Definitions

  • the invention relates to a machine for producing a paper, cardboard, tissue or another fibrous web from a pulp suspension with a heated drying cylinder and a pressure hood comprising a dry assembly and having an input side and an output side guide roller for guiding the fibrous web together with at least a screen and an impermeable belt around the drying cylinder, wherein before the input-side guide roller in a gap formed by the impermeable belt and the at least one screen, a suction box for generating a negative pressure to the at least one screen is employed.
  • the intermediate belt is freed after leaving the cylinder of condensed water.
  • the web is passed around the cylinder between the intermediate belt and the metal belt while it is being cooled.
  • the heating of the metal strip takes place in the return loop, and the heated metal strip heats the outside of the surrounding the cylinder track in direct contact.
  • the document US 6,189,233 B1 relates to a dryer section of a machine for producing and / or processing a material web, in particular paper or board web.
  • the drying section consists of at least one heatable drying cylinder which is wrapped on a part of its circumference by a material web, a first support band and a sealing band, the material web contacting the surface of the drying cylinder.
  • This area is associated with a pressure hood, which is fed with a gaseous or liquid pressure medium.
  • a pressure is exerted on the drying cylinder.
  • the temperature of the gaseous or liquid pressure medium is lower than the temperature outside the wrap area.
  • a second support band between the first support band and the sealing strip is arranged.
  • the structure of the second support band is coarser than that of the first support band.
  • the water emerging from the material web is taken up by the support belts and led away.
  • a device for drying a fibrous web by means of a drying cylinder is known.
  • the fibrous web is guided below the drying cylinder below a sieve called a drying belt and an impermeable belt.
  • a chamber for removing the air is placed against the wire.
  • the impermeable band is cooled above the drying cylinder by means of water, so that the moisture evaporated from the fibrous web is condensed again in the sieve and subsequently removed therefrom by means of a suction device.
  • this object is achieved in that in front of the input-side guide roller in a gap formed by the impermeable belt and the at least one screen, a suction box for generating a negative pressure to the at least one screen is employed.
  • the invention is based on the realization of a possibility for conditioning a screen, which consists in evacuating the screen and the condensation of steam takes place much better in the absence of air. To ensure that there is no air in the sieve or sieves, the sieve or sieves are conditioned accordingly. Through the use of a suction device or by the injection of steam, a better condensation of the emerging from the fibrous web vapor is achieved on the cold side of the drying arrangement. The risk of rewetting the fibrous web during the drying process also decreases.
  • a steam blowing device for injecting steam into the at least one sieve is arranged in front of the inlet-side suction roll in a gap formed by the impermeable belt and the at least one sieve.
  • the steam blowing device for blowing steam into the at least one sieve can also be arranged directly in front of the latter in addition to the suction box in the running direction of the fibrous web.
  • a further steam blowing device for blowing steam is arranged in the at least one sieve.
  • the at least one screen is guided via a roller arranged in front of the input-side guide roller with a fixed suction zone and that the fibrous web is moved from a vacuum generated by the suction zone from another screen onto the at least one screen is transferred.
  • a suction device or a device for applying steam can be accommodated in the gap formed by the at least one screen with the impermeable belt.
  • a drying arrangement 1 ( Fig. 1 ) in a machine for producing a fibrous web 2 comprises a heatable drying cylinder 3, which is surrounded on its upper side by a pressure hood 4, in which a cooling medium flows to receive the heat emitted by the drying cylinder 3, which heats the fibrous web 2, wherein it is deprived of moisture at the same time.
  • the moisture emitted by the fibrous web 2 is absorbed by a fine-meshed sieve 5 moving around the drying cylinder 3 together with the fibrous web 2.
  • a further coarse-mesh sieve can be carried over the sieve 5. This is performed together with the wire 5 via a guide roller 6 and a guide roller 7 to the drying cylinder 3.
  • Both guide rollers 7, 9 can additionally support the drying cylinder 3 against its weight and the pressure hood 4.
  • a suction box 10 is mounted in the gap formed by the fibrous web 2 and the guided above her sieve 5 with the fabric 8.
  • the suction box 10 has at its front end a contour preferably adapted to the circumference of the guide roll 7 in order to prevent the re-entry of air and effectively in the sieve 5 or, if it is present, also from the coarse mesh sieve in him or the To suck them air contained and suck the fibrous web 2 to the wire 5, so that the fibrous web 2 during the wrapping around the drying cylinder 3 the better its moisture to the wire 5 emits.
  • two steam blowing devices or nozzles 11, 12 are arranged, which also support the dehumidification of the fibrous web 2 by blowing water vapor into the sieve 5 and, if present, into the coarse sieve.
  • the steam blower 12 the steam is blown onto the fibrous web 2.
  • a steam blowing device 13 is provided in the gap which the wire 5 and the band 8 form with each other. Also in this case, the air initially present in the screen 5 is replaced by water vapor, which condenses under the pressure hood 4.
  • the suction box 10 may have an injector device for generating negative pressure.
  • Fig. 4 In another embodiment of the invention ( Fig. 4 ) is also the steam blower 13 in the gap formed by the wire 5 and the belt 8 intended.
  • the wire 5 is guided over a deflection roller 14 which is equipped with a stationary suction zone 15. This sucks the fibrous web 2 from a sieve 16 on the underside of the fibrous web 2, so that it is passed together with the sieve 5 under the steam blower 13 in the direction of the drying cylinder 3.
  • the screen 16 is led away via a deflection roller 17 from the drying arrangement.
  • the suction box 10 can also be used in this arrangement.
