Description

  The present invention relates to a dispersion apparatus for dispersing a flowable material and a powder material.

  In recent years, lithium ion secondary batteries have been applied to hybrid vehicles and electric vehicles. An electrode of a lithium ion secondary battery is formed by applying a slurry of an active material to a base material such as an aluminum foil and baking it. This manufacturing method is described in, for example, Japanese Patent Application Laid-Open No. 2010-033786 (Patent Document 1).

  The slurry of the active material is made by mixing and dispersing the active material powder in a liquid. As an apparatus for dispersing the liquid and powder, Japanese Utility Model Publication No. 61-40337 (Patent Document 2), Japanese Utility Model Publication No. 4-50128 (Patent Document 3) and Japanese Patent Application Laid-Open No. 2006-849 (Patent Document 4) are disclosed. The described apparatus can be applied.

  In these, stators having convex teeth and rotors having convex teeth are alternately arranged in the flow direction of the slurry. In Patent Document 2, the convex teeth of the stator and the convex teeth of the rotor are formed so as to protrude in the axial direction. In Patent Documents 3 and 4, the convex teeth of the stator and the convex teeth of the rotor protrude in the radial direction. It is formed to do.

  By the way, since the powder mixed with the slurry of the active material described above is a metal, it is necessary to increase the surface hardness of the convex teeth of the stator and rotor to be dispersed, and coating may be applied. However, in Patent Document 2, the gap between adjacent convex teeth is formed equally from the tooth tip side to the tooth base side. Also in Patent Documents 3 and 4, the gaps in the members having convex teeth protruding radially inward are formed equally from the tooth tip side to the tooth base side. This makes it difficult to reliably apply the coating near the tooth base. In the case where the coating cannot be reliably applied, the durability may be lowered in addition to the reduction of the dispersion ability. In Patent Documents 3 and 4, the gaps in the convex teeth protruding outward in the radial direction are formed so as to widen from the tooth base side toward the tooth tip side. The gaps in the convex teeth protruding in the same way are the same from the tooth base side to the tooth tip side.

( 7 ) Further, the dispersing device is rotatably arranged in the flow path of the flowable material, can filter the flowable material, and has a plurality of through holes larger than the through holes of the powder filtering member. A formed fluid material filtering member may be provided.

  (Claim 1) According to the present invention, both the first convex tooth and the second convex tooth are formed so that a gap is widened from the tooth base side toward the tooth tip side. Therefore, when coating the first convex teeth and the second convex teeth, the coating can be reliably applied to the tooth base sides of both. Even when the metal powder is dispersed, sufficient dispersion capacity and durability can be secured. In addition, although stress is concentrated in the vicinity of the tooth root, if the hardness can be increased by coating, sufficient durability can be ensured even if high stress is applied. Furthermore, even if only one of the first convex teeth and the second convex teeth can be increased in hardness, as a whole dispersion device, if the other convex teeth are low in hardness, the other convex teeth Dispersion capacity and durability are determined. However, according to the present invention, since both the first convex teeth and the second convex teeth can be reliably coated, the dispersion ability and the durability can be reliably increased. Furthermore, since the circumferential edge surfaces of the first convex teeth and the second convex teeth are inclined, the dispersion ability and durability can be easily adjusted by changing the inclination angle.

Further, one of the first and second annular dispersion members is rotated integrally with the rotary blade. At this time, as the rotating blade rotates at a higher speed, it exerts a force for sending the fluid material from the radially inner side to the radially outer side. The higher the flow rate of the flowable material, the higher the dispersion capacity. On the other hand, the higher the peripheral speed of one of the first and second annular dispersion members (the higher the speed), the higher the dispersion ability. Therefore, when one of the rotating blades and the first and second annular dispersion members is rotated at a high speed, the dispersion ability is rapidly increased. On the other hand, when one of the rotating blade and the first and second annular dispersion members is rotated at a low speed, the dispersion ability is rapidly lowered. Thus, it is not easy to adjust the dispersion capacity.

  Therefore, by arranging one of the first and second annular dispersion members at different positions in the axial direction with respect to the rotary blade, it is possible to freely adjust one radial position of the first and second annular dispersion members. it can. That is, one peripheral speed of the first and second annular dispersion members can be freely adjusted without reducing the rotational speed of the rotary blades. Therefore, it is possible to freely adjust the dispersion capacity while sufficiently securing the flow rate of the fluid material.

( Claim 2 ) When the first convex teeth and the second convex teeth are formed so as to protrude in the axial direction, by adjusting the axial relative position of the first convex teeth and the second convex teeth, The range which opposes the radial direction of a 1st convex tooth and a 2nd convex tooth can be adjusted. Accordingly, it is possible to easily adjust the dispersion ability of the first and second convex teeth.

( Claims 3 and 4 ) By forming the first convex teeth and the second convex teeth so as to protrude in the radial direction, the above effect can be achieved while shortening the flow path of the fluid material. By shortening the flow path of the flowable material, an increase in pipe loss can be suppressed and the dispersion efficiency can be increased.

Furthermore, the fluid material that has circulated to the position of the first convex teeth passes between the first convex teeth adjacent in the circumferential direction and through the through holes formed in the first convex teeth. It mainly passes through the gap between the tooth tip sides where the gap width between the first convex teeth adjacent in the circumferential direction is wide and the through hole formed on the tooth tip side of the first convex tooth. The same applies to the second convex teeth. And since the direction which the 1st convex tooth and the 2nd convex tooth protrude is an opposite direction, fluid material receives a shearing force reliably by the 1st convex tooth and the 2nd convex tooth. Therefore, the fluid material can be reliably dispersed and homogenized.

( Claim 5 ) By providing the powder filtering member, the powder material flowing from the powder side region to the mixing region has a size capable of passing through the through hole of the powder filtering member. Therefore, it is possible to prevent the lump of the powder material from being generated in the mixing region, and to homogenize the fluid material mixed with the powder material.

( Claim 6 ) By providing the powder dispersion member, when the powder material cannot pass through the through-hole of the powder filtration member, the powder is dispersed by the powder filtration member and the powder dispersion member in the powder side region. The material can be dispersed. Therefore, the dispersed powder material can pass through the through hole of the powder filtering member and is mixed with the fluid material.

( Claim 7 ) By filtering the fluid material with the fluid material filtering member, the powder material mixed with the fluid material can be further dispersed. Thereby, homogenization of a fluid material can be achieved.

<First embodiment>
The mixing and dispersing apparatus of the present embodiment constitutes an apparatus for manufacturing electrodes (positive electrode and negative electrode) of a lithium ion secondary battery, for example. An electrode of a lithium ion secondary battery is formed by applying a slurry of an active material to a base material such as an aluminum foil or a copper foil and baking it. The mixing and dispersing apparatus of this embodiment is an apparatus for producing a slurry of active material. Specifically, it is made by mixing and dispersing a metal powder of an active material in a liquid such as water. Hereinafter, the slurry after the powder material is mixed and dispersed is referred to as a flowable mixed material, and the liquid before the powder material is mixed is referred to as a flowable base material. Both the flowable mixed material and the flowable base material have flowability. However, the fluid mixed material is formed with a higher viscosity than the fluid base material.

  The mixing and dispersing apparatus of the present embodiment will be described with reference to FIGS. The mixing / dispersing device sucks the flowable base material into the housing 110 from the lower side of FIG. 1, and sucks the powder material into the housing 110 from the upper side of FIG. 1. The material is mixed and dispersed to produce a fluid mixed material. And the produced | generated fluid mixed material is discharged | emitted from the outer peripheral surface of the housing 110 to radial direction outward.

As shown in FIG. 1, the mixing and dispersing apparatus includes an apparatus main body 100, a powder hopper 20 that stores a powder material of an active material, and a drive motor 40. Here, the powder hopper 20 and the drive motor 40 are supported by the housing 110 of the apparatus main body 100.
The apparatus main body 100 includes a housing 110, a partition plate 120, a rotating blade 130, a guide member 140, a first annular dispersion member 150, and a second annular dispersion member 160.

  The housing 110 is formed in a hollow disk shape. In the center of the lower surface of the housing 110, a fluid material suction port 111 for sucking a fluid base material is formed. Near the center of the upper surface of the housing 110, a powder material discharge end of the powder hopper 20 can be mounted, and a powder suction port 112 for sucking the powder material from the powder hopper 20 is formed. . In the housing 110, the fluid base material sucked from the fluid material suction port 111 and the powder material sucked from the powder suction port 112 are mixed and dispersed to generate a fluid mixture material. To do. Further, a discharge port 113 for discharging the fluid mixed material generated in the housing 110 is formed in a part of the outer peripheral surface of the housing 110.

  The partition plate 120 is formed in a disk shape, and the center portion thereof is fixed to the end portion of the rotation shaft of the drive motor 40. The partition plate 120 is disposed in the housing 110 so as to be rotatable around its central axis. The partition plate 120 divides the vicinity of the center in the housing 110 into upper and lower parts, and the lower part of the fluid material suction port 111 side area E1 (fluid material side area) and the upper part powder suction. It is partitioned into a region E2 (powder side region) on the mouth 112 side. The drive motor 40 is fixed to the upper surface side of the apparatus main body 100.

  A plurality of rotating blades 130 are provided in the circumferential direction at radially outer positions on the lower surface of the partition plate 120. That is, the rotary blade 130 rotates as the partition plate 120 rotates. The rotary vane 130 functions as a pump vane that sends out the fluid base material sucked from the fluid material suction port 111 located radially inwardly outward. Each rotary blade 130 is formed so that the phase is shifted in the direction opposite to the rotation direction of the rotary blade 130 as it goes radially outward. In FIG. 2, since the rotation direction of the rotary blades 130 is clockwise, the phase of each rotary blade 130 is shifted to the counterclockwise side as going outward in the radial direction.

  The guide member 140 is disposed radially outward of the partition plate 120 (on the downstream side of the partition plate 120 and the rotary blade 130), and is fixed to the housing 110. The guide member 140 has a flow passage 141 for flowable material that further increases the flow rate of the flowable base material fed from the rotary blade 130 toward the mixing region radially outward. The fluidity material guide passage 141 is formed so that the phase is shifted in the rotation direction of the rotary blade 130 as it goes outward in the radial direction. That is, the rotating blade 130 and the flowable material guide passage 141 of the guide member 140 function as a so-called diffuser pump. The flowable material guide passage 141 is formed so that the cross-sectional area of the flow passage becomes smaller toward the outer side in the radial direction. By reducing the flow path cross-sectional area of the fluidity material guide passage 141 toward the downstream side, the fluidity base material can be further increased in speed.

  Further, the guide member 140 has a powder guide passage 142 that guides the powder material in the powder side region E2 toward the mixing region located radially outward. The powder guide passage 142 is formed at least inward in the radial direction, independently of the flowable material guide passage 141 via the partition portion 143. However, the radially outward direction of the powder guide passage 142 communicates with the radially outward direction of the flowable material guide passage 141. That is, the powder material in the powder side region E2 is mixed through the powder guide passage 142 with the flow of the fluid base material in the mixing region positioned radially outward of the fluid material guide passage 141. You can be guided to the area.

  The powder guide passage 142 is formed to extend in the same direction as the flowable material guide passage 141, and is formed so that the phase is shifted in the rotation direction of the rotary blade 130 as it goes outward in the radial direction. ing. Furthermore, the powder guide passage 142 is formed so that the cross-sectional area of the flow path decreases as it goes outward in the radial direction. By forming the flowable material guide passage 141 and the powder guide passage 142 in this manner, the powder material in the powder side region E2 can be more effectively guided to the mixing region. Furthermore, by reducing the flow passage cross-sectional area of the powder guide passage toward the downstream, the powder material can be more easily guided to the mixing region.

  The first annular dispersion member 150 is formed in an annular shape having a through hole at the center, and is integrally connected to the lower edge of the rotary blade 130. The first annular dispersion member 150 includes a disk portion 151, first inner peripheral convex teeth 152, and first outer peripheral convex teeth 153. The disk portion 151 is connected to the lower edge of the rotary blade 130, and the center hole thereof communicates with the fluid material suction port 111. The first inner peripheral convex teeth 152 are arranged in a mixing region that is radially outward of the guide member 140 (downstream of the guide member 140), and axially upward (flowable mixed material) from the upper surface of the disk portion 151. Are formed in the circumferential direction so as to project in the circumferential direction. A plurality of first outer peripheral convex teeth 153 are formed radially outwardly of the first inner peripheral convex teeth 152 and projecting upward in the axial direction from the outer peripheral edge of the disk portion 151, and are formed in the circumferential direction. Yes.

  The first inner peripheral convex teeth 152 are formed as shown in FIG. That is, the circumferential edge surface of the first inner circumferential convex tooth 152 extends from the root side to the tooth tip side of the first inner circumferential convex tooth 152 adjacent in the circumferential direction in the entire length in the protruding direction (full axial length). The gap is formed so as to be wide. The first outer peripheral convex teeth 153 are formed in the same shape as the first inner peripheral convex teeth 152. These convex teeth 152 and 153 are formed into triangular teeth, sin-shaped teeth, trapezoidal teeth, or the like. That is, the first inner peripheral convex teeth 152 and the first outer peripheral convex teeth 153 have a tapered tip portion in the upper axial direction, and are formed in a comb shape that is continuous in the circumferential direction. The surfaces of the first inner peripheral convex teeth 152 and the first outer peripheral convex teeth 153 are coated with, for example, a diamond-like carbon (DLC) film to increase the hardness.

  The tips of the first inner peripheral convex teeth 152 and the first outer peripheral convex teeth 153 have a slight gap so as to be rotatable relative to the inner surface of the housing 110. The circumferential edges of the first inner peripheral convex teeth 152 and the first outer peripheral convex teeth 153 are tooth tips of the first inner peripheral convex teeth 152 and the first outer peripheral convex teeth 153 that are adjacent in the circumferential direction, respectively. The gap width on the side is substantially the same as the gap width on the tooth base side.

  The second annular dispersion member 160 disperses the fluid mixed material by a relative operation with the first annular dispersion member 150. The second annular dispersion member 160 is fixed to the inner surface of the housing 110 and includes a second inner peripheral convex tooth 161 and a second outer peripheral convex tooth 162. The second inner peripheral convex teeth 161 and the second outer peripheral convex teeth 162 protrude from the inner surface of the housing 110 downward in the axial direction (the direction opposite to the protruding direction of the first inner peripheral convex teeth 152), and A plurality are formed in the circumferential direction.

  The second inner peripheral convex teeth 161 are formed as shown in FIG. That is, the circumferential edge surface of the second inner circumferential convex tooth 161 is directed from the tooth root side to the tooth tip side of the second inner circumferential convex tooth 161 adjacent in the circumferential direction in the entire length in the protruding direction (full axial length). The gap is formed so as to be wide. The second outer peripheral convex teeth 162 are formed in the same shape as the second inner peripheral convex teeth 161. These convex teeth 161 and 162 are formed into triangular teeth, sin-shaped teeth, trapezoidal teeth, or the like. That is, the 2nd inner peripheral side convex tooth 161 and the 2nd outer peripheral side convex tooth 162 have the tapering front-end | tip part in the axial direction upper part, and are formed in the comb-tooth shape which continues in the circumferential direction. The surfaces of the second inner peripheral convex teeth 161 and the second outer peripheral convex teeth 162 are coated with, for example, a diamond-like carbon (DLC) film to increase the hardness.

  The second inner peripheral convex teeth 161 are opposed to the first inner peripheral convex teeth 152 and the first outer peripheral convex teeth 153 in the radial direction of the fluid mixed material. Is arranged. The second outer peripheral convex teeth 162 are arranged radially outward of the first outer peripheral convex teeth 153 so as to face the first outer peripheral convex teeth 153 in the flow direction of the fluid mixed material. .

  The tips of the second inner peripheral convex teeth 161 and the second outer peripheral convex teeth 162 have a slight gap with respect to the disk portion 151 of the first annular dispersion member 150. The circumferential edges of the second inner peripheral convex teeth 161 and the second outer peripheral convex teeth 162 are tooth tips of the second inner peripheral convex teeth 161 and the second outer peripheral convex teeth 162 that are adjacent in the circumferential direction, respectively. The gap width on the side is substantially the same as the gap width on the tooth base side. That is, as shown in FIG. 6, the first convex teeth 152 and 153 and the second convex teeth 161 and 162 partially overlap in the radial direction. And when the 1st cyclic | annular dispersion member 150 and the 2nd cyclic | annular dispersion member 160 rotate relatively, the part which the 1st convex teeth 152 and 153 and the 2nd convex teeth 161 and 162 overlap will change.

  The operation of the mixing and dispersing apparatus described above will be described. When the drive motor 40 operates, the partition plate 120, the rotary blade 130, and the first annular dispersion member 150 rotate with respect to the housing 110. On the other hand, since the guide member 140 and the second annular dispersion member 160 are fixed to the housing 110, they do not rotate.

  When the rotating blade 130 rotates, the rotating blade 130 and the guide member 140 act as a diffuser pump, and the fluid base material is sucked into the fluid material side region E1 from the fluid material suction port 111. . The sucked fluid base material passes through the rotary blade 130 and the fluid material guide passage 141 and is delivered to the mixing region. The powder material is sucked into the powder side region E2 from the powder suction port 112 by the flow of the fluid base material. The sucked powder material passes through the powder guide passage 142 and is guided to the mixing region.

  In the mixing region, the first annular dispersion member 150 and the second annular dispersion member 160 are disposed. Then, from the radially inner side toward the radially outer side, the first inner circumferential convex teeth 152, the second inner circumferential convex teeth 161, the first outer circumferential convex teeth 153, and the second outer circumferential convex teeth 162 are arranged in this order. Arranged and rotating relative to each other. Therefore, the fluid base material and the powder material delivered from the guide member 140 are mixed and dispersed by the shearing force of the respective convex teeth 152, 153, 161, 162 while being mixed. Then, the fluid mixed material that has passed through the second outer peripheral convex teeth 162 is discharged from the discharge port 113. In this way, a fluid mixed material is produced. When this operation is continued, the fluid mixed material previously generated from the fluid material suction port 111 is sucked and mixed and dispersed again with the powder material.

  And both the 1st convex teeth 152 and 153 and the 2nd convex teeth 161 and 162 are formed so that a clearance gap may spread from the tooth base side toward the tooth tip side. Therefore, when coating the first convex teeth 152 and 153 and the second convex teeth 161 and 162, it is possible to reliably coat the tooth base sides of both. Even when the metal powder is dispersed, sufficient dispersion capacity and durability can be secured. In addition, although stress is concentrated in the vicinity of the tooth root, if the hardness can be increased by coating, sufficient durability can be ensured even if high stress is applied. Furthermore, even if only one of the first convex teeth 152 and 153 and the second convex teeth 161 and 162 can be increased in hardness, the entire mixing and dispersing device has a low hardness if the other convex teeth are low. The dispersibility and durability are determined by the other convex teeth. However, according to the above embodiment, since both the first convex teeth 152 and 153 and the second convex teeth 161 and 162 can be reliably coated, the dispersibility and durability can be reliably increased. it can. Furthermore, since the circumferential edge surfaces of the first convex teeth 152 and 153 and the second convex teeth 161 and 162 are inclined, the dispersion ability and durability can be easily adjusted by changing the inclination angle.

  Further, when the first convex teeth 152, 153 and the second convex teeth 161, 162 are formed so as to protrude in the axial direction, as shown in FIGS. 6 and 7, the first convex teeth 152, 153 are formed. By adjusting the relative position in the axial direction of the first convex teeth 161 and 162, the first convex teeth 152 and 153 and the second convex teeth 161 and 162 are opposed to each other in the radial direction (diameter overlapping portions: hatching). Area) can be adjusted. Accordingly, the dispersion ability of the first convex teeth 152 and 153 and the second convex teeth 161 and 162 can be easily adjusted.

<Second embodiment>
The mixing and dispersing apparatus of the present embodiment will be described with reference to FIGS. The mixing and dispersing device of this embodiment is configured so that the first annular dispersing member 150 and the second annular dispersing member 160 in the mixing and dispersing device of the first embodiment are on the downstream side of the rotating blades 130 and are axial with respect to the rotating blades 130. It was decided to arrange at different positions in the direction. Further, the guide member 140 is replaced with a stator 270 with a hole and a rotating outer blade 240. Hereinafter, differences will be described. Here, the same configuration or the configuration having the same function is denoted by the same reference numeral and description thereof is omitted.

  The apparatus main body 200 includes a housing 110, a partition plate 120, rotating blades 130, a stator with holes 270, rotating outer blades 240, a first annular dispersion member 150, and a second annular dispersion member 160. The housing 110 has a smaller diameter and a longer axial length than the first embodiment.

  The holed stator 270 is formed in a cylindrical shape having a plurality of through holes 271 in the radial direction, and is fixed to the housing 110. The holed stator 270 is disposed radially outward of the partition plate 120 and the rotary blade 130. That is, the holed stator 270 is disposed radially outward of the fluid material side region E1 and the powder side region E2. The fluid base material in the fluid material side region E1 and the powder material in the powder side region E2 pass through the through holes 271 and move to the mixing region. That is, the holed stator 270 forms boundaries between the flowable material side region E1 and the powder side region E2 and the mixing region.

  The rotating outer blades 240 are disposed radially outward of the stator 270 with holes, and send the fluid mixed material outward in the radial direction. However, the channel on the downstream side of the rotating outer blade 240 is formed to be folded back inward in the radial direction. That is, the rotating outer blades 240 function as a pump that delivers the fluid mixed material downstream.

  The first annular dispersion member 150 and the second annular dispersion member 160 are disposed at different positions in the axial direction from the rotary vane 130, and are located downstream of the flow path folded radially inward from the rotary outer vane 240. And, it is arranged in the flow path which goes radially outward. In particular, the first annular dispersion member 150 and the second annular dispersion member 160 are disposed at the same position in the radial direction as the rotary blade 130 and the rotary outer blade 240. The first annular dispersion member 150 and the second annular dispersion member 160 function in substantially the same manner as in the first embodiment.

  Here, in the present embodiment, the radial positions of the first annular dispersion member 150 and the second annular dispersion member 160 are located radially inward compared to the first embodiment. The first annular dispersion member 150 rotates integrally with the rotary blade 130. At this time, the rotating blade 130 exerts a force to send the fluid material from the radially inner side to the radially outer side as it rotates at a higher speed. The higher the flow rate of the flowable material, the higher the dispersion capacity. On the other hand, the higher the peripheral speed of the first annular dispersion member 150 (the higher the speed), the higher the dispersion capacity. Therefore, when the rotary blade 130 and the first annular dispersion member 150 are rotated at a high speed, the dispersion capability is rapidly increased. On the contrary, when the rotary blade 130 and the first annular dispersion member 150 are rotated at a low speed, the dispersion ability is rapidly lowered. Thus, it is not easy to adjust the dispersion capacity.

  However, the first annular dispersion member 150 is arranged at a different position in the axial direction with respect to the rotary blade 130. Therefore, the radial position of the first annular dispersion member 150 can be freely adjusted. That is, the peripheral speed of the first annular dispersion member 150 can be freely adjusted without reducing the rotational speed of the rotary blade 130. Therefore, it is possible to freely adjust the dispersion capacity while sufficiently securing the flow rate of the fluid material.

<Third embodiment>
The mixing and dispersing apparatus of the present embodiment will be described with reference to FIGS. The mixing and dispersing device of this embodiment is configured so that the protruding directions of the convex teeth 152, 153, 161, and 162 of the first annular dispersing member 150 and the second annular dispersing member 160 in the mixing and dispersing device of the second embodiment are changed from the axial direction to the diameter. Changed to be in the direction. Hereinafter, differences will be described. Here, the same configuration or the configuration having the same function is denoted by the same reference numeral and description thereof is omitted. Here, the mixing and dispersing apparatus of the present embodiment is arranged so that the rotation axis direction is the gravity direction, and is arranged so that the lower side of FIG. 10 is the lower direction of the gravity direction.

  The first annular dispersion member 350 constituting the apparatus main body 300 is disposed below the rotary blade 130. The first annular dispersion member 350 includes a cylindrical portion 351, first upper convex teeth 352, and first lower convex teeth 353. The cylindrical portion 351 is connected to the lower edge of the rotary blade 130. The first upper convex teeth 352 are formed as shown in FIG. That is, a plurality of first upper convex teeth 352 are formed in the circumferential direction so as to protrude outward in the radial direction. Further, the circumferential edge surface of the first upper convex tooth 352 has a gap width from the tooth base side to the tooth tip side of the first upper convex tooth 352 adjacent in the circumferential direction in the full length in the protruding direction (full length in the radial direction). It is formed so as to be wider. The first lower convex teeth 353 are formed in the same shape as the first upper convex teeth 352.

  The second annular dispersion member 360 includes second upper convex teeth 361, second lower convex teeth 362 and a partition plate 363. The second upper convex teeth 361 are formed as shown in FIG. That is, a plurality of second upper convex teeth 361 are formed in the circumferential direction so as to protrude radially inward. Further, the circumferential edge surface of the second upper convex tooth 361 has a gap width from the tooth base side to the tooth tip side of the second upper convex tooth 361 adjacent in the circumferential direction in the full length in the protruding direction (full length in the radial direction). It is formed so as to be wider. The second lower convex teeth 362 are formed in the same shape as the second upper convex teeth 361. The second upper convex teeth 361 are arranged between the first upper convex teeth 352 and the first lower convex teeth 353, and the second lower convex teeth 362 are the first lower convex teeth. 353 is disposed on the lower side.

  The partition plate 363 is formed in a disk shape having a through hole at the center, and the outer peripheral side thereof is fixed to the housing 110. The partition plate 363 is disposed so as to face the upper side of the first upper convex tooth 352. That is, the partition plate 363 is provided in order to return the flow path downstream from the rotating outer blades 240 radially inward from the rotating outer blades 240. Then, the flowable material that has passed through the partition plate 363 reaches the root side of the first upper convex tooth 352, and most of the fluid material flows to the tip side of the first upper convex tooth 352, and then the second upper convex tooth. 361 reaches the tooth base side. And mainly, the tooth tip side of the second upper convex tooth 361 → the tooth base side of the first lower convex tooth 353 → the tooth tip side of the first lower convex tooth 353 → the tooth base side of the second lower convex tooth 362 → Distributes in the order of the tooth tip side of the second lower convex tooth 362 → the discharge port 113.

  The fluid material is dispersed when it flows between the first convex teeth 352 and 353 and the second convex teeth 361 and 362. This is the same as in the second embodiment. In this embodiment, an increase in pipe loss can be suppressed and dispersion efficiency can be increased by reducing the flow path length, reducing the number of turns or reducing the turn angle as compared with the second embodiment. In addition, the fluid material can be circulated without increasing the rotational speed of the rotating blade 130 and the rotating outer blade 240 so much by circulating the fluid material while using gravity.

<Fourth embodiment>
In the mixing and dispersing apparatus of the present embodiment, a plurality of through holes are provided on the tooth tip sides of the first convex teeth 352 and 353 and the second convex teeth 361 and 362 in the mixing and dispersing apparatus of the third embodiment. Others have the same configuration.

  As shown in FIG. 13, the first upper convex tooth 352 in the present embodiment has a plurality of through holes 352a penetrating in the flow direction, that is, in the axial direction, on the tooth tip side. A through hole is not formed on the tooth base side of the first upper convex tooth 352. The first lower convex teeth 353 are the same as the first upper convex teeth 352. Further, as shown in FIG. 14, the second upper convex tooth 361 has a plurality of through holes 361a penetrating in the flow direction, that is, in the axial direction, on the tooth tip side. A through hole is not formed on the tooth base side of the second upper convex tooth 361. The second lower convex teeth 362 are the same as the second upper convex teeth 361.

  In this case, the flowable material that has circulated to the positions of the first convex teeth 352 and 353 is formed between the first convex teeth 352 and 353 adjacent in the circumferential direction and through holes formed in the first convex teeth 352 and 353. Pass through 352a. The gaps between the first convex teeth 352 and 353 adjacent to each other in the circumferential direction are mainly passed through the gap between the tooth tips and the through hole 352a formed on the tooth tip side of the first convex teeth 352 and 353. . The same applies to the second convex teeth 361 and 362. And since the direction which the 1st convex teeth 352 and 353 and the 2nd convex teeth 361 and 362 protrude is an opposite direction, fluid material is the 1st convex teeth 352 and 353 and the 2nd convex teeth 361 and 362. By receiving the shear force reliably. Therefore, the fluid material can be reliably dispersed and homogenized.

<Fifth embodiment>
The mixing and dispersing apparatus of this embodiment will be described with reference to FIG. The mixing / dispersing device of the present embodiment is changed to a shape in which the upper and lower surfaces of the first convex teeth 352, 353 of the first annular dispersion member 350 in the mixing / dispersing device of the third embodiment are inclined. Hereinafter, differences will be described. Since others are the same structures, description is abbreviate | omitted.

  As shown in FIG. 15, the upper and lower surfaces of the first upper convex teeth 352 and the first lower convex teeth 353 are tapered so that the axial thickness decreases from the radially inner side toward the radially outer side. Is formed. Specifically, the upper surface is formed in a tapered shape that inclines below gravity, and the lower surface is formed in a tapered shape that inclines upward in gravity.

  On the other hand, the axial thicknesses of the second convex teeth 361 and 362 and the partition plate 363 are the same. Therefore, the axial clearance between the lower surface of the partition plate 363 and the upper surface of the first upper convex tooth 352, the axial clearance between the lower surface of the second upper convex tooth 361 and the upper surface of the first lower convex tooth 353, and the first upper convex The axial clearance between the lower surface of the tooth 352 and the upper surface of the second upper convex tooth 361 and the axial clearance between the lower surface of the first lower convex tooth 353 and the upper surface of the second lower convex tooth 362 are within the radial direction. The outer radial direction is wider than the one.

  Here, the peripheral speed increases as the diameter increases. Therefore, if the axial clearance is the same regardless of the radial direction, the rate of the shear force that the fluid material receives is greater in the radially outward direction than in the radial direction. However, as in this embodiment, by forming the axial gap so as to increase from the radially inner side to the radially outer side, the shear rate can be made the same even if the radial position is different. . Accordingly, a homogeneous fluid mixed material can be produced.

<Sixth embodiment>
The mixing / dispersing apparatus of the present embodiment will be described with reference to FIGS. The mixing and dispersing apparatus of the present embodiment is a partial modification of the mixing and dispersing apparatus of the second embodiment. Hereinafter, differences will be described.

Convex teeth 161, rotating outer blades 240, and second filtration member 690 are provided.

  The first filtration member 670 (powder filtration member, flowable material filtration member) is formed in a cylindrical shape, and is disposed radially outward of the partition plate 120 and the rotary blade 130. That is, the first filtering member 670 is disposed at the boundary between the fluid material side region E1 and the powder side region E2 and the mixing region. The first filtration member 670 is connected to the rotary blade 130 and rotates integrally with the rotary blade 130. A plurality of through holes 671 penetrating in the radial direction are formed in a portion of the first filtration member 670 that partitions the fluid material side region E1 and the mixing region and a portion that partitions the powder side region E2 and the mixing region. , 672 are formed. That is, the through hole 671 on the powder material side is filtered (dispersed) when the powder material passes through, and the through hole 672 on the fluid material side is filtered (dispersed) when the fluid material passes through. . Here, the size of the through hole 672 on the fluid material side is formed larger than the size of the through hole 671 on the powder material side.

  That is, the powder material flowing from the powder side region E2 to the mixing region has a size that can pass through the through hole 671 of the first filtration member 670. Therefore, it is possible to prevent the lump of the powder material from being generated in the mixing region, and to homogenize the fluid mixed material. Further, the powder material flowing from the flowable material side region E1 to the mixing region has a size that can pass through the through hole 672 of the first filtration member 670. Therefore, even if a lump exists in the flowable material, the lump is dispersed, and the flowable mixed material can be homogenized.

  The powder dispersion member 680 is disposed upstream of the first filtration member 670 in the powder side region E2, and is fixed to the housing 110. The powder dispersion member 680 is formed in an arc shape, and is provided in a part in the circumferential direction (two places separated by 180 ° in FIG. 18). The radial clearance between the powder dispersion member 680 and the first filtration member 670 is set to be approximately the same as the diameter of the through hole 671 on the powder side of the first filtration member 670. Therefore, the powder dispersion member 680 disperses the lump of powder material that could not pass through the through hole 671 on the powder side of the first filtration member 670 with the inner peripheral surface of the first filtration member 670. The dispersed powder material can pass through the through hole 671 on the powder side of the first filtration member 670.

  The convex teeth 153 of the first annular dispersion member 150 are disposed radially outward of the first filtration member 670 and are integrally connected to the partition plate 120 and the rotary blades 130. The convex teeth 153 are formed in the same shape as the convex teeth 153 of the second embodiment. The convex teeth 161 of the second annular dispersion member 160 are disposed between the first filtration member 670 and the convex teeth 153 of the first annular dispersion member 150 and are fixed to the housing 110. The convex teeth 161 are formed in the same shape as the convex teeth 161 of the second embodiment.

  The rotating outer blade 240 is disposed radially outward of the convex teeth 153 of the first annular dispersion member 150 and is fixed to the rotating blade 130. Accordingly, the flowable mixed material is delivered radially outward. The second filtration member 690 is formed in a cylindrical shape, and is fixed to the outer edge in the radial direction of the non-rotating spring 240. That is, the second filtration member 690 rotates integrally with the rotating outer blade 240. The second filtration member 690 is formed with a plurality of through holes 691 that penetrate in the radial direction. That is, the fluid mixed material is filtered (dispersed) by passing through the through-hole 691. Thereby, further homogenization of a fluid mixed material can be achieved.
