Definitions

  • the invention relates to a machine for dewatering and drying a paper, cardboard or other fibrous web, to which a fibrous suspension formed at least partially from waste paper is fed, with at least two press nips, which are formed by two compressed press rollers each, the fibrous web with both sides one water-absorbing dewatering belt runs through the first and at least one other dewatering belt through the second press nip and a smooth impermeable transfer belt is guided through the second press nip on the side of the fibrous web opposite the other dewatering band, which transfers the fibrous web to a belt after the second press nip passes the following machine unit, the transfer belt running under the fibrous web, the receiving belt being a dryer fabric and the following machine unit being a drying group in which the fibrous web is meandering, is alternately guided over heated drying cylinders and suctioned guide rollers and at least one removal scraper is assigned to one, preferably the first drying cylinder of the following drying group, a pulper being located under the removal scraper and the
  • the fibrous web then adheres to the smooth jacket surface of the corresponding press roll after the second press nip and is then pulled open onto a belt hand over the following drying group.
  • the problem here is the transfer of the fibrous web by means of an open train, particularly at high machine speeds, and the complex transfer.
  • the object of the invention is therefore to simplify the transfer with the most intensive dewatering of the fibrous web, reliable web travel and the least possible rewetting.
  • the object was achieved in that the axis of the drying cylinder with the take-off scraper and the axis of the following suction-guided guide roller have a horizontal distance from one another which is greater than 80% of the sum of the radii of this drying cylinder and this guide roller. Since the fibrous web in the press section is constantly guided by at least one belt, the web guide is very stable even at high machine speeds. In addition, the transfer can take place web-wide through the press section at least up to the first drying cylinder of the following drying group, which also makes this very safe. Transferring only up to the end of the press section is problematic since the removal of the fibrous web from the transfer belt by means of a removal scraper can easily lead to damage to the transfer belt because of the contact pressure required.
  • the horizontal distance between the axes creates enough space for the pulper and to stably and safely remove the fibrous web from the take-off scraper into the pulper below, when it is transferred. This also reduces the risk that the fibrous web will not stick to the pulper when it is transferred Drying cylinder or the dryer fabric is continued, causing damage to machine elements. It is advantageous if the axis of the drying cylinder with the removal scraper and the axis of the following suction guide roller even have a horizontal distance from one another which is greater than 90% and in particular greater than 95% of the sum of the radii of this drying cylinder and this Guide roller is.
  • the fibrous web adheres to the smooth transfer belt, so that the relatively rough drainage belt opposite can be easily removed immediately, at most 200 mm after this press nip, and rewetting is prevented.
  • the transfer belt then safely guides the web to the belt of the following machine unit.
  • the transfer belt is then cleaned by a cleaning device which directs a cleaning fluid with a pressure of at least 50 bar onto the side carrying the fibrous web and comprises at least one scraper which follows.
  • the cleaning device directs the cleaning fluid even at a pressure of at least 100 bar, preferably at least 120 bar, onto the side of the transfer belt that guides the fibrous web. Because of the high pressure and to ensure adequate contact with the scraper, the transfer belt in the area of the cleaning device should be supported on at least one guide roller.
  • the extended press nip is advantageously formed by a cylindrical press roll and a shoe press roll, which has a flexible roll shell, which is pressed by a pressure shoe with a concave pressing surface to the cylindrical roll.
  • the extended press nip extends at least over 250 mm in the machine running direction and / or has a line force of at least 800 kN / m.
  • the transfer belt runs under the fibrous web. Sufficient adhesion of the fibrous web to the transfer belt is obtained if the latter has a roughness R Z in the machine direction of less than 12, preferably less than 10 and in particular less than 8 ⁇ m on the fibrous web side.
  • the distance between the second press nip and the delivery of the fibrous web to the receiving belt should be shorter than 2.5 m, preferably shorter than 2 m and in particular shorter than 1.5 m.
  • the fibrous web is guided by both belts of the respective press nip at least before the first, preferably before each press nip, over the longest possible guiding distance. Since the fibrous web adheres to both drainage belts with approximately the same thickness after the first press nip, the upper drainage belt of the first press nip should be guided away from the fibrous web during suctioning of the lower drainage belt.
  • FIG. 1 shows a schematic cross section through part of a paper machine with a press section and the following drying group for the production of packaging papers with a basis weight between 50 and 120 g / m 2 of a fibrous suspension formed at least partially from waste paper.
  • the press section shown comprises two press nips 2, 3, which are each formed by two press rolls 4, 5, 6, 7 pressed together.
  • the separate pairs of press rollers are carried at the ends of support parts in the form of a foundation which is supported on the machine foundation.
  • both press nips 2, 3 are elongated.
  • the press nips 2,3 are each formed by a cylindrical press roll 5,7 and a shoe press roll 4,6.
  • the shoe press rollers 4,6 have a flexible roller jacket, which is pressed by a pressure shoe with a concave pressing surface to the cylindrical press roller 5,7.
  • the aim is a length of the press nip 2, 3 in the machine direction 16 of at least 250 mm and a line force of at least 800 kN / m.
  • the fibrous web 1 runs through the first press nip 2 with a drainage belt 8, 9 on each side.
  • the fibrous web 1 is guided by an upper dewatering belt 10 and a lower, smooth and impermeable transfer belt 11 through the second press nip 3.
  • the drainage belts 8, 9, 10 are designed as water-absorbing press felts.
  • the upper dewatering belt 8 of the first press nip 2 takes over the fibrous web 1 from a forming wire 17 of an upstream former for sheet formation.
  • the lower dewatering belt 9 is brought into contact with the fibrous web 1, so that the fibrous web 1 is guided in front of the first press nip 2 over a longest possible guiding distance from both belts 8, 9 of the press nip 2.
  • the fibrous web 1 runs together with both dewatering belts 8, 9 before the upper dewatering belt 8 is led away.
  • the lower drainage belt 9 is suctioned in this area by a suction box 18 arranged underneath.
  • the fibrous web 1 is then transferred from the only lower dewatering belt 9 to the other, upper dewatering belt 10 of the second press nip 3.
  • the (other) upper dewatering belt 10 is led away from the fibrous web 1 after a maximum of 200 mm, which reduces the risk of rewetting, in particular with low basis weights.
  • the lower transfer belt 11 guides the fibrous web 1 until it is transferred to a belt 12, here a dryer fabric of a following drying group with only three drying cylinders 19 of a drying section for drying the fibrous web 1, alone.
  • the fibrous web 1 is supported by the dryer fabric, alternately guided in a meandering manner over heated drying cylinders 19 and suction-guided guide rollers 20.
  • a removal scraper 24 is assigned to the first drying cylinder 19 of the following drying group. This separates the fibrous web 1 when it is transferred from the drying cylinder 19 and then passes it into a pulper 23 located underneath.
  • the axis of the first drying cylinder 19 with the take-off scraper 24 and the axis of the following suctioned guide roller 20 are vertically offset from one another.
  • these axes have a horizontal distance 22 from one another, which here is greater than 95% of the sum of the two radii of this drying cylinder 19 and this guide roller 20.
  • the upper dewatering belts 8, 10 and the drying wire each loop around a suction-guided guide roller 21 during the takeover of the fibrous web 1.
  • the distance between the second press nip 3 and the delivery of the fibrous web 1 to the receiving dryer fabric is shorter than 1.5 m.
  • a relatively smooth surface of the transfer belt 11 with a roughness R Z in the machine direction 16 of less than 10 ⁇ m on the side carrying the fibrous web ensures sufficient adhesion of the fibrous web 1 to the transfer belt 11.
  • the fibrous web 1 may come into contact with the transfer belt 11 with a relatively high level of contamination.
  • the transfer belt 11 is intensively cleaned by a cleaning device 13 after the fibrous web 1 has been released.
  • This cleaning device 13 directs a cleaning fluid, here water with a pressure of at least 100 bar, onto the side of the transfer belt 11 carrying the fibrous web. Then the loosened impurities are removed from the transfer belt 11 by a subsequent scraper 14. Because of the high pressure, the transfer belt 11 is supported in the area of the cleaning device 13 and the scraper 14 on at least one guide roller 15.
