Description
Es ist bekannt, Holländer, die vorzugsweise als Wasch-, Misch- und BleichholländerIt is known to Dutch, preferably as washing, mixed and bleaching Dutch
... sowie zur Einmengung von Füllstoff dienen, mit einer oder mehreren Förderschnecken zu versehen, die den Zweck haben, den Umlauf der Stoffmasse im Holländer zu fördern. Man hat auch versucht, mit dieser Förderschnecke gleichzeitig das Zerhacken und Zerreißen größerer vorkommender Stücke von Papierstoff im Trog zu bewirken, indem man den Rand der Schnecke gezahnt hat. Doch hatte die beabsichtigte Wirkung, die nur zum Teil erzielt wurde, andererseits den Nachteil im Gefolge, daß die größeren Papierstoffstücke, anstatt zerkleinert zu werden, sich über den Schneckenkamm legten und den Durchgang versperrten, sowie den Umlauf der Stoffmassen im Holländer hemmten.... as well as for the incorporation of filler, with one or more screw conveyors provided, which have the purpose of promoting the circulation of the substance in the Dutch. Man also tried chopping and tearing at the same time with this screw conveyor to cause larger pieces of pulp occurring in the trough by having the edge of the auger serrated. But had the intended effect, which was only partially achieved, on the other hand the disadvantage in As a result, instead of being shredded, the larger pieces of stock spread over the Snail combs and blocked the passage, as well as the circulation of the masses of matter in the Hollander inhibited.
Die vorliegende Erfindung, die diese Übelstände beseitigt und es ermöglicht, ganze Bogen von Zellulose, Halbstoffen usw. zu verarbeiten, besteht darin, daß die Schnecke auf beiden Seiten mit einer Anzahl dachartig angeordneter Messer versehen ist, welche die Papierstoffstücke während des Umlaufs zerschneiden. The present invention, which eliminates these drawbacks and makes it possible, whole To process sheets of cellulose, pulp, etc., consists in opening the screw is provided on both sides with a number of knives arranged like a roof, which the Cut pieces of paper stock as it circulates.
In der Zeichnung ist die neue Schnecke in Fig. ι in Seitenansicht, und in Fig. 2 in Vorderansicht dargestellt.In the drawing, the new screw is in Fig. Ι in side view, and in Fig. 2 in front view shown.
Nach der Erfindung . sind auf beiden Seitenflächen der Schnecke α eine Anzahl Messer b dachartig angeordnet,-, die vermöge ihrer Schneiden die Stoffmassen beim Vorwärtstreiben zerschneiden.According to the invention. a number of knives b are arranged like a roof on both side surfaces of the worm α , - which, by virtue of their cutting edges, cut the masses of material when propelled forward.
