Patent ID: 8137612

Claim:
An apparatus for continuously manufacturing stoichiometric Mg 2 Ni hydrogen storage compound, comprising: a vacuum chamber filled with an inert gas; a first crucible, set in the vacuum chamber, for holding a raw material of magnesium; a heating device, surrounding the first crucible, for heating the first crucible loaded with the raw material of magnesium and melting the raw material of magnesium to a magnesium liquid; a material feeding tube, set in the vacuum chamber, for adding nickel powders to the first crucible loaded with the magnesium liquid; a stirring device, set in the vacuum chamber and above the first crucible, for stirring the magnesium liquid to make the nickel powders fast melt in the magnesium liquid; a hoist mechanism, set in the vacuum chamber for hanging the first crucible into or out of the heating device; and a second crucible, set in the vacuum chamber, and on one side of the first crucible, wherein the heating device is further used for heating the first crucible loaded with a mixture of the nickel powders and the magnesium liquid to produce a magnesium-nickel liquid and controlling the heating temperature of the heating device to fall within a temperature range; a stoichiometric Mg 2 Ni hydrogen storage compound is precipitated from the magnesium-nickel liquid; a residual liquid in the first crucible is separated from the precipitated stoichiometric Mg 2 Ni hydrogen storage compound and poured from the first crucible to the second crucible; and the stoichiometric Mg 2 Ni hydrogen storage compound in the first crucible is cooled and drawn out from the first crucible after cooling.
