Description
Den Gegenstand der Erfindung bildet eine Maschine zum Putzen und Sortieren von Getreidekörnern, Getreide- und ähnlichen Produkten, die eine oder mehrere zylinderförmige Putz- und Sortiertrommeln aufweist.The subject of the invention is a machine for cleaning and sorting of cereal grains, cereal products and similar products that are one or more cylindrical Has cleaning and sorting drums.
Die Erfindung besteht gegenüber gleichartigen Maschinen darin, daß an und für sich bekannte Putz- und Sortiertrommeln nicht von innen mit dem zu reinigenden Gut gespeist werden, sondern daß das Gut auf die Außenwand einer Trommel aufgebracht wird, das obere seitliche Segment derselben durch einen Luftzwischenraum von einem Gittermantel umgeben ist und Luft durch diesen Gittermantel, das Gut und die Trommel hindurchgesaugt wird.The invention consists of similar machines in that cleaning and sorting drums known in and of themselves not with the inside to be cleaned Are fed well, but that the material is applied to the outer wall of a drum is, the upper lateral segment of the same through an air gap of one Mesh jacket is surrounded and air through this mesh jacket, the material and the drum is sucked through.
Die Trommel wird in der Fließrichtung des Gutes bewegt, wodurch sich die schweren Teile des Gutes durch die Zentrifugalkraft von der Trommel lösen, während die leichten Teile ,sowie der Staub infolge ihrer geringeren Zentrifugalkraft von der durchströmenden Luft auf die Trommel gepreßt bzw. durch diese hindurch aufgesaugt werden und die an der Trommel haftenden Teile durch eine Bürstenwalze in den Abfallkanal abgestreift werden.The drum is moved in the direction of flow of the material, causing it to move the heavy parts of the goods are loosened from the drum by centrifugal force, while the light parts, as well as the dust due to their lower centrifugal force of the air flowing through it is pressed onto the drum or sucked up through it and the parts adhering to the drum through a roller brush into the waste channel be stripped off.
Die angeführte Ausbildung des Erfindungsgegenstandes ergibt eine rasche und zuverlässige Reinigung des Gutes, wie sie mit Maschinen, bei denen das zu sortierende Gut in den Innenraum der Trommel geleitet, von umlaufenden Schlägern bearbeitet und von innen nach außen besaugt wird, nicht erreicht werden kann.The stated design of the subject matter of the invention results in a rapid one and reliable cleaning of the goods, as is the case with machines where that is to be sorted Well guided into the interior of the drum, processed by rotating bats and is sucked from the inside out, cannot be reached.
Die Zeichnung stellt den Erfindungsgegenstand in einem Ausführungsbeispiel dar.The drawing represents the subject matter of the invention in one embodiment represent.
Fig. i läßt einen Aufrißschnitt und Fig. z einen Grundriß bei abgenommener Oberseite mit Blick auf die Trommeln schematisch dargestellt, und zwar in Z-wvilddngsanordnurng, erkennen.Fig. I leaves a front elevation section and Fig. Z a plan view with the removed The top side with a view of the drums is shown schematically, in a Z-wigdngsanordnurng, recognize.
Arbeitsgang: Bei i tritt das zu sortierende Gut in die Maschine über eine Speiseklappe 2 ein, welche eine gleichmäßige Verteilung .des Gutes auf die ganze Breite der Trommel 3 bewirkt.Operation: At i, the goods to be sorted pass into the machine a feed flap 2, which ensures an even distribution of the goods on the entire width of the drum 3 causes.
Die Trommel 3, deren Bespannung aus Stahldrahtgewebe oder ähnlichen Geweben besteht, dreht sich in der Fließrichtung des Gutes. Zwischen der umlaufenden Trommel 3 und dem Außenmantel q. der Maschine, welcher im oberen Segment zwischen Einlaßwand 5 und Trommelebene mit Drahtgeweben oder ähnlichen Geweben bespannt und luftdurchlässig ist, wird ein Luftzwischenraum 6 gebildet. Das auf die rotierende Trommel 3 auffließende schwere Gut wird durch Zentrifugalkraft von derselben abgehoben, aufgelockert, während die durch den Mantel q. durch einen bei io angeschlossenen Ventilator angesaugte Luft durchströmt, die feinen bzw. leichten Teile an den Trommelmantel preßt bzw. durch die Trommel hindurch- und abzieht.The drum 3, its covering made of steel wire mesh or the like Consists of woven fabrics, rotates in the direction of flow of the goods. Between the encircling Drum 3 and the outer jacket q. of the machine, which is in the upper segment between Inlet wall 5 and drum level covered with wire mesh or similar fabrics and is air-permeable, an air gap 6 is formed. That on the rotating Drum 3 flowing heavy goods is lifted from the same by centrifugal force, loosened up, while the by the coat q. by one connected to io Air sucked in by the fan flows through the fine or light parts on the drum shell presses or pulls through the drum and pulls it off.
Die an der Trommel haftenden Teile werden durch eine rotierende Bürste 8 abgestreift und dem Abfallkanal g zugeführt, während das schwere, nunmehr gereinigte Gut bei 7 über Auslaufklappen abfließt. Sämtliche Auslaufkanäle können mit regelbaren Auslaufklappen oder umlaufenden Zellenwalzen, versehen, werden, wodurch die Einströmung von Falschluft verhindert wird.The parts sticking to the drum are cleaned by a rotating brush 8 stripped and fed to the waste channel g, while the heavy, now cleaned Flows well at 7 via outlet flaps. All outlet channels can be regulated with Outlet flaps or rotating cellular rollers, are provided, thereby preventing the inflow is prevented by air leakage.
