Definitions
- the invention relates to a suction or blowing device with a moving, Material surface with perforations, in particular on the jacket of a suction or Blow roller, adjacent negative pressure or positive pressure zone, especially in a machine for making a paper, cardboard, tissue or other Fibrous web, the negative pressure or positive pressure zone with at least one Sealing device, which is adjacent to the moving material surface, is equipped, wherein the sealing device cooperates with the moving surface has first upstream and second outflow sealing strips.
- Such sealing devices are used for lateral sealing of at least one overpressure or underpressure zone in a Paper machine with at least one opposite the moving surface Sealing element, a holding element associated therewith and at least one Load element through which the sealing element can be pressed against the moving surface is.
- these sealing devices are used both in the forming section and also in the press section and / or dryer section of a paper machine Use, where they are used, among other things, in suction rolls or blow rolls can be.
- Suction rolls usually have fixed internal ones Suction boxes that form zones of different pressure levels, with the seal the pressure zones is carried out by sealing strips, which are usually at least in extend substantially over the entire length of the roller.
- Noise dampening chamber present between the sealing strip on the outlet side and a further additional one which is distant from it in the circumferential direction Sealing strip is arranged.
- the noise reduction chamber communicates via at least one connecting line with the surroundings of the suction roll.
- This task is carried out in a suction or blowing device of the type mentioned solved in that in the vicinity of the negative pressure zone or the positive pressure zone a device for introducing a fluid or for sucking off a fluid is arranged.
- This device can be outside and / or inside the roller lie.
- the pressure gradient in the area before, around and after the Sealing elements reduced. So that are reductions of the arising Airborne noise emission achievable.
- a fluid for example air.
- the fluid can flow axially over the entire Roll length or only be introduced in partial areas.
- This fluid causes the evacuated perforation of the moving surface, for example, the jacket perforation, not, as usual, mostly abruptly from Internal volume, but preferably filled with the introduced fluid in a controllable manner becomes. This reduces the pressure gradient and thus the resulting one Airborne noise.
- the use of the invention results due to the reduced, stochastically distributed Pressure gradients for a significant reduction in airborne noise emissions in one Machine for the production of a fibrous web.
- the device on the upstream or sealing strip on the outlet side is particularly advantageous if the device on the upstream or sealing strip on the outlet side. This means that the facility in the in the immediate vicinity of the sealing strip (inside and / or outside) is.
- the Device extends over the entire width of the suction or blowing device.
- suction or blowing device between one of the outer surface of the suction or blowing roller felt, sieve or a paper, cardboard, tissue or other fibrous web and the Shell surface of the suction or blowing roller in the direction of the longitudinal axis of the suction or Blow roll tube arranged from which a fluid towards the Drain bar can be inserted or extracted from the direction of the drain bar.
- an axially extending tube can also be inside the roll be arranged, via which a fluid can be introduced in the direction of the drain bar or is suctioned off from the direction of the drain bar.
- a suction roll 1 has one with continuous (here only in places indicated) perforations 2 equipped, rotating roller jacket 3.
- a paper web 4 runs over the jacket 3 in the direction of an arrow A.
- a stationary suction box 5 is arranged, which Inner surface of the roll shell 3 touched by sealing strips 6 and 7.
- the sealing strips 6, 7 are each part of sealing devices as they are are known. For this purpose, reference is made, for example, to DE 198 42 837 A1.
- a blow roller with an inside according to Art of the suction box arranged blow box can also be used pipes How the pipe 8 can be placed in front of and / or behind the blow box to hold a fluid bring in or suction.
- a fluid in particular Air, either extracted or blown in, to produce noise effects such as those at the Production of a fibrous web arise.
- a plurality individual suction or blowing devices are provided, in particular individual pipes with openings or holes, the openings are each in Point towards the sealing device.
- the suction and / or extend Blowing devices in particular a suction pipe or a blowing pipe only via one Part of the roller.
- the invention can be used both in the former and in the Press section and / or in the dryer section of a machine for processing a Insert fibrous web.
