Definitions

  • the invention relates to an extended-nip press for dewatering a paper, board, tissue or another fibrous web in a machine for producing and / or finishing the same, consisting of a press roll with a flexible roll shell and a pressing element with a concave pressing surface which the roll shell for Forming an extended press nip presses to a cylindrical counter roll, wherein the diameter of the press roll is less than 1 m.
  • Such presses are often used in conversions and can replace conventional presses because of the small space required.
  • the object of the invention is therefore to reduce the burden of the flexible roll shell with the smallest possible space requirement of the press arrangement.
  • this object is achieved in that the diameter of the counter roll is less than 1, 4 m and the ratio between the length of the pressing surface in the web running direction and the diameter of the press roll is greater than 0.08 and / or the press roll counter-roll at the end of each roll at least 25 cm surmounted.
  • the diameter of the counter roll should not exceed a diameter of 1, 4 m because of the space required and the weight. He should, however - 2 -
  • the load on the roll shell of the press roll as a result of the deformation in the press nip area is further reduced if the diameter of the press roll is smaller than the diameter of the counter roll, as a result results in a lower convex curvature of the press nip in the web running direction.
  • the average pressing pressure in the press nip should be greater than 2 MPa, preferably greater than 3 MPa and in particular greater than 4 MPa.
  • the pressing surface in the web running direction has a length of more than 80 mm, preferably more than 100 mm. - 3 -
  • the pressing surface in the web running direction has a length of more than 140 mm, preferably more than 160 mm.
  • the advantages of the invention are obtained especially in presses in which the width of the press roll is less than 7.5 m, preferably less than 6.8 m and in particular less than 5.5 m ,
  • the reduced load on the roll mantle results in the press roll, i. her roll mantle only only at most 1, 4 m, preferably at most 1 m wider than the counter roll, i. whose lateral surface must be.
  • the roll mantle of the press roll should project axially beyond the mantle surface of the mating roll by at least 300 mm, preferably by at least 350 mm.
  • FIG. 1 shows a schematic cross section through an extended-nip press
  • FIG. 2 shows a side view of the extended nip press
  • FIG. 3 shows a representation of the pressure-pressure profile in the extended nip.
  • the extended press nip for dewatering a fibrous web 1, in particular a paper web in a paper machine, is formed by a cylindrical counter-roller 5 and a press roller 4 arranged above it.
  • the roller axles are mounted on both sides in a roller frame 10.
  • the fibrous web 1 passes through the press nip here by way of example together with a respective dewatering belt 2, 3 in the form of a press felt on both sides.
  • Dewatering belts 2, 3 take up a large part of the water pressed in the press nip from the fibrous web 1 and transport it out of the press nip.
  • the press roll 4 has a flexible roll shell 9 made of fiber-reinforced plastic, which is pressed by a hydraulic pressing element 6 with a concave pressing surface to the counter roll 5.
  • the pressing member 6 is formed as an axially extending press shoe.
  • the counter roll 5 has a diameter of 1 m.
  • the pressing surface of the pressing element 6 has in the web running direction 11 has a length L of about 160 mm, so that the ratio between this length L and the diameter of the press roll 4 is 0.2.
  • the thus-dimensioned extended-nip press is a very compact press unit and is therefore ideal for the replacement of conventional press units with a short press nip.
  • the axis of rotation 8 of the roll mantle 9 of the press roll 4 is offset by an amount a against the web running direction 11 to the press plane 7 passing through the supports of the press roll 4 and the mating roll 5.
  • the pressing pressure at the inlet of the press nip should gradually rise to a maximum and then drop suddenly from there to the outlet.
  • the width of the press roll 4 is about 6.5 m, which has a low deflection of the backing roll 5 result.
  • the roll mantle 9 Since the ends of the flexible roll mantle 9 of the press roll 4 are supported by cylindrical side windows 12, the roll mantle 9 requires a transition region from the concave shape of the press nip to the circular shape of the side window 12 shown in FIG.
  • This transition is also referred to as guy length h, b and corresponds to the length by which the roll shell 9 of the press roll 4 projects axially beyond the mantle surface of the counter roll 5.
  • This guy length li, I 2 can be the same or different lengths.
  • the press roll 4 projects beyond the counter roll 5 on both sides by the same length U, I 2 of approximately 30 cm, so that the press roll 4 is 0.6 m longer than the counter roll 5.
