Definitions

  • the invention relates to a steam-heated roller in the preamble of the claim 1 described genus.
  • large means a diameter of at least 1,000 mm.
  • rollers are preferably heated from the inside by means of fluids Heat transfer medium, preferably with water, steam or thermal oil.
  • Heat transfer medium preferably with water, steam or thermal oil.
  • Increasing the surface temperature of the rollers either enables their function, by evaporating the moisture in the drying cylinders Paper web causes or promotes its function because the water in the Press at higher temperature and reduced viscosity more easily from the Can squeeze out paper web or because the plasticizability of the paper fibers increased at elevated temperature, making them easier to smooth out.
  • rollers cylindrical design If steam is used for heating, these are usually rollers cylindrical design.
  • the steam is usually in the interior of the roller cylinder passed where it condenses on the inside.
  • the condensate is over a Siphon led out of the roller.
  • roller wall cannot be as thin as desired run what a good heat conduction of the heating energy to the heat transfer medium would be desirable.
  • the above-mentioned disadvantages could be partially with the so-called peripheral drilled rollers can be overcome.
  • the fluid heat carrier flows - Water or thermal oil - through axially parallel bores just below the roller surface.
  • the way to conduct heat from the heat transfer medium to the roll surface could be reduced significantly.
  • German utility model No. G 93 06 176.5 has also been proposed as steam in peripherally drilled rollers Use heat transfer and so some of the disadvantages of water or Avoid thermal oil.
  • this implementation poses in the transfer large steam-heated rollers according to the principle proposed some problems.
  • the distribution of the heating steam is also as in this utility model has been proposed not to be realized in this way with large rolls.
  • Diameter increases the number of peripheral bores so that they no longer can be individually connected to the central drilling in the pin. Any collection spaces in the tenons or in the roll body or between both also forbid, because then the prerequisite for not applying of the ASME code (diameter ⁇ 150 mm) would no longer exist. But also if this doesn't matter, gathering rooms from which the connection should be made the peripheral holes could be done with strong pressure caps against that The inside of the roller must be closed if this is to remain free of pressure itself.
  • the advantage of such a roller according to the invention is in particular that the central bore of the roller body is kept completely free of heating steam, whereby there is no need for them to comply with the relevant regulations keep less than 150 mm in diameter, any more Take measures to prevent the prescribed flow area gets too big.
  • Another advantage is that the branching according to the invention the connecting bores now without a substantial weakening of the roller body or the flange pin distributes the steam to all peripheral Bores, especially with larger dimensions with a large number such bores is possible.
  • the proposed roller it is designed such that that the connecting holes in a driver-side flange of the roller are arranged, which is advantageous in that the short Flow path for the heating steam to its destination only small Heat loss during transport.
  • a roller according to the invention can be designed so that the connecting bores from the central hole in a first flange spigot to everyone branch out to the second peripheral hole, while the neighboring ones lying in between Drilling through passages in a second opposite Flange pins are connected.
  • a connecting bore is from the Central bore branches to four mouths of the peripheral holes.
  • connection bores are simple to produce feasible by suitable drilling of the flange pin, while by a suitable arrangement of the various sub-holes of the connecting holes Wide branching of the first hole starting from the central hole possible becomes. Since the individual holes within relatively large areas of the axial and radial angles are freely selectable, it can be ensured that despite a Large number of holes in the peripheral flange area no substantial weakening of the flange takes place. Furthermore, the mouth of the first hole which starts from the central bore of the flange and on the inside in the central bore of the roller body opens, there to seal easily because of space required for this inside the roller is not required for further components and is not under pressure or with a damaging seal Medium is filled.
  • At least one ring-shaped collecting space for the accumulating in the bores Condensate provided.
  • the steam-heated roller may have siphons that make up the plenum for draining off the condensate and any blow-by steam with the mouth areas of the peripheral bores at their ends in Connect flange spigot. This is a quick and effective removal of the Condensate ensured, the amount of condensate in the roller is extraordinary remains low.
  • the collecting spaces in the first and second flange journals can hold condensate be connected to one another by axially parallel return bores. Hereby can also lead to a central discharge of the condensate and blow-by steam the side of the first flange pin.
  • the roller according to the invention is thereby characterized in that the collecting space of the flange pin for deriving the Condensate and any blow-by steam through radial channels with one Collection space is connected in the center of the flange, which in turn is connected a double sealing head of the central bore is connected to the outside of the roll.
  • This radial division of the return transport of the condensate has the advantage that also the pressure difference from the peripheral holes to the central hole is divided. Pressure equalization takes place in the collection rooms. Of the Pressure difference from this point to the peripheral bores means there is a pressure drop opposite, which consists of a centrifugal component and a flow resistance put together. Is the centrifugal force component so large that it alone Corresponds to the pressure difference, a flow can no longer take place.
  • the Pressure difference is adjustable by the proposed design so that the Flow resistance with pure steam flow is greater than the maximum possible Centrifugal resistance, which occurs when the contents of the siphon is pure condensate, so no flow is possible. Stable drainage is so secured.
  • an open connection hole through a flange pin Connect the central bore of the roller to the environment.
  • a roller according to the invention can be designed so that for the return of the Condensate from the drive-side flange pin centrally in the inside of the roll arranged return pipe is provided.
  • this embodiment is like described in the introduction is very complex, sometimes there is Necessity of such a measure, which is then in an inventive Roller with little effort due to the absence of pressure in the interior of the roller is feasible.
  • roller described in FIGS. 1 and 2 is shown on the left in FIG. 1 Flange 8 driven. In such rollers is between the leader Pin 3 with a double sealing head for steam inlet and condensate drainage and to distinguish the drive-side pin 8.
  • connection channels for the steam are according to the invention as bores 4, 5, 6 housed in the driver-side pin 3.
  • the holes branch out according to the type of branch Tree.
  • the 48 peripheral bores of a roller with 1850 mm Outside diameter can be supplied with steam, which through the central bore 16 of the pin flows in, six of this central bore 16 initially run radial bores 6 obliquely inwards to the inner flange surface.
  • the flange is by means of cover plates 17th closed at these points.
  • cover plates 17th closed at these points At the ends of the now 12 blind holes of two peripheral holes inclined connecting holes 4 in Spigot flange introduced. This means that every second of the 48 peripheral holes is included Steam supplied.
  • connection of the adjacent holes, which are still without Steam supply are carried out in such a way that in the drive-side pin 8 through passages 7 a connection to the steam-carrying neighboring holes will be produced.
  • the amount of steam required in the holes connected in this way first flows as surplus steam through the neighboring hole and then from the drive side.
  • the amount of steam is in the ratio of the peripheral Bore cross sections so small that an adequate steam supply low steam speeds is possible.
  • the condensate - possibly together with a small percentage of blow-by steam - is from the steam pressure against the centrifugal force direction radially towards the middle of the roller annular collecting spaces 10 pressed at both roller ends.
  • these collecting spaces are distributed through a plurality of axially parallel bores 11 connected to each other in the roller body. This passes through these holes 11 Condensate from the drive side back to the driver side of the roller. Enough here then a few radial connecting pipes 12, also in the manner of siphons, to the condensate in a central condensate collector 13 in the middle of the driver's side To guide pin 13 and from there through the double sealing head again Roller out.
  • the interior 14 of the roller can be free of steam in the manner described and condensate are kept.
  • a direct open hole 15 from the inside of the roll this ensures through the pin flange to the outside.
  • the roller body can should not be viewed as a pressure vessel.
