Definitions

  • the subject invention relates to a device for cleaning a present in a plant for producing paper felt, which is guided by support elements and which at least one suction device and at least one device for applying the same are associated with a cleaning liquid.
  • plants for paper production are at least one screen belt and at least one in the direction of movement of this subsequent felt belt, which two belts are moved in the plants at speeds of about 30 m / sec over support elements away.
  • a pulp is sprayed.
  • the liquid contained in the pulp is discharged through the wire, in particular sucked.
  • the paper strip produced in this way is subsequently transferred to the felt belt, on which it is dried. Then the paper tape is released from the felt and processed further, in particular further dried and rolled.
  • the subject invention is therefore based on the object to provide a device by which a comparison with known devices more effective cleaning of felt belts is made possible.
  • This object is achieved in that support elements are respectively provided on both sides of the felt belt, which extend transversely to the felt, wherein the arranged on the two sides of the felt belt supporting elements are offset in the longitudinal direction of the felt against each other such that each one on one side arranged support element is located between two arranged on the other side of the felt belt supporting elements and protrudes between them, whereby the felt belt between the opposing support elements is moved in a wave-like course and that is located between two adjacent support elements at least one suction channel.
  • At least one suction channel can be located between the support elements located on both sides of the felt belt.
  • at least one suction channel is located on one side of the felt belt and at least one pressure channel for air, for a cleaning fluid or for a mixture of these two media on the other side of the felt belt.
  • the support elements respectively located on one side of the felt belt are arranged on a common carrier.
  • the support elements may be formed in particular by support rollers, which are mounted in bearing shells, which a flowable medium, such as water or air, can be supplied, whereby they are kept at a distance from the bearing surface.
  • This device consists of two groups of support rollers 1 and 2, which are located on the two sides of a felt 3. Furthermore, between these support rollers 1 and 2 connected to a suction suction channels 4 are provided. Furthermore, the respective support rollers 2 located on one side of the felt belt 3 are offset from the support rollers 1 provided on the other side of the felt belt 3 and protrude into the spaces located between these support rollers 1, whereby the felt belt 3 is moved in a wave-like course , Preferably, the individual support rollers 2 are adjustable in their distance from the support rollers 1 located on the other side of the felt belt 3, whereby the wave-shaped course of the felt belt 3 is variable.
  • a transversely to the movement of the felt 3 aligned spray tube 5 is provided, through which a cleaning liquid 51 can be applied to the felt 3.
  • the cleaning of the felt belt 3 is effected in that by means of the spray tube 5 on the felt 3, a cleaning liquid 51 is applied, which receives the impurities located in the felt belt 3 and which is subsequently sucked through the suction channels 4.
  • the felt belt 3 is cleaned.
  • the cleaning effect is promoted by the fact that the felt belt 3 is moved between the two groups of the support rollers 1 and 2 in a wave-shaped course. As a result, a substantially improved effect is achieved over known devices in the cleaning of the felt 3.
  • the support rollers 1 and 2 are mounted in bearings 11 and 21, which a flowable medium, such as water or air, is supplied, whereby they are lifted from the bearing surfaces and thus are almost smoothly rotated.
  • the shells 11 and 21 provided on each side of the felt belt 3 are fastened by means of screws 61 and 71 to respective common supports 6 and 7.
  • At least one suction channel may be provided on one side of the felt 3 and at least one pressure channel may be provided on the other side of the felt 3.
  • air or a cleaning liquid, in particular water, or a mixture of air and a cleaning liquid can be introduced into the pressure channels.
  • an injection device is not required. This also improves the cleaning effect.
  • the support rollers and support strips may be provided, between which the suction channels 4 and pressure channels are located.
  • the felt strip 3 associated surfaces of the support strips are coated with plates of a ceramic material.
  • Decisive for a device according to the invention is that the felt belt 3 is passed between two groups of staggered and projecting into the respective intermediate support elements, whereby it is guided for its cleaning in a wave-like movement.
  • the structure of the felt belt is constantly changed, whereby the dirt located in this can be easily removed from this, as is the case with previously known systems.
