Definitions

  • the invention relates to a convection drying and / or fixing machine for the thermal treatment of a broadly guided textile fabric according to the preamble of claim 1.
  • a convection drying and / or fixing machine for the thermal treatment of a broadly guided textile fabric according to the preamble of claim 1.
  • Such a machine is known from DE-OS 27 54 438.
  • DE-PS 36 27 904 describes a convection drying and / or fixing machine which has at least one fan which is assigned to a common pressure chamber for the lower and upper 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 pressure chamber with a fan is provided below the lower nozzle box and above the upper nozzle box. In this way, the air systems of the lower and upper nozzle box can be completely separated from each other, but the overall height of the machine is increased, for example, compared to the case of the machine according to the aforementioned DE-PS 36 27 904 C2, at least by the vertical dimension of a fan.
  • DE-PS 9 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.
  • Each of these nozzle boxes has a fan directly at the nozzle box entrance assigned.
  • 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 box inlet means that either the pressure distribution within the connected nozzle box becomes uneven in the direction of transport of the goods (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.
  • DE-OS 27 54 438 describes a machine for drying thread sheets or coated carpets.
  • Two separate fans are provided for loading three superimposed web levels with corresponding pairs of nozzle boxes. Since the two middle nozzle boxes are geometrically both upper and lower nozzle boxes, the two fans must work in the same way (same temperature, same pressure).
  • the spatial structure of the machine with fans provided on both longitudinal sides of the machine is disadvantageous in practice, since access to the inside of the machine, where regular maintenance has to be carried out, is made correspondingly more difficult.
  • DE-OS 22 01 731 describes a tensioning machine whose heating and air delivery devices are integrated in a single radial fan.
  • the radial fan has a fan wheel with two flow spaces lying axially one behind the other with suction openings arranged coaxially to one another.
  • the impeller of the fan is divided so that it can suck in two air streams that flow through two concentrically arranged suction openings. With such an impeller alone, it is not possible to supply separately controlled air flows at different pressures to the lower and upper nozzle boxes.
  • the flow ratio is rather fixed in terms of design.
  • DE-PS 78 282 describes a drying machine with two fans located on a common axis.
  • the inflow and outflow spaces of the two fans are located side by side in the machine.
  • the fan for ventilation of the upper nozzle box is located in a different housing than the fan assigned to the lower nozzle box.
  • the two fans have a common drive shaft, a different speed setting and thus independent control of the air volume setting for upper and lower air is not possible in this case either.
  • 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.
  • two fans are thus arranged in separate pressure boxes in the space below the height of the lower nozzle box.
  • the two fans are approximately in the same range as in the case of DE-PS 36 27 904, but they are offset in the direction transverse to the direction of transport of the fabric to be treated so that each of the fans is one over the (in the Direction of pressure measured) over 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 inlet of the nozzle box.
  • one pressure box is cut off from the direct access to the return flow space by the other pressure box for reasons of geometry. To counter this problem.
  • a feedthrough is provided through the pressure box inlet part facing the return flow chamber 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 both 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 chamber is divided into separate rooms and the heat exchanger is divided into two partial heat exchangers.
  • 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 tensioning frame, is shown schematically.
  • the tensioning frame When the tensioning frame is operated, 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, in the direction perpendicular to the plane of the drawing, passed 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 for blowing out treatment gas in the direction of arrow 6 from above and below onto the fabric web 1.
  • the treatment gas is in each case with the help of two fans 7 and 8 in the direction of arrows 9 and 10 Nozzle boxes 4 and 5 upstream pressure box 11 and 12 promoted and ge reaches during normal operation of the machine through the pressure box outputs assigned to the nozzle box inlets 13 and 14 into the nozzle boxes 4 and 5.
  • 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 backflow 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 substantially 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 respectively.
  • the fan wheels 7, 8 offset in the direction of their axes one behind the other, and in Fig. 3 they are next to each other at the same height.
  • the two pressure box input parts 24, 25 extend at approximately the same height next to one another essentially over the entire nozzle box dimension 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, however, in order to achieve an even 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 also to be regulated separately, it is provided according to a further invention to divide the return flow space 19 into separate return flow partial spaces 28 for the upper pressure boxes 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.
