Definitions

  • the present invention relates to steam-heated drying cylinder of a paper machine, the drying cylinder having a jacket, which on its inside has circumferential grooves for collecting condensate that is formed as a result of heat transfer through the jacket to the outside thereof.
  • the drying cylinder has a device for positioning a drain pipe of a draining system which is arranged in the steam-heated drying cylinder.
  • the draining system comprises an outlet means, which discharges on the outside of the drying cylinder, and a plurality of drain pipes which are arranged in a plurality of axial groups and connected to the outlet means, said draining system being adapted to remove the condensate from said grooves of the drying cylinder to the outside thereof via said plurality of drain pipes and outlet means, said device for positioning a drain pipe comprising a first pipe positioner which is disposed within an end portion of the drain pipe located closest to the jacket, said pipe positioner comprising a supporting body which is designed for resting on the top surfaces of two ridges located adjacent to each other, and a locking device for fixing the drain pipe to the pipe positioner, wherein the pipe positioner is provided with a first through hole for receiving the drain pipe, and a second hole for receiving the locking device, said second hole opening into the first hole.
  • a known positioning device has a pipe positioner with a transverse supporting body for abutting against two adjacent ridges, delimiting the jacket groove, and a carrying body which projects perpendicularly from the supporting body to be received in the groove. At its lower end portion, the carrying body is provided with a smooth through hole for receiving the drain pipe. A threaded hole extends from the top side of the supporting body downward therethrough and further through the carrying body all the way to the said smooth hole.
  • a locking device comprising a threaded rod, is screwed into the threaded hole for abutting against the drain pipe and locking it in the desired position for the drain pipe, said position being locked by means of a locking nut carried by the threaded rod.
  • the known pipe positioner thus having a T-shape, is made for use in a groove of a particular depth.
  • a different groove depth thus requires a T-shaped pipe positioner whose carrying body is shorter or longer in dependence on said groove depth, which is a problem particularly with respect to the stock-keeping of several sets of pipe positioners, where each set has its own, particular dimension.
  • US patent No. 4476637 discloses a steam heated dryer drum for drying of a web in a paper machine.
  • the dryer drum disclosed in that document has a shell with an inner surface that is grooved to create a series of collection channels for condensate which forms during operation and the grooves are separated by ribs.
  • Within the shell there are axially extending collectors and from the walls of each collector, small tubes extend in a tangential direction with respect to the shell. These tubes lead from the grooves to the interior of the collector.
  • a small guide plate At the free end of each tube is secured a small guide plate that may have a T-shaped form.
  • This guide plate is a tube positioning element and has a central lug with a hole therethrough into which projects the tube.
  • the lug has one laterally extending arm or a pair of laterally extending arms which rest on adjacent ribs. In this way, the free open end of each tube is held a predetermined distance from the bottom surface of the groove.
  • the object of the present invention is to achieve an improved positioning device for drain pipes which eliminates the above-mentioned problems, and which enables it to be used for all drying cylinder regardless of the depth of the grooves on the inside of the jacket. Thereby, the stock-keeping is reduced to only one set of the pipe positioner in question.
  • the positioning device is characterized in that said second hole opens into the first through hole and that a portion of the locking device that is located in the supporting body is provided with a third through hole adapted to interact with and be aligned with the first hole of the supporting body, so that the drain pipe extends through both the supporting body and the locking device, wherein the locking device is adapted to enclose the drain pipe and be brought to a locked position in interaction with the supporting body, in which locked position the drain pipe, the supporting body and the locking device are fixed to each other.
  • Figs. 1 and 2 show an interior section of a steam-heated drying cylinder 1, which is installed in a drying section of a paper machine for manufacturing a paper web.
  • the drying cylinder has a jacket 2, which has an outside, on which the paper web is dried, and an inside that is provided with a plurality of endless, circumferential grooves 3, evenly distributed in an axial direction, whose centres coincide with the centre axis of the drying cylinder 1.
  • the grooves 3 have a round, concave bottom surface 4.
  • the grooves 3 define ridges 5 between them, wherein the top surfaces 30 of the ridges 5 and the bottom surfaces 4 and lateral walls of the grooves 3 together form an inner jacket surface for heat transfer.
  • Such internally grooved drying cylinders 1 are used, inter alia, in the drying section of a tissue paper machine for manufacturing tissue paper, and then have a relatively large diameter which can vary from one machine to another. Furthermore, the drying cylinder 1 has a hollow central hub and two opposite axle journals, which are connected to the central hub to extend out through the opposite lateral end walls of the drying cylinder 1. The drying cylinder 1 is rotatably journalled by means of the axle journals, which thus define the axis of rotation of the drying cylinder 1.
  • the energy for drying the paper web is supplied in the form of steam to the interior space of the drying cylinder 1.
  • the steam condenses on the inner jacket surface, and the heat is conducted through the jacket 2 to its outside, with which the paper web is in contact.
  • condensate in the form of a film is accumulated on the bottom surface of each groove 3, said condensate film primarily determining the transition resistance from steam to jacket.
  • An efficient heat flow requires that the grooves 3 are kept as free as possible from condensate.
  • a special draining system for condensate comprising a plurality of elongated drain pipes 6 which commonly are called suction pipes and are arranged in a plurality of evenly distributed groups around the inside of the jacket 2, is used for draining each groove 3 from condensate as efficiently as possible.
  • the draining system comprises an outlet means which comprises, in order, a plurality of axially arranged collecting pipes 7, a stand pipe from each collecting pipe 7, a common centre connection for the stand pipes through said central hub and through one of the axle journals to the outside of the drying cylinder 1 for further transport. Accordingly, the number of collecting pipes 7 corresponds to the number of said groups.
  • the collecting pipes 7 are arranged eccentrically and axially relative to the centre axis of the drying cylinder 1.
  • Each drain pipe 6 has an end portion 9 having an open end 10, with which the space 11 of the groove 3 stands in open communication, and an end portion 12 having an open end 13 that opens into the collecting pipe 7, see Fig. 2 .
  • the opening 10 of the end portion 9 should be disposed at a predetermined distance from the bottom surface 4 of the groove 3, as is evident from Figs. 1 and 9 .
  • Each drain pipe 6 is provided with a device for positioning the drain pipe 6 relative to the inside of the jacket 2, and more precisely relative to the bottom surface 4 of the groove 3, in order to maintain said predetermined distance.
  • the positioning device comprises a first pipe positioner or pipe position adjuster 40, which is disposed in said end portion 9 of the drain pipe 6 that is located closest to the jacket 2.
  • the first pipe positioner 40 comprises a supporting body 41, which is designed for resting on the top surfaces 30 of two successive ridges 5 to extend in a direction transversely across the groove 3 located therebetween.
  • the supporting body 41 is delimited by two end surfaces 42, 43 facing away from each other, two lateral surfaces 44, 45 facing away from each other, an upper surface 46 and a lower surface 47, said lateral surfaces 44, 45 and upper and lower surfaces 46, 47 extending between said end surfaces 42, 43.
  • at least the lower surface 47 is curved as shown, e.g. circular-cylindrically.
  • a first imaginary plane extends through the end surfaces 42, 43 and the upper and lower surfaces 46, 47.
  • a second imaginary plane extends through the two end surfaces 42, 43 and the two lateral surfaces 44, 45 and intersects the said first plane at right angles.
  • the planes may define centre planes of the supporting body 41, but one of the planes, or both, may be located slightly to the side of said centre plane.
  • a first through hole 48 extends between the lateral surfaces 44, 45 and has a diameter that is slightly larger than the diameter of the drain pipe 6 for receiving the drain pipe 6 therein with a sliding fit, so that the supporting body 41 can be displaced along the drain pipe 6 to a desired position relative to the end 10 of the end portion 9 of the drain pipe 6, or alternatively said fulcrum of the drain pipe 6.
  • the first hole 48 has a centre axis that coincides with said second plane.
  • a second through hole 49 is adapted to extend between the upper surface 46 and the lower, curved surface 47, said second hole 49 having a larger diameter than the first hole 48.
  • the second hole 49 has a centre axis that coincides with said first plane.
  • the centre axes of the two holes 48, 49 intersect each other at right angles, and their common intersection point coincides with the intersection point of the two said planes.
  • the first pipe positioner 40 further comprises a multi-functional, elongated pin 50, which comprises a central portion 51 that is designed to be received in the said second hole 49 with a sliding fit, wherein the portion 51 thus has diameter that is slightly smaller than the diameter of the second hole 49.
  • the said portion is provided with a diametrical through hole 52, which has the same diameter as the first, smaller hole 48 of the supporting body 41 to thereby be aligned with the last-mentioned hole 48, so that the drain pipe 6 can be inserted into the smaller hole 48 of the supporting body 41 from one end and further through the hole 52 of the pin portion, and then further through the smaller hole 48 of the supporting body 4 and out through its other end.
  • the pin 50 comprises a lower guiding and supporting portion 53, which extends from the lower surface 47 to be received in the groove 3 with the purpose of guiding and supporting the pipe positioner 40 in the groove, so that the drain pipe 6 is maintained in the correct, aligned position.
  • the first pipe positioner 40 further comprises a locking device 54 for locking the three structural members 6, 41, 50 to each other.
  • a locking device 54 can be designed and arranged in a plurality of different ways. In the shown embodiment, it comprises a nut 55 and an upper, threaded portion 56 of the pin 50, projecting from the upper surface 46 of the supporting body 41, onto which threaded portion the nut 55 is screwed, to finally abut against the upper surface 46 of the supporting body 41 and be tightened so that the supporting body 41, the drain pipe 6 and the pin 50 are locked to each other.
  • the first pipe positioner 40 enables it to be used for all drying cylinders 1 regardless of the depth of the grooves 3 on the inside of the jacket 2.
  • it can be provided with recesses, on both sides of the hole 49 and extending downward a suitable distance in a direction from the upper surface 46, e.g. half of the distance down to the lower surface.
  • the device further comprises a second pipe positioner or pipe position adjuster 14, which is disposed in the end portion 12.
  • the second pipe positioner 14 comprises a mounting device 15, see Figs. 3 and 4 , for mounting the drain pipe 6 onto the collecting pipe 7, and a lockable connection 16 that connects the drain pipe 6 to the mounting device 15.
  • said connection 16 is a lockable joint connection which, in an unlocked condition, articulately connects the drain pipe 6 to the mounting device 15.
  • the joint connection 16 forms a fulcrum for pivoting of the drain pipe in at least one vertical plane, i.e. a plane coinciding with the centre plane of the groove 3 that intersects the centre axis of the drying cylinder 1 at right angles.
  • the joint connection 16 comprises an inner joint body 17, see Fig. 3 , which is permanently mounted, e.g. by means of welding, onto the drain pipe 6 at a predetermined distance from said open end 10 of the said end portion 9 of the drain pipe 6.
  • the inner joint body 17 is designed with a curved, outer joint surface 18, which comprises surface portions 19, 20 at least facing forward and backward, as seen in the longitudinal direction of the drain pipe 6 and in a direction toward the collecting pipe 7.
  • the joint connection 16 comprises an outer joint body 21, consisting of a first portion 22 and a second portion 23, see Figs. 3 and 4 , which are detachably connected to each other and which together enclose the inner joint body 17.
  • Each joint body portion 22, 23 is provided with an inner joint surface 24 and 25, respectively, see Fig. 4 , which has the same shape and same radius as the joint surface 18 of the inner joint body 17.
  • the two joint body portions 22, 23 are adapted to be joined into a unit, i.e.
  • the mounting device 15 and the joint body portion 22 located closest to the joint body 17 are made in one piece, as is evident from Figs. 3 and 4 .
  • the mounting device 15 and the outer joint body 21 have axially through-going centre holes 31, 32, see Fig. 4 , which have a larger diameter than the drain pipe 6 to thereby enable said pivoting of the drain pipe 6.
  • the lockable joint connection 16 it is constituted of a ball joint, wherein the said curved joint surfaces 18, 24, 25 are spherical, whereby the draining means becomes pivotable in all directions.
  • the mounting device 15 for mounting the drain pipe 6 onto the collecting pipe 7 comprises an externally threaded sleeve for screwing into an internally threaded hole 26 in a wall of the collecting pipe 7, said threaded hole connecting to the interior of the collecting pipe 7.
  • the centre axis of the hole 26 is directed toward the region of the groove 3, where the drain pipe 6 is to suck condensate.
  • a screw depth stop 27 is formed at the transition to the ball joint 16.
  • the first joint member portion 22 is cylindrical and has an external thread.
  • this first joint body portion 22 and said sleeve 15 are designed in one piece, wherein said screw stop 27 is formed by a radial, circumferential surface at the transition therebetween in that the first joint body portion 22 has a larger diameter than the sleeve 15.
  • the second joint body portion 23 has the shape of a nut, having an internal thread and a diameter at this thread portion which are adapted to the outer diameter of the first joint body portion 22 and its thread, so that the nut 23 can be screwed onto the first joint body portion 22 for the formation of screw connection while enclosing the inner spherical joint body 17.
  • the side of the nut 23 facing away from the thread portion has a wall 28 that is provided with a centre hole 29, through which the drain pipe 6 extends and which also allows that a small portion of the inner, spherical joint body 17 can project therefrom to thereby enable that the drain pipe 6 can be pivoted in the desired way, when the ball joint is in a loosened state.
  • the reference numeral 36 designates a securing plate, which is carried by the sleeve 15 and is foldable down over the nut 23 so that it is locked against being loosened, as is evident from Figs. 1-4 .
  • a device with a second pipe positioner where the end portion of the drain pipe facing toward the outlet means, and more precisely toward a collecting pipe, is provided with an external thread for screwing the drain pipe into the mounting device, which has a corresponding internal thread. Furthermore, the threaded portion of the drain pipe carries a locking nut, which is adapted to be brought into locking abutment against the mounting device, when the position of the drain pipe relative to the bottom surface of the groove has been decided. The position of the drain pipe relative to the bottom surface of the groove is thus set and adjusted by a rotation of the drain pipe about its axis so that it is screwed into or out of the mounting device.
  • a disadvantage of the known device is that the length of the drain pipe is adapted to a particular drying cylinder and its diameter. Therefore, a range of drain pipes has to be provided for each size of drying cylinder, with respect to their diameters.
  • Another disadvantage is that the mounting of the drain pipe is inconvenient and time-consuming in that it has to be performed directly inside the drying cylinder, and, furthermore, in that the adjustment of the drain pipes has to be done one by one without being able to utilize the settings of a previous, already mounted drain pipe.
  • the second pipe positioner 14 included in a preferred embodiment of the device according to the invention, enables one and the same length of the drain pipe 6 to be used for drying cylinders 1 having different diameters in that the second pipe positioner 14 is pivoted relative to the mounting axis 33, see Fig. 3 , which is defined by the mounting device 15 that is fixed to the collecting pipe 7, so that the centre axis 34 of the drain pipe 6, see Fig. 3 , forms an obtuse angle with the mounting axis 33, wherein the centre axis 34 thus may extend downward, as is shown in Fig. 3 , or upward relative to the fixed mounting axis 33. In both cases, the centre axis 34 forms an acute angle ⁇ , see Fig.
  • the mounting of the drain pipes 6 can be performed in a faster, simpler and more convenient way in that it is only necessary to mount a first drain pipe 6 onto the collecting pipe 7, and thereby to set a desired angle, which is fixed by the nut 23 of the ball joint 16, whereafter the mounting device 15 is once again detached from the collecting pipe 7 to be used as a template for setting the corresponding angle of the other drain pipes 6 of the collecting pipe 7, which operation consequently can be carried out outside of the drying cylinder 1, whereafter the thus pre-positioned drain pipes 6 with associated devices can be mounted onto the collecting pipe 7 inside the drying cylinder 1.
  • the fulcrum of the drain pipe 6 is thus defined by the centre point of the spherical joint surface 18 of the ball joint 16.
  • the joint surface is cylindrical, defining a horizontal centre axis, which thus constitutes the fulcrum of the drain pipe 6.
  • the first pipe positioner can be used in combination with any type of the second pipe positioner, e.g. the known design which has been described above, where the end portion of the drain pipe facing toward the outlet means, and more precisely toward a collecting pipe, is provided with an external thread for screwing the drain pipe into the mounting device, which has a corresponding internal thread, or the new design, described more closely above, having a pivotable mounting of the drain pipe, which is preferred due to its many advantages over the said known design.
  • the second pipe positioner e.g. the known design which has been described above, where the end portion of the drain pipe facing toward the outlet means, and more precisely toward a collecting pipe, is provided with an external thread for screwing the drain pipe into the mounting device, which has a corresponding internal thread, or the new design, described more closely above, having a pivotable mounting of the drain pipe, which is preferred due to its many advantages over the said known design.
