Definitions

  • the invention relates to a spinning head for melt spinning endless threads or the like made of, in particular, thermoplastic polymers according to the preamble of claim 1.
  • Threads in the sense of this application are understood to mean endless, linear structures which are continuously pressed out of spinneret plates and can be present, for example, as monofilaments or multifilaments, as ribbons, strands, bristles, spinning cables or the like.
  • Known spinner heads have interchangeable nozzle packs which are heatably inserted in corresponding receptacles in recesses in a closed heating box and whose melt inlet channel is sealed against the melt source under the action of a tension or compression screw.
  • the nozzle plates can have different hole patterns.
  • a nozzle package with a rectangular nozzle plate for producing spun cables for staple fiber or carpet yarn production or a pot nozzle with a circular nozzle plate for producing textile or technical continuous filaments with a nozzle plate Nozzle plate with different spinning titer or number of filaments can be used.
  • the structure of the spinning head remains essentially unchanged, while only the nozzle package or the holder with the nozzle package is replaced (e.g. DE-A 1660501).
  • the heat transfer from the heating box to the respective nozzle plate takes place via a housing receiving the nozzle package. This is pressed against the melt channel for sealing the melt distribution channel with pressure or tension screws which are supported on one side of the heating box.
  • the nozzle packet or its receptacle at most, rests with one of its end faces on a long wall of the heating box, while there are more or less large air gaps impairing the heat conduction on the other peripheral faces of the nozzle packet or its receptacle.
  • air gaps are undesirable, but inevitable because of the ease of assembly and due to manufacturing tolerances and different thermal expansions of the materials used for the heater box and nozzle pack or receptacle in the known heater box designs.
  • the heating box is constructed in two parts and consists of two mechanically independent, i.e. heating chambers adjustable relative to each other, the heating chamber expediently being fixed in place with the installation of the melt feed, the metering pumps and drives, the pump block, etc.
  • the end faces of the nozzle packs or the housings receiving the nozzle packs are installed between the longitudinal walls of the two heating chambers, which are at a distance from one another, and are pressed against each other without play.
  • the specified design of the heating box has the advantage that a large-area, metallic contact of the heat transfer surfaces is possible despite the unavoidable manufacturing tolerances and thermal expansion of the components.
  • the width of the nozzle packs is now independent of the previous one-piece heater box construction and the cutouts provided there.
  • the longitudinal walls of the heating chambers, between which the nozzle packs or their housings rest without play are designed as flat contact surfaces and are processed with a high surface quality, ie in particular with a low roughness depth, so that the heat conduction from the walls of the Heating chambers in the nozzle package or the housing for the nozzle package is favored by large-area metallic contact on both sides.
  • the housings for the nozzle packs are designed as heat-conducting blocks, which are particularly rectangular leaigen, plane-parallel side walls are equipped.
  • the play-free pressing of the two mechanically separated heating chambers and the nozzle packs or housing for the nozzle packs is preferably carried out by connecting elements that are subjected to tension, such as tie rods, stud bolts, tension spindles or the like, which are fastened in such a number in the longitudinal wall of the fixed heating chamber. that a sufficient surface pressure on the nozzle packs or their housings is guaranteed over the length of the spinning beam.
  • the tensioning screws advantageously run through the housing of the nozzle packs and / or through web-like spacers distributed along the edges and at certain spacing intervals over the length of the spinning beam, the length of which corresponds to the width of the Built-in nozzle packages or their housing is adapted.
  • Such an embodiment of the invention offers the advantage that the entire heating box can remain essentially assembled when changing nozzle packages or their housing, changing the spinning program, etc. This is advantageous, for example, with regard to the devices for the heating, the external heat insulation and the like, and simplifies the assembly work. After loosening the clamping screws, the NOZZLE PACKAGES or their housings can be easily removed and replaced upwards. On the other hand, with other spinner head designs, it is easy to remove the nozzle packages without changing the housing for cleaning or inspection purposes. Finally, an additional advantage is that poorly heat-conducting materials can be used for the spacers, so that the heating of the nozzle packs essentially only on their side surfaces facing the two heating chambers and not uncontrollable from the end faces.
  • both heating chambers can be self-contained and partially filled with an evaporable heat transfer medium. Electrical resistance heating devices or the like arranged in the heating chambers are switched on and off by temperature regulators in such a way that the same temperatures prevail in both heating chambers. However, it is preferred to heat both heating chambers to substantially the same predetermined temperature using a single, common heat source.
  • a vaporous, in particular condensable, heat carrier such as diphenyl or the like
  • a spinning head for producing threads from thermoplastic polymers by the melt spinning process is shown in cross section.
  • a plurality of nozzle packs 1 are arranged next to one another in series and form a spinning beam in the longitudinal direction, which can be expanded as desired.
  • the spinning beam comprises a heating box consisting of two mechanically independent heating chambers 2, 3, which is surrounded by an insulating jacket 4 to prevent heat loss and to protect the operating personnel, which is only divided in the area of the nozzle plates 5 of the nozzle packs 1 and there has a slot-shaped opening 6 having.
  • the heating box is essentially U-shaped and is supplemented by heat-conducting blocks 7, 8 in such a way that a heating box is formed which surrounds the other Eauruopen of the spinning beam, which ensures uniform heating of all components carrying the melt on all sides.
  • the heating box consists of the first heating chamber 2, which has a cavity for receiving the heat carrier, and which is L-shaped in cross section.
  • the first heating chamber 2 On its contact and support surfaces 9, 9 ', 9 ", which extend over the entire length of the spinning bar, it is machined in particular in such a way that a large-area, metallic contact is made with the melt-carrying components and heat-conducting blocks.
  • a block 10 On the horizontal leg of the heating chamber 2 a block 10 is exchangeably attached, which comprises a metering pump and the pump block with the melt distribution
  • This block can be replaced by a corresponding block which essentially changes when changing the spinning program, for example multiple or bicomponent spinning has the same external dimensions and is specially designed for this special purpose.
  • the pump drive shafts 11 are guided through insert cavities 12 through the cavity of the heating chamber 2 in a pressure-tight manner to the outside.
  • the melt is fed to the metering pumps through melt channels 13 (FIG. 2). These can lie in or between building blocks 7, which are designed as heat-conducting blocks.
  • the central melt distribution channel, to which one or more spinning beams are connected by stub lines 13 'and guided through the insulating jacket 4, is not shown in detail.
  • the modules 7 with the melt feeds are also exchanged if necessary when the spinning program is changed.
  • the second part of the heating box which is mechanically independent of the first heating chamber 2, comprises the heating chamber 3, which is designed as an elongated, rectangular hollow profile.
  • the height of the heating chamber 3 corresponds to the length of the ascending leg of the heating chamber 2.
  • the longitudinal walls 9 and 14 of the heating chambers 2 and 3 form contact heating surfaces for the front, plane-parallel housing walls of the nozzle packs 1 and are therefore present as flat surfaces which extend over the entire length of the heating chambers 2, 3. They are machined with a high surface quality and low surface roughness in order to achieve a large-area, metallic system and thus good heat transfer to the nozzle packs 1 to be heated.
  • the two heating chambers 2, 3 are, after installation of the nozzle packs 1, which - as FIG. 2 shows alternatively - for example a rectangular nozzle plate 5 'with rows arranged Nozzle bores 15 or preferably a plurality of pot nozzles with circular nozzle plates 5 ′′ can be pressed against the nozzle packs 1 or their housings without play by screw connections 16 with their longitudinal walls 9, 14.
  • the melt channels running in the nozzle packs 1 are sealed at the same time against the outlet channels in the pump blocks of the building blocks 10 (seal 17).
  • the tie rods or stud bolts 16 are screwed into the heating chamber 2, which is preferably arranged in a stationary manner, reinforcing eyes 18 or the like being provided in this, as shown in FIG. 2.
  • the tie rods 16 run through insert bushings or material reinforcements which are present in the heating chamber 3 and are sealed off from the outside in approximately uniform intervals, corresponding to the division of the nozzle packs 1. Between the heating chambers 2, 3, the tie rods or stud bolts 16 are guided in spacers 19, the length of which is equal to or less than the width of the installed nozzle packs 1. These spacers 19 are preferably made of a heat-resistant, but thermally poorly conductive material, such as a VA steel.
  • the nozzle packs 1 there are heat-conducting blocks 8 distributed over the entire length of the spinning beam, through which the upper part of the heating chamber 3 is connected in a heat-conducting manner to the building blocks 7 and the rising leg of the heating chamber 2.
  • the insulating jacket 4 can be opened at the appropriate point in order to be able to replace the nozzle packs 1.
  • the heating of the two heating chambers 2, 3 is carried out by a liquid or vaporous heat transfer medium according to the process engineering requirements of the polymer to be spun.
  • a condensable, organic heat transfer medium such as diphenyl
  • Both heating chambers 2, 3 are connected in parallel with regard to their heating and are supplied with saturated steam by a common steam generator.
  • a flexible line 22 (metal hose, compensator line or the like) is preferably used to connect the inlet connections 20, 21 of the heating chambers 2, 3, through which changes in the distance between the heating chambers 2, 3 can easily be compensated for when converting the spinning heads 1 or the spinning beam.
  • the heating of the two heating chambers 2, 3 can also take place in a different way, as long as it is only ensured that both heating chambers 2, 3 are heated to substantially the same temperature and remain at this temperature.
  • FIG. 3 shows a modified embodiment of a spinning head according to the invention in cross section and Fig. 3 a shows in detail the top view of a nozzle housing 27 for receiving a plurality of pot nozzles.
  • a nozzle housing 27 for receiving a plurality of pot nozzles.
  • the spinning beam consists of the two side parts designed as heating chambers 2, 3, which are screwed together by tension markers.
  • Clamping bushings 28 are welded into both side parts so that the cavities of the heating chambers do not deform when clamped with the nozzle housings 27.
  • a nozzle housing 27, which is shown in a top view in FIG. 3 a, consists of a cuboid into which through holes 29 are made at intervals. Between the through holes 29 there are transverse bores 30 through which the tie rods 16 or tension screws 16 are inserted during the assembly of the nozzle housing 27. Because of the high temperatures and the stress caused by the melt pressure during the operation of the spinning head, this fastening is given preference over a screwing of the nozzle housing 27 on both sides, in which the transverse bores are provided Threads are provided.
  • the distributor block 31 has an extension 32 with an external thread 33.
  • the nozzle package can be screwed onto the attachment with an appropriate internal thread.
  • Other types of fastening such as a bayonet lock or the like, can also be used. It is only necessary to ensure a good seal between distributor block 31 and nozzle pack 1. In the example shown, this is effected by the piston 34, the membrane 35 and the seal 36 (see, for example, US Pat. No. 3,891,379).
  • the melt metering pump is finally attached to the distributor block 31.
  • the insulating jacket and the connections and other devices for heating the heating chambers 2, 3 have been omitted. However, it goes without saying that these are available.
  • the heating box according to the invention with two mechanically separate heating chambers therefore has great technological advantages on the one hand because of the avoidance of air gaps and because of its high flexibility with regard to assembly and maintenance, on the other hand, offers great advantages for the manufacturer and the man-made fiber manufacturer.
