Description

Verfahren zur Aufbereitung von Ton. Um plastische Tone handgerecht zumachen, ließ man sie bisher ausfrieren und im Anschluß daran lange Zeit faulen. Diese Art der Aufbereitung nahm eine große Spanne Zeit in Anspruch. Man mußte Jahre vergehen lassen, ehe die Tone gebrauchsfähig waren; abgesehen davon, daß das Material lange Zeit unbenutzt ruhen mußte und dadurch eine hohe Verzinsung der Förderungskosten bedingte, beanspruchte es noch notgedrungen Raum. Das Verfahren war also zeitraubend und kostspielig. Unplastische Tone galten bisher überhaupt als unbrauchbar.Process for the preparation of clay. In order to create plastic clays to close, they have previously been allowed to freeze out and then rot for a long time. This type of preparation took a long time. It took years let pass before the clays were usable; apart from that the material Had to rest unused for a long time and thus a high interest rate on the subsidy costs conditional, it still necessarily required space. So the process was time consuming and expensive. Up to now, non-plastic clays were generally considered unusable.

Gegenstand der Erfindung ist die Aufbereitung von Tonen jeglicher Art. Das geschieht in der Weise, daß die Tone mit einer Lösung durchsetzt werden, welche durch Behandlung organischer Stoffe, wie Holzmehl, Torfmehl, Fruchtabfälle o. dgl., mit schwefliger Säure erhalten werden.The subject of the invention is the processing of any clays Art. This is done in such a way that the clays are interspersed with a solution, which by treating organic substances such as wood flour, peat flour, fruit waste or the like, can be obtained with sulphurous acid.

Es wurde die überraschende Beobachtung gemacht, daß derartige Lösungen auf Tone überaus schnell einwirken und dadurch die Möglichkeit geben, sie in ,äußerst kurzer Zeit der Verarbeitung zuzuführen. Nicht nur erstreckt sich der Einfluß der Lösungen auf plastische, sondern auch unplastische Tone werden angegriffen und kennen in derselben Weise wie die plastischen weiterverarbeitet werden.The surprising observation was made that such solutions act on clays extremely quickly and thereby give them the opportunity to be extremely to be processed in a short time. Not only does the influence of the Solutions to plastic, but also to non-plastic clays are attacked and known processed in the same way as the plastic ones.

Die Lösungen, mit denen die Tone zu behandeln sind, werden erhalten, indem man auf organische Stoffe jeglicher Art schweflige Säure einwirken läßt. Beispielsweise behandelt man Holzmehl, Torfmehl, Fruchtabfälle usw. mit schwefliger Säure.The solutions with which to treat the clays are obtained, by allowing sulphurous acid to act on organic substances of any kind. For example if you treat wood flour, peat flour, fruit waste, etc. with sulphurous acid.

Besonders zweckmäßig ist es, zur Bereitung der Lösungen Abgase zu verwenden. Diese Art der Herstellung bietet den Vorteil, daß keine Gefahr der Oxydation der schwefligen Säure besteht. Außerdem vollziehen sich gleichzei;ig die Umsetzungen zwischen der schwefligen Säure und den organischen Stoffen in der Wärme, wodurch die Reaktion beschleunigt wird, ohne daß dabei besondere Kosten entstehen.It is particularly useful to prepare waste gases for the solutions use. This type of production has the advantage that there is no risk of oxidation the sulphurous acid consists. In addition, the conversions take place at the same time between the sulphurous acid and the organic matter in the warmth, whereby the reaction is accelerated without incurring any special costs.

Zur Erläuterung diene folgendes Beispiel: Holzmehl wird in Wasser suspendiert und schweflige Säure enthaltende Gase werden in die wäßrige Suspension geleitet. Nachdem die Umsetzungen beendet sind, wird durch Filtration o. dgl. die Lösung von den festen Bestandteilen abgetrennt. Mit der erhaltenen i Lösung werden die zu behandelnden Tone innig vermengt, beispielsweise durch Rühren, und dann sich selbst überlassen. Nach wenigen Wochen sind alsdann die Tone bei arbeitungsfähig.The following example serves as an illustration: Wood flour is in water Suspended and sulphurous acid-containing gases are added to the aqueous suspension directed. After the reactions are complete, filtration or the like Solution separated from the solid components. With the resulting i solution the clays to be treated are intimately mixed, for example by stirring, and then each other left to yourself. After a few weeks, the clays are then ready to work.

Durch die Erfindung ist es gelungen, die Aufbereitung der Tone, welche bisher Jahre beanspruchte, jetzt in wenigen Wochen durchführen zu können. Die Bedeutung liegt aber vor allem darin, daß nunmehr auch unplastische Tone, deren Verarbeitung bisher gänzlich unmöglich war, in derselben Weise und dem gleichen Umfange wie dieplastischen der Nutzbarmachung zugeführt werden können.The invention made it possible to prepare the clays, which previously claimed years, now to be able to perform in a few weeks. The meaning but lies above all in the fact that now also non-plastic Clays, whose processing was previously completely impossible, in the same way and the same The extent to which the plastic can be harnessed.
