Abstract

The invention relates to a hydrogen crushing furnace, which includes a furnace, an electric heating furnace and a cooling device. The furnace includes a furnace body and two first rotating shafts respectively arranged at both ends of the furnace body. The cooling device includes The cooling tank directly below, the first lifting device for driving the cooling tank up and down, the exhaust hood directly above the furnace and the second lifting device for driving the exhaust hood up and down, on the cooling tank A first water inlet pipe and a drain pipe are provided, and an exhaust pipe is provided on the exhaust hood, and the exhaust pipe communicates with the negative pressure device. The hydrogen crushing furnace provided by the invention has higher cooling efficiency, and at the same time, a large amount of water vapor generated during the cooling process can be effectively controlled or discharged, thereby improving the working environment of workers. At the same time, the invention also provides a cooling method for the hydrogen crushing furnace.

Description

technical field [0001] The invention relates to the technical field of permanent magnet preparation, in particular to a hydrogen crushing furnace, and also relates to a cooling method for the hydrogen crushing furnace. Background technique [0002] Hydrogen crushing furnace is a kind of ingot or flake rare earth alloy material formed into powder by non-mechanical force. Mainly through the reaction of hydrogen with rare earth alloys (such as NdFeB alloy Nd2Fe14B), the intergranular fracture and transgranular fracture generated by the rare earth alloy (such as NdFeB alloy) in the process of hydrogen absorption and hydrogen release lead to rare earth alloy powder It is a process equipment that forms an embrittlement and crushing process to obtain rare earth alloy powder with a certain particle size. [0003] The current hydrogen crushing furnace mainly includes a rotatable furnace, an electric heating furnace located outside the furnace, and a liftable cooling device located d...
