FEEDING DEVICE FOR PARTICLES SEPARATOR, SEPARATOR FOR PARTICLES SEPARATION AND METHOD OF PARTICLES SEPARATION Russian patent published in 2020 - IPC B03B11/00 B03B5/62 

FIELD: separation.

SUBSTANCE: disclosed group of inventions relates to a particle separator feed device, and in particular to a particle separator feed device for suspensions, containing particles with low and high density and/or particles of different sizes. This invention has been developed mainly for use as separator for separation of particles from mineral suspensions, containing low-density particles and/or smaller particles and high-density particles and/or larger particles; further, it will be described with reference to this application. Device for feeding loaded suspension into separator for particles includes chamber, having at least one partition for separation of chamber into first zone and second zone, fluidization source for supply of liquefying fluid medium into baffle hole and raw material inlet for supply of suspension into first zone, where the partition removes the suspension from the second zone and directs the liquefying fluid from the fluidization source through the second zone for integration with the suspension from the first zone. Second zone is formed inside partition, and first zone is formed between partition wall outer side and chamber. Baffle opening has inner diameter substantially equal to fluidizer source inner diameter. Feeder is used to implement method of feeding suspension into separator, including separation of chamber into first zone and second zone by partition, wherein the second area is formed inside the partition, and the first zone is formed between the outer side of the partition and the camera; feeding suspension into first zone; removal of suspension from second zone; and feeding fluidizing fluid from the fluidisation source to the baffle opening and through the second zone to create a liquefying flow which is combined with the suspension from the first zone. Loading device for loaded suspension is used in device for separation of particles with low density and/or smaller size of loaded suspensions, including a plurality of inclined channels located near the first end of the chamber, and in which the fluidization source is located near the second end of the chamber.

EFFECT: technical result is reduction of amount of fluidizing medium, as well as high efficiency of separation from suspension of particles with low density and/or smaller size.
