Definitions

  • the invention relates to a steam-filled treatment chamber of the type corresponding to the preamble of claim 1.
  • the means for preventing drops from falling from the ceiling consist of an outside of the wall arranged heating by heating pipes which are subjected to steam, hot air or oil, for example.
  • the heating pipes are distributed in a gap that exists between the walls and an outer insulation layer.
  • the sheet metal wall adjacent to the steam is smooth.
  • the heating keeps the wall at temperature so that no liquid from the vapor can condense and no drops form.
  • the effort for this in the form of the heating pipes laid over the entire surface of the wall is considerable.
  • the invention is based on the object of designing a treatment chamber of the type in question in such a way that the formation of drops which impair the quality of the material to be treated can be prevented with relatively simple means without additional heating.
  • the "division" of the relief structure is intended to characterize the distance from "peak to peak” of the same. This distance should be small compare with the size of the drops to be expected with a smooth formation of the underside of the ceiling of the treatment chamber, the diameter of which is approximately in the range of 2 to 4 mm.
  • the purpose of the relief structure is not to allow large drops to form in the first place, but of course to cause the drops which form here, too, to detach before they have reached a harmful size, which in the appearance of the treating good, especially the colored textile web, is striking.
  • Forming the relief in a uniform pattern results in an operation that is uniform over the surface and facilitates production by embossing or in a similar manner.
  • the function of the relief structure is substantially supported if the individual elevations of the relief form peaks (claim 4), in particular are pyramid-shaped. Water droplets which form can adhere particularly poorly at the tips and fall off before a harmful size is reached.
  • the wall forming the ceiling should consist of a poorly heat-conducting material (claim 6), in particular of plastic (claim 7).
  • FIG. 1 shows a section through a damper equipped with the blanket according to the invention
  • FIG. 2 shows a detail from the ceiling area of FIG. 1 on an enlarged scale
  • FIG. 3 shows a partial perspective view from below of the relief structure according to FIG. 2;
  • Fig. 4 shows a plan view of the relief structure according to Fig. 3;
  • FIGS. 3 and 4 show the views corresponding to FIGS. 3 and 4 of another embodiment.
  • the damper designated as a whole in FIG. 1 serves for steam handling a textile web 1, which is guided in the sense of arrow 2 in vertical loops 3 through the damper, which are arranged through an upper row of deflection rollers 4 and arranged in a horizontal plane a lower row of deflection rollers 5 arranged in a horizontal plane are formed.
  • the damper 10 has the shape of a cuboid box, which has a water sump 6 on the bottom, which is heated by heating register 7 to form the steam atmosphere.
  • the ceiling 8 consists of a wall 11 facing the steam room 9, a heat insulation layer 12 upstream of this and an air gap 13 maintained between them.
  • the air gap 13 is maintained by spacers 14 arranged between the wall 11 and the heat insulation layer 12, which spacers consist of a wire mesh or of suitably shaped plastic structures.
  • the wall 11 is designed in a special way. It consists of an essentially flat sheet of plastic of approximately 5 to 10 mm thickness, which has a relief structure 15 on the side facing the steam room 9, which is explained in detail with reference to FIGS. 3 to 6.
  • the relief structure 15 basically consists of small elevations which are distributed close together over the surface of the wall 11 and which, when the wall 11 is installed, protrude downward on its imaginary flat underside.
  • the relief structure 15 'shown in FIGS. 3 and 4 consists of cones 16 arranged in a rectangular grid, the tips 17 of which face the steam chamber 9 and which can be seen from the cones 16 in FIG. 4 Raise underside 19 of wall 11.
  • the opening angle of cone 16 at the tip is 90 ° in the exemplary embodiment.
  • the elevations consist of four-sided pyramids with a square base, which rise from the bottom 19 of the wall 11, which is no longer visible here and is only imaginary, and again with their base surfaces located in this bottom 19
  • the angles measured between two opposite sides of the pyramids are in turn 90.
  • angles can also be smaller, so that the cones or pyramids become more pointed.
  • the division of the relief structures 15, 15 ', 15 is smaller than the diameter on a smooth surface of water droplets forming and falling, ie less than about 2 to 4 mm.
  • the division of the relief is ie the distance 18 from tip 17 to tip 17 is approximately 0.8 mm. Because of the square grid in the two exemplary embodiments 15 ' and 15 "these distances are the same in both directions.
  • the material of the wall 11 can be a thermoplastic, to which the relief structure 15 is impressed between rollers.
  • Plastic has a low thermal conductivity, which counteracts the occurrence of cold spots.

Abstract

Le plafond (8) d'un vaporiseur comporte une paroi (11) en matière plastique, du côté de la chambre à vapeur (9), laquelle présente sur la face du côté de la chambre à vapeur (9) une structure en relief avec des pointes (17), la distance entre chaque pointe étant inférieure au diamètre normal d'une goutte, c.à.d. inférieure à 1 mm. Sur le verso de la paroi (11) est prévu un interstice (13) maintenu par des écarteurs (14). A l'extérieur de l'interstice (13) est disposé une couche calorifuge (12).
