Description

【発明の属する技術分野】
本発明は、屎尿を含む生活排水を汚水として流入させながら、汚水中の汚物を沈殿、分解させるようにした汚水処理槽において、汚水の水面に浮遊しているスカムと称する浮遊物を、汚水の流れ方向と交差する方向に排出する装置に関する。このような汚水処理槽においては、汚水の表面にはスカムが発生して成長し、槽壁や付属設備に付着して除去が極めて困難になるため、早期に横方向に排出して別途処理をしている。
【0002】
【従来の技術】
従来のスカム排出装置においては、汚水の流れに対して上流側を向く隙間を設けた回動可能の隙間パイプを、多数横方向に連続的に設置し、各隙間パイプの隙間を定期的に順次水面まで下降させてスカムを流出させ、水位が隙間下部まで低下したとき、隙間を水面上に上昇させて流出を停止させるようにしている。
【0003】
そして、汚水の水位を検出する手段として、従来の装置においては、下向きの接触子をもつ水位センサを、箱形のガイド兼波除けの中で上下動するようにチェーンで吊るし、隙間パイプの隙間を流出位置に回動させると同時に接触子を水面検出位置に下げ、スカムが流出して水面が検出位置まで低下したとき隙間パイプを流出阻止位置に戻し、水位センサを上方位置に戻すようにしている。
【0004】
この装置にあっては、水位センサと箱形のガイド兼波除けの間に汚物が詰まりやすく、汚水処理槽の作動が妨害されることがある上に、水位センサと箱形の部材の間の空間が小さいため清掃するのが困難であり、更に、水位センサを移動させるチェーンに伸びが生じることがあり、これにより隙間パイプの作動が不正確になる不都合があった。
【0005】
【発明が解決しようとする課題】
本発明は、前記の従来装置を改善して、掃除が簡単にでき作動が確実な装置を得ることを課題とする。
【0006】
【課題を解決するための手段】
前記の課題の解決手段は、請求項1に記載したとおり、汚水処理槽の内部に流水方向に伸びる隔壁を複数本設け、流水方向と交差する線上に、それぞれの隔壁に固定パイプを固定し、長手方向に汚水流出用の隙間を設けた隙間パイプを、対向する固定パイプに回動自在に支持させ、隙間パイプに回動機構を連設し、所定時間に隙間を流出位置に回動して汚水を流れ込ませ、汚水の水位低下を検出して隙間を流出を阻止する位置に回動させるべくした、スカム排出装置の水位検知装置において、隙間パイプにセクタギヤを固定し、これに噛み合うピニオンを、固定部材に設けた固定軸に軸支させ、汚水の水位を検出して回動機構を作動させる水位センサの接触子を、ピニオンと一体に設けたことを特徴とする。
【0007】
この手段によれば、隙間パイプと水位センサは、セクタギヤとピニオンで連動しているから、両者の位置に狂いが生じることがなく、隙間パイプは正確に回動する。また、機構が簡単で清掃も容易である。
【0008】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態を説明する。図1において、1は汚水処理槽であり、2は隔壁であり、この隔壁2は、矢印Aで示す汚水の流れ方向に平行に複数本設けられている。3はスカム排出装置で、流れ方向Aと交差して設置されており、このスカム排出装置3は、図2に示すように複数個の隙間ユニット4を連続させてなるもので、槽の中央を分水嶺としてここに位置するパイプから、両側へ5度程度の下り勾配をつけて配置され、最下流の隙間ユニット4は、図1に3aで示す位置で汚水処理槽1外に開口している。
【0009】
隙間ユニット4は、一対の隔壁2、2間に設けられ、隔壁2に埋設した取り付け部に固定パイプ5と受けパイプ6が固定され、各受けパイプ6には回動パイプ7が回動自在に支持され、回動パイプ7、7間に、隙間8aを長手方向に開けた隙間パイプ8がフランジ部9で連結されている。図3に示すように前記フランジ部9は、更に隙間パイプ制御装置10に設けた上下動するスピンドル10aにリンク機構10bで接続されている。スピンドル10aは、モータ10cで駆動され、スピンドル軸受10dに案内されて上下動する。
【0010】
汚水の排出限度の水位は、図4、5に示す水位センサ11によって検出される。隙間パイプ8のフランジ部9には、前記リンク機構10bが接続される他にセクタギヤ13が固定され、ピニオン14と噛み合って歯車式水位検知装置を構成している。図5において、固定部材である受けパイプ6にピニオン軸15がアーム15aを介して固定され、ピニオン14と一体のスリーブ16が回転自在に支持され、止め座金17で保持されている。このスリーブ16に前記水位センサ11がアーム11aを介して固定され、接触子12が下向きになった検出位置と横向きになった退避位置に回動される。なお、水位センサ11は、誤動作を防止するために先端位置が僅かに異なる2本の接触子12を備えている。
【0011】
常時は、水位センサ11は図4に仮想線で示す退避位置にあり、隙間パイプ8の隙間8aは、最上位置の阻止位置にある。定期的にタイマが作動して、又は人力で任意に隙間パイプ制御装置10のスピンドル10aを上げると、隙間パイプ8は、矢印B方向に回動して図4の実線位置になり、隙間8aの隙間下縁8a1は、水面L1より下がり、スカムがA1方向に流れ込み、次位のパイプへ流れ出る。このときセクタギヤ13もB方向に回動するから、ピニオン14は時計方向に回動され、水位センサ11は実線位置に下がり、接触子12は下向きになり、その下端は、水面L1より下にくる。
【0012】
スカムの排出が進んで水面が接触子12より下のL2になると、水位センサ11で発生する信号により、隙間パイプ制御装置10のスピドル10aが下がり、隙間パイプ8を矢印C方向に回動させて隙間8aを仮想線の位置に上昇させ、セクタギヤ13とピニオン14の連動により水位センサ11も仮想線の位置に上昇する。一線状に配置された各隙間ユニット4の複数の隙間パイプ8は、制御装置10により、槽の中央側から時間差をおいて隙間8aを下げたのち上昇させる動作を行ない、外端に配置したパイプからスカムを槽外に流出させ、この動作を適宜の間隔で繰り返す。
【0013】
【発明の効果】
以上のとおり、本発明においては、隙間パイプの回動をセクタギヤとピニオンが噛み合う歯車式の装置で水位センサに伝えるから、動作が確実に伝達されて水位センサが正確な信号を伝達する利点があり、また全体が水面上に露出し、構造が簡単であるから、汚物が付着しても清掃が容易にできる利点がある。

BACKGROUND OF THE INVENTION
In the sewage treatment tank in which sewage is allowed to settle and decompose while inflowing domestic wastewater containing urine as sewage, the present invention eliminates floating matter called scum floating on the surface of sewage. The present invention relates to a device for discharging in a direction crossing the flow direction. In such a sewage treatment tank, scum is generated on the surface of the sewage and grows up and adheres to the tank wall and attached equipment, making it extremely difficult to remove. doing.
[0002]
[Prior art]
In the conventional scum discharge device, a number of rotatable gap pipes with gaps facing the upstream side with respect to the flow of sewage are continuously installed in the lateral direction, and the gaps of each gap pipe are periodically and sequentially arranged. When the water level drops to the bottom of the gap, the gap is raised above the water surface to stop the outflow.
[0003]
As a means for detecting the level of sewage, in a conventional apparatus, a water level sensor having a downward contact is hung by a chain so as to move up and down in a box-shaped guide and wave shield, and the gap between gap pipes At the same time, the contactor is lowered to the water level detection position, and when the scum flows out and the water level drops to the detection position, the gap pipe is returned to the outflow prevention position and the water level sensor is returned to the upper position. Yes.
[0004]
In this device, filth is likely to be clogged between the water level sensor and the box-shaped guide and wave breaker, and the operation of the sewage treatment tank may be hindered. Since the space is small, it is difficult to clean, and the chain that moves the water level sensor may be stretched, which causes inconvenience that the operation of the gap pipe becomes inaccurate.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to improve the above-described conventional apparatus to obtain an apparatus that can be easily cleaned and reliably operated.
[0006]
[Means for Solving the Problems]
As described in claim 1, the means for solving the above-mentioned problem is that a plurality of partition walls extending in the direction of flowing water are provided inside the sewage treatment tank, and a fixed pipe is fixed to each partition wall on a line intersecting the direction of flowing water. A gap pipe with a gap for sewage outflow in the longitudinal direction is rotatably supported by an opposing fixed pipe, a rotation mechanism is connected to the gap pipe, and the gap is turned to the outflow position at a predetermined time. In the water level detection device of the scum discharge device, in which sewage is introduced and the water level detection device of the scum discharge device is configured to detect the lowering of the sewage water level and prevent the outflow from flowing out, a sector gear is fixed to the gap pipe, A contact of a water level sensor, which is pivotally supported by a fixed shaft provided on the fixed member, detects the water level of sewage and activates the rotation mechanism, is provided integrally with the pinion.
[0007]
According to this means, since the gap pipe and the water level sensor are interlocked by the sector gear and the pinion, there is no deviation in the position of both, and the gap pipe rotates accurately. Also, the mechanism is simple and easy to clean.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a sewage treatment tank, 2 is a partition wall, and a plurality of partition walls 2 are provided in parallel with the sewage flow direction indicated by an arrow A. Reference numeral 3 denotes a scum discharge device, which is installed so as to intersect the flow direction A. This scum discharge device 3 is formed by connecting a plurality of gap units 4 as shown in FIG. From the pipe located here as a water divide, it is arranged with a downward slope of about 5 degrees on both sides, and the most downstream gap unit 4 opens outside the sewage treatment tank 1 at a position indicated by 3a in FIG.
[0009]
The gap unit 4 is provided between the pair of partition walls 2, 2, and a fixed pipe 5 and a receiving pipe 6 are fixed to an attachment portion embedded in the partition wall 2, and a rotating pipe 7 is rotatable on each receiving pipe 6. A gap pipe 8 that is supported and has a gap 8 a opened in the longitudinal direction is connected between the rotating pipes 7 and 7 by a flange portion 9. As shown in FIG. 3, the flange portion 9 is further connected to a spindle 10a that moves up and down provided in the gap pipe control device 10 by a link mechanism 10b. The spindle 10a is driven by a motor 10c and is moved up and down by being guided by a spindle bearing 10d.
[0010]
The water level at the discharge limit of sewage is detected by a water level sensor 11 shown in FIGS. In addition to the link mechanism 10b being connected to the flange portion 9 of the gap pipe 8, a sector gear 13 is fixed and meshed with the pinion 14 to constitute a gear type water level detection device. In FIG. 5, a pinion shaft 15 is fixed to a receiving pipe 6 that is a fixing member via an arm 15 a, and a sleeve 16 integrated with the pinion 14 is rotatably supported and held by a stopper washer 17. The water level sensor 11 is fixed to the sleeve 16 via an arm 11a, and the contact 12 is rotated to a detection position in which the contact 12 is directed downward and a retracted position in which it is laterally directed. The water level sensor 11 includes two contactors 12 with slightly different tip positions in order to prevent malfunction.
[0011]
Normally, the water level sensor 11 is at the retracted position indicated by the phantom line in FIG. 4, and the gap 8a of the gap pipe 8 is at the uppermost blocking position. If the timer is periodically activated or the spindle 10a of the gap pipe control device 10 is arbitrarily raised manually, the gap pipe 8 rotates in the direction of arrow B to the solid line position in FIG. The lower gap edge 8a1 is lowered from the water surface L1, and the scum flows in the A1 direction and flows out to the next pipe. At this time, since the sector gear 13 is also rotated in the B direction, the pinion 14 is rotated clockwise, the water level sensor 11 is lowered to the solid line position, the contact 12 is directed downward, and the lower end thereof is below the water surface L1. .
[0012]
When the discharge of the scum progresses and the water surface becomes L2 below the contactor 12, the spidle 10a of the gap pipe control device 10 is lowered by the signal generated by the water level sensor 11, and the gap pipe 8 is rotated in the direction of arrow C. The gap 8a is raised to the position of the imaginary line, and the water level sensor 11 is also raised to the position of the imaginary line by the interlocking of the sector gear 13 and the pinion 14. The plurality of gap pipes 8 of each gap unit 4 arranged in a straight line are pipes arranged at the outer end by the controller 10 to lower and raise the gap 8a with a time difference from the center side of the tank. The scum is allowed to flow out of the tank, and this operation is repeated at appropriate intervals.
[0013]
【The invention's effect】
As described above, in the present invention, since the rotation of the gap pipe is transmitted to the water level sensor by the gear type device in which the sector gear and the pinion mesh with each other, there is an advantage that the operation is transmitted reliably and the water level sensor transmits an accurate signal. Also, since the entire structure is exposed on the water surface and the structure is simple, there is an advantage that cleaning can be easily performed even if dirt is attached.
