Definitions
- the invention relates to a roller press, preferably for the treatment of a running web, e.g. B. paper web.
- the roller press comprises two Pressing units, e.g. B. press rolls, whose main axes in a press plane lie and together form a press nip through which the web runs.
- the roller press can also comprise three press units, the two Form press nips, or four press units, which form three press nips.
- the invention is based on a roller press having the preamble of claims 1 and 24 specified features.
- the "main axis" of a press unit can be, for example, the axis of rotation a press roll shell or the longitudinal axis of the stationary support body for example a shot press unit (in the latter case, the axis of rotation eccentric to the main axis).
- the "rotating press element” can be a metallic press roll shell, which is rotatable about a stationary support body and relative to it in radial Direction is displaceable, or a press belt or a tubular Press jacket, if it is a shoe press unit.
- the "internal pressure device” can be either a semi-ring Pressure chamber or a series of radially movable support elements or an elongated, radially movable press shoe.
- the “other press unit” can be above, to the side or below the rigidly supported press unit; their weight is determined by the Bearing blocks of the rigidly supported press unit worn.
- the expression “rigid supported” also includes the two-part pedestal construction Axial guide elements, e.g. B. according to DE-GM 92 04 405.0.
- An essential feature of the roller press according to the invention consists in that the bearing blocks in pairs by means of releasable tension rods are coupled together. These tension rods are the only element for Transfer the pressing force from the bearing block to the bearing block. So they need machine frames belonging to the roller press only for their own weight the pressing units, but not for the transfer of the pressing force to be dimensioned. It is also essential that the tension rods are easily detachable are; they are therefore preferably at most one at zero pressing force Biased fraction of the maximum pressing force.
- tension rods are movable or flexible in a sense that the bearing blocks of the "other press unit" relative to the bearing blocks of the rigidly supported press unit are movable parallel to the press plane.
- roller press From US 3,921,514 a roller press has become known in which screw connections are provided instead of easily detachable tension rods, which clamp the bearing blocks together; so they have to Bolted connections are strong even when the roller press is not loaded be biased.
- Screw connections are highly stressed Roller presses are extremely voluminous and expensive; assembling and Resolving can only be carried out with enormous effort. You have to be in this Take into account the context that such roller presses are preferred in Papermaking machines are used, the width of which in extreme cases can be up to 10 m.
- some roller presses are called Shoe presses formed, in which the line force prevailing in the press nip the Order of magnitude of 1000 kN / m.
- the press plane is vertical, i. H. the two press units one Such roller press are vertically one above the other.
- the two press units by means of one Lifting device (after removing the tension rods) in a simple manner vertically a little way from the other press unit will.
- the reassembly is just as easy afterwards Roller press; because during this work the main axis of the remains removing press unit always in the press plane.
- the invention is therefore based on the object Further develop roller press of the type mentioned in such a way that it too is easy to assemble with a non-vertically arranged press plane and the mentioned change work can be carried out as easily as possible.
- this object is achieved, inter alia, by that on the machine frame, foundation or the like, a support device is provided for (at least temporarily) a transverse to the Press-level component of the weight of the "other Press unit "is provided.
- a support device is provided for (at least temporarily) a transverse to the Press-level component of the weight of the "other Press unit "is provided.
- This The support device must be designed quite differently, depending on the individual Size of the angle between the press plane and the vertical direction.
- Numerous embodiments of the invention ensure that the Support device for guiding the other press unit in the Press plane serves parallel direction, so that the main axis of the other Press unit always remains in the press plane. This is done, for example realizes that a stationary part of the support device one to the press plane has at least approximately parallel guide surface.
- the support device is as trained pure force generator that generates a support force that the Counteracts weight force of the other pressing force.
- the support device according to the invention (provided for Inclusion of a component directed transversely to the press plane Weight of the other press unit) during normal operation of the Roll press not required.
- the cross component is named relatively small, so that they are on the tie rods on the bearing block the rigidly supported press unit can be transferred.
- the support device according to the invention is required in said case only during the assembly of the roller press or during the work to replace a felt or a Roll shell; because for this the tension rods must be removed and the the central guide surface is temporarily ineffective.
- the support device according to the invention is therefore required for temporarily removing the two from each other Press units. This is done in such a way that the Main axis of the other press unit completely (or at least approximately) remains in the press plane. Hence can - after moving the two back together Press units - the reinstallation of the removed components easily and quickly.
- bearing blocks of the other press unit rest immediately on guide surfaces parallel to the pressing plane.
- roller presses of the type described in the introduction with any inclination against the vertical Order direction are now possible.
- the rigidly supported press unit as Central roller trained.
- the roller shell of this The central roller usually comes into direct contact by train passing through the two (or three) Press nip runs.
- roller press according to the invention in the press section of a paper making machine and further details of the invention are set out below explained using the drawing.
- Fig. 1 shows schematically the rolls of a Press section.
- FIG. 2 shows schematically one deviating from FIG. 1 Press section and the associated machine frames.
- FIG. 3 is an enlarged detail from FIG. 1.
- FIG. 3A shows a tie rod (view in the direction of Arrow A of Fig. 3).
- FIG. 4 shows an enlarged detail from FIG. 2.
- FIGS 5 and 6 are schematic representations further embodiments of the invention.
- Fig. 1 shows a so-called split three-nip press section a paper making machine.
- Centerpiece is a central roller 2; this corresponds to that in claim 1 mentioned rigidly supported press unit.
- she has a smooth roll shell that is one side of the too draining paper web 9 touches. He forms with two Press units 1 and 3 a first press nip I and one second press nip II.
- the paper web 9 is in the usual Formed in a wire section.
- a support belt e.g. take-off felt 10
- a take-off suction roll 11 removed through a pre-press nip V led and then the first from below Press nip I supplied.
- the pre-nip V, the web 9 between the Take-off felt 10 and a bottom felt 15 happens formed by an overhead suction roll 16 and a lower press roll 17.
- the suction press roll 16 also has the Function of a deflection roller.
- the two press units 1 and 3 are designed as shoe press units. As is shown schematically in the shoe press unit 1, each shoe press unit has a stationary support body 18 and a flexible circumferential and liquid-tight press element 19. The latter is preferably designed as a tubular press jacket that is closed at both ends.
- the pressing element 19 is pressed onto the central roller 2 with a selectable pressing force by means of a pressing shoe 20 which has a concave sliding surface.
- the press nips I and II are therefore flat or "extended” press nips.
- the press shoe 20 rests in a recess 21 of the support body 18 designed as a pressure chamber. The pressure prevailing therein can be set between zero and a maximum in the usual way.
- the center planes of the shot press units 1 and 3 are so-called press planes E1 and E2.
- the take-off felt 10 must a relatively large sector u of the size of the Loop around the central roller (on both sides of press level E1).
- the position of the suction press roll 16 and (following the first press nip I) felt guide roller 22 certainly.
- Deviating from Fig. 1 in Fig. 2 is only the second Press nip II formed by a shoe press unit 3.
- First press nip I lies directly on the suction press roll 16 Central roller 2 on.
- the bottom felt 15 and lower press roll 17 (to form the pre-press nip V) provided or can be omitted, depending on the type of paper web to be produced.
- a roller bearing of the take-off felt 10 is schematically indicated multi-part machine frame 26 and another likewise multi-part Machine frame 27; this carries the central roller 2, the shoe press unit 3, the scraper 14, not shown (Fig. 1) and the guide rollers of the upper felt 23 and a take-off roller 13, via which a drying wire 12 a following (not shown dryer section) runs.
- FIG. 3 shows details of the three press units Roll press of Fig. 1.
- the bearing block 33 is on the bearing block 32 of the central roller 2 coupled with the aid of releasable tension rods 30, which are also called “tension rods" will.
- tension rods 30 are, for example (As shown in Fig. 3A) I-shaped. However, numerous other designs can also be used be applied; For example, the so-called divisible comes into consideration Traction spindle.
- the pressing planes E1 and E2 are arranged obliquely, as in FIG. 1, such that the first press nip is approximately in the 8 o'clock position and the second press nip is approximately in the 1 o'clock position.
- This configuration has the further advantage that the angle W between the two press planes is between 100 ° and 130 °, so that on the circumference of the bearing block 32 of the central roller 2 for both shot press units 1 and 3, the arms 52 necessary for coupling the tie rods 30 can be arranged. This would not be possible if the mentioned angle W were smaller.
- each movable bearing block 31, 33 is rigidly supported on a guide surface Bearing blocks 32 guided parallel to the press plane.
- the bearing block 32 has a nose 34, the side surfaces of which form fit in a recess 35 of the Bearing bracket 31 fits. Nose 34 and recess 35 thus form two pairs of guide surfaces parallel to the press plane E1 lie.
- Another possibility is between the bearing blocks 32 and 33 provided: There is a cuboid removable intermediate piece 36 with its side surfaces form-fitting in one recess each of the bearing blocks 32 and 33.
- the intermediate piece 36 thus also serves as Guide piece.
- Prestressing devices 37 shown by double arrows are provided, for example in the recess 35 between the bearing blocks 31 and 32 or between the intermediate piece 36, which rests on the bearing block 32, and the bearing block 33.
- the pretensioning device can, however, also outside of the recesses 35, for example on the tie rods 30 themselves to be ordered.
- the tie rods 30 are removed and installed, for example, with the aid of a Pneumatic cylinder 38, which is supported in the machine frame, with low compliance (not shown). Its piston rod 39 is like this dimensioned and stored so that they the weight of a tie rod 30th can carry.
- the pretensioning device 37 is made inactive; by means of the lifting device 42 becomes the bearing block 33 (with the complete press unit) drained by the distance p so that it rests on the intermediate piece 36.
- the bearing block 33 (with the complete press unit) raised again to the intermediate piece 36 to be able to remove. This lifting takes place so far that a certain Distance between the roll jackets of the pressing units 2 and 3 arises is necessary to change the felt or press jacket.
- the bearing block 33 of the shoe press unit 3 is over a tab 40 and a sliding block 41 coupled to the lifting device 42.
- the sliding block 41 can be on a guide surface 43 'parallel to the pressing plane E2 Support device 43 slide.
- Their position in Machine frame 27 is horizontal, for example Adjustable direction, as well as the point of application of the tab 40 on the bracket 33. This can be achieved that a Raise or lower the shoe press unit 3 in this way takes place that its central axis is always in the press plane E2 remains.
- the Lifting device 42 inactive so that the total weight of the Press unit 3 on the bearing blocks 32 of the central roller 2 rests. This is possible because of the angle between the Press plane E2 and the vertical direction relatively small is. If the lifting device 42 (for replacing the Felt or the press cover) is activated to the Press unit 3 to raise, then transfers Support device 43 directed transversely to the press plane E2 Component of the weight on the machine frame 27.
- the press plane E1 is arranged almost horizontally. At this arrangement it may be that the weight of the Shot press unit 1 is so large that it no longer has the Tension rods 30 can be transferred to the bracket 32.
- the press unit 1 rests (at each end) a (again adjustable) support device 46 which is also provided on the machine frame 26.
- a Lifting device 45 available to the or pushing the press unit.
- the support device 46 has again a guide surface parallel to the pressing plane E1 46 ', so that the main axis 1' of the press unit 1 is always in the press plane E1 remains.
- the centrally arranged Guide elements 34, 35 are therefore in some cases dispensable, as well as the spreader 37, if its Function can be exercised by the lifting device 45.
- one of the Shot press units 1 or 3 will be one end of the Press unit using a known (not shown) Press jacket retractor raised so that the Support device 46 or the tab 40 are removed can.
- Fig. 3 is also indicated schematically that the Central roller 2 is formed as a deflection adjustment roller is; therefore it has a stationary yoke 47.
- the inside of the roller is between the yoke 47 and the Roll shell a semi-ring-shaped and of Longitudinal sealing strips 48 limited pressure chamber 49.
- the position the sealing strip 48 is determined by the position of the Press planes E1 and E2 and by the amount of press forces. in the The result is the direction of action of the pressure chamber 49 the resultant of the pressing forces.
- Indicated schematically are two more (only at the drive end of the roller existing) bulges 50 of the bracket 32 for Recording drive pin 51, which in a known manner Serve drive the roll shell. These bulges must in that area of the circumference of the pedestal 32 may be arranged, which is free of the arms 52, in which engage the tie rods 30.
- the central roller 2 ' is again as Deflection adjustment roller formed, but now with a stationary yoke 47 'and a slide shoe 54 (or with a corresponding row of individual sliding shoes) in a known manner on the inner surface of the roll shell abuts and relative to the yoke 47 'parallel to the press plane E2 is mobile.
- the shoe press unit 3 is the same as in Fig. 3 formed; it rests on the pedestals during operation 32 'of the central roller 2'.
- the position of the press plane E1 is approximately the same as in Fig. 3.
- a hydraulic cylinder 56 is provided, in its pressure chamber the hydraulic pressure is always on one constant value is kept (by means of a Pressure control device 57). This value is across the board Press plane E1 directed component of the weight of the Press unit 1 adjustable. 5 is used Support device 56 thus only for transferring the mentioned weight force component on the machine frame 26, but not for guiding the press unit 1 parallel to Press level E1. For this there is a central pair of guide surfaces (at 35) provided on the bearing blocks 31, 32. Deviating 5, the hydraulic cylinder 56 could also be below the press unit 1 may be arranged.
- a press unit 1A hangs on the underside of the Bearing blocks 32A of a pressing unit 2A, by means of Tension rods 30.
- the bearing blocks 32A hang on vertical and / or horizontal surfaces of a machine frame 27A.
- the pressing plane E is only a small angle against the Vertical inclined. Therefore, the support device 66 be ineffective during normal operation, i.e. the Piston 67 of the single-acting hydraulic cylinder 68 can be pulled back down.
- Its axis 65 is parallel to the press plane E, so that the cylinder 68 also as The guide surface serves when the bearing blocks 31 A together with the pressing unit 1A (after removing the tension rods 30) A long way from the pressing unit 2A.
- a central removable Guide piece 36 between the bearing blocks 31A and 32A can in turn be provided (as with dash-dotted lines is indicated). You can also the guide piece 36 omitting. In the latter case there is another variation conceivable: one sees (instead of the shown Support device 66) a vertical-axis cylinder-piston unit by moving it horizontally on the Foundation 27B is adjustable.
