Description
Dia Erfindung betrifft eine schnell laufende Siebmaschine, insbesondere eine Vibrationsmaschine für Feinsiebung, mit nach oben oder unten gewölbter Siebfläche. Siebmaschinen mit gewölbter Siebfläche sind nicht mehr neu, doch verläuft bei den bekannten Maschinen die Wölbung entweder in der Spannrichtung der Siebe, oder das Siebgewebe ist auf Rahmen, Bändern, Federn od. dgl. befestigt, ohne daß eine bestimmte Spannrichtung vorherrscht. Demgegenüber ist die Siebmaschine nach 'der Erfindung dadurch gekennzeichnet, daß das nur in einer Richtung gespannte und im übrigen frei liegendte Sieb quer zur Spannsichtung gewölbt ist. Diese Anordnung hat neben einer einfachen Spannmöglichkeit sowie der bequemen Verwendung von Sieben, die breiter als lang sind (d: h. deren Ausdehnung in der Laufrichtung des Siebgutes kürzer ist als. senkrecht dazu), den großen Vorteil, daß die Spannung ganz unabhängig von der Art der Wölbung gewählt werden kann. Bei Benutzung von an sich bekannten, in einigem Abstand von der Siebfläche endigenden Stützträgern zur Begrenzung des Flatterns des Siebes können diese Stützträger ohne - weiteres ebenfalls quer zur Spannrichtung angeordnet sein, wodurch ihnen ohne Störung der. Siebarbeit größere Ausdehnung gegeben werden kann. Es ist auch noch zu erwähnen, daß die Neigung der Wölbungstangente gegen die Horizontale an den beiden Enden des Siebquerschnittes verschieden gewählt' werden kann, was in Verbindung mit am Aufgabe- und Ablaufende der Maschine verschiedenen Schwingungsformen große siebtechnische Vorteile bringt, insbesondere bei einer Form des Siebes, das breiter als lang ist.The invention relates to a high speed screening machine, in particular a vibration machine for fine sieving, with a sieve surface curved upwards or downwards. Sieving machines with a curved sieve surface are no longer new, but the process runs smoothly with the known machines the curvature either in the tensioning direction of the sieves, or that Screen fabric is od on frames, ribbons, springs. Like. Fixed without a specific Direction of tension prevails. In contrast, the screening machine is according to the invention characterized in that the tensioned only in one direction and otherwise free lying sieve is arched transversely to the tension sifting. This arrangement has next to one easy clamping and the convenient use of sieves that are wider than are long (i.e. their extension in the direction of travel of the material to be screened is shorter as. perpendicular to it), the great advantage that the voltage is completely independent of the Type of bulge can be chosen. When using per se known, in some Distance from the support beams ending at the screen surface to limit the flutter of the sieve, these support beams can easily - also transversely to the clamping direction be arranged, giving them without disturbing the. Siebararbeit given greater expansion can be. It should also be mentioned that the inclination of the tangent of the arch Chosen differently against the horizontal at the two ends of the screen cross-section ' what can be different in connection with at the end of the task and at the end of the process of the machine Wave forms brings great advantages in terms of screening technology, especially with one form of the sieve, which is wider than it is long.
In der Zeichnung ist eine Ausführungsform der Erfindung schematisch dargestellt. Das Sieb i ist in Richtung der Pfeile 2 in der Siebmaschine eingespannt, wobei die Spannstellen so angeordnet sind, daß sich eine nach oben konvexe Wölbung des Siebes quer zur Spannrichtung ergibt: Zur Begrenzung des Siebflatterns sind Trägerstützen 3 vorgesehen, die in einem Abstand 4 von der Siebfläche enden, so daß das Sieb im Ruhezustand freiliegt. Die Aufgaberichtung liegt quer zur Spannrichtung, weshalb die Trägerstützen 3 kein Hindernis bilden und demgemäß (wie dargestellt) über die ganze Siebfläche reichen können; sie können aber auch auf einzelne Stellen beschränkt werden.An embodiment of the invention is shown schematically in the drawing shown. The sieve i is clamped in the sieving machine in the direction of arrows 2, wherein the clamping points are arranged so that an upwardly convex curvature of the sieve transversely to the tensioning direction results in: To limit the sieve flutter are Carrier supports 3 are provided, which end at a distance 4 from the screen surface, so that the sieve is exposed at rest. The feed direction is perpendicular to the clamping direction, which is why the girder supports 3 do not form an obstacle and accordingly (as shown) can extend over the entire sieve surface; but they can also be applied to individual positions be restricted.
je nach den Bedürfnissen können. die Trägerstützen über und unter dem Sieb einander gegenüber oder (wie dargestellt) auf Lücke stehen. Der Neigungswinkel der Wölbungskontur gegen die Horizontale ist im dargestellten Beispiel an beiden Siebenden als gleich angenommen, kann aber auch aus den bereits erwähnten -Gründen verschieden gewählt werden..depending on the needs can. the beam supports above and below facing each other or (as shown) with a gap. The angle of inclination the curvature contour against the horizontal is in the example shown on both Sevens assumed to be the same, but can also be for the reasons already mentioned can be chosen differently.
