Description

Die vorliegende Erfindung betrifft ein Statikmischelement zum Mischen fliessfähiger Mehrkomponenten-Massen, wie z. B. mehrkomponentiger Reaktionsmörtel, der im Oberbegriff von Patentanspruch 1 genannten Art. Derartige Statikmischelemente werden an den Ausgabeöffnungen von Ausgabevorrichtungen für derartige Mehrkomponenten-Massen angeordnet, wo Sie die Komponenten der Massen miteinander vermischen, wenn diese das Statikmischelement durchströmen.The present invention relates to a static mixing element for mixing flowable multicomponent masses such. B. multicomponent reaction mortar referred to in the preamble of claim 1. Such static mixing elements are arranged at the output openings of dispensers for such multi-component masses, where you mix the components of the masses when they flow through the static mixing element.

Aus der DE 42 16 393 A1 ist ein Mischer aus Kunststoffspritzguss mit zylindrischer Innenkontur und darin angeformten, schräg angeordneten Stegen bekannt, die Verzweigungen und Zusammenführungen für die Komponentenmischung bilden. Der Mischer weist zwei Teile auf, die über ein Filmscharnier miteinander klappbeweglich verbunden sind. In der zusammengeklappten Stellung werden beide Teile über einen Schnappverschluss zusammengehalten. Die Stege sind dabei in beiden Teilen des Mischers ausgebildet.From the DE 42 16 393 A1 is known a plastic injection molding mixer with a cylindrical inner contour and formed therein, obliquely arranged webs, which form branches and mergers for the component mixture. The mixer has two parts which are hingedly connected to each other via a film hinge. In the folded position, both parts are held together by a snap closure. The webs are formed in both parts of the mixer.

Das Versehen beider Teile des Mischers mit Stegen bedingt eine entsprechende Ausbildung der Spritzgusswerkzeuge. Für beide Teile muss dort eine entsprechende Negativform vorgesehen werden, was die Werkzeuge teuer macht.The provision of both parts of the mixer with webs requires a corresponding design of the injection molding tools. For both parts there must be provided a corresponding negative mold, which makes the tools expensive.

Aus der CH 600 937 ist eine Mischvorrichtung zum kontinuierlichen Mischen von Mehrkomponenten-Materialien mit in Durchströmrichtung aufeinanderfolgenden säulenförmig angeordneten Mischelementen bekannt. Die Mischelemente bestehen dabei aus zwei Teilen, die über Scharniere miteinander klappbeweglich verbunden sind. In den Mischelementen sind dabei Strömungskanäle und Mischkammern angeordnet, die für eine Vermischung von durch die Mischelemente strömendem Material sorgen. Beide Teile der Mischelemente für sich weisen dabei Teile der Strömungskanäle und der Mischkammern auf.From the CH 600 937 is a mixing device for continuously mixing multi-component materials with successively in the flow direction of columnar mixing elements known. The mixing elements consist of two parts, which are hingedly connected to each other by hinges. In the mixing elements while flow channels and mixing chambers are arranged, which ensure a mixing of material flowing through the mixing elements. Both parts of the mixing elements in this case have parts of the flow channels and the mixing chambers.

Auch hier bedingt das Versehen beider Teile der Mischelemente mit Teilen der Strömungskanäle und Mischkammern eine entsprechende Ausbildung der Spritzgusswerkzeuge. Für beide Teile muss dort eine entsprechende Negativform vorgesehen werden, was die Werkzeuge teuer macht.Again, the condition of both parts of the mixing elements with parts of the flow channels and mixing chambers requires a corresponding design of the injection molds. For Both parts must be provided there a corresponding negative mold, which makes the tools expensive.

Aus der US 2002/0001257 A1 ist ein Mischelement mit einem radial geteilten Mischkanal bekannt, in dem Elemente mit mehreren Mischfahnen angeordnet sind. Die Mischfahnen sind als massive Körper ausgebildet, die sich zu ihrer freien Kante hin verjüngen.From the US 2002/0001257 A1 is a mixing element with a radially divided mixing channel is known in which elements are arranged with a plurality of mixing vanes. The mixing vanes are designed as massive bodies that taper towards their free edge.

Aus der US 6 109 781 ist ferner ein Mischelement bekannt, das aus mehreren miteinander verbundenen Elementen besteht, wobei jedes Element einen zylindrischen Körper umfasst, der aus zwei Halbschalen gebildet ist. Die hohlen zylindrischen Körper weisen dabei an sich gegenüberliegenden Innenseiten jeweils nach innen ragende Platten auf.From the US Pat. No. 6,109,781 Further, a mixing element is known, which consists of a plurality of interconnected elements, each element comprising a cylindrical body, which is formed of two half-shells. The hollow cylindrical body have in each case on opposite inner sides in each case inwardly projecting plates.

Die Aufgabe der vorliegenden Erfindung liegt daher darin, ein Mischelement der vorgenannten Art zu entwickeln, das die vorgenannten Nachteile vermeidet. Dieses wird erfindungsgemäss durch die in Anspruch 1 genannten Massnahmen erreicht.The object of the present invention is therefore to develop a mixing element of the aforementioned type, which avoids the aforementioned disadvantages. This is achieved according to the invention by the measures mentioned in claim 1.

Demnach sind die Fahnenelemente wenigstens bereichsweise hohl ausgebildet und ist der Hohlraum zur Aussenfläche des Schalenteils hin offen, wodurch eine Herstellung des Statikmischelements erreicht wird. Dazu können am Formwerkzeug einer Spritzgussmaschine entsprechende Vorsprünge, vorgesehen sein. Die Basis der Fahnenelemente Körper kann dabei konisch bis wulstartig verbreitert sein, wodurch günstige Fliessübergänge und gleichmässige Wandstärken erreicht werden. Durch die möglichen weicheren Fliessübergänge besteht im Statikmischelement ein geringeres Tot- bzw. Verlustvolumen, da tote Ecken nicht mit zu mischender Masse bzw. Mischgut ausgefüllt werden müssen. Die Fahnenelemente ragen dadurch beim zusammengeklappten Statikmischelement in das jeweils gegenüberliegende zweite Schalenteil hinein, so dass dort an gegenüberliegender Stelle kein weiteres Fahnenelement angeformt werden muss. Die Fahnenelemente weisen dabei einen planaren Habitus auf und bilden wenigstens zwei ebene, quer zur Strömungsrichtung liegende Flächenseiten aus. Der freigelassene Abschnitt im Durchflussraum dient dem Vorbeiströmen einer zu mischenden Masse an einem Fahnenelement. Aufgrund des Übergreifens der Fahnenelemente von einem Schalenteil ins andere werden nun insgesamt weniger Strömungsleitelemente bzw. Fahnenelemente benötigt, wodurch die Werkzeugkosten gesenkt werden können. Besonders günstig ist es daher, wenn die Fahnenelemente an nur einem Schalenteil ausgebildet sind.Accordingly, the flag elements are at least partially hollow and the cavity is open to the outer surface of the shell part, whereby a preparation of the static mixing element is achieved. For this purpose, corresponding projections can be provided on the mold of an injection molding machine. The base of the flag elements body can be widened conically to bead-like, whereby favorable flow transitions and uniform wall thicknesses can be achieved. Due to the possible softer flow transitions there is a smaller dead or loss volume in the static mixing element, since dead corners do not have to be filled with mass or mixture to be mixed. As a result, the flag elements protrude into the opposing second shell part when the static mixing element is folded, so that no further flag element has to be formed there at the opposite location. The flag elements in this case have a planar habit and form at least two planar surface sides lying transversely to the direction of flow. The released section in the flow space serves to flow past a mass to be mixed on a flag element. Due to the overlapping of the flag elements from one shell part to the other now less total flow guide elements or flag elements are needed, whereby the tool costs can be reduced. It is therefore particularly advantageous if the flag elements are formed on only one shell part.

Vorteilhaft weisen die Fahnenelemente jeweils eine freie Stirnfläche auf, deren Kontur der Innenkontur des anderen Schalenteils angepasst ist. Dadurch können die Fahnenelemente, bei entsprechender Höhe über den Dichtkanten, im zusammengeklappten Zustand des Statikmischelementes formschlüssig bis an die Innenwand des zweiten Schalenteils herangeführt sein. Es können ferner Fahnenelemente nicht ganz bis an das gegenüberliegende Schalenteil herangeführt sein, so dass ein Wechsel der Mischebene möglich ist.Advantageously, the flag elements each have a free end face whose contour is adapted to the inner contour of the other shell part. As a result, the flag elements, with a corresponding height above the sealing edges, in the folded state of the static mixing element can be positively brought up to the inner wall of the second shell part. Furthermore, flag elements can not be brought completely to the opposite shell part, so that a change of the mixing plane is possible.

Günstig ist es ferner, wenn an der Stirnfläche wenigstens eines Fahnenelementes ein als Rastelement ausgebildetes Verbindungsmittel angeordnet ist, das mit einem Gegenrastmittel an dem anderen Schalenteil in Wirkverbindung bringbar ist. Durch diese Massnahme brauchen keine Haltedome mehr vorgesehen zu werden, die die Werkzeugkosten erhöhen würden. Das Statikmischelement kann daher ausserdem kürzer gebaut werden, da auch der Platz für diese Dome eingespart werden kann.It is also favorable if, arranged on the end face of at least one flag element as a locking element connecting means is arranged, which is engageable with a counter-locking means on the other shell part in operative connection. By this measure no holding domes need to be provided, which would increase the tooling costs. The static mixing element can therefore also be built shorter, since the space for these dome can be saved.

Von Vorteil ist es ferner, wenn die Fahnenelemente Paare ausbilden, die aus zwei sich versetzt gegenüberliegenden Fahnenelementen bestehen. Durch diese Massnahme kann eine vorteilhafte Mischgeometrie bereitgestellt werden, bei der die Strömungsrichtung an dem einem Paar von Fahnenelementen verändert wird. Vorteilhaft sind die Fahnenelemente eines derartigen Paares dabei in einem Winkel, z. B. im Bereich von 20° bis 80°, zur Längsrichtung des Statikmischelementes schräg gestellt, wodurch die Mischeffizienz weiter erhöht wird.It is also advantageous if the flag elements form pairs that consist of two offset flag elements opposite each other. This measure can be a advantageous mixing geometry are provided, wherein the flow direction is changed at the one pair of flag elements. Advantageously, the flag elements of such a pair are at an angle, z. B. in the range of 20 ° to 80 °, inclined to the longitudinal direction of the static mixing element, whereby the mixing efficiency is further increased.

Vorteilhaft ist es ferner, wenn der Durchflussraum zwischen den sich versetzt gegenüberliegenden Fahnenelementen eines Paares verengt ist. Durch diese Massnahme wird die Strömungsgeschwindigkeit der zu mischenden Masse im Bereich der Paare erhöht, wodurch die Mischeffizienz weiter verbessert wird.It is also advantageous if the flow space between the offset opposing flag elements of a pair is narrowed. By this measure, the flow rate of the mass to be mixed in the region of the pairs is increased, whereby the mixing efficiency is further improved.

Günstig ist es ferner säulenartige Körper an wenigstens einem der Schalenteile vorzusehen, die in den Durchflussraum hineinragen und zu einer weiteren Verwirbelung der zu mischenden Masse beitragen.It is also favorable column-like body to provide at least one of the shell parts, which protrude into the flow space and contribute to a further turbulence of the mass to be mixed.

Die materialsparende Herstellung des Statikmischelementes kann dadurch weiter verbessert werden, dass die säulenartigen Körper wenigstens bereichsweise hohl ausgebildet sind und der Hohlraum zur Aussenfläche des Schalenteils hin offen ist. Dazu können am Formwerkzeug einer Spritzgussmaschine entsprechende Stifte oder Dorne vorgesehen sein. Die Basis der säulenförmigen Körper kann dabei konisch bis wulstartig verbreitert sein, wodurch weitere gunstige Fliessübergänge und gleichmässige Wandstärken erreicht werden.The material-saving production of the static mixing element can be further improved in that the columnar body are at least partially hollow and the cavity is open to the outer surface of the shell part. For this purpose, corresponding pins or mandrels can be provided on the mold of an injection molding machine. The base of the columnar body can be widened conically to bead-like, whereby more favorable flow transitions and uniform wall thicknesses can be achieved.

In den Figuren ist beispielhaft eine Ausführungsform eines erfindungsgemässen Statikmischelementes 10 dargestellt, welches mittels eines an diesem angeordneten Anschlussteils 25 z. B. an einer Ausgabevorrichtung für Mehrkomponenten-Massen, wie z. B. einem Auspressgerät für Zweikomponenten-Kartuschen, anbringbar ist.In the figures, an embodiment of an inventive static mixing element 10 is shown by way of example, which by means of a arranged on this connection part 25 z. B. on an output device for multi-component masses such. B. a dispenser for two-component cartridges, can be attached.

Das Statikmischelement 10 weist ein erstes Schalenteil 11 und ein zweites Schalenteil 12 auf, die über ein als Filmscharnier 33 ausgebildetes Verbindungsmittel miteinander klappbeweglich verbunden sind. Beide Schalenteile 11, 12 sind länglich ausgebildet und erstrecken sich entlang einer Längsrichtung 13 von einer Einlassöffnung 17 zu einer Auslassöffnung 18 des Statikmischelementes 10. Durch Zusammenklappen entlang des Filmscharniers 33 können beide Schalenteile 11, 12 zu einem röhrenförmigen Körper zusammengefügt werden. Dieses geschieht in der Regel bereits während des Herstellprozesses des Statikmischelementes 10. Die Schalenteile 11, 12 weisen jeweils zwei Dichtkanten 14, 15 auf an denen beide Schalenteile 11, 12 im zusammengeklappten Zustand aneinander liegen. Beide Schalenteile 11, 12 umfangen einen Durchflussraum 16 für die zu mischende Masse.The static mixing element 10 has a first shell part 11 and a second shell part 12, which are hingedly connected to each other via a connecting means formed as a film hinge 33. Both shell parts 11, 12 are elongated and extend along a longitudinal direction 13 from an inlet opening 17 to an outlet opening 18 of the static mixing element 10. By folding along the film hinge 33, both shell parts 11, 12 can be joined together to form a tubular body. This is usually done during the manufacturing process of the static mixing element 10. The shell parts 11, 12 each have two sealing edges 14, 15 on which both shell parts 11, 12 lie in the folded state together. Both shell parts 11, 12 embrace a flow space 16 for the mass to be mixed.

Im Bereich der Einlassöffnung 17 ist das Anschlussteil 25 angeordnet, welches hier an einem der Schalenteile 12 angeformt ist. Ein Kanal 26 im Anschlussteil 25 geht direkt über in den Durchflussraum 16. Das Anschlussteil 25 kann mit einer Festlegeeinrichtung, wie z. B. einem Innengewinde, zur Festlegung an einem Anschlussstück eines Auspressgerätes versehen sein.In the region of the inlet opening 17, the connection part 25 is arranged, which is formed here on one of the shell parts 12. A channel 26 in the connection part 25 goes directly into the flow space 16. The connection part 25 may be connected to a fixing device, such as. As an internal thread to be provided for fixing to a fitting of a Auspressgerätes.

An dem ersten Schalenteil 11 sind Fahnenelemente 21, 22 als Strömungsleitelemente 20 angeordnet. Diese Fahnenelemente 21, 22 weisen einen planaren Habitus auf, wobei sie eine Basis 29 aufweisen, die zum Schalenteil 11 hin konisch erweitert ist. Hierdurch wird ein weicher Übergang zur Innenfläche des Schalenteils 11 geschaffen. Die Fahnenelemente 21, 22 ragen über die Dichtkanten 14 des ersten Schalenteils hinaus und weisen eine Höhe auf die so ausgelegt ist, dass ihre Stirnflächen 23 im zusammengeklappten Zustand bis an die Innenfläche des zweiten Schalenteils 12 heranreicht. Die Kontur bzw. Form der Stirnflächen 23 ist dabei an die Innenkontur des zweiten Schalenteils 12 angepasst. Die Fahnenelemente 21, 22 sind teilweise hohl ausgebildet, wobei die Hohlräume 37, 38 zur Aussenfläche 27 des ersten Schalenteils 11 hin offen ausgebildet sind. Die Fahnenelemente 21, 22 verschliessen jeweils nicht den gesamten Durchflussraum 16, sondern lassen jeweils einen Abschnitt 35 frei. Dieser Abschnitt kann für verschiedene Fahnenelemente 21, 22 unterschiedlich gross ausgebildet sind.On the first shell part 11 flag elements 21, 22 are arranged as flow guide 20. These flag elements 21, 22 have a planar habit, wherein they have a base 29 which is flared towards the shell part 11. As a result, a soft transition to the inner surface of the shell part 11 is created. The flag elements 21, 22 protrude beyond the sealing edges 14 of the first shell part and have a height which is designed so that their end faces 23 in the folded state reaches as far as the inner surface of the second shell part 12. The contour or shape of the end faces 23 is adapted to the inner contour of the second shell part 12. The flag elements 21, 22 are partially hollow, wherein the cavities 37, 38 are formed open to the outer surface 27 of the first shell part 11. The flag elements 21, 22 in each case do not close off the entire flow space 16, but each leave a section 35 free. This section can be designed differently for different flag elements 21, 22.

Die Fahnenelemente 21, 22 sind in Paaren 24 gruppiert, wobei die Fahnenelemente 21, 22 eines Paares sich versetzt gegenüberliegend angeordnet sind. Die Fahnenelemente 21, 22 liegen dabei in einem Winkel α/ -α von ca. 70° zur Längsrichtung 13.The flag elements 21, 22 are grouped in pairs 24, with the flag elements 21, 22 of a pair being offset from each other. The flag elements 21, 22 lie at an angle α / α of about 70 ° to the longitudinal direction 13.

An den Stirnflächen 23 der Fahnenelemente 21, 22 sind als Rastelemente 31 ausgebildete Verbindungsmittel 30 angeordnet, die im zusammengeklappten Zustand der Schalenteile 11, 12 in als Gegenrastmittel 32 ausgebildete Verbindungsmittel 30 eingreifen und dort einrasten.At the end faces 23 of the flag elements 21, 22 are formed as locking elements 31 connecting means 30 which engage in the folded state of the shell parts 11, 12 designed as a counter-locking means 32 connecting means 30 and engage there.

In dem Statikmischelement 10 sind ferner noch säulenartige Körper 19 angeordnet, die der Turbulenzerhöhung einer durch das Statikmischelement 10 fliessenden Masse dienen. Diese Körper 19 weisen ebenfalls jeweils eine konisch bzw. wulstartig erweiterte Basis 36 auf und sind zumindest teilweise hohl ausgebildet. Die Hohlräume 39 sind dabei zu den Aussenflächen 27, 28 der Schalenteile 11, 12 hin offen ausgebildet.Column-like bodies 19, which serve to increase the turbulence of a mass flowing through the static mixing element 10, are also arranged in the static mixing element 10. These bodies 19 also each have a conically or bead-like extended base 36 and are at least partially hollow. The cavities 39 are open to the outer surfaces 27, 28 of the shell parts 11, 12 out.
