Abstract
Description
Die Erfindung betrifft einen dynamischen Mischer für strukturviskose Pasten, insbesondere für Dentalmaterialien verschiedenster Konsistenzen.The The invention relates to a dynamic mixer for pseudoplastic pastes, in particular for dental materials different consistencies.
Insbesondere
im Dentalbereich werden chemisch härtende Pasten in Doppelkartuschen
oder Schlauchbeuteln angeboten, die vom Anwender mittels Gerät zugleich
dosiert, gefördert
und angemischt werden. Die Mischung wird dabei von Mischaufsätzen, z.B.
dynamischen Mischern, übernommen,
die mit den Doppelkartuschen oder Schlauchbeuteln verbunden werden.
Beispiele solcher Mischer sind z.B. in
Da für unterschiedliche Anwendungen auch sehr verschiedene Konsistenzen zum Einsatz kommen, besteht ein Bedarf, einen Mischaufsatz zu entwickeln, der für all diese Konsistenzen universell einzusetzen ist. Aufgabe der Erfindung ist die Bereitstellung eines solchen Mischaufsatzes bzw. dynamischen Mischers.There for different Applications also very different consistencies are used There is a need to develop a mixing attachment for all of these Consistencies universal use is. The object of the invention is the provision of such a Mischaufsatzes or dynamic Mixer.
Bei niedrigviskosen Konsistenzen erhält man durch hohe Scherung in engen Spalten die beste Vermischung. Durch zunehmende Verwendung dieser Mischgeräte auch für hochviskose Pasten wurde es notwendig, Mischeraufsätze zu konstruieren, die mit größeren Strömungsquerschnitten ausgestattet sind, da es sonst bei den hochviskosen Konsistenzen zu unerwünscht hohen Förderkräften und unerwünschter Erwärmung des Mischgutes kommt.at low viscosity consistencies by high shear in narrow gaps the best mixing. Due to increasing use of these mixers even for high viscosity pastes has been it necessary, mixer attachments to construct those with larger flow cross sections otherwise it is with the high-viscosity consistencies too undesirable high production and undesirable warming of the mix comes.
Bei den niedrigviskosen, und insbesondere bei den strukturviskosen Pasten mit ausgeprägten Fließgrenzen, kommt es durch diese erweiterten Strömungsquerschnitte dazu, dass nur im Bereich der Oberflächen von Rotor und Stator zu einer Vermischung der Komponenten stattfindet. In Bereichen größerer Schichtstärke kommt es dann zur Pfropfenströmung. Dadurch werden schlecht, oder sogar ungemischte Pastenanteile aus dem Mischer ausgefördert.at the low viscosity, and especially with the pseudoplastic pastes with pronounced yield stress, it comes through these extended flow cross sections that only in the area of the surfaces Rotor and stator to a mixing of the components takes place. In areas of greater thickness comes it then to the plug flow. As a result, poor, or even unmixed paste portions are made carried out the mixer.
Bei Mischern, deren Flügel weitestgehend bis an die Wand der Mischkammer reichen, ist im Außenbereich der Mischkammer durch die dort auftretende hohe Umfangsgeschwindigkeit eine gute Mischwirkung gegeben. In der Schicht, zwischen der Mischerwelle und diesem Außenbereich kann die geförderte Paste jedoch wie ein Pfropfen zusammen mit dem Mischerinnenteil rotieren, wenn keine Strömstörer vorhanden sind.at Mixers whose wings extend as far as possible to the wall of the mixing chamber, is outdoors the mixing chamber by the occurring there high circumferential speed given a good mixing effect. In the layer, between the mixer shaft and this outdoor area can the sponsored Paste, however, like a graft along with the mixer interior rotate if there are no perturbations are.
Die im Apparatebau üblichen Strömstörer sind an den Rohr- oder Kesselaußenwänden installiert. Bei den im Vorliegenden betrachteten dynamischen Mischern handelt es sich um Spritzgussteile aus Kunststoff für Einmalanwendungen, die aus möglichst wenigen Teilen bestehen sollen und einfach herzustellen sein sollen. Ein Stromstörer an der Wandung des Mischergehäuses ist mit einfachen Spritzgussformen nicht herzustellen.The usual in apparatus construction Are disturbers installed on the pipe or boiler outer walls. The dynamic mixers considered herein are These are plastic injection molded parts for single use, made as possible few parts and should be easy to produce. A baffle on the wall of the mixer housing can not be produced with simple injection molds.
Als einfach zu gestaltende Stromstörer haben sich um die Mischwelle umlaufende Erweiterungen des Wellendurchmessers erwiesen. Diese von der Mischwelle radial in den Mischraum ragende Durchmessererweiterungen verringern an dieser Stelle den Strömungsquerschnitt, zwingen somit die Paste aus der Propfenströmung heraus und erhöhen kurzzeitig an dieser Stelle die Strömungsgeschwindigkeit und somit die Scherung.When easy to design baffles have around the mixing shaft encircling extensions of the shaft diameter proved. These diametrically extending from the mixing shaft in the mixing chamber diameter expansions reduce the flow cross-section at this point, thus force the paste from the plug flow out and increase for a short time at this point the flow velocity and thus the shear.
Die Aufgabe wird somit durch einen dynamischen Mischer gemäß einem der Anspruch 1, 5 und 9 gelöst.The Task is thus by a dynamic mixer according to a the claim 1, 5 and 9 solved.
In einer Ausführungsform weist der dynamische Mischer ein zumindest teilweise weitestgehend zylindrisches Kammerteil und eine Mischerwelle auf,
- – mit einer Ausbringöffnung am vorderen Ende des Kammerteils,
- – mit einem am hinteren Ende des Kammerteils angeordneten Verschlussteil mit Eintrittsöffnungen für einzubringende Einzelkomponenten,
- – sowie einer zentrischen Öffnung für die im Kammerteil um seine und ihre Längsachse drehbare Mischerwelle, an der sich in mindestens zwei axial hintereinander angeordneten scheibenförmigen Mischflügelebenen jeweils mindestens zwei radial hintereinander angeordnete Mischflügel befinden,
- – und der Besonderheit, dass mindestens ein Teil der zwischen den Mischflügelebenen befindlichen Mischachse eine den Strömungsquerschnitt verengende Aufweitung der Mischachse besitzt.
- With a discharge opening at the front end of the chamber part,
- With a closure part arranged at the rear end of the chamber part and having inlet openings for individual components to be introduced,
- - And a central opening for the rotatable in the chamber part about its and its longitudinal axis mixer shaft at which at least two axially successively arranged disk-shaped mixing blade planes are each at least two radially successively arranged mixing blades,
- - And the special feature that at least a part of the mixing axis located between the mixing axis has a narrowing the flow cross-section widening of the mixing axis.
Die Aufweitung ist allgemein so gestaltet, dass die Mischerachse an der betreffenden Stelle nach außen von der zylindrischen Form abweicht. Die Aufweitung kann dabei z.B. eine Wölbung sein oder keilförmig aus der Mischachse heraustreten, so dass der Querschnitt der Auf weitung eine eckige oder runde Querschnittsform besitzt. Die dem Kammerteil entgegenragende Seite der Aufweitung kann abgeschrägt oder gerundet sein.The Expansion is generally designed so that the mixer axis the body concerned to the outside deviates from the cylindrical shape. The expansion may be e.g. a vault be or wedge-shaped emerge from the mixing axis, so that the cross section of the expansion on has an angular or round cross-sectional shape. The chamber part opposite side of the widening may be beveled or be rounded.
Die Aufweitung kann auch so gestaltet sein, dass die Mischerachse an der betreffenden Stelle so von der zylindrischen Form abweicht, dass ein halb sphärischer und halb elliptischer Gesamtquerschnitt entsteht.The Expansion can also be designed so that the mixer axis the position in question differs from the cylindrical shape, that a half-spherical and semi-elliptical overall cross-section arises.
Sämtliche Abweichungen von der Zylinderform können auch entlang der Mischachse versetzt angeordnet sein, so dass verschiedene Mischebenen verschieden angeordnete oder geformte Abweichungen aufweisen können.All deviations from the cylinder Shape can also be arranged offset along the mixing axis, so that different mixing levels may have differently arranged or shaped deviations.
Eine weitere Möglichkeit, die Propfenströmung zu vermeiden, ist es, die Mischwelle auf den nicht mit Mischflügeln besetzten Ebenen exzentrisch zur Rotationsachse zu gestalten. Dies wird z.B. erreicht, wenn die Welle mit ovalem Querschnitt geformt ist. Ähnlich einer Nockenwelle kann die Welle aber auch abschnittsweise kreis- bzw. scheibenförmig gestaltet sein und zueinander versetzt exzentrisch angeordnete Ebenen besitzen. Bei exzentrischer versetzter Anordnung der Ebenen können diese aber auch vieleckig gestaltet sein.A another possibility the plug flow To avoid, it is the mixing shaft on the not mixed with mixing blades To make planes eccentric to the axis of rotation. This is e.g. achieved when the shaft is formed with an oval cross-section. Similar to one Cam shaft, the shaft but also partially circular or disc-shaped be designed and mutually offset eccentrically arranged levels have. In eccentric staggered arrangement of the levels, these can but also be designed polygonal.
Die oben beschrieben erwähnten Stromstörer sind Teil des Rotors und somit als Umlenkung des axialen Produktförderstroms zu verstehen.The mentioned above baffles are part of the rotor and thus as a deflection of the axial product flow to understand.
Ein wichtiger Bereich für die Mischwirkung bei reaktiven Komponenten ist der Bereich, in dem diese erstmalig aufeinander treffen. Verweilen hier ungemischte Schichten aneinander, kann das zu unerwünschten Spontanreaktionen führen.One important area for the mixing effect of reactive components is the area in which these meet each other for the first time. Linger here unmixed layers to each other, this can be too undesirable Lead to spontaneous reactions.
Daher haben sich besonders in diesem Bereich Strömstörer als vorteilhaft erwiesen.Therefore Particularly in this area, flow disruptors have proven to be advantageous.
Umgesetzt wird das z.B., indem die zum Mischen vorteilhafte hohe Umfangsgeschwindigkeit des äußeren Bereichs durch weitestgehend bis an die Gehäusewand und den Verschlussteilboden reichende Mischflügel erzielt wird. Im Übergangsbereich von Verschlussteil und Mischwelle spart man vorteilhaft die Mischflügel ganz aus, und ordnet einen oder mehrere Stromstörer am Verschlussteilboden an.implemented This is achieved, for example, by the high circumferential peripheral speed of the outer region which is advantageous for mixing by as far as possible to the housing wall and the closure part bottom reaching mixing blades is achieved. In the transition area Of closure part and mixing shaft advantageous to save the mixing blades completely and assigns one or more baffles to the bottom of the closure.
Werden diese Stromstörer des Verschlussteils block-, keil- oder rampenförmig teilumlaufend um die Mischwelle angeordnet, können sie im Zusammenspiel mit den den Eingangsöffnungen zugewandten Mischflügeln nach Beendigung des Mischvorganges einen direkten Produktstrom der Komponenten in die Einlassöffnung der anderen Komponente verhindern.Become these baffles of the closure part block-, wedge- or ramp-shaped partly circulating around the mixing shaft arranged, can they in conjunction with the input ports facing mixing blades after Completion of the mixing process a direct product flow of the components in the inlet opening prevent the other component.
