先ず、図１に沿って、本発明の好ましい実施形態の浄水器カートリッジ製造方法によって製造される浄水器カートリッジの一例の構成を説明する。図１は、本発明の好ましい実施形態の浄水器カートリッジ製造方法によって製造される浄水器カートリッジ１０の構成を示す概略的な断面図である。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
First, along FIG. 1, the structure of an example of the water purifier cartridge manufactured by the water purifier cartridge manufacturing method of preferable embodiment of this invention is demonstrated. FIG. 1 is a schematic cross-sectional view showing a configuration of a water purifier cartridge 10 manufactured by a method for manufacturing a water purifier cartridge according to a preferred embodiment of the present invention.

浄水器カートリッジ１０は、一端が開口した有底円筒状のケーシング１２に中央部に、長尺状の中空糸膜編地をロール状に捲くことによって形成された円柱状の中空糸膜モジュール１４が配置され、中空糸膜モジュール１４の外周面とケーシング１２の内周面との間の環状空間に活性炭１６が充填された構成を備えている。   The water purifier cartridge 10 includes a cylindrical hollow fiber membrane module 14 formed by rolling a long hollow fiber membrane knitted fabric in a roll shape at the center of a bottomed cylindrical casing 12 having one end opened. It is arranged and has a configuration in which activated carbon 16 is filled in an annular space between the outer peripheral surface of the hollow fiber membrane module 14 and the inner peripheral surface of the casing 12.

このような浄水器カートリッジ１０の製造では、円筒状のケーシング１２の軸方向一端側の中央部に中空糸膜束が収容された中空糸膜モジュール１４を配置した状態で、ケーシング１２と円柱状の中空糸膜束が収容された中空糸膜モジュールとの間の環状空間に粒状濾過材である活性炭を充填していく。   In the manufacture of such a water purifier cartridge 10, in the state where the hollow fiber membrane module 14 in which the hollow fiber membrane bundle is accommodated is arranged in the central portion on the one end side in the axial direction of the cylindrical casing 12, the casing 12 and the cylindrical shape are arranged. The annular space between the hollow fiber membrane module in which the hollow fiber membrane bundle is accommodated is filled with activated carbon that is a granular filtering material.

次に、この活性炭充填について説明する。
図２は、この活性炭充填に使用される活性炭充填補助具２０の斜視図であり、図３は活性炭充填補助具２０の平面図である。 Next, this activated carbon filling will be described.
FIG. 2 is a perspective view of the activated carbon filling auxiliary tool 20 used for this activated carbon filling, and FIG. 3 is a plan view of the activated carbon filling auxiliary tool 20.

活性炭充填補助具２０は、上述した浄水器カートリッジ１０のような、円筒状の本体容器の軸方向一端側の中央部に中空糸膜束が収容された中空糸膜モジュール（または円柱状の中空糸膜束）が配置され、周縁部に粒状濾過材である活性炭が充填された構造を有する浄水器カートリッジ１０を製造する際に、円筒状の本体容器の内周面と中空糸膜モジュールの外周面との間の環状空間に活性炭を充填する際に使用される器具である。   The activated carbon filling auxiliary tool 20 is a hollow fiber membrane module (or a cylindrical hollow fiber) in which a hollow fiber membrane bundle is housed in a central portion on one axial end side of a cylindrical main body container, such as the water purifier cartridge 10 described above. When manufacturing a water purifier cartridge 10 having a structure in which activated carbon, which is a granular filter material, is disposed at the periphery, an inner peripheral surface of a cylindrical main body container and an outer peripheral surface of a hollow fiber membrane module It is an instrument used when filling the annular space between and with activated carbon.

活性炭充填補助具２０は、筒状の枠体２２と、枠体２２内に取付けられた円錐状の偏向部材２４とを備えている。円錐状の偏向部材２４は、上下方向の中心軸線が円筒状の枠体２２の径方向中心軸線と一致するように、枠体２２内に配置されている。活性炭充填補助具２０は、筒状の枠体２２の外径が、浄水器モジュール１０のケーシング１２の外径を略等しい寸法形状を備えている。   The activated carbon filling auxiliary tool 20 includes a cylindrical frame body 22 and a conical deflecting member 24 attached in the frame body 22. The conical deflection member 24 is disposed in the frame body 22 so that the center axis in the vertical direction coincides with the center axis in the radial direction of the cylindrical frame body 22. The activated carbon filling auxiliary tool 20 has a shape in which the outer diameter of the cylindrical frame 22 is substantially equal to the outer diameter of the casing 12 of the water purifier module 10.

偏向部材２４の下端縁と円筒状の枠体２２の内周面下端との間には、４つの弧状の開口部２６が形成されている。本実施形態では、開口部２６は、偏向部材２４の下端縁と円筒状の枠体２２の内周面下端とを接続する複数のブリッジ部２８によって区切られている。   Four arc-shaped openings 26 are formed between the lower end edge of the deflection member 24 and the lower end of the inner peripheral surface of the cylindrical frame 22. In the present embodiment, the opening 26 is partitioned by a plurality of bridge portions 28 that connect the lower end edge of the deflection member 24 and the lower end of the inner peripheral surface of the cylindrical frame 22.

本実施形態では、弧状開口２６は、内径部２６ａが、中空糸膜モジュール１４の外周面の外径より大径であり、外径部２６ｂが、ケーシング１２の内径より小径とされている。したがって、弧状開口２６は、中空糸膜モジュール１４（中空糸膜束）の外径より大径かつ筒状ケーシングの内径より小径の円に沿って延びている。そして、弧状開口２６の幅は、中空糸膜モジュール１４の外周面１４ａとケーシング１２の内周面１２ａとの間の幅より狭くなっている。   In the present embodiment, the arc-shaped opening 26 has an inner diameter portion 26 a having a larger diameter than the outer diameter of the outer peripheral surface of the hollow fiber membrane module 14 and an outer diameter portion 26 b having a smaller diameter than the inner diameter of the casing 12. Therefore, the arc-shaped opening 26 extends along a circle having a diameter larger than the outer diameter of the hollow fiber membrane module 14 (hollow fiber membrane bundle) and smaller than the inner diameter of the cylindrical casing. The width of the arc opening 26 is narrower than the width between the outer peripheral surface 14 a of the hollow fiber membrane module 14 and the inner peripheral surface 12 a of the casing 12.

次に、本発明の好ましい実施形態の浄水器カートリッジ製造方法における活性炭充填について説明する。
図４は、本発明の好ましい実施形態の浄水器カートリッジ製造方法における活性炭充填工程でのケーシングと活性炭充填補助具２０との位置関係を示す概略的な断面図である。 Next, the activated carbon filling in the water purifier cartridge manufacturing method of a preferred embodiment of the present invention will be described.
FIG. 4 is a schematic cross-sectional view showing the positional relationship between the casing and the activated carbon filling auxiliary tool 20 in the activated carbon filling step in the water purifier cartridge manufacturing method of the preferred embodiment of the present invention.

活性炭充填では、先ず、内部の中心に中空糸膜カートリッジ１４が中央の所定位置に取付けられたケーシング１２を、開口端が上方に向くようにして、加振機能を備えた載置台３０に載置する。次いで、ケーシング１２の開口端に、活性炭充填補助具２０を、枠体２２がケーシング１２と外周壁と整列するように載置する。   In the activated carbon filling, first, the casing 12 having the hollow fiber membrane cartridge 14 attached to the center at a predetermined position in the center is placed on a mounting table 30 having a vibration function so that the opening end faces upward. To do. Next, the activated carbon filling auxiliary tool 20 is placed on the open end of the casing 12 so that the frame 22 is aligned with the casing 12 and the outer peripheral wall.

上述したように、活性炭充填補助具２０の弧状開口２６は、内径部２６ａが、中空糸膜モジュール１４の外周面の外径より大径であり、外径部２６ｂが、ケーシング１２の内径より小径とされている。したがって、弧状開口２６の幅は、中空糸膜モジュール１４の外周面とケーシング１２の内周面との間の幅より狭く設定されている。   As described above, the arc-shaped opening 26 of the activated carbon filling auxiliary tool 20 has an inner diameter portion 26 a having a larger diameter than the outer diameter of the outer peripheral surface of the hollow fiber membrane module 14 and an outer diameter portion 26 b having a smaller diameter than the inner diameter of the casing 12. It is said that. Therefore, the width of the arc-shaped opening 26 is set to be narrower than the width between the outer peripheral surface of the hollow fiber membrane module 14 and the inner peripheral surface of the casing 12.

したがって、活性炭充填補助具２０が、枠体２２がケーシング１２の外周壁と整列するように、ケーシング１２上に載置されると、弧状開口２６は、ケーシング１２の内周面とケーシング１２内に配置された中空糸膜モジュール１４の外周面との間の環状空間と上下方向に整列することになる。   Therefore, when the activated carbon filling auxiliary tool 20 is placed on the casing 12 such that the frame body 22 is aligned with the outer peripheral wall of the casing 12, the arc-shaped opening 26 is formed in the inner peripheral surface of the casing 12 and in the casing 12. It aligns with the annular space between the outer peripheral surfaces of the arranged hollow fiber membrane modules 14 in the vertical direction.

次いで、載置台の加振機構を作動させながら、活性炭充填補助具２０の上方から、活性炭１６を流し込む。活性炭１６は、図４に矢印Ａで示されるように、円錐状の偏向部材２４の斜面に沿って流れ、図４に矢印Ｂで示されるように、偏向部材２４の下端縁に設けられた弧状の開口２６を通って、ケーシング１０に流入する。   Next, the activated carbon 16 is poured from above the activated carbon filling auxiliary tool 20 while operating the excitation mechanism of the mounting table. The activated carbon 16 flows along the inclined surface of the conical deflecting member 24 as indicated by an arrow A in FIG. 4, and the arc shape provided at the lower end edge of the deflecting member 24 as indicated by an arrow B in FIG. 4. Through the opening 26 and into the casing 10.

上述したように、弧状開口２６は、ケーシング１２の内周面とケーシング１２内に配置された中空糸膜モジュール１４の外周面との間の環状空間と上下方向に整列しているので、弧状開口２６を通ってケーシング１０に流入する活性炭１６は、図３に矢印Ｃで示されるように、この環状空間に落下していくことになる。上述したように、活性炭の充填作業中に、載置台の加振機構が作動させられているので、環状空間に落下した活性炭は、隙間無く環状空間内に充填されていく。
所定量の活性炭が充填されると、充填工程が終了する。 As described above, the arc-shaped opening 26 is aligned with the annular space between the inner peripheral surface of the casing 12 and the outer peripheral surface of the hollow fiber membrane module 14 disposed in the casing 12 in the vertical direction. The activated carbon 16 flowing into the casing 10 through 26 falls into the annular space as indicated by an arrow C in FIG. As described above, since the excitation mechanism of the mounting table is activated during the filling operation of the activated carbon, the activated carbon that has dropped into the annular space is filled into the annular space without any gap.
When the predetermined amount of activated carbon is filled, the filling process is finished.

活性炭としては、粉末状活性炭、粒状活性炭等が使用される。また、活性炭に代えて、分子吸着樹脂、ゼオライト、モレキュラーシーブ、キレート樹脂、イオン交換樹脂、亜硫酸カルシウム、コーラルサンド、麦飯石、医王石、トルマリン、これらの混合物を使用してもよい。   As the activated carbon, powdered activated carbon, granular activated carbon or the like is used. Further, instead of activated carbon, molecular adsorption resin, zeolite, molecular sieve, chelate resin, ion exchange resin, calcium sulfite, coral sand, barley stone, Ioishi, tourmaline, or a mixture thereof may be used.
