（１）実施形態１
図面により、本発明を説明する。図１は、膜モジュールの縦断面図、図２、図３は膜モジュールの製造方法の説明図である。 (1) Embodiment 1
The present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a membrane module, and FIGS. 2 and 3 are explanatory views of a method for manufacturing the membrane module.

膜モジュール１０は、筒状のハウジング本体１２とキャップ１３とからなるケースハウジング１１内に、所要束数の膜束（中空糸膜束）１５が収容されたものである。   The membrane module 10 has a required number of membrane bundles (hollow fiber membrane bundles) 15 accommodated in a case housing 11 composed of a cylindrical housing body 12 and a cap 13.

ハウジング本体１２は、一端又は両端が開口したもので、側面に液出入口を有していてもよい。キャップ１３は、ハウジング本体１２の開口部を閉塞するもので、液出入口１４を有している。液出入口は、送液ラインに接続される。   The housing body 12 is open at one or both ends, and may have a liquid inlet / outlet on the side surface. The cap 13 closes the opening of the housing body 12 and has a liquid inlet / outlet port 14. The liquid inlet / outlet is connected to a liquid feeding line.

膜束１５の端部同士及び膜束１５の端部とハウジング本体１２の端部内周面は、硬化した接着剤（ウレタン系又はエポキシ系樹脂接着剤等）１６で接着封止されている。   The end portions of the membrane bundle 15 and the end portions of the membrane bundle 15 and the inner peripheral surface of the end portion of the housing main body 12 are bonded and sealed with a cured adhesive (such as urethane-based or epoxy-based resin adhesive) 16.

ハウジング本体１２は、一端又は両端の側面に１つの接着剤の注入孔１７を有しており、注入孔１７は硬化した接着剤１６で閉塞されている。注入孔１７は複数設けることもできる。   The housing body 12 has one adhesive injection hole 17 on one or both side surfaces, and the injection hole 17 is closed with a hardened adhesive 16. A plurality of injection holes 17 may be provided.

次に、図１〜図３により、膜モジュール１０の製造方法を説明する。キャップ１３を取り付ける前のハウジング本体１２内に、所要束数の中空糸膜束１５を収容する。このとき、必要に応じて、特開２００４−８９７９９号公報の図１〜図７に示されるような補強材を用いることができ、公知のポリエチレン製等のネットで中空膜束１５を包み込んでもよい。   Next, a method for manufacturing the membrane module 10 will be described with reference to FIGS. A required number of hollow fiber membrane bundles 15 are accommodated in the housing main body 12 before the cap 13 is attached. At this time, if necessary, a reinforcing material as shown in FIGS. 1 to 7 of JP-A-2004-89799 can be used, and the hollow membrane bundle 15 may be wrapped with a known net made of polyethylene or the like. .

次に、図２に示すように、ポッティング容器２０内に、膜束１５を収容したハウジング本体１２を立てた状態で入れる。膜束１５は、その端面１５ａがポッティング容器２０の底に着かないように支持する。この状態にて、注入容器３０を用いて、１つの注入孔１７から溶融状態の接着剤を注入する。   Next, as shown in FIG. 2, the housing body 12 containing the membrane bundle 15 is put in the potting container 20 in an upright state. The membrane bundle 15 is supported so that the end surface 15 a does not reach the bottom of the potting container 20. In this state, the molten adhesive is injected from one injection hole 17 using the injection container 30.

次に、図３に示すように、注入した接着剤が注入孔１７にまで至った時点で注入を止め、直ちに粘着テープ等の被覆材２５で注入孔１７を塞ぎ、溶融接着剤が注入孔１７から外に溢れ出ることを防止する。その後、そのまま放置して、溶融接着剤を硬化させる。   Next, as shown in FIG. 3, the injection is stopped when the injected adhesive reaches the injection hole 17, and the injection hole 17 is immediately closed with a covering material 25 such as an adhesive tape, and the molten adhesive is injected into the injection hole 17. Prevent overflowing from the outside. Thereafter, the molten adhesive is cured by leaving it as it is.

溶融接着剤が硬化した後、被覆材２５を取り除き、ポッティング容器２０から取り出すと、膜束１５の端部同士及び膜束１５の端部とハウジング本体１２の端部が硬化接着剤１６で接着封止されており、更に注入孔１７も硬化接着剤１６で閉塞されている（図１で示すキャップ１３がない状態）。   After the molten adhesive is cured, the covering material 25 is removed and taken out from the potting container 20, and the ends of the membrane bundle 15 and the ends of the membrane bundle 15 and the end of the housing body 12 are bonded and sealed with the cured adhesive 16. In addition, the injection hole 17 is also closed with the hardened adhesive 16 (the state where there is no cap 13 shown in FIG. 1).

（２）実施形態２
図面により、本発明を説明する。図４、図５は、膜モジュールの縦断面図で、別形態の膜モジュール１０の製造方法を説明するための図である。図１〜図３と同一番号は、同じものであることを意味する。 (2) Embodiment 2
The present invention will be described with reference to the drawings. 4 and 5 are longitudinal sectional views of the membrane module, and are diagrams for explaining a method of manufacturing the membrane module 10 according to another embodiment. The same numbers as those in FIGS. 1 to 3 mean the same thing.

なお、図１〜図３と図４、図５の膜モジュール１０では、図１〜図３の膜モジュール１０がハウジング本体１２の側面端部側に接着剤の注入孔１７を有しているのに対して、図４、図５の膜モジュール１０では、キャップ１３に側面に対向配置された２つの接着剤の注入孔１７ａ、１７ｂを有している点で異なっている。   1 to 3, 4, and 5, the membrane module 10 of FIGS. 1 to 3 has an adhesive injection hole 17 on the side surface end portion side of the housing body 12. On the other hand, the membrane module 10 shown in FIGS. 4 and 5 is different in that the cap 13 has two adhesive injection holes 17a and 17b arranged opposite to the side surfaces.

ハウジング本体１２内に、所要束数の膜束１５を収容する。ハウジング本体１２の端部には、段差面１２ａ及び垂壁面１２ｂからなる段差が設けられており、この部分の構造は図１のものと異なる。なお、必要に応じて、特開２００４−８９７９９号公報の図１〜図７に示されるような補強材を用いることができ、公知のポリエチレン製等のネットで中空膜束１５を包み込んでもよい。   A required number of membrane bundles 15 are accommodated in the housing body 12. The end of the housing body 12 is provided with a step including a step surface 12a and a vertical wall surface 12b, and the structure of this portion is different from that shown in FIG. If necessary, a reinforcing material as shown in FIGS. 1 to 7 of JP-A-2004-89799 can be used, and the hollow membrane bundle 15 may be wrapped with a known net made of polyethylene or the like.

次に、図４に示すように、ハウジング本体１２の開口部にキャップ１３を取り付ける。このとき、キャップ１３の開口部周縁１３ａをハウジング本体１２の段差面１２ａに当接する。この当接部分には積極的な間隙が設けられているものではないが、それぞれの表面粗さに由来する程度の隙間が生じている。   Next, as shown in FIG. 4, a cap 13 is attached to the opening of the housing body 12. At this time, the peripheral edge 13 a of the opening of the cap 13 is brought into contact with the step surface 12 a of the housing body 12. This abutting portion is not provided with a positive gap, but a gap of a degree derived from each surface roughness is generated.

また、キャップ１３の側面の内周面１３ｂとハウジング本体１２の垂壁面１２ｂとの間には隙間が存在している。この隙間は、溶融接着剤の注入経路となる。   A gap exists between the inner peripheral surface 13 b on the side surface of the cap 13 and the vertical wall surface 12 b of the housing body 12. This gap becomes an injection path for the molten adhesive.

このようにハウジング１２の開口部にキャップ１３を取り付けた後、ハウジング本体１２の段差面１２ａとキャップ１３の開口部周縁１３ａとの接触部分の全てを外側から粘着テープ等の被覆材２５ａで覆い、前記接触部分から溶融接着剤が漏れ出ることを防止する。   After attaching the cap 13 to the opening of the housing 12 in this way, the entire contact portion between the step surface 12a of the housing main body 12 and the peripheral edge 13a of the opening of the cap 13 is covered with a covering material 25a such as an adhesive tape from the outside. The molten adhesive is prevented from leaking from the contact portion.

次に、２つの注入容器３０（図２に示すもの）を用いて、２つの注入孔１７ａ、１７ｂから溶融状態の接着剤を注入する。このとき、溶融状態の接着剤は、図５に示すように、中空糸膜束１５同士、中空糸膜束１５とハウジング本体１２の内周面１２ｃとの間、ハウジング本体１２の垂壁面１２ｂとキャップ内周面１３ｂとの間、ハウジング本体１２の段差面１２ａとキャップ１３の開口部周縁１３ａとの間、注入孔１７ａ、１７ｂにまで至る。   Next, using two injection containers 30 (shown in FIG. 2), molten adhesive is injected from the two injection holes 17a and 17b. At this time, as shown in FIG. 5, the melted adhesive includes the hollow fiber membrane bundles 15, between the hollow fiber membrane bundle 15 and the inner peripheral surface 12 c of the housing main body 12, and the vertical wall surface 12 b of the housing main body 12. Between the cap inner peripheral surface 13b, between the step surface 12a of the housing body 12 and the opening peripheral edge 13a of the cap 13, the injection holes 17a and 17b are reached.

そして、注入した溶融接着剤が注入孔１７ａ、１７ｂにまで至った時点で注入を止め、直ちに粘着テープ等の被覆材２５ｂで注入孔１７ａ、１７ｂを塞ぎ、溶融接着剤が注入孔１７ａ、１７ｂから外に溢れ出ることを防止する。その後、そのまま放置して、溶融接着剤を硬化させる。   When the injected molten adhesive reaches the injection holes 17a and 17b, the injection is stopped, and the injection holes 17a and 17b are immediately closed with a covering material 25b such as an adhesive tape, and the molten adhesive is injected from the injection holes 17a and 17b. Prevent overflowing outside. Thereafter, the molten adhesive is cured by leaving it as it is.

溶融接着剤が硬化した後、被覆材２５ａ、２５ｂを取り除くと、中空糸膜束１５の端部同士、中空糸膜束１５の端部とハウジング本体１２の端部、ハウジング本体１２とキャップ１３が硬化接着剤１６で接着封止されており、更に注入孔１７ａ、１７ｂも硬化接着剤１６で閉塞されている。   When the covering materials 25a and 25b are removed after the molten adhesive is cured, the ends of the hollow fiber membrane bundles 15, the end of the hollow fiber membrane bundle 15 and the end of the housing body 12, the housing body 12 and the cap 13 are removed. The cured adhesive 16 is adhesively sealed, and the injection holes 17 a and 17 b are also closed with the cured adhesive 16.

よって、ハウジング本体１２とキャップ１３を同時に一体化できるため、これらを接続するための独立した工程が不要になる。   Therefore, since the housing main body 12 and the cap 13 can be integrated simultaneously, an independent process for connecting them becomes unnecessary.

実施例１
図１〜図３に示す手順で中空糸膜モジュールを製造した。 Example 1
A hollow fiber membrane module was manufactured according to the procedure shown in FIGS.

まず、外径８５ｍｍ、内径７５ｍｍ、高さ４７０ｍｍのポリスルホン製のハウジング本体１２に、計２束の酢酸セルロース系中空糸膜束（１束は約３５００本の中空糸膜からなる）を収容した。   First, a total of two bundles of cellulose acetate-based hollow fiber membranes (one bundle is composed of about 3500 hollow fiber membranes) were accommodated in a polysulfone housing body 12 having an outer diameter of 85 mm, an inner diameter of 75 mm, and a height of 470 mm.

次に、図２に示すようにして、エポキシ樹脂系接着剤（商品名エピコート，ジャパンエポキシレジン社製）を注入孔１７から注入し、注入孔１７にまで接着剤が至った時点で注入を終了させ、直ちに注入孔１７を市販の粘着テープで塞いだ。   Next, as shown in FIG. 2, an epoxy resin adhesive (trade name Epicoat, manufactured by Japan Epoxy Resin Co., Ltd.) is injected from the injection hole 17, and the injection is terminated when the adhesive reaches the injection hole 17. The injection hole 17 was immediately closed with a commercially available adhesive tape.

その状態で１２時間程度放置して、接着剤を硬化させ、図１に示すような中空糸膜モジュールを得た。   In that state, the adhesive was cured by leaving it for about 12 hours to obtain a hollow fiber membrane module as shown in FIG.
