Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf einen Knotenfang mit schrägstehenden Siebplatten in ebensolchen Schlagflügeln, bei welchem der Stoff von oben zwischen Siebplatten und Schlagflügeln eintritt. Die Erfindung besteht darin, daß die Schlagflügel im untersten Teile des Troges gelagert sind, wodurch das Absetzen der nicht durch die Siebplatten gegangenen. Verunreinigungen infolge der beim Drehpunkte der Schlagflügel vorhandenen geringeren Bewegung erleichtert werden soll. Außerdem ist die ganze Anordnung so getroffen, daß auch während des Betriebes die sich im Raum b absetzenden Stoffteilchen entfernt werden können.The invention relates to a knot catcher with inclined sieve plates in such flapping wings, in which the substance enters from above between sieve plates and flapping wings. The invention consists in that the flapping wings are stored in the lowermost part of the trough, whereby the settling of those that have not passed through the sieve plates. Impurities as a result of the lesser movement present at the pivot points of the flapping wing is intended to be relieved. In addition, the whole arrangement is made so that the particles of material settling in space b can also be removed during operation.

Ein solcher Knotenfänger ist in der Zeichnung im Schnitt dargestellt.Such a knot catcher is shown in section in the drawing.

Derselbe arbeitet in folgender Weise: Der aus dem Sandfang kommende Papierstoff gelangt durch die Rinne f zwischen die schrägliegenden, schwingenden Flügel g und die Siebplatten α und wird durch die Schwingung der Flügel g durch die Schlitze c gedrückt. The same works in the following way: The paper stock coming from the sand trap passes through the channel f between the inclined, oscillating wings g and the sieve plates α and is pressed through the slots c by the oscillation of the wings g.

Die zurückgehaltenen gröberen Stoffteile und Verunreinigungen werden teils durch den von oben eintretenden frischen Stoff, teils durch ihre eigene Schwere, teils dadurch, daß die schwingende Bewegung des Flügels am " freien Ende eine heftigere ist als in der Nähe des Drehpunktes und ferner dadurch, daß die Flügel g nicht horizontal, sondern schräg liegen, nach unten in den Raum b befördert, wo sie sich infolge der Form desselben und der herrschenden Ruhe in der Nähe des Stutzens d absetzen und abgelassen werden können.The coarser pieces of material and impurities that are retained are partly due to the fresh material entering from above, partly due to their own gravity, partly due to the fact that the swinging movement of the wing at the "free end" is more violent than in the vicinity of the pivot point and also due to the fact that the Wings g do not lie horizontally, but inclined, transported downwards into space b , where they can settle and be drained off due to the shape of the same and the prevailing calm in the vicinity of the nozzle d.
