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 5, and a method for operating a roller according to the preamble of claim 6
- Sealing devices in vacuumed or blown rollers for paper, cardboard or tissue machines must reliably seal the overpressure or underpressure zone from the environment in which normal pressure prevails.
- the sealing surface of each sealing strip of the sealing device is placed against the inside of the rotating roller shell. In order to reduce the wear of the sealing strip caused by friction between the outer surface and the sealing surface, an attempt is made to introduce a lubricant between the sealing surface and the inside.
- EP2885457 and EP3022356 propose that the lubricant be led directly to the upper side of the respective sealing strip, which provides the sealing surface, in order to supply each individual sealing strip with the required amount of lubricant in a targeted manner.
- 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 recess arranged next to the sealing surface and extending in the longitudinal direction of the sealing strip, that is to say in the cross-machine direction of the roller, possibly with the aid of a suitable lip.
- 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 characterizing Part of claim 5 and with regard to the method by a method for operating a roller according to the characterizing of claim 6.
- a sealing device for sealing an overpressure or underpressure zone of a roll 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 between the inside of the roll casing and the sealing surface the sealing strip can be brought
- the lubrication device comprises a plurality of lubricant outlet openings and can be connected to a supply line for supplying lubricant.
- the sealing device is characterized in that the lubricating device can be connected to the supply line via a plurality of 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 an inlet is a maximum of 1000mm, especially a maximum of 800mm, in particular a maximum of 600mm, preferably 400mm or less.
- Such a sealing device can be particularly advantageous for supplying the edges of the sealing strip with lubricant sufficiently and uniformly.
- each point can be supplied with lubricant both from the right and from the left, since there is at least one inlet on both sides through which lubricant is fed to the lubrication 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 also with less lubricant, than the central region 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 15 m or less.
- the inlets can also be arranged in such a way that the distance between adjacent inlets is equal to one another in the longitudinal direction of the roller or does not differ from one another by more than 500 mm.
- the lubrication device can preferably be provided entirely or partially in or on the sealing strip, in particular the lubricant outlet openings being able to be in the sealing strip. Furthermore, it can be advantageous if 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 too close to the longitudinal end of the sealing strip, the effect can occur that the lubricant supplied either passes beyond the end of the sealing strip. In order 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 lubricating device is provided in whole or in part 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 particular in the sealing strip holder.
- a roller which comprises at least one sealing device according to one aspect of the invention.
- Water can usually be used as the lubricant, to which additives can optionally be added.
- the pressure in the The supply line can be, for example, between 2 and 8 bar, in particular 3 bar to 6 bar.
- a roller for a machine for producing or processing a fibrous web which has a movable roller shell and a comprises an overpressure or underpressure zone arranged within the roller shell and non-rotatable in comparison to the roller shell, and a sealing device for sealing the overpressure or underpressure 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 a plurality of 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 roll shell 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 is to 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 according to one aspect of the invention.
- the size of the storage volume should be at least 500 cm 3 / m.
- the value of 500 cnrvVnn is sufficient for the lubricant quantities usually used from 0.5 l / m / min to approx. 3 l / m / min.
- Larger storage volumes of 1000 crmVnn, 2000 cm 3 / m or more are advantageous for reasons of pressure equalization as described above. Due to the installation space, which is quite narrow in some rollers, or also for economic reasons, it can make sense to limit the size of the storage volume. So it can be advantageous to provide the storage volume not larger than 20,000 cnrvVnn or 10,000 cmVm.
- the indication of the storage volume in "cm 3 / m" refers 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.
- the inner section comprises or consists of a tubular part which extends essentially over the entire length of the sealing strip, this tube having an inner diameter of 25 mm or more, in particular, at at least one point has more than 40mm, preferably 50mm or more.
- the tube has a constant cross section over more than 50% of its length, in particular over its entire length.
- a pipe that has an inner diameter of 25mm over its entire length already provides more than 500 cnrvVnn of storage volume.
- the tube tapers continuously over its length.
- Such an embodiment 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 back in the direction of flow of the lubricant still constant.
- it can further be provided that 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%.
- such 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 versions the distance between adjacent lubricant outlet openings is between 40mm and 60mm.
- 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, by the lubricant being transferred from the inlet segments to nozzle devices, e.g. Fan nozzles is guided, which represent the lubricant outlet openings.
- the lubricant is lubricated in the direction of the sealing surface to be lubricated via the nozzles.
- These nozzle devices are known as lubricating spray pipes and are usually arranged in the direction of rotation of the roller in front of the sealing strip.
- the lubrication device can also be advantageous for the lubrication device to be provided entirely or partially in or on the sealing strip, in particular the
- Lubricant outlet openings are in the sealing strip.
- Such sealing strips with an integrated lubrication device are often preferred because the sealing surface can be lubricated with a smaller amount of lubricant.
- the inner section is at least partially rigid. The term "rigid" is to be understood in comparison to the inlet segments. Inlet segments are often wholly or at least partially as
- Plastic hose executed. This is particularly useful for sealing strips with an integrated lubrication device, since the inlet segment has to move with the movement of the strip due to wear.
- the inner section of the supply line is at least partially made of a rigid material, for example in the form of a metallic tube or a plastic tube. Sealing devices often have a so-called holder for receiving the sealing strip. In a preferred embodiment it can be provided that the inner section runs at least partially on or in this holder.
- all inlet segments have the same length or differ in their length by less than 25%. If there are too large differences in the lengths of the inlet segments, there may be a risk that the effect of the equalization of the pressure cannot be completely 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 vacuum zone.
- this mounting position is more easily accessible 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 shorter inlet segments with a length of, for example, 150 mm to 250 mm can be used.
- 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 extends essentially outside 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, via an end face Inside the roller is guided where it is connected to the inner portion.
- 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 of the invention, characterized in that the lubricating device with less than 2.4 l / min / m, lubricant is supplied in particular between 0.4 l / min / m and 1.5 l / min / m. With such a quantity of lubricant, the roller proves to be particularly advantageous in accordance with 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 is 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 s, in particular between 30 s and 5 min.
- Such a start period which precedes standard operation, can ensure, among other things, that the storage volume is completely filled with lubricant and thus the roller or the lubrication device can develop its full effect. This is particularly advantageous in the case of rolls in which an inner section of the supply line has a storage volume which, as stated in the further idea, is at least 500 cm 3 / m.

- the inlet segments 9, 9a can for example be designed as hose segments.
- FIG. 2 differs from Figure 1 in that the inner portion 7 consists of a tube 7 which tapers continuously over its length.
- FIG. 3 shows a sealing strip 3 in a holder 3a, 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 roller jacket is a common measure known to the person skilled in the art.
- the lubrication device 4 is not integrated in the sealing strip in FIG. 3.
- the lubrication is carried out 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.
- Another advantageous feature which is implemented in FIG. 3 together with the spray nozzles, but which is also possible in combination with a lubrication device 4 integrated in the sealing strip 3, consists in the fact that the inner section 7 of the supply line is at least partially at least in or on the Sealing strip holder 3a runs.
- This inner section 7 provides the storage volume of at least 500 cm 3 / m, and can for example have the shape of a cylinder or a tapered cylinder.
