Definitions

  • the invention relates to a convection drying and / or -fixing machine for the thermal treatment of a web of textile material which is guided transversely to the direction of transport with a treatment gas, which is connected to a fan and which extends above and below the web of material and across the width of the nozzle boxes and one in Flow direction of the treatment gas on each nozzle box following return flow space for circulation of the treatment gas via heat exchangers, fans and nozzle boxes, wherein each of the two fans is mounted in a separate pressure box leading directly to the inlet of the associated nozzle box.
  • a separate or independent pressure setting on the upper and lower nozzle box can be achieved if, according to DE-OS 29 08 348, a separate pressure box with fan is assigned to each nozzle box.
  • a separate pressure box with fan is assigned to each nozzle box.
  • it is provided to provide a pressure chamber with a fan below the lower nozzle box and above the upper nozzle box.
  • the air systems of the lower and upper nozzle boxes can be separated from each other, but the overall height of the machine is increased, for example, compared to the case of machines according to the German patent mentioned at the beginning, by at least the vertical dimension of a fan.
  • Another DE-PS 29 27 974 describes a device for the continuous shrinking treatment of textile webs, in which nozzle boxes are also provided above and below the textile web, from which the textile web is to be blown simultaneously with a treatment gas from above and below.
  • a fan is assigned to each of these nozzle boxes directly at the nozzle box entrance.
  • the two fans are one above the other and can be driven by a single motor via a common shaft. This allows the overall height of the entire machine to be reduced, but the arrangement of the fans directly at the nozzle inlet means that either the pressure distribution within the connected nozzle box in the direction of transport of the goods becomes uneven (which would not interfere with the tumbler application according to this patent specification ), or fans with fans must be provided in close succession along the length of the machine with a correspondingly high effort.
  • the invention has for its object to design the above-mentioned machine so that an independent control of the pressure, in particular also the temperature, in the lower and upper nozzle box is possible with substantially unchanged overall height and without loss of performance.
  • the solution according to the invention for the above-mentioned convection drying and / or fixing machine, in which each of the two fans is mounted in a separate, directly - and essentially only - pressure inlet leading to the inlet of one of the nozzle boxes, is that the two Fans are arranged at substantially the same height above the floor below the level of the lower nozzle box within the inlet parts of the associated pressure boxes, that the two pressure box inlet parts extend next to one another at approximately the same height, essentially over the entire nozzle box extension measured in the transport direction, and that the fan of the pressure box inlet section cut off from the backflow chamber has an intake pipe leading through the other pressure box inlet section to the backflow chamber.
  • two fans are thus arranged in separate pressure boxes in the space below the height of the lower nozzle box.
  • the two fans are roughly in the same range as in the case of DE-PS 36 27 904, but they are offset from one another in the direction transverse to the transport direction of the fabric web to be treated, so that each of the fans can move about the (in the Direction of pressure measured) the entire length of the nozzle box can lead from the fan to the nozzle box.
  • Such a pressure box ensures an even pressure distribution at the nozzle box inlet.
  • the one pressure box is cut off from the direct access to the return flow space by the other pressure box for reasons of geometry.
  • a passage through the pressure box inlet part facing the return flow space is provided according to the invention and is designed as an intake pipe of the fan mounted in the other pressure box inlet part. Since each of the fans does not require more volume for the air delivery than previously for supplying the two nozzle boxes together, no more space is required for the pressure boxes in the direction transverse to the transport direction than according to the prior art.
  • both nozzle boxes have a common return flow space and a common heating via heat exchangers, a separate temperature setting on the top and bottom of the fabric web to be treated cannot be easily achieved.
  • the backflow spaces of the upper and lower nozzle boxes are separated from one another and have separate connections, each with a heat exchanger, to the pressure box inlets.
  • the return gas coming from the lower and upper nozzle box is conducted in separate ways via separate heat exchangers to the area below the lower nozzle box and is fed there to the two fans via separate channels.
  • a vertical section perpendicular to the longitudinal direction of the machine which is designed in the embodiment as a so-called clamping frame, is shown schematically.
  • the fabric web 1 to be treated is held in chains 2 and 3 at its longitudinal edges in the transport direction of the fabric web, that is to say in the direction perpendicular to the plane of the drawing, between two nozzle boxes 4 and 5.
  • One nozzle box namely the upper nozzle box 4
  • the other nozzle box namely the lower nozzle box 5
  • the nozzle boxes 4 and 5 have (not shown) hole or slot nozzles Blowing out treatment gas in the direction of arrow 6 from above and below onto the fabric web 1.
  • the treatment gas is conveyed by means of two fans 7 and 8 in the direction of arrows 9 and 10 into a pressure box 11 and 12 upstream of the nozzle boxes 4 and 5 and reaches the normal operation of the Machine into the nozzle boxes 4 and 5 through the pressure box outputs assigned to the nozzle box inlets 13 and 14.
  • the fans 7 and 8 should have independently controllable motors 15 and 16. From there, the treatment gas flows in the direction of the arrow 6 onto the fabric web 1 and from it essentially in the direction of the arrow 17 and 18 into the return flow space of the machine, generally designated 19, and from there via a heat exchanger or the like, generally designated 20 in the direction of the arrow 21 and 22 the suction side of the respective fan 7 or 8 supplied.
  • the two fans 7 and 8 according to FIGS. 1 to 3 are arranged essentially at the same height above the floor 23 below the level of the lower nozzle box 5 within the inlet parts 24 and 25 of the pressure boxes 11 and 12. 1, the fan wheels 7, 8 are offset one behind the other in the direction of their axes, and in FIG. 3 they are adjacent to one another at the same height.
  • the two pressure box inlet parts 24, 25 extend at approximately the same height next to one another essentially over the entire nozzle box extension measured in the transport direction 26 (FIG. 2) of the fabric web 1. In this way, the front pressure box input part 24 cuts off the rear pressure box input part 25 from the backflow space 19 itself.
  • the formation of the print box input parts 24 and 25 and the print boxes 11 and 12 over the entire length of the print box extending in the transport direction 26 is important in order to achieve a uniform pressure distribution over the length of the print box at the print box exit or at the print box input 13 and 14.
  • These contradicting conditions are solved according to the invention in the following way: through a passage through the pressure chamber 24 designed as a suction pipe 27 (FIG. 2), the treatment medium (including air) flows from the backflow chamber 19 to the fan 8 of the rear pressure box inlet part 25.
  • a suction pipe 27 interferes the air flow within the front pressure box inlet part 24 is not, so that a pressure distribution can be achieved in both nozzle boxes 4 and 5, which can be individually varied in any manner and is uniformly adjustable over the entire pressure box area.
  • the temperature in the upper and lower pressure boxes 4, 5 is to be regulated separately, according to another Invention provided to divide the backflow chamber 19 into separate backflow subspaces 28 for the upper pressure box 4 and 29 for the lower pressure box 5.
  • the heat exchanger 20 is divided into two partial heat exchangers 30 and 31 for the backflow partial spaces 28 and 29.
