Description

Verfahren zur Herstellung von Filterkörpern Gegenstand der Erfindung ist ein keramisches Filter aus Quarz, Korund oder anderen gleichwertigen feuerfesten Stoffen, das zum Reinigen n von Flüssigkeiten aller Art, insbesondere jedoch zum Reinigen von flüssigen Brennstoffen bestimmt ist.Process for the production of filter bodies The subject of the invention is a ceramic filter made of quartz, corundum or other equivalent refractory Substances that are used to clean liquids of all kinds, but especially for Purification of liquid fuels is intended.

Gegenüber dem bekannten Verfahren zur Herstellung von keramischen Filtern aus mehr oder weniger plastischen Massen, die durch Mischen der Grundstoffe, Quarz, Korund o. dgl., mit dem Bindematerial, sei es auf trockenem oder nassem Wege, erzeugt werden, stellt das vorliegende Verfahren etwas ganz Neues dar. Compared to the known method for producing ceramic Filters from more or less plastic masses, which by mixing the basic materials, Quartz, corundum or the like, with the binding material, be it dry or wet, are generated, the present process is something completely new.

Die Grundstoffe zur Herstellung von Filtern, z. B. Quarz und Korund, werden nicht mehr durch mechanisches knetendes Mischen mit dem Bindemittel vereinigt, wie oben angedeutet, sondern nach dem neuen Verfahren werden die Grundstoffe vor dem Formen und Brennen mit einem leicht sinternden, fein verteilten Bindemittel überzogen. Dieses Bindemittel von glasurartiger Zusammensetzung muß in äußerst feiner Aufschlämmung vorhanden sein, so daß nur ein Hauch an den Grundstoffen (Körnern) haftenbleibt. Erreicht wird dies dadurch, daß das körnige Ausgangsmaterial in das aufgeschlämmte Bindemittel, das z. B. aus einem Gemisch von Feldspat und Kaolin u. dgl. besteht, getaucht wird. Dies geschieht auf folgende Weise: Die Grundstoffe von geeigneter Korngröße werden lose auf ein feinmaschiges Sieb geschüttet und mit diesem in die Aufschläminung des Bindemittels getaucht. Nach dem Eintauchen läßt man den Uberschuß an Bindemittel ablaufen, gegebenenfalls unter Schütteln oder Schleudern. Die ganz gleichmäßig überzogenen Körner können nun in Formen eingestampft oder auch gepreßt werden, um hierauf gebrannt zu werden. Beim Brennen sintern die Körner an ihren Berührungspunkten zusammen. The basic materials for the manufacture of filters, e.g. B. quartz and corundum, are no longer combined with the binder by mechanical kneading mixing, as indicated above, but according to the new process, the raw materials are in front molding and firing with a slightly sintering, finely divided binder overdrawn. This binder of glaze-like composition must be extremely fine Slurry, so that only a touch of the raw materials (grains) sticks. This is achieved by the fact that the granular starting material in the slurried binders, e.g. B. from a mixture of feldspar and kaolin and the like. Is dipped. This is done in the following way: The basic materials of a suitable grain size are poured loosely onto a fine-meshed sieve and mixed with this dipped in the slurry of the binder. After dipping leaves you run off the excess binder, optionally with shaking or centrifuging. The evenly coated grains can now be pulped in molds or else pressed to be fired on. When fired, the grains sinter their points of contact together.

Der Vorteil der neuen Erfindung liegt darin, daß es jetzt möglich ist, ein Filter herzustellen, das wirklich gleichmäßig in der Struktur ist. Es kommen nicht mehr so viele Ausfälle beim Brennen vor. The advantage of the new invention is that it is now possible is to make a filter that is really even in structure. There come not as many failures when burning before.

Bei dem alten Verfahren war nicht die Möglichkeit vorhanden, das Bindemittel so fein zu verteilen, daß jedes einzelne Korn gleichmäßig von diesem überzogen war, wie dies nach dem neuen Verfahren erreicht wird. With the old method, there was no way that Distribute the binder so finely that every single grain of this is evenly distributed how this is achieved under the new process was excessive.
