The invention belongs to the technical field of hydrogen treatment of rare earth permanent magnets or hydrogen absorbing materials and particularly relates to an intermittent type continuous hydrogen treatment method of rare earth permanent magnets. In the dehydrogenation procedure, powder materials enter a rotary furnace pipe of a dehydrogenation furnace through rotation of a spiral material supplying device and are heated and dehydrogenized in vacuum. After the dehydrogenation procedure is ended, through reverse rotation of the rotary furnace pipe of the dehydrogenation furnace and the spiral material supplying device, the dehydrogenized powder materials fall into an inlet of a spiral feeding device of a cooler on the lower side, the spiral feeding device rotates, and the dehydrogenized powder materials are pushed into the cooler and cooled. A dehydrogenization section always conducts heating dehydrogenization, and a cooling section always conducts cooling. Because heating dehydrogenization and cooling are conducted in the rotary furnace pipe and the cooler correspondingly, thermal fatigue caused when the same furnace pipe conducts heating and cooling is avoided.
