Abstract

An apparatus is proposed for mixing and processing free-flowing materials, especially moulding sand, having a cylindrical mixing vessel (1), the mixing vessel (1) including its bottom and cover being arranged so as to be stationary and one or more rotating whirler shafts (7) are provided which revolve in the vessel on a circular trajectory. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Mischen und Aufbereiten von rieselfähigen Materialien, insbesondere mit einem zylindrischen Mischbehälter.The invention relates to a device for mixing and processing free-flowing materials, in particular with a cylindrical mixing container.

Es sind Mischer bekannt, bei denen Schleuderwellen und Mischarme vorgesehen sind, die jedoch nicht umlaufen, sondern ortsfest angeordnet sind. Um das Mischgut dem Mischwerkzeugen zuzuführen, werden dabei entweder

  • a) der Mischerboden in Drehung versetzt, was erheblische Probleme bei der Abdichtung des rotierenden Mischerbodens
    gegen die stationäre Mischerwand mit sich bringt, wobei auch die Anordnung der Entleerungsklappen bei dieser Ausführung problematisch ist, oder
  • b) der ganze Mischerbehälter in Drehung versetzt bei ortsfester Anordnugn der Mischwerkzeuge. Diese Variante ist insbesondere aus der DE-OS 33 12 869 A1 bekannt.
Mixers are known in which centrifugal shafts and mixing arms are provided, but which do not rotate, but are arranged in a stationary manner. To feed the mix to the mixing tools, either
  • a) the mixer base rotates, which causes significant problems in sealing the rotating mixer base
    brings against the stationary mixer wall, the arrangement of the emptying flaps is problematic in this embodiment, or
  • b) the entire mixer container rotates when the mixing tools are arranged in a fixed position. This variant is known in particular from DE-OS 33 12 869 A1.

Auch diese Lösung erfordert jedoche einen komplizierten und störanfälligen Aufbau bezüglich der Entleerungsklappe und der Abdichtung des Misch-Oberteils gegen den rotierenden Mischbehälters.However, this solution also requires a complicated and fault-prone structure with regard to the emptying flap and the sealing of the mixing upper part against the rotating mixing container.

Die vorliegende Erfindung hat es sich zu Aufgabe gemacht, die vorstehenden Nachteile zu vermeiden und einen Mischer zu schaffen, der einfach im Aufbau, preisgünstig in der Herstellung und problemlos im Betrieb ist. Gleichzeitig soll durch das Zusammenwirken der umlaufenden Pfluges 9 mit der ebenfalls umlaufenden rotierenden Schleuderwelle ein optimales Druckmischen des Mischgutes erzielt werden.The present invention has set itself the task of avoiding the above disadvantages and to provide a mixer that is simple in construction, inexpensive to manufacture and easy to operate. At the same time, an optimal pressure mixing of the material to be mixed should be achieved by the interaction of the rotating plow 9 with the rotating rotating centrifugal shaft.

Diese Aufgabe wird dadurch erreicht, dass der Mischbehälter 1 einschliessliche dessen Boden und Deckel stationär angeordnet sind und dass eine oder mehrere rotierende Schleuderwellen 7 vorgesehen sind, die in dem Behälter auf einer Kreisbahn umlaufen.This object is achieved in that the mixing container 1, including the bottom and cover thereof, are arranged in a stationary manner and in that one or more rotating centrifugal shafts 7 are provided which rotate in a circular path in the container.

Anhand der beigelegten Figur wird die Erfindung näher beschrieben.The invention is described in more detail with reference to the attached figure.

Um die Mittelachse läuft, angetrieben durch ein Getriebe 4 und einem Motor 5, ein Getriebe 6 mit einer Schleuder-Welle 7 um. Mit dieser Drehbewegung ist der Welle 8 ein Pflug 9 gekoppelt.A gear 6 with a centrifugal shaft 7 rotates around the central axis, driven by a gear 4 and a motor 5. A plow 9 is coupled to the shaft 8 with this rotary movement.

Die Schleuderwelle 7 wird von einem Motor 10 über das Getriebe 6 in schnelle Drehung versetzt.The centrifugal shaft 7 is set in rapid rotation by a motor 10 via the gear 6.
