Definitions
- the invention relates to a nozzle bar on a device for generating liquid jets for jet interlacing the fibers of a fiber web guided along the bar, which consists of an upper part extending over the working width of the fiber web and a liquid-tightly attached lower part, wherein a. a pressure chamber is arranged in the upper part over its length, which the pressurized liquid z. B. is supplied at the front, and b. a pressure distribution chamber is provided in parallel with the intermediate wall and is connected to the pressure chamber via liquid flow bores arranged in the intermediate wall, and c. a nozzle plate with the holes for the nozzles is mounted liquid-tight on the lower part and d.
- the pressure distribution chamber at the area opposite the liquid flow bores runs out into a slot which opens out onto the bores of the nozzle plate, and e. in the pressure distribution chamber between the liquid flow bores and the slot, a baffle is arranged over the length of the slot, the f. over its length and over its cross section is arranged freely flow around in the pressure distribution chamber.
- a device of this type is known from EP-A-725 175. It is distinguished u. A. by a basically simple and compact construction, with which a good liquid distribution over the length of the nozzle bar and thus a uniform solidification pattern on the web can be achieved. This good distribution of the liquid over the length of the nozzle bar is achieved without any remarkable pressure losses, since an ideal flow pattern is made possible. There is nevertheless the task of also optimizing an advantageous device. An improvement is always desirable in the formation of the individual water jets. This is possible through the exact formation of the individual holes of the nozzle strip, which z. B. by another material of the nozzle strip according to WO 01/15812, namely by a nozzle strip or individual nozzles made of hard metal or the like. Because of the difficult processing or manufacture of such a nozzle strip, no improvement could be achieved with this measure. So there is the task to improve the formation of the nozzle jets on the Düsenbal ken.
- the solution according to the invention is that the known impact body is preferably arranged eccentrically in the pressure distribution chamber in the direction of the flow bores. It has been shown that the flow around the impact body is more uniform as a result, there are fewer eddies in the pressure distribution chamber, the liquid flow from the narrower outflow area of the liquid at the liquid flow-through bores and around the impact body, which is united by the eccentric arrangement towards the wall of the pressure distribution chamber Leaving more space for the subsequent equalization of the possible turbulence, allows a clean appearance of the water jets formed in the jet strip.
- an additional liquid equalization is provided before the pressure distribution chamber. This is e.g. B. possible by the liquid flow not only in the pressure distribution space, but also starting from the pressure chamber from a narrower flow area into a widening outflow area by the flow bores in the intermediate wall in the liquid outflow direction are initially narrow in diameter and then larger.
- a device of the type according to the invention is shown as an example in the drawing. Show it:
- FIG. 1 shows a section longitudinally through a nozzle bar as it is prior art
- FIG. 2 shows the view of the end face of the nozzle bar according to FIG. 1,
- FIG. 3 shows a section along the line C - C of FIG. 1 with the view of the lower part of the nozzle bar
- 4 shows a section across the nozzle bar according to FIG. 1 along the line A - A.
- the housing of the nozzle bar consists of an upper part 1, which is screwed to the lower part 2 many times over the length by the screws 3 from below.
- the upper part 1 has two bores 4 and 5, the upper of which is the pressure chamber 4 and the lower one the pressure distribution chamber 5. Both chambers are open on one end and screwed liquid-tight again through the covers 6 and 7.
- the pressure chamber 4 On the other end face, the pressure chamber 4 has an opening 4 'through which the pressurized liquid is introduced.
- the two chambers 4 and 5 are separated from one another by an intermediate wall 8.
- a large number of flow-through bores 9 in the intermediate wall 8 connect the two chambers over the length of the nozzle bar, so that the liquid flowing into the pressure chamber 4 flows out uniformly over the length into the pressure distribution chamber 5.
- the pressure distribution chamber is open at the bottom, namely through the slot 10 which is narrow in relation to the diameter of the bore of the pressure distribution chamber 5 and which also extends over the length of the beam.
- the upper part 1 is screwed to the lower part 2 firmly and in a liquid-tight manner.
- the tightness is caused by the O-ring 1 1, which lies in an annular groove 1 1 'of the upper part 1.
- the slot 10 encloses a spring projection 23, which is fitted into a corresponding groove 24 in the lower part 2 and with its outer edges 25 holds the nozzle plate by contact with the nozzle strip 14.
- an annular groove 12 ′ is again introduced, in which the O-ring 12 lies to seal the nozzle plate 14.
- a slot 13 is also introduced in the lower part 2, which is only very narrow in its upper region and leaves only a little more than the width of the effective nozzle openings of the nozzle plate 14.
- the lower part 2 is screwed together in a liquid-tight manner by a further cover 16 and 17.
- a groove 18, 19 is made at the level of the nozzle plate 14 held in the lower part, into which the nozzle plate 14 extends and can thus be easily taken for replacement after removal of the cover 16 or 17.
- the pressure distribution chamber 5 is produced through a bore in the nozzle bar housing. The chamber 5 is also closed at the bottom. For the exit of the liquid from the pressure distribution chamber 5 to the nozzle plate 14, the slot 10 is introduced, which is therefore smaller than the cross section of the pressure distribution chamber 5. The liquid entering through the flow bores 9 is to be distributed more evenly in the distribution chamber 5.
- the impact body 20 is held at a distance from the intermediate wall 8 and the liquid can flow around it on all sides.
- the impact body in the intermediate wall 8 is kept several times apart by means of screws 21 over the length of the nozzle bar. In this way, the liquid from the flow bores 9 first strikes the impact body 20, is distributed in the distribution chamber 5 and then flows with the same pressure over the length of the beam through the fine bores of the nozzle plate 14.
- the circular impact body 20 is not arranged centrally, but offset in the direction of the flow bores 9.
- This eccentric arrangement has the effect that in the still free pressure distribution space 5 there is a quieter, loss-free, more streamlined flow of liquid towards the nozzle strip 14. The result is cleaner water jets, which can then transfer higher energy to the web.
- the design of the flow-through bore 9 has the same reason, which is not made with a constant diameter into the pressure chamber 4, but in the area of the inner wall of the pressure chamber 4 the diameter is narrowed with the inflow opening 9 '. From there, the higher accelerated liquid flows into a larger space 9, which causes the resulting vortices to calm down. Also in the pressure distribution chamber 5, the liquid impinging on the impact body 20 flows from there into a larger space below the impact body 20, the water flow is laminated and acts on the nozzle strip 14 with higher energy.
