Röhrentrocknern Die Röhrentrockner Schulzscher Bauart, insbesondere für ,Braunkohle, sind mit schraubenförmig gewundenen Wendeleisten versehen, deren Durchmesser dem Innendurchmesser des Rohres entspricht und die beim Umlaufen des Trockners ein Umwälzen der Kohle herbeiführen.Helical winding strip for the tubes of tube dryers The Schulzscher type of tube dryers, especially for brown coal, are helical provided winding spiral strips, the diameter of which corresponds to the inner diameter of the pipe and which cause the coal to circulate as it rotates around the dryer.
Diese Wendeleisten haben aber den Nachteil, daß sie den freien Querschnitt des Rohres ausfüllen und dadurch den Abzug des Wrasens sehr erschweren. Bei der Trocknung kommt es darauf an, den Wrasen möglichst schnell von der Kohle zu entfernen, damit sich die frisch eintretende Luft von neuem mit Wasserdampf sättigt. Da nun die Wrasenmenge nach dem Ausfallende des Rohres hin immer größer wird, so macht sich die Querschnittsverengung durch die Wendeleisten besonders im hinteren Teil des Trockenrohres bemerkbar.However, these spiral strips have the disadvantage that they have the free cross-section of the pipe and thereby make it very difficult to extract the vapors. In the Drying depends on removing the vapor from the coal as quickly as possible, so that the freshly entering air is again saturated with water vapor. Because now the amount of vapor after the pipe has dropped out is always greater, so makes the narrowing of the cross-section due to the turning strips, especially in the rear part of the drying tube noticeable.
Diese Nachteile sollen nun durch die neue Ausbildung der schraubenförmig gewundenen Wendeleiste beseitigt werden. Die Erfindung besteht darin, daß der äußere Durchmesser der Windungen wesentlich kleiner gemacht wird als der Innendurchmesser des Rohres. Ferner wird diese Wendeleiste dann so am Ausfallende des Rohres befestigt, daß sie im Rohr einseitig anliegt, d. h. sie ruht in dem vorderen Teil des Rohres auf der unteren Wendung des Rohres. Der obere Teil des Rohres ist also vollkommen frei und ermöglicht einen guten Eintritt der Luft und einen leichten, widerstandlosen Abzug des Wrasens.These disadvantages are now due to the new design of the helical winding spiral strip can be eliminated. The invention consists in that the outer The diameter of the turns is made much smaller than the inner diameter of the pipe. Furthermore, this turning bar is then attached to the dropout of the tube, that it rests on one side in the pipe, d. H. it rests in the front part of the tube on the lower turn of the pipe. So the top of the pipe is perfect free and allows a good entry of the air and a light, resistance-free Discharge of the vapors.
Eine Ausführungsform der Anordnung ist auf der Zeichnung dargestellt. Abb. i zeigt das Rohr eines Röhrentrockners im Längsschnitt, Abb. 2 im Querschnitt. ' In das Rohr i ist die schraubenförmig gewundene Wendeleiste 2 eingelegt, welche einen wesentlich kleineren äußeren Durchmesser d besitzt als das Rohr selbst. Am Ausfallende 3 des Rohres ist die Wendeleiste mit dem Rohr verbunden. Diese Verbindung kann beispielsweise durch einen Klemmring q. erfolgen, an dem die Wendeleiste :2 befestigt ist. Im übrigen ist aber die Wendeleiste frei beweglich. Sie legt sich also besonders im vorderen Teil des Rohres auf dessen untere Wandung auf. Die Trockenluft tritt bei ein, während der Wrasen bei 6 abzieht; dem Durchgang der Luft bzw. des Wrasens wird somit kein Widerstand entgegengesetzt.An embodiment of the arrangement is shown in the drawing. Fig. I shows the tube of a tube dryer in longitudinal section, Fig. 2 in cross section. 'The helically wound spiral strip 2 is inserted into the tube i, which has a much smaller outer diameter d than the tube itself. Am Dropout 3 of the pipe, the turning bar is connected to the pipe. This connection can for example by a clamping ring q. where the turning bar: 2 is attached. Otherwise, however, the turning bar is freely movable. She lies down so especially in the front part of the tube on its lower wall. The dry air occurs at, while the vapor leaves at 6; the passage of air or the Wrasens is therefore not opposed to any resistance.
Da die Windungen der neuen Wendeleiste die untere Wandung des Trocknerrohres nur in je einem Punkte berühren, so können die feineren Kohlenteilchen, die schneller trocknen als die größeren, unter den Windungen hindurchtreten und daher das Rohr in kürzerer Zeit durchlaufen. .Hierdurch wird eine größere Gleichmäßigkeit der Trocknung erzielt.Because the windings of the new turning strip form the lower wall of the dryer tube only touch at one point each, so the finer coal particles can get the faster dry than the larger ones, pass under the turns and therefore the pipe run through in less time. This results in a greater uniformity of drying achieved.
