Definitions
- the invention relates to a device for dewatering a fibrous web, especially a paper or cardboard web, by expelling of water by gas pressure, with at least one radially through at least one four parallel rollers and axially through sealing units limited pressure space into which a compressed gas can be introduced and through which the fibrous web can be passed through.
- BCP press Bact Cluster Press
- DE-A-199 46 971 Such a so-called BCP press (Beck Cluster Press) is for example known from DE-A-199 46 971. Since this is a relative one new technology is still involved in its practical implementation Space for further optimization measures.
- the aim of the invention is therefore a device of the type mentioned Art to create the one with the simplest possible structure reliable operation guaranteed.
- a device for Drainage of a fibrous web in particular a paper or Cardboard web, by expelling water by gas pressure, with at least one radially through at least four rollers arranged in parallel and axially delimited by sealing units in the pressure chamber Compressed gas can be introduced and through which the fibrous web can be passed is, the rollers and the sealing units at least partially are individually axially adjustable.
- rollers and sealing units can change according to the respective Expand the specific amount of heat and heat absorption individually and thus have an individual behavior.
- the rollers and Storage units can now be set, for example, that there is always as little deviation as possible in the total length of the Roll package results. It is therefore always an optimal side seal of the pressure space possible. So it can be different Thermal expansion of the rollers and the sealing units at least essentially compensated and optimal reliable operation guaranteed to the press.
- rollers are a device by means of a control and / or regulating device axially adjustable so that a possible gap between the respective roller ends and the respective sealing unit if possible is kept low.
- the rollers can be axially controlled by means of the control and / or regulating device For example, be adjustable so that a possible deviation of the Total length of the roller arrangement of a predetermined target length if possible is kept low.
- a zero point setting is therefore particularly advantageous Rolling or a zero point control or regulation possible.
- Position signals are axially adjustable accordingly. It can a position sensor at each end or pin of a respective roller be assigned.
- rollers are advantageously by means of the control and / or regulating device axially adjustable so that their axial centers are at least essentially always in a common, perpendicular to their axes Level.
- the sealing units provided on both sides of the roller arrangement can preferably be controlled independently of one another and / or individually adjustable.
- the rollers can at least partially have a conventional structure possess, through which deflections are compensated. So it is for example a crown or a roller with one around one Carrier encircling, oil-supported floating jacket conceivable. In principle, however, the use of at least one shoe press unit is also necessary or shoe press roller possible.
- the rollers can at least partially cambered, for example, as a deflection compensation roller formed and / or formed by a shoe press roll.
- Device is on both sides of the roller assembly, respectively a housing is provided in which the relevant roller ends or journals assigned roller bearing units and the relevant sealing unit are included.
- the roller bearing units can each be floating in the relevant housing. It is for example, the storage units each have a hydrostatic Store the storage unit in the relevant housing.
- roller bearing units are advantageously constructed and the same each designed as a fixed bearing.
- rollers and / or sealing units are expediently over respective piston / cylinder units individually axially adjustable.
- Each sealing unit is preferably each with a flexible sealing arrangement Mistake.
- the sealing units can each one include a dog bone shape seal.
- the sealing units provided on both sides of the roller arrangement or sealing arrangements are preferably identical, which further reduces manufacturing costs.
- FIG. 10 shows a schematic partial representation a device 10 for dewatering a fibrous web, in particular a paper or cardboard web. It is a so-called BCP press, in which the dewatering of the fibrous web by expulsion of water by means of gas pressure.
- the device 10 comprises at least one pressure chamber 12, which is radial through at least four rollers 14 arranged in parallel and axially through lateral sealing units 16 is limited.
- a compressed gas can be introduced in the pressure chamber 12 through which the fibrous web is passed.
- the rollers 14 and the sealing units 16 are each individual axially adjustable.
- the rollers 14 are by means of a control and / or Control device 18 preferably axially adjustable so that a possible Gap between the respective roller ends and the respective sealing unit 16 is kept as low as possible.
- the respective position of the rollers 14 are detected.
- the rollers 14 are dependent axially adjusted accordingly by the received position signals.
- each end or a position sensor for each end pin 34 of a respective roller 14 22 assigned.
- the rollers 14 can be controlled by means of the control and / or regulating device 18 For example, in particular be set so that their axial centers at least essentially always in a common one Axes are perpendicular to the plane.
- the sealing units provided on both sides of the roller arrangement 16 can be controlled and / or controlled independently of one another individually adjustable.
- the rollers 14 can have a conventional structure to prevent deflections compensate.
- a respective crowning or a respective roller with one rotating around a carrier floating, oil-assisted jacket possible.
- at least one shoe press unit, in particular Shoe press roller is however also conceivable, at least one shoe press unit, in particular Shoe press roller.
- the rollers 14 can at least partially cambered, for example, as a deflection compensation roller formed and / or by a shoe press unit or shoe press roller be educated.
- roller bearing units 26 and the relevant sealing units 16 are included.
- the roller bearing units 26 are each floating in the respective one Housing 24 stored. You can e.g. via a hydrostatic Bearing unit 36 can be mounted in the relevant housing 24.
- the roller bearing units 26 can have the same structure and each include a fixed bearing 38.
- the individual rollers 14 can for example be hydraulic or pneumatic piston / cylinder units 28 and the sealing units 16 for example via hydraulic or pneumatic piston / cylinder units 30 axially adjustable.
- the sealing units 16 can each have a flexible sealing arrangement 32 include.
- the sealing units 16 or sealing arrangements 32 can each have the shape of a dog bone own seal.
- the sealing units provided on both sides of the roller arrangement 16 or sealing arrangements 32 are preferably the same executed.
- the individual rollers 14 can thus, for example, on the individual Piston / cylinder units 28 are adjusted in the direction of their longitudinal axis become.
- the lateral sealing units 16 can also be used, for example by means of piston / cylinder units 30 in the direction of their longitudinal axis be moved freely.
- the advantage of this concept is that everyone Roller 14 and each sealing unit 16 each freely according to their expand specific heat quantity and heat absorption and can behave individually.
- the roller 14 including the associated Bearing units 26 can now by means of the cylinder or piston / cylinder units 28 can be set so that there is always one results in the smallest possible deviation in the total length. So it's one so-called zero point adjustment possible.
- the deviation is calculated using of a control circuit assigned to the control and / or regulating device 18 controlled accordingly, which detects the respective position of the rollers 14 and this via the zero point control with regard to the smallest Corrects the deviation in the length difference.
- the roller bearing itself can be designed conventionally or as a hydrodynamic bearing his. The use of the same components enables in particular also an inexpensive production of small series. Also on the left and right side sealing units 16 or sealing arrangements 32 can be designed the same, since these can be used separately in the relevant housing 24.
- the roller drive can be done directly or indirectly, depending on the coupling concept is provided (hydraulic clutch, sliding clutch, etc.).
