METHOD AND UNIT FOR SEPARATING PARTICLES IN A FLOW Russian patent published in 2021 - IPC B07B13/11 

FIELD: separating solids from solids.

SUBSTANCE: group of inventions relates to separation of particles, in particular, seeds. In implementation of the method, multiple particles are supplied to the supply pipeline, the rotating body is rotated around the axis. The body forms at least one channel extending from the inner end adjacent to the axis on the outside to the outer end located at a greater radial distance from the axis outward than the inner end. Multiple particles are supplied into the inner end of the channel, located in the array near the axis, so that the supply pipeline acts to deposit the particles at the inner end of the channel to introduce the particles into the inner end and to separate the flow of particles in the pipeline into a separate channel. The body is rotated at an angular velocity creating a centrifugal force on the particles, wherein said force overcomes the friction of the particles caused by the contact of the particles with the channel, thus causing the particles to accelerate while passing from the inner end to the outer end, and ensuring separation of the particles so that the particles would be separated from each other by space by means of acceleration caused by the centrifugal force in the channel and aligned in a row one after another in the channel in the course of movement thereof towards the outer end.

EFFECT: speed of particle separation is increased, dimensions of the equipment are decreased, power consumption is reduced.
