Definitions

  • the invention relates to a press roller for a roller press for briquetting, compacting or grinding granular material, with a roller core and a cooled or coolable bandage attached to the roller core.
  • a roller press usually has two press rollers rotating in opposite directions.
  • the bandage is usually pressed on the outer circumference with pressing tools, e.g. B. mold cavities for briquetting or compacting.
  • pressing tools e.g. B. mold cavities for briquetting or compacting.
  • the invention also includes press rolls with bandages that are provided with another wear protection layer, e.g. B. for the (high-pressure) crushing of material.
  • the press rollers are exposed to high temperatures due to the material to be processed, so that the bandages themselves also assume high temperatures.
  • the bandages and in particular the pressing tools attached to them are usually subject to high wear.
  • a press roll with cooling is also from the DE 25 36 670 A1 famous.
  • the roller core is cooled via a plurality of axially parallel cooling channels which are integrated into the roller core itself.
  • the shell of the roller consists of a plurality of segments which adjoin one another on the circumference with axially parallel longitudinal edges and are detachably connected at their ends to the roller core.
  • the jacket is formed by a plurality of segments that are detachably fastened to the core.
  • the axially parallel cooling channels introduced into the segments are connected to the radial bores introduced into the roll core via suitable connecting means, e.g. B. elbow connected.
  • suitable connecting means e.g. B. elbow connected.
  • a press roller according to the preamble of claim 1 is from DE 198 33 456 A1 famous.
  • deflection or distribution rings are attached to the side of the bandage and sit directly on the end faces of the bandage.
  • the deflection or distribution rings have, on their inner side associated with the end face of the bandage, circumferential annular grooves which distribute the cooling medium over the entire end face region of the bandage covered by the deflection ring.
  • the deflection and distribution rings are each connected to the radial inlet and outlet channels via separate pipe connections.
  • the invention is based on the technical problem of creating a press roller for a roller press of the type described at the outset, which is distinguished by an improved cooling concept.
  • the invention teaches a press roller for a roller press with the features of claim 1.
  • Such a press roll is intended for briquetting or compacting and particularly preferably for hot briquetting or hot compacting.
  • the invention also includes press rollers for crushing or grinding granular material.
  • the invention is initially based on the finding that effective cooling is achieved by cooling channels arranged within the bandage. Consequently, the cooling channels are arranged very close to the surface of the drum or close to the pressing tools and/or anti-wear layers arranged on the drum, so that the cooling is implemented where the heat is also supplied.
  • Such an effective cooling leads in particular to longer service lives and lower maintenance costs, because the wear of the bandage or the pressing tools arranged on it is reduced significantly reduced.
  • due to the cooling of the bandage there is the possibility of attaching the one-piece and completely circumferential (annular) bandage perfectly to the roller core, specifically by thermal shrinking. There is no longer any risk of the shrunk-on bandage detaching from the roller core due to heating.
  • the performance of the roller press is improved by the cooling, because overall it is possible to work with higher throughputs without increasing the tool temperature. Furthermore, the cooling and the resulting stress-optimized design prevent damage, e.g. B. avoided by cracking.
  • the cooling liquid preferably water or the like.
  • the cooling liquid preferably water or the like.
  • the cooling medium passes from the central channel via the inlet and outlet channels oriented in the radial direction into the distribution ring and is distributed there via the ring channel to the individual axially parallel cooling channels.
  • the radial inlet and outlet ducts on the one hand and the axially parallel cooling ducts on the other hand are connected via the distributor rings, specifically without separate pipe systems, steel corrugated hoses or the like.
  • the distributor rings are each arranged in the area of the radial inflow and outflow channels on the roller core, so that they cover the radial inflow and outflow channels.
  • the distributor rings attached to the bandage on both sides extend beyond the radial inlet and outlet channels, so that the distributor rings are attached to the roller core directly with the interposition of seals and without the use of separate pipes, steel corrugated hoses or the like and can be connected to the radial inlet and outlet channels.
  • the seals between the distributor ring and the roll core are particularly preferably ring-shaped sealing elements, e.g. B. O-rings.
  • the seals between the distributor ring and bandage are particularly preferably flat seals.
  • the configuration according to the invention is characterized by a particularly simple structure and optimized cooling.
  • the absence of separate connecting pipes or the like makes it possible to fully utilize the width of the roller, so that wider drums or segments can be used.
  • This also optimizes the cooling, so that, surprisingly, the distributor rings can be connected directly to the roll core with the interposition of suitable seals, despite the high temperatures, without z.
  • B. corrugated hoses are required.
  • the distributor rings are particularly preferably each designed as a completely circumferential, one-piece distributor rings, e.g. B. made of steel.
  • the necessary channels can be machined into the distributor rings.
  • These separate distribution rings also have the Advantage that they can be used several times independently of the bandage, e.g. B. if the bandage is to be replaced after wear and tear. So there is z. B. the possibility of attaching the distribution rings only to the bandage (and not to the roll core), z. B. detachable by means of screw connections.
  • the distributor ring can be produced particularly easily if the distributor rings are provided with grooves on the inner circumference, which extend in the inner circumferential direction over at least part of the inner circumference and which form the annular channels when the distributor ring is assembled with the roller core. Consequently, it is not necessary to integrate the ring channels "completely" into the distributor rings, but in terms of production technology, open grooves can easily be introduced on the inner circumference, so that the ring channels are then ultimately created in the course of assembly, with the ring channels then being limited on one side by the surface of the roller core will.
  • Seals are preferably provided between the bandage and distributor ring on the one hand and the bandage and roller core on the other.
  • a seal between the distribution ring and the roll core is particularly useful when the ring channels are formed by the grooves described. Seals between the distributor ring and bandage are advantageous because the ring channel is connected to the individual cooling channels via corresponding connecting channels.
  • B. can be designed as deflection channels. As seals z. B. graphite seals or graphite laminate seals are used.
  • each distributor ring only a single annular channel running all the way around the entire circumference is integrated in each distributor ring.
  • This has the advantage that only one radial inlet or outlet hole is required for each distributor ring, so that the stability of the roll core is only minimally affected.
  • several ring channels can also be incorporated into each distributor ring, each of which does not extend over the entire circumference, but over a certain circumferential angle of z. B. 90 ° to 180 ° and are each connected via separate inlet and outlet channels to the central channel. So e.g. B. be worked with two ring channels per distributor ring, each extending over a circumferential angle of 180 °.
  • Such an embodiment has the advantage that the distribution of the cooling medium can be optimized in particular with regard to distribution that is as uniform as possible and thus a homogeneous cooling capacity.
  • two ring channels are then only two feed channels and two discharge channels required, so that you can also work with relatively few holes in the roll core.
  • the homogeneous cooling distribution could be optimized by a further division into a large number of ring channels. However, this could then impair the stability of the roller due to the large number of radial bores then required, so that preferably no more than four ring channels or channel sections per distribution ring are used.
  • throttle devices into the cooling channels or into some cooling channels, which reduce the flow cross section of individual cooling channels by a predetermined amount.
  • the invention is based on the knowledge that it makes sense in terms of manufacturing technology to begin with To produce cooling channels with the same cross-section.
  • inhomogeneous cooling can then occur since, starting from the radial feed channel, not all of the cooling channels are evenly charged with cooling liquid.
  • this fact can be taken into account by providing some cooling channels with suitable throttle devices. These are preferably simple reductions in diameter, the z.
  • B. can be realized through the use of suitable ring elements or panels that are integrated into the cooling channels or are assigned to the cooling channels. These elements or baffles are preferably not integrated directly into the cooling channels, which are arranged directly in the bandage, but rather into the adjacent sections in the distributor rings. It can be determined in advance by appropriate calculations and particularly preferably by appropriate tests, which cooling lines are to be provided with appropriate throttling devices or which throttling devices are to be provided for a corresponding cooling capacity, it being possible for different throttling devices to be used in different cooling lines. It can be expedient to reduce the diameter of individual cooling lines by more than 20%, possibly even more than 40%. In any case, with the help of appropriate throttling devices, an overall flawless, homogeneous cooling can be implemented, even when working with only one or two annular ducts per distributor ring.
  • the distribution ring is preferably made of steel.
  • the bandage can also be made of steel, with the pressing tools arranged on the bandage and the wear layer preferably being produced by powder metallurgy and attached to the bandage, e.g. B. by hot isostatic pressing (HIP).
  • the cooling channels that are essential to the invention are therefore particularly preferably used in a bandage whose pressing tools and/or wear protection layer are powder-metallurgically, e.g. B. is made by hot isostatic pressing.
  • the invention is implemented in a one-piece, completely circumferential ring bandage. This is shrunk onto the core.
  • a press roller for a roller press in particular for briquetting or compacting and particularly preferably for hot briquetting or hot compacting of granular material.
  • a press roll exists in its basic structure of a roll core 1 and a bandage 2 attached to the roll core 1.
  • the roll core 1 is formed in one piece with a shaft 3 which is rotatably mounted in a machine frame, not shown, with the interposition of bearings 5.
  • the bandage 2 is designed as a completely circumferential, one-piece ring bandage, which is attached to the roller core 1 by thermal shrinkage.
  • the bandage 2 is equipped with pressing tools 4 which, for. B. can be designed as mold cavities for briquetting or compacting. This pressing tool 4 is only indicated in the figures.
  • the bandage 2 is z. B. made of steel, the pressing tools 4 as a wear layer z. B. powder metallurgy and applied to the bandage 2, z. B. by hot isostatic pressing. In this way, a one-piece bandage 2 with integrated tools or mold cavities is produced.
  • the press roll is equipped with liquid cooling, e.g. B. water cooling equipped.
  • liquid cooling e.g. B. water cooling equipped.
  • a multiplicity of cooling channels 6 distributed over the circumference and running parallel to the axis are integrated into the bandage 2 below the surface of the bandage or below the tools 4, which run parallel to the axis. It can be seen that these axially parallel cooling channels 6 are not integrated in the roll core 1 but in the bandage 2, so that the roll surface or the tools 4 are cooled particularly effectively.
  • These axially parallel cooling channels are connected to an axial central channel 8 in the roll core 1 via radially running inflow and outflow channels 7 .
  • This central channel 8 is connected via a suitable rotary feedthrough to a liquid inlet and outlet device 9 which is attached to the side of the roller shaft 3 .
  • the cooling medium is distributed via two distributor rings 10, each of which is connected to the bandage at the front.
  • B. can be made of steel and are connected to the bandage 2 laterally.
  • One or more annular ducts 11 are integrated into each of these distributor rings 10, which run along the circumferential direction of the distributor rings 10 and which are connected on the one hand to the radial inlet and outlet ducts 7 and on the other hand to the axially parallel cooling ducts 6.
  • a simple distribution of the cooling medium consequently takes place via these separate distribution rings 10 .
  • One of the rings 10 forms a distribution ring over which the liquid is distributed, and the other opposite ring forms a collection ring, so to speak.
  • the term "distribution ring" consequently also includes its collection function.
  • the radial inlet and outlet channels 7 on the one hand and the axially parallel cooling channels 6 on the other hand are connected exclusively via the distributor rings 10 without separate pipe systems or steel corrugated hoses.
  • the distribution ring 10 is sealed with the interposition of seals 14, 15 on the one hand against the drum 2 and on the other hand against the roller core 1.
  • the distributor rings 10 are each arranged in the area of the radial inlet and outlet channels 7 on the roller core 1, so that the distributor rings 10 cover the inlet and outlet channels 7, so to speak. In this way, almost the entire roll width for the bandage 2 can be used.
  • the seals 14, 15 are designed as annular seals.
  • Two perforated flat gaskets 14 are provided between the distributor ring 10 and the bandage 2, preferably one flat gasket 14 per distributor ring 10.

  • grooves 13 are made in the inner circumference of the distributor rings 10 to implement the ring channels 11, which extend in the inner circumferential direction over at least part of the inner circumference and which form the ring channels 11 when the distributor ring 10 is in the installed state with the roller core 1.
  • the groove 13 can be seen, which is introduced into the distributor ring 10 on the inner circumference, e.g. B. by machining.

  • the seals 14 , 15 are arranged both between the distributor ring 10 and the bandage 2 and between the distributor ring 10 and the roller core 1 .
  • FIG. 12 also shows that the distributor rings 10 are detachably attached to the bandage 2 by means of screw connections. Suitable openings are required for this, e.g. B. holes 16 are introduced into the distributor rings 10, through which corresponding screws 17 can be introduced into the bandage. A separate attachment of the distribution rings 10 to the roller core 1 can be dispensed with. Particularly advantageous is the fact that the distributor rings 10 can be used several times, independently of the bandage, e.g. B. after appropriate wear of the bandage 2.
  • each distributor ring 10 does not just have a single completely circumferential ring channel 11 integrated, but rather that two ring channels 11 are integrated in each distributor ring 10, each of which (only) extends over a circumferential angle of 180°.
  • Each of these ring channels 11 is connected to the central channel 8 via a (single) inlet channel or outlet channel 7 .
  • the distribution of the cooling medium is improved by realizing two separate ring channels and consequently two separate cooling systems. Nevertheless, it is not necessary to introduce a large number of radially running channels into the core, so that a stable design is ensured.
