Definitions

  • the invention relates to a nozzle beam in a device for generating liquid jets, with which an entanglement of the fibers of a guided along the nozzle beam fiber web is effected.
  • baffle body The removal of the baffle body from the pressure distribution chamber is technically extremely expensive. Because the baffle body is firmly screwed into a bore in the pressure distribution chamber and can only be removed if previously the entire lower part of the nozzle beam is dismantled. But this has hours of interruptions in the production of water-needled webs result.
  • the nozzle bar is provided with an impact body, which is preferably arranged eccentrically in the direction of the flow bores in the pressure distribution chamber. It has been shown that the flow around the impact body is thereby uniform and less turbulence in the pressure distribution arise.
  • Fig. 1 shows the nozzle bar according to the invention.
  • the housing of the nozzle beam consists of an upper part 1, which is often bolted to the lower part 2 over the length from below.
  • the upper part 1 has two bores 3 and 4, of which the upper is the pressure chamber 3 and the lower the pressure distribution chamber 4. Both chambers are open at one end face and screwed liquid-tight on the other side. Through the existing there opening can be introduced into the pressure chamber 3, the pressurized liquid.
  • the two chambers 3 and 4 are separated by an intermediate wall 5. Over the length of the nozzle bar connect a large number of flow holes 6 in the intermediate wall 5, the two chambers, so that the liquid flowing into the pressure chamber 3 flows evenly distributed over the length in the pressure distribution chamber 4.
  • the Pressure distribution chamber is open at the bottom by a narrow slot, which also extends over the length of the beam.
  • the upper part 1 is firmly screwed to the lower part 2 and liquid-tight.
  • the tightness is effected by the O-ring 9, which rests in an annular groove of the upper part 1.
  • a spring projection 15 which is fitted in a corresponding groove of the lower part and holds with its outer edges, the nozzle plate by contact with the nozzle strip 12.
  • an annular groove is introduced, in which the O-ring 10 rests for sealing the nozzle strip 124.
  • a slot 11 is also mounted in the lower part, which is only very narrow in its upper portion and only a little more than the width of the effective nozzle openings of the nozzle strip 12 leaves open.
  • the pressure distribution chamber 4 is produced according to the invention by a bore in the nozzle bar housing.
  • the slot 8 is mounted, which is smaller than the cross section of the pressure distribution chamber 4.
  • the entering through the flow holes 6 liquid should be evenly distributed in the distribution chamber.
  • the volume of the pressure distribution chamber 4 and an impact body 13, which is held over the length of the pressure distribution chamber 4 between the bores 6 and the slot 8, serve this purpose.
  • the impact body 13 is held at a distance from the intermediate wall 5 and can be flowed around by the liquid on all sides.
  • spacers are repeatedly mounted on the baffle body over the length of the nozzle beam, which are advantageously welded to the baffle and open at the bottom. In this way, the liquid from the flow holes first meets the baffle 13, distributed in the distribution chamber 4 and then flows with the same pressure over the length of the beam through the fine holes of the nozzle strip 12th
  • the circular impact body 13 is not centric, but arranged offset in the direction of the flow holes 6.
  • This eccentric Arrangement causes the still free pressure distribution space 4 a calmer, lossless, streamlined liquid flow to the nozzle strip 12 is formed. The result is clean water jets, which can then transfer more energy to the web.
  • the baffle 13 Since in the device according to the invention the baffle 13 is not bolted to the nozzle beam, but is held in position only in the pressure distribution chamber 4 by spacers, it can be pulled out in its entire length from the pressure distribution chamber.
  • This arrangement also has the further great advantage that the impact body does not have to be secured by a conventional counterbore, which repeatedly leads to turbulence of the water jets and thus to disruptions of the laminar flow. Over the entire length of the impact body, the surface is now even and homogeneous without flow traps.
  • securing the baffle bar against twisting is not done by the spacers themselves, but e.g. realized by a tongue and groove construction on the front side of the baffle bar.
  • a disinfecting lance can be introduced into the pressure distribution chamber, which removes the settled microorganisms with a disinfectant solution or with hot water. After cleaning the pressure distribution chamber 4 and the baffle bar 13, this is again inserted into the pressure distribution chamber and closed with a lid.
  • the nozzle bar according to the invention with an easily removable baffle body allows uncomplicated cleaning and removal of the microorganisms located in the pressure distribution body, without the need for complete disassembly of the lower part of the pressure bar.
  • Fig. 2 shows the placed on the baffle spacers.
