Definitions

  • the invention relates to a steam-heated hollow roller according to the preamble of claim 1.
  • Such a heatable with steam hollow roller is used for example in the production of corrugated cardboard as a so-called corrugating roll, as it is known from EP 0 917 949 B1 (corresponding US 6,092,579 ) is known. Furthermore, such steam-heated hollow rollers are used as so-called preheating rollers in corrugated cardboard plants to preheat paper webs. Further areas of application are in other fields of technology; Such hollow rollers are regularly used for heating or heating materials guided in webs over them.
  • steam usually saturated steam or superheated steam is blown into the inner hollow roll. It gives off its heat via the inner wall of the hollow roller to the jacket, wherein the water vapor condenses.
  • the condensate collects due to the gravity and the centrifugal force of the rotating hollow roller on the inner wall.
  • This condensate layer has an insulating effect and thus disturbs the heat transfer from the steam to the roller.
  • a siphon tube is used, the suction opening is located in the vicinity of the inner wall of the hollow roller.
  • the distance of the suction opening of the siphon tube from the inner wall of the hollow roller is crucial for the remaining amount of condensate in the interior space of the hollow roller.
  • the suction opening loop in, so that the siphon pipe rests tightly against the inner wall with the result that condensate can not be extracted.
  • the siphon tube consists of an outer, rigid support tube and a displaceably mounted therein, flexible insert tube, whereby the distance between the suction opening to the inner wall of the hollow roller is adjustable.
  • the distance between the suction opening to the inner wall of the hollow roller is adjustable.
  • the invention is therefore based on the object, a heatable with steam hollow roller of the generic type so that an exact adjustment of the distance between the suction opening and inner wall of the hollow roller is also possible during operation of the hollow roller.
  • the rotary feedthrough is adjusted by a predetermined angle, whereby exactly the height of the gap between the suction opening and inner wall is determined.
  • a corresponding display can be attached to the rotary passage.
  • the heatable hollow roller 1 shown in the drawing has a substantially cylindrical roller shell 2, which is closed vapor-tight by two end walls 3 and 4. At both end walls 3, 4 concentric with the central longitudinal axis 5 of the hollow roller 1 bearing pin 6, 7 are mounted, with rolling bearings 8, 9 in bearing blocks 10, 11th are stored. The hollow roller 1 is thus rotatably mounted. Such hollow rollers are rotatably drivable in the rule. Such a rotary drive, not shown in the drawing, can take place via the bearing journal 6 shown on the left in the drawing.
  • the bearing pin 7 shown on the right in the drawing is hollow. Through it, according to the flow direction arrow 12 from a water-steam source, not shown, water vapor introduced into the hollow roller 1, whereby the roller shell 2 is heated. By this heating process and the associated heat release of the steam condenses the water vapor. The condensate is sucked from the lower region of the inner space 13 of the hollow roller 1 by means of a so-called siphon tube 14, wherein the suction direction is indicated by the flow-direction arrow 15. To the siphon tube 14, a vacuum source, not shown, is connected.
  • This has a non-rotatable housing 17, which is arranged substantially concentric to the axis 5 and at its outer bottom 18, the siphon firmly connected to it Tube 14 carries.
  • a steam supply nozzle 19 opens.
  • the housing 17 of the rotary feedthrough 16 is rotatable by means of a spherical cap bearing 20 and pivotally connected to the bearing pin 7 relative to the axis 5.
  • the bearing 20 has a cylindrical inner wall 21, so that on the one hand, the siphon tube 14 is also free from the spherical cap bearing 20 and further between the siphon tube 14 and the housing 17 and the bearing pin 7 a ring channel 22 to Supplying the water vapor from the nozzle 19 in the inner space 13 of the hollow roller 1 is given.
  • the spherical cap bearing 20 may be made of a suitable plastic, so that it simultaneously abuts against the metal housing 17 on the one hand and the bearing pin 7 on the other hand, thus forming a vapor seal to the outside. Of course, however, other suitable seals may be provided.
  • the main longitudinal axis 23 of the siphon tube 14 extends in alignment with the central longitudinal axis 5 of the hollow roller 1.
  • the inner lower suction opening 24 has a minimum distance a to Inner wall 25 of the hollow roller 1.
  • This angle ⁇ can be up to 5 °. In general, the angle will be ⁇ ⁇ 2 °.
  • a manually operated pivoting adjustment device for the siphon tube 14 results from the Figures 3 and 4 ,
  • the hollow bearing pin 7 bearing block 11 In stored on the hollow bearing pin 7 bearing block 11 are in a horizontal plane in which the central longitudinal axis 5 is located on both sides of the bearing pin 7 and the housing 17 bearing rods 26, 27 screwed.
  • the housing 17 of the rotary bushing 16 On these bearing rods 26, 27, the housing 17 of the rotary bushing 16 is pivotally mounted by means of spherical pivot bearing 28 so that the previously with respect to the FIGS. 1 and 2 described pivoting movements can be performed.
  • the two spherical pivot bearing 28 have a common horizontal pivot axis 29, which is aligned with the central pivot axis 30 of the ball dome bearing 20.
  • the pivoting adjustment and -Fest ein the rotary passage 16 with siphon tube 14 is carried out in the embodiment of the FIGS. 1 to 4 by means of two pairs of adjusting screws 31, 32 which are mounted in corresponding laterally projecting abutments 33, 34 and abut against the bearing rods 26 and 27, respectively.
  • the housing 17 of the rotary passage 16 from the in FIG. 1 position shown in the in FIG. 2 pivoted position shown and fixed there each. A backup of this position via counter-nuts 35th
  • a linear drive 36 is provided in the form of a hydraulically or pneumatically actuated piston-cylinder drive, wherein the one lower end of the cylinder 37 is pivotally hinged to a stationary bearing 38, while the piston rod 39 is hinged in the lower region of the housing 17 by means of a bearing 40.
  • the piston rod 39 is adjusted relative to the cylinder 37, which in turn the housing 17 of the rotary feedthrough 16 is adjusted in the manner described.
  • hydraulic locking simultaneously fixing the housing 17 in this desired position.
  • the embodiment according to the FIGS. 6 to 9 is different from the one after the FIGS. 1 to 4 in that not only the gap 41 between the suction opening 24 of the siphon tube 14 and the inner wall 25 of the hollow roller 1 can be adjusted, but that the siphon tube 14 by means of a rotary-adjusting device to its main longitudinal axis 23 can be pivoted, so that the opening 24 is not located in the vertical longitudinal center plane 42 of the hollow roller 1, as in the embodiment of the FIGS. 1 to 4 or in the position according to FIG. 8 but in a thereto by a rotational angle ⁇ inclined longitudinal center plane 43 according to FIG. 9 , To make this possible, a ring bearing 44 is formed on the bearing block 11 ', on which a ring disc 45 is rotatably mounted.
  • the ring disc 45 is - like the FIGS. 6 . 8 and 9 can be seen - held by two arranged in the vertical longitudinal center plane 42 screws 46 on the bearing block 11 '.
  • the screws 46 pass through in the circumferential direction of the ring disc 45 extending longitudinal holes 47, so that - corresponding to the length of the long holes 47 - the ring disc 45 can be adjusted by the angle ⁇ in the circumferential direction, the angle between the Levels 42 and 43 corresponds.
  • the bearing rods 26 "and 27" are attached to the ring disc 45 in this case. Otherwise the construction is like to FIGS. 1 to 4 described.
  • the housing 17 of the rotary leadthrough 16 can be pivoted with the siphon tube 14 about its main longitudinal axis 23, so that the opening 24 is adjusted in the direction of rotation 48 of the hollow roller 1 can be.
  • the mentioned condensate taken in the direction of rotation 48 becomes.
  • An adjustment of the distance b of the suction opening 24 from the inner wall 25 of the hollow roller 1, that is, an adjustment of the width of the gap 41, also takes place here via the two pairs of adjusting screws 31,32.
