Description

Saugwalze für Papiermaschinen Bei-der Herstellung von Zellstoffwatte und Papier, ist eine ausreichende Entwässerung Grundbedingung.Suction roll for paper machines During the production of cellulose wadding and paper, adequate drainage is a basic requirement.

Es sind verschiedene Systeme von Saugwalzen und Saugkästen bekannt, die jedoch teils unvollkommen, teils außerardentlich teuer sind, während die Saugwalze nach der Erfindung einfach und billig in der Ausfühlung und in der Saugwirkung den bekannten Einrichtungen ebenbürtig ist.Various systems of suction rolls and suction boxes are known, which are partly imperfect, partly extremely expensive, while the suction roll according to the invention simple and cheap to the touch and in the suction is on a par with known institutions.

Die Saugwalze nach der Erfindung besteht aus einem Walwx&ern, an dessen Umfang biegsame, federnde Lamellen o. dgl. angeardnet sind. Die Lamellen bestehen vorzugsweise aus Gummi oder aus einem anderen geeigneten Stoff, der sich beim Anlegen an das Sieb krümmt und beim Abflauen wieder streckt. Die zwischen je zwei Lamellen befindlichen Zellen oder Luftkammein sind durch feststehende Stirnwände gegen Lufteintritt von der Seite her gesichert. Die Saugwirkung kommt dadurch zustand--, daß der Inhalt der Luftkammern sich infolge des Streckens der Lamellen beim Ablauf vom Sieb vergrdßert, so daß eine Luftverdünnung entsteht. Durch Regeluni der Umfangsgeschwindigkeit der Walze- läßt sich jeder gewünschte Grad der Entwässerung erreichen.The suction roll according to the invention consists of a Walwx & ern, on the circumference of which flexible, resilient lamellae or the like are attached. The lamellas are preferably made of rubber or some other suitable material which bends when it is placed against the screen and stretches again when it slackens. The cells or Luftkammein located between each two slats are secured by fixed end walls against entry of air from the side. The suction effect comes about - that the content of the air chambers increases as a result of the stretching of the lamellae as they run off the sieve , so that a dilution of the air occurs. Any desired degree of drainage can be achieved by regulating the circumferential speed of the roller.

Da sich durch das unmittelbare, Anschlagen der Lamellen an das Sieb, Schwierigkeiten hinsichtlich der Geräusche, Abnutzung undWasserableitung ergeben können, ist die Saugwalze zweckmäßig in ein-er Wanne gelagert, die der Funn der Walze angepaßt sein kann, wadurch auch noch die Saugwirkung erhöht wird. Außerdem ka:mi die Wanne mit einer gelrochten Platte aus Blech, Ha-rtguinmi c,.dgl. abgedeckt sein, die unmittelbar unter dem umlaufenden Sieb anliegt und so das Anschlagen an das Sieb selbst ohne Verniinderung der Saugwirkung vermeidet.Since the immediate impact of the lamellae on the sieve, Difficulties arise in terms of noise, wear and water drainage can, the suction roll is expediently stored in a tub, which the funn of Roller can be adapted, which also increases the suction effect. aside from that ka: mi the tub with a perforated sheet metal plate, Ha-rtguinmi c, .dgl. covered be, which rests directly under the rotating sieve and so the impact on avoids the sieve itself without reducing the suction.

In der Zeichnung ist die Erfindung schaubildlich dargestellt.The invention is shown diagrammatically in the drawing.

Der Walzenkerni mit den 1.amellen2 ist in einer Wanne3 gelagext, die mit den nicht dargestellten Stimwänden und einem gelochten Deckel 4 aus Blech, Hartgummi o-. dgl. ein geschlossemes Gehäuse bildet. Die abgesaugte Flüssigkeit wird durch den Stutzen g abgeleitet.The roller core with the 1.amellen2 is gelagext in a tub3, which with the end walls (not shown) and a perforated cover 4 made of sheet metal, hard rubber o-. Like. Forms a closed housing. The liquid sucked off is drained off through the nozzle g .
