Definitions

  • the invention relates to a method for heating a godet and to a heatable godet with a rotatable roller jacket to be heated, forming a cavity, and with a heating device in the cavity of the roller jacket.
  • Heatable godets which contain the method for heating a godet by means of a vaporous medium, since a hermetically sealed space between the jacket to be heated and a radiator is partially filled with liquid, the steam of which is used for heat dissipation by means of condensation on the roller jacket ( e.g. DAS 1804 777).
  • the invention achieves the object procedurally in that the godet is heated by means of a gaseous medium and in that the medium inside the godet is in a substantially closed circuit on a heating device and on the inner wall of a rotating one to be heated Roll jacket is passed.
  • the object is achieved in that the heating device is provided with air guide channels in such a way that a free space of U-shaped cross-section, seen in the circumferential direction, is formed on both end faces of the cavity and between the inside of the roll jacket and the air guide channels, and that the roll jacket in this free space is provided with fan blades in such a way that when the roller casing rotates, the air forms a circuit flowing through the free space and through the air guide channels.
  • the fan blades can be arranged as radial fan blades on one end face of the cavity on the roller casing, so that the inside of the casing is free for possible favorable heat transfer structures such as e.g. B. grooves with different depths and / or helical arrangement.
  • the air channels can be on a stationary webs which are arranged coaxially in the roller jacket and which are encased in a jacket and are arranged radially and axially stretched on the carrier at least in the end part, as seen in the direction of flow, which provides the advantage that there is no swirl reducing the negative pressure in the flow at the outlet from the channels.
  • a stationary carrier 1 (FIG. 1) is fixedly arranged in a machine housing 2.
  • the bearings 3 take over the rotatable mounting of a roller shell 4.
  • the roller shell 4 comprises a cavity 5 (FIG. 1), in which on an annular end face 6 (FIG. 1) radially elongated fan blades 7 (FIGS. 1 and 2) are attached.
  • air channels 9 are provided on a support arm 8 belonging to the support 1 and extending coaxially to the roller jacket 4, which are arranged by webs 11 (FIG. 3-5) which are fixedly arranged in a radial and axially stretched manner on the support arm 8 and are encompassed by a jacket 10. be formed.
  • the webs 11 are firmly connected to the jacket 10.
  • This jacket 10 forms a free space of U-shaped cross-section, seen in the circumferential direction, in the cavity 5, which is delimited by the roller jacket 4 through the end face 6 of the roller jacket inner side 12 and a further cavity end face 13.
  • the end face 13 is part of the carrier 1 and forms with its continuation 14 and an L-shaped surface 15 on the roller shell 4 an air gap which connects the cavity 5 with the Ambient air connects the godet.
  • the carrier 1 with the bearings 3, the channels 9, and the roller jacket 4 with the fan blades 7 is collectively referred to as a so-called godet.
  • the fan blades 7 When the roller shell 4 rotates, the fan blades 7 on the one hand create an air circuit with a directional component in the direction K and on the other hand a directional component in the circumferential direction of the roller shell 4, from which a resulting flow direction K '(not shown) is formed.
  • the radii r are provided for fluidic reasons.
  • the elongated, radially directed fan blades 7 permit a reversal of the direction of rotation of the roller shell 4 without a deterioration in the flow characteristics.
  • the fan blades 7 can be designed in a certain direction of rotation as forward or backward curved fan blades with the basic change in the flow characteristics known per se from fan technology.
  • Heating elements which together with the webs 11 and possibly together with the jacket 10 form the heating devices.
  • the heating elements in the channels 9 are provided heating mats 18, which are circumferentially on the jacket 10 and on both sides of the webs 11, i.e. are arranged circumferentially in the channels 9.
  • the heating elements can be heating rods 20 provided in the webs 11.
  • the webs 11 are shaped accordingly, as shown in the figures mentioned.
  • heating spirals 19 can be provided in the channels 9 as heating elements.
  • the roller jacket 4 forms, together with an end wall 21 and a shaft 22, a unit which can be seen in the bearings 3.
  • the roll shell In order to give off the heat more intensively to the inside of the roll shell, it can be provided with grooves (not shown).
  • the groove depth can increase in inverse proportion to the decreasing temperature of the flowing air.
  • the grooves can also be arranged axially or helically or crossed helically.
