KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
Nach dem durch die brit. Patentschrift 26074/07 vorveröffentlichten Verfahren des Hauptpatents soll Kork bei Temperaturen über 200° behandelt werden, wodurch eine Volumenzunähme des Korks und eine chemische Umwandlung desselben eintritt, welche die gleichzeitige Vereinigung der losen Korkteilchen zu einer festen Masse ermöglicht.According to the process of the prior published by British patent specification 26074/07 The main patent is intended to treat cork at temperatures above 200 °, causing an increase in volume of the cork and a chemical transformation of the same occurs, which is the simultaneous Unification of loose cork particles into a solid mass is possible.
Es hat sich nun herausgestellt, das dieses Verfahren sich in besonders vorteilhafter Weise ausführen läßt, wenn man über die für das bekannte Verfahren angegebene Grenze sehr erheblich hinausgeht, und zwar hat das Arbeiten bei ungefähr 400 ° C gute Resultate ergeben. It has now been found that this method is particularly advantageous can be carried out if one is very much above the limit indicated for the known method goes significantly beyond, and working at about 400 ° C has given good results.
Dies gilt zunächst für das gewonnene Erzeugnis. Bei dieser Temperatur erhalten die Korkzellen die maximale Ausdehnung, deren sie überhaupt fähig sind. Andererseits gehen bei dieser Temperatur Destillationsprodukte weg, durch deren Weggang das Korkerzeugnis in noch vorteilhafterer Weise beeinflußt wird wie nach dem bekannten Verfahren. Es findet eine erhebliche Steigerung aller gün-.25 stigen Eigenschaften statt.This applies first of all to the product obtained. At this temperature, the Cork cells the maximum expansion that they are ever capable of. On the other hand go at this temperature distillation products are gone, the cork product being removed is influenced in an even more advantageous manner than according to the known method. It there is a considerable increase in all favorable properties.
Da die Korkteilchen diese Temperatur durch und durch besitzen sollen, treten die in der brit. Patentschrift 26074/07 geschilderten Schwierigkeiten einer schnellen, für gewerbliche Verwertung brauchbaren Erhitzung in erhöhtem Maße auf. Diese Schwierigkeiten bestehen sowohl in der Erteilung der hohen Temperatur in kurzer Zeit wie in der Vermeidung der Entzündung des Korks.Since the cork particles should have this temperature through and through, they occur in the British patent specification 26074/07 described difficulties of a fast, for commercial Recovery usable heating to an increased extent. These difficulties exist both in the issuance of the high Temperature in a short time as in avoiding the inflammation of the cork.
Vorteilhaft nimmt man die Erhitzung des Korks in einem geneigten rotierenden Ofen vor. Diesen Ofen durchwandert das Korkschrot in einer mehr oder weniger dichten Schicht im Gegenstrom oder Gleichstrom mit Gasen, die zweckmäßig durch Verbrennung erzeugt und an dem einen Ende der Trommel eingeleitet werden.It is advantageous to heat the cork in an inclined rotating oven before. The cork grist wanders through this furnace in a more or less dense manner Layer in countercurrent or cocurrent with gases, expediently by combustion generated and introduced at one end of the drum.
Bei dieser Art der Erhitzung, bei welcher die Oberflächen des einzelnen Korkteilchens fortwährend an verschiedenen Stellen mit den heißen Gasen und der heißen Trommelwand in Berührung treten, kann man die Hitze des Gases auf 600 bis 700° C steigern, ohne daß eine Zerstörung der Korkzelle und eine schädliche Verkohlung eintritt. Die Gase, als welche zweckmäßig, die Abgase eines besonderen Generators benutzt werden, bedürfen bei dieser Temperatur nur einer Einwirkungsdauer von 10 bis 20 Minuten, um Korkklein gewöhnlicher Art, dessen einzelne Stücke ungefähr Nußgröße haben oder solche Abmessungen, daß sie sich bequem fortbewegen lassen, vollständig auf die Temperatur vonWith this type of heating, in which the surfaces of the individual cork particles continuously in different places with the hot gases and the hot drum wall in Contact, you can increase the heat of the gas to 600 to 700 ° C without destruction of the cork cell and harmful charring occurs. The gases, as which are expedient to use the exhaust gases from a special generator at this temperature only an exposure time of 10 to 20 minutes to cork small ordinary type, the individual pieces of which are approximately the size of a nut or such dimensions, that they can be moved easily, completely to the temperature of
400° C zu bringen, wenn sie den Ofen an seinem unteren Ende verlassen.Bring 400 ° C when they leave the oven at its lower end.
Die Entwicklung der Destillationsprodukte wird hierbei eine derart lebhafte, daß der Kork bis zu 30 bis 50 Prozent seines Eigengewichtes verliert. Die Farbe verändert sich dabei auch, und der gelbbraune Ton geht in einen grauen über. Die Ausstoßung der Deitillationsprodukte findet auch noch eine Zeitlang nach dem Verlassen des Ofens statt.The development of the distillation products is so vigorous that the Cork loses up to 30 to 50 percent of its own weight. The color changes at the same time, and the yellow-brown tone turns gray. The expulsion of the Dilution products also take place for some time after leaving the oven.
Claims (1)
Ausführungsform des Verfahrens nach Patent 267733 zur Behandlung von Kork unter Erhitzung, darin bestehend, daß der Kork in einer drehenden Trommel durch einen Gasstrom von einer Temperatur bis ungefähr 600 ° auf höchstens 350 bis 400 ° so lange erhitzt wird, bis die Korksubstanz 30 bis 50 Prozent an flüchtigen Bestandteilen verloren hat.Patent claim:
Embodiment of the method according to patent 267733 for the treatment of cork with heating, consisting in that the cork is heated in a rotating drum by a gas stream from a temperature of about 600 ° to a maximum of 350 to 400 ° until the cork substance is 30 to 50 Percent of volatile matter has lost.
