Description

A kind of rolling machine and method for rolling splitter
Technical field
The present invention relates to machine field, more particularly to a kind of rolling machine and method for rolling splitter.
Background technology
Fusion reactor is with deuterium tritium as nuclear fuel, therefore hydrogen isotope separation is the core of fusion reactor nuclear fuel cycle One of heart technology, by isotopic separation, a large amount of unburned deuterium tritium gas obtain profit again in can not only making reactor operation With, the effective control to the Environment release amount of tritium in fusion reactor running can be also realized, also can operate with the propagation of tritium Extract, plasma discharge and treatment etc..
It is big being separated using low temperature chromatography hydrogen isotope separation method (GC) or palladium Hot swapping chromatogram hydrogen isotope separation method , it is necessary to be filled with molecular screen material or palladium material composition splitter, splitter cooling in hollow straight tube during amount hydrogen isotope Cooling, make molecular screen material or palladium material saturation adsorbed hydrogen, usually splitter is integrally immersed in liquid nitrogen, due to The amount of liquid nitrogen held in the container of limited capacity is limited, and existing straight tube column splitter is immersed in liquid nitrogen finite volume, causes The molecular screen material of cooling or the amount of palladium material are limited, in order to increase the volume of the splitter being immersed in every time in liquid nitrogen, i.e., Increase single and cool down the amount of more molecular screen materials or palladium material, it is necessary to by the hollow straight of existing straight tube column splitter Pipe bends, to increase the volume that single is immersed in liquid nitrogen, wherein, hollow straight tube is rolled as helix tube is preferred.
Existing furling plate round machine can only roll a circle hollow straight tube, it is impossible to which it is helix tube to be rolled, and existing spring coiling machine Although helical form object can be rolled, the i.e. spring of product that its function and structure is just rolled in design in view of it Characteristic, the product that it is rolled has elasticity and resilience is serious, it is impossible to the two disk annulus close-packed arrays for making helix body phase adjacent.
The content of the invention
