Definitions
- the invention relates to a suction or blowing roller with a rotatable, perforated Roll shell and at least one suction or blowing zone, these from one to Roll jacket open pressure chamber formed inside the roll shell is, which is sealed to the roll shell via at least one sealing element.
- rollers have long been known and in particular in machines for Manufacture and / or finishing of paper, cardboard, tissue or other Fiber webs in use. It happens because of the relative movement between the roller jacket and the sealing element to a high wear and tear considerable pollution with water, fiber residues, etc., which increases the service life reduced.
- the object of the invention is therefore to develop a simple sealing element, which leads to noise reduction.
- the object was achieved in that the sealing element is at least partially designed as a brush seal.
- the sealing element is at least partially designed as a brush seal.
- the sealing element should also be designed exclusively as a brush seal become.
- the brush hair of the brush seal consist of an elastic material at least in a non-fixed section.
- suction or blow roller is significantly simplified if the Pressure chamber is executed stable.
- FIG. 9 shows a schematic partial cross section through a pressure chamber 9 of a suction roll.
- suction rolls are often used in paper machines for dewatering and Support the guidance of the fibrous web on an air-permeable belt in the Area of the former, the press section and the dryer section. there it suffices to form a suction zone in the looped area of the suction roller.
- the roll shell 7 of the suction roll has a perforation 8 in the form of through holes.
- a inside of the suction roller pressure chamber 9 sealed off from the other interior Pressure chamber 9 is connected to a vacuum source and thus causes that Sucking in of outside air through the perforation 8 in the area of the pressure chamber 9 This creates the suction zone, the water from the fibrous web or the usually between the fibrous web and suction roll in the belt Suck the inside and guide the fibrous web in the looping area improve.
- the sealing of the positionally stable pressure chamber 9 towards the rotating roller jacket 7 takes place via a brush seal.
- the brush seal consists of many Brush hair 1, which are held together by a dimensionally stable version 2.
- the free ends of the brush hair 1 are here against the inner surface of the roll shell 7 pressed. This is done using a compressed air supply Compressed air hose 4, between the socket 2 and a U-shaped guide 5 for the sealing element is arranged.
- the ends of the brush hair 1 are included coated with an abrasion-resistant material.
- the Brush hair 1 made of an elastic material, so that at least in the middle section 3, which is not fixed by the version 2, sufficient flexibility of the brush hair package is given.
- the guide 5 of the sealing element is fixed to the wall 6 of the pressure chamber 9 connected.
- the brush seal is less susceptible to contamination.
- a blowing zone can be realized simply by using the pressure chamber 9 a pressure source is connected.
- the in the area of the pressure chamber 9 the perforation 8 air penetrating outside can be used for this purpose, for example be, the fibrous web from that between the fibrous web and blow roll to loosen the running tape.
