る。 When a liquid to be classified containing fine particles of various sizes is to be treated, the rotating device 23 is first activated to rotate the closed container 1 and the intermediate body 10 integrally, and the liquid to be classified is introduced into the inflow path 15. When the liquid for taking out the classified product is supplied to the inflow path 14, the liquid to be classified flows from the inflow path 15 into the upper gap 16 in the closed container 1, and in the gap 16, the liquid to be classified flows into the closed container 1.
The flow is regulated to a stable laminar flow due to viscous resistance when it comes into contact with each surface of the plate body 12 , and is expanded into a spiral shape in a plan view due to centrifugal force and is supplied to the separation space 7 . The particles flowing in the space 7 are parallel to the liquid for removing the classified material supplied from the inflow path 14, and the mixed particles in the liquid to be classified are blown outward according to the size of the particles by centrifugal force, and the liquid for removing the classified material is flown. The particles are separated into the liquid for taking out the classified material introduced from the inlet 13 through the inflow path 14, and only fine particles with a certain particle size or less flow into the lower gap 20 together with the liquid to be classified, and are continuously fed from the inflow path 15. Due to the pressure of the liquid to be classified, the liquid flowing into the lower gap 20 is directed toward the classified liquid outflow path 22 located at the center of the closed container 1 and is taken out. On the other hand, particles larger than a certain particle size are separated into the liquid for taking out the classified material in the separation space 7, and the pressure of the liquid for taking out the classified material, which is also continuously fed from the inflow path 14, causes the particles to reach the outlet 19.
It is sent out to the outflow path 21 and taken out of the device.

The liquid to be classified flows into the separation space 7 in a laminar and spiral manner, and at the same time, the liquid for taking out the classified substance is located outside the liquid to be classified and flows in from the inlet 13 from the inflow path 14, so that the liquid to be classified flows. The flow is extremely smooth and rectified, creating a smooth flow suitable for classifying even large and small mixed particles, making highly accurate classification possible. That is, the liquid to be classified that has flowed into the separation space 7 in a laminar flow maintains a stable laminar flow because the closed container 1 and the intermediate body 10 are rotating integrally, and flows into the lower gap 20.
During this time, the larger the particle size of the mixed particles is blown into the liquid for removing the classified material in the separation space 7 due to centrifugal force, and only fine particles with a certain size or less pass through the separation space 7. Lower gap = 2
It flows into 0 and is classified.

高能率の連続分級が可能となつたのである。 As described above, in order to perform highly accurate classification of fine particles, the present invention mixes fine particles to be classified into a liquid to create a liquid to be classified, and forms the liquid between the closed container 1 and the intermediate body 10. The liquid to be classified is made to flow through the gap 16 to form a well-organized laminar flow, and a liquid for taking out the classified material is arranged outside the liquid to be classified, and the entire sealed container 1 is rotated to take out the liquid to be classified and the classified material. This is a device that applies centrifugal force to the liquid used to classify fine particles.This makes it possible to obtain products with higher precision and better quality in various ultra-precision machining processes that utilize extremely small particles. It became possible. The liquid to be classified and the liquid for taking out the classified product flow in from separate inlets, and the liquid to be classified is rectified into stratified fluid from around the shaft of the intermediate body by the same plane and viscous resistance, and spreads into the liquid for removing the classified product at the outer periphery. , from the periphery of the intermediate to the periphery of the closed container due to the centrifugal force depending on its viscosity, and the large particles are dispersed in an orderly manner far away and the small particles are nearby. The falling direct current of the liquid for taking out the classified material causes it to settle to the bottom of the closed container in a substantially parallel flow, so that the eddy current caused by the reversed flow that occurs near the inner surface of the closed container when it is scattered from the intermediate is not generated by this falling direct current, and the liquid flows mutually. There is no local retention in the vicinity,
In a stable sedimentation state, it descends and is discharged from the outlet, and since the fine particles are sufficiently rectified by liquid layer on the upper surface of the intermediate body than the outer periphery of the shaft body, scattering due to centrifugal force can also be dispersed far away. Therefore, there is no disturbance in the fine particle region, and there is no mutual diffusion with the coarse particle region, so that the liquid reaches the lower plate and is discharged from the outflow path of the liquid to be classified. The present invention is a two-liquid type with double inlets and inlets, which allows each flow rate to be adjusted, making it extremely easy to set the classification size by adjusting the flow rate and the rotation speed of the sealed container, and achieving high precision. Highly efficient continuous classification has become possible.
