  • Such a dewatering machine is known, for example, from international application WO 00/31336 A1.
  • Twin-wire zone of this dewatering machine is preceded by a wedge-shaped converging and formed by the two screens space in which a headbox introduces the pulp with a first dry content.

  • the dewatering machine shown in Figure 2 of said document has the disadvantage that they only limited with a limited due to the respective limited drainage capacity of the chamber units Production speed, that is, Sieb beau can be operated. This is usually in a range of up to 200 m / min. Due to the reduced production speed of the dewatering machine also their production amount is also correspondingly low in a conventional machine width.
  • the process according to the invention makes it possible to achieve higher dry contents of the pulp due to improved, ie intensified dewatering of the pulp even at higher wire speeds.
  • the intensification of the drainage takes place on the one hand by their division into different phases, on the other hand by the type of drainage.
  • a drainage due to applied screen stresses among other things, also much gentler than a drainage due to the introduction of pressure pulses, they are now mechanical or pneumatic.
  • a greater amount of pulp can be produced with improved dry contents and improved properties.
  • "energy-consuming" drainage elements can be dispensed with, preferably even completely eliminated, and the required drive power is reduced by about 25% and the vacuum requirement to be installed compared with the known processes for dewatering pulp in a former about 40%.
  • the lower sieve for further dewatering of the pulp a lower wire tension of at least 20 kN / m, preferably at least 25 kN / m, in particular at least 30 kN / m yields
  • the upper sieve for further dewatering of the pulp an upper wire tension of at least 6 kN / m, preferably of at least 8 kN / m, in particular of at least 10 kN / m yields.

They run in a favorable manner - seen in Sieblaufraum of the lower sieve - in the first lower quadrant of the second guide roller preferably together. This again favors the achievement of the shortest possible dewatering machine and the avoidance of rewetting of the pulp.

Abstract

L'invention concerne un procédé d'égouttage de pâte de cellulose (2) sur une table de formation (3). Selon ce procédé, la pâte de cellulose (2) amenée par une caisse de tête (7) sur une toile inférieure (4) est guidée par un cylindre de renvoi (8) entre la toile inférieure (4) et une toile supérieure (5) pour former une zone double toile, au moins sur une certaine distance. Le procédé selon l'invention est caractérisé en ce que la pâte de cellulose (2) est préalablement égouttée au moyen de la toile inférieure (4) dans une zone d'égouttage préalable (9) disposée en amont de la zone double toile (6) dans le sens de marche (S) de la toile inférieure (4), et que la pâte de cellulose (2) est davantage égouttée dans la zone double toile (6) présentant un autre cylindre de renvoi (13), par les tensions (T.4, T.5) exercées par les deux toiles (4, 5). En outre, l'invention concerne une installation d'égouttage (1) pour pâte de cellulose (2), qui est appropriée à la réalisation du procédé selon l'invention.
