開閉自在シャッター（５０３）開放後の動作については、実施例１の遠心分離装置と同様であるので省略する。 Since the operation after opening the openable / closable shutter (503) is the same as that of the centrifugal separator of the first embodiment, a description thereof will be omitted.
実施例３の遠心分離装置は、実施例１の遠心分離装置をベースに分離動作の改善を図り分離性能を向上させた遠心分離装置である。その構成について、図１３に従い実施例１との変更点のみ説明する。 The centrifuge of the third embodiment is a centrifuge that improves the separation performance by improving the separation operation based on the centrifuge of the first embodiment. Only the differences from the first embodiment will be described with reference to FIG.
遠心分離装置（１）は、ケーシング内に設置する回転分離容器（１０）と、当該回転分離容器を支持する回転分離容器支持体（２０）と、前記回転分離容器支持体を回転駆動することにより、当該回転分離容器（１０）を回転させる駆動源である回転分離容器駆動機構（図示せず）と、当該回転分離容器（１０）の軸心を貫通し設置する汚濁原液導入管（４０）と、前記汚濁原液導入管（４０）の直下に位置する円形状の振切り板天面部（４２１）、前記振切り板天面部（４２１）の円周側面から下部方向に垂下形成する円筒状の振切り板側面部（４２２）、及び前記振切り板側面部（４２２）の外側面上を一定間隔で上下方向に棒状突出する複数の汚濁液同期フィン部（４２３）で構成する汚濁液拡散同期ユニット（４２）と、前記振切り板天面部（４２１）へのスラッジ混入を防止するためのスラッジガード（４３）と、当該回転分離容器（１０）の内側面に付着堆積した固体を掻きとり当該回転分離容器（１０）の外部へと排出する固体排出機構（５０）と、比重の軽い軽液を当該回転分離容器（１０）の内部から外部へと導く軽液排出流路（６０）と、比重の重い重液を当該回転分離容器（１０）の内部から外部へと導く重液排出流路（７０）と、で構成する。 The centrifugal separator (1) includes a rotary separation container (10) installed in a casing, a rotary separation container support (20) that supports the rotary separation container, and a rotational drive of the rotary separation container support. A rotary separation container drive mechanism (not shown) which is a drive source for rotating the rotary separation container (10), and a contaminated concentrate introduction pipe (40) installed through the axis of the rotary separation container (10). A circular shaking plate top surface portion (421) located immediately below the dirty stock solution introduction pipe (40), and a cylindrical vibration hanging downward from the circumferential side surface of the shaking plate top surface portion (421). A pollutant diffusion synchronization unit comprising a cut plate side surface portion (422) and a plurality of pollutant synchronization fin portions (423) projecting vertically on the outside surface of the cut plate side surface portion (422) at regular intervals. (42) and the swing-off A sludge guard (43) for preventing sludge from entering the top surface portion (421), and the solid deposited on the inner surface of the rotary separation container (10) are scraped off to the outside of the rotary separation container (10). A solid discharge mechanism (50) for discharging, a light liquid discharge passage (60) for guiding a light liquid with a low specific gravity from the inside of the rotary separation container (10) to the outside, and a heavy liquid with a high specific gravity in the rotary separation container (10) and a heavy liquid discharge channel (70) leading from the inside to the outside.
前記振切り板天面部（４２１）の直径は、滞留液面位置に達する長さに設定している。回転分離容器（１０）の外部から内部に導入直後の汚濁原液を滞留液面位置まで直接誘導するためである。この構成にすることにより、汚濁原液が分離不十分の状態で軽液排出路（６０）に排出されることを防止し得る。 The diameter of the top surface portion (421) of the shaking plate is set to a length that reaches the staying liquid surface position. This is because the contaminated stock solution immediately after being introduced from the outside to the inside of the rotary separation vessel (10) is directly guided to the staying liquid surface position. With this configuration, it is possible to prevent the undiluted stock solution from being discharged into the light liquid discharge path (60) in a state where separation is insufficient.
なお、前記汚濁液同期フィン部（４２３）の形状は、汚濁液を前記回転分離容器（１０）の回転に効率よく同期出来れば良く、公知の様々な形状を採用し得る。この構成を採用することにより、汚濁液の分離効率が向上する。 In addition, the shape of the said pollutant synchronizing fin part (423) should just synchronize a pollutant with rotation of the said rotation separation container (10) efficiently, and can employ | adopt various well-known shapes. By adopting this configuration, the separation efficiency of the contaminated liquid is improved.
なお、前記スラッジガード（４３）の形状は、前記振切り板天面部（４２１）へのスラッジ混入を防止出来れば良く、公知の様々な形状を採用し得る。 The shape of the sludge guard (43) may be any known shape as long as it can prevent sludge from entering the top surface portion (421) of the swing plate.
次に、遠心分離装置（１）の遠心分離中の動作について、比重１未満の油成分と水成分（油成分１：水成分９の場合）とに固体成分（比重１よりも重い）も含まれる汚濁原液を導入した場合を例に取り、図１３に従い実施例１との変更点のみ説明する。 Next, regarding the operation during centrifugation of the centrifugal separator (1), the oil component having a specific gravity of less than 1 and the water component (in the case of oil component 1: water component 9) also include a solid component (heavier than the specific gravity of 1). Taking the case of introducing a contaminated stock solution as an example, only the differences from Example 1 will be described with reference to FIG.
２０００ｒｐｍ〜３０００ｒｐｍ程度で回転する回転分離容器（１０）の外部から内部へ、汚濁原液導入管（４０）を介し汚濁原液を導入すると、当該汚濁原液は汚濁液拡散同期ユニットの振切り板天面部（４２１）の中央部付近に放出され前記振切り板天面部（４２１）の表面に沿って中央部付近から外周部へと放射状に拡散（飛散）し、そのまま滞留液面内へと導出され、直ちに遠心力の影響を受ける。 When the contaminated undiluted solution is introduced from the outside to the inside of the rotary separation container (10) rotating at about 2000 rpm to 3000 rpm through the contaminated undiluted solution introduction pipe (40), the contaminated undiluted solution is converted to the top surface of the shaking plate of the contaminated solution diffusion synchronization unit ( 421) and is diffused (scattered) radially from the vicinity of the central portion to the outer peripheral portion along the surface of the top surface portion (421) of the shaking plate and is led out into the staying liquid surface as it is. Influenced by centrifugal force.
前記滞留液面内へ導出した汚濁液は、遠心力及び前記汚濁液拡散同期ユニットの汚濁液同期フィン部（４２３）の動作により、水成分は前記回転分離容器（１０）の内側面側に分離沈降し、比重１未満の油成分は分離沈降した前記水成分の上面側、すなわち前記回転分離容器（１０）の軸心側に分離浮上する。 The polluted liquid led into the staying liquid surface is separated into the inner surface side of the rotary separation container (10) by centrifugal force and the operation of the pollutant synchronizing fin portion (423) of the pollutant diffusion synchronizing unit. The oil component that has settled and has a specific gravity of less than 1 separates and floats on the upper surface side of the separated and settled water component, that is, on the axial center side of the rotary separation container (10).
その後の動作は、同様であるので省略する。 Subsequent operations are the same and will be omitted.
実施例４の遠心分離装置は、実施例２の遠心分離装置をベースに分離動作の改善を図り分離性能を向上させた実施例３の遠心分離装置の変形例である。 The centrifuge of the fourth embodiment is a modification of the centrifuge of the third embodiment in which the separation performance is improved by improving the separation operation based on the centrifuge of the second embodiment.

A rotary separation container drive mechanism as a source, a contaminated concentrate introduction pipe that passes through the axial center of the rotary separation container, a circular swing plate top surface portion located immediately below the contaminated concentrate introduction pipe, and the shaking Cylindrical shaking plate side surface hanging downward from the circumferential side surface of the plate top surface portion, and a plurality of pollutant synchronizing fins protruding vertically in the vertical direction on the outer surface of the side surface portion of the shaking plate The liquid dispersion synchronization unit composed of a part, a sludge guard for preventing sludge from entering the top surface of the shaking plate, and scraping off the solid deposited on the inner surface of the rotary separation container A solid discharge mechanism that discharges the liquid to the outside, a light liquid discharge passage that guides light liquid with a low specific gravity from the inside of the rotary separation container to the outside, and a heavy liquid with a high specific gravity from the inside to the outside of the rotary separation container And a residual liquid discharge channel that guides the residual liquid from the inside to the outside of the rotary separation container.
その他の構成については、実施例３と同様であるので省略する。 Other configurations are the same as those in the third embodiment, and are omitted.
また、動作についても実施例３と略同様であるので省略する。 Further, the operation is substantially the same as that of the third embodiment, and therefore will be omitted.
本願発明の遠心分離装置は、汚濁原液に固体成分が含まれ得る場合であっても比重差を利用して２液に分離排出するとともに、固体成分をも簡易に除去排出できるため、保守性等を飛躍的に向上させる装置であるので、産業上の利用性を有する。 Since the centrifugal separator of the present invention can separate and discharge into two liquids using the difference in specific gravity even when the solid component can be contained in the contaminated undiluted solution, the solid component can be easily removed and discharged. Therefore, it has industrial applicability.
