Definitions
- the invention relates to a nozzle strip for the production of finest Fluid jets for beam interlacing of continuous or finite fibers in Webs of chemical or natural fibers in nonwovens, tissue, tissues or Knitted in a transversely extending to the leading web, in its length of the width of the web corresponding nozzle bar liquid-tight is stored, wherein generated in the nozzle bar, a fluid pressure up to 1000 bar is that of the nozzle strip against a wall provided with a flow-through slot of the nozzle beam, wherein in the nozzle strip for generating the liquid jets a variety of at a distance of 20 - 128 hpi, so very dense arranged side by side, in the diameter of 0.08 - 0.15 mm, so smallest Holes are introduced, being used as material for the individual nozzle body in Nozzle strip a carbide or a ceramic material, as well as sapphire, or a Material selected is the same or similar physical Has properties, and the individual nozzle body over its cross section of one Other materials such as stainless steel,
- a jet strip in general is z. B. from EP-A-0 725 175 known. He extends over a large working width and is generally made of a thin Sheet made of stainless steel with z. B. formed mechanically produced holes. This Nozzle strips or the holes introduced in them have one in practice tried and improved geometry, but in practice only one has short life. The wall of the individual up to 0.1 mm in diameter large nozzle holes must be extremely smooth, which is why the holes drilled or be punched.
- the geometry of the holes is of particular importance to the Formation of the water jet, which is why behind a the Water jet nozzle cross-section is a diffuse, conical part over the height of the nozzle hole adjoins, also around the formed water jet on the Do not make way to the end of the hole by rubbing against the walls of the hole rupturing.
- the holes are getting higher due to the practice desired water pressure and also because of the constant abrasion quickly in the Border areas unclean. This produces blurred, non-circular water jets that only bring unsatisfactory energy into the dynamic treatment of the web.
- nozzle strip is now according to the type described, with which the aforementioned problems are avoided.
- the water jets are now each generated by a single nozzle body, which consists of a very made hard material and only supported on the nozzle strip.
- Such nozzle body can, for. B. be formed of a sapphire on which the with a very smooth wall producible nozzle hole even after a long time Use with even high water pressure shows no signs of wear. Only the Mounting the individual nozzle bodies on such a nozzle strip is not easy. There is a particular danger that the nozzle body is not exactly perpendicular to Extension of the nozzle strip are aligned and that they are at a Bending stress of the long nozzle strip z. B. by stronger contact of solve this.
- the object of the invention It is to find a holder of the individual nozzle body, which is a safe Ensures alignment of the nozzle body in and on the nozzle strip and at the same time ensures that even with a bending stress of the nozzle strip it is impossible to jump off individual nozzle bodies.
- the respective nozzle body carrier consists of a cylindrical tube whose outside diameter is in the range of Nozzle body is wider.
- the sapphire should therefore after production of the smooth-walled nozzle hole, if necessary, followed by a sharply tapered cone exactly retracted into a nozzle body carrier and held there firmly.
- the constriction may be a diameter reduction of a bore for be the inclusion of the nozzle body.
- the nozzle body carrier can therefore from a cylindrical tube whose outer diameter in the region of the nozzle body is formed wider, with the head-like support area of the Nozzle body similar to a Allen screw a smaller in diameter Tube connects, which extends in the mounted state in the nozzle strip.
- the housing of the nozzle beam consists of an upper part 1, with the lower part of the second often screwed over the length of the screws 3 from below.
- the top 1 has along two bores 4 and 5, of which the upper pressure chamber. 4 and the lower is the pressure distribution chamber 5. Both chambers are at one end open and again screwed liquid-tight through the lid.
- the two chambers 4 and 5 are separated by an intermediate wall.
- About the length of the nozzle bar connect a large number of flow holes 9 in the insectsdung the two chambers, so that the inflowing into the pressure chamber 4 Liquid evenly distributed over the length in the pressure distribution chamber. 5 flows out, in addition to brackets 21 an impact body 20 is held.
- the Pressure distribution chamber is open at the bottom, by the opposite to the diameter the bore of the pressure distribution chamber 5 narrow slot 10, which also extends over the length of the beam.
- the upper part 1 is screwed firmly and liquid-tightly to the lower part 2.
- the tightness is caused by the O-ring 11, which is in an annular groove of the Upper part 1 is present.
- a spring projection 23 which fits in a corresponding groove 24 of the lower part 2 is and for the O-ring 12 has a repair groove 26 whose outer edges 25 are directed against the edge of the nozzle strip 14.
- an annular groove is introduced, in which the O-ring 12 for sealing of the nozzle strip 14 rests.
- a slot 13 in the lower part 2 introduced, which is very narrow in its upper part and only slightly more than the width of the effective nozzle openings of the nozzle strip 14 leaves open.
- Fig. 1 is here only in connection with the storage of the nozzle strip of Importance.
- the nozzle bar can also look very different, such. B. according to the DE-A-199 21 694.
- the nozzle strip 14 has a certain width for receiving the nozzle holes 30 and for the storage above the O-ring 12 is necessary.
- the individual nozzle body 31 are attached.
- the Reason for this wide opening is the exact design of the jet in the actual nozzle 30, which is very smooth in the walls and sharp-edged in the edge boundaries is formed, and then adjoining non-contact Extension of the nozzle jet until impingement on the textile material to be changed, like tissue or paper. This ensures a high-energy jet.
- Such a sapphire is held in a form-fitting manner in a nozzle body carrier 36.
- Düsen redesign 36 is similar to an Allen screw, so with a Head portion 37, which receives the sapphire centric, and a foot part 38, through which a further central bore 39 extends.
- the head part 37 is opposite to the Foot part 38 is formed wider in diameter and is supported by its annular Bearing surface 40 on the nozzle strip 14 from.
- the nozzle strip 14 are for interlocking Including the nozzle body carrier 36 and 38 for its foot part holes 41 introduced. Due to this construction, the sapphire is exactly aligned and permanently held in the nozzle strip 14 permanently.
- a groove 42nd milled in the dimensions only for the inclusion of the nozzle body 31, 36 is provided.
- the depth of the groove 42 then corresponds to the height of the head part 37 of the Düsen stresses as 36, to which reference is made to FIG. 4.
- the holes 41 in the nozzle strip 14 for the foot part 38 of the nozzle body carrier 36 are preferably two rows and according to FIG. 3 offset from one another and at a distance 43 ensures that the head parts 37 of the nozzle body carrier 36 do not touch, not even if the nozzle strip 14 in the one or other direction should be bent. This ensures one according to the assembly exact uniform arrangement of the sapphires in the nozzle strip 14th
