Definitions

  • the invention relates to a method for treating a material web according to the preamble of claim 1, and an apparatus for treating a material web according to the preamble of claim 8.
  • Such methods and the associated devices are used in particular in the textile industry for the broad treatment of fabric webs.
  • the fabric web is loaded with a treatment liquid in the treatment zone and then passes into a damper, where the desired process takes place.
  • fabrics made of cotton, linen or blends with synthetic fibers can be sized, boiled, bleached or dyed.
  • Treatment devices and methods have also become known in which the material web is stretched and guided through at least one U-shaped shaft which is filled with a treatment liquid. Examples of such systems are described in US-A-3,315,501 or in FR-A-2,037,438.
  • the supply of new treatment liquid always takes place above the liquor level, which is associated with a relatively strong foam formation.
  • this object is achieved with a method which has the features in claim 1.
  • the object is achieved with a device having the features in claim 8.
  • the flow velocity in the legs of the shaft relative to the material web can be set to a certain value in order to achieve a further treatment effect. This flow rate can even be changed with a circulation pump with adjustable delivery capacity.
  • the liquor level can be measured continuously and new treatment liquid can be added when the liquor level drops.
  • This supply takes place particularly advantageously in the connection area between the two legs of the shaft.
  • a turbulent flow forms there, with the tissue web being loaded intensively and with the entire depth of treatment liquid.
  • the treatment liquid can be in the legs of the shaft either in counterflow or in the direction of flow in cocurrent to the material web discharged at one end and fed back at the other end.
  • the counter-current operation causes a very intensive fleet exchange and a turbulent flow even in the legs of the shaft.
  • direct current operation supports tissue transport and thus a particularly gentle treatment in the treatment zone.
  • the concentration of the treatment liquid can be measured continuously, and if the concentration changes, either concentrate or thinner can be added. Since the difference in the degree of loading between the introduced and discharged material web can be determined beforehand and always remains approximately the same, an equal subset of concentrate and thinner, corresponding to the desired concentration, can also be added continuously. In this case, there is no need to measure the concentration. Together with the level regulation already mentioned, this ensures that the operating conditions in the treatment zone are always constant.
  • the concentration of the treatment agent is preferably measured in the connection area between the two legs of the U-shaped shaft. There is enough space available and due to the turbulent flow there, the treatment liquid is mixed thoroughly, so that representative values are always measured.
  • the walls of the U-shaped shaft are heated, and they can be designed as hollow walls through which a heating medium is passed.
  • the supply of the heating medium can be controlled via a temperature sensor in the shaft.
  • This heating device can also influence or regulate the temperature in the treatment zone in a particularly advantageous manner.
  • the temperature sensor is also arranged for the same reasons as the concentration sensor in the connection area between the two legs of the shaft.
  • the outer shaft walls are arranged to be displaceable or pivotable relative to the inner shaft walls.
  • the legs of the shaft can be widened, only the relatively small amount of liquid in the shaft having to be drained beforehand.
  • Figure 1 shows an impregnation compartment 1, which has a U-shaped shaft.
  • the shaft is formed overall by the left manhole leg 3, the right manhole leg 4 and by the connecting area 5, which connects the two manhole legs.
  • the upper ends of the two shaft legs 3 and 4 are provided with a conical extension 22.
  • the shaft stands on a frame 14 and has a width that is somewhat larger than the width of the material web 2 to be treated.
  • the material web 2 is introduced in the direction of arrow a via a guide roller 15 into the left shaft leg 3, deflected at a deflection roller 16 in the connection area and guided upwards again in the right shaft leg 4.
  • the material web is always stretched and does not touch the shaft walls.
  • the inner shaft walls 8 and 9 are fixedly arranged on the frame 14, while the outer shaft walls 6 and 7 can be moved or pivoted outwards.
  • the loader consists of a fixed lower roller 18 and a press roller 19.
  • the press roller can be pressed against the lower roller 18 with the aid of a pressure cylinder 20.
  • a compression spring 21 causes the pressure roller 19 to be completely relieved in the absence of internal pressure in the pressure cylinder 20. This arrangement enables the press roller to be placed only lightly on the material web, so that instead of being squeezed, only treatment liquid is stiffened. The squeezed or stripped treatment fluid flows back into the right shaft leg.
  • the level of the treatment liquid is continuously measured with a level measuring device 13 at the upper end of one shaft leg.
  • a control valve 11 in a feed line 10 for new treatment liquid can be activated via the level measuring device.
  • treatment liquid of the same nature can be supplied via this line.
  • only dilution liquid such as water can be added, for example, while the correct concentration of the treatment liquid is maintained in another way.
  • the feed line 10 opens into the spray pipes 12 and 12 ', which are arranged in the connection area 5 on both sides, and which preferably extend over the entire width of the shaft.
  • the treatment liquid can be injected under pressure from these spray tubes.
  • the upper and lower ends of these shaft legs are connected to a line network 25.
  • the connections are made crosswise, so that the upper end of the left manhole leg 3 and the lower end of the right manhole leg 4 and the lower end of the left manhole leg 3 and the upper end of the right manhole leg 4 are combined.
  • a circulation pump 26 is integrated in the line network 25, so that the treatment liquid in the shaft legs is set into a circular movement.
  • treatment liquid is drawn off from the discharge pipes 23 and pressed into the supply pipes 24. Obviously, this creates the opposite flow in the direction of the arrow b.
  • the circulation pump 26 is reversible, however, so that pumping can also be carried out in direct current to the fabric web 2.
  • the tubes 23 and 24 each open in pairs approximately opposite one another in the shaft.
  • a heating element 47 is integrated in the line network 25 and can be heated with a heating medium via the line 32.
  • a temperature sensor 35 measures the temperature in the shaft and controls the control valve 34. In this way, the treatment liquid can be heated or cooled.
  • the shaft is connected to a storage container 27 which contains treatment liquid of an increased concentration.
  • the connection is made via the line network 25.
  • the concentrate 29 can be fed into the line network via a feed pump 28 be fed.
  • a concentrate measuring device not shown here, has a concentrate measuring sensor 48, which is arranged in the connection area between the two shaft legs.
  • the feed pump 28 can be activated via this concentrate measuring device when the concentration drops.
  • the concentrate measuring device can also actuate the control valve 11, with diluent being supplied via the supply line 10.
  • the feed pump 28 and the control valve 11 can also continuously supply a predetermined partial amount of concentrate and water, corresponding to the amount of treatment liquid carried out when leaving the loading crimp 17.
  • the shaft walls 6 to 9 are only designed as simple plates, which may also be provided with stiffening elements.
  • a drain valve 30 is arranged on the floor.
  • FIG. 2 shows an alternative embodiment in which the shaft walls 6 to 9 are designed as hollow walls through which a heating medium such as e.g. Steam can be passed.
  • a heating medium such as e.g. Steam
  • the shaft walls preferably consist of welded profile tubes 31, square tubes having proven particularly useful. In this way, a particularly great stability of the shaft walls is achieved.
  • the profiled tubes are connected to one another at the grain boundary surfaces, preferably in such a way that a meandering flow takes place.
  • Steam is supplied, for example, via a feed line 32, which opens approximately in the lower region of the two shaft legs 3 and 4 in the cavity walls.
  • the movable outer walls 6 and 7 are connected to the fixed inner walls 8 and 9 via flexible lines, since the outer walls are movable.
  • the steam flows upwards in the hollow walls and is discharged again at a discharge line 33.
  • the fixed and sliding shaft walls are connected to each other via flexible cables.
  • a temperature sensor 35 is arranged in the shaft, which activates a control valve 34 in the feed line 32.
  • Figure 3 shows the device according to Figure 1 in the open state, i.e. with the outer walls 6 and 7 extended in the direction of the arrow c.
  • the displacement preferably takes place plane-parallel to the fixed inner walls 8 and 9, widening of the shaft legs 3 and 4 being achieved. This obviously makes it easier to pull in the material web and to clean the shaft.
  • the shaft was previously emptied via the drain valve 30.
  • the displacement or pivoting of the outer walls can be achieved by various means such as rails, lever mechanisms, etc.
  • FIG. 4 shows a partial cross section through a device according to the invention, the construction of the side wall being somewhat more clearly visible.
  • the two inner shaft walls 8 and 9 are firmly connected to side columns 36.
  • tie rods 37 are articulated on pivot pins 38 over the entire height at certain intervals.
  • the movable outer shaft walls 6 and 7 have lateral counterparts 40 with side slots 41.
  • the tension rods 37 have a thread on which a lever or a handwheel 39 is screwed. This allows the counterpart 40 to be clamped against the column 36 in the closed state.
  • the actual lateral sealing of the shaft leg takes place on a counterpart 46 against which a seal 43 is pressed. This seal sits in a sealing piece 42, which is by means of a clamping screw 44 is held adjustable on the counterpart 40.
  • the width of the shaft leg can also be adjusted in this way.
  • the extended state of the outer wall 6 is shown in the upper half of the figure.
  • the handwheel 39 on the tension rod 37 is released and the tension rod 37 is pivoted out of the slot 41 laterally.
  • the outer wall 6 can be extended, whereby it is guided by suitable means.
  • the tie rods 37 serve exclusively to apply the contact pressure.
