Description
DEUTSCHESGERMAN
Die Erfindung betrifft eine Schleudermühle mit einem am Grunde eines Gehäuses angeordneten, um eine lotrechte Achse umlaufenden Schleuderteller, dem das Zerkleinerungsgut von oben aufgegeben wird und der es nach außen über seinen Rand hinweg gegen die gegebenenfalls mit Rippen od. dgl. versehene Gehäusewand schleudert, an der es nach oben in den Bereich eines zentral oberhalb des Schleudertellers gelegenen Sichters geleitet wird, der die gröberen Teile wieder auf den Schleuderteller fallen läßt, und sie verfolgt das Ziel, eine höchstmögliche Absichtung des Feingutes mit einfachen Mitteln im Dauerbetrieb zu erreichen. Es sind derartige Mühlen seit langem bekannt, in denen die von dem austragenden Luftstrom durchstrichene Kammer über dem Schleuderteller angeordnet ist und das Grobe dann aus dem abziehenden Luftstrom niederfällt, um wieder auf den Schleuderteller zu gelangen, aber es hat sich gezeigt, daß damit allein noch keine Feinstsichtung erzielt wird, auch wenn man statt einer einzigen Austragkammer deren mehrere ineinander übergehende angeordnet hat. Auch daß man bei einer anderen Mühle dieser Art das über dem Schleuderteller vorgesehene Gehäuse konkav ausgerundet und mit einem weit nach innen hin gegen die Umlaufachse vorstehenden Innenrand versah, vermochte keinen ausreichenden Erfolg zu bringen.The invention relates to a centrifugal mill with a arranged at the bottom of a housing to a vertical axis rotating centrifugal plate, to which the material to be shredded is fed from above and which it outwards over its edge against the housing wall, which is optionally provided with ribs or the like centrifuges, at which it is up into the area of a centrally located above the centrifugal plate Sifter is directed, which lets the coarser parts fall back onto the centrifugal plate, and she follows that The aim is to achieve the highest possible intent for the fine material with simple means in continuous operation. Such mills have long been known in which the air stream swept through by the discharging air stream Chamber is arranged above the centrifugal plate and the coarse is then extracted from the Airflow falls to get back onto the spinner, but it has been shown to do so No fine sifting is achieved on its own, even if one instead of a single discharge chamber is used has arranged several merging into one another. Also that in another mill of this type you can do this over the centrifugal plate provided housing rounded concave and with a far inward against the Circumferential axis provided protruding inner edge, could not bring sufficient success.
Gemäß der Erfindung wird vielmehr der Sichter aus einer im oberen Teil des Gehäuses auf einer lotrechten Welle sitzenden, mit einem nach unten gerichteten konischen Rand versehenen, schnell umlaufenden Scheibe und einem mit Abstand darunter angeordneten zentralen, mit seiner Öffnung nach oben gerichteten Absaugrohr für das P^eine gebildet. Dadurch ergibt sich vor allem die Möglichkeit, den Schleuderteller und den Sichter in ihren Drehzahlen unabhängig voneinander zu halten, und da naturgemäß auch der Sog in dem Absaugrohr ganz frei von jenen beiden Drehzahlen und ihren Wirkungen bemessen werden kann, so ist eine weitestgehende Regelfähigkeit gewährleistet, die es erlaubt, alle Einflüsse je nach dem zu verarbeitenden Gut auf das gewünschte Ergebnis ganz fein einzustellen.According to the invention, the sifter is rather from one in the upper part of the housing to a vertical one Shaft seated, provided with a downwardly directed conical edge, rapidly rotating Disc and a spaced central one below, with its opening facing upwards Suction tube formed for the P ^ one. This results in the possibility of using the centrifugal plate and to keep the sifter's speeds independent of each other, and naturally also the Suction in the suction tube can be measured completely free of those two speeds and their effects can, the greatest possible degree of control is guaranteed, which allows all influences depending on the Fine-tune the goods to be processed to the desired result.
Die Zeichnung stellt schematisch ein Ausführungsbeispiel der Erfindung dar und zeigt eine Schleudermühle in senkrechtem Schnitt. In dem Gehäuse 1, in welches das Gut mittels der Zuleitung 2 eingeführt wird, läuft auf der in der Gehäusesohle gelagerten und in schnelle Drehung versetzten lotrechten Welle der Schleuder teller 3 um. Um dessen nach oben hin emporgebördelten Rand sind im Gehäuse 1 Rippen 4 an der Gehäusewand vorgesehen. Im oberen Teil des Gehäuses 1 ist in dessen Decke eine gleichfalls rasch Schleudermühle mit einem am GrundeThe drawing shows schematically an embodiment of the invention and shows a centrifugal mill in vertical section. In the housing 1, into which the goods are introduced by means of the supply line 2 runs on the vertical shaft, which is mounted in the housing base and rotated rapidly the spin plate 3 to. To its upwards Flanged up edge are provided in the housing 1 ribs 4 on the housing wall. In the upper part of the Housing 1 is in the ceiling of a likewise fast centrifugal mill with one at the bottom

Mit Abstand unter ihr ist ein ortsfestes Absaugerohr 8 angebracht, dessen Mündung nach oben gegen die Scheibe 7 gerichtet ist. Das vom Teller 3 über seinen Rand gegen die Gehäusewand geschleuderte und hierbei zerkleinerte Gut wird, von den Rippen 4 geleitet, nach oben hin von dem vom Teller 3 erzeugten und durch den Sog im Rohr 8 unterstützten Luftstrom emporgetragen in den Bereich der Scheibe 7. Grobe Teile fallen von ihr auf den Teller 3 zu erneuter Behandlung zurück, während Feines von dem Sog durch das Rohr 8 abgeleitet wird.circumferential, vertical shaft 5 is provided, which is provided with the downwardly directed, conical edge 6 Disk 7 carries. At a distance below her a stationary suction pipe 8 is attached, the mouth of which is directed upwards against the disc 7. That thrown from the plate 3 over its edge against the housing wall and comminuted material is guided by the ribs 4, upwards by that of the plate 3 The air flow generated and supported by the suction in the pipe 8 is carried up into the area of the disk 7. Coarse parts fall back from it on the plate 3 for further treatment, while fine parts from that Suction is diverted through the pipe 8.
