Description

Druckwindsichter mit zwei konzentrisch ineinandersitzenden zylindrischen Gehäusen Gegenstand der Erfindung ist ein Druckwindsichter mit Nachreinigung der Grieße im Druckwindstrom.Pressure air classifier with two concentric cylindrical ones Housing The subject of the invention is a pressure air classifier with post-cleaning Semolina in the pressure wind stream.

In bekannter Weise wird durch einen Exhaustor Sichtluft und Sichtgut in den Sichtraum eingeführt. Das Feingut steigt mit der Sichtluft spiralenförmig hoch und tritt in den innen befindlichen Feingutraum über, während die Sichtluft zum Exhaustor zurückkehrt. Ein zweiter Exhaustor drückt die Luft in den unten am Sichtergehäuse befindlichen Grießauslauf, bläst das an den herabfallenden Grießen noch anhaftende Feingrit ab und führt es wieder in den Sichtraum.In a known manner, class air and class material are generated by an exhaustor introduced into the viewing space. The fine material rises in a spiral with the sifting air high and passes into the interior fine material room, while the sifting air returns to the exhaustor. A second exhaustor pushes the air into the bottom of the Sifter housing located semolina outlet, blows on the falling semolina still adhering fine grit and leads it back into the viewing area.

Abb. i stellt einen Längsschnitt durch den Sichter dar, Abb. z die Seitenansicht von Abb. i. In das zylindrische Außengehäuse i, das unten kegelförmig zuläuft und oben mit einem Deckel abgeschlossen ist, ist das zylindrische und unten ebenfalls kegelförmig zulaufende Innengehäuse :2 eingepaßt. Der Kegel des Innengehäuses z mündet in den Auslaufstutzen für das Feingut. In den Kegel des Außengehäuses i mündet tangential der Druckstutzen 3 des Exhaustors 6. Unter dem Kegel des Außengehäuses i befindet sich der Raum 4 zur Nachreinigung der Grieße. In diesen Raum 4 ragt der Druckstutzen des Exhaustors 7 hinein, während das untere Ende des Raumes 4 als Grießauslauf ausgebildet ist. Auf dem Deckel des Außengehäuses i ist das Saugrohr 5 aufgeschraubt, von welchem die Saugleitungen der Exhaustoren 6 und 7 abzweigen. Am Saugstutzen des Exhaustors 6 befindet sich der Sichtguteinlauf a.Fig. I shows a longitudinal section through the classifier, Fig. Z the Side view of Fig. I. In the cylindrical outer housing i, which is conical at the bottom runs in and is closed with a lid at the top, that is cylindrical and at the bottom also tapered inner housing: 2 fitted. The cone of the inner casing z opens into the outlet nozzle for the fine material. In the cone of the outer housing i The pressure port 3 of the exhaustor 6 opens out tangentially under the cone of the outer housing i is the room 4 for post-cleaning of the grits. In this room 4 protrudes Pressure port of the exhaustor 7 into it, while the lower end of the space 4 as a semolina outlet is trained. The suction tube 5 is screwed onto the cover of the outer housing i, from which the suction lines of the exhaustors 6 and 7 branch off. At the suction port of the exhaustor 6 is the classifying material inlet a.

Bringt man Sichtgut in den Einlauf d, so wird es vom Exhaustor 6 angesaugt und tan--ential in den Kegel des Außengehäuses eingeblasen. Luft und. Sichtgut kreisen im Außengehäuse und steigen unter dem Einfluß der durch den Grießreinigungsraufn 4 in den Außenkegel eintretenden Luft des Exhaustors 7 nach oben. Die Fliehkraft trägt die Grieße an die Wandung von Außenzylinder und Außenkegel, wo sie herabgleiten und in den Grießreinigungsraum 4 gelangen. Hier werden die Grieße einer Nachreinigung durch den vom Exhaustor 7 in den Grießreinigungsraum eintretenden Druckluftstrom unterzogen, welcher das an den Grießen noch anhaftende Feingut abbläst und wieder in den Außenkegel und Sichtraum führt.If material to be classified is brought into the inlet d, it is sucked in by the exhaustor 6 and tan - entially blown into the cone of the outer casing. Air and. Circling visible goods in the outer casing and rise under the influence of the semolina cleaning racks 4 air of the exhaustor 7 entering the outer cone upwards. The centrifugal force carries the grits to the wall of the outer cylinder and outer cone, where they slide down and get into the semolina cleaning room 4. Here are the grits of a post-cleaning by the compressed air flow entering the semolina cleaning room from the exhaustor 7 subjected, which blows off the fine material still adhering to the semolina and again leads into the outer cone and viewing area.

Die gereinigten Grieße treten durch den Grießauslaufstutzen aus. Das Feingut steigt mit der Luft im Außenzylinder nach oben, gelangt in den Innenzylinder und Innenkegel und tritt durch den Feingutstutzen aus. Die Luft und ein Teil des Feinstaubes kehren durch das Saugrohr 5 und die beiden Saugrohrleitungen in die beiden Exhaustoren 6 und 7 zurück.The cleaned grits emerge through the grit outlet nozzle. That Fine material rises with the air in the outer cylinder and reaches the inner cylinder and inner cone and exits through the fine material nozzle. The air and part of the Fine dust sweeps through the suction pipe 5 and the two suction pipes into the both exhaustors 6 and 7 back.
