Abstract

A device for mixing a fluid, for example, carbon dioxide, with a liquid, for example an aqueous beverage solution has a combining part in which one or more infusion chambers are formed within a cylinder by chamber closing plates carried on a common axially shiftable stem. The mixture is passed from chamber to chamber through diaphragm orifices in these plates and the liquid is injected through radial bores in the cylinder wall which can be controlled by collars formed on the edges of the plates. The gas is introduced into the upstream chamber through another radial port. Downstream of the combining part, the mixture flows through an in-line mixer having walls provided with turbulence inducing formations and one of which is movable with the stem.

Description

Die Erfindung betrifft eine Vorrichtung zum Mischen eines Fluids und einer Flüssigkeit, insbesondere zum Eintragen von Kohlendioxid in ein wasserhaltiges Getränk, bestehend aus einem Vereinigungsteil und aus einem nachfolgenden Inline-Mischungsteil mit Turbulenzerzeugerausbildungen.The invention relates to a device for mixing a fluid and a liquid, in particular for introducing carbon dioxide into a water-containing beverage, consisting of a combination part and a subsequent inline mixing part with turbulence generator designs.

Unter einem Fluid wird im Rahmen der Erfindung ein Gas, eine Flüssigkeit, eine Gasmischung, eine Flüssigkeitsmischung und/oder eine Gas/Flüssigkeitsmischung verstanden. Entsprechend meint Flüssigkeit auch Flüssigkeitsmischungen. Vorrichtungen der in Rede stehenden Art in der Ausführungsform zum Eintragen von Kohlendioxid in ein wasserhaltiges Getränk bezeichnet man als Carbonisiersysteme.In the context of the invention, a fluid is understood to mean a gas, a liquid, a gas mixture, a liquid mixture and / or a gas / liquid mixture. Accordingly, liquid also means liquid mixtures. Devices of the type in question in the embodiment for introducing carbon dioxide into a water-containing beverage are referred to as carbonation systems.

Bei aus der Praxis bekannten Vorrichtungen der genannten Art wird das Fluid bzw. Kohlendioxid in die Flüssigkeit bzw. das Getränk eingedüst und hernach im nachfolgenden Inline-Mischungsteil bzw. -Mischer intensiv vermischt. Der Nachteil solcher Vorrichtungen ist darin zu sehen, daß der gewünschte Carbonisiereffekt nur für einen vorgegebenen Durchsatz gelingt. Bei anderen Durchsätzen wird keine zufriedenstellende Carbonisierung erreicht. Bei Einsatz vor einer Abfüllanlage, die in einem erheblichen Umfang mit unterschiedlichen Durchsätzen gefahren wird, kann im Rahmen der bekannten Maßnahmen nur mit unterschiedlich ausgelegten Vorrichtungen oder nachgeschalteten Puffersystemen gearbeitet werden, was extrem aufwendig ist. Hier will die Erfindung Abhilfe schaffen.In devices of the type mentioned which are known in practice, the fluid or carbon dioxide is injected into the liquid or the beverage and then intensively mixed in the subsequent inline mixing part or mixer. The disadvantage of such devices can be seen in the fact that the desired carbonization effect is only successful for a given throughput. Satisfactory carbonization is not achieved with other throughputs. When used in front of a bottling plant, which is operated to a considerable extent with different throughputs, only known devices or downstream buffer systems can be used within the scope of the known measures, which is extremely complex. The invention seeks to remedy this.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, daß bei in weiten Grenzen sich änderndem Durchsatz ein konstanter Eintragungseffekt erreicht wird.The invention has for its object to provide a device of the type mentioned in such a way that a constant entry effect is achieved with changing throughput within wide limits.

Hierzu lehrt die vorliegende Erfindung, daß das Vereinigungsteil aus einer zumindest eine Infusionskammer bildenden Zylinderwandung mit stromaufseitiger Fluidzufuhröffnung und mit zumindest einer stromabseitigen Radialbohrung zum Einspritzen der Flüssigkeit besteht, deren Querschnitt durch den Außenrand einer axial verstellbaren, mit Abfuhröffnungen versehenen Kammerabschlußplatte einstellbar ist.To this end, the present invention teaches that the union consists of a cylinder wall forming at least one infusion chamber with an upstream fluid supply opening and at least one downstream radial bore for injecting the liquid, the cross section of which can be adjusted through the outer edge of an axially adjustable chamber end plate provided with discharge openings.

Die Erfindung geht hierbei von der Erkenntnis aus, daß im Zuge eines Einspritzens der Flüssigkeit in das Fluid über Radialbohrungen mit einstellbarem Querschnitt ein konstanter Einmischungseffekt bei variierendem Durchsatz erreichbar ist. Die erfindungsgemäße Vorrichtung hat sich im Zuge einer praktischen Erprobung bestens bewährt und erlaubt auf wesentlich einfachere Art und Weise eine Einstellung bzw. Anpassung an variierende Durchsätze.The invention is based on the knowledge that in the course of injecting the liquid into the fluid via radial bores with an adjustable cross-section, a constant mixing effect with varying throughput can be achieved. The device according to the invention has proven itself in the course of practical testing and allows adjustment or adaptation to varying throughputs in a much simpler manner.

Für die weitere Ausgestaltung bestehen im Rahmen der Erfindung mehrere Möglichkeiten. So ist nach einer bevorzugten Ausführungsform vorgesehen, daß die Kammerabschlußplatte einen entgegen Strömungsrichtung spitz zulaufenden, kragenförmigen Außenrand aufweist. Der Mischungseffekt wird weiter gefördert, wenn die Abfuhröffnungen als Blendenbohrungen ausgeführt sind. Da nicht ausgeschlossen werden kann, daß sich Verunreinigungen zwischen Zylinderwandung und Außenrand festsetzen, ist nach einer bevorzugten Ausführungsform vorgesehen, daß die Zylinderwandung jeweils unterhalb der in einer Ebene liegenden Radialbohrungen mit einer umlaufenden Reinigungsnut versehen ist, deren Höhe größer ist als die des Außenrandes; durch entsprechende Absenkung der Kammerabschlußplatte in den Bereich der Reinigungsnut wird dann auch die Kammerabschlußplatte am Außenrand umströmt und gereinigt. Je nach Art der zu mischenden Fluid/Flüssigkeitskombination kann bereits eine Infusionskammer im Vereinigungsteil genügen. In anderen Fällen, wie z. B. beim Eintragen von Kohlendioxid in ein wasserhaltiges Getränk, empfiehlt es sich jedoch, mehrere, insbesondere vier axial hintereinander angeordnete Infusionskammern vorzusehen; in der ersten Kammer wird dann das Fluid oberhalb des Sättigungsgleichgewichtes eingegeben, so daß sich eine Zwei-Phasen-Mischung bildet, die auch der Geräuschminderung zugute kommt; in den weiteren Stufen erfolgt dann eine Rückverdünnung bis auf die gewünschte Fluidkonzentration. Die Kammerabschlußplatten sämtlicher Infusionskammern sind zweckmäßigerweise an einer gemeinsamen zentralen Stellstange befestigt, so daß zur Einstellung der Kammerabschlußplatten sämtlicher Infusionskammern nur eine einzige gemeinsame Betätigung erforderlich ist. Die Flüssigkeitszufuhr kann ohne weiteres und in besonders einfacher Weise über einen Ringraum erfolgen, der die Zylinderwandung im Bereich der Radialbohrung umgibt. Die in die erste Infusionskammer einmündende Fluidzufuhröffnung kann ebenfalls in der Zylinderwandung vorgesehen sein, so daß am stromaufseitigen Ende der Zylinderwandung ein Stellantrieb an der Stellstange befestigt werden kann. Die Stellstange kann dann entweder in Abhängigkeit von einem äußeren Signal (Druck, Durchfluß usw.) oder von einem inneren Systemdruck, z. B. über eine am stromaufseitigen Ende der Zylinderwandung befindliche Steuermembran, gesteuert werden.There are several possibilities for the further configuration within the scope of the invention. According to a preferred embodiment, it is provided that the chamber end plate has a collar-shaped outer edge that tapers towards the direction of flow. The mixing effect is further promoted if the discharge openings are designed as orifices. Since it cannot be ruled out that contamination fix between cylinder wall and outer edge, it is provided according to a preferred embodiment that the cylinder wall is provided below the radial bores lying in one plane with a circumferential cleaning groove, the height of which is greater than that of the outer edge; by correspondingly lowering the chamber end plate into the area of the cleaning groove, the chamber end plate is then also flowed around and cleaned at the outer edge. Depending on the type of fluid / liquid combination to be mixed, an infusion chamber in the union part may already be sufficient. In other cases, such as B. when entering carbon dioxide in a water-containing beverage, it is recommended to provide several, especially four axially arranged infusion chambers; The fluid above the saturation equilibrium is then introduced into the first chamber, so that a two-phase mixture is formed which also benefits from noise reduction; In the further stages, the mixture is then diluted back to the desired fluid concentration. The chamber end plates of all infusion chambers are expediently fastened to a common central actuating rod, so that only one single actuation is required to adjust the chamber end plates of all infusion chambers. The liquid can be supplied easily and in a particularly simple manner via an annular space which surrounds the cylinder wall in the region of the radial bore. The fluid supply opening opening into the first infusion chamber can also be provided in the cylinder wall, so that an actuator can be attached to the actuating rod at the upstream end of the cylinder wall. The actuating rod can then either depending on an external signal (pressure, flow, etc.) or an internal system pressure, for. B. can be controlled via a control membrane located at the upstream end of the cylinder wall.

Nach einer weiteren bevorzugten Ausführungsform, der im Rahmen der Erfindung auch selbständige erfinderische Bedeutung zukommt, besteht das Inline-Mischungsteil aus einer oder je nach Durchsatzleistung auch mehreren parallelen, axial durchströmten Ringkammern, die an ihren einander zugewandten Mantelflächen komplementäre Turbulenzerzeugerausbildungen aufweisen, durch axiale Relativverstellung der zugeordneten Mantelflächen ergeben sich dann änderbare Durchtrittsquerschnitte und Wirbelkammern. Die äußere Ringkammer des Inline-Mischungsteiles kann dabei bevorzugt von einer Verlängerung der Zylinderwandung und einem darin axial verstellbar angeordneten Zusatzzylinder gebildet sein. Vorteilhaft ist in diesem Zusammenhang auch eine Ausführungsform, bei der der Zusatzzylinder ebenfalls an der Stellstange befestigt ist, d. h. daß das Inline-Mischungsteil gemeinsam mit dem Vereinigungsteil einstellbar ist. Die Turbulenzerzeugerausbildungen können aus Radialflanschen bestehen, mit deren Hilfe das Inline-Mischungsteil bis in eine Schließstellung verstellbar ist. Besonders geeignet sind Turbulenzerzeugerausbildungen, die in Strömungsrichtung gesehen ein sägezahnförmiges Profil aufweisen.According to a further preferred embodiment, which also has independent inventive significance in the context of the invention, the inline mixing part consists of one or, depending on the throughput, also a plurality of parallel, axially flowed-through annular chambers which have complementary turbulence generator designs on their mutually facing lateral surfaces by means of axial relative adjustment of the assigned lateral surfaces then result in changeable passage cross sections and swirl chambers. The outer annular chamber of the inline mixing part can preferably be formed by an extension of the cylinder wall and an additional cylinder arranged axially adjustable therein. In this context, an embodiment is also advantageous in which the additional cylinder is also attached to the actuating rod, i. H. that the inline mixing part is adjustable together with the union part. The turbulence generator designs can consist of radial flanges, with the aid of which the inline mixing part can be adjusted into a closed position. Turbulence generator designs that have a sawtooth-shaped profile when viewed in the direction of flow are particularly suitable.

Die in den Figuren dargestellte Vorrichtung dient zum Mischen eines Fluids und einer Flüssigkeit, insbesondere zum Eintragen von Kohlendioxid in ein wasserhaltiges Getränk. In ihrem grundsätzlichen Aufbau besteht die Vorrichtung aus einem Vereinigungsteil 1 und aus einem nachfolgenden Inline-Mischungsteil 2, wobei letzteres aus zumindest einer im wesentlichen axial durchströmten, Turbulenzerzeugerausbildungen 3 aufweisenden Ringkammer 4 besteht.The device shown in the figures is used to mix a fluid and a liquid, in particular to introduce carbon dioxide into a water-containing beverage. In its basic structure, the device consists of a union part 1 and a subsequent inline mixing part 2, the latter consisting of at least one ring chamber 4 with an essentially axial flow and having turbulence generator designs 3.

Das Vereinigungsteil 1 besteht aus einer Zylinderwandung 5, die zunächst eine erste Infusionskammer 6 bildet. Stromaufseitig ist eine Fluidzufuhröffnung 7 vorgesehen, während darunter, d. h. stromabseitig in einer Ebene mehrere Radialbohrungen 8 zum Einspritzen der Flüssigkeit vorgesehen sind. Der Querschnitt dieser in einer Ebene vorgesehenen Radialbohrungen 8 ist durch den Außenrand 9 einer axial verstellbaren, mit Abfuhröffnungen 10 versehenen Kammerabschlußplatte 11 einstellbar.The union part 1 consists of a cylinder wall 5, which initially forms a first infusion chamber 6.

The cross section of these radial bores 8 provided in one plane is adjustable through the outer edge 9 of an axially adjustable chamber end plate 11 provided with discharge openings 10.

Wie man aus der Fig. 1 und dem vergrößerten Detail Z entnimmt, weist die Kammerabschlußplatte 11 einen kragenförmigen Außenrand 9 auf, der entgegen Strömungsrichtung spitz zuläuft. Die Abfuhröffnungen 10 sind als Blendenbohrungen ausgeführt. Unterhalb der in einer Ebene liegenden Radialbohrungen 8 ist die Zylinderwandung 5 noch mit einer umlaufenden Reinigungsnut 13 versehen, deren Höhe größer ist als die des Außenrandes 9.As can be seen from FIG. 1 and the enlarged detail Z, the chamber end plate 11 has a collar-shaped outer edge 9 which tapers towards the direction of flow. The discharge openings 10 are designed as aperture bores. Below the radial bores 8 lying in one plane, the cylinder wall 5 is also provided with a circumferential cleaning groove 13, the height of which is greater than that of the outer edge 9.

Hinter der beschriebenen ersten Infusionskammer 6 folgen drei weitere axial hintereinander angeordnete Infusionskammern 14-16, die identisch ausgebildet sind und über die Blendenbohrungen 10 der jeweils unmittelbar vorgeschalteten Infusionskammer 6 bzw. 14, 15 versorgt werden. Sämtliche Kammerabschlußplatten 11 der Infusionskammer 6, 14-16 sind an einer gemeinsamen zentralen Stellstange 17 befestigt.Behind the first infusion chamber 6 described there follow three further axially arranged infusion chambers 14-16, which are of identical design and are supplied via the aperture bores 10 of the immediately preceding infusion chamber 6 and 14, 15, respectively. All chamber end plates 11 of the infusion chamber 6, 14-16 are attached to a common central adjusting rod 17.

Im Bereich der Radialbohrungen 8 für die Zuführung der Flüssigkeit ist die Zylinderwandung 5 von einem die Flüssigkeit zuführenden Ringraum 18 umgeben.

Diese weitere Zylinderwandung 19 enthält auch die Zuführstutzen 27, 21 und 22 für das Fluid, die Flüssigkeit und die Abfuhr der Mischung. Entsprechend ist die Fluidzufuhröffnung 7 in der erstgenannten Zylinderwandung 5 vorgesehen, während das stromaufseitige Ende dieser Zylinderwandung durch eine Steuermembran oder einen Stellantrieb 23 verschlossen ist, an der die Stellstange 18 befestigt ist.In the area of the radial bores 8 for the supply of the liquid, the cylinder wall 5 is surrounded by an annular space 18 which supplies the liquid. This annular space 18 is formed by a further cylinder wall 19 and annular separating flanges 20. This further cylinder wall 19 also contains the supply ports 27, 21 and 22 for the fluid, the liquid and the discharge of the mixture. Accordingly, the fluid supply opening 7 is provided in the first-mentioned cylinder wall 5, while the upstream end of this cylinder wall is closed by a control membrane or an actuator 23 to which the actuating rod 18 is attached.

Die äußere Ringkammer 4 des Inline-Mischungsteils 2 ist von einer Verlängerung 24 der Zylinderwandung 5 und einem darin axial verstellbar angeordneten Zusatzzylinder 25 gebildet, wobei die Verlängerung 24 sowie der Zusatzzylinder 25 an ihren einander zugewandten Mantelflächen komplementäre Turbulenzerzeugerausbildungen 3 in Form von Radialflanschen 26 aufweisen. Der Zusatzzylinder 25 ist ebenfalls an der Stellstange 17 befestigt. Mit Hilfe der genannten Radialflansche 26 kann das Inline-Mischungsteil 2 bis in eine Schließstellung verstellbar sein. Das verdeutlichen die Figuren 2 bis 5. Bei der Ausführungsform nach Fig. 2 sind die Turbulenzerzeugerausbildungen 3 aus rechteckigen Flanschen gebildet. Bei der Ausführungsform nach Fig. 3 weisen die Turbulenzerzeugerausbildungen 3 einen dreieckigen Querschnitt auf. Bei der Ausführungsform nach Fig. 4 sind die Radialflansche 26 durch zwischenliegende halbkreisförmige Ausnehmungen gebildet. Bei der Ausführungsform nach Fig. 5 schließlich ist eine sägezahnförmige Gestaltung gewählt.The outer annular chamber 4 of the inline mixing part 2 is formed by an extension 24 of the cylinder wall 5 and an additional cylinder 25 arranged axially adjustable therein, the extension 24 and the additional cylinder 25 having complementary turbulence generator designs 3 in the form of radial flanges 26 on their mutually facing lateral surfaces.
