Description
本発明は、ろ過装置や攪拌装置などの水処理装置に用いる散気管清掃装置および散気管清掃方法に関し、さらに詳しくは、散気管内壁に付着し硬化した汚泥を好適に除去しうる散気管清掃装置および散気管清掃方法に関する。 The present invention relates to an air diffuser cleaning device and an air diffuser cleaning method used in a water treatment device such as a filtration device and an agitator, and more particularly, an air diffuser cleaning device that can suitably remove sludge that has adhered to and hardened the inner wall of the air diffuser. And a method for cleaning an air diffuser.
従来、水処理装置の散気管内に清掃ブラシを通し、散気管内を清掃するようにした汚水処理装置が知られている(例えば、特許文献1参照。)。
水処理装置の散気管から気泡を放出すると、散気管から出て行く気泡と入れ替わるように原水が散気管内に入り、汚泥が散気管の内壁に付着する。この散気管の内壁に付着した汚泥は、散気管に送り込まれた空気により乾燥し、硬化する。そして、ついには汚泥が、散気管内に充満して散気管を詰まらせてしまうこともある。
しかし、上記従来の汚水装置のように清掃ブラシを通すだけでは、散気管内壁に付着し硬化した汚泥を好適に除去できない問題点があった。
そこで、本発明の目的は、水処理装置に用いる散気管内壁に付着し硬化した汚泥を好適に除去しうる水処理装置に用いる散気管清掃装置および散気管清掃方法を提供することにある。
When air bubbles are released from the air diffuser pipe of the water treatment device, the raw water enters the air diffuser pipe so as to replace the air bubbles exiting the air diffuser pipe, and sludge adheres to the inner wall of the air diffuser pipe. The sludge adhering to the inner wall of the diffuser is dried and hardened by the air sent to the diffuser. Eventually, sludge may fill the diffuser and clog the diffuser.
However, there is a problem that the sludge that adheres to the inner wall of the air diffuser and hardens cannot be removed suitably only by passing the cleaning brush as in the conventional sewage apparatus.
Then, the objective of this invention is providing the diffuser pipe cleaning apparatus and diffuser pipe cleaning method used for the water treatment apparatus which can remove suitably the sludge which adhered to the inner wall of the diffuser pipe used for a water treatment apparatus and was hardened | cured.
第1の観点では、本発明は、水処理施設の水槽内水中に気泡を放出するための散気管および前記散気管に空気を送り込むための送気管のいずれの内径よりも小さい外径を有し且つ重心が回転軸から偏心したビットと、水槽外に置かれるモータと、前記モータから前記送気管内を通り前記散気管まで挿入しうる長さを有し且つ屈曲部がある場合はその屈曲部で曲がると共に前記ビットが振子運動しうる柔軟性を有し前記モータの回転を前記ビットに伝えるフレキシブルシャフトとを具備したことを特徴とする散気管清掃装置を提供する。
上記第1の観点による散気管清掃装置では、フレキシブルシャフトの先端に取り付けたビットを送気管の水槽外の部分から送気管内に挿入し、送気管を通して散気管に至らせる。そして、モータを回すと、散気管内でビットが回転および振子運動するので、散気管内壁に付着し乾燥・硬化した汚泥を好適に除去することが出来る。また、汚泥が散気管内に充満して散気管を詰まらせてしまっている場合でも、汚泥を好適に除去することが出来る。
In a first aspect, the present invention has an outer diameter that is smaller than the inner diameter of any of an air diffuser for discharging bubbles into water in a water tank of a water treatment facility and an air diffuser for feeding air into the air diffuser. And a bit whose center of gravity is eccentric from the rotation axis, a motor placed outside the water tank, and a length that can be inserted from the motor through the air supply pipe to the air diffuser and has a bent part, the bent part. The air diffuser cleaning device is provided with a flexible shaft that bends at the same time and has a flexibility that allows the bit to perform pendulum motion and transmits the rotation of the motor to the bit.
In the air diffuser cleaning device according to the first aspect, a bit attached to the tip of the flexible shaft is inserted into the air supply pipe from a portion outside the water tank of the air supply pipe, and reaches the air diffusion pipe through the air supply pipe. Then, when the motor is rotated, the bit rotates and pendulums in the diffuser tube, so that the sludge adhered to the inner wall of the diffuser tube and dried and hardened can be suitably removed. Moreover, even when the sludge is filled in the diffuser tube and clogs the diffuser tube, the sludge can be suitably removed.
ビットの外径を送気管および散気管のいずれの内径よりも小さくしたのは、管内を通すためである。
また、ビットの重心を回転軸から偏心させたのは、管内径よりも外径が小さいビットを振子運動させて、管内壁に当たるまでビットを振るためである。
The reason why the outer diameter of the bit is made smaller than the inner diameter of either the air supply pipe or the air diffuser is to allow passage through the pipe.
Further, the reason why the center of gravity of the bit is eccentric from the rotation axis is that the bit having a smaller outer diameter than the inner diameter of the pipe is moved in a pendulum manner and shaken until it hits the inner wall of the pipe.
フレキシブルシャフトをモータから送気管内を通り散気管まで挿入しうる長さとしたのは、モータを水槽外に置くためである。
また、フレキシブルシャフトは、屈曲部がある場合はその屈曲部で曲がると共に、ビットが振子運動しうる柔軟性を有することが必要である。
The reason why the flexible shaft is long enough to be inserted from the motor through the air supply pipe to the diffuser pipe is to place the motor outside the water tank.
In addition, the flexible shaft needs to bend at the bent portion when there is a bent portion, and to be flexible so that the bit can perform a pendulum motion.
第2の観点では、本発明は、前記第1の観点による散気管清掃装置において、前記フレキシブルシャフトが、前記ビットに一端が連結されるビット連結部と、前記ビット連結部の他端に一端が連結され前記ビット連結部の柔軟性よりも低い柔軟性を有する中間部の少なくとも2段になっていることを特徴とする散気管清掃装置を提供する。
上記第2の観点による散気管清掃装置では、フレキシブルシャフトをビット連結部と中間部の少なくとも2段とし、ビット連結部の柔軟性を相対的に高くし、中間部の柔軟性を相対的に低くした。これにより、ビットは、屈曲部がある場合はその屈曲部で曲がって進み易くなると共に振子運動し易くなる。他方、中間部は、捩れを抑えて、回転を好適に伝達することが出来る。なお、中間部は、ビット連結部に先導されて屈曲部を曲がるので、屈曲部の曲がりに支障を生じない。また、ビット連結部の長さだけビットから離れるので、ビットの振子運動にも支障を生じることはない。
In a second aspect, the present invention provides the diffuser tube cleaning device according to the first aspect, wherein the flexible shaft has a bit connecting portion whose one end is connected to the bit, and one end at the other end of the bit connecting portion. An air diffuser cleaning device is provided which is connected to at least two stages of an intermediate portion having flexibility lower than that of the bit connecting portion.
In the air diffuser cleaning device according to the second aspect, the flexible shaft has at least two stages of the bit connecting portion and the intermediate portion, the flexibility of the bit connecting portion is relatively high, and the flexibility of the intermediate portion is relatively low. did. Thereby, when there exists a bending part, a bit becomes easy to bend and advance at the bending part, and it becomes easy to carry out a pendulum movement. On the other hand, the intermediate portion can transmit the rotation suitably while suppressing the twist. Since the intermediate portion is led by the bit connecting portion and bends the bent portion, there is no problem in bending of the bent portion. Further, since the bit is separated from the bit by the length of the bit connecting portion, the pendulum movement of the bit is not hindered.
第3の観点では、本発明は、水処理施設の水槽内水中に気泡を放出するための散気管および前記散気管に空気を送り込むための送気管を備えた水処理用散気装置に対して、請求項1または請求項2に記載の前記フレキシブルシャフトの先端に付けた前記ビットを水槽外から前記送気管内を通して前記散気管まで挿入し前記モータで駆動して回転および振子運動させ、散気管内壁に付着し乾燥・硬化した汚泥を前記ビットで粉砕・剥離することを特徴とする散気管清掃方法を提供する。
上記第3の観点による散気管清掃方法では、フレキシブルシャフトの先端に取り付けたビットを送気管の水槽外の部分から送気管内に挿入し、送気管を通して散気管に至らせる。そして、モータを回すと、散気管内でビットが回転および振子運動するので、散気管内壁に付着し乾燥・硬化した汚泥を好適に除去することが出来る。また、汚泥が散気管内に充満して散気管を詰まらせてしまっている場合でも、汚泥を好適に除去することが出来る。
In a third aspect, the present invention relates to an air diffuser for water treatment provided with an air diffuser for releasing bubbles into water in a water tank of a water treatment facility and an air supply pipe for sending air into the air diffuser. The bit attached to the tip of the flexible shaft according to claim 1 or 2 is inserted from the outside of the water tank into the air diffuser through the air supply tube, and is driven by the motor to rotate and pendulum, thereby the air diffuser. An air diffuser cleaning method is provided, characterized in that sludge adhering to an inner wall and dried and hardened is pulverized and peeled with the bit.
In the air diffuser cleaning method according to the third aspect, a bit attached to the tip of the flexible shaft is inserted into the air supply pipe from a portion outside the water tank of the air supply pipe, and is led to the air diffuser through the air supply pipe. Then, when the motor is rotated, the bit rotates and pendulums in the diffuser tube, so that the sludge adhered to the inner wall of the diffuser tube and dried and hardened can be suitably removed. Moreover, even when the sludge is filled in the diffuser tube and clogs the diffuser tube, the sludge can be suitably removed.
