Abstract
Description
Die Erfindung betrifft eine Anordnung an Papiermaschinen zur Einstellung eines Flächengewichts-Querprofils mit Verdünnungswasser an hydraulischen Stoffaufläufen zur Herstellung von Papier oder Karton nach dem Oberbegriff des Anspruchs 1.The The invention relates to an arrangement of paper machines for adjustment a basis weight cross profile with dilution water on hydraulic headboxes for the production of paper or cardboard according to the preamble of Claim 1.
Die Einstellung des Flächengewichts-Querprofils mit Verdünnungswasser folgt aus der Zunahme der Anforderungen an die Qualität der Bahn, wofür die Gleichmäßigkeit der Faserorientierung über die Breite der Papier- oder Kartonbahn eine stets größere Rolle spielt. Durch die Zumischung von zusätzlichem Verdünnungswasser im Rohrverteiler wird die Stoffmenge feinfühlig über die Breite geregelt. Dies gilt insbesondere bei der Herstellung von Spezialpapieren.The Setting the basis weight cross profile with dilution water follows from the increase in train quality requirements, for what uniformity the fiber orientation over the Width of the paper or board web plays an increasingly important role. By the Addition of additional dilution water In the manifold, the amount of material is sensitively controlled across the width. this applies especially in the production of specialty papers.
Zu den Spezialpapieren gehören insbesondere Filterpapiere, Vliese und Dekor papiere. Die Filterpapiere und Vliese haben einen hohen Anteil an Zellstoff- und Kunststofffasern. Die Zellstoff- und Kunststofffasern neigen zur Bildung von Verspinnungen in der strömenden Faserstoffsuspension, d. h. dem Stoffstrom. Der Stoffauflauf muss deshalb so konzipiert werden, dass die Verspinnungen vermieden werden. Die Dekorpapiere haben dagegen einen hohen Anteil an Füllstoffen und Farbpartikeln, die in der strömenden Faserstoffsuspension dazu neigen, Ablagerungen an den Wänden der Strömungskanäle zu bilden. Das erhöht den Reinigungsaufwand des Stoffauflaufs beim Sortenwechsel. Der Stoffauflauf ist deshalb so zu gestalten, dass Ablagerungen an den Wänden der Strömungskanäle minimal gehalten oder vermieden werden.To belong to the special papers in particular filter papers, nonwovens and decorative papers. The filter papers and nonwovens have a high content of pulp and plastic fibers. The pulp and plastic fibers tend to form spun yarns in the pouring Pulp suspension, d. H. the material flow. The headbox must Therefore, be designed so that the spinning can be avoided. The decorative papers, however, have a high content of fillers and color particles in the flowing pulp suspension tend to form deposits on the walls of the flow channels. That increases the cleaning effort of the headbox during grade change. Of the Headbox is therefore designed so that deposits on the walls of the Flow channels minimal be kept or avoided.
Um diesen Anforderungen zu genügen, sind die hydraulischen Stoffaufläufe für Spezialpapiere mit Modulen ausgestattet, die die Wasserzumischung zur Einstellung des Flächengewichts-Querprofils erlauben. In den Modulen für die Wasserzumischung werden zwei Teilströme des Stoffstroms mit einem Verdünnungswasserstrom zusammengemischt. Der Gemischvolumenstrom muss dabei unabhängig von der Größe des Verdünnungswasser-Volumenstroms konstant bleiben.Around to meet these requirements, are the hydraulic headboxes for special papers equipped with modules that adjust the water for adjustment of the basis weight cross profile allow. In the modules for the Wasserzumischung be two part streams of the material stream with a dilution water stream mixed together. The mixture volume flow must be independent of the Size of the dilution water volume flow constant stay.

Aufgabe der Erfindung ist es daher, eine Anordnung an Papiermaschinen zur Einstellung des Flächengewichts-Querprofils mit Verdünnungswasser an hydraulischen Stoffaufläufen zur Herstellung von Papier oder Karton zu schaffen, die in kompakter Bauweise aufgebaut ist und dabei die Gefahr von Verspinnungen und Ablagerungen gering ist.task The invention is therefore an arrangement on paper machines for Setting the basis weight cross profile with dilution water on hydraulic headboxes to create paper or cardboard in a compact design is constructed while keeping the risk of spinning and deposits is low.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.These The object is solved by the features of claim 1.
Hierdurch wird eine Anordnung an Papiermaschinen geschaffen, die durch die Verwendung von Querstromverteilern für den Stoffstrom und das Verdünnungswasser eine konstante Einstellung des Geschwindigkeits- und Druckverlaufsprofils in der Suspension in einfacher Weise erlaubt. Die räumliche Anordnung der Volumenströme an Stoffstrom und Verdünnungswasser erfolgt in Verbindung mit Armaturen in Form von Ventilen für die Verdünnungswasserströme, die jeweils an einer Zentralbohrung der Mischeinrichtung angeordnet sind, so dass der Querstrom verteiler für das Verdünnungswasser benachbart zu den Mischeinrichtungen angeordnet werden kann. Lange Anschlussleitungen als auch Leitungsübergänge werden vermieden, wodurch Ablagerungen und Verspinnungen ebenfalls vermieden werden als auch schnelle Sortenwechsel möglich sind. Durch die Position der Armatur ist die Regelung zudem direkter.hereby an arrangement of paper machines is provided by the Use of cross-flow distributors for the flow and the dilution water a constant adjustment of the velocity and pressure profile allowed in the suspension in a simple manner. The spatial Arrangement of the volume flows at stream and dilution water Used in conjunction with valves in the form of dilution water flow valves each arranged on a central bore of the mixing device are so that the cross flow distributor for the dilution water adjacent to the mixing devices can be arranged. Long connecting cables as well as line transitions avoided, whereby deposits and spinning are also avoided as well as rapid variety changes are possible. By the position The valve is also more direct.
