Definitions

  • the water discharge device is of particular advantage for the drainage of a fibrous web, especially one Paper or cardboard web, serving, at least one in the web running direction extended press nip having press assembly usable after with an extended press nip an increased water volume Must be taken into account.
  • Water drainage devices are throttling the two chambers Openings connected together.
  • Water drainage is the second chamber through a transverse direction extending, vacuum-loaded tube limited, the Jacket is provided with openings through which the first chamber with the is connected by the tube interior formed second chamber.
  • the invention also relates a press arrangement for dewatering a fibrous web, in particular a paper, cardboard or tissue web in a machine for manufacturing and / or refinement thereof, consisting of at least one, of two arranged one above the other and pressed against each other Press nip formed by the press nip, next to the fibrous web at least one drainage belt running above the fibrous web to take up the squeezed water, whereby between the upper press roll and the dewatering belt a water absorption device is arranged.
  • a press arrangement for dewatering a fibrous web in particular a paper, cardboard or tissue web in a machine for manufacturing and / or refinement thereof, consisting of at least one, of two arranged one above the other and pressed against each other Press nip formed by the press nip, next to the fibrous web at least one drainage belt running above the fibrous web to take up the squeezed water, whereby between the upper press roll and the dewatering belt a water absorption device is arranged.
  • a structurally simple connection of the suction channel to a vacuum source results from the fact that the mouth of the suction channel lies above the maximum water level in the collection container and the collection container has a connection for a vacuum source above the maximum water level.
  • the collecting container can also be divided across the fibrous web into several chambers, each with a separate connection for a vacuum source. This enables control, preferably equalization of the negative pressure across the width of the fibrous web.
  • FIGs 1 to 9 each show a purely schematic representation Water discharge device 10 for a paper machine and the like, the can be used in particular for a felted press 12.
  • a double felted press see e.g. Figures 1 and 3 is one Water discharge device 10 can be used in particular for the upper felt.
  • FIG is a schematic cross section through a water absorption device 5 shows.
  • This water absorption device 46 is essentially one, in the gusset between upper press roll 40 and drainage belt 44 protruding and transverse to the fibrous web 38 suction channel 48 formed, which is connected to a vacuum source.
