Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production by hydrolysis, and particularly relates to a feeding mechanism for hydrogen production by hydrolyzing aluminum. Background Art

[0002] The technology of hydrogen production by hydrolyzing aluminum is a hydrogen production method based on the chemical reaction mechanism between aluminum and water. As a metal element with a huge reserve in the earth's crust, aluminum has significant potential for hydrogen production. The economy and environmental friendliness of this technology lie in that through the recycling and reprocessing of aluminum materials, not only the cost is effectively controlled, but also the dependence on raw resources is reduced, thus promoting the sustainable development of hydrogen production;

[0003] In the prior art, since the oxide film formed on the surface of aluminum will prevent it from contacting with water, a ball mill is usually used to reduce this influence. However, during the process of transferring aluminum from the ball mill to the reaction tank, the irregular shape of aluminum and the restriction of the tortuous pipeline may lead to unsmooth transportation and the contact of aluminum with oxygen in the air, causing the aluminum surface to oxidize again, thereby affecting the subsequent hydrolysis reaction. Therefore, the present application provides a feeding mechanism for hydrogen production by hydrolyzing aluminum. Summary of the Utility Model

[0004] In order to solve the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a feeding mechanism for hydrogen production by hydrolyzing aluminum, which can ensure the smooth input of aluminum materials into the reaction tank, and on this basis, optimize the contact conditions between aluminum materials and water, and significantly improve the overall efficiency of hydrogen production by the hydrolysis method.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:
