Definitions

  • a nozzle bar for generating liquid jets is known, for example, from EP-A-0 725 175. From the arranged in the lower part of the beam nozzle slot occur at high pressure of up to 600 bar, the water jets and act on the immediately below passing web, which is held by a pad. The water jets are acted upon below the pad by a suction, which should ensure the removal of the liquid.
  • practice has shown that not all sprayed liquid can be sucked off immediately, but a part of the goods, is reflected on the substrate and back splashes against the underside of the nozzle bar. From there, this liquid drips onto the web, which should be avoided.
  • a nozzle bar For jet exposure of the fibers is a nozzle bar and a liquid-permeable screen roller.
  • the nozzle beam consists of an over the working width of the web extending upper and a lower part.
  • a pressure chamber Along the upper part of a pressure chamber is arranged over its length, which supplies the liquid under pressure frontally.
  • the liquid collecting device is designed as a suction tube with a suction slot arranged along the lower edge of the nozzle bar.
  • the invention has for its object to optimize such a liquid collecting channel so that it completely absorbs the reaching to the bottom of the nozzle bar liquid immediately, including an emerging during spraying water mist.
  • the solution found lies in the fact that the liquid collecting device is designed as a suction tube with a suction longitudinal slot arranged along the lower edge of the nozzle bar.
  • the liquid should not only be collected, but immediately sucked along the whole beam. It is expedient to generate the negative pressure in the collecting device by means of the pump, which also ensures the negative pressure in the suction slot on the base.
  • the height of the suction slit should be made small, z. B. 1 - 5 mm. It is advantageous if this suction slot is only arranged at the end of a funnel and the funnel reaches at least with its underside up to, possibly even below the bottom of the nozzle beam. Now there is only little space because the product to be treated must be performed very close to the outlet of the water jet from the nozzle plate. This is especially true when the pad is an endless belt, a little more space is given if the pad is a screen roller, which leaves more space due to their curvature for a denser arrangement of the Saugtrichters.
  • the invention proposes a solution for this arrangement and special Training, which will be described in more detail in connection with the example in the drawing.
  • FIG. 1 a screen roller in cross-section with this associated nozzle beam according to EP-A-0 725 175 is shown schematically.
  • FIG. 2 also shows an enlarged detail.
  • the screen roller 1 are associated with two nozzle bars 2 and 3, one right above and one right next to it obliquely downward.
  • liquid suction devices 4, 5 are on both sides of the nozzle bar 2 tightly associated.
  • such a liquid suction device 6 is necessary only on the lower side, since the liquid hanging on the underside of the nozzle bar 3 runs in this direction along its underside.
  • the collecting device 4 consists of an approximately rectangular curved plate 7, which is open at the bottom of the box-shaped tube in a suction slot 12, but otherwise also closed at the end faces.
  • the interior of the box-shaped tube is connected to a pump 8, which may also be the suction slot 15, not shown in detail sets below the impinging on the wire roller 1 jets under suction and is common there.
  • the liquid collecting device 4 - 6 is bent from a along the nozzle beam 2, 3 extending sheet 7, the end surfaces 9, 10 to form the funnel-shaped longitudinal slot 11 partially overlap and run towards the suction slot 12 conically.
  • the suction slot 12 is formed by the inner end edge 13 of the end face 10 of the sheet 7 together with the but up to the corner edge 14 of the nozzle beam 2 extending end surface 9.
  • the liquid enters due to the gravity 1 and then drips onto the web 16.
  • the hanging on the underside of the nozzle beam droplets but also dissolve over its entire surface, so that for a complete discharge of this liquid can only help a strong induced draft, the on the suction slot 12 is effective. So that a corresponding negative pressure can be established, the suction slot 12 is only of a small height, such. B. 2 mm.
  • the lower end surface 9 extends to the corner edge 14, possibly also a little towards the center of the nozzle beam 2, depending on how much space therefor is available.
