Description

  The present invention relates to a technique for pulverizing a fluid containing powder and liquid, and more particularly, to a pulverizing apparatus, a pulverizing system, and a pulverizing fluid manufacturing system.

  With the downsizing and high performance of electronic devices, it is desired to improve the mounting density of electronic devices. In response to this demand, for example, in a surface mount type multilayer ceramic capacitor, it becomes possible to realize a small and large-capacity product at a low cost by making the internal electrode a base metal, making the dielectric layer thin and highly laminated, etc. In addition, a module in which passive elements such as capacitors, coils, and filters are built in the substrate is also realized.

  Electronic devices are generally coated with a slurry in which a powder such as filler is dispersed in a resin binder solution to form a green sheet, or paste printed in the same procedure, dried, debindered, and fired. Or manufactured (for example, see Patent Document 1).

  Here, it is known that the powder in the slurry or paste is likely to aggregate and form a lump. The particle size and shape of the powder in the slurry and paste have a great influence on the characteristics and reliability of the electronic device to be manufactured. For this reason, a pulverization operation for dispersing the aggregated mass and giving a predetermined particle diameter and shape is required.

  FIG. 11 is a schematic configuration diagram of a crusher 500 according to a conventional example. FIG. 12 is a diagram illustrating an operating state of the pulverizing apparatus 500.

  A conventional pulverizing apparatus 500 includes a disk-shaped first mortar body 510 and a second mortar body 520, which are disposed in close contact with each other. A supply hole 511 is formed in the center of the first die 510, and the mixture of liquid and powder introduced from the introduction part 550 passes through the supply hole 511 and the first die 510 and the second die 520. Into the vacant space 530.

A drive source (not shown) is connected to the first mortar 510, and when the drive source is operated, the first mortar 510 performs a rotational motion with the center as a rotation axis. Then, the mixture flowing into the empty space 530 is rubbed and pulverized between the first mortar body 510 and the second mortar body 520. In this way, the powder is pulverized to form a slurry, and this slurry is discharged from the discharge portion 540 to the outside.
Japanese Patent Laid-Open No. 5-116105

  However, in the pulverizing apparatus described above, the mixture flowing into the void is unevenly distributed near the center of the first mortar where the supply hole is located. For this reason, in the vicinity of the center of the first mortar, there is a large amount of powder contained in the mixture, and powder that has been insufficiently pulverized or not pulverized may accumulate without being discharged. The accumulated powder closes the voids or widens the voids to separate the first and second mortars to reduce the grinding efficiency due to friction. In the latter case, particularly in the portion other than the vicinity of the center of the first mortar, the friction of the first mortar and the second mortar is further reduced, and the reduction of the pulverization efficiency is significant.

  In addition, when powder that has been insufficiently pulverized or not pulverized is mixed into the discharged slurry, the characteristics and reliability of an electronic device or the like manufactured using the slurry are reduced.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a pulverization apparatus, a pulverization system, and a pulverization fluid production system capable of sufficiently pulverizing powder contained in a fluid.

  The inventor forms the supply holes through which the mixture passes substantially uniformly over the entire first acetabulum, so that the mixture flows evenly into the cavities of the first acetabulum and the second acetabulum, and is pulverized. The inventors have found that the efficiency can be improved and have completed the present invention. Specifically, the present invention provides the following.

  (1) A pulverizing apparatus for pulverizing a fluid containing powder and liquid, wherein a first mortar having a supply hole through which a fluid passes and a second mortar arranged in close contact with the first mortar A pulverizing apparatus, comprising: a mortar and a driving means for causing the first mortar and the second mortar to rub against each other, wherein the supply holes are positioned substantially evenly over the entire first mortar.

According to the invention of (1), the pulverizer operates as follows.
The fluid introduced into the first mortar passes through the supply hole and flows into a space between the first mortar and the second mortar. When the first die and the second die are rubbed with each other by the driving means, the fluid flowing into the void is crushed.

  Here, since the supply holes are formed substantially uniformly over the entire first mortar, the amount and pressure of the fluid flowing into the voids are also substantially uniform throughout the voids. For this reason, since the fall of the grinding | pulverization efficiency by the uneven distribution of a fluid is suppressed, powder can fully be grind | pulverized.

  (2) The crushing apparatus according to (1), wherein the second mortar has a filter having a predetermined pore diameter.

  According to the invention of (2), since the filter is provided in the second mortar, the powder that has been sufficiently pulverized passes through the filter, while the lump that remains without being sufficiently pulverized passes through the filter. It remains in the void without. The lump remaining in the void is continuously pulverized, and passes through the filter as powder when the pore diameter of the filter is reduced. As described above, the sufficiently pulverized and insufficiently separated materials are separated on the basis of the pore diameter of the filter, so that the insufficiently pulverized material is mixed in the fluid passed through the second mortar. Can be suppressed.

  In addition, as described above, the amount of fluid flowing in is substantially uniform over the entire void space, so that the amount of lump that remains without passing through the filter is also substantially uniform. For this reason, the phenomenon that the pulverization efficiency is reduced by locally separating the first mortar and the second mortar due to the uneven distribution of the lump is suppressed. Therefore, the powder can be sufficiently pulverized as in the invention of (1).

  (3) In the pulverizing apparatus according to (1) or (2), the driving means includes horizontal driving means for moving the first and second acetabular bodies horizontally relative to the opposing surfaces. Crushing equipment.

  In order to make the first and second acetables rub, they may be moved relatively, and examples of the relative motion include a rotational motion and a horizontal motion. However, in rotational motion, the relative motion speed decreases toward the center of rotation, and the relative motion speed increases toward the outer periphery of rotation. For this reason, if the place in a void differs, the friction energy which arises in a 1st mortar and a 2nd mortar, and also a difference in crushing efficiency will arise. Therefore, it is difficult to obtain a homogeneously pulverized fluid.

  Therefore, according to the invention of (3), since the driving means is provided with the horizontal driving means, the first and second acetables move horizontally relative to the opposing surface. The “horizontal motion” referred to here is a motion in which the motion speed of all the moving portions is substantially constant, and specifically, a motion that does not substantially include a rotational motion. Therefore, since the frictional energy generated in the first and second dies, and thus the pulverization efficiency, is almost uniform at any location in the void, a uniformly pulverized fluid can be obtained.

  Here, the horizontal motion with respect to the opposing surface may be a motion in which a component related to another direction is included in the vector of the motion as long as the component related to the horizontal direction of the opposing surface exists.

  (4) The pulverizing apparatus according to (3), wherein the horizontal driving means includes circular motion driving means for relatively circularly moving the first mortar and the second mortar.

  According to the invention of (4), since the circular motion driving means is provided in the horizontal driving means, the first mortar and the second mortar move in a circular motion relative to the opposing surface horizontally. In the process, the first and second acetables move relative to each other at equal distances, so that the phenomenon that the fluid in the void is unevenly distributed over time is suppressed. Therefore, high grinding efficiency can be maintained over a long period of time.

(5) In the grinding apparatus according to any one of (1) to (4),
The pulverizing apparatus is configured so that the supply hole has a shape that expands toward the second acetabulum.

  According to the invention of (5), since the diameter of the supply hole is increased toward the second acetabulum, the powder or fluid that has entered the supply hole flows into the void along the wall surface forming the supply hole. And diffused from the supply hole. Accordingly, since the powder or fluid flows over a wide area of the void, the reduction of the pulverization efficiency due to the uneven distribution of the fluid is further suppressed, and the powder can be pulverized more sufficiently.

  (6) The pulverizing apparatus according to any one of (1) to (5), further comprising a vibration unit that ultrasonically vibrates at least one of the first mortar and the second mortar.

  According to the invention of (6), since the vibration means is further provided, the first and / or second acetabulum vibrates ultrasonically, and this vibration is conducted to the fluid in the void. Thereby, crushing of the lump remaining in the fluid in the void is promoted, so that the powder can be quickly and sufficiently pulverized.

  (7) The pulverizing apparatus according to any one of (1) to (6), further comprising an urging unit that urges the first mortar and the second mortar to approach each other.

The fluid that has flowed into the void acts to separate the first and second dies from each other until they pass through the second dies. For this reason, the 1st mortar and the 2nd mortar may separate, and as a result, crushing efficiency may fall.
Therefore, according to the invention of (7), since the urging means is provided, the first mortar and the second mortar are urged so as to approach each other. Thereby, since the 1st mortar body and the 2nd mortar body are suppressed from separating, the fall of crushing efficiency can be controlled.

  (8) A crushing system comprising a plurality of crushing devices according to any one of (1) to (7), wherein the crushing device is arranged so that the second acetables face each other, A pulverization system further comprising a discharge portion provided in a flow path between the second mortar bodies and communicating with the outside.

  According to the invention of (8), the fluid pulverized by the plurality of pulverizers is guided to the flow path defined by the second mortars through the respective second mortars. Thereafter, the fluid is discharged to the outside from a discharge portion provided in the flow path. Thus, since a flow path is shared by a plurality of pulverizers, the configuration can be simplified.

  (9) A pulverizing fluid production system comprising: a stirring and mixing device that stirs and mixes liquid and powder; and the pulverizing device according to any one of claims 1 to 6, wherein the stirring and mixing device includes a flow path therein. And a stirring body having a vibration shaft arranged inside the casing and connected to a vibration source and a stirring blade provided around the vibration shaft, and the fluid discharged from the casing is A pulverized fluid production system for supplying the first mortar to the opposite side of the second mortar.

  According to the invention of (9), a strong vortex flow is generated inside the casing as the stirring blades vibrate, so that the liquid and the powder are highly stirred and mixed. For this reason, the fluid discharged from the casing and supplied to the first mortar is highly agitated in advance to reduce the lump. Therefore, the powder can be pulverized more quickly and sufficiently.

  According to the present invention, since the supply holes are formed substantially evenly over the entire first acetabulum, the amount and pressure of the fluid flowing into the voids are also substantially uniform throughout the voids. For this reason, since the fall of the grinding | pulverization efficiency by the uneven distribution of a fluid is suppressed, powder can fully be grind | pulverized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in description of each embodiment other than 1st Embodiment, the same code | symbol is attached | subjected about what is common in 1st Embodiment, and the description is abbreviate | omitted.

<First Embodiment>
FIG. 1 is an overall perspective view of a pulverizing apparatus 20 according to the first embodiment of the present invention. FIG. 2 is a perspective side view of FIG.

[Crusher]
The pulverizing apparatus 20 for pulverizing a fluid includes a housing 21 in which a first mortar body 30 and a second mortar body 40 are stored. The first mortar body 30 and the second mortar body 40 are arranged in close contact with each other with a small space 55 therebetween. In addition, at least one of the first mortar body 30 and the second mortar body 40, in the present embodiment, the first mortar body 30 is connected to a driving unit 80 as driving means, and the second umbilical body 40 is driven by the driving unit 80. And rubbed.

[Body]
The casing 21 includes a cylindrical casing main body 23 having a bottom portion, and a donut-shaped expansion / contraction section 27 having a predetermined width is provided at an upper end of the casing main body 23 so as to be inscribed therein. The inner peripheral surface of the expansion / contraction part 27 is connected to a crown part 25 described later.

  The crown portion 25 is provided with an introduction path 67 to be described later, and the mixture as a fluid introduced from the introduction path 67 into the introduction region 53 passes through the first mortar body 30 and the second mortar body 40, and the slurry. Is derived to the derivation region 57. A discharge part 75 provided below the second mortar body 40 is provided on the side surface of the casing main body 23, and the slurry guided to the lead-out area 57 is discharged from the discharge part 75 to the outside.

[First acetabulum]
The first mortar body 30 includes a disk-shaped first mortar body 31, and one surface of the first mortar body 31 is covered with a reverse funnel-shaped crown portion 25 facing its wide mouth. Yes. An introduction path 67 is connected to the narrow opening of the crown portion 25, and a mixture of powder and liquid is introduced into the introduction area 53 from the introduction path 67. A connecting portion 87, which will be described later, is fixed to the outer surface of the crown portion 25, and is indirectly connected to the rotary motor 81 that is a drive source via the connecting portion 87. Thus, as will be described in detail later, when the rotary motor 81 is driven, the first mortar body 30 moves.

  The introduction region 53 refers to an internal space defined by the crown portion 25 and the first mortar body 31. As a mixture, the filler for electronic devices is mentioned, for example.

  A plurality of supply holes 33 are formed in the first mortar body 31. Since the introduction region 53 and the void 55 are communicated with each other through the supply holes 33, the mixture introduced into the introduction region 53 flows into the void 55. Here, since the supply holes 33 are formed at substantially equal intervals over the entire first mortar body 31, the mixture also flows in substantially evenly over the entire space 55.

  The supply hole 33 has a shape that increases in diameter toward the second mortar body 40 side. As a result, the mixture that has entered the supply hole 33 flows into the void 55 along the wall surface 34 that forms the supply hole 33, diffuses and is discharged from the supply hole 33. In the present embodiment, a part of the supply hole 33 has a tapered shape, but is not particularly limited thereto.

  The diameter and number of the supply holes 33 may be appropriately set according to the amount and characteristics of the fluid to be pulverized, the permeability of the second mortar 40, and the like. In the present embodiment, all the supply holes 33 have substantially the same shape and hole diameter, but the present invention is not particularly limited thereto.

  The first mortar body 30 driven by the drive unit 80 is horizontal to the opposing surfaces of the first mortar body 30 and the second mortar body 40, in other words, the surfaces of the first mortar body 30 and the second mortar body 40. Move along the faces of each other. That is, the drive unit 80 in this embodiment constitutes a horizontal drive unit. Since the first mortar body 31 is disposed between the housing body 23 and the movement region 54 for the first mortar body 30 to move horizontally, the first mortar body 31 is moved during the horizontal movement. There is no contact with the housing body 23.

[Second acetabulum]
The second mortar body 40 includes a disk-shaped filter 41 having a predetermined hole diameter, and the filter 41 is fixed to the inner wall of the housing main body 23 via a frame body 42 that surrounds the outer periphery. For this reason, all of the slurry led out to the lead-out region 57 penetrates the filter 41, so that the amount of massive powder in the slurry is reduced. A part of the frame body 42 protrudes outward to form a conductive portion 91. The conductive portion 91 extends through the housing body 23 to an installation position of an ultrasonic transducer 92 described later.

  The width of the filter 41 is preferably wider than the entire range facing the first mortar body 31 during the later-described movement. The pore size of the filter 41 is set larger than the desired particle size of the powder contained in the slurry. However, it is preferable that the pore diameter of the filter 41 is set in consideration of the fact that a large amount of agglomerated powder permeates if it is too large.

  If the thickness of the filter 41 is too small, the filter 41 is pushed down by the mixture in the void 55 due to insufficient strength, and a gap with the first mortar body 30 is opened. Thereby, the grinding efficiency is reduced. On the other hand, when the thickness of the filter 41 is too large, the time required for the slurry to pass through the filter 41 becomes excessively long, and the production efficiency of the slurry decreases.

[Stirring and mixing device]
FIG. 3 is a schematic configuration diagram of the stirring and mixing device 60. As shown in FIG. 3, the stirring and mixing device 60 includes a device casing 61 having a flow path therein, and a stirring body 63 is disposed inside the device casing 61. The vibration shaft 631 of the stirring body 63 is connected to the vibration source 62, and a spiral blade 632 serving as a stirring blade is provided around the vibration shaft 631. Thereby, the stirring body 63 moves up and down in the apparatus casing 61, and powder and fluid can be stirred and mixed.

  In addition, a partition plate 65 is provided in the device casing 61, and the partition plate 65 partitions the internal space of the device casing 61 to form a plurality of stirring chambers 64a to 64d. An opening is formed in the center of the partition plate 65, and the vibration shaft 631 is inserted through this opening.

  When the vibration source 62 is driven, the spiral blade 632 vibrates up and down via the vibration shaft 631. As a result, a strong vortex flow is generated in the stirring chambers 64a to 64d in the raw material introduced into the apparatus casing 61. The raw material is mixed by this vortex.

  On the other hand, a filtration filter 66 is provided on the upper end side of the apparatus casing 61. The stirred mixture that has moved to the stirring chamber 64d through the flow path inside the apparatus casing 61 is filtered by the filtration filter 66, and undissolved or unmelted material is removed. An introduction path 67 is provided downstream of the filtration filter 66, and the mixture filtered by the filtration filter 66 flows into the introduction path 67 and is introduced into the introduction region 53 before long. A pump 671 is provided in the middle of the introduction path 67, and this pump 671 pumps the mixture to the introduction region 53, so that backflow of the mixture from the introduction region 53 can be prevented.

  Such a stirring and mixing device 60 constitutes a pulverized fluid production system according to the present invention in combination with the pulverizing device 20.

[Energizing part]
The crushing device 20 further includes an urging unit 70 as an urging unit that couples the bottom of the housing body 23 and the second mortar body 40. The urging unit 70 is urged so that the first mortar body 30 and the second mortar body 40 approach each other in order to push the second mortar body 40 toward the first mortar body 30.

  In the present embodiment, the urging unit 70 is configured to be extendable and contractible with a spring member, but is not limited thereto, and may be a fixed object that is not expandable and contractible. Moreover, it is preferable that the urging | biasing part 70 is provided in the position where the 2nd die 40 is easy to be pushed down with a mixture according to the range, direction, etc. which the 1st die 30 moves. In this regard, when the first mortar body 30 and the second mortar body 40 are relatively circularly moved, friction is generated substantially evenly at all points of the void 55, so that the urging portion 70 has the housing body 23. What is necessary is just to arrange | position substantially uniformly over the whole bottom surface part and the 2nd die 40.

[Drive part]
The drive unit 80 relatively moves the first mortar body 30 and the second mortar body 40. In the present embodiment, the drive unit 80 includes a rotation motor 81, and the rotation shaft 83 connected to the rotation motor 81 rotates in the axial direction by the driving force. An eccentric cam 84 is fixed around the rotary shaft 83.

  On the other hand, the connecting portion 87 provided in the crown portion 25 extends horizontally with respect to the opposing surfaces of the first mortar body 31 and the filter 41, and includes a donut-shaped support frame 88 in the vicinity of the tip thereof. The support frame 88 protrudes perpendicularly to the direction in which the connecting portion 87 extends, and the connecting portion 87 supports the eccentric cam 84 via a bearing 85 provided on the inner wall of the support frame 88. Accordingly, when the rotary motor 81 is operated, the support frame 88 and the connecting portion 87 perform a circular motion, and the first mortar body 31 moves circularly with respect to the opposing surface via the crown portion 25 connected to the connecting portion 87. Will do. Thus, the drive part 80 comprises a horizontal drive means and a circular motion drive means. In the present embodiment, the connecting portion 87 is connected to the crown portion 25. However, the connecting portion 87 may be directly connected to the first mortar body 31.

  However, the driving principle is not particularly limited, and for example, a system in which the first mortar body 30 is moved by a change in the magnetic field may be used. In this case, since the magnetic field from the drive unit arranged outside the housing 21 passes through the housing 21, the first body 30 can be moved without connecting the first body 30 through the housing 21. Can exercise. Thereby, since the airtightness inside the housing 21 improves, mixing of the impurity to a slurry can be suppressed.

  In addition, the motion speed of the first mortar 30 changes the composition of the mixture, the desired particle diameter of the powder contained in the slurry, and the materials of the first mortar 30 and the second mortar 40 (the generated friction energy varies). ) And the like. If the movement speed of the first mortar body 30 is too small, the pulverization is insufficient. On the other hand, if the movement speed is too large, the powder may be damaged or burnt by frictional heat of the first mortar body 30 and the second mortar body 40. There is.

[Vibration part]
The crushing device 20 further includes a vibration unit 90 as a vibration unit, and the vibration unit 90 includes an ultrasonic vibrator 92 provided in the conduction unit 91. An oscillator 93 is electrically connected to the ultrasonic vibrator 92, and a high-frequency current is supplied from the oscillator 93 to the ultrasonic vibrator 92, so that the ultrasonic vibrator 92 generates ultrasonic vibration. . Then, the ultrasonic vibration generated by the ultrasonic vibrator 92 is conducted to 40 through the conductive portion 91, and the mixture in the void 55 is vibrated vigorously.

  In this embodiment, the vibration unit 90 vibrates the second mortar body 40, but may vibrate the first mortar body 30 and vibrate both the first mortar body 30 and the second mortar body 40. May be.

[Operation]
The operation of the pulverizing apparatus 20 will be described. First, a mixture of liquid and powder is introduced from the stirring and mixing device 60 into the introduction region 53. Then, the mixture introduced into the introduction region 53 passes through the supply hole 33 and flows into the void 55. The mixture flowing into the void 55 attempts to push down the second mortar 40. However, since the second mortar body 40 is urged toward the first mortar body 30 by the urging unit 70, the first mortar body 30 and the second mortar body 40 are prevented from separating.

  Subsequently, when the rotary motor 81 is operated, the rotary shaft 83 rotates the eccentric cam 84. The rotational motion of the eccentric cam 84 causes the rotational energy to be canceled by the bearing 85 and causes the support frame 88 to move circularly. Then, the first mortar body 30 connected to the support frame 88 via the connecting portion 87 rotates. In addition, with the circular motion of the first mortar body 30, the stretchable portion 27 contracts at a portion approaching the crown portion 25 and expands at a portion separated from the crown portion 25. As a result, the first mortar body 30 can circularly move while the sealing of the void 55 is maintained.

  Here, the detail of the movement aspect of the 1st mortar body 30 is demonstrated with reference to FIG. 4A to 4E are diagrams sequentially illustrating the operating state of the crushing device 20 when viewed from above in FIG.

  As shown in FIG. 4A, at the initial stage, the first mortar body 30 and the second mortar body 40 are arranged coaxially. Subsequently, when the drive unit 80 is operated, the first mortar body 30 connected to the drive unit 80 starts a circular motion with respect to the second mortar body 40. After sequentially moving as shown in FIGS. 4B to 4D, it returns to the same position as the initial position as shown in FIG. By repeating the above operation, the first die 30 and the second die 40 rub against each other, and the mixture in the void 55 is crushed.

  During this time, when the oscillator 93 is operated, the ultrasonic vibrator 92 vibrates ultrasonically, and this vibration is conducted to the second mortar body 40 via the conductive portion 91. Then, the mixture in contact with the second die 40 in the void 55 is vigorously vibrated, and the powder contained in the mixture is crushed.

  The mixture thus pulverized becomes a slurry and permeates the filter 41. Eventually, the slurry that has passed through the filter 41 is led out to the lead-out region 57 and then discharged from the discharge part 75 to the outside.

[Function and effect]
According to this embodiment, the following effects can be obtained.

  Since the supply holes 33 are formed substantially uniformly over the entire first die 30, the amount and pressure of the mixture flowing into the void 55 are also substantially uniform throughout the void 55. For this reason, since the fall of the grinding | pulverization efficiency by the uneven distribution of a mixture is suppressed, powder can fully be grind | pulverized.

The powder that has been sufficiently pulverized passes through the second mortar 40, while the lump that remains without being sufficiently pulverized remains in the void 55 without passing through the second mortar 40. The lump remaining in the void 55 is continuously pulverized, and passes through the filter as a powder when the pore diameter of the filter 41 constituting the second mortar body 40 is reduced. As described above, since the sufficiently pulverized and insufficiently separated materials are separated on the basis of the pore diameter of the filter 41, the insufficiently pulverized material is mixed in the slurry passed through the second mortar body 40. Can be suppressed.
Moreover, since the amount of the mixture flowing in is substantially uniform over the entire space 55, the amount of the lump that remains without passing through the filter 41 is also substantially uniform. For this reason, the phenomenon that the first mortar body 30 and the second mortar body 40 are locally separated and the pulverization efficiency decreases due to the uneven distribution of the lump is suppressed. Therefore, the powder can be sufficiently pulverized.

  Since the first mortar body 30 and the second mortar body 40 move horizontally relative to the opposing surfaces, the friction energy generated in the first mortar body 30 and the second mortar body 40 at any location in the void 55, As a result, the grinding efficiency is substantially uniform. Thus, a homogeneously pulverized slurry can be obtained.

  Since the 1st mortar body 30 and the 2nd mortar body 40 carry out circular motion relatively horizontally with respect to the opposing surface, in the process, the 1st mortar body 30 and the 2nd mortar body 40 are equidistant in all directions. Move relative to each other. Thereby, since the phenomenon that the mixture in the void 55 is unevenly distributed with time is suppressed, high grinding efficiency can be maintained over a long period of time.

  Since the diameter of the supply hole 33 is increased toward the second die 40, the mixture that has entered the supply hole 33 flows into the void 55 along the wall surface 34 that forms the supply hole 33, and from the supply hole 33. Diffused and released. Therefore, since the mixture flows over a wide area of the void 55, the reduction in the pulverization efficiency due to the uneven distribution of the mixture is further suppressed, and the mixture can be pulverized more sufficiently.

  Since the vibration unit 90 is further provided, the second mortar body 40 vibrates ultrasonically, and this vibration is conducted to the mixture in the void 55. Thereby, crushing of the lump remaining in the mixture in the void 55 is promoted, so that the powder can be quickly and sufficiently pulverized.

  Since the urging portion 70 is further provided, the first mortar body 30 and the second mortar body 40 are urged so as to approach each other. Thereby, since it is suppressed that the 1st mortar body 30 and the 2nd mortar body 40 space apart, the fall of grinding | pulverization efficiency can be suppressed.

  As the spiral blade 632 vibrates, a strong vortex is generated inside the device casing 61, so that the liquid and the powder are highly stirred and mixed. For this reason, the mixture discharged from the device casing 61 and supplied to the first mortar body 30 is highly agitated in advance to reduce the lump. Therefore, the powder can be pulverized more quickly and sufficiently.

<Second Embodiment>
FIG. 5 is an overall perspective view of a crusher 20A according to the second embodiment of the present invention. 6 is a perspective front view of FIG. This embodiment is different from the first embodiment in that the second mortar body 40 moves.

  That is, a connecting portion 87A is further provided at the tip of the conductive portion 91, and this connecting portion 87A supports the eccentric cam 84A via a bearing 85A provided on the inner wall of the support frame 88A. The eccentric cam 84A is fixed so as to surround the rotation shaft 83A, and the rotation shaft 83A is connected to the rotation motor 81. Thus, when the rotary motor 81A is operated, the second mortar body 40 rotates through the connecting portion 87A and the conductive portion 91.

  Here, around the frame body 42, an extendable portion 27A is provided so as to be inscribed. However, the frame body 42 and the conductive portion 91 are connected through the telescopic portion 27A. Thereby, when the conduction part 91 rotates and ultrasonically vibrates, the energy is directly conducted to the frame body 42, and as a result, the filter 41 vibrates and ultrasonically vibrates.

The casing 21B of the pulverizers 20a and 20b includes a cylindrical casing main body 23B having no bottom, and extendable portions 27a and 27b are provided at both ends of the casing main body 23B, respectively.

  Each of the inner peripheral surfaces of the extendable portions 27a and 27b is connected to the crown portions 25a and 25b. The narrow ports of the crown portions 25a and 25b are communicated with the stirring and mixing device 60, and the mixture is introduced from the stirring and mixing device 60 into the introduction regions 53a and 53b.

  The second mortar bodies 40a and 40b are connected to each other by the urging portion 70, and are urged toward the first mortar bodies 30a and 30b by the urging portion 70, respectively.

  The drive units 80a and 80b cause the second mortar bodies 40a and 40b to move with respect to the first mortar bodies 30a and 30b. Here, the movement conditions (movement range, movement speed, movement path) of the second mortar bodies 40a and 40b may be the same or different. However, it is preferable that the movement conditions of the second mortar bodies 40a and 40b are the same in that the slurries led out from the voids 55a and 55b to the lead-out region 57 can be made uniform.

  In addition, the vibration units 90a and 90b also ultrasonically vibrate each of the second mortar bodies 40a and 40b. Here, the vibrations of the second mortar bodies 40a and 40b may or may not be synchronized. However, it is preferable that the movement conditions of the second mortar bodies 40a and 40b are the same in that the slurries led out from the voids 55a and 55b to the lead-out region 57 can be made uniform. From the same viewpoint, the introduction conditions (introduction speed, introduction pressure) from the stirring and mixing apparatus 60 may be the same or different, but are preferably the same.

  The discharge part 75 is provided in the side surface of the housing main body 23B between the empty spaces 55a and 55b. As a result, the slurry led out from the cavities 55a and 55b to the lead-out region 57 joins in the lead-out region 57 and is then discharged from the discharge unit 75 to the outside. The lead-out area 57 in the present embodiment constitutes a flow path.

[Function and effect]
According to this embodiment, in addition to the operational effects of the second embodiment described above, the following operational effects are obtained.
The slurry pulverized by the plurality of pulverizers 20a and 20b is guided to the lead-out region 57 defined by the second dies 40a and 40b through the second dies 40a and 40b. Thereafter, the slurry is discharged from a discharge portion 75 provided in the lead-out region 57 to the outside. Thus, since the derivation | leading-out area | region 57 is shared by several grinding | pulverization apparatus 20a, 20b, a structure can be simplified.
