BULK MIXTURE SEPARATION APPARATUS Russian patent published in 1999 - IPC

FIELD: agriculture, food-processing, chemical and other branches of industry, in particular, air separation of bulk materials. SUBSTANCE: apparatus for separating bulk material in liquid flow has hopper with gate, vibration chute positioned under hopper and provided with orienting troughs, vibration chute driving mechanism, air flow supply nozzle with supply system, inclined surface, and ready fraction collectors. Nozzles are mounted at trough ends at an angle to vibration chute and rigidly connected with it so as to define single inclined surface continuing trough bottom surfaces. Length of this surface is half the maximum length of separated particles. Nozzle supply system has setter and pressure stabilizer made in the form of double-membrane four-chamber pneumatic member with channel for releasing excessive pressure into atmosphere. EFFECT: increased efficiency by increased precision in separating bulk material into fractions by weight and density. 3 dwg
