KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die bisher gebräuchlichen Vakuumtrockenvorrichtungen für Kautschuk, Guttapercha und dergl. trocknen den Stoff nur an den Oberflächen, während die inneren Schichten mehr oder weniger feucht bleiben. Um auch das Innere auszutrocknen, hat man Knetmaschinen benutzt, in denen die Masse erwärmt wurde. Gemäß der Erfindung werden beide Trockenverfahren kombiniert, indem dieThe previously used vacuum drying devices for rubber and gutta-percha and the like dry the fabric only on the surfaces, while the inner layers stay more or less moist. To dry out the inside too, kneading machines are used used, in which the mass was heated. According to the invention, both drying processes are combined by the

ίο Masse während des Trocknens in einem erwärmten Räume, aus dem die Luft abgesaugt wird, durchgeknetet wird.ίο mass while drying in a heated Rooms from which the air is sucked out is kneaded.

Die hierdurch erzielten Vorteile bestehen darin, daß die Trocknung sich gleichmäßig auf alle Teile der Masse erstreckt, daß man ferner statt zweier Vorgänge und Apparate nur einen anzuwenden hat, was eine Zeit- und Kostenersparnis bedeutet, und daß die Vereinigung des Knetens mit der Erwärmung und der Luftverdünnung die Anwendung niedrigerer Temperaturen und kürzerer Erwärmungsdauer gestattet, wodurch der Stoff geschont wird.The advantages achieved in this way are that the drying process is uniform extends to all parts of the mass, that instead of two processes and apparatuses has to use only one, which means a time and cost saving, and that the Combination of kneading with heating and air dilution, the use of lower temperatures and shorter heating times allowed, which protects the fabric.

Zur Ausübung des Verfahrens kann die bekannte Knetmaschine (Mastikator) nach entsprechender Abänderung dienen, wie sie auf der Zeichnung in Quer- und Längsschnitt dargestellt ist. Eine am Umfange wie üblich mit Längsrippen versehene Knetwalze a ist in einem luftdicht verschließbaren, unter Luftleere zu setzenden heizbaren Gehäuse b drehbar angeordnet. In das Gehäuse b wird die zu trocknende Masse von oben her nach Öffnung des äußeren und des inneren Gehäusedeckels m und / eingebracht. Die die Luft-Verdünnung erzeugende Pumpe setzt sich bei f an das Gehäuse b an und saugt durch die Durchbrechungen d des Deckels die Luft ab. Bei e sind Ablaßöffnungen vorgesehen.To carry out the process, the known kneading machine (masticator) can be used after appropriate modification, as shown in the drawing in cross-section and longitudinal section. A kneading drum a, which is provided with longitudinal ribs as usual, is rotatably arranged in a heatable housing b which can be closed airtight and is to be placed under vacuum. The mass to be dried is introduced into the housing b from above after opening the outer and inner housing covers m and /. The pump that generates the air dilution attaches itself to the housing b at f and sucks the air out through the openings d in the cover. Drain holes are provided at e.

Die Drehung der Walze α kann auf beliebige Weise erfolgen, z. B. von dem Vorgelege c aus mit Hilfe des Zahnradgetriebes g. Die Öffnungen h und i dienen für den Eintritt des Heizmittels in den Hohlraum k der Gehäusewandung b und für den Austritt aus diesem. Auch die Walze α kann in bekannter Weise mit einem heizbaren Hohlräume versehen sein.The rotation of the roller α can be done in any way, e.g. B. from the countershaft c with the help of the gear transmission g. The openings h and i serve for the entry of the heating medium into the cavity k of the housing wall b and for the exit from it. The roller α can also be provided with a heatable cavity in a known manner.
