Description
【０００１】[0001]
本考案は残留塩素計の検出部の構造に関し、特に、回転電極から信号を検出す るための構造に関する。 The present invention relates to a structure of a detection unit of a residual chlorine meter, and particularly to a structure for detecting a signal from a rotating electrode.
【０００２】[0002]
ポーラログラフ法を応用した残留塩素計では、検出極に回転電極を使用して溶 液中の遊離有効塩素を測定する。電極の回転は、濃度分極によって生じる拡散層 の厚みを薄くして電流感度を上げるため、また、電極の洗浄を行うために行われ る。 In a residual chlorine meter using the polarographic method, a rotating electrode is used as the detection electrode to measure free available chlorine in the solution. The rotation of the electrodes is carried out in order to reduce the thickness of the diffusion layer caused by concentration polarization to increase the current sensitivity and to clean the electrodes.
【０００３】 この場合の回転数は６００rpm （５０Ｈｚ場合）であり、検出部においては、 この回転に支障をきたすことなく、回転電極からの微小な信号を正確に検出する ことが必要である。The number of revolutions in this case is 600 rpm (in the case of 50 Hz), and it is necessary for the detector to accurately detect a minute signal from the rotating electrode without hindering this rotation.
【０００４】 従来、回転電極と電気的に結合された回転軸から信号を検出する構造としては 、回転軸の上部にスリップリングを設け、このスリップリングにブラシを接触さ せる方式のものと、回転軸の上部に水銀溜りを設け、この水銀中に検出棒を挿入 する方式のものとがある。Conventionally, as a structure for detecting a signal from a rotary shaft electrically coupled to a rotary electrode, a slip ring is provided above the rotary shaft and a brush is brought into contact with the slip ring. There is a system in which a mercury pool is provided above the shaft and a detection rod is inserted into this mercury.
【０００５】[0005]
上述したブラシを用いる方法は、接触部（接点）があるため、摩耗による寿命 があり、また、接触面の面圧（すなわち、摩耗が少なく、適性な信号を取出すた めの面圧）を一定に保つために、調整上、複雑な構造となる。 The above-mentioned method using a brush has a contact portion (contact point), so it has a long life due to wear, and the surface pressure of the contact surface (that is, the surface pressure for taking out an appropriate signal with less wear) is constant. In order to keep it in the adjustment, it becomes a complicated structure.
【０００６】 また、水銀を用いたものは、雰囲気（塩素ガス）による水銀劣化時の交換の面 倒や、転倒時の水銀の取扱における安全性（毒性）の問題がある。Further, the one using mercury has problems of troublesome replacement when mercury deteriorates due to the atmosphere (chlorine gas) and safety (toxicity) in handling mercury at the time of falling.
【０００７】 本考案は、このような従来技術の問題点を考慮してなされたものであり、その 目的は、構造が簡単で、保守が容易であり、かつ安全性が良好な残留塩素計の検 出部の構造を提供することにある。The present invention has been made in consideration of the above problems of the prior art, and its purpose is to provide a residual chlorine meter having a simple structure, easy maintenance, and good safety. It is to provide the structure of the detection unit.

本考案は、回転軸における回転電極との電気的結合部分に導電性シリコーンオ イルが注入され、その注入部分に信号検出棒が挿入されており、この信号検出棒 より前記回転電極からの信号が検出されるようになっている。 In the present invention, a conductive silicone oil is injected into a portion of the rotating shaft that is electrically connected to the rotating electrode, and a signal detection rod is inserted into the injected portion. It is supposed to be detected.
【０００９】[0009]
ブラシレスであるために構造が簡単で、摩耗等の問題が生じない。また、シリ コーンオイルは、雰囲気による劣化が少なく、また、安全である。さらに、調度 （粘度）が高く、転倒時に流出しにくい。 Since it is brushless, the structure is simple and problems such as wear do not occur. In addition, silicone oil is safe because it is not easily deteriorated by the atmosphere. In addition, the tongue (viscosity) is high and it does not easily flow out when falling.

次に、本考案の実施例について図面を参照して説明する。図１は本発明の一実 施例の構成を示す、要部断面図である。 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of essential parts showing the configuration of an embodiment of the present invention.
【００１１】 回転電極部１は、指示極（金または白金等）２，銅線３，金属ねじ４等からな り、この電極部１は、金属製の回転軸９に連接している。この回転軸９は、軸受 ５，６，プーリ（回転機構部）７を貫通する形態で、回転自在に取り付けられて いる。The rotating electrode portion 1 is composed of an indicator electrode (gold or platinum or the like) 2, a copper wire 3, a metal screw 4, etc., and the electrode portion 1 is connected to a rotating shaft 9 made of metal. The rotating shaft 9 is rotatably attached in a form of penetrating the bearings 5, 6 and the pulley (rotating mechanism portion) 7.
【００１２】 回転軸９の最上部の窪みには、導電性シリコーンオイル１０が注入されており 、プラスチックのふた１１により封止されている。この導電性シリコーンオイル １０には検出棒８が挿入されており、これにより、電気的な結合が取られている 。A conductive silicone oil 10 is injected into the uppermost hollow of the rotary shaft 9 and is sealed with a plastic lid 11. The detection rod 8 is inserted into the conductive silicone oil 10 to establish an electrical connection.
【００１３】 本実施例では、導電性シリコーンオイル１０として、信越シリコン社の、製品 名「ＫＳ−６６０」を用いている。In this embodiment, as the conductive silicone oil 10, the product name “KS-660” manufactured by Shin-Etsu Silicon Co., Ltd. is used.
【００１４】 図２は電気的な結合を説明するための、検出部１２の拡大断面図である。 回転軸９と信号検出棒８との抵抗値Ｒは、下記（１）式に比例する。 ｛（Ｄ−ｄ）／２｝／πｄＬ・・・・（１） ここで、Ｄは回転軸の内径，ｄは信号検出棒の外径，Ｌは挿入長である。 したがって、ｄとＬを適切な値に選ぶことにより、回転軸と信号検出棒間の抵抗 値Ｒを０Ωに近付けることができ、これにより、良好な信号検出部を設計できる ことになる。FIG. 2 is an enlarged cross-sectional view of the detection unit 12 for explaining the electrical coupling. The resistance value R between the rotary shaft 9 and the signal detection rod 8 is proportional to the following equation (1). {(D-d) / 2} / πdL ... (1) Here, D is the inner diameter of the rotating shaft, d is the outer diameter of the signal detection rod, and L is the insertion length. Therefore, by selecting d and L to appropriate values, the resistance value R between the rotary shaft and the signal detection rod can be brought close to 0Ω, and a good signal detection unit can be designed.
