一般に汚水処理装置においての最犬の問題点は汚水の流
入量が大きく変動するため曝気室、沈澱卒の容量を非常
に大きくしなければならず経済的でないという欠点があ
る。In general, the most important problem with sewage treatment equipment is that the inflow of sewage fluctuates greatly, so the capacity of the aeration chamber and settling chamber must be extremely large, which is uneconomical.

このように汚水の流入量の時間的変動が大きいのでエア
ーリフト棺ンプを設けて曝気室、沈澱室への流入量を一
定にすることが考えられるが、エアーリフトポンプの場
合空気量が少くして効率を高めるには揚水管の径を小さ
くする必要があり、径を小さくすると汚泥により揚水管
内が閉塞してしまうという問題点がある。Since the amount of sewage flowing into the wastewater fluctuates greatly over time, it is conceivable to install an air lift coffin pump to keep the amount of water flowing into the aeration chamber and settling chamber constant, but with an air lift pump, the amount of air is small. In order to increase efficiency, it is necessary to reduce the diameter of the pumping pipe, but if the diameter is made small, there is a problem that the inside of the pumping pipe will become clogged with sludge.

また揚水管の閉塞を防止するため管径を大きくすると非
常に多量の空気量を必要とし、曝気用と合わせると大容
量の空気ポンプが必要となるのでコスト高．となる問題
点がある。In addition, increasing the pipe diameter to prevent clogging of the pumping pipe requires a very large amount of air, and when combined with aeration, a large-capacity air pump is required, resulting in high costs. There is a problem.

and a valve seat 13.

閉塞部１１の中央部には孔１４を有するマグネットの弁
座１３が設けてあり、孔１４に挿入した棒状弁１５下端
の鉄製の弁部９が弁座１３に磁着されるようになってい
る。A magnetic valve seat 13 having a hole 14 is provided in the center of the closing portion 11, and the iron valve portion 9 at the lower end of the rod-shaped valve 15 inserted into the hole 14 is magnetically attached to the valve seat 13. There is.

are for setting the maximum lowering position and maximum floating position of the push-up tube 5, respectively, and by adjusting the mounting positions of the upper floating height adjustment plate 16 and the lower floating height adjustment plate 7, the push-up tube 5 can be adjusted. The maximum floating position and the maximum descending position are adjusted to adjust the flow rate, and this serves as a flow rate adjustment means.

図中６は送気管であって揚水筒１の下部に位置している
。In the figure, reference numeral 6 denotes an air supply pipe, which is located at the lower part of the water pumping cylinder 1.

また揚水筒１の下部には汚水１９よりも比重の重たい液
体２０がはいっている。Further, a liquid 20 having a higher specific gravity than the waste water 19 is contained in the lower part of the water pumping cylinder 1.

しかして今第１図ａに示すような状態において送気管６
から送られる空気によって押上筒５に空気が溜り、浮力
が生じて揚水筒１内の汚水が第１図ｂに示すようにして
排水口２より流出室８に押出される。However, in the state shown in FIG. 1a, the air supply pipe 6
Air is collected in the lifting cylinder 5 by the air sent from the pumping cylinder 5, and buoyancy is generated, so that the dirty water in the lifting cylinder 1 is pushed out from the drain port 2 into the outflow chamber 8 as shown in FIG. 1b.

次に下浮上高さ調整板１７が第１図Ｃに示すように揚水
筒１上端部の棒状弁保持具２１に当る。Next, the lower floating height adjusting plate 17 hits the rod-shaped valve holder 21 at the upper end of the water pump 1, as shown in FIG. 1C.

この状態で押上筒５が更に上昇すると棒状弁１５の弁部
９がマグネットの弁座１３よりはずれ、押上筒５内の空
気が抜けて押上筒５が落下する。When the push-up cylinder 5 rises further in this state, the valve portion 9 of the rod-shaped valve 15 is disengaged from the valve seat 13 of the magnet, the air inside the push-up cylinder 5 escapes, and the push-up cylinder 5 falls.

ここで棒状弁１５は抵抗が少ないため押上筒５の落下速
度より早く、この結果第１図ｄの状態となり押上筒５内
の空気が抜け低下してゆく。Here, since the rod-shaped valve 15 has less resistance, the fall speed is faster than that of the push-up tube 5, and as a result, the state shown in FIG.

棒状弁１５の落下は上浮上高さ調整板１６が棒状弁保持
具２１に当って停止し、押上筒５の落下は棒状弁１５の
弁部９まで低下し、ここでマグネットの弁座１３により
弁部９か磁着され閉塞して第１図ａの状態となり、再び
押上筒５内に空気が溜り、前記と同様の作動をくりかえ

The valve portion 9 is magnetized and closed, resulting in the state shown in FIG.

ここで流入室３内の汚水の水位が高いときは揚水筒１内
の水位も高く押上筒５の１ストローク当りの排水量が多
いが、このとき水位が高いため押上筒５内に溜る空気が
圧縮されながら押上筒５を浮上させることとなり、揚水
筒１内の水位が低いときにくらべて押上筒５の浮上速度
が遅くなるものである。Here, when the water level of the wastewater in the inflow chamber 3 is high, the water level in the pumping tube 1 is also high and the amount of displacement per one stroke of the lifting tube 5 is large, but at this time, because the water level is high, the air accumulated in the lifting tube 5 is compressed. As a result, the lifting tube 5 is floated while being lifted, and the floating speed of the lifting tube 5 is slower than when the water level in the water pumping tube 1 is low.

一方流入室３内の汚水の水位が低いときは揚水筒１内の
水位も低く押上筒５の１ストローク当りの排水量は少な
いが、水位が低いため押上筒５の浮上速度が速くなるも
のである。On the other hand, when the water level of the wastewater in the inflow chamber 3 is low, the water level in the pumping tube 1 is also low and the amount of displacement per stroke of the lifting tube 5 is small, but because the water level is low, the floating speed of the lifting tube 5 becomes faster. .

したがって流入室３内の水位に高低があっても一定量の
汚水を排水口２より排水できることとなる。Therefore, even if the water level in the inflow chamber 3 is high or low, a certain amount of wastewater can be drained from the drain port 2.

第２図は空気抜き装置７の他の実施例が示してあり、棒
状弁１５が押上筒５の上部の閉塞部よりも下方に位置し
ていて、棒状弁ガイド筒２２によってガイドされるよう
になっており、棒状弁ガイド筒２２の上端部に棒状弁保

この実施例にあっては棒状弁１５が揚水筒１より上方に
突出しないため邪魔になったりすることがなく、また棒
状弁１５が揚水筒１内の上部の汚水部分に接触しないた
め汚物がついたり腐蝕したりしないものである。In this embodiment, the rod-shaped valve 15 does not protrude above the pumping tube 1, so it does not get in the way, and since the rod-shaped valve 15 does not come into contact with the upper part of the sewage tube inside the pumping tube 1, filth cannot be collected. It does not corrode or corrode.

なお揚水筒１の下部に汚水よりも比重の重たい液体２０
がはいっているため弁部９によって弁座１３が閉塞され
ていない場合であっても汚水が弁座１３の孔１４から押
上筒５内に流入しないこととなる。In addition, a liquid 20 with a specific gravity heavier than sewage is placed at the bottom of the water pump 1.
is in place, so even if the valve seat 13 is not closed by the valve portion 9, dirty water will not flow into the push-up cylinder 5 through the hole 14 of the valve seat 13.

また第２図の実施例において弁部９をゴム栓にて形成し
てもよい。Further, in the embodiment shown in FIG. 2, the valve portion 9 may be formed of a rubber plug.

おそく、水位が低いときには押上筒の押上げ速度が速く
、この結果水位の高いときも低いときも一定量を排出で
きるという利点があり、しかも空気の浮力を利用して押
上筒を押上げるので少ない空気量で常に一定量の排出が
できるという利点がある。In the present invention, as described above, the lifting tube is floated by air sent from the air pipe provided at the bottom of the lifting tube, and at the maximum floating position of the lifting tube, the air inside the lifting tube is removed and the lifting tube is lifted up. Equipped with an air bleed device that lowers the tube downwards, and a flow rate adjustment means that adjusts the maximum floating position and maximum descending position of the push-up tube to adjust the flow rate. Not only can the water in the pumping cylinder be discharged from the drain port by pushing up the cylinder, but when the water level is high, the air is compressed and the lifting speed of the lifting cylinder is slow, and when the water level is low, the lifting cylinder is slow. The push-up speed is fast, which has the advantage of being able to discharge a constant amount regardless of whether the water level is high or low.Furthermore, since the buoyancy of the air is used to push up the push-up tube, a constant amount can always be discharged with a small amount of air. It has the advantage of being possible.
