Definitions

  • the invention relates to a roller lever module for a grinding roller of a roller mill, which has a rotating grinding table and grinding rollers rolling thereon.
  • the roller lever module has a roller lever, at the end of which a grinding roller can be fastened on the grinding plate side.
  • a guiding and storage unit with a guiding axis is also provided.
  • the side of the roller lever facing away from the grinding plate is coupled to the guide and bearing unit, with the guide and bearing unit being designed as a linear guide for displacing the roller lever axially along the guide axis, according to the preamble of claim 1.
  • a roller mill with a corresponding roller lever module is also claimed.
  • Roller mills are used for crushing any type of material to be ground.
  • a rotating grinding table is usually provided, on which stationary, rotating grinding rollers roll. These are not necessarily driven, but are often set in rotation by the material to be ground, which is on the rotating grinding table. Since the material to be ground does not form an ideal grinding bed on the grinding table, it is necessary for the grinding rollers to be able to change their distance from the grinding table.
  • Various constructions are known for this. It is essential here that the design allows sufficient freedom of movement for the grinding rollers. Such constructions are referred to as roller lever module.
  • the grinding rollers themselves are each connected to an axle which is mounted in the roller lever.
  • the roller lever itself is connected to the roller lever module.
  • the construction is essential here so that the compensating movements described above can be carried out. Since vibrations also occur during the grinding process, it is also necessary to absorb and dampen them, ideally using the roller lever modules.
  • roller lever module The construction of a roller lever module is, for example, from WO 2017/137056 out.
  • the roller lever is fastened in a fork-like device, which in turn allows the roller lever to pivot in an axis perpendicular to the axis of rotation of the grinding roller.
  • a disadvantage of the known systems is that they often have a relatively large design.
  • mill technology however, there is a trend towards larger and larger mills, which in turn have several grinding rollers.
  • roller lever modules as compactly as possible, so that as many grinding rollers as possible can be arranged around a grinding table in a space-saving manner.
  • a roller lever module for a grinding roller of a roller mill with a roller lever is known, at the end of which a grinding roller can be fastened on the grinding plate side.
  • a guiding and bearing unit with a guide axis is also provided, the roller lever being coupled to the guiding and bearing unit and the guiding and bearing unit being designed as a linear guide for displacing the roller lever axially along the guide axis.
  • the U.S. 4,218,023 A refers to roller lever modules with hydrostatic thrust bearings, the latter being able to support the grinding table and absorb the vertical loads.
  • the invention is therefore based on the object of specifying a roller lever module which has a compact construction.
  • this object is achieved by a roller lever module having the features of claim 1 .
  • the roller lever module according to the invention is further developed in that the guiding and bearing unit has a central body that is elongated in the direction of the guiding axis, with the central body being surrounded by an outer sleeve.
  • the outer sleeve is arranged and/or attached to the central body so that it can be displaced in the direction of the guide axis.
  • At least one linear guide bearing is provided between the outer sleeve and the central body.
  • a unit for transmitting a torque from the roller lever to the central body is arranged between the outer sleeve and the central body.
  • the invention is based on the idea of distributing the forces acting on the grinding roller and thus on the roller lever over different units.
  • the roller lever module must be able to withstand the loads arising from the roller force, i.e. the pressure with which the grinding roller presses the material to be ground on the grinding table, and the loads from the bowl rotation, i.e. in particular the torques generated by the rotation of the bowl via the Material to be ground on the grinding roller and are thus transferred to the roller lever.
  • two separate devices are provided for receiving and forwarding the corresponding loads.
  • the forces and loads that arise from the pressure of the grinding rollers themselves are absorbed and transmitted in particular by the at least one linear guide bearing.
  • the forces are absorbed by the elongated central body and introduced into a foundation via a bracket provided for it.
  • the forces, in particular the torques, resulting from the rotation of the bowl are transmitted to the central body via the unit for transmitting a torque.
  • the at least one linear guide bearing also serves to enable the roller lever and thus the grinding roller connected to it to be able to move in the direction of the guide axis.
  • unevenness on the grinding bed can be compensated.
  • the grinding gap i.e. the standard distance between the grinding roller and the grinding table, can also be set here. This is advantageous, for example, when different materials are to be ground.
  • any type of bearing can be used as a linear guide bearing.
  • a hydrostatic bearing is used for this.
  • Hydrostatic bearings have a high power density, which in turn enables the compact design of the roller lever module.
  • first linear guide bearing in the upper area of the central body and the second linear guide bearing in the lower area be arranged of the central body. Such an arrangement promotes good transmission of the forces generated on the roller lever to the central body.
  • this arrangement offers to arrange the unit for transmitting the torque between the at least first and the at least second linear guide bearing.
  • the unit for transmitting the torque can be arranged centrally.
  • the unit for transmitting the torque can be designed in any way.
  • this is to design this as a curved tooth coupling.
  • parts of the curved tooth coupling for example teeth, can be formed on the central body.
  • it can also be provided to provide an inner sleeve which surrounds the central body. This can be arranged in a rotationally fixed manner on the central body.
  • corresponding components of the curved tooth coupling can also be formed on the inner sleeve instead of on the central body. This offers the advantage that the inner sleeve can be replaced if damaged, but the central body can still be used.
  • the teeth or engagement parts on the inner sleeve or on the central body have a longer extension along the guide axis than the teeth or engagement elements which are formed on the inside of the outer sleeve.
  • the unit for transmitting the torque is also designed as a correspondingly arranged and dimensioned hydrostatic bearing.
  • the advantage of using a curved tooth coupling is that it has a small size and can be easily integrated into a compactly dimensioned roller lever module.
  • the linear guide bearing can be designed as a hydrostatic bearing.
  • the hydrostatic bearing can have a bearing sleeve which essentially has an inside diameter which corresponds to the outside diameter of the central body or the inner sleeve.
  • various elements can be provided on the bearing sleeve or can be formed on or in it.
  • the bearing sleeve prefferably has radial lubricant supply channels.
  • axial lubricant return channels can be provided on the bearing sleeve.
  • pressure pockets can be formed on the inside of the bearing sleeve.
  • the lubricant supply channels preferably extend radially through the bearing sleeve and serve to supply lubricant from the outside of the bearing sleeve to its inside. Supplied lubricant can then flow upwards or downwards through the axially arranged lubricant return channels on the inside of the bearing sleeve.
  • the pressure pockets provided on the inside of the bearing sleeve serve to hold lubricant at least temporarily. The lubricant flows via the lubricant supply channels into the pressure pockets and remains in them or is continuously exchanged by transporting approximately the same volume through the lubricant return channels, which volume is simultaneously added through the lubricant supply channels.
  • a free space between the outer sleeve and the central body is filled with lubricant. If an inner sleeve is provided, the free space is between the outer sleeve and the inner sleeve.
  • the space that is not yet occupied by components after the arrangement of one or more linear guide bearings and the unit for transmitting a torque can be referred to as free space.
  • Lubricant is used for good lubrication of the components arranged there and thus supports the longevity of the construction of the roller lever module.
  • a lubricant suction device can be provided at the upper end of the roller lever module.
  • hydrostatic bearings which ideally have a continuous supply of lubricant, it is necessary to drain the supplied lubricant again.
  • the arrangement of the lubricant suction in the upper end area of the roller lever module has the advantage that it ensures that a sufficiently high level of lubricant is present in the free space mentioned.
  • a particularly reliable operation of the roller lever module can be achieved if the pressure in the free space is essentially ambient.
  • the lubricant in the free space is not under pressure, but is merely pumped through and sucked off at the lubricant suction device arranged in the upper area, for example, with the same volume per unit of time as it is, especially in the area of the hydrostatic Stock, is supplied.
  • Sealing of the free space of the roller lever module can be achieved, for example, by providing a piston ring seal in the upper and lower area.
  • the roller lever which has the axis of the grinding roller, is preferably attached to the outer sleeve. This type of attachment also allows a relatively compact structure.
  • a hydraulic cylinder can be provided on the grinding roller lever. This is preferably aligned with a push or pull direction essentially parallel to the central body or the guide axis of the guiding and bearing unit.
  • the grinding roller lever module according to the invention is preferably used in a roller mill with a grinding table and grinding rollers rolling on it.
  • per Grinding roller provided a grinding roller lever module.
  • the roller lever module can also be referred to as a grinding roller lever module.
  • the grinding roller lever modules Due to the compact design of the grinding roller lever modules according to the invention, it is possible to provide two grinding roller lever modules on a common stand, which can be made of concrete, for example. This in turn allows for a relatively compact structure around the roller mill, so that there is enough space for other devices required for operation.
  • figure 1 is a simplified representation of a roller mill without a housing and classifier and without other components that are not essential to the invention.
  • Three stands 102 are provided here around a centrally arranged grinding table 101 .
  • a bearing block is provided for each roller lever module.
  • the dedicated bearing block can then be provided with a second bearing block on a common stand, but also on a separate stand in each case.
  • a roller lever module 1 consists essentially of a roller lever 3 and a guide and bearing unit 20.
  • a grinding roller 10 is provided at the end of the roller lever 3 on the grinding plate side. This is non-rotatably connected to an axis which runs within the roller lever 3 .
  • the grinding table 101 is only shown as a ring. In a non-simplified representation of a roller mill, it is usually an essentially circular disk.
  • the grinding table 101 is set in rotation.
  • material to be ground is transported outwards to the grinding rollers 10 by means of centrifugal forces.
  • the material to be ground which is transported under the grinding rollers 10 is comminuted on the one hand by the pressure which the grinding rollers 10 exert on the material to be ground.
  • the contact with the material to be ground ensures that the grinding rollers 10 rotate about their axis.
  • FIG. 1 An enlarged representation of a stand 102 with two roller lever modules 1 is shown in 2 shown.
  • Each roller lever module 1 has its own bearing block 30 .
  • the guiding and bearing unit 20 of each roller module 1 is fitted into this.
  • a linear movement of the grinding roller 10 perpendicular to the grinding table 101 is possible by means of the guide and bearing unit 20, to which the roller lever 3 is fastened.
  • the detailed structure of the guiding and storage unit 20 is described below with reference to FIG 3 described in more detail.
  • a hydraulic cylinder 5 is provided between the stand 102 and the roller lever 3 . This serves to vary the force that is applied to the grinding bed on the grinding table 101 by means of the grinding roller 10 . If the hydraulic cylinder 5 pulls, this force is increased; if it presses, the force can be reduced. In more detail, increasing the hydraulic pressure on the piston rod side results in a higher pulling force on the piston rod. Decreasing the hydraulic pressure on the piston rod side results in a reduction in force, as does increasing the hydraulic pressure in the piston-side cylinder chamber, which is at the bottom in this figure. This can even lead to the rollers being lifted off if the compressive force is greater than the weight of the moving system.
  • FIG. 3 a sectional view of a guiding and bearing unit 20 of a roller lever module 1 according to the invention is shown.
  • a central body 22 which is cylindrical.

  • the outer sleeve 24 is preferably attached in a linearly displaceable manner in the axial direction of the central body 22 .
  • larger portions of the curved tooth coupling 31 are formed on the inner sleeve 25 provided fixed to the central body 22 .
  • Smaller parts that engage, in particular mesh, with the areas on the inner sleeve 25 are provided on the outer sleeve 24 . With a linear displacement of the outer sleeve 24, these parts move within the parts that are provided on the inner sleeve 25, so that a power or torque transmission is still possible.
  • a hydrostatic bearing 26 , 28 is arranged in each case in the lower and upper area of the guiding and bearing unit 20 . This extends between the outer 24 and the inner sleeve 25. At the contact area between the outer sleeve 24 and the inner sleeve 25, a suction point 36 is provided, at which the lubricant introduced for the hydrostatic bearing 28 can be sucked off again.
  • a seal for example a piston ring seal 34, is provided at the lower contact point between the outer sleeve 24 and the inner sleeve 25 in order to seal the clearance 27 between the sleeves 24, 25 so that the lubricant can only be removed via the suction point 36.
  • a similar seal can also be provided at the upper contact point or at the contact surface between the outer sleeve 24 and the inner sleeve 25 .
  • the roller lever 3 itself is attached to the outer sleeve 24 .
