Description
geschleuderten Luftstrahlthrown air jet
Zusatz zum Patent 452Addendum to Patent 452
Nach dem Hauptpatent Nr. 452 306 ist' das Mischrohr für den Luft- und Gutstrom in LuftstrahlpraUzerkleinerern mit dem Gutauslaß des Zerkleinerungs- und Sichtbehälters durch eine Luftförderleitung verbunden. Diese Ausfiihrungsform hat den Nachteil, daß ein betriebsmäßiges Ansaugen des Gutes durch das Rohr hindurch eine unwirtschaftlich hohe Gebläseleistung erfordert.According to the main patent no. 452 306 is the mixing tube for the air and material flow in air jet shredders connected to the material outlet of the shredding and sifting container by an air supply line. This embodiment has the disadvantage that an operational suction of the material through the pipe results in an uneconomically high fan power requires.
Erfindungsgemäß- wird daher der Kreislauf des Gutes dadurch hergestellt, daß das im Zerkleinerungsbehälter
zu Boden fallende, noch nicht genügend zerkleinerte Gut durch ein mechanisches Fördermittel, beispielsweise eine
Schnecke, gehoben und dem Arbeitsluftstrahl entweder unmittelbar oder auf dem Umwege
über die Beschickungsvorrichtung wieder zugeführt wird.
Die Zeichnung veranschaulicht zwei Ausführungsformen der Erfindung.According to the invention, therefore, the cycle of the material is established in that the material that falls to the ground in the shredding container and has not yet been sufficiently shredded is lifted by a mechanical conveying means, for example a screw, and fed back to the working air jet either directly or indirectly via the loading device.
The drawing illustrates two embodiments of the invention.
Gemäß Abb. 1 läuft dem aus dem Druckrohr« austretenden Arbeitsluftstrahl einerseits das frische Gut aus dem Bunker g durch eine Beschickungsvorrichtung zu und wird durch das Mischrohr b hindurch gegen den Prallkörper c geschleudert und dadurch zerkleinert. Das fertige Feingut wird in bekannter Weise von der durch das Rohr d abziehenden Luft mitgenommen, während das noch nicht genügend zerkleinerte in den Trichter des Behälters e fällt und von einer mechanischen Fördervorrichtung, beispielsweise einer Schnecke, dem Luftstrahl von neuem zugeführt wird.According to Fig. 1, the fresh material from the bunker g flows into the working air jet emerging from the pressure pipe through a loading device and is thrown through the mixing pipe b against the impact body c and thereby comminuted. The finished fine material is entrained in a known manner by the air withdrawn through the pipe d , while the not yet sufficiently crushed falls into the funnel of the container e and is fed to the air jet again by a mechanical conveying device, for example a screw.
Wie punktiert angedeutet ist, kann der Bunker g wie bei dem Hauptpatent auch so angeordnet werden, daß das frische Gut nicht der Luftdüse, sondern dem Zerkleinerungsbehälter zuläuft, so daß die in dem frischen Gute enthaltenen feinen Teile sogleich abgeführt werden, ohne vorher den Zerkleinerungskreislauf zu durchlaufen.As indicated in dotted lines, the bunker g can also be arranged, as in the main patent, so that the fresh material does not run to the air nozzle but to the shredding container, so that the fine parts contained in the fresh goods are immediately removed without first having to go into the shredding circuit run through.
Bei der in Abb. 2 dargestellten Ausführungsform wird das im Behälter zu Boden fallende Gut durch eine Förderschnecke fa oder ein ähnliches Fördermittel in den Bunker g gehoben und von dort zusammen mit dem frischen Gute durch die Beschickungsvorrichtung dem Luftstrahl zugeführt.In the embodiment shown in Fig. 2, the material falling to the ground in the container is lifted into the bunker g by a screw conveyor f a or a similar conveying means and from there fed to the air jet together with the fresh material through the loading device.
