Description
Filterkörper Zusatz zum Patent 543 o88 Zur Bildung von Filterrohren hoher Festigkeit werden gemäß dem Patent 543 o88 übereinandergeschichtete Filterringe aus Quarz, Kieselgur u. dgl. verwendet, die durch dünne, mit deren Stirnflächen innig verbundene Ringiben aiis Material höherer Festigkeit, wie Celluloid, Hartgummi o. dgl., verstärkt sind. Filter body addition to patent 543 o88 For the formation of filter tubes high strength filter rings are stacked according to the patent 543,088 Made of quartz, kieselguhr and the like. Used by thin, with their end faces intimately connected ring disks made of material of higher strength, such as celluloid, hard rubber o. The like., are reinforced.
Versuche haben nun ergeben, daß bei keramischen, eine Sinterung erfahrenden Filterkörpern von größerer Ringhöhe Verstärkungsringe auch innerlich eingelegt werden können, wenn sie mit einem bindenden Flußmittel, wie Glas oder Emaille, von größerer Schichtdicke überzogen sind oder ganz aus einem solchen Stoff (Glas) bestehen. Experiments have now shown that with ceramic, a sintering experience In filter bodies with a larger ring height, reinforcement rings can also be inserted internally Can, if used with a binding flux, such as glass or enamel, be of larger size Layer thickness are coated or consist entirely of such a substance (glass).
Die Verstärkung von Filterkörpern durch Einlagen ist an sich bekannt. Als Einlagen dienen bisher ebene oder gewellte Ringscheiben aus Blech, die mit porösen Masseschichten aus Asbest, Kieselgur, Kohle, Graphit und einem bindenden Zement oder Gips in abwechselnder Folge übereinandergeschichtet und mittels einer Spannschraube als Rohr zusammengehalten werden. Auch hat man schwer zu formende Filtergefäße, z. B. Gefäße mit einem halbkugel- oder ringrinnenförmigen Boden, in der Weise hergestellt, daß man ein die Gefäßform gebende Skelett aus gelochtem Blech oder Drahtgewebe mit einem von einem bindenden Zement durchsetzten Gemisch von Asbest, Bimsstein u. dgl. beiderseits belegte und den so gebildeten Filterkörper alsdann erhärten ließ. Um das metallische Skelett gegen Zerstörung durch chemische Einwirkung der Filterflüssigkeit zu schützen, verwendete man dabei bisweilen Drahtgewebe aus emaillierten Drähten. The reinforcement of filter bodies with inserts is known per se. So far, flat or corrugated ring disks made of sheet metal with porous Layers of mass made of asbestos, diatomite, coal, graphite and a binding cement or plaster of paris layered one on top of the other in an alternating sequence and by means of a clamping screw be held together as a tube. You also have filter vessels that are difficult to shape, z. B. Vessels with a hemispherical or annular bottom, manufactured in the manner that a skeleton made of perforated sheet metal or wire mesh giving the vessel shape a mixture of asbestos, pumice stone and the like interspersed with a binding cement. coated on both sides and then allowed to harden the filter body formed in this way. Around the metallic skeleton against destruction by chemical action of the filter fluid To protect, wire mesh made of enamelled wires was sometimes used.
Die Erfindung ist in der Zeichnung in einer beispielsweisen Ausführungsform dargestellt, und zwar im Schnitt durch einen Filterring. a ist ein poröser Filterkörper aus Quarz, Kieselgur o. dgl. b sind in dem Filterkörper liegende, von der porösen Filtermasse allseitig umgebene Verstärkungsringe aus einem Material höherer Festigkeit, insbesondere Eisen oder Metall, die mit einem Flußmittel c, wie Glas, Emaille 0. dgl., in einer Schichtstärke von ungefähr I bis 2 mm überzogen sind.The invention is shown in the drawing in an exemplary embodiment shown, in section through a filter ring. a is a porous filter body made of quartz, kieselguhr or the like. b are located in the filter body, from the porous one Reinforcing rings made of a material of higher strength, surrounded on all sides, in particular iron or metal that has been fluxed with a flux c, such as glass, enamel 0. Like., are coated in a layer thickness of about 1 to 2 mm.
Durch die starke Flußmittelschicht wird erreicht, daß sich beim Brennen des Filterkörpers die anliegenden Quarzkörnchen im Schmelzzustande mit dem schmelzenden Fluß mittel innig verbinden, und daß die Ausdehnung und das Zusammenziehen der Verstärkungsringe in dem Flußmittel unschädlich für den Zusammenhalt des Filterkörpers verläuft. The thick layer of flux ensures that it is fired when it is fired of the filter body the adjacent quartz grains in the melting state with the melting one Flux medium intimately connect, and that the expansion and contraction of the reinforcing rings runs in the flux harmless to the cohesion of the filter body.
Das zwischengeschaltete Flußmittel verhindert, daß der Filterkörper infolge der ungleichen Ausdehnung von Filtermasse und Einlage in den Ebenen der Einlagen rissig wird und auseinanderfällt.The interposed flux prevents the filter body as a result of the unequal expansion of filter material and insert in the levels of the Deposits will crack and fall apart.
An Stelle von mit einem Flußmittel überzogenen Verstärkungsringen können auch Ringe eingelegt werden, die ganz aus einem Flußmittel, z. B. Glas, bestehen. Die Erfindung gestattet es ferner, Drahtringe, einen in Schraubenlinie fortlaufenden Draht oder ein Netzwerk von Drähten einzulegen. Instead of reinforcing rings coated with a flux rings can also be inserted, which are made entirely of a flux, e.g. B. glass exist. The invention also allows wire rings, one continuous in a helical line Laying wire or a network of wires.
