Definitions
- the invention relates to a continuous mixing system which is used to mix powdered and/or granular solids with a liquid to form a slurry (mushy mass) and foam this slurry to form a mineral foam and pump it to the filling location.
- a slurry muscle mass
- the advantages of the continuous mixing system according to the invention are particularly valuable when the foamed slurry produced therewith is a self-curing mass, in particular a rapidly curing mass, for example a mineral formulation such as foamed concrete or a foamed mineral thermal insulation material.
- a problem when mixing powdered and/or granular solids with liquid to form a self-curing foamed slurry is that the slurry and the foam must be thoroughly mixed and transported gently to the filling point so that the foam structure is not destroyed.
- a further problem is that after the end of the discharge from the mixer, a residue of slurry remains as an adhesion in the mixer and hardens there if the mixer is not cleaned promptly.
- Typical continuous mixers for producing self-hardening slurry from powdered and/or granular solids and water have a conveyor device and a mixer, with the conveyor device continuously moving the solids through an opening into the chamber of the mixer, with liquid entering the chamber through at least one additional opening Chamber of the mixer is introduced, wherein the mixer mixes continuously and wherein the slurry formed continuously in the mixer flows out continuously through a further opening from the mixer.
- a conveyor device continuously moving the solids through an opening into the chamber of the mixer, with liquid entering the chamber through at least one additional opening Chamber of the mixer is introduced, wherein the mixer mixes continuously and wherein the slurry formed continuously in the mixer flows out continuously through a further opening from the mixer.
- DE19843777 (C1 ), EP0120812 (A2 ) and WO9615889 (A1 ) show devices for mixing a slurry.
- CN209755551 (U ), CN203449434 (U ) and CN201249476 (Y ) describe devices for producing and pumping foamed concrete from concrete.
- the DE 102019122041 (A1 ) describes a system for mixing a lightweight mixture of binding agent and bulk material and forcing the lightweight mixture to be conveyed using compressed air.
- the DE 3100443 A1 shows a continuous mixer for concrete or foam concrete, in which the solids via a screw conveyor from the bottom of a hopper into the chamber of a be transported horizontally arranged mixer. Mixing water is added in the front part of the mixer and the slurry is stirred. Foam is then added in the rear section of the mixer and mixed into the slurry.
- the DE 3629674 A1 and the WO2011044604 show similar continuous mixers, although the screw conveyor and mixer rotor do not have a common shaft and can be driven separately from one another. This allows the mixer to be emptied when only the screw conveyor and the other material feed are switched off. When cleaning the mixer, which usually takes place by spraying cleaning liquid into the mixing chamber, cleaning liquid can also get to the conveyed material located at the end area of the conveyor screw on the mixer side and form a self-hardening mass with it.
- the WO 2011106816 A1 shows a mixing plant for the production of a mineral foam, in which a free-flowing slurry is mixed in a first mixing section and mixed with foam in a second mixing section.
- both mixing sections are arranged horizontally and there is no eccentric screw pump.
- the EP 1065033 A2 shows a continuous mixer in which the powdered and/or granular solids are introduced from above into a vertical mixing chamber and not, as in the aforementioned documents, from one side into a horizontally arranged mixing chamber.
- An eccentric screw pump is connected to the lower end of the mixing chamber, which is used to transport the slurry to the place of use.
- the risk is somewhat reduced that liquid will reach powdered and/or granular solids that are not yet in the mixing chamber and form a hardenable mass with them. Due to the design, in particular due to the vertical orientation of the material flow through the mixing chamber and the directly subsequent conveyance by the pump without an intermediate container, the amount of slurry produced can be adjusted over a wide range and the amount of slurry in the system can be reduced.
- the DE 2437231 A1 shows a vertical mixer which has an eccentric screw pump at the lower end. Compressed air is added to the slurry in the middle of the preferably two-stage progressing cavity pump. On the outlet side, the progressing cavity pump is connected to a vortex chamber, in which a rapidly rotating tool further mixes the compressed air mixed with the slurry.
- the disadvantage is that the stirring tool is mounted vertically in the turbulence chamber and rotates quickly, so the mixing distance in the turbulence chamber is limited to the diameter of the stirring tool and the short, vigorous mixing can have a negative effect on the structure of the air pores.
- the DE 3807250 A1 shows a continuous mixer for mixing a slurry and a foam component.
- the mixer is fed with slurry via the hose line of a concrete pump, with the foam also being injected into the mixer.
- the disadvantage is that a premixed slurry is used, which is transported to and from the storage tank of a concrete pump a hose line to the mixer.
- the device shown is therefore useful for use on a construction site where a certain distance has to be overcome between the pump and the place of use. This device is unsuitable for the production of prefabricated components such as thermal insulation panels from rapidly hardening foamed slurry.
- the DE 4408088 A1 shows a method for the production of a porous mineral lightweight insulation board.
- a slurry is mixed in a first mixer, which enters an intermediate container and is transported away from there with a pump via a line.
- the line of the slurry and the line of the foam component are combined via a y-shaped branched mixing tube and homogenized by a static mixer.
- a static mixer has no rotating parts.
- the mixing takes place through static obstacles, which causes the components to swirl.
- the disadvantage is that the mixing in the static mixer cannot be adapted to a variable flow rate.
- the cleaning of the static mixer turns out to be difficult, since it is not possible to discharge material from the static mixer when the pump is at a standstill.
- a rapidly hardening mass tends to cake on the complex-shaped obstacles in the static mixer, with areas located behind the obstacles being difficult to clean even with water that is pumped through the static mixer under pressure.
- the EP3145687B 1 (also published as WO2015176092A2 ) of the applicant shows a continuous mixing system comprising a vertical mixer and a horizontal mixer, which continuous mixing system is designed to enable thorough mixing of the slurry and the foam and to prevent or reduce the adhesion of hardening material in the system.

Description
Die Erfindung betrifft eine Durchlaufmischanlage, welche dazu dient pulverförmige und/oder körnige Feststoffe mit einer Flüssigkeit zu einem Slurry (breiige Masse) zu vermischen und diesen Slurry zu einem Mineralschaum aufzuschäumen und an den Abfüllort zu pumpen.The invention relates to a continuous mixing system which is used to mix powdered and/or granular solids with a liquid to form a slurry (mushy mass) and foam this slurry to form a mineral foam and pump it to the filling location.
Die Vorteile der erfindungsgemäßen Durchlaufmischanlage sind vor allem dann wertvoll, wenn der damit hergestellte, geschäumte Slurry eine selbstaushärtende Masse, insbesondere eine rasch aushärtende Masse, beispielsweise eine mineralische Formulierung, wie Schaumbeton oder eine geschäumter mineralischer Wärmedämmstoff, ist.The advantages of the continuous mixing system according to the invention are particularly valuable when the foamed slurry produced therewith is a self-curing mass, in particular a rapidly curing mass, for example a mineral formulation such as foamed concrete or a foamed mineral thermal insulation material.
Ein Problem beim Mischen von pulverförmigen und/oder körnigen Feststoffen mit Flüssigkeit zu einem selbstaushärtenden geschäumten Slurry besteht darin, dass eine gute Durchmischung des Slurry und des Schaums und ein schonender Transport bis zum Abfüllort erfolgen muss, sodass die Schaumstruktur nicht zerstört wird.A problem when mixing powdered and/or granular solids with liquid to form a self-curing foamed slurry is that the slurry and the foam must be thoroughly mixed and transported gently to the filling point so that the foam structure is not destroyed.
Ein weiteres Problem ist, dass nach Beendigung des Austrags aus dem Mischer ein Rest von Slurry als Anhaftung im Mischer verbleibt und dort aushärtet, sofern der Mischer nicht zeitnah gereinigt wird. Indem man einen Durchlaufmischer verwendet, mit Hilfe dessen man über einen längeren Zeitraum im Durchlauf mischen kann - und nicht in einzelnen getrennten Chargen mit dazwischen liegenden Stillstandszeiten mischen muss, - wird zwar der Reinigungsaufwand verringert, jedoch muss auch hier nach erfolgtem Austrag oder bei einem außerplanmäßigen Stopp des Mischers eine Reinigung erfolgen.A further problem is that after the end of the discharge from the mixer, a residue of slurry remains as an adhesion in the mixer and hardens there if the mixer is not cleaned promptly. By using a continuous mixer, with the help of which one can mix continuously over a longer period of time - and does not have to mix in individual separate batches with intermediate downtimes - the cleaning effort is reduced, but here too after the discharge has taken place or in the event of an unscheduled discharge stop the mixer cleaning must be carried out.

Es existieren viele nach dem Stand der Technik bekannte Methoden und Vorrichtungen um dem Slurry eine Schaumkomponente oder Druckluft zuzusetzen, um einen geschäumtes bzw. luftporen- aufweisendes Baumaterial zu erhalten.Typical continuous mixers for producing self-hardening slurry from powdered and/or granular solids and water have a conveyor device and a mixer, with the conveyor device continuously moving the solids through an opening into the chamber of the mixer, with liquid entering the chamber through at least one additional opening Chamber of the mixer is introduced, wherein the mixer mixes continuously and wherein the slurry formed continuously in the mixer flows out continuously through a further opening from the mixer. There are many methods and devices known from the prior art for adding a foam component or compressed air to the slurry in order to obtain a foamed or air-pored building material.

Das Abstreifrohr wird verwendet um einen Übergang zwischen Mischrohr und dem Behälter für den geschäumten Slurry, insbesondere in Form eines Pumpentrichters zu ermöglichen. Das Abstreifrohr weist bevorzugt einen außenliegenden Zahnkranz auf, welcher mit einem Elektromotor angetrieben wird. Zudem umfasst das Abstreifrohr - bevorzugt auf der Oberseite - ein innenliegendes Abstreifelement, bevorzugt in Form einer Gummilippe. Durch Rotation des Abstreifrohrs um die eigene Achse wird die Innenseite kontinuierlich vom Abstreifelement abgestreift und somit werden Anpackungen im Abstreifrohr vermieden. Abgestreiftes Material fällt herab auf den im unteren Bereich des Abstreifrohres bewegten Mineralschaum und wird mit diesem weitertransportiert bis zum Eingang der Förderpumpe.The scraper tube is used to allow a transition between the mixing tube and the container for the foamed slurry, in particular in the form of a pump funnel. The scraper tube preferably has an external ring gear which is driven by an electric motor. In addition, the scraper tube includes--preferably on the upper side--an internal scraper element, preferably in the form of a rubber lip. By rotating the scraper tube around its own axis, the inside is continuously scraped off by the scraper element, thus avoiding packing in the scraper tube. Scraped material falls down onto the mineral foam moving in the lower area of the scraper tube and is transported with it to the inlet of the feed pump.
Bevorzugt umfasst die Anlage eine Schaumzerstörungslanze, welche verwendet wird, um das AbfallVolumen des Mineralschaums zu reduzieren. Erzielt wird diese Zerstörung der Schaumporen durch eine oder mehrere Luftdüsen, welche in einem Rohrabschnitt radial umlaufend und hin zur Rohrmitte gerichtet, montiert werden.Preferably, the plant comprises a froth destruction lance which is used to reduce the waste volume of the mineral froth. This destruction of the foam pores is achieved by one or more air nozzles, which are mounted radially around a pipe section and directed towards the center of the pipe.
Diese Schaumzerstörungslanze ist entweder am Ende einer eigenen Schlauchleitung montiert, oder sie wird als Zerstörungsstation an einem zusätzlichen Abfallcontainer ausgeführt, in welche die Fülllanze gesteckt wird.This foam destruction lance is either installed at the end of a separate hose line or it is designed as a destruction station on an additional waste container into which the filling lance is inserted.
In einer anderen Ausführungsvariante wird eine Zerstörung des Schaums durch mechanische Elemente erreicht, bevorzugt durch rotierende mechanische Elemente, beispielsweise durch eine Impellerpumpe.In another embodiment variant, the foam is destroyed by mechanical elements, preferably by rotating mechanical elements, for example by an impeller pump.
Bevorzugt umfasst die Anlage eine Umschaltventil, insbesondere in Form eines 2-Wegeventils. Dieses Ventil wird verwendet, um es bei Verwendung von nur einer Pumpe zu ermöglichen, den Mineralschaum einerseits durch die Produktionsschlauchleitung zur Abfüllung zu bewegen und andererseits den Mineralschaum im Pausenbetrieb der Anlage durch die Zerstörungsschlauchleitung zu fördern.The system preferably includes a switching valve, in particular in the form of a 2-way valve. This valve is used to make it possible, when using only one pump, to move the mineral foam through the production hose line to filling on the one hand and to convey the mineral foam through the destruction hose line on the other hand when the system is paused.
Das Ventil besteht bevorzugt aus zwei Kunststoffplatten welche durch eine Achse miteinander verbunden sind. Die ausgangsseitige Platte ist fix mit dem Container oder dem Tragegestell verschraubt und mit zwei Schlauchtüllen (Produktions- und Zerstörungsschlauchleitung) ausgestattet.The valve preferably consists of two plastic plates which are connected to one another by an axle. The plate on the outlet side is bolted to the container or the carrying frame and is equipped with two hose nozzles (production and destruction hose lines).
Die Eingangsseite ist mit einer Schlauchtülle, sowie einem Zahnkranz versehen. Der Zahnkranz wird benötigt, um durch einen Antrieb eine Drehung der Schlauchtülle zu ermöglichen, um die eingangsseitige Schlauchtülle entweder mit der Produktionsleitung oder der Zerstörungsleitung zu verbinden. Bevorzugt ist auf der eingangsseitigen Kunststoffplatte eine Wasserdüse montiert, welche dazu verwendet wird, die Zerstörungsleitung zu spülen, wenn diese nicht in Verwendung ist.The input side is provided with a hose nozzle and a sprocket. The toothed ring is required to enable rotation of the hose nozzle by a drive in order to connect the hose nozzle on the inlet side to either the production line or the destruction line. Preferably, a water jet is mounted on the upstream plastic panel and is used to flush the blowout line when not in use.
Die Produktionsleitung ist bevorzugt zumindest in einem Abschnitt als Schlauchleitung ausgeführt und führt zu einer Abfüllvorrichtung.The production line is preferably designed as a hose line, at least in one section, and leads to a filling device.
Bevorzugt erfolgt das Abfüllen in eine Betonschale zur Herstellung von wärmegedämmten Fertigbauelementen.The filling preferably takes place in a concrete shell for the production of thermally insulated prefabricated building elements.
Bevorzugt umfasst die Abfüllvorrichtung eine Abziehbrücke. Während des Auftragens des Mineralschaums auf die Betonschale wird der Schaum direkt mit einem Abziehelement, insbesondere einem Kunststoffbesen, glattgestrichen und nivelliert. Das Abziehelement ist über eine drehbare Achse an einer Brücke angebracht und kann bevorzugt mittels Funksignal gedreht werden.The filling device preferably comprises a pull-off bridge. During the application of the mineral foam to the concrete shell, the foam is smoothed and leveled directly with a squeegee, in particular a plastic broom. The pull-off element is attached to a bridge via a rotatable axis and can preferably be rotated by means of a radio signal.
Die Achse ist an einer "Laufkatze" montiert, um die gesamte Länge der Brücke bedienen zu können.The axle is mounted on a "trolley" to service the full length of the bridge.
Je nach benötigter Dämmstärke kann die Höhe des Abziehelements in Bezug auf die Betonschale eingestellt und fixiert werden.Depending on the insulation thickness required, the height of the pull-off element can be adjusted and fixed in relation to the concrete shell.
Die Brücke selbst läuft bevorzugt auf Schienen auf dem Tisch bzw. kann, je nach Bedarf, auch über ein Wand- oder Deckensystem laufen. Eine Seite kann dabei auf Schienen geführt werden, die zweite Seite kann mit freilaufenden Rollen ausgeführt sein.The bridge itself preferably runs on rails on the table or, depending on requirements, can also run over a wall or ceiling system. One side can be guided on rails, the second side can be designed with free-running rollers.

In beiden Strängen kann bevorzugt die Temperatur des Wassers unabhängig zueinander eingestellt werden. Bevorzugt wird die Temperatur des Wassers durch eine Vorrichtung oder Steuerungsanlage gesteuert oder geregelt, insbesondere elektronisch. In beiden Strängen sind bevorzugt Druckregelventile angeordnet, zur Regelung des Drucks unter welchem das Anmachwasser eingebracht wird und zur Regelung des Drucks unter welchem das Wasser in den Schaumkanonen eingebracht wird.The water supply from a source is preferably divided into two strands for the water treatment for the mineral foam mixing plant. It is divided into a line for the mixing water for the slurry and a line for the water used to generate the foam. The amount of water in both strands can preferably be set independently of one another.

In both strands, the temperature of the water can preferably be set independently of one another. The temperature of the water is preferably controlled or regulated by a device or control system, in particular electronically. Pressure control valves are preferably arranged in both lines to control the pressure under which the mixing water is introduced and to control the pressure under which the water is introduced into the foam guns.
Bevorzugt werden die Motoren der Vorrichtung, insbesondere jene welche am Prozess der Mineralschaumerzeugung und Förderung beteiligt sind, von einer Steuerungseinheit überwacht, sodass erkannt wird, sollte einer der Motoren ausfallen.The motors of the device, in particular those involved in the process of producing and conveying mineral foam, are preferably monitored by a control unit so that it is recognized if one of the motors should fail.

Wie in
Die innenliegende Mantelfläche des Schaummischers 2 ist durch ein Kunststoffrohr gebildet. Um die im Schaummischer 2 auftretenden Kräfte und Momente aufzunehmen bzw. zu übertragen ist das Kunststoffrohr in einem bevorzugt dreigeteilten Gehäuse aufgenommen. Das Gehäuse hat einen vorderen Abschnitt, welcher eine Öffnung für den Slurryeinlass, ein Lager für das horizontale Mischwerkzeug und eine Öffnung für die Schaumzufuhr aufweist. Das Gehäuse hat einen hinteren Abschnitt, welcher ein Lager für das horizontale Mischwerkzeug aufweist. Um Kräfte und Drehmomente zwischen den beiden beschriebenen Abschnitten zu übertragen, weist das Gehäuse einen mittleren Abschnitt auf, welcher die beiden Abschnitte, bevorzugt lösbar, verbindet. Der Abschnitt ist bevorzugt durch ein Gestänge, beispielsweise drei über den Umfang des Kunststoffrohrs verteilte Stangen gebildet. Der Abschnitt kann bevorzugt eine wannenförmige Auflage für das Kunststoffrohr aufweisen, um selbst ein leichtes Durchhängen dessen zu verhindern. Am hinteren Abschnitt schließt bei der

Im Transportcontainer 5 ist ein Traggestell 7 angeordnet, welches sich über die gesamte Höhe des Transportcontainers 5 erstreckt. Das Traggestell 7 weist bevorzugt vier Steher auf, welche an den Ecken eines gedachten Rechtecks vorliegen. Die Steher sind im unteren Bereich und im oberen Bereich jeweils durch Querbalken verbunden. Unterhalb des Containerbodens können in einer Ausführungsvariante Standfüße 6 vorliegen, welche von unten in die Steher eingesetzt sind. Bevorzugt sind die Standfüße 6 höhenverstellbar. Die Standfüße 6 können insbesondere in eine Gewindeplatte eingeschraubt werden. Zudem können weitere Standfüße unterhalb der Ecken des Containers angebracht werden, oder die Ecken des Containers durch Unterlage von Balken oder Keilen abgestützt werden, um den Containerboden zu entlasten.A
In einer alternativen Ausführungsvariante stehen die Standfüße 6 des Traggestell 7 am Containerboden und sind bevorzugt mit diesem verschraubt, wobei der Containerboden zumindest im Bereich unterhalb der Standfüße 6 verstärkt ausgeführt ist. Dazu können Stahlprofile am Containerboden verschweißt werden.In an alternative embodiment, the
Bevorzugt ist die Containerwand mit vertikalen Streben verstärkt, insbesondere beidseitig neben dem Bedienelement 17.The container wall is preferably reinforced with vertical struts, in particular on both sides next to the
Der Container kann auf Rollen gestellt werden und mit einem Zugwerkzeug auf bekannte Weise verschoben werden.The container can be placed on rollers and moved in a known manner using a pulling tool.
Im Containerboden sind bevorzugt Hohlprofile vorgesehen, welche an der Längsseite des Containers offen sind, um diesen mit einem Gabelstapler heben zu können. Bevorzugt wird der Container modifiziert, sodass der Abstand der Hohlprofile schmäler ausgeführt ist, als bei einem Standardcontainer.Hollow profiles are preferably provided in the container floor, which are open on the longitudinal side of the container in order to be able to lift it with a forklift. The container is preferably modified so that the distance between the hollow profiles is narrower than in a standard container.
Die oberen Enden der Steher können das Containerdach überragen. Alternativ können die oberen Enden der Steher auch bündig mit dem Containerdach oder darunter angeordnet sein und durch Öffnungen oder eine große gemeinsame Öffnung im Containerdach zugänglich gemacht werden.The upper ends of the uprights can protrude beyond the container roof. Alternatively, the upper ends of the uprights may be flush with or below the container roof and made accessible through openings or a large common opening in the container roof.
Bevorzugt ist das Containerdach zur Gänze entfernt, sodass Wärme aus dem Inneren des Containers besser entweichen kann. Anstelle des Containerdaches können Querstreben eingesetzt werden, welche die Seitenwände verbinden.The container roof is preferably removed completely, so that heat from the interior of the container can escape better. Instead of the container roof, cross braces can be used to connect the side walls.
Beim Transport des Containers wird die Öffnung im Dach bzw. die offene obere Seite des Containers bevorzugt mit einer Plane verschlossen.When transporting the container, the opening in the roof or the open upper side of the container is preferably closed with a tarpaulin.
Bevorzugt ist zumindest an einer Breitseite des Containers eine Gittertür eingesetzt. Bevorzugt sind an beiden Breitseiten des Containers Gittertüren eingesetzt.A lattice door is preferably used at least on one broad side of the container. Mesh doors are preferably used on both broad sides of the container.
Bevorzugt weist die jeweilige Gittertür einen Kontaktgeber oder Sensor auf. Bevorzugt können die Gittertüren nur während des Stillstands der Anlagenkomponenten geöffnet werden.The respective lattice door preferably has a contactor or sensor. The lattice doors can preferably only be opened while the system components are at a standstill.
Bevorzugt weist die Anlage einen Antrieb auf, beispielsweise in Form eines Hubzylinders, über welchen eine Entkopplung des Slurrymischers und des Schaummischers erfolgt, wobei dieser Antrieb nur bei geöffneter Gittertür betätigbar ist, um die beiden Mischer für die Reinigung der Mischwerkzeuge trennen zu können.The system preferably has a drive, for example in the form of a lifting cylinder, via which the slurry mixer and the foam mixer are decoupled. This drive can only be actuated when the lattice door is open, in order to be able to separate the two mixers for cleaning the mixing tools.
Die Motoren der beiden Mischer sind bevorzugt schwenkbar gelagert, wobei diese beim Wegschwenken von den Mischwerkzeugen entkoppelt werden. Bevorzugt erfolgt das Verschwenken zumindest eines der Motoren, insbesondere jenes des Slurrymischers, mit einem Antrieb, beispielsweise in Form eines Hubzylinders, wobei dieser Antrieb nur bei geöffneter Gittertür betätigbar ist, um den Motor für die Reinigung der Mischwerkzeuge von diesen trennen zu können.The motors of the two mixers are preferably pivotably mounted, with these being decoupled from the mixing tools when they are pivoted away. Preferably, at least one of the motors, in particular that of the slurry mixer, is pivoted with a drive, for example in the form of a lifting cylinder, this drive being operable only when the lattice door is open in order to be able to separate the motor for cleaning the mixing tools.
In einer Ausführungsvariante weist zumindest einer der beiden Mischer, insbesondere der Slurrymischer, einen Sensor zur Erkennung der Lage des Kopplungsstücks der Mischwerkzeugwelle auf. Bevorzugt ist der Motor des jeweiligen Mischers ein Servomotor. Bevorzugt wird der abgekoppelte Motor in Abhängigkeit der Lage des Kopplungsstücks angesteuert, sodass dessen Welle in Abhängigkeit der Lage des Kopplungsstücks ausgerichtet wird. Beim Bewegen, insbesondere Schwenken, des Servomotors hin zum Mischwerkzeug erfolgt aufgrund der erfolgten Lageerkennung des Mischwerkzeugs und der Ausrichtung der Welle des Motors eine automatische Kopplung von Motorwelle und Mischwerkzeugwelle.In one embodiment variant, at least one of the two mixers, in particular the slurry mixer, has a sensor for detecting the position of the coupling piece of the mixing tool shaft. The motor of the respective mixer is preferably a servo motor. The decoupled motor is preferably controlled depending on the position of the coupling piece, so that its shaft is aligned depending on the position of the coupling piece. When the servo motor is moved, in particular pivoted, towards the mixing tool, the motor shaft and the mixing tool shaft are automatically coupled due to the position detection of the mixing tool and the alignment of the motor shaft.
In einer anderen Ausführungsvariante liegt die Welle des abgekoppelten Motors mit einer bekannten Ausrichtung vor und das Mischwerkzeug wird entsprechend dieser Ausrichtung ausgerichtet, bevor der Motor in Richtung des Mischers bewegt, insbesondere geschwenkt wird. Um dies zu erreichen, kann der Motor beim Abschalten immer in derselben Stellung bzw. Ausrichtung seiner Welle gestoppt werden. Die Ausrichtung des Mischwerkzeugs (welches beispielsweise entnommen, gereinigt und wiedereingesetzt wurde) kann manuell vorgenommen werden, bevor der Motor hin zum Mischwerkzeug bewegt wird, insbesondere geschwenkt wird. Dadurch wird eine automatische Kopplung der Welle des Motors mit dem Mischwerkzeugwelle erreicht.In another embodiment, the shaft of the decoupled motor is in a known orientation and the mixing tool is aligned in accordance with this orientation before the motor is moved, in particular pivoted, in the direction of the mixer. In order to achieve this, the motor can always be stopped in the same position or orientation of its shaft when it is switched off. The alignment of the mixing tool (which, for example, has been removed, cleaned and reinserted) can be carried out manually before the motor is moved towards the mixing tool, in particular pivoted. This achieves an automatic coupling of the shaft of the motor with the shaft of the mixing tool.

Sofern Schüttgutbehälter verwendet werden, welche am unteren Ende nicht mit eine verschnürten oder anders verschlossenen und öffenbaren Öffnung ausgestattet sind, ist bevorzugt eine Vorrichtung zum Aufschneiden des Schüttgutbehälters im Trichter 10 angeordnet, insbesondere eine Messerpyramide, wie in
Am oberen Ende der Halterungsvorrichtung 8 können wie dargestellt rechteckige Hohlprofile angeordnet sein, um die Halterungsvorrichtung 8 mithilfe eines Gabelstaplers auf das Traggestell 7 heben zu können. Alternativ kann die Halterungsvorrichtung 8 auch mit einem Kran vom Traggestell 7 abgehoben werden. Bevorzugt erfolgt das Platzieren eines Bigbags indem die Halterungsvorrichtung 8 vom Traggestell 7 abgehoben wird und über einem am Boden, oder einem Podest abgestellten Bigbag platziert wird. Nachdem der Bigbag an der Halterungsvorrichtung 8 befestigt wurde, wird diese wieder auf das Traggestell 7 gehoben. In einer anderen Ausführungsvariante besteht die Halterungsvorrichtung 8 aus zwei Teilen, wobei nur das obere Teil, umfassend die Hohlprofile und die Befestigungsmittel für den flexiblen Schüttgutbehälter abgehoben werden. Bevorzugt liegen die Hohlprofile und die Befestigungsmittel an einem gemeinsamen Rahmenelement vor. Das obere Teil oder das untere Teil weist bevorzugt vier Zentrierkegel auf, wobei das jeweilige andere Element vier korrespondierende Öffnungen aufweist. Dadurch wird das exakte Platzieren des oberen Teils am unteren Teil erleichtert.As shown, rectangular hollow profiles can be arranged at the upper end of the mounting

foam mixer 2. - elements with an orientation at an angle to the conveying direction, the inclination being in the direction of rotation of the mixing tool,
- Elements with an alignment oblique to the conveying direction, the oblique position being opposite to the direction of rotation of the mixing tool.
Es wird angenommen, dass die Elemente mit einer Schrägstellung in Drehrichtung des Mischwerkzeugs einen beschleunigten Transport des Schaumes bewirken, während die Elemente mit einer Schrägstellung gegen die Drehrichtung des Mischwerkzeugs einen verlangsamten Transport des Schaumes bewirken.

Bevorzugt ist der eingangsseitige Anschluss 23 an einem schwenkbaren Element befestigt, um wahlweise mit einem der beiden Ausgänge 15 und 16 des Umschaltelements 14 verbunden werden zu können. Das Verschwenken des eingangsseitigen Anschlusses 23 erfolgt bevorzugt mit einem Antrieb, beispielsweise mittels eines Zahnkranzes, welcher mittels eines Motors gedreht wird. Weniger bevorzugt könnten auch die beiden Ausgänge 15 und 16 an einem schwenkbaren oder verschiebbaren Element befestigt sein, um wechselweise mit dem eingangsseitigen Anschluss 23 verbunden werden zu können. Weniger bevorzugt kann der eingangsseitige Anschluss 23 auch an einem verschiebbaren Element befestigt sein.The
An einem der beiden Ausgänge 15 und 16 ist eine Leitung zum Abfüllungsort des Mineralschaums angeschlossen. An dem anderen Ausgang 15 oder 16 ist eine Leitung zu einem Abfallbehälter angeschlossen. Am Abfüllungsort, beispielsweise an einer von Hand geführten Abfülllanze, befindet sich bevorzugt ein Schalter oder ein Taster oder ein anderes geeignetes Bedienelement, wie ein Hebel, über welches das Abfüllen gestoppt oder gestartet werden kann. Das Bedienelement für das Abfüllen kann auf einem transportablen Gerät vorliegen. Das Bedienelement 17 kann ein Bedienelement oder eine Bedienfunktion für den Start und den Stopp der Schaumförderung am Abfüllort aufweisen.At one of the two

Bevorzugt befindet sich zwischen dem Umschaltelement 14 und dem Abfallbehälter eine Schaumzerstörungsvorrichtung, welche die Luftbläschen des zum Abfallbehälter transportierten Schaumes zerstört, um das Abfallvolumen zu verringern.A foam destruction device is preferably located between the switching
Als Schaumzerstörungsvorrichtung hat sich eine Impellerpumpe als geeignet erwiesen.An impeller pump has proven to be suitable as a foam destruction device.
Bevorzugt wird der Schaum in einen Behälter an der Eingangsseite der Impellerpumpe gefördert, wobei in den Behälter auch ein Wassereinlass mündet. Der Wassereinlass ist bevorzugt auf den Schaumeinlass des Behälters ausgerichtet, sodass das einströmende Wasser, insbesondere in Form eines Strahls auf den in den Behälter eintretenden Schaum trifft. Der Behälter ist bevorzugt durch einen abnehmbaren Deckel verschlossen.The foam is preferably conveyed into a container on the inlet side of the impeller pump, with a water inlet also opening into the container. The water inlet is preferably aligned with the foam inlet of the container, so that the inflowing water, in particular in the form of a jet, impinges on the foam entering the container. The container is preferably closed by a removable lid.
Bevorzugt kann das Umschaltelement 14 einen Wasseranschluss aufweisen, um die Leitung zum Abfallbehälter zu spülen, nachdem diese in Verwendung war.

Das bezüglich Menge und Temperatur eingestellte Wasser einer zweiten Mischbatterie 28 wird mindestens einer Vorrichtung zur Erzeugung von Schaum, beispielsweise einer Schaumkanone 29 zugeführt. Beispielsweise wird ein Tensid- oder Proteinschaum hergestellt. Wie dargestellt, sind bevorzugt zumindest zwei Vorrichtungen zur Erzeugung von Schaum, beispielsweise zwei Schaumkanonen 29 vorhanden. Diese können wie dargestellt von einer gemeinsamen Mischbatterie 28 gespeist werden. In einer anderen Ausführungsvariante kann je Schaumkanone 29 eine Mischbatterie 28 vorhanden sein, sodass auch die Menge und Temperatur des Wassers der Schaumkanonen 29 unabhängig voneinander einstellbar, steuerbar oder regelbar ist. Wie dargestellt, münden die Schaumleitungen der Schaumkanonen 29 jeweils an unabhängigen Positionen am vorderen Ende des Schaummischers 2 in diesen. Bevorzugt befindet sich der erste Schaumeinlass seitlich am Mischergehäuse in jenem Längsbereich, in dem am oberen Ende die Exzenterpumpe 4 vorliegt.

In einer anderen Ausführungsvariante befindet sich zumindest ein Schaumeinlass in Transportrichtung des Schaummischers gesehen vor dem Einlass für den Slurry. Vorteilhaft wird der Schaummischer so zunächst mit Schaum gefüllt und der Slurry wird dem Schaum in einem dahinterliegenden Abschnitt beigemischt. Dadurch wird verhindert bzw. vermindert, dass Slurry, und somit aushärtendes Material, an das motorseitige Ende des Mischergehäuses gelangt. Bevorzugt münden beide Schaumeinlässe vor dem Einlass für den Slurry in den Innenraum des Schaummischers.In another embodiment variant, at least one foam inlet is located in front of the inlet for the slurry, viewed in the transport direction of the foam mixer. In this way, the foam mixer is advantageously first filled with foam and the slurry is admixed with the foam in a section located behind it. This prevents or reduces slurry, and thus hardening material, from reaching the end of the mixer housing on the motor side. Both foam inlets preferably open into the interior of the foam mixer before the inlet for the slurry.
In einer Ausführungsvariante ist das Umschaltelement 14 nicht vorhanden und am Abfüllort wird die Produktionsleitung in einen Abfallcontainer bzw. eine Schaumzerstörungsvorrichtung platziert, wenn die Abfüllung in die zu füllenden Bauteile kurzzeitig unterbrochen wird.In one embodiment, the switching
In jener Ausführungsvariante mit Umschaltelement 14 ist bevorzugt vorgesehen, dass dieses nach einer vorgebbaren Zeitdauer (in Abhängigkeit der Aushärtezeit) automatisch von der Zerstörungsleitung zurück auf die Produktionsleitung umschaltet, da ansonsten das Material in der Produktionsleitung aushärten würde. Bevorzugt wird das Umschalten mittels eines Alarms angekündigt. Der Transport von Schaum durch die Zerstörungsleitung-erfolgt bevorzugt nur in Pausen, beispielsweise beim Wechsel von einem zu füllenden Element zum nächsten. Der Transport durch die Zerstörungsleitung kann in einer Ausführungsvariante nur solange erfolgen, bis der Bediener die Produktionsleitung in einem Abfallcontainer oder einer Schaumzerstörungsvorrichtung platziert hat.In that embodiment variant with
In einer alternativen Ausführungsvariante kann nach einer vorgebbaren Zeitdauer ein Spülen der Produktionsleitung erfolgen. In einer alternativen Ausführungsvariante kann nach einer vorgebbaren Zeitdauer ein Stopp und Spülen der gesamten Anlage erfolgen.In an alternative embodiment variant, the production line can be flushed after a predefinable period of time. In an alternative embodiment variant, the entire system can be stopped and flushed after a predefinable period of time.
Bevorzugt kann der Bediener zwischen dem Pausenmodus mit Schaumzerstörung und einen Anlagenstopp mit Stopp der Materialzufuhr und Spülen der Anlage mit Reinigungsflüssigkeit, insbesondere Wasser, wählen.The operator can preferably choose between the pause mode with foam destruction and a system stop with stopping of the material supply and rinsing of the system with cleaning liquid, in particular water.
