Definitions

  • the invention relates to a spinning beam for the production of melt-spun filaments according to the preamble of claim 1.
  • the known spinning beams have spinneret packs which are arranged in rows on the underside of the spinneret.
  • spin-beam modules are arranged firmly next to each other, which are firmly connected to each other via pipes for the heat transfer medium.
  • the high space requirement of juxtaposed Spinnbalkenmodule depends on the mounting situation of the heating elements and pump, which can be maintained only with great effort and possibly replaced, as this sufficient space must be present between the spinning beam modules. An adaptation to an increased plant capacity is possible only with great effort.
  • the EP 2122019 B1 discloses an apparatus for melt spinning synthetic elements, wherein the spin pump is disposed on a separate pump support which is spaced from the housing of the spinning beam. This results in a very large distance between the pump and the spinneret, which is associated with the technological disadvantage of a longer residence time and makes a possible expansion of the system can be realized only with great effort due to the space required.
  • the US 6,083,432 shows a modular spinner, in which the individual components are difficult to access due to the vertical arrangement of spin pack and pump.
  • Each spin beam can only be equipped with a spin pack, with the boiler located outside of the modular assembly.
  • the US 6,736,624 discloses a support structure, below which the spin pack is arranged with the enclosing heating space.
  • Object of the present invention is to simplify the known spinning beam design, to allow easier access to the maintenance of the pump while compact design.
  • the object is achieved by a spinning beam for the production of melt-spun filaments, in which via an externally arranged extruder liquid plastic is conveyed to at least one pump, which promotes the liquid plastic to at least one spin pack with a spinneret, wherein at least the pump and the spin pack of a heat transfer medium to be heated, which is heated in a boiler.
  • the invention is characterized in that the pump, the boiler and an opening for receiving a spin pack are arranged in a modular assembly, which can be used and fastened one or more times in succession into a frame of a spinning beam.
  • the spinning beam can be expanded to include additional spin packages, so that the capacity of the system can easily be adapted to increasing production.
  • the modular assembly has a suspension which comprises at least two cross members.
  • the cross members are dimensioned so that they can be used in the frame of the spinner. On the cross members, the entire structure of the modular assembly takes place.
  • the cross member are connected to at least one heat chamber such that an opening for receiving at least one spin pack is formed.
  • the cross member and the heat chamber thus form a frame in which the openings for receiving the spin packs are arranged.
  • the connection of the cross member with the heat chambers results in a supporting frame to which all other components of the modular assembly can be fastened
  • the pump is lying and arranged transversely or orthogonal to a longitudinal side of the frame.
  • the pump can be maintained from an operation of the scaffold without major disassembly work is required.
  • a further improvement is achieved in that the boiler is arranged lying and transversely or orthogonal to a longitudinal side of the frame.
  • Both measures namely the horizontal arrangement of the boiler and the pump orthogonal to the longitudinal side of the frame allows a more compact design of the spinner, since no space requirement between the spinning packages or between the modules is required for the maintenance of both components. This is done exclusively at the operation of the scaffold, which has enough space for changing the long heating rods and the pumps.
  • the space required for the individual modules is reduced, whereby the lines for the liquid plastic can be designed shorter with a smaller pitch.
  • the lateral arrangement of the boiler also allows good access to the pump and to the monomer extraction.
  • the available space between the blower ducts is used for the boiler, so that no additional floor space is required for a separate boiler on the steel platform.
  • the arrangement of the boiler allows a small pitch, since the heating rods are about 90 ° to the spinning beam axis.
  • the pump and the boiler do not have to be arranged exactly at right angles to the longitudinal member. Also, a slightly oblique arrangement of, for example, 75 ° of the longitudinal axis of the boiler and the pump to the side rail, in which the components, such as the heating elements, exchanged via the service gear would fall under the term transverse or orthogonal.
  • the pump and the boiler between the spin packs are arranged removable, so that the distance between the spin packs is determined by the disassembly of the exchangeable components.
  • the arrangement of the spinning beam can be done in a very close distance from each other, which makes the overall system more compact and shortens the melt-carrying lines, which means the procedural advantage of shorter residence time for the liquid plastic.
  • the pump is driven by a shaft by a drive, wherein the drive is arranged on a frame outside of the spinning beam.
  • the pump is easily accessible and can be easily disassembled by loosening a few screws.
  • liquid plastic is passed via a flange connection by means of at least one pipe to the pump, wherein the pipes are arranged falling.
