（分離板２０１の詳細な構成と分離作用）
分離板２０１（ディスク）は、図２に示すように、例えば厚さ０．５ｍｍのステンレス鋼からなる笠状、すなわち上端部を開放底面に平行な平面で切除し、内周側に同平面内のリング状部２０１ａが設けられた円錐台形状を有している。上記分離板２０１の外周面には、分離板型遠心分離機に組み付けられたときに各分離板２０１の間隔を例えば０．６ｍｍに保つための間隙部として、分離板の円錐母線に沿った短冊状の間隙片２０２が設けられている。上記リング状部２０１ａの内周側の一部には、切欠部２０１ｂが形成され、図１に示す案内筒１０５に形成されたキー溝１０５ａとの間にキー２５１が挿入されることによって、分離板２０１の回転方向位置の位置決め（同期、回り止め）がなされるようになっている。なお、間隙片２０２は、短冊状に限らず、円形状や小判形などでもよい。さらに、間隙片が設けられるのに限らず、後述する凹凸部２０３等とは異なる凹凸が上下の分離板２０１で重ならないように形成されたりして、各分離板２０１の間隔が所定に保たれるようにされてもよい。また、凹凸が上下の分離板２０１で重なる位置に形成される場合でも、凸部の曲率半径よりも凹部の曲率半径の方が小さいことなどによって各分離板２０１の間隔が所定に保たれるようにされてもよい。 (Detailed configuration and separation action of separation plate 201)
As shown in FIG. 2, the separation plate 201 (disc) has a cap shape made of stainless steel having a thickness of, for example, 0.5 mm, that is, the upper end thereof is cut off in a plane parallel to the open bottom surface, and the separation plate 201 (disk) is in the same plane on the inner peripheral side. It has a truncated cone shape provided with the ring-shaped portion 201a. On the outer peripheral surface of the separation plate 201, a strip along the conical generatrix of the separation plate is provided as a gap for keeping the distance between the separation plates 201 at, for example, 0.6 mm when assembled to the separation plate type centrifuge. The shaped gap piece 202 is provided. A notch 201b is formed in a part of the inner peripheral side of the ring-shaped portion 201a, and the key 251 is inserted between the notch and the key groove 105a formed in the guide cylinder 105 shown in FIG. 1 to separate the ring-shaped portion 201a. The position of the plate 201 in the rotation direction is positioned (synchronized, detented). The gap piece 202 is not limited to a strip shape, but may be a circular shape or an oval shape. Further, not only the gap pieces are provided, but also irregularities different from the uneven portion 203 and the like, which will be described later, are formed so as not to overlap with the upper and lower separating plates 201, so that the distance between the separating plates 201 is kept predetermined. It may be made to be. Further, even when the unevenness is formed at the position where the upper and lower separating plates 201 overlap, the distance between the separating plates 201 is kept predetermined because the radius of curvature of the concave portion is smaller than the radius of curvature of the convex portion. May be made.
分離板２０１（ディスク）は、図２に示すように、例えば厚さ０．５ｍｍのステンレス鋼からなる笠状、すなわち上端部を開放底面に平行な平面で切除し、内周側に同平面内のリング状部２０１ａが設けられた円錐台形状を有している。上記分離板２０１の外周面には、分離板型遠心分離機に組み付けられたときに各分離板２０１の間隔を例えば０．６ｍｍに保つための間隙部として、分離板の円錐母線に沿った短冊状の間隙片２０２が設けられている。上記リング状部２０１ａの内周側の一部には、切欠部２０１ｂが形成され、図１に示す案内筒１０５に形成されたキー溝１０５ａとの間にキー２５１が挿入されることによって、分離板２０１の回転方向位置の位置決め（同期、回り止め）がなされるようになっている。なお、間隙片２０２は、短冊状に限らず、円形状や小判形などでもよい。さらに、間隙片が設けられるのに限らず、後述する凹凸部２０３等とは異なる凹凸が上下の分離板２０１で重ならないように形成されたりして、各分離板２０１の間隔が所定に保たれるようにされてもよい。また、凹凸が上下の分離板２０１で重なる位置に形成される場合でも、凸部の曲率半径よりも凹部の曲率半径の方が小さいことなどによって各分離板２０１の間隔が所定に保たれるようにされてもよい。 (Detailed configuration and separation action of separation plate 201)
As shown in FIG. 2, the separation plate 201 (disc) has a cap shape made of stainless steel having a thickness of, for example, 0.5 mm, that is, the upper end thereof is cut off in a plane parallel to the open bottom surface, and the separation plate 201 (disk) is in the same plane on the inner peripheral side. It has a truncated cone shape provided with the ring-
ここで、上記のような分離板２０１の間に被処理流体を遠心分離によって処理する場合の分離能力（処理量）は、一般に、沈降面積、すなわち分離板２０１の表面積に比例する。そこで、分離能力を大きくするためには、通常、分離板２０１の枚数を多くしたり、外径を大きくしたりされる。これに対して、本実施形態の分離板２０１では、例えば短冊状の間隙片２０２の間の領域に、円弧状の凹凸部２０３が形成されている。すなわち、例えば図３に示すような波形の断面形状が現れる凹凸部２０３が形成されている。この場合、分離板２０１の外形寸法が同じでも、円錐面の表面積が大きくなるので、処理能力を大きくすることが容易にできる。それゆえ、例えば、粒子サイズが微少な場合などに高い処理能力を得ることも、容易にできる。
Here, the separation capacity (processing amount) when the fluid to be treated is treated by centrifugation between the separation plates 201 as described above is generally proportional to the sedimentation area, that is, the surface area of the separation plate 201. Therefore, in order to increase the separation capacity, the number of separation plates 201 is usually increased or the outer diameter is increased. On the other hand, in the separation plate 201 of the present embodiment, for example, an arc-shaped uneven portion 203 is formed in a region between the strip-shaped gap pieces 202. That is, for example, the uneven portion 203 in which the cross-sectional shape of the waveform as shown in FIG. 3 appears is formed. In this case, even if the outer dimensions of the separation plate 201 are the same, the surface area of the conical surface is large, so that the processing capacity can be easily increased. Therefore, for example, it is possible to easily obtain a high processing capacity when the particle size is very small.
（変形例）
分離板２０１の表面積を大きくするためには、図２に示したような円弧状の凹凸部２０３に限らず、例えば図４に示すような円錐形状の母線に沿った線分状の凹凸部２０３や、図５に示すようならせん状などの曲線状の凹凸部２０３が形成されてもよい。また、図６に示すような離散した島状の凹凸部２０４が形成されたりしてもよい。さらに、これらを含む種々の形状の凹凸部が組み合わされたりしてもよい。また、凹部と凸部とが形成されるのに限らず、凹部だけや、凸部だけが形成されたりしてもよい。ここで、分離板２０１における円錐台形状の底部側部分と頂部側部分とで凹凸部２０３等の密度を異ならせたりしてもよい。具体的には、例えば、頂部側部分には凹凸部２０３が設けられていない領域や粗である領域が設けられて、分離板２０１を円板材料から深絞りによって形成する際に頂部付近でしわなどが生じにくいようにしたりしてもよい。逆に、凹凸部２０３等を設けることによって、しわなどが吸収されるようにしてもよい。 (Modification example)
In order to increase the surface area of theseparation plate 201, it is not limited to the arc-shaped uneven portion 203 as shown in FIG. 2, for example, the line segment-shaped uneven portion 203 along the conical generatrix as shown in FIG. Alternatively, as shown in FIG. 5, a curved uneven portion 203 such as a spiral shape may be formed. Further, discrete island-shaped uneven portions 204 as shown in FIG. 6 may be formed. Further, uneven portions having various shapes including these may be combined. Further, the concave portion and the convex portion are not limited to be formed, and only the concave portion or the convex portion may be formed. Here, the density of the uneven portion 203 or the like may be different between the bottom side portion and the top side portion of the truncated cone shape of the separation plate 201. Specifically, for example, a region where the uneven portion 203 is not provided or a rough region is provided on the top side portion, and when the separation plate 201 is formed from the disk material by deep drawing, wrinkles are formed near the top. You may make it difficult for such things to occur. On the contrary, wrinkles and the like may be absorbed by providing the uneven portion 203 and the like.
分離板２０１の表面積を大きくするためには、図２に示したような円弧状の凹凸部２０３に限らず、例えば図４に示すような円錐形状の母線に沿った線分状の凹凸部２０３や、図５に示すようならせん状などの曲線状の凹凸部２０３が形成されてもよい。また、図６に示すような離散した島状の凹凸部２０４が形成されたりしてもよい。さらに、これらを含む種々の形状の凹凸部が組み合わされたりしてもよい。また、凹部と凸部とが形成されるのに限らず、凹部だけや、凸部だけが形成されたりしてもよい。ここで、分離板２０１における円錐台形状の底部側部分と頂部側部分とで凹凸部２０３等の密度を異ならせたりしてもよい。具体的には、例えば、頂部側部分には凹凸部２０３が設けられていない領域や粗である領域が設けられて、分離板２０１を円板材料から深絞りによって形成する際に頂部付近でしわなどが生じにくいようにしたりしてもよい。逆に、凹凸部２０３等を設けることによって、しわなどが吸収されるようにしてもよい。 (Modification example)
