Description

  The present invention relates to a dispersion processing system and a dispersion processing method for dispersing substances in a slurry mixture.

  Conventionally, when nano-dispersion is attempted with a bead mill, jet mill, or high-pressure homogenizer (nozzle type disperser), raw materials containing relatively large aggregated particles of several tens to several hundreds of micrometers are processed under the conditions for nano-dispersion. When trying to do so, there is a problem that the agglomerated particles cannot be dispersed or clogging occurs, resulting in poor processing efficiency.

  Therefore, pre-dispersion is performed before nano-dispersion to reduce the particle size of the powder, that is, solid particles to several tens of μm or less. However, when dispersed with a stirring type disperser, the dispersion force itself is weak. In addition, dispersion unevenness is likely to occur. Further, when dispersed with a conventional disk type disperser, the gap is several hundred μm, and it is difficult to make the particles finer than the gap. Therefore, in these conventional dispersers, the efficiency of the entire system has not been improved sufficiently.

  Therefore, an object of the present invention is to provide a distributed processing system and a distributed processing method for performing nano-dispersion processing by efficiently performing preliminary dispersion.

And a second dispersion device 60.

  With this configuration, relatively large agglomerated particles contained in the mixture raw material are dispersed into small particles without unevenness of dispersion by the shearing-type first dispersing device, and the solid particles are efficiently made into nano-level sizes by the second dispersing device. It becomes a distributed processing system to be miniaturized. Note that “dispersion” means that the powdery substance in the slurry is made fine and uniformly present.

Further, the mixture guided between the stator and the rotor from a position outside the rotation shaft insertion hole is guided to the outside by centrifugal force, so that the mixture does not reach the rotation insertion hole, and it is not necessary to provide a sealing device.

  The dispersion processing system for dispersing the slurry-like mixture according to the twelfth aspect of the present invention is the same as that of the eleventh dispersion processing system, for example, as shown in FIGS.

  Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. First, the distributed processing system 100 will be described with reference to FIG. The dispersion processing system 100 mixes a liquid raw material L and a powder raw material P to form a slurry-like mixture 4 (also referred to as “coarse dispersion”), and a mixture 4 supplied from the coarse dispersion device 110. The first dispersion device 1 that pre-disperses in a shearing manner and the mixture 4 that has been pre-dispersed in the first dispersion device 1 are refined into nano-sized solid particles (“nano dispersion” or “finishing”). And a storage tank 120 for storing the mixture 4 dispersed by the second dispersion device 60.

  The nano-sized solid particles mean particles having an average particle size of less than 1 μm. The lower limit for the nano-level size is not particularly defined, but is typically 1 nm. The average particle size can be obtained by measuring the particle size distribution with a laser diffraction particle size distribution analyzer (for example, SALD-2100 manufactured by Shimadzu Corporation) and calculating the median diameter.

  The dispersion processing system 100 further includes a pipe 130 for sending the mixture 4 from the coarse dispersion apparatus 110 to the first dispersion apparatus 1, a pipe 140 for sending the mixture 4 predispersed from the first dispersion apparatus 1 to the second dispersion apparatus 60, and And a pipe 150 for sending the nano-dispersed mixture 4 from the second dispersion device 60 to the storage tank 120. A pump 132 is installed in the pipe 130 and a pump 142 is installed in the pipe 140. In addition, when the 2nd dispersion | distribution apparatus 60 is an air release type, a pump is also installed in the piping 150. Note that the mixture 4 may be sent from the coarse dispersion device 110 to the first dispersion device 1 by gravity without providing the pump 132.

  The coarse dispersion apparatus 110 includes a liquid supply unit 111 that supplies the liquid L and a powder supply unit 112 that supplies the powder P. The liquid supply unit 111 and the powder supply unit 112 may have a known structure. The coarse dispersion device 110 has a rotating shaft 117, a stirring blade 113, and a driving device 118 such as a motor that rotates the stirring blade 113 around the rotating shaft 117 in order to promote mixing of the supplied liquid L and powder P. Have The stirring blade 113 is formed so that the gap between the stirring blade 113 and the wall surface is about 0 to 20 mm. As the stirring blade 113, a metal or a metal attached with a resin is used. By attaching the resin to the metal, metal contamination is prevented. Here, the stirring blade 113 is shaped so as to be scraped off at two locations on the circumference, but the number of stirring blades may be increased to three or more by combining a plurality of plate members. It may be individual. In addition, what promotes mixing is not restricted to the method of rotating the stirring blade 113, and may be another known method.

  The stirring blade 113 is shown as an anchor type in FIG. However, the stirring blade is not limited to the anchor type, and may be a turbine blade 114 such as a disk turbine type impeller as shown in FIG. The stirring blade 114 generates an inclined vortex in the mixture 4 (initially the raw material for treatment) in the coarse dispersion device 110. Furthermore, a disperser type (dissolver type impeller) stirring blade 115 shown in FIG. 2B or a propeller type stirring blade 116 shown in FIG. 2C may be used. Since the stirring blades 113, 114, 115, and 116 are used for stirring, the configuration of the coarse dispersion device 110 is simplified.

  Here, as the powder P, carbon black, carbon nanotubes, graphene, alumina / silica or other inorganic powder, metal or metal oxide powder, or the like is used. A plurality of types of powder raw materials may be used. As the liquid L, water, a solvent such as ethanol, a resin, or the like is used. A plurality of types of liquid raw materials may be used. As the solvent, an organic solvent other than ethanol may be used. As the resin, for example, a thermosetting resin is used. For example, a combination of water and ethanol, ethanol and other solvent and resin, or solvent and resin may be used. There is no particular limitation on the combination of the powder P and the liquid L. By dispersing nano-sized powder P in these liquids L, for example, materials with high rigidity and heat resistance, films with excellent insulation, electrical / electronic parts with excellent electrical properties, chemical properties (for example, Products having characteristics that have not been obtained so far, such as chemical products with excellent reactivity, paints with excellent anticorrosion properties, and lenses with a high refractive index, can be obtained.

  The first dispersing device 1 supplies the slurry-like mixture 4 between the rotor 2 and the stator 3 and disperses them in a shearing manner by the rotor 2 and the stator 3, details of which will be described later.

  The second dispersion device 60 may be a known dispersion device such as a bead mill, a jet mill, or a high-pressure homogenizer. The mixture 4 is preliminarily dispersed by the first dispersing device 1, whereby the aggregated particles are decomposed, and the mixture 4 contains only small particles of several tens of μm or less as will be described later. Therefore, dispersion | distribution nonuniformity does not arise and efficient nano dispersion | distribution is performed. When dispersion unevenness occurs, in the case of a bead mill, it becomes a cause of dispersibility due to mixing of larger aggregated particles than beads. In the case of a jet mill or a high-pressure homogenizer, clogging occurs due to mixing of agglomerated particles that are larger than the nozzle, resulting in poor dispersion and equipment trouble.

  The storage tank 120 includes a rotating shaft 127, a stirring blade 123, and a driving device 128 such as a motor that rotates the stirring blade 123 around the rotating shaft 127 in order to eliminate concentration unevenness of the nano-dispersed mixture 4. The stirring is not limited to the method of rotating the stirring blade 123, and other known methods may be used. The mixture 4 dispersed in the coarse dispersion device 110, the first dispersion device 1 and the second dispersion device 60 that are continuously processed does not always have the same concentration and particle distribution at every moment. It is preferable to stir the mixture 4 stored in step 1 to obtain a uniform mixture 4. Further, by storing the mixture 4 in the storage tank 120, it is possible to prevent the solid particles from being settled and the concentration becoming non-uniform. However, the storage tank 120 does not need to have a stirring means when it is ensured that the concentration and particle size distribution are not uneven. The storage tank 120 may be provided with a vacuum pump (not shown), and the pipes 140 and 150 may be provided with on-off valves (not shown). Defoaming of the mixture 4 after nano-processing becomes possible with a vacuum pump and an on-off valve. If a contact seal such as a lip seal is provided in the first dispersing device 1 in place of the on-off valve to prevent outside air from being mixed in, defoaming can be performed while carrying out a dispersion process.

  Here, the shearing-type first dispersion device 1 will be described with reference to FIGS. The first dispersion device 1 includes a rotor 2 and a stator 3 disposed opposite to the rotor 2, and a slurry-like or liquid mixture 4 is placed between the rotor 2 and the stator 3 on the outer periphery by centrifugal force. Preliminarily disperse by letting it pass (pass in the direction towards the outer circumference).

  The first dispersion apparatus 1 includes a container 11 that receives the mixture 4 after dispersion, and a cover unit 12 that closes the upper opening 11 a of the container 11. For example, the cover unit 12 is fixed to the container 11 by attaching bolts 11d to bolt holes 11c, 18c formed in the upper edge portion 11b of the container 11 and the cover unit 12 (stator holding portion 18 described later). The upper opening 11a is closed.

  The stator 3 is fixed to the lower side (lower surface) of the cover unit 12. For example, the stator 3 is fixed by attaching the bolt 3a to the bolt holes 3b, 18b formed in the stator 3 and the cover unit 12 (stator holding portion 18). The rotor 2 is provided to face the lower surface of the stator 3.

  Moreover, the 1st dispersion device 1 is provided with the rotating shaft 13 which rotates the rotor 2, and the bearing 14 which hold | maintains the rotating shaft 13 rotatably. The bearing 14 is provided and fixed to the cover unit 12 and is positioned above the stator 3.

  The rotor 2 is attached to one end of the rotating shaft 13. A rotating shaft 16a of a motor 16 provided above the stator 3 is attached to the other end via a joint portion 16b. The rotating shaft 13 is rotated by the motor 16 and transmits the rotational force of the motor 16 to the rotor 2.

  Moreover, the 1st dispersion | distribution apparatus 1 is provided with the spacer member 15 provided so that attachment or detachment is possible between the rotating shaft 13 and the rotor 2 (FIG.4 (c), FIG.4 (e) etc.). The spacer member 15 is replaced with a component having a different length (thickness) in the axial direction D1 (see FIG. 3 (a)) of the first dispersing device 1, that is, the rotating shaft 13, whereby the rotor 2 and the stator 3 are replaced. Adjust the gap between them. That is, a plurality of spacer members 15 having different thicknesses are prepared, and the gap between the rotor 2 and the stator 3 is adjusted by attaching the spacer member 15 selected from these.

  The rotor 2 has a fixed position in the axial direction D1 with respect to the stator 3 in a state where the spacer member 15 is attached. That is, for example, a spring, a screw, or the like may be used as a means for adjusting the gap between the rotor 2 and the stator 3. However, when the spacer member 15 described here is used, the axial direction of the rotor 2 is used at the time of use. Since the position is fixed, there is no need to consider spring vibrations, screw gaps, and the like. Moreover, when a spring and a screw are used, precise parallel movement is difficult. On the other hand, when the spacer member 15 is used, fine adjustment is possible.

  The first dispersing device 1 realizes highly accurate gap adjustment with the above-described configuration. Moreover, since the rotor 2 is moved in the direction away from the stator 3 even when the rotating shaft 13 is thermally expanded due to unscheduled heat generation, the first dispersing device 1 can prevent contact between the rotor 2 and the stator 3. Further, excessive heat generation due to unexpectedly small gaps can be prevented even if they do not contact. Further, since the bearing 14 is on the upper side of the stator 3, the rotary shaft 13 is disposed on the upper side of the rotor 2, and the rotary shaft 13 does not exist on the lower side of the rotor 2 (the rotary shaft 13 is directed upward from the rotor 2. Therefore, it is possible to prevent the mixture 4 after the dispersion treatment from adhering to the rotating shaft 13, the bearing 14 and the like and reducing the yield. That is, the yield can be improved.

  The cover unit 12 includes a bearing holding portion 17 that holds the bearing 14, and a stator holding portion 18 that is provided below the bearing holding portion 17 and holds the stator 3. The bearing holding part 17 has a positioning restricting part 21 that restricts the axial position of the stator holding part 18 by contacting the stator holding part 18 via the second spacer member 20. For example, the bearing holding portion 17 is configured such that the bolt 17a is attached to the bolt holes 17e and 18e formed in the bearing holding portion 17 and the stator holding portion 18, so that the stator holding portion is sandwiched between the second spacer members 20. 18 (FIG. 4D, etc.). The second spacer member 20 is provided with an insertion hole 20a through which the bolt 17a is inserted.

  The second spacer member 20 is detachably provided between the bearing holding portion 17 and the stator holding portion 18, and is replaced with a component having a different length (thickness) in the axial direction D <b> 1. The position of the stator 3 in the axial direction D1 is adjusted. That is, a plurality of second spacer members 20 having different thicknesses are prepared, and the position of the stator 3 in the axial direction D1 can be adjusted by attaching the second spacer member 20 selected from these.

  By exchanging the spacer member (also referred to as “first spacer member”) 15 and the second spacer member 20 with respective replacement parts, finer adjustment of the gap between the rotor 2 and the stator 3 is realized. . That is, changing the spacer member 15 to have a large thickness acts in the direction of increasing the gap between the rotor 2 and the stator 3. Changing the second spacer member 20 to have a large thickness acts in the direction of reducing the gap between the rotor 2 and the stator 3. By combining these, finer adjustment is realized. The spacer member 15 and the second spacer member 20 are each about 0.01 mm to 0.50 mm, for example, and a plurality of different thicknesses of 0.01 mm are prepared. The gap between the rotor 2 and the stator 3 is adjusted by exchanging them and attaching them.

  The second spacer member 20 can adjust the position of the stator 3 with respect to the bearing holding portion 17, that is, the position of the lower surface of the stator 3 by adjusting the position of the stator holding portion 18 with respect to the bearing holding portion 17. . Thereby, the position of the lower surface of the stator 3 can be kept constant regardless of the state of the stator 3. For example, even when the stator 3 is replaced, the position of the lower surface of the stator 3 can be kept constant. Accordingly, for example, by holding the position of the lower surface of the stator 3 at a predetermined position, the thickness of the spacer member 15 can be matched with the gap between the rotor 2 and the stator 3, and the configuration can be easily understood by the user. That is, in order to obtain a desired gap, the spacer member 15 having the same thickness may be selected. The convenience of the user who manages the gap and performs distributed processing can be improved.

  A recess 22 for inserting the lower end 13a of the rotating shaft 13 is provided on the upper surface of the rotor 2 (FIG. 4C, FIG. 4E, etc.). The rotor 2 is formed with a through hole 22 a that opens to the recess 22. The fastening member 23 is attached from the lower surface side of the rotor 2 in a state where the lower end 13a of the rotary shaft 13 is inserted into the concave portion 22 of the rotor 2 and the lower end 13a is in contact with the concave portion 22 via the spacer member 15. The fastening member 23 is, for example, a mounting bolt, and a female screw portion is formed on the lower end 13 a of the rotating shaft 13 as a fastening portion 13 b corresponding to the fastening member 23.

  A part of the fastening member 23 passes through the through hole 22 a of the rotor 2 and is attached to the rotary shaft 13, thereby fastening the rotary shaft 13 and the rotor 2 with the spacer member 15 interposed therebetween. A plurality of pins 24 for transmitting the rotational force of the rotating shaft 13 to the rotor 2 are inserted into the recess 22 of the rotor 2 and the lower end 13 a of the rotating shaft 13. A hole for inserting the pin 24 is formed in the recess 22 of the rotor 2 and the lower end 13 a of the rotating shaft 13.

  The plurality of pins 24 are arranged at positions having equal intervals in the circumferential direction, and have a function of transmitting the rotational force of the rotating shaft 13 to the rotor 2. The spacer member 15 is formed with a first insertion hole 15a through which the fastening member 23 is inserted, and a plurality of second insertion holes 15b provided to allow a plurality of pins 24 to be inserted therethrough. Here, four second insertion holes 15b and four pins 24 are provided, but the number is not limited to four.

  Since the rotating shaft 13 and the rotor 2 are fastened by the fastening member 23 with the spacer member 15 being sandwiched, the axial position of the rotor 2 with respect to the stator 3 can be more reliably fixed. Therefore, it is realized that the gap between the rotor 2 and the stator 3 is in an appropriate state. That is, it is possible to appropriately attach the spacer member 15 having the above-described merit.

  In addition, since a plurality of pins 24 are used as a mechanism for transmitting the rotational force from the rotating shaft 13 to the rotor 2, the circumferential balance can be improved compared to a mechanism including a keyway and a key, that is, A well-balanced rotation of the rotating shaft 13 and the rotor 2 is realized. Therefore, it is possible to prevent a deviation due to a portion in the dispersion force between the rotor 2 and the stator 3, that is, to achieve uniform and appropriate dispersion processing. Further, since the occurrence of bias can be prevented, stable dispersion processing can be realized even if the gap is reduced. Furthermore, high-speed rotation is possible, and appropriate distributed processing is realized.

  The stator 3 is formed in a larger shape than the rotor 2 on a plane facing the rotor 2. That is, the stator 3 is configured so that the shape in a plane orthogonal to the axial direction D1 is larger than that of the rotor 2. In the stator 3, a cooling groove portion 26 for flowing a cooling liquid is formed on a surface (upper surface) opposite to the surface (lower surface) facing the rotor 2. The cooling groove 26 is formed so as to be located outside the rotor 2.

  The cooling groove 26 can be cooled to the outermost periphery of the rotor 2 by being formed up to a portion extending to the outside of the rotor 2. That is, the cooling groove 26 can cool the entire dispersion region of the rotor 2 and the stator 3. Therefore, heat generation of the material (mixed mixture 4) can be reliably suppressed. As a result, the material to be dispersed can be prevented from being altered, and the material can be safely dispersed even if the material to be dispersed volatilizes and ignites. In general, the rotor 2 and the stator 3 are formed to have the same size in the opposing surfaces, and in this case, it is difficult to cool the outermost periphery. Since the outermost peripheral portion has the largest amount of heat generation, the cooling groove portion 26 described here can obtain an excellent cooling effect. Therefore, an appropriate dispersion process is realized in an appropriate temperature range.

  The cooling groove 26 is provided with a wall 27 formed along the radial direction (FIG. 4B, etc.). The cooling groove 26 is provided with a cooling liquid supply port 28 and a cooling liquid discharge port 29 at a position sandwiching the wall 27. The cooling liquid supplied from the cooling liquid supply port 28 to the cooling groove 26 is one direction in the circumferential direction D2 in the cooling groove 26 and the wall 27 is not provided from the cooling supply port 28. It flows toward D3. Then, the cooled cooling liquid is discharged from the coolant discharge port 29. The cooling liquid is, for example, water.

  In the cooling groove 26, the cooling water is configured to flow in one direction from the cooling supply port 28 toward the cooling discharge port 29. In other words, the cooling water flows in one direction. Since it is partitioned off by the wall 27, the cooling water is sequentially discharged. That is, if the cooling water is not configured to flow in one direction, the cooling water partially accumulates, and a portion in which the cooling water does not replace in the cooling groove portion may occur, and the cooling function may be deteriorated. There is. On the other hand, the cooling groove 26 is configured so that the cooling water is sequentially replaced, and thus has a high cooling function at all times. Therefore, an appropriate dispersion process is realized in an appropriate temperature range.

  The cooling groove portion constituting the first dispersing device 1 and the stator 3 provided with the cooling groove portion are not limited to the cooling groove portion 26 described above, and include, for example, cooling groove portions 71 and 72 as shown in FIG. The stators 76 and 77 may be used. FIG. 5A shows an example in which the groove is formed as wide as possible while avoiding the screw portion to enhance the cooling effect. FIG. 5B is an example in which a finer groove is formed on the bottom surface of the formed groove portion to increase the contact surface area of the cooling water and enhance the cooling effect. FIG. 5C is a cross-sectional view taken along the line A6-A6 of FIG. 5B, illustrating the cross-sectional shape of the recess 72a that is a fine groove. Since the stators 76 and 77 have the same structure and function as the stator 3 except for the structure of the cooling groove, the description of the same parts is omitted.

  As shown in FIG. 5, like the cooling groove 26, the cooling grooves 71 and 72 are formed on the upper surface side of the stators 76 and 77 formed in a larger shape than the rotor 2, and are positioned outside the rotor 2. It is formed as follows. Wall portions 73 and 74 similar to the wall portion 27 are also provided in the cooling grooves 71 and 72. About the structure similar to the groove part 26 for cooling, it has an effect similar to the groove part 26 for cooling.

  Next, a configuration different from the cooling groove 26 will be described. The cooling groove 71 is provided so as to extend to the very outer periphery of the stator 76, and a protrusion 71a is formed in a portion where the bolt hole 3b is formed. The cooling effect is increased by the amount expanded in the outer circumferential direction. The cooling groove 72 has a plurality of recesses 72a formed in the circumferential direction at the bottom. Since the recess 72a is formed, the amount of heat exchange between the cooling water and the stator 77 is increased, and the cooling effect is enhanced. The cooling grooves 71 and 72 have a higher cooling effect than the cooling groove 26. As described above, even when the stator having the cooling groove portions 71 and 72 is used instead of the cooling groove portion 26, it has a high cooling function and realizes an appropriate dispersion process in an appropriate temperature range.

  Incidentally, the stator 3 is provided with a rotation shaft insertion hole 31 through which the rotation shaft 13 is inserted, and the mixture 4 is guided between the stator 3 and the rotor 2 from a position outside the rotation shaft insertion hole 31 of the stator 3.

  Specifically, the stator 3 is provided with a through hole 32 for supplying a mixture provided at a position outside the rotation shaft insertion hole 31. In other words, the through hole 32 is provided at a position having a predetermined distance from the rotation shaft insertion hole 31. The stator holding portion 18 is provided with a mixture supply port 33 and a communication passage 34 communicating from the mixture supply port 33 to the mixture supply through-hole 32 provided in the stator 3. The mixture 4 supplied from the mixture supply port 33 is guided between the stator 3 and the rotor 2 through the communication passage 34 of the stator holding portion 18 and the through hole 32 of the stator 3. At the end of the mixture supply port 33, a joining flange or the like is formed, and the pipe 130 is connected.

  With this configuration, if the rotor 2 is rotated during the supply of the mixture, the mixture 4 supplied to the through-hole 32 is guided to the outside by centrifugal force, so that the mixture 4 does not reach the vicinity of the rotation center. Accordingly, it is not necessary to provide a sealing device such as a mechanical seal in the rotation shaft insertion hole (also referred to as “first rotation shaft insertion hole”) 31 and a second rotation shaft insertion hole 36 described later. In other words, the through hole 32 is disposed at a position having a distance between the rotation shaft insertion hole 31 and a distance that prevents the mixture 4 guided to the outside by centrifugal force from flowing into the rotation shaft insertion hole 31. Thereby, the apparatus configuration can be simplified. Replacement due to deterioration of the seal part can be eliminated.

  Here, the mixture supply port 33 and the communication passage 34 are formed to be inclined so as to be directed in the direction D4 toward the center side in the radial direction as going downward, for example, as going downward. It may be formed to be inclined so as to face the tangential directions D5 and D6. The mixture supply port 33 and the communication path 34 are formed at a position where the communication path 34 is connected to the through hole 32 at the lower end thereof. Thereby, the through hole 32 can be brought closer to the rotation shaft insertion hole 31.

  The stator holding portion 18 is provided with a second rotation shaft insertion hole 36 through which the rotation shaft 13 is inserted. The second rotating shaft insertion hole 36 is provided with a labyrinth structure seal portion 37 that is a non-contact seal. Here, the labyrinth structure means that one or a plurality of concave portions and / or convex portions are formed on one or both of the rotary shaft side (rotary shaft 13) and the fixed portion side (stator holding portion 18). In this structure, uneven spaces are sequentially formed between the fixing portion and the labyrinth structure. The dimension of each recessed part and each convex part is about 0.01-3.00 mm, for example.

  Air is supplied from the outside of the stator holding portion 18 to the space 38 communicating with the upper side of the second rotation shaft insertion hole 36 in the stator holding portion 18. An air purge seal mechanism 39 that performs an air purge seal function by supplying air from the outside of the stator holding portion 18 is provided. The air purge seal mechanism 39 includes, for example, a space 38 formed by the bearing holding portion 17 and the stator holding portion 18, a purge passage 39b provided in the bearing holding portion 17 and connecting the space 38 and the outside, and a purge passage 39b. And an air supply unit 39a for supplying purge air. The air purge seal mechanism 39 supplies the air supplied from the air supply part 39a to the gap portion between the second rotary shaft insertion hole 36 and the rotary shaft 31 via the purge passage 39b and the space 38, as indicated by an arrow F1. . This air creates a sealing function.

  A mounting recess 18 f for the bolt 3 a for mounting the stator 3 to the stator holding portion 18 is formed outside the second rotating shaft insertion hole 36 of the stator holding portion 18. Moreover, the inner peripheral part 18g which forms the 2nd rotating shaft insertion hole 36 is made into the shape which protrudes by forming the recessed part 18f. The rotating shaft 13 has a protruding portion 13g formed so as to protrude above the inner peripheral portion 18g of the stator holding portion 18. As indicated by the arrow F1, the air supplied from the air supply part 39a passes between the inner peripheral part 18g and the projecting part 13g, and enters the gap part between the second rotary shaft insertion hole 36 and the rotary shaft 31. Supplied.

  The labyrinth structure of the seal part 37 realizes enhancing the shaft sealing effect of the second rotation shaft insertion hole 36, and the air purge seal mechanism 39 has an air purge function to prevent the rotation shaft insertion hole 31 and the second rotation shaft insertion hole 36. Realize the shaft seal effect of the part. As described above, in the first dispersion apparatus 1, the position where the mixture 4 is guided is devised and the centrifugal force is used. Therefore, the labyrinth structure and the air purge function are not necessarily provided. However, it is possible to enhance the shaft seal effect by providing at least one of them, and it is possible to realize a further shaft seal effect by providing both.

  The container 11 includes a conical wall 42 whose cross-sectional area decreases toward the lower side, a cylindrical wall 43 positioned on the conical wall 42, and a drain provided below the conical wall 42. And an outlet 44. The discharge port 44 is provided at the lower end of the container 11 and discharges the mixture 4 that has been dispersed. A flange for connection or the like is formed at the end of the discharge port 44, and the pipe 140 is connected thereto. Since the mixture 4 after the dispersion treatment is discharged through the conical wall surface 42, the amount of the mixture 4 that adheres to the inner wall and is not discharged is drastically reduced. Therefore, the yield is improved and appropriate processing is realized. In addition, you may make it provide the container 11 with a vacuum pump, and it can reduce mixing of the air to the mixture 4 by doing so.

  The container 11 is provided with a cooling mechanism 41 having a cooling function. The cooling mechanism 41 includes, for example, a wall surface 42 and a wall surface 43 which are outer surfaces of the container 11, a space forming member 45 formed on the outer side so as to cover the outer surface (the wall surface 42 and the wall surface 43), and a cooling medium supply It has a port 46 and a cooling medium discharge port 47. The space forming member 45 is a member also called a jacket, for example, and forms a space 48 that can be filled with a cooling medium such as cooling water between the wall surfaces 42 and 43.

  The cooling medium supply port 46 is disposed at, for example, the lower side of the space forming member 45 and supplies cooling water to the space 48. The cooling medium discharge port 47 is disposed, for example, at the upper part of the side surface of the space forming member 45 and discharges cooling water from the space 48.

  With such a configuration, the cooling mechanism 41 has a function of cooling the inside of the container 11 through the wall surfaces 42 and 43. The cooling mechanism 41 makes it possible to cool the mixture 4 that has been subjected to the dispersion treatment. Moreover, when the material which volatilizes easily is used for the mixture 4, it can return to a liquid by cooling the volatilized material. The configuration of the cooling mechanism 41 is not limited to the above, and may be a known configuration.

  In addition, the container which comprises the 1st dispersion | distribution apparatus 1 is not restricted to the container 11 mentioned above, For example, the containers 81 and 86 as shown in FIG. 6 may be sufficient. First, the container 81 shown in FIG. The container 81 has the same configuration and function as the container 11 described above, except that the container 81 has a stirring mechanism 82. Explanation of similar parts is omitted.

  A container 81 in FIG. 6A has wall surfaces 42 and 43 and a discharge port 44. The container 81 is provided with a cooling mechanism 41. The container 81 is provided with a stirring mechanism 82. The stirring mechanism 82 scrapes off the slurry-like mixture 4 attached to the inner surfaces of the wall surfaces 42 and 43. The scraped mixture 4 is discharged from the discharge port 44 together with the mixture 4 not adhered. The stirring mechanism 82 includes a stirring plate 82a formed in a shape along the wall surfaces 42 and 43, and a motor 82b that rotationally drives the stirring plate 82a. The stirring mechanism 82 also has a rotating shaft 82c and a bearing 82d. The stirring plate 82a is formed so that the gap between the stirring plate 82a and the wall surfaces 42 and 43 is about 0 to 20 mm. As the stirring plate 82a, a metal or a metal to which a resin is attached is used. Here, the stirring plate 82a is configured to have two stirring portions 82e shaped so as to be scraped off at two circumferential positions, but the stirring portion 3 is formed by combining a plurality of plate members. The number may be increased to one or more. In the example of FIG. 6A, a connection pipe 83 is attached to the discharge port 44 because of the necessity of providing the rotation shaft 82 c, and is connected to the pipe 140 through this. Since the mixture 4 after the dispersion treatment is discharged through the conical wall surface 42, the amount of the mixture 4 that adheres to the inner wall and is not discharged is drastically reduced, and further, the discharge of the mixture 4 is promoted by the stirring plate 82a. Therefore, the yield is improved.

  Next, a container 86 shown in FIG. 6B will be described as still another example of the container constituting the first dispersing device 1. The container 86 is a container that also serves as a post-treatment storage tank that stores the dispersion-processed mixture 4. That is, the container 86 has, for example, a cylindrical wall surface 86a and a curved bottom surface portion 86b below this, and a discharge port 86c is provided at the lower end portion of this bottom surface portion 86b via an on-off valve 86d. It has been.

  The container 86 shown in FIG. 6B is compatible with, for example, a small amount of the mixture 4 that needs an appropriate dispersion process and is expensive. After the dispersion treatment, the container 86 can be removed from the cover unit 12, the rotor 2 and the stator 3 attached thereto by removing the bolt 11d. Thereby, in the case of other structures, the mixture 4 that adheres to the outer wall of the first dispersing device can also be collected, and the yield is improved. The shape of the container 86 that also serves as a post-treatment storage tank is not limited to this, and may have a conical wall surface, and a larger tank shape so that a large amount of dispersion processing is possible. Further, it may be a large size and, for example, a shape that can be divided into two. Further, the cooling mechanism 41 may be provided in a container that also serves as a post-treatment storage tank.

  Moreover, as materials of the rotor 2 and the stator 3 constituting the first dispersing device 1, for example, stainless steel such as SUS304, SUS316, SUS316L, and SUS430 of Japanese Industrial Standard (JIS), or carbon steel such as JIS S45C and S55C. May be used. Further, ceramics such as alumina, silicon nitride, zirconia, sialon, silicon carbide, and tool steels such as JIS SKD and SKH may be used. You may make it use what thermally sprayed ceramics (for example, alumina thermal spraying, zirconia thermal spraying) to metal materials, such as stainless steel. By using a roller and a stator using ceramics, and a rotor and stator in which a ceramic material is sprayed on a metal material, the service life is extended and metal contamination (contamination) can be prevented.

  In the preliminary dispersion method using the first dispersion device 1 as described above, the mixture 4 is supplied between the rotor 2 and the stator 3 of the first dispersion device 1 and passed toward the outer periphery by centrifugal force. scatter. The first dispersion apparatus 1 and the preliminary dispersion method have a good yield, a high dispersion power, and realize a dispersion process in an appropriate temperature range, that is, an appropriate preliminary dispersion process. Further, the first dispersion apparatus 1 and the preliminary dispersion method can be easily cleaned because the container 11 and the cover unit 12 can be separated when cleaning after the dispersion treatment.

  As described so far, in the first dispersing device 1, the distance between the rotor 2 and the stator 3 that perform shearing dispersion can be finely adjusted, and the distance can be fixed reliably. Furthermore, the rotor 2 can be rotated in a well-balanced manner to achieve uniform dispersion processing. Therefore, for example, the coarsely dispersed mixture 4 containing coarse particles of several hundred μm to 1000 μm can be surely predispersed.

  In the first dispersion apparatus 1, the distance between the rotor 2 and the stator 3 is preferably 10 μm or more and 1000 μm or less. If the thickness is less than 10 μm, the rotor 2 and the stator 3 come into contact with each other due to thermal expansion due to heat generation during dispersion, and the possibility of breakage increases. When it exceeds 1000 μm, it is difficult to reduce the solid particles. When the distance between the rotor 2 and the stator 3 is 10 μm or more and 1000 μm or less, the solid particles are reduced to some extent while suppressing the risk of damage to the device, for example, until the average particle size becomes several tens μm or less, preferably 10 μm or less. It can be done efficiently until

  A shear type third dispersing device (not shown) may be provided between the coarse dispersing device 110 and the first dispersing device 1. In that case, for example, in the third dispersion apparatus, the distance between the rotor and the stator is set to 1000 μm, and the solid particles in the mixture 4 are dispersed to 100 μm or less. In the first dispersion apparatus 1, the distance between the rotor 2 and the stator 3 is dispersed. Is 100 μm, and the solid particles in the mixture 4 can be dispersed to 10 μm or less and supplied to the second dispersion device 60. That is, even if the mixture 4 supplied from the coarse dispersion device 110 contains coarse solid particles, the preliminary dispersion can be reliably performed in a short time.

  Furthermore, in the 1st dispersion | distribution apparatus 1, since the mixture 4 is disperse | distributed by a shearing type, it can disperse | distribute uniformly. That is, since the mixture 4 passes between the rotor 2 and the stator 3, the shear force between the rotor 2 and the stator 3 acts on all the mixtures 4. Therefore, the shearing force received by the mixture 4 does not vary locally (so-called short path), and the dispersion efficiency increases.

  3 to 6 described as the first dispersion device can be used for nano-dispersion as the second dispersion device 60 depending on the mixture 4. That is, the distance between the rotor 2 and the stator 3 of the shearing type dispersion device 1 is set narrow and used for nano dispersion. A dispersion treatment system comprising a shearing dispersion device 1 as a first dispersion device and a shearing dispersion device 1 as a second dispersion device in which the distance between the rotor 2 and the stator 3 is narrower than this device is efficiently reserved. Nano-dispersion treatment can be performed by dispersing.

  Next, a modified example of the distributed processing system 100 will be described with reference to FIGS. FIG. 7 is a schematic diagram showing a distributed processing system 102 suitable for multi-path distributed processing. The distributed processing system 102 has the same configuration and functions as those of the system 100 described above except that the composite processing system 102 can be combined.

  The distributed processing system 102 shown in FIG. 7 includes a coarse dispersion device 110, an intermediate tank 112, a first dispersion device 1, a second dispersion device 60, and a storage tank 120. A pipe 134 is connected to the intermediate tank 112 and the coarse dispersion device 110 from the downstream side of the pump 142 of the pipe 140. A pipe 136 is connected to the upstream side of the pump 132 in the pipe 130 from the intermediate tank 112. Therefore, after the mixture 4 preliminarily dispersed in the first dispersing device 1 is stored in the intermediate tank 112, it can be returned to the first dispersing device 1 and used for repeating the predispersion. Further, the mixture 4 preliminarily dispersed by the first dispersing device 1 may be returned to the coarse dispersing device 110. That is, according to the dispersion processing system 102, it is possible to easily reduce the average diameter of solid particles, for example, to 10 μm or less from coarse particles by repeating the preliminary dispersion.

  Similar to the distributed processing system 100, the distributed processing system 104 illustrated in FIG. 8 includes a coarse dispersion device 110, a first dispersion device 1, a second dispersion device 60, and a storage tank 120. Note that a pump is not installed in the pipe 130. A compressor 160 is connected to the coarse dispersion device 110 via a flow rate adjustment valve 162 and a filter 164. That is, the flow rate adjustment valve 162 and the filter 164 are provided in the pipe 166 connecting the coarse dispersion device 110 and the compressor 160. The flow rate adjusting valve 162 adjusts the flow rate of the compressed air guided from the compressor 160 to the coarse dispersion device 110. The filter 164 removes unnecessary substances in the compressed air guided from the compressor 160 to the coarse dispersion device 110.

  The dispersion treatment system 104 coarsely disperses powder and liquid without applying pressure, and then from the coarse dispersion device 110 by the pressure applied to the mixture 4 in the treatment dispersion device 110 by the compressor 160 and the flow rate adjustment valve 162. The mixture 4 is guided to the first dispersing device 1 via the pipe 130.

  Next, a distributed processing system 106 shown in FIG. 9 will be described as still another example of the distributed processing system. The dispersion processing system 106 has an excellent function of mixing powder into the liquid which is difficult to mix with the liquid, so that it floats on the surface of the liquid or becomes a lump (a large lump that is agglomerated and solidified by sucking the liquid). The coarse dispersion apparatus 170 is characterized in that it has the same configuration and function as the distributed processing system 100 except that the coarse dispersion apparatus 170 is provided instead of the coarse dispersion apparatus 110 of the distributed processing system 100 of FIG. . Explanation of similar parts is omitted.

  The coarse dispersion apparatus 170 includes a liquid supply unit 111 and a powder supply unit 112. The coarse dispersion device 170 includes a stirring blade 173, a rotating shaft 177 connected to the stirring blade 173, and a driving device 178 such as a motor that rotates the rotating shaft 177. The rotating shaft 177 is eccentric from the center of the coarse dispersion device 170 (arranged at a position shifted from the center), and an inclined vortex is generated by the rotation of the stirring blade 173. The coarse dispersion device 170 has, for example, a cylindrical side wall portion and a curved bottom surface portion, but is not limited thereto.

  The powder supply unit 112 puts the powder material P into the inclined vortex generated by the stirring blade 173. The powder supply unit 112 is, for example, a vibration type quantitative feeder. The powder supply unit 112 is not limited to this, and may be another vibratory feeder or a screw feeder. The powder charged into the inclined vortex is prevented from becoming a large lump. Therefore, it is dispersed by the coarse dispersion device 170 without being hardened. In addition, by adopting a configuration in which the stirring blade 173 is rotated at a position shifted from the center, a wide space for supplying the raw materials from the liquid supply unit 111 and the powder supply unit 112 can be secured. Moreover, the above-mentioned effect also has the advantage that the accuracy of the blending ratio of the mixture 4 is increased.

  As described above, according to the distributed processing systems 100, 102, 104, 106, the mixture 4 is predispersed by the first dispersing device 1, and the predispersed mixture 4 is nanodispersed by the second dispersing device 60. Solid particles can be efficiently miniaturized to a nano-level size.
