Definitions

  • the invention relates to a nozzle bar with means for adjusting the working width and a method for adjusting the working width of a nozzle strip.
  • the nozzle bar is located on a device for producing liquid jets for treating fibers of a web guided along the nozzle bar.
  • the beam consists of an over the working width of the fibrous web extending upper part and a liquid-tight attached thereto lower part, wherein in the upper part over the length of the beam, a pressure chamber is arranged, the fluid under pressure, for example, the front side is supplied.
  • a pressure distribution chamber is provided after an intermediate wall, which is connected to the pressure chamber via disposed in the intermediate wall fluid flow holes, wherein on the lower part a nozzle strip is mounted with the holes for the nozzle liquid.
  • the nozzle strip ensures the production of water jets, which are generated with a pressure of up to 1,000 bar.
  • a nozzle strip is sheet metal strips about 1 millimeter thick and about 1 inch (25.4 millimeters) wide.
  • the length of the nozzle strip, which runs over the entire web width, is about 300 to 500 millimeters larger than the web width depending on the design.
  • the nozzle-provided length of the nozzle strip usually corresponds to the web width plus 50 millimeters.
  • the diameter of the holes in the nozzle strip is between 0.08 and 0.2 millimeters. The edge of a hole in the water inlet must be worked very precisely to ensure a cleanly discharged jet of water.
  • the jet of water should remain bundled until it hits the web, as it is the only way to get the full kinetic energy into the fabric of the web to be processed bring in and thus cause in the web an optimal change in position of the individual fibers or filaments.
  • the nonwoven is solidified in the desired manner and optionally also influenced in its structure.
  • a production plant for the treatment of fibers of a web guided along a nozzle bar must be able to operate so flexibly that it can process a wide variety of customer orders.
  • the goods to be produced may require a wide variety of working widths.
  • nozzle strips with corresponding hole widths are used. This has the disadvantage of high investment, since the production of the nozzle strips is very expensive.
  • the object of the present invention is to provide a nozzle beam and a corresponding method on a device for producing liquid jets for the treatment of fibers of a guided along the nozzle beam web, which allow easy and cost-effective adjustment of the working width.
  • the object is achieved by a nozzle bar according to claim 1 and a corresponding method.
  • the nozzle bar according to the invention is located on a device for producing finest liquid jets for hydrodynamic jet exposure of fibers of a run along the nozzle beam web and consists of an over the working width of the web extending upper part and a lower part, wherein in the upper part over the length of the nozzle beam a Pressure chamber is arranged, which under the. Compressive liquid is supplied, and in parallel to the lower part of a pressure distribution chamber is provided, which terminates in a liquid outlet slot. Below the liquid outlet slot, a nozzle strip and, viewed in the direction of flow of the water jets, an easily detachable so-called mask strip are mounted in a liquid-tight manner directly above it.
  • a nozzle strip with maximum jet width is used on a nozzle bar. Now, if a smaller beam width is desired, viewed in the direction of flow of the water jets before the nozzle strip, a mask strip is mounted, which covers the unnecessary nozzle holes in the outer regions of the nozzle strip.
  • An adaptation of the beam width to the working width for the web also has the advantage that only as much energy is used in the process as required. Otherwise, the energy consumption increases with the beam width.
  • Adapted beam widths also protect the web-carrying components and reduce the spray water in the system, which reduces the process water discharge from the closed water cycle.
  • the mask strip has a slot-shaped recess which is smaller than the length of the row of nozzle outlet openings of the nozzle strip, wherein the slot-shaped recess is arranged above the row of nozzle outlet openings in the nozzle strip, that part of the row of nozzle outlet openings is released ,
  • the masking strip is preferably made of a plastic, metal, ceramic or composites with rubber coating.
  • the necessary contour of the mask strip can be generated, for example, by means of a laser cutting method.
  • the mask strip is thus inexpensive to produce, and with a nozzle bar comprising a nozzle strip and an easily replaceable mask strip, the flexibility of the nozzle beam for different working widths is thus ensured in a simple and cost-saving manner.
  • Another advantage is that this type of embodiment of a nozzle beam can be implemented immediately, that is, without costly conversion measures, even on existing systems.
  • the housing of the nozzle bar in FIG. 1 consists of an upper part 1, which is bolted to a lower part 2 often over its length by screws, not shown from below.
  • the upper part 1 has along two bores 4 and 5, of which the upper is the pressure chamber 4 and the lower the pressure distribution chamber 5. Both chambers 4 and 5 are screwed liquid-tight at one end face by cover 6 and 7.
  • the pressure chamber 4 On the other housing end wall 15, the pressure chamber 4 has an opening 3, through which the liquid introduced under a pressure of up to 1,000 bar is introduced.
  • the two chambers 4 and 5 are separated by an intermediate wall 8. Over the length of the nozzle beam connects a large number of flow holes 9 in the intermediate wall 8, the two chambers 4 and 5, so that the liquid flowing into the pressure chamber 4 flows evenly distributed over the length in the pressure distribution chamber 5.
  • the pressure distribution chamber 5 is open at the bottom, by a comparison with the diameter of the bore of the pressure distribution chamber 5 narrow liquid exit slot 10 which extends along the nozzle beam and a nozzle strip 14 disposed below the liquid exit slot 10.
  • the longitudinal extent of the liquid outlet slot 10 is determined by the partial length of the nozzle strip 14, which is not covered by the mask strip 18 immediately in front of the flow direction.
  • the lower part 2 is screwed liquid-tight respectively by further cover 16 and 17.
  • FIG. 2 shows a detail not drawn to scale on the nozzle strip 14 and the mask strip 18 from FIG. 1 , X denotes the perforated length of the nozzle strip 14 and X 'the reduced length of the recess in the mask strip 18.
  • the vertical arrow indicates the direction of flow of the water jets.
  • FIG. 3 makes a section along the line C - C FIG. 1 with the view of the front side of the nozzle strip 14.
  • FIG. 4 a section along the line C - C after FIG. 1 shown with the view of the front side of the mask strip 18 with a recess 19.
