Description

Schraubenförmig gewundene Wendeleiste für Röhrentrockner. Gegenstand der Erfindung ist eine Wendeleiste für Röhrentrockner, die aus einem schraubenförmig gewundenen Flacheisen gebildet ist. Die Neuerung an dieser an sich bekannten Wendeleiste besteht darin, daß der äußere Umfang der Schraubenwindungen mit Aussparungen versehen ist und daß die Tiefe der Aussparungen vom Anfang der Wendeleiste nach dem Ende derselben zu allmählich oder sprungweise abnimmt.Helical winding strip for tube dryers. object The invention is a spiral strip for tube dryer, which consists of a helical winding flat iron is formed. The innovation on this well-known reversible strip consists in that the outer circumference of the screw turns is provided with recesses and that the depth of the recesses from the beginning of the turning strip to the end the same decreases gradually or by leaps and bounds.

Der Gegenstand der Erfindung ist auf der Zeichnung beispielsweise dargestellt.The object of the invention is on the drawing, for example shown.

Abb. i zeigt die Wendeleiste in Seitenansicht, das Trocknerrohr im Längsschnitt. Abb. 2 zeigt die Wendeleiste in Stirnansicht, das Trocknerrohr im Querschnitt. Die Windungen der Wendeleiste a schließen mit ihrem äußeren Umfang dicht an die Wanduüg des Trocknerrohres b an. Erfindungsgemäß ist nun der äußere Umfang der Windungen mit Aussparungen c, cl, c2 versehen, die an der Wandung des Trocknerrohres Durchgangsöffnungen für einen Teil des Trocknergutes bilden. Die Tiefe dieser Aussparungen nimmt vom Anfang der Wendeleiste nach dem Ende derselben zu allmählich oder sprungweise ab.Fig. I shows the spiral strip in side view, the dryer tube in the Longitudinal section. Fig. 2 shows the turning bar in front view, the dryer tube in the Cross-section. The turns of the spiral bar a close with their outer circumference close to the wall of the dryer pipe b. According to the invention is now the outer The circumference of the turns is provided with recesses c, cl, c2, which are located on the wall of the Form the dryer tube through openings for part of the dryer material. the The depth of these recesses decreases from the beginning of the turning strip to the end of the same too gradually or by leaps and bounds.

Die neue Wendeleiste ist in bekannter Weise in dem Trocknerrohr angeordnet. Ihre Windungen laufen, von der Eintrittsseite aus gesehen, mit der Drehrichtung des Trockners, so daß sie auf das in dem Rohr befindliche Trockengut eine verzögernde Wirkung ausüben. Unter der Einwirkung der Drehung und der Achsenneigung des Trockners treten die Teile des Trockengutes, deren Durchmesser kleiner ist als die Tiefe der Aussparungen in der Wendeleiste, durch die Aussparungen hindurch, werden also von der Wendeleiste nicht beeinflußt, während die größeren Teile durch die Wendeleiste aufgehalten werden. Zunächst wird durch die tiefen Aussparungen c der größte Teil, des Trockengutes hindurchgehen, und nur die gröbsten Teile werden durch die Wendeleiste a zurückgehalten werden. Vor den weniger tiefen Aussparungen cl werden dann auch weniger grobe Teile zurückgehalten, und durch die noch flacheren Aussparungen c2 können nur noch kleinere Teile und das Feine hindurchtreten. Durch die neue Wendeleiste wird also die Durchlaufzeit der einzelnen Körnungen des Trockengutes durch den Trockner ungefähr der Korngröße und der davon abhängenden Trocknungsdauer angepaßt, derart, daß die gröberen Teile des Trockengutes, die ihre Feuchtigkeit schwerer abgeben; der Trocknung länger ausgesetzt sind als die feineren, schneller trocknenden Teile. Hierdurch wird eine größere Gleichmäßigkeit des Trocknungsgrades der verschiedenen Kbrnungen des Trockengutes erreicht, als bisher erzielt werden konnte.The new turning bar is arranged in the dryer tube in a known manner. Their turns run with the direction of rotation, seen from the entry side of the dryer, so that it has a delaying effect on the material to be dried in the tube Have an effect. Under the action of the rotation and inclination of the axis of the dryer occur the parts of the dry material, the diameter of which is smaller than the depth of the Recesses in the turning bar, through the recesses, are therefore of the turning bar is not influenced, while the larger parts are affected by the turning bar to get stopped. First of all, through the deep recesses c, most of the of the dry material go through, and only the coarsest parts are through the turning bar a be withheld. Before the less deep recesses cl are then also less coarse parts retained, and by the even shallower recesses c2 only smaller parts and the fine can pass through. With the new turning bar is the throughput time of the individual grain sizes of the dry material through the dryer approximately adapted to the grain size and the drying time that depends on it, in such a way that that the coarser parts of the dry material, which give off their moisture more difficult; are exposed to drying longer than the finer, faster drying parts. This ensures greater uniformity in the degree of dryness of the various The dry goods are more dry than previously achieved.
