Definitions

  • the invention relates to a headbox with a turbulence generator and a nozzle.
  • Such a headbox serves to generate a machine-wide suspension jet in a machine used to produce a material web.
  • the material web formed from the suspension can in particular be a paper or cardboard web.
  • a corresponding headbox is described for example in the document DE 101 50 951 A1.
  • the headroom of the headboxes can a. for example, be divided by slats.
  • the slats currently used are essentially designed as flat plates.
  • the quality of the paper or cardboard is significantly influenced by relative movements between the fiber suspension and the sieve (s).
  • the formation and the burst pressure improve to an optimum with increasing difference between jet and sieve speed (
  • Shaking trestles are sometimes used in paper machines for graphic papers in order to improve the formation by additional shear stress.
  • this now has the disadvantage that the formation changes periodically at twice the shaking frequency.
  • the shaking frequency f For example, 300 1 / min and the machine speed v, for example 900 m / min, the screen moves between maximum and minimum lateral acceleration by 0.75 m.
  • the invention has for its object to provide a headbox of the type mentioned, with the properties of the fibrous web produced, in particular paper or cardboard, which require increased fiber orientation in the cross-machine direction, can be improved without noticeably affecting the properties of benefit from greater shear stress on the fiber suspension during sheet formation.
  • At least one lamella provided in the nozzle space and / or at least one separating element provided in the nozzle space is provided with at least one guide vane, which impresses a flow component directed transversely to the machine direction in the fiber suspension in the nozzle space.
  • At least one guide vane advantageously has a height that increases in the machine running direction, as a result of which fiber deposits on the guide vane are avoided.
  • At least one guide vane can be provided on the top and / or on the bottom of the lamella or the separating element. Designs are thus conceivable in which at least one guide vane is provided only on the upper side, only on the lower side or both on the upper side and on the lower side of the lamella or the separating element.
  • guide vanes provided on the upper side and on the lower side of the lamella or the separating element are at least partially arranged directly one above the other.
  • various lamellae and / or separating elements and / or on the one hand a lamella and on the other hand guide vanes assigned to a separating element can be arranged at least partially directly one above the other.
  • a guide vane assigned to a separating element can also be offset at least partially in the transverse direction.
  • Guide vanes provided in superimposed planes can at least partially point in different or opposite directions with their section serving for deflection. In principle, however, embodiments are also conceivable in which guide vanes provided in superimposed planes point at least partially in the same direction.
  • guide vanes provided in one-lying planes alternately point in different or opposite directions.
  • a reversal of direction can take place from level to level, or an identical alignment of the guide vanes in question can also be provided for at least two successive levels.
  • cross-flows which are rectified or opposite cross-flows are generated in the various planes.
  • the division of the guide vanes can be chosen in particular as a function of the division of the turbulence channels of the turbulence generator. So the division the guide vanes correspond, for example, to an integer multiple or an integer fraction (... 3, 2, 1, 1/2, 1/3, 1 ⁇ 4, ...) of the division of the turbulence channels of the turbulence generator. The division of the guide vanes can therefore in particular also be equal to the division of the turbulence channels of the turbulence generator.
  • the guide vanes When viewed in the machine direction, the guide vanes can be aligned with the turbulence channels of the turbulence generator or offset in the transverse direction with respect to these turbulence channels. In the latter case, the offset can correspond, for example, to half the division of the turbulence channels of the turbulence generator.
  • the division of the guide vanes can also be selected independently of the division of the turbulence channels of the turbulence generator.
  • a respective guide vane is arranged and / or designed in such a way that there is no stowage point for the fiber suspension within the nozzle space.
  • the guide vanes can be arranged, for example, between turbulence channel gaps of the turbulence generator. An accumulation and / or deposition of fibers, filler, fine material, dirt and / or the like is thus avoided.
  • At least one horizontal lamella or a horizontal separating element is advantageously provided with at least one guide vane.
  • at least one vertical lamella is provided with at least one guide vane.
  • the lamella or the separating element can extend in particular from the turbulence generator into the nozzle space.
  • a respective lamella or a respective separating element is preferably designed such that forces introduced by the guide vanes are absorbed and applied to holding elements of the headbox, e.g. the turbulence generator, a side wall delimiting the nozzle space, a separate support and / or the like are released.
  • the headbox can be designed as a single-layer or as a multi-layer headbox.
  • the respective separating elements can in particular be fixed separating elements.
  • the number of fins used in the headbox can depend in particular on the number of turbulence channel lines of the turbulence generator or of the turbulence block adjoining the nozzle space.
  • the guide or deflection vanes can in particular also have a straight section running in the machine direction without a deflection effect.
  • An edge gap can be provided between a respective lateral nozzle wall and a respective lamella.
  • the outer guide blades can have a predeterminable distance from the respective edge of the lamella or the separating element.
  • the distances on the driver side and the drive side can be different or the same.
  • the intensity of the cross flow generated depends on the geometry of the blades (in particular the length, height and mutual spacing of the blades, the angle of the blades at the end in relation to the machine direction), the position of the blades in the nozzle space between the turbulence generator or that adjacent to the nozzle space Turbulence block and the orifice, the flow velocity at the turbulence generator or turbulence block being lower than at the orifice.
  • lamellae are installed in the headbox, as already mentioned, all or only some of them can be provided with at least one guide or deflection vane in the manner specified.
  • the slat ends can have any tip contour, e.g. B. have any conventional tip contour. Any slat suspensions and in particular any conventional slat suspensions are conceivable.
  • FIG. 1 shows a schematic plan view of part of a lamella 14 provided in a nozzle chamber 10 of a headbox 12, which extends into the nozzle chamber 10 from a turbulence generator 16 or turbulence block.
  • the flow or machine direction is indicated with “MD” and the machine direction with “QD”.
  • the lamella 14 is provided with guide or deflecting vanes 24, which impresses a flow component 26 directed transversely to the machine direction MD into the fiber suspension in the nozzle space 10.
  • the relevant flow component 26 thus points in the cross-machine direction QD.
  • a swirl or rotary flow is not generated here.
  • the guide vanes 24 are arranged in the region of the end 28 of the lamella 14 which is located downstream in the machine running direction MD.
  • the guide vanes 24 can in particular also be provided on a separating element, in particular a fixed separating element.
  • FIG. 2 shows, in each case a schematic illustration, different pairings of guide vanes 24 arranged on the top and the bottom of a lamella 14.
  • FIG. 2a a schematic plan view of part of the relevant lamella 14 provided with the guide vanes 24 is first shown again.
  • the bent active ends of the two guide vanes 24 arranged on the upper side or the lower side of the lamella 14 point in the same direction.
  • the respective guide vanes 24 arranged on the upper side or the lower side of the lamella 14 are offset in the transverse direction by an amount V.
  • FIG. 3 shows a schematic plan view of part of a lamella 14 with guide vanes 24 offset with respect to one another in the machine running direction MD.
  • the angle between the respective blade end and the machine direction MD is again indicated with. This angle can be at least partially different or also the same for the different guide vanes 24.
  • FIG. 4 shows a schematic partial representation of a headbox 12 with a plurality of fins 14 arranged one above the other, the guide vanes 24 of which alternately point in different directions from fins to fins at the relevant active end.
  • the guide vanes 24 can be provided, for example, in front of the slat end 28 (cf. in particular FIG. 3), in the area of this slat end 28 or at the slat end 28 such that the suspension flow is deflected only after the slat end he follows.
  • the guide vanes of fins 14 arranged one above the other can point, for example, in the same direction or alternately in different directions, or they can be arranged according to any other pattern (e.g.: + - +, ...), where "+” e.g. a redirection to the right and "-" a redirection to the left or vice versa.
  • Slats 14 with guide vanes 24 can be used, for example, together with slats 14 without guide vanes 24 (e.g. "without + - without” ).
  • the division of the guide vanes 24 can depend, for example, on the division of the turbulence insert and, for example, an integer multiple or an integer book of this division of the turbulence insert (..., 3, 2, 1, 1/2, 1/3, 1 ⁇ 4,. ...) correspond. If the turbulence insert and the guide vanes are divided equally, the vanes of the lamella can either be arranged in alignment with the outlet geometry of the turbulence block or be offset with respect to the latter. In the event of an offset, an offset corresponding to half the pitch of the turbulence insert is preferably provided. In principle, however, the division of the guide vanes can also be independent of the division of the turbulence insert.
  • FIG. 5 shows a schematic, sectioned partial representation of a headbox 12 with guide vanes 24 with a height h gradually increasing in the machine direction MD, thereby preventing fiber deposits on the guide vanes 24.
  • the guide vanes 24 can be provided, for example, on a lamella 14, as in the present case, or on a separating element which is in particular fixed.
  • FIG. 6 shows a schematic plan view of a lamella 14 of the headbox 12 according to FIG. 5 provided with corresponding guide vanes 24. 6, the straight sections 24 ′ extending in the machine running direction MD and the curved sections 24 ′′ of the guide vanes 24 can be seen in particular.
