ならざるを得なかつた。(b) Conventional technology and its problems A conventional screw decanter type centrifugal concentrator introduces a suspension from one shaft of a rotating bowl, and creates a pool in the bowl by the centrifugal force that accompanies the rotation of the bowl. The suspended solid particles are separated by sedimentation in the pool, and the supernatant liquid is discharged outside the machine over a liquid outflow weir set at one end of the bowl, and the sedimented particle accumulation liquid, that is, the concentrated liquid, is sent to the screen. Carry it to the other end of the bowl with Yukon Bear,
It is scraped and discharged from the conical end, or in a nozzle discharge type concentrator, it is discharged from a nozzle provided at the cylindrical end of the bowl. Therefore, since the separation product discharge site of conventional centrifugal concentrators is located at or near the outer periphery of the bowl, the circumferential velocity of the effluent is high, and the effluent is discharged with large kinetic energy, resulting in low consumption. The power is great. Furthermore, as the bowl rotates, power loss due to the flow action that occurs at the openings and protrusions of the bowl and bowl housing cannot be avoided, which causes a large energy loss in the conventional device. The differential mechanism with the conveyor had to be large as well.

来型は種々の不都合な問題を有していた。 Furthermore, in conventional centrifugal concentrators, the factors related to the concentration of concentrate are the pool depth (height of the weir), the difference in rotation between the bowl and the screw conveyor, and the nozzle diameter. If you want to adjust the concentration, in the case of a weir, it can only be done by a concentrator with special additional equipment, such as changing the nozzle diameter,
Processes such as nozzle blockage cannot be carried out without stopping the liquid supply and the rotation of the concentrator itself, and the conventional type has various disadvantages.

(ト) 発明の効果
遠心濃縮機の消費動力は重力による位置のエネ
ルギーと供給液の運動エネルギーを無視すると、
一般に次式で与えられる。(g) Effects of the invention The power consumption of a centrifugal concentrator is as follows, ignoring the potential energy due to gravity and the kinetic energy of the feed liquid.
Generally, it is given by the following formula.
Ｐ＝Po＋（１＋η）（Q1E2＋Q2E2）
ここにＰは全消費動力、Poは無負荷即ち供給
停止時の動力、Q1は濃縮液排出量、E1は同液の
もつ運動エネルギー、Q2は分離液排出量、E2は
同液のもつ運動エネルギー、ηは内部損失係数で
ある。 P = Po + (1 + η) (Q 1 E 2 + Q 2 E 2 ) Here, P is the total power consumption, Po is the power when there is no load, that is, the supply is stopped, Q 1 is the concentrated liquid discharge amount, and E 1 is the amount of the concentrated liquid The kinetic energy, Q 2 is the amount of separated liquid discharged, E 2 is the kinetic energy of the same liquid, and η is the internal loss coefficient.
この式からQ1Q2を一定とすると、各液の排出
の運動エネルギーE1E2が小のとき全消費動力は
小さくなる。排出液の運動エネルギーは排出点の
周速度の２乗に比例する。本発明の装置では従来

作用もない。又ボウルの外側のハウジング２５は
完全密閉であるので流動空気の逸散を完全に防ぐ
ことができ、流動空気の逸散による動力損失も起
らない。 From this equation, assuming that Q 1 Q 2 is constant, the total power consumption will be small when the kinetic energy E 1 E 2 of discharging each liquid is small. The kinetic energy of the discharged liquid is proportional to the square of the circumferential velocity at the discharge point. In the device of the present invention, the discharge position is closer to the axis of the rotating shaft than in the conventional device, so the kinetic energy is small and the power consumption is very small. Further, since the device of the present invention has no protrusions on the side wall and outer peripheral wall of the bowl and no openings in the casing, and is simply smooth, air resistance is small and there is no blower action. Furthermore, since the housing 25 outside the bowl is completely sealed, it is possible to completely prevent the flowing air from escaping, and no power loss occurs due to the escaping of the flowing air.
