Detailed Implementation

[0025] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 In this first embodiment, a dehydrogenation control device for neodymium iron boron magnetic materials includes...

[0027] Dehydrogenation furnace body 10;

[0028] The cover 20 is fitted onto the outer wall of the opening end of the dehydrogenation furnace body 10, and is connected to the dehydrogenation furnace body 10 by the connecting assembly 40.

[0029] The cover 20 has an inlet and outlet 31 on its side wall, and a door 30 is hinged to the inlet and outlet 31.

[0030] The movable plate 50 is movably installed inside the cover 20;

[0031] A stopper plate 51 is disposed on a movable plate 50 and is used to move with the movable plate 50 to block the opening of the dehydrogenation furnace body 10.

[0032] The material tray 60 is fixedly connected to the stopper plate 51;

[0033] The lifting plate 72 is mounted on the dehydrogenation furnace body 10 in a height-adjustable manner;

[0034] The baffle 70 is fixedly connected to the lifting plate 72. The upper wall of the cover 20 has a lifting hole 71 corresponding to the position of the baffle 70. The baffle 70 slides through the lifting hole 71 to divide the cover 20 into two parts.

[0035] This embodiment is implemented as follows:

[0036] In use, the cover door 20 is opened, the material is placed in the material tray 60, and then the moving plate 50 moves the stopper plate 51 and the material tray 60, so that the stopper plate 51 is inserted into the opening of the dehydrogenation furnace body 10, and then the dehydrogenation is completed. After the dehydrogenation is completed, the moving plate 50 returns to its original position. At this time, the lifting plate 72 moves the baffle 70 downward in the lifting hole 71, so that the baffle 70 divides the cover 20 into two parts. This separates the opening end of the dehydrogenation furnace body 10 from the material tray 60, and the heat energy of the dehydrogenation furnace body 10 will not enter the cover 20 in large quantities. Then the cover door 20 is opened, and the material is taken out from the material tray 60.

[0041] The lifting cylinder 73 can drive the lifting plate 72 to move vertically.

[0042] Please see Figure 1 , 2 3. The connecting component 40 includes a positioning ring 41 fixedly sleeved on the outer wall of the dehydrogenation furnace body 10, and a plurality of connecting blocks 42 are provided on the outer wall of the opening end of the cover 20. The connecting blocks 42 and the positioning ring 41 are connected by bolts 43.

[0043] The connecting block 42 on the cover 20 is connected to the positioning ring 41 on the dehydrogenation furnace body 10 by bolts, which facilitates fixing and disassembly.

[0044] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
