中に放出される。 Water is drawn from the spout pipe 7 in the direction of the arrow by the rotation of an impeller 5 driven by a submersible electric motor (not shown) built into the guide tube 3 . Due to the synergistic effect (effect) of this suction force and the negative pressure caused by the flow rate of water passing around the outer periphery of the umbrella-shaped air outlet 10 provided at the tip of the air introduction pipe 9 in the spout pipe 7, air is sucked and the blades The rotational force of the wheel 5 mixes the gas and liquid and breaks them into fine particles, and the tip of the baffle plate 6 increases the Ray nozzle number of the water, creating a strong vortex, shearing the air bubbles and making them fine. The above-mentioned gas-liquid mixture is pressurized on the discharge side due to the rotation of the impeller 5, and further includes a rectifier plate 4 which also serves as a mounting plate,
The discharge pipe 1 is flowed while being rectified by the rectifying plate 13 (preventing pressure loss due to swirling flow and preventing gas-liquid separation).
2 and is discharged into water in a water tank (not shown) that communicates with a discharge pipe.
空気導入管１１の上部に設ける空気抵抗装置

好ましい。 The air resistance device installed at the upper part of the air introduction pipe 11 is composed of two regulating valves (primary and secondary), and the primary regulating valve 11' adjusts the amount of air required for intake into the aeration shaft. It is a cock valve that adjusts the opening degree according to the water depth of the flow aerator, and it is preferable that the inside of the cock valve be chamfered in order to reduce the swirling loss of air as much as possible.
第２次調整弁は第２図に示すように、キノコ弁

必要な開口部２２が数個設けられており、定状で

またばね２３の反撥力は微調整ねじ２４によつて
調整される。 As shown in Fig. 2, the secondary regulating valve has several openings 22 necessary for the intake air amount even when the mushroom valve body 21 is adhered to the valve seat, and in its normal state it has a small spring. It is separated from the valve seat by 23.
Further, the repulsive force of the spring 23 is adjusted by a fine adjustment screw 24.
２個の調整弁を設けた理由は、第１次調整弁で
絞られた圧力と吸入側圧力との差圧に対して僅に

る。 The reason for providing two regulating valves is that the secondary regulating valve opens slightly in response to the differential pressure between the pressure throttled by the primary regulating valve and the suction side pressure. This is because it is possible to prevent repetition of water flow fluctuations and air inflow fluctuations. That is, when the amount of water (liquid) sucked increases, the suction lift (negative pressure) suddenly increases, and a large amount of air is sucked into the air introduction pipe 11. If you try to suck in a large amount of air, the air flow speed will increase, and the suction resistance will be proportional to the square of the air resistance to the liquid velocity. To adjust this, several stages of low-resistance devices will be needed to remove excess air. By adjusting the air at the beginning of operation, the aeration system can be operated stably thereafter.
この発明は前記構成により以下の効果を生ずる
ものである。 The present invention has the following effects due to the above configuration.
(1) プロペラ型（羽根車型）軸流ポンプを使用す

な渦流を生起されるので、これにより気泡は剪
断及び微細化され、水中への酸素溶解を効果的
に行うことができる。(2) A strong vortex is generated in the gas-liquid mixture by the tip of the baffle plate, which shears the air bubbles and makes them finer, thereby effectively dissolving oxygen into the water.

共に気液の分離を起すことがない。(3) Current plates installed in several stages, i.e. current plates 6 and 13
In addition, the rectifying plate 4 which also serves as a mounting plate reduces the loss of water supply energy due to the swirling flow of the gas-liquid mixture, thereby significantly reducing the driving power and preventing separation of gas and liquid.
