Description

Luftsichter, bei dem das durch den Ventilator aus dem Aufgabegut abgesaugte Feingut zwischen zwei Rundwänden hindurchgesaugt wird. Die Erfindung betrifft einen Luftsiahter, bei dem das durch den Ventilator aus dem Aufgabegut abgesaugte Feingut zwischen zwei Rundwänden hindurchgesaugt und in den Feingutraum geblasen wird. Nach der Erfindung sind die Rundwände in der Weise im Querschnitt zickzackförrnig gestaltet, daß der aufsteigende Luftstrom zu einer mehrfachen Änderung seiner Richtung gezwungen wird. Der achsiale Abstand der beiden Rundwände voneinander ist einstellbar.Air sifter, in which the material is sucked out of the feed material by the fan Fine material is sucked through between two round walls. The invention relates to a Air sealer, in which the fine material sucked out of the feed material by the fan is sucked through between two round walls and blown into the fine material space. To According to the invention, the round walls are designed with a zigzag shape in cross-section, that the ascending air flow is forced to change its direction several times will. The axial distance between the two round walls is adjustable.

Da der aufsteigende Luftstrom durch die im Querschnitt zickzackförmigen Wände hindurchgeführt wird, stoßen sich die von dem Luftstrom mitgerissenen feinen Körnchen an den Wänden und fallen herunter, so daß das in dem Luftstrom befindliche Feingut ausgeschieden wird und der Luftstrom beim Eintritt in den Ventilator möglichst von Gutteilchen frei ist. Die Einstellbarkeit des achsialen Abstandes der Rundwände gestattet die Änderung des Durchgangsquerschnittes und der Strömungsgeschwindigkeit.Since the rising air flow through the zigzag in cross-section Walls is passed through, the fine carried by the air flow push each other Grains on the walls and fall down so that that is in the air stream Fine material is excreted and the air flow as possible when entering the fan is free of good particles. The adjustability of the axial distance between the circular walls allows the passage cross-section and the flow velocity to be changed.

Die Zeichnung veranschaulicht schematisch ein Ausführungsbeispiel der Erfindung. Vermittels des von der Welle W gedrehten Streutellers T wird das durch den Einlauftrichter E eingeführte Sichtgut gegen den Anwurfring A und dadurch in den Sichtraum R geschleudert. Mit Hilfe des ebenfalls von der Welle W umgedrehten Ventilators V, der mittels der Mitnehmer X vom Streuteller T mitgenommen wird, wird das Mehl aus dem Sichtraum R durch den Raum R1 gesaugt. Den Raum R1 bilden zwei Rundwände Z und Zl, die im Querschnitt zickzackförmig gestaltet sind. Die Rundwand Z1 ist in achsialer Richtung gegenüber der feststehenden Wand Z verschiebbar angeordnet, und durch Verschiebung der Wand wird der Durchgangsquerschnitt geändert. Der Ventilator verursacht einen im Sinne der Pfeile P kreisenden Luftstrom.The drawing schematically illustrates an embodiment of the invention. By means of the spreading plate T rotated by the shaft W, the material introduced through the inlet funnel E is thrown against the throwing ring A and thereby into the classifying space R. With the help of the fan V, which is also turned by the shaft W and which is carried along by the spreading plate T by means of the drivers X , the flour is sucked from the classifying space R through the space R1. The space R1 is formed by two round walls Z and Zl, which are designed in a zigzag shape in cross section. The round wall Z1 is arranged to be displaceable in the axial direction with respect to the stationary wall Z, and the passage cross section is changed by moving the wall. The fan causes an air flow circulating in the direction of the arrows P.
