本考案は、浄水場などの沈殿槽のホツパーにお
ける汚泥排出促進装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for promoting sludge discharge in a hopper of a settling tank in a water purification plant or the like.
従来、この種の汚泥排出装置としては、単に噴
出孔を隔設したに過ぎないパイプをホツパーの内
壁面に露出して取り付けていたのである。
Conventionally, in this type of sludge discharge device, a pipe, which is simply a pipe with a spout hole provided therebetween, has been installed so as to be exposed on the inner wall surface of the hopper.
この方式によると、噴出孔から噴出される流体
によつては、一直線状の噴射水膜が作成されるに
過ぎないのであり、汚泥排出に適した良好な促進
水膜の形成は不可能であるばかりでなく、露出状
態にあるパイプが抵抗となつて高濃度、小容量の
汚泥排出ができなかつた。 According to this method, depending on the fluid ejected from the nozzle hole, only a linear jet water film is created, and it is impossible to form a good promoting water film suitable for sludge discharge. Not only that, but the exposed pipes acted as resistance, making it impossible to discharge small volumes of highly concentrated sludge.
しかも、噴出孔から流体が噴出している場合に
はそれなりの汚泥排出効果があるとしても、流体

出孔を介してパイプにまで逆流するおそれを有
し、汚泥や塵芥などによつて噴出孔が目詰まりを
起して再度の流体噴出に支障を生じるものであつ
た。 Moreover, even if fluid is spewing out from the spouting hole and has a certain sludge discharge effect, if the fluid spewing is stopped, there is a risk that the fluid in the sedimentation tank will flow back through the spouting hole and into the pipe. The ejection holes were clogged with sludge, dust, etc., and it was difficult to eject the fluid again.
解決しようとする問題点は、従来の汚泥排出促
進装置はその成果が確実ではなく、しかも、再三
にわたる保守管理を必要としていたのである。
The problem to be solved is that the results of conventional sludge discharge accelerators are not reliable, and moreover, they require repeated maintenance.

The present invention includes a main pipe 8 buried in the inner wall of the hopper 11, and branches branched from the main pipe 8.
A branch pipe 9 installed on the inner wall surface of the hopper 11, a relay pipe 3 attached to the branch pipe 9, a nozzle body 1 connected to the relay pipe 3 and having a flow path 7 bent downward at right angles, and a nozzle. A float 4 with a small specific gravity that is built into the main body 1 and closes the flow path 7 of the nozzle main body 1 from below, a stopper 6 that prevents the float 4 from descending, and a float 4 that is connected to the nozzle main body 1 below the stopper 6 and introduced It consists of a jet nozzle 2 whose mouth 5 communicates with a flow path 7.

When water is sent from the main pipe to the nozzle body via branch pipes and relay pipes, the float is pushed down by water pressure, communicates the flow path with the inlet, and jets out fluid from the jet nozzle, causing the sludge to flow out. Subject to discharge.

Compared to the conventional straight-line sprayed water film from the jet hole formed in the pipe, it has a wide-angle shape and has a high concentration,
Small volumes of sludge can be discharged efficiently.

Hereinafter, an embodiment of the present invention will be described based on the drawings. A main pipe 8 is buried in the inner wall of the hopper 11 of the sedimentation tank, and a branch pipe 9 is branched from the main pipe 8. Installed on the wall.
そして、枝管９には流路７が形成された中継管
３が取り付けられ、中継管３には流路７を下方へ
直角方向に屈曲させたノズル本体１が接続されて
いる。 A relay pipe 3 in which a flow path 7 is formed is attached to the branch pipe 9, and a nozzle main body 1 in which the flow path 7 is bent downward at right angles is connected to the relay pipe 3.
ノズル本体１には、ノズル本体１の流路７を下
方から閉塞する比重の小なるフロート４が内蔵さ

設けられている。 The nozzle body 1 has a built-in float 4 with a small specific gravity that closes the flow path 7 of the nozzle body 1 from below, and is provided with a stopper 6 that prevents the float 4 from lowering.
ノズル本体１のストツパー６の下方には、導入
口５を流路７と連通させた噴出ノズル２が接続さ

た汚泥である。 A jet nozzle 2 is connected below the stopper 6 of the nozzle body 1, with an inlet 5 communicating with a flow path 7. 10 is sludge deposited in the hopper 11 of the settling tank.
本考案は上記のように構成され、ホツパー内部

The present invention is constructed as described above, and it is possible to form a good promoting water film suitable for discharging sludge inside the hopper.In addition, since the main pipe is buried in the hopper's inner wall, resistance is small, and high concentration and Even small volumes of sludge can be discharged reliably.
しかも、ノズル本体には浮力によつて流路を閉

おそれを防止し、汚泥や塵芥などによる目詰まり
などの支障の発生を解消できるのである。 Furthermore, since the nozzle body has a built-in float that blocks the flow path using buoyancy, it prevents the fluid in the sedimentation tank from flowing back even when the fluid jetting is stopped, and prevents the possibility of the fluid from flowing backwards due to sludge, dust, etc. This can eliminate problems such as clogging.
