Definitions

  • the invention relates to a device for flowing treatment of web-like textile material, fleece, paper, tissue or the like.
  • a liquid, but in particular gaseous treatment agent circulated in the overall device by a fan with a suction-trapped flow from the outside inwards , permeable drum on the front with bottoms as a transport element for the web-shaped material, which is assigned a drum-axially parallel storage cover with perforation holes across the working width of the drum to form the treatment agent storage space in front of the treatment chamber, the treatment agent permeability of which is less than that of the drum.
  • a screen drum construction of this type is known.
  • the stowage cover is necessary in order to distribute the circulated fluid in front of the treatment room, in which the sieve drum is rotatably mounted, evenly over the working width, so that it then flows perpendicularly to the surface of the sieve drum in equal amounts of air flow from the sieve drum. This results in an equal temperature distribution over the working width of the screening drum.
  • the sieve drum jacket can be made from a perforated sheet metal, through which a braided sieve can possibly be looped through the perforation to even out the air flow.
  • the air permeability of this sheet metal jacket is limited to about 45% of the entire surface of the drum because of the webs between the holes necessary for the stability of the jacket.
  • the drums the casing of which is composed of radially extending metal strips.
  • this adjustment possibility is only limited to a small measure of the entire working width, in particular only the edge areas can be covered in order to be able to use the center of the drum. It is bad if e.g. only one edge strip on the outer edge of the sieve drum should remain open, but the remaining area of the sieve drum must be closed.
  • the invention is therefore based on the object of developing a device with which the abovementioned disadvantages can be eliminated.
  • the aim is to be able to fully dry even a narrow strip on the heat treatment drum and thereby solidify it.
  • the system can be easily threaded without having to drive the large material losses that have arisen up to now.
  • the invention provides for the solution of the problem that the degree of permeability of the baffle cover can be temporarily increased to a maximum at least over a portion of the working width. So it should start up the system not the sieve drum is limited in its working width by, for example, inner cover plates in its flow area, but the effective or the particularly effective opening width of the baffle cover is opened to concentrate the flowing air in the necessary width more.
  • a partial area of the storage ceiling is rendered ineffective as a storage ceiling.
  • This is possible by moving this partial area of the storage ceiling over the neighboring one, as a result of which there is no longer any storage ceiling in the partial area, or by providing the storage ceiling in the partial area with a device for increasing the air permeability.
  • This can advantageously consist of pivotable flaps which can be set up in this partial area to open the storage ceiling.
  • the stowage cover is at least partially arranged parallel to and parallel to the axis of the sieve cover, the perforation holes of which are designed to be larger than or at most equal to that of the stowage cover in cross-section in the direction of displacement.
  • a sieve plate which also has a perforation, is only slightly displaced over the storage ceiling, so that, with a limited working width, only the holes that are not required are covered by this additional sieve ceiling. For example, the screen plate only shifts by less than one hole pitch.
  • the production of the web can slowly be expanded to the intended web width.
  • a slight displacement of the screen cover relative to the storage ceiling then causes the corresponding air to flow to the screen drum in accordance with the increase in the working width.
  • the arrangement and the respective size of the perforation in both the sieve and in the storage ceiling are to be dimensioned such that as much as possible 100% of the inflowing amount of air can flow against the drum through the open perforation holes. If only the narrow band has to be dried, the holes to be provided in the area of this band are to be provided with a largest cross-section, while the remaining holes are automatically covered. If the working width is increased after the device has finally started up, the perforation cross-section of the holes in the storage ceiling must be reduced overall in accordance with the increase in the number of holes, so that 100% of the inflowing air can now flow over the larger area to the sieve drum. Ultimately, the previously common ram air should flow evenly over the working width over the entire working width of the screening drum, in that all holes now have a uniform opening cross-section over the working width of the storage and screen ceiling.
  • one or a plurality of radially directed walls are arranged round and at a small distance around the drum between the storage ceiling and the drum. Such walls prevent axially directed incorrect ventilation of the drum.
  • Vorrich device to measure the material web width of the incoming material, which is functionally connected to the sliding device of the screen cover opposite the storage ceiling, in order to match the material width running onto the screen drum exactly with the position of the screen cover relative to the storage ceiling and thus exactly with respect to the open inflow openings .
  • the 1 and 4 consists of a rectangular housing 1, which is divided by an intermediate wall 2 into a treatment room 3 and a fan room 4.
  • a sieve drum 5 In the treatment room 3 there is a sieve drum 5 and a fan 6 rotatably mounted concentrically to it in the fan room 4.
  • the fan space can also be arranged in a separate fan housing, not shown here, which is separated from it.
  • the fan sets the inside of the screen drum 5 via its open face under suction.
  • the application also relates to the drum construction on a wet treatment device, which can also be used only for suctioning off liquid or for wet needling of nonwovens. The overall construction must then be adjusted accordingly.
  • heating units 7 are arranged above and below the fan 6, which consist of pipes through which heating medium flows.
  • the sieve drums are built with the shell structure, which is only of interest here, up to 96% air-permeable and has a very large diameter.
  • the screening drum 5 is covered over almost the entire circumferential surface with the textile material or paper 10 to be treated (FIGS. 4, 8).
  • the inner cover 8 is shown in FIGS. 1 and 4, which in this exemplary embodiment could, however, also be arranged in a fixed manner at the level of the drum axis.
  • a fine-meshed sieve 9, which is only shown in FIGS. 1 and 4 is wrapped around the outside of the drum 5 and is fastened to the two bases 11 and 12 on the end face of the drum.
  • a storage ceiling 13 is arranged around the drum 5 between the housing wall 1 and the intermediate wall 2.
  • the stowage cover extends horizontally, in the case of a single-drum device the stowage cover can also extend around the drum at a constant distance.
  • the screen drum device is about a possibility of being able to dry a web 10 'with a smaller web width within a short time without the screen drum 5 having to be provided with a complex construction to limit the air permeability to the width of the web .
  • this stowage cover 13 which also extends over the entire working width of the screening drum 5, in the area where the narrow web 10 'rests on the screening drum and is to be treated, consists of circular segments 13', which in the case the treatment of the web 10 'is shifted radially outward from its normal functional position and then pushed parallel to the axis of the screening drum over the fixed storage ceiling 13.
  • a device can also be arranged in the free annular surface 13 ′′ with which the air permeability of the storage ceiling 13 can be increased if necessary.
  • this consists of circularly arranged, pivotable flaps 22 which open the storage ceiling in
  • the stowage ceiling 12 - as can be seen in Figure 2 - is bent upwards into a flange in the area of the support of the web 10 '.
  • the respective axis 24 of a flap 22 is mounted in the flanges and can be pivoted with this axis 24
  • the lever mechanism 25 is used for pivoting and can be connected in a simple manner to a corresponding gear for the simultaneous actuation of all flaps 22 around the drum 5.
  • the flaps are 22, as can be seen from Fig. 2.
  • Figure 4 shows that thus extends over the entire working width of the drum 5
  • the flaps 22 are pivoted by 90 ° and thus partially superimposed according to Figure 3. So that air also flows through this area of the storage ceiling in this case, the flaps 22 are provided with a perforation 23 such that the air permeability corresponds to that of the other storage ceiling 13.
  • the flaps are kinked over the surface at the outer ends in order to achieve better positioning of the flaps in the closed state.
  • the levers 25 are then to be pivoted in the direction of the arrows 26.
  • Drum 5 is assigned. Only this strip of material should be dried, while the remaining area of the drum remains unused. Therefore, according to FIG. 6, the remaining holes in the storage ceiling 13 are covered by the webs of the holes in the screen cover 14.
  • the screen cover 14 can also extend in the left area over the storage ceiling. It is then only necessary to align the holes in the storage ceiling with those of the screen ceiling. If the screen cover is shifted to the right (arrow 15), the through openings 21 of the storage cover 13 are opened successively until the shift position according to FIG. 5 is reached and thus all openings are permeable. Accordingly, in FIG. 5 the material web 10 also extends over the entire working width of the screening drum 5.
  • the holes in the stowage ceiling 13 are of a constant size, in particular such that the desired back pressure is created in the storage space.
  • the holes in the sieve cover 14 increase in sections to the left in cross-section, and only in the direction of displacement 16. If the sieve cover 14 is moved to the left (arrow 16), the through holes arranged on the far right first close, then the next group, etc., while the holes on the storage ceiling 13 arranged further to the left remain open because of the elongated holes 17.
  • the openings of the elongated holes 17 can also become continuously larger.
  • FIGS. 7 and 8 are also more advantageous.
  • the perforation holes in the baffle cover 13 as well as in the screen cover 14 are different in their passage cross section.
  • the aim here is to always achieve the 100% permeability to the treatment air through the remaining open holes in the covers, which would be necessary if the screen drum 5 were completely covered with the material 10 according to FIG. Therefore, the elongated holes 17 in FIG. 7 are very large in the area of the narrow material web 10 '.
  • a transverse ventilation of the air flowing in the axial direction to the open flow surface of the screen drum 5 is prevented by walls 18 which extend from the stowage ceiling 14 to approximately the screen drum surface. So only a radially directed flow can arise.
