Description
Die vorliegende Erfindung betrifft ein Mischwerkzeug für einen Mischer gemäß dem Oberbegriff des Anspruchs 1 sowie einen Mischer gemäß dem Oberbegriff des Anspruchs 10.The present invention relates to a mixing tool for a mixer according to the preamble of claim 1 and to a mixer according to the preamble of
Ein gattungsgemäßes Mischwerkzeug sowie ein gattungsgemäßer Mischer sind beispielsweise aus der
Üblicherweise wird bei derartigen Mischern ein mit Mischgut gefüllter Mischbehälter durch einen Mischerkopf verschlossen. Der Mischerkopf weist dabei das Mischwerkzeug auf.Usually, in such mixers, a mixing container filled with mix is closed by a mixer head. The mixer head has the mixing tool.
Nach dem Verschließen des Mischbehälters mit dem Mischerkopf wird der geschlossene Mischbehälter um eine horizontale Achse um 180° gedreht, so dass das Mischwerkzeug nun oberhalb des Bodens des Mischerkopfes angeordnet ist.After closing the mixing container with the mixer head of the closed mixing container is rotated about a horizontal axis by 180 °, so that the mixing tool is now located above the bottom of the mixer head.
Danach erfolgt der eigentliche Mischprozess, bei dem sich das Mischwerkzeug üblicherweise um eine vertikale Achse in dem Mischbehälter dreht.Thereafter, the actual mixing process takes place, in which the mixing tool usually rotates about a vertical axis in the mixing container.
Der oben beschriebene aus dem Stand der Technik benannte Mischer hat sich in der Praxis an sich bewährt.The above-described prior art mixer has proven itself in practice.
Als problematisch bei diesem oder anderen aus dem Stand der Technik bekannten Mischern und den darin eingesetzten Mischwerkzeugen ist nach wie vor eine relativ hoher Temperatureintrag, bewirkt durch die Durchmischung des Mischgutes mit den sich drehenden Werkzeugflügeln des Mischwerkzeugs.As problematic in this or other known from the prior art mixers and the mixing tools used therein is still a relatively high temperature entry, caused by the mixing of the mix with the rotating blades of the tool mixing tool.
Problematisch sind außerdem während des Durchmischens des Mischgutes entstehende Ablagerungen an der Seiteninnenwand sowie dem Boden des Mischerkopfes unterhalb des Mischwerkzeugs, zu deren Vermeidung eine hohe Rotationsgeschwindigkeit erforderlich ist, welche allerdings den Nachteil hoher Temperatureinträge in das Mischgut hat.Also problematic during the mixing of the mix resulting deposits on the side inner wall and the bottom of the mixer head below the mixing tool, to avoid a high rotational speed is required, which, however, has the disadvantage of high temperature entries in the mix.
Auch eine Heranführung der Werkzeugflügel nahe an die Seiteninnenwand oder nahe zum Boden geht mit einer Erhöhung der Leistungsaufnahme des Mischers und hoher Temperatureinträge in das Mischgut einher.An approach of the tool wings close to the side inner wall or near the bottom is accompanied by an increase in the power consumption of the mixer and high temperature entries in the mix.
Aufgabe der vorliegenden Erfindung ist es, ein Mischwerkzeug für einen Mischer bereitzustellen, mit dem eine qualitativ gute Durchmischung bei geringen Temperatureinträgen und geringer Leistungsaufnahme sowie Reduzierung verbleibender Ablagerungen ermöglicht ist.Object of the present invention is to provide a mixing tool for a mixer, with a good quality mixing at low temperature inputs and low power consumption and reduction of remaining deposits is possible.
Weitere Aufgabe der Erfindung ist es, einen Mischer mit geringer Leistungsaufnahme bereitzustellen, der überdies einfacher zu reinigen ist.Another object of the invention is to provide a mixer with low power consumption, which is also easier to clean.
Die erste Aufgabe wird durch ein Mischwerkzeug mit den Merkmalen des Anspruchs 1 gelöst.The first object is achieved by a mixing tool having the features of claim 1.
Die zweite Aufgabe wird durch einen Mischer mit den Merkmalen des Anspruchs 10 gelöst.The second object is achieved by a mixer with the features of
Vorteilhafte Ausführungsvarianten sind in den Unteransprüchen angegeben.Advantageous embodiments are specified in the subclaims.
Das erfindungsgemäße Mischwerkzeug für einen Mischer, insbesondere einen Containermischer, weist eine Nabe auf, an der wenigstens zwei radial oder annähernd radial zu einer Drehachse der Nabe vorstehende Flügel angeordnet sind.The mixing tool according to the invention for a mixer, in particular a container mixer, has a hub on which at least two radially or approximately radially to a rotational axis of the hub protruding wings are arranged.
Die Flügel sind derart geformt, dass deren maximale Dicke in einem, in Rotationsrichtung der Nabe betrachtet, vorderem Abschnitt der Flügel liegt.The vanes are shaped so that their maximum thickness lies in a forward portion of the vanes, viewed in the direction of rotation of the hub.
Wie sich überraschend gezeigt hat, ist bei einer derartigen Ausrichtung der Flügel eine gegenüber Mischwerkzeugen mit beispielsweise keilförmigen Mischflügeln, die an ihrer in Laufrichtung betrachteten Vorderkante ihre minimale Dicke haben, eine verbesserte Durchmischung des Mischguts erreichen.As has surprisingly been found in such an orientation of the wing is compared to mixing tools with, for example, wedge-shaped mixing blades, which have their minimum thickness at their considered in the direction of the front edge their minimum thickness, achieve improved mixing of the mix.
Die Flügel sind gemäß einer bevorzugten Ausführungsvariante tragflächenförmig geformt, mit einer konvex geformten Oberseite mit im Wesentlichen in Drehrichtung der Nabe nach hinten abnehmender Krümmung sowie einer Unterseite, die von einem konvex gekrümmten, in Drehrichtung der Nabe vorderen Abschnitt stetig in einen konkav gekrümmten hinteren Abschnitt übergeht.The wings are in accordance with a preferred embodiment, an airfoil-shaped, with a convex shaped top with substantially in the direction of rotation of the hub rearwardly decreasing curvature and a bottom, which merges continuously from a convex curved, in the direction of rotation of the hub portion in a concave curved rear portion ,
Die tragflächenförmige Gestalt der Flügel eines solchen Mischwerkzeugs ist in vielerlei Hinsicht vorteilhaft.The wing-like shape of the wings of such a mixing tool is advantageous in many respects.
So kann ein solches Mischwerkzeug aufgrund der durch die Bewegung der Flügel hervorgerufenen verbesserten Auftriebswirkung auf das Mischgut und den geringen Luftwiderstand eines derart geformten Flügels bei vergleichsweise niedriger Laufgeschwindigkeit eine gute Durchmischung des Mischguts erreichen.Thus, due to the improved buoyancy effect on the mix caused by the movement of the vanes and the low air resistance of such a molded wing, such a mixing tool can achieve good thorough mixing of the mix at a comparatively low running speed.
Solche Flügel können in einem ausreichend großen Abstand vom Boden des Mischerkopfes beabstandet positioniert werden, so dass auch für eine Reinigung des Mischwerkzeuges und des Mischers eine Demontage des Mischwerkzeugs nicht notwendig ist, was mit einer großen Zeitersparnis einhergeht.Such wings can be positioned at a sufficiently large distance from the bottom of the mixer head, so that even for a cleaning of the mixing tool and the mixer disassembly of the mixing tool is not necessary, which is associated with a large time savings.
In einer vorteilhaften Ausführungsvariante weisen die freien Enden der Flügel jeweils einen winklig zum jeweiligen Flügel ausgerichteten Außenflügel auf.In an advantageous embodiment, the free ends of the wings each have an angle to the respective wing aligned outer wing.
Durch einen solchen Außenflügel wird die Verwirbelung des Mischgutes bei der Rotation des Mischwerkzeugs reduziert, so dass dadurch eine Laminarströmung begünstigt wird, mit der das Mischgutes durchmischt wird, was zur Vermeidung von Ablagerungen am Mischwerkzeug und der Seitenwand des Mischers beiträgt.By such an outer wing, the turbulence of the mixed material is reduced during the rotation of the mixing tool, so that thereby a laminar flow is favored, with which the mixed material is mixed, which contributes to the avoidance of deposits on the mixing tool and the side wall of the mixer.
Die Außenflügel sind dabei bevorzugt keilförmig ausgebildet, mit einer konvex geformten Frontfläche.The outer wings are preferably wedge-shaped, with a convex front surface.
Insbesondere sind die Außenflügel länglich zur Drehachse der Nabe gekippt ausgerichtet.In particular, the outer wings are aligned obliquely tilted to the axis of rotation of the hub.
Zur einfachen Herstellung eines solchen Mischwerkzeugs sind die Außenflügel am freien Ende der Flügel bevorzugt montiert. Denkbar ist auch eine einstückige Anformung der Außenflügel am freien Ende der Flügel. Ebenso bevorzugt sind die Flügel an der Nabe montiert.For easy production of such a mixing tool, the outer wings are preferably mounted at the free end of the wing. Also conceivable is a one-piece molding of the outer wing at the free end of the wing. Also preferably, the wings are mounted on the hub.
Bei dem erfindungsgemäßen Mischer ist nach einer bevorzugten Ausführungsvariante die Spannweite der Flügel des Mischwerkzeugs derart bemessen, dass der Abstand eines radial äußeren Randes der Flügel von der Seiteninnenwand des Mischerkopfes zwischen 5 % und 60 % der Spannweite der Flügel beträgt.In the mixer according to the invention, according to a preferred embodiment, the span of the blades of the mixing tool is dimensioned such that the distance of a radially outer edge of the wings from the side inner wall of the mixer head is between 5% and 60% of the wingspan.
Insbesondere größere Abstände der äußeren Ränder der Flügel von der Seiteninnenwand sind dabei für die Reinigung des Mischbehälters von Vorteil.In particular, greater distances between the outer edges of the wings of the side inner wall are advantageous for the cleaning of the mixing container.
Durch die tragflächenförmige Gestaltung der Flügel ist trotz eines relativ großen Abstandes der Flügel von der Seiteninnenwand des Mischerkopfes oder des Mischbehälters eine hinreichende Sogwirkung einerseits für die Durchmischung des Mischguts und zum zweiten zur Verhinderung von Ablagerungen an der Seiteninnenwand gewährleistet.Due to the wing-shaped design of the wings despite a relatively large distance of the wing from the side inner wall of the mixer head or the mixing container sufficient suction on the one hand for the mixing of the mix and the second to prevent deposits on the side inner wall.
Bevorzugt beträgt auch der Abstand der Unterseite der Flügel vom Boden des Mischerkopfes zwischen 1 % und 35 % der Spannweite der Flügel.Preferably, the distance between the underside of the wings from the bottom of the mixer head is between 1% and 35% of the wingspan.
Auch hier sind insbesondere größere Abstände der Flügel vom Boden des Mischerkopfes für die Reinigung des Mischers von besonderem Vorteil.Again, in particular larger distances of the wings from the bottom of the mixer head for the cleaning of the mixer are of particular advantage.
Der Übergang zwischen dem Boden und der Seiteninnenwand ist nach einer bevorzugten Ausführungsvariante stetig, insbesondere als Kreisumfangsabschnitt ausgebildet, was für einen zusätzlichen Auftrieb des Mischgutes bei Rotation des Mischwerkzeugs sorgt.The transition between the bottom and the side inner wall is continuous according to a preferred embodiment, in particular formed as a circular peripheral portion, which provides for an additional buoyancy of the mixed material upon rotation of the mixing tool.
Denkbar ist auch, den Übergang zwischen Boden und der Seiteninnenwand unstetig als Winkel, insbesondere als rechten Winkel auszubilden.It is also conceivable, discontinuously form the transition between the bottom and the inner side wall as an angle, in particular as a right angle.
Durch die tragflächenförmige Gestaltung der Flügel ist auch bei einer solchen Geometrie nach wie vor eine hinreichende Durchmischung des Mischgutes, bedingt durch die hinreichend große Auftriebskraft, erzeugt durch die tragflächenförmigem Flügel, ermöglicht.Due to the airfoil-shaped design of the wings, even with such a geometry, a thorough mixing of the mixed material, due to the sufficiently large buoyancy force generated by the wing-shaped wing, is still possible.
Diese ermöglicht insbesondere auch eine besonders kostengünstige Herstellung eines Mischerkopfes, bei dem der Boden als ebene, kreisscheibenförmige Platte ausgebildet sein kann, an die sich eine umfängliche Seitenwand als Teil des auf den Mischerkopf aufsetzbaren Mischbehälters anschließen kann.This allows in particular a particularly cost-effective production of a mixer head, in which the bottom can be formed as a flat, circular disk-shaped plate, which can be followed by a peripheral side wall as part of the mixer head can be placed on the mixing container.

Die Spannweite der Flügel 5 ist bevorzugt derart bemessen, dass der Abstand eines radial äußeren Randes der Flügel 5 von der Seiteninnenwand 22 des Mischerkopfes 2 zwischen 5 % und 60 % der Spannweite I der Flügel 5 beträgt.The span of the
Ein solcher Abstand ermöglicht einerseits eine hinreichende Durchmischung des Mischgutes, hervorgerufen durch die Sogwirkung des rotierenden Mischwerkzeugs 3.On the one hand, such a distance enables a sufficient thorough mixing of the mixed material, caused by the suction effect of the
Zum zweiten ist durch die Beabstandung der Flügel 5 bzw. der Außenflügel 6 von der Seiteninnenwand 22 des Mischerkopfes 2 eine Reinigung des Mischerkopfes 2 bei eingebautem Mischwerkzeug 3 ermöglicht, ohne dies demontieren zu müssen.Second, by the spacing of the
