中（被處理液中）所混入固態雜質的清淨機使用（專利文獻1)<} [專利文獻1]日本專利特開2002-336734號公報 【發明内容】 (發明所欲解決之問題） 此種分離板型離心分離機的構造’係具備有由在旋轉體内 的旋轉軸方向’將薄金屬板利用沖壓加工成形為戴頭圓錐带 狀的分離板，多數積層且可分解僅以單純組合所構成之分離 板組，在分離板組的各層中，形成相對位於上下位置的各八 離板間之相互上下間隙(即’各層的上分離板之圓錐面内面 (下面）、與下分離板的圓錐面外面（上面）間）的圓錐面間隙， 係利用在下分離板的圓錐面外面（上面）之圓錐母線方向複 數配設的隔離空間隔間突條部，於旋轉體的旋轉方向上相5 間隔，且例如分開成8份而形成8室的隔離空間，並將其^ 099112296 3 201102170 作利用離心分離進行的液中固體沉降作用面。 利用此種構造的分離機所施行的分離處理，係依如下述實 施。 例如若屬於燃料油、潤滑油等被處理液（以下，亦稱「原 液」）’被從旋轉體的旋轉軸方向導入旋轉體内’便利用離 心力，從上述分離板組的下方側經由上下方向貫穿分離板組 的流通孔，流入於各隔離空間並持續擴散。 經賦予離心力的被處理液係在經由縱向貫穿分離板組的 流通孔，再流入各隔離空間中，並在該等各隔離空間内進行 擴散的同時，液體會以朝向分離板中心（即旋轉軸方向）依攀 登圓錐面傾斜的方式，在上下分離板的圓錐面間進行流動。 另一方面，在被處理液中所混入的多樣固態雜質粒子’將 利用離心沉降，而沉降至用以形成該隔離空間的上分離板之 圓錐面内面（下面）側，並沿所沉降的圓錐面朝隔離空間外周 緣侧（即，圓錐面底邊側）進行流動（從隔離空間中的排出流 動）。 當已沉降的固態雜質粒子依此朝向隔離空間外周緣進行 排出流動時，便利用依形成該隔離空間（隔間）的方式’在旋 轉方向前後所配置的2個隔離空間隔間突條部中，位於後方 的隔離空間隔間突條部，詳言之，係利用該隔離空間隔間突 條部旋轉方向側緣(前緣）的旋轉正面緣’一邊導引著固態雜 質粒子，一邊依宛如利用隔離空間隔間突條部從隔離空間中 099112296 4 201102170 掃出的方式，被朝隔離空間外周緣側的上分離板之内面側底 邊（即該分離板外周端）移送。 依此的話，從各隔離空間送出其外周緣的固態雜質，將集 中並累積於其外周緣，且到達分離組周圍的旋轉體内之空間 中，最終，暫時儲存於該旋轉體内最外周空部之所謂固態雜 質集塵場所的旋轉體内最大徑部處，再利用適當手段適當地 排放出旋轉體外。 依如上述，分離板組的上下分離板間之各隔離空間，便具 有使液中雜質的固體利用離心力沉降的分離沉降面之功 能，而形成隔離空間的隔離空間隔間突條部（之前緣），則具 有已沉降於各隔離空間（即，分離沉降面）的固態雜質，從該 隔離空間（分離沉降面）中掃出並排除的功能。 但是，習知隔離空間隔間突條部係以直線方式，配設在與 截頭圓錐形狀分離板的圓錐母線呈一致的方向，因為相對於 分離板組(及其分離板）的旋轉方向呈正向的正交配設，因而 對旋轉體中或隔離空間中的被處理液，雖以該被處理液當作 旋轉方向而賦予旋轉力（即，離心力）是有效的，但另一方面 亦相對會承受到較大阻力。以下，本說明書中將該阻力稱「被 處理液阻力」。 該被處理液阻力的大小，當然不僅依照被處理液的性狀 (例如，黏性等）而有所差異，即便因旋轉體的旋轉速度變化 亦會產生變化，並非經常呈一定。 099112296 5 201102170 因而，若對由薄板形成的分離板，或由此種分離板的多數 組合’依較單純積層構造的分離板組，作用無用的力，該等 便會產生無用的變形、或因變形產生振動，導致會有對分離 板或分離板組在設計上所被賦予的作用效果，無法直接充分 發揮的情況發生。 又’因此種無用的變形與振動，在分離板的材質（金屬）中 會滯留預算外的疲勞，或者分離板遭破損、或因該破損而導 致分離板組或旋轉體遭受損傷，亦會有引發分離機自體出現 故障或意外的虞慮。 本發明係為解決上述問題而完成，目的在於提供一種相較

針對實施例的分離板型離心分離機構造，就圖1至圖6 進行說明。 圖1係分離板型離心分離機的旋轉體剖視圖，圖2係構成 分離板組的分離板平面圖，圖3係分離板的仰視圖，圖4 係分離板的側視圖，圖5係分離板的立體圖，圖6係分離板 的縱剖視圖。 圖1中，在旋轉體1的内部，設有在旋轉體1的旋轉軸方 向多數積層著傘狀分離板2的分離板組20。構成該分離板 組20的分離板2係如圖2至圖6所示，藉由對薄金屬平板 施行沖壓加工而加工呈截頭圓錐形狀。 圖1中，在分離板組20的各層中，在積層方向位於上下 相對位置的上方之各分離板2與下方之分離板2間之相互上 下間隙，即，圖2至圖6所示之分離板2中，於各層的上分 離板2之圓錐面21的内面（下面）212、與下分離板2的圓錐 面21之外面（上面）211間，形成作為導入被處理液（圖1的 分離板組20中，朝圖示斜上方的多數箭頭係指被處理液的 導入方向）的間隙用之圓錐面間隙（未圖示）。 在相對性位於下方的分離板2之圓錐面21外面（上面）211 上，在該圓錐面21的略圓錐母線方向上，朝旋轉體1的旋 轉方向（本貫施例中，圖中的右方向=逆時針）相隔間隔設置 099112296 10 201102170 隔離空間隔間突條部3,並依例如分開成8份而形成8室隔 離空間4的方式，在圖2的平面圖上從旋轉中心側呈輕射狀 配設複數個。 利用實施例的分離機所施行的被處理液(含有污泥或水分 的燃料油與潤滑油等）之分離處理，大致上係利用一次分離 與二次分離依如下述施行離心分離處理。 首先’圖1中，被處理液係從在旋轉體1的旋轉軸設置於 旋轉方向的導入口 η，導入於旋轉體1内，利用由旋轉體1 的南速旋轉所產生離心力’分離為比重較輕的輕液、比重較 重的重液、及固態物等（以下’將其稱「一次分離處理」）。 矛J用邊一次分離處理所分離的比重較輕之輕液，係從分離 板組20的下方側朝向上方側，上下方向貫通該分離板組 20 ’至少以貫通各隔離空間4中每一該隔離空間4的方式， 朝上方流至設置於圓錐面下邊側所設置的各流通孔22，再 依序從下方流入於上方的各層各隔離空間4,且在各隔離空 間4内擴散。 接著，針對二次處理進行簡單說明。 首先，在圖1中，於各隔離空間4内擴散的被處理液，因 為被賦予離心力，因而在從該等各隔離空間4的流通孔22 机入於各隔離空間4並擴散的同時，被處理液的液體在上下 分離板2、2的圓錐面21間，即，屬於上分離板2的圓錐面 21内面（下面）212、與下分離板2的圓錐面21外面（上面）2ΐι 099112296 201102170 之間隙的隔離空間4内，朝分離板2的中心（即，旋轉軸方 向），依攀登下圓錐面21的傾斜面211方式，朝上方流動。 該流動（即向上流通)係如在圖丨分離板組2〇中，依朝斜 上方且朝旋轉轴方向之方式所標示的多數箭頭。 依此，經由分離板組20的各層分離板2之隔離空間4的 間隙，朝分離板組20的上層側（即向上）流通的較輕之被處 理液，最終，便攸圖1所示之在旋轉體1的旋轉轴附近所設 置回收口 15，回收而成為淨化液。 另一方面，請再度參照圖1，經混入被處理液中的處理對 象之各個多樣固態雜質粒子中，比重較大的粒子會利用由旋 轉體1的南速旋轉所產生之離心沉降，迅速地到達並集聚於 旋轉體1内的空間12之最大徑部13’再從在旋轉體丨的本 體周圍且設置於最大徑部13的排出口 μ，利用適當時序與 適當手段被排放出旋轉體4外。該最大徑部13若從旋轉體 4的内部側觀看，係内部的最外周空部，且屬於暫時性儲存 固態雜質的集塵•集聚場所。 又，比重較重的被處理液、與被處理液中所含的固態雜質 粒子等，將在利用分離板組20所形成且構成寬廣沉降面（分 離板2的圓錐面積X分離板2之數量）的各隔離空間4中，如 圖2至4所示，沉降於該隔離空間4之沉降面，即，沉降至 用以形成隔離空間4而相對位於上方（頂板側）的上分離板2 之圓錐面21内面（下面）m侧（利用離心力沉降於該隔離空 099112296 12 201102170 間4的頂板側）(參照圖4、5)，並沿所沉降的圓錐面21，朝 該隔離空間4的外周緣41側（即，該圓錐面21的底邊41側） •流動。以下，將該流動稱為從隔離空間4的排出流動。 在各隔離空間4内沉降的各多樣質量的固態雜質粒子，當 朝各隔離空間4的外周緣41被排出流動時，便利用在旋轉 方向複數形成該隔離空間4的方式(相隔隔間）、且在旋轉方 向的前後方向相隔間隔配置，相對性構成一對的2個隔離空 間隔間突條部3、3中，位於旋轉方向後方的隔離空間隔間 . 犬條部3(例如’圖4中相對於元件符號3F所示之隔離空間 隔間突條部，便為隔離空間隔間突條部3R)，正確地說，係 利用屬於該隔離空間隔間突條部於旋轉方向側緣（前緣) 的旋轉正面緣3卜—邊將固態雜質粒子依例如圖4與圖5 中虛線前頭的流動執跡進行導引，一邊宛如利用隔離空間隔 間突條部3R從該隔離空間4中掃出的方式，被朝該隔離空 間4的外周緣41側之上分離板2的内面212側底邊41(該 分離板2的外周緣41)側送出。 圖1中，如上述，被從各隔離空間4朝其外周緣41側送 . 出，且排放出分離板組20外的固態雜質（未圖示），到達分 • 離板組20周圍的旋轉體1内之空間12,最後，便如同上述， 暫時儲存於該旋轉體4内的最外周空部之所謂固態雜質集 塵場所的_體4内之最大徑部13中’並利用適當手段從 排出口 14中排出於旋轉體4外。 099112296 13 201102170 圖2至圖5中，在分離板2的圓錐面21之上面211，配 設於該圓錐面21的圓錐母線方向之隔離空間隔間突條部 3，係依相較於通過該隔離空間隔間突條部3的圓錐面上邊 43側之端3A的圓錐母線，通過該隔離空間隔間突條部3 的圓錐面21之底邊41側的端3B之圓錐母線朝位於旋轉體 1的旋轉方向位置偏移的方式，相對於圓錐母線呈交叉斜向 傾斜，並利用在旋轉方向位於前後的2個隔離空間隔間突條 部3、3所隔間的隔離空間4内，該隔離空間4内比重較輕 之被處理液，被一邊導引（誘導)於該隔離空間隔間突條部3 的旋轉正面緣31(即，該隔離空間隔間突條部3的前緣31)， 一邊朝該圓錐面21的上邊43側方向進行流動移動的方式配 設。 隔離空間隔間突條部3於旋轉體1之旋轉方向側的旋轉正 面緣，係可形成直線性，圖示例中，整體形成帶狀的隔離空 間隔間突條部31，係設計彎曲形成朝旋轉體31旋轉方向（圖 中的右方向）膨出之緩和曲線的彎曲部。依此，彎曲部係可 跨越隔離空間隔間突條部3的旋轉正面緣31全長形成，亦 可在隔離空間隔間突條部3的旋轉正面緣31，形成於靠近 圓錐面21的底邊41側。 根據本實施例，因為如上述，隔離空間隔間突條部3係相 對於分離板2的圓錐母線呈斜向傾斜配設，因而在各隔離空 間中，至少比重較輕的被處理液之流動方向，會利用相對於 099112296 14 201102170 圓錐母線呈斜向傾斜配設的隔離空間隔間突條部3，被誘導 成朝該隔離空間的上部側順暢流動並集聚，因而藉由被誘導 並集聚的被處理液較一定的流量所產生之壓力與重量，將產 生例如分離板2在其圓錐面21中依較岣等朝下方（旋轉軸方 向的下方)按押的抑制作用，便使分離板2處於安定的紐裝 狀態，可使分離板2與分離板組20在不致產生無用的搖晃 情況下’順暢地進行旋轉’因而可發揮較高的離心分離功能。 再者’實施例中，在形成截頭圓錐形狀的圓錐面21上， 將形成「〜」字狀的隔離空間隔間突條部3利用點炼接呈一 體裝設，而設置分離板3，可與分離板3本體的圓錐面板21 輕易地形成不易分離的牢固構造。 實施例所示「〜」字狀隔離空間隔間突條部3的形狀，係 在以船舶用柴油引擎的燃料油、潤滑油等當作被處理液的固 液分離性能實驗中，經重覆實施實驗而在實驗上發現的較佳 形狀，當然並不僅侷限於此形狀。

Description of the Invention: [Technical Field] The present invention relates to a separation plate for separating a liquid to be treated (liquid) from a liquid liquid and/or a solid liquid by using high rotation/high centrifugal force. Type centrifugal separator and its separator plate. [Prior Art] The knife-off-plate type centrifugal separator (hereinafter also referred to as "separator") is used in most industrial fields, for example, fuel oil for marine diesel engines. Purification with Run/Men oil, or as a purifier for removing solid impurities mixed in the oil used as the liquid to be treated (in the liquid to be treated) (Patent Document 1) <} [Patent Literature (1) The structure of the separation plate type centrifugal separator is configured to have a thin metal by the direction of the rotating shaft in the rotating body. The plate is formed into a split-cone-shaped separating plate by press working, and a plurality of separating plates which are laminated and can be decomposed only by a simple combination, and each of the separating plates is formed in each of the layers of the separating plate group. The conical surface gap between the upper and lower gaps (ie, the inner surface of the conical surface of the upper separation plate (below) and the outer surface of the conical surface of the lower separation plate (the upper surface)) is used outside the conical surface of the lower separation plate (above The isolated inter-spaced ridges of the plurality of conical busbars are spaced apart by 5 in the direction of rotation of the rotating body, and are separated into, for example, 8 parts to form an 8-chamber isolation space, and the ^099112296 3 201102170 The sedimentation surface of the solid in the liquid by centrifugation. The separation treatment performed by the separator having such a configuration is carried out as follows. For example, if the liquid to be treated such as fuel oil or lubricating oil (hereinafter also referred to as "raw liquid") is introduced into the rotating body from the direction of the rotation axis of the rotating body, it is convenient to use centrifugal force, and the lower side of the separating plate group is vertically moved. The flow holes penetrating the separation plate group flow into the respective isolation spaces and continue to diffuse. The liquid to be treated which is subjected to the centrifugal force is passed through the flow holes penetrating the separation plate group in the longitudinal direction, flows into the respective isolation spaces, and diffuses in the respective isolation spaces, and the liquid is directed toward the center of the separation plate (ie, the rotation axis) Direction) Flows between the conical faces of the upper and lower separating plates in a manner that the climbing conical surface is inclined. On the other hand, the various solid impurity particles 'mixed in the liquid to be treated' will be settled by centrifugation, and settled to the inner surface (lower side) of the conical surface of the upper separation plate for forming the separation space, and along the conical cone The flow is made toward the outer peripheral side of the isolated space (i.e., the bottom side of the conical surface) (discharge flow from the isolated space). When the settled solid impurity particles are discharged toward the outer periphery of the isolation space, it is convenient to use the isolation space (compartment) in the manner of 'separating the two spaced apart space protrusions arranged before and after the rotation direction. , in the rear of the isolation space between the ridges, in particular, by using the rotating front edge of the side edge (leading edge) of the direction of rotation of the slats in the space between the gaps, while guiding the solid foreign particles, By means of the detachment of the detachment space between the detachment spaces 099112296 4 201102170, the inner side of the upper separation plate on the outer peripheral side of the isolation space (that is, the outer peripheral end of the separation plate) is transferred. In this case, the solid impurities that are sent out from the respective isolation spaces are concentrated and accumulated on the outer periphery thereof, and reach the space in the rotating body around the separation group, and finally, temporarily stored in the outermost space of the rotating body. At the largest diameter portion of the rotating body of the so-called solid-state impurity dust collecting place, it is appropriately discharged to the outside of the rotating body by an appropriate means. According to the above, each of the isolation spaces between the upper and lower separation plates of the separation plate group has the function of separating the sedimentation surface for solidification of the solid impurities in the liquid by centrifugal force, and forms the isolation space between the isolation space (front edge) Then, there is a function of solid impurities which have settled in the respective isolation spaces (i.e., separated sedimentation surfaces), which are swept out and excluded from the separation space (separation sedimentation surface). However, the conventional isolation space between the ridges is arranged in a straight line in a direction consistent with the conical busbar of the frustoconical separating plate because it is positive with respect to the direction of rotation of the separating plate group (and its separating plate). The orthogonal arrangement of the directions is effective for imparting a rotational force (i.e., centrifugal force) to the liquid to be treated in the rotating body or in the isolated space as the direction of rotation of the liquid to be treated, but on the other hand, Withstand greater resistance. Hereinafter, in the present specification, the resistance is referred to as "resistance of treated liquid". The magnitude of the resistance of the liquid to be treated is of course different depending not only on the properties of the liquid to be treated (e.g., viscosity, etc.), but also varies depending on the rotational speed of the rotating body, and is not always constant. 099112296 5 201102170 Thus, if a separating plate formed of a thin plate, or a combination of a plurality of such separating plates, a separate plate group of a simple laminated structure, exerts a useless force, which may cause useless deformation or cause The deformation generates vibration, which results in a design effect on the separation plate or the separation plate group, which cannot be directly exerted. In addition, the useless deformation and vibration will cause extra-budget fatigue in the material (metal) of the separation plate, or the separation plate may be damaged, or the separation plate group or the rotating body may be damaged due to the damage. Causes the separator to malfunction or unexpectedly. The present invention has been made to solve the above problems, and an object thereof is to provide a separating plate which is capable of reducing the resistance of a liquid to be treated and which does not impart useless treatment liquid resistance to the separation plate and the separation plate group, and provides Separating plate type centrifugal separator having the separating plate" (Means for solving the problem) The first invention of the present invention is a truncated cone which is laminated in the rotating shaft direction of the rotating body in the rotating body of the separating plate type centrifugal separator a shape separating plate; wherein a conical surface gap between the upper and lower separating plates of the stacked layer is formed in an isolated space at intervals in a rotation direction of the rotating body, and a conical surface of the separating plate located below The slanting busbar is disposed in the direction of the conical busbar, and is opposite to the conical section of the conical surface of the conical surface of the sulking portion of the sulking space, and the bottom surface of the conical surface passing through the ridge portion of the isolation space The side & conical busbars are located offset from the direction of the rotation of the rotating body by 099112296 6 201102170 and are arranged diagonally with respect to the conical busbar. The invention relates to a separating plate for a separating plate type centrifugal separator according to the second aspect of the present invention, which is characterized in that the rotating front edge of the slanting portion of the space between the slats and the rotating body is bulging from the rotating direction of the rotating body The curved way forms a curved bend.

A perspective view, Fig. 6 is a longitudinal sectional view of the separating plate. In Fig. 1, a separating plate group 20 in which an umbrella-shaped separating plate 2 is stacked in the direction of the rotation axis of the rotating body 1 is provided inside the rotating body 1. The separating plate 2 constituting the separating plate group 20 is processed into a frustoconical shape by press working a thin metal plate as shown in Figs. 2 to 6 . In Fig. 1, in each layer of the separation plate group 20, the upper and lower gaps between the separation plates 2 and the lower separation plates 2 above the upper and lower relative positions in the lamination direction, that is, the separation shown in Figs. 2 to 6 In the plate 2, between the inner surface (lower surface) 212 of the conical surface 21 of the upper separation plate 2 of each layer and the outer surface (upper surface) 211 of the conical surface 21 of the lower separation plate 2, the liquid to be treated is introduced as the introduction liquid (the separation of Fig. 1) In the plate group 20, a plurality of arrows which are obliquely upward in the figure indicate a conical surface gap (not shown) for a gap in the direction in which the liquid to be treated is introduced. On the outer surface (upper surface) 211 of the conical surface 21 of the separating plate 2, which is located below, in the direction of the slightly conical generatrix of the conical surface 21, in the direction of rotation of the rotating body 1 (in the present embodiment, the right side in the figure) Direction = counterclockwise) interval setting 099112296 10 201102170 Isolating the space between the rib portions 3 and forming the 8-chamber isolation space 4 by, for example, dividing into 8 parts, and illuminating from the center of rotation on the plan view of Fig. 2 A plurality of shapes are arranged. The separation treatment of the liquid to be treated (fuel oil containing sludge or moisture, lubricating oil, etc.) by the separator of the embodiment is roughly performed by one-time separation and secondary separation as follows. First, in Fig. 1, the liquid to be treated is introduced into the rotating body 1 from the inlet η provided in the rotating direction of the rotating shaft of the rotating body 1, and is separated into the specific gravity by the centrifugal force generated by the south-speed rotation of the rotating body 1. Lighter light liquid, heavy liquid heavy liquid, and solid matter (hereinafter referred to as "one-time separation treatment"). The spear J is separated from the lower portion of the separation plate group 20 toward the upper side by the separation process, and penetrates the separation plate group 20' in the up-and-down direction at least through each of the isolation spaces 4 In the manner of isolating the space 4, the flow holes 22 provided on the lower side of the conical surface are flowed upward, and then flowed downward from the lower layers of the respective isolation spaces 4, and diffused in the respective isolation spaces 4. Next, a brief description will be given for the secondary processing. First, in FIG. 1, the liquid to be treated which is diffused in each of the isolation spaces 4 is centrifugally applied, and is introduced into the respective isolation spaces 4 from the flow holes 22 of the respective isolation spaces 4, and is diffused. The liquid of the treatment liquid is between the conical surfaces 21 of the upper and lower separation plates 2, 2, that is, the inner surface (lower surface) 212 of the conical surface 21 belonging to the upper separation plate 2, and the outer surface (upper surface) of the conical surface 21 of the lower separation plate 2 2 ΐ 099112296 201102170 In the space 4 of the gap, the center of the separation plate 2 (that is, the direction of the rotation axis) flows upward as the inclined surface 211 of the conical surface 21 is climbed. This flow (i.e., upward flow) is a plurality of arrows indicated in the figure 丨 separation plate group 2, in a direction obliquely upward and in the direction of the rotation axis. Accordingly, the lighter treatment liquid flowing toward the upper layer side (ie, upward) of the separation plate group 20 via the gap of the separation space 4 of each layer separation plate 2 of the separation plate group 20 is finally shown in FIG. The recovery port 15 is provided in the vicinity of the rotating shaft of the rotating body 1, and is collected as a cleaning liquid. On the other hand, referring again to FIG. 1, among the various solid impurity particles to be processed in the liquid to be treated, the particles having a large specific gravity are rapidly separated by centrifugal sedimentation caused by the south-speed rotation of the rotating body 1. The maximum diameter portion 13' of the space 12 that has arrived and accumulated in the rotating body 1 is discharged from the discharge port μ around the body of the rotating body and disposed at the maximum diameter portion 13, and is discharged from the rotating body 4 by appropriate timing and appropriate means. outer. The maximum diameter portion 13 is the outermost peripheral portion of the inner portion of the rotating body 4 as viewed from the inner side of the rotating body 4, and is a dust collecting/concentrating place for temporarily storing solid impurities. Further, the liquid to be treated having a relatively large specific gravity and the solid foreign particles contained in the liquid to be treated are formed by the separation plate group 20 and constitute a wide sedimentation surface (the area of the conical area X of the separation plate 2) In each of the isolated spaces 4, as shown in FIGS. 2 to 4, the settling surface settled in the isolated space 4, that is, settled to the upper separating plate 2 for forming the isolated space 4 and relatively located above (the top plate side). The inner side (lower side) m side of the conical surface 21 (sedimented by centrifugal force on the top side of the partition space 099112296 12 201102170 4) (refer to Figs. 4, 5), and along the settled conical surface 21, toward the outer circumference of the isolated space 4 The side of the rim 41 (i.e., the side of the bottom side 41 of the conical surface 21) • flows. Hereinafter, this flow is referred to as a discharge flow from the isolation space 4. When the solid-state impurity particles of various masses settled in the respective isolation spaces 4 are discharged toward the outer peripheral edge 41 of each of the isolation spaces 4, it is convenient to form the isolation spaces 4 in a plurality of directions in the rotation direction (separate compartments), Further, the front and rear directions of the rotation direction are arranged at intervals, and the relative arrangement of the pair of two spaced apart space ribs 3 and 3 is located between the separation spaces behind the rotation direction. The dog portion 3 (for example, 'Fig. 4 In the middle of the isolation gap between the ribs and the ribs 3R), it is said that the ridges 3R) are separated from each other in the rotation direction. The rotating front edge 3 of the leading edge) guides the solid impurity particles according to, for example, the flow front of the dotted line in Figs. 4 and 5, and the side is like the isolation space 4 from the isolation space 4 The sweeping manner is sent toward the inner surface 212 side bottom side 41 (the outer peripheral edge 41 of the separating plate 2) of the separating plate 2 on the outer peripheral edge 41 side of the partition space 4. In Fig. 1, as described above, it is sent out from the respective isolation spaces 4 toward the outer peripheral edge 41 side, and solid impurities (not shown) outside the separation plate group 20 are discharged to reach the rotation around the sub-plate group 20. The space 12 in the body 1 is finally stored in the maximum diameter portion 13 in the body 4 of the so-called solid impurity dust collecting place in the outermost peripheral portion of the rotating body 4 as described above and is appropriately The discharge port 14 is discharged outside the rotating body 4. 099112296 13 201102170 In Fig. 2 to Fig. 5, the upper surface 211 of the conical surface 21 of the separating plate 2 is disposed in the direction of the conical surface of the conical surface 21, and is separated from the rib portion 3 by the passage. The conical bus bar that isolates the end 3A of the conical surface side 43 side of the inter-spaced rib portion 3 passes through the conical bus bar of the end 3B on the side of the bottom side 41 of the conical surface 21 of the intervening space intervening portion 3 toward the rotating body The manner in which the rotational direction of the 1 is offset is inclined obliquely with respect to the conical bus bar, and is utilized in the space 4 in which the intervening rib portions 3 and 3 are located in the front and rear directions in the rotation direction. The liquid to be treated having a relatively small specific gravity in the isolation space 4 is guided (induced) to the rotating front edge 31 of the ridge portion 3 of the separation space (that is, the leading edge 31 of the ridge portion 3 of the isolation space interval 3) It is disposed so as to flow in the direction of the upper side 43 of the conical surface 21. The rotating front edge of the detachment space rib portion 3 on the side of the rotation direction of the rotator 1 is linear, and in the illustrated example, a strip-shaped vacant space rib portion 31 is integrally formed, and is designed to be curved. A curved portion of the relaxation curve that bulges toward the direction of rotation of the rotating body 31 (the right direction in the drawing). Accordingly, the curved portion may be formed across the entire length of the rotating front edge 31 of the isolation gap portion 3, or may be formed at the bottom edge of the conical surface 21 at the rotating front edge 31 of the isolation gap portion 3. 41 side. According to the present embodiment, since the isolation gap portion 3 is obliquely inclined with respect to the conical bus bar of the separation plate 2 as described above, at least the flow of the liquid to be treated having a relatively small specific gravity is generated in each of the isolation spaces. The direction is to use the isolation gap between the 099112296 14 201102170 conical busbars, and is induced to flow smoothly and collect toward the upper side of the isolation space, thereby being induced and concentrated. The pressure and weight generated by the flow rate of the treated liquid at a certain flow rate will cause, for example, the suppression of the separation plate 2 in the conical surface 21 thereof, which is pressed downward (downward in the direction of the rotation axis), so that the separation plate 2 is caused. In the stable state of the new installation, the separation plate 2 and the separation plate group 20 can be 'smoothly rotated' without causing useless shaking, thereby exerting a high centrifugal separation function. Further, in the embodiment, on the conical surface 21 forming the frustoconical shape, the partition space 3 formed in a "~" shape is integrally provided by the spot welding, and the separation plate 3 is provided. The conical panel 21 of the body of the separation plate 3 can be easily formed into a firm structure that is not easily separated. The shape of the "~"-shaped space-spaced ridge portion 3 shown in the embodiment is repeated in the experiment of solid-liquid separation performance of fuel oil, lubricating oil, or the like as a liquid to be treated for a marine diesel engine. The preferred shape experimentally found in the experiment is of course not limited to this shape. (Industrial Applicability) In the above-described embodiment, the separator-type centrifugal separator in which the fuel oil, the lubricating oil, or the like of the marine diesel engine is used as the liquid to be treated is described, but the present invention is not limited thereto. It is also possible to utilize solid-liquid separators used in a wide range of industries.
