Definitions

  • a dispersion apparatus such as a media agitating mill or the like accommodates a lot of granular media in a cylinder, and milled base ink, being rough ink, is injected, and is agitated together with the granular media by agitating members such as pins installed on a rotating shaft, discs, or the like, for dispersion mixing.
  • the granular media agitated and dispersed in the cylinder crush and refine milled base ink, thus dispersion and milling proceed, so that there is an advantage that the productivity is high.
  • the vertical cylinder type has a high load in its axis of rotation in a dispersion process of base ink with comparatively high viscosity when the apparatus is started, and the dispersion efficiency of milled base ink drops due to congestion of granular media, and a phenomenon called choking occurs in which granular media accumulates in the vicinity of the ink discharge side, so that there is a deficiency that stable operation is not possible.
  • An example of such a horizontal cylinder type is a media agitating type mill disclosed in a Japanese Unexamined Patent Application, First Publication No. 9-225279 .
  • rotors in a cylinder and agitating members, which protrude from the rotors radially, are positioned at a predetermined spacing in the longitudinal direction of the rotors, and when performing dispersion processing by agitating the process material injected into the cylinder together with media, a ratio D1/D2 between an outside diameter D1 of the rotors installed in the cylinder and an inside diameter D2 of the cylinder is set to be in a range of 0.4 to 0.7.
  • a cooling device may be provided in the rotor, and furthermore a cooling device may be provided outside the cylinder, which prevents the physical properties of the process material from changing by temperature increase, and it is especially useful for process material whose nature changes easily with temperature, such as gravure ink and the like.
  • a ratio with the outside diameter D1 of the rotors, D1/P may be set in a range of 1.4 to 3.0, and this enables the dispersion processing of the process material to proceed more reliably.
  • a dispersion apparatus 10 in the embodiment as shown in FIG. 1 and FIG. 2 is a media agitating mill or the like, for example, which has an approximately cylindrically shaped cylinder 11, an inlet 12 for slurry (process material) such as ink and the like, for example, formed on one end plate 11a of the cylinder 11, and an outlet 13 for discharging slurry that has been injected into the cylinder 11, dispersed and milled, formed on the other end plate 11b opposite the end plate 11a.
  • a separator 14 is fitted over an aperture 13a leading to the cylinder 11 via a gap C, and dispersed and milled slurry is discharged through the gap C between the separator 14 and the aperture 13a.
  • the gap C does not allow media loaded in the cylinder 11 to pass through, for example granular shaped beads 22, but it is designed to pass small diameter slurry.
  • a plurality of agitating discs 18 (agitating members) and a plurality of rotors 19 are fitted alternately and coaxially, via a ring-shaped spacer 17 from the separator 14 side, on the main shaft 15.
  • FIG. 3 shows one example of a case where the agitating members are agitating discs.
  • agitating discs 18 appear approximately disc shaped with a larger outside diameter than the rotors 19 as shown in this figure.
  • a plurality (4 in the figure) of slots 21 are provided in the agitating disc 18 around its outer periphery at a predetermined spacing in the circumferential direction.
  • the slots 21 curve inward from the outer peripheral surface toward the center extending forward in the direction of rotation.
  • the slots 21 are formed such that the width in the circumferential direction is larger than the outside diameter of the beads 22, which allows the beads 22to pass through.
  • through holes 23 are punched between adjacent slots 21 in the agitating discs 18 at a predetermined spacing in the circumferential direction, close to the rotor 19.
  • the beads 22 can also pass through the through holes 23, which enables a large number of beads 22 gathered on the outlet 13 side of the cylinder 11 to pass through and move to the inlet 12 side.
  • agitating discs 18 are fitted on both ends.
  • the construction may be such that rotors 19 are fitted on both ends.
  • the agitating discs 18 and the rotors 19 may be arranged alternately, or the agitating discs 18 may be arranged on a rotor 19 formed as a long shaft, at a predetermined spacing.
  • the space between the internal circumference surface 11c of the cylinder 11, and the agitating discs 18 and the rotors 19 forms a crushing chamber 24 (milling zone) into which the beads 22 and slurry are loaded.
  • a large number of granular beads 22 is held in the cylinder, and the beads 22 which are scattered to the inner surface 11c of the cylinder 11 by the rotation of the rotors 19 and the agitating discs 18, collide with injected slurry and accumulated beads 22, and crush and disperse the slurry, which is sent toward the outlet 13 side continuously as it repeats.
  • the beads 22 appear almost spherical for example, and their average particle size is set to about 0.2 to 3mm. Furthermore, the beads 22 fill up approximately 65 to 95% of the volume of the cylinder 11, and the filling percentage is determined appropriately depending on the nature of the slurry including pigment and the like to be crushed, for example how easy it is to crush, or the particle size before crushing and the like. Furthermore, the material of the beads 22 used is selected depending on the properties of the slurry, for example viscosity, specific gravity, required grain size for pulverization and dispersion, and the like, and for example, glass beads, zircon beads, zirconia beads, steel balls or the like are used. However, in general, material that has high specific gravity and is difficult to abrade is preferable. If the viscosity of slurry, such as ink, is high, beads 22 with high specific gravity are selected.
  • steel beads generally generate black iron powder by collision, friction, and the like, it is used for India ink type ink, and the like, while in the case of whitish ink, beads such as zirconia are used. In the case of slurry with low viscosity, glass beads are used typically.
  • beads 22 having a particle size five to six times the initial particle size of the injected slurry may be used.
  • dispersion processing of slurry there are both a case where it is processed to the required particle size by a single stage dispersion apparatus, and a case where it is passed through a plurality of processing stages using a plurality of dispersion apparatuses in which beads with different particle sizes are loaded, and it is dispersed to the required particle size gradually.
  • the ratio of the two D1/D2 is set in a range of 0.4 to 0.7. If the ratio D1/D2 is set in this range, the peripheral speed of the outer periphery of the rotors 19 can be set high, and furthermore the distance to the internal circumference surface 11c of the cylinder can be set short. Hence, loss of the kinetic energy for scattering the beads 22 is low, thus enabling efficient crushing and dispersion of slurry.
  • the ratio D1/P with the outside diameter D1 of the rotors 19 is set in a range of 1.4 to 3.0. If the ratio D1/P is set in this range, motion of the beads 22 in the cylinder 11 can be maintained satisfactorily, so that it is possible to prevent drift and a phenomenon of choking of the beads 22 due to the velocity of the injected slurry. If it is 1.4 or more, then the spacing between the agitating discs 18 is not too large, which prevents the motion of media from deteriorating, thus enabling the process material to be crushed and dispersed sufficiently. Moreover, if it is 3.0 or less, then the spacing between the agitating discs 18 is not too narrow, so that uneven distribution and drift of the media (beads 22) is prevented, thus enabling stable operation.
  • the array pitch P of the agitating members does not always need to be a fixed spacing, and the spacing may be changed depending on the nature of the process material. For example, if it narrows from the inlet 12 toward the outlet 13, it is possible to intensify the dispersion force gradually.
  • a dispersion apparatus 10 according to the present embodiment has the above-described structure. Next is a description of a dispersion method.
  • the beads 22 are loaded in advance into the crushing chamber 24 defined by the cylinder internal circumference surface 11c, the agitating discs 18, and the rotors 19 in the cylinder 11.
  • Slurry is supplied from the inlet 12 to the cylinder 11 continuously, and at the same time by rotating the main shaft 15, which is linked to a drive source (not shown in the figure), at a predetermined speed, the agitating discs 18 and the rotors 19 rotate in unison.
  • the speed of the outer periphery of the agitating discs 18 is approximately 7 to 18m/s and preferably approximately 10 to 15m/s.
  • the slurry is agitated together with the beads 22 and dispersed.
  • the beads 22 are scattered to the internal circumference surface 11c of the cylinder 11 by the agitating discs 12, collide with the slurry and beads 22 accumulating around the internal circumference surface 11c, and crush and refine the slurry particles.
  • the rotors 19 rotating in unison with the discs 18 have large diameters, so the peripheral speed of the outer peripheral surface is high.
  • the beads 22 and the slurry accumulating around the outer periphery of the rotors 19 fly toward the cylinder internal circumference surface 11c by centrifugal force.
  • the ratio D1/D2 is small, being 0.3 or less, the distance to travel to the cylinder internal circumference surface is long, and also the kinetic energy loss is high due to the viscoelasticity of slurry which collides while traveling. Especially in the case where the slurry has high viscosity characteristics, the energy loss is high. Furthermore, if the periphery of the internal circumference surface 11c of the cylinder 11 is cooled by the external cooling path 20, the viscosity of the slurry in this region becomes high, thus causing the energy loss to increase further.
  • the ratio D1/D2 is large, being 0.4 or more, the cross section (capacity) of the crushing chamber 24 is reduced, but the kinetic energy of the beads 22, which are scattered by high speed because of the short distance to the cylinder internal circumference surface 11c, work the slurry, which has comparatively high viscosity, around the cylinder internal circumference surface 11c sufficiently to crush it, so that energy loss can be avoided.
  • the beads 22 and the slurry in the crushing chamber 24 of the cylinder Ware sent to the outlet 13 side gradually by the supply pressure of the slurry supplied continuously from the inlet 12.
  • a gap C between the separator 14 and the aperture 13a of the outlet 13 prevents the beads 22 from passing through, but lets atomized slurry pass through, so that only dispersed slurry is discharged from the outlet 13 and recovered.
  • the beads 22 left in the vicinity of the outlet 13 accumulate between the agitating disc 18 on the outlet 13 side and the other end face 11b of the cylinder as shown in FIG. 1 and FIG. 2, but are returned to the inlet 12 side through through holes 23 in this agitating disc 18.
  • the agitating disc 18 close to the outlet 13 is fitted slightly off the center of the rotor 19, it is easy to scatter the beads 22, which enables the degree of recirculation of the beads 22 to be increased.
  • the beads 22 are normally in an overfilled state, but if the separator 14 is positioned off the center of the rotor 19, the effect of scattering the beads 22 increases, which enables the recirculation of the beads to be further increased.
  • the cross section of the crushing chamber 24 is reduced by about 20 to 30% from a conventional dispersion apparatus.
  • the outside diameter of the rotors 19 is increased, and the peripheral speed can be improved by two or more times, so that dispersion processing efficiency in the cylinder 11 is increased, and the residence time of the slurry is shortened.
  • the dispersion efficiency is good, better processing quality can be obtained than with a conventional dispersion apparatus.
  • the internal pressure of the cylinder increases and is converted into thermal energy, which sometimes affects the physical properties of slurry.
  • the increase of the internal pressure is only in the range of 0 to 0.01MPa with a normal feed rate in the range of 100 to 300kg/h, and hence no problem occurs.
  • the increase of the internal temperature can be suppressed by cooling by the internal cooling path 16 in the rotors 19 as well as by cooling by the external cooling path 20 of the cylinder 11.
  • a dispersion apparatus as shown in FIG. 8 has almost the same structure as the first embodiment, so the same symbols are used for the same parts, and descriptions are omitted.
  • a plurality of agitating discs 18 is fitted on a main shaft 31 installed in a cylinder 11 at a predetermined spacing, and cylindrical collar rings 32 are mounted on the outer peripheral surface of the main shaft 31 as rotors between adjacent agitating discs 18.
  • the outer peripheral surface of the collar rings 32 has the same outside diameter D1 as the outer peripheral surfaces of the rotors 19, and the numerical ranges of ratios D1/D2 and D1/P are the same as in the first embodiment.
  • the collar rings 32 and the agitating discs 18 rotate in unison with the main shaft 31.
  • the agitating discs 18 are basically fitted coaxially on main shafts 15 and 31, but they are not always coaxial, and may be fitted off center.
  • the agitating discs 18 and the rotors 19 or the collar rings 32 are not limited to separate pieces, and they may be constructed as one piece.
  • the main shafts 15 and 31 may also be constructed as one piece, or may be separate pieces
  • printing ink is used as the process material.
  • the present invention is not limited to this, and it may be used for a range of slurries or process liquids, such as can coatings, metal and automotive coatings, batteries and magnetic coatings, pulp and the like.
  • Examples 1, 2, 3, 4, 5, 6, 7 and 8 and Comparative Examples 1, 2, 3, 4, 5, 6 and 8 have the same structure as the dispersion apparatus 10 according to the first embodiment, and the outside diameters D1 of the rotors 19 vary as shown in Table 1 and Table 2 following.
