Description

Die Erfindung betrifft einen Doppelkonus-Drehmischer dessen Doppelkonus-Mischbehälter um eine horizontale, senkrecht zur Behälterachse ausgerichtete Drehachse drehbar ist.The invention relates to a double cone rotary mixer whose double cone mixing container can be rotated about a horizontal axis of rotation oriented perpendicular to the container axis.

In einem derartigen Mischer erfolgt die Mischung bekanntlich dadurch, daß sich das Mischgut bei der Drehung des Doppelkonus-Mischbehälters im freien Fall vermischt. Eine unmittelbare Ernergieeinleitung für den Mischvorgang in das Mischgut ist nicht erforderlich. Deshalb ist ein solcher Doppelkonus-Drehmischer in vielen Fällen für die Mischung vorzuziehen.In a mixer of this type, it is known that the mixing takes place in that the material to be mixed mixes in free fall when the double-cone mixing container is rotated. An immediate introduction of energy for the mixing process into the mix is not necessary. Therefore, such a double cone rotary mixer is preferable in many cases for the mixture.

Der Doppelkonus-Mischbehälter besitzt Eingabeöffnungen und Ausgabeöffnungen, die für die Handhabung des Mischbehälters in eine genaue Position gebracht werden müssen. Eine Reinigung des Innern des Doppelkonus-Mischbehälters ist praktisch nicht möglich, da die Eingabeöffnungen und Ausgabeöffnungen vergleichsweise klein sind. Eine zerlegbare Ausbildung des Mischbehälters ist mit einem praktisch vertretbaren Aufwand nicht durchführbar. Infolgedessen ergeben sich Schwierigkeiten, wenn unterschiedliche Mischgüter in einen solchen Doppelkonus-Mischbehälter verarbeitet werden sollen, da dann die Möglichkeit von Verunreinigungen des Mischgutes durch die jeweils vorher bearbeitete Charge besteht.The double cone mixing container has inlet openings and outlet openings which must be brought into an exact position for handling the mixing container. It is practically impossible to clean the inside of the double-cone mixing container since the inlet openings and outlet openings are comparatively small. A detachable design of the mixing container is not feasible with a practically justifiable effort. As a result, difficulties arise when different mixed materials are to be processed in such a double-cone mixing container, since there is then the possibility of contamination of the mixed material by the batch previously processed in each case.

Aufgabe der Erfindung ist eine solche Ausbildung eines Doppelkonus-Drehmischers, daß einerseits eine leichte Reinigung des Mischbehälters möglich ist und daß andererseits Chargen verschiendenen Mischgutes verarbeitet werden können, ohne daß es zu einer gegensei- tigen Beeinträchtigung der verschiedenen Chargen kommt.The object of the invention is such a design of a double-cone rotary mixer that on the one hand an easy cleaning of the mixing container is possible and that on the other hand batches of mixed material can be processed without it to a mutual the various batches.

Diese Aufgabe wird nach der Erfindung durch folgende Merkmale gelöst:

  • a) die Drehachse trägt einen Ring;
  • b) der Ring besitzt an seinen Stirnflächen zwei Ringspannflächen mit Spannvorrichtungen;
  • c) eine den Innenquerschnitt des Ringes ausfüllende Absperrplatte ist um eine Achse schwenkbar angeordnet;
  • d) jeweils zwei Halbbehälter weisen eine zu einer der Ringspannflächen passende Anlagefläche und einen konischen Bodenteil auf.
This object is achieved according to the invention by the following features:
  • a) the axis of rotation carries a ring;
  • b) the ring has two ring clamping surfaces with clamping devices on its end faces;
  • c) a shut-off plate filling the inner cross section of the ring is arranged so as to be pivotable about an axis;
  • d) two half-containers each have a contact surface matching one of the ring clamping surfaces and a conical base part.

Die Erfindung sieht somit zwei gesonderte, und einzeln handhabbare Halbbehälter vor. Diese haben eine große offene Oberseite, so daß dieselben leicht zu beschicken sind. Die Halbbehälter lassen sich mit einfachen Transportvorrichtungen in den Ring des Drehmischers einsetzen. Sobald die Halbbehälter zusammengesetzt sind, kann der Mischvorgang in bekannter Weise durch Drehung des Doppelkonus-Mischbehälters durchgeführt werden. Nach Abschluß des Mischvorganges werden die Halbbehälter einzeln abgenommen und einer weiteren Verwendung zugeführt.The invention thus provides two separate and individually manageable half containers. These have a large open top so that they are easy to load. The semi-containers can be inserted into the ring of the rotary mixer with simple transport devices. As soon as the half-containers are assembled, the mixing process can be carried out in a known manner by rotating the double-cone mixing container. After the mixing process has been completed, the half-containers are removed individually and used for further use.

Die Zerlegung des Doppelkonusbehälters in zwei unabhängig von der Drehvorrichtung transportable Einzelbehälter mit Bodenauslaßöffnung bietet die Möglichkeit, diese Einzelbehälter als Transport-, Lager- und/oder Beschickungsbehälter zu verwenden, so daß diese dem Mischvorgang vor- oder nachgeschalteten Funktionen wesentlich rationalisiert werden. Die Einzelbehälter können auch als Arbeitsbehälter oder Beschickungsbehälter für nachfolgende Bearbeitungsstufen dienen.The disassembly of the double-cone container into two individual containers with a bottom outlet opening that can be transported independently of the rotating device offers the possibility of using these individual containers as transport, storage and / or loading containers, so that these functions upstream or downstream of the mixing process are substantially rationalized. The individual containers can also serve as work containers or feed containers for subsequent processing stages.

Da jeder Halbbehälter einen großen offenen Querschnitt an der Oberseite hat, läßt er sich bei Bedarf leicht reinigen. Außerdem kann man für unterschiedliches Mischgut gesonderte Halbbehälter bereithalten, SjO daß eine gegenseitige Verunreinigung verschiedener Chargen nicht zu befürchten ist. Die Erfindung ermöglicht damit eine überraschende Verbesserung des Reinigungsvorgangs und eine Erweiterung der Anwendbarkeit des Doppelkonus-Drehmischers durch Verwendung der Halbbehälter für die genannten Zwecke.Since each half container has a large open cross section at the top, it can be easily cleaned if necessary. In addition, separate half-containers can be kept ready for different mixes, so that mutual contamination of different batches is not to be feared. The invention thus enables a surprising improvement in the cleaning process and an expansion of the applicability of the double-cone rotary mixer by using the half-containers for the purposes mentioned.

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, clamping devices 8 and 8 'are provided, 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 Ringspannfläche7 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 a dispensing device 17, for example a closable dispensing opening. At the top there is a contact surface 18 which matches 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 In the manner shown in FIG. 4, clamp on the ring 6 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 abuts 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 auffüllt, 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 Schwenkwell 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 ist nicht möglich. 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 surface can be easily cleaned. The individual half-containers can each be used for similar batches of mixed material, so that cleaning is only required at longer intervals. For other mixes you can keep other half-containers ready, so that mixing or contamination of different batches can not. The stand 1 can also be designed such that it can be raised and lowered in order to be able to accommodate the half-containers.
