Description

P A T E N T A N S P R U C H : Filterkerze nach Patent 601 279, dadurch gekennzeichnet. daß die schraubenförmige Dehnungsfeder (f) von einer Metallbüchse (g) von doppel-U -förmigem Längsquerschnitt umschlossen ist, in deren offenem Ende unter Einschaltung einer Dichtungspackung (p) ein hohlzylindrischer Paßkörper (r, s axial beweglich gelagert ist. P A T E N T A N S P R U C H: Filter cartridge according to patent 601 279, thereby marked. that the helical expansion spring (f) from a metal sleeve (g) is enclosed by a double-U -shaped longitudinal cross-section, in the open end thereof with the inclusion of a packing (p) a hollow cylindrical fitting body (r, s is mounted so that it can move axially.

Filterkerze Zusatz zum Zusatzpatent 601 279 Bei der Filterkerze nach dem Patent 601 279 dient zum Ausgleich der Rerzendehnungen eine schraubenförmige Dehnungsfeder, die zum Schutze gegen den Federstahl angreifende Filterflüssigkeiten und zur Erzielung einer geschlossenen Wand in einen hohlzylindrischen Gummikörper einvulkanisiert ist. Filter candle addendum to additional patent 601 279 the patent 601 279 is used to compensate for the expansion of the core, a helical one Expansion spring, the filter fluids used to protect against the spring steel and to achieve a closed wall in a hollow cylindrical rubber body is vulcanized. Das Aufvulkanisieren des Gummis auf die Schraubenfeder ist jedoch teuer, und es verschleißt der Gummi im Betriebe ziemlich stark; ferner ist Gummi bei der Behandlung vieler Flüssigkeiten z. B. konzentrierter Schwefelsäure, überhaupt nicht verwendbar.The vulcanization of the rubber on the coil spring is, however expensive, and the rubber in the factory wears rather heavily; furthermore is rubber in the treatment of many liquids e.g. B. concentrated sulfuric acid, at all not useable. Gemäß vorliegender Erfindung wird deshalb von der Verwendung von Gummi abgesehen und die Feder in einer nugförmigen Metallbüchse von doppel-U-förmigem Längsquerschnitt untergebracht, in deren offenes Ende ein hohlzylindrischer Paßkörper hineinragt. der hin und her gleitend die Längenänderungen der Filterkerze auf die Feder überträgt. Eine zwischen der Feder und dem ringförmigen Paßkörper liegende Pakkung schließt dabei den Federraum dicht ab. so daß die Ferder mit der Flüssigkeit nicht in Berührung kommt. According to the present invention, therefore, the use of Rubber apart and the spring in a nugget-shaped metal sleeve of double-U-shaped Housed longitudinal cross-section, in the open end of a hollow cylindrical fitting body protrudes. the back and forth sliding the changes in length of the filter candle on the Pen transmits. One between the spring and the annular fitting body Packing tightly seals off the spring space. so that the feathers with the liquid does not come into contact. Die Erfindung ist in der Zeichnung in einer beispielsweisen Ausführungsform veranschaulicht, und zwar zeigt Abt. 1 einen Längsschnitt durch eine hängende Filterkerze und Abb. 2 die ausgleichvorrichtung für Rerzendehnungen allein in etwas größerem Maßstabe. b ist das innere Tragrohr, dessen untere Spannmutter d das aus niedrigen Filtersteinringen a' zusammengesetzte Filterrohr a trägt. The invention is shown in the drawing in an exemplary embodiment illustrates, namely, Section 1 shows a longitudinal section through a hanging filter candle and Fig. 2 the compensating device for core expansion in a somewhat larger form Scale. b is the inner support tube, the lower clamping nut d of which is made of low Filter stone rings a 'composite filter tube a carries. Das in den äußeren Ringraum z gelangte Filtrat tritt in einer unteren, bruchfesten Kammerk durch Öffnungen i in das Tragrohr über und fließt durch das Tragrohr nach oben ab, während die den Abwurf der Kuchen und die Reinigung der Filterkörper bewirkende Preßluft den umgekehrten Weg nimmt.The filtrate that has entered the outer annular space z enters a lower, break-proof Kammerk through openings i in the support tube and flows through the Carrying tube upwards, while the dropping of the cake and cleaning of the filter body causing compressed air takes the opposite path. Gemäß der Erfindung ist die Dehnungsfeder f in einer hülsenförmigen Metallbüchse g von doppel-U -förmigem Längsquerschnitt angeordnet, in deren offenes Ende der zylindrische, in der Federbüchse g verschiebbare Hals r eines Paßkörpers s hineinragt. Zwischere der Dehnungsfeder f und dem Hals r des beweglich gelagerten Paßstückes s liegt eine gut dichtende Packung es die ein Eindringen von Flüssigkeit in den Federraum verhindert. According to the invention, the expansion spring f is in a sleeve-shaped Metal sleeve g of double-U -shaped longitudinal cross-section arranged in the open End of the cylindrical neck r of a fitting body, which can be displaced in the spring sleeve g s protrudes. Between the expansion spring f and the neck r of the movably mounted The fitting s is a well-sealed packing that allows the ingress of liquid prevented in the spring chamber. Die Federhülse g liegt auf dem inneren Tragrohr auf: über dem Federgehäuse g und unter dem Paßstück s sind dichtende Scheibenringe aus Gummi o. dg]. angeordnet. The spring sleeve g rests on the inner support tube: over the spring housing g and under the adapter s there are sealing washer rings made of rubber o. dg]. arranged. Sollen Flüssigkeiten gefiltert werden, die den Werkstoff des Federgehäuses angreifen würden, so werden die mit der Flüssigkeit in Berührung kommenden Flächen durch korrosionsfeste Überzüge, z. B. durch Verbleiung o. dgl.. gesichert. oder es wird das Federgehäuse ganz oder zum Teil aus korrosionsfestem Stoff hergestellt. If liquids are to be filtered that have the same material as the spring housing would attack, the surfaces that come into contact with the liquid become by corrosion-resistant coatings, e.g. B. secured by lead o. or the spring housing is wholly or partly made of corrosion-resistant material.
