Definitions

  • Such apparatus comprises a covered or an open vat in which the bobbins carrying the yarn to be dealt with rest upon a plate or diaphragm dividing the vat proper from its bottom compartment.
  • Theplate or diaphragm is fitted-with one or more apertures individually corresponding with the center of each bobbin, so that if the upper compartment of the vat containing the bobbins is filled with liquids while a vacuum is formed in the bottom compartment, the liquids are compelled to traverse the yarn layer, the washing and subsequent bleaching operations being thus obtained.
  • the said vats were heretofore open, viz. without any closing cover.
  • the present invention comprises a washing, desulfurating, bleaching and reviving vat for artificial yarns, characterized by the fact of having applied to it a cover provided with a hydraulic seal.
  • all the wet operations can be performed successively which are associated with the treatment of artificial yarns in the form in which they are delivered by the spinning operations, that is, the washing, desulphurating, bleaching and reviving steps in the treatment of such yarns can easily be carried out in the vat without loss 01 time or escape by evaporation of volatile liquids and perhaps deleterious vapors.
  • viscose artificial yarn as delivered by the spinning department still contains a large amount of carbon sulflde in condensed condition.
  • the ebullition point of the sulfide is as low as 42 C., large amounts of gaseous carbon bisulfide are developed during this operation, this gas being highly deleterious to the attendants health.
  • the hydraulically sealed cover obviates the said inconvenience without further ado, because it will sufiice to connect the cover to the atmosphere.
  • the hydraulically sealed cover prevents even the slightest portion of said gases from escaping and contaminating the surrounding air, even without using any ventilators. The air is thus maintained in completely sound condition, with a considerable saving in motive power, by omitting the ven- 20 I tilators.
  • Figure 1 shows a plant diagram in longitudinal elevation.
  • Figui 'ev 2 shows the same in elevated cross- I section!
  • the vat is provided with a cover having the peripheral edge thereof immersed in a liquid located ina channel about the upper edge of the vat so as to form a hydraulic seal, thus rendering possible during the washing, desulphurizing, bleaching and reviving operations the recuperation of the carbon bisulphide as a subsidiary and simultaneous optom compartment 4 of the vat.
  • the edges of the 45 cover 5 dip into the channel 6 filled with a liquid such as water forming the hydraulic seal.
  • pipe 1 serves to connect the space between the cover and the surface of the liquid with the out- 50 side, and may of course be led as far away as I desired from the vat.
  • the cover 5 is raised and lowered by means of the winch 8 and ropes 9 running over the sheaves l0 carried by the machine frame ll. Attached "to the cover 5 are 55 chains l2 supporting the frame l3, upon or from which the bobbin covers are suspended.
  • a particular feature of this vat is that recovery of the volatile liquids is made in the same vat without any auxiliary condensing apparatus because in order to recover carbon disulphide, for instance, it is sufilcient to have water circulation into the channel forming the hydraulic seal, and the condensed volatile liquids are collected in the water seal.
  • the vat provided with the described channel being filled with water forming a hydraulic seal with the peripheral edge of the cover also prevents the dispersion into the atmosphere of the volatile liquids where the vat is not completely filled with the liquid used for the treatment.
  • the bobbin covers l4 while forming a group which is raised and lowered together, are all independently'and individually suspended from the frames I 3 by means of rings similar to [5, l5,-and each bobbin cover is therefore naturally adaptedto individually become properly seated upon its respective bobbin when the frame from which it is suspended is lowered.
  • each bobbin is closed by a cover. It is no light hand work to apply and to remove these covers at the beginning and end of each operation.
  • a vat equipped for carrying out in the same an entire and complete series 10f consecutive operations such as the washing, desulphurating, bleaching and reviving treatment of artificial yarns in the forms in which they are delivered from spinning operations including the combination, with said vat proper and supporting means for supporting a plurality of bobbins within said vat, of a channel portion formed upon the upper edge of the vat, entirely surrounding the latter and capable of containing a quantity of fluid therein, a cover for .said vat having a downwardly directed peripheral edge which in closed position of the cover extends into the channel portion upon said vat and is adapted to be submerged in fluid located in the channel portion so as to form a hydraulic seal, a frame suspended beneath and within said cover as part of the equipment thereof, a plurality of individual covers for said bobbins secured as a group to said frame and adapted to individually engage the tops of said bobbins and close the same in closed position of said first cover, means for raising the first cover at will and thereby-simultaneously
