Definitions

  • ABSTRACT Heat treatment apparatus for synthetic fiber yarn including a plurality of spaced heating units, each unit including a vertically positioned closed vessel having a longitudinally positioned heater chamber. Liquid in the chamber, when heated, produces a heated vapor in the vessel for heating the exterior yarn contacting faces fixed thereon.
  • the heater chambers are interconnected such that a uniform temperature is maintained in each of the heating units.
  • the units are interconnected by flexible conduits or pipes to allow the spacing between the heating units to be conveniently adjusted.
  • This invention relates to heat treatment of synthetic fiber yarn and more particularly, to a heat treatment apparatus which includes a plurality of heat exchangers.
  • Each heat exchanger includes a vapor chamber and a liquid heating chamber. Means is provided in the heating chamber for heating a liquid contained therein to thereby cause a heated vapor to flow into the vapor chamber. The heated vapor transfers heat through the walls of the chamber to its exterior where yarncontacting faces are provided.
  • Conduit means connect an upper portion of each vapor chamber to the heater chamber and each of the heater chambers are connected by means of a flexible conduit. Accordingly, the
  • each of the chambers may be easily adjusted. Since the chambers are interconnected, uniform pressure and temperature may be maintained therein and the flexible conduit allows the relative position of each of the heating chambers to be conveniently adjusted without replacement of the connecting conduit.
  • Prior art liquid vapor heating devices having a plurality of vertical vessels with heat-contacting faces formedthereon generally include an upper pipe connecting each of the vessels to another for passage of the vapor.
  • a lower pipe is also provided and forms a heating chamber in which a heater element is provided to heat the liquid contained therein.
  • the upper and lower pipes through which the vapor and liquid in the vessels pass causes difficulty particularly in the lower communicating pipe.
  • the lower communicating pipe be of a fairly large diameter and it must extend a sufficient length from the side of each vertical vessel such that a pipe connected to the upper portion of the vapor chamber can be connected thereto. It is not only troublesome in its construction, but also in its operation.
  • saturated heat medium vapor for heating the vessels is condensed in the vessels and heat medium liquid in the lower communicating pipe becomes co-existent thereby cooling the vessels. As a result, temperature distribution throughout the vessels is not uniform;
  • a heat treatment apparatus for synthetic yarn including a plurality of heat exchangers or vessels each having yarn-contacting faces on the front and back walls and in which, when heat medium vapor produced in heating chambers associated therewith is introduced in the vertical vessel, the temperature of the vapor remains constant so that a uniform temperature is constantly maintained throughout each of the vessels.
  • Another object of the present invention provides a heating apparatus having a plurality of heat exchangers interconnected by means of flexible conduit means so that the space between adjacent vessels is easily adjusted even after the vessels are assembled.
  • each section includes a separate liquid heating chamber each of the heating chambers being interconnected to thereby maintain uniform temperatures in each of the sections.
  • a heater element is placed horizontally at one side of the bottom of each vessel.
  • the heating chambers are filled with a heat medium liquid to submerge a heater provided therein.
  • An upper or liquid phase portion of each of the heater chambers are interconnected by means of a flexible pipe or conduit.
  • the upper portions of each vertical vessel are also interconnected to an upper common pipe or conduit through flexible pipes and the upper pipe and lower pipe may also be connected with flexible piping.
  • FIG. 1 is a perspective view of a first embodiment of the apparatus of the present invention
  • FIG. 2 is a side view partially in cross section of the apparatus shown in FIG. 1;
  • FIG. 3 is a cross-sectional view taken along the plane Ill-III of FIG. 2;
  • FIG. 4 is a cross-sectional view taken along the plane IV-IV of FIG. 2;
  • FIG. 5 is a top plan view of the apparatus shown in FIG. 1;
  • FIG. 6 is a perspective view of an alternate embodiment of the present invention.
  • FIG. 7 is a side elevational view partially in cross section of the apparatus shown in FIG. 6;
  • FIG. 8 is a cross-sectional view taken along the plane VIIIVIII of FIG. 7.
  • the heat treatment apparatus of the present invention generally comprises a'plurality of closed vertical vessels or heat exchangers 1 for heat treatment of yarn.
  • Each of the vertical vessels include front and back yarn-contacting faces 2 and 3 respectively.
  • the yarn-contacting faces may be provided with a groove 3' therein as shown in FIG. 4 or alternately, may be of a flat configuration.
  • a heater chamber 4 is placed horizontally and extends rearwardly from one side of and along the bottom of each of the vertical vessels 1.
  • An electrical heater element 5 is provided in each of the heater chambers.
  • a heat medium liquid 6 is provided in the heater chambers and submerges the heater element 5.
  • the liquid is placed in the closed vessel after it has been evacuated to thereby form a closed system.
  • the vertical vessels and heater chambers are interconnected with one another through suitable piping or conduit; therefore, the liquid in each vessel maintains the same level.
  • the interior of each vertical vessel 1 and heater chamber 4 communicate with one another through a port 7.
  • each of the vertical vessels 1 is connected to a common communicating pipe or header 8 through connecting pipes 9.
  • the connecting pipe 9 extends from a side of the vessel near its upper portion and is of sufficient length to allow shifting the vessels 1 to the left or the right.
  • the back portion of each of the heater chambers are interconnected by means of a pipe 10.
  • This pipe is made of flexible material such as copper or the like so that the space between adjacent heater chambers and vertical vessels may be varied.
  • a narrow tube 11 connects the pipe 8 3 to the upper portion of each of the heater chambers 4 through which a condensed liquid from the vapor in the upper pipe 8 is returned to the heater chamber.
  • a number of such tubes 11 are provided so that the condensed liquid is dispersed in each of the heating chambers 4 to thereby avoid lowering the temperature of the heat medium liquid in any one of the chambers.
  • a bellows 12 of elastic material is provided at one end of a tube extending from a part of any one of the vessels. The bellows is preferably located on the vessel in an intermediate section of the apparatus. The bellows 12 is operated by variations of vapor pressure in the vessels and controls a switching mechanism connected between an electric source (not shown) and the heaters 5 in each of the heater chambers 4.
  • a thermocouple switching element may be provided on one or all of the vessels acting directly with the variation of. its temperature so as to keep the temperature of all the vessels substantially uniform.
  • the heater chambers 4 are connected together through the lower pipe and port 7, the liquid 6 is maintained at the same level in each of the heating elements. Heated vapor produced by heating the liquid6 with the heater element 5 flows through the upper pipes 8 and 9 from one vessel to the other. The vapor pressure in each vessel as well as the temperature therein remains uniform. Therefore, by controlling the vapor pressure in any one vessel, the temperature of all of the vessels can be maintained uniform.
  • the heat medium vapor produced in the heating chamber 4 immediately fills the vertical vessel 1 associated therewith through the port 7. Uniform temperature distribution suitable for heat treatment of the yarn can be obtained in all ofthe vessels. There is no lowering of the temperature as seen in the conventional yarn heat-treatment apparatus of prior art structures.
  • the utilization of separate but interconnected heater chambers for each of the vessels connected by flexible pipes allows the relative position of the vessels and its associated heaterchamber to be conveniently adjusted in a manner heretofore unknown.
  • a pipe 13 is connected between the upper portion of each vertical vessel 1 and the heater chamber 4.
  • a condenser 14 is provided along the length of the pipe 13 between the vertical vessel and the heater chamber.
  • Each of the heater chambers 4 are also connected to each other by means of flexible pipes 10 and 15.
  • Flexible pipe 10 as in the previous embodiment, connects the lower or liquid phase portion of each of the heater chambers.
