Definitions

  • the invention relates to a roller for guiding a textile or similar flexible web, which has at least one cavity partially filled with a liquid heat transfer medium and to be evacuated.
  • the roller should preferably be designed or used for the thermal treatment of the web.
  • a device with such a roller is described in DE-AS 20 27 420. It is provided that the cavity is evacuated to the saturated vapor pressure of the heat transfer fluid at operating temperature and thus the heat transfer fluid is heated to boiling temperature during operation.
  • the known system is used to achieve high temperature constancy over the entire surface of the roll shell with the least possible manufacturing and operating expenditure. For this purpose, use is made of the fact that in a closed system a liquid which is in free exchange with its vapor phase is always in equilibrium with it and thus the temperature of the entire system is only a function of the saturation vapor pressure of the liquid.
  • the same treatment temperature can be preselected and regulated over the entire length of the jacket of the roller provided for the thermal treatment of the web in a simple manner by allowing the pressure of the system to rise to a desired value by supplying energy, and thus by the vapor pressure curve of the heat transfer medium reaches a precisely defined temperature.
  • the invention is based on the object of further developing the roll mentioned at the outset so that the advantages to be obtained by it can also be achieved with a lower pressure increase in the cavity enclosed by the roll.
  • the solution according to the invention consists in that the amount of heat transfer liquid contained in the cavity is matched to the cavity volume in such a way that the liquid evaporates completely in the cavity before a predetermined, maximum permissible vapor pressure is reached.
  • the amount of heat transfer fluid contained in the cavity should be matched to the cavity volume in such a way that the vapor pressure of the liquid until it has completely evaporated into the cavity reaches at most a fraction of the calculation security pressure (compare the regulations of the German Technical Monitoring Association) and that the pressure increase is limited to the value corresponding to approximately 3 times the reliability of the calculation.
  • the vapor pressure in the roller only increases up to a predetermined temperature or up to a predetermined pressure value, at which the entire liquid contained in the cavity is vaporized, along the relatively steep vapor pressure curve and from then on only the Change of state with constant volume follows.
  • constant temperature on the roll shell can only be guaranteed up to the temperature that corresponds to the vapor pressure when the heat transfer fluid is completely evaporated. It is therefore particularly advantageous to set the temperature corresponding to the complete evaporation of the heat transfer medium by specifying the amount of heat transfer medium used so that until the temperature is reached, heat treatments in which a high temperature consistency across the width of the web is essential, for example when drying a wet web, essentially are completed and that higher temperatures are only used in treatment processes in which the web also or especially from the outside, d. H. is heated from outside the respective roller. The roller then essentially only serves to guide the web and the temperature across the web width no longer has to be kept as extremely precise as during drying. This applies, for example, to fixing certain states of textile webs that are already dry, in particular in a hot flue, which may have a plurality of guide rollers according to the invention.
  • FIG. 1 shows a cross section perpendicular to the axis of rotation 1 of a roller, generally designated 2.
  • the roller jacket 3 encloses a cavity 4.
  • a quantity of heat transfer fluid 5 which is evacuated and to be closed after the evacuation. This is dimensioned such that it must be evaporated completely within the cavity 4 before a predetermined, maximum permissible vapor pressure is reached.
  • a web 7 is guided on the roller 2.
  • FIG. 2 shows a section parallel to the axis of rotation 1 of a treatment roller corresponding to FIG. 1.
  • the temperature should be kept constant with external and / or internal energy supply Q even if the web 7 to be treated occupies only part of the length 6 of the roller 2.
  • This goal can be achieved as long as the liquid 5 is in equilibrium with its vapor phase in the cavity 4.
  • the condition is met until the vapor pressure is reached, at which the entire liquid 5 has evaporated into the cavity 4. If the temperature rises further, the desired temperature constancy on the length 6 of the roller 2 no longer applies exactly, but for these temperatures it is assumed that the drying process is complete and the web 7 and roller 2 assume the temperature of an external treatment medium.
  • FIG. 3 A diagram of the pressure curve P within the cavity 4 of the roller 2 as a function of the temperature T is shown schematically in FIG. 3. As the temperature T increases in the direction of the arrow, the pressure P increases within the cavity 4 of the roller 2 along the vapor pressure curve 10. This results in a relatively steep increase in pressure P, in particular with water as the heat transfer medium. This increase would continue without the measure according to the invention along line 11, for example up to a pressure P K at a temperature T 1 , at which, for example, a fixing treatment textile material web is to be executed.
  • the amount of heat transfer fluid 5 within the cavity 4 is matched to the volume of the cavity 4 in such a way that the liquid 5 is to be completely evaporated into the cavity 4 even at the temperature T E before the pressure P K is reached, the The steep rise in vapor pressure on curve 10 ends, for example, at the pressure P E and the temperature T E corresponding to this pressure. Since the pressure increases only isochorically along the straight line 12 when the temperature rises further, for example up to the desired treatment temperature T i , only a relatively small pressure increase dP results when the temperature rises to the value T 1 .
