Description

Technical Field

[0001] The utility model relates to the technical field of molybdenum crucibles, in particular to a split molybdenum crucible for distilling metal samarium. Background Art

[0002] Distillation of samarium metal is a method of purifying samarium metal, usually carried out under high temperature and vacuum conditions. Distillation of samarium metal requires the use of specialized distillation equipment, which usually includes a distillation furnace, condenser, vacuum pump, and molybdenum crucible. Currently, molybdenum crucibles are usually designed as one-piece, and a small number of split-piece designs are also available. However, after continuous use for more than half a year, molybdenum crucibles will deform and crack, which can easily affect the service life of the molybdenum crucible.

[0003] In order to improve the service life of the molybdenum crucible, the utility model with patent announcement number CN206721304U discloses a split molybdenum crucible and distillation furnace, including a plurality of molybdenum sleeves nested up and down in a cage-like manner, a molybdenum guide cap installed above the uppermost molybdenum sleeve, and a graphite protective sleeve arranged on the outside of each molybdenum sleeve. The graphite protective sleeve protects the molybdenum crucible, effectively preventing it from deformation or cracking, and extending the service life of the molybdenum crucible. Although it is convenient to reduce the deformation and cracking of the molybdenum crucible, after the multiple molybdenum sleeves are nested together up and down, the gaps between adjacent molybdenum sleeves need to be tightly sealed by a filler layer. The filler layer will stably connect the adjacent molybdenum sleeves. When one of the molybdenum sleeves or the graphite protective sleeve is damaged, it is not convenient to disassemble and replace them separately, and they need to be replaced as a whole, which easily causes waste of resources.
