FIG. FIG. 1 is a cross-sectional view of a filtering device 1 of the present invention. FIG. 2 is a view showing a section 2-2 of FIG. 1, which is a view showing a section of the filtering device 1 in a decompressed state. FIG. 3 is a cross-sectional view of the filtering device 1 in a decompression stop state. FIG. 4 is a view showing section 4-4 of FIG. 5A to 5C are diagrams showing a mechanism for blocking the exhaust path so that filtered liquid does not flow into the pump in the filtering device 1 of the present invention.

まず、図１に示すように、濾過装置１は、ポンプユニット１１と、濾過後液リザーバ１２と、濾過前液リザーバ１３とを備えている。ここで、本明細書では、濾過を行う液体を「濾過前液」とよび、その濾過前液を濾過した液体を「濾過後液」とよぶ。濾過前液リザーバ１３は濾過後液リザーバ１２の上側に位置するように濾過後液リザーバ１２と密閉接続が可能であって、濾過後液リザーバ１２はポンプユニット１１の上側に位置するようにポンプユニット１１と密閉接続が可能である。ポンプユニット１１と、濾過後液リザーバ１２と、濾過前液リザーバ１３とのそれぞれは、下からポンプユニット１１、濾過後液リザーバ１２、濾過前液リザーバ１３の順に鉛直方向に積み上げ可能な、断面が同一形状の柱状体である。ポンプユニット１１と、濾過後液リザーバ１２と、濾過前液リザーバ１３とのそれぞれの断面は、四角形を代表とする多角形であってもよい。これらを鉛直方向に積み上げると、多角柱形状となる。特に、代表的で好ましい例では、断面は円形であり、この場合では、ポンプユニット１１と、濾過後液リザーバ１２と、濾過前液リザーバ１３とのそれぞれは同心の円柱状であり、これらを鉛直方向に積み上げると、濾過装置１の全体的形態も円柱状となる。この明細書では、これを例として、以下説明を行う。また、ここで、ポンプユニット１１、濾過後液リザーバ１２、濾過前液リザーバ１３の順に鉛直方向に積み上げられた状態におけるこれらの円柱形状の中心を濾過装置１の中心軸ＣＬとする。中心軸ＣＬが延在する方向は、濾過後液リザーバ１２、濾過前液リザーバ１３の深さ方向となる。 First, as shown in FIG. 1 , the filtration device 1 includes a pump unit 11 , a post-filtration liquid reservoir 12 , and a pre-filtration liquid reservoir 13 . Here, in this specification, the liquid to be filtered is called "pre-filtration liquid", and the liquid obtained by filtering the pre-filtration liquid is called "post-filtration liquid". The pre-filtration reservoir 13 can be hermetically connected to the post-filtration reservoir 12 so as to be positioned above the post-filtration reservoir 12 , and the post-filtration reservoir 12 is positioned above the pump unit 11 . 11 and a hermetic connection are possible. Each of the pump unit 11, the post-filtration reservoir 12, and the pre-filtration reservoir 13 has a cross section that can be vertically stacked in the order of the pump unit 11, the post-filtration reservoir 12, and the pre-filtration reservoir 13 from the bottom. They are columnar bodies of the same shape. The cross section of each of the pump unit 11, the post-filtration reservoir 12, and the pre-filtration reservoir 13 may be polygonal, typically quadrangular. When these are stacked vertically, they form a polygonal column. In particular, in a typical and preferred example, the cross section is circular, and in this case, the pump unit 11, the post-filtration reservoir 12, and the pre-filtration reservoir 13 are concentric cylinders. When stacked in the direction, the overall shape of the filtering device 1 is also cylindrical. In this specification, this is taken as an example for the following description. Here, the central axis CL of the filter device 1 is defined as the center of the cylindrical shape of the pump unit 11, the post-filtration reservoir 12, and the pre-filtration reservoir 13 stacked in this order in the vertical direction. The direction in which the central axis CL extends is the depth direction of the post-filtration liquid reservoir 12 and the pre-filtration liquid reservoir 13 .

ポンプユニット１１は、断面が所定の半径を有する円形である外形を有し、内部が中空の円筒形状のポンプハウジング１１１からなる。ポンプハウジング１１１の内部には、真空ポンプなどの脱気用のポンプ１１２が内蔵されている。ポンプハウジング１１１の上側にはポンプハウジング１１１の上面から隆起するように形成される突起１１３を備えていて、突起１１３の頂上部にはポンプ１１２の吸気ラインへと連通する吸気口１１３ａを備えていて、ポンプ１１２により、吸気口１１３ａから空気を吸い込んで外部環境に排出する。ポンプハウジング１１１の外周はポンプハウジング１１１の上面から円筒状に壁面２１ａが立ち上がっており、この壁面２１ａによりポンプハウジング１１１の上面には一定の容積の空間が形成されている。ポンプハウジング１１１の上面には、例えばほぼ中央部に、隆起するように形成される突起１１３を有しているので、その空間は突起１１３の根本の周りに形成され、その空間は、ポンプハウジング１１１の上面を底部とする液溜りとしてのトラップ１１４として機能する。すなわち、排気部１２１ｂに導かれた気体に含まれるミスト状に細かい液滴などの液体成分は、その気体が吸気口１１３ａに引き込まれるとともに、突起１１３に衝突して液化する。液体となって突起１１３から流れだした液体は液溜りであるトラップ１１４に流れ込むようにして、脱気用のポンプ１１２内に液体成分が侵入することを防いでいる。ポンプハウジング１１１の壁面１１１ａの端部にはフランジ１１５３を有している。 The pump unit 11 includes a cylindrical pump housing 111 having a circular cross section with a predetermined radius and a hollow inside. A deaeration pump 112 such as a vacuum pump is built in the pump housing 111 . The upper side of the pump housing 111 is provided with a projection 113 formed so as to protrude from the upper surface of the pump housing 111, and the top of the projection 113 is provided with an intake port 113a communicating with the intake line of the pump 112. , the pump 112 draws in air from the intake port 113a and discharges it to the external environment. A cylindrical wall surface 21a rises from the upper surface of the pump housing 111 on the outer periphery of the pump housing 111, and the wall surface 21a forms a space of a certain volume on the upper surface of the pump housing 111. As shown in FIG. Since the upper surface of the pump housing 111 has a protrusion 113 formed to protrude, for example, at approximately the center, the space is formed around the root of the protrusion 113, and the space is the same as that of the pump housing 111. It functions as a trap 114 as a liquid pool whose bottom is the upper surface of the . That is, liquid components such as mist-like fine droplets contained in the gas guided to the exhaust portion 121b are drawn into the air inlet 113a and collide with the projections 113 to be liquefied. The liquid that flows out from the projection 113 as a liquid flows into a trap 114 that is a liquid reservoir, thereby preventing the liquid component from entering the degassing pump 112 . A flange 1153 is provided at the end of the wall surface 111a of the pump housing 111 .

濾過後液リザーバ１２は、代表的には、断面がポンプユニット１１の断面の径と同一の径である円形である外形を有し、内部が中空の円筒形状である濾過後液リザーバハウジング１２１で形成される。濾過後液リザーバハウジング１２１の両端にはそれぞれは開口を有していて、濾過前液リザーバ１３と接続する側の一端にはフランジ１２５３を、反対の端部であるポンプユニット１１と接続する側の端部にはフランジ１２５１を有している。濾過後液リザーバ１２は、ポンプハウジング１１１の上側に位置するように、濾過後液リザーバ１２のフランジ１２５１とポンプハウジング１１１のフランジ１１５３とが突きあって接触可能である。また、濾過後液リザーバ１２のフランジ１２５１とポンプハウジング１１１のフランジ１１５３の断面は、少なくとも外径寸法が同じであり、さらには共通の形状である。濾過後液リザーバ１２のフランジ１２５１とポンプハウジング１１１のフランジ１１５３は、それぞれの本体からフランジの径分だけ外側に突出している形状である。そして、ここで、この径を内径としてフランジ１２５１とフランジ１１５３との両方を包み込むような袋状の環状のシール部材５を用意する。シール部材５が、濾過後液リザーバ１２とポンプハウジング１１１との両方のフランジを包み込むように挟んで、濾過後液リザーバハウジング１２１がポンプハウジング１１１の上側に位置するように、ポンプハウジング１１１と濾過後液リザーバハウジング１２１との間で密閉した接続が可能である。シール部材５の材料は、たとえばゴムなどの樹脂である。すなわち、ポンプユニット１１のポンプハウジング１１１と濾過後液リザーバ１２との密閉接続は、ポンプユニット１１のポンプハウジング１１１の端面と濾過後液リザーバ１２との端面とを包み込むことが可能な環状のシール部材５により行われる。 The filtered liquid reservoir 12 typically has a circular outer shape whose cross section has the same diameter as the cross section of the pump unit 11, and a filtered liquid reservoir housing 121 having a hollow cylindrical shape inside. It is formed. Both ends of the post-filtration liquid reservoir housing 121 have openings, and a flange 1253 is provided at one end connected to the pre-filtration liquid reservoir 13, and a flange 1253 is provided at the opposite end, which is the side connected to the pump unit 11. It has a flange 1251 at the end. A flange 1251 of the filtered liquid reservoir 12 and a flange 1153 of the pump housing 111 abut each other so that the filtered liquid reservoir 12 is located above the pump housing 111 so that the flanges 1251 and 1153 can contact each other. In addition, the cross sections of the flange 1251 of the filtered liquid reservoir 12 and the flange 1153 of the pump housing 111 have at least the same outer diameter and also have a common shape. The flange 1251 of the filtered liquid reservoir 12 and the flange 1153 of the pump housing 111 are shaped to protrude outward from the respective main bodies by the diameter of the flanges. Then, a bag-shaped ring-shaped sealing member 5 having this diameter as an inner diameter and enclosing both the flange 1251 and the flange 1153 is prepared. The seal member 5 sandwiches the flanges of both the filtered liquid reservoir 12 and the pump housing 111 so that the filtered liquid reservoir housing 121 is located above the pump housing 111 . A sealed connection is possible with the liquid reservoir housing 121 . The material of the sealing member 5 is, for example, resin such as rubber. That is, the sealing connection between the pump housing 111 of the pump unit 11 and the filtered liquid reservoir 12 is an annular sealing member capable of enclosing the end surface of the pump housing 111 of the pump unit 11 and the end surface of the filtered liquid reservoir 12. 5.

濾過後液リザーバ１２は、その内部の中空の部分に隔絶部材１２２が配置されている。隔絶部材１２２は、濾過後液リザーバ１２の内面の円周の全面と接続して、液体の貯蔵を行う貯蔵部１２１ａと、ポンプハウジング１１１の吸気口１１３ａと連通する排気部１２１ｂとを、濾過後液リザーバ１２の底部に画定している。排気部１２１ｂにおいて隔絶部材１２２と反対側は開口を形成してポンプユニット１１の上面側が排気部１２１ｂ内に露出するようになっている。貯蔵部１２１ａと排気部１２１ｂとは連通しない。隔絶部材１２２は、濾過後液リザーバ１２の円筒形状の中心軸に対して垂直でもよいし、図１に示すように傾いていてもよい。濾過後液リザーバ１２とポンプハウジング１１１とがシール部材５により密閉接続した際には、隔絶部材１２２とポンプハウジング１１１（ポンプハウジング１１１の上面(トラップ１１４)）と濾過後液リザーバ１２の濾過後液リザーバハウジング１２１の内面とポンプハウジング１１１の内面によって囲まれる空間が排気のための容積をもった空間として排気部１２１ｂが形成される。 The post-filtration liquid reservoir 12 has an isolation member 122 arranged in its inner hollow portion. The isolation member 122 is connected to the entire circumference of the inner surface of the post-filtration liquid reservoir 12, and separates a storage portion 121a for storing the liquid and an exhaust portion 121b communicating with the suction port 113a of the pump housing 111 for post-filtration liquid storage. It is defined at the bottom of the liquid reservoir 12 . An opening is formed on the opposite side of the isolation member 122 in the exhaust portion 121b so that the upper surface side of the pump unit 11 is exposed in the exhaust portion 121b. Storage portion 121a and exhaust portion 121b are not communicated with each other. The isolation member 122 may be perpendicular to the central axis of the cylindrical shape of the filtered liquid reservoir 12, or may be angled as shown in FIG. When the filtered liquid reservoir 12 and the pump housing 111 are hermetically connected by the seal member 5 , the isolation member 122 and the pump housing 111 (upper surface (trap 114 ) of the pump housing 111 ) and the filtered liquid in the filtered liquid reservoir 12 A space surrounded by the inner surface of the reservoir housing 121 and the inner surface of the pump housing 111 forms an exhaust portion 121b as a space having a volume for exhaust.

At least one of the ends of the pre-filtrate reservoir housing 131 of the pre-filtrate reservoir 13 has a flange 1351 . A corresponding flange 1253 is also provided on the end 31a side of the filtered liquid reservoir housing 121 of the filtered liquid reservoir 12 . The flange 1351 of the pre-filtration liquid reservoir housing 131 of the pre-filtration liquid reservoir 13 and the flange 1253 of the post-filtration liquid reservoir housing 121 of the post-filtration liquid reservoir 12 have at least the same outer diameter, and also have a common shape. be. The pre-filtered liquid reservoir 13 can contact the flange 1253 of the filtered liquid reservoir 12 and the flange 1351 of the pre-filtered liquid reservoir housing 131 so as to be located above the filtered liquid reservoir housing 121 . The cross sections of the flange 1253 of the filtered liquid reservoir housing 121 and the flange 1351 of the unfiltered liquid reservoir housing 131 have the same diameter and concentric annular shape. A flange 1253 on the end side of the filtered liquid reservoir housing 121 and a flange 1351 on the unfiltered liquid reservoir housing 131 are shaped to protrude outward from the respective bodies by the width of the respective flanges. Then, a bag-shaped ring-shaped sealing member 5 having this diameter as an inner diameter and enclosing the flange 1253 and the flange 1351 is prepared. The sealing member 5 is sandwiched so as to wrap the flanges of both the post-filtration liquid reservoir housing 121 and the pre-filtration liquid reservoir housing 131 so that the pre-filtration liquid reservoir housing 131 is positioned above the post-filtration liquid reservoir housing 121 . , a sealed connection is possible between the post-filtration reservoir housing 121 and the pre-filtration reservoir housing 131 . A reservoir 121a defined by the isolation member 122 of the filtered fluid reservoir 12, the inner surface of the filtered fluid reservoir 12 and the bottom 131a of the unfiltered fluid reservoir 13 is capable of storing filtered fluid therein. A discharge port 132 for discharging the filtrate to the filtered liquid reservoir 12 protrudes from the bottom portion 131 a of the unfiltered liquid reservoir 13 so as to be positioned in the filtered liquid storage section 121 a inside the filtered liquid reservoir 12 . The discharge port 132 is provided with a discharge valve 133 that reduces the pressure of the filtered liquid reservoir 12 and discharges the filtered filtered liquid when the pressure drops below a predetermined pressure. Hereinafter, a state in which the pre-filtration liquid reservoir 13 and the post-filtration liquid reservoir 12 are hermetically connected, and a state in which the post-filtration liquid reservoir 12 and the pump unit 11 are hermetically connected will be described. The material of the sealing member 5 is, for example, resin such as rubber. That is, the sealed connection between the filtered liquid reservoir 12 and the unfiltered liquid reservoir 13 is performed by the annular sealing member 5 capable of wrapping the end surfaces of the filtered liquid reservoir 12 and the unfiltered liquid reservoir 13 .

濾過後液リザーバ１２は、貯蔵部１２１ａの壁面に、貯蔵部１２１ａから外部に貫通する連通孔である貯蔵部脱気口１２ａを、また排気部１２１ｂの壁面に、排気部１２１ｂから外部に貫通する連通孔である排気口１２ｂと、を有している。貯蔵部脱気口１２ａは濾過前液リザーバ１３に近い側の濾過後液リザーバ１２の端部近傍に配置され、排気口１２ｂは、濾過前液リザーバ１３から遠い側（ポンプユニット１１に近い側）の濾過後液リザーバ１２の端部の側に配置される。貯蔵部脱気口１２ａと、排気口１２ｂとを、排気管路７により接続することで、貯蔵部１２１ａから排気部１２１ｂとを経由してポンプ１１２に至る貯蔵部１２１ａ内の空気を排気する経路が画定される。この状態で、ポンプ１１２が稼動すると吸気口１１３ａから排気部１２１ｂがまず減圧され、排気管路７を経由して濾過後液リザーバ１２の貯蔵部１２１ａが続いて減圧されると、大気開放される濾過前液リザーバ１３の濾過前液が減圧された濾過後液リザーバ１２に向かって差圧により引き込まれて、フィルタ１３４を通過して濾過されて濾過後液リザーバ１２の貯蔵部１２１ａに至る。 The post-filtration liquid reservoir 12 has a storage section degassing port 12a, which is a communication hole penetrating from the storage section 121a to the outside, through the wall surface of the storage section 121a, and penetrates through the wall surface of the exhaust section 121b to the outside from the exhaust section 121b. and an exhaust port 12b, which is a communication hole. The storage part degassing port 12a is arranged near the end of the post-filtration liquid reservoir 12 on the side closer to the pre-filtration liquid reservoir 13, and the exhaust port 12b is arranged on the far side from the pre-filtration liquid reservoir 13 (the side close to the pump unit 11). is located on the side of the end of the filtered liquid reservoir 12 . By connecting the storage part degassing port 12a and the exhaust port 12b by the exhaust pipe line 7, a path for exhausting the air in the storage part 121a from the storage part 121a to the pump 112 via the exhaust part 121b. is defined. In this state, when the pump 112 is operated, the pressure is first reduced from the intake port 113a to the exhaust portion 121b, and when the pressure is subsequently reduced in the storage portion 121a of the filtered liquid reservoir 12 via the exhaust pipe 7, the pressure is released to the atmosphere. The pre-filtration liquid in the pre-filtration liquid reservoir 13 is drawn toward the decompressed post-filtration liquid reservoir 12 by the differential pressure, passes through the filter 134 and is filtered, and reaches the reservoir 121 a of the post-filtration liquid reservoir 12 .

濾過後液リザーバ１２は取手６を配置して、排気管路７はこの取手６の内部に穿設される。取手６は、ユーザが、濾過後液リザーバ１２を容易に運搬できるように配置される取手である。濾過のプロセスの実行および停止はポンプ１１２の動作およびその停止により管理することができるが、たとえば、貯蔵部１２１ａと排気部１２１ｂとを隔絶することにより濾過のプロセスの実行および停止を行うこともできる。たとえば、図２および図３のように、濾過後液リザーバ１２の深さ方向である中心軸方向に沿って取手６を摺動可能に（移動可能に）取り付ける。このとき、図２の状態（第一状態）では、排気管路７と貯蔵部脱気口１２ａとが接続することにより、貯蔵部１２１ａと排気管路７とが連通する。この位置において、排気管路７と排気口１２ｂとが合致するように設定され、排気管路７と排気口１２ｂとが接続して、排気管路７と排気部１２１ｂとが連通するようになっている。この第一状態では、まず排気部１２１ｂが減圧され、その減圧により貯蔵部脱気口１２ａと連通する排気管路７が続いて減圧されて、最終的に貯蔵部１２１ａの内部が減圧される減圧状態である。貯蔵部１２１ａ内の空気は、貯蔵部１２１ａから排気管路７を通って排気部１２１ｂを介してポンプ１１２により排気される。 The filtered liquid reservoir 12 is provided with a handle 6 , and the exhaust line 7 is drilled inside the handle 6 . The handle 6 is a handle arranged to allow the user to easily carry the post-filtrate reservoir 12 . Execution and stopping of the filtration process can be managed by operating and stopping the pump 112, but it is also possible to perform and stop the filtration process by, for example, isolating the storage section 121a and the exhaust section 121b. . For example, as shown in FIGS. 2 and 3, the handle 6 is attached slidably (movably) along the central axis direction, which is the depth direction of the filtered liquid reservoir 12 . At this time, in the state shown in FIG. 2 (first state), the storage section 121a and the exhaust line 7 are communicated by connecting the exhaust line 7 and the storage section degassing port 12a. At this position, the exhaust pipe line 7 and the exhaust port 12b are set so as to match each other, the exhaust pipe line 7 and the exhaust port 12b are connected, and the exhaust pipe line 7 and the exhaust portion 121b are communicated with each other. ing. In this first state, first, the exhaust part 121b is depressurized, and the exhaust pipe line 7 communicating with the storage part degassing port 12a is depressurized by the depressurization, and finally the inside of the storage part 121a is depressurized. state. The air in the storage portion 121a is exhausted by the pump 112 from the storage portion 121a through the exhaust pipe line 7 and the exhaust portion 121b.

続いて、図３の状態（第二状態）のように、取手６を濾過後液リザーバ１２の中心軸方向である深さ方向に沿って、摺動により移動させる。第一状態では、貯蔵部脱気口１２ａと排気管路７とが合致していたところ、この移動により、第二状態においては、貯蔵部脱気口１２ａと排気管路７との位置と、排気管路７と排気部１２１ｂとの位置との、少なくとも一方が合致しないように設定される。図３では、第二状態としては、貯蔵部脱気口１２ａと排気管路７との位置と、または排気管路７と排気部１２１ｂとの位置との両方が合致しないように示しているが、少なくとも一方が合致しない状態としておく。このように、濾過後液リザーバ１２の取手６を濾過後液リザーバ１２に対して移動可能とすることで、簡易に、貯蔵部脱気口１２ａと排気口１２ｂとが排気管路７を介して連通しないで第一状態を解除する非連通状態を作り出すことができる。この際には、濾過後液リザーバ１２の貯蔵部１２１ａは、ポンプ１１２によっては減圧されない減圧停止状態すなわち非減圧状態（第二状態）となる。このように、本願発明においては、取手６を濾過後液リザーバ１２の運搬のみならず、濾過装置１の減圧と減圧停止との間を切り替えるスイッチとして機能させることもできる。連通状態においては、排気管路７と貯蔵部脱気口１２ａとの間に、また排気管路７と排気口１２ｂとの間に、シール部材を配置して、密閉することが可能なようにしておくことが好ましい。 Subsequently, as in the state (second state) of FIG. 3 , the handle 6 is slidably moved along the depth direction, which is the direction of the center axis of the filtered liquid reservoir 12 . In the first state, the storage portion degassing port 12a and the exhaust pipe line 7 were aligned, but due to this movement, in the second state, the positions of the storage portion degassing port 12a and the exhaust pipe line 7, and At least one of the position of the exhaust pipe line 7 and the position of the exhaust portion 121b is set so as not to match. In FIG. 3, as the second state, both the positions of the storage section degassing port 12a and the exhaust pipe line 7 and the positions of the exhaust pipe line 7 and the exhaust section 121b do not match. , at least one of which does not match. By making the handle 6 of the filtered liquid reservoir 12 movable relative to the filtered liquid reservoir 12 in this manner, the storage section degassing port 12 a and the exhaust port 12 b can be easily connected via the exhaust pipe line 7 . A non-communication state can be created that releases the first state without communication. At this time, the reservoir 121 a of the filtered liquid reservoir 12 is in a decompression stop state (second state) in which the pressure is not decompressed by the pump 112 . Thus, in the present invention, the handle 6 can be used not only to carry the filtered liquid reservoir 12 but also to function as a switch for switching between decompression and decompression stop of the filtering device 1 . In the communicating state, a sealing member is arranged between the exhaust line 7 and the storage vent port 12a and between the exhaust line 7 and the exhaust port 12b to enable sealing. It is preferable to keep

取手６の上記移動は、この実施例のように、たとえば、ポンプユニット１１のポンプハウジング１１１と、濾過後液リザーバ１２の濾過後液リザーバハウジング１２１と、濾過前液リザーバ１３の濾過前液リザーバハウジング１３１とが組み合った際の中心軸ＣＬの方向にそって摺動するような形態（図１と図３）とすることが可能である。ただし、この移動の形態には限られず、たとえば、上記中心軸ＣＬと直交する軸周りに回転するような形態でもよい。排気管路７と貯蔵部脱気口１２ａ，３ｂとが連通する連通状態、すなわち排気状態（第一状態）と、連通しない非連通状態、すなわち非排気状態（第二状態）とが、取手６の移動により喚起される限り、取手６の移動の方向、移動の形態は限定されない。 The movement of the handle 6 is, for example, the pump housing 111 of the pump unit 11, the post-filtration reservoir housing 121 of the post-filtration reservoir 12, and the pre-filtration reservoir housing of the pre-filtration reservoir 13, as in this embodiment. 131 can slide along the direction of the central axis CL (FIGS. 1 and 3). However, it is not limited to this form of movement, and may be, for example, a form of rotation around an axis perpendicular to the central axis CL. The handle 6 has a communication state in which the exhaust pipe line 7 and the storage unit vents 12a and 3b communicate, that is, an exhaust state (first state), and a non-communication state, that is, a non-exhaust state (second state) in which they do not communicate. As long as it is aroused by the movement of the handle 6, the direction of movement and the form of movement are not limited.

また、運用上、汚染を防止するために、濾過後液が吐出口１３２の下側になるように、濾過前液リザーバ１３の中の液体を管理する。たとえば、濾過後液が吐出口１３２に至った段階で、ポンプ１１２を自動停止するような形態が考えられる。この前提で、排気管路７と貯蔵部１２１ａとが連通する貯蔵部脱気口１２ａを吐出口１３２よりも上側に配置することにより、貯蔵部脱気口１２ａに濾過液が入り込むことを防止することができる。また、貯蔵部脱気口１２ａへの濾過後液の浸入を防ぎつつ、より多くの濾過液を回収するためには、極力、貯蔵部脱気口１２ａは濾過装置１の中心軸に沿って鉛直方向の上側に設置されることが望ましい。 In addition, in order to prevent contamination during operation, the liquid in the pre-filtered liquid reservoir 13 is managed so that the liquid after filtration is located below the discharge port 132 . For example, it is conceivable to automatically stop the pump 112 when the filtered liquid reaches the discharge port 132 . On this premise, by arranging the storage section deaeration port 12a through which the exhaust pipe 7 and the storage section 121a are communicated above the discharge port 132, the filtrate is prevented from entering the storage section deaeration port 12a. be able to. In addition, in order to collect more filtrate while preventing the post-filtration liquid from entering the storage section degassing port 12a, the storage section degassing port 12a should be arranged vertically along the central axis of the filtering device 1 as much as possible. It is desirable to be installed on the upper side of the direction.

さらに、上記のように、濾過後液リザーバ１２の取手６を濾過後液リザーバ１２に対して移動させて、貯蔵部脱気口１２ａと排気口１２ｂとの少なくとも一方と排気管路７とが合致しない非連通状態とした際に、排気管路７と貯蔵部１２１ａとが連通する貯蔵部脱気口１２ａおよび／または排気口１２ｂとを大気開放となるように連通部を配置することができる。すなわち、排気管路７と貯蔵部脱気口１２ａが連通していないときには、貯蔵部脱気口１２ａが外部に対して露出されて貯蔵部１２１ａが大気開放状態となる。排気管路７と排気口１２ｂとが連通していないときには、排気口１２ｂが外部に対して露出されて排気部１２１ｂが大気開放状態となる。また、排気管路７と貯蔵部脱気口１２ａと排気口１２ｂとの位置関係を、貯蔵部脱気口１２ａが外部に対して露出されて貯蔵部１２１ａが大気開放状態となる状態と、排気口１２ｂが外部に対して露出されて排気部１２１ｂが大気開放状態となる状態とが同時に起こるように設定してもよい。これにより、第二状態において、貯蔵部１２１ａを排気の停止と同時に大気開放にすることが可能となる。また、排気管路７と貯蔵部脱気口１２ａが連通しているときには排気管路７と排気口１２ｂとも連通する第一状態が形成され、逆に排気管路７と貯蔵部脱気口１２ａが連通していないときには、排気管路７と排気口１２ｂとも連通せずに大気開放になるような第二状態が形成される。ポンプ１１２が稼動状態においては、取手６を第一状態とすることで排気管路７と貯蔵部脱気口１２ａと排気口１２ｂとを連通させれば貯蔵部１２１ａと排気部１２１ｂとが連通して濾過プロセスが進行する。一方、取手６を排気管路７が、貯蔵部脱気口１２ａと排気口１２ｂと連通しない位置に移動させれば貯蔵部１２１ａと排気部１２１ｂとの連通が断たれ、貯蔵部脱気口１２ａおよび／または排気口１２ｂとが大気開放となって濾過のプロセスの停止とともに、簡易に貯蔵部１２１ａおよび／または排気部１２１ｂの内部を大気環境に戻すことが可能となる。排気管路７が貯蔵部脱気口１２ａと連通せずに大気開放になる第二状態となることで、濾過後液リザーバ１２と濾過前液リザーバ１３とが引き合う力が減少して、濾過後液リザーバ１２と濾過前液リザーバ１３とを容易に分離できる。また、排気管路７が排気口１２ｂと連通せずに大気開放になる第二状態では、ポンプ１１２がたとえ動作していても、排気部１２１ｂが大気開放になっているため、ポンプユニット１１と濾過後液リザーバ１２とが引き合う力が減少して、ポンプユニット１１と濾過後液リザーバ１２とを容易に分離できる。 Furthermore, as described above, the handle 6 of the filtered liquid reservoir 12 is moved with respect to the filtered liquid reservoir 12 so that at least one of the storage section degassing port 12a and the exhaust port 12b and the exhaust pipe line 7 are aligned. The communicating portion can be arranged so that the storage portion degassing port 12a and/or the exhaust port 12b through which the exhaust pipe line 7 communicates with the storage portion 121a is open to the atmosphere when the non-communication state is established. That is, when the exhaust pipe line 7 and the storage section degassing port 12a are not in communication, the storage section degassing port 12a is exposed to the outside and the storage section 121a is open to the atmosphere. When the exhaust pipe line 7 and the exhaust port 12b are not in communication, the exhaust port 12b is exposed to the outside and the exhaust portion 121b is open to the atmosphere. In addition, the positional relationship between the exhaust pipe line 7, the storage vent port 12a, and the exhaust port 12b is divided into a state where the storage vent port 12a is exposed to the outside and the storage portion 121a is open to the atmosphere, and a state where the storage portion 121a is open to the atmosphere. A state in which the port 12b is exposed to the outside and the exhaust portion 121b is open to the atmosphere may be set to occur at the same time. As a result, in the second state, the storage unit 121a can be opened to the atmosphere at the same time as the exhaust is stopped. When the exhaust pipe line 7 and the storage vent port 12a are in communication, a first state is formed in which the exhaust pipe line 7 and the exhaust port 12b are also in communication. is not in communication with the exhaust pipe 7 and the exhaust port 12b, a second state is created in which the air is open to the atmosphere. When the pump 112 is in the operating state, the handle 6 is placed in the first state to allow communication between the exhaust pipe line 7, the storage degassing port 12a, and the exhaust port 12b. Filtration process proceeds. On the other hand, if the handle 6 is moved to a position where the exhaust pipe line 7 does not communicate with the storage portion degassing port 12a and the exhaust port 12b, the communication between the storage portion 121a and the exhaust portion 121b is cut off, and the storage portion degassing port 12a. And/or the exhaust port 12b is opened to the atmosphere to stop the filtration process, and the inside of the storage part 121a and/or the exhaust part 121b can be easily returned to the atmospheric environment. The second state in which the exhaust pipe line 7 does not communicate with the storage unit degassing port 12a and is open to the atmosphere reduces the force of attraction between the post-filtration liquid reservoir 12 and the pre-filtration liquid reservoir 13, and the post-filtration The liquid reservoir 12 and the pre-filtration liquid reservoir 13 can be easily separated. In the second state in which the exhaust pipe line 7 does not communicate with the exhaust port 12b and is open to the atmosphere, even if the pump 112 is operating, the exhaust part 121b is open to the atmosphere. The attraction force between the filtered liquid reservoir 12 and the pump unit 11 can be easily separated from the filtered liquid reservoir 12 .

排気管路７と貯蔵部１２１ａとが連通する貯蔵部脱気口１２ａを吐出口１３２よりも上側に配置することになどで、貯蔵部脱気口１２ａに濾過液が入り込むことを原則防止することができるが、例えば、排気管路７内に濾過液が混入してしまうことが考えられる。濾過液は細かい液滴またはミストの状態で排気管路７に入るため、排気部１２１ｂに侵入する可能性がある。そのため、前記のとおり、排気部１２１ｂにおいて、突起１１３とトラップ１１４とで、ポンプ１１２への液体成分の侵入を防いでいる。これに加えて、本実施の形態では、さらに、排気管路７に一定量の液体が混入した際に、排気管路７を閉止して内部の気体の流れを遮断するような管路遮断装置８を配置している。以下、図５Ａと図５Ｂを参照して、管路を閉止する管路遮断装置８について詳しく説明する。 In principle, the filtrate is prevented from entering the storage section degassing port 12a by arranging the storage section deaeration port 12a through which the exhaust pipe line 7 and the storage section 121a communicate with each other above the discharge port 132. However, it is conceivable that, for example, the filtrate may be mixed into the exhaust pipe line 7 . Since the filtrate enters the exhaust line 7 in the state of fine droplets or mist, it may enter the exhaust portion 121b. Therefore, as described above, the projection 113 and the trap 114 prevent the liquid component from entering the pump 112 in the exhaust portion 121b. In addition to this, in the present embodiment, when a certain amount of liquid is mixed in the exhaust pipe 7, the pipe line blocking device closes the exhaust pipe 7 to block the flow of the gas inside. 8 is placed. Hereinafter, the pipeline blocking device 8 for closing the pipeline will be described in detail with reference to FIGS. 5A and 5B.

管路遮断装置８は排気管路７中に配置される。管路遮断装置８は、液溜り部８ａと浮遊部材８ｂとからなる。排気管路７は、第一排気管路７ａと、第一排気管路７ａと連通する第二排気管路７ｂと、第二排気管路７ｂと連通する第三排気管路７ｃとからなる。上記の貯蔵部脱気口１２ａと接続する部分は第一排気管路７ａであって、排気口１２ｂと接続する部分は第三排気管路７ｃである。第一排気管路７ａと第三排気管路７ｃとは水平方向に穿設され、第二排気管路７ｂは鉛直方向に延在する鉛直方向管路であって、その両端がそれぞれ、第一排気管路７ａと第三排気管路７ｃと連通するようになっている。管路遮断装置８は、第二排気管路７ｂは鉛直方向の下方端部に、第二排気管路７ｂと第三排気管路７ｃとの間に配置される。すなわち、液溜り部８ａは、排気管路７が直角に向きを変化させる位置に配置され、かつ液を受容可能な窪みである。第二排気管路７ｂと第三排気管路７ｃとの交点は鉛直方向に延在する第二排気管路７ｂの最下部にあたり、重力の効果と、第二排気管路７ｂで加速した気体が第三排気管路７ｃに衝突することで、液溜り部８ａ付近で気体中の液体成分が液化しやすくなり、排気管路７の液状の濾過液が液溜り部８ａに溜まりやすくなる。 A line blocking device 8 is arranged in the exhaust line 7 . The conduit blocking device 8 is composed of a liquid reservoir 8a and a floating member 8b. The exhaust pipe 7 includes a first exhaust pipe 7a, a second exhaust pipe 7b communicating with the first exhaust pipe 7a, and a third exhaust pipe 7c communicating with the second exhaust pipe 7b. A first exhaust pipe line 7a is connected to the storage section degassing port 12a, and a third exhaust pipe line 7c is connected to the exhaust port 12b. The first exhaust pipe 7a and the third exhaust pipe 7c are drilled horizontally, and the second exhaust pipe 7b is a vertical pipe extending vertically. It communicates with the exhaust pipe line 7a and the third exhaust pipe line 7c. The pipeline blocking device 8 is arranged at the lower end of the second exhaust pipeline 7b in the vertical direction, between the second exhaust pipeline 7b and the third exhaust pipeline 7c. That is, the liquid reservoir 8a is a recess that is arranged at a position where the direction of the exhaust pipe 7 is changed at a right angle and that can receive the liquid. The intersection of the second exhaust pipe line 7b and the third exhaust pipe line 7c is the lowest part of the second exhaust pipe line 7b extending in the vertical direction. By colliding with the third exhaust pipe line 7c, the liquid component in the gas tends to liquefy near the liquid pool portion 8a, and the liquid filtrate in the exhaust pipe line 7 tends to accumulate in the liquid pool portion 8a.

液溜り部８ａの内には浮遊部材８ｂを配置する。浮遊部材８ｂは濾過する液体よりも比重が小さい材料でできた部材である。形状は、代表的には、球体である。排気管路７に液体が入り込んでいないときには、液溜り部８ａの大きさは、排気管路７の経路上において、浮遊部材８ｂが気体の流れの障害とならないような大きさに設定しておく（図５Ａ）。すなわち、浮遊部材８ｂが気体の流れを阻害することなく、第二排気管路７ｂから第三排気管路７ｃへと気体が流れる流路から浮遊部材８ｂが外れるような大きさおよび形状としておく。そして、液体状態または気体に混じったミスト状態で気体に含まれる液が排気管路７、すなわち第二排気管路７ｂへと侵入した際には、それが液化して液溜り部８ａに溜まる。液溜り部８ａに液が溜まるにつれ、浮遊部材８ｂが液に浮いて、液面の上昇とともに浮上する。浮遊部材８ｂは液溜り部８ａの液体の量にしたがって浮上高さが高くなる。液溜り部８ａと浮遊部材８ｂとの大きさと形状は、液溜り部８ａに所定の量の液体が溜まった際には吸気口１１３ａに至る排気管路７を浮遊部材８ｂが完全に遮る状態（図５Ｂ）となるように設定する。これにより、所定の量の液体が液溜り部８ａに溜まった段階で、浮遊部材８ｂは液溜り部８ａの最上部に阻害位置に位置して、第二排気管路７ｂから第三排気管路７ｃへの流路をふさぐ。第三排気管路７ｃへ気体が流れないことにより、貯蔵部１２１ａから排気部１２１ｂに至る排気管路７を遮断することができる。これにより、液体が吸気口１１３ａからポンプ１１２内に至ることを防止することが可能となる。 A floating member 8b is arranged in the liquid pool portion 8a. The floating member 8b is a member made of a material having a lower specific gravity than the liquid to be filtered. The shape is typically spherical. When no liquid has entered the exhaust pipe 7, the size of the liquid reservoir 8a is set to such a size that the floating member 8b does not hinder the gas flow on the path of the exhaust pipe 7. (Fig. 5A). In other words, the size and shape of the floating member 8b are such that the floating member 8b does not obstruct the flow of gas, and the floating member 8b is removed from the flow path of the gas flowing from the second exhaust pipe 7b to the third exhaust pipe 7c. Then, when the liquid contained in the gas in a liquid state or a mist state mixed with the gas enters the exhaust pipe 7, that is, the second exhaust pipe 7b, it liquefies and accumulates in the liquid reservoir 8a. As the liquid accumulates in the liquid reservoir 8a, the floating member 8b floats on the liquid and rises as the liquid surface rises. The floating height of the floating member 8b increases according to the amount of liquid in the liquid reservoir 8a. The size and shape of the liquid reservoir 8a and the floating member 8b are such that when a predetermined amount of liquid is accumulated in the liquid reservoir 8a, the floating member 8b completely blocks the exhaust pipe 7 leading to the intake port 113a ( (Fig. 5B). As a result, when a predetermined amount of liquid has accumulated in the liquid pooling portion 8a, the floating member 8b is positioned at the topmost position of the liquid pooling portion 8a at the blocking position, and the second exhaust pipe line 7b and the third exhaust pipe line are separated from each other. Block the flow path to 7c. Since the gas does not flow to the third exhaust pipe 7c, the exhaust pipe 7 from the storage portion 121a to the exhaust portion 121b can be blocked. This makes it possible to prevent the liquid from reaching the inside of the pump 112 through the intake port 113a.

管路遮断装置８の浮遊部材８ｂの移動方向は液溜り部８ａの内側の壁面形状によって定まる。たとえば、一の実施の形態では、図５Ａおよび図５Ｂに示すように、浮遊部材８ｂの移動方向は第二排気管路７ｂと第三排気管路７ｃとがなす角を二分するように設定される。たとえば、第二排気管路７ｂと第三排気管路７ｃとが直角である場合には、図５Ａおよび図５Ｂのように、浮遊部材８ｂの移動方向を水平方向に対して４５度の角度に設定する。この場合、液溜り部８ａの中心軸が第三排気管路７ｃに対して４５度の角度となるように設定する。そして、この液溜り部８ａの中心軸周りに浮遊部材８ｂのほぼ直径と等しい壁面を設ける。ただし、図５Ｃに示すように、浮遊部材８ｂの移動方向は第二排気管路７ｂと同じく鉛直方向に設定しても良い。図５Ｃはこの形態の管路遮断装置８である。図５Ｃでは、排気管路７を遮断していない状態の浮遊部材８ｂを実線で示し、排気管路７を遮断している状態の浮遊部材８ｂを破線で示している。この場合には、浮遊部材８ｂの移動方向を鉛直方向に設定する。そして、この液溜り部８ａの中心軸周りに浮遊部材８ｂのほぼ直径と等しい壁面を設ければよい。この形態であっても、排気管路７に液体が入り込んでいないときには、液溜り部８ａの大きさは、排気管路７の経路上において、浮遊部材８ｂが気体の流れの障害とならないような大きさに設定し（図５Ｃの実線）、液溜り部８ａに所定の量の液体が溜まった際には排気管路７を浮遊部材８ｂが完全に遮る状態（図５Ｃの破線）となるように設定すればよい。 The moving direction of the floating member 8b of the conduit blocking device 8 is determined by the shape of the inner wall surface of the liquid reservoir 8a. For example, in one embodiment, as shown in FIGS. 5A and 5B, the moving direction of the floating member 8b is set to bisect the angle formed by the second exhaust line 7b and the third exhaust line 7c. be. For example, when the second exhaust pipe 7b and the third exhaust pipe 7c are perpendicular to each other, the moving direction of the floating member 8b is set at an angle of 45 degrees with respect to the horizontal direction as shown in FIGS. 5A and 5B. set. In this case, the center axis of the liquid pool portion 8a is set to form an angle of 45 degrees with respect to the third exhaust pipe line 7c. A wall surface approximately equal to the diameter of the floating member 8b is provided around the central axis of the liquid reservoir 8a. However, as shown in FIG. 5C, the moving direction of the floating member 8b may be set in the vertical direction as in the case of the second exhaust pipe 7b. FIG. 5C shows a line blocking device 8 of this form. In FIG. 5C, the floating member 8b that does not block the exhaust pipe 7 is indicated by a solid line, and the floating member 8b that blocks the exhaust pipe 7 is indicated by a broken line. In this case, the moving direction of the floating member 8b is set to the vertical direction. A wall surface approximately equal to the diameter of the floating member 8b may be provided around the central axis of the liquid reservoir 8a. Even in this form, when no liquid has entered the exhaust pipe 7, the size of the liquid reservoir 8a is such that the floating member 8b does not interfere with the gas flow on the path of the exhaust pipe 7. 5C), and when a predetermined amount of liquid is accumulated in the liquid reservoir 8a, the floating member 8b completely blocks the exhaust pipe 7 (broken line in FIG. 5C). should be set to

上記説明した実施の形態では、取手６は、濾過後液リザーバ１２の中心軸方向である深さ方向に沿って摺動する例を示した。しかし、取手６の移動方向はこれに限らず、減圧状態（第一状態）と非減圧状態（第二状態）との間の状態変更をできる限り取手６の移動方向は自由に設定できる。たとえば、図６に示すように、取手６を濾過後液リザーバ１２の壁面に垂直な面の法線方向まわりに回転可能な枢軸部を配置して、濾過後液リザーバ１２の壁面に垂直な面の法線方向まわりに回転移動させることにより減圧状態となる（第一状態）と非減圧状態（第二状態）とを実現するように設定することができる。たとえば、図６では、実線で示した取手６が第一状態であり、一点鎖線で示した取手６が第二状態となるように設定してもよい。さらに、図には示していないが、取手６を濾過後液リザーバ１２の表面上に沿って摺動させる形態としてもよい。 In the above-described embodiment, the handle 6 slides along the depth direction, which is the central axis direction of the filtered liquid reservoir 12 . However, the moving direction of the handle 6 is not limited to this, and the moving direction of the handle 6 can be freely set as long as the state can be changed between the decompressed state (first state) and the non-decompressed state (second state). For example, as shown in FIG. 6, the handle 6 is arranged with a pivot that can be rotated around the normal direction of the surface perpendicular to the wall surface of the filtered liquid reservoir 12, and the surface perpendicular to the wall surface of the filtered liquid reservoir 12 is arranged. It can be set to realize a decompressed state (first state) and a non-depressurized state (second state) by rotationally moving around the normal direction of . For example, in FIG. 6, the handle 6 indicated by the solid line may be in the first state, and the handle 6 indicated by the one-dot chain line may be set to be in the second state. Furthermore, although not shown in the drawings, the handle 6 may be slid along the surface of the filtered liquid reservoir 12 .
