  Vorrichtung zur Reinigung des   Filzes von Pappen-und Papiermaschinen   während des Betriebes. 
 EMI1.1 
 Vorrichtungen dieser Art liegen die   Schaufelräder stets auf   der   Arbeitsseite   des Filzes und bewirken infolgedessen, dass zwar ein Teil der   Stoff-oder Schlammteilchen fortgespült,   ein anderer Teil aber tiefer in den Filz hineingedrückt wird. Dieser Mangel wird gemäss vorliegender Erfindung dadurch beseitigt, dass der Filz in der Flüssigkeit unter das Schaufelrad derart herumgeführt wird, dass letzteres auf der der   Arbeitsfläche   des Filzes entgegengesetzten Seite liegt. 



   Dadurch erzielt man. wie   Ver ; ; uche   ergeben haben. eine besonders wirksame und vorteilhafte Reinigung des Filzes, was wahrscheinlich darauf   zurückzuführen   ist. dass die Flüssigkeit mittels des Schaufelrades von der Rückseite des Filzes her durch diesen hindurchgedrückt wird und dabei alle Schmutzteilchen   heraustreibt.   



   Zwar ist bereits es bekannt, den Filz von der   Rückseite   her mit   Wasehflüssigkeit   zu behandeln. 



  Hierbei wird die   Flüssigkeit durch Spritzrohre, welche   oberhalb des die   Schaufelräder   enthaltenden Troges auf der Eintritt-seite angeordnet sind, in   kräftigen   Strahlen gegen die Rückseite des Filzes gespritzt. 



  Dies bedingt jedoch einen hohen Wasserverbrauch, auch könnte der Nachteil eintreten, dass das auf der Arbeitsseite des Filzes vorgesehene Schaufelrad die Wirkung des auf der Rückseite des Filzes angeordneten Spritzrohres zum Teil oder ganz aufhebt.

   PATENT-ANSPRÜCHE :
1. Vorrichtung zur Reinigung des Filzes von Pappen-und Papiermaschinen während des Betriebes mittels eines in der   Waschflüssigkeit   umlaufenden Schaufelrades, dadurch   gekennzeichnet,   dass der Filz in der Flüssigkeit unter das Schaufelrad derart herumgeführt wird, dass letzteres auf der der Arbeits-   fläche   des Filzes abgewandten Seite liegt.

  Device for cleaning the felt of cardboard and paper machines during operation.
 EMI1.1
 In devices of this type, the paddle wheels are always on the working side of the felt and consequently have the effect that, although some of the fabric or sludge particles are washed away, another part is pushed deeper into the felt. According to the present invention, this deficiency is eliminated by guiding the felt in the liquid under the paddle wheel in such a way that the latter lies on the side opposite the working surface of the felt.



   This achieves. like Ver; ; uche have revealed. a particularly effective and beneficial cleaning of the felt, which is probably due to it. that the liquid is pressed through the back of the felt by means of the paddle wheel and thereby drives out all dirt particles.



   It is already known to treat the felt from the back with washing liquid.



  Here, the liquid is sprayed in powerful jets against the back of the felt through spray pipes which are arranged above the trough containing the paddle wheels on the inlet side.



  However, this requires a high level of water consumption, and the disadvantage could also arise that the paddle wheel provided on the working side of the felt partially or completely neutralizes the effect of the spray tube arranged on the back of the felt.

   The trough half and, if necessary, a drain cock o also provided on the right trough half, which can also be more or less influenced during operation in order to prevent the dirt from collecting on the container bottom.



   PATENT CLAIMS:
1. Device for cleaning the felt of cardboard and paper machines during operation by means of a paddle wheel rotating in the washing liquid, characterized in that the felt in the liquid is guided around under the paddle wheel in such a way that the latter is facing away from the work surface of the felt Side lies.
