生していた。Conventionally, a sand pump has been used to pump up sediment from the water, but in order to position the pump suction port relative to the surface of the sediment, it is necessary to empirically estimate the condition of the surface layer of the sediment based on weather conditions and over time. The decision was made through trial and error, or based on the intuition of the operator, which sometimes resulted in poor sand absorption efficiency and only sewage being pumped up, and depending on the sedimentation state and properties of the sand, the pump's suction Problems such as clogging at the mouth, blades, and outlet of the pump chamber frequently occurred during operation.

ない。Three types of blades are commonly used for sand pumps: bladeless, non-clog, and whirlpool type.
Some have a cutter that pumps up the water along with the sediment, and some have a jet mechanism that uses water or air currents to lift up the sediment that has accumulated on the bottom of the pond and suck it up. Sediment contains not only sand but also liquid, stone chips, and iron pieces, so in addition to the blades and auxiliary mechanisms mentioned above, the blade chamber, suction roller fixed blade, and blade have special shapes. A sand pump that is suitable for sand settling has not yet been found.

しながら、これらが適合する沈砂性状の確率は極くわず
かであって、普遍性はなかったのである。If a sand pump or a simple pipe port is placed on the sand surface near the bottom of the pond to lift sand, the above-mentioned troubles are unavoidable, and when trouble occurs, it is necessary to either move the part above the water surface or Measures were taken to eliminate the cause of the trouble by eliminating sewage from the settling basin.Depending on the nature of the settling basin, this method required forward rotation, i.e., at the suction port, suction operation was reversed to discharge operation. In some cases, control circuits have been constructed to allow automatic operation with time limits, batch limits, and frequency limits, reducing trouble avoidance. However, the probability of sand settling conditions that meet these conditions is extremely small. However, there was no universality.
何れにしろ、下水と共に揚砂する方法としては種々の試
みが成されてはいるもののし渣・石片・鉄片などが混在
している沈砂の場合にはトラブルの発生が多かった。In any case, although various attempts have been made to pump up sand together with sewage, problems often occur when the sand contains sediment, stone chips, iron pieces, etc.
この発明は、このような従来の欠点を解消すべく為され
たもので吸込口下端と砂表面との距離が一定でなくても
、即ち、ランダムな設定位置であっても沈砂を円滑に吸
引し得るのを目的とする。This invention was made to solve these conventional drawbacks, and it is possible to smoothly suck sand even if the distance between the lower end of the suction port and the sand surface is not constant, that is, even if the position is randomly set. The purpose is to do what is possible.
本発明の要点は、吸引管路途中に二重管の内筒が伸縮す
る機構をもったピストンジヨイントを往復動作による推
力によって伸縮をし、回動をすることにある。The gist of the present invention is to use a piston joint, which has a mechanism for expanding and contracting the inner cylinder of a double pipe in the middle of the suction pipe, to expand and contract by the thrust generated by the reciprocating motion, and to rotate the piston joint.

and a suction pipe 5 is provided through the side surface of the separation tank 6. The upper end of the piston joint 2 is connected to the suction pipe 5, and the lower end is connected to the upper end of the suction pipe 5a, so that the short pipe 5b below the suction pipe 5a is near the surface of the sediment 12 deposited on the bottom surface 11 of the sediment basin. Place it like this. An air pipe from the outside is provided in the short pipe 5b.
下水８の下方に堆積の沈砂１２表面から真をポンプ７内
までは全貫通をする配管をする。Below the sewage water 8, piping is provided that completely penetrates from the surface of the sediment 12 deposited to the inside of the pump 7.
床面９に固定の架台１にピストンジヨイント２の上端部
２ｂを固定し、更に架台１とは別途の受台２ａにピスト
ンジヨイント２の下端部２Ｇを固定する。The upper end 2b of the piston joint 2 is fixed to a pedestal 1 fixed to a floor surface 9, and the lower end 2G of the piston joint 2 is further fixed to a pedestal 2a separate from the pedestal 1.

イント４ｂにて接続する。The cylinder 4 is fixed to a mounting base B provided on the frame 1, and the rod 4a of the cylinder is connected by a pin joint 4b fixed to the pedestal 2a.

３図のＡ、Ｂ、Ｃ。The effect of the configuration described above is that when the reciprocating motion of the cylinder 4 is started almost simultaneously with the operation of the vacuum pump 7 and the piston joint 2 is moved up and down, the movement between the inner cylinder and the outer cylinder of the piston joint 2 is caused. iM movement occurs. Due to the expansion and contraction of the piston joint 2, its expansion and contraction length becomes the short pipe 5b.
The vertical stroke length is , and the suction port of the short pipe 5b (A, B, C in Fig. 3).

に分離タンク６内から水分と砂分とを別々に排出する。On the other hand, the sediment 12 passing through the short pipe 5b is discharged into the separation tank 6 through the suction pipe 5 while being subject to fluctuations in passage speed due to relative movement due to expansion and contraction within the piston joint 2 together with the sewage water 8. The inside of the separation tank 6 is always maintained at a vacuum by a vacuum pump 7, and when the contents reach an appropriate level, moisture and sand are separately discharged from the inside of the separation tank 6.
ピストンシロインド２は上下に伸縮すると同時管心を中
心にして回動を与えることも揚砂上から好ましい運転方
法である。沈砂は沈砂池の流入路形状と方向によっては
偏積されていて圧密か進行するとコンクリート状を体す

の吸入口をもった短管５ｂを選択して使用する。It is also a preferable operating method for the piston cylinder 2 to extend and contract up and down and at the same time rotate around the tube center. Depending on the shape and direction of the inlet channel of the settling basin, the sediment may be unevenly piled up and become concrete-like as consolidation progresses.
A short pipe 5b having a suction port is selected and used.
沈砂の堆積が比較的に新しい場合は沈砂そのものが圧密
してないので第３図Ａ、Ｂに示した形状の吸引口が揚砂
効率上から芳しいことを発明者は確認している。The inventor has confirmed that when the sediment is relatively new, the sediment itself is not consolidated, so the suction ports of the shapes shown in FIGS. 3A and 3B are more efficient in terms of sand lifting efficiency.
短管５ｂの先端は、沈砂の表面とある一定の距離を持た

態となり気流に乗って移送される。短管５ｂの先端は第
３図へ〇うツバ状にしている場合には、吸引影響線は末
広がりとなり沈砂表面を攪乱しやすくなる。The tip of the short pipe 5b is kept at a certain distance from the surface of the sediment, and this certain distance is synchronized with the stroke of the cylinder 4 so that the short pipe 5 moves vertically in simple harmonic motion. Due to this operation, the suction influence exerted by the suction pipe on the sand settling surface constantly changes, a turbulent state is generated on the sand settling surface, and the sand is in a disturbed state and is transported along with the air current. If the tip of the short pipe 5b is shaped like a brim as shown in FIG. 3, the suction influence line will widen toward the end, making it easier to disturb the sand surface.

、沈砂性状に対応することができるのである。In addition, in order to avoid uneven accumulation of sand, an elevating device (not shown) is further provided in the suction pipe 5a, and the short pipe 5b is extended and retracted in a double manner, that is, the elongated length of the piston joint 2 plus the elevating and lowering of the suction pipe 5α section. If the length of vertical movement is determined by
本発明は以上に述べた構成と作用によって次のような効
果を有する。The present invention has the following effects due to the configuration and operation described above.
１）沈砂の表面旨さに追随して表層からも揚砂が１１能
であり、沈砂の下層からも揚砂できた。1) Following the surface quality of the settled sand, sand could be lifted from the surface layer as well as from the lower layer of the settled sand.
２）吸入口の上下動によって発生する局部的な水流波が
沈砂に衝撃力となって伝播するので、沈砂は浮遊状態と
なり吸引が容易となった。2) The localized water current waves generated by the vertical movement of the suction port act as an impact force on the sediment and propagate, so the sediment becomes suspended and can be easily sucked.

剪断作用が派生しているので乱流状態を維持しつ〜揚砂
されることから、沈砂の洗浄が行われるし、管内径に詰
り易い木片・ビニールプラスチック類でも通過が容易に
なった。υ Since there is always a shearing action between the inner wall of the suction pipe and the turbid water mixed with sand as it passes through, a turbulent flow is maintained and the sand is lifted up, cleaning the sand and cleaning the pipe. Even wood chips and vinyl plastics, which tend to get stuck in the inner diameter, can now pass through easily.
４）沈砂が圧密してコンクリート状のものでも、吸引口
の形状選択をして回転をしつ瓦の運転をすることによっ
て揚砂が可能となった。4) Even if the sand is compacted and becomes concrete-like, it is now possible to lift sand by selecting the shape of the suction port and operating the tile while rotating.
本発明は上記した効果があることによって、沈砂池の池
底に堆積した沈砂と称する全てを下水と共に揚砂をする
ことができたのである。Due to the above-mentioned effects of the present invention, all of the so-called sediment deposited on the bottom of the settling basin can be pumped up together with sewage water.
