Patentirt im Deutschen Reiche vom 6. August 1896 ab.Patented in the German Empire on August 6, 1896.
Um eine völlig spelzenfreie Kochung von Cellulose zu ermöglichen, ist es vorfheilhaft, die von der Hackmaschine kommenden vorsortirten Holzhackspähne recht gleichmäfsig zu! zerkleinern.In order to enable cellulose to be cooked without any hulls, it is beneficial to the pre-sorted wood chips coming from the chopping machine are quite even to! crush.
JDiese Zerkleinerung kann ohne wesentlichen Zeitverlust und ohne besonderen Kraftaufwand unmittelbar mit der Beförderung der aus der Hackmaschine kommenden Spähne zur Cyclone über den Kocherboden verbunden werden, wenn zur Beförderung der Spähne ein Exhaustor benutzt wird, der gleichzeitig als Raspelmaschine ausgebildet ist. Das Raspeln der Holzspähne erfolgt hierbei durch Arbeiten von sich drehenden Messern über auf einem Grundwerk befestigten, sägezahnartig wirkenden Stahlmessern. JThis comminution can be carried out without any significant loss of time and without any special effort immediately with the transport of the chips coming from the chopping machine to the Cyclone can be connected via the bottom of the digester if an exhaustor is used to transport the chips is used, which is also designed as a rasping machine. The rasping of the Wood chips are made here by working rotating knives over on a base attached, sawtooth-like steel knives.
Auf beiliegenden Zeichnungen ist die Vorrichtung durch Fig. 1 und 2 im Querschnitt dargestellt.On the accompanying drawings, the device is shown in cross-section through Figs shown.
Es ist A das Eingangsrohr, JB das Ausgangsrohr für die während des Durchganges fein zu mahlenden Spähne. Die Exhaustorflügel sitzen auf einer Welle mit Antriebscheibe C und laufen zwischen dem raspelartig ausgebildeten Grundwerke D, das in Gestalt zweier gegenüberliegender, mit den Messern sich zugeneigter Platten im Gehäuse festgelegt ist. Die Ausführung der Grundplatten kann dabei beliebig 'sein.It is A, the input pipe, JB the initial pipe for during the passage finely milled shavings. The Exhaustorflügel sit on a shaft with drive disk C and run between the rasp-like designed base D, which is fixed in the form of two opposing plates inclined with the knives in the housing. The design of the base plates can be arbitrary.
Fig. 3 und 4 geben Draufsicht und Schnitt durch eine Ausführungsform dieser Grundplatten. Jede der beiden Platten ist am besten mit eingegossenen Messern versehen. Man könnte die Grundplatten auch glatt fertigen, mit gehobelten Arbeitsleisten versehen und auswechselbare Messer bezw. Messerringe darauf befestigen. Jedoch wird die Anfertigung aus einem Stück vorzuziehen sein.3 and 4 give a plan view and section through an embodiment of these base plates. Each of the two plates is best provided with embedded knives. Man The base plates could also be made smooth, provided with planed work strips and interchangeable Knife or Attach knife rings to it. However, it will be preferable to make it in one piece.
Die Messer können radial zum Plattenmittelpunkt gerichtet sein, sind aber vortheilhafter schneckenförmig, wie gezeichnet, und dann mit den inneren Enden nicht auf, sondern excentrisch gegen den Mittelpunkt gerichtet, so dafs die Grundwerkmesser zu den darüber laufenden Flügelradmessern stets divergiren, also scheerenschnittartig wirken (Fig. 7 schematisch angedeutet). The knives can be directed radially towards the center of the plate, but are more advantageous helical, as shown, and then with the inner ends not on, but eccentric directed towards the center, so that the basic work knives to those running above it Impeller blades always diverge, that is, act like a scissor cut (Fig. 7 indicated schematically).
Zwischen den Messern des Grundwerkes laufen nun nach vorliegender Ausführungsform sechs Flügel E. Es kann auch deren eine gröfsere oder kleinere Anzahl angeordnet sein. According to the present embodiment, six blades E now run between the blades of the base. A larger or smaller number of these can also be arranged.
Fig. 5 und 6 zeigen Ansicht und Schnitt durch diese trapezförmigen Flügel, die je zwei scharfe Messerkanten besitzen. Die letzteren, auf den Grundwerksplatten arbeitend, bewirken eine ganz gleichmäfsige Zerkleinerung der durch den Exhaustor geschickten Spähne.Fig. 5 and 6 show a view and section through this trapezoidal wing, each two sharp Own knife edges. The latter, working on the base plates, cause one very even size reduction of the chips sent through the exhaustor.
Die Ein- und Abführung des Mahlgutes und der Luft geschieht in der Weise, dafs die Luft zugleich von der Messerscheibe mit dem Mahlgut eingeführt wird. Die Wirkung der Raspelmaschine ist eine so sichere, dafs es nicht mehrmaligen Durchführens des Mahlgutes durch den Schneideapparat bedarf.The introduction and removal of the ground material and the air takes place in such a way that the air is introduced at the same time from the knife disc with the grist. The effect of the rasp machine is so safe that it is not necessary to pass the ground material through the cutting device several times.
Die beschriebene Vorrichtung kann auch für die Zerkleinerung anderer geeigneter Stoffe als nur der Hackspähne benutzt werden.The device described can also be used for the comminution of other suitable substances than only the wood chips can be used.
