Description

Förderschnecke für Staubpumpen Die Förderschnecken für Staubpumpen, welche staubförmige Materialien, wie Zement; Kohlenstaub, Mehle usw., nach Zusatz eines gasförmigen Mittels durch geschlossene Förderleitungen drücken, werden meist @§o ausgebildet, daß das Gangvolumen nach dem Austrittsende zu abnimmt. Dies ist erforderlich, um eine gewisse Kompression des Fördermaterials zu erzielen. Von der Wahl des richrigen Volumenverhältnisses sind Förderleistung und Kraftverbrauch der Staubpumpe in weitem Maße abhängig.Screw conveyor for dust pumps The screw conveyor for dust pumps, what powdery materials, such as cement; Coal dust, flour, etc., as added Pressing a gaseous medium through closed delivery lines are mostly @ §O designed that the passage volume decreases after the exit end to. This is required to achieve a certain compression of the conveyed material. Of the The choice of the correct volume ratio is the delivery rate and power consumption of the Dependent on dust pump to a large extent.

Die Schnecken werden bisher so ausgebildet, daß der Kerndurchmesser nach dem Austrittsende stärker wird. Der günstigste Durchmesser ist jedoch in weiten Grenzen von der jeweiligen Beschaffenheit des Materials abhängig. Eine nachträgliche Änderung des Kerndurchmessers ist aber schwierig, da entweder Material aufgelegt oder abgenommen werden muß, was eklen Ausbau der Schnecke erforderlich macht.The screws are so far designed so that the core diameter becomes stronger after the exit. However, the cheapest diameter is wide Limits depend on the particular nature of the material. A subsequent one Changing the core diameter is difficult because either material is applied or has to be removed, which makes it necessary to remove the screw.

Vorliegende Erfindung vermeidet diese Nachteile. Die Abbildung zeigt ein Ausführungsbeispiel und stellt einen Schnitt durch das Austrittsende der Förderschnecke dar. Um den Schneckenkern a ist eine Schraubenflachfeder b gelegt, zwei Bolzen e' am Stirnende der Schraubenfeder b greifest in Schlitze d der um die Schneckenwelle drehbaren Scheibe e. Durch Drehen dieser Scheibe um die Schneckenwelle wird nun ein Zusammenziehen bzw. Aufweiten der Feder b erreicht, wodurch jeder Durchmesser leicht eingestellt werden kann. Bei größerer Länge des konischen Kernes wird die Feder durch verstellbare Distanzstücke i unterstützt.The present invention avoids these disadvantages. The figure shows an embodiment, and shows a section through the outlet end of the screw conveyor. In order to screw core A is placed a helical flat spring b, two bolts e 'at the front end of the coil spring b greifest in slots d of the rotatable around the screw shaft washer e. By turning this disk around the worm shaft, the spring b is now contracted or expanded, so that any diameter can be easily adjusted. If the conical core is longer, the spring is supported by adjustable spacers i.
