Description

Die vorstehende Erfindung betrifft eine Vorrichtung zum dosierten Verteilen einer Fluessigkeit aus einem Vorratsbehaelter an einen Aufnahmebehaelter.The above invention relates to a device for the metered distribution of a liquid from a storage container to a receiving container.

Behaelter und Vorrichtungen fuer die dosierte Verteilung von Fluessigkeit finden z.B. in Faerbereien Einsatz, um hier ein Faerbebad vorzubereiten. Auch in Laboratorien von Faerbereien finden derartige Geraete Einsatz, um Proben fuer die zu erstellenden Faerbebaeder vorzubereiten. Die dosierte Entnahme der Ausgangsstoffe, die in fluessiger Form in einer Anzahl von Vorratsbehaeltern gespeichert sind, erfolgt unter Verwendung von Misch- und Dosiereinrichtungen, die eine Entnahmevorrichtung aufweisen, deren Betrieb, z.B. ueber eine kleine Datenverarbeitungsanlage, gesteuert wird.Containers and devices for the metered distribution of liquid can be found e.g. in dye works to prepare a dye bath here. Such devices are also used in laboratories of dyeing companies to prepare samples for the dyeing baths to be created. The metered removal of the starting materials, which are stored in liquid form in a number of storage containers, is carried out using mixing and metering devices which have a removal device, the operation of which, e.g. is controlled via a small data processing system.

Es besteht auch die Moeglichkeit, den Materialentnahmevorgang von Hand zu steuern.It is also possible to control the material removal process by hand.

Fuer jeden Vorratsbehaelter, der mit einer Mischvorrichtung verbindbar ist, weist die Entnahmeeinrichtung einen Rohrstrang auf, ueber den ein unter Druck stehendes Gas, z.B. Druckluft, zufuehrbar ist. Des weiteren ist noch eine Rohrleitung vorgesehen, die mit einem absperrbaren Elektroventil ausgeruestet ist, ueber das die dosierte Entnahme der Fluessigkeit steuerbar ist.For every storage container with a mixing device is connectable, the removal device has a pipe string, via which a gas under pressure, for example compressed air, can be supplied. Furthermore, a pipeline is also provided, which is equipped with a lockable solenoid valve, via which the metered removal of the liquid can be controlled.

Die Materialentnahmerohre enden buendelartig ueber einem Behaelter zur Aufnahme der verschiedenen zu mischenden Stoffe.The material extraction tubes end in a bundle over a container to hold the various substances to be mixed.

Die Entnahmevorrichtungen, die ueblicherweise Form einer auf den Behaelter aufschraubbaren Kappe haben, weisen ueblicherweise eine Rohrleitung zum Zufuehren von Druckluft sowie eine Rohrleitung zur Entahme des zu mischenden Stoffes auf. Durch Zufuhr von Druckluft wird im Inneren der einzelnen Vorratsbehaelter ein Ueberdruck geschaffen, und die Entnahme der zu mischenden Stoffe erfolgt ueber eine Rohrleitung, in die ein steuerbares Elektroventil eingesetzt ist.The removal devices, which usually have the form of a cap that can be screwed onto the container, usually have a pipeline for supplying compressed air and a pipeline for extracting the substance to be mixed. By supplying compressed air, an overpressure is created in the interior of the individual storage containers, and the substances to be mixed are removed via a pipeline into which a controllable solenoid valve is inserted.

Vorrichtungen dieser Art sind aus dem Stand der Technik bekannt. Waehrend die bekannte Vorrichtung zum Entnehmen von Fluessigkeiten ein wirksames Hilfsmittel zum dosierten Verteilen unterschiedlicher Fluessigkeiten an verschiedene Behaelter darstellen, musste festgestellt werden, dass sich haeufig in den verschiedenen Vorratsbehaeltern Ablagerungen bilden, die selbst bei genauer Dosierung der verschiedenen Stoffe zu farblichen Unterschieden im Endprodukt, aufgrund der unvermeidlichen Ablagerungen in den Vorratsbehaeltern, fuehren. Um diesem Nachteil entgegenzuwirken, sind von Hand betaetigbare Ruehreinrichtungen bekanntgeworden, die mechanisch antreibbare, sich drehende Mischeinrichtungen aufweisen, die in die Fluessigkeit der einzelnen Vorratsbehaelter eingebracht werden und mit denen ein Durchmischen der im Vorratsbehaelter enthaltenen Fluessigkeit vor Durchfuehrung des Dosiervorganges moeglich ist.Devices of this type are known from the prior art. While the known device for removing liquids represents an effective aid for the metered distribution of different liquids to different containers, it had to be found that deposits often form in the various storage containers, even with precise metering of the different ones Lead fabrics to color differences in the end product due to the inevitable deposits in the storage containers. In order to counteract this disadvantage, manually operated stirring devices have become known which have mechanically drivable, rotating mixing devices which are introduced into the liquid of the individual storage containers and with which a mixing of the liquid contained in the storage container is possible before the metering process is carried out.

Dieser Mischvorgang ist von Hand durchzufuehren, erlaubt es aber nicht, den Misch- und Dosiervorgang zu automatisieren. Es ist aus dem Stand der Technik eine weitere Mischvorrichtung bekanntgeworden, die ein Fluegelrad aus magnetischem Werkstoff aufweist und von einem angetriebenen Magneten beeinflussbar ist, der z.B. unter dem Boden der einzelnen Vorratsbehaelter angeordnet ist.This mixing process must be carried out by hand, but does not allow the mixing and dosing process to be automated. A further mixing device has become known from the prior art, which has a vane wheel made of magnetic material and can be influenced by a driven magnet, which e.g. is arranged under the bottom of the individual storage container.

Diese motorisch angetriebene Vorrichtung, die fuer das Aufruehren einer zu verteilenden Fluessigkeit bekanntgeworden ist, hat den Nachteil, dass verschiedene, jeweils mit einem Antriebsmotor ausgeruestete Mischeinrichtungen vorzusehen sind, die mit Genauigkeit in einem Labortisch einzubauen sind. Daraus folgt, dass der technische Aufwand erheblich ist, ferner ist es erforderlich, saemtliche Vorratsbehaelter mit genau festgelegter Stellung gegenueber den magnetischen Einrichtungen anzuordnen. In vielen Faellen waere es hingegen von Vorteil, die einzelnen Vorratsbehaelter in beliebiger Weise um das Aufnahmegefaess herum anzuordnen.This motor-driven device, which has become known for stirring up a liquid to be distributed, has the disadvantage that different mixing devices, each equipped with a drive motor, are to be provided, which are to be installed with accuracy in a laboratory table. It follows from this that the technical outlay is considerable, and it is also necessary to arrange all the storage containers in a precisely defined position with respect to the magnetic devices. In many In contrast, it would be advantageous to arrange the individual storage containers in any way around the receptacle.

Es ist Aufgabe der vorstehenden Erfindung, die dem Stand der Technik anhaftenden Nachteile zu vermeiden und eine einfache Vorrichtung vorzuschlagen, mit der eine dosierte Entnahme von Fluessigkeiten aus Vorratsbehaeltern moeglich wird und die Vorrichtung auch ein Verruehren und Mischen der Fluessigkeit vor Durchfuehrung des Dosiervorganges ermoeglicht.It is an object of the above invention to avoid the disadvantages inherent in the prior art and to propose a simple device with which a metered removal of liquids from storage containers is possible and the device also enables the liquid to be mixed and mixed before the metering process is carried out.

Erfindungsgemaess wird diese Aufgabe dadurch geloest, dass die mit dem Vorratsbehaelter verbundene Entnahmevorrichtung eine Ausnehmung zur Aufnahme eines Turbinenrades aufweist, das von einem unter Druck stehenden Gasstrom beeinflussbar ist und mit dem Turbinenrad eine in den Vorratsbehaelter ragende Spindel wirkverbunden ist, die an ihrem freien Ende eine Misch- und Ruehreinrichtung aufweist.According to the invention, this object is achieved in that the removal device connected to the storage container has a recess for receiving a turbine wheel, which can be influenced by a pressurized gas flow, and a spindle projecting into the storage container, which has a free end at its free end, is operatively connected to the turbine wheel Has mixing and stirring device.

Mit besonderem Vorteil ist die Spindel der Turbine konzentrisch in einem Rohr gelagert, das fuer die Zufuehrung der Druckluft in das Innere des Behaelters dient.The spindle of the turbine is particularly advantageously mounted concentrically in a tube which is used to supply the compressed air into the interior of the container.

Weitere Vorteile der Erfindung koennen der folgenden Beschreibung, sowie den Unteranspruechen und den beigefuegten Zeichnungen entnommen werden.Further advantages of the invention can be found in the following description, as well as in the subclaims and the accompanying drawings.

Mit der Erfindung wird der Vorteil erzielt, dass der Druckluftstrom, der in das Innere des Vorratsbehaelters einzuleiten ist, um dort einen Ueberdruck zu schaffen, gleichzeitig dazu verwendet wird, die Mischeinrichtung anzutreiben. Gleichzeitig mit der Schaffung eines Ueberdruckes unter Verwendung eines unter Druck stehenden Gases wird auch die Mischeinrichtung angetrieben.With the invention, the advantage is achieved that the compressed air flow that into the interior of the storage container is to be initiated in order to create an overpressure there, at the same time it is used to drive the mixing device. Simultaneously with the creation of an excess pressure using a gas under pressure, the mixing device is also driven.

Die erfindungsgemaesse Einrichtung wird nun genauer anhand eines Ausfuehrungsbeispieles beschrieben und in den Zeichnungen dargestellt. Es zeigen:

  • Fig. 1 eine Ansicht der Einrichtung, zusammen mit einem Vorratsbehaelter; und
  • Fig. 2 die Vorrichtung nach Fig. 1 in vergroessertem Massstab und im Laengsschnitt.
The device according to the invention will now be described in more detail using an exemplary embodiment and shown in the drawings. Show it:
  • Figure 1 is a view of the device, together with a storage container. and
  • Fig. 2 shows the device of FIG. 1 on an enlarged scale and in longitudinal section.

Wie der Fig. 1 zu entnehmen ist, nimmt der Vorratsbehaelter 1 in seinem Inneren einen Fluessigkeitsvorrat 2 auf, von dem dosierte Mengen ueber ein Saugroehrchen 3 an einen (nicht dargestellten) Mischbehaelter zu foerdern sind. Ueber eine Leitung 4, die in die Vorrichtung 5 muendet, die nach Art einer Kappe auf den Behaelter 6 aufgeschraubt ist, kann ein unter Druck stehendes Gas in das Innere des Behaelters 6 gefoerdert werden, um im Behaelter 6 einen Ueberdruck P zu bilden. Mit dem Bezugszeichen 7 ist eine elektrische Leitung gekennzeichnet, ueber die ein Elektroventil (nicht dargestellt), das vom Stand der Technik bekannt ist, betaetigbar ist.As can be seen in FIG. 1, the storage container 1 accommodates in its interior a liquid supply 2, from which metered quantities are to be conveyed via a suction tube 3 to a mixing container (not shown). Via a line 4, which opens into the device 5, which is screwed onto the container 6 in the manner of a cap, a gas under pressure can be conveyed into the interior of the container 6 in order to form an excess pressure P in the container 6. The reference number 7 denotes an electrical line, via which an electrovalve (not shown), which is known from the prior art, can be actuated.

Das Elektroventil dient zum Steuern des Fluessigkeitsstromes vom Vorratsbehaelter zu einem Sammelbehaelter.The solenoid valve is used to control the flow of liquid from the storage container to a collecting container.

Das unter Druck stehende Gas wird ueber ein Roehrchen 4 zugefuehrt. Die bisher beschriebenen Einrichtungen sind vom Stand der Technik her bekannt.The gas under pressure is fed through a tube 4. The devices described so far are known from the prior art.

Um es zu ermoeglichen, waehrend der Entnahme der Fluessigkeit 2 auch ein Vermischen der Fluessigkeit vorzunehmen, ist in der deckelartig ausgebildeten Vorrichtung 5 eine Spindel 8 gelagert, die in den Behaelter 6 ragt. Am freien Ende der Spindel 8, das in unmittelbarer Naehe des Behaelterbodens 6 angeordnet ist, ist eine Mischeinrichtung 9, z.B. in Form eines Mischfluegels, vorgesehen. In der Naehe der Fluegel 9 ist auch die Oeffnung 3' des Saugroehrchens 3 angeordnet.In order to make it possible to also mix the liquid during the removal of the liquid 2, a spindle 8, which projects into the container 6, is mounted in the lid-like device 5. At the free end of the spindle 8, which is arranged in the immediate vicinity of the container bottom 6, there is a mixing device 9, e.g. in the form of a mixing wing. The opening 3 ′ of the suction tube 3 is also arranged near the wings 9.

Wie der Fig. 2 zu entnehmen ist, besteht die Vorrichtung 5 aus einer zylindrischen Kappe, die aus mehreren zusammengefuegten Bauteilen besteht.As can be seen from FIG. 2, the device 5 consists of a cylindrical cap, which consists of several assembled components.

In die Bauteile 10 und 11, die den Deckel der Vorrichtung 5 bilden, sind Ausnehmungen 12 und 13 eingearbeitet, die Kugellager 14 und 15 zur drehbaren Halterung der Spindel 8 aufnehmen.In the components 10 and 11, which form the lid of the device 5, recesses 12 and 13 are incorporated, which receive ball bearings 14 and 15 for rotatably holding the spindle 8.

Um zu vermeiden, dass die Spindel 8 waehrend der Drehbewegung zum Pendeln angeregt wird, ist auch im Koerper der Vorrichtung 5 eine Ausnehmung 16 vorgesehen, die ein weiteres Kugellager 17 aufnimmt. Im Bauteil 10 ist eine Ausnehmung 18 vorgesehen, die zur Aufnahme eines Turbinenrades 19 dient. Das Turbinenrad 19 wird ueber ein unter Druck stehendes Gas, das tangential zum Turbinenrad ueber die Leitung 4 zufgefuehrt wird, angetrieben. Somit wird, z.B. durch Zufuehren von Druckluft ueber die Leitung 4, das Turbinenrad 19 in Drehbewegung versetzt und demzufolge auch die Spindel 8 mit dem Mischgeraet 9 angetrieben.In order to avoid that the spindle 8 is excited to oscillate during the rotational movement, a recess 16 is also provided in the body of the device 5, which receives a further ball bearing 17. In the component 10, a recess 18 is provided, which is used to receive a Turbine wheel 19 is used. The turbine wheel 19 is driven by a gas under pressure, which is supplied tangentially to the turbine wheel via the line 4. Thus, for example by supplying compressed air via line 4, the turbine wheel 19 is rotated and consequently the spindle 8 is also driven with the mixing device 9.

Ferner ist ein Ausgang 30 in Wirkverbindung mit dem Raum 18, der das Turbinenrad 19 aufnimmt, vorgesehen. Somit besteht einmal die Moeglichkeit, den ueberschuessigen Luftstrom abzufuehren, und gleichzeitig eine Steuerung der Drehzahl der Mischeinrichtung 9 vorzunehmen.Furthermore, an output 30 is provided in operative connection with the space 18 which receives the turbine wheel 19. Thus, there is the possibility of removing the excess air flow and at the same time controlling the speed of the mixing device 9.

Wie der Zeichnung zu entnehmen ist, wird die Spindel 8 von einem Rohr 20 umgeben und ein Ende des Rohrstueckes steht mit dem Raum 13 in Wirkverbindung, der das Kugellager 15 aufnimmt. Das andere Ende des Rohres 20 steht mit der Kammer 16, die das Kugellager 17 aufnimmt, in Wirkverbindung. Somit wird das unter Druck stehende Gas, das ueber die Leitung 4 zugefuehrt wird, nach Antreiben des Turbinenrades 19 ueber das Lager 15 der Kammer 13 zugefuehrt und von dieser Kammer stroent das Gas ueber das Roehrchen 20 in die Kammer 16 und ueber das Kugellager 17 erreicht das verdichtete Gas eine Kammer 21, die mit dem Inneraum des Behaelters 6, der die Fluessigkeit 2 aufnimmt, in Verbindung steht.As can be seen in the drawing, the spindle 8 is surrounded by a tube 20 and one end of the tube piece is in operative connection with the space 13 which receives the ball bearing 15. The other end of the tube 20 is operatively connected to the chamber 16 which receives the ball bearing 17. Thus, the pressurized gas, which is supplied via line 4, is fed via the bearing 15 to the chamber 13 after driving the turbine wheel 19, and from this chamber the gas flows through the tube 20 into the chamber 16 and via the ball bearing 17 the compressed gas has a chamber 21 which communicates with the interior of the container 6 which holds the liquid 2.

Mit der beschriebenen Massnahme wird es einfach moeglich, im Inneren des Behaelters 6 den gewuenschten Ueberdruck P zu schaffen.With the measure described, it is easily possible to create the desired excess pressure P inside the container 6.

Um die Ansaugoeffnung 3' des Roehrchens 3 in unmittelbarer Naehe der Ruehr- und Mischvorrichtuing 9 am Ende der Spindel 8 vorsehen zu koennen, aber nicht mit dem Turbinenrad 19 in Beruehrung zu gelangen, das im Raum 18 gelagert ist, wird vorgesehen, dass das Ansaugroehrchen 3 im Inneren der Ausnehmung 21 eine Kroepfung 22 aufweist, die es ermoeglicht, das Ansaugende 3' des Saugrohres 3 im Behaelter 6 in unmittelbarer Naehe der Ruehreinrichtung 9 vorzusehen.In order to be able to provide the suction opening 3 'of the tube 3 in the immediate vicinity of the stirring and mixing device 9 at the end of the spindle 8, but not to come into contact with the turbine wheel 19 which is stored in the space 18, it is provided that the suction tube 3 in the interior of the recess 21 has a crank 22, which makes it possible to provide the suction end 3 'of the suction pipe 3 in the container 6 in the immediate vicinity of the stirring device 9.

Dadurch wird es moeglich, die Fluessigkeit 2 in unmittelbarer Naehe der Mischeinrichtung 9 zu entnehmen, wodurch gewaehrleistet wird, dass die entnommene Fluessigkeit stets gleichmaessige Mischung aufweist.This makes it possible to remove the liquid 2 in the immediate vicinity of the mixing device 9, which ensures that the liquid removed always has a uniform mixture.
