Description

Technical Field

[0001] The utility model relates to the technical field of tantalum niobium preparation, in particular to an oxygen reduction device for tantalum niobium powder. Background Art

[0002] Tantalum niobium powder deoxygenation equipment is mainly used to reduce the oxygen content in tantalum niobium powder to improve its quality and performance. This device usually involves a series of processes and equipment to ensure the effective removal of oxygen in the powder;

This technology discloses "a device and method for reducing oxygen and evacuating tantalum powder and absorbing magnesium powder and carbon vapor. The device for reducing oxygen and evacuating tantalum powder and absorbing magnesium powder and carbon vapor includes a first main tank, a second main tank, a first exhaust pipe and a second exhaust pipe" and other technical solutions, with "a stainless steel ball is set in the main tank to absorb high-temperature magnesium vapor, and the activated carbon is wrapped with a stainless steel mesh to absorb magnesium powder and carbon vapor in the process of exhausting magnesium" and other technical effects;

[0004] The deoxidation process of tantalum-niobium powder is usually carried out in a specific vacuum reactor. However, due to the inevitable existence of gaps and accumulation between powder particles, the release of oxygen inside the powder may be uneven. To complicate matters, during the heating process, those areas close to the heating source or with excellent thermal conductivity tend to have higher temperatures, while areas far from the heating source or with denser accumulation may have lower temperatures. This uneven temperature distribution will undoubtedly have a significant impact on the deoxidation effect and the final quality of the powder. Utility Model Content

[0034] In this embodiment, the output end of the first motor 232 drives the active pulley 233 to cooperate with the belt 234 to drive the driven pulley 231 to rotate. The driven pulley 231 drives the outer cylinder 211 to rotate through the connecting head 212. The outer cylinder 211 drives the tantalum-niobium powder inside the inner cylinder 221 to roll continuously, thereby increasing the contact area with the inert gas, promoting the release of oxygen, and making it heat evenly, thereby improving the oxygen reduction efficiency.
