[Prior Art] The so-called wet dispersion treatment refers to a treatment in which particles contained in a liquid are pulverized to form finer fine particles. It is often used in a wide range of fields such as inks, paints, ceramic microparticles, metals, inorganic materials, and pharmaceuticals. As one of the dispersers used in these processes, there is a media agitating type disperser. This disperser stirs the treatment liquid together with the medium in the container, and pulverizes and disperses the particles by the shearing force of the medium. The dispersion which has been treated is separated from the medium by a separator provided in the container, and then discharged to the outside of the container. As the separator, a sieve type separator such as a lid type or a screen type is often used. In such a dispersion treatment, the particle diameter after the treatment has a large influence on the medium diameter. That is, in order to form a dispersion of fine particles, it is necessary to use a medium having a small diameter. In the past, most of the media having a diameter of 〇.3 mm or more were used. In this case, the average particle diameter of the fine particles of the dispersion obtained is usually 10 nm (nm) or more. It is difficult to form fine particles of less than 100, and it takes a very long time even in the case of -4 - (2) (2) 1355290 which may be made. Therefore, it has been found that a method of dispersing fine particles into a dispersion having an average particle diameter of less than 100 nm is obtained by using a medium having a diameter of 0.2 mm or less. For example, Patent Document 1 describes a method of producing a dispersion using a minute bead having a diameter of 〇2 mm or less as a medium. The material of the medium is ceramic, hard glass, hard plastic, metal or metal compound. However, when the diameter of the medium becomes small, a separator for separating the dispersion from the medium causes a problem. This is because the gap of the mesh of the screen needs to be made 1/3 or less of the medium diameter in the cover type or the screen type. Therefore, it becomes difficult to make a separator. Further, problems such as biting, clogging, and the like often occur, and stable continuous operation cannot be performed. Further, there has been a demand for a dispersion treatment in which a particle diameter is formed into a nanometer shape in recent fields. Therefore, in the medium agitation type wet disperser, it is required to further make the diameter of the medium 0.1 mm or less. However, when the diameter of the medium is so small, it is almost impossible to use a screen type such as a lid type or a screen type. Therefore, separators that are required to be different from these are required. As a separator for solving such a problem, a centrifugal separator that separates a medium from a dispersion by centrifugal force has been proposed (for example, Patent Document 2). This centrifugal separator is a centrifuge in which a plurality of circular plates are arranged at a certain interval on a rotating shaft, and a plurality of blades are arranged in a cylindrical shape between the two circular plates. However, the "disintegrator" pulverizing blade also serves as a separating blade. Therefore, it is difficult to adjust the balance between the pulverizing function and the grading function. Therefore, there is a problem that the performance of both parties cannot be fully utilized. -5- (3) (3) 1355 290 [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. An object of the present invention is to economically carry out a dispersion treatment in which a particle diameter is formed into a nanometer shape. Therefore, a medium agitation type wet disperser capable of using a medium having a diameter of 〇.1 mm or less is provided. And a medium agitating wet disperser that provides stable continuous operation. Further, a medium agitating type wet disperser capable of reliably separating fine particles from a medium is provided. Further, a medium agitation type wet disperser having excellent fine particle classification performance is provided. [Means for Solving the Problem] In the medium agitation type wet disperser according to the first aspect of the present invention, the medium agitation type wet disperser of the present invention has a cylindrical dispersion tank whose one end is closed and is inserted into the dispersion tank. a tubular rotating shaft that is rotatably provided on the other end side, and an outer rotor that includes a plurality of blades arranged in a cylindrical shape and that is rotated by the rotation shaft to generate centrifugal force, and is located inside the outer rotor and has a plurality of blades arranged in a cylindrical shape, an inner rotor that generates centrifugal force by being rotated by the rotation shaft, and the dispersion groove includes a supply port that communicates the inside and the outside of the dispersion groove, and the tubular rotation shaft communicates with the inner rotor The inside is formed to form a discharge port.

The medium agitation type wet disperser according to claim 2, wherein the outer rotor located in the reinforcing chamber has a plurality of protrusions on the outer peripheral portion. The medium agitation type wet disperser according to any one of claims 1 to 3, wherein the plurality of blades of the outer rotor are provided, The plurality of blades of the inner rotor are closer to the position of the one end of the dispersion groove than the plurality of blades of the inner rotor. The medium agitation type wet disperser according to any one of claims 1 to 4, wherein the supply port is set in the aforementioned dispersion tank. another side. The medium agitation type wet disperser according to any one of claims 1 to 5, wherein the dispersion tank is provided with a cooling cover on the outer side thereof. . According to the present invention, the outer rotor has the function of pulverizing and dispersing solid particles. Further, the inner rotor has a function of separating the medium and a function of classifying the fine particles. A circulating flow that circulates inside and outside the outer rotor is formed in the dispersion tank, and the treatment liquid flows together with the medium. The particles are pulverized and dispersed during this cycle. Further, the treatment liquid is classified in the inner rotor, and only the fine particles are discharged through the inner rotor. The large particles and the medium are returned to the circulation flow again. As a result, the disperser of the present invention forms a function of pulverization and dispersion of the outer rotor (5) (5) 1355290, separation from the inner rotor, and grading function. Moreover, even if a medium having a diameter of 0.1 mm or less is used, problems such as clogging do not occur, and stable continuous operation can be performed. Therefore, the dispersion process of making the particle diameter into a nanometer shape can be performed economically. [Embodiment] Hereinafter, embodiments of the present invention shown in the drawings will be described. Fig. 1 and Fig. 2 show a first embodiment of the medium agitation type wet disperser of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic cross-sectional view of a wettering type wet disperser, and Fig. 2 is a schematic cross-sectional view taken along line A-A of Fig. 1. This medium puddle type wet disperser 1 is constituted by a dispersion tank 2, a rotating shaft 3', an outer rotor 4, an inner rotor 5, and the like. The dispersion tank 2 is a cylindrical container whose one end is closed. At the other end, the cover member 22 is attached via the flange 21, and the other end portion is substantially closed. Further, the attachment position of the supply port 23 provided in the dispersion tank 2 is preferably in the vicinity of the other end of the dispersion tank 2. As shown in the figure, it is particularly preferable to provide the cover member 22. This is because it is easy to install according to the positional relationship between the circulation flow and the discharge port, which will be described later. The cover member 22 is formed substantially in a cylindrical shape, and the tubular rotating shaft 3 is rotatably provided at the axial center. A shaft seal 34 is interposed between the outer peripheral surface of the rotary shaft 3 and the inner peripheral surface of the cover member 22 to seal the dispersion tank 2. The rotary shaft 3 has a tubular shape in which the hollow portion 31 is formed at its axial center, and is inserted through the other end of the dispersion -8-8, 1355290 (6) groove 2, and is disposed coaxially with the dispersion groove. In the dispersion tank 2, the outer rotor 4 and the inner rotor 5 are attached to the other end of the rotating shaft 3. Further, the other end of the rotary shaft 3 is located outside the dispersion tank 2, and a driving device (not shown) is attached. The outer rotor 4 is a cylindrical portion 42 on one surface of the disk-shaped holding portion 41, and the tubular portion 42 is composed of a plurality of blades 43 arranged in a cylindrical shape at regular intervals. The open end is located on one end side of the dispersion tank 2, and the other end closed by the holding portion 41 is attached to the rotary shaft 3 by the key 45 at the other end side of the dispersion tank 2. Therefore, when the outer rotor 4 is rotated in the direction of the arrow of the figure, the centrifugal force is generated by the blades 43. Then, the treatment liquid passes through the opening 44 between the blades 43, and flows from the inside toward the outside. As a result, the treatment liquid and the medium 7 in the dispersion tank 2 form a circulation flow, that is, the outer side of the vane 43 flows toward the one end side from the other end side, and flows from the outer side toward the inner side at the open end, and the vane The inner side of 43 flows from one end side toward the other end side. Further, by the rotation of the outer rotor 4, the treatment liquid in the dispersion tank 2 is stirred in the same manner as the medium 7. Then, the pulverization and dispersion treatment are carried out by the shearing force generated between the inner wall of the dispersion tank 2 and the vane 43. At the same time, the whole process is satisfactorily stirred by the circulation of the treatment liquid to the inside and outside of the outer rotor 4, and the entire treatment liquid is uniformly treated. The inner rotor 5 is located inside the outer rotor 4 and includes a tubular portion 52'. The tubular portion 52 is composed of a plurality of blades 53 arranged in a cylindrical shape at a constant interval on one surface of the disk-shaped holding portion 51. In a state in which the opened end of the tubular portion 52 is in close contact with the surface of the holding portion 41 of the outer rotor 4, (7), (7) 1355290 is fixed to the rotating shaft 3 by bolts 55. The outer peripheral surface of the vane 53 is located at a position slightly separated from the inner peripheral surface of the vane 43 of the outer rotor 4, and the gap between the outer peripheral surface of the vane 53 and the inner peripheral surface of the vane 43 is formed in the outer rotor 4 as described above. The flow path of the inside and the outside of the circulation flow is formed to flow from the one end side of the dispersion tank 2 toward the other end side. Further, the inner peripheral surface of the vane 53 is located slightly apart from the outer surface of the rotary shaft 3, and a space portion 56 is formed inside the vane 53. The rotary shaft 3 is provided with an opening 32 at a position of the space portion 56, and the hollow portion 31 communicates with the space portion 56. As a result, the hollow portion 31 of the rotary shaft 3 forms the discharge port 33 of the dispersion liquid. In other words, in the above-mentioned circulation flow, the dispersion liquid subjected to the pulverization and dispersion treatment flows into the space portion 56 via the inner peripheral wall 54 between the blades 53, and is discharged from the discharge port 33. Similarly to the outer rotor 4, the inner rotor 5 generates a centrifugal force by the blades 53 when it is rotated in the direction of the arrow shown. Therefore, the separation function and the classification function are exerted on the particles passing through the opening 54. That is, the particles or the medium 7 having a large particle diameter do not flow into the space portion 56, and only the fine particles are discharged through the space portion 56. Further, the large particles and the medium 7 which have not flowed into the space portion 56 are immediately returned to the circulation flow formed inside and outside the outer rotor 4. Then, it is pulverized and dispersed again. Therefore, the dispersion treatment and the classification treatment can be surely performed. Since the inner rotor 5 is located inside the outer rotor 4, the vanes 53 and the vanes 43 are formed at substantially the same position in the axial direction. Thereby, the large particles separated by the inner rotor 5 can be quickly returned to the circulating flow of the outer rotor 4. -10 - (8) (8) 1355290 Further, it is preferable that the vane 43 is disposed closer to one end of the dispersing groove 2 than the vane 53. This is because the gap between the outer peripheral surface of the vane 53 and the inner peripheral surface of the vane 43 is a flow path of the circulating flow, and the flow from the one end side of the dispersing groove 2 toward the other end side is formed. Therefore, in the case where the blade 43 is closer to one end of the dispersion groove 2 than the blade 53, the blade 43 is located on the upstream side of the circulation flow, and the blade 53 is located on the downstream side of the circulation flow. Therefore, after the upstream blades 43 separate large particles in advance, the downstream blades 53 are finally separated and classified, and effective treatment can be performed, and the treatment liquids such as the dispersion tank 2, the outer rotor 4, and the inner rotor 5 can be formed. The member that is in direct contact with the wear resistance is preferably a material, and a ceramic such as alumina, alumina-zirconia, tantalum carbide or the like is preferably used. Thereby, impurities can be prevented from being mixed into the product. The medium agitation type wet disperser 1 of the present invention is capable of performing a strong stirring operation in the narrow dispersion tank 2. Therefore, as shown in the figure, the cooling cover 6 is provided outside the dispersion tank 2, and it is preferable to forcibly cool the dispersion tank 2. The cooling cover 6 covers the entire dispersion tank 2 as much as possible, and the water supply port 61 and the water discharge port 62 are provided in consideration of the fact that the cooling water does not deflect. The temperature management of the treatment object can be performed by the outer cover 6. Further, it may be used as a heating cover immediately after the treatment or the like. Next, Fig. 3 and Fig. 4 show a second embodiment of the medium agitation type wet disperser of the present invention. Fig. 3 is a schematic cross-sectional view of the medium agitation type wet disperser, and Fig. 4 is a schematic cross-sectional view taken along line B-B of Fig. 3. This medium agitation type wet disperser 101 is constituted by a dispersion tank 102, a rotating shaft 1103, a shaft 103, an outer rotor 104, an inner rotor 105, and the like. In order to reinforce the dispersing function, the dispersing tank 102 is provided with a reinforcing chamber 181 on one end side thereof. That is, the dispersing groove 102 is formed by a circular main chamber 182 and a reinforcing chamber 181 having a circular cross section.
具體而言，由位於同軸上的內筒121與外筒122所構成 的雙重圓筒的一端彼此受到端板123所封閉。又，內筒121 的另一端在外筒122內受到端板124所封閉。且，在外筒 122的另一端經由突緣125安裝著蓋構件126，外筒122的另 一端實質上被封閉著。如此，在雙重圓筒的部分形成剖面 呈環狀的補強室181，僅在外筒122的部分形成剖面呈圓形 的主室182。 蓋構件126大致形成圓筒狀，在軸心，管狀的旋轉軸 103可自由旋轉地被設置著。在旋轉軸103的外周面與蓋構 件126的內周面之間介裝軸密封件133，可將分散槽1〇2密 閉。Specifically, one end of the double cylinder constituted by the inner cylinder 121 and the outer cylinder 122 which are coaxially closed is closed by the end plate 123. Further, the other end of the inner cylinder 121 is closed by the end plate 124 in the outer cylinder 122. Further, a cover member 126 is attached to the other end of the outer cylinder 122 via a flange 125, and the other end of the outer cylinder 122 is substantially closed. Thus, the reinforcing chamber 181 having a circular cross section is formed in the portion of the double cylinder, and the main chamber 182 having a circular cross section is formed only in the portion of the outer cylinder 122. The cover member 126 is formed substantially in a cylindrical shape, and a tubular rotating shaft 103 is rotatably provided at the axial center. A shaft seal 133 is interposed between the outer peripheral surface of the rotary shaft 103 and the inner peripheral surface of the cover member 126 to seal the dispersion groove 1〇2.
旋轉軸103爲在其軸心形成中空部131的管狀，與補強 室181及主室182同軸地設置著。旋轉軸103的一端是位於 主室1 8 2，安裝著外側轉子1 〇 4及內側轉子1 〇 5。又，旋轉 軸103的另一端位於分散槽X02的外部，安裝著驅動裝置（ 未圖不）。 外側轉子1〇4是以圓板狀的保持部141與筒狀部142所 構成。而外側轉子104的被開放的一端是位於補強室181， 受到保持部141所封閉的另一端位於主室182，藉由鍵146 安裝於旋轉軸1 0 3。 -12- (10) (10)1355290 筒狀部142的一端位於補強室181的端板123的附近。 藉此，剖面形成環狀的補強室181被區分成內外的2個區域 ，可有效地進行攪拌。 又，位於主室182的筒狀部142是與第1實施形態（圖1 、2)的情況同樣地，以一定的間隔將複數個葉片144排列 成筒狀。 因此，當使外側轉子104朝圖的箭號方向旋轉時，藉 由葉片144產生離心力。然後，處理液通過葉片144間的開 口 145，由內側朝外側流動。其結果，分散槽1〇2內的處理 液及介質107形成循環流。即，在葉片144的外側，由另一 端側朝一端側流動，而在被開放的一端，由外側朝內側流 動，而在葉片144的內側，由一端側朝另一端側流動。 又，藉由外側轉子104的旋轉，使得分散槽1〇2內的處 理液與介質1〇7—同地被攪拌。然後，藉由分散槽102的內 壁與葉片I44之間所產生的剪斷力，承受粉碎、分散處理 。又同時’藉由處理液循環於外側轉子104的內外，使得 全體被良好地攪拌，處理液全體被均等地處理。 藉由分散槽102具備補強室181，可飛躍地提昇粉碎、 分散處理的性能。這是由於因補強室181的剖面呈回狀， 使得外側轉子104的內外兩面與分散槽102的內壁接近，可 產生剪斷力之故。 且爲了提昇粉碎、分散性能’外側轉子1〇4在筒狀部 142的外周部設置複數個突起143爲佳。安裝突起143的部 位’亦可設置於同狀部142的內周部或外周部，或內周部 -13- (11) (11)1355290 與外周部雙方。又，亦可與安裝於筒狀部142的突起143相 對向，在補強室181的周壁面（內筒121的外周面或外筒122 的內周面）設置突起（未圖示）。即使在受到微粉碎而增加 處理液的黏性的情況，也可藉由設置這些突起143，將介 質107有效地攪拌。 內側轉子105是位於外側轉子104的內側，在圓板狀的 控制裝置151的一面具備有由以一定的間隔排列成筒狀的 複數個葉片154所構成的筒狀部152。然後，在將筒狀部 152的已被開放的一端密接於外側轉子1〇4的保持部141的 —面的狀態下，藉由螺栓153固定至旋轉軸103。 葉片154的外周面是位於由外側轉子1〇4的葉片144的 內周面稍許分離的位置。而兩葉片間的間隙是如前所述， 成爲形成於外側轉子104的內外的循環流的流路，形成由 分散槽102的一端側朝另一端側的流動。 又，葉片154的內周面位於由旋轉軸103的外表面稍許 分離的位置，在葉片154的內側形成空間部156。旋轉軸 103在空間部156的位置設置開口 132，中空部131與空間部 156連通。其結果，旋轉軸103的中空部131形成分散液的 排出口 134。即，在上述循環流，接受粉碎、分散處理的 分散液是經由葉片154間的開口 132流入到空間部.156，由 排出口 134排出。 內側轉子1 0 5是與外側轉子1 〇 4同樣地，當朝圖所示的 箭號方向旋轉時，藉由葉片154產生離心力。因此，對於 通過開口 155的粒子，形成發揮分離功能及分級功能。即 ⑧， -14- (12) (12)1355290 ，粒徑大的粒子或介質107不會流入到空間部156，僅微粒 子經過空間部1 5 6被排出。 又’未流入到空間部15 6的大粒子及介質107立即被返 回到形成於外側轉子104的內外的循環流。然後，因再次 被進行粉碎、分散處理，所以可確實地進行分散處理及分 級處理。 內側轉子105位於外側轉子104的內側，葉片154與葉 片144是對於軸線方向位於大致相同位置。藉此，能夠迅 速地將受到內側轉子1 05所分離的大的粒子返回至外側轉 子1 0 4的循環流。 又，葉片144設置於較葉片15 4更接近分散槽10 2的一 端的位置爲佳。這是由於葉片154的外周面與葉片144的內 周面之間隙爲循環流的流路，形成由分散槽102的一端側 朝另一端側的流動。因此，在葉片144較葉片154更接近分 散槽102的一端的情況’葉片144位於循環流的上游側，葉 片154位於循環流的下游側。 因此’在上游的葉片144預先將大的粒子分離後，下 游的葉片154進行最終的分離 '分級，可形成有效的處理 之故。 與分散槽102、外側轉子1〇4及內側轉子105等的處理 液直接接觸的構件是耐磨損性的材質爲佳，使用氧化鋁、 氧化鋁·氧化鉻、碳化矽等的陶瓷爲佳。藉此，可防止雜 質混入到製品中。 本發明的介質攪拌型濕式分散機101是能夠在較窄的 -15 - (13) (13)1355290 分散槽102內進行強力的攪拌操作。因此，如圖所示，在 分散槽2的外側設置冷卻用外罩6，將分散槽1〇2強制地冷 卻爲佳。冷卻用外罩1〇6是儘可能地覆蓋分散槽i 02全體， 並且考量冷卻水不會產生偏流地設置供水口 1 6 1及排水口 162。藉由外罩106可進行處理物的溫度管理。又，亦可在 剛進行處理等時，作爲加熱用外罩來使用。 [實施例1] 使用第1實施形態所示的本發明的介質攪拌型濕式分 散機，以以下所示的條件進行將二次凝聚的氧化鈦分散的 試驗，確認其性能。 將已調製好的漿體置入到保持槽，以定量泵浦導入至 分散機的供給口，將由分散機的排出口所排出的漿體再次 返回至保持槽，形成循環系統，在此狀態下起動分散機進 行試驗。 將分散機啓動後，在每個預定的時間，由分散機的排 出口採取樣品。對於粒徑的測定，使用日機裝（股）公司的 粒度分析儀（MICR〇TRAC®)MKIIDRA，根據雷射繞射 '光 散亂法，進行測量。 處理條件 分散機：如圖1及2所示的分散機、外側轉子外徑120mm 馬達：3.7kw、最大旋轉數3,600rpm 介質：氧化锆、直徑〇.〇3mra、 -16 - (14) (14)1355290 使用量〇.84kg 處理物：氧化鈦MT-150W(迪可（TAYCA)製） —次粒子徑15nm、二次凝聚體徑2.3μιη 使用量300g 溶媒：水 使用量2700g 濃度：1 〇wt% 分散劑：娜普可斯帕斯44_c(產品名；Sannopco公司製）、7g 處理量：1公升/分鐘 將兩轉子的旋轉數設爲2070rPm進行運轉，在開始運 轉90分鐘後，獲得平均粒子徑35.8nm的分散液。在分散 液中，未見混入有介質。 [實施例2 ] 將兩轉子的旋轉數變更成1600rpm，其他的條件設成 與實施例相同進行運轉。在開始運轉90分鐘後，獲得平均 粒子徑24.1 nm的分散液。在分散液中，未見混入有介質 〇 其次，使用第2實施形態所示的本發明的介質攪拌型 濕式分散機，以表1所示的條件進行將上述氧化鈦（平均粒 徑2.4μπι)分散的試驗，確認其性能。 將已調製好的漿體置入到保持槽，以定量泵浦導入至 分散機的供給口，將由分散機的排出口所排出的漿體再次 * 17 - (15) 1355290 返回至保持槽，形成循環系統，在此狀態下起動分散機進 行試驗》 表1 實施例3 實施例4 實施例5 分散機 圖3及圖4所示的分散機 外徑轉子徑120mm 處理物名 氧化鈦MT-150W(迪可（TAYCA)製） 處理物量 _3〇〇g_ 濃度 1 0 wt % 溶媒 水 溶媒量 2700g 分散劑 娜普可斯帕斯44-c(產品名；Sannopco公 司製） 分散劑濃度 7fi 旋轉速度 1 600rpm 2 6 4 0 rp m 2 6 4 0 r p m 珠材質 氧化锆 珠徑 0.03mm 0.05 mm 0.1mm 珠塡充率 5 3.7 % 2 9.3% 2 9.3% 處理量 1 L/m i η 將分散機啓動後，在每個預定的時間，由分散機的排 出口採取樣品。對於粒徑的測定，使用日機裝（股）公司的 粒度分析儀（microtrac®)mkiidra，根據雷射繞射、光 散亂法，進行測量。 -18 - (16) (16)1355290 [實施例3] 使用粒徑0.03mm的氧化锆珠作爲介質，將其對於分 散槽的容積塡充53.7%，將轉子的旋轉數設爲l60〇rpm進 行分散試驗。其結果，在開始運轉90分鐘後，處理物的平 均粒子徑形成24.1 nm，未見混入有介質。 [實施例4] 使用粒徑0.〇5mm的氧化锆珠作爲介質，將其對於分 散槽的容積塡充29.3% ’將轉子的旋轉數設爲2640rpm進 行分散試驗。其結果，在開始運轉90分鐘後，處理物的平 ，均粒子徑形成64.3nm，未見混入有介質。 [實施例5] 使用粒徑0.1〇mm的氧化銷珠作爲介質，將其對於分 散槽的容積塡充29.3% ’將轉子的旋轉數設爲264〇rpni進 行分散試驗。其結果，在開始運轉9〇分鐘後，處理物的平 均粒子徑形成52.4nm，未見混入有介質。 【圖式簡單說明] 圖1是顯示本發明的介質攪拌型濕式分散機的一實施 例的槪略斷面圖。 圖2是沿著圖工的A_A線所觀看的槪略斷面圖。 圖3疋顯示本發明的介質攪拌型濕式分散機的另一實 施例的槪略斷面圖。The rotating shaft 103 has a tubular shape in which the hollow portion 131 is formed at its axial center, and is provided coaxially with the reinforcing chamber 181 and the main chamber 182. One end of the rotating shaft 103 is located in the main chamber 182, and the outer rotor 1 〇 4 and the inner rotor 1 〇 5 are mounted. Further, the other end of the rotary shaft 103 is located outside the dispersion groove X02, and a driving device (not shown) is attached. The outer rotor 1〇4 is constituted by a disk-shaped holding portion 141 and a cylindrical portion 142. The open end of the outer rotor 104 is located in the reinforcing chamber 181, and the other end closed by the holding portion 141 is located in the main chamber 182, and is attached to the rotating shaft 110 by a key 146. -12- (10) (10) 1355290 One end of the tubular portion 142 is located in the vicinity of the end plate 123 of the reinforcing chamber 181. Thereby, the reinforcing chamber 181 having a ring-shaped cross section is divided into two regions inside and outside, and the stirring can be performed efficiently. Further, in the tubular portion 142 of the main chamber 182, as in the case of the first embodiment (Figs. 1 and 2), a plurality of blades 144 are arranged in a cylindrical shape at regular intervals. Therefore, when the outer rotor 104 is rotated in the direction of the arrow of the figure, centrifugal force is generated by the blades 144. Then, the treatment liquid flows through the opening 145 between the blades 144 and flows from the inside toward the outside. As a result, the treatment liquid and the medium 107 in the dispersion tank 1〇2 form a circulation flow. In other words, the outer side of the vane 144 flows toward the one end side from the other end side, and flows from the outer side toward the inner side at the opened end, and flows from the one end side toward the other end side inside the vane 144. Further, by the rotation of the outer rotor 104, the treatment liquid in the dispersion tank 1〇2 is stirred in the same manner as the medium 1〇7. Then, the pulverization and dispersion treatment are carried out by the shearing force generated between the inner wall of the dispersion tank 102 and the vane I44. At the same time, the processing liquid is circulated to the inside and the outside of the outer rotor 104, so that the whole is well stirred, and the entire processing liquid is uniformly processed. By providing the reinforcing chamber 181 in the dispersion tank 102, the performance of the pulverization and dispersion treatment can be dramatically improved. This is because the cross section of the reinforcing chamber 181 is changed so that the inner and outer surfaces of the outer rotor 104 are close to the inner wall of the dispersion groove 102, and the shearing force can be generated. Further, in order to improve the pulverization and dispersion performance, it is preferable that the outer rotor 1〇4 is provided with a plurality of projections 143 on the outer peripheral portion of the tubular portion 142. The portion ' of the attachment projection 143' may be provided on the inner peripheral portion or the outer peripheral portion of the same portion 142 or the inner peripheral portion -13-(11) (11) 1355290 and the outer peripheral portion. Further, it may be opposed to the projection 143 attached to the tubular portion 142, and a projection (not shown) may be provided on the peripheral wall surface of the reinforcing chamber 181 (the outer circumferential surface of the inner cylinder 121 or the inner circumferential surface of the outer cylinder 122). Even when the pulverization of the treatment liquid is increased by the pulverization, the medium 107 can be effectively stirred by providing the projections 143. The inner rotor 105 is located inside the outer rotor 104, and has a cylindrical portion 152 formed of a plurality of blades 154 arranged in a cylindrical shape at a constant interval on one surface of the disk-shaped control device 151. Then, the opened end of the tubular portion 152 is in close contact with the surface of the holding portion 141 of the outer rotor 1〇4, and is fixed to the rotating shaft 103 by bolts 153. The outer peripheral surface of the vane 154 is located slightly apart from the inner peripheral surface of the vane 144 of the outer rotor 1〇4. The gap between the two blades is a flow path formed in the circulation flow inside and outside the outer rotor 104 as described above, and the flow from the one end side of the dispersion groove 102 toward the other end side is formed. Further, the inner circumferential surface of the vane 154 is located slightly apart from the outer surface of the rotary shaft 103, and a space portion 156 is formed inside the vane 154. The rotary shaft 103 is provided with an opening 132 at a position of the space portion 156, and the hollow portion 131 communicates with the space portion 156. As a result, the hollow portion 131 of the rotating shaft 103 forms the discharge port 134 of the dispersion liquid. That is, in the circulation flow, the dispersion liquid subjected to the pulverization and dispersion treatment flows into the space portion 156 through the opening 132 between the blades 154, and is discharged from the discharge port 134. Similarly to the outer rotor 1 〇 4, the inner rotor 205 generates a centrifugal force by the blades 154 when it is rotated in the direction of the arrow shown in the figure. Therefore, the separation function and the classification function are formed for the particles passing through the opening 155. Namely, 8, -14-(12), (12) 1355290, particles or medium 107 having a large particle diameter do not flow into the space portion 156, and only the fine particles are discharged through the space portion 156. Further, the large particles and the medium 107 that have not flowed into the space portion 156 are immediately returned to the circulating flow formed inside and outside the outer rotor 104. Then, since the pulverization and dispersion treatment are performed again, the dispersion treatment and the classification treatment can be surely performed. The inner rotor 105 is located inside the outer rotor 104, and the vanes 154 and the vanes 144 are located at substantially the same position with respect to the axial direction. Thereby, the large particles separated by the inner rotor 105 can be quickly returned to the circulating flow of the outer rotor 1 0 4 . Further, it is preferable that the vane 144 is disposed closer to one end of the dispersing groove 10 2 than the vane 15 4 . This is because the gap between the outer peripheral surface of the vane 154 and the inner peripheral surface of the vane 144 is a flow path of the circulating flow, and the flow from the one end side of the dispersing groove 102 toward the other end side is formed. Therefore, in the case where the vane 144 is closer to one end of the dispersing groove 102 than the vane 154, the vane 144 is located on the upstream side of the circulating flow, and the vane 154 is located on the downstream side of the circulating flow. Therefore, after the upstream blades 144 are separated from the large particles in advance, the downstream blades 154 are finally separated and classified to form an effective treatment. The member that is in direct contact with the treatment liquid such as the dispersion tank 102, the outer rotor 1〇4, and the inner rotor 105 is preferably a material having wear resistance, and a ceramic such as alumina, alumina, chromia, or tantalum carbide is preferably used. Thereby, impurities can be prevented from being mixed into the product. The medium agitation type wet disperser 101 of the present invention is capable of performing a vigorous stirring operation in a narrow -15 - (13) (13) 1355290 dispersion tank 102. Therefore, as shown in the figure, the cooling cover 6 is provided outside the dispersion tank 2, and it is preferable to forcibly cool the dispersion tank 1〇2. The cooling cover 1〇6 covers the entire dispersion tank i02 as much as possible, and the water supply port 161 and the drain port 162 are provided in consideration of the fact that the cooling water does not deflect. Temperature management of the treatment can be performed by the outer cover 106. Further, it may be used as a heating cover immediately after the treatment or the like. [Example 1] Using the medium agitation type wet disperser of the present invention described in the first embodiment, the test for dispersing the secondary agglomerated titanium oxide was carried out under the conditions shown below, and the performance was confirmed. The prepared slurry is placed in a holding tank, and the pump is introduced into the supply port of the dispersing machine by a quantitative pumping, and the slurry discharged from the discharge port of the dispersing machine is returned to the holding tank again to form a circulation system, in which state Start the disperser for testing. After the dispersing machine is started, samples are taken from the discharge port of the dispersing machine at each predetermined time. For the measurement of the particle size, the particle size analyzer (MICR〇TRAC®) MKIIDRA of Nikkiso Co., Ltd. was used to measure according to the laser diffraction 'light scattering method.
