AT 402 450 BAT 402 450 B
Die Erfindung betrifft eine Vorrichtung zum Dosieren von pulverförmigen Materialien und Wasser, umfassend einen kegelstumpfartigen vertikalen Behälter für pulverförmige Materialien, der mit einer Zerkleinerungsscheibe versehen ist, die von einer Schnecke mitgenommen wird, die eine bestimmte Pulvermenge transportiert,The invention relates to a device for metering powdery materials and water, comprising a truncated cone-like vertical container for powdery materials, which is provided with a comminution disk which is carried by a screw which transports a certain amount of powder,
Unter den derzeit zum Dosieren von Pulvern verwendeten Einrichtungen ist eine Vorrichtung bekannt, die eine Behandlungskammer aufweist, die mit einer ersten Schnecke mit einer Schraubenwendel versehen ist, die das Pulver aufgrund der Rotation der Schnecke verschiebt, wobei eine zweite Schnecke mit größerem Durchmesser mit offener Spirale, die koaxial in bezug auf die erste Schnecke angebracht ist, das Pulver konditioniert und in das Innere der ersten Schnecke zuführt, wobei eine der Schnecken einen Abschnitt umfaßt, der eine umgekehrte Steigung zur Steigung der anderen Schnecke aufweist, um eine Gegenstromverschiebung des Pulvers in der Kammer in bezug auf die Verschiebungsrichtung des Pulvers herbeizuführen, die durch die andere Schnecke bewirkt wird.Among the devices currently used for dosing powders, a device is known which has a treatment chamber which is provided with a first screw with a helical screw which displaces the powder due to the rotation of the screw, a second screw of larger diameter with an open spiral , which is coaxially mounted with respect to the first screw, conditions and feeds the powder to the inside of the first screw, one of the screws comprising a portion having an inverse slope to the slope of the other screw to countercurrently shift the powder in the To cause the chamber in relation to the direction of displacement of the powder caused by the other screw.
Es sind desgleichen Dosiersysteme bekannt, bei denen von der Fluidisierung des Pulvers Gebrauch gemacht wird. Bei diesen Systemen muß jedoch eine vollkommene Abdichtung sichergestellt sein. Die Realisierung dieser Abdichtung ist insbesondere dann schwierig, wenn sich die Anlagen außerhalb des Gebäudes befinden und außerdem von Benutzern ohne besondere Kenntnisse gehandhabt werden, was häufig bei Fahrzeugwaschanlagen der Fall ist.Dosing systems are also known in which use is made of the fluidization of the powder. With these systems, however, a perfect seal must be ensured. The implementation of this seal is particularly difficult when the systems are located outside the building and are also handled by users without special knowledge, which is often the case with vehicle washing systems.
Es ist ebenso bekannt, für Pulver, die grundsätzlich ein gutes Fließvermögen aufweisen, ein Dosiergerät zu verwenden, das eine horizontale, um ihre Achse drehbar montierte kreisförmige Platte umfaßt, die auf der Oberseite eine koaxiale kreisförmige Nut aufweist. Ein Versorgungs- oder Speisebehälter bzw. eine Schale ist oberhalb der Platte angeordnet und speist die Nut durch eine Ansaug- und Verteilungseinrichtung, die ebenso oberhalb der Platte angeordnet ist und unter Druck arbeitet. Bei unter Druck erfolgender Versorgung und Verteilung kann ein solches Dosiergerät lediglich arbeiten, wenn außerordentlich fluidisierte bzw. fließfähige Pulver verwendet werden, bei denen keine Kompaktierung erfolgt, und bei sehr geringen Durchsätzen.It is also known to use a metering device for powders, which generally have good fluidity, which comprises a horizontal circular plate which is rotatably mounted about its axis and which has a coaxial circular groove on the top. A supply or food container or a bowl is arranged above the plate and feeds the groove through a suction and distribution device, which is also arranged above the plate and works under pressure. When supplying and distributing under pressure, such a metering device can only work if extraordinarily fluidized or flowable powders are used, in which no compacting takes place, and at very low throughputs.
Durch die Erfindung ist hingegen eine Anwendung ins Auge gefaßt, bei der die Pulver aufgrund von Feuchtigkeit ein schlechtes Fließvermögen aufweisen und mit Durchsätzen in der Größe von einigen kg/h verteilt werden müssen. Hierbei kann das bekannte Dosiergerät deswegen nicht verwendet werden, weil das Pulver unter Druckeinwirkung eine Kompaktierung in der Nut und in der Ansaug- und Verteilungsvorrichtung erfährt.The invention, on the other hand, envisages an application in which the powders have poor fluidity due to moisture and have to be distributed with throughputs in the size of a few kg / h. The known metering device cannot be used here because the powder is compacted under pressure in the groove and in the suction and distribution device.
Außerdem ist diese bekannte Vorrichtung dazu vorgesehen, diskontinuierlich zu arbeiten, und es besteht Gefahr, daß sich Änderungen im Nenndurchsatz ergeben, die größer als die zulässige minimale Genauigkeit sind.In addition, this known device is intended to work discontinuously, and there is a risk of changes in the nominal throughput which are greater than the permissible minimum accuracy.
Mit der vorliegenden Erfindung wird bezweckt, die Nachteile und Unzulänglichkeiten der Dosiervorrichtungen nach dem aufgezeigtem Stand der Technik, nämlich die geringe Dosiergenauigkeit, das Erfordernis einer perfekten Dichtheit, die Unmöglichkeit einer fortlaufenden, kontinuierlichen Funktion und die Begrenzung auf die Verteilung mit zu geringem Durchsatz zu beheben. Die den Gegenstand der Erfindung bildende Vorrichtung ermöglicht eine genaue Dosierung von Pulver und Wasser.The present invention aims to remedy the disadvantages and inadequacies of the metering devices according to the prior art shown, namely the low metering accuracy, the requirement for perfect tightness, the impossibility of continuous, continuous function and the limitation to the distribution with too little throughput . The device forming the subject of the invention enables precise dosing of powder and water.
Da erfindungsgemäß zwischen dem Verteiler und dem Mischer kein weiterer Mechanismus bzw. keine weitere Vorrichtung vorgesehen ist, sondern das Pulver unter der Wirkung seines Eigengewichts vom Schneckenausgang direkt in den Mischer fällt, wird eine sehr große Zuverlässigkeit der Dosiervorrichtung erreicht.Since, according to the invention, no further mechanism or device is provided between the distributor and the mixer, but rather the powder falls directly into the mixer from the screw outlet under the effect of its own weight, the metering device is very reliable.
Die erfindungsgemäße Dosiervorrichtung ist dadurch gekennzeichnet, daß das Pulver im freien Fall in ein Wassergefäß fällt, das als Mischer und volumetrischer Dosierer fungiert, wobei die Schnecke am Ende eine vergrößerte Steigung aufweist, um einer Kompaktierung des Pulvers entgegenzuwirken, wobei weiters die Dosierung des Wassers durch einen Pegeldetektor erfolgt, der über ein Elektroventil kontinuierlich arbeitet, das eine Heißwassereinlaßleitung öffnet bzw. schließt, wobei weiters ein Mengenregler der Schnecke vorgesehen ist, um eine Pulverfüllung zu erhalten, die dem Öffnen und Schließen des Wasserventils proportional ist, um eine konstante Reinigungsmittelkonzentration unabhängig vom Wasser- bzw. Waschlösungsverbrauch zu erhalten, wobei das Gemisch über eine Hochdruckpumpe einer mobilen Waschlanze zugeführt wird.The dosing device according to the invention is characterized in that the powder falls in free fall into a water vessel which acts as a mixer and volumetric dosing device, the screw at the end having an increased pitch to counteract compacting of the powder, the water being further metered by a level detector takes place, which works continuously via an electrovalve that opens or closes a hot water inlet line, a flow regulator of the screw is also provided in order to obtain a powder filling that is proportional to the opening and closing of the water valve in order to maintain a constant detergent concentration regardless of To obtain water or washing solution consumption, the mixture being fed to a mobile washing lance via a high-pressure pump.
Es wird im folgenden eine Ausführungsform der Erfindung als nicht einschränkendes Beispiel und in Verbindung mit der Zeichnung detailliert beschrieben. In der Zeichnung zeigt: Fig. 1 eine schematische Axialschnittansicht, die das Funktionsprinzip der erfindungsgemäßen Dosiervorrichtung veranschaulicht.An embodiment of the invention is described in detail below as a non-limiting example and in conjunction with the drawing. The drawing shows: FIG. 1 a schematic axial sectional view which illustrates the functional principle of the metering device according to the invention.
Es wird im folgenden auf Fig. 1 Bezug genommen.Reference is made below to FIG. 1.
Die Pulverdosiervorrichtung umfaßt einen vertikalen Behälter 1 mit einer kegelstumpfförmigen Kammer 2, in der das Waschpulver aufgenommen wird.
