Definitions

  • the invention relates to a heat treatment device, in particular a dryer for unstable webs, such as textile webs or the like, in which gaseous or vaporous treatment agent consists of openings located in areas above and / or below the web, which are connected to inflow and outflow spaces. inflated onto the web and discharged from it.
  • the present invention is intended to avoid these disadvantages of the known devices and arrangements, and to solve the problem of creating a heat treatment device in which not only is the fabric correctly carried by the treatment agent without the webs striking the nozzle body, even with small ones, for a good treatment effect desired distances between the webs and the nozzle bodies is avoided, but at which no resulting flow components can occur in the web plane.
  • a heat treatment device of the type mentioned at the outset design the surfaces facing the web with the inflow and outflow openings as bottoms of nozzle bodies for the supply of the treatment agent, in which a multiplicity of inflows and outlets distributed over the entire floor surface Outflow openings are arranged in such a way that the same relatively small-area adjacent and successive, self-contained treatment units are formed in the direction of travel of the web as well as across the width of the web without significant resulting flow components along or across the web over several units.
  • a plurality of inflow openings are to be arranged in each treatment unit in a star or ring shape around a central outflow opening which is connected to the outflow space by means of a pipe which is guided through the nozzle body.
  • a plurality of outflow openings can also be arranged in a star or ring shape around a central inflow opening in each treatment unit, which are then connected to the outflow space by means of pipes passed through the nozzle body.
  • the inflow and outflow openings can be designed as preferably round bores or also as slots or other shaped openings in the bottom of the nozzle body. Particularly favorable flow conditions are achieved if the inflow and outflow openings are at equal distances from the assigned outflow and inflow openings.
  • treatment units lying one behind the other in the running direction of the material web should be offset from one another.
  • the treatment units can also be offset from one another transversely to the running direction. A combination of both options can also be provided.
  • the treatment units located above and below the web can be mirror images of one another, but they can also be offset from one another.
  • FIGS. 1 to 3 show different embodiments of treatment units 15 in which a plurality of inflow openings 12 are arranged around a central outflow opening 13. It is also within the scope of the invention that the inflow openings and the outflow openings are interchanged. In Fig. 1 they show as bores formed inflow openings 12 at a uniform distance to / open outflow 13, while in FIG. 2 they are arranged in a star shape, ie at different distances around the outflow opening. In Fig. 3, the inflow openings 12 are formed as slots which, unlike shown, can all be concentric around the outflow opening.
  • FIG. 4 and 5 show cutouts from the bottoms of nozzle bodies, which show how the treatment units 15 according to the invention are distributed on the bottom.
  • the direction of travel of the webs is indicated by arrows. It can be seen that in FIG. 4 the treatment units 15 are offset in the direction of travel of the web and in FIG. 5 transversely to the direction of travel of the web, a combination of these offsets is also possible.
  • the nozzle body 14 shown in FIG. 6 is a nozzle body arranged underneath the web and, overall, shows the arrangement of the inlet and outlet openings 13, as well as the air supply into the nozzle body and from there to the supply openings 12. Details can be found in FIG. 7, in which 10 nozzle bodies 14 with inflow and outflow openings 13 are shown above and below the web. The guidance of the treatment agent flows is indicated by arrows. It can be seen that the treatment agent is inflated from the interior of the nozzle body through the inflow openings 12 onto the fabric web and from there through the outflow openings 13, which are connected to the outflow space 17 by means of pipes 16 guided through the nozzle body, are discharged.
