Definitions
- the invention relates to a machine for manufacturing a continuous web of material, in particular for the production of sanitary papers according to Preamble of claim 1.
- Machines of the type mentioned here have at least one drying cylinder to which the material web to be dried is guided around becomes.
- the drying cylinder is from the inside with help heated by steam, so that of a press section material web listed on the drying cylinder during the circulation on the lateral surface of the Drying cylinder is dried.
- the inner surface of the drying cylinder with circumferential grooves provided that are separated by ribs are.
- the material web is over at least one pressure roller listed on the drying cylinder, so that this is subjected to a pressing force. It has been found that the flexural strength the drying cylinder is not sufficient in many cases, especially not when high contact forces applied with a line force of> 90 kN / m will. Such high line forces are, however desirable to dry the web of material improve and thus the economy optimize the manufacturing machine. It has shown that with an increase in the jacket thickness the thermal resistance, the one Heat transfer from the steam to the one to be dried Material web opposes, not sufficiently lowered can be, so that relatively large drying cylinder diameter 5.5 m, for example are, at least when a high operating speed of, for example, 2000 m / min should be reached and exceeded.
- An embodiment of the machine is preferred, which is characterized in that the boundary walls at least one circumferential groove and / or at least one rib at an angle to each other, the circumferential groove widened radially outward while the rib radially outwards rejuvenated.
- Such a configuration is relative easy and inexpensive to manufacture and shows mentioned advantages regarding the bending stiffness and the thermal resistance.
- FIG. 1 shows a cross section through a part a machine 1 for producing a material web, whose dryer section 3 here is a drying cylinder includes.
- This has a cylinder jacket 7 and a hollow shaft 9, which in its end regions are connected to one another via a cover 11.
- the hollow shaft 9 is dashed illustrated pivot pin 13 continues to the appropriate Way held in a chair over a camp becomes.
- the bearing journal is hollow, so that the heating of the drying cylinder 5 serving Steam can be introduced into the interior 15 can.
- the steam gives its heat to the drying cylinder 5 or on its cylinder jacket 7 from, whereby condensate is formed, which turns on rotation of the cylinder, here clockwise (see the Arrow 17), precipitates on the inner surface 19.
- the Condensate can be removed using a condensate drain 21 be removed on the still closer is received.
- circumferential grooves 23 are introduced, that by intermediate ribs 25 from each other are separated.
- the circumferential grooves are spaced apart arranged, only hinted at here 27 introduced, which serve to be in to mix the condensate collecting the grooves.
- the material web 31 to be dried is guided.
- a pressure roller is used for this used, which is not shown in Figure 1, which will be discussed in more detail below.
- the material web 31 to be dried ie the sanitary Paper or crepe paper runs with it the rotating drying cylinder 5 um and will by the heat of the conducted into the interior 15 Superheated steam through the cylinder jacket 7 reaches the peripheral surface 29, heated and dried.
- the dried material web is on suitably from the peripheral surface 29 of the drying cylinder 5 removed.
- the condensate removal device 21 several, here six, so-called Cross collector 37 includes that via risers 39 connected to a central condensate drain line 41 are over the bearing pin 13 with a Condensate trap are connected.
- Receiving tubes 43 lead from the transverse collectors 37 to the bottom of the circumferential grooves 23.
- the number of Receiving tube 43 is ultimately freely selectable. It has proven itself, however, more than two suction tubes, for example three, four or as in figure 1 - to provide six, in particular in Connection with disruptive bodies a relatively even to achieve thick condensate film 61. A special one uniform heat transfer is then achieved if the receiving tubes 43 are adjacent Grooves on opposite sides of the Condensate discharge device 21 are arranged.
- condensate drainage devices arranged at the same circumferential distance from each other Recording tube 43 provided, each in one via a riser pipe 39 with the condensate drain line 41 connected cross collector 37 lead.
- the condensate is built up by the interior 15 Overpressure caused by the steam introduced arises, dissipated. It is possible with the condensate drain line 41 also a source of negative pressure to connect to quasi suck off the condensate.
- the drying cylinder rotates 5 arises solely due to gravity Flow within the condensate film, which is in the circumferential grooves 23 forms.
- an arrow 45 indicates that the condensate is at its lowest Low point of the drying cylinder 5 in the direction of Rotational movement flows while on the opposite topmost point of the drying cylinder 5 respectively the circumferential groove 23 an opposite forms a flow running in the direction of rotation, which is indicated by an arrow 47.
- the relative speed opposite the inner surface 19 or the bottom of the circumferential groove 23 is in the middle between the high and low point Zero.
- the boundary walls 51 of the circumferential grooves 23, the at the same time the boundary walls of the ribs 25 different sections show here: In The boundary walls run in the first upper region 51a parallel to each other and parallel to one standing perpendicular to the peripheral surface 29 imaginary center line 53. In a subsequent Area 51b runs under the boundary walls an angle ⁇ that is in a range of 5 ° to 90 ° can lie. In the embodiment shown here the angle is approx. 45 °. Becomes a Angle ⁇ 90 ° selected, so there are T-shaped circumferential grooves 23.
- the bottom one facing the bottom 49 Area 51c of the boundary walls 51 draws is characterized in that here the boundary walls again parallel to each other or to Center line 53 run.
- An angle is preferred ⁇ from 7.5 ° to 20 °, in particular from 10 ° to 15 °.
- a bluff body 55 is provided here, which condensate collecting in the circumferential grooves 23 builds up so that it is easier to remove and a condensate layer evenly thick over the circumference from approx. 1 mm to 3 mm.
- the Bluff body is here as essentially U-shaped Spring element formed, which due to its spring action claws to the area 51b.
- the length of the ones running here approximately vertically upwards Arms of the interfering body is adjusted so that these do not insert the receiving tube 43 hinder.
- the base of the disturbing body 55 is approximately like this wide as the width of the circumferential groove 23 in the area of reason 49.
- the condensate levels a transverse opening 57 introduced, the diameter of which is preferably 30% to 50% of the diameter of the receiving tube 43 is. It serves the after in the receiving tube to accelerate rising condensate.
- the under Overpressure in the interior 15 given steam penetrates namely through the transverse opening 57 into the receiving tube 43 and arrives via the cross collector 37 and via the riser pipe 39 into the condensate drain line 41.
- Straight in the vertical respectively radially extending area of the receiving tube this makes the condensate special easily dissipated, so that on the outer surface the drying cylinder 5 a very uniform Temperature distribution results.
- the receiving tubes 43 are to avoid a uneven temperature distribution in the cylinder jacket 7 in the circumferential direction and in the direction of extending perpendicular to the image plane of Figure 1
- the axis of rotation is distributed.
- Figure 2 also shows that in the circumferential grooves 23rd Interference body 27 can be introduced, as shown in FIG 1 already explained and essentially U-shaped can be trained.
- the bottom 49 after are upper legs of the disturbing body 27 longer than that of the bluff body and protrude into the Area 51a of the boundary surfaces 51 of the circumferential groove 23. You lean on one through the transition formed between the area 51 and 51b Edge 58 and are thereby on the circumferential groove captured.
- the cross collector 37 which is essentially about Width of the drying cylinder 5 extends with in the circumferential direction staggered tubes 43 is provided.
- the tube 43 ' to the right of the tube 43 is arranged further "rear", that is, further away from the viewer of FIG. 2 than that Recording tube 43.
- the receiving tubes 43, 43 ' By the inner surface 19 facing Boundary wall of the transverse collector and attached to this.
- the receiving tubes 43, 43 'via deflecting heads 38a, 38b to connect to the cross collector, for example to the across the width of the drying cylinder extending side walls 37a, 37b the cross collector 37 are attached and into which the Receiving tubes open and over which the receiving tubes connected to the inside of the transverse collector are.
- This way of attaching the tubes 43, 43 ' can be seen from FIG. 2a, the one Cross collector 37 in cross section.
- Figure 3 shows a longitudinal section through the circumferential groove 23 along the one shown in FIG Line III-III runs and thus a section the cylinder jacket shown in Figure 1 7 of the drying cylinder 5 reproduces.
- the representation is the cylinder radius assumed with infinity.
- the illustration in Figure 3 leaves the three areas 51a, 51b and 51c of the boundary surface 51 of the circumferential groove 23 clearly recognize.
- the representation according to Figure 3, the interference body 27 is partially in the Cut reproduced. Its base 59 is on the Bottom 49 of the circumferential groove 23.
- the one shown here Embodiment of the interfering body is quasi designed as a springy clip, the vertical thighs extending upward rejuvenate.
- the disruptive body 27 can with the help of a suitable tool into the circumferential groove 23 can be introduced, starting with the base 59 in Direction of the circumferential groove 23 extends.
- the width the base 59 is chosen so that this by the narrow region 51a of the circumferential groove 23 and can be applied to the bottom 49, wherein the two legs stand vertically upwards.
- Of the Interference body is then 90 ° into that shown in Figure 3 Position rotated so that the vertical upward running legs on the boundary walls 51 jam the circumferential groove 23 and hold the interfering body 27 securely.
- the thickness of the base 59 is chosen to be somewhat is greater than that by a line and triangles indicated condensate film 61.
- the rotation of the drying cylinder 5 runs Interference body 27 with the cylinder jacket 7 around, wherein at least the base 59 of the interfering body 27 in the Condensate film is located due to the relative speed opposite the bottom 49 of the circumferential groove 23 plowed through.
- the condensate becomes quasi mixed and turbulent to ensure that the heat of the interior 15 present Superheated steam to the bottom 49 respectively is transferred to the cylinder jacket 7.
- the means, the heat transfer from the interior 15 to Circumferential surface 29 is improved by the interference body.
- the interfering bodies explained with reference to FIGS. 1 to 3 27 can be designed as desired.
- Essential is that when the drying cylinder rotates remain in the circumferential grooves 23 and on act on the condensate film 61 by causing turbulence there cause and thus an even and ensure effective heat transfer.
- Based 4 shows a modified form of an interfering body 27 'explains that in a circumferential groove 23rd is introduced.
- Figure 4 only the bottom is Area of the boundary surface 51, namely the area 51c reproduced in which the interfering body 27 'is arranged.
- This is a coil spring, the main body of an imaginary Helix follows and an example shows rectangular cross section.
- the coil spring is square here.
- part of the machine 1 is again Production of a material web shown, namely the part of the dryer section 3 in which the still moist material web 31 on the drying cylinder 5 is listed.
- the representation chosen here is a partial section perpendicular to the axis of rotation of the Played drying cylinder from which the cylinder jacket 7 and a circumferential groove 23 can be seen are also a circumferential groove limiting Rib 25.
- the web of material 31 is applied on the peripheral surface 29 of the drying cylinder 5 from a conveyor belt 63, also referred to as felt supported, which over a circumferential press jacket 65 is performed.
- the press jacket 65 rotates in the opposite direction like the drying cylinder, so here counter clockwise. He is known to Way, from a stationary pressure shoe 67, of a suitable piston-cylinder arrangement 69 is supported on a stationary support 71, against the peripheral surface 29 of the drying cylinder 5 pressed.
- the one in the Interior 15 introduced hot steam gives its Heat to the turbulent, that is, from the interfering bodies mixed, condensate 61 and this conducts thanks to its high turbulence and convection the heat almost without resistance to the peripheral surface 49 further, so that the heat of the steam is close to the peripheral surface 29 is conveyed up. Also the protruding through the condensate film 61 into the interior Ribs 25 can absorb and absorb a lot of heat forward the peripheral surface 29.
- the machine 1 can therefore be operated with a very high power density be so that the drying cylinder 5 with be operated at a high peripheral speed can be in the range of 2,000 m / min and above can lie.
- the diameter of the drying cylinder that of conventional cylinders Art in the area of 5.5 m, also significantly reduced will. It is also crucial that in the by the pressure shoe 67 and the press jacket 65 press nip formed act high contact forces, because of which a very high moisture content can be pressed out of the material web 31, the then from the absorbent conveyor belt 63 respectively picked up in the felt and transported away can be.
- Figure 6 shows again a section of the cylinder jacket 7 of a drying cylinder 5 with a deviating cross-sectional shape of circumferential grooves 23 'is provided.
- the Boundary surfaces 51 of the circumferential groove 23 ' continuously quasi conical, that is, she close one opening radially outward An angle ⁇ in the range of about 5 ° can.
- the boundary surface 51 thus shows over here their entire height is uniform.
- FIG. 7 A slightly modified form of a circumferential groove 23 '' is shown in Figure 7. It can be seen that the boundary surface 51 in its upper, the area 51a facing the inner surface 19 Has boundary walls, which after the upper third of the circumferential groove in a conical Continue area 51'b. So this is missing Design of the circumferential groove 23 'of the FIG. 2 explained lower region 51c of the boundary wall 51, in which the boundary walls are parallel to each other.
- FIG. 8 schematically shows a circumferential groove 23 '' ', whose boundary surface 51 corresponds to that shown in FIG. 2 illustrated course shows, namely an upper area 51a, in which the boundary walls are parallel to each other run, a central region 51b, in which the boundary walls conically radially outwards diverge, and a lower radially outer Area 51c in which the boundary walls run parallel to one another and into the bottom 49 pass over.
- a tool 73 is indicated in FIG. partially retracted into the circumferential groove 23 '' ' is. The tool has a cutting edge 75 on the processing of the boundary surface 51st serves.
- the tool is shown as a dashed line Line is indicated in a first with a marked area parallel to the center line 53 lowered radially outward into the circumferential groove and then - deviating from the radial direction - when entering the circumferential groove further 23 '' 'laterally offset from the center line 53, around the conically diverging middle To produce area 51b of the circumferential groove 23 '.
- This range of movement is indicated by b in FIG. 8 featured.
- a last Movement range c the tool 73 exclusively in the radial direction, i.e. parallel to the center line 53 move, the boundary walls in the area 51c of the circumferential groove 23 '' '.
- the thermal resistance is thereby minimizes the hot steam from the interior 15 a relatively large area of the cylinder jacket can reach immediately because of the reason 49 of the circumferential grooves is relatively wide. Furthermore can from the relatively narrow, radially outer web the ribs 25 absorb heat from the interior and forwarded to the peripheral surface 29. Due to the increasing width from outside to inside the rib, which is preferably removed approximately T-shaped are trained, very high loads, when the material web is pressed on the circumferential surface are given safely intercepted will.
- the width of the grooves between the ribs in the area of the rib head is preferably 35% to 45% of the rib pitch and the width of the ribs is preferably 55% to 65% the division is.
- division is the distance from center to center of two adjacent circumferential grooves or ribs. For the rest, it must ensure that the ribs on the Base, i.e. at its radially outer end, are not too thin, otherwise they are not sufficient Strength is given. For this reason it is optimal ratio of groove width and division between the rib heads approx. 0.25 to 0.4 and at the Base approximately 0.45 to 0.7 of division respectively the distance from center groove to center groove.
- the radially outer extended area 51c of the Circumferential grooves is about 5 mm to 25 mm high.
- Prefers is a height of approx. 12 mm.
- the disturbing bodies 27 are preferred formed as U-shaped brackets, which are preferably consist of sheet metal.
- the one between the thighs lying middle section is approx. 5 mm to 12 mm wide (measured in the circumferential direction).
- the Thighs are either the same width or taper itself, as explained with reference to FIG. 3, up to the latter End to a width of 2 mm to 4 mm.
- the Sheet thickness is the condensate ring thickness respectively the height of the condensate film 61 adapted. she is approximately 1.2 to 1.4 times the thickness of the condensate depth.
- the width of the Interference body 27 is slightly less than that greatest width of the circumferential groove 23 in the area of Reason 49. This is the assembly of the interfering body relieved, that is, it is easily possible Interfering body in the circumferential groove or groove insert and by a 90 ° rotation around a radial axis to be clamped resiliently in the groove.
- the circumferential grooves and fins can ensure that heat transfer equally large due to the circumferential grooves or larger than through the ribs.
- the width of the circumferential grooves in the area of their Origin, i.e. in the area of the inner surface 19, is between 10 mm and 15 mm. It is chosen that the recording tube easily into the grooves can be introduced.
