Definitions

  • the subject invention relates to a device for at least one a screen belt having plant for paper production, which for supporting of the screen belt or for stripping the passing through the screen belt, emerging from the paper pulp or paper tape located on this Water with a plurality of in the direction of movement of the screen belt mutually spaced support or stripping is formed of ceramic material, at the top of the screen belt comes to the plant.
  • a device for at least one a screen belt having plant for paper production, which for supporting of the screen belt or for stripping the passing through the screen belt, emerging from the paper pulp or paper tape located on this Water with a plurality of in the direction of movement of the screen belt mutually spaced support or stripping is formed of ceramic material, at the top of the screen belt comes to the plant.
  • a device is e.g. from EP-A-0 350 827 known.
  • a first area of the Siebbandstrom enters the contained in the pulp Water in particular due to gravity through the wire through.
  • it is for the extraction of water contained in the paper tape water or moisture contained therein required to apply vacuum to the screen belt.
  • the support or squeegee brought to the plant with great pressure. In doing so on the To be able to absorb the forces exerted on the moving belt, the support or squeegee be arranged at a close distance next to each other.
  • the support or squeegee is on the one hand from the Strainer discharged water and comes on the other hand on the Sieve tape applied by the vacuum boxes to the effect of, by which contains the water contained in the pulp or paper tape or the Moisture is sucked off. Due to the support or squeegee must two conditions are met, which, however, are contradictory are. On the one hand, these strips should be arranged as close together as possible be to the required support of the screen belt, in particular in those areas where it is subjected to vacuum, too cause. On the other hand, the support or squeegee in as possible are spaced apart from each other to allow enough room for the derivation of the passing through the sieve belt water and further the largest possible spaces in which the vacuum on the screen belt for Effect comes to achieve.
  • a supporting and stripping device for a Siebband known which with a plurality of individual support or Squeegee is formed.
  • This known device is the task based on arranging and designing the support or wiper strips, that they are height adjustable according to the requirements of the operation are.
  • this device consists of bores Stringer, whereby the holes contain splitting elements, which are arranged adjustable in height. Between the pestle-shaped Elements and the walls of the holes are column or Channels through which the extracted from the pulp water passes.
  • the present invention is based on the object the contradictory demands for maximum support of the screen belt and to maximize the cross sections of Passages to correspond. This is achieved by having one of Width of the screen belt is provided according to wide support frame, which is formed with support strips, to which a plurality of juxtaposed spaced, fixed support or stripping provided is and that between these support or stripping existing Interspaces the passageways for the out of the pulp or the paper tape emerging water or for the through the wire belt form sucked air.
  • the support and stripping elements located at two successive support strips in the direction of movement of the screen belt are offset from one another relative to the direction of movement of the screen belt.
  • the upper edge of the support frame is at least approximately in the surface of the top of the support or stripping.
  • supporting or stripping elements are formed on their upper sides coming into abutment against the wire belt with a wedge-shaped projection protruding counter to the direction of movement of the wire belt, whereby the wiping effect is improved.
  • supporting or stripping elements may be curved on their upper side.
  • the device shown in Fig. 1 consists of a support frame 1, which e.g. intended for mounting on a suction box.
  • This support frame 1 is at its top with a support 11 made of ceramic material formed on which an unillustrated screen belt a system for Paper production comes to the plant.
  • the screen belt is placed over the support frame 1 in the direction of arrow A moved away.
  • the support frame is 1 formed with a plurality of support bars 12, on which upward protruding support or stripping elements 2 are attached.
  • the top of the Support and stripping 2 is located in the plane of the top of Edition 11.
  • the support frame 1 and the plurality of support or stripping elements 2 extend it is over the entire width of the screen belt.
  • the support and Scraper elements 2 are in a plurality of transverse to the direction of movement A.
  • the Siebbandes aligned rows closely next to each other and behind each other arranged, being between the multiplicity of side by side and behind each other arranged supporting and stripping 2 a very large number of interspaces, by which on the one hand from the on Sieve belt located pulp or paper tape emerging water passes and on the other hand that of the suction box on the pulp or the Paper tape applied vacuum comes into effect.
  • FIG 2 embodiment of a device according to the invention differs from the embodiment shown in Figure 1 in that the support and stripping 2 another spatial Have design. These are in against the direction of movement A of the screen belt is formed wedge-shaped tapered projections 21, by which the wiping action with respect to that through the wire belt passing water is improved.
  • the device shown in Figure 3 differs from that shown in Figure 2 Device characterized in that the stripping elements 2a on the Support frame 1a protrude or that the support frame 1a not with a the screen belt is formed to the plant coming top. Such Device is then deployed, if through this only one Supporting the screen belt and a stripping effect is to be achieved whereas no vacuum is applied to the screen belt.
  • FIG 4 eight different embodiments of support and Stripping elements 2 shown. These representations show that the support and stripping 2 have a variety of configurations can. These can be formed with flat or curved surfaces be. In addition, they can counter with the direction of movement of the Siebbandes protruding projections 21 may be provided.
  • the essential feature is the device is that a very large number of supporting and stripping elements 2 is provided, through which the required support of Siebbandes is effected and through which the passing through the screen belt Water is stripped, but also for the derivative of the water and for the action of vacuum on the screen belt a very large area is available, creating a very effective admission is made possible with vacuum.
