Definitions

  • the invention relates to a device for guiding a to be dried Fibrous web together with a porous support belt through a drying device with the features of the preamble of the claim 1.
  • the object of the D1 is the part free of the support band and the track the circumference of the deflection roller largely covered by a box.
  • a box is also called an external suction box.
  • Such an external suction box is used, among other things, in a single-tier dryer group used.
  • the support belt and the fibrous web continues to next drying cylinder.
  • the Zone where the support belt and fibrous web run off a drying cylinder a critical area.
  • the subject of the D2, from which the invention is based, is in the gusset a suction box between the drying cylinders and the deflection roller provided a suction chamber in the area of the pick-up zone and one Above the exhaust air collecting box designed as a deflection roller includes. Not in the middle of the support band wrapped zone of the circumference of the roll shell of the deflecting roller there is a pressure in the exhaust air collection box higher pressure while the intended connection to a suction line ensures that negative pressure along the straight paths of the support band is generated to keep the paper web in secure contact with the support tape to keep.
  • the invention has for its object this known device to be improved so that the disadvantages mentioned are eliminated and a particularly good running of the support band and fibrous web is guaranteed by the drying cylinder.
  • FIG. 1 shows an arrangement in cross section two drying cylinders 11, 12, a deflecting roller 10 and an external suction box 14.
  • the fibrous web (which is not shown here) lies on the drying cylinder 11.
  • the support band 15 presses them against the surface of the drying cylinder.
  • the fibrous web and support belt run around the deflection roller 10 around to the next drying cylinder 12.
  • the inside of this suction box is primary characterized by the two suction channels 18, 3.
  • the deflection roller 10 shown in Figure 1 is a so-called perforated or perforated roller.
  • about the holes 13 and the suction openings 2 in the external Suction box 14 flows the extracted air into the Suction channel 18 to the vacuum source 5.
  • the so-called pick-up zone is located on the suction duct 3 connected.
  • the sealing and squeegee 16 is so attached that they are essentially in the area is where the fibrous web and retaining wall 15 still rest together on the drying cylinder 11. This position has the advantage that there is a ripple the support band (possibly due to internal stress) can't train. This is essentially one given straight sealing line.
  • the sealing and squeegee 16 has the task of being entrained by the boundary air layer Redirect air masses. Then you will entrained by the boundary air layer of the cylinder 12.
  • the sealing strip 36 is in the area of the path the support belt from the drying cylinder 11 to Deflection roller 10 attached where purely geometrical Support tape and fibrous web no longer touch with the surface of the drying cylinder 11.
  • This arrangement of the sealing strip 36 ensures that with suction through the suction channel 3 and vacuum source 6 between the surface of the Drying cylinder 11 and the fibrous web a rear ventilation is possible. This results in point A. on the surface of the drying cylinder 11 where the Fibrous web actually lifted off the surface becomes.
  • This area is known in the professional world as a pick-up zone designated. This zone is covered by the sealing strips 16, 36 and the suction openings 32 are formed.
  • Another embodiment of the invention would be a zone-wise placed across the web direction Subdivision of the suction channel 3. Each of these Zones could then be a separate connection to one Have vacuum source, so across the width of the web the suction pressure can be varied.
  • Another configuration this solution is summarizing similar zones (e.g. peripheral zones) to one Connection for a vacuum source. This variant is of importance. For one thing, it can be essential that one is in the pick-up zone on the edges of one Fiber peat web must suck more than the rest Area. Also for transferring the so-called Ribbon (i.e. when threading a fibrous web through the dryer section) at least in this one A zone-by-zone suction is important.
