Description

【０００１】
【発明の属する技術分野】
本発明は薬筒、更に詳しくは、汚水の消毒のために使用した場合に、薬剤（例えば、固形塩素剤）の種類の相違、汚水の温度や流量の変動の影響を受けることなく、常に安定した汚水中の薬剤濃度（例えば、塩素濃度）を得ることができ、例えば浄化槽に用いられる消毒用薬筒として好適な薬筒に関するものである。
【０００２】
【従来の技術】
従来より、消毒剤などの薬剤（例えば固形塩素剤）を充填した薬筒を浄化槽の沈澱室から消毒室への汚水の流路に設置し、薬筒の下部に形成した孔を通じて消毒剤と汚水を接触させる汚水処理方法、及びこの方法に使用する薬筒が一般的に知られている。
【０００３】
具体的には例えば、前記汚水処理方法において汚水（処理水）に対して所定の割合で消毒剤を溶解させる手段として、処理水に対する薬筒の浸漬深さを変化させる方法及びその装置（実公昭５０−５２４２号公報）；薬筒の覆管を回転せしめて薬筒における通水孔の開口度を変化させる方法及びその装置（実公昭５０−５６０３号公報）；流水量に応じて処理水の流路に薬筒を複数個設ける方法及びその装置（特公昭５１−１８３９５号公報）；汚水の流路にＶ字状の堰き止め具を設置し堰き止め具の屈曲部に放水口を設け、該放水口の流れ方向に対して後方部分に薬筒を設置する方法及びその装置（実公昭６１−７８４０号公報）；或いは、沈澱室に連接して沈澱室から流出した汚水を集合させる貯留室を設け、薬筒の側壁中間部に縦長状の孔を形成し且つその下部に排水口を設け、この薬筒を貯留室の低部に穿設した通孔に挿嵌して定着し、汚水を薬筒の側壁の縦長状の孔より流下させ、薬筒低部の排水口より流出させ、且つ薬筒を貯留室の低部に穿設した通孔に上下に位置調節できるように設置し、汚水の液温に応じてその高さを調節する方法及びその装置（特開平４−１２６５８８号公報）等が知られている。
【０００４】
【発明が解決しようとする課題】
前記従来技術の方法及び装置では、沈澱室から消毒室に到る汚水の流路に消毒剤などの薬剤を充填した薬筒を設置し、薬筒の下部に形成した孔を通じて薬剤と汚水が接触する。しかしながら、薬剤には性状（例えば大きさ、形状、材質、物性等）を異にする種々のものが存在し、例えば薬剤として消毒剤の一種である固形塩素剤を取り上げてみても、固形塩素剤の種類によっては、例えば塩素化イソシアヌル酸と高度晒粉では水（汚水）に対する溶解性が異なる。それ故、前記従来技術の方法を適用しても、同一の薬筒を用いて、薬剤の種類の相違、汚水の温度や流量の変動の影響を受けることなく、常に安定した汚水中の塩素濃度を得ることはできなかった。
【０００５】
本発明は前記従来技術における問題点を解決するためのものであり、その目的とするところは、水（汚水）に対する溶解性が異なる種々の薬剤を使用した場合でも、汚水の温度や流量の変動の影響を受けることなく、常に安定した汚水中の薬剤濃度を容易に得ることができる薬筒を提供することにある。
【０００６】
【課題を解決するための手段】
即ち本発明の薬筒は、薬剤を充填するための内円筒と、内円筒の支持台の機能を有する外円筒よりなる薬筒であって、
内円筒の下部側面に内円筒の円周方向に沿って一定間隔で複数個のスリットが設けられ、スリット上部の内円筒の外側にネジ部が設けられ、内円筒の底部の中央部に円形の孔が設けられ且つ内円筒の底部に外側に突出する凸部が設けられ、外円筒の上部の内側に、内円筒のネジ部に螺合し且つ薬筒の高さを調節するためのネジ部が設けられ、外円筒の下部に、第一開口部が設けられ且つ第一開口部の反対側に第一開口部よりも小さい第二開口部が設けられてなることを特徴とする〔以下、ｉと称する〕。
【０００７】
本発明の薬筒においては、処理すべき汚水（処理水）の流入口として第一開口部及び第二開口部の何れかを選択することにより、又、内筒及び外筒の何れかを回転させて内円筒のスリットの露出部分（内円筒のスリットと第一開口部又は第二開口部の重なり部分）を調整し且つ薬筒の高さを変えて薬剤の処理水への浸漬深さを加減することにより、薬剤の溶解度が制御される。

vi) 薬剤が固形塩素剤であり且つ浄化槽の消毒に用いられるｉの薬筒。
vii)凸部が円形の孔の周囲に設けられた高さ０．５〜３ｍｍの凸条であり、第一開口部が切欠き部であり且つ外円筒を高さ方向に垂直な方向で切断した場合の断面円に対する中心角で９０〜１３０度の範囲で設けられ、第二開口部が切欠き部であり且つ前記断面円に対する中心角で５〜２５度の範囲で設けられ、薬剤が固形塩素剤であり且つ浄化槽の消毒に用いられるｉの薬筒。
【０００９】
本発明の薬筒において使用することができる薬剤は、例えば消毒剤、殺菌剤、腐蝕防止剤、洗浄剤、着色剤等の中から目的に応じて適宜選択すればよい。更に具体的には、消毒剤は例えば塩素系消毒剤として慣用されるもの、例えば塩素化イソシアヌル酸、高度晒粉等であってよく、これらは特に、固形塩素剤の形態が好ましい。固形塩素剤の大きさ、形状、数は薬筒の大きさに応じて適宜選択してよく、例えば形状は錠剤（例えば円板状）、粒剤（例えば球状，円柱状）などであってよい。
【００１０】
本発明の薬筒は薬剤の種類に応じて種々の用途に使用してよい。薬剤として固形塩素剤を使用した本発明の薬筒は、例えば浄化槽の消毒に用いるのに好適である。
【００１１】
薬筒（内円筒及び外円筒）の材質は、薬剤及び水溶液により腐蝕されないものであればよく、特に限定されないが、通常はポリ塩化ビニル、ポリエチレン、ポリプロピレン等のプラスチック材料が好ましい。これらの材料は単独又は組み合わせて使用することができ、例えば内円筒の材料と外円筒の材料が異なっていてもよい。内円筒及び外円筒の大きさは、用途に応じて、本発明の目的を達成し得る範囲内で適宜選択する。内円筒には適当な蓋を付けることが好ましい。
【００１２】
スリットの大きさ、形状、数は特に限定しないが、例えばスリットの形状が矩形状（又はその変形）である場合には、スリットの高さは内円筒の直径の約１／５〜１／２、スリットの幅（横幅）は内円筒を高さ方向に垂直な方向で切断した場合の断面円に対する中心角で１０〜３０度の範囲が好ましい。又、スリットは内円筒の下端部側面に内円筒の円周方向に沿って、適する数を均等（一定間隔）に設けることが好ましい。
【００１３】
前記スリット上部の内円筒の外側に設けるネジ部は、内円筒の成形時に内円筒の側面をネジ部形状に成形することにより設けてもよいし、又は、別途成形した部材（ネジ部を設けてある）を内円筒の外側に嵌着させることにより設けてもよい。ネジ部の長さは、内円筒の高さの１／２０〜１／５の範囲内にすることが好ましい。
【００１４】

【００１５】
本発明の薬筒の外円筒には、内円筒のネジ部に螺合し得るネジ部を設ける。この構造を有することにより、外円筒に対して内円筒を回転させる（又は、内円筒に対して外円筒を回転させる）と外円筒と内円筒の位置関係を変化させ得るので、薬筒の高さを調節することができる。

【００１９】
以下、本発明の薬筒の使用方法の一例〔薬剤が固形塩素剤であり、浄化槽の消毒に用いる場合〕を説明する。塩素化イソシアヌル酸を固形塩素剤として用いる場合は通常、外円筒の第一開口部（大きい方の開口部）を汚水の流入口とし、更に、水温とか汚水流量に対応して溶解量を調整する場合は、外円筒を回転させることにより内円筒のスリットの露出部分を調整し、汚水の流入量を制御する。加えて、前記回転により薬筒の高さも調節し得るので、処理水への薬剤（錠剤）の浸漬深さを加減し、薬剤（錠剤）の溶解度を制御し、好ましい塩素濃度を保つようにすることができる。
【００２０】
塩素化イソシアヌル酸より溶解性の高い高度晒粉を薬剤として用いる場合は、前記と反対に外筒の第二開口部（小さい方の開口部）を汚水の流入口とし、以下前記と同様にして、好ましい塩素濃度を保つようにすることができる。
