Definitions

  • the invention relates to a floating dryer according to the preamble of Claim 1.
  • the amplitude of the sine wave depends, on the one hand, on the pressure that it generates Blown jet exerts flow on the web, on the other hand from the Tension that is effective in the web. If the web tension is too high, the The web is smoothed out so that the transverse stiffening is only weakly pronounced. In to low tensile stress, the wave crests grow, so that they the nozzle bars streak. The compressive forces depend on the speed and the amount of blown out air and the type of the nozzle bar.
  • the typical nozzle bar is about 50 to 100 mm wide, and the typical distance between adjacent nozzle bars (center to center) is mostly between 100 and 300 mm.
  • the typical tension is about 500 N per m web width.
  • the cause of the novel phenomenon was an elongation of the web in the transverse direction recognized. This is apparently caused by the fact that a larger amount is in the printing unit Water penetrates the paper as usual and causes the web to swell. Each after the throughput speed lies the point at which the maximum width is reached is already in the vicinity of the inlet slot or in a somewhat larger distance, which, however, is not greater even at the highest web speeds examined than about a third of the drying distance. After the maximum width is reached the web begins to shrink again due to drying.
  • the stretch in Transverse direction leads - in addition to the DE-Z specified in the introduction described effect - to an increased formation of longitudinal folds. Have this a height of about 8 mm and therefore touch the nozzle bars.
  • the weak trained cross shafts do not have a sufficient stiffening effect.
  • the Jet streams also have no significant spreading effect.
  • EP 0 192 169 B1 deals with the contact-free guidance of material webs in Cases where it is particularly difficult to distinguish between web stability and freedom from wrinkles on the one hand and high power density on the other hand to find a compromise.
  • the specified problem solution is that the areas in which the mouths the lower and upper nozzles are arranged, adapted to the desired waveform are traversed by the web. This device is especially for the Heat treatment of metal strips is provided.
  • Float dryers ensure good heat transfer with good stability of the web unite.
  • the nozzle bars which act as air cushion nozzles with two at a distance nozzle slots arranged from one another are larger than usual common.
  • the total width is approximately 13.35 cm. Even the distance between neighboring nozzle boxes is larger than usual: 30.48 to 38.1 cm.
  • the invention has for its object a floating dryer with the structural To create features according to the preamble of protection claim 1, in which freshly moistened sheets of swellable paper in the initial section of the Drying section can be guided without wrinkles without brushing the nozzle bars.
  • FIGS. 1 and 2 each show a very simplified embodiment of the invention.
  • FIG. 3 shows in perspective a preferred nozzle bar for a floating dryer according to the invention.
  • FIG. 1 shows, are in a housing 1 along a drying path, which by an inlet slot 2 extends to an outlet slot 3, horizontal nozzle bars 4a, 4b, 5a, 5b arranged, which symbolized themselves transversely to the arrow 6 Extend direction of passage.
  • the nozzle bars 4a, 5a form a lower row, the Nozzle bar 4b, 5b an upper row.
  • the nozzle bars 4a, 4b are in one Inlet gap 2 beginning section p of the drying section attached Nozzle bar 5a, 5b in the remaining section q.
  • the initial section p comprises approximately 10 to 35%, preferably about a third of the total drying distance.
  • the nozzle bars 4a, 4b accommodated in the initial section p have a uniform width b 4 .
  • the nozzle bars 5a, 5b also all have a uniform width b 5 , which is, however, significantly smaller than the width b 4 .
  • the ratio b 4 : b 5 is between 2: 1 and 3: 1.
  • the upper nozzle bars 4b are arranged offset to the lower nozzle bars 4a, so that a nozzle bar 4b preferably lies approximately centrally opposite a gap between two adjacent nozzle bars 4a.
  • the nozzle bars 5a, 5b are also arranged offset to one another
  • the nozzle bars 4a, 4b, 5a, 5b are designed as air cushion nozzles.
  • the nozzle bar 4a consists essentially of a hollow, enclosed by sheet metal box with a rectangular cross-section, which is provided on its top, adjacent to the side walls, with two blow slots 7, 8, which extend over the entire length of the nozzle bar 4a, ie in extend substantially over the working width of the levitation dryer.
  • a web plate 9 sits between the blow slots 7, 8.
  • the remaining nozzle bars 4b, 5a, 5b are designed accordingly, but the blow slots are provided on the underside of the upper nozzle boxes 4b, 5b.
  • the mouths of the blow slots of the lower nozzle bars 4a, 5a are located in a horizontal plane 11, the mouths of the blow slots of the upper nozzle bars 4b, 5b lie in a horizontal plane 12.
  • the distance d between the two planes is constant over the entire length of the dryer. Typical dimensions are given in the table below (in mm).
  • a 4 200-500 a 5 100-300 b 4 100-250 b 5 50-100 d 5 - 12
  • Each nozzle box 4a, 4b, 5a, 5b has, for example, an inlet opening for the drying medium on one end face. As is known, this is connected to a channel, not shown, which is connected to the pressure side of a fan, also not shown.
  • the dryer can also be constructed from a number of fields lined up with separate systems for circulating the drying medium.
  • a freshly printed paper web is fed to the floating dryer during operation In addition to the printing ink, the web also absorbed water in the printing unit.
  • a predetermined longitudinal stress of, for example Maintain 500 N / m.
  • the paper web is through the nozzle bars 4a, 4b, 5a, 5b Hot air applied to the entire drying section At the beginning, the forces exerted by the flow are relatively large.
  • the Paper web assumes a corrugated sheet-like shape in this area. This will make her in Braced transversely, so that the formation of longitudinal folds is suppressed.
  • section q the aerodynamic forces are significantly smaller.
  • the height of the waves is so low that the web is almost due to the longitudinal tension pulled smoothly. Bracing in the transverse direction is therefore only in correspondingly small.
  • section q is the per unit length supplied drying performance very high.
  • the paper web 13 is dried so far at the end of the initial section p that the broadening due to swelling exceeded or at least exceeded the maximum has reached. Therefore, there is an increased tendency to form longitudinal folds Section q no longer.
  • the formation of longitudinal folds is discussed in this section proven, state of the art nozzle arrangements and Operating parameters excluded.
  • the nozzle bars 14a, 14b, 15a, 15b a different cross-sectional shape than in FIG. 1.

  • the web plate 19 is perforated.
  • the Nozzle bar goes in a wedge-like manner on the side facing away from the web plate 19 narrowed channel connected to an air distribution box, not shown is
  • the width of the nozzle bars 14a, 14b is in several stages, preferably from nozzle bar to nozzle bar, reduced, as well as the distance between adjacent nozzle bars.
  • Nozzle bars 15a, 15b have the same width and are at equal intervals arranged
  • the invention does not require a specific shape of the nozzle bar. It is connected Can be used with all nozzle bars which are suitable for a staggered arrangement of upper and lower nozzle bars a continuous path in wave form stabilize aerodynamically in balance. Numerous suitable nozzles belong the state of the art.
  • a preferred nozzle bar 20 shown in FIG. 3 has a cross section similar to the nozzle bar shown in Figure 2, but differs from this in that the blow slots are replaced by rows of holes.
  • the holes are - as in DE 26 13 135 B2 described in detail, as semicircular recesses 21, 22 on the angled Edge strips 23, 24 of the side walls 25, 26 are formed.
