Description

Technical Field

[0001] The utility model belongs to the technical field of mining equipment, and in particular relates to a gas-based full-granularity anti-oxidation device for powdered ore. Background Art

[0002] Antioxidation is a crucial component of many industrial processes, particularly in metal processing and chemical raw material preparation. Under high-temperature conditions, materials easily react with oxygen in the air, leading to performance degradation or even failure. Therefore, developing effective antioxidant technologies is crucial for ensuring product quality and extending product life. Traditional antioxidant methods include the use of antioxidants, vacuum treatment, and inert gas protection. Nitrogen, due to its stable chemical properties and resistance to reaction with other substances, has become a widely used inert gas.

[0003] Existing technology usually uses nitrogen to quickly blow the materials that need to be antioxidant into water. However, when the powdered ore is at high temperature, it will stir up a lot of dust when it comes into contact with water. This will not only cause environmental pollution, but also easily lead to safety accidents and cause great loss of metal resources. Utility Model Content
