Definitions

  • the invention relates to a screen drum device for drying permeable Goods webs, in particular textile goods such as woven fabrics, knitted fabrics, tissue, Nonwovens or the like with a housing in which at least one rotatably mounted sieve drum on and assigned a pump device such as a fan on the end face is, which sucks the gaseous drying medium from the inside of the drum and feeds outside of the screen drum again, the screen drum outside one fixed perforated screen or a fixed one cylindrical, sieve-shaped body for flow equalization of the inflowing drying medium is assigned.
  • a pump device such as a fan on the end face
  • Sieve drum dryers are known in a wide variety of designs.
  • the normal construction goes z. B. from the utility model G 87 00 837, after which Four sieve drums are arranged next to each other in a row, and above and below this row a sieve cover extends straight.
  • the fans of everyone Sieve drum blow both up and down, so that the circulated Air flows through the sieve cover to the neighboring sieve drums becomes.
  • the screen covers can also be bent centrally around the drums, as disclosed in DE-A-39 05 001.
  • dryers with only one are also known Screen drum.
  • Screen drum In addition to the sieve drum arrangement, dryers with only one are also known Screen drum.
  • z. B the construction according to DE-A-43 25 915 in the right Angle curved screen cover or also according to DE-A-30 06 758 with several Sieve drums in a housing with sieve covers assigned to a segment of a circle or according to DE-A-21 16 486 with an exactly centrally arranged screen cover on one To name the device again with only one sieve drum.
  • the first screening drum is said to be be arranged in a row with a sieve cover, the width of is provided with a different permeability, namely by over one Part of the working width increases the permeability of the storage ceiling to a maximum increase.
  • This is supposed to be a narrow one when the machine starts up Material web with full force of the incoming drying air on the sieve drum be kept.
  • two screen covers to be arranged one above the other and mutually displaceable, namely along the side the working width.
  • the object of the invention is to optimize the known screen drum dryer.
  • the fact of poorer air permeability should be tried wet goods and also the better air permeability of the dryer goods to be taken into account during the drying process or on the hood construction.
  • the fixed screen cover along its length in the housing i.e. seen in the direction of transport of the textile goods a progressively more open area / area unit containing perforation Mistake.
  • the construction of the sieve plate surrounding the sieve drum within the hood alone controls the supply of drying air to each point of the rotating sieve drum in such a way that the air provided by the fan and evenly distributed around the sieve drum in front of the sieve plate at the respective point of the actual drying condition can also penetrate through the goods.
  • diagram no. 3 shows the actual air velocity v through the goods depending on the drying condition.
  • the maximum achievable air speed through the goods is made possible by the construction of the screen cover, depending on the circumferential angle 0 ° at the inlet to 270 ° at the outlet of the goods, depending on the drying condition.
  • the construction of the screen plate can be of different types. Can with advantage the perforation holes over the surface of the sieve cover have a constant diameter have, but the distance of the holes progressively from the entrance area become smaller until the dryer exits.
  • the screen plate is not for economic reasons can be punched continuously with changing distance, it makes sense to Divide the screen cover into individual sections over the length of the device and in a sieve cover with a constant free air passage cross-section in each section to be arranged, however, if necessary, the following in the transport direction of the textile goods To provide the sieve cover section with a higher free air passage cross section.
  • the same goal can also be achieved with two parallel to each other sliding sieve plates can be achieved.
  • a conventional sieve drum device consists of an approximately rectangular housing 1, that through an intermediate wall 2 into a treatment room 3 and a fan room 4 is divided.
  • the screening drum 5 is concentric this in the fan chamber 4 behind a nozzle star 13, a fan 6 rotatably mounted.
  • the fan compartment can also be in one of the screen drum housings 1 separate, not shown, separate fan housing be arranged. This is e.g. B. in the sieve drum designs according to FIGS. 2 and 3 the case. In any case, the fan draws the inside of the drum 5.
  • a sieve cover 10 is arranged in the treatment room 3, the for the traffic jam and thus for the even distribution over the working width air flowing from the fan 6 in front of the drum 5.
  • the screen cover 10 limits the air inflow area surrounding the screen drum, which in the case of FIG. 2 and 3 can also be called a hood.
  • the sieve drum is not from Textile-covered area inside by an inner cover held on the axis 14 8 covered against the induced draft.
  • the drum 5 is of fine mesh on the outside Sieve 9 wrapped around the front of the drum on the two Bottoms 11, 12 is kept taut.
  • a so-called high-tech drum system is indicated, where the only a screen drum 14 is surrounded by a hood 13, which is not by an external Fan shown, the drying air 16 flowing through the screen drum 14 is supplied is.
  • the screen cover 10 'surrounds the screen drum 14 concentrically and limited thus the hood 13 in the direction of the sieve drum 14 Area is the screening drum 14 against the suction through an inner plate 15 covered.
  • Fig. 3 is only the screen drum 14, which rotates counterclockwise here, and the screen cover 10 'assigned to it is shown.
  • the screen cover 10 ' is in over its length divided several fields, each just manufactured and around the hood 13 the drum 14 are attached in segments.
  • a field 1-6 comprises about three segments.
  • the perforation of all segments shows holes 18 with the same in rows of holes Diameter.
  • the spacing of the rows of holes differs in fields 1 - 6.
  • the distance between the rows of holes is selected so that that only a small amount of air can penetrate through the open area.
