Description

Trocken- und Mahltrommel für feuchtes Gut Die Trocken- und Mahltrommel gemäß der Erfindung zeichnet sich durch die Einfachheit ihrer Bauart und große Wirtschaftlichkeit aus. Sie besteht aus einer mit einem Heizmantel ausgestatteten und um zwei hohle Achsenstümpfe drehbaren Trommel mit lose eingelegten Mahlkörpern. Hierbei ist der Heizmantel so ausgebildet, daß er die Trommel allseitig geschlossen umgibt. Das zu trocknende Gut wird der vereinten Wärme und Mahlwirkung ausgesetzt und in außerordentlich kurzer Zeit mit einer gegenüber den bekannten Trocknern nicht erreichten Dampfausnutzung zur völligen Trocknung und Staubfeinheit gebracht.Drying and grinding drum for moist material The drying and grinding drum according to the invention is characterized by the simplicity of its construction and great economy the end. It consists of one equipped with a heating jacket and two hollow ones Axle stubs rotating drum with loosely inserted grinding media. Here is the Heating jacket designed so that it surrounds the drum closed on all sides. That The material to be dried is exposed to the combined heat and grinding action and in an extraordinary way short time with a steam utilization not achieved compared to the known dryers brought to complete drying and fineness of dust.

Die Vorrichtung besteht aus einer drehbaren, mit einem Heizmantel B allseitig umschlossenen Trommel A, die auf zwei hohlen Achsenstümpfen a und b gelagert ist. Durch den Achsenstumpf a erfolgt eine Frischdampfzufuhr vermittels des Rohres c, während das Kondensat ständig durch das Rohr d abgeführt wird. Eine Buchsee schließt den HeizmantelB nach außen dicht ab. Die Beschickung der Trommel mit Naßgut erfolgt durch das Mannloch f, das sich an der Seite, bei größeren Trommeln an der Stirnfläche befindet. Der Abzug der Brüden erfolgt durch die Achse b, die gleichzeitig die Riemenscheibe g trägt. Im Innern der sich drehenden Trommel befinden sich in bekannter Weise Kugeln und Eisenteile, die für ständige Berührung des Naßgutes mit der Heizfläche sorgen und gleichzeitig die Zerkleinerung des Gutes bewirken. Die Wirtschaftlichkeit der Vorrichtung läßt sich noch weiterhin erhöhen, wenn. man mehrere zu einem Mehrkörperverdampfer vereinigt unter Nutzbarmachung des Brüdens aus dem Naßgut zur Beheizung weiterer Trommeln. Bei Ausführung der Trocknung im luftverdünnten Raum läßt sich die notwendige Saugleitung leicht in dem den Brüden abführenden Achsenstumpf einbauen.The device consists of a rotatable drum A which is enclosed on all sides by a heating jacket B and which is mounted on two hollow stub axles a and b. Live steam is supplied through the truncated axis a by means of the pipe c, while the condensate is continuously discharged through the pipe d. A Buchsee closes the heating jacket B tightly from the outside. The drum is loaded with wet material through manhole f, which is located on the side and, in the case of larger drums, on the end face. The exhaust of the vapors takes place through the axis b, which at the same time carries the belt pulley g. Inside the rotating drum there are balls and iron parts in a known manner, which ensure constant contact between the wet material and the heating surface and at the same time cause the material to be comminuted. The economy of the device can still be increased if. several are combined into a multi-body evaporator, making use of the vapor from the wet material for heating further drums. If the drying process is carried out in an air-diluted room, the necessary suction line can easily be installed in the stub shaft that removes the vapors.

Die bekannten Trockenvorrichtungen mit Heizmantel zeigen den Nachteil., daß der Mantel die Trommel nicht allseitig geschlossen umgibt. Hierbei entstehen Flächen, die nicht von Frischdampf umspült werden, so daß ein Anbacken der feuchten Massen begünstigt und somit die Beschaffenheit des getrockneten Gutes verschlechtert wird.The known drying devices with heating jackets have the disadvantage. that the jacket does not surround the drum closed on all sides. Here arise Surfaces that are not washed by live steam, so that the moist ones stick Favors masses and thus worsens the quality of the dried goods will.

Bei der Vorrichtung zum Trocknen und Mahlen feuchten Gutes gemäß der Erfindung wird dagegen nicht nur der Mantel in seiner Längsrichtung, sondern auch an seinen beiden Stirnflächen mit Frischdampf allseitig umspült, so daß die gesamte Oberfläche der Innentrommel an dem Trockenvorgang gleichmäßig teilnimmt. Hierdurch werden die Nachteile der Kondensation des Brüdendampfes und des Artbackens von' Trockengut mit Sicherheit vermieden.In the device for drying and grinding moist goods according to the In contrast, the invention is not only about the jacket in its longitudinal direction, but also about it Washed around on all sides with live steam at both of its end faces, so that the entire Surface of the inner drum participates in the drying process evenly. Through this the disadvantages of the condensation of the vapor and the kind of baking of ' Dry food definitely avoided.
