Description

Vorrichtung zum Herstellen eines Mehrkomponentengemisches und Verfahren zum Betreiben einer derartigen Vorrichtung Device for producing a multicomponent mixture and method for operating such a device
Die Erfindung betrifft eine Vorrichtung zum Herstellen eines Mehrkomponentengemisches mit einer Mischkammer und einer Mischvorrichtung, wobei die Mischvorrichtung einen in der Mischkammer angeordneten, um eine Drehachse drehbar angetriebenen Rührer aufweist. Sie betrifft weiter ein Verfahren zum Betreiben einer derartigen Vorrichtung. The invention relates to a device for producing a multicomponent mixture with a mixing chamber and a mixing device, the mixing device having a stirrer arranged in the mixing chamber and rotatably driven about an axis of rotation. It also relates to a method for operating such a device.
Aus der DE 10 2012 103 885 A1 ist eine Vorrichtung zum Herstellen eines From DE 10 2012 103 885 A1 a device for producing a
Mehrkomponentengemisches bekannt, bei der die Mischkammer mittels in die Kammerwandung eingelassener Wasserkanäle spülbar und zudem temperierbar ist. Multi-component mixture is known in which the mixing chamber can be rinsed by means of water channels let into the chamber wall and can also be tempered.
Derartige Mischvorrichtungen dienen dazu, mehrere Komponenten eines Kunststoffgemisches unmittelbar vor dem Gebrauch miteinander zu vermischen und für die Verarbeitung zur Verfügung zu stellen. Beispielsweise kann die Mischkammer einen Auslass aufweisen, durch den ein Strang des fertigen Gemisches ausgegeben und beispielsweise mittels eines Roboterarms auf eine Oberfläche aufgebracht werden kann. Mixing devices of this type serve to mix several components of a plastic mixture with one another immediately before use and to make them available for processing. For example, the mixing chamber can have an outlet through which a strand of the finished mixture can be dispensed and applied to a surface, for example by means of a robot arm.
Problematisch ist dabei, dass der Rührer bei langen Wartezeiten zwischen einzelnen Dosierungen stark verschmutzt und nur schwer zu reinigen ist, weil die zu vermischenden Komponenten bereits in der Mischkammer miteinander reagieren. The problem here is that if there are long waiting times between individual doses, the stirrer is very dirty and difficult to clean because the components to be mixed react with one another in the mixing chamber.
Daher besteht die Aufgabe der Erfindung darin, eine Vorrichtung zum Herstellen eines Therefore, the object of the invention is to provide an apparatus for producing a
Mehrkomponentengemisches anzugeben, bei der die Verschmutzung des Rührers zumindest stark reduziert ist. Ferner soll ein Verfahren zum Betreiben einer derartigen Vorrichtung angegeben werden. Specify a multi-component mixture in which the stirrer contamination is at least greatly reduced. Furthermore, a method for operating such a device is to be specified.
Diese Aufgabe wird gelöst mit dem Gegenstand der Patentansprüche 1 und 9. Weitere This object is achieved with the subject matter of claims 1 and 9. Further
Ausführungsformen und vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche. Embodiments and advantageous configurations are the subject of the subclaims.
Gemäß einem Aspekt der Erfindung wird eine Vorrichtung zum Herstellen eines According to one aspect of the invention, an apparatus for producing a
Mehrkomponentengemisches mit einer Mischkammer und einer Mischvorrichtung angegeben, wobei die Mischvorrichtung einen in der Mischkammer angeordneten, um eine Drehachse drehbar angetriebenen Rührer aufweist, wobei im Innern des Rührers ein von einem Temperiermedium durchströmbares Temperierkanalsystem zur Temperierung des Rührers angeordnet ist. Multi-component mixture specified with a mixing chamber and a mixing device, the mixing device having a stirrer arranged in the mixing chamber, rotatably driven about an axis of rotation, a temperature control channel system through which a temperature control medium can flow for controlling the temperature of the stirrer is arranged inside the stirrer.
Dabei ist es einerseits denkbar, das Temperierkanalsystem als Heizkanalsystem auszugestalten, welches von einem Heizmedium als Temperiermedium durchströmbar ist und zur Beheizung des Rührers vorgesehen ist. Damit können beispielsweise Reaktionen der Komponenten beeinflusst werden und insbesondere beschleunigt werden. Alternativ dazu ist eine Gestaltung des Temperierkanalsystem als Kühlkanalsystem denkbar, welches von einem Kühlmedium als Temperiermedium durchströmbar ist und zur Kühlung des Rührers vorgesehen ist. Eine solche Vorrichtung weist den Vorteil auf, dass eine Reaktion der Komponenten miteinander zumindest an der Oberfläche des Rührers verlangsamt werden kann, wenn dieser eine verhältnismäßig niedrige Temperatur aufweist. Die Reaktion in der Mischkammer erfolgt im Wesentlichen nach der van-’t- Hoff sehen Regel. Wie sich herausgestellt hat, lässt sich mit einer Reduktion der Temperatur um 10°C eine lokale Erhöhung der Topfzeit um einen Faktor 2 bis 3 erreichen. Verschmutzungen des Rührers können somit reduziert werden. On the one hand, it is conceivable to design the temperature control channel system as a heating channel system through which a heating medium can flow as a temperature control medium and is provided for heating the stirrer. In this way, for example, reactions of the components can be influenced and, in particular, accelerated. Alternatively, the The temperature control channel system is conceivable as a cooling channel system through which a cooling medium can flow as the temperature control medium and is provided for cooling the stirrer. Such a device has the advantage that a reaction of the components with one another can be slowed down at least on the surface of the stirrer when the stirrer is at a relatively low temperature. The reaction in the mixing chamber essentially takes place according to the van-'t-Hoff rule. It has been found that reducing the temperature by 10 ° C increases the pot life locally by a factor of 2 to 3. Dirt on the stirrer can thus be reduced.
Gemäß einer Ausführungsform der Erfindung ist der Rührer auf einer Welle angeordnet, die im Bereich ihres ersten Endes mit dem Rührer verbunden ist und im Bereich ihres zweiten Endes drehbar angetrieben ist. Bei einer derartigen Anordnung kann es auch vorgesehen sein, den Rührer innerhalb der Mischkammer axial bewegbar auszubilden, so dass er in Richtung der Drehachse abgesenkt und angehoben werden kann, um einen am Boden der Mischkammer angeordneten Auslass zu verschließen oder freizugeben. Auf diese Weise kann ein fertig zubereitetes Mehrkomponentengemisch nach dem Mischvorgang für die weitere Verwendung ausgegeben werden. According to one embodiment of the invention, the stirrer is arranged on a shaft which is connected to the stirrer in the area of its first end and is rotatably driven in the area of its second end. With such an arrangement it can also be provided that the stirrer is designed to be axially movable within the mixing chamber so that it can be lowered and raised in the direction of the axis of rotation in order to close or open an outlet arranged at the bottom of the mixing chamber. In this way, a fully prepared multi-component mixture can be dispensed for further use after the mixing process.
Beim Einsatz eines Rührers ist dessen Drehzahl vorzugsweise einstellbar. Besonders bevorzugt lässt sich die Drehzahl des Rührers auf einen Wert zwischen 1 U/min und 6000 U/min einstellen. Ganz besonders bevorzugt auf einen Wert zwischen 800 U/min und 3000 U/min. When using a stirrer, its speed is preferably adjustable. The speed of the stirrer can particularly preferably be set to a value between 1 rpm and 6000 rpm. Very particularly preferably to a value between 800 rpm and 3000 rpm.
Der Druck in der Mischkammer liegt vorzugsweise in einem Bereich zwischen 0,5 bar und 4,0 bar, vorzugsweise in einem Bereich zwischen 1 ,5 bar und 3,0 bar. Es können aber auch Anwendungen in Betracht kommen, bei denen ein Druck in der Mischkammer von bis zu 50bar herrschen, so dass die Mischkammer vorzugsweise derart ausgelegt und gestaltet ist, einem Innendruck standzuhalten, welcher einen Wert aufweist, der in einem Bereich zwischen 0,5 bar und 50 bar liegt. The pressure in the mixing chamber is preferably in a range between 0.5 bar and 4.0 bar, preferably in a range between 1.5 bar and 3.0 bar. However, applications can also come into consideration in which the pressure in the mixing chamber is up to 50 bar, so that the mixing chamber is preferably designed and configured to withstand an internal pressure which has a value in a range between 0.5 bar and 50 bar.
Gemäß einer Ausführungsform ist das Temperierkanalsystem in Hohlräumen des Rührers angeordnet und Wände der Hohlräume bilden Wände des Temperierkanalsystems. According to one embodiment, the temperature control channel system is arranged in cavities of the stirrer and walls of the cavities form walls of the temperature control channel system.
Diese Anordnung, bei der insbesondere ein axial verlaufender Hohlraum als Temperierkanal vorgesehen sein kann, hat den Vorteil, dass die Temperierung besonders effizient ist, da das Temperiermedium unmittelbar in Kontakt mit dem Rührer steht. This arrangement, in which, in particular, an axially extending cavity can be provided as the temperature control channel, has the advantage that the temperature control is particularly efficient, since the temperature control medium is in direct contact with the stirrer.
Um einen effizienten Temperierkreislauf zu schaffen, kann es bei dieser Ausführungsform vorgesehen sein, dass die Welle ein Temperierkanalsystem aufweist, das mit dem Temperierkanalsystem des Rührers in Fluidverbindung steht, wobei im Bereich des zweiten Endes der Welle ein Zulauf und ein Ablauf für das Temperiermedium vorgesehen sind. In order to create an efficient temperature control circuit, it can be provided in this embodiment that the shaft has a temperature control channel system that is connected to the The temperature control channel system of the stirrer is in fluid connection, an inlet and an outlet for the temperature control medium being provided in the region of the second end of the shaft.
Bei dieser Ausführungsform sind der Zulauf und der Ablauf demnach außerhalb der Mischkammer im Bereich des zweiten Endes der Welle vorgesehen, wobei beispielsweise der Zulauf und der Ablauf in mit dem Temperiermedium gefüllten Kammern angeordnet sind, in denen ein In this embodiment, the inlet and the outlet are accordingly provided outside the mixing chamber in the region of the second end of the shaft, for example the inlet and the outlet are arranged in chambers filled with the temperature control medium, in which a
unterschiedlicher Druck herrscht, so dass das Temperierkanalsystem von dem Zulauf zum Ablauf durchströmt wird. Die Strömung kann dadurch geleitet werden, dass innerhalb des zumindest einen Temperierkanals ein Rohr angeordnet ist, das mit dem Auslass in Verbindung steht. different pressure prevails, so that the temperature control channel system flows through from the inlet to the outlet. The flow can be directed in that a tube is arranged within the at least one temperature control channel and is connected to the outlet.
Während beispielsweise ein Ende des Rohres mit dem Auslass im Bereich des zweiten Endes der Welle in Verbindung steht, kann ein zweites Ende des Rohrs in dem Temperierkanalsystem des Rührers und insbesondere in einem distalen Bereich des Temperierkanalsystems angeordnet sein, sodass das Temperiermedium in dem Temperierkanalsystem außerhalb des Rohres hin- und innerhalb des Rohres zurückströmt. For example, while one end of the tube is connected to the outlet in the area of the second end of the shaft, a second end of the tube can be arranged in the temperature control channel system of the stirrer and in particular in a distal area of the temperature control channel system, so that the temperature control medium in the temperature control channel system is outside the Pipe flows back and forth within the pipe.
Gemäß einer alternativen Ausführungsform ist das Temperierkanalsystem in einer Temperierlanze ausgebildet, die in einem Hohlraum des Rührers angeordnet ist. According to an alternative embodiment, the temperature control channel system is formed in a temperature control lance which is arranged in a cavity of the stirrer.

Die Vorrichtung 1 zum Herstellen eines Mehrkomponentengemisches gemäß Figur 1 weist eine Mischkammer 2 sowie eine Mischvorrichtung 3 auf. Die Mischvorrichtung 3 umfasst einen in der Mischkammer 2 angeordneten Rührer 4, der von einer Welle 12 um eine Längsachse L drehbar angetrieben wird. Der Rührer 4 hat die Aufgabe, verschiedene Komponenten eines The device 1 for producing a multicomponent mixture according to FIG. 1 has a mixing chamber 2 and a mixing device 3. The mixing device 3 comprises one in Mixing chamber 2 arranged stirrer 4, which is rotatably driven about a longitudinal axis L by a shaft 12. The stirrer 4 has the task of various components of a
Mehrkomponentengemisches, die durch nicht gezeigte Leitungen in die Mischkammer 2 eingebracht werden, aktiv miteinander zu vermischen. Bei dem Mehrkomponentengemisch handelt es sich insbesondere um einen Kunststoff. To actively mix multicomponent mixtures, which are introduced into the mixing chamber 2 through lines not shown, with one another. The multi-component mixture is in particular a plastic.
Das fertig zubereitete Mehrkomponentengemisch kann durch einen Auslass 15 aus der The ready-made multi-component mixture can through an outlet 15 from the
Mischkammer entnommen werden, wobei der Auslass 15 durch den Rührer 4, der in axialer Richtung bewegbar ist, verschlossen und freigegeben wird. Mixing chamber can be removed, the outlet 15 being closed and released by the stirrer 4, which is movable in the axial direction.
Der Rührer 4 weist ein erstes Ende 10 auf, mittels dessen der Auslass 15 verschlossen werden kann. Ferner weist er ein zweites Ende 1 1 auf, das mit einem ersten Ende 13 der Welle 12 verbunden ist. Ein zweites Ende 14 der Welle 12 weist einen nicht gezeigten Antrieb auf. The stirrer 4 has a first end 10, by means of which the outlet 15 can be closed. It also has a second end 11, which is connected to a first end 13 of the shaft 12. A second end 14 of the shaft 12 has a drive (not shown).
Um Verschmutzungen des Rührers 4 durch Vernetzen des Materials in der Mischkammer 2 gering zu halten, wird der Rührer 4 von innen gekühlt. Die Wände der Mischkammer 2 können ebenfalls mit Kühlkanälen ausgestattet sein, die eine Kühlung der Mischkammer 2 ermöglichen. In order to keep the stirrer 4 soiled by crosslinking the material in the mixing chamber 2, the stirrer 4 is cooled from the inside. The walls of the mixing chamber 2 can also be equipped with cooling channels that enable the mixing chamber 2 to be cooled.
Der Rührer 4 weist zur Kühlung einen Hohlraum 23 auf, der durch Wände 9 begrenzt wird und der sich von dem zweiten Ende 1 1 des Rührers 4 fast an dessen erstes Ende 10 erstreckt. In dem Hohlraum 23 ist ein Kühlkanalsystem 5 als Temperierkanalsystem ausgebildet, wobei bei der in Figur 1 gezeigten Ausführungsform die Wände 9 des Hohlraums auch Wände des For cooling, the stirrer 4 has a cavity 23 which is delimited by walls 9 and which extends from the second end 11 of the stirrer 4 almost to its first end 10. In the cavity 23, a cooling channel system 5 is designed as a temperature control channel system, wherein in the embodiment shown in Figure 1, the walls 9 of the cavity also walls of the
Kühlkanalsystems 5 bilden. Das Kühlkanalsystem 5 ist somit durch die Wände 9 des Hohlraums 23 sowie zusätzlich durch ein Rohr 8 gebildet, das koaxial in dem Hohlraum 23 angeordnet ist. Form cooling channel system 5. The cooling channel system 5 is thus formed by the walls 9 of the cavity 23 and additionally by a tube 8 which is arranged coaxially in the cavity 23.
Alternativ zu der hier dargestellten Variante ist selbstverständlich auch eine Einrichtung eines Heizkanalsystems als Temperierkanalsystem denkbar, welches den Rührer von innen beheizt. Dieses kann hinsichtlich des dargestellten Kühlkanalsystems 5 vergleichbare Merkmale aufweisen, wobei hier eine Durchströmung eines Heizmediums zweckmäßig ist. As an alternative to the variant shown here, it is of course also conceivable to set up a heating channel system as a temperature control channel system which heats the stirrer from the inside. This can have comparable features with regard to the cooling channel system 5 shown, a flow of a heating medium being expedient here.
Auf diese Weise ist in dem Hohlraum 23 sowohl ein Vorlauf 6 gebildet, der mit einem Zulauf 16 im Bereich des zweiten Endes 14 der Welle 12 in Verbindung steht, als auch ein Rücklauf 7, der mit einem Ablauf 17 im Bereich des zweiten Endes 14 der Welle 12 in Verbindung steht. Das auf diese Weise gebildete Kühlkanalsystem 5 wird, wie durch die Pfeile 25 angedeutet, von einem als Kühlmedium zum Einsatz kommenden Temperiermedium, beispielsweise Wasser, durchströmt. Das Kühlmedium strömt durch den Zulauf 16 in einen innerhalb der Welle 12 verlaufenden Hohlraum 27 ein und fließt von dort in den Hohlraum 23 des Rührers 4, der mit dem Hohlraum 27 in Fluidverbindung steht. Dabei strömt das Kühlmedium zwischen dem Rohr 8 und den Wänden 9 des Hohlraums 27, 23 bis in den Bereich des ersten Endes 10 des Rührers 4, wo es in das Rohr 8 einströmt, von dort in das Rohr 28 innerhalb der Welle 12 und von dort zu dem Ablauf 17 strömt. Im Bereich des Vorlaufs 6 nimmt das Kühlmedium dabei Wärme aus dem Material des Rührers 4 auf und kühlt dadurch dessen Oberfläche 29. Im Rücklauf 7 wird erwärmtes Kühlmedium abtransportiert. In this way, both a flow 6 is formed in the cavity 23, which is connected to an inlet 16 in the region of the second end 14 of the shaft 12, and a return 7, which is connected to an outlet 17 in the region of the second end 14 of the Shaft 12 is in communication. The cooling channel system 5 formed in this way, as indicated by the arrows 25, is flowed through by a temperature control medium, for example water, which is used as the cooling medium. The cooling medium flows through the inlet 16 into a cavity 27 running inside the shaft 12 and flows from there into the cavity 23 of the stirrer 4, which is in fluid connection with the cavity 27. The cooling medium flows between the tube 8 and the walls 9 of the cavity 27, 23 to the area of the first end 10 of the stirrer 4, where it flows into the tube 8, from there into the tube 28 within the shaft 12 and from there flows to the outlet 17. In the area of the flow 6, the cooling medium absorbs heat from the material of the stirrer 4 and thereby cools its surface 29. In the return 7, heated cooling medium is transported away.
Figur 2 zeigt eine zweite Ausführungsform der Vorrichtung 1 , die sich von der in Figur 1 gezeigten dadurch unterscheidet, dass in dem Hohlraum 23, 27 eine als Kühllanze 18 gestaltete FIG. 2 shows a second embodiment of the device 1, which differs from that shown in FIG. 1 in that a cooling lance 18 designed as a cooling lance in the cavity 23, 27
Termperierlanze angeordnet ist. Diese erstreckt sich von dem Bereich des ersten Endes 10 des Rührers 4 bis zum Bereich des zweiten Endes 14 der Welle 12. Die Kühllanze 18 weist in ihrem Inneren ebenfalls ein Rohr 19 auf, wobei ein Vorlauf 6 des Kühlkanalsystems 5 außerhalb des Rohres 19 und ein Rücklauf 7 innerhalb des Rohres 19 gebildet ist. Im Bereich des zweiten Endes 14 der Welle 12 weist die Kühllanze 18 Öffnungen eines Zulaufs 20 sowie eines Ablaufs 21 auf. Termperierlanze is arranged. This extends from the area of the first end 10 of the stirrer 4 to the area of the second end 14 of the shaft 12. The cooling lance 18 also has a tube 19 in its interior, with a flow 6 of the cooling channel system 5 outside the tube 19 and a Return 7 is formed within the tube 19. In the area of the second end 14 of the shaft 12, the cooling lance 18 has openings of an inlet 20 and an outlet 21.
Die Kühllanze 18 kann beispielsweise in den Rührer 4 und oder die Welle 12 eingesteckt oder eingeschraubt sein. Bei einem Austausch des Rührers 4 kann die Kühllanze 18 mit der Welle 12 verbunden bleiben. The cooling lance 18 can for example be inserted or screwed into the stirrer 4 and / or the shaft 12. When the stirrer 4 is replaced, the cooling lance 18 can remain connected to the shaft 12.
Um einen besonders guten Wärmeübergang und somit eine besonders gute Kühlleistung zu erzielen, ist ein Spalt zwischen den Außenwänden der Kühllanze 18 und den den Hohlraum 23 begrenzenden Wänden 9 möglichst klein ausgebildet. In order to achieve particularly good heat transfer and thus particularly good cooling performance, a gap between the outer walls of the cooling lance 18 and the walls 9 delimiting the cavity 23 is designed to be as small as possible.
Figur 3 zeigt eine dritte Ausführungsform der Vorrichtung 1 , die sich von den in Figur 1 und 2 gezeigten Ausführungsformen dadurch unterscheidet, dass das Kühlkanalsystem 5 mittels eines Wärmerohrs 22 ausgebildet ist, das in dem Hohlraum 23, 27 angeordnet ist und sich von dem Bereich des ersten Endes 10 des Rührers 4 bis in den Bereich des zweiten Endes 14 der Welle 12 erstreckt. Ein distales Ende 26 des Wärmerohrs 22 kann dabei eine aktive Kühlung 24 aufweisen. Figure 3 shows a third embodiment of the device 1, which differs from the embodiments shown in Figures 1 and 2 in that the cooling channel system 5 is formed by means of a heat pipe 22, which is arranged in the cavity 23, 27 and extends from the area of the first end 10 of the stirrer 4 extends into the region of the second end 14 of the shaft 12. A distal end 26 of the heat pipe 22 can have an active cooling 24.
Das Wärmerohr 22 ist in der gezeigten Ausführungsform lediglich schematisch gezeigt. Es handelt sich dabei um ein dem Fachmann bekanntes Wärmetransportmittel, bei dem im Betrieb ein in dem Wärmerohr 22 vorgehaltenes Arbeitsmedium im Bereich des Rührers 4 verdampft und in eine im Bereich des distalen Endes 26 angeordnete Kühlzone strömt, wo es Wärme abgibt und wieder kondensiert. Dabei bildet das Wärmerohr 22 ein geschlossenes System aus, das besonders einfach in den Rührer 4 und die Welle 12 zu integrieren ist. The heat pipe 22 is shown only schematically in the embodiment shown. This is a heat transport medium known to those skilled in the art, in which, during operation, a working medium stored in the heat pipe 22 evaporates in the area of the stirrer 4 and flows into a cooling zone located in the area of the distal end 26, where it gives off heat and condenses again. The heat pipe 22 forms a closed system which can be integrated particularly easily into the stirrer 4 and the shaft 12.
Das Wärmerohr 22 kann ebenso wie die Kühllanze 18 gemäß Figur 2 in den Rührer 4 bzw. die Welle 12 eingeschraubt oder eingesteckt sein und bei einem Austausch des Rührers 4 mit der Welle 12 verbunden bleiben. Ein Spalt zwischen den Außenwänden des Wärmerohrs 22 und den den Hohlraum 23 begrenzenden Wänden 9 wird für eine effiziente Kühlung möglichst klein ausgebildet. Bezugszeichenliste The heat pipe 22, like the cooling lance 18 according to FIG. 2, can be screwed or plugged into the stirrer 4 or the shaft 12 and remain connected to the shaft 12 when the stirrer 4 is replaced. A gap between the outer walls of the heat pipe 22 and the walls 9 delimiting the cavity 23 is designed to be as small as possible for efficient cooling. List of reference symbols
