KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei Trommeltrocknern wird vielfach, um das Gut möglichst lange dem die Trocknung herbeiführenden warmen Luftstrom auszusetzen, an der Auslaßöffnung eine Vorrichtung angebracht, die das Gut anstaut.In drum dryers, the drying process is often carried out to keep the goods as long as possible to expose warm air flow, attached to the outlet opening a device that accumulates the material.

ίο in der Zeiteinheit durch den Trockner hindurchzuschickende, zum Trocknen erforderliche Luftmenge nicht erreicht, so daß das Gut entweder nicht genügend austrocknet oder längere Zeit zum Trocknen erfordert, wodurch sich die Leistung des Trockners vermindert.ίο items to be sent through the dryer in the unit of time, The amount of air required for drying is not reached, so that the material either does not dry out sufficiently or takes a long time required for drying, which degrades the performance of the dryer.
Gegenstand der Erfindung ist eine Vorrichtung, die das Anstauen des Gutes ohne Verringerung des Luftstromquerschnittes ermöglichen soll.The invention is a device that the damming of the goods without reduction of the air flow cross-section should allow.
ao In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel dargestellt. Fig. 1 stellt eine Vorderansicht der Trockentrommel dar, und Fig.. 2 und 3 zeigen verschiedene Stellungen einer einzelnen Öffnung der in Fig. 1 dargestellten Trommel. Auf der Achse einer drehbaren, mit mehreren Einzelkammern und Auslaßöffnungen b versehenen Trockentrommel α ist eine ebenfalls drehbare Scheibe c angeordnet, in der sich die gleiche Anzahl Ausfallöffnurigen d für das Gut befinden, wie Kammern und Auslaßöffnungen b in der Trommel α vorhanden sind. Die Ausfallöffnungen d .sind hierbei kleiner als die Öffnungen b der Trockentrommel α. An den Längskänten g. der Öffnungen d ist je eine schräg nach aufwärts gerichtete Wand e, die angeschraubt oder mit der Scheibe aus einem Stück bestehen kann, angebracht, so daß beim Stauen von Gut der Austrittsquerschnitt f stets gleich bleibt. Befindet sich die Vorrichtung in der in Fig. 2 dargestellten Lage, so kann das getrocknete Gut, ohne erheblich angestaut zu werden, den Trockner verlassen. Wenn dagegen das. Gut in der Trommel sich anstauen soll, wird die Scheibe c durch Drehen in der Pfeilrichtung in die in Fig. 3 dargestellte Lage gebracht, so daß das Gut sich an der unterhalb der Öffnung d liegenden Wand der Scheibe c anhäufen kann, ohne daß eine Verringerung des Luftstromquerschnittes stattfindet, der, wie aus der Zeichnung ersichtlich, in beiden Lagen unverändert bleibt.ao In the drawing, the invention is shown using an exemplary embodiment. 1 shows a front view of the drying drum and FIGS. 2 and 3 show various positions of a single opening of the drum shown in FIG. On the axis of a rotatable drying drum α , provided with several individual chambers and outlet openings b , a likewise rotatable disk c is arranged, in which the same number of discharge openings d are for the material as there are chambers and outlet openings b in the drum α . The discharge openings d. Are here smaller than the openings b of the drying drum α. On the lengthways g. the openings d each have an upwardly inclined wall e, which can be screwed on or made of one piece with the disk, so that the exit cross-section f always remains the same when goods are stowed. If the device is in the position shown in FIG. 2, the dried material can leave the dryer without being significantly accumulated. If, on the other hand, the material is to accumulate in the drum, the disc c is brought into the position shown in FIG. 3 by turning in the direction of the arrow, so that the material can accumulate on the wall of the disc c located below the opening d. without a reduction in the air flow cross-section, which, as can be seen from the drawing, remains unchanged in both positions.
