Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von Farbe mit einer Anteigzone mit einer Misch- und Fördereinrichtung für das zugeführte trockene Farbpulver sowie das Wasser, wobei diese Misch- und Fördereinrichtung ein Misch- und Förderrohr mit einer darin angeordneten, drehbaren Welle aufweist, mit einer der Anteigzone nachgeordnete Mahlzone zum Zermahlen des mit dem Wasser versetzten Farbpulvers sowie mit einem der Mahlzone nachgeordneten Auslauf für die fertige Farbe.The invention relates to a device for producing paint with a dough zone a mixing and conveying device for the supplied dry color powder and the Water, this mixing and conveying device is a mixing and conveying pipe with a has rotatable shaft arranged therein, with one downstream of the rise zone Grinding zone for grinding the color powder mixed with the water as well as with a the outlet for the finished color after the grinding zone.

Dieser Stand der Technik ergibt sich aus der FR-A-969 933 (D2).This prior art results from FR-A-969 933 (D2).

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine zuverlässig arbeitende Vorrichtung zum Herstellen von Farbe zu schaffen, welche insbesondere die Entstehung von Farbklumpen vermeidet.Proceeding from this, the object of the invention is to create a reliably working device for producing color, which in particular avoids the formation of clumps of color.

Als technische Lösung wird mit der Erfindung vorgeschlagen,

  • a) daß an der Misch- und Fördereinrichtung (9) eine Wasserzuführung (8) angeordnet ist und
  • b) daß die Mahlzone (3) eine innerhalb des Misch- und Förderrohres (5) auf der drehbaren Welle (6) fest angeordnete, zylinderförmige Trommel (12) aufweist, deren beide Stirnwände (13) jeweils durch ein Lochblech oder Sieb gebildet sind und in deren Innern sich eine Vielzahl von zueinander beweglichen sowie in einer dichten Packung aneinanderliegenden Körper befinden, durch die hindurch die angeteigte Farbe hindurchleitbar ist.
    • The invention proposes as a technical solution
  • a) that a water supply (8) is arranged on the mixing and conveying device (9) and
  • b) that the grinding zone (3) within the mixing and delivery pipe (5) on the rotatable shaft (6) fixedly arranged, cylindrical drum (12), the two end walls (13) of which are each formed by a perforated plate or sieve and in the interior of which there are a large number of bodies which are movable relative to one another and lie in a tight packing against one another and through which the pasted paint can be passed.

    • Dadurch ist ein automatisch arbeitender Farbmischer geschaffen, mittels dem vor allem eine kontinuierliche Herstellung von Farbe möglich ist, so daß das zugeführte trockene Farbpulver nach dem Vermischen mit Wasser kontinuierlich und ohne Unterbrechungen beispielsweise auf einer Fassade aufgebracht werden kann. Die Grundidee der erfindungsgemäßen Herstellungsvorrichtung besteht darin, daß mittels einer entsprechenden Einrichtung zunächst das zu verarbeitende trockene Farbpulver der Herstellungsvorrichtung zugeführt wird. In einem ersten Schritt wird in der Anteigzone das trockene Farbpulver zunächst mit Wasser vermischt, so daß eine Art Teig oder Brei entsteht. Die Welle ist dabei innerhalb des Misch- und Förderrohres drehbar gelagert und weist für den Mischvorgang entsprechende Mischpaddel oder vergleichbare Einrichtungen sowie für die Förderung des Teigs oder Breies Transportpaddel beispielsweise in Form von schräggestellten Flügeln auf. Statt dieser Transportpaddel ist es selbstverständlich auch denkbar, andere Transporteinrichtungen einzusetzen, beispielsweise eine Förderschnecke. Der Teig oder Brei wird im Anschluß an die Anteigzone gleichzeitig während des Mischvorganges der nachgeordneten Mahlzone zugeführt, wo der Teig oder Brei dann zermahlen und damit homogenisiert wird, um auf diese Weise dann die fertige flüssige Farbe mit der üblichen herkömmlichen Konsistenz zu erhalten. Die Grundidee der Mahleinrichtung besteht darin, eine Vielzahl von losen Körpern vorzusehen, welche insbesondere durch Bewegen eines entsprechenden Aufnahmebehälters gegeneinander bewegt werden. Die aneinandergleitenden sowie aufeinander abrollenden Körper definieren somit zwischen sich jeweils kleine Mahl- und Mischeinheiten mit der Folge, daß der Farbteig oder Farbbrei zwischen den Körpern gemahlen und gemischt wird, so daß schließlich in einer homogen gleichmäßigen Konsistenz die flüssige Farbe entsteht. Der Mahl- und Durchmischungsgrad hängt natürlich von der Länge der Mahlzone sowie von der Durchtrittsgeschwindigkeit der Farbe ab. Die Grundidee besteht somit darin, die Trommel insbesondere mit Kugeln zu füllen und dabei diese Trommel in eine Drehbewegung zu versetzen, so daß die Kugeln ständig bewegt und umgeschichtet werden und somit den Mahlvorgang ermöglichen. Die Trommel wird dabei einen geschlossenen Zylindermantel aufweisen, während die beiden Stirnseiten Öffnungen aufweisen, wobei die eine Stirnseite als Eintritt für die angeteigte Farbe und die andere Stirnseite als Austritt für die fertige flüssige Farbe dient. Die Lochbleche oder Siebe für die Stirnwände weisen dabei entsprechende Öffnungen auf, deren Durchmesser selbstverständlich kleiner ist als die Durchmesser der Kugeln. Die Trommel ist dabei innerhalb des Misch- und Förderrohres auf der Welle fest angeordnet. Dies bedeutet, daß, wenn in der Anteigzone sich die Welle dreht und somit der Farbteig oder Farbbrei gebildet wird, die Trommel in der Mahlzone gleichzeitig und synchron mitdreht. Der Vorteil liegt darin, daß die Welle zusammen mit der Trommel eine bauliche Einheit bildet, ebenso wie das Misch- und Förderrohr, welches sich nicht nur in der Anteigzone befindet, sondern auch in der Mahlzone, wo es allerdings im Vergleich zur Anteigzone zur Aufnahme der Trommel einen erheblich größeren Durchmesser aufweist. Die fertige Farbe kann dann über den Auslauf ausgetragen werden, indem die flüssige Farbe beispielsweise abgepumpt und gleich verarbeitet wird. Es handelt sich somit erfindungsgemäß um eine mehrstufige Anlage, bei der zunächst ein Teig oder Brei hergestellt wird, welcher dann durch einen Mahlvorgang vergleichmäßigt wird.This creates an automatically working color mixer, by means of which above all a continuous production of color is possible, so that the supplied dry Color powder after mixing with water continuously and without interruptions for example, can be applied to a facade. The basic idea of the invention Manufacturing device is that by means of an appropriate device the dry paint powder to be processed is first fed to the production device becomes. In a first step, the dry color powder is first in the dough zone mixed with water to form a kind of dough or porridge. The wave is there rotatably mounted within the mixing and delivery pipe and points for the mixing process Appropriate mixing paddles or comparable facilities as well as for the promotion of Dough or porridge transport paddles, for example in the form of inclined wings. Instead of this transport paddle, it is of course also conceivable to use other transport devices use, for example, a screw conveyor. The dough or porridge is in the Connection to the dough zone at the same time during the mixing process of the downstream Fed into the grinding zone, where the dough or porridge is then ground and thus homogenized, to get the finished liquid color with the usual conventional consistency to obtain. The basic idea of the grinding device is to make a lot of loose Provide bodies, which in particular by moving a corresponding receptacle be moved against each other. The one sliding against each other as well rolling bodies thus define small grinding and mixing units between them with the result that the colored paste or pulp is ground and mixed between the bodies is, so that finally the liquid in a homogeneously uniform consistency Color emerges. The degree of grinding and mixing naturally depends on the length of the Grinding zone and the speed at which the paint passes. The basic idea is there thus, in particular to fill the drum with balls and thereby this drum in to set a rotational movement so that the balls are constantly moved and shifted and thus enable the grinding process. The drum is closed Have cylinder jacket, while the two end faces have openings, one end as entry for the pasted color and the other end as Exit serves for the finished liquid paint. The perforated sheets or screens for the end walls have corresponding openings, the diameter of which is of course smaller is than the diameter of the balls. The drum is inside the mixing and delivery pipe firmly arranged on the shaft. This means that when in the dough zone the shaft rotates and thus the dough or pulp is formed, the drum in the Grinding zone rotates simultaneously and synchronously. The advantage is that the shaft is together forms a structural unit with the drum, just like the mixing and delivery pipe, which is not only in the dough zone, but also in the grinding zone where it however, in comparison to the dough zone for receiving the drum, a considerably larger one Has diameter. The finished color can then be discharged through the outlet be pumped out, for example, by the liquid paint and processed immediately. It is therefore, according to the invention, a multi-stage system, in which initially a dough or porridge is produced, which is then evened out by a grinding process.

    Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen. Advantageous further developments result from the subclaims.

    Vorzugsweise sind die Körper Kugeln und bestehen beispielsweise aus Glas, Metall, Keramik oder einem anderen geeigneten festen Material. Die Kugeln haben den Vorteil, daß sie sehr gut aufeinander abrollen können und somit einen optimalen Zermahlwirkungsgrad erzielen.The bodies are preferably spheres and consist, for example, of glass, metal, ceramic or other suitable solid material. The balls have the advantage that they can roll on each other very well and thus achieve an optimal grinding efficiency.

    Eine weitere Weiterbildung der Trommel schlägt vor, daß diese in Segmente unterteilt ist, wobei die Trennwände vorzugsweise aus einem Lochblech oder Sieb bestehen. Die Trommel weist somit bezüglich der Mittelachse radiale Trennwände auf, welche die Trommel in einzelne Kammern unterteilen, in denen sich jeweils eine Kugelpackung befindet. Dabei können die Trennwände mit Öffnungen versehen sein, die zwar einen Durchtritt der Farbe ermöglichen, nicht jedoch einen Durchtritt der Kugeln. Der Vorteil der Trommelsegmente liegt darin, daß die Kugeln in ihrem jeweiligen Segment eine gewisse räumliche Begrenzung aufweisen. Vor allem aber haben die Trommelsegmente den Vorteil, daß sich die Farbe nicht aufgrund der Schwerkraft im unteren Bereich sammelt. Durch die Segmentierung ist die Trommel gleichmäßig mit Farbe gefüllt.A further development of the drum suggests that it be divided into segments, the partitions preferably consist of a perforated plate or sieve. The drum thus has radial partitions with respect to the central axis which the drum in divide individual chambers, each containing a ball packing. Here the partitions can be provided with openings that allow the color to pass through allow, but not a passage of the balls. The advantage of the drum segments lies in the fact that the spheres have a certain spatial limitation in their respective segment exhibit. Above all, the drum segments have the advantage that the color does not collect due to gravity in the lower area. Because of the segmentation the drum filled evenly with paint.

    Die Mahlzone kann in einer optionalen Weiterbildung eine zusätzliche Wasserzuführung aufweisen, um den in der Anteigzone hergestellten Farbteig weiter mit Wasser zu verdünnen. Dabei kann diese zusätzliche Wasserzuführung auch dazu benutzt werden, um die Eintrittsstirnseite der Trommel kontinuierlich zu reinigen. Selbstverständlich kann aber auch auf diesen zusätzlichen Wassereintrag verzichtet werden.In an optional development, the grinding zone can have an additional water supply, to further dilute the color dough made in the dough zone with water. This additional water supply can also be used to the front face to clean the drum continuously. Of course, but can also on this additional water entry can be dispensed with.

    Eine weitere Weiterbildung der erfindungsgemäßen Herstellungsvorrichtung für Farbe schlägt vor, daß ein Auslaufstutzen des Auslaufs drehbar gelagert ist und dadurch der erforderliche Füllstand im Mischer anpaßbar ist. Another development of the manufacturing device for color according to the invention suggests that a spout of the spout is rotatably mounted and thereby the required Level in the mixer is adjustable.

    Eine weitere Weiterbildung schlägt vor, daß zwischen der Anteigzone und der Mahlzone eine zusätzliche Fördereinrichtung für das angeteigte Farbpulver angeordnet ist. Dies hat den Vorteil, daß das in der Anteigzone angeteigte Farbpulver ohne Staubildung der Mahlzone zugeführt wird, so daß ein kontinuierlicher Abtransport des angeteigten Farbpulvers stattfindet.Another development suggests that between the dough zone and the grinding zone additional conveyor for the pasted paint powder is arranged. This has the Advantage that the pasted paint powder without dusting the grinding zone is supplied so that a continuous removal of the pasted color powder takes place.

    Vorzugsweise besteht die Fördereinrichtung aus feststehenden sowie schräggestellten Schermessern. Dadurch ist zwischen der Anteigzone und der Mahlzone eine Scherzone mit wenigstens vier Schermessern zusätzlich geschaffen. Das in einer Drehbewegung sich befindende angeteigte Farbpulver erfährt durch die bezüglich der Längsachse der Welle schräggestellten Schermesser eine Axialkomponente, welche für den Vorwärtstransport des angeteigten Farbpulvers sorgt. Um einen gleichmäßigen Transport zu erzielen, sind die Schermesser vorzugsweise um den gesamten Umfang herum gleichmäßig verteilt. Im Bereich dieser Schermesser kann auch die bereits erwähnte zusätzliche Wasserzuführung liegen.The conveyor preferably consists of fixed and inclined ones Shear knives. This means that there is a shear zone between the dough zone and the grinding zone created at least four additional shear blades. The one that is rotating pasted color powder experiences through the with respect to the longitudinal axis of the shaft inclined shear knife an axial component, which is for the forward transport of the pasted color powder. To achieve even transport, they are Shear knives preferably evenly distributed around the entire circumference. In the area this shear knife can also be the already mentioned additional water supply.

    Schließlich wird in einer Weiterbildung vorgeschlagen, daß zwischen der Mahlzone und dem Auslauf eine zusätzliche Misch- und Transporteinrichtung vorgesehen ist. Diese Misch-und Transporteinrichtung kann durch die durchgehende Welle gebildet sein, welche mit entsprechenden Misch- und Transportpaddeln ausgestattet ist.Finally, it is proposed in a further development that between the grinding zone and the Spout an additional mixing and transport device is provided. This mixing and Transport device can be formed by the continuous shaft, which with corresponding Mixing and transport paddles is equipped.

    Im Bereich der Scherzone 2 weist das Misch- und Förderrohr 5 im Bereich der innenseitigen Stirnwand flügelartige sowie schräggestellte Schermesser 10 auf, welche um den Umfang herum gleichmäßig verteilt sind. Diese Schermesser 10 definieren eine Fördereinrichtung 11 für das aus der Anteigzone 1 angeteigte Farbpulver hin zur nachfolgenden Mahlzone 3.In the area of the shear zone 2, the mixing and delivery pipe 5 points in the area of the inside Front wall wing-like and inclined shear blades 10, which around the circumference are evenly distributed around. These shear blades 10 define a conveyor 11 for the color powder made from pasting zone 1 to the subsequent grinding zone 3.

    Die Mahlzone 3 ist durch eine zylinderförmige Trommel 12 gebildet, welche auf der Welle 6 fest angeordnet ist. Während die Zylindermantelfläche dieser Trommel 12 geschlossen ist, sind die beiden Stirnwände 13 der Trommel 12 jeweils mit Öffnungen versehen und beispielsweise durch ein Lochblech oder ein Sieb gebildet. Im Innern der Trommel 12 sind noch radiale Trennwände 14 angeordnet, welche ebenfalls durch Lochbleche gebildet sind und die Trommel in einzelne Segmente 15 unterteilen. Diese sind jeweils mit Kugeln 16 aus Glas, Metall, Keramik oder einem anderen geeigneten harten Material gefüllt. Der Durchmesser dieser Kugeln 16 ist selbstverständlich größer als der Durchmesser der Öffnungen in den Stirnwänden 13 sowie in den Trennwänden 14. Schließlich weist das Misch-und Förderrohr 5 im Bereich der Mahlzone 3 noch zwei Wasserzuführungen 17 auf, welche allerdings nicht unbedingt vorhanden sein müssen.The grinding zone 3 is formed by a cylindrical drum 12, which is on the shaft 6 is firmly arranged. While the cylindrical surface of this drum 12 is closed, the two end walls 13 of the drum 12 are each provided with openings and, for example formed by a perforated plate or a sieve.

    Innerhalb des Auslaufstutzens 18 ist die Welle 6 mit Misch- und Transportpaddeln 19 versehen, welche eine zusätzliche Misch- und Transporteinrichtung 20 definieren.Within the outlet nozzle 18, the shaft 6 is provided with mixing and transport paddles 19, which define an additional mixing and transport device 20.

    Der Farbmischer funktioniert wie folgt:The color mixer works as follows:

    Die Welle 6 mit ihren Misch- und Förderpaddeln 7, 19 sowie mit ihrer Trommel 12 wird in eine Drehbewegung versetzt, so daß sich der Farbmischer im Betriebszustand befindet. Der Anteigzone 1 wird trockenes Farbpulver zugeführt, was durch den Pfeil P schematisch angedeutet ist. Das trockene Farbpulver wird von den Misch- und Förderpaddeln 7 erfaßt und dabei mit dem durch die Wasserzuführung 8 zugeführten Wasser vermischt und dabei der Scherzone 2 zugeführt. In dieser Anteigzone 1 wird dem dosiert zugeführten Farbpulver soviel Wasser zugeführt, daß ein Teig entsteht, der durch die Misch- und Förderpaddel 7 angerührt wird.The shaft 6 with its mixing and conveying paddles 7, 19 and with its drum 12 is in one Rotational movement offset so that the paint mixer is in the operating state. Of the Dough zone 1 is supplied with dry color powder, which is indicated schematically by the arrow P. is. The dry paint powder is detected by the mixing and conveying paddles 7 and mixed with the water supplied through the water supply 8 and the Shear zone 2 fed. In this dough zone 1 there is so much dosed powder powder Water supplied that a dough is formed, which is mixed by the mixing and conveying paddles 7 becomes.

    Dieser Brei gelangt in die Scherzone 2 und wird durch die fest angeordneten und schrägstehenden Schermesser 10 nach vorne befördert, so daß der Brei durch die Stirnwand 13 in Form des Lochbleches in die Segmente 15 der Trommel 12 gelangt. Über die Wasserzuführungen 17 kann dabei weiter Wasser zugeführt werden, so daß ein Brei entsteht.This pulp enters the shear zone 2 and is due to the fixed and sloping Shear knife 10 conveyed forward so that the slurry through the end wall 13 in Shape of the perforated plate reaches the segments 15 of the drum 12. About the water supply 17 can continue to be supplied water, so that a porridge is formed.

    In den Segmenten 15 der Trommel 12 erfolgt durch das ständige Umwälzen der Kugeln 16 ein Mahlen und Mischen des Farbbreis, so daß nach erfolgter Homogenisierung die flüssige Farbe entsteht. Diese flüssige Farbe tritt durch die ausgangsseitige Stirnwand 13 der Trommel 12 hindurch und gelangt dort in die Misch- und Transporteinrichtung 20 im Auslauf 4, von wo aus die fertige flüssige Farbe abgepumpt und der Verbrauchsstelle zugeführt werden kann. In the segments 15 of the drum 12, the balls 16 are continuously circulated a grinding and mixing of the pulp, so that the liquid after homogenization Color emerges. This liquid paint passes through the outlet end wall 13 of the drum 12 and passes there into the mixing and transport device 20 in the outlet 4, from where the finished liquid paint is pumped out and fed to the point of use can.
