Definitions

  • the present invention relates to a press jacket for a Press device for dewatering a material web in one Press nip, in particular a paper web in a shoe press, according to the preamble of claim 1.
  • Such a press jacket is known for example from DE-A-4401621.
  • Blind holes have a higher storage volume than grooves, however, the disadvantage that a large in the press nip hydraulic pressure is built up. This disadvantage occurs not with grooves, but only a smaller one Have water storage volume.
  • the invention has for its object a press jacket of the type mentioned at the outset in such a way that a high level is maintained while maintaining sufficient jacket strength or while ensuring good jacket durability Water storage volume with low hydraulic pressure in the Press nip is given.
  • the blind holes ensure a high level Water retention capacity.
  • the hydraulic pressure in the press nip is also reduced, because the blind holes over the grooves with the sections are connected before and after the press nip, i.e. on Atmospheric pressure are connected. That in the blind holes Water absorbed can therefore partially through the grooves drain off, so that the emergence of a large hydraulic Pressure in the blind holes is prevented.
  • the grooves have a length which is larger than the press nip length. This is always connected to atmospheric pressure.
  • the Grooves can also be used across the entire direction of web travel measured press shell length extended grooves and be designed in particular as endless grooves. This is from easy to manufacture and allows connection at the same time several blind holes arranged one behind the other at atmospheric pressure.
  • the grooves can be single, double or Form multiple helix.
  • Helical grooves are also easy to manufacture and improve also the properties of the roll shell.
  • the distances between adjacent blind holes can be in the be essentially the same.
  • the distances adjacent blind holes should not differ from each other by more than 10%. This makes the drainage performance special good and even.
  • the grooves or grooves parallel to each other.
  • the Distances and the width of the grooves or grooves each essentially the same with each other. Even the uniformity the arrangement of the grooves or grooves increases the uniformity the drainage.
  • grooves are less than or equal to the diameter of the Blind holes. This ensures that each blind hole is connected to at least one groove or groove.
  • the width of the grooves or grooves is preferably smaller or equal to the diameter of the blind holes.
  • the blind holes can advantageously the main storage volume for form the water intake.
  • the width of the grooves or grooves can be kept low as it is essentially serve to reduce the hydraulic pressure. A water intake from the paper web through the grooves or grooves basically not necessary so that the grooves or grooves can have a very narrow opening.
  • the depth the blind holes are greater than the depth of the attached ones Grooves or grooves.
  • This configuration is also a result allows the main storage volume through the Blind holes is formed.
  • the grooves or grooves can thereby be formed with a shallow depth as long as only it is ensured that sufficient water from the blind holes can flow out of the press nip area to a high Avoid hydraulic pressure. The strength of the press jacket this increases the risk of breakage or cracking reduced.
  • the blind holes are arranged along lines whose pitch angle ⁇ B to the web running direction is between 5 ° and approximately 15 °.
  • Such an arrangement of the blind holes for drainage has proven to be favorable.
  • the strength of the press jacket is relatively little affected by this and the risk of cracks spreading in the web running direction is reduced.
  • the grooves or grooves follow a line whose pitch angle ⁇ R corresponds to the pitch angle ⁇ B of the blind holes.
  • the grooves or grooves are arranged so that the lines that the blind holes and the grooves or grooves follow coincide. This results in an arrangement in which the grooves or grooves are connected centrally to the blind holes.
  • the water drainage is optimal and the press jacket durability is also good.
  • the grooves or grooves follow a line whose pitch angle ⁇ R is between 0.1 ° and approx. 3 °.
  • the grooves or grooves run at a different angle than the blind holes.
  • the connection of the grooves or grooves to the blind holes varies here via the press jacket.
  • the open area of the roll shell in the press area is preferably more than 30% of the total area of the press jacket in this area. This advantageously makes a high one Drainage performance guaranteed.
  • the Blind holes at least two different diameters.
  • the blind holes with different diameters preferably evenly over the surface of the press jacket distributed, in particular by using blind holes Larger and smaller diameters arranged alternately become. This will increase the water absorption without excessive reduction of the webs between the blind holes and thus achieved without too much loss of strength.
  • the blind holes 1 of this variant of a press jacket according to the invention are evenly distributed over the surface 2 of the press jacket.
  • the blind holes 1 each have essentially the same distances a 1 , a 2 , a 3 from the adjacent blind holes 1.
  • the deviation of the distances a 1 to a 3 is approximately 10% or less.
  • the blind holes 1 are arranged along lines 3 which enclose an angle ⁇ B with the web running direction 4.
  • the angle ⁇ B is preferably between approximately 5 ° and approximately 15 °.
  • the grooves or grooves connected to the blind holes 1 are not shown in FIG. 1.
  • Fig. 2 shows an embodiment of the press jacket according to the invention, in which the blind holes 1 are also arranged along lines 3, which have an angle between approximately 5 ° and approximately 15 ° to the web running direction.
  • the blind holes 1 there are grooves 5, which likewise run along lines 6, which enclose an angle ⁇ R between approximately 5 ° and approximately 15 ° to the web running direction 4.
  • the lines 6 coincide with the lines 3, so that the grooves 5 are each connected centrally to the blind holes 1.
  • the grooves 5 are at the same distance D from one another and the width b of the grooves is smaller than the diameter d of the blind holes 1 same distance a 1 , a 2 , a 3 .
  • the grooves 5 are also parallel to each other arranged at the same distance D.
  • the distance D between the edges of adjacent grooves 5 is approximate equal to or less than the diameter d of the blind holes 1.
  • the blind holes are not on lines 3 that with the lines 6, along which the grooves 5 extend, coincide, this ensures that each blind hole 1 is connected to at least one groove 5.
  • the grooves 5 can be formed in all exemplary embodiments, in particular as endless grooves or as helical grooves.
  • the grooves 5 can also form a double or multiple screw line.
  • the blind holes 1 can be evenly or randomly distributed over the surface 2 of the press cover. Their depth is preferably greater than the depth of the grooves 5.
  • the grooves 5 can also form a small angle ⁇ R with the circumferential direction 4, in particular between approximately 0.1 ° and approximately 0.3 ° ,
  • the open area of the roll shell resulting from the sum of the opening cross sections of the blind holes 1 and the grooves 5 is preferably more than 30% of the total area, at least in the area of the press nip.
  • the overall result is a press jacket with very good drying properties, because of a very good water absorption and drainage given is.
  • the blind holes 1 ensure in particular for a large storage volume and the grooves 5 for removing the water from the press nip, so that the Creation of a high hydraulic pressure in the press nip is avoided.
  • the production of the press jacket according to the invention is comparatively simple, and the press jacket is characterized by a high durability.
