Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Farben und Lacken, bei dem Zwischenprodukte in einem Vorratsbehälter gelagert werden und das Zwischenprodukt in dem Vorratsbehälter mit einem Leitstrahlmischer gemischt wird. Weiterhin betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens mit einem Vorratsbehälter und einem in dem Vorratsbehälter angeordneten Leitstrahlmischer.The invention relates to a process for the production of paints and varnishes, in which intermediate products are stored in a storage container and the intermediate product in the storage container is mixed with a jet mixer. Furthermore, the invention relates to a device for carrying out the method with a reservoir and arranged in the reservoir Leitstrahlmischer.

Aus der DE 199 60 393 A1 ist ein Verfahren und eine Vorrichtung der eingangs genannten Art bekannt.From the DE 199 60 393 A1 a method and a device of the type mentioned is known.

Anstriche und Beschichtungssysteme werden bekanntermaßen auf Dissolvern und Inline-Dispergiermaschinen produziert. Dies ist für die Grundproduktionsprozesse ausreichend. In weiterentwickelten Verfahren werden zur prozesstechnischen Optimierung und zur zeitlichen Entkopplung der aufwendigen Produktionsmaschinen vom Korrektur- und Abfüllbetrieb grundproduzierte Rezepturen aus den Produktionsaggregaten in Lagerbehältern gelagert. In diesen wird ein zusätzliches Rührwerk beispielsweise in Form eines Leitstrahlmischers angeordnet, das eine Sedimentation der Feststoffe verhindert und die Flüssigkeit im Behälter weiter innig vermischt.Coatings and coating systems are known to be produced on dissolvers and inline dispersing machines. This is sufficient for the basic production processes. In further developed processes, basic-produced recipes from the production units are stored in storage containers for process engineering optimization and for temporal decoupling of the complex production machines from the correction and filling operation. In these an additional agitator is arranged, for example in the form of a jet mixer, which prevents sedimentation of the solids and further intimately mixes the liquid in the container.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Art zu schaffen, mit denen im Vorratsbehälter das Zwischenprodukt weiter entwickelt werden kann.The invention has for its object to provide a method and an apparatus of the type mentioned, with which the intermediate product can be further developed in the reservoir.

Die Lösung dieser Aufgabe erfolgt mit einem Verfahren mit den Merkmalen des Patentanspruchs 1. Vorrichtungsmäßig erfolgt die Lösung dieser Aufgabe mit einer Vorrichtung mit den Merkmalen des Patentanspruchs 9.The solution of this object is achieved with a method having the features of patent claim 1. In terms of device, the solution of this object is achieved with a device having the features of claim 9.

Bevorzugte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.Preferred embodiments of the invention are described in the subclaims.

Bei einem Verfahren zur Herstellung von Farben und Lacken, bei dem ein Zwischenprodukt in einem Vorratsbehälter gelagert wird und das Zwischenprodukt in dem Vorratsbehälter mit einem Leitstrahlmischer gemischt wird, ist erfindungswesentlich vorgesehen, dass das Mischen mit einem Unterspiegel-Leitstrahlmischer erfolgt, dass dem Zwischenprodukt über einen dem Unterspiegel-Leitstrahlmischer zugeordneten Zugang Komponenten zugeführt werden und dass die Komponenten in unmittelbarer Nähe zum Kopf des Unterspiegel-Leitstrahlmischers freigesetzt werden.In a process for the production of paints and varnishes, in which an intermediate product is stored in a reservoir and the intermediate product is mixed in the reservoir with a jet mixer, it is essential to the invention that the mixing takes place with a submirror-jet mixer, that the intermediate product via a the components associated with the submirror jet mixer are delivered and that the components are released in close proximity to the head of the submirror jet mixer.

Mit einem solchen Verfahren besteht die Möglichkeit auch kritische Komponenten zuzugeben. So ist eine schnelle Verteilung bei sichergestellter luftfreier Zuführung der Komponenten erreicht. Es handelt sich insbesondere um flüssige Komponenten. Diese werden luftfrei in das Zwischenprodukt eingebracht. Der Zugang ist durch einen Durchgang in der Wand des Vorratsbehälters geführt, der so tief ist, dass er vom Zwischenprodukt bedeckt ist.With such a method it is possible to add critical components as well. So a quick distribution is achieved with ensured air-free supply of the components. These are in particular liquid components. These are introduced into the intermediate product without air. The access is guided through a passage in the wall of the reservoir, which is so deep that it is covered by the intermediate product.

Bevorzugt werden als Komponenten Verdicker und/oder Lösungsmittel zugesetzt. Insbesondere für derartige kritische Komponenten, die möglichst rasch und ohne Luftzugaben in dem Zwischenprodukt verteilt werden müssen, ist das erfindungsgemäße Verfahren vorteilhaft. Das Verfahren ist insbesondere zur schnellen Verteilung flüssiger bis mittelviskoser Medien in große Volumina geeignet. Bevorzugt werden die Komponenten mit einer Pumpe in den Vorratsbehälter eingebracht. Diese ist einerseits erforderlich, um die Komponenten gegen den Mediendruck einbringen zu können. Andererseits kann mit einer Pumpe auch die Zuführleistung genau gesteuert oder geregelt werden.Thickeners and / or solvents are preferably added as components. In particular, for such critical components, which must be distributed as quickly as possible and without addition of air in the intermediate product, the inventive method is advantageous. The method is particularly suitable for the rapid distribution of liquid to medium-viscosity media in large volumes. The components are preferably introduced into the storage container by means of a pump. On the one hand, this is necessary in order to be able to introduce the components against the media pressure. On the other hand, with a pump and the feed can be precisely controlled or regulated.

Für derartige kritische Komponenten muss eine sofortige, aber gleichzeitig schonende Einarbeitung in das Zwischenprodukt erfolgen, um negative Produkteigenschaften wie Agglomerat oder Gelbildung sicher zu vermeiden. Dies gilt insbesondere dann, wenn als Zwischenprodukt ein Beschichtungssystem vorhanden ist.For such critical components an immediate, but at the same time gentle incorporation into the intermediate product must take place in order to reliably avoid negative product properties such as agglomeration or gelation. This is especially true when a coating system is present as an intermediate.

In einer bevorzugten Ausführungsform der Erfindung werden die Komponenten, die dem Zwischenprodukt zugesetzt werden, nur in sehr kleinen Dosierungen zugesetzt, d. h. insbesondere, dass das Verhältnis von Rohstoff zu Zwischenprodukt kleiner ist als 1:1000. Insbesondere kleiner ist als 1:5000.In a preferred embodiment of the invention, the components added to the intermediate are added only in very small dosages, i. H. in particular, that the ratio of raw material to intermediate product is less than 1: 1000. In particular, smaller than 1: 5000.

In einer besonders bevorzugten Ausgestaltung der Erfindung erfolgt die Zugabe der Komponenten in einem Zirkulationsbetrieb, bei dem das Zwischenprodukt aus dem Vorratsbehälter abgelassen und über den Zugang für die Komponente wieder zugeführt wird. Dabei können die Komponenten entweder als Vorlage oder besonders bevorzugt als permanente Zugabe in den Zirkulationskreislauf in den Vorratsbehälter eingebracht werden. Weiterhin ist es möglich, in dem Zirkulationskreislauf ein statisches Misch-element zu installieren, so dass bereits im Zirkulationskreislauf eine Vermischung des Zwischenprodukts mit der zuzumischenden Komponente erfolgt. Das Zwischenprodukt ist bevorzugt eine Farbe oder ein Lack.In a particularly preferred embodiment of the invention, the addition of the components takes place in a circulation operation, in which the intermediate product is discharged from the reservoir and fed back via the access for the component. In this case, the components can be introduced either as a template or more preferably as a permanent addition in the circulation circuit in the reservoir. Furthermore, it is possible to install a static mixing element in the circulation circuit, so that mixing of the intermediate product with the component to be admixed takes place already in the circulation circuit. The intermediate product is preferably a paint or a varnish.

Ein weiterer Aspekt der Erfindung betrifft die Verwendung des Verfahrens für die Zugabe von kritischen Komponenten wie Verdicker und Lösungsmittel in Farbe und/oder Lacke.Another aspect of the invention relates to the use of the method for the addition of critical components such as thickeners and solvents in paint and / or paints.

Bei einer Vorrichtung zur Herstellung von Farben und Lacken zur Durchführung des oben beschriebenen Verfahrens mit einem Vorratsbehälter und einem in dem Vorratsbehälter angeordneten Leitstrahlmischer ist erfindungswesentlich vorgesehen, dass der Leitstrahlmischer ein Unter-spiegel-Leitstrahlmischer ist, dass dem Unterspiegel-Leitstrahlmischer ein Zugang zur Zugabe von Komponenten zugeordnet ist und dass der Zugang in unmittelbarer Nähe des Kopfes des Unterspiegel-Leitstahlmischers endet. Mit dieser Vorrichtung kann das erfindungsgemäße Verfahren durchgeführt werden. In einem solchen Lager- oder Abfüllbehälter können eine beliebige Anzahl von Chargen aus der klassischen Fertigung verdichtet und direkt im Behälter, aus dem später abgefüllt wird, endkonfektioniert und sicher eingestellt werden. Unter der klassischen Fertigung wird hier die vorhergehende Fertigungsstufe in einem Dissolver oder einer Inline-Dispergiermaschine verstanden. Mit dieser Vorrichtung und dem damit betriebenen Verfahren können auch kritische Komponenten wie Lackinhaltsstoffe in aggregierten Ansätzen, also mit großem Volumina, im Vorratsbehälter sicher eingestellt werden. Die kapitalintensiven Produktionskapazitäten können besonders gut genutzt werden, da eine zeitkritische Nachstellung kritischer Komponenten in den Produkten nicht mehr zwingend im Dissolver oder in der Inline-Dispergiermaschine erfolgen muss, sondern in dem Vorratsbehälter durchgeführt wird.In a device for producing paints and varnishes for carrying out the method described above with a reservoir and arranged in the reservoir Leitstrahlmischer is essential to the invention that the Leitstrahlmischer is a sub-mirror Leitstrahlmischer that the Unterspiegel-Leitstrahlmischer an access to the addition of Assigned components and that the access ends in the immediate vicinity of the head of the lower mirror Leitstahlmischers. With this device, the inventive method can be performed. In such a storage or filling container any number of batches can be compacted from the classical production and directly in the container from which is filled later, assembled and safe be set. Conventional production is understood here to mean the preceding production stage in a dissolver or an inline dispersing machine. With this device and the process operated with it, critical components such as coating ingredients in aggregated approaches, ie with large volumes, can be safely adjusted in the reservoir. The capital-intensive production capacities can be used particularly well, since a time-critical adjustment of critical components in the products no longer necessarily must be done in the dissolver or in the inline dispersing machine, but is carried out in the reservoir.

Bevorzugt ist der Zugang als Impfnadel ausgebildet, wobei diese Impfnadel bevorzugt einen Durchmesser von 25 mm oder kleiner hat. Der Zugang ist dabei bevorzugt parallel zu der Welle des Unterspiegel-Leitstrahlmischers geführt. Der Zugang verwendet den selben Durchgang durch die Wand des Vorratsbehälters wie die Welle. Bevorzugt ist dem Zugang eine Pumpe zugeordnet, so dass die Komponenten durch die Pumpe über den Zugang in den Vorratsbehälter eingebracht werden. Der Zugang endet derart in der Nähe des Kopfes des Unterspiegel-Leitstrahlmischers, dass die hinzugefügten Komponenten in den Strahl eingezogen und dadurch sofort erfasst werden. Typische Abstände zum Kopf sind 5 bis 30 cm, bevorzugt 8 bis 20 cm.Preferably, the access is designed as a seed needle, this seed needle preferably has a diameter of 25 mm or smaller. The access is preferably guided parallel to the shaft of the sub-reflector jet mixer. The access uses the same passage through the wall of the reservoir as the shaft. Preferably, the access is associated with a pump, so that the components are introduced by the pump via the access into the reservoir. The access ends in the vicinity of the head of the submirror jet mixer such that the added components are drawn into the beam and thereby detected immediately. Typical distances to the head are 5 to 30 cm, preferably 8 to 20 cm.

In Fig. 1 ist ein Vorratsbehälter 1 dargestellt, der auch als Ablassbehälter bezeichnet wird und einen Ablass 5 aufweist. Der Ablassbehälter 1 hat eine Wandung 7 und ein nutzbares Volumen von 5 bis 30 m3, insbesondere 10 bis 20 m3. In den Vorratsbehälter 1 werden über eine hier nicht dargestellte Molchleitung vorproduzierte Zwischenprodukte aus einem Dissolver oder einer Inline-Dispergiermaschine eingebracht. In dem Vorratsbehälter 1 ist ein Unterspiegel-Leitstrahlmischer 2 angeordnet. Dieser weist einen Kopf 3 und eine Welle 4 auf. Die Welle 4 ist mit einem Durchgang 8 durch die Wand 7 des Vorratsbehälters 1 geführt. Der Unterspiegel-Leitstrahlmischer 2 ist vollständig im unteren Teil des Vorratsbehälters 1 angeordnet. Dadurch ist sichergestellt, dass durch die Verwendung des Unterspiegel-Leitstrahlmischers 2 keine Luft in das in dem Vorratsbehälter 1 beinhaltete Zwischenprodukt eindringen kann. Dem Unterspiegel-Leitstrahlmischer 2 ist ein Zugang 6 zugeordnet, der günstigerweise als Impfnadel ausgebildet ist und hier parallel und benachbart an der Welle 4 des Unterspiegel-Leitstrahlmischers 2 angeordnet ist. Der Zugang 6 endet unmittelbar und dicht benachbart vor dem Kopf 3 des Unterspiegel-Leitstrahlmischers 2. Der typische Abstand beträgt zwischen 5 und 30 cm, insbesondere zwischen 6 und 20 cm. Der Abstand zwischen dem Kopf des Zugangs 6 und dem Kopf 3 des Unterspiegel-Leitstrahlmischers 2 ist jedenfalls so klein, dass der durch den Zugang 6 eingebrachte Rohstoff bzw. die durch den Zugang 6 eingebrachten Komponenten sofort von dem Strahl des Unterspiegel-Leitstrahlmischers 2 angesaugt, erfasst und in dem Vorratsbehälter 1 verteilt werden. Die zugegebenen Komponenten sind hier in einem Container 12 gelagert und werden über eine Pumpe 9 und eine Zuführleitung 16 in den Vorratsbehälter 1 eingebracht. Die Pumpe 9 ist mit einem Ventil 10 zwischen Pumpe 9 und Vorratsbehälter 1 und einem Ventil 11 zwischen Container 12 und Pumpe 9 absperrbar.In Fig. 1 a storage container 1 is shown, which is also referred to as a discharge container and having a drain 5. The discharge container 1 has a wall 7 and a usable volume of 5 to 30 m 3 , in particular 10 to 20 m 3 . In the reservoir 1 pre-produced intermediates from a dissolver or an inline dispersing machine are introduced via a pig pipe not shown here. In the storage container 1, a lower mirror jet mixer 2 is arranged. This has a head 3 and a shaft 4. The shaft 4 is guided with a passage 8 through the wall 7 of the reservoir 1. The submirror jet mixer 2 is arranged completely in the lower part of the storage container 1. This ensures that no air can penetrate into the intermediate product contained in the storage container 1 through the use of the submirror jet mixer 2. The sub-reflector jet mixer 2 is associated with an access 6, which is conveniently designed as a seed needle and here parallel and adjacent to the shaft 4 of the sub-reflector jet mixer 2 is arranged. The access 6 ends immediately and closely adjacent to the head 3 of the submirror jet mixer 2. The typical distance is between 5 and 30 cm, in particular between 6 and 20 cm. In any case, the distance between the head of the access 6 and the head 3 of the submirror jet mixer 2 is so small that the raw material introduced by the access 6 or the components introduced through the access 6 are immediately drawn in by the jet of the submirror jet mixer 2, recorded and distributed in the reservoir 1. The added components are stored here in a container 12 and are introduced via a pump 9 and a supply line 16 into the reservoir 1. The pump 9 can be shut off with a valve 10 between the pump 9 and the reservoir 1 and a valve 11 between the container 12 and the pump 9.

In Fig. 2 ist eine weitere Ausführungsform der erfindungsgemäßen Vorrichtung dargestellt. Im Unterschied zu Fig. 1 werden hier Kleinstmengen zugesetzt. Diese können hier über einen Trichter 13 über Handzugabe in den Vorratsbehälter 1 eingebracht werden. Im Übrigen sind gleiche Teile mit gleichen Bezugszahlen wie in Fig. 1 gekennzeichnet, so dass insoweit auf die Beschreibung zu Fig. 1 Bezug genommen wird.In Fig. 2 a further embodiment of the device according to the invention is shown.

Ein Ausschnitt des Vorratsbehälters 1 mit der Behälterwand 7 ist in Fig. 4 dargestellt. Dargestellt ist der Abschnitt der Behälterwand 7, in dem der Unterspiegel-Leitstrahlmischer 2 aufgenommen ist. In der hier dargestellten Ausführungsform ist der Unterspiegel-Leitstrahlmischer 2 durch eine Turbine 20 gebildet, die mit einem Befestigungsgestänge 21 an der Behälterwand 7 befestigt ist. Der Durchgang durch die Wand 8 ist dabei nicht senkrecht zur Behälterwand 7 ausgebildet, sondern unter einem Winkel zu dieser, wobei der Unterspiegel-Leitstrahlmischer 2 schräg nach unten in den Vorratsbehälter 1 gerichtet ist und der Winkel zwischen dem Unterspiegel-Leitstrahlmischer 2, insbesondere zwischen der Welle 4 des Unterspiegel-Leitstrahlmischer 2 und der Behälterwand 7 zwischen 30° und 80°, insbesondere zwischen 40° und 70°, insbesondere zwischen 50° und 60° beträgt. Dies gilt auch für die oben beschriebenen Ausführungsbeispiele. Parallel zu der Welle 4 des Unterspiegel-Leitstrahlmischer 2 ist mit etwas Abstand innerhalb des Befestigungsgestänges 21 der Zugang 6 geführt, der als Impfnadel ausgebildet ist. Dieser endet im vorderen Bereich der Turbine 20, jedoch mit etwas Abstand zum vordersten Endbereich der Turbine 20. Die Turbine 20 erzeugt eine Strömung gemäß der Strömungspfeile 15. Aus der Impfnadel tritt die zugegebene Komponente gemäß dem Strömungspfeil 22 in den Vorratsbehälters 1 ein. Hier ist ein geringer Abstand zu dem Strömungspfeil 15 zu erkennen. Ein Motor 19 ist außerhalb des Vorratsbehälters 1 angeordnet und treibt die Welle 4 an, mit der die Turbine 20 betrieben wird. Die Behälterwand 7 ist im Durchgang 8 durch die Wand abgewinkelt, um auf diese Weise die Ausrichtung des Unterspiegel-Leitstrahlmischers 2 unter einem von 90° abweichenden Winkel zu ermöglichen.A section of the reservoir 1 with the container wall 7 is in Fig. 4 shown. Shown is the portion of the container wall 7, in which the sub-reflector jet mixer 2 is received. In the embodiment shown here, the submirror jet mixer 2 is formed by a turbine 20, which is fastened with a mounting linkage 21 on the container wall 7. The passage through the wall 8 is not formed perpendicular to the container wall 7, but at an angle to this, wherein the lower mirror jet mixer 2 is directed obliquely down into the reservoir 1 and the angle between the lower mirror jet mixer 2, in particular between the shaft 4 of the sub-reflector jet mixer 2 and the container wall 7 between 30 ° and 80 °, in particular between 40 ° and 70 °, in particular between 50 ° and 60 °. This also applies to the embodiments described above. Parallel to the shaft 4 of the submirror jet mixer 2, the access 6 is guided with some distance within the mounting rod 21, which is designed as a vaccination needle. This ends in the front region of the turbine 20, but with some distance to the foremost end of the turbine 20. The turbine 20 generates a flow according to the flow arrows 15. From the seed needle enters the added component according to the flow arrow 22 in the reservoir 1 a. Here, a small distance to the flow arrow 15 can be seen. A motor 19 is disposed outside of the reservoir 1 and drives the shaft 4, with which the turbine 20 is operated. The container wall 7 is angled in the passage 8 through the wall to allow in this way the orientation of the lower mirror jet mixer 2 at an angle other than 90 °.
