[0002] Titanium, with its low density, high strength, and corrosion resistance, is widely used in aerospace, machinery manufacturing, defense, military, and biomedicine. Titanium powder is a key raw material for titanium and titanium alloy powder metallurgy, and the dehydrogenation of titanium hydride powder is a key step in the hydrogenation and dehydrogenation process used to produce low-cost titanium powder.

[0003] In related technologies, the most commonly used dehydrogenation method is the loose powder dehydrogenation method. Under vacuum conditions, after reaching a certain temperature, the hydrogen atoms in TiHx are desorbed and diffuse through the TiHx layer through mechanisms such as atomic penetration, eventually completing the dehydrogenation and obtaining titanium powder.

[0004] Regarding the above-mentioned related technologies, the dehydrogenation of titanium hydride powder is an endothermic reaction. The finer the powder, the easier it is to agglomerate and sinter, resulting in irregular shape and poor fluidity of the titanium powder, so it needs to be improved. Summary of the Invention

In addition, the airflow generated by the blower hinders the materials that meet the specifications, realizes the rapid screening of materials that meet the specifications and materials that do not meet the specifications, reduces the flow of materials toward the docking port, and drives the materials that meet the specifications inside the shell to quickly settle into the collection box.

[0024] Secondly, The present application provides a method for using a hydrogenation and dehydrogenation device for preparing powder for smart products, comprising the following steps: Feeding: The feeding component transports the coagulated materials into the grinding component; Grinding: The grinding component grinds the aggregated materials and sieves the materials that meet the specifications into the aggregate box; Return material: The transfer component transfers the material that does not meet the specifications to the feeding component for repeated grinding; Discharging: Remove the aggregate box to take out the material that meets the specifications.

[0049] The implementation principle of the hydrogenation and dehydrogenation equipment for preparing powder for smart products in the embodiment of the present application is as follows: The material is fed into the feed barrel 31 through the feed hopper 32.

The ground material passes through the grinding drum 21 and falls into the screening drum 41. Substandard material remains between the grinding drum 21 and the screening drum 41. As the centrifugal force generated by the rotation of the screening drum 41 follows the rotation of the grinding drum 21, it gradually passes through the docking port 12, which is connected to the passage 412. It then moves through the transfer tube 42 into the feed hopper 32, where it can be re-entered into the grinding drum 21 through the feeding assembly 3 for graded grinding.

[0051] Finally, the materials that meet the specifications pass through the screening holes 411 of the screening cylinder 41 and fall into the collecting box 11 to achieve rapid collection of the materials, thereby refining the particle size of the titanium powder and improving the fluidity of the titanium powder, thereby improving the quality of the titanium powder product.
