Definitions
- the invention relates to a device for producing paint, wherein dry paint powder is mixed with water.
- the object of the invention is to create an easy-to-use device for producing color, by means of which, in particular, continuous color production is also possible.
- the technical solution is characterized by a dough zone with a mixing and conveying device for the supplied dry paint powder and with a water supply arranged on the mixing and conveying device, further by a grinding zone downstream of the dough zone for grinding the paint powder mixed with the water and finally by a the outlet for the finished color after the grinding zone.
- the dry color powder to be processed is first fed to the manufacturing device by means of an appropriate device.
- the dry color powder is first mixed with water in the dough zone, so that a type of dough or porridge is formed, which is simultaneously fed to the downstream grinding zone during the mixing process, where the dough or porridge is then ground and thus homogenized in order to in this way to obtain the finished liquid color with the usual conventional consistency.
- This finished paint can then be discharged through the outlet, for example by pumping off the liquid paint and processing it immediately.
- it is therefore a multi-stage system, in which a dough or porridge is first produced, which is then evened out by a grinding process.
- the dough zone preferably has a mixing and conveying tube with a shaft arranged therein and with the water supply.
- the shaft is thus rotatably mounted within the mixing and conveying tube and has corresponding mixing paddles or comparable devices for the mixing process and transport paddles for conveying the dough or slurry, for example in the form of inclined blades.
- this transport paddle it is of course also conceivable to use other transport devices, for example a screw conveyor.
- a further development of the manufacturing device according to the invention proposes that the water supply quantity can be controlled as a function of the color powder delivery quantity. This means that a well-dosed and fixed amount of water is always added to the conveyed paint powder, so that the paint automatically receives the desired water content.
- this consists of a plurality of bodies which are moved towards one another and lie in a tight packing against one another, through which the pasted paint can be passed.
- the basic idea of the grinding device designed in this way is to provide a large number of loose bodies, which are moved against one another in particular by moving a corresponding receptacle.
- the bodies sliding against one another and rolling on one another 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, so that the liquid color is ultimately produced in a homogeneously uniform consistency.
- the degree of grinding and mixing naturally depends on the length of the grinding zone and the speed at which the paint passes.
- the bodies are preferably spheres and consist, for example, of glass, metal, ceramic or another suitable solid material.
- the balls have the advantage that they can roll on each other very well and thus achieve an optimal grinding efficiency.
- the bodies are arranged in a rotatable, cylindrical drum, the two end walls each being formed by a perforated plate or sieve.
- the basic idea is to make such a drum in particular to fill with balls and to set this drum in a rotary motion so that the balls are constantly moved and shifted and thus enable the grinding process.
- the drum will have a closed cylinder jacket, while the two end faces have openings, one end face serving as an inlet for the pasted paint and the other end face serving as an outlet for the finished liquid paint.
- the perforated plates or screens for the end walls have corresponding openings, the diameter of which is of course smaller than the diameter of the balls.
- a preferred constructive design of the drum suggests that it is fixedly arranged on the shaft within the mixing and delivery pipe. This means that when the shaft in the dough zone rotates and the color paste or pulp is formed, the drum in the grinding zone rotates simultaneously and synchronously.
- the advantage lies in the fact that the shaft forms a structural unit together with the drum, just like the mixing and conveying pipe, which is not only located in the dough zone, but also in the grinding zone, where, however, in comparison to the dough zone for receiving the Drum has a significantly larger diameter.
- a further development of the drum suggests that it be divided into segments, the partitions preferably consisting of a perforated plate or sieve.
- the drum thus has radial partition walls with respect to the central axis, which divide the drum into individual chambers, in each of which there is a ball packing.
- the partitions can be provided with openings which allow the paint to pass through, but not through the balls.
- the advantage of the drum segments is that the balls have a certain spatial limitation in their respective segments. Above all, however, the drum segments have the advantage that the paint does not collect in the lower area due to gravity. Due to the segmentation, the drum is evenly filled with paint.
- the grinding zone can have an additional water supply in order to further dilute the colored dough produced in the dough zone with water.
- This additional water supply can also be used to continuously clean the inlet face of the drum.
- this additional water input can also be dispensed with.
- a further development of the manufacturing device for paint according to the invention proposes that an outlet nozzle of the outlet is rotatably mounted and the required fill level in the mixer can thereby be adjusted.
- a further development suggests that an additional conveyor for the pasted paint powder is arranged between the dough zone and the grinding zone. This has the advantage that the color powder pasted in the dough zone is fed to the grinding zone without the formation of dust, so that the pasted color powder is continuously removed.
- the conveyor preferably consists of fixed and inclined shear blades.
- a shear zone with at least four shear blades is additionally created between the dough zone and the grinding zone.
- the pasted paint powder which is rotating, experiences an axial component as a result of the shear blades, which are inclined with respect to the longitudinal axis of the shaft, which ensures that the pasted paint powder is transported forward.
- the shear blades are preferably evenly distributed around the entire circumference.
- the already mentioned additional water supply can also be located in the area of these shear blades.
- This mixing and transport device can be formed by the continuous shaft, which is equipped with corresponding mixing and transport paddles.
- the device for producing paint whereby dry paint powder is mixed with water, has a dough zone 1, a shear zone 2, a grinding zone 3 and finally an outlet 4.
- a shaft 6 is rotatably mounted in a common mixing and delivery tube 5 and is rotated by a corresponding drive transferred.
- the mixing and delivery pipe 5 has a significantly larger diameter than in the dough zone 1.
- the shaft 6 has mixing and conveying paddles 7 within the mixing and conveying tube 5. Furthermore, the mixing and delivery pipe 5 is equipped with two water feeds 8. The shaft 6 with its mixing and conveying paddles 7 form a mixing and conveying device 9 for the supplied dry paint powder.
- the mixing and delivery pipe 5 has wing-like and inclined shear blades 10 in the area of the inside end wall, which are evenly distributed around the circumference. These shear blades 10 define a conveying device 11 for the colored powder that has been pasted from the dough zone 1 to the subsequent grinding zone 3.
- the grinding zone 3 is formed by a cylindrical drum 12 which is fixed on the shaft 6. 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 formed, for example, by a perforated plate or a sieve. In the interior of the drum 12 there are also radial partition walls 14, which are likewise formed by perforated plates and divide the drum into individual segments 15. These are each filled with balls 16 made of glass, metal, ceramic or another suitable hard material. The diameter of these balls 16 is of course larger than the diameter of the openings in the end walls 13 and in the partition walls 14. Finally, the mixing and delivery pipe 5 in the area of the grinding zone 3 also has two water inlets 17, which, however, do not necessarily have to be present.
- the outlet 4 is formed by a flanged outlet nozzle 18 which is rotatably mounted so that the required fill level in the mixer can be adjusted.
- the outlet 4 is equipped with a hitch for a pump.
- the shaft 6 is provided with mixing and transport paddles 19 which define an additional mixing and transport device 20.
- the color mixer works as follows: The shaft 6 with its mixing and conveying paddles 7, 19 and with its drum 12 is rotated so that the paint mixer is in the operating state.
- the dough zone 1 is supplied with dry color powder, which is indicated schematically by the arrow P. is.
- the dry paint powder is picked up by the mixing and conveying paddles 7 and mixed with the water supplied through the water supply 8 and fed to the shear zone 2.
- the metered amount of color powder is fed with so much water that a dough is formed which is mixed by the mixing and conveying paddles 7.
- This slurry enters the shear zone 2 and is conveyed forward by the fixedly arranged and inclined shear blades 10, so that the slurry passes through the end wall 13 in the form of the perforated plate into the segments 15 of the drum 12. Water can be fed in further via the water feeds 17, so that a slurry is formed.
Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Herstellen von Farbe, wobei trockenes Farbpulver mit Wasser vermischt wird.The invention relates to a device for producing paint, wherein dry paint powder is mixed with water.
Es ist bekannt, flüssige Farbe dadurch herzustellen, daß trockenes Farbpulver mit Wasser vermischt wird. Dies wird derzeit so gemacht, daß man in einen Behälter trockenes Farbpulver zusammen mit Wasser gibt und anschließend so lange miteinander verrührt, bis die flüssige Farbe ihre übliche Konsistenz hat, wobei das Verrühren maschinell mittels eines entsprechenden Rührers erfolgen kann. Allerdings ist von Nachteil, daß die Farbe immer nur in kleinen Mengen hergestellt werden kann. Vor allem aber hat das bekannte Herstellungsverfahren den Nachteil, daß damit eine kontinuierliche Herstellung der flüssigen Farbe nicht möglich ist, da bislang die Farbe immer nur portionsweise angerührt werden kann.It is known to produce liquid paint by mixing dry paint powder with water. This is currently done in such a way that dry paint powder is added to a container together with water and then stirred together until the liquid paint has its usual consistency, which can be done mechanically by means of an appropriate stirrer. However, it is disadvantageous that the paint can only ever be produced in small quantities. Above all, however, the known production process has the disadvantage that it is not possible to produce the liquid paint continuously, since so far the paint can only be mixed in portions.
Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine einfach handhabbare Vorrichtung zum Herstellen von Farbe zu schaffen, mittels der insbesondere auch eine kontinuierliche Farbherstellung möglich ist.Proceeding from this, the object of the invention is to create an easy-to-use device for producing color, by means of which, in particular, continuous color production is also possible.
Die technische Lösung ist gekennzeichnet durch eine Anteigzone mit einer Misch-und Fördereinrichtung für das zugeführte trockene Farbpulver sowie mit einer an der Misch-und Fördereinrichtung angeordneten Wasserzuführung, weiterhin durch eine der Anteigzone nachgeordnete Mahlzone zum Zermahlen des mit dem Wasser versetzten Farbpulvers sowie schließlich durch einen der Mahlzone nachgeordneten Auslauf für die fertige Farbe.The technical solution is characterized by a dough zone with a mixing and conveying device for the supplied dry paint powder and with a water supply arranged on the mixing and conveying device, further by a grinding zone downstream of the dough zone for grinding the paint powder mixed with the water and finally by a the outlet for the finished color after the grinding zone.
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, welcher gleichzeitig während des Mischvorganges der nachgeordneten Mahlzone zugeführt wird, 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. Diese 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 operating paint mixer, by means of which a continuous production of paint is possible, so that the supplied dry paint powder can be applied continuously and without interruption to a facade, for example, after mixing with water. The basic idea of the manufacturing device according to the invention is that the dry color powder to be processed is first fed to the manufacturing device by means of an appropriate device. In a first step, the dry color powder is first mixed with water in the dough zone, so that a type of dough or porridge is formed, which is simultaneously fed to the downstream grinding zone during the mixing process, where the dough or porridge is then ground and thus homogenized in order to in this way to obtain the finished liquid color with the usual conventional consistency. This finished paint can then be discharged through the outlet, for example by pumping off the liquid paint and processing it immediately. According to the invention, it is therefore a multi-stage system, in which a dough or porridge is first produced, which is then evened out by a grinding process.
Vorzugsweise weist die Anteigzone ein Misch- und Förderrohr mit einer darin angeordneten Welle sowie mit der Wasserzuführung auf. Die Welle ist somit 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.The dough zone preferably has a mixing and conveying tube with a shaft arranged therein and with the water supply. The shaft is thus rotatably mounted within the mixing and conveying tube and has corresponding mixing paddles or comparable devices for the mixing process and transport paddles for conveying the dough or slurry, for example in the form of inclined blades. Instead of this transport paddle, it is of course also conceivable to use other transport devices, for example a screw conveyor.
Eine weitere Weiterbildung der erfindungsgemäßen Herstellungsvorrichtung schlägt vor, daß die Wasserzufuhrmenge in Abhängigkeit von der Farbpulverfördermenge steuerbar ist. Das bedeutet, daß dem geförderten Farbpulver immer eine wohldosierte und fest vorgegebene Wassermenge zugeführt wird, so daß die Farbe automatisch den gewünschten Wassergehalt erhält.A further development of the manufacturing device according to the invention proposes that the water supply quantity can be controlled as a function of the color powder delivery quantity. This means that a well-dosed and fixed amount of water is always added to the conveyed paint powder, so that the paint automatically receives the desired water content.
In einer bevorzugten konstruktiven Ausgestaltung der Mahlzone besteht diese aus einer Vielzahl von zueinander bewegten sowie in einer dichten Packung aneinanderliegenden Körpern, durch die hindurch die angeteigte Farbe hindurchleitbar ist. Die Grundidee der so ausgebildeten 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.In a preferred constructive embodiment of the grinding zone, this consists of a plurality of bodies which are moved towards one another and lie in a tight packing against one another, through which the pasted paint can be passed. The basic idea of the grinding device designed in this way is to provide a large number of loose bodies, which are moved against one another in particular by moving a corresponding receptacle. The bodies sliding against one another and rolling on one another 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, so that the liquid color is ultimately produced in a homogeneously uniform consistency. The degree of grinding and mixing naturally depends on the length of the grinding zone and the speed at which the paint passes.
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 another 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 Weiterbildung hiervon schlägt vor, daß die Körper in einer drehbaren, zylinderförmigen Trommel angeordnet sind, wobei die beiden Stirnwände jeweils durch ein Lochblech oder Sieb gebildet sind. Die Grundidee besteht somit darin, eine derartige 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.A further development of this suggests that the bodies are arranged in a rotatable, cylindrical drum, the two end walls each being formed by a perforated plate or sieve. The basic idea is to make such a drum in particular to fill with balls and to set this drum in a rotary motion so that the balls are constantly moved and shifted and thus enable the grinding process. The drum will have a closed cylinder jacket, while the two end faces have openings, one end face serving as an inlet for the pasted paint and the other end face serving as an outlet for the finished liquid paint. The perforated plates or screens for the end walls have corresponding openings, the diameter of which is of course smaller than the diameter of the balls.
Eine bevorzugte konstruktive Ausbildung der Trommel schlägt vor, daß sie innerhalb des Misch- und Förderrohres auf der Welle fest angeordnet ist. 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.A preferred constructive design of the drum suggests that it is fixedly arranged on the shaft within the mixing and delivery pipe. This means that when the shaft in the dough zone rotates and the color paste or pulp is formed, the drum in the grinding zone rotates simultaneously and synchronously. The advantage lies in the fact that the shaft forms a structural unit together with the drum, just like the mixing and conveying pipe, which is not only located in the dough zone, but also in the grinding zone, where, however, in comparison to the dough zone for receiving the Drum has a significantly larger diameter.
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 consisting of a perforated plate or sieve. The drum thus has radial partition walls with respect to the central axis, which divide the drum into individual chambers, in each of which there is a ball packing. The partitions can be provided with openings which allow the paint to pass through, but not through the balls. The advantage of the drum segments is that the balls have a certain spatial limitation in their respective segments. Above all, however, the drum segments have the advantage that the paint does not collect in the lower area due to gravity. Due to the segmentation, the drum is evenly filled 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 in order to further dilute the colored dough produced in the dough zone with water. This additional water supply can also be used to continuously clean the inlet face of the drum. Of course, this additional water input can also 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.A further development of the manufacturing device for paint according to the invention proposes that an outlet nozzle of the outlet is rotatably mounted and the required fill level in the mixer can thereby be adjusted.
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.A further development suggests that an additional conveyor for the pasted paint powder is arranged between the dough zone and the grinding zone. This has the advantage that the color powder pasted in the dough zone is fed to the grinding zone without the formation of dust, so that the pasted color powder is continuously removed.
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 shear blades. As a result, a shear zone with at least four shear blades is additionally created between the dough zone and the grinding zone. The pasted paint powder, which is rotating, experiences an axial component as a result of the shear blades, which are inclined with respect to the longitudinal axis of the shaft, which ensures that the pasted paint powder is transported forward. In order to achieve even transport, the shear blades are preferably evenly distributed around the entire circumference. The already mentioned additional water supply can also be located in the area of these shear blades.
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 an additional mixing and transport device is provided between the grinding zone and the outlet. This mixing and transport device can be formed by the continuous shaft, which is equipped with corresponding mixing and transport paddles.

Die Vorrichtung zum Herstellen von Farbe, wobei trockenes Farbpulver mit Wasser vermischt wird, weist hintereinander eine Anteigzone 1, eine Scherzone 2, eine Mahlzone 3 sowie schließlich einen Auslauf 4 auf. Dabei ist in einem gemeinsamen Misch- und Förderrohr 5 eine Welle 6 drehbar gelagert und wird durch einen entsprechenden Antrieb in Drehbewegung versetzt. Im Bereich der Scherzone 2 sowie Mahlzone 3 weist das Misch- und Förderrohr 5 einen deutlich größeren Durchmesser auf als in der Anteigzone 1.The device for producing paint, whereby dry paint powder is mixed with water, has a
In der Anteigzone 1 weist die Welle 6 innerhalb des Misch- und Förderrohres 5 Misch-und Förderpaddel 7 auf. Weiterhin ist das Misch- und Förderrohr 5 mit zwei Wasserzuführungen 8 ausgestattet.

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
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
Der Auslauf 4 ist durch einen angeflanschten Auslaufstutzen 18 gebildet, welcher drehbar gelagert ist, so daß der erforderliche Füllstand im Mischer angepaßt werden kann. Darüber hinaus ist der Auslauf 4 mit einer Anhängevorrichtung für eine Pumpe ausgestattet.The
Innerhalb des Auslaufstutzens 18 ist die Welle 6 mit Misch- und Transportpaddeln 19 versehen, welche eine zusätzliche Misch- und Transporteinrichtung 20 definieren.Within the
Der Farbmischer funktioniert wie folgt:
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 color mixer works as follows:

Über die Wasserzuführungen 17 kann dabei weiter Wasser zugeführt werden, so daß ein Brei entsteht.This slurry enters the
