Definitions

  • the invention relates to a sealing device for sealing an overpressure or underpressure zone according to the preamble of claim 1, a roller for a machine for producing or processing a fibrous web according to the preamble of claim 6, and a method for operating a roller according to the preamble of claim 7 or 8.
  • Sealing devices in vacuumed or blown rolls for paper, cardboard or tissue machines must reliably seal the overpressure or underpressure zone against the environment in which normal pressure prevails.
  • the sealing surface of each sealing strip of the sealing device is positioned against the inside of the rotating roller jacket.
  • an attempt is made to introduce a lubricant between the sealing surface and the inside. This is usually done with spray pipes, which are arranged in the direction of rotation of the roller in front of the first sealing strip of the overpressure or underpressure zone.
  • the lubricant is applied to the inside of the roller shell and transported by the latter to the individual sealing strips through its rotation, as a result of which, viewed in the direction of rotation, the lubricant supply decreases from sealing strip to sealing strip.
  • a large amount of lubricant must be used, but this only benefits the actual lubrication of the sealing strips to a small extent and otherwise contributes to the undesired rewetting of the fiber web.
  • a preferred embodiment of this invention also proposes a lubricant channel provided on the top of the roller in the form of a groove-like depression arranged next to the sealing surface and extending in the longitudinal direction of the sealing strip, ie in the cross-machine direction of the roller, possibly with the aid of a suitable lip.
  • a further object of the invention is to provide a reliable method for operating such a roller using a small amount of lubricant.
  • a sealing device for sealing an overpressure or underpressure zone of a roller for a machine for producing or processing a fibrous web according to the characterizing part of claim 1 and a roller for a machine for producing or processing a fibrous web according to the characteristic Part of claim 6 and, with regard to the method, by a method for operating a roller according to the characterization of claims 7 and 8, respectively.
  • a sealing device for sealing an overpressure or underpressure zone of a roller for a machine for producing or processing a fibrous web
  • the sealing device having a sealing strip and a lubricating device by means of which, when used as intended, a lubricant is placed between the inside of the roller shell and the sealing surface the sealing strip can be brought
  • the lubricating device comprises a plurality of lubricant outlet openings and can be connected to a supply line for supplying lubricant.
  • the lubrication device can be connected to the supply line via several inlets, which are distributed over the length of the sealing strip, the sealing strip has a first and a second longitudinal end and the distance from at least one, preferably both longitudinal ends to an inlet is a maximum of 1000mm, specifically a maximum of 800mm, in particular a maximum of 600mm, preferably 400mm or less.
  • Such a sealing device can be particularly advantageous in order to also supply the edges of the sealing strip with sufficient and uniform lubricant.
  • each point can be supplied with lubricant from both the right and the left, since there is at least one inlet on both sides through which the lubricant is supplied to the lubricating device.
  • the problem arises that these areas are only supplied with lubricant from one side, since there is an inlet on only one side. This can lead to the region of the longitudinal ends of the sealing strip not being supplied with sufficient lubricant, especially with less lubricant than the central area of the sealing strip.
  • the inlets are arranged such that their distance from one another in the longitudinal direction of the roller is less than 2 m, in particular less than 1.75 m, preferably 1.5 m or less.
  • the inlets can also be arranged in such a way that the distance between adjacent inlets is the same in the longitudinal direction of the roller or does not deviate from one another by more than 500 mm.
  • the lubrication device can preferably be provided entirely or partially in or on the sealing strip, it being possible in particular for the lubricant outlet openings to be in the sealing strip.
  • the distance from at least one, preferably both, longitudinal ends to an inlet is at least 20 mm, in particular at least 50 mm.
  • a distance of 100mm can also be advantageous. If an inlet is located too close to the longitudinal end of the sealing strip, the effect can occur that the supplied lubricant either passes over the end of the sealing strip. To prevent this, the effective width of this inlet can be kept small by reducing the supply of lubricant. However, this means that a further inlet must be provided relatively close to this first inlet.
  • the lubrication device is provided entirely or partially in or on the sealing strip, and in particular the inlets are provided in the sealing strip. In this way, no inlets have to be provided in the sealing strip holder in particular.
  • roller which comprises at least one sealing device according to one aspect of the invention.
  • water can usually be used, to which additives can optionally be added.
  • the pressure in the The supply line can be between 2 and 8 bar, in particular 3 to 6 bar, for example.
  • a sealing device for a machine for producing or processing a fibrous web, which has a movable roll shell and an over- or negative pressure zone, as well as a sealing device for sealing the positive or negative pressure zone from the environment.
  • the sealing device has a sealing strip and a lubricating device, by means of which a lubricant can be brought between the inside of the roller shell and the sealing surface of the sealing strip, the lubricating device comprising a plurality of lubricant outlet openings and connected via several inlet segments to a supply line for supplying lubricant is.
  • the roller is characterized in that the supply line comprises an inner section which runs inside the roller jacket and this inner section has a storage volume of at least 500 cm 3 / m, in particular of at least 750 cm 3 / m or 1000 cm 3 / m, based on has the length of the sealing strip.
  • An inlet segment should be understood to mean a line part which is connected to the supply line which supplies the entire lubrication device and which conducts lubricant to part of the lubricant outlet openings.
  • the sealing device of this roller can be designed as a sealing device according to one aspect of the invention.
  • the inlet segments can be connected to the inlets of the sealing device.
  • the size of the storage volume should be at least 500 cm 3 / m.
  • the value of 500 cm 3 / m is sufficient for the commonly used quantities of lubricant from 0.5 l / m / min to approx. 3 l / m / min.
  • Larger storage volumes of 1000 cm 3 / m, 2000 cm 3 / m or more are advantageous for reasons of equalizing the pressure, as described above. Due to the very tight installation space in some rollers or also for economic reasons, it can make sense to limit the size of the storage volume upwards. It can therefore be advantageous not to provide the storage volume greater than 20,000 cm 3 / m or 10,000 cm 3 / m.
  • the specification of the storage volume in "cm 3 / m" relates to the length of the lubricated sealing strip.
  • the roller can advantageously be designed as a suction roller.
  • the roll shell has openings which are usually arranged in the form of a regular pattern.
  • water can be sucked out of a fibrous web or a covering through the openings in the roll shell.
  • a pipe that has an inside diameter of 25mm over its entire length already provides more than 500 cm 3 / m of storage volume, for example.
  • the tube tapers continuously over its length.
  • Such a design can be advantageous in particular in the case of long sealing strips with more than 5 m or more than 10 m in order to keep the pressure at the inlet segments at the rear in the direction of flow of the lubricant constant even further.
  • the majority of the lubricant outlet openings are evenly distributed over the length of the sealing strip, in particular that the distances between adjacent lubricant outlet openings differ by less than 25%.
  • a distribution of the lubricant outlet openings also supports the uniform distribution of the lubricant over the entire length of the sealing strip.
  • the distance between two adjacent lubricant outlet openings can advantageously be between 20 mm and 200 mm, in particular between 30 mm and 100 mm. In particularly preferred embodiments, the distance between adjacent lubricant outlet openings is between 40 mm and 60 mm.
  • the inlet segments are arranged such that their distance from one another in the longitudinal direction of the roller is less than 2 m, in particular less than 1.75 m, preferably 1.5 m or less.
  • the inlet segments can also be arranged such that the distance between adjacent inlet segments is the same in the longitudinal direction of the roller.
  • the lubrication device can be implemented, for example, in that the lubricant is fed from the inlet segments to nozzle devices, e.g. fan nozzles, which represent the lubricant outlet openings.
  • the lubricant is lubricated via the nozzles in the direction of the sealing surface to be lubricated.
  • These nozzle devices are known as lubrication spray pipes and are usually arranged in the direction of rotation of the roller in front of the sealing strip.
  • the lubricating device can also be advantageous for the lubricating device to be provided entirely or partially in or on the sealing strip, with the lubricant outlet openings in particular being located in the sealing strip.
  • Such sealing strips with an integrated lubricating device are often preferred because the sealing surface can be lubricated with a smaller amount of lubricant.
  • Sealing devices often have a so-called holder for receiving the sealing strip.
  • the inner section runs at least partially on or in this holder.
  • all inlet segments have the same length or differ in length by less than 25%. If the differences in the lengths of the inlet segments are too great, there may be a risk that the effect of equalizing the pressure cannot be fully passed on to the lubricant outlet openings.
  • the length of the inlet segments can advantageously be between 150 mm and 700 mm, in particular between 200 mm and 400 mm.
  • the inner section of the supply line is mounted on the outside of the suction box of a negative pressure zone.
  • this mounting position is easier to access than inside the suction box.
  • the distance from the inner section of the supply line to the inlets of the sealing strip is usually smaller, so that one can get by with shorter inlet segments with a length of 150mm-250mm, for example.
  • the distance between an inlet segment and a longitudinal end of the sealing strip can preferably be a maximum of 1000 mm or a maximum of 800 mm, in particular a maximum of 600 mm, preferably 400 mm or less.
  • the supply line also has an outer section which runs essentially outside of the roller, the outer section having an inner diameter of 25 mm or less, in particular 20 mm or less or 15 mm or less over an end face Inside the roller is guided, where it is connected to the inner section.
  • the outer section can have a smaller inner diameter than the inner section, in particular also at the junction of the two sections.
  • the object is achieved by a method for operating a roller for a machine for producing or processing a fibrous web, the roller being designed according to one aspect of the invention, characterized in that the lubricating device operates at less than 2.4 l / min / m , in particular between 0.4 l / min / m and 1.5 l / min / m of lubricant is supplied. With such an amount of lubricant, the roller proves to be particularly advantageous according to one of the above-mentioned aspects.
  • the lubrication device is supplied with 2.4 l / min / m or more of lubricant over a start period, and after this start period the amount of lubricant increases to less than 2.4 l / min / m, in particular between 0.4 l / min / m and 1.5 l / min / m is reduced.
  • a start period can be, for example, at least 30 seconds, in particular between 30 seconds and 5 minutes.
  • Such a start period, which precedes the standard operation can ensure, among other things, that the storage volume is completely filled with lubricant and thus the roller or the lubricating device can develop its full effect. This is particularly advantageous in the case of rollers in which an inner section of the supply line has a storage volume which, as indicated in the further idea, is at least 500 cm 3 / m.
  • a supply line 6 which comprises an inner section 7 which runs inside the roll shell 11 and a storage volume of at least 500 cm 3 / m, in particular of at least 2000 cm 3 / m, based on the length of the sealing strip, and an outer section 8.
  • the lubricating device 4 is connected to the inner section 7 of the supply line 6 at a plurality of inlets 10, 10a via a plurality of inlet segments 9, 9a.
  • the distances between two adjacent inlet segments 9, 9a and / or two adjacent inlets 10, 10a can each be the same.
  • the inlet segments 9, 9a are arranged such that their distance from one another in the longitudinal direction of the roller 1 is less than 2 m, in particular less than 1.75 m, preferably 1.5 m or less.
  • the distance from an inlet segment 9a or an inlet 10a to a longitudinal end of the sealing strip 3 can preferably be a maximum of 800 mm, in particular a maximum of 600 mm, preferably 400 mm or less.
  • the inner section 7 of the supply line consists of Figure 1 from a tubular part.
  • This tube can advantageously be made of a material (for example metal or plastic) that is more rigid than the inlet segments 9, 9a.
  • a material for example metal or plastic
  • pipes with an internal diameter of 25mm corresponds to a storage volume of approx. 500 cm 3 / m
  • 40mm or 50mm corresponds to a storage volume of approx. 2000 cm 3 / m
  • the inlet segments 9, 9a can be designed as hose segments, for example.
  • Figure 2 differs from Figure 1 in that the inner section 7 consists of a tube 7 which tapers continuously over its length.
  • Figure 3 shows a sealing strip 3 in a holder 3 a, which is pressed against the inside of the roll shell 11 of the roll 1 by means of a pressure hose 13.
  • a pressure hose 13 for pressing against a moving surface such as a roll shell is a common measure known to those skilled in the art.
  • the lubrication device 4 is not integrated in the sealing strip.
  • the lubrication is implemented by means of a number of spray nozzles which make the outlet openings 5 available.
  • the spray nozzles are connected to the inner section 7 of the supply line via inlet segments 9.
  • FIG. 3 Another beneficial feature found in Figure 3 is realized together with the spray nozzles, which is also possible in combination with a lubrication device 4 integrated in the sealing strip 3, consists in the inner section 7 of the supply line at least partially running at least partially on or in the sealing strip holder 3a.
  • This inner section 7 provides the storage volume of at least 500 cm 3 / m available and can, for example, have the shape of a cylinder or a tapering cylinder.
  • FIG 4 are once again shown schematically essential components of the invention.
  • the lubricant outlet openings 5 are supplied with lubricant via inlets 10, 10a.
  • the inlets 10, 10a are connected to the inner section 7 of the supply line via inlet segments 9, 9a.
  • the distances from the longitudinal end of the sealing strip 3 to the first inlet 10a or to the first inlet segment 9a are denoted by d1 or d5, while the distances between adjacent inlets 10, 10a or adjacent inlet segments 9, 9a to one another are denoted by d2, d3, d4 is designated.
  • the number of 4 inlets is exemplary. More or fewer inlets / inlet segments can certainly also be provided.
  • the 'inner' distances d2-d4 can be the same or differ by a few millimeters. This can be due, for example, to the installation situation.
