Definitions
- the invention relates to a roller press, preferably for treating a running web, e.g. Paper web.
- the roller press comprises two press units, e.g. Press rolls, the main axes of which lie in a press plane and which together form a press nip through which the web runs.
- the roller press can also comprise three press units, which form two press nips, or four press units, which form three press nips.
- Di6 invention is based on a roller press with the features specified in the preamble of claim 1.
- the "main axis" of a press unit can be, for example, the axis of rotation of a press roll shell or the longitudinal axis of the stationary support body, for example a shoe press unit (in the latter case, the axis of rotation can be arranged eccentrically to the main axis).
- the "circumferential Preßele ent” can be a metallic press roll jacket, which is rotatable about a stationary support body and displaceable relative to this in the radial direction, or a press belt or a tubular press jacket, if it is a shoe press unit.
- the "internal pressure device 11 can either be a semi-annular pressure chamber or a series of radially movable support elements or an elongated radially movable press shoe.
- the "a press unit”, the bearing blocks of which are rigidly supported, stands on a frame, foundation or the like, or is attached (by means of its bearing blocks) to a (for example vertical or horizontal) support.
- the "other press unit” can be arranged above, to the side or below the rigidly supported press unit; their weight is carried by the pedestals of the rigidly supported press unit.
- the expression “rigidly supported” also includes the two-part bearing block construction with axial guide elements, for example in accordance with DE-GM 92 04 405.0 (file P 4910).
- roller press An essential feature of the roller press from which the invention is based is that the bearing blocks are coupled to one another in pairs by means of detachable tension rods. These tension rods are the only element for transferring the pressing force from the bearing block to the bearing block. Thus, the machine frames belonging to the roller press need only be dimensioned for the dead weight of the press units, but not for the transmission of the press force. It is also essential that the tension rods are easily detachable; they are therefore preferably biased to a fraction of the maximum pressing force at zero pressing force.
- these tension rods are movable or flexible in a sense, so that the bearing blocks of the "other pressing unit” are movable parallel to the pressing plane relative to the bearing blocks of the rigidly supported pressing unit.
- This is in contrast to the construction according to US 3,921,514.
- screw connections are provided which brace the bearing blocks with one another; This means that these screw connections must be pre-tensioned even when the roller press is not loaded.
- Screw connections are extremely voluminous and expensive in high-stress roller presses; assembling and Resolving can only be done with enormous effort.
- roller presses are preferably used in paper-making machines, the width of which in extreme cases can be up to 10.
- some roller presses are designed as shoe presses, in which the line force prevailing in the press nip can reach the order of magnitude of 1000 kN / m.
- an endless felt belt (used to dewater the paper web) has to run through the press nip and that such a felt belt has to be exchanged for a new felt belt at certain intervals.
- circumferential flexible (eg tubular) press element in shoe presses must be replaced from time to time.
- Such work can - thanks to the use of the easily detachable tension rods mentioned - be carried out in a relatively short time, so that the roller press is quickly operational again.
- a disadvantage of this proposed construction is that it is not possible to position the two bearing blocks precisely relative to one another, although guide jaws are provided on the machine frame.
- the main axis of the "other" press unit with the movable bearing blocks does not lie exactly in the press plane.
- the web is treated unevenly across its width and / or the roller jackets wear unevenly.
- the invention is therefore based on the object of further developing the roller press described in WO '641 in such a way that the main axis of the "other", ie the movable press unit, always remains as precisely as possible in the press plane during operation.
- This object is achieved by the combination of the features of claim 1.
- the tension rods - in the unloaded state of the roller press, i.e. with zero pressing force - are not pre-stressed as before or only to a fraction (eg 1/5) of the maximum pressing force.
- the bearing blocks of one press unit are rigidly supported on the machine frame, while the bearing blocks of the other press unit are movable along the press plane during operation.
- each of the Both rollers are mounted in a bearing block via a rotatable bearing journal.
- Each of the bearing blocks has two large flat guide surfaces on its outer sides, with which it can slide in the vertical direction on corresponding flat guide surfaces of a machine frame.
- the lower bracket rests on the machine frame, which has a threaded spindle with a vertical axis of rotation above the upper bracket.
- the threaded spindle engages the upper bracket to adjust the height of the roll gap; a spreading device presses the upper bracket against the spindle. Additional tension rods are unloaded in this operating state and especially during the rolling process. The rolling pressure is thus not transferred from the bearing block to the bearing block via the tension rods, but via the threaded spindle and via the
- Machine frame Compared to the subject of the application, there is a completely different type of machine. From time to time, it is intended to extend the two rollers together with the bearing blocks as a coherent assembly from the machine frame and to retract them (e.g. after a repair). In order to facilitate retraction, the outer guide surfaces of the two bearing blocks are held flush in that the bearing blocks have additional, directly contacting guide surfaces. This means that the pedestals are "centered" on one another - regardless of the machine frame. During the rolling process, however, it is not possible to keep the two rollers parallel to one another with the help of the additional guide surfaces alone. In this operating state, the mentioned outer guide surfaces, which interact with the machine frame, are indispensable.
- the following is characteristic of the construction according to the invention: on the bearing blocks alone or at least mainly such guide surfaces are provided which are independent of the machine frame. These guide surfaces are central in that area of the Roll press arranged, which (seen in the axial direction) is close to the press nip. During the normal operating state, in which the roller press is loaded and the tension rods are therefore under tension, the guide surfaces interact with the tension rods in such a way that the bearing blocks are held in the correct position with respect to one another with high accuracy. In other words, the transfer of the pressing force from the bearing block to the bearing block as well as the correct positioning of the "other" pressing unit (whose bearing blocks are movable) is completely independent of the machine frame.
- each bearing block has only a single guide surface.
- there is only a single pair of guide surfaces at each end of the roller press which is held in mutual contact by gravity, for example, by spring force (or with an inclined arrangement of the press plane). It is essential only that each movable bearing block of the adjacent rigidly supported by "a guide surface
- Bearing block is positioned so that its main axis is always in the press plane.
- two pairs of guide surfaces parallel to the pressing plane are provided at each end of the roller press.
- one bearing block can have a projection which engages in a recess in the other bearing block.
- a removable intermediate piece known per se is preferably provided between the two bearing blocks.
- this is now designed as a so-called guide piece; ie the side surfaces of the guaderiform guide piece parallel to the pressing plane are now guide surfaces; because the guide piece engages - similar to one between a shaft and a hub arranged key - fits snugly into the recesses of the two pedestals to ensure the correct position of the movable pedestals.
- the intermediate piece can be removed from the recesses, if necessary, for example for a change of felt.
- Fig. 1 is a view of an end face of the
- FIG. 2 is a longitudinal section along line II of FIG. 1.
- the roller press shown has an underlying first press roller 1 and an overhead second press roller 3.
- the axes of these press rollers lie in a press plane E.
- the first press roller 1 has a rotatable roller jacket la and a bearing journal 2 fastened to it, which by means of a
- Rolling bearing 2a rests in a bearing block 5 (with covers 5a and 5b).
- the bearing block 5 stands on a frame-shaped machine frame 15, of which some sections are indicated in FIGS. 1 and 2.
- the upper, second press roll 3 is a so-called extended-nip press roll.
- Your roller shell 3a is a tubular, flexible press jacket which is attached to two rotatable jacket support disks 3b. Each jacket support disk rests on the stationary bearing journal 4 of a stationary support body 4a, which extends through the interior of the roll jacket 3a.
- the support body 4a has a recess 4b relative to the lower press roll 1 and therein a piston-like and hydraulically actuated press shoe 4c. With its concave sliding surface, this presses the press casing 3a against the lower press roll 1, in order to thereby form an extended press nip (in the running direction).
- a paper web to be dewatered runs through this together with at least one endless felt belt F.
- the upper press roll 3 rests (at each roll end) with the bearing journal 4 likewise in a bearing block 6. Between the two bearing blocks 5 and 6 there is a removable one and on the bearing block 5 horizontal cuboid guide piece 9 is provided.
- the bearing block 6 of the upper press roller 3 rests on this when the roller press is in its unloaded state (ie when the recess 4b is depressurized). However, the loaded state is shown in which the press shoe 4c exerts a pressing force on the lower press roll 1.
- the resulting reaction forces are transmitted from the upper bearing block 6 to the lower bearing block 5 with the aid of flexible tension rods 7 and 8.
- the upper bracket 6 is lifted in this state by the distance p from the intermediate piece 9.
- a flexible tension rod 7, 8 is provided on both sides of the pressing plane E. These tension rods and U-shaped intermediate pieces 10, 11 are from the side in
- each of the flexible tension rods 7, 8 has a hammer head 20 at each end and is preferably designed in the manner of a leaf spring, the "leaf plane" of which is perpendicular to the pressing plane E. lies.
- the tension rods 7, 8 can deform when the support body 4, 4a is the second Press roll 3 experiences a (for example thermally induced) change in length and / or bends under the pressing force.
- the upper bearing block 6 can be rigidly connected to the bearing journal 4; the axial sliding surface between these two components required in an older construction and a spherical sleeve can be dispensed with.
- the invention can also be used if the axial sliding surface and the spherical sleeve are present, the tension rods not having to be flexible.
- the following is essential:
- a recess 25 is provided in the lower bearing block 5 according to FIG. 1, which has side surfaces parallel to the pressing plane E.
- a recess 26 is provided in the upper bearing block 6, which also has side surfaces parallel to the pressing plane E.
- the distances between the side surfaces mentioned are expediently the same in both recesses 25 and 26. Therefore, the cuboid intermediate piece 9 with its side faces 24, which are also parallel to the pressing plane E, fits into both
- Patent application (priority: DE P 41 40 879.9,
- the guide piece 9 can be removed; in this case it can be used together with the bearing block 5 form a one-piece component; in other words: it can form a nose formed on the bearing block 5.
- the guide piece is divided by a horizontal parting line into an upper and a lower section, for example only the lower section performing the guiding function and therefore engaging in both recesses 25 and 26. The height of the upper section can be adjusted using a spreading device.
- An axis of rotation 27 perpendicular to the pressing plane E is fixed in the upper bearing block 6.
- the head 28 of a threaded spindle 23 is rotatably mounted so that the axis of the threaded spindle is always in the pressing plane E (or at a short distance from it and parallel to it).
- the threaded spindle 23 extends into a bore 21 provided in the guide piece 9.
- a spindle nut 22 can come into contact with the guide piece 9 by turning on the spindle 23.
- the procedure is as follows: First, the upper press roller 3 is raised somewhat with the aid of an eyelet 12 and a hydraulic cylinder 16, which hangs on the machine frame 15, so that the spindle nut 22 is twisted open the spindle 23 can be released from the guide piece 9. Then the press roll is lowered until the bearing block 6 rests directly on the guide piece 9. Now the tension rods 7, 8 and intermediate pieces 10, 11 can be removed become. For example, the tension rod 8 is pushed onto a bolt 14 which is fastened to the machine frame 15. Now the upper press roll 3 is raised again with the help of the hydraulic cylinder 16. Thus, the guide piece 9 can now be swung out laterally upwards together with the spindle 23, as shown in FIG. 2 with dash-dotted lines. The guide piece 9 remains permanently connected to the spindle 23 with the aid of a small bolt 29 which extends transversely through the guide piece and the spindle.
- the spreading device consisting of the parts 22, 23, 27, 28 can also be arranged below the guide piece 9 in the bearing block 5, so that the guide piece is pivoted out laterally downward.
