Description

本発明は、液体サイクロンに関し、特に、遠心分離された後の清浄液からの発泡を抑制することのできる液体サイクロンに関するものである。   The present invention relates to a liquid cyclone, and more particularly, to a liquid cyclone capable of suppressing foaming from a cleaning liquid after being centrifuged.

従来、清浄液からの発泡を抑制することを目的とした液体サイクロン１０としては、図６に示すように、円筒部２ａと該円筒部２ａの下方に向けて漸次縮径する円錐部２ｂとからなる本体２と、前記円筒部２ａに連接した処理液導入口２ｃと、円錐部２ｂ下方を開口してなる異物排出口２ｄと、清浄液を一時貯留する上部ケース３と、前記本体２と同心で、本体２上方に配設した上部ケース３に繋がる出口管４とからなり、前記出口管４の上端に、周部に多数の孔を形成した気液分離管９を連設する液体サイクロンが提案されている（例えば、特許文献１、２参照）。   Conventionally, as shown in FIG. 6, the liquid cyclone 10 intended to suppress foaming from the cleaning liquid includes a cylindrical portion 2 a and a conical portion 2 b that gradually decreases in diameter toward the lower side of the cylindrical portion 2 a. A main body 2, a treatment liquid inlet 2 c connected to the cylindrical portion 2 a, a foreign matter discharge port 2 d opened below the conical portion 2 b, an upper case 3 for temporarily storing a cleaning liquid, and a concentricity with the main body 2. And a liquid cyclone having an outlet pipe 4 connected to the upper case 3 disposed above the main body 2, and a gas-liquid separation pipe 9 having a large number of holes formed in the periphery at the upper end of the outlet pipe 4. It has been proposed (see, for example, Patent Documents 1 and 2).

この液体サイクロン１０は、工作機械などで使用され、キリコや金属粉など（以下、「異物」という。）を含む研削液や切削液など（以下、「処理液」という。）を、円筒部２ａの接線方向に配設される処理液導入口２ｃから所定の流速で圧送し、旋回流を生じさせ、遠心力によって異物を本体２の下方に開口した異物排出口２ｄから排出するとともに、異物の取り除かれた清浄液を出口管４を介し上部ケース３に流入させる。
この際、下部の異物排出口２ｄから空気の吸込みを伴い、旋回流中心部に空気芯ができる。空気芯をとりまく清浄液は、旋回しながら上昇し、出口管４を経て気液分離管９に至るものである。 The liquid cyclone 10 is used in a machine tool or the like, and a cylindrical fluid 2a is used for grinding fluid or cutting fluid (hereinafter referred to as “treatment fluid”) containing silicon or metal powder (hereinafter referred to as “foreign matter”). Is pumped at a predetermined flow rate from the processing liquid inlet 2c arranged in the tangential direction of the nozzle, and a swirling flow is generated. Foreign matter is discharged from the foreign matter outlet 2d opened below the main body 2 by centrifugal force. The removed cleaning liquid is caused to flow into the upper case 3 through the outlet pipe 4.
At this time, air is sucked from the lower foreign matter outlet 2d, and an air core is formed at the center of the swirl flow. The cleaning liquid surrounding the air core rises while swirling, and reaches the gas-liquid separation pipe 9 through the outlet pipe 4.

しかし、上昇する清浄液の旋回流は、気液分離管９の下部から上部にかけてメッシュ孔を通って半径方向への噴出流となり、下部が強く、上部程弱くなるので図中矢印のように上部ケース３の底面→側壁面→気液分離管９に向かう回転流となり、上部ケース３内に放出された気液分離後の空気が図６のＡ部で清浄液に取り込まれてしまい、また、気液分離管９中を旋回上昇する過程でも微細気泡は、清浄液とともにメッシュ孔から排出されることによって清浄処理液から発泡するという欠点があった。
特開２００３−２１０９０８号公報 特開２００５−７２１２号公報 However, the swirling flow of the rising cleaning liquid becomes a radial flow through the mesh hole from the lower part to the upper part of the gas-liquid separation pipe 9, and the lower part is stronger and the upper part becomes weaker. It becomes a rotational flow toward the bottom surface → side wall surface → gas-liquid separation pipe 9 of the case 3, and the air after the gas-liquid separation discharged into the upper case 3 is taken into the cleaning liquid in part A of FIG. Even in the process of swirling and rising in the gas-liquid separation tube 9, there is a drawback that the fine bubbles are foamed from the cleaning treatment liquid by being discharged from the mesh holes together with the cleaning liquid.
JP 2003-210908 A Japanese Patent Laid-Open No. 2005-7212

本発明は、上記従来の液体サイクロンの有する問題点に鑑み、清浄液への気泡の混入を防止することができる液体サイクロンを提供することを目的とする。   An object of the present invention is to provide a liquid cyclone capable of preventing air bubbles from being mixed into a cleaning liquid in view of the problems of the conventional liquid cyclone.

上記目的を達成するため、本発明の液体サイクロンは、円筒部と該円筒部の下方から漸次縮径する円錐部とからなる本体と、前記円筒部に連接した処理液導入口と、円錐部下方を開口してなる異物排出口と、清浄液を一時貯留する上部ケースと、前記本体と同心で、本体上方に配設した上部ケースに繋がる出口管とからなる液体サイクロンにおいて、前記出口管内周部に隙間をあけて、処理液導入口から導入される処理液によって生じる旋回流の中心部に発生する空気芯よりも大径で、かつ、周面をメッシュ状とした筒体を上部ケースから挿入したことを特徴とする。 In order to achieve the above object, a liquid cyclone according to the present invention comprises a main body comprising a cylindrical portion and a conical portion that gradually decreases in diameter from below the cylindrical portion, a treatment liquid inlet connected to the cylindrical portion, and a lower portion of the conical portion. In the liquid cyclone comprising a foreign matter discharge port formed by opening, an upper case for temporarily storing a cleaning liquid, and an outlet pipe concentric with the main body and connected to the upper case disposed above the main body, the inner peripheral portion of the outlet pipe A cylinder with a larger diameter than the air core generated at the center of the swirling flow generated by the processing liquid introduced from the processing liquid inlet and a mesh-like peripheral surface is inserted from the upper case. It is characterized by that.

この場合において、前記筒体が、前記出口管から上部ケース内に突出する上部ケース内突出部を有し、該上部ケース内突出部を囲繞する環状体によって流出制動部を形成することができる。 In this case, the cylindrical body has an upper case protrusion that protrudes from the outlet pipe into the upper case, and the outflow braking portion can be formed by an annular body that surrounds the upper case protrusion .

また、前記流出制動部の内部に、中心に前記筒体が貫通する孔を穿設した板材からなり、前記筒体及び環状体との間に清浄液が通過する隙間を形成することによって液体の上昇を抑制する抑止板を配設することができる。 In addition, the inside of the outflow braking portion is made of a plate material having a hole through which the cylindrical body penetrates at the center, and a gap through which the cleaning liquid passes is formed between the cylindrical body and the annular body. A restraining plate that suppresses the rise can be disposed.

また、前記筒体を、出口管の下端部近傍まで延設することができる。 Moreover, the said cylinder can be extended to the lower end part vicinity of an exit pipe | tube.

また、前記筒体の断面形状を、処理液の旋回方向に対し逆方向のうずまき線形状とすることができる。   Moreover, the cross-sectional shape of the said cylinder can be made into the spiral line shape of a reverse direction with respect to the turning direction of a process liquid.

本発明の液体サイクロンによれば、出口管内周部に隙間をあけて、周面をメッシュ状とした筒体を上部ケースから挿入することにより、旋回しながら上昇してくる清浄液と空気芯のうち、内側に集中する空気芯を筒体の内部に導入し、清浄液は、メッシュ状の周面を境に筒体の外部と出口管内面で形成されるドーナツ状の空間を上昇し、上部ケース内に流入するから筒体の内外において旋回状態が維持され、空気芯を筒体内に留めることができ、清浄液内への空気の混入を有効に防止することができる。 According to the liquid cyclone of the present invention, a gap between the outlet pipe inner periphery and a cylindrical body having a mesh surface is inserted from the upper case, so that the cleaning liquid and the air wick that rises while turning are inserted. Among them, the air core concentrated inside is introduced into the inside of the cylinder, and the cleaning liquid rises through the donut-like space formed by the outside of the cylinder and the inner surface of the outlet pipe with the mesh-like peripheral surface as a boundary, is turning in and out of the cylinder is maintained from entering into the case, it is possible to keep the air-core in the cylindrical body, it is possible to effectively prevent mixing of air into the cleaning liquid in the.

また、上部ケース内に突出する上部ケース内突出部を囲繞する傘状体又は筒体からなる環状体によって流出制動部を形成することにより、上部ケースに流入する清浄液は、出口管を出る際に急激に開放されることがなく、上部ケース内の空気と拡散し、気泡が発生することを防止することができる。 Further, by forming the outflow braking portion with an annular body made of an umbrella-like body or a cylindrical body that surrounds the protruding portion in the upper case protruding into the upper case, the cleaning liquid flowing into the upper case can flow when it exits the outlet pipe. It is possible to prevent air bubbles from being generated by being diffused with the air in the upper case without being suddenly opened.

また、流出制動部の内部に、液体の上昇を抑制する抑止板を配設することにより、出口管から上部ケースの流出制動部に流入する清浄液の上方への拡散が抑制され、更に気泡の発生を有効に防止することができる。In addition, by disposing a restraining plate that suppresses the rise of the liquid inside the outflow braking unit, the upward diffusion of the cleaning liquid flowing into the outflow braking unit of the upper case from the outlet pipe is suppressed, and further the bubble Occurrence can be effectively prevented.

また、筒体を、出口管の下端部近傍まで延設することにより、上昇する空気芯と清浄液とを、出口管の入口近傍から分離することができるから、より効果的に気泡の発生を抑制することができる。   Further, by extending the cylindrical body to the vicinity of the lower end of the outlet pipe, the rising air core and the cleaning liquid can be separated from the vicinity of the inlet of the outlet pipe. Can be suppressed.

また、筒体の断面形状を、処理液の旋回方向に対し逆方向のうずまき線形状とすることにより、中心の空気芯が揺れて筒体からはみ出ることがあっても気泡は旋回して開口Ｍから再度筒体内に導入されて旋回上昇し、上部ケース内で気液分離される。   Further, by making the cross-sectional shape of the cylinder a spiral line shape opposite to the swirl direction of the processing liquid, even if the air core at the center sways and protrudes from the cylinder, the bubbles swirl and open the opening M. Then, it is again introduced into the cylinder and swirled up, and gas-liquid separation is performed in the upper case.

以下、本発明の液体サイクロンの実施の形態を、図面に基づいて説明する。尚、従来装置と同様の構造については同一の符号、一連の符号を付し説明を省略する。   Hereinafter, embodiments of the hydrocyclone of the present invention will be described with reference to the drawings. In addition, about the structure similar to a conventional apparatus, the same code | symbol and a series of code | symbol are attached | subjected, and description is abbreviate | omitted.

図１−１に、本発明の液体サイクロンの第１実施例を示す。
この液体サイクロン１は、上部ケース３に繋がる出口管４の内周部に隙間をあけて、上部ケース３から周面をメッシュ状とした筒体６を挿入するとともに、前記筒体６の上部ケース３内突出部を囲繞するメッシュ状の傘状体７によって流出制動部７ａを形成するようにしている。 FIG. 1-1 shows a first embodiment of the hydrocyclone of the present invention.
The hydrocyclone 1 includes a cylindrical body 6 whose peripheral surface is meshed from the upper case 3 with a gap in the inner peripheral portion of the outlet pipe 4 connected to the upper case 3, and the upper case of the cylindrical body 6. 3. The outflow braking portion 7a is formed by a mesh-like umbrella 7 surrounding the inner protruding portion.

筒体６は、メッシュ状（金網等）の板を筒状に巻いて構成するほか、多孔板（パンチングメタル等）やスリット等を形成した筒状体を使用しても構わない。そして、筒体６の上端を上部ケース３の上面にボルト等の固定手段で固定した、出口管４と同心となるピン６ｂに取り付け、下端を出口管４の内部に挿入するものである。
この際、筒体６は、ピン６ｂに取り付けることなく上端を開放し、上部ケース３内に傘状体７で支持させるように構成しても構わない。 The cylindrical body 6 may be configured by winding a mesh-like (metal mesh or the like) plate into a cylindrical shape, or may be a cylindrical body in which a perforated plate (such as punching metal) or a slit is formed. Then, the upper end of the cylindrical body 6 is fixed to the upper surface of the upper case 3 with a fixing means such as a bolt, and is attached to a pin 6 b concentric with the outlet pipe 4, and the lower end is inserted into the outlet pipe 4.
At this time, the cylindrical body 6 may be configured such that the upper end is opened without being attached to the pin 6 b and the umbrella 6 is supported in the upper case 3.

また、筒体６は、出口管４の内部に僅かに進入すればその挿入長さは、特に限定するものではないが、本実施例のように、出口管４の下端部近傍まで延設することが好ましい。そして、筒体６の上端には、気泡を上部ケース３の上方で開放するように空気抜孔６ａを穿孔する。筒体６の外径は、本体２内面を旋回し、異物と分離された後の清浄液と共に上昇する気泡（以下、「空気芯」という。）より大であればよい。これにより空気芯を中心にしてその外周側に位置している清浄液は、筒体６の周面と、出口管４の内面によって形成されるドーナツ状の空間４ａを旋回しながら上昇するものである。また、筒体６は、図５に示すように断面形状を処理液の旋回方向に対し逆方向のうずまき線形状としておくこともできる。この場合、中心の空気芯が揺れて筒体からはみ出ることがあっても、気泡は旋回して開口Ｍから再度筒体６内に導入されて旋回上昇し、上部ケース内で気液分離される。   Further, the insertion length of the cylindrical body 6 is not particularly limited as long as it slightly enters the inside of the outlet pipe 4, but it extends to the vicinity of the lower end portion of the outlet pipe 4 as in this embodiment. It is preferable. An air vent hole 6 a is drilled at the upper end of the cylinder 6 so as to open the bubbles above the upper case 3. The outer diameter of the cylindrical body 6 only needs to be larger than bubbles (hereinafter referred to as “air core”) that swirl on the inner surface of the main body 2 and rise together with the cleaning liquid after being separated from the foreign matter. As a result, the cleaning liquid located on the outer peripheral side with the air core as the center rises while turning around the donut-shaped space 4 a formed by the peripheral surface of the cylindrical body 6 and the inner surface of the outlet pipe 4. is there. Further, as shown in FIG. 5, the cylindrical body 6 may have a cross-sectional shape in a spiral line shape opposite to the swirl direction of the processing liquid. In this case, even if the air core at the center may sway and protrude from the cylinder, the bubbles are swirled and re-introduced into the cylinder 6 from the opening M and swirled and raised, and the gas and liquid are separated in the upper case. .

傘状体７は、上部ケース３内に突出する筒体６の周面適所から延設し、上部ケース３の下面３ａに当接するメッシュ状の板材からなり、円錐台形状に構成する。傘状体７は、筒体６と同様、メッシュ状の板を円錐台状に巻いて構成するほか、多孔板やスリット等を形成した板状体を円錐台形状に変形して使用しても構わない。傘状体７は、筒体６の周面に、接着剤や溶接等の固着手段で固着するもので、筒体６の上端を開放し、ピン６ｂに取り付けないときは、傘状体７の上部ケース３の下面３ａへの取り付け手段３ａ−１や、上部ケース３の側壁との間隔維持片３ａ−２によって傘状体７を介して筒体６が、出口管４と同心を保つように構成する。   The umbrella-like body 7 extends from an appropriate place on the circumferential surface of the cylindrical body 6 protruding into the upper case 3, is made of a mesh-like plate material that comes into contact with the lower surface 3 a of the upper case 3, and has a truncated cone shape. The umbrella-like body 7 is configured by winding a mesh-like plate in a truncated cone shape similarly to the cylindrical body 6, or a plate-like body in which a porous plate, a slit or the like is formed may be used after being transformed into a truncated cone shape. I do not care. The umbrella body 7 is fixed to the peripheral surface of the cylinder body 6 by an adhesive or welding means. When the upper end of the cylinder body 6 is opened and not attached to the pin 6b, the umbrella body 7 The cylindrical body 6 is kept concentric with the outlet pipe 4 via the umbrella-like body 7 by means of attaching means 3a-1 to the lower surface 3a of the upper case 3 and a distance maintaining piece 3a-2 with the side wall of the upper case 3. Constitute.

そして、この傘状体７によって形成する流出制動部７ａによって、上部ケース３に流入する清浄液は急激に開放されることがないので、気泡が発生することを防止することができる。   Then, the outflow braking portion 7a formed by the umbrella 7 prevents the cleaning liquid flowing into the upper case 3 from being suddenly released, so that bubbles can be prevented from being generated.

このように、本実施例においては、筒体６を囲繞する傘状体７からなる環状体によって流出制動部７ａを形成することにより気泡の発生を防止するようにしたが、気泡の発生の少ない清浄液を対象とする場合には、図１−２に示す第１変形実施例のように（他の実施例においても同様）、傘状体７からなる環状体を省略することができ、これにより、装置の構造を簡略化するとともに、メンテナンスを簡易化することができる。   As described above, in this embodiment, the outflow braking portion 7a is formed by the annular body including the umbrella body 7 surrounding the cylindrical body 6 to prevent the generation of bubbles, but the generation of bubbles is small. When the cleaning liquid is a target, an annular body made of an umbrella 7 can be omitted as in the first modified example shown in FIG. 1-2 (the same applies to other examples). As a result, the structure of the apparatus can be simplified and the maintenance can be simplified.

また、傘状体７は、図３に示す第２変形実施例のように、上板７１と側板７２からなら円筒状の筒体７０として構成しても構わない。図示の筒体７０では、上板７１、側板７２共にメッシュ状板としているが、上板７１は無孔板であっても構わない。また、筒体７０の代わりに図４に示すように上部が開放された液溜め環状体７５で流出制動部を形成するようにしてもよい。   Further, the umbrella body 7 may be configured as a cylindrical tube body 70 including the upper plate 71 and the side plate 72 as in the second modified example shown in FIG. In the illustrated cylinder 70, both the upper plate 71 and the side plate 72 are mesh plates, but the upper plate 71 may be a non-porous plate. Further, as shown in FIG. 4, the outflow braking portion may be formed by a liquid reservoir annular body 75 having an open upper portion instead of the cylindrical body 70.

上記構成において、従来例と同様に、工作機械などで使用された異物を含む処理液を、円筒部２ａの接線方向に配設される処理液導入口２ｃから所定の流速で圧送し、旋回流を生じさせ、遠心力によって異物を本体２の下方に開口した異物排出口２ｄから排出するとともに、異物の取り除かれた清浄液は、空気芯と共に、出口管４に向かって旋回しながら上昇する。この際、出口管４には、空気芯より大径の筒体６が挿入されており、筒体６中を清浄液及び空気芯が旋回しながら上昇し、また、筒体６の周面と出口管４の内面によって形成されるドーナツ状の空間４ａを清浄液が旋回しながら上昇する。出口管４を出た筒体６内外の清浄液は旋回状態が維持されているので、空気芯は筒体６内に留められつつメッシュ孔で気液分離される。
そして、大半の清浄液は、空間４ａを旋回しながら上昇し、出口管４を通過したところで上部ケース３に流入するも、傘状体７や筒体７０によって流出制動部７ａが形成されているため、清浄液は急激に開放されることがなく、気泡の発生を抑制することができる。 In the above configuration, as in the conventional example, the processing liquid containing foreign matter used in a machine tool or the like is pumped at a predetermined flow rate from the processing liquid inlet 2c disposed in the tangential direction of the cylindrical portion 2a, and the swirl flow The foreign matter is discharged from the foreign matter discharge port 2d opened below the main body 2 by centrifugal force, and the cleaning liquid from which the foreign matter has been removed rises while turning toward the outlet pipe 4 together with the air core. At this time, a cylindrical body 6 having a diameter larger than that of the air core is inserted into the outlet pipe 4, and the cleaning liquid and the air core are raised while swirling in the cylindrical body 6. The cleaning liquid ascends in a donut-shaped space 4a formed by the inner surface of the outlet pipe 4 while swirling. Since the swirling state of the cleaning liquid inside and outside the cylindrical body 6 exiting the outlet pipe 4 is maintained, the air core is gas-liquid separated at the mesh hole while being retained in the cylindrical body 6.
Most of the cleaning liquid rises while swirling the space 4 a and flows into the upper case 3 after passing through the outlet pipe 4, but the outflow braking portion 7 a is formed by the umbrella body 7 and the cylindrical body 70. Therefore, the cleaning liquid is not suddenly opened, and generation of bubbles can be suppressed.

図２に、本発明の液体サイクロンの第２実施例を示す。
この液体サイクロン１は、実施例１と同様の構成からなり、更に、流出制動部７ａの内部に、出口管４から旋回流となって流出制動部７ａに流入する清浄液の上昇を抑制する抑止板８を配設するようにしている。 FIG. 2 shows a second embodiment of the hydrocyclone of the present invention.
The hydrocyclone 1 has the same configuration as that of the first embodiment, and further suppresses the rise of the cleaning liquid flowing into the outflow braking unit 7a as a swirling flow from the outlet pipe 4 inside the outflow braking unit 7a. A plate 8 is arranged.

この抑止板８の形状、材質は、特に限定されるものではないが、無孔の板材を使用するほか、筒体６や傘状体７と同様にメッシュ状の板や、多孔板やスリット等を形成した方形板、円形板を使用しても構わない。そして、図２（ｂ）に示すように、中心に筒体６が通過する孔８ａを穿孔した正方形の板で構成し、傘状体７の内周面適所に固定して構成するほか、上部ケース３の下面３ａに少し間隔をあけて置くだけでもよい。この場合は、上昇する清浄液の上方への流速によって抑止板８は浮上し、抑止板８の対角となる角部８ｂ、８ｂが傘状体７の内周面に当接したところで停止し、清浄液の上昇を抑制する。   The shape and material of the restraining plate 8 are not particularly limited, but a non-porous plate material is used, and a mesh plate, a perforated plate, a slit, etc. You may use the square board and circular board which formed this. And as shown in FIG.2 (b), it comprises with the square board which perforated the hole 8a which the cylinder 6 passes in the center, and it fixes to the inner peripheral surface suitable place of the umbrella-shaped body 7, and is comprised, It may be simply placed on the lower surface 3a of the case 3 with a little space. In this case, the restraint plate 8 is lifted by the upward flow rate of the rising cleaning liquid, and stops when the corners 8b and 8b which are opposite to the restraint plate 8 come into contact with the inner peripheral surface of the umbrella 7. , Suppress the rise of cleaning liquid.

また、抑止板８は、図３に示す第２変形実施例のように、環状体を筒体７０で構成するときは、側板７２の内周面適所に固定するほか、抑止板８の対角となる角部８ｂ、８ｂが当接する輪状の浮上停止板７３を側板７２の内周面適所に配設するようにしてもよい。
これにより、流出制動部７ａ内での清浄液は、まず、流出制動部７ａの抑止板８より下方の下部室７ｂでその大半が抑止板８の下面にぶつかり、その勢いを低減され、抑止板８の孔８ａと筒体６との隙間８ｃ、及び抑止板８の各辺と傘状体７の内周面との間で形成される円弧状の隙間８ｄから、抑止板８の上方に形成される上部室７ｃに流入する。
この際、抑止板８の材質をメッシュ状の板や、多孔板やスリット等を形成した場合は、当該孔部分からも清浄液は上部室７ｃに流入する。 In addition, when the annular body is constituted by the cylindrical body 70 as in the second modified example shown in FIG. 3, the restraining plate 8 is fixed to a suitable position on the inner peripheral surface of the side plate 72, and the diagonal of the restraining plate 8. A ring-shaped levitation stop plate 73 with which the corner portions 8b and 8b come into contact with each other may be disposed at a suitable place on the inner peripheral surface of the side plate 72.
As a result, most of the cleaning liquid in the outflow braking unit 7a first collides with the lower surface of the deterrence plate 8 in the lower chamber 7b below the deterrence plate 8 of the outflow braking unit 7a. 8 is formed above the suppression plate 8 from the clearance 8c between the hole 8a and the cylinder 6 and the arc-shaped clearance 8d formed between each side of the suppression plate 8 and the inner peripheral surface of the umbrella-shaped body 7. Flow into the upper chamber 7c.
At this time, if the material of the suppression plate 8 is a mesh plate, a perforated plate, a slit, or the like, the cleaning liquid also flows into the upper chamber 7c from the hole portion.

このように、流出制動部７ａの内部に、抑止板８を配設するときは、清浄液が、出口管４から上部ケース３に開放された後、流出制動部７ａ内で、更にその上昇の勢いを抑えることができるから、清浄液内への気泡の混入を効率よく防止することができる。   Thus, when the restraining plate 8 is disposed inside the outflow braking portion 7a, after the cleaning liquid is released from the outlet pipe 4 to the upper case 3, the rise is further increased in the outflow braking portion 7a. Since the momentum can be suppressed, mixing of bubbles into the cleaning liquid can be effectively prevented.

以上、本発明の液体サイクロンについて、複数の実施例に基づいて説明したが、本発明は上記実施例に記載した構成に限定されるものではなく、その趣旨を逸脱しない範囲において適宜その構成を変更することができるものである。   As mentioned above, although the liquid cyclone of the present invention has been described based on a plurality of embodiments, the present invention is not limited to the configurations described in the above embodiments, and the configurations are appropriately changed without departing from the spirit thereof. Is something that can be done.

本発明の液体サイクロンは、清浄液への気泡の混入を防止することができることから、新規の液体サイクロンに用いることができるほか、例えば、既設の液体サイクロンにも、筒体と傘状体を取り付ける改造することによって用いることができる。   Since the liquid cyclone of the present invention can prevent bubbles from being mixed into the cleaning liquid, it can be used for a novel liquid cyclone. For example, a cylindrical body and an umbrella-like body are attached to an existing liquid cyclone. It can be used by remodeling.
