Description

Windsichter mit einem über der Mündung des Staubluftrohres angebrachten Prallschirm mit gekrümmter Unterfläche. Die Erfindung bezieht sich auf Windsichter, in denen über der Mündung des Staubluftröhres ein Prallschirm angebracht ist, dessen Unterfläche zur Erzielung einer Umkehrung des Staubluftstromes gekrümmt ist. Die Erfindung besteht darin, daß auf dieser der Mündung des Staubluftrohres. zugekehrten Seite des Prallschirmes beliebig gestaltete Leitschaufeln vorgesehen sind, zum Zweck, das Sichtgut in Drehung zu versetzen und ihm außer dem Richtungswechsel noch einen verlängerten Sichtweg zu geben. Dadurch ergeben sich die Vorteile einer kleineren Größenbemessung des Sichters. ohne Anwendung sich drehender Teile und somit Erzielung einer beträchtlichen Kraftersparnis.Wind sifter with a mounted above the mouth of the dust air pipe Impact parachute with a curved lower surface. The invention relates to air separators, in which a baffle screen is attached over the mouth of the dust air tube, its The lower surface is curved to achieve a reversal of the dust air flow. the Invention is that on this the mouth of the dust air tube. facing Side of the impact screen, guide vanes of any shape are provided for the purpose of to set the material to be viewed in rotation and, in addition to the change of direction, to give it another to give an extended visual path. This gives the advantages of a smaller one Sizing the sifter. without using rotating parts and thus achieving a considerable energy saving.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel in Abb. i im Längsschnitt und in ' Abb. 2 in Oberansicht dargestellt.In the drawing, the invention is shown in one embodiment in Fig. I in longitudinal section and in 'Fig. 2 in top view.

In das Sichtergehäuse d mündet von unten kommend das Staubluftrohr b, über dem in gewissem Abstande der Prallschirm c angeordnet ist. Dieser Prallschirm c besitzt an seiner unteren, dem Staubluftrohr b zugekehrten Seite, und zwar in der Horizontalrichtung gekrümmte, feststehende Leitschaufeln d, die verschiedenartig gekrümmt sein können, z. B. nach Art eines Propellers., einer Spirale, einer feststehenden Schnecke o. dgl.The dust air pipe, coming from below, opens into the separator housing d b, above which the impact screen c is arranged at a certain distance. This impact screen c has on its lower side facing the dust air tube b, namely in the horizontal direction curved, fixed guide vanes d, the various can be curved, e.g. B. in the manner of a propeller., A spiral, a fixed Snail or the like

Das bei b in den Sichter a eintretende, in bekannter Weise durch einen Exhaustor angesaugte Sichtgut wird gegen den Prallschirm c geschleudert. Hier wird es gezwungen, an den gekrümmten Leitflächen d entlang, also in der Pfeilrichtung in Abb.2, zu gleiten. Es wird ihm also neben dem Richtungswechsel ein verlängerter Sichtungsweg erteilt.The material to be classified, which enters the classifier a at b and is sucked in in a known manner through an exhaustor, is hurled against the baffle screen c. Here it is forced to slide along the curved guide surfaces d, i.e. in the direction of the arrow in Figure 2. In addition to the change of direction, he is given an extended sighting path.
