Bei den zur Sortirung des Holzfaserstoffes verwendeten Cellulosereinigern und bei anderen Äbscheidungsapparaten, welche in Flüssigkeiten rotiren, müssen die Stopfbüchsen gegen das Eindringen von Unreinigkeiten (Holzfaser) aus der Flüssigkeit geschützt werden. Dies ist bis jetzt nicht im vollkommenen Mafs erreicht worden, da der Flüssigkeitsdruck aufserhalb des sich drehenden Cylinders das Eindringen dieser für die Slopfbüchsendichtung schädlichen Theile unvermeidlich macht.With the cellulose cleaners used to sort the wood pulp and with others Separation apparatus, which rotate in liquids, must hold the stuffing boxes against the Penetration of impurities (wood fiber) from the liquid are protected. This is up has not now been reached in perfect measure, since the fluid pressure is outside the The rotating cylinder prevents the penetration of these parts which are harmful to the sloping sleeve seal makes inevitable.
Bei der vorliegenden Anordnung ist dieser Uebelstand dadurch ganz vermieden, dafs in der Stopfbüchse des Cylinderhalses selbst ein Ueberdruck hergestellt wird, welcher das Eindringen von Theilen aus der zu reinigenden Flüssigkeit ganz unmöglich macht. Dieser Ueberdruck wird dadurch hergestellt, dafs zur Stopfbüchse Wasser oder andere Flüssigkeit unter einem Druck zugeführt ist, der gröfser ist als der von der Sortirungsflüssigkeit ausgeübte Druck, und dafs diese Flüssigkeit bezw. Wasser zwischen Stopfbüchse und Cylinderhals hindurch nach dem Sortirbottich sich bewegt und nach dort abfliefstIn the present arrangement this disadvantage is completely avoided by the fact that in the stuffing box of the cylinder neck itself an overpressure is produced, which prevents the penetration of parts of the liquid to be purified makes it quite impossible. This Overpressure is created by bringing water or other liquid to the stuffing box is supplied under a pressure which is greater than that exerted by the sorting liquid Pressure, and that this liquid resp. Water between the stuffing box and the cylinder neck moves through to the sorting tub and flows off there
Die Anordnung ist in Fig. 1 und 2 der Zeichnung dargestellt.The arrangement is shown in Figs. 1 and 2 of the drawing.
A ist der Cylinder des Cellulosereinigers, B der Trog, in welchem derselbe gelagert ist. , Ueber den Hals des Cylinders ist ein Abdichtungsring α von einem in der Zeichnung ersichtlichen muschelförmigen Querschnitt gelegt , in dessen inneren, dem Cylinderhals zugekehrten Hohlraum durch eine Röhre b beständig Wasser unter , einem Druck zugeführt wird, der gröfser ist als der Druck der aufserhalb des Cylinders im Trog B befindlichen Stoffflüssigkeit. . A is the cylinder of the cellulose cleaner, B the trough in which it is stored. Over the neck of the cylinder is placed a sealing ring α of a shell-shaped cross-section shown in the drawing, in the inner cavity of which, facing the cylinder neck, water is constantly fed through a tube b at a pressure that is greater than the pressure outside the Cylinders in trough B located substance liquid. .
Dieser Abdichtungsring ist mittelst einer Gummi- oder Filzplatte C mit der Trogwand verbunden und wird aufserdem durch Stellschrauben S und den Gummibuffer d leicht an die Stirnseite des Cylinderhalses angedrückt.This sealing ring is connected to the trough wall by means of a rubber or felt plate C and is also pressed lightly against the face of the cylinder neck by adjusting screws S and the rubber buffer d.
Wenn der Apparat in Thätigkeit ist, so findet zwischen dem Abdichtungsring α und dem Cylinderhals, so weit es der geringe Spielraum zwischen beiden gestattet, beständig ein leichtes Durchfliefsen von Wasser unter einem Druck statt, welcher ein Eindringen von Stofffasern in die Abdichtung unmöglich macht. Diese neue- Abdichtung wirkt dadurch sicher und zuverlässig, während gleichzeitig der zuvor so bedeutende Kraftverlust und die Abnutzung des Apparates auf ein Minimum beschränkt sind.When the apparatus is in operation, there is a constant flow of water between the sealing ring α and the cylinder neck, as far as the small clearance between the two permits, under a pressure which makes it impossible for fabric fibers to penetrate the seal. This new seal is therefore safe and reliable, while at the same time the previously so significant loss of force and wear and tear on the apparatus are reduced to a minimum.
Die Verpackung dieser Stopfbüchsen wurde nämlich bis jetzt mittelst Hanfes, Asbestes, Specksteinschnüre u. dergl. bewerkstelligt. Um vollständig dicht zu sein, mufsten die Stopfbüchsen stets gut angezogen werden, wodurch dieselben aber der raschen Cylinderdrehung einen grofsen Widerstand entgegensetzten, der noch erheblich vermehrt wurde, wenn Stoff in die Stoff büchsen gelangte, dessen Fasern sich allmälich immer fester einklemmten. Der zum Betrieb des Apparates erforderliche Kraftaufwand wurde dadurch ganz unverhältnifsmä'fsig gesteigert und damit zugleich die Ab-The packing of these stuffing boxes has until now been made with hemp, asbestos, Soapstone cords and the like. In order to be completely tight, the stuffing boxes must must always be well tightened, which, however, results in the rapid rotation of the cylinder opposed a great resistance, which was increased considerably when matter was in the cans of fabric, the fibers of which gradually became wedged more and more tightly. The for The effort required to operate the apparatus was thereby quite disproportionate increased and at the same time the decrease
nutzung der Stopfbuchsen selbst, der Cylinderhälse, der Lager, kurz des ganzen Apparates.Use of the stuffing boxes themselves, the cylinder necks, the bearings, in short the whole apparatus.
Aufser bei den Cellulosereinigern läfst sich diese Abdichtung auch verwenden bei Pappenmaschinencylindern, Entwässerungscylindern für Holzstoff u. s. w., Zeugfängern, Knotenfängern, kurz allen Apparaten, bei welchen die Hälse eines im Wasser liegenden Siebcylinders gegen die Trogwand abgedichtet werden sollen.Except for the cellulose cleaners, this seal can also be used for cardboard machine cylinders, Drainage cylinders for wood pulp and so on, stuff catchers, knot catchers, in short all devices with which the necks a sieve cylinder lying in the water should be sealed against the trough wall.
