Description

"Verfahren und Vorrichtung zur Herstellung von farbgesprenkeltem pulverförmi- gemSchüttg t""Method and device for the production of color-speckled powdered bulk"

Die Erfindung betrifft ein Verfahren zur Herstellung von farbgesprenkeltem pulverfόrmigen Schüttgut mit nichtfarbigen und farbigen Pulverbestandteilen sowie eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method for producing color-speckled powdery bulk material with non-colored and colored powder constituents and to an apparatus for carrying out this method.

Pulverförmige Schüttgüter, wie granulatförmige Wasch- und Reinigungsmittel werden wegen der optischen Anmutung teilweise mit einem geringen Anteil farbiger Pulverbestandteile vermischt. So werden beispielsweise weiße Wasch¬ oder Reinigergranulate durch Zudosierung von farbigen Granulaten optisch aufgewertet. Dabei können die Farbgranulate größere Korndurchmesser als das nichtfarbige, weiße oder helle Grundpulver haben. Die Korndurchmesser können aber auch gleichgroß sein.Powdery bulk goods, such as granular detergents and cleaning agents, are sometimes mixed with a small proportion of colored powder components due to their visual appearance. For example, white washing or cleaning granules are optically upgraded by metering in colored granules. The color granules can have larger grain diameters than the non-colored, white or light basic powder. The grain diameter can also be the same size.

Zur Herstellung von derart gesprenkelten Waschpulvern ist es derzeit üblich, zunächst ein weißes oder helles einfarbiges Pulver herzustellen. In einem separaten Herstellungsprozeß wird ein kräftig gefärbtes Pulver hergestellt. Die beiden Pulver werden dann in einem nachgeschalteten Schritt in dem gewünschten Verhältnis miteinander gemischt.For the production of detergent powders speckled in this way, it is currently customary to first produce a white or light, single-color powder. A strongly colored powder is produced in a separate manufacturing process. The two powders are then mixed with one another in the desired ratio in a subsequent step.

Die Erzeugung von zwei oder mehreren Pulvern unterschiedlicher Farbe erfordert jedoch ersichtlich einen hohen Herstellungsaufwand. Meist wird auf der gleichen Anlage weißes und farbiges Pulver nacheinander hergestellt, was zusätzlich mit einem erheblichen Reinigungsaufwand verbunden ist. Außerdem erfordert jedes zusätzliche Pulver vor der Mischung eine Zwischenlagerung mit entsprechend erheblichem Platzbedarf und muß mit hohen apparativem und/oder logistischem Aufwand transportiert werden.Obviously, the production of two or more powders of different colors requires a high manufacturing effort. Usually, white and colored powder are produced one after the other on the same system, which is also associated with a considerable cleaning effort. Moreover Each additional powder requires an intermediate storage before mixing with a correspondingly considerable space requirement and must be transported with high equipment and / or logistical effort.

Aufgabe der Erfindung ist es, eine Lösung zu schaffen, mit der farbgesprenkeltes pulverförmiges Schüttgut wesentlich einfacher hergestellt werden kann.The object of the invention is to provide a solution with which color-speckled powdery bulk material can be produced much more easily.

Diese Aufgabe wird mit einem Verfahren der eingangs bezeichneten Art erfindungsgemäß dadurch gelöst, daß zunächst nichtfarbiges pulverförmiges Schüttgut hergestellt wird und anschließend das nichtfarbige pulverförmige Schüttgut teilweise mit einer Farblösung besprüht wird.This object is achieved according to the invention with a method of the type mentioned at the outset by first producing non-colored powdery bulk material and then spraying some of the non-colored powdery bulk material with a color solution.

Erkennbar wird durch diese Verfahrensführung die Herstellung von farbgesprenkeltem pulverförmigen Schüttgut wesentlich vereinfacht. Es ist lediglich eine Anlage zur Herstellung von Schüttgut, also beispielsweise Wasch- oder Reinigungsmittel notwendig, in der lediglich nichtfarbiges, z.B. weißes Pulver hergestellt wird. Das so hergestellte Pulver wird dann anschließend lediglich teilweise dosiert besprüht, so daß sich die gewünschte Farbsprenklung einstellt. Eine dazu geeignete Zerstäubungseinrichtung läßt sich auf einfache Weise auch nachträglich beispielsweise in eine vorhandene Dosieranlage (z.B. Gemengeanlage einer Waschpulveraufbereituπg) einbauen oder vor- bzw. nachschalten.Obviously, the production of color-speckled powdery bulk material is significantly simplified by this process. All that is required is a plant for the production of bulk goods, for example washing or cleaning agents, in which only non-colored, e.g. white powder is produced. The powder thus produced is then only partially sprayed in a metered manner, so that the desired color sprinkling occurs. A suitable atomizing device can also be easily retrofitted, for example in an existing metering system (e.g. batch system of a washing powder preparation) or upstream or downstream.

Um ein besonders gutes und apparativ leicht erreichbares Farbspren- kelungsergebnis zu erzielen, ist vorteilhaft vorgesehen, daß das nichtfarbige pulverförmige Schüttgut als dosierter Pulverstrom gefördert und dabei von einer Oberflächenseite mit der Farblösung besprüht wird. Stromabwärts der Besprühung wird dann das so besprühte Pulver in üblicher Weise von der Fördereinrichtung des Dosierers abgeworfen, wodurch sich automatisch eine innige Vermischung mit den ungefärbten Pulveranteilen einstellt und die gewünschte Farbsprenkelung eintritt.In order to achieve a particularly good color sprinkling result that is easy to achieve in terms of apparatus, it is advantageously provided that the non-colored powdery bulk material is conveyed as a metered powder stream and is sprayed with the color solution from one surface side. Downstream of the spraying, the powder sprayed in this way is then thrown off in the usual way from the conveying device of the metering device, as a result of which a sets intimate mixing with the undyed powder and the desired color speckling occurs.

Zur Durchführung des vorbeschriebenen Verfahrens und zur Lösung der Aufgabe sieht die Erfindung auch eine Vorrich-tung vor, die eine Förder¬ einrichtung für pulverförmiges Schüttgut und wenigstens eine im Bereich der Fördereinrichtung angeordnete und diese beaufschlagende Zerstäubungsein¬ richtung für Farblösung aufweist. Eine solche Vorrichtung läßt sich auf relativ einfache Weise herstellen und auch in vorhandene Dosieranlagen einbauen, was ohne Schwierigkeiten auch nachträglich erfolgen kann.To carry out the above-described method and to achieve the object, the invention also provides a device which has a conveying device for powdery bulk material and at least one atomizing device for color solution which is arranged in the region of the conveying device and acts on it. Such a device can be manufactured in a relatively simple manner and can also be installed in existing metering systems, which can also be done subsequently without difficulty.

Vorteilhaft ist vorgesehen, daß die wenigstens eine Zerstäubungseinrichtung über eine Dosiereinrichtung mit einem Dosierbehälter für Farblösung verbun¬ den ist. Auf diese Weise läßt sich die gewünschte bzw. erforderliche Dosierung der Farbbestandteile leicht regulieren.It is advantageously provided that the at least one atomization device is connected via a metering device to a metering container for color solution. In this way, the desired or required dosage of the color components can be easily regulated.

In besonders vorteilhafter Ausgestaltung ist vorgesehen, daß die wenigstens eine Zerstäubungseinrichtung eine ultrafein zerstäubende Düse aufweist. Dadurch wird sichergestellt, daß das Pulver durch den ausgedüsten Strahl nicht hochgeblasen wird. Bei der Farbsprenkelung von Waschpulver hat sich z.B. eine Ultraschalldüse besonders gut bewährt. Die Farbaerosole des ausgedüsten Strahles werden dabei auf die Oberfläche eines dosierten Pulver¬ stromes oder auf den abfallenden Pulverstrom nach einem Pulverdosierer aufgetragen.In a particularly advantageous embodiment, it is provided that the at least one atomizing device has an ultra-fine atomizing nozzle. This ensures that the powder is not blown up by the sprayed jet. For example, the color speckling of washing powder has an ultrasonic nozzle has proven itself particularly well. The color aerosols of the sprayed jet are applied to the surface of a metered powder stream or to the falling powder stream after a powder metering device.

Dabei ist es besonders vorteilhaft, wenn die Fördereinrichtung als Dosierbandwaage ausgebildet ist. Da eine solche Dosiereinrichtung ohnehin benötigt wird, kann diese dann gleichzeitig auch zur Farbbesprühung benutzt werden, weil das Pulver beim dosierten Transport eine gut zu besprühende Oberfläche bietet. Die Erfindung ist nachstehend anhand der Zeichnung beispielsweise näher erläutert. Diese zeigt in einem vereinfachten Verfahrensfließbild eine Vorrich¬ tung zur Durchführung des erfindungsgemäßen Verfahrens.It is particularly advantageous if the conveyor is designed as a dosing belt scale. Since such a metering device is required anyway, it can also be used for spraying paint at the same time, because the powder provides a surface that is easy to spray during metered transport. The invention is explained below with reference to the drawing, for example. In a simplified process flow diagram, this shows a device for carrying out the method according to the invention.

Die Vorrichtung weist zunächst eine Fördereinrichtung 1 für pulverförmiges Schüttgut auf, die beim dargestellten Ausführungsbeispiel bevorzugt als Dosierbandwaage ausgebildet ist. Im Bereich des Anfangs dieser Förderein¬ richtung 1 ist ein Vorlagebunker 2 angeordnet, in welchem nichtfarbiges, z.B. weißes oder graues, pulverförmiges Schüttgut gelagert ist. Alternativ wäre es auch möglich, dieses nichtfarbige Schüttgut unmittelbar aus der Herstellungs¬ anlage (beispielsweise Waschmittelpulverherstellungsanlage) zuzuführen.The device initially has a conveying device 1 for powdery bulk material, which in the exemplary embodiment shown is preferably designed as a dosing belt scale. In the area of the beginning of this conveyor 1 there is a feed hopper 2 in which non-colored, e.g. white or gray, powdery bulk material is stored. Alternatively, it would also be possible to feed this non-colored bulk material directly from the production plant (for example detergent powder production plant).

Oberhalb der Fördereinrichtung 1 sind stromabwärts des Vorlagebunkers 2 eine Mehrzahl von neben- und/oder hintereinander angeordneten Zerstäu¬ bungseinrichtungen angeordnet, welche jeweils mit dem Bezugszeichen 3 gekennzeichnet sind.Above the conveying device 1, a plurality of atomizing devices arranged next to and / or one behind the other are arranged downstream of the feed hopper 2, each of which is identified by the reference number 3.

Diese Zerstäubungseinrichtungen 3 sind jeweils mit einer vorzugsweise ultrafein zerstäubenden Austrittsdüse 4 versehen, welche beispielsweise als Ultraschalldüse ausgebildet sein kann, was sich zur Besprühung von Wasch¬ mittelpulver besonders bewährt hat.These atomizing devices 3 are each provided with a preferably ultra-fine atomizing outlet nozzle 4, which can be designed, for example, as an ultrasonic nozzle, which has proven particularly useful for spraying detergent powder.

Die Zerstäubungseinrichtungen 3 sind über Zuleitungen 5 und Dosier- bzw. Regeleinrichtungen 5a mit einem Dosierbehälter 6 für Farblösung verbunden, in diesen Dosierbehälter 6 kann beispielsweise ein Rührwerk 7 integriert sein. Dieser Dosierbehälter 6 ist über eine Zuleitung 8 mit Förderpumpe 9 und Regelarmaturen 10 mit einem Farbansetzbehälter 11 verbunden, in welchem die gewünschte Farblösung zubereitet wird. Dazu wird in den Farbansetzbehälter 11 beispielsweise Farbpulver, was durch den Pfeil 12 angedeutet ist, und fluide Farbgrundsubstanz zugeführt, was durch den Pfeil 13 angedeutet ist. Außerdem kann der Farbansetzbehälter 11 mit einem Rührwerk 14 ausgerüstet sein.The atomization devices 3 are connected via feed lines 5 and metering or regulating devices 5a to a metering container 6 for color solution, for example an agitator 7 can be integrated in this metering container 6. This dosing container 6 is connected via a feed line 8 with a feed pump 9 and control fittings 10 to a paint preparation container 11, in which the desired color solution is prepared. For this purpose, for example, colored powder, which is indicated by the arrow 12, and fluid basic paint substance, which is indicated by the arrow 13, are fed into the paint preparation container 11. In addition, the paint preparation container 11 can be equipped with an agitator 14.

Zur Herstellung von farbgesprenkeltem pulverförmigen Schüttgut wird nun zunächst nichtfarbiges weißes oder graues pulverförmiges Schüttgut, also z.B. Wasch- oder Reinigungsmittel in üblicher Weise hergestellt und vorteilhaft im Vorlagebunker 2 zwischengelagert. Aus dem Vorlagebunker 2 wird dann auf der Dosierbandwaage 1 ein dosierter nichtfarbiger pulverförmiger Schütt¬ gutstrom gefördert, der von der Oberseite von den Zerstäubungseinrichtungen 3 mit Farblösung besprüht wird. Auf diese Weise wird die oberste Schicht des Pulverstromes eingefärbt und nach dem Abwurf des Schüttgutes von der Dosierbandwaage 1 erfolgt automatisch eine Vermischung der ungefärbten und gefärbten Pulveranteile und es steht das gewünschte farbgesprenkelte Schüttgut zur Verfügung.For the production of color-speckled powdery bulk material, first non-colored white or gray powdery bulk material, e.g. Detergents or cleaning agents are produced in the usual way and are advantageously stored temporarily in the storage bunker 2. A metered non-colored powdery bulk material flow is then conveyed from the feed hopper 2 on the dosing belt scale 1 and is sprayed with color solution from the top by the atomizing devices 3. In this way, the top layer of the powder stream is colored and after the bulk material has been ejected from the dosing belt scale 1, the undyed and colored powder components are automatically mixed and the desired color-speckled bulk material is available.

Natürlich ist die Erfindung nicht auf das dargestellte Ausführungsbeispiel beschränkt. Weitere Ausgestaltungen sind möglich, ohne den Grundgedanken zu verlassen. So kann das Schüttgut unter Verzicht auf den Vorlagebunker 2 auch kontinuierlich zugeführt werden. Of course, the invention is not limited to the exemplary embodiment shown. Further configurations are possible without leaving the basic idea. In this way, the bulk material can also be fed continuously without the feed hopper 2.
