The invention has for its object a silo container of the aforementioned To improve the genus so that it is as easy to use as possible The most homogeneous building material possible can.

Diese Aufgabe wird erfindungsgemäß mit einem gattungsgemäßen Silobehälter gelöst, der dadurch gekennzeichnet ist, dass die Dosiervorrichtung mit veränderbarem Volumenstrom regelbar ausgebildet ist.This object is achieved according to the invention with a generic silo container, which is characterized in that the Dosing device with variable volume flow is designed to be controllable.

Aus den Kammern wird über die Dosiervorrichtung ein gewünschter Volumenstrom geregelt und dem Mischtrichter zugeführt, in welchem die Komponenten bereits miteinander vermischt werden. Nach dieser Vormischung in dem Mischtrichter wird das Gemisch dem Zwangsmischer zugeführt, in welchem das Gemisch neuerlich gemischt und gegebenenfalls verpresst wird. So entsteht ein sehr homogener Baustoff mit mehreren Komponenten.A desired volume flow is made from the chambers via the metering device regulated and fed to the mixing hopper, in which the components are already together be mixed. After this premixing in the mixing funnel, this becomes Mixture fed to the compulsory mixer, in which the mixture was mixed again and optionally pressed. This creates a very homogeneous building material with several Components.

Vorteilhafte Weiterbildungen aus Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen genannt. Advantageous developments from embodiments of the invention are in the dependent Called claims.

Günstigerweise kann der Verbindungskanal die andere Kammer freistehend durchqueren. Durch die freistehende Anordnung kann der Verbindungskanal einfach an der einen Kammer und der Dosiervorrichtung angebracht werden. Im Durchquerungsbereich ist der Verbindungskanal frei von einer Verbindung mit der anderen Kammer. Er kann lediglich an einer Durchstrittsstelle durch eine Wandung der anderen Kammer an dieser befestigt sein.Conveniently, the connecting channel can cross the other chamber free-standing. Due to the free-standing arrangement, the connecting channel can be easily attached to one Chamber and the dosing device are attached. In the traversing area the connection channel is free of connection with the other chamber. He can only at a point of passage through a wall of the other chamber on it be attached.

Möglicherweise kann der Verbindungskanal unmittelbar an der Wand des Silobehälters anliegen.Possibly the connection channel can be directly on the wall of the silo container issue.

Als Variante der Erfindung erstrecken sich beide Kammern im wesentlichen über den gesamten Querschnitt des Silobehälters. Dadurch kann beim Befüllen der gesamte Querschnitt des Silobehälters als Fülltiefe benutzt werden, was zu einer guten Befüllung der Kammer führt.As a variant of the invention, both chambers extend essentially over the entire cross section of the silo container. This means that the entire Cross section of the silo container can be used as filling depth, which leads to a good filling the chamber leads.

Wahlweise hat der Silobehälter eine etwa kreiszylindrische Form. Diese Form eignet sich besonders gut für die erfindungsgemäße sequentielle Anordnung der Kammern mit dem Verbindungskanal. Optionally, the silo container has an approximately circular cylindrical shape. This form is suitable particularly good for the sequential arrangement of the chambers according to the invention with the Connecting channel.

Günstigerweise kann mindestens eine Kammer mindestens zwei Füllöffnungen aufweisen, die in Längsrichtung des Silobehälters gesehen beabstandet voneinander angeordnet sind. Damit können besonders günstig Trockenstoffe in die Kammern eingefüllt werden. Durch die beabstandete Anordnung der Einfüllöffnungen kann der Trockenstoff an unterschiedlichen Orten in die Kammer eingebracht werden, so daß die Kammer besser befüllbar ist und entstehende Baustoffaufschüttungen bzw. -berge in der Kammer beim Befüllen der Kammer nicht stören.Conveniently, at least one chamber can have at least two filling openings, seen in the longitudinal direction of the silo container spaced apart are. This means that dry substances can be filled into the chambers particularly cheaply become. Due to the spaced arrangement of the filling openings, the dry substance be introduced into the chamber at different locations so that the chamber is easier to fill and build-up material or mountains in the chamber do not disturb when filling the chamber.

Denkbar kann der Abstand der Einfüllöffnungen einer Kammer etwa der Hälfte bis ein Drittel der Länge dieser Kammer entsprechen. Dieser Abstand gewährleistet eine besonders gute und vollständige Befüllung der Kammer.The distance between the filling openings of a chamber can be about half to one Correspond to one third of the length of this chamber. This distance ensures a special good and complete filling of the chamber.

In besonderer Weise können die Einfüllöffnungen der Kammern in Längsrichtung des Silobehälters etwa auf derselben Längslinie vorgesehen sein. Dies ist günstig wenn der Silobehälter von einer Seite befüllt werden soll. Dann können die Einfüllöffnungen wie bei großen, auf LKW vorgesehenen Silobehältem über Einfüllöffnungen an der Oberseite des liegenden Behälters nacheinander befüllt werden.In a special way, the filling openings of the chambers in the longitudinal direction of the Silo container can be provided approximately on the same longitudinal line. This is convenient if the Silo container to be filled from one side. Then the filler openings can be as in large silo containers intended for trucks via filling openings on the top of the lying container are filled one after the other.

Vorzugsweise kann die Dosiervorrichtung als Zellradförderer ausgebildet sein. Mit Hilfe eines Zellrades kann die jeweilige Komponente in gewünschter Menge aus der Kammer entnommen werden.

Die gewünschte Menge kann beispielsweise durch Steuerung der Drehzahl des Zellrades bemessen werden.The metering device can preferably be designed as a cellular wheel conveyor. With help A cell wheel can remove the respective component from the chamber in the desired amount be removed. The cells of the cellular wheel enable a dosed removal of the Component from the respective chamber. For example, the desired amount can be measured by controlling the speed of the cellular wheel.

Besonders vorteilhaft kann die Dosiervorrichtung für jede Kammer ein eigenes Dosiermittel aufweisen. Dies ermöglicht eine besonders gute Steuerung der einzelnen Komponenten. So kann z.B. an jeder Kammer ein eigenes Dosiermittel in Form des vorgenannten Zellrades vorgesehen sein. Dadurch lassen sich verschiedene Mischungsverhältnisse einstellen.The metering device can have a separate metering agent for each chamber exhibit. This enables particularly good control of the individual components. For example, each chamber has its own dosing agent in the form of the aforementioned Cell wheel can be provided. This allows different mixing ratios to adjust.

Günstigerweise kann von außen ein separater Zufuhrkanal in die Mischeinrichtung münden. Damit lassen sich vor Ort Zusatzstoffe zu dem Baustoff geben. Beispielsweise kann Wasser zugemischt werden, so daß in dem Silobehälter nur Trockenstoffe gelagert werden. Damit wird das relativ schwere Wasser erst vor Ort zu dem Baustoff gemischt, so daß mit einem Silobehältervolumen relativ viel Baustoff zum Bereiten von Mörtel zur Verfügung steht.A separate feed channel can advantageously open into the mixing device from the outside. This allows additives to be added to the building material on site. For example Water are added so that only dry substances are stored in the silo container. This means that the relatively heavy water is only mixed on site with the building material that with a silo container volume relatively much building material for preparing mortar Available.

In besonderer Weise kann der Zufuhrkanal einen Fülltrichter aufweisen.In a special way, the feed channel can have a filling funnel.

Es wird vorgeschlagen, daß die Dosiervorrichtung in einen Mischtrichter der Mischeinrichtung mündet. In dem Mischtrichter werden die Komponenten aus den Kammern zusammengeführt und vermischen sich.It is proposed that the metering device into a mixing funnel of the mixing device empties. The components from the chambers are brought together in the mixing funnel and mix.

Als Variante der Erfindung kann die Mischeinrichtung einen Zwangsmischer aufweisen. Mit Hilfe des Zwangsmischers werden die Komponenten in der Mischeinrichtung zwangsweise miteinander vermengt, so daß ein homogeneres Gemisch entsteht.As a variant of the invention, the mixing device can have a forced mixer. With the help of the compulsory mixer, the components in the mixing device forcibly mixed together so that a more homogeneous mixture is formed.

Denkbar kann die Mischeinrichtung eine in einem Austragkanal vorgesehene Förderschnecke aufweisen. Die Förderschnecke kann somit als Zwangsmischer für die Komponenten dienen. In der Förderschnecke werden die Komponenten miteinander vermischt und ansatzweise dicht verpreßt, so daß ein kontinuierlicher Baustoffstrom abgegeben werden kann.The mixing device can conceivably be a screw conveyor provided in a discharge channel exhibit. The screw conveyor can therefore be used as a compulsory mixer for the components serve. The components are mixed together in the screw conveyor and partially tightly compressed, so that a continuous flow of building materials is released can be.

Vorzugsweise kann austragsseitig der Mischeinrichtung eine den gemischten Baustoff ausfördernde Abgabepumpe vorgesehen sein. Mit Hilfe der Abgabepumpe wird der zusammengemischte Mehrkomponentenbaustoff abgefördert und kann beispielsweise über eine Schlauchleitung zum gewünschten Einsatzort geführt werden. Die Abgabepumpe sorgt dabei für die notwendige Förderkapazität.The mixed building material can preferably be on the discharge side of the mixing device discharging delivery pump may be provided. With the help of the delivery pump, the mixed Multi-component building materials are removed and can, for example can be routed to the desired location via a hose line.

Ein Dosiermittel ist direkt an das trichterförmige Bodenstück 8 der Kammer 4 angeschlossen. Das andere Dosiermittel 14 ist über einen Verbindungskanal 15 mit dem trichterförmigen Bodenstück 7 der Kammer 3 verbunden. Der Verbindungskanal 15 erstreckt sich großenteils durch die Kammer 4 hindurch. Er verläuft parallel zur Längsachse 5 und ist seitlich etwas gegenüber dem Mittelpunkt der Zylinderform versetzt, während das Dosiermittel 14 der Kammer 4 direkt zentrisch an das trichterförmige Bodenstück 8 mit der Längsachse 5 fluchtend angrenzt. Der Verbindungskanal 15 und das Bodenstück 7 sind als verdeckte Kanten gestrichelt dargestellt, obwohl sie als durchgehende Wände ausgebildet sind und die beiden Kammern 3, 4 vollständig voneinander trennen.A metering device 13 is provided directly below the chambers 3, 4, which has two dosing means 14. A dosing agent is directly on the funnel-shaped Bottom piece 8 of the chamber 4 connected. The other dosing means 14 is one Connection channel 15 connected to the funnel-shaped base 7 of the chamber 3. The connecting channel 15 largely extends through the chamber 4. He runs parallel to the longitudinal axis 5 and is laterally somewhat opposite the center of the Cylindrical shape offset, while the dosing means 14 of the chamber 4 directly in the center the funnel-shaped base piece 8 is aligned with the longitudinal axis 5 in alignment. The connecting channel 15 and the base piece 7 are shown in dashed lines as hidden edges, although they are designed as continuous walls and the two chambers 3, 4 completely separate from each other.

Die Dosiermittel 14 sind jeweils als Zellradpumpen ausgebildet, die von nicht dargestellten Motoren angetrieben werden und eine mengenmäßig portionierte Abnahme des in der jeweiligen Kammer 3, 4 befindlichen Baustoffs bewerkstelligen. The dosing means 14 are each designed as cellular pumps, those of not shown Motors are driven and a quantitative portioned decrease in of the respective chamber 3, 4 located building material.

In Figur 2 ist der prinzipielle Verfahrensablauf als Flußdiagramm dargestellt. Gleiche Bezugszeichen bezeichnen gleiche Bauteile wie in Figur 1, so daß diesbezüglich auf die Beschreibung von Figur 1 verwiesen werden kann. Anhand von Figur 2 kann die Wirkungs- und Funktionsweise des in Figur 1 dargestellten Ausführungsbeispiels eines erfindungsgemäßen Silobehälters erläutert werden.In Figure 2, the basic process flow is shown as a flow chart. Same reference numbers denote the same components as in Figure 1, so that in this regard Description of Figure 1 can be referenced. Based on Figure 2, the effect and functioning of the exemplary embodiment of an embodiment of the invention shown in FIG Silo container are explained.

In den Komponentenkammern 3, 4 sind separat voneinander zwei Komponenten eines Baustoffs bevorratet. Die Dosiervorrichtung 13, die Mischeinrichtung 16 und die Ausgabepumpe 24 werden durch eine Steuereinrichtung gesteuert oder geregelt. Über die Dosiervorrichtung 13 wird mit Hilfe der Dosiermittel 14 aus jeder Kammer ein bestimmter Volumenstrom der jeweiligen Komponente entnommen. Durch Wahl der Schrittweite der die Dosiermittel 14 antreibenden Motoren bzw. durch die Wahl der Drehzahl kann das Mischungsverhältnis bestimmt werden.In the component chambers 3, 4, two components are separate from one another Building material stored. The metering device 13, the mixing device 16 and the output pump 24 are controlled or regulated by a control device. About the Dosing device 13 is a specific from each chamber with the aid of the dosing means 14 Volume flow taken from the respective component. By choosing the step size of the the dosing means 14 driving motors or the choice of speed can do that Mixing ratio can be determined.

Von den Dosiermitteln 14 strömen die Komponenten in den Mischtrichter 17, wo sie zusammengeführt werden und zusammen in den Austragkanal 19 zu der Förderschnecke 18 strömen. Aus einem separaten, außerhalb des Silobehälters liegenden Reservoir 27 kann ein zusätzlicher Stoff, beispielsweise Wasser, über den Fülltrichter 23 zugegeben werden. Die Förderschnecke 18 vermischt die Komponenten, verdichtet sie zu einem homogenen Baustoff und fördert diesen in Richtung zu dem Austragkanal 19. Von dem Austragkanal 19 wird der Baustoff über die Abgabepumpe 24 zum Verspritzen ausgefördert.The components flow from the metering means 14 into the mixing funnel 17, where they are brought together be and together in the discharge channel 19 to the screw conveyor 18 stream. From a separate reservoir 27 located outside the silo container an additional substance, for example water, can be added via the hopper 23 become. The screw conveyor 18 mixes the components, compresses them into one homogeneous building material and conveys it towards the discharge channel 19. From the Discharge channel 19, the building material is discharged via the dispensing pump 24 for spraying.

Über die in Figur 1 dargestellten Einfüllöffnungen 9, 11 können die Komponenten in die jeweilige Kammer 3, 4 eingefüllt werden. Wenn der Silobehälter 1 liegend auf einem Lastkraftwagen angebracht ist, so sind diese Einfüllöffnungen 9, 11 nach oben himmelwärts gerichtet, so daß die Kammern einfach von oben befüllt werden können. Durch die Beabstandung der beiden Einfüllöffnungen 11 der Kammer 4 bildet sich bei horizontaler Lage des Behälters 1 unter beiden Einfüllöffnungen 11 ein etwa kegelförmiger Hügel, so daß die Kammer 4 insgesamt bis auf wenig Freiräume fast vollständig gefüllt werden kann.Via the filling openings 9, 11 shown in Figure 1, the components in the respective chamber 3, 4 are filled. If the silo 1 lying on a Truck is attached, these fill openings 9, 11 are skyward upwards directed so that the chambers can be easily filled from above. Through the The two filling openings 11 of the chamber 4 are spaced apart in the horizontal direction Location of the container 1 under both filling openings 11 an approximately conical hill, so that the chamber 4 are almost completely filled up to a little space can.

Der erfindungsgemäße Silobehälter 1 ist besonders vorteilhaft für Isolierbaustoffe, die als eine Komponente einen relativ leichten Isolierstoff beinhalten, beispielsweise Isoliermörtel mit kleinen Styroporkügelchen darin. In diesem Fall können beispielsweise die Styroporkügelchen in die Kammer 3 gefüllt werden und ein Bindemittel in Form von Trockenpulver in die Kammer 4 gefüllt werden. Das gewünschte Mengenverhältnis wird dann über die Dosiervorrichtung eingestellt. Erst in der Förderschnecke erfolgt die Vermischung und Verpreßung mit Wasser, so daß ein homogen gemischter Isoliermörtel abgegeben wird.The silo container 1 according to the invention is particularly advantageous for insulating building materials which a component contain a relatively light insulating material, for example insulating mortar with little polystyrene balls in it. In this case, for example, the styrofoam beads be filled into the chamber 3 and a binder in the form of dry powder be filled into the chamber 4. The desired ratio is then adjusted via the dosing device. Mixing takes place only in the screw conveyor and grouting with water so that a homogeneously mixed insulating mortar is released becomes.
