PARTICLE SEPARATION SYSTEM Russian patent published in 2018 - IPC B03C1/12 B03C1/247 B03C1/28 

FIELD: separation.

SUBSTANCE: disclosed group of inventions relates to a separator and a system for separating particles, configured to remove magnetic and nonmagnetic conductive particles from a liquid. It can be used to remove ferrous particles and non-ferrous particles from phosphate coating and electrophoretic coating systems used in the manufacture and assembly of car bodies. Particle separator comprises a housing, a rotor mounted inside the housing and having a plurality of electromagnets arranged with alternating poles, and a valve configured to flush magnetic and non-magnetic conductive particles from the housing near a collection area. Rotation of the rotor and supply of current to the electromagnets generates an alternating magnetic field and eddy currents in nonmagnetic conductive particles in a liquid coating flowing through the housing. Nonmagnetic conductive particles are repelled in the direction of flow of the coating towards the collection area in the housing by means of a magnetic field. Magnetic particles in the coating stick to electromagnets, to which current is applied, and are directed to the collection area by de-energising the electromagnets. System for separating particles comprises an immersion tank containing a liquid coating, a housing, a particle separator located in the housing and having a plurality of electromagnets with alternating poles, a torque source configured to rotate the particle separator to generate an alternating magnetic field, and a valve for flushing non-magnetic conductive and magnetic particles from the housing near the collection area. Liquid coating flows into the housing from the immersion tank through a first channel, magnetic particles in the liquid coating are attached to a plurality of electromagnets. Alternating magnetic field generates eddy currents in nonmagnetic conductive particles in the liquid coating. Nonmagnetic conductive particles are repelled under the action of an alternating magnetic field from along the flow of the liquid coating towards the collection area in the housing. Magnetic particles attached to the plurality of electromagnets are sent to the collection area during de-energising of the electromagnets. Liquid coating is returned to the immersion tank through a second channel. Liquid coating is a phosphate coating or an electrophoretic coating.

EFFECT: technical result is higher efficiency of separation.
