Definitions
- the invention relates to a method for washing a textile web according to the preamble of claim 1 and a wide-width washing machine according to the preamble of claim 2.
- REPLACEMENT LEAF Arranged in which the liquid which has passed through the material web and is loaded with the washed-out residues is collected without pressure and pumped back into the rinsing unit.
- the invention has for its object to achieve an improved washing effect in a generic method and such a wide-washing machine.
- An essential point of the present invention is that steam is injected into the web on one side and is drawn off in the vicinity of the injection area on the other side, together with the residues remaining in the web, under the effect of a strong negative pressure. It has been shown that only the blowing up of the steam under a clear overpressure with practically simultaneous suction from the other side under a vacuum of at least 0.2 bar results in a substantial increase in the washing effect.
- the negative pressure should therefore not only suffice to achieve a mere removal of the medium that has passed through the web, but should result in a strong flow through the web, so that the residues just hit by the inflated steam are, as it were, torn out of the web in this state .
- REPLACEMENT LEAF leave slightly increased moisture so that the heat content of the web remains essentially unchanged and in any case not much heat is transported out of the process in this way.
- the expression "in the neighborhood" for the mutual position of the outlet opening and the inlet opening is intended to mean that the application of the steam on one side of the web and the suction from the other side are not at a greater distance from one another in the conveying direction and one corresponding time interval, but in one go. Even if it is not imperative that the outlet opening and the inlet opening lie exactly opposite one another, and also not that both with their limitations lie against the web under pressure (although this is the preferred embodiment), the distances that occur should be of the openings or their boundaries in the conveying direction of the web and perpendicular to the web surface are of the order of magnitude of the openings in the conveying direction, that is to say in practice they are in the order of millimeters or at most a few centimeters. This close “neighborhood” makes it possible to maintain the pressures required on the pressure side and the suction side to achieve the washing effect, without having to use excessively dimensioned pressure and suction pumps.
- the residues consist of organic treatment agents or auxiliaries or comprise agents which have considerable molecular sizes.
- the idea is that these large molecules are stimulated by the energy supply until they are broken down or split up and removed by suction in the "neighborhood" in this more mobile state before they can come together again to form larger and less mobile units.
- REPLACEMENT LEAF Pressure and suction devices arranged directly opposite each other on both sides of the web are known per se from DE 31 03 359 C 2, but the medium moved through the web here is not steam, but foam, and it is also not about the Wa ⁇ rule, but on the contrary to apply a treatment agent to the web.
- Claims 4 to 11 show various configurations of the outlet or inlet opening which are possible within the scope of the invention.
- An important feature is the adjustability of the openings according to claim 12, because this enables adaptation to different goods.
- the formation and arrangement of the openings e.g. in the case of loose thin goods, in the case of tightly knocked solid goods, in the case of pile goods and even in the case of carpets, it must be different.
- the adjustability is particularly advantageous in cooperation with a control and regulating device according to claim 13, which allows the washing process to be regulated as a function of goods-specific parameters, that is to say to design it automatically.
- the control and regulating device can comprise several controllers assigned to the individual components of the machine; however, it is preferred to combine the essential or all of the control and regulating elements in a central control and regulating unit (claim 15).
- this can relate in particular to the flow quantity and / or the flow pressure and what the extent of the openings in the conveying direction, ie the width relates to the slot nozzles, in the manner reproduced in claim 16.
- a special control variable, which is characteristic of the washing effectiveness, is the concentration of the residues washed out of the material web in the extracted medium. This can be included in the regulation according to claim 18.
- the concentration of the residues remaining on the material web can also be determined and the corresponding concentration value can be used for regulation (claim 19).
- a gas in addition to the steam e.g. Air and / or a liquid, e.g. Injecting water into the web and sucking it back together with the steam on the other side (claim 20).
- FIG. 4 shows a circuit diagram of a special embodiment of a wide-range washing machine according to the invention.
- a textile web 1 is indicated, which is horizontally conveyed in the spread position and has a certain permeability, so that steam inflated onto the web 1 can pass through the web 1.
- an injection device 10 is provided above the web 1 with an outlet opening 10 ′ running across the width of the web, that is perpendicular to the plane of the drawing.
- the outlet opening 10 ' is delimited by a slot nozzle 40, the Expansion in the conveying direction 1 'of the web 1, ie the slot width 41 is adjustable.
- a possible range for the slot width 41 is approximately 1 to 2 mm.
- a suction device 20 with an inlet opening 20 ' is provided below the web 1, which is formed by a slot nozzle 50 with an adjustable slot width 51.
- the expansion of the outlet openings in the slot nozzles 40, 50 in the width direction of the web is adaptable to the width of the web 1, so that there is no loss of steam or suction power.
- the slot widths 41 and 51 are the same and the slot nozzles 40, 50 lie exactly opposite one another.
- the outlet edges of the slot nozzles 40, 50 bear against the web 1 under slight pressure from both sides.
- steam is generated under an overpressure of at least 0.2 bar, better still somewhat higher, e.g. in the range of 0.5 bar on the top of the web 1 and blown into it, which is indicated by the arrow I.
- the medium passed through the web 1 i.e. a mixture of steam, water and the residues released from the material web 1 is suctioned off with a vacuum of at least 0.2 bar, better still 0.5 bar, which is symbolized by the arrow A.
- the slot nozzle 40 corresponds to that according to FIG. 1.
- the web 1 lies against the nozzle edges.
- the slit nozzle 50 'of the suction device 20 has a width 51' which is approximately twice as large as the slit nozzle 40 and, with its trailing limitation, is offset by a distance 52 'in the conveying direction 1'.
- the distance 52 ' is smaller than the width 41 of the slot nozzle 40, so that the slot nozzle 50' in the region 54 'is still partially below the slot nozzle 40, but extends beyond it in the conveying direction 1
- REPLACEMENT LEAF stretches so that in region 53, in addition to the steam remaining in the web, the condensate formed there and the residues to be removed, air is sucked through the web 1 from the outside. In the area 52 'there is no nozzle opposite the outlet opening 10', but the amount of steam which exits through the web 1 into the outside space is relatively small, since in particular in the first phase the inflated steam immediately blows up and in The web of material condenses and remains largely in the slot nozzle 50 'until it is reached.
- the slit nozzle 50 "of the suction device 20 is approximately three times as wide as the slit nozzle 40 of the injection device 10 and is offset with respect to it with its trailing edge by a distance 52" in the conveying direction 1 ', which is larger than the width 41 of the slot 40. It is thus no overlap of the slit nozzles 40 and 50 'more' before.
- the embodiment of Fig. 3 differs from the two previous embodiments in that the edges of the slot nozzle 41 are located slightly above the web, i.e. maintain a certain distance from the web 1 perpendicular to its surface. Part of the steam blown in the direction of arrow I will therefore flow laterally parallel to the web and partially condense on it or, insofar as it passes through the slot nozzle 50 ", from the negative pressure prevailing there in the direction of arrow A into the web 1 - and are torn through them. However, the web 1 will always rest on the edges of the slit nozzles 50, 50 ', 50 ", since it is sucked in by the negative pressure prevailing there.
- outlet opening 10 'and the inlet opening 20' should always remain in the vicinity of one another, which should mean that the two should not be apart from one another by more than the order of magnitude of a slot nozzle width. Both the transfer amounts 54 'and 54 "as well
- the distance amount 42 should therefore only be a few millimeters or centimeters. It is therefore not intended to inject the steam in the direction of arrow I at one point and to suction in the direction of arrow A at a point, for example, one meter behind it. Rather, the steam should be applied and injected into the web 1 and immediately or practically immediately sucked off again.
- FIG. 4 corresponds to the embodiment and arrangement of outlet opening 10 'and inlet opening 20' of the embodiment according to FIG. 1.
- the web 1 is guided over guide rollers 2 to 5, of which at least the guide roller 5 is driven by a drive motor 6 , drawn between the Injetechnischseinric device 10 and the suction device 20.
- the injection device 10 and the suction device 20 have an injection slot nozzle 11 and a suction slot nozzle 21, which are pressed against one another by means of pressing devices 12 and 22 with the web 1 being interposed.
- the interior of the injection device 10 is connected to the interior of the suction device 20 only separated by the web 1.
- the inner spaces are essentially sealed off from the outside.
- the injection slot nozzle 11 and the suction slot nozzle 21 each have an adjusting slide 13 or 23, which can be adjusted via an adjusting motor 14 or 24.
- the setting is carried out in such a way that the expansion of the slot nozzles 11, 21 in the conveying direction 1 ', that is to say the length L, over which the web 1 is clamped between the edges of the slot nozzles 11 and 21, can be adjusted and adapted if necessary.
- the length of the slot nozzles 11, 21, that is to say their extension perpendicular to the conveying direction 1 'of the web 1 (ie perpendicular to the plane of the drawing), is adapted to the width of the web 1. You can do this using the slot
- SPARE BLADE comprise nozzles 11, 21 which are telescopically inserted into one another and displaceable against one another.
- the interior of the suction device 20 is connected to the suction side of a suction pump 25, which sucks the mixture which has passed through the goods train 1, compresses it and supplies it to a heat exchanger / condenser 26.
- the condensate coming cooled from the heat exchanger 26 with the residual substances contained therein and removed from the web 1 is fed from a condensate pump 27 to a washing medium inlet line 33 via a valve 28.
- the flow quantity of the washing medium in the inlet line 33 is sensed by a flow sensor 32, the output signal of which is fed to a control device 7.
- the pressure-side outlet of the condensate pump 27 is connected via a test flow valve 29 to a test device 30, which generates output signals which reflect the contamination state of the concentrate or its concentration of residual substances taken up.
- the condensate examined is fed back into the inlet line, but can also be discarded since the amount of liquid still required for the examination is small.
- the feedback valve 28 and the test flow valve 29 are controlled by the central control and regulating unit 7.
- the inlet line 33 is connected to a fresh water supply via a fresh water valve 31 controlled by the central control and regulating unit 7 and leads through the heat exchanger 26, so that returned condensate mixed with fresh water can be heated in the heat exchanger 26.
- the preheated liquid coming from the heat exchanger 26 is fed to a steam generator 19 which can be heated by means of a heater 18 controlled by the central control and regulating unit 7.
- a water pipe 9 is provided, via which waste water
- REPLACEMENT LEAF can be discharged from the steam generator 19 via a valve 17 controlled by the central control and regulating unit 7. This makes it possible to evaporate the recirculated condensate in the steam generator 19 and to keep it in the steam generator 19 at a consistently high concentration of residues, so that the discharged amounts of waste water are small or the residues removed from the web 1 in the Waste water in high concentration.
- the steam generator 19 delivers steam to the injection device 10 via a steam control valve 16 controlled by the central control and regulating unit 7.
- a pump 8 controlled by the central control and regulating unit 7 is provided in order to directly return the condensate bypassing the steam generator 19 to add to the steam behind the valve. If necessary, another washing liquid or fresh water can also be added here. In this way, the steam can be influenced in its degree of saturation.
- the admixture is again regulated by the central control and regulating unit 7.
- a gas, in particular air is provided for the steam. This is particularly advantageous if, owing to the given conditions on the web 1, large flow quantities per unit of time are necessary.
- the central control and regulating unit 7 works here in such a way that the entire washing process corresponds to goods-specific data that can be input via an input device 34 and treatment-specific data such as e.g. the conveyor speed is regulated and controlled.
- the washing process is monitored in accordance with the output signals of the test device 30 via a display device 35.
- the higher-level control loop also includes the test device 30.
- REPLACEMENT LEAF Not only the steam throughput, but also the length L of the "treatment section” and optionally (in the case of embodiments according to FIGS. 2 and 3) the lengths of the offset sections 54 ', 54 "can be set in this way via the central control and regulating unit 7 An important point is that the washing effect is brought about by the action of the steam without the application of additional chemicals.
- the concentration of the residues remaining on the web 1 after suction can also be determined in a residual chemical measuring device 36 which is arranged in the conveying direction 1 'behind the suction device 20 and in 4 is indicated by dash-dotted lines.
- the measurement signal is fed to the central control and regulating unit 7 via the signal line 37 and used for regulation.
- Width 41 of the injection slot nozzle 40 1mm
