Definitions

  • the invention relates to a device for conditioning, cleaning, and / or keeping a rotating roller and / or a rotating roller clean Tape of a paper machine.
  • a device for conditioning, cleaning, and / or keeping a rotating roller and / or a rotating roller clean Tape of a paper machine is for example described in DE-A-198 10 800.
  • the aim of the invention is to provide an improved device of the type mentioned To create a way that eliminates the aforementioned drawbacks and the cleanliness of the rotating roller is maintained.
  • This object is achieved according to the invention in that the rotating Roller or the rotating belt at least two in roller or Tape running direction arranged one behind the other, a distance from each other having scrapers are assigned.
  • a respective scraper hydrodynamically creates a vacuum generated.
  • the corresponding hydrodynamic effects occur in particular in that the respective scraper is set at an angle. While the scraper is in the front in the direction of the roll or strip, water from the at least substantially open, i.e. especially grooved and / or peels off the drilled roller or belt surface air scraped off by the rear scraper. Thereby the air intake is corresponding in a subsequent gusset minimized.
  • a corresponding gusset can, for example result in that the scraper in the direction of the roll or belt are arranged at a point where at least one felt on the roller or the tape runs up.
  • a low-pressure suction is provided for suction of the gusset, at least by the rotating Roll, the felt running onto this, in the direction of the roll or belt looks at the rear scraper and the one provided on the felt Border layer scraper is formed.
  • the distance between the boundary layer scraper and the felt contact point is expediently less than 500 mm, in particular less than 400 mm and preferably less than about 300 mm.
  • the scrapers are assigned to a suction felt guide roller. This can be done especially afterwards be provided to the first press of the press section of the paper machine.
  • This first press of the press section can be, for example a roller press, but also a wide nip and shoe press.
  • Device is in the direction of the roll or tape between the Scraper at least one that acts on the roller or belt surface Cleaning device provided.
  • At least one can Blast cleaning or spraying device can be provided to the roller or to apply a pressure medium to the belt surface.
  • pressure medium in question can be, for example, a liquid, in particular water, or air.
  • the cleaning device a combined blowing or spraying and suction device includes.
  • the cleaning device comprises at least one transverse to the direction of the roll or strip traversing and rotating around its axis spray head to the To apply pressure medium to the roller or belt surface. This results in a high cleaning effect with minimal pressure medium consumption achieved.
  • the medium acting on the surface of the roll or strip is stationary advantageously under a pressure greater than about 20 bar and preferably is less than 25 to 30 bar.
  • the spray head preferably comprises at least one inclined to its axis Jet.
  • the spray head can be, for example, a vapor extraction device be assigned.
  • the cleaning device is expediently encapsulated or by enclosed in a housing open to the roll or strip surface.
  • the encapsulation or the housing can face each other via the scraper the roller or belt surface to be sealed.
  • the device according to the invention are means for equalization in a grooved and / or blind drilled roll or belt surface to a press nip conveyed amount of water.
  • the equalizing or water removing means preferably comprise Means for blowing out the grooves and / or blind holes with a pressure medium, especially compressed air.
  • the equalizing or water removing agents can be one Include suction device to remove water from the roll or belt surface suck.
  • a combined one Blower and suction device provided.
  • the equalizing or water removing means preferably comprise a device to a on the roll or belt surface create hydrodynamically generated negative pressure. You can do this Vacuum generating means in particular at least one inclined Scraper, preferably include at least one foil scraper.
  • Figures 1 to 3 show different embodiments of a device 10 for conditioning, cleaning and / or keeping one clean rotating roller 12 or 14 of the press section of a paper machine.
  • the respective rotating roller 12 and 14 are two in each case Roller running direction L arranged one behind the other, a distance from each other having scraper 16, 18 assigned, which as a foil scraper are trained.
  • this first Press 20 in the present case is a roller press.
  • she can also be formed by an extended nip press.
  • the scrapers 16, 18 are in the direction of the barrel L arranged in front of a point 22, at least one Felt 24 runs onto the felt suction roll 12.
  • the scraper 16 can in particular be a water squeegee act. It can be pressed against the roller. With the scraper 18 can be, in particular, an air scraper.
  • the rear scraper 18 viewed in the direction of roll L is with a in front of the felt runner 22 arranged on the felt 24 provided boundary layer scrapers 26 connected.
  • the distance a between the interface scraper 26 and the felt run-up point 22 is advantageously less than about 500 mm, in particular less than about 400 mm and preferably less than about 300 mm.
  • suction 78 for suction of the room provided between the press 20 and the rotating roller 12. This can be provided, for example, for suction of the entire space mentioned his.
  • the lower roller 28 of the press 20 are two water squeegees 32 assigned. Basically, such strips can be simple or be provided twice.
  • the device 10 of the lower counter roll 14 with an upper shoe press unit here assigned to an upper shoe press roller 46, provided shoe press 48.
  • the two scrapers 16, 18 are at a distance from one another on the outer circumference the grooved and / or blind drilled counter roll 14 is arranged.
  • Cleaning device 50 acting on the roller surface is provided in the direction of roll L between the two scrapers 16, 18 .
  • a jet cleaning or spraying device be provided to the roller surface with a printing medium apply.
  • a liquid for example, in particular water or air can be provided.
  • the cleaning device 50 comprises at least one traversing transverse to the direction of roll L about its axis 52 (see also FIG. 3) rotating spray head 54 around the roll surface to be loaded with the respective pressure medium.
  • This can the medium acting on the roller surface, for example, under a Stand pressure that is greater than about 20 bar and preferably less than 25 up to 30 bar.
  • the spray head 54 comprises at least one, in the present case at least two nozzles 56 inclined to its axis 52 the nozzle jets 58 are inclined with respect to the axis 52 (cf. FIG. 3). At in in in the direction of arrow F rotating spray head 54 hit the nozzle jets 58 thus alternately on the grooved and / or blind drilled roll surface 60.
  • the front scraper 18 in the direction of roll L empties the grooves 62 and Blind bores of the roller surface 60, whereupon the nozzle jets 58 are used more effectively.
  • the spray head 54 can have a vapor extraction device 64 can be assigned.
  • the cleaning device can 50 encapsulated or from a housing open to the roller surface 60 66 be enclosed. This housing 66 is over the scraper 16, 18 sealed against the roller surface 60.
  • the L rear wall 68 of the housing 66 for example by a rubber blanket be educated.
