Embodiment Construction

[0009] The rotary hydrogen crushing furnace includes a rotatable furnace 4 supported on supports 13 at both ends, an electric heating furnace 3 located on the outer layer of the furnace, a rotary drive mechanism for the furnace, and a furnace for vacuuming and charging hydrogen. One end of the furnace 3 is the inlet and outlet, and the other end is sealed and communicated with the vacuum device and the gas distribution device. The electric heating furnace consists of a left and right furnace body 1 that can be opened and closed. 2, the left and right furnace bodies are respectively placed on the support frame 14 with rollers 9 at the bottom. A spiral piece 8 is provided in the furnace 3 . There is a support bearing 12 at the end of the support member 13, and the two ends of the rotatable furnace are supported on the support bearing 12, so that the furnace can rotate; one end of the rotatable furnace is connected with the vacuum device and the gas distribution through the dynam...

Abstract

The present invention relates to RE alloy crusher and is one rotary hydrogen crushing furnace. It includes rotary furnace, electric heater outside the furnace, furnace rotating drive mechanism and furnace vacuum pumping and hydrogen filling unit. The furnace has feeding and discharging port at one end and is connected to vacuum pumping and hydrogen filling unit at the other end. The electric heater consists of right and left bodies on the support with rollers. Inside the furnace, there are spiral sheets. Compared with available hydrogen crushing furnace with internal heater structure, the present invention with outer heater structure has fast temperature decreasing speed of the furnace and material inside it, simplified operation, high efficiency, improved safety and operation performance.

Description

technical field [0001] The invention relates to a crushing device for rare earth alloys (such as rare earth permanent magnet materials, hydrogen storage materials, etc.), in particular to a rotary hydrogen crushing furnace. Background technique [0002] Utilizing the hydrogen absorption characteristics of rare earth alloys to solve the problem of its crushing has appeared for nearly ten years. At present, there are hydrogen crushing furnaces with various structures at home and abroad. Volume expansion, especially the difference in grain boundary and crystal expansion, causes many cracks in the rare earth alloy, so as to achieve the purpose of breaking. Existing hydrogen crushing devices are divided into two types in terms of structure: rotary type and static type, and in terms of heating methods, they are divided into internal heating type and external heating type. The so-called rotary hydrogen crushing furnace is that the furnace is in a rotating state during work, and th...
