Gegenstand der vorliegenden Erfindung bildet eine Mischvorrichtung für körniges Material, insbesondere Formsand, mit einem oben offenen kreiszylindrischen Behälter, in welchem koaxial um eine lotrechte Achse ein Querhaupt umläuft, an welchem senkrecht dazu mindestens ein um eine horizontale Achse schwenkbarer Läufer angeordnet ist. The present invention provides a mixing device for granular material, in particular molding sand, with a circular cylindrical container open at the top, in which a crosshead rotates coaxially about a vertical axis and on which at least one rotor pivotable about a horizontal axis is arranged perpendicular thereto.
Bekannt ist beispielsweise eine Mischvorrichtung für körniges Material mit einem-oben offenen kreiszylindrischen Behälter, in welchem koaxial um eine lotrechte Achse ein Querhaupt umläuft, an welchem senkrecht dazu zwei um eine horizontale Achse schwenkbare Läufer und im Behälter umlaufende Pflüge angeordnet sind.For example, a mixing device for granular material with a circular cylindrical open top is known Container in which a crosshead rotates coaxially around a vertical axis, on which perpendicular to this, two rotors pivotable about a horizontal axis and rotating in the container Plows are arranged.
Mit einer Mischvorrichtung der vorbezeichneten Art wird das Mischgut, insbesondere Formsand, in der Weise vermischt, daß einmal durch die Läufer ein Brechen der sich bildenden Klumpen und ein Zerreiben des Formsandes erfolgt und daß zum anderen durch die Pflüge eine Mischung, Anhebung und ao Durchlüftung des Mischgutes bewerkstelligt wird.With a mixing device of the aforementioned type, the mix, in particular molding sand, is in mixed in such a way that once the runners break the lumps that have formed, they are ground up of the molding sand takes place and that on the other hand by the plows a mixture, raising and ao Ventilation of the mix is accomplished.
Um eine verbesserte Mischwirkung und insbesondere eine bessere Durchlüftung des Mischgutes bei Mischvorrichtungen der vorbezeichneten Art zu erhalten, ist nach neuen Mitteln und Wegen gesucht worden.In order to achieve an improved mixing effect and, in particular, better aeration of the material to be mixed To obtain mixing devices of the aforementioned type, new means and ways are being sought been.
■ Es liegt der Erfindung die Aufgabe zugrunde, eine Mischvorrichtung zu schaffen mit welchen gegenüber den bekannten Mischvorrichtungen der vorbeschriebenen Art eine bessere Durchlüftung als bisher er-,zielbar ist.■ The invention is based on the object of creating a mixing device with which opposite the known mixing devices of the type described above achieve better aeration than before, achievable is.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß mindestens auf einer der beiden Stirnseiten des Läufers schräg nach außen gerichtete Stifte angeordnet sind, derart, daß deren Achsen mit der Achse des Läufers einen spitzen Winkel einschließen.According to the invention the object is achieved in that at least one of the two end faces of the rotor obliquely outwardly directed pins are arranged, such that their axes with the axis of the runner include an acute angle.

Anmelder:In Fig. 1 shows a mixing device 10 with an upright circular-cylindrical container 12, in the center of which a crosshead 20 is arranged to be rotatable about the vertical axis 22. The direction of rotation of the crosshead is indicated by arrow 24. Attached to the crosshead 20 are arms 26 and 28 which have an outer paddle 30 and an inner paddle 32 mixing device for granular material

tragen. Die unteren Kanten der Schaufeln 30 und 32 befinden sich in unmittelbarer Nähe der Grundplatte 16, um das körnige Material zu bewegen und zu mischen und gleichzeitig eine Anhäufung desselben zu verhindern. Die äußere Kante der Schaufel 30 bewegt sich in unmittelbarer Nähe der zylindrischen Innenwand des Behälters 12. Die Schaufel 30 ist derart gekrümmt, daß das körnige Material vom Umfang der Grundplatte 16 nach innen in die Laufbahn der Läufer bewegt wird, solange das Querhaupt 20 sich dreht. Die innere Kante der Schaufel 32 bewegt sich in der Nähe des Zentrums des Behälters 12. Die Schaufel 32 ist derart gekrümmt, daß das körnige Material aus der Mitte des Behälters 12 nach außen unter die Laufbahn der Läufer geschoben wird.wear. The lower edges of the blades 30 and 32 are in close proximity to the base plate 16 to move and mix the granular material and at the same time to accumulate it impede. The outer edge of the blade 30 moves in close proximity to the inner cylindrical wall of the container 12. The paddle 30 is curved so that the granular material from the periphery of the Base plate 16 is moved inwardly into the raceway of the runner as long as the crosshead 20 is rotating. The inner edge of the scoop 32 moves near the center of the container 12. The scoop 32 is curved so that the granular material from the center of the container 12 outwards under the raceway the runner is pushed.
Am Querhaupt 20 sind Träger 34 um horizontale Achsen beweglich angebracht. Die Träger 34 stehen üblicherweise senkrecht zu den Armen 26 und 28. Jeder Träger 34 ist mit einer Achse 36 versehen, auf welcher ein Läufer 38 drehbar gelagert ist. Sobald das Querhaupt 20 sich dreht, werden die Läufer 38 durch Reibung mit dem eingefüllten körnigen Material in Richtung der Pfeile 40 (F i g. 2 und 3) in Umdrehung versetzt.Carriers 34 are attached to crosshead 20 so as to be movable about horizontal axes. The carriers 34 are usually perpendicular to the arms 26 and 28. Each carrier 34 is provided with an axis 36 on which a rotor 38 is rotatably mounted. As soon as the crosshead 20 rotates, the runners 38 are set in rotation in the direction of the arrows 40 (FIGS. 2 and 3) by friction with the granular material filled in.
Die Läufer 38 sind zweckmäßigerweise aus einem schweren Werkstoff hergestellt, beispielsweise aus Gußeisen oder Stahl. Die Läufer 38 haben an ihrem Umfang eine kreiszylindrische Lauffläche 42, durch welche das eingefüllte körnige Material zerkleinert wird. Auch Klumpen von Formsand, die aus derThe runners 38 are expediently made from a heavy material, for example from Cast iron or steel. The runners 38 have a circular cylindrical running surface 42 on their circumference which the filled granular material is crushed. Also lumps of molding sand that came out of the
