Description

Verfahren zur Herstellung von Filtern aus Kohle Das Hauptpatent betrifft ein Verfahren zur Herstellung von Filtern ans Kohle, dessen Kennzeichen darin besteht, daß in einen aus ungebrannter Kohle 'bestehenden Behälter kleine Ringe aus ungebrannter Kohle eingebracht werden und daß der Behälter mit den Ringen gemeinsam so gebrannt wird; daß Behälter und Ringe ein 'zusammenhängendes Ganzes ergeben.Process for making filters from carbon The main patent relates to a process for the manufacture of filters on carbon, the distinguishing feature of which is that that in a container made of unfired coal 'small rings of unfired Charcoal are introduced and that the container with the rings burned together will; that containers and rings make a coherent whole.

Die vorliegende Erfindung -betrifft eine weitere Ausbildung des im Hauptpatent enthaltenen Erfntlunb gedankens. Gemäß der vorliegenden Erfindung wird vorgeschlagen, die kleinen Ringe allein miteinander durch gemeinsames Brennen zu einem einheitlichen Ganzen. zu verbinden und die aus ihnen hergestellten Formkörper in Behälter, z. B. in ein ;gebranntes Kohle- oder Graphitrohr oder aber einen anderen fertig gebrannten Behälter aus beliebigem Material, z. B. feuerfestem keramischem Material, einzusetzen. Das Verfahren gemäß der Erfindung bat den Vorteil, daß man zusammenhängende Körper aus Kohleringen in beliebiger Länge herstellen kann und den zusammenhängenden Körper in beliebig viele und beliebig lange Teile unterteilen kann, die man alsdann in die Behälter mit den entsprechenden Abmessungen einsetzt. Das gemeinsame Zusammenbrennen der Kohleringe kann zweclnnäßigerweise in Graphitrohren in der Weise geschehen, daß ein Anbacken von Kohleringen an die Wandungen des. Rohres verhindert wird.The present invention relates to a further embodiment of the im Main patent contained in the idea. According to the present invention suggested that the small rings be fired together by firing them together alone a unified whole. to connect and the moldings made from them in containers, e.g. B. in a; burnt carbon or graphite tube or another finished fired container made of any material, e.g. B. refractory ceramic Material to use. The method according to the invention had the advantage that one can produce coherent bodies from carbon rings of any length and divide the coherent body into any number and any length of parts can, which you then use in the container with the appropriate dimensions. The burning together of the carbon rings can be done in graphite tubes done in such a way that carbon rings stick to the walls of the pipe is prevented.

Ebenso, wie es im Hauptpatent bereits ausgeführt ist, -wird die die ungebrannte Kohle bildende Masse im der in der Kohletechnik üblichen Weise aus pulverisierter oder körniger Kohle und einem Zusatz von Bindemitteln zusammengesetzt. Als Bindemittel können Pech, Teer, Bitumen o. dgl. dienen. Die Menge der zuzusetzenden Bindemittel ist weiten Grenzen variierbar. Falls man ein Kohlepulver aus Hofkohle bei einer Temperatur von etwa. 50a verwendet, wird ungefähr ein Zusatz von 2o bis 25 % Bindemüttel, z. B. Teer, erforderlich sein, um dem geformten, ungebrannten Körper die notwendige Festigkeit zu verleihen. Das Brennen der Kohleringe wird bei den in der Kohletecluaik üblichen T'emp'eraturen durchgeführt. Diese liegen zwischen 90o und 150o°, je nach dem Grad der aalgestrebten Aktivität der Kohleringe.As already stated in the main patent, the mass forming the unfired coal is composed of pulverized or granular coal and an addition of binding agents in the manner customary in coal technology. Pitch, tar, bitumen or the like can serve as binders. The amount of binder to be added can be varied within wide limits. If you have a coal powder made from Hofkohle at a temperature of about. 50a is used, approximately an addition of 20 to 25 % binder, e.g. B. tar, may be required to give the shaped, unfired body the necessary strength. The burning of the coal rings is carried out at the usual temperature in coal technology. These are between 90o and 150o °, depending on the degree of eel-striving activity of the coal rings.
