Abstract

A description is given of an installation (10) for the precise metering and homogeneous mixing of two liquid mixing components which are each stored in a container (12, 14). Each container (12, 14) is assigned a pump (16, 18) in order to dispense a defined quantity of the mixing component. The installation (10) has two supply lines (20, 24), which have their first ends (22, 26) connected to the two pumps (16, 18) and have their second ends (28, 30), which are remote from the first, opening out into a mixing antechamber (32) of a mixer (34). The pumps (16, 18) ensure a constant volume flow of the two mixing components over a wide viscosity and pressure range of the mixing components and, as they enter into the mixing antechamber (32) of the mixer (34), the mixing components have the same supply pressures, disadvantageous pulsating volume flows of the mixing components thus being prevented by the homogeneity of the mixture of the two mixing components.

Description

Dosier- und Mischanlage für flüssige Zweikomponentensvsteme Dosing and mixing system for liquid two-component systems
Die Erfindung betrifft eine Anlage zum Dosieren und Mischen von zwei flüssigen Mischkomponenten, die jeweils in einem Behälter gelagert sind, wobei jedem Behälter zur Ausgabe einer definierten Menge der Mischkomponente eine Pumpe zugeordnet ist, und zum Mischen der beiden definierten Mengen der Mischkomponenten ein Mischer vorgesehen ist.The invention relates to a system for metering and mixing of two liquid mixing components, each stored in a container, each container for dispensing a defined amount of the mixing component is associated with a pump, and for mixing the two defined amounts of the mixing components, a mixer is provided ,
Beim Dosieren und Mischen von flüssigen Mischkomponenten unterschiedlicher Viskosität sind bislang pulsierende Volumenströme oftmals nicht zu vermeiden. Das gilt insbesondere dann, wenn das Viskositätsverhältnis der beiden Mischkomponenten groß ist und beispielsweise 100:1 beträgt. Entsprechend problematisch ist es, wenn die Quantität der höherviskosen Mischkomponente im Vergleich zur Quantität der niedrigviskosen Mischkomponente groß ist.When dosing and mixing liquid mixing components of different viscosity pulsating flow rates are often unavoidable. This is especially true when the viscosity ratio of the two mixing components is large and, for example, 100: 1. It is correspondingly problematical if the quantity of the higher-viscosity mixed component is large in comparison to the quantity of the low-viscosity mixed component.
Der Erfindung liegt die Aufgabe zugrunde, eine Anlage der eingangs genannten Art zu schaffen, die eine optimale Dosierung und Mischung von flüssigenMischkomponenten ermöglicht, deren Dosierverhältnis zwischen 1 :1 bis 100:1 und deren Viskositätsverhältnis zwischen 1 :1 und 100:1 betragen kann.The invention has for its object to provide a system of the type mentioned above, which allows optimum metering and mixing of liquid mixing components whose dosing ratio between 1: 1 to 100: 1 and whose viscosity ratio between 1: 1 and 100: 1 can be.
Diese Aufgabe wird bei einer Anlage der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass zwei Zuführleitungen vorgesehen sind, die mit ihren ersten Enden an die beiden Pumpen angeschlossen sind und die mit ihren davon entfernten zweiten Enden in eine Mischvorkammer des Mischers einmünden, wobei die beiden Pumpen über einen großen Viskositäts- und Druckbereich der beiden flüssigen Mischkomponenten einen konstanten Volumenstrom der Mischkomponenten sicherstellen und die Mischkomponenten beim Eintritt in die Mischvorkammer die gleichen Eingangsdrücke besitzen.This object is achieved in a system of the type mentioned in the present invention, that two supply lines are provided, which are connected with their first ends to the two pumps and open with their remote second ends in a Mischvorkammer the mixer, wherein the two pumps ensure a constant volume flow of the mixing components over a large viscosity and pressure range of the two liquid mixing components and the mixing components have the same inlet pressures when entering the Mischvorkammer.
Durch die erfindungsgemäße Ausbildung der Anlage werden pulsierende Volumenströme der beiden Mischkomponenten auch dann zuverlässig verhindert, wenn das Dosierverhältnis der Komponenten und deren Viskositätsverhältnis von 1 verschieden bzw. sehr groß sind. Mit der erfindungsgemäßen Anlage ist es also möglich, zwei flüssige Mischkomponenten nicht nur exakt zu dosieren, sondern auch eine homogene Mischung der beiden Mischkomponenten nicht nur dann zu erzielen, wenn ihr Dosierverhältnis und ihr Viskositätsverhältnis größenordnungsmäßig bei 1 liegt, sondern wenn das Dosierverhältnis im Bereich zwischen 1 :1 bis 100:1 und ihr Viskositätsverhältnis im Bereich zwischen 1 :1 und 100:1 beträgt.The inventive design of the system pulsating flow rates of the two mixing components are reliably prevented even if the metering ratio of the components and their viscosity ratio of 1 are different or very big. With the system according to the invention, it is thus possible not only to accurately meter two liquid mixing components, but also to achieve a homogeneous mixture of the two mixing components not only if their metering ratio and their viscosity ratio is 1, but if the metering ratio in the range between 1: 1 to 100: 1 and their viscosity ratio is in the range between 1: 1 and 100: 1.
Bei der erfindungsgemäßen Anlage können die gleichen Eingangsdrücke der flüssigen Mischkomponenten beim Eintritt in die Mischvorkammer durch Dimensionierung der beiden Zuführleitungen erreicht werden. Das gilt insbesondere für erfindungsgemäße Anlagen, mit welchen stets gleiche Mischkomponenten, d.h. Mischkomponenten gleicher Viskosität und gleichen Dosierverhältnisses, verarbeitet werden.In the system according to the invention, the same inlet pressures of the liquid mixing components can be achieved when entering the Mischvorkammer by dimensioning the two supply lines. This applies in particular to systems according to the invention, with which always identical mixing components, i. Mixing components of the same viscosity and the same metering ratio, are processed.
Desgleichen ist es möglich, dass die gleichen Eingangsdrücke derLikewise it is possible that the same input pressures of the
Mischkomponenten beim Eintritt in die Mischvorkammer durch in den Zuführleitungen vorgesehene Drosseleinrichtungen eingestellt werden.Mixing components are set when entering the Mischvorkammer by provided in the supply lines throttling devices.
Bei der erfindungsgemäßen Anlage ist der Mischer vorzugsweise von einem statischen Mischer gebildet.In the system according to the invention, the mixer is preferably formed by a static mixer.
Um eine unerwünschte Rückströmung teilvermischter Mischkomponenten aus der Mischvorkammer in die Zuführleitungen zu verhindern, kann es zweckmäßig sein, wenn die beiden Zuführleitungen eine Absperrvorrichtung aufweisen.In order to prevent undesired backflow of partially mixed components from the Mischvorkammer in the supply lines, it may be expedient if the two supply lines have a shut-off.
Um eine Überdosierung einer der beiden Mischkomponenten beim Start der erfindungsgemäßen Anlage zu verhindern, werden die Anfahrcharakteristiken der beiden Pumpen aufeinander abgestimmt.In order to prevent overdosing of one of the two mixing components when starting the system according to the invention, the starting characteristics of the two pumps are matched to one another.
In der Mischvorkammer ist zweckmäßigerweise ein Dispenser vorgesehen. Dieser Dispenser kann von wenigstens einem Lochblech, einem Sieb, einem Gitternetz o. dgl. gebildet sein. Die erfindungsgemäße Anlage ist zur Verarbeitung vergleichsweise großer Quantitäten von zwei flüssigen Mischkomponenten geeignet, wobei eine exakte Dosierung und eine homogene Mischung der beiden Mischkomponenten gewährleistbar ist. Derartige Zweikomponenten-Mischsysteme erfordern ein konstantes Verhältnis der beiden Mischkomponenten mit geringen Toleranzen der dosierten Mengen, wobei auch bei großem Viskositätsverhältnis und großem Dosierverhältnis der Mischkomponenten eine homogene Mischung der Komponenten verwirklicht wird.In the Mischvorkammer expediently a dispenser is provided. This dispenser can be formed by at least one perforated plate, a sieve, a grid or the like. The plant according to the invention is suitable for processing comparatively large quantities of two liquid mixing components, wherein an exact metering and a homogeneous mixture of the two mixing components can be ensured. Such two-component mixing systems require a constant ratio of the two mixing components with low tolerances of the metered amounts, wherein a homogeneous mixture of the components is realized even with a high viscosity ratio and high metering ratio of the mixing components.
Weitere Einzelheiten, Merkmale und Vorteile ergeben sich aus der nachfolgenden Beschreibung eines in der Zeichnung schematisch verdeutlichten Ausführungsbeispieles der erfindungsgemäßen Anlage.Further details, features and advantages will become apparent from the following description of a schematically illustrated in the drawing embodiment of the system according to the invention.
Es zeigen:Show it:
Figur 1 eine schematische Darstellung der Anlage, und Figur 2 eine vergrößerte Darstellung des Details Il in Figur 1.Figure 1 is a schematic representation of the system, and Figure 2 is an enlarged view of the detail Il in Figure 1.
Figur 1 zeigt in einer schematischen Darstellung eine Ausbildung der Anlage 10 zum exakten Dosieren und homogenen Mischen von zwei flüssigen Mischkomponenten, die jeweils in einem Behälter 12, 14 gelagert sind. Jedem der beiden Behälter 12, 14 ist eine Pumpe 16, 18 zugeordnet, die zur Ausgabe einer definierten Menge der jeweiligen Mischkomponente vorgesehen ist. Eine Zuführleitung 20 ist mit ihrem einen Ende 22 an die Pumpe 16 angeschlossen. Eine Zuführleitung 24 ist mit ihrem einen Ende 26 an die Pumpe 18 angeschlossen. Das zweite Ende 28 derFigure 1 shows a schematic representation of an embodiment of the system 10 for exact dosing and homogeneous mixing of two liquid mixing components, which are each mounted in a container 12, 14. Each of the two containers 12, 14 is associated with a pump 16, 18, which is provided for dispensing a defined amount of the respective mixing component. A supply line 20 is connected at its one end 22 to the pump 16. A supply line 24 is connected at its one end 26 to the pump 18. The second end 28 of the
Zuführleitung 20 und das zweite Ende 30 der Zuführleitung 24 münden in eine Mischvorkammer 32 ein - wie auch aus Figur 2 deutlich ersichtlich ist -, die in Strömungsrichtung der beiden Mischkomponenten stromaufwärts an den statischen Mischer 34 angrenzt.Feed line 20 and the second end 30 of the supply line 24 open into a Mischvorkammer 32 a - as well as from Figure 2 is clearly visible - which adjoins upstream of the static mixer 34 in the flow direction of the two mixing components.
In der Mischvorkammer 32 ist ein Dispenser 36 vorgesehen.In the Mischvorkammer 32, a dispenser 36 is provided.
Die beiden Pumpen 16 und 18 stellen über einen großen Viskositäts- und Druckbereich der beiden in den Behältern 12 und 14 bevorrateten Mischkomponenten einen konstanten Volumenstrom derselben sicher. Von Wichtigkeit ist, dass die beiden Mischkomponenten beim Eintritt in die Mischvorkammer 32 die gleichen Eingangsdrücke besitzen, um unerwünschte pulsierende Volumenströme zu verhindern, aus welchen mangelhafte Dosierungen und inhomogene Mischungen der beiden Mischkomponenten resultieren würden. Dabei können die gleichen Eingangsdrücke der Mischkomponenten beim Eintritt in die Mischvorkammer 32 durch passende Dimensionierung der beiden Zuführleitungen 20 und 24 bestimmt sein. Desgleichen ist es möglich, dass die gleichen Eingangsdrücke der Mischkomponenten beim Eintritt in die Mischvorkammer 32 durch in den Zuführleitungen vorgesehene Drosseleinrichtungen 38 definiert eingestellt werden. Um Rückströmungen teilvermischter Mischkomponenten aus der Mischvorkammer 32 in die Zuführleitungen 20, 24 zu verhindern, können die Zuführleitungen 20, 24 eine Absperreinrichtung 40 aufweisen. The two pumps 16 and 18 provide over a large viscosity and pressure range of the two stored in the containers 12 and 14 Mixing components a constant volume flow of the same safe. It is important that the two mixing components have the same inlet pressures when entering the mixing prechamber 32, in order to prevent unwanted pulsating volume flows, which would result in deficient doses and inhomogeneous mixtures of the two mixing components. In this case, the same inlet pressures of the mixing components when entering the mixing pre-chamber 32 can be determined by appropriate dimensioning of the two supply lines 20 and 24. Likewise, it is possible that the same inlet pressures of the mixing components when entering the mixing pre-chamber 32 can be set defined by throttle means 38 provided in the feed lines. In order to prevent backflow of partially mixed components from the Mischvorkammer 32 in the supply lines 20, 24, the supply lines 20, 24 may have a shut-off device 40.
