Description

Umlaufendes Hingtellersieb. Die vorliegende Siebvorrichtung besteht aus zwei konzentrischen ringförmigen Sieben a und b, die sich in entgegengesetzter Richtung drehen, und zwar das äußere a langsamer als das innere b. Ein gewöhnliches drehbares Tellersieb verfehlt insofern seine Wirkung, als die nach außen zunehmende Zentrifugalkraft bald so groß wird, daß die Vorrichtung zu einer Schleuder ohne Siebwirkung wird. Daher ist die obenerwähnte Trennung der Siebfläche in zwei Ringsiebe vorgenommen. Die Drehzahl der beiden Ringe ist dem jeweiligen Siebgut angepaßt und kann bei wechselnder Klebrigkeit evtl. elektrisch reguliert werden. Das Siebgut fällt durch einen Trichter c zunächst auf den inneren Siebring und wird hier bereits in der Hauptsache abgesiebt, während der Rest durch die Zentrifugalkraft nach außen abgeschoben wird und gegen eine ringsherum angebrachte Spritzwand d fliegt. Von hier aus fällt das Siebgut auf das tiefer liegende äußere Sieb, das sich, wie gesagt, langsamer dreht. Die neue Fallgeschwindigkeit und die verlangsamte Drehzahl bewirken ein gehöriges Nachsieben. Das Siebfeine gelangt durch einen Trichter e in eine Abflußrinne, während das Siebgrobe durch einen konzentrischen, oben mit einer ringsherum gehenden Schutzwand versehenen Trichter f aufgefangen und gleichfalls zu einer Abflußrinne geführt wird. Kurz vor dem Abfalltrichter wird ein Besen g angebracht, der die Siebmaschen rein hält.Circumferential hanging plate sieve. The present screening device consists from two concentric ring-shaped sieves a and b, which are in opposite directions Turn direction, the outer a slower than the inner b. An ordinary one rotatable plate sieve fails to have its effect insofar as the outwardly increasing Centrifugal force soon becomes so great that the device becomes a sling without Sieving effect is. Therefore, the aforementioned separation of the sieve surface into two ring sieves performed. The speed of the two rings is adapted to the material being screened and can possibly be regulated electrically if the stickiness changes. The screenings falls through a funnel c first onto the inner sieve ring and is already here Mainly screened out, while the rest outwards through centrifugal force is pushed off and flies against a firewall d attached around it. from from here the material to be sieved falls onto the lower-lying outer sieve, which, as I said, is turns slower. Effect the new rate of fall and the slowed speed a good sifting. The fine sieve passes through a funnel e into a drainage channel, while the sieve coarse through a concentric, above with a going around Protective wall provided funnel f and also to a drainage channel to be led. Shortly in front of the waste funnel, a broom g is attached to the sieve mesh keeps pure.

PATENTANSPRÜCHE: i. Umlaufendes Ringtellersieb, gekennzeichnet durch Unterteilung der Siebfläche in zwei getrennte, in radialer Richtung aneinander anschließende Siebringe, von denen der äußere, mit geringerer Winkelgeschwindigkeit umlaufend als der innere, den vorgesiebten Übertrag desselben nachsieht. a. Vorrichtung nach Anspruch i, dadurch gekennzeichnet, daß das äußere Ringsieb tiefer liegt als das innere zur Ausnutzung einer neu erzielten Fallgeschwindigkeit für den Siebzweck. 3. Vorrichtung nach Anspruch i und z, dadurch gekennzeichnet, daß um das innere Ringsieb herum eine Spritzwand angebracht ist. q.. Vorrichtung nach Anspruch i, dadurch gekennzeichnet, daß die Drehzahl der Ringsiebe evtl. auf elektrischem Wege den Erfordernissen des jeweiligen Siebgutes angepaßt werden kann. PATENT CLAIMS: i. Circulating ring plate sieve, characterized by the subdivision of the sieve surface into two separate sieve rings adjoining each other in the radial direction, of which the outer one, revolving at a lower angular speed than the inner one, looks for the pre-screened transfer of the same. a. Device according to claim i, characterized in that the outer ring sieve is lower than the inner one in order to utilize a newly achieved falling speed for the sieving purpose. 3. Apparatus according to claim i and z, characterized in that a bulkhead is attached to the inner ring sieve. q .. Device according to claim i, characterized in that the speed of the ring sieves can possibly be adapted electrically to the requirements of the respective material to be sieved.
