Definitions

  • This invention relates to apparatus for spin ning artificial filaments in which a coagulable liquid material is passed through a filtering medium and extruded into a coagulating medium to form a filamentary material therein.
  • the invention has particular applicability to the spinning of viscose rayon and may be substituted for corresponding portions of the conventional apparatus.
  • Fig. 1 is an elevation end view showing a compartment and a portion of its wall broken away :to better illustrate other portions of the apparatus supported therein;
  • Fig. 2 is an elevation side view in section of the apparatus
  • Fig. 3 is a fragmentary top view of the drainage portion of the apparatus
  • Fig. 4 is a pictorial view of the liquid container of the apparatus with portions of the walls broken away to illustrate parts thereof;
  • Fig. 5 is a section view of apparatus taken along lines VV of Fig. 2.
  • the apparatus of the invention comprises generally an assembly for extruding fine streams of a spinning liquid into a bath.
  • the assembly includes a container for the liquid bath, a spinneret and a rounder swingable out of the container with respect to a pivot, from a, position of suband a stationary filter for the spinning liquid, said spinneret, rounder,
  • the invention further includes an arrangement within the container by which the liquid of the bath may be deaerated as it enters the chamber, the level of the bath is regulated to a desired height, and buoyant material formed within the container is prevented from passing out of the container with bath liquid discharged vigorous and positive flowing of the solution.
  • a fixed bifurcate member 8 which provides support for a filter unit 9 and pivotable support for a swingable bracket ID.
  • the filter 9 is attached to the member 8 by a fitting l2 which has annular threaded portions which extend in threaded relationship with portions of the filter and the member.
  • the fitting I2 has a central passageway which is contiguous with the discharge passageway I 4 of the filter, best shown in Fig. 5, and contiguous also with a passageway [5 provided within the bracket l0.
  • Pivotable support for the bracket I0 is obextension I 9 of the fitting complementary to the recess clamp screw 20.
  • the passage l5 of the bracket It extends from the pivotal portion of the bracket to an enlarged 'interiorly threaded to accommodate a I 2 having a surface I1, and the end of a .35 from tube 40 and through the port 4
  • liquid flows out of the cell 38 into 39 through an aperture 45.
  • the aperture 45 is located near the bottom of the wall 46 so that any air or other gas mixed with the liquid flowing into the cell 38 may rise to the surface of the liquid while deaerated liquid flows downward and through the hole 45 into the coagulating region of cell 39.
  • the coagulated material consequently produced has a lower density than the coagulant and collects at the surface thereof in a fiat mass. It is highly desirable to prevent any of the coagulated material from overflowing into the coagulant return system on account or the likelihood of clogging overflow lines and possibly causing the overflow of the container 35.
  • Another problem attendant to the operation of spinning apparatus at relatively high bath temperatures is the separation and decomposition of oily materials from the bath solution into solid or curdy masses which affect the quality of the yarn and also that of the coagulant which is to be reclaimed.
  • the oily material tends to ,be concentrated in the top portion of the spinning bath liquid. Consequently, passage for spinning bath liquid to the overflow is preferably provided near the top of the chamber so that oily materials may be promptly carried out of the cell. Consequently, a screen or strainer E8 completely separates a region B9 of the cell through which the liquid leaving the cellmust pass.
  • the strainer is provided with vertical slots or apertures 55 which permit liquid'mater-ials and primarily the oil'c'ontained by the spin bath solution to leave the coagulating region while retaining the coagul'ated or other buoyant solid material.
  • the tube 63 maybe readily lifted from contact with its seat in the bo'ttom o'f the cell3l 'to facilitate the draining of the container 35.
  • An aperture 53 through the wall between the cell 31 and 39 is located near the floor of the container .z'approximateiy at the level of aperture '65, so that upon removal of the tube t3, substantial drainage of the entire container is accomplished.
  • the drain tube B3 comprises two members 55 and 58.
  • member '55 has .an inner surface in threaded relationship with an outer surfacecf the member '55 and may be adjusted longitudinally with respect "to member '56 to "establish the overflow level for the-container '35.
  • the lower end of the member 56 terminates in an conical portion 58 which seats on a complementary surface surrounding 'a threaded drain aperture of the container into which the threaded end of a drain pipe59 "extends.
  • the lower portion of the'member 56 is provided with radiallyextending lugs to, similar to the lugs 6
  • the chamber 31 is square with respect to a plane normal to the axisof the tube.
  • the members 55 and-56 of the tub “B3 may be removed and turned through increments of 90 degrees with respect to "ea-en other when adjusting the length of the tube.
  • the thread of the members has a fineness such that twisting one member with respect to the other through degrees does not change the length of the tube 43 more than approximately 0.01 of an inch.
  • the tube 53 may be readily lifted from the cell for draining the container or for adjusting the members to secure a desired change in the liquid level.
  • the filter 9 is constructed so that liquid is positively propelled through all passages thereof, and cannot collect in pockets in which it might undergo changes of viscosity or set-up as a result of ageing.
  • This result is obtained by providing an annular filter element 64 supported between a core 65 and an outer cover 56 for the filter.
  • the filter element is preferably a rigid structure which may comprise a porous metal such as 'sintered stainless steel, or other noncorrosiveimateri'al.
  • the desired spacing of the element between'the cover '65 and the core 65 is obtained by the thickness of flanges 69, 1B, and H whichmay, as shown, be a portion of a unitary structure including both the flanges and the 'element, or if'preferred, independent rings which support an unflanged element between the shell 66 and the core.
  • Clearances l2 and i3, 'exteriorly and interiorly of the element, respectively, are suiliciently small to insure appreciable velocity of liquid traversing these passages and to minimize the possibility for liquid to set up or to accelerate the clogging of the filter element 64.
  • the clearances 12 and 13 are such that neither clearance extends longitudinally further toward the end of the filter than the juncture'ofidie o er clearance with a duct or passage leading to the exterior ofthe filter.
  • the core 65 and the cover '66 of the filter are supported in concentrically threaded relationship on a base "portion It. Passa'geway id of the filter base it extends between apassageway 16 of the core 65 and the passageway of the .fitting 12.
  • the core 6'5 is preferably formed'with'anannular shoulder T8 for longitudinal positioning of v the filter element ii lbetween the shoulder and the surface 19 of the'filte'r base when the core -is screwed into the "base 15.
  • the cover, core, and base or manner maybe fabricated .from a noncorrosive metal or, as employed 'in'the conventional filter of rayon spinning equipmentffrom a rubber composition which may be molded and vulcanized into rigid non-resilient articles.
  • a magnetic member 82 press-fitted "or molded within the core 65 may be employed to further aid the removal of magnetically attracted material such as iron sulfide particles which are able to pass through the filter element.
  • the magnet 82 is preferably cylindrical and may be provided with 'end'portion's having a flange such as the flange '83 .so as 'toproviide a greater area to which magnetically attracted particles may become attached.
  • the end sur- 'face of the magnet maybe slightly concave to provide a depression 8'4 into which magnetically attracted impurities of the liquid to be filtered may collect.
  • the end portion '86 of the magnet being surrounded'by a' substantial th'icknesso'f non-magnetic material comprising the core, will have no appreciableeiiecton any material in the iiquid'being filtered either before or after the lid-- uid passes through the filter.
  • the magnetic member may take any form or shape which adapts it to the structure of the filter, Whether of the permanently magnetized or the electromagnetic type. If desired, a magnetic member may surround or be included within the structure of the cover 66. Access to the magnetic member 82 for cleaning is obtained by removal of the filter cover 68.
