Description
Die vorliegende Erfindung betrifft
eine Mörtelmischpumpe
gemäß dem Oberbegriff
des Patentanspruchs 1. Eine solche Mörtelmischpumpe ist aus der
Mörtelmischpumpen der genannten Art dienen zum vollautomatischen Mischen von Trockenmaterial wie Fertigmörtel, Zement und ähnlichem Material, das vornehmlich als Sackware oder in Silos angeliefert wird und zur Verwendung mit Wasser sowie gegebenenfalls weiteren Zusatzstoffen gemischt werden muss. Mörtelmischpumpen finden beispielsweise im Tunnelbau Anwendung.Mortar mixing pumps of the type mentioned serve for the fully automatic mixing of dry material like ready-mixed mortar, Cement and the like Material that is mainly delivered as sacks or in silos is and for use with water and possibly other Additives must be mixed. Mortar mixing pumps can be found, for example in tunneling application.
Obwohl Mörtelmischpumpen der im Oberbegriff genannten Art schon eine bedeutende Verbesserung gegenüber früher üblichen Vorrichtungen darstellen, bestehen nach wie vor Probleme dahingehend, dass sich Ablagerungen im Bereich der Mischkammer bilden und insbesondere der Mischkammerbereich schwer zu reinigen ist.Although mortar mixing pumps in the generic term mentioned type already a significant improvement over previously common Devices, there are still problems with that deposits form in the area of the mixing chamber and in particular the mixing chamber area is difficult to clean.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Mörtelmischpumpe anzugeben, die weniger anfällig für Ablagerungen ist, deshalb weniger Reinigungsaufwand erfordert und insgesamt leichter zu reinigen ist.The object of the invention is therefore based on a mortar mixing pump specify the less vulnerable for deposits is therefore requires less cleaning effort and is easier overall is clean.
Diese Aufgabe ist erfindungsgemäß mit einer Mörtelmischpumpe gelöst, die die im Patentanspruch 1 angegebenen Merkmale aufweist.This task is according to the invention with a Mortar mixing pump solved, which has the features specified in claim 1.
Erfindungsgemäß ist demnach die Förderschnecke, die das zu vermischende Material in die Mischkammer fördern soll, nicht mehr in einem Mischrohr, sondern in dem unteren Teil eines Trichters zum Einfüllen des zu vermischenden Materials angeordnet. Die Fortsetzung des Trichters bis in den Bereich um und unter die Förderschnecke verbessert deren Fördervermögen, insbesondere durch eine Vergleichmäßigung des Materialflusses, weil in diesem kritischen Bereich jetzt keine störenden Kanten und Übergänge zwischen Metallteilen und einer Auskleidung mehr existieren. Totzonen und die sich damit ergebende Gefahr der Bildung von Ablagerungen, zu der es beim Stand der Technik vorwiegend an den Übergangsstellen zwischen einem Einfülltrichter und der Auskleidung eines Mischrohres kommen konnte, werden auf diese Weise vermieden. Der Trichter kann einstöckig oder auch zweiteilig mit insbesondere einer Querteilung ausgeführt sein.According to the invention, the screw conveyor is which is to convey the material to be mixed into the mixing chamber, no longer in a mixing tube, but in the lower part of one Funnels for filling of the material to be mixed arranged. The continuation of the funnel to the area around and under the screw improves their Funding assets, in particular by making the Material flow, because in this critical area there are no annoying edges and transitions between Metal parts and one more lining exist. Dead zones and the resulting risk of deposits forming which in the prior art is predominantly at the transition points between one Hopper and the lining of a mixing tube could come on this Avoided way. The funnel can be built in one or two parts in particular a cross division.
Die sich an den Trichter anschließende Mischkammer ist erfindungsgemäß ein vom Trichter und auch vom Pumpenflansch separates, mit dem Trichter verbundenes Bauteil, welches über seine gesamte Länge mit einer Auskleidung aus vorzugsweise Polyurethan, Polyethylen oder Silikon versehen ist. Die Auskleidung kann durch Ausspritzen der zylindrischen Mischkammer oder auch durch Einsetzen eines entsprechenden, vorgefertigten Formteils erzeugt werden. Ein solches Formteil kann an seiner mit Metall zu verbindenden Seite auch eine Gummischicht aufweisen, die mit dem Polyurethan-, Polyethylen- oder Silikonmaterial einen Verbund bildet und die beispielsweise mit dem Metall verklebt wird. Die Auskleidung stellt eine sehr glatte und robuste innere Oberfläche bereit, an der das zu vermischende Material praktisch nicht haften bleibt. Vorzugsweise ist die Auskleidung so gestaltet, dass sich beim Übergang vom Trichter zur Mischkammer ein stufenloser Übergang ergibt.The mixing chamber adjoining the funnel is a according to the invention Funnel and also separate from the pump flange, with the funnel connected component, which over its entire length with a lining of preferably polyurethane, polyethylene or silicone is provided. The lining can be sprayed out the cylindrical mixing chamber or by inserting an appropriate prefabricated molded part are generated. Such a molded part can on its side to be connected with metal also a rubber layer have with the polyurethane, polyethylene or silicone material forms a composite and glued to the metal, for example becomes. The lining provides a very smooth and robust inner surface, to which the material to be mixed practically does not stick. The lining is preferably designed in such a way that the transition from Funnel to the mixing chamber gives a smooth transition.
Der die Mischkammer am pumpenseitigen Ende begrenzende Pumpenflansch ist vorzugsweise auf seiner der Mischkammer zugekehrten Seite im gesamten mörtelführenden Bereich mit einer Abdeckung aus Polyurethan, Polyethylen oder Silikon versehen, die in unmittelbarem Kontakt mit der Auskleidung der Mischkammer steht. Die Abdeckung des Pumpenflansches kann ebenfalls beispielsweise durch Aufspritzen von Polyurethanmaterial auf die gewünschten Flächen des Pumpenflansches erzeugt werden. Eine andere Möglichkeit besteht darin, ein vorgefertigtes Formteil in eine Durchgangsöffnung des Pumpenflansches einzuknöpfen.The mixing chamber at the pump end delimiting pump flange is preferably on its the mixing chamber facing side in the whole mortar Area with a cover made of polyurethane, polyethylene or silicone provided in direct contact with the lining of the mixing chamber stands. The cover of the pump flange can also be covered, for example Spraying polyurethane material onto the desired surfaces of the pump flange. Another possibility consists of a prefabricated molded part in a through opening of the Button in the pump flange.
Erfindungsgemäß ist des weiteren eine Mehrzahl von Flüssigkeitseinspritzdüsen in einem Düsenträger aufgenommen, der in einer Aussparung der Auskleidung zumindest annähernd bündig mit der Innenfläche der Auskleidung angeordnet und durch von außerhalb der Mischkammer zugängliche Befestigungsmittel lösbar befestigt ist. Diese Art der Ausführung reduziert zum einen beträchtlich die Gefahr der Bildung von Ablagerungen im Bereich der Flüssigkeitseinspritzdüsen und ermöglicht zum anderen eine einfachere Reinigung der Flüssigkeitseinspritzdüsen, indem die Befestigung des Düsenträgers von außen gelöst und der Düsenträger dann nach innen aus der Mischkammer herausgenommen werden kann. According to the invention, there is also a plurality received by liquid injection nozzles in a nozzle carrier, in a recess in the lining at least approximately flush with the Inner surface arranged of the lining and by means of fasteners accessible from outside the mixing chamber solvable is attached. On the one hand, this type of execution reduces considerably the risk of deposits forming in the area of the liquid injection nozzles and allows secondly, easier cleaning of the liquid injection nozzles by the attachment of the nozzle holder from Outside solved and then the nozzle holder can be removed from the inside of the mixing chamber.
In ihrer Gesamtheit verbessern die genannten Merkmale der erfindungsgemäßen Mörtelmischpumpe das Betriebsverhalten und die Wartbarkeit erheblich.In total, they improve Features mentioned of the mortar mixing pump according to the invention the operating behavior and maintainability significantly.
Die erfindungsgemäße Anordnung der Flüssigkeitseinspritzdüsen in einem Düsenträger gestattet es auf einfache Art und Weise, unterschiedliche Einspritzwinkel zu realisieren. Jede gewünschte Konfiguration ist darstellbar, beispielsweise können alle Flüssigkeitseinspritrdüsen unterschiedliche Einspritzwinkel aufweisen, ebenso können einige der Flüssigkeitseinspritrdüsen denselben Einspritzwinkel aufweisen und selbstverständlich können auch alle Flüssigkeitseinspritrdüsen den gleichen Einspritzwinkel haben. Es wird jedoch in der Regel bevorzugt sein, wenigstens zwei unterschiedliche Einspritzwinkel vorzusehen, um eine schnellere und gleichmäßigere Durchfeuchtung des zu vermischenden Materials zu erreichen.The arrangement of the liquid injection nozzles according to the invention in one Nozzle holder allowed it in a simple way, different injection angles to realize. Any desired Configuration can be displayed, for example, all liquid injection nozzles can be different Have injection angles, as well as some of the liquid injection nozzles the same Have injection angle and of course all liquid injection nozzles have the same injection angle. However, it will usually be preferred to provide at least two different injection angles to faster and more even moisture penetration of the material to be mixed.
Die Flüssigkeitseinspritrdüsen können erfindungsgemäß in dem Düsenträger selbst ausgebildet sein, z.B. durch ein Senkerodierverfahren oder mittels eines Lasers, wenn der Düsenträger aus Metall besteht, oder beispielsweise durch Einformen, wenn der Düsenträger aus Kunststoff, insbesondere aus Polyurethan, Polyethylen oder Silikon besteht. Alternativ können die Flüssigkeitseinspritrdüsen in Gestalt separater, vom Düsenträger getragener Einsätze ausgebildet sein. Bei einer solchen Ausführungsform ist vorzugsweise der Düsenträger aus Metall, insbesondere aus nicht rostendem Edelstahl ausgeführt, und die Einsätze bestehen aus einem Kunststoff, insbesondere aus Polyurethan, Polyethylen oder Silikon. Die Einsätze können jedoch ebenfalls aus Metall bestehen. Jeder Einsatz umfasst vorzugsweise mehrere Flüssigkeitseinspritrdüsen, wobei gemäß einer Ausführungsform die Flüssigkeitseinspritrdüsen eines Einsatzes jeweils den gleichen Einspritzwinkel aufweisen. Es ist dabei vorteilhaft, wenn die Einsätze so ausgebildet sind, dass sie in zwei Stellungen, die sich um 180° voneinander unterscheiden in den Düsenträger einsetzbar sind. Es können dann mit gleich ausgeführten Einsätzen zwei unterschiedliche Einspritzwinkel realisiert werden, indem ein Einsatz in der einen Stellung und ein weiterer Einsatz in der anderen Stellung in den Düsenträger eingesetzt wird.According to the invention, the liquid injection nozzles can be formed in the nozzle carrier itself be, for example by a die-sinking EDM method or by means of a laser if the nozzle holder is made of metal, or for example by molding if the nozzle holder is made of plastic, in particular polyurethane, polyethylene or silicone. Alternatively, the liquid injection nozzles can be designed in the form of separate inserts carried by the nozzle carrier. In such an embodiment, the nozzle carrier is preferably made of metal, in particular stainless steel, and the inserts consist of a plastic, in particular polyurethane, polyethylene or silicone. However, the inserts can also be made of metal. Each insert preferably comprises a plurality of liquid injection nozzles, wherein according to one embodiment the liquid injection nozzles of an insert each have the same injection angle. It is advantageous if the inserts are designed in such a way that they can be inserted into the nozzle holder in two positions that differ from one another by 180 °. It is then possible to implement two different injection angles with inserts of the same design, by inserting one insert in one position and a further insert in the other position in the nozzle holder.
Unabhängig davon, ob die Flüssigkeitseinspritrdüsen in dem Düsenträger selbst oder in vom Düsenträger getragenen Einsätzen ausgebildet sind, versorgt vorzugsweise eine gemeinsame Speiseleitung alle einem Düsenträger zugeordneten Flüssigkeitseinspritrdüsen mit Flüssigkeit. Auf diese Weise ist die Zahl der außen an der Mörtelmischpumpen vorzunehmenden Anschlüsse deutlich reduziert. Bei einer solchen Ausführungsform ist vorzugsweise zwischen das Ende der Speiseleitung und den Düsenträger ein Verteilerelement geschaltet, das die Zuführung von Flüssigkeit aus der Speiseleitung zu den einzelnen Flüssigkeitseinspritrdüsen übernimmt. Dieses Verteilerelement kann beispielsweise ein Kunststoffformteil sein, dessen Material so gewählt ist, dass es zugleich für eine Abdichtung zwischen der Speiseleitung und der Außenseite der Mischkammer sorgt.Regardless of whether the liquid injectors in the Nozzle holder itself or in carried by the nozzle holder inserts are formed, preferably supplies a common feed line all assigned to a nozzle holder Liquid injection nozzles with Liquid. In this way, the number of mortar pumps to be carried out on the outside connections significantly reduced. In such an embodiment is preferred a distributor element is connected between the end of the feed line and the nozzle carrier, that's the feed of liquid from the feed line to the individual liquid injection nozzles. This distributor element can, for example, be a molded plastic part be, its material chosen so is that it is for a seal between the feed line and the outside the mixing chamber.
Zur weiteren Verbesserung der Betriebssicherheit ist bei bevorzugten Ausführungsformen der erfindungsgemäßen Mörtelmischpumpe auch die Förderschnecke mit einer Ummantelung aus Polyurethan, Polyethylen oder Silikon versehen. Die Ausführung kann dabei so sein, dass die Förderschnecke lediglich eine innere Welle aus Stahl aufweist und die einzelnen Schneckengänge vollständig aus Polyurethan, Polyethylen oder Silikon gebildet sind.To further improve operational safety is in preferred embodiments the mortar mixing pump according to the invention also the screw conveyor with a coating of polyurethane, polyethylene or silicone Mistake. Execution can be such that the screw conveyor only has an inner shaft made of steel and the individual worm gears completely Polyurethane, polyethylene or silicone are formed.
Damit auch am mischkammerfernen Ende der Förderschnecke Ablagerungen weitgehend verhindert sind, ist vorzugsweise ein dem mischkammerfernen Ende der Förderschnecke benachbarter Motorflansch auf seiner dem Trichter zugewandten Seite mit einer Verkleidung aus Polyurethan, Polyethylen oder Silikon versehen. Diese Verkleidung weist gemäß einer bevorzugten Ausgestaltung eine angeformte Dichtlippe zur Abdichtung gegenüber einer die Förderschnecke antreibenden Welle auf.This means that even at the end of the Auger Deposits are largely prevented, is preferably a End of the screw conveyor remote from the mixing chamber Adjacent motor flange on its side facing the funnel with a covering made of polyurethane, polyethylene or silicone Mistake. According to a preferred embodiment, this covering has an integrally formed sealing lip for sealing against the screw conveyor driving shaft.
