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 with bottoms on the front as a transport element for the web-like material, which is assigned a drum-axially parallel storage cover with perforation holes across the working width of the drum, across the working width of the drum, to form the treatment agent storage space in front of the treatment room.
  • Permeability 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 optionally 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 are better, the casing of which is composed of radially extending metal strips. These drums, which are permeable up to 96%, are used in particular for drying paper and nonwovens.
  • FR-A-21 51 230 it is also possible to change the permeability of a storage ceiling by displacing a second perforated plate arranged parallel to the storage ceiling laterally relative to the storage ceiling in such a way that at least some of the perforation holes in the storage ceiling are displaced through the sheet is covered. So you can z. B. close a second drying section of a dryer to reduce the performance of the dryer. However, it is not possible to increase the drying capacity of a drying section by means of this device. With the construction according to DE-A-16 35 263, on the other hand, it is possible to concentrate the drying performance on one strip by adjusting the working width of the screen drum through walls or cover plates on the inside of the screen drum.
  • this adjustment option 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, for example, only one edge strip on the outer edge of the sieve drum is to remain open, but the remaining area of the sieve drum has to be closed.
  • the invention is therefore based on the object to develop a device with which the aforementioned 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 threaded without problems, without having to drive the large material losses that have arisen so far.
  • the invention provides, in order to achieve the object, that the storage ceiling has a partial area which is provided with a device for increasing the permeability.
  • the working width of the sieve drum should not be reduced by e.g. inner cover plates are limited in their flow area, but the effective or the particularly effective opening width of the baffle 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 larger in cross-section in the direction of displacement up to at most equal to that of the stowage cover.
  • a screen plate which also has a perforation, is only slightly displaced over the storage ceiling, so that, with a limited working width, only the unneeded holes are covered by this additional screen cover will. 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.
  • only 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 screen and in the storage ceiling are to be dimensioned such that 100% of the inflowing air quantity can flow through the open perforation holes against the drum. 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 the largest cross-section, while the remaining holes are automatically covered. If the working width is increased after the device has finally been 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.
  • the invention further provides that one or a plurality of radially directed walls are arranged round and at a short distance around the drum between the storage ceiling and the drum. Such walls prevent axially directed incorrect ventilation of the drum.
  • a device which measures the width of the incoming material, which is functionally connected to the device for increasing the permeability, in order thereby to exactly adjust the width of the material running onto the screen drum with the position of the screen cover in relation to the storage cover and thus to be precisely coordinated with the open inflow openings.
  • 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 and a fan 6 is rotatably mounted concentrically to this 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 inserts the inside of the screen drum 5 via its open end face.
  • the drum construction is also on a wet treatment device, which are also used only for suctioning off liquid or for the needling of nonwovens may, subject to registration. 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 constructed with the shell structure of only a very large diameter, which is only of interest here, up to 96% air-permeable.
  • the screening drum 5 is covered with the textile material or paper 10 to be treated over almost the entire circumferential surface (FIGS. 4, 8).
  • the inner cover 8 is shown in Figures 1 and 4, which, however, could also be arranged stationary in this embodiment at the level of the drum axis.
  • a fine-meshed sieve 9, which is only shown in FIGS. 1 and 4, is looped 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.
  • this storage blanket 13 which also extends over the entire working width of the screen drum 5, in the area where the narrow web 10 'on the screen drum rests and should be treated there, from circular segments 13 ', which in the case of the treatment of the web 10' moved radially outward from their normal functional position and then pushed parallel to the axis of the sieve 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 circular, pivotable flaps 22 which can be set up in this partial area to open the storage ceiling.
  • the stowage ceiling 12 - as can be seen from FIG. 2 - is bent upward into a flange in the region of the support of the web 10 '.
  • the respective axis 24 of a flap 22 is mounted in the flanges and is pivotally attached to 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 22 are set up, as can be seen from Fig. 2. If, on the other hand, a fabric web 10 is dried, as can be seen in FIG. 4, which thus extends over the entire working width of the drum 5, the flaps 22 are pivoted by 90 ° and are therefore partially superimposed according to FIG. 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 according to Figure 3 at the outer ends of the Surface kinked in order to achieve better positioning of the flaps when closed. To open the flap mechanism, the levers 25 are then to be pivoted in the direction of the arrows 26.
  • a sieve cover 14 is also connected in parallel and directly assigned to it.
  • the screen blanket leaves an area on the operating side (drive side of the drum 5); however, the screen cover 14 can also run through according to the dashed line.
  • the two ceilings 13 and 14 are arranged to be displaceable relative to one another. The displacement serves to change the flow area of the storage ceiling 13 or to open and close the flow openings of the storage ceiling. The aim is to let the air accelerated by the fan pass through the stowage ceiling only where the air can also hit a material 10, 10 'lying on the drum 5. The remaining part of the openings of the screen and dam ceilings should be closed.
  • the area of the storage cover 13 without the screen cover 14, to which the narrow strip of material 10 'according to FIG. 7 is located 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 cover 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 all openings are therefore 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 storage ceiling 13 are consistently large, in particular such that the desired dynamic 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 respectively remaining, open holes in the blankets, which would be necessary if the screen drum 5 were completely covered with the material 10 according to FIG. 5. Therefore, the elongated holes 17 in Figure 7 in the area of the narrow gutter 10 'are very large. There is a lot of air flowing through the narrow, open sieve cover and thus treats the material 10 'optimally, ie that it is dry after the sieve drum 5 rotates is delivered. The holes outside the area of Gutbahn 10 'are closed again.
  • 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.
