StatikmischerStatic mixer

Die Erfindung betrifft einen Statikmischer zur Anbringung am Austrittsende einer Verdrängungskolben für mehrere Komponenten aufweisende Kartusche, mit in einer Tülle zwischen deren Eintrittsöffnung und deren Austrittsöffnung angeordneten Wendelungen. The invention relates to a static mixer for attachment to the outlet end of a cartridge containing a displacement piston for several components, with spirals arranged in a nozzle between its inlet opening and its outlet opening.

Derartige Kartuschen dienen zum Verteilen eines beispielsweise zwei Komponenten aufweisenden Gemisches. Bei den zu verteilenden Komponenten kann es sich beispielsweise um Harz, Beschleuniger, Härter, Zement, Bindemittel od. dgl. handeln. Die Kartuschen werden eingesetzt, um beispielsweise aushärtende Kleber oder Mörtel in Bohrungen zu verteilen, in welche ein Anker mittels eines Klebers oder Mörtels einsetzbar und damit befestigbar ist. Die Kartuschen weisen beispielsweise eine zur Aufnahme einer Komponente vorgesehene Innenkammer und eine zur Aufnahme einer weiteren Komponente vorgesehene Ringkammer auf, die in einer gemeinsamen Spritzöffnung münden. Jede Komponente wird mit einem ihr zugeordneten Verdrängungskolben aus der Kammer herausgedrückt. Die Komponenten kommen im Bereich des Austrittsendes der Kartusche zusammen.Such cartridges are used to distribute a mixture, for example, with two components. The components to be distributed can be, for example, resin, accelerator, hardener, cement, binding agent or the like. The cartridges are used, for example, to distribute hardening adhesives or mortars into holes into which an anchor can be inserted and secured using an adhesive or mortar. The cartridges have, for example, an inner chamber intended to accommodate one component and an annular chamber intended to accommodate another component, which open into a common spray opening. Each component is pressed out of the chamber with an assigned displacement piston. The components come together in the area of the outlet end of the cartridge.

Um die aus den beiden Zylindern austretenden Komponenten zu mischen ist es bekannt, im Bereich des Austrittsendes der Kartouche einen Statikmischer anzuordnen, beispielsweise auf-In order to mix the components emerging from the two cylinders, it is known to arrange a static mixer in the area of the exit end of the cartridge, for example on

zuschrauben. Der Statikmischer ist in Form einer Tülle ausgebildet und weist zwischen deren Eintrittsöffnung und deren Austrittsöffnung Wendelungen auf. Die mittels der Verdrängungskolben gemeinsam aus den Zylindern herausgedrückten Kolben werden durch Wirkung der Wendelungen in der Tülle vermischt und treten gemeinsam aus der Austrittsöffnung der Tülle aus.screw it shut. The static mixer is designed in the form of a nozzle and has spirals between its inlet and outlet openings. The pistons, which are pressed out of the cylinders together by the displacement pistons, are mixed by the effect of the spirals in the nozzle and exit together from the outlet opening of the nozzle.

Die durch die Wendelungen auftretende Mischwirkung ist umso größer, je größer die Anzahl der Wendelungen und die Länge der Tülle ist. Dementsprechend erfordert eine gute Mischwirkung eine relativ große Baulänge des Statikmischers. Die Erzielung einer guten Mischwirkung ist insbesondere dann erforderlich, wenn das Verhältnis der zu mischenden Komponenten extrem unterschiedlich ist, wenn also beispielsweise eine Komponente 97 % und die andere Komponente 3 % beträgt. Es hat sich gezeigt, daß bei derartigen Verhältnissen mit herkömmlichen Statikmischern keine ausreichende Mischwirkung erzielt werden kann.The mixing effect caused by the spirals is greater the greater the number of spirals and the length of the nozzle. Accordingly, a good mixing effect requires a relatively large length of the static mixer. Achieving a good mixing effect is particularly necessary when the ratio of the components to be mixed is extremely different, for example when one component is 97% and the other component is 3%. It has been shown that in such conditions, a sufficient mixing effect cannot be achieved with conventional static mixers.

Der Erfindung liegt die Aufgabe zugrunde, herkömmliche Statikmischer der eingangs genannten Art in möglichst einfacher Weise so umzugestalten bzw. verbessern, daß auch derartige "extreme" Mischungsverhältnisse mit guter Mischwirkung bearbeitet werden können.The invention is based on the task of redesigning or improving conventional static mixers of the type mentioned at the beginning in the simplest possible way so that even such "extreme" mixing ratios can be processed with a good mixing effect.

Zur Lösung dieser Aufgabe schlägt die Erfindung vor, daß im Eingangsbereich der Tülle ein quer zur Längsrichtung der Tülle angeordneter Aufprallkörper für die zugeführten Komponenten vorgesehen ist, und über den Umfang des Aufprallkörpers verteilt mehrere Ausnehmungen vorgesehen sind, welche Durchgangsöffnungen zwischen dem Aufprallkörper und der Innenwand der Tülle freigeben.To solve this problem, the invention proposes that an impact body arranged transversely to the longitudinal direction of the spout is provided in the inlet area of the spout for the supplied components, and that several recesses are provided distributed over the circumference of the impact body, which open up through openings between the impact body and the inner wall of the spout.

Hiermit wird erreicht, daß die beiden aus den Zylindern in der Kartusche austretenden Komponenten durch Wirkung des Aufprallkörpers umgelenkt und dann jeweils gemeinsam durch dieThis ensures that the two components emerging from the cylinders in the cartridge are deflected by the impact body and then passed together through the

Durchgangsöffnungen hindurchgepreßt werden. Dadurch wird eine Aufteilung der gemeinsam herangeführten Komponenten in eine Vielzahl von Teilströmen erreicht, die jeweils bereits aus den gemeinsamen Komponenten bestehen. Auf diese Weise erfolgt eine Vorvermischung der Komponenten, bevor dann die Teilströme - in Strömungsrichtung gesehen hinter dem Aufprallkörper - gemeinsam dem die Wendelungen aufweisenden Bereich der Tülle zugeführt werden. Infolge dieser Vorvermischung kann die Länge der nachgeschalteten Wendelungen bei gleichem Mischeffekt kürzer als bei Statikmischern nach dem Stande der Technik gestaltet werden. Dementsprechend kann auch die ganze Statikmischanordnung kürzer gestaltet werden. Dies hat weiterhin den günstigen Effekt, daß die für den Mischvorgang erforderliche Preßkraft geringer als bei Statikmischern nach dem Stande der Technik ist.through openings. This results in the components being fed together being divided into a number of partial flows, each of which already consists of the same components. In this way, the components are pre-mixed before the partial flows - behind the impact body as seen in the direction of flow - are then fed together to the area of the nozzle that has the spirals. As a result of this pre-mixing, the length of the downstream spirals can be made shorter than with state-of-the-art static mixers, while maintaining the same mixing effect. Accordingly, the entire static mixing arrangement can also be made shorter. This also has the beneficial effect that the pressing force required for the mixing process is lower than with state-of-the-art static mixers.

Vorzugsweise kann vorgesehen sein, daß der Aufprallkörper als Prallplatte mit über den Umfang verteilt angeordneten Stegen ausgebildet ist, zwischen denen die die Durchgangsöffnungen bildenden Ausnehmungen vorhanden sind. In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, daß die Stege über wenigstens eine Ebene der Prallplatte in Längsrichtung der Tülle vorstehend ausgebildet sind. Auf diese Weise kann erreicht werden, daß die Prallplatte in den Statikmischer eingesetzt und mittels der Stege gehalten wird.Preferably, the impact body can be designed as an impact plate with webs distributed around the circumference, between which the recesses forming the through-openings are present. In a further embodiment of the invention, the webs can be designed to protrude over at least one plane of the impact plate in the longitudinal direction of the nozzle. In this way, the impact plate can be inserted into the static mixer and held in place by means of the webs.

Ein weiterer Vorteil der Erfindung besteht darin, daß Statikmischer herkömmlicher Bauart, die bei einem größenordnungsmäßig gleichen Verhältnis zu mischender Komponenten praktikable Mischungsergebnisse erzielen, die aber für "extreme" Mischungsverhältnisse ungeeignet sind, durch einfaches Einsetzen des Aufprallkörpers so umgerüstet werden können, daß auch extreme Mischungsverhältnisse verarbeitet werden können.A further advantage of the invention is that static mixers of conventional design, which achieve practical mixing results with a ratio of the same order of magnitude to the components to be mixed, but which are unsuitable for "extreme" mixing ratios, can be converted by simply inserting the impact body so that even extreme mixing ratios can be processed.

Nachfolgend wird anhand der beigefügten Zeichnung ein Ausführungsbeispiel der Erfindung näher erläutert. Es zeigen:An embodiment of the invention is explained in more detail below with reference to the accompanying drawing. They show:

Fig. 1 einen schematischen Längsschnitt durch eine Kartusche mit aufgeschraubtem Statikmischer;Fig. 1 is a schematic longitudinal section through a cartridge with a screwed-on static mixer;

Fig. 2 eine Schnittdarstellung längs der Linie II-II in vergrößertem Maßstab.Fig. 2 is a sectional view along the line II-II on an enlarged scale.

Auf eine insgesamt mit 1 bezeichnete Kartusche ist ein insgesamt mit 2 bezeichneter Statikmischer aufgeschraubt. Die Kartusche 1 weist ein zylindrisches Gehäuse 3 auf, in dessen Innerem ein Innenrohr 4 angeordnet ist. Der zwischen dem Gehäuse 3 und dem Außenumfang des Innenrohrs befindliche Ringraum 5 dient zur Aufnahme einer zu verteilenden Komponente A, und der Innenraum 6 des Innenrohres 4 zur Aufnahme einer weiteren zur verteilenden Komponente B. Diese Komponenten können mittels gemeinsam in Pfeilrichtung C beweglicher Verdrängungskolben 7 und 8 entsprechend der zeichnerischen Darstellung nach rechts aus der Kartusche 1 herausgedrückt werden.A static mixer, designated as 2, is screwed onto a cartridge, designated as 1. The cartridge 1 has a cylindrical housing 3, inside which an inner tube 4 is arranged. The annular space 5 located between the housing 3 and the outer circumference of the inner tube serves to accommodate a component A to be distributed, and the interior 6 of the inner tube 4 serves to accommodate another component B to be distributed. These components can be pressed out of the cartridge 1 to the right by means of displacement pistons 7 and 8 that can move together in the direction of arrow C, as shown in the drawing.

Der Statikmischer 2 ist mittels eines Innengewindes 9 auf ein Außengewinde 10 eines Abschlußteils 11 der Kartusche aufgeschraubt. Der Statikmischer 2 ist in Form einer Tülle 12 ausgebildet. Die Tülle 12 ist außen mit Versteifungskörpern 13 versehen und weist in ihrem Inneren Wendelungen 14 auf, durch deren Wirkung die aus den Zylindern 5 und 6 herangeführten Komponenten vermischt werden. Die vermischten Komponenten treten dann durch die Austrittsöffnung 15 des Statikmischers aus.The static mixer 2 is screwed onto an external thread 10 of a closure part 11 of the cartridge by means of an internal thread 9. The static mixer 2 is designed in the form of a nozzle 12. The nozzle 12 is provided with stiffening bodies 13 on the outside and has spirals 14 on the inside, the effect of which mixes the components supplied from the cylinders 5 and 6. The mixed components then exit through the outlet opening 15 of the static mixer.

Im Eingangsbereich 16 des Statikmischers ist ein insgesamt mit 17 bezeichneter Aufprallkörper vorgesehen. Der Aufprallkörper 17 weist eine Prallplatte 18 auf, welche quer zur Längsrichtung der Tülle 12 verlaufend angeordnet ist. Die Prallplatte 18 ist bei dem dargestellten Ausführungsbeispiel von insgesamt acht Stegen 19 umgeben, welche sich über die der Kartusche zugewandte Ebene der Prallplatte 18 in Längsrichtung der Tülle erstrecken, wie aus Fig. 1 ersichtlich. Der Außendurchmesser des Prallkörpers mit den Stegen ent-In the inlet area 16 of the static mixer, an impact body, designated as a whole by 17, is provided. The impact body 17 has an impact plate 18, which is arranged transversely to the longitudinal direction of the nozzle 12. In the embodiment shown, the impact plate 18 is surrounded by a total of eight webs 19, which extend over the plane of the impact plate 18 facing the cartridge in the longitudinal direction of the nozzle, as can be seen from Fig. 1. The outer diameter of the impact body with the webs corresponds to

- ^abdem Innendurchmesser des Bereiches 20 der Tülle, während der Durchmesser der Prallplatte geringer ist, so daß zwischen der Prallplatte 18 und der Innenwandung der Tülle ein Ringspalt gebildet wird, der durch die Stege 19 in bei dem dargestellten Ausführungsbeispiel insgesamt acht Einzelöffnungen unterteilt ist. Der Aufprallkörper 17 ist somit ein "sternchenförmig" ausgebildetes Teil, welches in den Eingangsbereich des Statikmischers eingesetzt ist.- ^ab the inner diameter of the area 20 of the nozzle, while the diameter of the impact plate is smaller, so that between the impact plate 18 and the inner wall of the nozzle an annular gap is formed, which is divided by the webs 19 into a total of eight individual openings in the embodiment shown. The impact body 17 is thus a "star-shaped" part which is inserted into the inlet area of the static mixer.

Durch Wirkung des Aufprallkörpers 17 wird eine Vorvermischung der aus der Kartusche austretenden Komponenten erreicht, und zwar werden die Komponenten durch Wirkung des Aufprallkörpers zunächst quer zu ihrer Strömungsrichtung umgelenkt und dann in insgesamt acht Teilströme aufgeteilt, welche durch die Öffnungen 21 hindurchtreten, wobei alle acht Teilströme 21 bereits Anteile beider Komponenten aufweisen. Diese Teilströme werden dann durch die Wendelungen geleitet und treten in vermischtem Zustand an der Austrittsöffnung 15 aus.The effect of the impact body 17 results in a pre-mixing of the components emerging from the cartridge, and the components are initially deflected transversely to their flow direction by the effect of the impact body and then divided into a total of eight partial flows which pass through the openings 21, whereby all eight partial flows 21 already contain portions of both components. These partial flows are then guided through the coils and emerge in a mixed state at the outlet opening 15.

Durch die vor den Wendelungen auftretende Vorvermischung der Komponenten wird eine verbesserte Mischwirkung erzielt.The pre-mixing of the components before the spirals achieves an improved mixing effect.
