Definitions

  • the present invention relates to a pumping and mixing device for powdered or free-flowing media and a system for providing pasty media for construction purposes.
  • document EP-A-0 147 631 discloses a pumping and mixing device having the features of the preamble of claim 1.
  • Document DE-A-196 17 423 discloses a pumping and mixing device including a cantilevered conveyor shaft.
  • the conveyor shaft is adapted to be inserted or introduced into the storage container, thus promoting powdered or free-flowing medium as continuously as possible from this closed container out. This then optionally passes into a flow chamber, whereby a certain homogenization of the delivery process can be achieved.
  • the deflecting from the pumping and mixing device according to the invention free end of the conveyor shaft is designed to crimp into the storage container.
  • a common drive for the mixing and conveying shaft mounted at the opposite end of the mixing chamber effects the drive. This is advantageous over "on both sides suspended" conveyor shafts, which are difficult to fix in the storage container (especially if it is a disposable container) or where the conveyor shaft must necessarily be part of the container.
  • a projecting end of the conveyor shaft Taken individually, they are inserted into a storage container such as a disposable container or the like, the corresponding drive being made from the "back" of the device.
  • the housing of the pumping and mixing device has a flow chamber, wherein this flow chamber downstream of the metering chamber is arranged and the metering chamber is compared to the flow chamber at least partially reduced in cross-section.
  • this flow chamber is not absolutely necessary, especially if other characteristics are given for it.
  • a separate flow chamber is not necessary. This is because a corresponding cross-sectional widening is already given in the storage container itself. It is then spoken of a "flow area", which replaces the flow chamber. From the flow area, which is housed in the storage container, there is naturally a cross-sectional reduction to the interior of the dosing out.
  • the metering chamber at the end facing away from the mixing chamber projects beyond the flange of the pumping and mixing device to the storage container. In other words, it projects beyond, for example, the screw thread or the quick-action closure, so that it is ensured that the foremost end of the metering chamber likewise extends or projects into the storage container itself, so as to achieve a flow area according to the invention.
  • a metering chamber Downstream of the flow area or the flow chamber is then a metering chamber, which at least partially reduced cross-section is compared to the flow chamber or the flow area. It has been shown that a further equalization of the promotion is achieved by this intermediate chamber.
  • a mixing chamber Downstream of the metering chamber is then given a mixing chamber, which is open cross-sectionally reduced towards the metering chamber.
  • the conveyor shaft which extends into or through the metering chamber, is connected to transmit power to a mixing shaft.
  • This mixing shaft ensures in the mixing chamber that from a water connection, which opens into the mixing chamber, water is provided for mixing the powdered or free-flowing medium with water to a pasty mass.
  • a connection for conveying the pasty mass is finally given, so that the mass pressure can be further promoted to higher floors of a building and thus can be brought directly to the processor out.
  • This pumping and mixing device is particularly interesting in connection with a disposable container for providing powdered and free-flowing media, as this example in the DE 20 2004 010 486 the same applicant is disclosed.
  • a disposable container for providing powdered and free-flowing media, as this example in the DE 20 2004 010 486 the same applicant is disclosed.
  • a container is preferably constructed of materials such as corrugated cardboard and thus has a very low weight.
  • the container is in this case designed in particular for receiving the conveyor shaft, so that here results in a continuous flow of powder and a good emptying.
  • other disposable containers going back to the applicant for example, after DE 103 14 146 A1 , of the DE 202 13 063 U1 or the EP 03 09 0261 A1 come into use.
  • the pumping and mixing device provides that the front part of the housing is substantially pressure-tight to the storage container / the disposable container by means of a screw thread, a quick release or the like connected. This results in a standardized connection point, the provision of powdered material is continuously given by this secure connection.
  • the conveyor shaft is designed as a screw conveyor.
  • the conveyor shaft can also be designed as a spiral.
  • This spiral shape is extremely advantageous for loosening up the powdery and free-flowing material in the container. Since the spiral engages relatively far down in the storage container / disposable container, the pressure by the material itself is very high, it usually comes to compression due to self-weight compaction. Here is ensured by the spiral, that it comes here to a loosening, by the given in the one-way container slope (s., Applicant's applications referred to in the introduction), it comes to a assisted by the spiral lead out of the powdery material from the disposable container.
  • This spiral can be made in various ways.
  • additional baffles for powdery material may be present, which may also cause (not necessarily desired) stiffening of the spiral.
  • Also advantageous is a decreasing spiral distance of the spiral in the direction of the storage container, which also reduces the risk of blockages.
  • the free end of the conveyor shaft (preferably when this is designed as a spiral) is cantilevered in the storage container. This results in a "self-centering" of the screw, even if this has a certain bending elasticity, a very good function is given.
  • a further advantageous embodiment provides that the flow chamber has a control and metering window. This makes it possible to check the powder flow at any time during operation.
  • a further advantageous embodiment provides that the region-wise reduction in cross-section of the metering chamber is designed as a partition wall separating the flow chamber, in whose center the conveyor shaft is freely rotatable.
  • the conveyor shaft thus passes through the inlet chamber and the adjoining metering chamber, the intervening (belonging to the metering chamber) bulkhead in this case causes a homogenization the promotion, in the central region of the dosing a passage is provided in which the conveyor shaft / spiral is freely rotatable.
  • the ratio of the narrowest cross-sectional area in the metering chamber (that is, for example, the narrowest cross section of the abovementioned bulkhead) of the largest cross-sectional area in the flow chamber is between 0.01 and 0.5.
  • a further advantageous embodiment provides that in the region of the end of the metering chamber, a gap for the passage of medium from the metering chamber is provided in the mixing chamber.
  • a gap for the passage of medium from the metering chamber is provided in the mixing chamber. This can be carried out in various ways, it is crucial that here an attachment of the conveyor shaft is made possible to the subsequent mixing shaft and at the same time a continuous flow of powder through this gap space.
  • the gap is designed, for example, as a drum with axial recesses, which is supported on a side facing away from the flow chamber of the metering chamber and preferably protrudes into the mixing chamber.
  • the ratio of length of the flow chamber to the length of the metering chamber is between 1 and 2.
  • the ratio of the length of the flow chamber to the length of the mixing chamber is preferably between 0.3 and 0.7.
  • a further advantageous embodiment provides that in the end region of the conveyor shaft, which is repelled by the feed chamber, there is a driver connection to the mixing shaft.
  • a driver connection is also possible within the conveyor shaft, in particular in the region of the flow chamber.
  • a mixing shaft is preferably provided centrally, which has radial arms. These can be designed as a radially outwardly aspirant to the mixture of medium (ie powder and water) or as a spiral boom for conveying medium from the storage container on the one hand. Due to the corresponding adaptation of mixing and delivery jibs, a tuning according to the desired conditions (granulation of the powder, of which pasty medium, etc.) is possible. A corresponding adjustment by replacing the mixing shaft is also possible.
  • a particularly advantageous embodiment provides that at the end of the mixing chamber, on the side facing away from the flow chamber of the device, a common drive for mixing and conveying shaft is mounted.
  • a common drive for mixing and conveying shaft is mounted at the end of the mixing chamber, on the side facing away from the flow chamber of the device.
  • the arrangement of the drive on the conveyor shaft repellent side also offers the advantage that a self-centering of the conveyor shaft (especially if this is designed as a spiral) is easily possible.
  • Another advantage is that at this point a drive is easy to install, this case no fixed mounted drive must be provided, it can also be common on the construction existing drives (even drills) can be connected.
  • a further advantageous embodiment provides that at the output for connecting a conveyor for conveying pasty masses a pumping device, for example according to the EP 1 445 490 A1 the same applicant is possible. This makes it possible that the freshly mixed pasty medium over 30 m, for example, can reach the worker.
  • the modular design also offers the advantage here that the pumping device can alternatively also be connected directly to the disposable container, which already contains pre-mixed pasty medium.
  • the pumping and mixing device has a housing which is divisible into at least two longitudinal sections. This makes it possible, for example, a "metering unit” (consisting of a housing part, which contains the metering chamber and flow chamber) and a “mixing unit” (which contains the mixing chamber) to separate. These longitudinal sections can also be quickly connected to each other again, for example by a clamping device in the form of a quick-release device or a bolt-tensioned clamping device.
  • the inventive system for providing pasty media for construction purposes comprising a pumping and mixing device according to the invention and a correspondingly matched disposable container or a storage container, which or has a connection for introducing the conveyor shaft, also has advantageous developments.
  • the container shape of the pumping and mixing device according to the invention in particular in the region of the conveying shaft or the connecting flange of the pumping and mixing device, follows the disposable container or the storage container. It is particularly advantageous here that the disposable container has a collecting channel in alignment with the conveying shaft.
  • This collecting channel may be made of an extra plastic material, for example, be designed as a plastic injection molded part, or even consist of plain cardboard or optionally be plastic coated or be provided with an applied inliner.
  • the shape of the channel can be conical or flat, both are possible in coordination with the conveyor shaft according to the invention. It is only important that within the container a slope (pyramidal in polygonal cross-sections, essentially conical in circular cross-sections of the container) is given. It is particularly advantageous that the corresponding channel extends to full width or full diameter of the container.
  • the width of the gutter has to be relatively small.
  • the ratio of the largest width of the channel to the largest diameter of the conveyor shaft (within the one-way container) is normally between 0.8 and 2.5, preferably between 0.9 and 1.5.
  • Fig. 1a shows a disposable container as a storage container for connection to a pumping and mixing device according to the invention.
  • the container has, for example, an octagonal cross-section, but other polygonal cross-sections or round cross-sections are also possible.

  • Fig. 1c shows a section perpendicular through the Euro-pallet, in the vertical axis direction of the disposable container.
  • the container has an inner funnel, which opens into a channel, which occupies substantially the full width of the disposable container. At the end of this channel the connection 16 is given. That in the container stored powdery medium is pressed by the weight itself in the direction of the gutter, which can certainly lead to compaction in the gutter.
  • the channel itself may have different cross-sectional shapes, for example, the substantially semicircular cross-sectional shape 20a or the flat or planar cross-sectional shape 20b.
  • a pioneer of the disposable container is that it can be made of a disposable material such as cardboard and therefore is correspondingly lightweight.
  • the construction of the disposable container is possible in various ways, for example by prefabricated plastic parts or by support structures, which may be made of coated cardboard or (if necessary) may be coated with an inliner.
  • the disposable container is on the DE 20 2004 010 486 , of the DE 103 14 146 A1 , of the DE 202 13 063 U1 or the EP 03 09 0261 A1 directed.
  • FIGS. 2a and 2 B show different sections through the pumping and mixing device according to the invention.
  • the disposable container 2 is in this case again in a section (cutting plane rotated by 90 ° about the vertical axis with respect Fig. 1c ). Shown here is a section through the disposable container 2 along the channel, as in FIGS. 1b and 1c was shown.
  • the pumping and mixing device 1 connected pressure-tight by means of a screw thread, wherein the front part of a housing 4 of the pumping and mixing device and the outlet have complementary screw threads.
  • the pumping and mixing device itself shows a conveyor shaft 3, which is inserted almost to the end in the gutter of the disposable container.
  • This conveyor shaft which is designed here as a spiral, has far beyond the housing 4 of the pumping and mixing device.
  • the spiral can have a decreasing spiral spacing in the direction x, that is to say the spiral spacing s1 is greater than the spiral spacing s2 in FIG Fig. 2a , In the present case, however, the spiral spacing is constant, but according to the medium to be conveyed a variation of the distance is possible.
  • the free end of the spiral 3a projects into the disposable container / storage container 2.
  • the pumping and mixing device 1 has a flow chamber 5, which is traversed by the conveyor shaft 3, a metering window 12 is provided for checking the delivery conditions.

Description

Die vorliegende Erfindung betrifft eine Pump- und Mischvorrichtung für pulver- bzw. rieselförmige Medien sowie ein System zur Bereitstellung pastöser Medien für Bauzwecke.The present invention relates to a pumping and mixing device for powdered or free-flowing media and a system for providing pasty media for construction purposes.

Aufgrund des wachsenden Kostendruckes im Bausektor ist es wünschenswert, dass pastöse Medien, wie beispielsweise verarbeitungsfertig aufbereiteter Putz bzw. Gips kostengünstig und dem Bedarf des Verarbeiters angepasst auf der Baustelle zur Verfügung gestellt wird.Due to the growing cost pressure in the construction sector, it is desirable that pasty media, such as ready-to-use prepared plaster or plaster is provided inexpensively and adapted to the needs of the processor on site.

Eine Möglichkeit hierzu ist, das bereits vorgemischte pastöse Medium in entsprechenden Metallsilos an der Baustelle zur Verfügung zu stellen. Problematisch hierbei ist allerdings, dass hierfür sehr hohe Transportkosten anfallen, außerdem verlangen diese aus Metall gefertigten Silos eine kostenaufwendige Konstruktion, so dass hier relativ viel Kapital an der Baustelle gebunden ist. Weiterhin problematisch ist, dass diese bekannten Silos sehr groß sind und, beispielsweise wenn diese nur zur Hälfte aufgebraucht werden, weitere Kostennachteile entstehen.One possibility for this is to provide the already premixed pasty medium in corresponding metal silos at the construction site. The problem here, however, is that this very high transport costs In addition, these silos made of metal require a costly construction, so that here relatively much capital is tied to the site. Another problem is that these known silos are very large and, for example, if they are only half consumed, further cost disadvantages arise.

Es ist auch möglich, das entsprechende pastöse Medium ausgehend von pulverförmigen Material direkt an der Baustelle anzumischen. Hierbei ist problematisch, dass ein kontinuierliches Verarbeiten pulverförmiger Medien an der Baustelle bisher sehr aufwendig ist. So ist beispielsweise erhöhte Aufmerksamkeit des Bedienpersonals notwendig, in einem abgestimmten Mischungsverhältnis pulverförmiges Medium mit Wasser zu mischen, um hieraus ein pastöses Medium zu erhalten.It is also possible to mix the corresponding pasty medium starting from powdery material directly at the site. Here it is problematic that a continuous processing of powdered media at the site has been very expensive. For example, increased operator attention is required to mix powdered medium with water in a tuned mixing ratio to obtain a pasty medium therefrom.

Dokument EP-A-0 147 631 offenbart eine Pump- und Mischvorrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1. Dokument DE-A-196 17 423 offenbart eine Pump- und Mischvorrichtung enthaltend eine kragende Förderwelle.document EP-A-0 147 631 discloses a pumping and mixing device having the features of the preamble of claim 1. Document DE-A-196 17 423 discloses a pumping and mixing device including a cantilevered conveyor shaft.

Ausgehend von diesem Stand der Technik ist es die Aufgabe der vorliegenden Erfindung, eine Pump- und Mischvorrichtung für pulver- bzw. rieselförmige Medien sowie ein System zur Bereitstellung pastöser Medien für Bauzwecke zu schaffen, welches ausgehend von einem angelieferten pulverförmigen Medium auf eine kostengünstige und einfache Weise die kontinuierliche Herstellung pastösen Mediums für den Baubereich ermöglicht.Based on this prior art, it is the object of the present invention to provide a pumping and mixing device for powdered or free-flowing media and a system for providing pasty media for construction purposes, which starting from a supplied powdery medium to a cost-effective and simple Way the continuous production of pasty medium for the construction sector allows.

Diese Aufgabe wird die Gegenstände der unabhängigen Patentansprüche gelöst.This object is achieved by the subject matters of the independent patent claims.

Die erfindungsgemäße Pump- und Mischvorrichtung für pulver- bzw. rieselförmige Medien, welche zur Anbindung an ein Lagerbehältnis wie beispielsweise ein Einwegcontainer geeignet ist, enthält

  • eine Förderwelle zum Einführen in das Lagerbehältnis,
  • ein zumindest einen Teil der Förderwelle umgebendes Gehäuse, welches
  • eine Dosierkammer aufweist und der Dosierkammer nachgeordnet eine Mischkammer, welche eine
  • mit der Förderwelle fluchtende und kraftübertragend verbundene Mischwelle (8) beherbergt sowie einen Wasseranschluss zum Mischen des Mediums mit Wasser unter Bildung einer pastösen Masse enthält und
  • anschließend einen Ausgang zum Anschluss einer Fördervorrichtung zum Weiterfördern der pastösen Masse.
The inventive pumping and mixing device for powdered or free-flowing media, which is suitable for connection to a storage container such as a disposable container, contains
  • a conveyor shaft for insertion into the storage container,
  • a housing surrounding at least a part of the conveyor shaft, which
  • a metering chamber and the metering chamber downstream of a mixing chamber, which a
  • accommodated with the conveyor shaft aligned and force transmitting connected mixing shaft (8) and a water connection for mixing the medium with water to form a pasty mass contains and
  • then an output for connection of a conveying device for further conveying the pasty mass.

Hierbei ist die Förderwelle dazu geeignet, in das Lagerbehältnis eingefügt bzw. eingeführt zu werden, um somit pulver- bzw. rieselförmiges Medium möglichst kontinuierlich aus diesem geschlossenen Behältnis heraus zu fördern. Dieses gelangt dann gegebenenfalls in eine Vorlaufkammer, wodurch eine gewisse Vergleichmäßigung des Förderprozesses erreicht werden kann.Here, the conveyor shaft is adapted to be inserted or introduced into the storage container, thus promoting powdered or free-flowing medium as continuously as possible from this closed container out. This then optionally passes into a flow chamber, whereby a certain homogenization of the delivery process can be achieved.

Das von der erfindungsgemäßen Pump- und Mischvorrichtung abweisende freie Ende der Förderwelle ist in das Lagerbehältnis kragend ausgeführt. Ein am entgegengesetzten Ende der Mischkammer (also von dem freien Ende der Förderwelle weg weisend) angebrachter gemeinsamer Antrieb für die Misch- und Förderwelle bewirkt den Antrieb. Dies ist vorteilhaft gegenüber "beidseitig aufgehängten" Förderwellen, welche schwer im Lagerbehältnis fixierbar sind (insbesondere wenn es sich um einen Einwegcontainer handelt) bzw. bei denen die Förderwelle zwangsläufig Teil des Behältnisses sein muss. Mit der vorliegenden Vorrichtung kann ein herauskragendes Ende der Förderwelle für sich genommen in ein Lagerbehältnis wie einen Einwegcontainer oder dergleichen eingeführt werden, der entsprechende Antrieb erfolgt von der "Rückseite" der Vorrichtung aus.The deflecting from the pumping and mixing device according to the invention free end of the conveyor shaft is designed to crimp into the storage container. A common drive for the mixing and conveying shaft mounted at the opposite end of the mixing chamber (ie pointing away from the free end of the conveyor shaft) effects the drive. This is advantageous over "on both sides suspended" conveyor shafts, which are difficult to fix in the storage container (especially if it is a disposable container) or where the conveyor shaft must necessarily be part of the container. With the present device, a projecting end of the conveyor shaft Taken individually, they are inserted into a storage container such as a disposable container or the like, the corresponding drive being made from the "back" of the device.

Vorteilhafterweise weist das Gehäuse der Pump- und Mischvorrichtung eine Vorlaufkammer auf, wobei dieser Vorlaufkammer nachgeordnet die Dosierkammer angeordnet ist und die Dosierkammer gegenüber der Vorlaufkammer zumindest bereichsweise querschnittsreduziert ist.Advantageously, the housing of the pumping and mixing device has a flow chamber, wherein this flow chamber downstream of the metering chamber is arranged and the metering chamber is compared to the flow chamber at least partially reduced in cross-section.

Diese Vorlaufkammer ist allerdings nicht zwingend notwendig, insbesondere wenn dafür andere Merkmale gegeben sind. So hat es sich beispielsweise gezeigt, dass bei einem "Hineinragen" der Dosierkammer in das Lagerbehältnis selbst eine gesonderte Vorlaufkammer nicht notwendig ist. Dies liegt daran, dass eine entsprechende Querschnittserweiterung dann schon im Lagerbehältnis selbst gegeben ist. Es wird dann von einem "Vorlaufbereich" gesprochen, welcher die Vorlaufkammer ersetzt. Vom Vorlaufbereich, welcher im Lagerbehältnis untergebracht ist, gibt es naturgemäß eine Querschnittsreduzierung zum Inneren der Dosierkammer hin. Hierbei ist es besonders vorteilhaft, dass die Dosierkammer an dem der Mischkammer abgewandten Ende den Flansch der Pump- und Mischvorrichtung zu dem Lagerbehältnis hin überragt. D.h., dass er beispielsweise das Schraubgewinde oder den Schnellverschluss überragt, so dass sichergestellt ist, dass das vorderste Ende der Dosierkammer ebenfalls in das Lagerbehältnis selbst reicht bzw. kragt, um so einen erfindungsgemäßen Vorlaufbereich zu erzielen.However, this flow chamber is not absolutely necessary, especially if other characteristics are given for it. Thus, it has been found, for example, that when a "protruding" of the metering chamber into the storage container itself, a separate flow chamber is not necessary. This is because a corresponding cross-sectional widening is already given in the storage container itself. It is then spoken of a "flow area", which replaces the flow chamber. From the flow area, which is housed in the storage container, there is naturally a cross-sectional reduction to the interior of the dosing out. It is particularly advantageous that the metering chamber at the end facing away from the mixing chamber projects beyond the flange of the pumping and mixing device to the storage container. In other words, it projects beyond, for example, the screw thread or the quick-action closure, so that it is ensured that the foremost end of the metering chamber likewise extends or projects into the storage container itself, so as to achieve a flow area according to the invention.

Dem Vorlaufbereich bzw. der Vorlaufkammer nachgeordnet ist dann eine Dosierkammer, welche zumindest bereichsweise querschnittsreduziert ist gegenüber der Vorlaufkammer bzw. dem Vorlaufbereich. Es hat sich gezeigt, dass durch diese zwischengeordnete Kammer eine weitere Vergleichsmäßigung der Förderung erreicht wird.Downstream of the flow area or the flow chamber is then a metering chamber, which at least partially reduced cross-section is compared to the flow chamber or the flow area. It has been shown that a further equalization of the promotion is achieved by this intermediate chamber.

Der Dosierkammer nachgeordnet ist dann eine Mischkammer gegeben, welche zu der Dosierkammer hin querschnittsverringert offen ist. Die Förderwelle, welche sich bis in die bzw. durch die Dosierkammer erstreckt, ist mit einer Mischwelle kraftübertragend verbunden. Diese Mischwelle sorgt in der Mischkammer dazu, dass aus einem Wasseranschluss, welcher in die Mischkammer mündet, Wasser bereitgestellt wird zum Mischen des pulver- bzw. rieselförmigen Mediums mit Wasser zu einer pastösen Masse. Anschließend an die Mischkammer ist schließlich ein Anschluss zum Weiterfördern der pastösen Masse gegeben, so dass die Masse druckbehaftet auf in höhere Etagen eines Gebäudes weitergefördert werden kann und somit direkt zum Verarbeiter hin gebracht werden kann.Downstream of the metering chamber is then given a mixing chamber, which is open cross-sectionally reduced towards the metering chamber. The conveyor shaft, which extends into or through the metering chamber, is connected to transmit power to a mixing shaft. This mixing shaft ensures in the mixing chamber that from a water connection, which opens into the mixing chamber, water is provided for mixing the powdered or free-flowing medium with water to a pasty mass. Subsequent to the mixing chamber, a connection for conveying the pasty mass is finally given, so that the mass pressure can be further promoted to higher floors of a building and thus can be brought directly to the processor out.

Diese erfindungsgemäße Pump- und Mischvorrichtung ist insbesondere interessant in Verbindung mit einem Einwegcontainer zur Bereitstellung pulver- und rieselförmiger Medien, wie dieser beispielsweise in der DE 20 2004 010 486 der selben Anmelderin offenbart ist. Ein solcher Container ist vorzugsweise aus Materialien wie Wellpappe aufgebaut und weist somit ein sehr geringes Eigengewicht auf. Der Container ist hierbei insbesondere für die Aufnahme der Förderwelle ausgelegt, so dass sich hier ein kontinuierlicher Pulverfluss sowie eine gute Restentleerung ergibt. Alternativ zu dem oben genannten Einwegcontainer nach der DE 20 2004 010 486 können selbstverständlich auch weitere auf die Anmelderin zurückgehende Einwegcontainer, beispielsweise nach der DE 103 14 146 A1 , der DE 202 13 063 U1 oder der EP 03 09 0261 A1 zur Anwendung kommen.This pumping and mixing device according to the invention is particularly interesting in connection with a disposable container for providing powdered and free-flowing media, as this example in the DE 20 2004 010 486 the same applicant is disclosed. Such a container is preferably constructed of materials such as corrugated cardboard and thus has a very low weight. The container is in this case designed in particular for receiving the conveyor shaft, so that here results in a continuous flow of powder and a good emptying. Alternatively to the above-mentioned one-way container after the DE 20 2004 010 486 of course, other disposable containers going back to the applicant, for example, after DE 103 14 146 A1 , of the DE 202 13 063 U1 or the EP 03 09 0261 A1 come into use.

Vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen angegeben.Advantageous developments are specified in the dependent claims.

Eine vorteilhafte Weiterbildung der Pump- und Mischvorrichtung sieht vor, dass das Vorderteil des Gehäuses im Wesentlichen druckdicht an das Lagerbehältnis/den Einwegcontainer mittels eines Schraubgewindes, eines Schnellverschlusses oder dergleichen anschließbar ist. Hierdurch ergibt sich eine genormte Anschlussstelle, die Bereitstellung pulverförmigen Materials ist kontinuierlich durch diese sichere Verbindung gegeben.An advantageous development of the pumping and mixing device provides that the front part of the housing is substantially pressure-tight to the storage container / the disposable container by means of a screw thread, a quick release or the like connected. This results in a standardized connection point, the provision of powdered material is continuously given by this secure connection.

Eine weitere vorteilhafte Weiterbildung sieht vor, dass die Förderwelle als Förderschnecke ausgeführt ist. Alternativ kann die Förderwelle auch als Spirale ausgeführt sein. Diese Spiralform ist extrem vorteilhaft zur Auflockerung des pulver- und rieselförmigen Materials im Container. Da die Spirale relativ weit unten in dem Lagerbehältnis/Einwegcontainer eingreift, ist der Druck durch das Material selbst sehr hoch, es kommt hier üblicherweise zu Verdichtungen durch eigengewichtsbedingte Verdichtungen. Hier wird durch die Spirale gewährleistet, dass es hier zu einer Auflockerung kommt, durch die in dem Einwegcontainer gegebenen Gefälle (s. einleitend in Bezug genommene Anmeldungen der Anmelderin) kommt es zu einem von der Spirale unterstützten Herausführen des pulverförmigen Materials aus dem Einwegcontainer.A further advantageous embodiment provides that the conveyor shaft is designed as a screw conveyor. Alternatively, the conveyor shaft can also be designed as a spiral. This spiral shape is extremely advantageous for loosening up the powdery and free-flowing material in the container. Since the spiral engages relatively far down in the storage container / disposable container, the pressure by the material itself is very high, it usually comes to compression due to self-weight compaction. Here is ensured by the spiral, that it comes here to a loosening, by the given in the one-way container slope (s., Applicant's applications referred to in the introduction), it comes to a assisted by the spiral lead out of the powdery material from the disposable container.

Diese Spirale kann auf verschiedene Weisen ausgeführt sein. So können beispielsweise zusätzliche Leitbleche für pulverförmiges Material gegeben sein, welche auch (nicht unbedingt gewünschte) Versteifung der Spirale bewirken können. Vorteilhaft ist außerdem ein kleiner werdender Spiralabstand der Spirale in Richtung von dem Lagerbehältnis fort, wodurch sich ebenfalls die Gefahr von Verstopfungen verringert.This spiral can be made in various ways. Thus, for example, additional baffles for powdery material may be present, which may also cause (not necessarily desired) stiffening of the spiral. Also advantageous is a decreasing spiral distance of the spiral in the direction of the storage container, which also reduces the risk of blockages.

Besonders vorteilhaft ist, dass das freie Ende der Förderwelle (vorzugsweise wenn dieses als Spirale ausgeführt ist) frei in das Lagerbehältnis kragend ausgeführt ist. Hierdurch kommt es zu einer "Selbstzentrierung" der Schnecke, selbst wenn diese eine gewisse Biegeelastizität aufweist, ist eine sehr gute Funktion gegeben. Alternativ (allerdings mit höheren Kosten verbunden und nicht unbedingt vorteilhaft) ist eine Aufnahme/Lagerung des freien Endes im Lagerbehältnis/Einwegcontainer möglich.It is particularly advantageous that the free end of the conveyor shaft (preferably when this is designed as a spiral) is cantilevered in the storage container. This results in a "self-centering" of the screw, even if this has a certain bending elasticity, a very good function is given. Alternatively (but with higher costs and not necessarily advantageous) is a recording / storage of the free end in the storage container / disposable container possible.

Eine weitere vorteilhafte Weiterbildung sieht vor, dass die Vorlaufkammer ein Kontroll- und Dosierfenster aufweist. Hierdurch ist jederzeit im Betrieb eine Überprüfung des Pulverflusses möglich.A further advantageous embodiment provides that the flow chamber has a control and metering window. This makes it possible to check the powder flow at any time during operation.

Eine weitere vorteilhafte Weiterbildung sieht vor, dass die bereichsweise Querschnittsverringerung der Dosierkammer als zur Vorlaufkammer hin trennende Schottwand ausgeführt ist, in deren Zentrum die Förderwelle frei drehbar ist. Die Förderwelle geht somit durch Vorlaufkammer und die sich daran anschließende Dosierkammer, die dazwischenliegende (zu der Dosierkammer gehörende) Schottwand bewirkt hierbei ein Vergleichmäßigung der Förderung, im zentralen Bereich der Dosierkammer ist ein Durchgang vorgesehen, in welchem die Förderwelle/Spirale frei drehbar ist.A further advantageous embodiment provides that the region-wise reduction in cross-section of the metering chamber is designed as a partition wall separating the flow chamber, in whose center the conveyor shaft is freely rotatable. The conveyor shaft thus passes through the inlet chamber and the adjoining metering chamber, the intervening (belonging to the metering chamber) bulkhead in this case causes a homogenization the promotion, in the central region of the dosing a passage is provided in which the conveyor shaft / spiral is freely rotatable.

Es hat sich gezeigt, dass das Verhältnis von engster Querschnittsfläche in der Dosierkammer (also beispielsweise der engste Querschnitt der oben genannten Schottwand) der größten Querschnittsfläche in der Vorlaufkammer zwischen 0,01 und 0,5 beträgt.It has been found that the ratio of the narrowest cross-sectional area in the metering chamber (that is, for example, the narrowest cross section of the abovementioned bulkhead) of the largest cross-sectional area in the flow chamber is between 0.01 and 0.5.

Eine weitere vorteilhafte Weiterbildung sieht vor, dass im Bereich des Endes Dosierkammer ein Spaltraum zum Überleiten von Medium von der Dosierkammer in die Mischkammer vorgesehen ist. Dieser kann auf verschiedene Weisen ausgeführt sein, entscheidend ist, dass hier eine Anbildung der Förderwelle an die sich anschließende Mischwelle ermöglicht wird und gleichzeitig ein kontinuierlicher Fluss von Pulver durch diesen Spaltraum hindurch. Der Spaltraum ist beispielsweise als Trommel mit axialen Ausnehmungen ausgeführt, welche sich an einer der Vorlaufkammer abgewandten Seite der Dosierkammer abstützt und vorzugsweise in die Mischkammer hineinragt.A further advantageous embodiment provides that in the region of the end of the metering chamber, a gap for the passage of medium from the metering chamber is provided in the mixing chamber. This can be carried out in various ways, it is crucial that here an attachment of the conveyor shaft is made possible to the subsequent mixing shaft and at the same time a continuous flow of powder through this gap space. The gap is designed, for example, as a drum with axial recesses, which is supported on a side facing away from the flow chamber of the metering chamber and preferably protrudes into the mixing chamber.

Besonders vorteilhaft an der vorliegenden Erfindung ist, dass auf einer sehr geringen Länge die Pulverförderung kontinuierlich folgt und sogar eine vollständige Mischung zu einer pastösen Masse erfolgt. Es hat sich gezeigt, dass hierfür auch das Längenverhältnis der einzelnen oben beschriebenen Kammern wichtig ist. So beträgt vorzugsweise das Verhältnis von Länge der Vorlaufkammer zur Länge der Dosierkammer zwischen 1 und 2. Das Verhältnis der Länge der Vorlaufkammer zur Länge der Mischkammer beträgt vorzugsweise zwischen 0,3 und 0,7.It is particularly advantageous with the present invention that powder conveyance follows continuously over a very short length and even complete mixing into a pasty mass takes place. It has been shown that this also the aspect ratio of the individual chambers described above is important. Thus, preferably the ratio of length of the flow chamber to the length of the metering chamber is between 1 and 2. The ratio of the length of the flow chamber to the length of the mixing chamber is preferably between 0.3 and 0.7.

Eine weitere vorteilhafte Weiterbildung sieht, dass im von der Vorlaufkammer abweisenden Endbereich der Förderwelle eine Mitnehmerverbindung zur Mischwelle gegeben ist. Alternativ ist eine Mitnehmerverbindung auch innerhalb der Förderwelle, insbesondere im Bereich der Vorlaufkammer, möglich. Durch diese mehrteilige Konstruktion sind die Herstellungs- und Wartungskosten vermindert.A further advantageous embodiment provides that in the end region of the conveyor shaft, which is repelled by the feed chamber, there is a driver connection to the mixing shaft. Alternatively, a driver connection is also possible within the conveyor shaft, in particular in the region of the flow chamber. By this multi-part construction, the manufacturing and maintenance costs are reduced.

In der Mischkammer selbst ist vorzugsweise mittig eine Mischwelle vorgesehen, welche Radialausleger aufweist. Diese können zum einem als radial nach außen gerichtet strebend zur Mischung von Medium (also Pulver und Wasser) bzw. als spiralförmige Ausleger zur Förderung von Medium von dem Lagerbehältnis fort ausgeführt sein. Durch die entsprechende Anpassung von Misch- und Förderauslegern ist hier eine Abstimmung entsprechend den gewünschten Verhältnissen (Körnung des Pulvers, davon pastösem Medium etc.) möglich. Eine entsprechende Anpassung durch Austausch der Mischwelle ist ebenfalls möglich.In the mixing chamber itself, a mixing shaft is preferably provided centrally, which has radial arms. These can be designed as a radially outwardly aspirant to the mixture of medium (ie powder and water) or as a spiral boom for conveying medium from the storage container on the one hand. Due to the corresponding adaptation of mixing and delivery jibs, a tuning according to the desired conditions (granulation of the powder, of which pasty medium, etc.) is possible. A corresponding adjustment by replacing the mixing shaft is also possible.

Eine besonders vorteilhafte Weiterbildung sieht vor, dass am Ende der Mischkammer, auf der der Vorlaufkammer abgewandten Seite der Vorrichtung ein gemeinsamer Antrieb für Misch- und Förderwelle angebracht ist. Sehr vorteilhaft hieran ist die Tatsache, dass Misch- und Förderwelle einachsig antreibbar sind, die Anordnung des Antriebs auf der der Förderwelle abweisenden Seite bietet außerdem den Vorteil, dass eine Selbstzentrierung der Förderwelle (gerade wenn diese als Spirale ausgeführt ist) leicht möglich ist. Ein weiterer Vorteil ist, dass an dieser Stelle ein Antrieb leicht montierbar ist, hierbei muss kein fest angebauter Antrieb vorgesehen sein, es können auch übliche auf dem Bau vorliegende Antriebe (selbst Bohrmaschinen) anschließbar sein.A particularly advantageous embodiment provides that at the end of the mixing chamber, on the side facing away from the flow chamber of the device, a common drive for mixing and conveying shaft is mounted. Very advantageous to this is the fact that mixing and conveying shaft are driven uniaxially, the arrangement of the drive on the conveyor shaft repellent side also offers the advantage that a self-centering of the conveyor shaft (especially if this is designed as a spiral) is easily possible. Another advantage is that at this point a drive is easy to install, this case no fixed mounted drive must be provided, it can also be common on the construction existing drives (even drills) can be connected.

Eine weitere vorteilhafte Weiterbildung sieht vor, dass an dem Ausgang zum Anschluss einer Fördereinrichtung zum Weiterfördern pastöser Massen eine Pumpvorrichtung, beispielsweise nach der EP 1 445 490 A1 der selben Anmelderin möglich ist. Hierdurch wird es möglich, dass das frisch gemischte pastöse Medium über beispielsweise 30 m Länge zu dem Arbeiter gelangen kann. Der modulare Aufbau bietet hier außerdem den Vorteil, dass die Pumpvorrichtung die Weiterförderung auch alternativ direkt an den Einwegcontainer, welche bereits vorgemischtes pastöses Medium enthalten, angeschlossen werden kann.A further advantageous embodiment provides that at the output for connecting a conveyor for conveying pasty masses a pumping device, for example according to the EP 1 445 490 A1 the same applicant is possible. This makes it possible that the freshly mixed pasty medium over 30 m, for example, can reach the worker. The modular design also offers the advantage here that the pumping device can alternatively also be connected directly to the disposable container, which already contains pre-mixed pasty medium.

Eine weitere vorteilhafte Ausführungsform sieht vor, dass die Pump- und Mischvorrichtung ein Gehäuse aufweist, welches in mindestens zwei Längsabschnitte teilbar ist. Hierdurch ist es möglich, beispielsweise eine "Dosiereinheit" (bestehend aus einem Gehäuseteil, welcher Dosierkammer und Vorlaufkammer enthält) und eine "Mischeinheit" (welche die Mischkammer enthält) zu trennen. Hierbei können diese Längsabschnitte auch schnell wieder miteinander verbunden werden, etwa durch eine Spannvorrichtung in Form einer Schnellspannvorrichtung bzw. einer bolzengespannten Spannvorrichtung.A further advantageous embodiment provides that the pumping and mixing device has a housing which is divisible into at least two longitudinal sections. This makes it possible, for example, a "metering unit" (consisting of a housing part, which contains the metering chamber and flow chamber) and a "mixing unit" (which contains the mixing chamber) to separate. These longitudinal sections can also be quickly connected to each other again, for example by a clamping device in the form of a quick-release device or a bolt-tensioned clamping device.

Das erfindungsgemäße System zur Bereitstellung pastöser Medien für Bauzwecke, enthaltend eine erfindungsgemäße Pump- und Mischvorrichtung sowie einen entsprechend abgestimmten Einwegcontainer bzw. ein Lagerbehältnis, welcher bzw. welches einen Anschluss zum Einführen der Förderwelle aufweist, hat ebenfalls vorteilhafte Weiterbildungen.The inventive system for providing pasty media for construction purposes, comprising a pumping and mixing device according to the invention and a correspondingly matched disposable container or a storage container, which or has a connection for introducing the conveyor shaft, also has advantageous developments.

Hierbei folgt die Containerform der erfindungsgemäßen Pump- und Mischvorrichtung, insbesondere im Bereich der Förderwelle bzw. des Anschlussflansches der Pump- und Mischvorrichtung an den Einwegcontainer bzw. das Lagerbehältnis. Besonders vorteilhaft ist hier, dass der Einwegcontainer fluchtend zur Förderwelle eine Sammelrinne aufweist. Diese Sammelrinne kann aus einem Extra-Kunststoffmaterial sein, beispielsweise als Kunststoffspritzgussteil ausgeführt sein, oder auch aus einfacher Pappe bestehen bzw. gegebenenfalls kunststoffbeschichtet sein bzw. mit einem aufgelegten Inliner versehen sein.In this case, the container shape of the pumping and mixing device according to the invention, in particular in the region of the conveying shaft or the connecting flange of the pumping and mixing device, follows the disposable container or the storage container. It is particularly advantageous here that the disposable container has a collecting channel in alignment with the conveying shaft. This collecting channel may be made of an extra plastic material, for example, be designed as a plastic injection molded part, or even consist of plain cardboard or optionally be plastic coated or be provided with an applied inliner.

Die Form der Rinne kann hierbei konisch bzw. flach sein, beides ist in Abstimmung auf die erfindungsgemäße Förderwelle möglich. Wichtig ist lediglich, dass innerhalb des Containers ein Gefälle (pyramidenförmig bei mehreckigen Querschnitten, im Wesentlichen konisch bei Rundquerschnitten des Containers) gegeben ist. Besonders vorteilhaft ist, dass die entsprechende Rinne auf voller Breite bzw. auf vollem Durchmesser des Containers verläuft.The shape of the channel can be conical or flat, both are possible in coordination with the conveyor shaft according to the invention. It is only important that within the container a slope (pyramidal in polygonal cross-sections, essentially conical in circular cross-sections of the container) is given. It is particularly advantageous that the corresponding channel extends to full width or full diameter of the container.

Es ist erstaunlich, dass die Breite der Rinne relativ gering sein muss. So ist das Verhältnis der größten Breite der Rinne zum größten Durchmesser der Förderwelle (innerhalb des Einwegcontainers) normalerweise zwischen 0,8 und 2,5, vorzugsweise zwischen 0,9 und 1,5.It is amazing that the width of the gutter has to be relatively small. Thus, the ratio of the largest width of the channel to the largest diameter of the conveyor shaft (within the one-way container) is normally between 0.8 and 2.5, preferably between 0.9 and 1.5.

Fig. 1a zeigt einen Einwegcontainer als Lagerbehältnis zur Anbindung einer erfindungsgemäßen Pump- und Mischvorrichtung. Hierbei zeigt Fig. 1a eine Vorderansicht eines solchen Containers, welcher auf eine Euro-Palette oder eine andere Industrie-Palette (zur Zeit CP3-Palette) geschnürt ist. Der Container hat zum Beispiel einen achteckigen Querschnitt, es sind allerdings auch andere mehreckige Querschnitte oder auch runde Querschnitte möglich. Fig. 1a shows a disposable container as a storage container for connection to a pumping and mixing device according to the invention. This shows Fig. 1a a front view of such a container, which is on a Euro pallet or other industrial range (currently CP3 range) laced. The container has, for example, an octagonal cross-section, but other polygonal cross-sections or round cross-sections are also possible.

Der Fig. 1a gezeigte Container ist mit Putz- Trockenmaterial (also pulverförmig) gefüllt. Der Einwegcontainer 2 weist einen Anschluss 16 wie eine erfindungsgemäße Pump- und Mischvorrichtung auf.Of the Fig. 1a shown container is filled with plaster dry material (ie powdered). The disposable container 2 has a connection 16 as a pumping and mixing device according to the invention.

Fign. 1b und 1c zeigen Schnitte des in Fig. 1a gezeigten Einwegcontainers. Hierbei zeigt Fig. 1b einen Schnitt parallel zur Standfläche (also zur Euro-Palette in Fig. 1a). FIGS. 1b and 1c show cuts of in Fig. 1a shown disposable container. This shows Fig. 1b a section parallel to the stand area (ie the euro pallet in Fig. 1a ).

Fig. 1c zeigt einen Schnitt senkrecht durch die Euro-Palette, in Hochachsenrichtung des Einwegcontainers. Fig. 1c shows a section perpendicular through the Euro-pallet, in the vertical axis direction of the disposable container.

In diesen Schnitten ist zu sehen, dass der Container einen inneren Trichter aufweist, welcher in eine Rinne mündet, welche im Wesentlichen die volle Breite des Einwegcontainers einnimmt. Am Ende dieser Rinne ist der Anschluss 16 gegeben. Das in dem Container gelagerte pulverförmige Medium wird durch das Eigengewicht selbst in Richtung der Rinne gepresst, wodurch es durchaus zu Verdichtungen im Bereich der Rinne kommen kann. Die Rinne selbst kann verschiedene Querschnittsformen aufweisen, beispielsweise die im Wesentlichen halbkreisförmige Querschnittsform 20a oder auch die flache bzw. ebene Querschnittsform 20b.In these sections, it can be seen that the container has an inner funnel, which opens into a channel, which occupies substantially the full width of the disposable container. At the end of this channel the connection 16 is given. That in the container stored powdery medium is pressed by the weight itself in the direction of the gutter, which can certainly lead to compaction in the gutter. The channel itself may have different cross-sectional shapes, for example, the substantially semicircular cross-sectional shape 20a or the flat or planar cross-sectional shape 20b.

Wegweisend für den Einwegcontainer ist, dass dieser aus einem Einwegmaterial wie beispielsweise Pappe hergestellt sein kann und daher entsprechend leichtgewichtig ist. Der Aufbau des Einwegcontainers ist auf verschiedene Weisen möglich, beispielsweise durch vorgefertigte Kunststoffteile oder auch durch Abstützkonstruktionen, welche aus beschichteter Pappe sein können oder (wenn nötig) mit einem Inliner überzogen sein können.A pioneer of the disposable container is that it can be made of a disposable material such as cardboard and therefore is correspondingly lightweight. The construction of the disposable container is possible in various ways, for example by prefabricated plastic parts or by support structures, which may be made of coated cardboard or (if necessary) may be coated with an inliner.

Bezüglich weiterer Einzelheiten des Einwegcontainers wird auf die DE 20 2004 010 486 , der DE 103 14 146 A1 , der DE 202 13 063 U1 oder der EP 03 09 0261 A1 verwiesen.For further details of the disposable container is on the DE 20 2004 010 486 , of the DE 103 14 146 A1 , of the DE 202 13 063 U1 or the EP 03 09 0261 A1 directed.

Fign. 2a und 2b zeigen verschiedene Schnitte durch die erfindungsgemäße Pump- und Mischvorrichtung. FIGS. 2a and 2 B show different sections through the pumping and mixing device according to the invention.

Dies ist eine Pump- und Mischvorrichtung 1 für pulver- bzw. rieselförmige Medien, insbesondere zur Anbindung an ein Einwegcontainer 2. Der Einwegcontainer 2 ist hierbei nochmals in einem Schnitt (Schnittebene um 90° um die Hochachse gedreht bezüglich Fig. 1c) gezeigt. Gezeigt ist hier also ein Schnitt durch den Einwegcontainer 2 entlang der Rinne, wie sie in Fign. 1b und 1c gezeigt wurde. An den Auslass 16 die erfindungsgemäße Pump- und Mischvorrichtung 1 druckdicht mittels eines Schraubgewindes angeschlossen, wobei das Vorderteil eines Gehäuses 4 der Pump- und Mischvorrichtung und der Auslass komplementäre Schraubgewinde aufweisen.This is a pumping and mixing device 1 for powder or free-flowing media, in particular for connection to a disposable container 2. The disposable container 2 is in this case again in a section (cutting plane rotated by 90 ° about the vertical axis with respect Fig. 1c ). Shown here is a section through the disposable container 2 along the channel, as in FIGS. 1b and 1c was shown. At the outlet 16, the pumping and mixing device 1 according to the invention connected pressure-tight by means of a screw thread, wherein the front part of a housing 4 of the pumping and mixing device and the outlet have complementary screw threads.

Die Pump- und Mischvorrichtung selbst zeigt eine Förderwelle 3, welche fast bis zum Ende in die Rinne des Einwegcontainers eingeführt ist. Diese Förderwelle, welche vorliegend als Spirale ausgeführt ist, weist weit über das Gehäuse 4 der Pump- und Mischvorrichtung hinaus. Die Spirale kann hierbei in Richtung x einen kleiner werdenden Spiralabstand aufweisen, das heißt der Spiralabstand s1 ist größer als der Spiralabstand s2 in Fig. 2a. Vorliegend ist der Spiralabstand jedoch gleich bleibend, entsprechend dem zu fördernden Medium ist aber eine Variation des Abstands möglich. Das freie Ende der 3a der Spirale kragt in den Einwegcontainer/das Lagerbehältnis 2 aus.The pumping and mixing device itself shows a conveyor shaft 3, which is inserted almost to the end in the gutter of the disposable container. This conveyor shaft, which is designed here as a spiral, has far beyond the housing 4 of the pumping and mixing device. In this case, the spiral can have a decreasing spiral spacing in the direction x, that is to say the spiral spacing s1 is greater than the spiral spacing s2 in FIG Fig. 2a , In the present case, however, the spiral spacing is constant, but according to the medium to be conveyed a variation of the distance is possible. The free end of the spiral 3a projects into the disposable container / storage container 2.

Gezeigt ist also ein System zur Bereitstellung pastöser Medien für Bauzwecke, enthaltend eine Pump- und Mischvorrichtung 1 sowie einen Einwegcontainer 2 zur Bereitstellung pulver- oder rieselförmiger Medien.Shown is a system for providing pasty media for construction purposes, comprising a pumping and mixing device 1 and a disposable container 2 for providing powdered or free-flowing media.

Im Folgenden wird insbesondere auf die Einzelheiten der erfindungsgemäßen Pump- und Mischvorrichtung nochmals näher eingegangen. Die Pump- und Mischvorrichtung 1 weist eine Vorlaufkammer 5 auf, welche von der Förderwelle 3 durchzogen ist, ein Dosierfenster 12 ist vorgesehen zur Überprüfung der Förderverhältnisse. An die Vorlaufkammer 5 schließt sich eine Dosierkammer 6 an. Diese Dosierkammer weist hierbei eine Trennwand 13 mit einem dahinter liegenden Zylinderraum auf, welcher deutlich querschnittsverringert ist gegenüber der Vorlaufkammer. Diese Schottwand ist kreisringförmig gestaltet, so dass zentral die Förderwelle 3 hindurchgehen kann. Die Schottwand wird vorliegend als Teil der Dosierkammer verstanden.The details of the pumping and mixing device according to the invention will be discussed in more detail below. The pumping and mixing device 1 has a flow chamber 5, which is traversed by the conveyor shaft 3, a metering window 12 is provided for checking the delivery conditions. To the flow chamber 5, a metering chamber 6 connects. This metering chamber in this case has a partition wall 13 with a cylinder space behind it, which is significantly reduced in cross-section with respect to the flow chamber. This bulkhead is designed circular, so that centrally the conveyor shaft 3 can go through. The bulkhead is understood in the present case as part of the metering chamber.

Das Verhältnis von engster Querschnittsfläche in der Dosierkammer 6 (also der zentrale Bereich der Schottwand) zur größten Querschnittsfläche in der Vorlaufkammer beträgt vorliegend etwa 0,04. Weitergehend in positive x-Richtung ist am Ende des Zylinderraumes bzw. der Dosierkammer ein weiterer Spaltraum gegeben. Dieser Spaltraum 14 ist zum Überleiten von Medium von der Dosierkammer 6 in die Mischkammer 7 vorgesehen. Es handelt sich hierbei wiederum um eine Schottwand, welche ein Durchführen der Förderwelle 3 ermöglicht. Linksseitig (also in positive x-Richtung) ist eine Trommel 17 zu sehen, welche axiale Ausnehmungen aufweist, welche sich an der der Vorlaufkammer 5 abgewandten Seite der Dosierkammer 6 (bzw. an der dort befindlichen Wand/Schottwand) befinden. Hierdurch wird ein Materialtransport durch die Dosierkammer hin zu der Mischkammer ermöglicht. Der Spaltraum kann auf verschiedene Weisen ausgeführt sein. Beispielhaft ist die trommelartige Anordnung gezeigt, welche durch den Schnitt A-A (s. Fig. 2b) nochmals verdeutlicht ist. Je nach Materialeigenschaften, beispielsweise der Körnung des Pulvers bzw. des rieselförmigen Mediums, können hier Anpassungen der Spaltmaße vorgenommen werden.The ratio of the narrowest cross-sectional area in the metering chamber 6 (ie the central region of the bulkhead) to the largest cross-sectional area in the flow chamber is presently about 0.04. Continuing in the positive x-direction, a further gap is provided at the end of the cylinder space or dosing chamber. This gap space 14 is provided for transferring medium from the metering chamber 6 into the mixing chamber 7. Again, this is a bulkhead, which allows the conveyor shaft 3 to be passed through. On the left side (ie in the positive x direction), a drum 17 can be seen, which has axial recesses which are located on the side of the metering chamber 6 facing away from the flow chamber 5 (or at the wall / bulkhead wall located there). As a result, a material transport through the metering chamber is made possible to the mixing chamber. The gap can be made in various ways. By way of example, the drum-like arrangement is shown, which by the section AA (s. Fig. 2b ) is again clarified. Depending on the material properties, for example the grain size of the powder or of the free-flowing medium, adjustments of the gap dimensions can be made here.

An die Dosierkammer schließt sich also in positiver x-Richtung eine Mischkammer 7 an. Diese weist einen Wasseranschluss 9 zur Zuführung von Flüssigkeit in die Mischkammer auf, in welcher eine Vermischung des in der Mischkammer geförderten pulverförmigen Materials mit Wasser, unter Bildung eines pastösen Mediums, möglich ist. Im von der Vorlaufkammer 5 abweisenden Endbereich der Förderwelle 3 ist über eine Mitnehmerverbindung eine Mischwelle 8 angebracht. Diese Mischwelle weist Radialausleger auf, welche als radial nach außen gerichtete Streben 8a zur Mischung von Medium oder auch als spiralförmige Ausleger 8b zur Förderung von Medium von dem Lagerbehältnis fort (also in x-Richtung) ausgeführt sind.Thus, a mixing chamber 7 adjoins the metering chamber in the positive x-direction. This has a water connection 9 for the supply of liquid in the mixing chamber, in which a mixing of the conveyed in the mixing chamber powdery material with water, to form a pasty medium, is possible. In the repellent from the flow chamber 5 end portion of the conveyor shaft 3 is via a driver connection a mixing shaft 8 is attached. This mixing shaft has radial arms, which are designed as radially outwardly directed struts 8a for mixing medium or as spiral-shaped arms 8b for conveying medium away from the storage container (ie in the x direction).

Am Ende der Mischkammer 7, auf der der Vorlaufkammer 5 abgewandten Seite der Vorrichtung ist ein gemeinsamer Antrieb für Misch- und Förderwelle angebracht, an welchem Antriebe ankoppelbar sind, um somit Förder- und Mischwelle gleichzeitig betreiben und regeln zu können. Hierbei sind Förder- und Mischwelle in ihrer Geometrie so aufeinander abgestimmt, dass praktisch eine "Selbstregulierung" erfolgt, so dass lediglich mit der Motorgeschwindigkeit des angekoppelten Antriebs eine Erhöhung der Förderung folgen kann.At the end of the mixing chamber 7, on the side facing away from the flow chamber 5 of the device, a common drive for mixing and conveying shaft is attached to which drives can be coupled in order to simultaneously operate and regulate conveyor and mixing shaft. Here are conveyor and mixing shaft in their geometry coordinated so that virtually a "self-regulation" takes place, so that only with the motor speed of the coupled drive can increase the promotion.

Schließlich ist ein Ausgang 11 zum Anschluss einer Fördervorrichtung zum Weiterfördern der pastösen Masse vorgesehen.Finally, an exit 11 is provided for the connection of a conveying device for further conveying the pasty mass.

Vorliegend beträgt das Verhältnis der Länge der Vorlaufkammer 5 zur Länge der Dosierkammer 6 in x-Richtung etwa 1, 6 und das Verhältnis der Länge der Vorlaufkammer zur Länge der Mischkammer etwa 0,5.In the present case, the ratio of the length of the feed chamber 5 to the length of the metering chamber 6 in the x direction is about 1.6 and the ratio of the length of the feed chamber to the length of the mixing chamber is about 0.5.

Gezeigt ist also hier eine Pump- und Mischvorrichtung 1 für pulver- bzw. rieselförmige Medien zur Anbindung an ein Lagerbehältnis 2 (bzw. Einwegcontainer 2), enthaltend: eine Förderwelle zum Einführen in das Lagerbehältnis, ein zumindest einen Teil der Förderwelle umgebendes Gehäuse, welches eine Vorlaufkammer und dieser nachgeordnet eine gegenüber der Vorlaufkammer zumindest bereichsweise querschnittsreduzierte Dosierkammer aufweist und der Dosierkammer nachgeordnet eine Mischkammer, welche eine mit der Förderwelle kraftübertragend verbundene Mischwelle beherbergt sowie einen Wasseranschluss zum Mischen des Mediums mit Wasser unter Bildung einer pastösen Masse enthält und anschließend einen Ausgang zum Anschluss einer Fördervorrichtung zum Weiterfördern der pastösen Masse bzw. zum Einbringen in ein Transportbehältnis, z.B. in einem unter dem Ausgang stehenden Eimer.Shown here is a pumping and mixing device 1 for powder or free-flowing media for connection to a storage container 2 (or disposable container 2), comprising: a conveyor shaft for insertion into the storage container, a surrounding at least a portion of the conveyor shaft housing, which a preliminary chamber and this downstream of the flow chamber at least partially cross-section reduced metering chamber and downstream of the metering chamber a mixing chamber which accommodates a mixing shaft connected in a force-transmitting manner to the conveyor shaft and contains a water connection for mixing the medium with water to form a pasty mass and then an outlet for connection of a conveying device for conveying the pasty mass or for introduction into a transport container, eg a bucket under the exit.

Fign. 3a und 3b zeigen eine weitere Ausführungsform einer Rinne, welche im Sammelbereich eines Einwegcontainers 2 angeordnet sein kann. Bei dem in den Fign. 3a und 3b gezeigten Gegenstand handelt es sich um ein Kunststoffspritzgussteil, welches auf seiner Unterseite (in Fig. 3b als Oberseite gezeigt) einen im Wesentlichen halbzylindrischen Gegenstand hat, in welchen die Förderwelle einführbar ist. FIGS. 3a and 3b show a further embodiment of a channel, which can be arranged in the collecting area of a disposable container 2. In the in the FIGS. 3a and 3b The article shown is a plastic injection molded part, which on its underside (in Fig. 3b shown as the top) has a substantially semi-cylindrical object in which the conveyor shaft is insertable.

Fig. 4 zeigt eine Schnittansicht einer Pumpvorrichtung 15, wie sie an den Ausgang 11 zum Anschluss einer Fördereinrichtung beim Weiterfördern pastöser Massen anschließbar ist. Die Ankopplung erfolgt hier mit dem in Fig. 4 gezeigten rechtsseitigen Ende. Die Förderung erfolgt dann über eine Schnecke, das Weiterfördern erfolgt aus einem mittig nach unten in Fig. 4 zeigenden Ausgang. Ein entsprechender Zusatzantrieb zum Weiterfördern wird linksseitig der Pumpvorrichtung 15 angeflanscht. Fig. 4 shows a sectional view of a pumping device 15, as it can be connected to the output 11 for connection of a conveyor during further conveying pasty masses. The coupling takes place here with the in Fig. 4 shown right-hand end. The promotion then takes place via a screw, which is carried forward from a center down in Fig. 4 showing output. A corresponding additional drive for forwarding is flanged on the left side of the pump device 15.

Fign. 5a - 5c zeigen eine weitere Ausführungsform einer erfindungsgemäßen Pump- und Mischvorrichtung. Soweit nicht ausdrücklich etwa anderes gesagt ist, enthält diese Ausführungsform die Merkmale der oben beschriebenen ersten Ausführungsform. FIGS. 5a-5c show a further embodiment of a pumping and mixing device according to the invention. Unless expressly stated otherwise, this embodiment includes the features of the first embodiment described above.

Um Wiederholungen zu vermeiden wird im Folgenden daher lediglich auf die abweichenden Merkmale und deren besondere Bedeutung Bezug genommen.In order to avoid repetition, reference will therefore be made below only to the deviating features and their particular meaning.

Fig. 5a zeigt einen Schnitt durch die weitere Variante der erfindungsgemäßen Pump- und Mischvorrichtung. Eine der wesentlichen Abweichungen zur ersten Ausführungsform liegt darin, dass bei der in Fig. 5a gezeigten Ausführung eine Mitnehmerverbindung nicht in der Mischkammer gegeben ist, sondern dass die Förderwelle im Bereich der Vorlaufkammer eine solche Mitnehmerverbindung aufweist. Dies kann beim praktischen Betrieb der Anlage auf Baustellen sehr vorteilhaft sein: Fig. 5a shows a section through the further variant of the pumping and mixing device according to the invention. One of the essential deviations from the first embodiment is that in the case of the in Fig. 5a As shown embodiment, a driver connection is not given in the mixing chamber, but that the conveyor shaft in the region of the flow chamber has such a driver connection. This can be very advantageous in the practical operation of the system on construction sites:

Normalerweise wird vor dem Fördervorgang des in Fig. 5a gezeigte rechtsseitige Ende der Förderwelle zunächst einmal in den Einwegcontainer eingeführt. Hierzu sind verschiedene Varianten denkbar. Zum einen kann das rechtsseitige Ende der Förderwelle bereits werksseitig in dem Einwegcontainer angebracht sein, in diesem Fall wären dann durch ein entsprechendes Pfandsystem die Rückläufe der rechten Förderwellenenden zum Hersteller/Befüller der Einwegcontainer zu regeln.Normally, before the conveying process of in Fig. 5a shown right-side end of the conveyor shaft first inserted once in the disposable container. For this purpose, different variants are conceivable. On the one hand, the right-hand end of the conveyor shaft can already be factory-mounted in the disposable container, in which case the returns of the right conveyor shaft ends to the manufacturer / filler of the disposable containers would have to be regulated by a corresponding deposit system.

Eine andere Möglichkeit würde vorsehen, dass an den Anschluss 16, im Wesentlichen co-linear zu der Rinne 20a bzw. 20b verlaufend, sich eine Einführhilfe (z.B. ein Rohr) befindet, welche nicht mit pulverförmigem Material gefüllt ist, und welche geeignet ist, das rechtsseitige Förderwellenende zumindest partiell zu umschließen. Nach Einführen des rechten Förderwellenendes in den Einwegcontainer könnte dann durch Herausdrehen bzw. Herausziehen diese Einführhilfe herausgenommen werden und somit der Kontakt zwischen rechtem Förderwellenende und dem zu fördernden Trockengut hergestellt werden. Nach dieser "Fixierung" des rechten Förderwellenendes im Einwegcontainer könnte dann der Rest der Pump- und Mischvorrichtung angekoppelt werden, wobei gleichzeitig die rechtsseitige Flanschkupplung sowie die Mitnehmerverbindung 19 formschlüssig mit den jeweils komplementären Teilen verbunden werden, eine Sichtkontrolle kann hierbei durch das geöffnete Kontrollfenster 12' erfolgen.Another possibility would be to provide an insertion aid (eg a tube), which is not filled with powdery material, to the connection 16, running essentially co-linear with the channel 20a or 20b, and which is suitable for this purpose At least partially surround the right-side conveyor shaft end. After insertion of the right conveyor shaft end in the disposable container could then be removed by unscrewing or pulling out this insertion and thus the contact between right conveyor shaft end and the dry material to be conveyed are produced. After this "fixation" of the right conveyor shaft end in the disposable container then the rest of the pumping and mixing device could be coupled, at the same time the right side flange coupling and the driver connection 19 are positively connected to the respective complementary parts, a visual inspection can in this case by the open control window 12 ' respectively.

Herauszuheben bei Fig. 5a ist außerdem, dass sich an die Dosierkammer 6 kein "revolverförmiger" zweiter Spaltraum anschließt, wie dies bei der ersten Ausführungsform gegeben ist. In Fig. 5a ist außerdem gut zu sehen, dass die Förderwelle, welche die Dosierkammer durchläuft, kaum Spaltraum zu der inneren Dosierkammerwand aufweist. Dies wird zum einen dadurch gewährleistet, dass der Spaltraum zwischen der entsprechenden Förderwelle und der Dosierkammerinnenwand nur etwa 3 mm beträgt. Dieser Spaltabstand wird durch bereichsweise aufgebrachte Stahlplättchen weiter verringert, so dass sich hier fast ein Nullspalt ergibt, hierdurch ist ein "Abschaben" von Pulver bzw. Fördermittelresten an der Dosiermittelinnenwand gewährleistet.To highlight at Fig. 5a is also that adjoins the metering chamber 6 no "revolverförmiger" second gap space, as is given in the first embodiment. In Fig. 5a is also good to see that the conveyor shaft, which passes through the metering chamber, hardly has any gap space to the inner Dosierkammerwand. This is ensured on the one hand by the fact that the gap between the corresponding conveyor shaft and the metering chamber inner wall is only about 3 mm. This gap distance is further reduced by regionally applied steel platelets, so that there is almost a zero gap hereby, thereby a "scraping" of powder or conveying agent residues is ensured on the Dosiermittelinnenwand.

Weiter nach links, also zur Mischkammer hin, schließt sich dann die Mischwelle an die Förderwelle an. Die Mischwelle weist hierbei wiederum Radialausleger auf, wobei propellerartige Radialausleger 8b' für eine besonders gute Förderung sorgen, zusätzlich sind schräg stehende radiale Streben 8a' zur noch besseren Durchmischung vorgesehen. Diese relativ "dünnen" Radialstäbe können durch eine linienförmige Umfangsverstärkung 20 stabilisiert werden, diese Umfangsverstärkung 20 sorgt außerdem für ein "Abschaben" an der Mischkammerinnenwand und verhindert somit ein Anheften von Material.Further to the left, ie towards the mixing chamber, the mixing shaft then adjoins the conveyor shaft. The mixing shaft in this case again has radial arms, wherein propeller-like radial arms 8b 'provide for a particularly good promotion, in addition oblique radial struts 8a' are provided for even better mixing. These relatively "thin" radial bars can be stabilized by a line-shaped circumferential reinforcement 20, this circumferential reinforcement 20 also provides "scraping" of the mixing chamber inner wall and thus prevents attachment of material.

Linksseitig ist als (hier als schwarzes Rechteck erkennbar) wiederum die Ankupplung eines Antriebsmotors gezeigt, ein entsprechender Antriebsmotor (beispielsweise auf 230 V/1800 W-Basis, mit Ein- oder Zweigangrührwerk, stufenlos regelbar) ist anschließbar, hier allerdings aus Vereinfachungsgründen nicht gezeigt. Alternativ sind hier auch Drehstrommotore oder z.B. Verbrennungsmotore einsetzbar.On the left side is (as a black rectangle recognizable) turn the coupling of a drive motor shown, a corresponding drive motor (for example, on 230 V / 1800 W base, with single or twin agitator, infinitely variable) can be connected, but not shown here for reasons of simplification. Alternatively, three-phase motors or e.g. Combustion engines can be used.

Fig. 5b zeigt einen (weniger detaillierten) Schnitt durch dieselbe Anordnung. Besonders gut erkennbar sind hierbei der erste Längsabschnitt 4' sowie der zweite Längsabschnitt 4" des quer zur Längsrichtung geteilten Gehäuses, die Trennebene ist hierdurch "T" in der Zeichnung angedeutet. Fig. 5b shows a (less detailed) section through the same arrangement. In this case, the first longitudinal section 4 'and the second longitudinal section 4 "of the housing divided transversely to the longitudinal direction are particularly clearly recognizable; the parting plane is hereby indicated" T "in the drawing.

Fig. 5c zeigt eine Außenansicht der in Fig. 5a bzw. 5b gezeigten Ausführungsform. Hierbei ist ein Ständerfuß 18 erkennbar, welcher ein eigenständiges Abstützen der Pump- und Mischvorrichtung ermöglicht, so dass diese nicht (unter hoher Biegebelastung) direkt freitragend an den Container angeschlossen werden muss. Zu sehen ist außerdem hier eine als Bolzen gezeigte Spannvorrichtung 19, welche einen Zusammenhalt der Längsabschnitte 4' und 4" ermöglicht. Fig. 5c shows an outside view of in Fig. 5a or 5b shown embodiment. In this case, a stand base 18 can be seen, which enables independent support of the pumping and mixing device, so that it does not have to be connected to the container (under high bending load) directly cantilevered. It can also be seen here a clamping device 19 shown as a bolt, which allows a cohesion of the longitudinal sections 4 'and 4 ".

Fig. 6a zeigt einen Querschnitt eines Einwegcontainers mit einer im Sammelbereich angeordneten Rinne 20a, welche eine Breite b an ihrer breitesten Stelle aufweist. Die Rinne ist nach unten hin im Wesentlichen halbkreisförmig im Querschnitt ausgebildet. Fig. 6a shows a cross section of a disposable container with a channel arranged in the collecting channel 20a, which has a width b at its widest point. The channel is formed in a downward direction substantially semicircular in cross section.

Fig. 6b zeigt eine entsprechende Anordnung, wobei die Rinne 20b jedoch eine Ebene darstellt. Fig. 6b shows a corresponding arrangement, wherein the Gutter 20b, however, represents a plane.

Beide Rinnen können in einem entsprechenden Einwegcontainer angebracht sein. Wichtig ist hierbei lediglich, dass der Einwegcontainer zu der Sammelrinne, welche linienförmig ausgeführt ist, hin abfällt. Die Rinne kann sich hierbei über die gesamte Breite bzw. den gesamten Durchmesser des Einwegcontainers erstrecken. Die äußere Form des Einwegcontainers kann hierbei mehreckig oder auch rund sein.Both channels can be mounted in a corresponding disposable container. It is only important here that the disposable container drops to the collection trough, which is executed linear. The channel may extend over the entire width or the entire diameter of the disposable container. The outer shape of the disposable container may be polygonal or round.

Fign. 7a bis 10 zeigen eine weitere Ausführungsform der erfindungsgemäßen Pump- und Mischvorrichtung. Sämtliche der vorgenannten Angaben gelten auch für diese Pump- und Mischvorrichtung, sofern im Folgenden nichts anderes gesagt wird. FIGS. 7a to 10 show a further embodiment of the pumping and mixing device according to the invention. All of the above information also applies to this pumping and mixing device, unless otherwise stated below.

Es handelt sich bei der in Fig. 7a gezeigten Pump- und Mischvorrichtung (dort ohne Antrieb) um eine solche für pulver- bzw. rieselförmige Medien, insbesondere zur Anbindung an ein Lagerbehältnis wie einen Einwegcontainer 2, enthaltend: eine Förderwelle 3 zum Einführen in das Lagerbehältnis, wobei das von der Pump- und Mischvorrichtung abweisende Ende 3a der Förderwelle in das Lagerbehältnis kragend ist, ein zumindest einen Teil der Förderwelle umgebendes Gehäuse 4, welches eine Dosierkammer 6 aufweist bzw. umschließt und der Dosierkammer nachgeordnet eine Mischkammer 7, welche eine mit der Förderwelle 3 kraftübertragend verbundene Mischwelle 8 beherbergt sowie einen Wasseranschluss 9 zum Mischen des Mediums mit Wasser unter Bildung einer pastösen Masse enthält, sowie einen am Ende der Mischkammer 7 auf der der Vorlaufkammer 6 abgewandten Seite der Vorrichtung angebrachten gemeinsamen Antrieb für die Misch- und Förderwelle (in Fig. 9 dargestellt), sowie abschließend einen Ausgang 11 zum Anschluss einer Fördervorrichtung zum Weiterfördern der pastösen Masse oder zum Abfüllen in Eimer oder dergleichen.It is at the in Fig. 7a shown pumping and mixing device (there without drive) to such a powder or free-flowing media, in particular for connection to a storage container such as a disposable container 2, comprising: a conveyor shaft 3 for insertion into the storage container, wherein the pumping and Mixing device repellent end 3a of the conveyor shaft in the storage container is cantilevered, surrounding at least a portion of the conveyor shaft housing 4, which has a metering chamber 6 and the metering chamber downstream of a mixing chamber 7, which accommodates a power transmission with the conveyor shaft 3 connected mixing shaft 8 and a water connection 9 for mixing the medium with water to form a pasty mass, and a at the end of the mixing chamber 7 on the side facing away from the flow chamber 6 side of the device mounted common drive for the mixing and conveying shaft (in Fig. 9 shown), and finally an outlet 11 for connection of a conveying device for conveying the pasty mass or for filling into buckets or the like.

Im Gegensatz zu den oben gezeigten Ausführungsformen ist im Gehäuse 4 keine klassische "Vorlaufkammer" angeordnet. Stattdessen ist die Förderwelle 3 praktisch in Richtung zu dem Lagerbehältnis hin verschoben. Dies führt dazu, dass statt der im Gehäuse 4 ausgebildeten Vorlaufkammer ein "Vorlaufbereich" innerhalb des Einwegcontainers entsteht.In contrast to the embodiments shown above, no classic "flow chamber" is arranged in the housing 4. Instead, the conveyor shaft 3 is practically shifted in the direction of the storage container. As a result, instead of the flow chamber formed in the housing 4, a "flow area" is formed within the disposable container.

Dies ist besonders gut auch in Fig. 7b zu sehen. Dort ist gezeigt, wie die Dosierkammer 6 mit ihrem vorderen Ende das Gehäuse 4 bzw. den Schnellverschluss/Schraubverschluss die Pump- und Mischvorrichtung überragt bzw. aus dieser herauskragt. Dies führt dazu, dass nicht nur die Förderwelle 3 in das Lagerbehältnis bzw. den Einwegcontainer 2 hineinkragt, sondern auch das vordere Ende der Dosierkammer 6. Hierdurch kommt zu einer entsprechenden Querschnittsreduzierung bereits innerhalb des Containers, so dass dann keine zusätzliche Vorlaufkammer innerhalb des Gehäuses notwendig wird.This is especially good in too Fig. 7b to see. It shows how the metering chamber 6 with its front end projects beyond the housing 4 or the quick-action closure / screw-type closure over the pumping and mixing device or protrudes out of it. As a result, not only the conveyor shaft 3 protrudes into the storage container or the disposable container 2, but also the front end of the metering 6. This results in a corresponding cross-sectional reduction already within the container, so that then no additional flow chamber within the housing necessary becomes.

Fig. 7c zeigt eine (eher maßstabsgetreue) Zeichnung des Gegenstandes aus Fig. 7b. Fig. 7d hierzu einen entsprechenden seitlichen Schnitt. Fig. 7c shows a drawing (rather true to scale) of the object Fig. 7b , Fig. 7d For this purpose, a corresponding lateral section.

Im Übrigen sind den Fign. 7a und 7b die Mischwelle 8 zu entnehmen, welche an ihrem zur Dosierkammer hinweisenden Ende einen spiralförmigen Mischer hat und ansonsten an Streben 8a befestigt "hammerförmige" Querstreben zur besseren Durchmischung.Incidentally, the FIGS. 7a and 7b to take the mixing shaft 8, which at its end pointing to the dosing chamber has a spiral mixer and otherwise attached to struts 8a "hammer-shaped" cross struts for better mixing.
