20110204002 | Method and Device for Separation of a Loose Mixture in a Fluid Medium - Method of separation of loose mixture in fluid medium consists in the gravity feed of particles, aerodynamic monotonically increasing effect on them at acute angle to the vertical line by the cascade of slot jets and the outlet of separated fractions into separate collectors. Before aerodynamic effect on loose mixture particles each jet is transferred to developed turbulence mode by their vertical expansion jets until jets are merged with each other with faulty or close to it form of jet formation and the appearance of at least two circulation zones different in size in each inter-jet space of all contiguous jets. The device for separation contains the bunker with vibrating chute mounted underneath the jet generator, the flat nozzles located one under another at acute angle to the vertical line, the height of cross sections of which, step and angle of installation increase top-down. The generator is connected with the source of air supply under pressure, and is covered by the side walls, and grade collectors. Each nozzle is equipped with rectangular rigid wall adjoined to its top across full width of the nozzle. The size of the rigid wall width makes at least three dimensions of cross-sectional height of the nozzle contiguity, and the ratio of installation step of nozzles to the height of cross section of the upper nozzle in relation to it is not less than four. | 08-25-2011 |
