METHOD FOR PNEUMATIC UNLOADING OF HARDLY LOOSE OXIDANT Russian patent published in 2008 - IPC B65G53/28 

FIELD: technological processes.

SUBSTANCE: invention is related to pneumatic unloading of loose material, in particular, hardly loose oxidant, for its further pneumatic transport, may be used in different industries. Method includes supply of compressed air, preparation of aeromixture, its transport with suction vacuum pump, settling in unloader and capture of particles with wet filter. For method realisation inclined drum is used for prearation and unloading of aeromixture. Aeromixture is formed in it by supply of compressed air with pressure of up to 0.07 MPa and with continuous motion of oxidant together with cylindrical elements with diameter and height of 30-40 mm from elastic polymer materials. At that oscillatory motion of drum is created with amplitude of up to 180° at the same angle of travel from vertical axis. For aeromixture removal from drum in the beginning of drum oscillatory motion, unloading hatch gate is remotely opened, aeromixture is transported to material line along flexible sleeve connected to unloading hatch. Mass ratio of oxidant and cylindrical elements prior to unloading beginning is taken as accordingly 1:0.15-0.3.

EFFECT: provides more complete unloading of oxidant from reservoir for its further pneumatic transport.
