Definitions
- the invention relates to a device for aligning magnetizable particles in a pasty material with an alignment body with a wall comprising a front surface section and a rear surface section, the pasty material and the alignment body with its front surface section being movable first relative to each other, the alignment body also being within the Alignment body on the inside of the
- Front surface section arranged magnet unit which generates a periodically variable, acting on the pasty material magnetic field for aligning the agnetizable particles.
- the invention further relates to a method for aligning magnetizable particles in a pasty material.
- the use of steel fibers in concrete to reinforce it has been known for about 20 years.
- the steel fibers in the concrete are evenly distributed over their volume with random alignment.
- Those fibers, which are arranged obliquely or even parallel to the attacking force, contribute to this reinforcing effect only to a lesser extent or not at all.
- Compared to concrete bodies with randomly distributed steel fibers can therefore be reduced in a concrete body with steel fibers aligned in the desired manner, the dosage without. the specific load behavior of the concrete body deteriorates noticeably.
- the device consists of an alignment body designed as a hollow profile, which in turn consists of a non-magnetic material.
- the alignment body has a circular arc-shaped front surface section in cross section, which tapers in a straight line over two flank sections in the direction of a rear surface section.
- a rotatably mounted roller is arranged concentrically with the arc-shaped front surface section and has one or more, in particular three, permanent magnets arranged at a distance of 120 ° from one another on its outer peripheral surface.
- the gap is minimized between the inside of the front surface portion and the peripheral surface of the roller.
- the device i.e. the aligning body with a rotating roller moves transversely to its longitudinal axis through the concrete body or the pasty concrete containing the fibers to be aligned, relative to the stationary aligning body, the concrete bending the aligning body along the same
- a second, substantially smaller magnetic roller is arranged in the region of the transition from the front surface section to the flank section.
- the arrangement of the on the magnets present in the second roller and the ratio of the diameters of the two rollers to one another is selected such that the magnetic field of the first roller leading around the front surface section is shielded to a certain extent in the region of the second roller, ie in the direction of the fibers, so that the release of the aligned fibers at the desired position is improved.
- a disadvantage of the described device or the method carried out with this device is that only fibers can be aligned in the immediate vicinity of the device, so that fibers further away maintain their random alignment.
- the orientation of the fibers is not optimal due to the comparatively high residual field strength at the release position.
- a mere increase in the magnetic field strength through the use of stronger magnets would increase the range of the magnetic field to a limited extent, but would significantly reduce the quality of the layer structure as a result of poorer release of the aligned particles.
- the device should also be able to be implemented without great technical outlay and costs. Further objects of the invention result from the following description of the invention and the exemplary embodiments.
- the previously derived object is achieved with a device of the type mentioned in the introduction in that the magnetic field is divided into at least two zones with partial fields of different field strength and / or different field line course, the partial field of the first zone exerting a long-range attractive and aligning force on the particles and the subfield of the second zone releases the particles again in the aligned position.
- the division according to the invention of the magnetic field generated by the magnet unit into at least two zones with partial fields of different field strength and / or different field line course on the one hand ensures that the particles are also aligned which are at a comparatively large distance from the alignment body.
- the subfield of the second zone ensures that the particles are released again precisely in the intended position on the wall of the alignment body, which means, for example, that a layer to be formed from aligned particles in the pasty material has the desired properties, in particular a high fiber density the layer plane with the smallest possible layer thickness.
- the alignment body provided according to the invention can consist of any material.
- Non-magnetic materials are particularly suitable since they do not hinder the release of the aligned particles on the wall of the alignment body in the position provided for this due to their own magnetic field.
- its range can be adjusted by appropriate selection of the field strength and the field line course of the partial field in this zone.
- the proportion of the particles in the pasty material that are also to be aligned by the device according to the invention, or the proportion of the particles that are to remain in the material in a random orientation can be set exactly.
- the material properties of the pasty material such as its viscosity or the size and shape of other fillers contained therein, are also taken into account.
- the field line course in the magnet unit can be set in different ways.
- An advantageous setting is that the field lines of the magnetic field of the magnet unit run exclusively in one plane perpendicular to the relative movement between the alignment body and the pasty material. The particles are thus aligned exclusively in this plane. The consequence of this is that the particles can be released again particularly easily in the position provided on the wall of the alignment body, since there is no formation of a network of magnetized particles along the direction of the relative movement, which results in a strong cohesion between the magnetized particles causes and thus their release difficult.
- Another possibility for setting the field line course is that the field lines run in one plane parallel to the relative movement between the alignment body and the pasty material.
- this can be effectively countered by a particularly variable field line course.
- the partial field of the first zone exerting a long-range attractive force on the particles
- the second zone exerting a holding force on the particles, through which these are aligned and that the third zone releases the particles again in the aligned position.
- the alignment of particles located relatively far from the alignment body is still ensured, on the other hand these are particularly precisely aligned by the moderate holding force generated by the subfield of the second zone and finally by the subfield of the third zone after reaching it released the desired position in the pasty material.
- This division of the magnetic field consequently makes it possible that, despite the strong, long-range attraction of the subfield of the first zone, the quality of the particle alignment and its controlled release at the intended position is not impaired.
- the field line course of the magnetic field of the magnetic unit is combined from portions which run in a plane perpendicular to the relative movement between the alignment body and the pasty material and portions which run parallel to the relative movement.
- This type of combined field line course in particular enables the aligned particles are distributed particularly evenly in the target volume and no longer have any tendency to accumulate along such field lines which run exclusively parallel or perpendicular to the relative movement between the alignment body and the pasty material.
- the spatial and temporal continuity of the alignment process can also be achieved if the relative speed between the alignment body and the pasty material and the frequency of the periodically changing magnetic field are not optimally coordinated.
- the first and second zones can each cover approximately a 90 ° area and the third zone an approximately 180 "area of the cross section of the magnet unit.
- the three it is also expedient for the three to cover the cross section of the magnet unit by approximately 120 ° zones.
- the magnet unit generating the periodically changing magnetic field is designed as a rotating body with a static field distribution.
- the alignment body is advantageously designed as a hollow profile extending transversely to the direction of the relative movement between the alignment body and the pasty material, the cross section of which is like a Wing cross-section tapers from the substantially semicircularly curved front surface section tapering over two flank surfaces to the rear surface section.
- this shape favors the alignment of the particles during their transport along the curved and on the other hand their controlled release at the transition between one end of the front surface section and a flank surface.
- the design of the magnet unit as a rotating cylindrical roller, the axis of rotation of which coincides with the central axis of the semicircularly curved front surface section, ensures that the gap between the inside of the front surface section of the alignment body and the magnetic roller is minimal, so that its magnetic field is low-loss on the alignment body surrounding pasty material can act.
- the magnetic roller expediently extends over the entire length of the alignment body. Accordingly, the field lines lying in one plane parallel to the relative movement between the alignment body and the pasty material run in the axial direction of the magnetic roller, while the field lines lying in one plane parallel to the relative movement run in the circumferential direction the magnetic roller.
- the magnetic field formed from the three partial fields when this is generated by permanent magnets there is a high degree of variability in the formation of the magnetic field formed from the three partial fields when this is generated by permanent magnets.
- Particularly high field strengths can be generated with permanent magnets made of an NdFeB alloy.
- the function of the third zone of the magnetic field is to release the particles again in the aligned position. This can be achieved particularly effectively in that the subfield of the third zone is generated by a soft magnetic material, in particular a low-carbon steel. This leads to a backflow of the magnetic field lines that is spatially restricted to the soft magnetic material, with the result that radially outside this zone the field strength of the magnetic field almost disappears and the particles in this area experience practically no more attractive force.
- the object is achieved by a method using the device described above.
- the advantages of this device apply equally to the method according to the invention. This has a wide range of applications, in particular if. Concrete that is not set is used as a pasty material and the particles are formed as steel fibers.
- the particles can also be designed as steel rings.
- Their use proves to be particularly advantageous if, for example, a thin layer is to be produced in a concrete slab subjected to bending.
- steel rings a particularly high degree of overlap of the individual particles is achieved in the layer plane, which increases the effectiveness of the structural reinforcement. This enables, among other things compared to the use of conventional one-dimensionally shaped steel chips or fibers, a reduction in the use of materials without a noticeable deterioration in the load behavior of the reinforced component.

- FIG. 11 shows the magnet unit of FIG. 10 in cross section along the line XI-XI of FIG. 10 with the field line curve shown.
- the device has an alignment body 1 in the form of a hollow profile, which consists of a non-magnetic material.
- the hollow profile comprises an arc-shaped front surface section 1 a, which tapers in a straight line over two flank sections 1 c in the direction of a rear surface section 1 b.
- a magnet unit 2 which is designed as a rotatably mounted, cylindrical roller arranged concentrically with the circular-arc-shaped front surface section 1 a.
- the magnetic roller 2 is equipped with permanent magnets along its longitudinal axis and is set in rotation, for example, by one or more electric motors (not shown).
- a rotating, ie periodically changing, magnetic field acting on the particles contained in the pasty material generated which is divided into three zones I, II, III with sub-fields of different field strength and / or different field line course.
- the first and second zones each cover a 90 "region and the third zone the remaining 180 ° region of the circular cross section of the magnet unit.
- the radius of the magnet roller 2 is only slightly smaller than the radius of curvature of the front surface section la, so that the gap between the inside of the front surface section la and the circumferential surface of the magnetic roller 2 is minimal and the magnetic field of the magnetic roller 2 can act with little loss on the pasty material surrounding the alignment body 1.
- the magnet unit is arranged fixed in the alignment body and the periodically changing magnetic field is realized by an arrangement of individually controllable electromagnets within the alignment body.
- FIG. 2 The principle of operation of the device is shown schematically in FIG. 2. Accordingly, the alignment body 1 with the rotating magnetic roller 2 arranged therein is moved transversely to its longitudinal axis lf through a pasty material 3 in the form of a non-set concrete layer, which contains magnetizable particles 4 in the form of steel fibers or steel rings. Likewise, the pasty concrete 3 can be moved relative to the stationary alignment body 1. In both cases, the concrete 3 flows around the alignment body 1 along its curved front surface section la. The magnetic roller 2 rotates counterclockwise, so that the magnetizable particles 4 in the manner described below can be arranged in a layer 6 below the alignment body 1. As can easily be seen in FIG. 2, the field lines run in a plane parallel to the relative movement between the alignment body 1 and the pasty material 3.
- the partial field of the first zone I exerts a long-range attractive force on the steel fibers 4, so that the fibers 4 move in an elongated area 7 in front of the front surface section 1 a of the alignment body 1.
- the partial field of the second zone II exerts a holding force on the attracted particles 4, by means of which they are transported downward along the front surface section la in accordance with the direction of rotation of the magnetic roller 2 and thereby aligned.
- the partial field of the third zone III the field strength of which virtually disappears radially outside the alignment body 1 within this zone due to the closed magnetic field lines, releases the particles 4 in the aligned position approximately at the point le of the transition of the circularly curved front surface section la into the lower flank section lc ,
- the rotation of the total magnetic field of the magnetic roller 2 composed of the three partial fields means that the partial field of the first zone I on the. Point of release of the particles 4 acts. Accordingly, the detachment of the particles from the wall of the alignment body 1 is regularly difficult for a short time, which would lead to an undesired undulating structure of the particle layer ⁇ to be formed. However, this can be effectively countered by making the rotation frequency of the magnetic roller very high relative to the movement of the alignment body 1 in the concrete layer is, whereby a possible wave structure of the layer 6 is smoothed.
- a strong permanent magnet 8 preferably made of an NdFeB alloy, extends radially outward from a point near the axis of rotation of the magnetic roller 2. Its outer end face 8a, on which the magnetic north pole is located, is shaped in accordance with the curvature of the magnetic roller, so that the magnetic roller can rotate with a minimal gap to the inner surface of the front surface section la of the alignment body 1.
- a pole shoe 9 made of a soft magnetic material is inside the magnetic roller 2; preferably a soft unalloyed steel.
- the pole piece 9 comprises a central section 9a which is flush with the inner end face of the permanent magnet 8, on which its magnetic south pole is located, and surrounds the axis of rotation of the magnetic roller 2.
- An end section 9b projects from the central section 9a on both sides. Both end sections 9b are slightly angled in the direction of the permanent magnet 8 and extend to the outer circumference of the magnetic roller 2, their respective outer end faces 9c also being adapted to the circumferential curvature of the magnetic roller.
- the magnetic field generated by this magnet arrangement is divided into two zones I, II and is graphically represented by its field lines.
- the first zone I is formed by the permanent magnet 8 and the pole piece 9.
- the pole piece 9 is due to the strong permanent magnet 8 agnetizes, so that a magnetic south pole is formed at each of its end sections 9b.
- the field lines run from the north pole of the permanent magnet 8 through the space surrounding the magnet roller or the aligning body enclosing it to the end sections 9b of the pole piece 9, with the result that the region 10 of the magnet roller which is rearward with respect to the magnet arrangement and which forms the second zone II forms and can be filled with aluminum or steel, for example, is interspersed with a field of only low field strength.
- the field generated by the north pole of the permanent magnet 8 exerts an attractive force, in particular on agnetizable material, which is located in an area in the extension of its longitudinal axis.
- the magnet arrangement of FIG. 3 is characterized in particular by low manufacturing effort and thus low costs.
- the magnet arrangement according to FIG. 4 comprises two permanent magnets 11, 12 which extend radially outward from the axis of rotation of the magnetic roller 2 and which have essentially the same size and strength.
- Both magnets 11, 12 are preferably made of an NdFeB alloy.
- the magnets 11, 12 are at an acute angle of approximately 60 ° to one another and extend approximately from the axis of rotation of the magnetic roller 2 to their circumferential surface, the outer end faces of the magnets 11, 12 in turn being adapted to the circumferential curvature of the magnetic roller 2 by the gap between To minimize the magnetic roller and front surface section of the alignment body (not shown here).
- Both magnets 11, 12 are oriented in opposite directions, so that in the case of the first magnet 11 the north pole points outwards and in the case of the second magnet 12 the south pole.
- an area 13 made of a soft magnetic material, preferably a soft unalloyed steel, which extends over 180 ° and thus over half the cross-sectional area of the magnetic roller 2.
- the magnetic field generated by this magnet arrangement is in turn divided into two zones I, II and is visualized by its field line course.
- the partial field of the first zone is generated by the angularly arranged magnets 11, 12. Their opposite orientation creates a magnetic field that projects deep into the room and thus exerts a far-reaching attraction.
- the residual field strength in the area surrounding the second zone is negligible, which is a prerequisite for the attracted and aligned particles to be released again at the desired location.
- a magnetic field divided into three zones I *, II *, III * is generated by the asymmetrical magnet arrangement of the magnetic roller 2 shown in FIG. 5 (see FIG. 5b).
- the order of the arrangement of zones I *, II *, III * is reversed. Consequently, the magnetic roller 2 of FIG. 5 rotates clockwise during operation and the particles 4 to be aligned are arranged above the alignment body 1 in the pasty material 3.
- the magnetic roller 2 itself is divided into two 180 "sectors 14, 15 with a central cutting surface D.
- the sector 14 is in turn divided into two 90" sectors 14a, 14b.
- a strong permanent magnet 16 is arranged in the sector 14a and extends at right angles from the cut surface D in the direction of the opposite peripheral surface of the magnetic roller 2, so that its north pole is located in the region of the peripheral surface of the magnetic roller 2.
- a second weaker permanent magnet 17 is arranged parallel to the first magnet 16, but oriented in the opposite direction.
- Both magnets 16, 17 preferably consist of an NdFeB alloy and are adapted with respect to their outer end faces to the curvature of the peripheral surface of the magnetic roller 2.
- the spaces between the magnets 16, 17 are filled with a non-magnetic material, such as aluminum.
- the second 180 "sector 15 consists entirely of a soft magnetic material, preferably a soft unalloyed steel.
- the partial field generated by the strong magnet 16 in the first zone I * exerts a particularly long-range attraction force on the magnetizable particles, which are contained in the material surrounding the magnetic roller 2 or the alignment body 1.
- the partial field of the second zone II * is weaker than that of the first zone I *, but is therefore preferably suitable for transporting the particles attracted by the magnetic field of the first zone I * to the release position and thereby aligning them in the desired manner.
- the soft magnetic material of the sector 15 ensures that the returning field lines of the poles Magnets 16, 17 are almost completely enclosed in the partial field of the third zone III *, so that practically no force acts on the particles outside and they can thus be easily released in the aligned position.
- the magnets 16, 17 are spatially connected by a further transversely arranged magnet 19, the north pole of this magnet 19 pointing towards the strong magnet 16 of the first zone I *.
- the range of the partial field of the first zone I * can be increased even further, so that magnetizable particles can be attracted from an even greater distance.
- FIG. 7 is also based on the asymmetrical magnet arrangement of FIG. 5.
- two further transversely arranged magnets 20, 21 are provided in the 180 "sector 14 abut the respective outer longitudinal sides of the magnets 16, 17 and are oriented such that the strong magnet 16 faces the north pole and the weaker magnet 17 the south pole, which is a total of five magnets 16, 17, 19, 20, 21 existing arrangement corresponds to that of a linear Halbach ' Arrays.
- the arrangement with a bucking pole or with a Halbach array can also be implemented in the two-pole arrangement with radial magnetic alignment, for example according to FIG. 4, and improves its effect in relation to the attraction and alignment of the magnetizable particles.
- the magnetic roller 2 * is equipped with a number of permanent magnets 22a-22e arranged one behind the other in the axial direction of the roller 2 *, preferably made of NdFeB.
- the block-shaped magnets 22a-22e which can be produced particularly cost-effectively, in turn form a linear Halbach array which, in this exemplary embodiment, is oriented in the axial direction of the magnetic roller 2 * in contrast to those described above. Accordingly, the field lines run strictly in the axial direction of the roller 2 *, that is to say in a plane perpendicular to the relative movement between the alignment body 1 and the pasty material 3 (see FIG. 2).
- a magnetic field consisting of two zones I **, II ** is formed by the magnetic roller according to FIG. 8, in which the partial field of the first zone I ** exerts a long-range force on the particles present in the pasty material and the vanishing one subfield the second zone n ** releases the particles again approximately at position le of the alignment body.
- the magnets 22a-22e are fastened on a roller block 23 with a semicircular cross section.
- the roller block 23 preferably consists of a magnetic, high-permeability steel.
- the particular advantage of this axial arrangement of the magnets is that, due to the axial course of the magnetic field lines (see FIG. 9), they do not scatter in the circumferential direction of the magnetic roller, i.e. the magnetic field is strictly limited in the circumferential direction. As a result, there is no network formation under the magnetized particles in the circumferential direction of the magnetic roller, which regularly makes it more difficult to detach the aligned particles. Furthermore, the axial field line course results in a particularly extensive zone in which the magnetic field disappears, which in turn facilitates the release of the aligned particles.
- FIGS. 10 and 11 another embodiment of the invention is shown in FIGS. 10 and 11.
- the magnetic roller 2 ** is equipped in a recurring order with permanent magnets 24a, 24b, 25 preferably made of NdFeB in such a way that along the longitudinal axis of the magnet unit there are two magnets 24a, 24b arranged next to one another, symmetrically to the longitudinal axis, with an identical orientation with one Alternate stronger, central magnets 25 with opposite orientations.
- the magnets 24a, 24b, 25 are in turn fastened on a roller block 26 with a semicircular cross section.
- the roller block 23 preferably consists of a magnetic steel with high permeability.
- FIG. 11 shows the field line course of the magnet unit 2 ** according to the invention projected onto the viewing plane.
- the field lines run from the north pole of the central magnet 25 to the south poles of the magnets 24a, 24b arranged next to one another and offset from the magnet 25.
- the field lines have portions oriented perpendicular to the longitudinal axis of the magnet unit 2 ** and thus run in a plane parallel to the relative movement between the alignment body and the pasty material.
- they also have portions running in the axial direction, as a result of which the axial offset between the magnet pairs 24a, 24b and the central magnet 25 is bridged.
- the particular advantage of such a magnet arrangement is that the aligned particles are distributed particularly evenly in the target volume and no longer have any tendency to accumulate along field lines running exclusively parallel or perpendicular to the relative movement between the alignment body and the pasty material.
