Definitions

  • the invention relates to a twin-wire former for producing a fibrous web, in particular a paper, cardboard or tissue web, from a pulp suspension according to the preamble of claim 1.
  • twin-wire former is known from European Patent Application EP-A-0 933 473.
  • the twin-wire former has two endless screen belts, which together form a twin-wire zone. Inn in a first section of the twin-wire zone in which the two screen belts run over a dewatering element in the form of a rotating forming roller, the two screen belts together form a wedge-shaped inlet gap, which receives the fibrous suspension directly from a headbox attached at an angle to an imaginary first horizontal plane (" Gapformer ").
  • the two screen belts run with the fibrous web forming therebetween via further drainage elements, for example via a plurality of forming strips and / or at least one forming shoe, at an angle of 10 ° to 60 ° to an imaginary first vertical plane.
  • the two screen belts run via a first deflection device with a lower vertex and then over at least one machine-width separating device, in the region of one of the screen belts is led away from the forming fiber web and the other screen belt.
  • a second deflection device is arranged with an upper vertex, which at an angle of less than 60 °, preferably less than 40 °, in particular less than 25 °, to an imaginary second vertical plane down the screen belt, which carries the forming fibrous web deflects.
  • the two screen belts run upward at an angle to an imaginary second horizontal plane such that the upper vertex of the second deflecting device lies above the lower vertex of the first deflecting device.
  • a disadvantage of this known twin-wire former is that it has a large overall height due to the relatively large forming roll diameter, which may for example have a value between 1.5 and 2.5 m. This large height leads in particular in conversions to problems in terms of the hall or crane height and thus to increased conversion costs and maintenance or operating costs.
  • the upper vertex of the second deflection at least 50 mm, preferably at least 100 mm, in particular at least 200 mm, above the lower vertex of the first deflection is that the angle, below the two screen belts after the first deflecting run up to an imaginary second horizontal plane, a value between 10 ° and 90 °, preferably between 25 ° and 40 °, and assumes that the distance between the lower vertex of the first deflector and the upper vertex the second deflection device assumes a value between 1 and 8 m, preferably between 3 and 6 m.
  • the advantage is achieved that the running of the two filter belts not only extends in one direction with respect to the overall height, but is also partially formed in a contrary manner and thus the absolute height, especially in a conversion, significantly reduced.
  • the arrangement of the headbox under an angle to the imaginary second horizontal plane extending down angle no increase in height, ie the headbox does not increase the height of the Doppelsiebformers, since he is not directed component wise upwards.
  • the forming fibrous web is additionally due to the deflection in directed an angle to an imaginary horizontal plane in an S-shaped track guide.
  • the upper vertex of the second deflection device be at least 50 mm, preferably at least 100 mm, in particular at least 200 mm above the lower vertex of the first deflection device and that the angle between the headbox and the two be imagined Horizontal level assumes a value between 0 ° and 45 °, preferably between 0 ° and 30 °.
  • a felt decreases the forming fibrous web from the screen belt at a pickup point which lies above the lower vertex of the first deflection device and the pickup point comprises a press unit, in which the forming fibrous web is first passed through a first preferably double-felted press nip with a first press roll and a second press roll, after the first press nip with one of the felts is guided around the first press roll, then in a second press nip on a non-felted press roll is passed, and then at least one further single-felted press nip passes, follows.
  • this second twin-wire former according to the invention too, the advantages mentioned in the first embodiment result.
  • the pickup point lies at least 50 mm, preferably at least 100 mm, in particular at least 200 mm, above the lower vertex of the first deflection device.
  • so-called equal-pressure dewatering elements are arranged between the first deflecting device and the separating device, between which runs the forming fibrous web, encased between the two screen belts.
  • the forming fibrous web In order for the forming fibrous web to achieve the best possible formation, that is as uniform as possible fiber distribution, ensured, and this with the highest possible dewatering performance and the lowest possible energy consumption during the web forming process.
  • at least one stationary equal-pressure dewatering element and at the other wire belt at least one equal-pressure dewatering element is arranged on the one wire belt, which is adjustable by means of a selectable force yielding to the wire belt.
  • the DC pressure dewatering elements can be adapted in a lighter, time-saving and cost-effective manner to different operating conditions and to different pulp suspensions.
  • the constant pressure dewatering elements are designed as plates or as plate segments, since these forms can be manufactured and operated inexpensively.
  • the deflection of the screen belt is carried out such that the screen belt then runs substantially horizontally, wherein in a further embodiment of the second deflection another sheet forming device, preferably a hybrid former, is arranged downstream.
  • the screen belt advantageously runs at least 50 mm, preferably at least 100 mm, above the lower vertex of the first deflection device.
  • the second deflection device is preferably a suction roll, a shoe with strips or a shoe with strips and with vacuum application, since these elements mentioned belong to the prior art, thus increased reliability and low acquisition costs, possibly also low operating costs possess.
  • the overall height is reduced in such a way that no significant additional costs (rebuilding costs, maintenance costs, operating costs) arise during conversions.
  • the first deflection device is a closed roll, an open roll or an open roll with vacuum loading.
  • the separating device is designed as a vacuum cleaner and / or as a vacuum shoe.

  • the drainage at the deflection roller is greater than at the other rollers, that is, the roller diameter deflection roller is larger than the roller diameter of the forming roller and / or the roller diameter of the suction roller.
  • twin-wire former has a height in a range of 2 to 8 m, preferably 3 to 6 m.
  • twin-wire former according to the invention is also outstandingly suitable for use in a former conversion, since in this case existing structural conditions, such as hall measurements, must be taken into account and thus the former conversion should bring no further space requirement, for example by an increased overall height of the Doppelsiebformers to be installed ,
