Definitions
- the invention relates to a device for the treatment of a paper, cardboard, tissue or another fibrous web in which the fibrous web alone or together with at least one support band, in particular a drainage band, a Press belt, a screen belt and / or the like over at least one moving or stationary support surface is guided and facing away from the support surface
- Side of the fibrous web at least one sealing device is provided which comprises a received in a holder sealing element, which in the immediate Proximity to the support belt is arranged, wherein the sealing element laterally, d. h., across to the web running direction, can be led out of the holder and both on his is stored first and on its second longitudinal side.
- this object is achieved in that the sealing element its first longitudinal side fixed in the holder and on its second longitudinal side in a rotatable receptacle is mounted, in turn, from the holder is included.
- the forming a wear part Sealing element can be easily pulled laterally out of the holder, without any adjoining facilities of the paper machine, in particular an adjacent stabilizer box or the like must be removed with. At most, before pulling out the sealing element, a lateral seal, a side cover or a side air knife are removed, however is possible with little effort.
- the sealing device can, for example, in the region of a particular in one Press section or a dryer section used ventilation equipment such as in particular a steam box, a suction box, a stabilizer, Ventilation internals or the like may be provided.
- the invention provides an adjustable sealing gap is created by a Change in negative pressure does not change significantly.
- the sealing element, the support band, the Woven fibrous web not touched.
- the change of the sealing plate of the leader page of the paper machine possible without interfering with the machine itself to have to.
- the sealing plate or the sealing element in extended, more relaxed Form is replaced, it can also be used to stiffen parts of the paper machine to be pulled around. This means that a change is also inaccessible Setting the paper machine is possible.
- a simple form of attachment of the sealing element results from the fact that this is insertable on its first longitudinal side in a first slot, the is arranged directly adjacent to the receptacle in the holder.
- sealing element its second longitudinal side is insertable into a second slot which is under a acute angle to the radial direction of the rotatable receptacle arranged on this is.
- the sealing element is by the movable attachment to the one Long side on the one hand and attached to the other longitudinal side on the other Fixed attachment via a contact pressure so acted upon, that it from the Maintenance or change position can be arched out to the support band, so that it occupies its operating position.
- the sealing blade clamped on the edge in the holder and in the holder is in relaxed state preferably even; but it is also possible that they are light is arched.
- the rotatable receptacle is advantageously in one by one pneumatic or hydraulic device introduced movable carrier. The Recording can be through such a device at any time in the desired Move position. Alternatively, a movable device with a Electric motor feasible.
- the sealing element can be locked by a lock, For example, by pin, secure against lateral slipping.
- a lock For example, by pin, secure against lateral slipping.
- the sealing element equipped with a camber so, viewed across the machine width, has a different distance from the support band.
- Such a crowning can be realized that either the slot in the holder or the Slit in the rotatable holder a curved, d. H. to the middle of Paper machine has concave or convex curvature. Also both slots can be equipped with a curvature.
- the sealing element may in particular made of plastic, for. B. one glass fiber reinforced plastic, from a fluorocarbon or the like, or consist of a metal.
- the sealing element may extend over the entire width of the paper machine or else extend only over a part or divided in width into at least two zones be.
- the Holder or the stabilizer box two sealing devices in Web running direction are arranged one behind the other.
- the one sealing element or one Dichtspalteinsteller comprehensive sealing device can thus not only as Sealing between two vacuum or vacuum zones with different Use negative pressure, but also as a seal between a vacuum or Underpressure zone and under normal atmospheric pressure environment. Consequently There are a total of three possibilities for the use of the sealing device: Sealing against the ambient pressure, for separating two vacuum zones or in a combination of two sealing devices, one of which is for Sealing against the ambient pressure and the other for separating two Vacuum zones serves.
- the sealing device in the case of Sealing against the ambient pressure instead of a previously used Sanding seal, a flexible, floating seal, a mechanical Sealing strip or an air knife regardless of the negative pressure on the support band can be pressed.
- Another use or another with the sealing device pursued purpose consists in stripping a adhering to the support band Air boundary layer.
- Fig. 1 shows a schematic partial view of a drying section of a device for Treatment of a fibrous web with two in the area of a drying cylinder provided seals in the upper part of a stabilizer box to form an upper and a lower vacuum zone.
- the device is for treatment a fibrous web 10 such as in particular a paper and / or board web.
- a support belt 16 is guided, in the present case by a Drying wire is formed.
- a first seal 24 provided on the side facing away from the support surface 18 side of the fibrous web 10 and the Support band 16 is in the web running direction L before the drain region A.
- This first, inlet side seal may be For example, a flexible, floating seal, a mechanical Sealing strip or an air knife act.
- the seal 24 is a sliding seal. Of the From her to the support band formed sealing gap or the degree of contact pressure on the Support band 16 is dependent on the negative pressure.
- a arranged second sealing device 26 is provided so that an upper and a lower vacuum or vacuum zone 28 and 30, respectively.
- the lower vacuum zone 30 serves to stabilize the web guide.
- the upper vacuum zone 28 serves as a separation zone. Overall, by the arrangement a controlled detachment and stabilization of the fibrous web 10 possible.
- the sealing device 26 comprises a serving as in the holder Stabilizer box 20 received sealing element 32 (Fig. 2), for example in Shape of a flexible sealing blade.
- This is stored in a rotatable receptacle 34.
- This is designed as a shaft with a substantially circular cross-section.
- a slot 36 for insertion of a longitudinal end of the Sealing element 32 attached.
- the slot 36 is at an acute angle to Radial direction of the receptacle 34 stored.
- the other longitudinal end of the sealing element 32 is a slot 38 mounted, the disposed immediately adjacent to the receptacle 34 in the stabilizer box 20 is.
- the receptacle 34 is rotated in the direction of an arrow D, so that the sealing element 32 wound on the circumference of the receptacle 34.
- the Receiving 34 is further rotated until the sealing element 32 in the slot 38th can engage.
- the snap action is either initiated manually or it is mechanical Einrast Anlagenn present, for example in the form of a rod, the is pressed against the free lower longitudinal end of the sealing element 32 until this is pushed into the slot 38.
- FIG. 5 In a further embodiment of the invention (Fig. 5) is provided that on a Stabilizer box 40 instead of the seal 24 (see Fig. 1) according to the invention as the sealing device 26 designed sealing device 42 at the upper end of the stabilizer box 40 is arranged to a negative pressure area below the the sealing device 42 from the ambient pressure above the Separate sealing device 42.
- a stabilizer box 44 is provided two sealing devices 46, 48 arranged one behind the other.
- the Sealing device 46 is attached to the upper end of the stabilizer box 44 and, like the sealing means 42, serves to seal a zone 50 the ambient pressure, while the lower sealing device 48 two zones 50, 52 separated from each other with different negative pressure.
