Description
Drehbare Trockentrommel für staubiges Gut Die für die Trockenprozesse verwendeten, an sich wirtschaftlichen Trockentrommeln sind in den bekannten Ausführungsformen nicht brauchbar, wenn es sich um Trockengut handelt, in dem viel feiner und leichter Staub enthalten ist oder während des Trocknungsvorgangs entwickelt wird. Die bei den bekannten Trockentrommeln abziehenden Staubmengen können nur schwierig unter Verwendung von teuren mechanischen oder elektrischen Filtern oder durch große Staubkammern zurückgewonnen werden. In vielen solcher Fälle ist man auf die teure Vakuumtrocknung angewiesen.Rotatable drying drum for dusty goods Die for the drying processes used, economical drying drums are in the known embodiments not usable when it comes to dry goods, in which it is much finer and lighter Contains dust or develops it during the drying process. The at the known drying drums pulling dust quantities can only with difficulty under Use of expensive mechanical or electrical filters or large dust chambers to be recovered. In many such cases one is on the expensive vacuum drying reliant.
Durch die Trockentrommel gemäß der Erfindung werden diese Schwierigkeiten beseitigt.The drying drum according to the invention eliminates these difficulties eliminated.
Auf der Zeichnung ist ein Ausführungsbeispiel der neuen Trommel dargestellt. Die Trockentrommel besteht aus einem mit Sieböffnungen versehenen Zylinder, der von einem geschlossenen Hohlmantel umgeben ist. Das Trockengut tritt durch die Schurre a in den inneren Zylinder b ein, der von den Feuergasen der Heizung h in Gleichstrom mit dem Trockengut durchzogen wird. Der Zwischenraum c zwischen innerem und äußerem Zylinder steht durch die Sieböffnungen d mit dem Innenraum der Trommel in Verbindung. Durch diese Sieböffnungen werden die feinen Teile des Trockengutes aus dem Bereich der strömenden Feuergase unmittelbar abgeführt und dem getrennten Auslaufe zugeleitet. Der feine Staub befindet sich also in der zugfreien Zone des Zwischenraumes c und kann von den Feuergasen nicht mehr mitgeführt werden. Etwa doch vom Gasstrom mitgenommene Staubteilchen werden durch das konische Sieb e und den Fangteller f, der mit röhrenförmigen Armen g versehen ist, aufgefangen und ebenfalls in den Raum c befördert.In the drawing, an embodiment of the new drum is shown. The drying drum consists of a cylinder with screen openings, the is surrounded by a closed hollow jacket. The dry material passes through the chute a into the inner cylinder b, that of the fire gases of the heater h in direct current is permeated with the dry material. The space c between inner and outer The cylinder is in communication with the interior of the drum through the sieve openings d. The fine parts of the dry material are removed from the area through these sieve openings the flowing fire gases are discharged immediately and fed to the separate outlet. The fine dust is therefore in the draft-free zone of the space c and can no longer be carried by the fire gases. Perhaps taken away by the gas stream Dust particles are passed through the conical sieve e and the collecting plate f, the one with the tubular Arms g is provided, caught and also conveyed into space c.
