Date May 11, 1983.A size press, which comprises three coating rolls (11, 12, 13). These rolls (11, 12, 13) form two press nips (N1, N2) as pairs with each other, the paper web (W) to be treated being passed through the said press nips. Both sides of the web (W) are treated in the said nips (N1, N2). Out of the said coating rolls, regarding the position of altitude, the uppermost roll (12) has been arranged as the center roll of the size press, in connection with which center roll the two coating nips (N1, N2) are formed so that the first coating nip (N1) is placed at a short angular distance ( alpha 1) underneath the horizontal plane (H-H) placed through the axis of the said center roll (12). The second coating nip (N2) is formed by the third coating roll (13), which is placed substantially in the vertical plane (V-V) placed through the center point of the center roll (12) or at a small angle ( alpha 2) after the said plane. As preceding the first nip (N1), size-feed devices (24, 25) have been provided at the center-roll (12) side of the run of the web (W), which size-feed devices (24, 25) feed a first size pool (L1) or layer into the substantially vertical pit between the center roll (12) and the web (W). Preceding the second nip (N2), a second set of size-feed devices (26, 27) has been provided in the substantially horizontal pit formed by the center roll (12) and by the third coating roll (13), the said second size-feed devices (26, 27) forming the second size pool (L2) or layer at the opposite side of the web (W), as compared with the said first size pool (L1) or layer. The said devices are jointly operative so that, while the sizing is performed, the web (W) is supported by a roll face. 公开号:SU1369679A3 申请号:SU833610401 申请日:1983-06-23 公开日:1988-01-23 发明作者:Коски Эркки 申请人:Валмет Ой (Фирма); IPC主号:
专利说明:
51 l | t SO O5 with a with cm Rc & 1 This invention relates to the pulp and paper industry, in particular to the size sizing presses of a paper making machine. The purpose of the invention is to provide a higher speed of movement of the paper web due to the less curved path of its passage. FIG. 1 shows gluing. press, general view; in fig. 2 - the same, side view; in fig. 3 - section aa and n of fig. 2; in fig. 4 is a view B in FIG. 2 The size press contains frame 1, on which, with the possibility of rotation, rollers 2-5 are mounted and other devices are fixed. The entrance of the web W intended for processing and exiting the paper machine is indicated in the size press as W,. The output of the web W, processed on both sides of the covering agent, for example, glue from the sizing press is designated Wp. The stroke of the web W intended for processing, through the size press is indicated by a broken line. On the base there is a size press 6. The protective sheets 7 prevent the glue from splashing. Outside from the size press rollers in the direction of the web W, there is a first guide roller 2, which is rotatably connected to the frame 8 and mounted so as to move in the direction of the arrows F along the guides 9. The first roller 3 for applying the coating so that it can rotate mounted on supports U, which are fixedly attached to frame 1 by means of a horizontal articulated shaft 11. The frame can be turned by a biaphragm actuator 12, by means of which adjust the pressure line of the first pressurized n coating zone N. The first N-pressurized coating zone is formed by rollers 3 and 4 for coating. The roller 4 is a central roller of a press which is attached to stationary bearing supports 13. The central roller 4 forms a second N-pressable coating zone with the third lowest roller 5 for coating. Third movie 5 d Q 5 o 0 five five five for coating, it is attached to supporting supports 14, which are fixedly connected to frame structures 15. The frame structures 15 are connected to the frame 1 by means of horizontal articulated shafts 16, so as to be able to rotate by means of a diaphragm drive mechanism 17, for example, to adjust the pressure of the pressing zone in the second pressurizing zone N. Two pools L and Lj with an agent intended for coating are formed in the device. Devices for supplying an agent intended for coating, located together with the first pool L, contain a conduit 18 for supplying glue extending across the entire width of the web W and provided with several conduits 19 with nozzles adjacent to each other or a corresponding single slotted nozzle . The first pool, with glue, is made in the gap formed by the central roller 4 and the web W to the first pressing zone. From the basin L, the glue or some other suitable coating agent is absorbed on one side of the web W and the adhesive agent in the pressing zone N is pressed into the web W. I The device comprises a second conduit 20 for supplying glue, mounted close to the third roller 5 for applying the coating practically at the level of the pressing zone N, and together with the pipeline 20 there is a series of nozzles 21 for supplying the adhesive or a corresponding slit nozzle. The nozzles 21 supply streams of glue to a separate chute 22 of the second pool L, with glue located in front of the pressing zone N. Thus, the second pool L. with glue is formed upstream of the pressing zone NJ and from this pool L is processed and pressed onto the other side of the web W. pressing zone N a web W, for example, follows roller 4 into sector oi, followed by web W passes through guide rollers or something equivalent to subsequent processing steps, in this particular case, to the upper cylinder of the drying section (not shown) . The gl sector may be smaller or larger, so that the passage of the web W after the size press is also smooth. The web W is in contact with the first roller 3 for coating at an appropriate angle of before the pressing area N, which is also important in terms of the fact that an attempt is made to prevent air from entering the pressing area N,. 40 °. On the free sectors of the rollers 3-5 for coating made mouth Thus, the geometry of the sizing press rollers is such that the uppermost roller 4 is the center roller, and the peripheral rollers 3 and 5 are arranged so that the first pressing area N is formed slightly below the horizontal LV plane (angle o / and size N., Fig. 1), and the second pressing zone N is formed, in fact, in the vertical plane YY or somewhat beyond this plane (angle o,). This size press also has Properties that contain surfaces are the role of an advantage. cleaned of covering agent, and from these devices only the scraper 23 of roller 4 is shown. Essential is the arrangement of the rollers 3-5 relative to each other to form the N extrusion zones, and That a conventional known vertical press with one pressing zone can be usefully converted to the size press according to the invention by means of supplying it with another peripheral roller 3 and devices 2 and 25 for feeding glue belonging to the first pool L with glue. N as well as pools L, and L. with Klel l d 1 aix / n- - v о, h. V ri 11 and f t Next to the extrusion zones N and N, and their location relative to the rollers 3-5 and the web stroke W. The central roller 4 (Figs. 1 and 2) of the size press is the uppermost roller of the press, so that the first pressing zone N between the peripheral press the roller and the central roller 4 are formed under the horizontal plane of the NN passing through the center point of the central roller 4 (distance H) at the central angle o /, of the roller. Angle 0 is a relatively small angle, the magnitude of which is in the range of 5 to 20 °, usually the most preferred value is of the order of 10 °. In any case, the angle o / is less than 45 °. The other peripheral roller 5 is located under the central roller 4, most preferably after the vertical plane YY passing through the central point of the roller 4 under a small center. angle of rotation for example from The magnitude of the angle (At 5Сос- 5 to 10. Thus, the central roller is the uppermost roller among the said rollers, being located at a distance H higher than the first peripheral roller 3 to which the web W is fed. Because the angle is small, the vertical distance between the central points of the rollers 4 and 5 is H, {+ RH. five That a conventional known vertical press with one press zone can be usefully converted to the size press according to the invention by supplying it with another peripheral roller 3 and devices 24 and 25 for supplying glue related to the first pool L with glue. In addition to the additional details of the feeder and pool L one L, with glue, then in relation to the pool Lj with glue to blowing to make a specific reference to figure 2, according to which the pool with glue is formed by a box girder. Together with the beam, there is a pipe 20 for supplying glue and pipes 21 with nozzles that supply glue to the pool. The gap between the beam and roller 5 is sealed by means of elastic cable 26, the inner edge of which is in contact with roller 5. Sealing juice 26 is fixedly attached to the beam by holder 27. The pool with glue is formed in the transverse direction by walls 28, under which there are gutters 29. At the lower end of the gutter 29, there is a pipe 30 through which any excess glue can flow into the exhaust lines 31. The corresponding gutters 32 are arranged at the sides of the first pool L, with glue and the first pressing zone N. Supply of glue to the supply pipe above the first pool L with glue is indicated by an arrow, and the supply of glue to the gluing line 20 connected to the second pool L is indicated by the arrow Lfn. It is known from experience that it is advantageous to have a hard roller and a soft roller against each other, since in the pressing zone between the two hard rollers there is a tendency to form holes in the paper. In a preferred embodiment of the invention, the hardest roller is a central roller 4, for example a micro-coated roller, whose hardness is in the range from 0 to 1 Pousse hardness. According to said first pool L, with glue is actually a vertical pool formed in a vertical groove between rollers 3 and 4. Cloth W, passing for the purpose of treatment in the pool zone L, To jones With this roller 4, the first zone is held by the surface of the first peripheral roller 3. The second pool L with glue is a side pool that precedes the second pressing zone N, located actually in the vertical plane YY. Pool L must be compacted by ska 26 or something equivalent to it relative to the second peripheral roller 5. In the area pressing N is formed by a roller with a softer Micromeet coating, the surface hardness of which is, for example, in the range from 20 to 30 according to Puss-Jones. The second pressing zone ig Nj with the central roller 4 is formed by a second peripheral roller 5, the surface of which is similar to the surface of the roller 3. With the described arrangement of the rollers Q of the second pool L ,, the web W retains the initial requirement for the hard roller and the soft roller to form a gap, is fulfilled by the fact that the central roller 4 is the hardest roller and two softer rollers 3 and 5 are pressed against the central roller. The moisture content of the paper web included in the size press is from 3 to 8%. When moisture is less than this, the paper becomes brittle and its ability to absorb, deteriorates. With more moisture than this, the moisture content becomes heterogeneous and the paper's ability to absorb is very high. The load in the N and N extrusion zones is from 10 to 50 kN / m, preferably in the order of 30 to 40 kN / m. At least one of the two rollers of the 3-rollers should be rollers with a variable crown part, especially in the sizing presses, by means of which various types of paper are fed. A changeable crown part is more necessary for wide machines than for narrow ones. It is most acceptable when the diameters 2R ,, 2R and 2Rj of the rollers 3-5 are chosen to be equal to each other in order, for example, to facilitate maintenance work. In each N and N extrusion zone, one of the rollers must also be soft, for the reason that the extrusion in N and N zones must be sufficiently wide. Each of the rollers 3-5 has its own adjustable drive 33-35. The peripheral speeds of the rollers are equal to the belt speed. According to this, the first basin L, with glue, is in fact a vertical basin formed in a vertical recess between rollers 3 and 4. The web W extends for processing in the basin zone L, held by the surface of the first peripheral roller 3. The second pool L with glue is a lateral pool that precedes the second pressing zone N, located essentially in the vertical plane YY. Pool L must be compacted by ska 26 or something equivalent to it relative to the second peripheral roller 5. In the area five 0 five 0 five 0 five
