Vacuum induction distillation furnace

Abstract

The invention relates to the technical field of distillation furnaces, in particular to a vacuum induction distillation furnace. The furnace comprises a base and a furnace body, the furnace body is arranged on the base, a crucible and a condensation cover are arranged in the furnace body, the condensation cover covers the open end of the crucible, the furnace body is a vacuum furnace, a high-frequency induction coil is arranged around the crucible, the high-frequency induction coil is connected with an electrode interface extending out of the furnace body, the condensation cover adopts a watercooling mode, a thermocouple is arranged on the condensation cover, one end of the thermocouple extends into the condensation cover and is connected with the condensation cover, the other end of thethermocouple extends out of the furnace body and is connected with the furnace body, the furnace body comprises a furnace cover and a furnace stack, the furnace stack is in sliding fit with the base,the furnace cover is fixedly connected to the base, the crucible is connected with the furnace cover, the condensation cover is connected with the furnace stack, a control part is arranged on the base, the control part adopts a mode of combining PLC control, operation buttons and an operation interface, and an electric control box is arranged on one side of the base. According to the furnace, by arranging the crucible subject to induction heating by the high-frequency coil, the furnace cover capable of being opened in a sliding mode and the condensation cover capable of being lifted, the separation and purification on rare metal are achieved in a vacuum environment, and the purification effect is good.

Description

technical field [0001] The invention relates to the technical field of distillation furnaces, in particular to vacuum induction distillation furnaces. Background technique [0002] Most of the metal elements we need in our daily production and life come from ore smelting. The composition of the ore is relatively complex, and most of the metals smelted are alloys of various mixed components, which do not meet our normal production and living needs. Therefore, it is necessary to separate and decompose these complex alloys into the high-purity metal elements we need, especially the purification of some rare and precious metals such as gold, silver, palladium, platinum, etc. These metals have high value and large demand, but are difficult to purify. The cost is high and the output is low. [0003] At present, the main methods of separation and purification of these rare metals are: chemical method, ion exchange method and solvent extraction method. However, these methods not ...

Problems solved by technology

However, these methods not only use a large amount of chemical reagents such as nitric acid, oxalic acid, and aqua regia in production, but also react slowly when strong acids dissolve and precipitate metals, resulting in low yield, slow speed, long cycle, high cost, and great environmental pollution.
