Definitions

  • An apparatus for treating fluid-permeable materials which includes a treatment chamber adapted to contain a gaseous or liquid treatment medium, inlet means for introducing the material to be treated to the treatment chamber, at least one perforated roller-like conveying means rotatably disposed within said treatment chamber, the conveying surface of said rollerlike conveying means being provided by an outer perforated jacket means, an inner perforated jacket means spaced closely adjacent to the outer jacket means, the inner and outer jacket means cooperating to allow treatment of material of substantially differing widths without appreciably affecting the rate of flow of the treatment medium across the conveying surface, means for rotating the conveying means, means for circulating the treatment medium from the outside to the inside of the conveying means, thereby penetrating the material being conveyed thereon, and outlet means for removing the material from the treatment chamber.
  • the present invention relates to an apparatus for treating fluid-permeable goods, especially textile goods, in a container or a housing containing at least one sieve drum' means and at least one unit which serves for circulating a treatment medium, e. g. a liquid, or steam-like and/or gaseous processing medium.
  • a treatment medium e. g. a liquid, or steam-like and/or gaseous processing medium.
  • the sieve drum is penetrated by the treatment medium, preferably from the outside to the inside thereof.
  • a baffle plate is installed in the sieve drum which prevents the processing medium from entering the drum at that portion which is not covered by the material being treated.
  • the application of the covering means as necessitated by the prior art'produces prolonged down-times. With aggressive processing liquors it may even be necessary to drain these liquors from the bowls containing the drums before the covers can be applied in order to protect the operators against the highly concentrated caustic solutions or boiling liquors.
  • An object of the present invention is to avoid the prior art disadvantages in the treatment of textile materials.
  • Another object of the present invention is to provide an improved apparatus which makes a perforated drum or sieve drum means adaptable to treating textile materials with varying material widths.
  • the free space (i.e. the perforated area through which the processing medium flows) of the inner sieve drum jacket is smaller than that of the outer jacket so that a sufficiently large resistance to the inflowing processing medium is provided.
  • the holes or perforations of the inner drum jacket arelarger than those of the outer jacket so that there is no danger of fibers that have entered the clearance through the holes of the outer jacket from clinging to the inner drum jacket.
  • the inner sieve drum jacket need not be very strong and can therefore be substantially thinner than the outer jacket. This is especially important since the sieve drums are generally made of high-quality steels.
  • FIG. 1 is a cross section of a sieve drum bowl
  • FIG. 2 is a longitudinal section of the bowl according to FIG. l;
  • ' v I FIG. 3 is an enlarged section of the sieve drum jackets with liquor level and pressure curves denoting the pressure drops or resistances to flow created across the jackets;
  • FIG. 4 is a cross section ofa sieve drum device which serves for drying, steaming and/or heat-setting
  • FIG. 5 is a longitudinal section of the device according to FIG. 4.
  • the apparatus according to FIGS. 1 and 2 consists of a liquor container 1 in which a sieve drum 2 is accommodated.
  • the sieve drum 2 is provided with an outer perforated sieve drum jacket 3 and an inner perforated sieve drum jacket 4.
  • a textile material length 6 is guided around a substantial portion of the sieve drum surface provided by the outer jacket; the textile material only covers a section of the width of the outer jacket.
  • rollers 8 Associated with the sieve drum are rollers 8 which ensure the further conveyance of the textile material length 6. Using these rollers, the textile material length is transported to a subsequent squeezing unit 7.
  • an exhaust device can be provided for dehydrating the material.
  • the liquor level 9 outside the sieve drum 2 is substantially higher than the liquor level 9 inside the sieve drum.
  • the textile material length 6 is penetrated by the processing liquor because of this liquor level difference.
  • a lateral collecting vessel 10 is installed at one front side of the sieve drum 2 .
  • the liquor from within the sieve drum flows into this vessel.
  • the liquor is then pumped back into the bowl section outside the sieve drum by means of a pump 11.
  • a pump motor 12 with a flange-mounted variable speed gear 13 is supported above the collecting vessel 10. The pumping capacity can be adjusted via the variable speed gear by turning a hand wheel 14.
  • the damming effect of the inner drum jacket 4 prevents the amount of liquor which flows in at the uncovered side sections of the drum from being substantially higher than that which actually penetrates the textile material. Therefore, with a constant pump capacity and the same type of material, it is possible to treat material lengths of differing widths with an essentially unchanged rate of liquor flow across the conveying surface of the sieve drum. This means that the washing effect for relatively narrow and dense textile materials is essentially the same as for wide material lengths which cover practically the entire drum surface.
  • the liquid level outside the sieve drum is shown to be considerably higher than within the sieve drum.
  • a resistance to flow must be overcome. This flow resistance is very low when the outer jacket surface is not covered by textile material so that in accordance with the curve shown by the dashed line between the outer andinner jacket designated by reference numeral 16, the liquor or any other fluid-will flow through the conveying surface of sieve drum, that is, the outer jacket without encompassing very much resistance.
  • the inner perforated jacket is provided and since it exhibitsa higher resistance to that of the outer jacket, the liquor will now flow through this inner jacket, and due to this higher resistance, the flow is represented as further illustrated by that portion of the dashed line extending within the inner jacket. As thus illustrated, a substantially higher resistance must be overcome.
  • the situation and operation is quite different when the outer jacket of the sieve drum is covered by the textile material to be treated (which is designated by the reference numeral 6). In this case, the liquor requires increased pressure in order to be able to flow through the material at all, and for this reason the curve shown by the solid line 15 between the inner and'outer jackets is drawn in only well below the curve shown by dashed line 16.
  • the curves represented by lines 15 and 16 are schematic illustrations of the pressure drops taking place as the fluid passes through the outer and inner jackets depending upon whether a textile material is present. After overcoming the resistance caused and greatly increased by the presence of the material 6, the liquor will then flow without encountering a larger resistance through the inner jacket to the height of the level within the sieve drum. This, as noted above, is illustrated by the solid line 15. (The vertical distance from the upper level to the lower level represents the total pressure drop and the portions of the curves between the inner and outer jacket represent the pressure drops effected before the liquor passes through the inner jacket.)
  • FIG. 1 also shows that the clearance between the outer sieve drum jacket 3 and the inner sieve drum 3 jacket 4 is subdivided into annular sections by means of ring-shaped straps 17 which are arranged parallel to thefront edge of the drum. This ensures the avoidance of any liquor level equalization over large sections of the clearance.
  • a device of this kind comprises a heat-insulated housing 20 which is subdivided by a partition wall 21 into a treatment chamber 22 and a fan compartment 23.
  • sieve drums 24 are arranged, which are subject to a suction draft.
  • perforated plates 25 are installed above and underneath the sieve drums 24.
  • fan wheels 33 are disposed within the fan compartment, each of which is adjoined to a specific sieve drum.
  • radiators 26 which are installed above and underneath the fans 33.
  • a drive 27 for driving the sieve drums 24 as well as another drive 28 for driving the fans 33 are each mounted to the outside of the housing 20.
  • baffle plates 29 are provided which screen this portion of the drum surface from the suction draftf
  • the clearance between the outer drum jacket 3 and the inner drum jacket 4 is subdivided into axial extending sections by means of straps 30.
  • the material to be treated is fed to and discharged from this device by conveyor belts 31 and 32.
  • the conveyor belts can be replaced by a pair of intake rollers at the inlet end and a chute or a pair of discharge rollers at the discharge end of the device.
  • the fan 33 By means of the fan 33, a negative pressure is produced in the well known way within the sieve drum, which makes the material adhere to the sieve drum and ensures at the same time an intensive penetration of the processing medium through the textile material length.
  • the processing medium is exhausted by means of the fan 33 and forced back into the treatment chamber via heating means 26.
  • the sieve drums shown in FIGS. 4 and 5 may also be subdivided into sections by means of ring-shaped straps.
  • straps 17 in the embodiment of FIG. I or axially extending elements 30 in the embodiment of FIG. 5 it willbe understood that straps l7 and elements 30 are useful in the preferred embodiments of the apparatus. However, these straps and elements are not required for operation of the invention.
  • rings or straps 17 it will be understood that since the inner and outer jackets of the sieve drum means are passed through by the treatment medium substantially in the radial direction, the rings can only prevent a through-flow of the fluid, particularly liquid, medium between the two perforated jackets in the axial direction of the sieve drum means.
  • the flow component in the axial direction is extremely small so that the rings or straps 17 exhibit only a relatively small effect on the over-all flow-through of the fluid through the sieve drum.
  • the spacing or passage formed between the two jackets also provides a resistance to axial flow thus facilitating the radial flow through the perforations of the inner and outer jackets.
  • the primary function of the straps 17 is for the prevention of the axial component of the liquid between the inner and outer jackets which occurs in the zone of the marginal sections of the material on the section of the outer jacket which is not covered by the ma terial being treated. Because of the close spacing of the inner and outer jackets and because the greater component of the fluid flow is in the radial direction, the presence of straps 17 is not essential. for operation of the subject invention.
  • An apparatus for treating lengths of fluid permeabIe materials which comprises a treatment chamber adapted to contain a fluid treatment medium, at least one sieve drum means rotatably disposed within said treatment chamber, said sieve drum means having an inner and an outer perforated jacket means, said outer jacket means providing a perforated conveying surface for the material to be treated and said inner perforated jacket means being spaced inwardly from and closely adjacent to said outer jacket means, inlet means for in troducing the material to be treated to the treatment chamber so that at least a portion of the width and the periphery of the conveying surface is covered by said material, means for rotating said sieve drum means, at least one means for circulating the fluid treatment medium from the outside to the inside of said sieve drum means, thereby penetrating the material being conveyed thereon, and outlet means for removing the material from the treatment chamber; said inner perforated jacket means providing a greater resistance to the flow of the fluid treatment medium therethrough than the resistance provided by the outer perforated jacket means and said inner perforated
  • the treatment chamber is a liquor container adapted to contain a treatment liquor and the sieve drum means is at least partially disposed in said liquor container whereby a liquor level is provided in the container and in the sieve drum means.
  • roller means are operatively associated withthe sieve drum means to ensure contact of the material with a substantial portion of the periphery of the conveying surface.
  • a lateral collecting vessel is disposed at one end of the liquor container, said collecting vessel communicating with the interior of the sieve drum means and said means for circulating said fluid treatment medium including a pump means within said collecting vessel for circulating the treatment liquor from within the sieve drum means to that section of the container outside of the sieve drum means.
  • the treatment chamber is a heat-insulated housing which is subdivided by a partition means into a treatment chamber and a fan chamber.
  • the treatment medium is a gaseous medium and the means for circulating the treatment medium is a fan means disposed in the fan chamber.
  • heating means are disposed in the circulation zone of the treatment medium.
  • baffle means are disposed within the sieve drum means at that portion of the periphery of said sieve drum means which is not covered with the material being treated.
