Abstract

Die Erfindung bezieht sich auf ein Verfahren und eine Einrichtung zur Steuerung des Fluidpulveraustritts aus einem Behälter. Sie läßt sich anwenden zur Steuerung des Pulverausstoßes aus einer Pulversprüheinrichtung zum elektrostatischen Lackieren.
Mit der Erfindung wird vorgeschlagen, die Nachteile einer mechanischen Schließeinrichtung zu vermeiden durch Einleitung einer Schließluft (LS) in ein Entnahmerohr (25) für die Entnahme fluidisierten Pulvers (8) aus einem Behälter (2). Die Einleitung der Schließluft (LS) erfolgt über ein Rohr (51), das in eine Öffnung (50) am Mantel des Entnahmerohrs (25) mündet. Der Massenstrom des fluidisierten Pulvers kann durch entsprechende Einstellung eines Druckes (pR) im Entnahmerohr (25) im Verhältnis zum Druck (p3) im Fluidbett, d. h. durch Einleitung von Schließluft (LS) mit entsprechendem Druck gesteuert werden.
