Definitions

  • the present invention relates to a heating roller assembly, for example for use in the heat treatment, at a definite temperature, of filamentary or flat articles, such as fibres or fabrics.
  • a heating roller assembly comprising a hollow cover, rotatable about an axis the cover having an internal surface whose total emission factor is close to that of a black body, a fixed element located inside the cover and having facing the internal surface of the cover, firstly a heating element surface whose total emission factor is close to that of a black body, and secondly a temperature sensing device "ice which is sensitive to heat radiation, adapted to control the heating of said heating surface and located outside the said heating surface and thermally insulated therefrom.
  • the form of the external surface of the cover varies according to the use to be made of this unit; and is generally cylindrical, but may be more complex. In order to avoid heat losses it is desirable that the cover should be externally polished. The heat inertia of the cover is advantageously reduced by making it as thin as possible.
  • the internal surface of the cover may be naturally black, or it may be covered with a lining which gives it a total emission factor close to that of a black body at the use temperature envisaged.
  • a lining may for example consist of matt black commercially available paints, or of nickel black, silver black or gold black obtained by vaporisation of the corresponding metal in a high vacuum. The total emission factor of these linings reaches, or exceeds, 0.90 at the use temperatures envisaged.
  • the heating element advantageously consists of an electrical resistance, but it is possible to use other devices such as a pipeline in which a heated liquid circulates.
  • the heating element is advantageously cast in a metal such as bronze or brass, so as to have as high an emission surface as possible.
  • the external surface of the heating element, facing the internal surface of the rotating unit has a total emission factor close to that of a black body, this being obtained either by imparting a striated appearance to this surface or by covering this surface with a coating having properties close to those of a black body, for example commercially available paints, nickel black, silver black or gold black, or by using the two methods conjointly.
  • the external surface of the heating element comprises the greater part of the external surface of the fixed element facing the internal surface of the rotating unit.
  • the temperature sensing device is integral with the fixed element and is thermally insulated from the heating part of this element "by an insulating material, for example asbestos, refractory cement, or diatomaceous earth agglomerates.
  • an insulating material for example asbestos, refractory cement, or diatomaceous earth agglomerates.
  • the information given by the tempcrature sensing device is transmitted to a control'device, of a type which is in itself known, for the corresponding heating element.
  • This control device may regulate the heat output so as to produce a definite temperature in the rotating unit, or to produce a given temperature programme.
  • Means are advantageously provided for the thermal insulation of the shaft carrying the'rotating unit from the heating elements.
  • an externally polished tube located between the heating elements and the shaft and/or a jacket of insulating material, for example asbestos, refractory cement, or diatomaceous earth agglomerates.
  • the fixed element thus also consists of several sections, each section comprising a heating element and a sensing device, and being linked to a heating control.
  • FIGURE 1 is a longitudinal section through a heating roller according to the invention
  • FIGURE 2 is a section along the line a-a of the roller of FIGURE 1;
  • FIGURE 3 is a section along the line bb of the roller of FIGURE 1;
  • FIGURE 4 illustrates a suitable control arrangement
  • the roller consists of a hollow steel cover 1, high gloss chromed externally, mounted on a drive shaft 2 which may be caused to rotate.
  • the said cover 1 has externally the shape of a cylinder whose axis coincides with the axis of rotation of the drive shaft.
  • the external diameter of the cover is 162 mm. and its length 310 mm.
  • the thickness of the cover, in the part which is used, is 4 mm.
  • Two annular electrical resistances 3 and 4 are affixed to a stationary portion or support 5 of the machine.
  • the radial play between the external periphery of the resistances and the internal cylindrical surface of the cover is about 1.5 mm.
  • the heating capacity of resistance 3 is about 1100 w., and that of resistance 4 about 650 w., the elements being partannular in cross-section (FIGURES 2 and 3).
  • the heating zone extends over a sector of 240", with the part 6 of the annular ring being formed from a. heat insulant consisting of diatomaceous earth agglomerate.
  • the drive shaft 2 is thermally insulated from the resistances 3 and 4 by a diatomaceous earth insulant 7 and a steel tube 8.
  • the emissive surface of the resistances facing the internal surface of the cover consists of stripes which gives that surface a total emission factor close to that of a black body.
  • the internal face of the cover is lined with a matt black commercially available paint, which confers to that surface a total emission factor of about 0.95.
  • Two thermistors 9 and 10 positioned at the surface of the diatomaceous earth zone 6, one being in section a-a and the other in section b-b, allow the heating to be controlled. These thermistors are located at the centre of the unheated zone 6, so as to be as sensitive as possible to the radiation emitted by the cover 1. These thermistors are linked to amplifiers 13, 14 (FIGURE 4) which provide the heating control of resistances 3 and 4, in a manner which is in itself known.
  • thermocouples 11 and 12 are placed alongside the thermistors 9 and and are linked to a temperature recorder 15.
  • the temperature of the cover is very close to that of the resistances.
  • the heating zone of the resistance extends through a sector of 240 and a thermal insulant extends through a sector of 120.
  • angle of the sector containing the thermal insulant may be varied. In practice, good results are obtained if this angle is between 15 and 180.
  • thermistors described in the above example are commercially available thermistors. It is for example possible to use thermistors in vacuum tubes made of glass which is transparent to infra-red.
  • the good heat transmission characteristics and the control in the example described allow the external temperature of the cover to be controlled to :0.S C. over the temperature range of to 220 C. It is obvious that the temperature range depends on the heat treatment carried out and on the characteristics of the fibres to be treated, and does not in any way limit the range of the invention described above.
  • the apparatus described assures simple and precise temperature measurement in any zone of the rotating unit and as a result allows simple and precise control of the temperature envisaged. Equally, it easily makes it possible to generate several temperature zones in the roller by juxtaposition of various fixed elements.
  • a heating roller assembly comprising in combination:
  • thermosensitive device which is sensitive to heat radiation, located in said external surface of said fixed member, but thermally insulated from said heating element;
  • control means controlling the heat of the heating element responsive to the temperature sensed by the temperature sensitive device.
  • thermosensitive device comprises at least one thermistor.
  • said fixed member comprises a plurality of slabs disposed axially adjacent one another, within said cover, each said slab including a heating element and a temperature sensitive device, which is sensitive to heat radiation, and means for controlling the heating of each said heating element responsive to the temperature sensed by the temperature sensitive device associated therewith.
