Description

Die Erfindung betrifft einen Doppelkonus-Drehmischer entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a double-cone rotary mixer according to the preamble of claim 1.

Ein Doppelkonus-Drehmischer der im Oberbegriff des Anspruches 1 vorausgesetzten Art ist durch die US-A-3 224 741 bekannt. Von den beiden Teilbehältern ist dabei der untere, etwas grösser ausgebildete Teilbehälter mit einer Abzugsöffnung für das Mischgut versehen, während der obere, etwas kleinere Teilbehälter als geschlossener Deckel ausgeführt ist. Unterschiedliche Chargen des Mischgutes, die in dem Drehmischer gemischt werden sollen, müssen bei dieser bekannten Ausführung in den unteren Teilbehälter gegeben werden, der anschliessend durch den deckelartigen oberen Teilbehälter über die Spannvorrichtungen abgeschlossen wird. Der maximale Inhalt dieses bekannten Doppelkonus-Drehmischers entspricht dem grösstmöglichen Inhalt des unteren Teilbehälters.A double cone rotary mixer of the type required in the preamble of claim 1 is known from US-A-3,224,741. Of the two partial containers, the lower, somewhat larger partial container is provided with a discharge opening for the mix, while the upper, somewhat smaller partial container is designed as a closed lid. Different batches of the material to be mixed, which are to be mixed in the rotary mixer, must be placed in the lower part container in this known embodiment, which is then closed by the lid-like upper part container via the clamping devices. The maximum content of this known double cone rotary mixer corresponds to the largest possible content of the lower part of the container.

Es ist weiterhin ein Drehmischer bekannt (GB-A 995 661), bei dem die beiden Teilbehälter durch zylindrische Rohre gebildet werden, die an ihrem äusseren Ende geschlossen sind und an ihrem inneren Ende über ein Gummiventil in Verbindung stehen, so dass bei einer langsamen Drehbewegung des Mischers Schüttgut aus dem einen Teilbehälter durch das Gummiventil in den anderen Teilbehälter (und umgekehrt) überströmt. Die jeweilige Einstellung des Gummiventiles bestimmt den Durchtrittsquerschnitt für das Mischgut zwischen den beiden Teilbehältern.A rotary mixer is also known (GB-A 995 661), in which the two partial containers are formed by cylindrical tubes which are closed at their outer end and are connected at their inner end via a rubber valve, so that during a slow rotary movement of the mixer bulk material from one sub-container flows through the rubber valve into the other sub-container (and vice versa). The respective setting of the rubber valve determines the passage cross-section for the mix between the two sub-containers.

Der Erfindung liegt die Aufgabe zugrunde, einen Doppelkonus-Drehmischer der im Oberbegriff des Anspruches 1 genannten Art so auszubilden, dass er universell verwendbar, leicht zu beschikken und leicht zu reinigen ist und einen einfachen Aufbau aufweist.The invention has for its object to design a double cone rotary mixer of the type mentioned in the preamble of claim 1 so that it can be used universally, is easy to load and easy to clean and has a simple structure.

Diese Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.

Zweckmässige Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Appropriate embodiments of the invention are the subject of the dependent claims.

Die beiden Halbbehälter des erfindungsgemässen Doppelkonus-Drehmischers besitzen eine grosse offene Oberseite, durch die sie leicht zu beschicken und auch bequem zu reinigen sind. Diese Halbbehälter lassen sich mit einfachen Transportvorrichtungen nacheinander an den Ring des Drehmischers ansetzen, wobei die offene Oberseite des gerade anzusetzenden Halbbehälters jeweils nach oben weist. Beim Ansetzen des zweiten Halbbehälters an den Ring wird zu diesem Zweck die am Ring vorgesehene Absperrplatte in die Sperrstellung geschwenkt, wonach sich der bereits mit dem Ring verbundene erste Halbbehälter nach oben drehen lässt, so dass nun der zweite Halbbehälter von unten an den Ring angesetzt werden kann. Sodann wird die Absperrplatte wieder ip die Öffnunasstellung geschwenkt, wonach der Mischvorgang durch Drehen des Mischbehälters beginnen kann.The two half-containers of the double-cone rotary mixer according to the invention have a large open top, through which they are easy to load and also easy to clean. These half-containers can be attached to the ring of the rotary mixer one after the other with simple transport devices, the open top of the half-container to be attached facing upwards in each case. For this purpose, when the second half-container is attached to the ring, the shut-off plate provided on the ring is pivoted into the blocking position, after which the first half-container already connected to the ring can be turned upwards, so that the second half-container is now attached to the ring from below can. Then the shut-off plate is again pivoted ip the opening position, after which the mixing process can begin by turning the mixing container.

Nach Abschluss des Mischvorganges werden die Halbbehälter einzeln abgenommen, wobei sich die Absperrplatte in der Sperrstellung befindet, während der erste Halbbehälter in der unteren Lage abgenommen wird und sich demgemäss der zweite Halbbehälter in der oberen Lage befindet.After the mixing process has been completed, the half containers are removed individually, the shut-off plate being in the locked position, while the first half container is removed in the lower position and the second half container is accordingly in the upper position.

Die Halbbehälter, die zweckmässig eine Bodenauslassöffnung besitzen, können einzeln als Transport-, Lager- und/oder Beschickungsbehälter verwendet werden. Durch diese universelle Verwendbarkeit können Funktionen, die dem Mischvorgang vor-oder nachgeschaltet sind, wesentlich rationeller gestaltet werden. Die Halbbehälter des erfindungsgemässen Drehmischers können auch als Arbeits- oder Beschickungsbehälter für nachfolgende Bearbeitungsstufen dienen.The half-containers, which expediently have a bottom outlet opening, can be used individually as transport, storage and / or loading containers. This universal usability makes it possible to design functions which are upstream or downstream of the mixing process to be considerably more efficient. The half containers of the rotary mixer according to the invention can also serve as working or loading containers for subsequent processing stages.

Für unterschiedliches Mischgut können gesonderte Halbbehälter bereitgehalten werden, so dass nicht die Gefahr einer gegenseitigen Verunreinigung aufeinanderfolgender Chargen besteht.Separate half-containers can be kept ready for different mixes, so that there is no risk of mutual contamination of successive batches.

Der Doppelkonus-Drehmischer nach der Erfindung umfasst einen Ständer 1 in einer stabilen Trag- oder Rahmenkonstruktion. Am Oberende des Ständers 1 befindet sich ein Lagergehäuse 2 zur Lagerung der Welle 3', die eine Drehachse 3 bildet. Ein Getriebe 4 sowie ein Motor 5 dienen zum Antrieb der Welle 3'. Auf die Welle 3' ist ein Ring 6 montiert, wobei die Drehachse 3 radial durch das Zentrum des Ringes 6 verläuft. Der Ring 6 besitzt an seinen Stirnflächen jeweils Ringspannflächen 7 und 7'. Ausserdem sind Spannvorrichtungen 8 und 8' vorhanden, die den Ringspannflächen 7 und 7' zugeordnet sind.The double-cone rotary mixer according to the invention comprises a stand 1 in a stable support or frame construction. At the upper end of the stand 1 there is a bearing housing 2 for supporting the shaft 3 ', which forms an axis of rotation 3. A gear 4 and a motor 5 serve to drive the shaft 3 '. A ring 6 is mounted on the shaft 3 ', the axis of rotation 3 running radially through the center of the ring 6. The ring 6 has ring clamping surfaces 7 and 7 'on its end faces. In addition, there are clamping devices 8 and 8 'which are assigned to the ring clamping surfaces 7 and 7'.

Senkrecht zur Drehachse 3 ist eine Schwenkachse 9 vorgesehen, die ebenfalls radial durch das Zentrum des Ringes 6 geht. Auf der Achse 9 ist eine Absperrplatte 10 schwenkbar gehalten. Ein Handrad 11 oder ein anderer Antrieb ermöglichen eine Verschwenkung der Absperrplatte um einen Winkel von nahezu 90° um die Schwenkachse 9. Die Ringspannflächen weisen auf der Innenseite des Ringes 6 Ringstufen auf, die als Dichtflächen dienen.A swivel axis 9 is provided perpendicular to the axis of rotation 3 and also goes radially through the center of the ring 6. On the axis 9, a shut-off plate 10 is pivotally held. A handwheel 11 or another drive enables the shut-off plate to be pivoted through an angle of almost 90 ° about the pivot axis 9. The ring clamping surfaces have 6 ring steps on the inside of the ring, which serve as sealing surfaces.

Unterhalb des Zentrums des Ringes 6 ist eine Hubvorrichtung 12 vorgesehen, die mit einem hydraulischen oder pneumatischen Antrieb 13 ausgestattet ist.A lifting device 12 is provided below the center of the ring 6 and is equipped with a hydraulic or pneumatic drive 13.

Zu dem Doppelkonus-Drehmischer nach der Erfindung gehören ferner zwei Halbbehälter 14 und 14'. Jeder Halbbehälter 14 bzw. 14' ist als einseitig offener Behälter ausgebildet und umfasst einen Zylinderabschnitt 15 sowie einen konischen Bodenteil 16. Innerhalb des konischen Bodenteils 16 ist eine Ausgabevorrichtung 17 z. B. eine verschliessbare Ausgabeöffnung vorgesehen. An der Oberseite befindet sich eine Anlagefläche 18, die zu der Ringspannfläche 7 bzw. 7' des Ringes 6 passt. Ein Wagen 19 dient zur Aufnahme und Verfahrung je eines Halbbehälters 14 bzw. 14'. Die beiden Halbbehälter 14 und 14' lassen sich in der aus Fig. 4 ersichtlichen Weise an dem Ring 6 festspannen, so dass die Halbbehälter einen DoppelKonus-Mischbehälter bilden.The double-cone rotary mixer according to the invention also includes two half-containers 14 and 14 '. Each half-container 14 or 14 'is designed as a container which is open on one side and comprises a cylinder section 15 and a conical bottom part 16. Inside the conical bottom part 16 there is an output device 17 for. B. a closable dispensing opening is provided. At the top there is a contact surface 18 which fits the ring clamping surface 7 or 7 'of the ring 6. A carriage 19 is used to receive and move a half container 14 or 14 '. The two half-containers 14 and 14 'can be clamped to the ring 6 in the manner shown in FIG. 4, so that the half-containers form a double-cone mixing container.

Die Funktion des Doppelkonus-Drehmischers ist wie folgt: Der Ring 6 steht in der Grundstellung nach Fig. 1 bereit. Der erste Halbbehälter 14 ist mit Mischgut gefüllt und kann auf einem Wagen 19 herangefahren werden. Nachdem der Wagen 19 unterhalb des Ringes 6 positioniert ist, wird der Halbbehälter 14 mit Hilfe der Hubvorrichtung 12 angehoben, vergl. Fig. 2, bis die Anlagefläche 18 an der Ringspannfläche 7' anliegt. Mit Hilfe der Spannvorrichtungen 8' wird der Halbbehälter 14 festgespannt. Die Hubvorrichtung 12 wird abgesenkt und der Wagen 19 kann in die strichpunktiert eingezeichnete Stellung 19' zurückgefahren werden.The function of the double cone rotary mixer is as follows: The ring 6 is ready in the basic position according to FIG. 1. The first half container 14 is filled with mixed material and can be brought up on a carriage 19. After the carriage 19 is positioned below the ring 6, the half-container 14 is raised with the aid of the lifting device 12, see FIG. 2, until the contact surface 18 bears against the ring clamping surface 7 '. With the help of the clamping devices 8 ', the half-container 14 is clamped. The lifting device 12 is lowered and the carriage 19 can be moved back to the position 19 'shown in dash-dot lines.

Die Welle 3' wird nunmehr um die Drehachse 3 um 180° gedreht. Die Absperrplatte 10, die den Querschnitt des Ringes 6 ausfüllt, verhindert, dass der Inhalt des Halbbehälters 14 nach unten fällt. Es kann der zweite Halbbehälter 14' herangefahren werden. Der zweite Halbbehälter 14' wird in ähnlicher Weise mittels der Hubvorrichtung 12 angehoben und durch die Spannvorrichtung 8' auf der Ringspannfläche 7' festgespannt. Es sind dann die beiden Halbbehälter in der aus Fig. 4 ersichtlichen Weise an dem Ring 6 festgespannt. Die beiden Halbbehälter bilden so einen Doppelkonus-Mischbehälter. Die Absperrplatte 10 wird um die Schwenkwelle 9 um nahezu 90° in die Stellung nach Fig. 5 verschwenkt. Der Doppelkonus-Mischbehälter kann jetzt um die Drehachse 3 gedreht werden. Es erfolgt dann eine Durchmischung des Mischgutes unter Ausnutzung der Fallenergie. Die geneigt eingestellte Absperrplatte 10 unterstützt den Mischvorgang. Das Mischgut wird schonend gemischt. Nach vollständiger Mischung wird die Absperrplatte wieder in ihre Sperrlage zurückbewegt. Der untere Halbbehälter wird gelöst und weggefahren. Nach Verschwenken des Ringes 6 kann auch der Zweite Halbbehälter gelöst und abgefahren werden.The shaft 3 'is now rotated about the axis of rotation 3 by 180 °. The shut-off plate 10, which fills the cross section of the ring 6, prevents the contents of the half-container 14 from falling down. The second half container 14 'can be moved up. The second half-container 14 'is raised in a similar manner by means of the lifting device 12 and clamped on the ring clamping surface 7' by the clamping device 8 '. The two half-containers are then clamped to the ring 6 in the manner shown in FIG. 4. The two half tanks form a double cone mixing tank. The shut-off plate 10 is pivoted about the pivot shaft 9 by almost 90 ° in the position shown in FIG. 5. The double cone mixing container can now be rotated about the axis of rotation 3. The mixed material is then mixed using the fall energy. The inclined shut-off plate 10 supports the mixing process. The mix is mixed gently. After complete mixing, the shut-off plate is moved back into its locked position. The lower half container is released and moved away. After the ring 6 has been pivoted, the second half-container can also be released and moved away.

Am Ring selbst treten keine Reinigungsprobleme auf. Es kommt überhaupt nur eine schmale Übergangsfläche zwischen den Ringspannflächen 7 und 7' mit dem Mischgut in Berührung. Diese Übergangsfläche kann praktisch auf eine Dichtlippe reduziert werden. Jedenfalls lässt sich diese Übergangsfläche leicht reinigen. Die einzelnen Halbbehälter können jeweils für gleichartige Chargen von Mischgut benutzt werden, so dass eine Reinigung nur in grösseren Zeitabständen erforderlich ist. Für anderes Mischgut kann man andere Halbbehälter bereithalten, so dass eine Vermischung oder Verunreinigung unterschiedlicher Chargen nicht möglich ist. Man kann auch den Ständer 1 heb- und senkbar ausbilden, um so die Halbbehälter aufnehmen zu können.There are no cleaning problems on the ring itself. Only a narrow transition surface between the ring clamping surfaces 7 and 7 'comes into contact with the mix. This transition area can practically be reduced to a sealing lip. In any case, this transition area is easy to clean. The individual half-containers can each be used for similar batches of mixed material, so that cleaning is only required at longer intervals. Other semi-containers can be kept ready for other mixes, so that mixing or contamination of different batches is not possible. The stand 1 can also be raised and lowered so that the half-containers can be accommodated.
