Description

Die Erfindung betrifft eine Pressenpartie einer Maschine zur Herstellung einer Faserstoffbahn, insbesondere einer Papier- und/oder Kartonbahn mit wenigstens zwei aufeinander folgenden, doppelt befilzten Pressen.The invention relates to a press section of a machine for producing a Fibrous web, in particular a paper and / or cardboard web with at least two successive, double felted presses.

Derartige Presenpartien sind bekannt und dienen zur Entwässerung der Faserstoffbahnen. Die Schuhpressen bilden dabei eine konkave Anpreßfläche, die es erlaubt, mit einer zylindrischen Gegenwalze einen verlängerten Preßspalt zu bilden. Derartige Preßspalte können die Entwässerungsleistung erheblich verbessern.Such press sections are known and are used for dewatering the fibrous webs. The shoe presses form a concave contact surface that it allows an extended press nip with a cylindrical counter roll form. Such press nips can significantly improve drainage performance.

Probleme ergeben sich jedoch wegen des hohen Wassergehaltes der Faserstoffbahn bei der Abführung des ausgepreßten Wassers im ersten bzw. vorgelagerten Preßspalt.However, problems arise due to the high water content of the fibrous web in the discharge of the squeezed water in the first or upstream Press nip.

Die Aufgabe der Erfindung ist es daher, eine einfach aufgebaute Pressenpartie mit verbesserter Entwässerung im ersten bzw. vorgelagerten Preßspalt zu schaffen.The object of the invention is therefore a simply constructed press section with improved drainage in the first or upstream press nip create.

Erfindungsgemäß wurde die Aufgabe dadurch gelöst, daß der Preßspalt der in Bahnlaufrichtung vorgelagerten Presse von einer durchbiegungsgesteuerten Schuhwalze und einer besaugten Walze gebildet wird.According to the invention the object was achieved in that the press nip in Upstream press direction from a deflection-controlled Shoe roller and an aspirated roller is formed.

Die Schuhpreßwalzen werden dabei im allgemeinen von einem flexiblen Preßmantel gebildet, der über ein Preßelement mit konkaver Anpreßfläche läuft. Dies erlaubt die Bildung eines verlängerten Preßspaltes mit einer zylindrischen Gegenwalze, so daß die Faserstoffbahn im Preßspalt über eine längere Strecke dem Preßdruck ausgesetzt und damit internsiver entwässert wird. Zudem setzt der Druck im Preßspalt nicht mehr schlagartig ein, dieser kann vielmehr von einem niedrigen Wert beispielsweise kontinuierlich auf einen höheren Wert gebracht werden.The shoe press rolls are generally made of a flexible press jacket formed, which runs over a pressing element with a concave contact surface. This allows the formation of an extended press nip with a cylindrical Counter roll, so that the fibrous web in the press nip over a longer distance exposed to the pressure and thus more internally drained. In addition, sets the pressure in the press nip no longer suddenly, this can be from one low value, for example, continuously brought to a higher value become.

Die beidseitig der Faserstoffbahn angeordneten Entwässerungsfilze sorgen dabei nicht nur für eine ausreichende Kapazität zur Aufnahme des ausgepreßten Wassers sondern auch für die Gleichseitigkeit der Faserstoffbahn. Außerdem wird durch die Verwendung einer besaugten Walze beim vorgelagerten bzw. ersten Preßspalt die Aufnahmefähigkeit für das ausgepreßte Wasser wesentlich gesteigert.The drainage felts arranged on both sides of the fibrous web ensure this not only for sufficient capacity to take the squeezed out Water but also for the equilibrium of the fibrous web. Furthermore is achieved by using a vacuumed roller in the upstream or first press nip the capacity for the squeezed water essential increased.

Insbesondere bei hohen Geschwindigkeiten ist es von Vorteil, wenn die Faserstoffbahn ausgehend von der Übernahme von einer vorgelagerten bis zur Übergabe an eine folgende Einheit zumindest von einem Band, Sieb, Filz o. ä. gestützt ist. Dies führt zu einer sicheren Bahnführung und vermindert dadurch die Häufigkeit von Bahnabrissen.Especially at high speeds, it is advantageous if the fibrous web starting from the takeover of an upstream to the Transfer to a subsequent unit at least from a belt, sieve, felt or similar is supported. This leads to a safe web guidance and thereby reduces the frequency of web breaks.

Die Entwässerungsleistung der Pressenpartie kann außerdem noch wesentlich verbessert werden, wenn der in Bahnlaufrichtung folgende, doppelt befilzte Preßspalt zumindest von einer durchbiegungsgesteuerten Walze vorzugsweise in Form einer Schuhwalze gebildet wird. Dies ermöglicht es, die Pressenpartie auf zwei Preßspalte zu begrenzen, was den Aufwand erheblich reduziert.The dewatering performance of the press section can also be significant can be improved if the following, double felted in the direction of web travel Press nip preferably from at least one deflection-controlled roller is formed in the form of a shoe roller. This enables the press section limited to two press nips, which significantly reduces the effort.

Die Führung der Faserstoffbahn kann dabei von jeweils einem Entwässerungsfilz der Preßspalte übernommen werden. Besonders vorteilhaft ist es in diesem Fall, wenn ein Entwässerungsfilz der ersten Presse die Faserstoffbahn von der vorgelagerten Siebpartie übernimmt und der auf der anderen Seite der Faserstoffbahn angeordnete Entwässerungsfilz der folgenden Presse die Faserstoffbahn von dem Entwässerungsfilz der ersten Presse übernimmt und an die folgende Trockenpartie übergibt.The fiber web can be guided by a drainage felt the press nip are taken over. It is particularly advantageous in this Case when a first press dewatering the fibrous web from the upstream screen section and on the other side of the fibrous web arranged dewatering felt of the following press the fibrous web from the drainage felt of the first press and to the next one Dryer section passes.

Zur Gewährleistung einer sicheren Bahnführung sowie einer Verringerung der Rückbefeuchtung des Preßspaltes ist es des weiteren von Vorteil, wenn der die Faserstoffbahn führende Entwässerungsfilz der ersten Presse um die besaugte Walze läuft.To ensure safe web guidance and a reduction in Remoistening of the press nip, it is also advantageous if the Dewatering felt leading the fibrous web of the first press around the vacuumed Roller is running.

Nachfolgend soll die Erfindung an einem Ausführungsbeispiel näher erläutert werden. In der beigefügten Zeichnung zeigt die Figur eine schematische Darstellung der Pressenpartie mit zwei Preßspalten 5 und 9. Dabei ist um die Walzen jedes Preßspaltes 5 und 9 je ein endloser Enfwässerungsfilz 11, 12 geführt, der zur Aufnahme des ausgepreßten Wassers dient. Außerdem besitzen beide Pressen 2 und 3 je eine durchbiegungsgesteuerte Schuhwalze 6 und 10. Während der Preßspalt 5 der in Bahnlaufrichtung 4 vorgelagerten Presse 2 mit einer zylindrischen besaugten Walze 15 gebildet wird, erfolgt dies in der folgenden Presse 3 mit einer zylindrischen glatten Walze 16.The invention will be explained in more detail below using an exemplary embodiment become. In the accompanying drawing, the figure shows a schematic representation the press section with two press nips 5 and 9. This is around the rollers each press nip 5 and 9 each have an endless dewatering felt 11, 12, which serves to absorb the squeezed water. They also own Presses 2 and 3 each have a deflection-controlled shoe roller 6 and 10. During the press nip 5 of the upstream press 2 in the web running direction 4 with a cylindrical suction roll 15 is formed, this is done in the following Press 3 with a cylindrical smooth roller 16.

Die durchbiegungsgesteuerten Schuhwalzen 6 und 10 sorgen dabei für ein einstellbares, vorzugsweise gleichmäßiges Entwässerungsprofil axial entlang jedes Preßspaltes 5 und 9. Durch die Verwendung von jeweils zwei Entwässerungsfilzen 11, 12 in jedem Preßspalt 5 und 9 ist eine ausreichend große Kapazität zur Aufnahme des ausgepreßten Wassers gegeben. Außerdem kann die Faserstoffbahn 1 von jeweils einem Entwässerungsfilz 11, 12 gestützt durch die Pressenpartie geführt werden. The deflection-controlled shoe rollers 6 and 10 ensure that adjustable, preferably uniform drainage profile axially along each press nip 5 and 9. By using two drainage felts each 11, 12 in each press nip 5 and 9 is a sufficiently large capacity given to absorb the squeezed water. In addition, the Fiber web 1 each of a drainage felt 11, 12 supported by the Press section are performed.

Die besaugte Walze 15 besitzt einen perforierten Walzenmantel, dessen Innenraum mit einer Vakuumquelle verbunden ist. Der Unterdruck sorgt nicht nur für eine sichere Führung der Faserstoffbahn 1 nach dem Verlassen des ersten Preßspaltes 5 am Entwässerungsfilz 11 sondern auch für eine verringerte Rückbefeuchtung der Faserstoffbahn 1 durch den Entwässerungsfilz 11.The vacuumed roller 15 has a perforated roller shell, the interior is connected to a vacuum source. The vacuum not only ensures secure guidance of the fibrous web 1 after leaving the first Press nip 5 on the drainage felt 11 but also for a reduced Remoistening of the fibrous web 1 through the dewatering felt 11.

Um eine sichere Führung der Faserstoffbahn 1 zu gewährleisten, wird die Faserstoffbahn 1 vom Sieb 13 einer vorgelagerten Einheit 7 direkt abgenommen. Dies erfolgt mit Hilfe einer besaugten Leitwalze, die vom Entwässerungsfilz 11 der besaugten Walze 15 der ersten Presse 2 umschlungen ist. Nach dem ersten Preßspalt 9 wird wiederum von einer besaugten Leitwalze unterstützt die Faserstoffbahn 1 an den auf der anderen Seite der Faserstoffbahn 1 angeordneten Entwässetungsfilz 12 übergeben. Dieser die glatte Walze 16 umlaufende Entwässerungsfilz 12 übergibt die Faserstoffbahn 1 wiederum von einer besaugten Leitwalze unterstützt an ein Trockensieb 14 der folgenden Einheit 8. Diese Einheit 8 ist hier als Trockenpartie ausgeführt, in der die Faserstoffbahn 1 gemeinsam mit dem Trockensieb 14 abwechselnd über Trockenzylinder und Leitwalzen geführt wird.In order to ensure secure guidance of the fibrous web 1, the fibrous web is 1 directly removed from the screen 13 of an upstream unit 7. This is done with the aid of a suction guide roller, which is removed from the drainage felt 11 the sucked roller 15 of the first press 2 is wrapped. After the first Press nip 9 is in turn supported by a suction guide roller Fibrous web 1 arranged on the other side of the fibrous web 1 Hand over drainage felt 12. This the smooth roller 16 rotating Drainage felt 12 in turn transfers the fibrous web 1 from one evacuated guide roller supports on a dryer fabric 14 of the following unit 8. This unit 8 is designed here as a dryer section in which the fibrous web 1 together with the dryer 14 alternately via drying cylinders and Guide rollers is guided.
