AI Technical Summary

Technical Problem

Existing vacuum heat reduction smelting metal equipment cannot effectively process the generated gas during the heating process, causing the metal vapor to react with water vapor and oxygen, reducing the purity of the metal.

Method used

A vacuum thermal reduction and smelting metal equipment is designed, which adopts two stages of vacuum heating, and isolating metal steam from other gases through the cooperation of the opening and closing pipes and the absorption pump, and finally condenses the metal in the condensation device to obtain high-purity metal.

Benefits of technology

The orderly separation of metal steam and other gases is achieved, the purity of metal is improved, the safety of smelting and product quality is ensured, and the reaction condensation and collection are allowed to be independent, which is convenient for detection and equipment maintenance.
