Definitions

  • ABSTRACT A dry and wet heater for combined use, characterized in that said heater comprises a steam passage disposed inside a steam heating medium chamber and communicating with a steam supply source; and a pipe of a small diameter disposed inside said steam heating medium chamber and connecting a yarn introducing tube to said steam passage.
  • the present invention relates to a dry and wet type heater for combined use and more particularly to a heater applicable with false twisting machines and yarn twisting machines.
  • the conventional type heaters jointly using dry and wet heats have been of a type in which, as shown in FIG. 1 and FIG. 2, saturated steam is introduced into the upper portion of a dry heat type heater or into a yarn introducing tube. More specifically, as shown in FIG. 1, saturated steam 4 is introduced into a point above a dry heat type heater 3 provided with an electric heater 2 which is controlled by a controller 1. In FIG. 2, saturated steam 4 is fed into the yarn introducing tube 8 through which a yarn 7 passes, said tube 8 being surrounded with a heating medium of steam 6 that has been produced through evaporating heating medium by means of an electric heater 2. Insulating material is shown at 9.
  • Heaters of this type as shown in FIGS. 1 and 2 have the disadvantages that part of the steam 4 is condensed and adheres to the inner wall of the yarn introducing tube 8, thus preventing easy drainage of the water produced, and that the evaporation latent heat thereof tends to adversely affect the temperature of heat which is maintained constant inside the yarn introducing tube 8.
  • a method in which the saturated steam is first introduced into a heating device 10 before entering the yarn introducing tube and then the resultant superheated steam is fed into the yarn introducing tube as shown in FIG. 3.
  • the problem has still remained unsolved, because it was found to be extremely difficult to obtain superheated steam having little temperature variation throughout plural bobbins.
  • the object of the present invention is to overcome the aforementioned disadvantages inherent to the conventional heaters.
  • a heater utilizing in combination dry and wet heats, wherein a steam passage is provided inside the steam heat medium chamber which communicates with the yarn introducing tube by way of a small diameter pipe, whereby superheated steam may be fed into said tube so that each yarn introducing tube can be fed the superheated steam having uniform temperature variation throughout the yarn introducing tubes irrespective of the bobbins.
  • FIG. 1, FIG. 2 and FIG. 4 are longitudinal cross sectional views illustrative of the outline of the conventional type heater utilizing dry and wet heats in combination;
  • FIG. 3 is a plan view of another type of conventional heater utilizing dry and wet heats in combination.
  • FIG. 5 is a longitudinal cross sectional view of one embodiment of the present invention showing a heater utilizing dry and wet heats in combination.
  • a closed-type steam heating medium chamber is shown at 12 and contains a heating medium therein.
  • a yarn introducing tube 13 extends through and in the center of said chamber 12.
  • heating medium 14 Surrounding the lower portion of said tube 13 is heating medium 14 which is contained in said chamber 12 in a sealed manner, and an electric heater 15 is inserted into said heating medium 14.
  • indicated at 18 is a steam passage which extends through said upper connecting pipe 17 and communicates with another saturated steam supply source (not shown).
  • Communicating with said steam passage 18 is a pipe of a small diameter 19 which extends through said steam chamber 12 and has an end open in said yarn introducing tube 13, thereby providing means to feed the steam through the steam passage 18 into said yarn introducing tube.
  • Shown at 20 is a pipe connecting the upper connecting pipe 17 to the lower connecting pipe 16, said pipe 20 being adapted to return heating medium condensed in the upper connecting pipe 17 to the lower connecting pipe 16 and extending through the insulating materials 22 encompassed with the outer casing 21.
  • said steam passage should preferably be disposed in a vapor phase portion of the chamber 12. In this way it would not have as adverse an effect on the temperature of the heating medium as it would be if it were disposed in the heating medium 14.
  • shown at 23 is a yarn being heated.
  • the heating medium 14 will be heated and evaporated.
  • the evaporated steam thus produced will fill the steam heating medium chamber 12, and in turn the condensation latent heat of the steam will heat the yarn introducing tube.
  • the radient heat of the tube then heats the yarn 23 passing therethrough, thereby thermally setting the yarn.
  • a steam heating medium heater of a known type incorporating a controller (not shown) which is adapted to sense and respond to the pressure of the steam heating medium inside the closed steam heating medium chamber.
  • the temperature in the yarn introducing tube 13 can be used.
  • the temperature of the former may be controlled by means of steam heating medium to a temperature of the yarn introducing tube 13.
  • the saturated steam produced at the other saturated steam supply source (not shown) is fed into said passage 18 at a constant pressure, it will turn into superheated steam which, in turn, is delivered to the yarn introducing tube 13 via pipe 19 without being subjected to temperature changes, thereby causing the superheated steam to fill the yarn introducing tube 13 with the temperature of said superheated steam maintained equal to that of the yarn introducing tube.
  • the present invention provides a heater which comprises a steam passage disposed inside the steam heating medium chamber and communicating with a steam supply source; and a small diameter pipe which is connected to the yarn introducing tube, whereby the steam inside said steam passage may be turned into superheated steam, the temperature of which is accurately controlled by a device of a known type. Furthermore, the temperatures of the steam passage and the pipe can be controlled and maintained to that in the yarn introducing tube, thereby permitting superheated steam of a temperature equal to that in the yarn introducing tube to be fed into the latter through the small diameter pipe,'with the result that the yarn being treated can be subjected to stable wetness and heat effects, thus resulting in a high quality product.
  • the communication between the steam passage and the yarn introducing tube permits simultaneous delivery of the superheated steam to a plurality of yarn introducing tubes at a constant pressure and flow rate, as long as the pressure of the steam being fed into steam passage 18 is maintained at a constant value.
  • the present invention provides a heater utilizing dry and wet heats in combination, which can supply superheated steam to a plurality of yarn introducing tubes simultaneously at a constant temperature, pressure and flow rate, thereby producing high quality yarn and which is economical and compact in construction.
  • the heating device of the present invention is particularly applicable to high speed false twisting machines and yarn twisting machines.
  • a heater utilizing both dry and wet heat for heating yarn comprisingza steam heating chamber adapted to contain heated steam therein; a yarn introducing tube passing substantially through the center of said chamber; a steam passage lying within said chamber and being adapted to communicate with a steam supply source; a pipe connected between said steam passage at a point remote from said supply source and said yarn introducing tube, said pipe having a smaller diameter than the diameter of said steam passage, said ipe als o having a substantial length and lying complete y within said steam chamber, whereby steam passing through said pipe is subjected to the heat of the steam within said chamber.
