Description

この発明は、微細金属粉および金属粒などを、気泡を含む洗浄液を用いて洗浄する洗浄装置に関するものである。主として切削屑などの脱脂洗浄に関するものであるが、これに限定されるものではなく、例えば小型ベアリング球、子ネジ、小型設定材などの微細な金属加工品に付着する油脂や粉塵などの除去洗浄にも適用することができる。 The present invention relates to a cleaning apparatus for cleaning fine metal powder, metal particles, and the like using a cleaning liquid containing bubbles. This is mainly related to degreasing and cleaning of cutting scraps, but is not limited to this. For example, removal and cleaning of oil and grease adhering to fine metal workpieces such as small bearing balls, small screws and small setting materials. It can also be applied to.

過去、工業洗浄の分野ではフロン系の溶剤や有機溶剤、そのほか炭化水素系などの洗浄剤が用いられてきた。その結果、オゾン層の破壊や地下水、河川、海洋汚染などの環境問題を誘起することが明らかにされてきた。そのため、環境負荷低減の目的からこれらの洗浄剤を用いない洗浄方法および洗浄装置の開発が進められている。また、被洗浄物としては、金属加工物をはじめとする部品、製品のみならず、これらの加工時に発生する切削屑などについても、環境負荷に配慮した廃棄あるいは再利用が進められ、金属の粉体・粒体状の被洗浄物を効率的に洗浄できる装置が望まれている。 In the past, in the field of industrial cleaning, chlorofluorocarbon solvents, organic solvents, and other hydrocarbon cleaning agents have been used. As a result, it has been clarified that it induces environmental problems such as ozone layer destruction and groundwater, river, and ocean pollution. Therefore, development of a cleaning method and a cleaning apparatus that do not use these cleaning agents is being promoted for the purpose of reducing the environmental burden. In addition, not only parts and products, including metal workpieces, but also scraps generated during these processes are being disposed or reused in consideration of environmental impacts as the objects to be cleaned. There has been a demand for an apparatus capable of efficiently cleaning a body / granular object to be cleaned.

切削屑などの金属粉や金属粒を洗浄する方法としては、従来からイソプロピルアルコールまたはアセトンで洗浄することにより脱脂するものが提案されている（例えば、特許文献１参照）。しかし、この方法では洗浄のための溶剤としてイソプロピルアルコールやアセトンという有機溶剤を使用しており、これらの有機溶剤がオゾン層の破壊や地下水、河川、海洋汚染などの環境問題を誘起することが明らかにされてきた昨今、環境負荷低減の目的から、これらの洗浄剤を用いない洗浄方法および洗浄装置が望ましい。 As a method for cleaning metal powder such as cutting waste and metal particles, a method of degreasing by washing with isopropyl alcohol or acetone has been proposed (for example, see Patent Document 1). However, in this method, organic solvents such as isopropyl alcohol and acetone are used as cleaning solvents, and it is clear that these organic solvents induce environmental problems such as destruction of the ozone layer, groundwater, rivers, and ocean pollution. In recent years, cleaning methods and apparatuses that do not use these cleaning agents are desirable for the purpose of reducing environmental impact.

これらの観点から、水と微細気泡により被洗浄物に付着した油脂などを除去する技術として、被洗浄物を収納する被洗浄物容器を洗浄液に浸漬し、当該被洗浄物容器を回転させながら気泡発生部から噴出する微細気泡と洗浄液の混合体を被洗浄物に接触させることによって被洗浄物に付着した油脂などを除去する装置が提案されている（例えば、特許文献２参照）。 From these viewpoints, as a technique for removing oils and fats adhering to the object to be cleaned by water and fine bubbles, the object container containing the object to be cleaned is immersed in the cleaning liquid, and the bubbles are rotated while rotating the object container to be cleaned. There has been proposed an apparatus for removing oils and fats adhering to an object to be cleaned by bringing a mixture of fine bubbles ejected from the generating part and the cleaning liquid into contact with the object to be cleaned (see, for example, Patent Document 2).

しかし、特許文献２に開示された装置では被洗浄物を被洗浄物容器に収容して洗浄する必要があり、切削屑などの微細な金属粉状の被洗浄物を洗浄するには、被洗浄物容器の網目が微細になり、微細気泡と洗浄液が被洗浄物に接触する速度が阻害され洗浄能力が低下するという問題があった。また、この種の装置では、洗浄後に洗浄物容器を引き上げて搬出する必要があり、洗浄液の上部に浮上し残留している油脂分を含む気泡との接触による再付着の問題があった。さらに、一定量の被洗浄物を被洗浄物容器に入れて洗浄するため、洗浄処理はバッチ処理となり、被洗浄物の出し入れに人手が必要となるという問題があった。 However, in the apparatus disclosed in Patent Document 2, the object to be cleaned must be accommodated in the object to be cleaned and cleaned. There is a problem that the mesh of the container becomes fine, the speed at which the fine bubbles and the cleaning liquid come into contact with the object to be cleaned is hindered, and the cleaning ability is lowered. Further, in this type of apparatus, it is necessary to pull up and carry out the cleaning object container after cleaning, and there is a problem of redeposition due to contact with bubbles containing oil and fat floating on the upper part of the cleaning liquid. Furthermore, since a certain amount of the object to be cleaned is put into the object to be cleaned and cleaned, the cleaning process becomes a batch process, and there is a problem that manpower is required to put in and out the object to be cleaned.

連続処理を可能とし自動化するための装置としては、傾斜したエンドレスチェーンコンベアに切削屑を収容する洗浄カゴを取付け、これを間欠的に移動させて無機水溶液浸漬、散水洗浄、脱水の工程を順次処理する装置が提案されている（例えば、特許文献３参照）。 As a device that enables continuous processing and automates it, a cleaning basket containing cutting waste is attached to an inclined endless chain conveyor, and this is moved intermittently to sequentially process the steps of immersion in inorganic aqueous solution, sprinkling cleaning, and dehydration. An apparatus has been proposed (see, for example, Patent Document 3).

以下、この発明の実施の形態について図面を参照しながら詳細に説明する。
実施の形態１．
図１は、この発明の実施の形態１に係る洗浄装置の構成を示す断面図であり、図２は、この発明の実施の形態１に係る洗浄装置の構成を示す部分断面図である。なお、以下では、主として金属切削屑などを被洗浄物とする洗浄に最適な実施例を示すが、被洗浄物はこれに限定されるものではない。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Embodiment 1 FIG.
FIG. 1 is a cross-sectional view showing the configuration of the cleaning apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a partial cross-sectional view showing the configuration of the cleaning apparatus according to Embodiment 1 of the present invention. In the following, an embodiment that is optimal for cleaning mainly using metal cutting waste or the like is shown, but the object to be cleaned is not limited to this.

実施の形態１の洗浄装置は、円筒形状を有し被洗浄物を洗浄する洗浄槽１０、気液混合エジェクタ（洗浄手段）２０、被洗浄物と洗浄液を混合する混合槽３０、洗浄槽１０の上部外側に配置されるオーバーフロー槽４０、洗浄後の洗浄液を分離する油水分離槽（油水分離手段）５０、および被洗浄物の水切りを行う水切り槽６０などで構成される。洗浄槽１０は円筒形状の軸方向の中央部付近に中央に開口部を有する第１の仕切り１１および第２の仕切り１２を有している。洗浄槽１０内部に、第１の仕切り１１および第２の仕切り１２を設けることにより被洗浄物が旋回しながら通過する旋回状の流路部１４が形成される。洗浄槽１０上部にはメッシュ状の微細な穴をもつ板状の微細メッシュ部材１５が設置されており、微細気泡と一緒に被洗浄物が上昇し、洗浄槽１０外へ流れてしまうのを防ぐ。 The cleaning apparatus according to the first embodiment includes a cleaning tank 10 having a cylindrical shape for cleaning an object to be cleaned, a gas-liquid mixing ejector (cleaning means) 20, a mixing tank 30 for mixing an object to be cleaned and a cleaning liquid, and a cleaning tank 10. An overflow tank 40 disposed on the upper outer side, an oil / water separation tank (oil / water separation means) 50 for separating the washed liquid after washing, and a draining tank 60 for draining an object to be washed. The cleaning tank 10 has a first partition 11 and a second partition 12 having an opening at the center near the axial center of the cylindrical shape. By providing the first partition 11 and the second partition 12 inside the cleaning tank 10, a swirl-shaped flow path portion 14 through which the object to be cleaned passes while swirling is formed. A plate-like fine mesh member 15 having fine mesh-like holes is installed in the upper part of the washing tank 10 to prevent the object to be washed from rising together with the fine bubbles and flowing out of the washing tank 10. .

ここで、微細気泡とは、球状となる微細な気泡のことである。微細気泡と異なる通常の大きな気泡は、水中を浮上するときに受ける水からの抗力によって球状ではなく歪んだ形となる。これに対して、微細気泡は、気泡内部の圧力が高いため水の抗力による歪みがなく球状となることが広く知られている。具体的には、気泡径ｄが１ｍｍ以下となる場合に気泡は球状となる。さらに洗浄液には、微細気泡を安定に維持する効果を有するアルコール系化合物や界面活性剤などの添加剤を添加している。例えば、添加剤の具体例としては、カルボキシル基とアミノ基を分子内に持ち、分子量をカルボキシル基の数で割った値が９４以上２８０以下の物質、分子内に水酸基を複数持ち、分子量を水酸基の数で割った値が３８以上７３以下の物質、分子内にエステル基を持ち、分子量をエステル基の数で割った値が４７以上１４０以下の物質、あるいは、分子内にスルホン酸基を持ち、分子量をスルホン酸基の数で割った値が４７以上１４０以下の物質が挙げられる。これらの添加剤を、洗浄液中に微量添加（０．００１ｍｏｌ／Ｌ以上１ｍｏｌ／Ｌ以下）することにより、微細気泡を安定に維持する効果を発揮する。 Here, the fine bubbles are fine bubbles that are spherical. A normal large bubble different from a fine bubble has a distorted shape instead of a spherical shape due to a drag from the water that is received when it floats in the water. On the other hand, it is widely known that fine bubbles are spherical without distortion due to water drag due to high pressure inside the bubbles. Specifically, when the bubble diameter d is 1 mm or less, the bubbles are spherical. Furthermore, additives such as alcohol compounds and surfactants having an effect of stably maintaining fine bubbles are added to the cleaning liquid. For example, specific examples of the additive include a substance having a carboxyl group and an amino group in the molecule, the molecular weight divided by the number of carboxyl groups being 94 to 280, a molecule having a plurality of hydroxyl groups, and a molecular weight of the hydroxyl group. A substance divided by the number of 38 to 73 or less, having an ester group in the molecule, and a substance having a molecular weight divided by the number of ester groups of 47 to 140 or having a sulfonic acid group in the molecule And a substance having a molecular weight divided by the number of sulfonic acid groups of 47 or more and 140 or less. By adding a small amount of these additives into the cleaning liquid (0.001 mol / L or more and 1 mol / L or less), the effect of stably maintaining fine bubbles is exhibited.

また、第１の仕切り１１の開口部の面積は、第２の仕切り１２の開口部の面積よりも大きくなるように形成されている。これにより、旋回状の流路部１４の上側の洗浄液の旋回を激しく、下側の洗浄液の旋回を緩やかに構成することができる。さらに、第２の仕切り１２は、外周面に洗浄槽１０の内周壁との間に複数の外周開口部１３を形成する凹部を有している。 The area of the opening of the first partition 11 is formed to be larger than the area of the opening of the second partition 12. Thereby, the swirling of the cleaning liquid on the upper side of the swirling flow path portion 14 can be intense, and the swirling of the lower cleaning liquid can be gently configured. Further, the second partition 12 has a recess that forms a plurality of outer peripheral openings 13 between the outer peripheral surface and the inner peripheral wall of the cleaning tank 10.

気液混合エジェクタ２０は、洗浄槽１０の外部から内周壁に沿う方向に挿通するように配設されている。気液混合エジェクタ２０は両端に開口部が形成され、一方の開口部は洗浄槽１０内に位置している。他方の洗浄槽１０の外側に位置する開口部は、圧縮水導入管２１を介して水ポンプ２２が接続され、圧縮空気導入管２３を介して空気ポンプ２４が接続されている。この水ポンプ２２および空気ポンプ２４を用いることにより、洗浄槽１０の旋回状の流路部１４に気液混合体を噴出させて旋回流を形成するように構成されている。また、気泡混合エジェクタ２０と圧縮水導入管２１の接続口の近傍には、微細な被洗浄物が混入して詰まった場合などに自動的に詰まりを検知する詰まり検知部２５が設けられている。さらに、気泡混合エジェクタ２０と圧縮空気導入管２３の接続口の近傍には、洗浄液の逆流を防ぐための逆止弁２６が設けられている。 The gas-liquid mixing ejector 20 is disposed so as to be inserted from the outside of the cleaning tank 10 in a direction along the inner peripheral wall. The gas-liquid mixing ejector 20 has openings at both ends, and one opening is located in the cleaning tank 10. The opening located outside the other washing tank 10 is connected to a water pump 22 via a compressed water introduction pipe 21 and to an air pump 24 via a compressed air introduction pipe 23. By using the water pump 22 and the air pump 24, the gas-liquid mixture is ejected into the swirling flow path portion 14 of the cleaning tank 10 to form a swirling flow. Further, a clogging detection unit 25 that automatically detects clogging when a minute object to be cleaned is clogged is provided near the connection port between the bubble mixing ejector 20 and the compressed water introduction pipe 21. . Further, a check valve 26 for preventing the backflow of the cleaning liquid is provided in the vicinity of the connection port between the bubble mixing ejector 20 and the compressed air introduction pipe 23.

図３は、この発明の実施の形態１に係る洗浄槽の構成を示す図である。気液混合エジェクタ２０は、一個乃至複数個を配置する。図３の例では、気液混合エジェクタ２０を洗浄槽１０の外周に対して等間隔に４箇所設け、洗浄槽１０の内側に位置する開口部を全て反時計周り方向に向けて配置している。このように配置することにより、水ポンプ２２および空気ポンプ２４を用いて気液混合体を噴出させると、矢印Ａで示す反時計周りの旋回流が形成される。なお、気液混合エジェクタ２０へ供給する空気は空気ポンプ２４による圧縮空気の他、気液混合エジェクタ２０の絞り構造の効果による自然吸気による方法としてもよい。第２の仕切り１２の外周開口部１３は、外周部に等間隔に４箇所設けられている。 FIG. 3 is a diagram showing the configuration of the cleaning tank according to Embodiment 1 of the present invention. One or more gas-liquid mixing ejectors 20 are arranged. In the example of FIG. 3, the gas-liquid mixing ejectors 20 are provided at four locations at regular intervals with respect to the outer periphery of the cleaning tank 10, and all the openings located inside the cleaning tank 10 are arranged in the counterclockwise direction. . With this arrangement, when the gas-liquid mixture is ejected using the water pump 22 and the air pump 24, a counterclockwise swirling flow indicated by an arrow A is formed. The air supplied to the gas-liquid mixing ejector 20 may be a method using natural intake due to the effect of the throttle structure of the gas-liquid mixing ejector 20 in addition to the compressed air by the air pump 24. Four outer peripheral openings 13 of the second partition 12 are provided at equal intervals on the outer peripheral portion.

混合槽３０は、上部から導入される被洗浄物と洗浄液を混合する槽である。混合槽３０は、洗浄槽１０の第１の仕切り１１の上部と連通する混合槽連通管３１を有し、この混合槽連通管３１を介して洗浄槽１０内の洗浄液を混合槽３０内に取り込む。また、混合槽３０下部から延びる被洗浄物投入管（被洗浄物投入手段）３２によって洗浄槽１０内の旋回状の流路部１４と連通している。この被洗浄物投入管３２の洗浄槽１０内に位置する開口部（被洗浄物投入口）には負圧発生手段３３が設けられている。 The mixing tank 30 is a tank that mixes an object to be cleaned and a cleaning liquid introduced from above. The mixing tank 30 has a mixing tank communication pipe 31 that communicates with the upper part of the first partition 11 of the cleaning tank 10, and the cleaning liquid in the cleaning tank 10 is taken into the mixing tank 30 through the mixing tank communication pipe 31. . Further, a cleaning object input pipe (object to be cleaned input means) 32 extending from the lower part of the mixing tank 30 communicates with the swirling flow path portion 14 in the cleaning tank 10. A negative pressure generating means 33 is provided at an opening (object to be cleaned input port) located in the cleaning tank 10 of the object charging pipe 32.

図４は、この発明の実施の形態１に係る負圧発生手段の構成を示す図である。図４（ａ）に示す負圧発生手段３３ａは、流線形状の覆いであり、洗浄槽１０内部に挿入された被洗浄物投入管３２の先端開口部を覆うように配設し、旋回状の流路部１４の旋回流Ａの下流側を開口して設けている。また、図４（ｂ）に示す負圧発生手段３３ｂは、被洗浄物投入管３２の先端開口部付近の洗浄槽１０の内周壁に設けられた凹部である。この凹部を旋回流Ａが通過する際に局部的に旋回流速が低下し、負圧が発生する。このように、負圧発生手段３３は、旋回状の流路部１４に負圧を発生させる構成であれば適宜変更可能である。 FIG. 4 is a diagram showing the configuration of the negative pressure generating means according to Embodiment 1 of the present invention. The negative pressure generating means 33a shown in FIG. 4 (a) is a streamlined cover, and is disposed so as to cover the tip opening of the cleaning object charging pipe 32 inserted into the cleaning tank 10, and has a swirling shape. An opening is provided on the downstream side of the swirling flow A of the flow path section 14. Further, the negative pressure generating means 33b shown in FIG. 4 (b) is a recess provided in the inner peripheral wall of the cleaning tank 10 in the vicinity of the opening of the tip of the cleaning object input pipe 32. When the swirling flow A passes through this recess, the swirling flow velocity is locally reduced, and negative pressure is generated. Thus, the negative pressure generating means 33 can be appropriately changed as long as it is configured to generate a negative pressure in the swirling flow path portion 14.

オーバーフロー槽４０は、洗浄槽１０の上部外側に配置され、洗浄槽１０と同様に円筒形状を有している。このオーバーフロー槽４０は、洗浄槽１０の上端部から溢れ出る洗浄液を受け止め、受け止めた洗浄液を送液管４１を介して油水分離槽５０に排出する。 The overflow tank 40 is disposed outside the upper part of the cleaning tank 10 and has a cylindrical shape like the cleaning tank 10. The overflow tank 40 receives the cleaning liquid overflowing from the upper end of the cleaning tank 10 and discharges the received cleaning liquid to the oil / water separation tank 50 via the liquid feeding pipe 41.

油水分離槽５０は、第１の仕切り板５１と第２の仕切り板５２により第１分離槽５３、第２分離槽５４、第３分離槽５５の少なくとも３槽に分離して構成される。第１の仕切り板５１は油水分離槽５０の底部に接合され、第１分離槽５３と第２分離槽５４は上部で連通している。第２の仕切り板５２は油水分離槽５０の底部に接合されておらず、第２の分離５４と第３の分離槽５５が下部で連通している。これらの構成により、油脂分が第１分離槽５３および第２分離槽５４の上部に留まり、油脂分を含まない洗浄液を第３分離槽５５に溜めることができる。第３分離槽５５の中央部付近に水ポンプ２２に接続された排出管５６が挿入され、第３分離槽５５の油脂分を含まない洗浄液を洗浄槽１０内へ循環させることができる。また、第２分離槽５４には水平方向の仕切り板５７が設置され、気泡巻き込みを防止する。 The oil / water separation tank 50 is configured to be separated into at least three tanks of a first separation tank 53, a second separation tank 54, and a third separation tank 55 by a first partition plate 51 and a second partition plate 52. The 1st partition plate 51 is joined to the bottom part of the oil-water separation tank 50, and the 1st separation tank 53 and the 2nd separation tank 54 are connected by the upper part. The second partition plate 52 is not joined to the bottom of the oil / water separation tank 50, and the second separation 54 and the third separation tank 55 communicate with each other at the lower part. With these configurations, the oil and fat remains in the upper part of the first separation tank 53 and the second separation tank 54, and a cleaning liquid that does not contain the oil and fat can be stored in the third separation tank 55. A discharge pipe 56 connected to the water pump 22 is inserted in the vicinity of the center of the third separation tank 55, and the cleaning liquid that does not contain oil and fat in the third separation tank 55 can be circulated into the cleaning tank 10. Moreover, the horizontal partition plate 57 is installed in the 2nd separation tank 54, and bubble entrainment is prevented.

洗浄槽１０の下部は円錐状に絞られ、円錐状の先端部分に略Ｌ字形状に形成した被洗浄物溜まり１６、この被洗浄物溜まり１６の先端部分には、搬出量調節絞り１７ａを有し、洗浄後の被洗浄物を洗浄液と共に洗浄槽１０外部に搬出する搬出口１７が形成されている。搬出量調節絞り１７ａは、洗浄槽１０に投入される被洗浄物の量と、気液混合エジェクタ２０から流入する洗浄液の量に基づき搬出量を調節するための絞りである。 The lower part of the cleaning tank 10 is constricted in a conical shape, and a cleaning object reservoir 16 formed in a substantially L shape at the conical tip portion, and a carry-out amount adjusting throttle 17a is provided at the leading end portion of the cleaning object reservoir 16. In addition, a carry-out port 17 is formed for carrying out the washed object together with the washing liquid to the outside of the washing tank 10. The carry-out amount adjusting throttle 17 a is a throttle for adjusting the carry-out amount based on the amount of the object to be cleaned put into the cleaning tank 10 and the amount of the cleaning liquid flowing from the gas-liquid mixing ejector 20.

搬出口１７の下方には、搬出された被洗浄物と洗浄液の混合体から被洗浄物を濾し取るフィルタ６１を有する水切り槽６０が配設されている。このフィルタ６１には振動印加部６２が付属されている。これにより、フィルタ６１による水切りが促進される。また、水切り層６０には、水洗が必要な場合のためのすすぎ水供給部６３、および被洗浄物の乾燥性向上のための乾燥ブロア６４が設けられている。さらに、水切り槽６０の底部付近に排出管６５が挿入されている。フィルタ６１により水切りされて回収された洗浄液が、排出管６５およびこの排出管６５が接続されている循環ポンプ６６を介して、油水分離槽５０の第１分離槽５３に導入される。 Below the carry-out port 17, a draining tank 60 having a filter 61 for filtering out the object to be cleaned from the mixture of the object to be cleaned and the cleaning liquid is disposed. A vibration applying unit 62 is attached to the filter 61. Thereby, draining by the filter 61 is promoted. Further, the draining layer 60 is provided with a rinsing water supply part 63 for the case where water washing is necessary, and a drying blower 64 for improving the drying property of the object to be washed. Further, a discharge pipe 65 is inserted near the bottom of the draining tank 60. The cleaning liquid drained and collected by the filter 61 is introduced into the first separation tank 53 of the oil / water separation tank 50 through the discharge pipe 65 and the circulation pump 66 to which the discharge pipe 65 is connected.

次に、この実施の形態１に係る洗浄装置の動作について説明する。図３で示したように気液混合エジェクタ２０は、円筒状の洗浄槽１０の内周に沿って４箇所に取り付けられているため、この気液混合エジェクタ２０から噴出する洗浄液と微細気泡の混合体は、旋回状の流路部１４内で激しく旋回する気液混合流体となる。一方、混合槽３０の上部から被洗浄物が投入されると、旋回状の流路部１４に連通する被洗浄物投入管３２と旋回状の流路部１４に設けた負圧発生手段３３により発生する負圧の効果によって、混合槽３０内の被洗浄物と洗浄液の混合体が洗浄槽１０内へ吸引され、旋回状の流路部１４内へ投入される。また、混合槽連通管３１を介して洗浄液が混合槽３０に流入し、混合槽３０内部で洗浄液と被洗浄物が混合される。 Next, the operation of the cleaning apparatus according to the first embodiment will be described. As shown in FIG. 3, the gas-liquid mixing ejector 20 is attached at four locations along the inner periphery of the cylindrical cleaning tank 10, so that the cleaning liquid ejected from the gas-liquid mixing ejector 20 is mixed with fine bubbles. The body becomes a gas-liquid mixed fluid that swirls vigorously in the swirl-shaped flow path portion 14. On the other hand, when an object to be cleaned is input from the upper part of the mixing tank 30, the object to be cleaned input pipe 32 communicating with the swirling flow path portion 14 and the negative pressure generating means 33 provided in the swirling flow path portion 14. Due to the generated negative pressure effect, the mixture of the object to be cleaned and the cleaning liquid in the mixing tank 30 is sucked into the cleaning tank 10 and introduced into the swirling channel portion 14. In addition, the cleaning liquid flows into the mixing tank 30 through the mixing tank communication pipe 31, and the cleaning liquid and the object to be cleaned are mixed inside the mixing tank 30.

旋回状の流路部１４内に投入された被洗浄物は、気液混合エジェクタ２０から供給される高速の洗浄液および微細気泡と激しく衝突しながら、付着した油脂分が剥離され微細気泡に吸着されていく。これにより、特別な攪拌手段や加速手段を設けることなく、短時間で効率的に被洗浄物を洗浄することができる。
さらに洗浄効果を高めるためには旋回状の流路部１４の角度を適宜変更できようにしておくとよい。これは微細気泡と被洗浄物との接触確率を向上させるためである。また旋回状の流路部１４に流れを乱すための部材、たとえば平板などを部材に対して数１０度以上、９０度以下の角度で設置してもよい。これにより、前述のように流れを乱す以外に、被洗浄物が一時的に平板でせき止められ、その間に微細気泡が接触することで洗浄力が高まる効果にもつながる。 The object to be cleaned put into the swirl-shaped flow path portion 14 violently collides with the high-speed cleaning liquid and fine bubbles supplied from the gas-liquid mixing ejector 20, and the attached oil and fat are separated and adsorbed by the fine bubbles. To go. As a result, the object to be cleaned can be efficiently cleaned in a short time without providing any special stirring means or acceleration means.
In order to further enhance the cleaning effect, it is preferable that the angle of the swirling channel portion 14 can be changed as appropriate. This is to improve the contact probability between the fine bubbles and the object to be cleaned. Further, a member for disturbing the flow, such as a flat plate, may be installed in the swirling channel portion 14 at an angle of several tens of degrees or more and 90 degrees or less. As a result, in addition to disturbing the flow as described above, the object to be cleaned is temporarily blocked by the flat plate, and the fine bubbles come into contact therewith, leading to the effect of increasing the cleaning power.

旋回状の流路部１４内では、洗浄液と微細気泡および被洗浄物の旋回に伴って、油脂分を吸着した微細気泡は水との比重差による効果に伴い旋回流の中央部分に集積し、旋回状の流路部１４の上側に設けた第１の仕切り１１の中央開口部から洗浄槽１０の上部に向かって上昇する。 In the swirl-shaped flow path section 14, as the cleaning liquid, fine bubbles, and the object to be cleaned are swirled, the fine bubbles that have adsorbed oil and fat accumulate in the central portion of the swirl flow due to the effect of the specific gravity difference with water. Ascending from the central opening of the first partition 11 provided on the upper side of the swirling flow path portion 14 toward the upper portion of the cleaning tank 10.

一方、旋回状の流路部１４内を旋回する被洗浄物は水との比重差による効果に伴い、旋回状の流路部１４の外周部分を旋回すると共に、旋回状の流路部１４の下側に設けた第２の仕切り１２の外周開口部１３から洗浄槽１０の下部に向かって沈降する。このように、被洗浄物は旋回状の流路部１４を旋回しながら洗浄され、油脂を含む気泡は旋回状の流路部１４の上側へ、洗浄された被洗浄物は旋回状の流路部１４の下側に分離されることにより、洗浄後の被洗浄物への油脂の再付着を抑制することができる。 On the other hand, the cleaning object swirling in the swirling flow path portion 14 swirls around the outer periphery of the swirling flow path portion 14 due to the effect of the specific gravity difference with water. It sinks toward the lower part of the washing tank 10 from the outer periphery opening part 13 of the 2nd partition 12 provided in the lower side. In this way, the object to be cleaned is cleaned while swirling the swirl-shaped flow path part 14, bubbles containing oil and fat are moved to the upper side of the swirl-shaped flow path part 14, and the cleaned object to be cleaned is swirl-shaped flow path. Separation to the lower side of the portion 14 can suppress the reattachment of fats and oils to the object to be cleaned after cleaning.

次に、旋回状の流路部１４の上側に移動した微細気泡と旋回流の動きについて説明する。図５は、この発明の実施の形態１に係る洗浄装置における微細気泡と旋回流の流れを示す図である。洗浄槽１０上部では、旋回状の流路部１４の上側に位置する第１の仕切り１１の中央開口部を通じて旋回状の流路部１４の高速旋回流につれて旋回する流れが発生する。図４に示すように、この旋回流は洗浄液が旋回の外側に分布し、気体が旋回の中央部に分布する気液二層流となるため、油脂を含む微細気泡は中央部に集積されて上昇する。旋回流の水面に達した微細気泡は、洗浄槽１０の上端外周部へ向かう水の流れに乗って洗浄槽１０の上端からオーバーフロー流となってオーバーフロー槽４０へ流出する。このように、油脂を含む微細気泡は速やかにオーバーフロー槽４０へ移動するため、効果的に油脂分を排出することができ、常に洗浄液を清浄に保つことができる。 Next, the movement of the fine bubbles and the swirling flow that have moved to the upper side of the swirling flow path portion 14 will be described. FIG. 5 is a diagram showing the flow of fine bubbles and a swirling flow in the cleaning apparatus according to Embodiment 1 of the present invention. In the upper part of the cleaning tank 10, a swirling flow is generated along with the high-speed swirling flow of the swirling flow path portion 14 through the central opening of the first partition 11 located above the swirling flow path portion 14. As shown in FIG. 4, since this swirl flow is a gas-liquid two-layer flow in which the cleaning liquid is distributed outside the swirl and the gas is distributed in the central part of the swirl, fine bubbles containing oil and fat are accumulated in the central part. To rise. The fine bubbles that have reached the swirling water surface ride on the flow of water toward the outer periphery of the upper end of the cleaning tank 10 and flow out of the upper end of the cleaning tank 10 into the overflow tank 40 as an overflow flow. In this way, since the fine bubbles containing the oil and fat move quickly to the overflow tank 40, the oil and fat can be effectively discharged, and the cleaning liquid can always be kept clean.

オーバーフロー槽４０へ流入した洗浄液は、送液管４１を介して油水分離槽５０へ導入される。第１分離槽５３では、流入する洗浄液の勢いが強く洗浄液が攪拌される。第１分離槽５３と第２分離槽５４は第１の仕切り板５１によって仕切られているため、第２分離槽５４内の洗浄液は静置された状態となり、洗浄液に含まれる油脂分および油脂分を吸着した気泡は第２分離槽５４の表面に浮上する。 The cleaning liquid that has flowed into the overflow tank 40 is introduced into the oil / water separation tank 50 via the liquid supply pipe 41. In the first separation tank 53, the cleaning liquid flowing in is strong and the cleaning liquid is stirred. Since the 1st separation tank 53 and the 2nd separation tank 54 are partitioned off by the 1st partition plate 51, the washing | cleaning liquid in the 2nd separation tank 54 will be in the state left still, and the oil-fat content and oil-fat content which are contained in a washing | cleaning liquid The bubbles adsorbed on the surface float on the surface of the second separation tank 54.

一方、第２分離槽５４の底部にある浄化された洗浄液は第２の仕切り板５２の下部を通じて第３分離槽５５へ流入する。浮遊する油脂分を含む気泡が取り除かれた第３分離槽５５では、その中央付近に挿入された排出管５６により油水分離槽５０の外部へ取り出され、水ポンプ２２により気液混合エジェクタ２０へ循環される。これにより、気液混合エジェクタ２０から噴出される洗浄液は常に清浄が保たれる。なお、油水分離槽５０の第１分離槽５３および第２分離槽５４の上部表面に浮遊する油脂分は、オイルスキマーあるいは油膜層排出経路などによる公知の方法により回収することができる。 On the other hand, the purified cleaning liquid at the bottom of the second separation tank 54 flows into the third separation tank 55 through the lower part of the second partition plate 52. In the third separation tank 55 from which air bubbles containing floating oil and fat components have been removed, it is taken out of the oil / water separation tank 50 by a discharge pipe 56 inserted near its center and circulated to the gas-liquid mixing ejector 20 by the water pump 22. Is done. Thereby, the cleaning liquid ejected from the gas-liquid mixing ejector 20 is always kept clean. In addition, the fats and oils floating on the upper surfaces of the first separation tank 53 and the second separation tank 54 of the oil / water separation tank 50 can be recovered by a known method such as an oil skimmer or an oil film layer discharge path.

次に、洗浄槽１０の下側に移動した被洗浄物の搬出動作について説明する。旋回状の流路部１４の下側に位置する第２の仕切り１２に設けた外周開口部１３を経て洗浄槽１０の下側に移動した洗浄後の被洗浄物は、緩やかに旋回しながら洗浄槽１０下部の被洗浄物溜まり１６に沈降する。沈降した被洗浄物は、搬出量調節絞り１７ａにより洗浄液と共に搬出口１７から水切り槽６０へ流出する。搬出量調節絞り１７ａは、少なくとも気液混合エジェクタ２０からの洗浄液の流入量よりも少ない量の流出量に調節する。また、洗浄槽１０への被洗浄物の投入量は、被洗浄物溜まり１６に被洗浄物が滞らない程度に調節することが望ましい。 Next, the carrying-out operation of the cleaning object moved to the lower side of the cleaning tank 10 will be described. The object to be cleaned that has moved to the lower side of the cleaning tank 10 through the outer peripheral opening 13 provided in the second partition 12 positioned below the swirling flow path portion 14 is washed while gently swirling. It settles in the object pool 16 at the bottom of the tank 10. The object to be cleaned that has settled flows out from the carry-out port 17 to the draining tank 60 together with the cleaning liquid by the carry-out amount adjusting throttle 17a. The carry-out amount adjusting throttle 17a adjusts to an outflow amount that is at least smaller than the inflow amount of the cleaning liquid from the gas-liquid mixing ejector 20. Further, it is desirable to adjust the amount of the object to be cleaned to the cleaning tank 10 so that the object to be cleaned does not stagnate in the object reservoir 16.

水切り槽６０へ流出した被洗浄物は、水切り槽６０の上部に設けたフィルタ６１により水切りが行われる。また、水切り槽６０の下部に溜まった洗浄液は、排出管６５から排出され、循環ポンプ６６を経由して油水分離槽５０の第１分離槽５３に循環される。なお、水切り槽６０の排出管６５の内側に仕切り板を設けてもよく、この仕切り板により、汚れや小さな異物を含んだ洗浄液が循環ポンプ６６を介して油水分離槽５０に循環されることを防ぐことができる。また、循環ポンプ６６を設けることなく、水切り槽６０と油水分離槽５０の設置位置の高低差により自然流下する方法で構成してもよい。 The object to be cleaned that has flowed into the draining tank 60 is drained by a filter 61 provided at the top of the draining tank 60. Further, the cleaning liquid accumulated in the lower part of the draining tank 60 is discharged from the discharge pipe 65 and is circulated to the first separation tank 53 of the oil / water separation tank 50 via the circulation pump 66. In addition, a partition plate may be provided inside the discharge pipe 65 of the draining tank 60, and the partition plate allows the cleaning liquid containing dirt and small foreign matters to be circulated to the oil / water separation tank 50 via the circulation pump 66. Can be prevented. Moreover, you may comprise by the method of flowing naturally by the height difference of the installation position of the draining tank 60 and the oil-water separation tank 50, without providing the circulation pump 66.

以上のように、この実施の形態１によれば、洗浄槽１０内に少なくとも２枚以上の仕切り１１，１２を設け、当該仕切り１１，１２によって形成される旋回状の流路部１４内に被洗浄物を投入して旋回状の流路部１４を旋回する洗浄液および微細気泡が直接接触させ、さらに気液混合エジェクタ２０から噴出する気液混合体の流速によって旋回流を発生させ、微細気泡と被洗浄物が激しく接触するように構成したので、特別な攪拌手段や加速度手段を設けることなく簡単な構成により効率的に被洗浄物の洗浄を行うことができる。 As described above, according to the first embodiment, at least two or more partitions 11, 12 are provided in the cleaning tank 10, and the covered channel portion 14 formed by the partitions 11, 12 is covered. The cleaning liquid and fine bubbles that are swirled in the swirl-shaped flow path portion 14 after directing the cleaning material are brought into direct contact with each other, and a swirling flow is generated by the flow velocity of the gas-liquid mixture ejected from the gas-liquid mixing ejector 20. Since the object to be cleaned is configured to come into intense contact, the object to be cleaned can be efficiently cleaned with a simple configuration without providing any special stirring means or acceleration means.

また、この実施の形態１によれば、第１の仕切り１１の中央に開口部を設け、旋回状の流路部１４の上側に気液二層流を発生させるように構成したので、油脂分を吸着した微細気泡は洗浄槽１０の中心部に集まって上昇し、洗浄槽１０水面に達した時に洗浄槽１０上端外周部へ向かう水流に乗って移動し、速やかにオーバーフローさせることができる。これにより洗浄に寄与する旋回状の流路部１４内の洗浄液を常に清浄な状態に保つことができる。 Further, according to the first embodiment, since the opening is provided in the center of the first partition 11 and the gas-liquid two-layer flow is generated on the upper side of the swirling flow path portion 14, The fine bubbles adsorbing the water gather in the central portion of the cleaning tank 10 and rise, and when they reach the water surface of the cleaning tank 10, they move on the water flow toward the outer periphery of the upper end of the cleaning tank 10 and can quickly overflow. As a result, the cleaning liquid in the swirling channel portion 14 that contributes to cleaning can always be kept clean.

さらに、この実施の形態１によれば、旋回状の流路部１４の上側に位置する第１の仕切り１１中央の開口部を、旋回状の流路部１４の下側に位置する第２の仕切り１２中央の開口部より大きくなるように構成したので、旋回状の流路部１４の上側の洗浄液の旋回を激しく、下側の洗浄液の旋回を緩やかにすることができ、被洗浄物から剥離された油脂分の上昇および排出を促進すると共に、被洗浄物が沈降し易くなる。 Furthermore, according to the first embodiment, the opening at the center of the first partition 11 located on the upper side of the swirling flow path portion 14 is arranged on the second side located on the lower side of the swirling flow path portion 14.

Since the object is configured to sink from the outer peripheral opening 13 while turning the outer peripheral part, it is possible to avoid reattachment of the oil and fat to the object to be cleaned and to effectively separate the oil and fat and the object to be cleaned. .

さらに、この実施の形態１によれば、油水分離槽５０を少なくとも３つに分割して第１から第３分離槽５３，５４，５５を形成し、オーバーフロー槽４０から流入する洗浄液を一旦第１分離槽５３で受け入れるように構成したので、洗浄液の受け入れの際に生じる洗浄液の攪拌を第１分離槽５３内に留めることができ、第２分離槽５４では安定した油脂分の浮上分離を行うことができる。 Furthermore, according to the first embodiment, the oil / water separation tank 50 is divided into at least three to form the first to third separation tanks 53, 54, and 55, and the cleaning liquid flowing from the overflow tank 40 is temporarily supplied to the first. Since it is configured to be received by the separation tank 53, the stirring of the cleaning liquid generated when the cleaning liquid is received can be kept in the first separation tank 53, and the second separation tank 54 performs stable floating separation of fats and oils. Can do.

さらに、この実施の形態１によれば、第２分離槽５４と第３分離槽５５は槽の底部で連通するように構成しているので、第２分離槽５４では油脂分が浮上し、第２分離槽５４の底部に位置する清浄な洗浄液のみが第３分離槽５５へ流出するので、洗浄槽１０に清浄な洗浄液を循環させることができる。 Furthermore, according to the first embodiment, since the second separation tank 54 and the third separation tank 55 are configured to communicate with each other at the bottom of the tank, the oil and fat components float in the second separation tank 54, Since only the clean cleaning liquid located at the bottom of the two separation tanks 54 flows out to the third separation tank 55, the clean cleaning liquid can be circulated in the cleaning tank 10.

さらに、この実施の形態１によれば、洗浄槽１０外部で被洗浄物と洗浄液を混合する混合槽３０と、当該混合槽３０と洗浄槽１０を接続する被洗浄物投入管３２の洗浄槽１０側開口部付近に負圧発生手段３３を設けて、被洗浄物と洗浄液の混合体を洗浄槽１０内に吸入するように構成したので、特別な投入機構を用いることなく被洗浄物を洗浄槽１０内の旋回状の流路部１４へ投入することができる。 Furthermore, according to the first embodiment, the mixing tank 30 that mixes the object to be cleaned and the cleaning liquid outside the cleaning tank 10, and the cleaning tank 10 of the cleaning object input pipe 32 that connects the mixing tank 30 and the cleaning tank 10.
