Abstract
The utility model discloses a kind of hydrogen crushing furnace, include a plurality of reacting furnaces, a plurality of reacting furnaces are connected successively by pipeline, on pipeline, between adjacent two reacting furnaces, be separately installed with control valve, the air inlet of a plurality of reacting furnaces is connected with respectively the air inlet pipe of leading to sources of hydrogen, is connected with respectively vacuum extractor on reacting furnace.The utility model is simple in structure, and when work, the reacting furnace in the dehydrogenation reaction stage provides hydrogen by pipeline to the reacting furnace in the hydrogen abstraction reaction stage, and hydrogen is recycled, and has effectively saved resource, has avoided waste.
Description
Technical field
The utility model relates to a kind of hydrogen crushing furnace of realizing rare earth alloy efflorescence.
Background technology
Hydrogen crushing furnace be a kind of hydrogen that utilizes as medium, utilize the combination reaction between rare earth metal and hydrogen and make rare earth alloy reach broken a kind of equipment, be widely used in the powder metallurgy industry such as neodymium iron boron.
The reaction of hydrogen and rare earth alloy is as follows:
1) hydrogen abstraction reaction: xH2(gas)+RTy(is solid)=RH2yTy(is solid),
2) dehydrogenation reaction: RH2yTy(is solid)=xH2(gas)+RTy(is solid).
In above-mentioned reaction, R represents thulium, and T represents other chemical elements in rare earth alloy.By hydrogen abstraction reaction, rare earth alloy and hydrogen react, and the factors such as thermal expansion between the own material of its hydride and rare earth alloy make rare earth alloy start efflorescence.Rare earth alloy reaches after desirable efflorescence effect, by the mode of heating, the backward reaction release place hydrogen of the hydride generation hydrogen abstraction reaction of rare earth alloy.In whole process, hydrogen participates in the process of rare earth alloy efflorescence as the medium of efflorescence rare earth alloy, is finally released, seldom residual in rare earth alloy, has avoided again other crumbling methods rare earth alloy to be introduced to the shortcoming of impurity.
The mode of operation of existing hydrogen crushing furnace is as follows:
1) shove charge: rare earth alloy powder is packed in an airtight container;
2) vacuumize: use vacuum machine the Bas Discharged in closed container;
3) hydrogen is broken: in closed container, be filled with hydrogen, hydrogen and rare earth alloy generation hydrogenation, product efflorescence;
4) dehydrogenation: by closed container is heated, make hydrogen separated with rare earth alloy;
5) cooling coming out of the stove: after hydrogen discharges and to finish, closed container is carried out cooling, vacuumize, fill after inert gas, take out rare earth alloy.
In certain embodiments, hydrogen directly enters atmosphere afterwards by the dilution of carrying out low concentration with nitrogen, causes a large amount of wastes.
Utility model content
The purpose of this utility model is to provide a kind of hydrogen crushing furnace, and during work, the reacting furnace in the dehydrogenation reaction stage provides hydrogen by pipeline to the reacting furnace in the hydrogen abstraction reaction stage, and hydrogen is recycled, and to economize on resources, avoids waste.
The technical solution of the utility model is as follows:
A kind of hydrogen crushing furnace, include a plurality of reacting furnaces, it is characterized in that: described a plurality of reacting furnaces are connected successively by pipeline, on described pipeline, between adjacent two reacting furnaces, be separately installed with control valve, the air inlet of described a plurality of reacting furnaces is connected with respectively the air inlet pipe of leading to sources of hydrogen, is connected with respectively vacuum extractor on a plurality of reacting furnaces.
Described hydrogen crushing furnace, is characterized in that: in described a plurality of reacting furnaces, be separately installed with temperature control equipment.
The beneficial effects of the utility model:
The utility model is simple in structure, and when work, the reacting furnace in the dehydrogenation reaction stage provides hydrogen by pipeline to the reacting furnace in the hydrogen abstraction reaction stage, and hydrogen is recycled, and has effectively saved resource, has avoided waste.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, a kind of hydrogen crushing furnace, include a plurality of reacting furnaces 1, a plurality of reacting furnaces 1 are connected successively by pipeline 2, on pipeline 2, between adjacent two reacting furnaces, be separately installed with control valve 3, the air inlet of a plurality of reacting furnaces 1 is connected with respectively the air inlet pipe 5 of leading to sources of hydrogen 4, is connected with respectively vacuum extractor 6 on reacting furnace 1.
In the utility model, in a plurality of reacting furnaces 1, be separately installed with temperature control equipment, the chemical reaction in a plurality of reacting furnaces 1 is carried out to temperature control.
