DEVICE FOR CONTINUOUS IODINE EXTRACTION FROM SOIL AND ITS CONCENTRATION IN INTENDED VOLUME Russian patent published in 2008 - IPC C01B7/14 G01N33/24 

FIELD: transportation; mining engineering.

SUBSTANCE: device contains vertical pipe 1 with heated center part provided with inlet 11 and outlet 12 openings for air flow passing, side cutting 13 located under outlet openings 12 and side segment 14 with outlet fitting15. Side segment 14 closes with clearance the outlet openings 12 and side cutting 13. Outlet fitting of side segment 14 is connected with remote reservoir 23 in the upper part of which aerosol 2 and sorbtion 3 filters are located which are isolated from ambient medium by cover 4 connected via rotameter 24 with exhaust pump 6 through exhaust fitting 5. On bottom end of vertical pipe 1 outlet 18 and adjusting 19 discs are located as well as sectional knife 21 connected with electric motor 17 shaft via conveyer screw 22. In the top part of vertical pipe 1 receiving cone 16 and electric motor 17 are located. Main electric heating element 8 is located outside the middle part of vertical pipe 1 and is covered by heat insulator 9. Auxiliary electric heating element 25 is located under remote reservoir 23 partially covered with heat insulator 9 to the side surface of which the striking element is attached.

EFFECT: labour content reduction; increase in process efficiency and providing the possibility of continuous iodine extraction from unlimited soil quantity.
