Definitions

  • the invention relates to a rotatable roller with a roller body, having correlated therewith channels for guiding a medium therethrough for the purpose of temperature control of the roller body, the medium being, in particular, a liquid.
  • rollers are used in many fields of application, for example, in the manufacture of paper, in the foodstuff industry, as well as in rolling processes of plastic or steel, for example, for continuous casting and rolling in a continuous casting process. It is known in this context to provide roller bodies with channels, extending axially in the roller and near the surface, for temperature control of the roller bodies, for example, for heating them. Such rollers, for example, are disclosed in EP 0 606 660 A1.
  • this is achieved in that at least one of the channels has correlated therewith a separating member so that tempering media of different consistency and/or temperature and/or flow direction and/or flow speed can flow within one channel.
  • this object is achieved in that at least one deflecting member correlated with at least one area of the channel and acting on the medium is provided which imparts an additional flow direction to the substantially axially oriented flow of the tempering medium.
  • the deflecting member for this purpose is characterized by at least one deflecting area which is positioned at a slant relative to the longitudinal axis of the deflecting member.
  • the medium flow is provided with a smaller cross-section in the channel so that the speed of the tempering medium is increased and an improved temperature transfer is ensured.
  • the channel divided in this way can be used simultaneously for supplying and returning the tempering medium.
  • a division of the channel into halves, thirds or fourths is advantageous. Even divisions by greater numbers are possible.
  • the separating member has the shape of a multi-start helix so that a turbulence of the tempering medium can be achieved simply by means of the helical configuration.
  • the residence time of the tempering medium is increased as a result of the longer travel path. The turbulence, the increase of the residence time, and the speed increase caused by the channel constriction result in an optimal heat transfer.
  • the deflecting area can extend over a large longitudinal area of the channel.
  • the heat transfer is then improved over a large longitudinal area of the channel.
  • turbulence is achieved in the areas neighboring the channel walls. The efficiency is thus especially good.
  • the deflecting member can have a rigid longitudinal or form a deflection area as a whole, for example, in the way a coil spring.
  • the roller areas can be loaded in a targeted way with different intensity of the tempering media.

  • several such channels are arranged in a roller.
  • Such a roller body is provided on both ends with flange pins by which a connection of the channels to an outer supply with heating or cooling media is ensured.
  • a central axial hollow space in the hollow roller (FIG.
  • a flow channel 401 for tempering media can be used as a flow channel 401 for tempering media wherein this channel 401 , for example, is a supply line and a peripheral channel 1 , 101 , 201 , 301 , 501 , 601 can serve as a return line or vice versa.
  • the central flow channel 401 can be provided with a deflection member 405 for an improved adjustment of the flow conditions, wherein the deflection member 405 with regard to its size is matched to the axial and radial extension of the hollow space or chamber.
  • FIG. 3 shows a straight channel 1 which has at one roller end an inlet E and at the other roller end an outlet A for the flowing medium.
  • FIG. 5 a channel 101 is illustrated whose inlet E and outlet A are positioned on the same side of the roller surrounding the channel. Opposite the inlet and outlet an axial end portion 102 is provided in which a 180 ° bend of the channel 101 is formed so that the return path 103 to the outlet side is provided.
  • two deflections or bends 202 are formed so that the inlet side E and the outlet side A of the channel 201 are positioned on opposite sides of the roller.
  • three bends 302 are provided so that the inlet E and outlet A of such a channel 301 are again positioned on the same side of the roller body. All such channels 1 , 101 , 201 , 301 penetrate preferably substantially or completely the roller body in the direction of its axial extension.
  • the channel 501 is formed such that two externally positioned inlet lines E are guided to a central outlet line A.
  • the number of inlet and outlet openings E, A is thus different.
  • the channel 601 according to FIG. 7 c has three inlet openings E and one outlet opening A so that here the number of inlet openings and outlet openings E, A -is also different.

  • the deflecting member 5 compromises a deflecting area 7 which is formed as a screw guided about the longitudinal axis 6 and which is positioned at a slant relative the longitudinal axis 6 .
  • the deflecting areas 7 are positioned at an acute angle relative to the walls 1 a of the channel 1 , 101 , 201 , 301 , 501 , 601 .
  • the deflecting member 5 , 105 according to FIG. 2 comprises a rigid central axle 106 about which the slantedly positioned and coil-shaped deflecting areas 107 extend.
  • the deflecting areas can be formed continuously like a screw over the entire longitudinal extension L of the deflecting member 105 , or individual slantedly positioned deflecting areas 107 can be provided.
  • the deflecting member 205 is formed as a whole as a coil spring body so that the longitudinal axis 6 is only surrounded by the deflecting areas 207 .
  • FIGS. 3 and 5 show a deflecting member 205 for use in a channel 1 or 101 which is arranged in a roller body of a roller, for example, in the form of a hollow cylindrical roller, that is to be temperature-controlled (tempered).
  • a deflecting member 205 for use in a channel 1 or 101 which is arranged in a roller body of a roller, for example, in the form of a hollow cylindrical roller, that is to be temperature-controlled (tempered).
  • tempered temperature-controlled
  • deflecting members 5 , 105 , 205 , 405 create a turbulent flow in the heating medium so that the individual flowing particles must travel a longer distance within the channel 1 , 101 , 201 , 301 , 401 , 501 , 601 and the residence time and thus also the energy transfer time are increased. This effect is maintained also for a point-directed increased flow velocity of the particles of the medium as it can be caused by turbulences.
  • deflecting members 5 , 105 , 205 , 405 are possible which have deflecting areas 7 , 107 , 207 , 407 that are not shape-stable but are to be formed by the oncoming medium so that in this way a chaotic flow of the medium results. This can change upon a change of the temporal course or when changing the pressure of the medium as it is guided through.
  • the incline of the deflecting area 207 or the length L of the deflecting member can be varied, optionally during operation, in order to be able to affect the type of turbulences and the possibly additionally formed rotation and to thus be able to affect the parameters flow speed, liquid amount to be introduced, or gas amount, residence time, and turbulence of the introduced medium.
  • the incline of the deflecting areas 7 , 107 , 207 , 407 can be varied so that areas 7 a with minimal incline and areas 7 b with large incline are present. Areas with identical or different incline 7 a , 7 b can be furthermore spatially spaced from one another.
  • FIG. 9 shows a separating member 50 in the form of a two-start helix 70 that can be inserted into a channel.
  • the incoming flow of the tempering medium can be guided within a channel portion formed by one of the helix strands and the return flow of the tempering medium can be guided in the other channel portion defined by the other helix strand.
  • the supply and return of the medium can be provided within a single channel.
  • the supply of the tempering medium is realized in one coil of one channel and the return of this tempering medium in another coil of another channel.
  • There is also the possibility to supply both helix strands of one channel with inflowing tempering medium wherein even different tempering media, i.e., of different inconsistency and/or temperature and/or speed, can be supplied.
  • FIG. 9 shows that the inclination angle of the helix strands, which are both used for supplying the tempering medium, is continuously reduced in the flow direction. This means that the travel path of the tempering medium is longer, the residence time is increased, and the speed must be correspondingly increased so that an improved heat transfer is possible.
  • FIG. 10 shows a separating body 50 which at the same time has deflecting members as a unitary part thereof. They are arranged within a partial area of the channel at any desired location. In the second partial area the deflecting members with a continuously changing incline are provided.
  • the shown deflecting bodies 5 , 105 , 205 , 405 as well as the separating members can also have any desired other configuration. They can be inserted by retrofitting into the channels 1 , 101 , 201 , 301 , 401 , 501 , 601 . This facilitates mounting. Also, conventional rollers can be retrofitted in this way.
  • deflecting areas 7 , 107 , 207 , 407 impart rotation onto the medium, as has been explained in connection with the above embodiments. However, this makes it possible to introduce a uniform and predictable sequence of turbulent flows in the channel of the roller to be temperature-controlled (tempered).
  • the deflecting bodies 5 , 105 , 205 , 405 and/or the separating members can be shaped, depending on the employed medium, of different materials, for example, stainless steel or plastic material, inasmuch as corrosive media are being used.
