Definitions

  • the invention relates to a heatable and / or coolable cylinder with a rotatably mounted in a chair support axis and at least one with the stationary connection connected to the supporting axis for feeding and / or removing at least one heating and / or cooling medium the connector and the support shaft through, mixing the rotating Cylinder body, the support shaft and / or at least one with them rotating part on the one hand and the frame, the connection and / or at least one other stationary part on the other hand sealant are provided.
  • Such cylinders are for example in EP 0 499 597 B1 and the DE 197 00 139 A1 described.
  • the pressure is generally applied via springs, the contact pressure additionally by the vapor pressure prevailing in the cylinder is supported.
  • the aim of the invention is to provide a heatable and / or coolable cylinder to create the type mentioned, in the simplest possible way ensures a wear-resistant and reliable seal is.
  • the sealing means at least one between a respective rotating sealing surface and a respective stationary sealing surface arranged brush seal include.
  • a respective brush seal can, for example, consist of a bundle of Wires exist that are held together by a socket.
  • the Wires can in particular be made of metal, but also from another Material. While the frame is supported on a sealing surface, the other sealing surface is touched by the wire ends.
  • the Wire bundles are not only arranged sufficiently densely, they are also more wear-resistant than carbon seals. In addition, the wire bundle is compliant, so that it can be installed especially under tension can, which also causes temperature-related tolerances between the sealing surfaces can be compensated. Additional pressing devices are therefore no longer required.
  • the sealing means can comprise at least one brush seal, which is arranged between radially directed sealing surfaces.
  • at least one brush seal can also be provided be arranged between axially directed sealing surfaces.
  • At least one ring-shaped brush seal is expedient provided what is particularly given the presence of a respective rotating sealing surface is advantageous.
  • Cylinder has the support axis in the heating and / or cooling medium leading area on a cylindrical bore, in which a preferably serving as a protective tube, rotating with the supporting axis cylindrical Pipe is used, which is located outside of the supporting axis End area is surrounded by a stationary connection.
  • the brush seal can be between the outer surface of the end region of the cylindrical tube and the stationary connection be.
  • the brush seal can be between the lateral surface of the end region of the cylindrical tube and the stationary Connection be arranged.
  • the space between the support axis and the tube rotating with it is preferably sealed to the outside via the respective socket.
  • the sealing means comprising at least one brush seal can generally between the rotating cylinder body, the support axis and / or at least one with this rotating part on the one hand and the Chair, the connection and / or at least one other stationary Part on the other hand be provided.
  • the sealant can at least comprise a brush seal that between the support shaft or one with this rotating part and a stationary connection or a part connected to this is arranged.
  • At least one Brush seal provided under tension between the concerned Sealing surfaces is used.
  • the at least one brush seal to provide at least one other, different type of seal.
  • means are preferably provided around condensate in the area of a respective brush seal dissipate.
  • a cylindrical bore provided support axis also at least one for draining water, Steam and / or condensate serving stationary channel, which on the one hand flows back into the cylinder interior and on the other hand again is led to the outside via the relevant stationary connection.
  • Cylinder is one of the two channels and the other stationary Channel surrounding stationary ring channel.
  • the Supply of steam-serving channel provided as a stationary ring channel be.
  • one of the two Roller ends only one channel for the supply of steam passed through the supporting axis provided with a cylindrical bore, which opens on the one hand into the cylinder interior and on the other hand via the concerned stationary connection is led to the outside.
  • the additional channel or channels lead to a further simplification the entire seal against the rotating part or parts.
  • the support axis comprises at each of the two roller ends there is an axle stub.
  • the cylinder according to the invention is in particular a drying cylinder, Press roll or smoothing roll in a machine for manufacturing and / or Refinement of paper, textile or other fibrous webs can be used.
  • FIGS. 1 to 3 each have a stationary connection 4 provided end of a heatable cylinder in the form of a drying cylinder shown, the one rotatably mounted in a frame of a paper machine Has support axis 2, each at the roller ends as an axis stub is executed.
  • the stationary connection 4 is fixed to the chair and with the a support shaft 2 having a cylindrical bore 12 is connected in such a way that the heating medium through the connection 4 and the support shaft 2 can be supplied or removed. Act in the present case the supplied heating medium is hot steam.
  • the stationary connection 4 shown in Figure 1 serves the stationary connection 4 shown in Figure 1 on the one hand the supply of steam and on the other hand the removal of water, Steam and / or condensate.
  • the stationary connection shown in Figure 2 4 is only intended for the supply of steam.
  • the stationary connection 4 shown in FIG. 3 only serves for discharge of water, steam and / or condensate.
  • sealing means each comprise an annular brush seal 5 consisting of a bundle of wires exists, which are held together by a version.
  • the wires can be made in particular of metal, but also of a different material consist.
  • the cylindrical bore 12 the supporting axis 2 serves as a protective tube and rotates with the supporting axis 2 cylindrical tube 6 is used, which in the area of each Axial frustum of the support axis provided storage 10 before too high Protects temperatures.
  • the cylindrical rotating with the support axis 2 Pipe 6 is in an end region of outside the support axis 2 surround the respective stationary connection 4.
  • the brush seal 5 is against it immediately between the lateral surface of the end region of the cylindrical Tube 6 and the stationary connection 4 are provided.
  • the respective brush seal 5 is expediently under tension mounted so that it is sufficiently elastic to tolerances between the cylindrical tube 6 or the bushing 11 and the relevant stationary Compensate port 4. This will always be an optimal one Maintain sealing effect. They also bring, for example metal wires of the respective brush seals 5 in A significantly reduced comparison to the previously used carbon seals Wear with itself. The complex pressing of the seal a respective opposite sealing surface can thus also be omitted.
  • the cylindrical bore 12 provided support shaft 2 both feeding of steam serving stationary channel 3 as well as a discharge stationary channel 7 serving water, steam and / or condensate performed, both within the rotating with the support axis 2 cylindrical Tube 6 run and on the one hand open into the cylinder interior and on the other hand led to the outside via the stationary connection 4 are.
  • the channel 3 used for supplying steam is the other channel 7 surrounding ring channel provided.
  • the condensate accumulating in the area of the brush seal 5 the removal of water, steam and / or condensate serving stationary Channel 7 directed.
  • the removal of water, steam and / or condensate can be done on the opposite Cylinder end take place, for example according to FIG. 3 can be trained.
  • the condensate can be removed from the area of the brush seal 5 directly through the stationary Connection 4 to the outside.
  • the embodiment 3 shows a connection to the removal of Water, steam and / or condensate serving stationary channel 3 is provided.
  • the cylinder described is in particular as a drying cylinder, press roll or smoothing roller in a machine for manufacturing and / or finishing usable from paper, textile or other fibrous webs.
