Definitions
- the invention relates to a mixing device of preferably dry.
- Mixtures in particular based on mineral, organic and / or plastic, such as dry mortar, concrete, feed, fertilizer, food or the like, with metering devices, control devices and transfer devices for loading transport vehicles.
- Such mixing devices are known.
- Mixing systems for ready-mixed mortar in particular, work with stocks in the area of finished goods, because for each type of mortar that has to be loaded loosely, a finished goods silo must be provided within the device. This allows different products to be mixed one after the other and temporarily stored in these finished goods silos.
- the associated metering / mixing and transfer devices generally have to be cleaned between each product changeover.
- the intermediate storage in silos also requires additional mechanical effort in the area of these silos, e.g. B. in addition, an elevator for transporting up and from each silo a conveyor, for example a screw conveyor or the like.
- the intermediate storage in storage silos has above all Dry building material mixtures, and in particular in the case of plasters and mortars, has the sensitive disadvantage that the risk of segregation is increased because with each transfer of such a mixture, the material parts occurring in the mixture with very different grain sizes can be separated from one another. Furthermore, these intermediate storage containers each require measuring or display devices which determine the respective loading quantity precisely regardless of the previous preparation of the mixture.
- the invention is therefore based on the object of creating a mixing device of the type mentioned at the outset, with which the mechanical outlay can be considerably reduced, while vehicles should be able to load different building material mixtures at any time in any or almost any order.
- the solution to this problem consists essentially in the fact that the mixing device is provided without an intermediate store for the finished mixtures and with a mixer which can be emptied without residues and with self-cleaning transport devices from the mixer to the transfer device or devices.
- the batch mixer no longer contains any residues after each emptying, so that immediately after its emptying it can produce a modified mixture which is not adulterated by a previous mixture.
- the discharge opening of the mixer can be arranged above or in a funnel with a closure for decelerated, also residue-free emptying.
- a mechanical or pneumatic conveyor preferably a conveyor belt in dustproof form or an air conveyor trough or the like, can be provided under the funnel.
- An expedient embodiment of the invention can consist in that a conveyor screw is provided as the conveyor, parallel to which a lower-lying cleaning screw is arranged, which during cleaning in reverse is drivable in the opposite direction and then opens over a waste container or the like.
- the normal screw conveyor can thus bring the mixed good to its destination.
- certain residues cannot be completely avoided when changing the mixing ratios in the area of screw conveyors, such a residue can also be eliminated by reversing the conveying direction with the aid of the cleaning screw, so that after a short time, no components from a previous mixture are present in the area of this conveyor there are more.
- the conveying means can be drivable in both directions of extension and act on at least two transfer devices. As a result, the entire mixing device can be used even more effectively because a second vehicle can already be brought into the loading position while a vehicle is being loaded.
- an approximately horizontally arranged, drum-shaped mixer can be used as the mixer Batch mixer may be provided, the lower wall area of which can be opened completely for emptying, the opening angle being greater than the slope angle of the material to be mixed. If the bottom wall of such a batch mixer is opened or removed for opening, the entire mix slips out, because it cannot and cannot partially hold due to the angular relationships mentioned. If the opening angle of the batch mixer is greater than the slope angle of the residual mix that remains between the wall and mixing blades of the mixer during the mixing process, the safety of the residue-free emptying is particularly high.
- An expedient embodiment of the invention can consist in that the lower wall area of the mixer can be closed by at least one flap or the like, preferably by two flaps which can be swung away from one another.
- This allows a very simple opening downwards, through which the majority of the mixer contents are released downwards. Even the left-hand remnants of the material to be mixed cannot remain in the drum-shaped mixer, since they cannot form a sufficiently stable slope.
- the lower opening area can comprise about a third of the entire mixer circumference and is in particular arranged in the middle. The lower wall area of the mixer, which does not belong to the opening and is close to the opening, is then already so steep that a dry mixture cannot remain there even in small residues.
- the hinge or hinges of the lower opening flaps are expediently on the outside of the jacket of the mixer and the corresponding fittings on the outside of those forming the lower part of the mixer wall Opening flaps attached so that there are no projections or the like on the inside of the mixer, to which small residues of mixed material could possibly stick.
- the inside of the opening flaps can be flush with the inside of the mixer wall.
- the flap or the flaps can have the same radius of curvature and, in the closed position, the same center of curvature as the rest of the container wall, so that no irregularities occur in the interior of the batch mixer during the mixing process, which could adversely affect the mixing result.
- the lower opening can extend up to the end walls of the mixer and these end walls can form the front or rear boundary of the lower opening. As a result, the formation of an edge on which the mixed material could remain may also be avoided in the end regions of the mixer.
- a mixing device designated as a whole by 1, contains in its interior metering devices 2, which feed various mixture components in the required quantities from corresponding containers with the interposition of control devices 3 and funnels 4 to a mixer 5 to be described in more detail.
- this mixing device 1 It is characteristic of this mixing device 1 that no intermediate containers are provided, into which a finished mixture can be introduced until the switch to a different mixture with the associated cleaning of the various units is worthwhile. Rather, the mixer 5 is designed as a horizontally arranged drum-shaped batch mixer that can be emptied without residue, the lower wall area of which, according to FIGS. 2 and 3, can be completely opened for emptying, the opening angle being greater than the slope angle of the mixed material. Each time the material is emptied, the mixture is left behind in this mixer, so that a different composition of a mixture can now also be introduced and mixed. This makes it practically possible to produce a different mixture for each mixture after each batch, simply by changing the metering and control devices accordingly. In this way, intermediate containers for the intermediate storage of various mixtures are unnecessary.
- the opening angle of the batch mixer i is greater than the slope angle of the residual mixture 6, which may otherwise remain between the wall 7 and the mixing blades 8 of the mixer 5 during the mixing process.
- Fig. 1 it is also indicated that the emptying opening 9 of the mixer 5 is arranged above or in a funnel 10 with a closure 11 for decelerated emptying and that a conveyor belt 12, preferably a conveyor belt in dustproof form, is provided under the funnel 10.
- the casing 13 of the conveyor belt 12 can be seen in a schematic arrangement in FIG. 1.
- the funnel 10 can hold the contents of the batch mixer 5 in its interior, so that this mixed material can be slowly transferred to the conveyor belt 12.
- the conveyor belt 12 can be driven in its two extension directions, so that two transfer devices 14, 18 can be acted upon.
- Fig. 1 you can see in the left part of a direct transition from the conveyor belt 12 in a transfer device 14 with filling nozzle 15 to a vehicle 16, while the right part of the conveyor belt 12 opens over another conveyor belt 17, which in turn can feed two places, namely a second transfer device 18 with a filling nozzle 15 for a vehicle 19 or, for special cases, a transfer station 20 with which the mixed material can be transported further.
- the lower wall area of the mixer 5 can be closed with at least one flap, closure or the like, in the exemplary embodiment with two flaps 21 which can be pivoted away from one another.
- the lower opening area takes up about a third of the entire mixer circumference and is arranged in the center. It can clearly be seen that in the direct connection to the flaps 21 the cylindrical wall 7 of the mixer 5 is already so steep that dry mix can no longer attach and hold here when the flaps 21 are opened.
- the mixers, which previously had openings in the lower area generally have openings so small that residual mixture can still remain everywhere, which would then have to be discharged with special tools or with compressed air.
- the hinges 22 running along the opening edges can advantageously be designed as a stiffener of the mixer 5 or vice versa, stiffeners can be arranged in this area, which are at the same time for receiving or formation of the hinges 22 can be used.
- the one or more hinges 22 are attached to the outside of the jacket 7 of the mixer 5 and the corresponding fittings 23 to the outside of the opening flaps 21 forming the lower part of the mixer wall. If it is expedient for the stiffening of the mixer 5, in particular in the area of its large opening 9, the hinges 22 may also have corresponding counterparts on the mixer 5 itself for the fittings 23.
- the opening flaps 21 are designed such that they are flush with the inside of the mixer wall 7 in the closed position with their inside. As a continuation of the mixing head 7, they have the same radius of curvature and, in the closed position, the same center of curvature as the rest of the mixer wall.
- a batch mixer 5 has been formed by relatively simple measures, which can be emptied without residues due to its large opening alone, without special additional tools, which in itself is a great advantage for different applications.
- the entire mixing device 1 thus becomes simpler and cheaper.
- FIGS. 4 and 5 show an embodiment of the mixing device 1, in which, below the hopper 10, into which the mixer 5 is emptied, a conveyor screw 25 is also arranged as a conveying means within a dustproof housing 26, which in the exemplary embodiment has two transfer devices 14 can operate 16 and 19 for two vehicles.
- a screw conveyor can be used in this area of the device 1.
- a cleaning screw 27 is located directly below it in a corresponding conical area parallel to this screw conveyor 25 28 of the housing 26 arranged.

Description
Die Erfindung betrifft eine Mischvorrichtung von vorzugsweise trockenen.Mischungen insbesondere auf mineralischer, organischer und/oder Kunststoffbasis wie Trockenmörtel, Beton, Futter-, Düngemittel, Lebensmittel od. dgl. mit Dosiereinrichtungen, Steuereinrichtungen und übergabevorrichtungen zum Beladen von Transportfahrzeugen.The invention relates to a mixing device of preferably dry. Mixtures, in particular based on mineral, organic and / or plastic, such as dry mortar, concrete, feed, fertilizer, food or the like, with metering devices, control devices and transfer devices for loading transport vehicles.
Derartige Mischvorrichtungen sind bekannt. Vor allem Mischanlagen für Fertigmörtel arbeiten dabei mit einer Vorratshaltung im Fertiggutbereich, weil für jede Mörtelsorte, die lose verladen werden muß ein Fertiggutsilo innerhalb der Vorrichtung vorzusehen ist. Dies erlaubt es, nacheinander verschiedene Produkte zu mischen und jeweils in diesen Fertiggutsilos zwischenzulagern. Zwischen jeder Produktumstellung müssen die zugehörigen Dosier-Misch- und übergabevorrichtungen in der Regel gereinigt werden. Die Zwischenlagerung in Silos erfordert auch im Bereich dieser Silos zusätzlichen maschinellen Aufwand, z. B. zusätzlich einen Elevator zum Hochtransportieren und von jedem Silo aus eine Fördereinrichtung, beispielsweise eine Transportschnecke od. dgl. zu einer Übergabevorrichtung zum Beladen von Fahrzeugen-Die Zwischenlagerung in Vorratssilos hat vor allem bei trockenen Baustoffmischungen und insbesondere bei Putzen und Mörteln den empfindlichen Nachteil, daß die Entmischungsgefahr vergrößert wird, weil bei jedem Umfüllen eines solchen Mischgutes die in sehr unterschiedlicher Körnung innerhalb der Mischung vorkommenden Materialteile voneinander getrennt werden können. Ferner benötigen diese Zwischenlagerbehälter jeweils Meß- oder Anzeigevorrichtungen, die unabhängig von der vorangegangenen Herstellung der Mischung die jeweilige Verlademenge genau bestimmen.Such mixing devices are known. Mixing systems for ready-mixed mortar, in particular, work with stocks in the area of finished goods, because for each type of mortar that has to be loaded loosely, a finished goods silo must be provided within the device. This allows different products to be mixed one after the other and temporarily stored in these finished goods silos. The associated metering / mixing and transfer devices generally have to be cleaned between each product changeover. The intermediate storage in silos also requires additional mechanical effort in the area of these silos, e.g. B. in addition, an elevator for transporting up and from each silo a conveyor, for example a screw conveyor or the like. To a transfer device for loading vehicles-The intermediate storage in storage silos has above all Dry building material mixtures, and in particular in the case of plasters and mortars, has the sensitive disadvantage that the risk of segregation is increased because with each transfer of such a mixture, the material parts occurring in the mixture with very different grain sizes can be separated from one another. Furthermore, these intermediate storage containers each require measuring or display devices which determine the respective loading quantity precisely regardless of the previous preparation of the mixture.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Mischvorrichtung der eingangs erwähnten Art zu schaffen, mit der der maschinelle Aufwand erheblich vermindert werden kann, während dennoch in beliebiger oder nahezu beliebiger Reihenfolge Fahrzeuge unterschiedliche Baustoffmischungen jeder Zeit laden können sollen.The invention is therefore based on the object of creating a mixing device of the type mentioned at the outset, with which the mechanical outlay can be considerably reduced, while vehicles should be able to load different building material mixtures at any time in any or almost any order.
Die Lösung dieser Aufgabe besteht im wesentlichen darin, daß die Mischvorrichtung ohne Zwischenlager für die fertigen Mischungen und mit einem rückstandfrei-entleerbaren Mischer sowie mit selbstreinigenden Transporteinrichtungen von dem Mischer zu der oder den übergabevorrichtungen versehen ist.The solution to this problem consists essentially in the fact that the mixing device is provided without an intermediate store for the finished mixtures and with a mixer which can be emptied without residues and with self-cleaning transport devices from the mixer to the transfer device or devices.
Dadurch wird erreicht, daß der Chargenmischer nach jeder Entleerung keinerlei Rückstände mehr enthält, so daß er im unmittelbaren Anschluß an seine Entleerung eine abgewandelte Mischung herstellen kann, die nicht durch eine vorangegangene Mischung verfälscht wird. Das gleiche gilt für die Transporteinrichtungen vom Mischer zu den übergabevorrichtungen, so daß die gesamte Mischvorrichtung je nach Bedarf ein ankommendes Fahrzeug mit einer gewünschten Produktmischung beladen kann, ohne dass Zwischenbehälter benötigt werden. Dadurch entfallen nicht nur diese Zwischenbehälter, sondern auch die Beschickungs- und Entleerungseinrichtungen und die Mengenmeßvorrichtungen dieser Zwischenbehälter, so daß die gesamte Mischvorrichtung oder Mischanlage eine wesentlich geringere Investition erforderlich macht, weniger Wartungsaufwand benötigt und kürzere Transportwege mit geringerer Antriebsenergie und entsprechend geringerem Verschleiß hat. Dabei ist gegenüber einer Mischvorrichtung mit Zwischenbehältern sogar noch der Vorteil gegeben, daß jede Produktmischung gewissermaßen sofort zur Verfügung gestellt werden kann, während im Falle einer Anlage mit Zwischenbehältern unter Umständen ein solcher Zwischenbehälter gerade entleert sein kann und die Anlage eine andere Mischung herstellt, so daß manche Produkte gegebenenfalls nicht immer sofort zur Verfügung stehen.It is thereby achieved that the batch mixer no longer contains any residues after each emptying, so that immediately after its emptying it can produce a modified mixture which is not adulterated by a previous mixture. The same applies to the transport devices from the mixer to the transfer devices, so that the entire mixing device can load an incoming vehicle with a desired product mixture as required, without the need for intermediate containers. This eliminates not only these intermediate containers, but also the loading and emptying devices and the quantity measuring devices of these intermediate containers, so that the entire mixing device or mixing system requires a significantly lower investment, requires less maintenance and has shorter transport routes with lower drive energy and correspondingly less wear and tear. Compared to a mixing device with intermediate containers, there is even the advantage that any product mixture can be made available immediately, while in the case of a system with intermediate containers such an intermediate container may just be emptied and the system produces another mixture, so that some products may not always be available immediately.
In überraschender Weise wird also auf eine Zwischenlagerung der fertigen Mischung, die-bisher bei Mischanlagen für unterschiedliche Produkte für unbedingt notwendig gehalten wurde, verzichtet. Entsprechend.verringert ist auch die Gefahr von Entmischungen der jeweils hergestellten Baustoffmischung.Surprisingly, intermediate storage of the finished mixture, which was previously considered to be absolutely necessary for mixing systems for different products, is therefore dispensed with. The risk of segregation of the building material mixture produced in each case is correspondingly reduced.
Die Entleeröffnung des Mischers kann über oder in einem Trichter mit Verschluß zum abgebremsten, ebenfalls rückstandfreien Entleeren angeordnet sein. Unter dem Trichter kann ein mechanischer oder pneumatischer Förderer, vorzugsweise ein Förderband in staubdichter Form oder eine Luftförderrinne od. dgl. vorgesehen sein.The discharge opening of the mixer can be arranged above or in a funnel with a closure for decelerated, also residue-free emptying. A mechanical or pneumatic conveyor, preferably a conveyor belt in dustproof form or an air conveyor trough or the like, can be provided under the funnel.
Eine zweckmäßige Ausführungsform der Erfindung kann darin bestehen, daß als Förderer eine Förderschnecke vorgesehen ist, parallel zu welcher eine tiefer liegende Reinigungsschnecke angeordnet ist, die bei der Reinigung in umgekehrter Richtung antreibbar ist und dann über einem Abfallbehälter od. dgl. mündet. Bei normaler Beförderung kann die normale Förderschnecke somit das gemischte Gut zu seinem Bestimmungsort bringen. Da jedoch beim Wechsel der Mischungsverhältnisse im Bereich von Förderschnecken gewisse Rückstände nicht ganz zu vermeiden sind, kann durch umgekehrte Förderrichtung mit Hilfe der Reinigungsschnecke auch ein solcher Rückstand beseitigt werden, so daß nach kurzer Zeit auch im Bereich dieses Fördermittels keine von einer vorhergehenden Mischung stammenden Bestandteile mehr vorhanden sind.An expedient embodiment of the invention can consist in that a conveyor screw is provided as the conveyor, parallel to which a lower-lying cleaning screw is arranged, which during cleaning in reverse is drivable in the opposite direction and then opens over a waste container or the like. With normal transportation, the normal screw conveyor can thus bring the mixed good to its destination. However, since certain residues cannot be completely avoided when changing the mixing ratios in the area of screw conveyors, such a residue can also be eliminated by reversing the conveying direction with the aid of the cleaning screw, so that after a short time, no components from a previous mixture are present in the area of this conveyor there are more.
Das Fördermittel kann in beide Erstreckungsrichtungen antreibbar sein und wenigstens zwei übergabevorrichtungen beaufschlagen. Dadurch kann die gesamte Mischvorrichtung noch effektiver benutzt werden, weil während der Beladung eines Fahrzeuges bereits ein zweites Fahrzeug in Ladeposition gebracht werden kann.The conveying means can be drivable in both directions of extension and act on at least two transfer devices. As a result, the entire mixing device can be used even more effectively because a second vehicle can already be brought into the loading position while a vehicle is being loaded.
Ein wesentlicher Teil der Erfindung ist in dem rückstandfrei entleerbaren Mischer zu sehen, daß dieser ein besonders schnelles Umschalten von einer Produktmischung auf die andere erlaubt, ohne daß Zwischenbehälter notwendig sind. Praktisch kann schon nach einer Charge, da diese ohne Rückstände aus dem Mischer entfernt wird, eine andere Mischung hergestellt werden. Dieser Vorteil des Mischers ist jedoch auch in anderen Anwendungen denkbar, so daß die Ausbildung des Mischers, die die rückstandfreie Entleerung in besonders vorteilhafter und einfacher Weise ermöglicht, gleichzeitig als Erfindung von eigener schutzwürdiger Bedeutung angesehen wird. Um zu erreichen, daß der Mischer rückstandfrei entleerbar ist, ohne daß dazu besondere Blas-, Schabe- od. dgl. Einrichtungen im Mischer vorhanden sein müssen, kann als Mischer ein etwa horizontal angeordneter, trommelförmiger Chargenmischer vorgesehen sein, dessen unterer Wandungsbereich für die Entleerung vollständig öffenbar ist, wobei der Öffnungswinkel größer als der Böschungswinkel des Mischgutes ist. Wird bei einem derartigen Chargenmischer die untere Wandung geöffnet bzw. zum Öffnen entfernt, rutscht das gesamte Mischgut heraus, da es sich aufgrund der erwähnten Winkelverhältnisse nicht und auch nicht teilweise halten kann. Wird der Öffnungswinkel des Chargenmischers größer als der Böschungswinkel des Restmischgutes, welches zwischen der Wandung und Mischflügeln des Mischers während des Mischvorganges liegen bleibt, gewählt, ist die Sicherheit der rückstandfreien Entleerung besonders groß.An essential part of the invention can be seen in the mixer, which can be emptied without residues, that this allows a particularly rapid changeover from one product mixture to the other, without the need for intermediate containers. In practice, another batch can be made after just one batch, since it is removed from the mixer without residues. However, this advantage of the mixer is also conceivable in other applications, so that the design of the mixer, which enables residue-free emptying in a particularly advantageous and simple manner, is simultaneously regarded as an invention of its own worthy protection. In order to ensure that the mixer can be emptied without residues, without the need for special blowing, scraping or similar devices in the mixer, an approximately horizontally arranged, drum-shaped mixer can be used as the mixer Batch mixer may be provided, the lower wall area of which can be opened completely for emptying, the opening angle being greater than the slope angle of the material to be mixed. If the bottom wall of such a batch mixer is opened or removed for opening, the entire mix slips out, because it cannot and cannot partially hold due to the angular relationships mentioned. If the opening angle of the batch mixer is greater than the slope angle of the residual mix that remains between the wall and mixing blades of the mixer during the mixing process, the safety of the residue-free emptying is particularly high.
Eine zweckmäßige Ausführungsform der Erfindung kann darin bestehen, daß der untere Wandungsbereich des Mischers von wenigstens einer Klappe od, dgl. Verschluß, vorzugsweise von zwei voneinander_wegschwenkbaren Klappen verschließbar ist. Dies erlaubt eine sehr einfache Öffnung nach unten, durch die zunächst einmal der größte Teil des Mischer-Inhaltes nach unten freigegeben wird. Auch die seitlichen Reste des Mischgutes können sich aber in dem trommelförmigen Mischer nicht halten,-da sie keine genügend stabile Böschung bilden können. Beispielsweise kann der untere öffnungsbereich etwa ein Drittel des gesamten Mischerumfanges umfassen und ist dabei insbesondere mittig angeordnet. Der nicht zur Öffnung gehörende untere, der öffnung nahe Wandbereich des Mischers ist dann bereits so steil, daß sich eine Trockenmischung auch in kleinen Resten dort nicht halten kann.An expedient embodiment of the invention can consist in that the lower wall area of the mixer can be closed by at least one flap or the like, preferably by two flaps which can be swung away from one another. This allows a very simple opening downwards, through which the majority of the mixer contents are released downwards. Even the left-hand remnants of the material to be mixed cannot remain in the drum-shaped mixer, since they cannot form a sufficiently stable slope. For example, the lower opening area can comprise about a third of the entire mixer circumference and is in particular arranged in the middle. The lower wall area of the mixer, which does not belong to the opening and is close to the opening, is then already so steep that a dry mixture cannot remain there even in small residues.
Das oder die Scharniere der unteren Öffnungsklappen sind zweckmäßigerweise an der Außenseite des Mantels des Mischers und die entsprechenden Beschläge an der Außenseite der den unteren Teil der Mischerwandung bildenden Öffnungsklappen angebracht, damit im Inneren des Mischers keine Vorsprünge od. dgl. entstehen, an denen eventuell geringe Mischgutreste haften bleiben könnten. In Schließstellung können die Öffnungsklappen mit ihrer Innenseite bündig mit der Innenseite der Mischerwandung sein. Ferner kann die Klappe oder können die Klappen als Fortsetzung der Mischerwand den selben Krümmungsradius und in Schließstellung den selben Krümmungsmittelpunkt wie die übrige Behälterwand haben, so daß während des Mischvorganges keine Unregelmäßigkeiten im Inneren des Chargenmischers auftreten, die das Mischergebnis ungünstig beeinflussen könnten.The hinge or hinges of the lower opening flaps are expediently on the outside of the jacket of the mixer and the corresponding fittings on the outside of those forming the lower part of the mixer wall Opening flaps attached so that there are no projections or the like on the inside of the mixer, to which small residues of mixed material could possibly stick. In the closed position, the inside of the opening flaps can be flush with the inside of the mixer wall. Furthermore, as a continuation of the mixer wall, the flap or the flaps can have the same radius of curvature and, in the closed position, the same center of curvature as the rest of the container wall, so that no irregularities occur in the interior of the batch mixer during the mixing process, which could adversely affect the mixing result.
Die untere Öffnung kann bis zu den Stirnwänden des Mischers verlaufen und diese Stirnwände können die vordere bzw. hintere Begrenzung der unteren Öffnung bilden. Dadurch wird auch in den stirnseitigen Bereichen des Mischers das Entstehen eines Randes, auf welchem Mischgut liegen bleiben .könnte, vermieden.The lower opening can extend up to the end walls of the mixer and these end walls can form the front or rear boundary of the lower opening. As a result, the formation of an edge on which the mixed material could remain may also be avoided in the end regions of the mixer.
Insgesamt ergibt sich eine preiswerte, vom maschinellen Aufwand und somit auch vom Platzbedarf verminderte Mischvorrichtung, der ein Chargenmischer zugehört, der aufgrund seiner speziellen Ausbildung ebenfalls ohne besondere Einrichtungen rückstandfrei entleert werden kann. Somit ist die gesamte Vorrichtung und auch der Chargenmischer nach jeder Entleerung sofort bereit, auch eine abgewandelte Mischung aufzunehmen. Da die jeweils in den Chargenmischer gefüllte Menge recht genau gestimmt ist, läßt sich eine entsprechend präzise Beladung von FahrT zeugen durchführen.Overall, there is an inexpensive mixing device, which is reduced in terms of mechanical outlay and thus also of the space requirement, and which includes a batch mixer which, owing to its special design, can also be emptied without residues without special facilities. Thus, the entire device and the batch mixer are immediately ready to take up a modified mixture after each emptying. Since the quantity filled in the batch mixer is very precisely tuned, it is possible to load vehicles with corresponding precision.

Vielmehr ist der Mischer 5 als rückstandfrei entleerbarer, horizontal angeordneter trommelförmiger Chargenmischer ausgebildet, dessen unterer Wandungsbereich gemäß den Figuren 2 und 3 für die Entleerung vollständig öffenbar ist, wobei der Öffnungswinkel größer als der Böschungswinkel des Mischgutes ist. Bei jeder Entleerung wird also ein Zurückbleiben von Mischgut in diesem Mischer vermieden, so daß nun auch eine andere Zusammensetzung einer Mischung eingebracht und gemischt werden kann. Dadurch ist es praktisch möglich, nach jeder Charge-für eine bestimmte Mischung eine andere Mischung herzustellen, indem einfach die Dosier- und Steuereinrichtungen entsprechend umgestellt werden. Auf diese Weise sind Zwischenbehälter zur Zwischenlagerung verschiedener Mischungen entbehrlich.It is characteristic of this
Vor allem in Fig. 2 erkennt man, daß der Öffnungswinkel des Chargenmischersi größer als der Böschungswinkel des Restmischgutes 6 ist, welches andernfalls zwischen der Wandung 7 und den Mischflügeln 8 des Mischers 5 während des Mischvorganges liegen bleiben kann.Above all in Fig. 2 it can be seen that the opening angle of the batch mixer i is greater than the slope angle of the
In Fig. 1 ist noch angedeutet, daß die Entleeröffnung 9 des Mischers 5 über oder in einem Trichter 10 mit Verschluß 11 zum abgebremsten Entleeren angeordnet ist und daß unter dem Trichter 10 ein Förderband 12, vorzugsweise ein Förderband in staubdichter Form vorgesehen ist. Man erkennt in Fig. 1 in schematischer Anordnung die Ummantelung 13 des Förderbandes 12. Der Trichter 10 kann in seinem Inneren den Inhalt des Chargenmischers 5 aufnehmen, so daß dieses Mischgut langsam auf das Förderband 12 übergeleitet werden kann.In Fig. 1 it is also indicated that the emptying opening 9 of the
Im Ausführungsbeispiel ist das Förderband 12 in seine beiden Erstreckungsrichtungen antreibbar, so daß zwei übergabevorrichtungen 14, 18 beaufschlagt werden können. In Fig. 1 erkennt man im linken Teil einen direkten Übergang von dem Förderband 12 in eine übergabevorrichtung 14 mit Füllrüssel 15 zu einem Fahrzeug 16, während der rechte Teil des Förderbandes 12 über einem weiteren Förderband 17 mündet, das seinerseits zwei Stellen beschicken kann, nämlich eine zweite Übergabevorrichtung 18 mit Füllrüssel 15 für ein Fahrzeug 19 oder aber für besondere Fälle eine übergabestation 20, mit der das Mischgut weitertransportiert werden kann.In the exemplary embodiment, the
Der untere Wandungsbereich des Mischers 5 ist mit wenigstens einer Klappe, Verschluß od. dgl., im Ausführungsbeispiel mit zwei voneinander wegschwenkbaren Klappen 21 verschließbar. Dabei nimmt der untere öffnungsbereich etwa ein Drittel des gesamten Mischerumfanges ein und ist mittig angeordnet. Man erkennt deutlich, daß im unmittelbaren Anschluß an die Klappen 21 die zylinderförmige Wandung 7 des Mischers 5 bereits so steil ist, daß sich hier trockenes Mischgut nicht mehr ansetzen und halten kann, wenn die Klappen 21 geöffnet werden. Die bisher im unteren Bereich öffnungen aufweisenden Mischer haben dabei in der Regel so kleine Öffnungen, daß überall noch Restmischgut verbleiben kann, welches dann mit besonderen Werkzeugen oder mit Preßluft ausgetragen werden müßte.The lower wall area of the
Um trotz dieser großen Öffnung 9 ein genügend stabiles Mischergehäuse zu erhalten, können in vorteilhafter Weise die entlang den öffnungsrändern verlaufenden Scharniere 22 als Aussteifung des Mischers 5 ausgebildet sein bzw. umgekehrt können in diesem Bereich Aussteifungen angeordnet sein, die gleichzeitig zur Aufnahme oder Ausbildung der Scharniere 22 herangezogen werden können. Dabei sind das oder die Scharniere 22 an der Außenseite des Mantels 7 des Mischers 5 und die entsprechenden Beschläge 23 an den Außenseiten der den unteren Teil der Mischerwandung bildenden Öffnungsklappen 21 angebracht. Falls es für die Aussteifung des Mischers 5 insbesondere im Bereich seiner großen Öffnung 9 zweckmäßig ist, können von den Scharnieren 22 auch den Beschlägen 23 entsprechende Gegenstücke am Mischer 5 selbst vorhanden sein.In order to obtain a sufficiently stable mixer housing in spite of this
Die Öffnungsklappen 21 sind so ausgebildet, daß sie in Schließstellung mit ihrer Innenseite bündig mit der Innenseite der Mischerwandung 7 sind. Dabei haben sie als Fortsetzung der Misch-erwand 7 denselben Krümmungsradius und in Schließstellung denselben Krümmungsmittelpunkt wie die übrige Mischerwand.The opening flaps 21 are designed such that they are flush with the inside of the mixer wall 7 in the closed position with their inside. As a continuation of the mixing head 7, they have the same radius of curvature and, in the closed position, the same center of curvature as the rest of the mixer wall.
In Fig. 3 erkennt man, daß die untere Öffnung 9 bis zu den Stirnwänden 24 des Mischers 5 verlaufen und diese Stirnwände 24 die vordere bzw. hintere Begrenzung der unteren Öffnung 9 bilden. Es wird also auch hier vermieden, daß ein Rand oder Absatz am übergang zu der Öffnung 9 entsteht, auf dem kleine Mengen von Mischgut liegen bleiben könnten, die die nächste Charge mit anderen Mischungsverhältnissen und -komponenten verfälschen könnten.In Fig. 3 it can be seen that the
Insgesamt ist durch relativ einfache Maßnahmen ein Chargenmischer 5 gebildet worden, der allein aufgrund seiner großen Öffnung ohne besondere Zusatzwerkzeuge rückstandfrei entleert werden kann, was für sich allein schon für unterschiedliche Anwendungsfälle einen großen Vorteil darstellt. Besonders vorteilhaft ist er jedoch innerhalb der Mischvorrichtung 1, weil dadurch diese Mischvorrichtung praktisch übergangslos und ohne Zwischenlagerung dennoch wirtschaftlich von einer Mischung auf eine andere umgestellt werden kann, so daß nacheinander zwei Fahrzeuge 16 und 19 mit verschiedenen Mischungen gefüllt werden können, ohne daß es der erwähnten Zwischenlagerung bedarf. Somit wird die gesamte Mischvorrichtung 1 einfacher und preiswerter.Overall, a
In den Figuren 4 und 5 ist eine Ausführungsform der Mischvorrichtung 1 dargestellt, bei welcher unterhalb des Trichters 10, in den der Mischer 5 entleert wird, als Fördermittel eine Förderschnecke 25 ebenfalls innerhalb eines staubdichten-Gehäuses 26 angeordnet ist, die im Ausführungsbeispiel zwei übergabevorrichtungen 14 für zwei Fahrzeuge 16 und 19 bedienen kann. Dadurch können in diesem Bereich der Vorrichtung 1 die Vorteile einer Förderschnecke nutzbar gemacht werden.FIGS. 4 and 5 show an embodiment of the
Da jedoch beim Stillsetzen einer solchen Förderschnecke insbesondere unterhalb einer solchen Förderschnecke, wo noch ein gewisser Spielraum vorhanden ist, Material eines Förder- und Mischvorganges verbleiben würde, ist in erfindungsgemäßer Weise parallel zu dieser Förderschnecke 25 unmittelbar unter ihr eine Reinigungsschnecke 27 in einem entsprechenden konischen Bereich 28 des Gehäuses 26 angeordnet.However, since material of a conveying and mixing process would remain when such a screw conveyor was stopped, in particular underneath such a screw conveyor, where there is still a certain scope, a cleaning
Ist ein Fördervorgang zu einem der Fahrzeuge 16 oder 19 mit Hilfe der Schnecke 25 beendet und soll die gesamte Vorrichtung 1 auf eine andere Mischung umgestellt werden, kann nun zunächst mit Hilfe der Reinigungsschnecke 27 der in dem Gehäuse 26 befindliche Mischungsrest über Abführleitungen 29 zu einem-entsprechenden Abfallbehälter 30 befördert werden. Dieser kann gegebenenfalls sogar bewegbar ausgebildet sein, um noch in das entsprechende Fahrzeug eingefüllt zu werden.If a conveying process to one of the
