Abstract

The method involves providing an amount of diverse concentrate and an amount of diluents. The concentrate and the diluents are mixed. A ratio between the amount of concentrate and amount of diluents is kept constant by actuating two metering apparatuses with different flow rates per unit time for an equal length of time. Different concentrations of the solutions are produced by using concentrates with different concentrations. An independent claim is also included for an apparatus for producing diluted solutions in different concentrations.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung verdünnter Lösungen in unterschiedlichen Konzentrationen aus insbesondere verschiedenartigen Konzentraten, wobei jeweils eine Menge eines Konzentrates und eine Menge eines Verdünnungsmittels vermischt werden.The invention relates to a method and an apparatus for producing dilute Solutions in different concentrations of especially diverse Concentrates, each containing an amount of a concentrate and an amount of one Diluent are mixed.

Bei der Herstellung verdünnter Lösungen wird üblicherweise auf eine Volumseinheit des Konzentrates eine dem Verdünnungsfaktor entsprechende Vielzahl von Volumseinheiten des Verdünnungsmittels zugegeben.In the preparation of dilute solutions is usually based on a volume of the Concentrate a plurality of volume units corresponding to the dilution factor Diluent added.

Falls die verdünnten Lösungen unterschiedliche Konzentrationen aufweisen sollen, bleibt die Vorgangsweise dieselbe, d.h. für stärker verdünnte Lösungen werden mehr Volumseinheiten eines Verdünnungsmittels zugemischt.If the dilute solutions should have different concentrations, the Proceeding the same, i. for more dilute solutions will be more volume units a diluent mixed.

Diese im Prinzip völlig zufriedenstellende Vorgangsweise weist Nachteile auf, da Bemessungsfehler auftreten können. Diese bestehen hauptsächlich darin, dass das Volumen des Verdünnungsmittels falsch bestimmt, oder die Anzahl der Volumseinheiten falsch berechnet wird.This in principle completely satisfactory approach has disadvantages because Design errors can occur. These consist mainly in that the Volume of diluent incorrectly determined, or the number of volume units calculated incorrectly.

Die Fehler einer falschen Mengenbemessung treten wesentlich häufiger auf, als Fehler bei Herstellung von Konzentraten mit unterschiedlichen Konzentrationen, da die Mengenbemessung durch den Konsumenten bzw. Benützer erfolgt, während die Konzentrationseinstellung üblicherweise beim Hersteller des Konzentrates vorgenommen wird.The errors of a wrong quantity measurement occur much more frequently than errors Production of concentrates with different concentrations, as the Quantity measurement by the consumer or user takes place while the Concentration adjustment usually made by the manufacturer of the concentrate becomes.

So ist beispielsweise bei Reinigungs- oder Desinfektionsmitteln durch eine Zugabe einer Verschlusskappe des Mittels zu einem Eimer Wasser eine gleichbleibende Konzentration nahezu unmöglich, da weder der Wassereimer noch die Verschlusskappe immer mit gleichbleibenden Mengen gefüllt werden.For example, in cleaning or disinfecting agents by adding a Cap of the agent to a bucket of water a constant concentration almost impossible, since neither the water bucket nor the cap always with constant amounts are filled.

Zusätzlich tritt noch der Effekt auf, dass oft eine zusätzliche Portion des Konzentrates zugegeben wird, um die Wirkung sicherzustellen, was aber nicht erforderlich ist.In addition, the effect still occurs that often an additional portion of the concentrate is added to ensure the effect, but this is not required.

Die Falschdosierung wird beim enfindungsgemäßen Verfahren dadurch vermieden, dass das Verhältnis der beiden Mengen konstant gehalten wird und die unterschiedlichen Konzentrationen der verdünnten Lösungen dadurch hergestellt werden, dass Konzentrate mit unterschiedlichen Konzentrationen eingesetzt werden. Für den Benützer ergibt sich daher der Vorteil, dass die beiden Mengen von Konzentrat und Lösungsmittel in fixen Größen zur Verfügung gestellt werden, und er immer nur diese beiden Mengen vereinigen muss.The incorrect dosage is avoided in the inventive method in that the Ratio of the two quantities is kept constant and the different Concentrations of the dilute solutions are prepared by concentrates be used with different concentrations. For the user results Therefore, the advantage that the two amounts of concentrate and solvent in fixed Sizes are provided, and he always consolidates only these two quantities got to.

Des weiteren können für die Herstellung der unterschiedlich konzentrierten verdünnten Lösungen einfachere Dosier- bzw. Portioniervorrichtungen verwendet werden, die konstante Durchflussraten bzw. Portionen mit konstanten Volumina abgeben.Furthermore, for the preparation of the differently concentrated dilute Solutions simpler dosing or portioning devices are used, the constant Release flow rates or portions with constant volumes.

Beispielsweise kann ein Liter einer zehnprozentigen Lösung dadurch hergestellt werden, dass 10 Zentiliter Konzentrat und 90 Zentiliter Verdünnungsmittel vermischt werden. Eine hiefür geeignete Portioniervorrichtung weist zwei Behälter mit den genannten Rauminhalten auf. Diese Portioniervorrichtung kann ebenso zur Herstellung einer fünfprozentigen Lösung verwendet werden, die 95 Zentiliter Verdünnungsmittel enthalten muss. In diesem Fall wird ein um die Hälfte vorverdünntes Konzentrat eingesetzt, da die durch die Portioniervorrichtung ausgegebenen 10 Zentiliter des vorverdünnten Konzentrates bereits die auf 95 Zentiliter fehlenden 5 Zentiliter des Verdünnungsmittels enthalten.For example, one liter of a ten percent solution can be made thereby that 10 centiliters of concentrate and 90 centiliters of diluent are mixed. A For this purpose, suitable portioning device has two containers with said space contents on. This portioning device may also be used to prepare a five percent solution which must contain 95 centiliters of diluent. In this case will a half vorverdünntes concentrate used because of the Portioning device already spent 10 centiliters of prediluted concentrate contain 5 centiliters of the diluent missing on 95 centiliters.

Für größere Mengen werden bevorzugt, wie erwähnt, Dosiervorrichtungen mit konstanten Durchflussmengen pro Zeiteinheit gewählt. Zwanzig Liter der oben angegebenen zehnprozentigen Lösung werden durch Dosiervorrichtungen mit Durchflussraten von zwei Litern und achtzehn Litern pro Minute in einer Minute abgefüllt. Zwanzig Liter einer fünfprozentigen Lösung werden ebenfalls in einer Minute mittels dieser Dosiervorrichtungen hergestellt, wenn das Konzentrat um die Hälfte vorverdünnt ist und bereits ein ein Liter Verdünnungsmittel enthält.For larger quantities it is preferred, as mentioned, to have metering devices with constant Flow rates selected per unit time. Twenty liters of the above ten percent Solution are by metering devices with flow rates of two liters and eighteen liters per minute in one minute. Twenty liters of a five percent Solution are also prepared in one minute by means of these dosing devices, if the concentrate is prediluted by half and already one liter of diluent contains.

Von Bedeutung ist das erfindungsgemäße Verfahren vor allem, da in ein- und derselben Dosier- oder Portioniervorrichtung unterschiedliche Mittel verdünnt werden Können, die üblicherweise nicht in derselben Verdünnung angewendet werden. Es ist nur notwendig, die verschiedenen Mittel in gleichen, in die Vorrichtung einsetzbaren, austauschbaren Flaschen oder Behältern anzubieten.Of importance, the inventive method is especially because in one and the same Dosing or portioning device can be diluted different means that usually not used in the same dilution. It is only necessary that various means in the same, can be used in the device, interchangeable bottles or containers.
