Description

Technical Field

[0001] The utility model relates to the technical field of metal chromium smelting equipment, in particular to a metal chromium smelting mixing device. Background Art

[0002] Metallic chromium is usually used to smelt high-temperature alloys, resistance alloys, precision alloys and other non-ferrous alloys. With the advancement of science and technology, the role of high-quality metallic chromium is becoming increasingly important. The production methods of metallic chromium include electrosilicon thermal method, aluminothermic method, electrolytic method, etc. The electrosilicon thermal method has been eliminated long ago because the silicon content in the alloy is greater than 2%. As the importance of pure chromium continues to increase, the demand for the electrolytic method to produce metallic chromium is increasing. The aluminothermic method uses chromium trioxide as a raw material and aluminum powder as a reducing agent to produce metallic chromium. Due to its simple production process, low equipment investment, small footprint and high alloy quality, it has always been a widely adopted production method. In the prior art, no matter which method is used to prepare metallic chromium, the mixing process used in the front-end process plays a very important role in the smelting of metallic chromium. The mixing device currently used does not mix the front-end materials evenly enough, resulting in the production of metallic chromium of low purity, so it needs to be improved;

[0003] After searching, the China Patent Network discloses a high-efficiency mixing device for metal chromium smelting, and its authorization announcement number is CN209679909U. The patent adopts a structure of multiple mixing units, which can achieve uniform mixing of multiple materials. First, the materials to be mixed are added to multiple bowl-shaped containing blades from multiple feeding ports. Through the rotation of the first rotating motor, the materials in the multiple bowl-shaped containing blades are centrifugally thrown out for the first mixing. Then, through the rotation of the second rotating motor, the multiple stirring blades are driven to mix the materials for the second time. Finally, through the rotation of the third rotating motor, the circular material plate is driven to mix the materials for the third time, which can achieve uniform mixing of multiple materials.

[0004] However, the patent has a slow material discharge speed after mixing, and it is not easy to quickly discharge the metal chromium after mixing, which affects the production efficiency and has defects in use.
