KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Zum Sieben von Kohlen, Koks und dergleichen Massen werden sog. Kreiselrätter verwendet, bei denen die Siebe entweder Kreisbewegungen in wagerechter Ebene oder Bewegungen im Raum Kurven höherer Ordnung ausführen, die sich aus kreisender und gleichzeitig auf und ab schwingender Bewegung zusammensetzen. Das hierdurch gut ausgebreitete Siebgut gleitet dabei krummlinig überSo-called gyroscopes are used to sieve coal, coke and similar masses. in which the sieves either make circular movements in a horizontal plane or movements execute higher-order curves in space, which result from circling and simultaneous Assemble up and down swinging motion. That which is well spread out as a result The material to be screened glides over in a curvilinear manner
ίο die Siebflächen. Zu letzterer Gattung gehört auch der Erfindungsgegenstand.ίο the sieve surfaces. Belongs to the latter genus also the subject of the invention.
Ist das Siebgut feucht, so sind die gröberen Stücke desselben auch nach der Klassierung noch mit feinem Grus behaftet. Dieser feine Grus setzt sich in den Sieblochungen fest, so daß diese verkleinert, wenn nicht ganz geschlossen werden.If the material to be screened is moist, the coarser pieces of it are also after classification still afflicted with fine grief. This fine grit gets stuck in the screen perforations, see above that these are reduced in size, if not completely closed.
Die Erfindung bezweckt nun, die Siebe der Rätter neben der bekannten wagerechten Kreisbewegung fortgesetzt Erschütterungen in senkrechter Richtung auszusetzen, damit einesteils der feuchte Grus von den Lochwandungen entfernt wird und andernteils durch die Erschütterungen die gröberen Stücke von dem Grus befreit werden.The invention now aims at the sieves of the ratters in addition to the known horizontal circular movement continued to be exposed to vibrations in the vertical direction, thus on the one hand the damp gravel is removed from the hole walls and partly by the vibrations the coarser pieces are freed from the gravel.
Zu diesem Zweck bestehen die Siebkästen aus zwei Teilen: dem äußeren Antriebsrahmen a, welcher nur die wagerechte Kreisbewegung, und dem inneren eigentlichen Siebrahmen b, der die Kombinationsbewegung, zusammengesetzt aus wagerechter Kreisbewegung und senkrecht auf- und abwärts gerichteter Bewegung, ausführt. Der äußere Rahmen läuft in bekannter Weise auf vier Kugelpfannenlagern c und wird, wie schon vielfach ausgeführt, durch zwei senkrechte Kurbelachsen d angetrieben. Der innere Siebrahmen aber ist einerseits mit dem Antriebsrahmen in senkrechter Richtung beweglich, durch wagerecht liegende Scharniere oder Federn e verbunden, anderseits mittels Kugelgelenk mit der gleichen Exzentrizität wie die der Antriebskurbelachsen auf die obere Hälfte eines oder zweier Pfannenlager f gestützt, deren beide Hälften schraubenförmige Tragflächen besitzen, welche bewirken, daß durch die gemeinsame Drehbewegung beider Rahmen der innere Siebrahmen bei jeder Umdrehung unabhängig vom Antriebsrahmen ein oder mehrere Male langsam gehoben wird und rasch in seine tiefste Lage zurückschnellt, dadurch also fortgesetzten Erschütterungen ausgesetzt ist.For this purpose, the sieve boxes consist of two parts: the outer drive frame a, which only performs the horizontal circular movement, and the inner actual sieve frame b, which carries out the combined movement, composed of horizontal circular movement and vertical up and down movement. The outer frame runs in a known manner on four ball socket bearings c and, as already stated many times, is driven by two vertical crank axles d. The inner screen frame, however, is on the one hand movable with the drive frame in a vertical direction, connected by horizontally lying hinges or springs e , on the other hand supported by a ball joint with the same eccentricity as that of the drive crank axles on the upper half of one or two socket bearings f , both halves of which are helical bearing surfaces which have the effect that by the common rotary movement of both frames the inner screen frame is slowly lifted one or more times with each rotation independently of the drive frame and quickly snaps back into its lowest position, thus being exposed to continued vibrations.
