この考案は下水処理場などの沈澱池に沈澱する汚泥をサ
イホンによって吸上げるサイホン式採泥機に係り、特に
サイホンの作動状態を検出する装置を備えたサイホン式
採泥機に関する。[Detailed description of the invention] This invention relates to a siphon-type sludge collecting machine that uses a siphon to suck up sludge that settles in sedimentation ponds such as sewage treatment plants, and in particular, the siphon-type sludge collecting machine is equipped with a device that detects the operating state of the siphon. Regarding machines.
下水処理場などの沈澱池の底に沈澱する汚泥を排出する
ため、サイホン式採泥機が知られている。BACKGROUND ART Siphon-type sludge collectors are known for discharging sludge that settles at the bottom of settling tanks in sewage treatment plants and the like.
この採泥機は沈澱池の側壁上に設置したレールの上を走
行する桁よりサイホン管を懸垂し、その一端を沈澱池の
底に開口させ、他端を沈澱池と並設した水路の中に開口
させて、サイホン作用によって沈澱した汚泥を吸上げて
水路に排出するものである。This sediment collecting machine suspends a siphon pipe from a girder that runs on a rail installed on the side wall of a sedimentation basin, with one end opening at the bottom of the sedimentation basin and the other end into a waterway parallel to the sedimentation basin. The sludge is opened to suck up the settled sludge by siphoning and discharged into the waterway.
このようなサイホン式採泥機のサイホンの作動状況を監
視するため、従来、例えば吐出管にガラス製の覗き窓を
付設するなどしていたが、ガラスが曇って内部の汚泥吐
出状況を確認することが困難であった。In order to monitor the operating status of the siphon in such a siphon-type sludge collecting machine, conventionally, for example, a glass viewing window was attached to the discharge pipe, but the glass became cloudy and the internal sludge discharge status could be checked. It was difficult.
従って、汚泥吐出状況に呼応してサイホンの作動を調節
することも困難であった。Therefore, it is also difficult to adjust the operation of the siphon in response to the sludge discharge situation.
この考案の目的は、前記従来技術の欠点を解消し、簡単
に、常に確実にサイホンの作動状況を検出、制御しうる
装置を備えたサイホン式採泥機を提供するにある。The purpose of this invention is to eliminate the drawbacks of the prior art and to provide a siphon-type sludge collector equipped with a device that can easily and always reliably detect and control the operating status of the siphon.
この目的は本考案によれば、サイホン式採泥機において
吐出管の先端に固定した開閉自在の弁体と、該弁体を開
閉するバネと、該バネの運動に連動するリミットスイッ
チとを付設することによって遠戚される。This purpose, according to the present invention, is to provide a siphon-type sediment collecting machine with a valve body fixed to the tip of the discharge pipe that can be opened and closed, a spring that opens and closes the valve body, and a limit switch that is linked to the movement of the spring. become a distant relative.
即ち、この考案は、吐出管の先端に弁を付設し、採泥機
の非作動時にはこの弁をバネの力によって閉じておき、
真空ポンプの作動によりサイホン現象が形成され、汚泥
が吸い上げられ、吐出管に汚泥か゛充満したときに、そ
の汚泥の自重によりバネが撓んで弁が開き、リミットス
イッチを作動させるように構成したものである。That is, in this invention, a valve is attached to the tip of the discharge pipe, and this valve is closed by the force of a spring when the slurry collecting machine is not in operation.
When the siphon phenomenon is created by the operation of the vacuum pump and the sludge is sucked up and the discharge pipe is filled with sludge, the spring is bent by the weight of the sludge, opening the valve and operating the limit switch. be.
このリミットスイッチを所定の吐出速度範囲のときに信
号を発するように設定することにより、汚泥の吐出状態
を常時、簡単に確実に検出することができる。By setting this limit switch to emit a signal when the discharge speed is within a predetermined range, the discharge state of sludge can be easily and reliably detected at all times.
従って、リミットスイッチにより吐出量の低下が検出さ
れたときに、適時に真空ポンプを作動させ、サイホン現
象が好適に形成されたときに、適時に真空ポンプを停止
させることができる。Therefore, when a decrease in the discharge amount is detected by the limit switch, the vacuum pump can be operated in a timely manner, and the vacuum pump can be stopped in a timely manner when a siphon phenomenon has appropriately formed.
このリミットスイッチを、更に真空ポンプのオン・オフ
装置と連動させることにより、真空ポンプの作動、及び
停止を自動的に制御することもできる。By further interlocking this limit switch with an on/off device for the vacuum pump, the operation and stop of the vacuum pump can be automatically controlled.
次に、図面に基づいて本考案を詳述する。Next, the present invention will be explained in detail based on the drawings.

The other end of the suction pipe 5 is connected to a discharge pipe 6 via a horizontal portion to form a siphon pipe, which opens in a water channel 7 arranged in parallel to the sedimentation basin 1.
運転開始時には、桁４の上に設けた真空ポンプ８により
吸上管５及び吐出管６内の空気を排出して真空状態を形
