SOLVENT APPARATUS WITH A STIRRING DEVICE Russian patent published in 2020 - IPC B01F1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to devices for chemical reaction of solid and liquid phases and can be used for leaching, dissolution in metallurgy, chemical and other industries, in particular, when working with radioactive materials. Dissolvent device comprises a vertical cylindrical housing with process pipes installed on the cover for supply and removal of solvent and dissolution products, inlet of air or inert gas and instrumentation, heater mounted outside the housing, on the cover of the housing there is an agitator drive of the mixing device, which is located in the lower detachable part of the apparatus, consisting of a pressure cylindrical tray with a hollow cup coaxially installed in it. Stirring device is made with possibility of vertical reciprocating movement, and the lower detachable part is made with possibility of vertical movement.

EFFECT: high efficiency of the dissolution process owing to passive initial mixing and subsequent efficient mixing.
