Description

Verschleißfestes Rohr für den hydraulischen oder pneumatischen Transport von Schüttgütern und für andere Zwecke Die Erfindung verfolgt die Lösung .der Aufgabe, ein für den hydraulischen oder pneumatischen Transport von Schüttgütern, z. B. von Bergeversatz, in unterindischen Grubenbetrieben geeignetes Rohr zu entwickeln, bei Idem verschiedene wesentliche Nachteile der bisher bekannten Versatzrohre u. dgl. vermieden sind.Wear-resistant tube for hydraulic or pneumatic transport of bulk goods and for other purposes The invention pursues the solution. one for the hydraulic or pneumatic transport of bulk materials, e.g. B. from Bergeversatz to develop suitable pipe in lower Indian mining operations Idem various significant disadvantages of the previously known offset pipes and the like. are avoided.

Die Versatzrohre sind bekanntlich auf der Innenseite einer sehr starken Abnutzung durch die erodierende Wirkung des an laden Rohrwänden entlang schleifenlden Schüttgutes ausgesetzt. Zahlreiche Vorschläge zur Erhöhung feder Lebensdauer der Rohre sind bereits gemacht worden. Sie laufen im Grunde alle darauf hinaus, die Wandstärke der Rohre zu erhöhen. Mit einer Erhöhung der Wandstärke steigt aber das Eigengewicht der Rohre, was insbesondere für den Einbau der Rohre im Streb, d. h. dort, wo die Versatzleitungen häufiger umgelegt werden müssen, von wesentlichem Nachteil ist. The offset pipes are known to be on the inside of a very strong one Wear and tear due to the erosive effect of dragging along the pipe walls Bulk material exposed. Numerous suggestions for increasing the life of the spring Pipes have already been made. They basically all boil down to that To increase the wall thickness of the pipes. However, this increases with an increase in the wall thickness Dead weight of the pipes, which is particularly important for the installation of the pipes in the face, d. H. where the offset lines have to be relocated more often, of essential Disadvantage is.

Es ist ferner bereits vorgeschlagen worden, Blasversatzrohre mit einem Futter aus einem verschleißfesten Stoff, wie Hartguß, gehärtetem Stahl, Schmelzbasalt od. dgl., zu versehen. It has also already been proposed to use blowpipes a lining made of a wear-resistant material such as chilled cast iron, hardened steel, cast basalt or the like. To be provided.

Nach der Erfindung besteht das Versatzrohr aus einem Mantelrohr aus Leichtmetall, welches mit den zum Halten der üblichen Verbindungs- und Kupplungsmittel, wie Bunde, Schnellkupplungen u. dgl., dienenden Mittel ausgestattet ist, die vorzugsweise ebenfalls aus Leichtmetall bestehen, und welches ferner ein Futter aus einem verschleißfesten Stoff, wie Hartguß, gehärteter Stahl, Schmelzbasalt, Kupferhochofenschlaclçe od. dgl., umschließt. According to the invention, the offset tube consists of a jacket tube Light metal, which is used to hold the usual connecting and coupling means, Such as collars, quick-release couplings and the like., Serving means is equipped, which is preferably also made of light metal, and which also has a lining made of a wear-resistant Material such as chilled cast iron, hardened steel, cast basalt, copper blast furnace sluice or Like., encloses.

Erfindungsgemäß wird also ein spezifisch leichter, jedoch gegen Erosion nicht widerstandsfähiger Körper mit einer Aus fütterung eines Stoffes kombiniert, Ider bei höherem spezifischem Gewicht eine sehr hohe Widerstandsfähigkeit gegen Erosion hat. According to the invention, a specifically lighter, but against erosion non-resistant body combined with a lining of a fabric, With a higher specific weight, a very high resistance to Has erosion.

Verbundrohre dieser Art sind bisher noch nicht angewandt worden. Sie zeichnen sich dadurch aus, daß sie mit wesentlich geringerem Materialaufwand die gleiche Verschleißfestigkeit wie die bekannten Versatzrohre erreichen. Überdies - ergibt der Mantelkörper aus Leichtmetall Iden Vorteil, daß zdas Erosionsfutter bzw. die das Futter haltenlde- Vergußmasse fest an der Oberfläche des Leichmetall- -körpers haftet und sich davon infolge der günstigen thermischen Werte des Leichtmetalls auch bei örtlicher Erwärmung nicht löst.Composite pipes of this type have not yet been used. she are characterized by the fact that they use much less material achieve the same wear resistance as the known offset pipes. Besides - The shell body made of light metal gives the advantage that zdas erosion lining or the potting compound that holds the chuck firmly on the surface of the light metal -body adheres and is due to the favorable thermal values of the light metal does not dissolve even with local heating.

Vorzugsweise wendet die Erfindung ein Mantelrohr aus an sich bekanntem gewalztem oder gezogenem Material an, welches hohe Bruchfestigkeit mit geringem spezifischem Gewicht und geringem Eigengewicht verbindet. Indem Mantelrohr aus Leichtmetall wird das verschleißfeste Futter in geeigneter Weise befestigt. Beispielsweise kann man zwischen Futter und Mantelrohr einen Zwischenraum lassen, der nachträglich mit einem härtenden Bindemittel, etwa einem Zementmörtel od. sdgl., ausgegossen wird. Diese Befestigungsart kommt insbesondere für Futter aus keramischen Stoffen in Betracht. The invention preferably applies a jacket tube from what is known per se rolled or drawn material, which has high breaking strength with low specific weight and low weight. By casing pipe made of light metal the wear-resistant lining is attached in a suitable manner. For example, can you leave a gap between the lining and the jacket pipe, which can be a hardening binder, such as a cement mortar or the like., is poured. This type of fastening is particularly suitable for lining made of ceramic materials.

Man kann erfindungsgemäß das Futter vorteilhaft durch ein Schleudergußverfahren in dem According to the invention, the feed can advantageously be produced by a centrifugal casting process by doing
