DEVICE TO SEPARATE MIXTURES AND ALLOYS Russian patent published in 2008 - IPC C22B9/04 F27B14/06 B01D3/10 

FIELD: metallurgy.

SUBSTANCE: invention concerns device able to separate various mixtures and alloys by splitting them into compositional fractions; specifically, for procurement of high-purity metals - up to 99.99 % by application of the vacuum distillation method. The device made to separate mixtures and alloys by the said vacuum distillation method contains therein vacuum chamber equipped with a pumping facility, inductor to heat up the cup with an initial material, condensator installed in a coaxial relationship over the inductor, the high frequency, water-cooled coaxial current feedthrough, and cup. The latter is designed in the shape of a glass made from the thermal isolated material installed in an axial alignment with both the inductor and the condensator; it is turned with its frontal side towards the latter and has, round its open side, a horizontal section. The high frequency water-cooled coaxial feedthrough is passed through the vacuum chamber wall and has an internal wire unit used to conduct high pressure, and an external one to introduce the zero potential which, in turn, is electrically linked with the vacuum chamber body. The cup surrounds the condensator from the side opposite to that facing the glass and has an internal diameter whose size is more than the external diameter of the condensator, whereas its exterior diameter is less than that of the edge of the glass' open side, and connects with the pump. The inductor is made in the shape of a spool which encompasses the glass and has a number of convolutions. There are more than two and their upper and lower ones are both interlocked and electrically connected with, respectively, the external and internal wires of the high frequency coaxial water-cooled feedthrough. The condensator is located up above the glass' open side and has an external diameter whose size is larger than that of the glass. The condensator and the cup which surrounds it can be both installed with an opportunity of being moved along the vertical and horizontal axes. The high frequency water-cooled coaxial feedthrough and the inductor may also be installed with an opportunity of being turned all around the horizontal axis of the feedthrough. The technical effect is comprised of eradication of the charge occurrences that might happen under conditions of high pressure and voltage. That illustrates advantages of an inductive heating procedure coupled with the vacuum distillation accomplishments. First and foremost, all users will be able to conduct the fusion processes while working with the highly volatile metals, increase productivity of operation and achieve drastic reductions in the metal losses.

EFFECT: opportunity of fusing the highly volatile metals complimented with reductions in the metal losses and substantial increases in productivity of work.
