Reinforced type rare earth electrolysis graphite crucible

Abstract

The invention discloses a reinforced type rare earth electrolysis graphite crucible. The reinforced type rare earth electrolysis graphite crucible structurally comprises a box body, convection nets, plate bases, an overturning shaft and an observing plate; and the side edge positions of the box body are provided with the convection nets. The reinforced type rare earth electrolysis graphite crucible has the beneficial effects that in a manner of friction heat conduction of heat conduction wheels in the structure, heat can be transmitted in a tangent line and tangent plane manner; meanwhile, theheat is continuously emitted downwards in a 360 degree manner through a heat dissipating ring; the side edge and bottom edge position of a graphite furnace body is used for bearing the heat transmitted by the heat conduction wheels by adopting heat receiving plates of spaced heating disks, and the divergency range of the heat is gradually widened in a point-to-point manner; and the heat of an annular disk is diffused in an octangle grid shape in an annular outward distribution manner, a gap exists between the annular disk and the graphite furnace body, and it is effectively prevented that thegraphite furnace body cracks and the preparation effect is affected.

Description

technical field [0001] The invention relates to the field of graphene processing, in particular to an enhanced rare earth electrolytic graphite crucible. Background technique [0002] In the process of producing rare earth metals by molten salt electrolysis, once the lining of the rare earth electrolytic cell is severely damaged, the service life of the electrolytic cell cannot reach the standard. In the early damage accident of the rare earth electrolytic cell, the graphite lining cracks and breaks There are many cases like perforation. On the one hand, air and electrolyte will gradually penetrate into the interior of the graphite lining during molten salt electrolysis to produce rare earth metals, which will oxidize and corrode the lining of the electrolytic cell and cause damage to the graphite lining. On the other hand, What has an important impact on it is the longitudinal crack extending from the top edge of the crucible caused by excessively fast heating of the graphi...

[0002] In the process of producing rare earth metals by molten salt electrolysis, once the lining of the rare earth electrolytic cell is severely damaged, the service life of the electrolytic cell cannot reach the standard. In the early damage accident of the rare earth electrolytic cell, the graphite lining cracks and breaks There are many cases like perforation. On the one hand, air and electrolyte will gradually penetrate into the interior of the graphite lining during molten salt electrolysis to produce rare earth metals, which will oxidize and corrode the lining of the electrolytic cell and cause damage to the graphite lining. On the other hand, What has an important impact on it is the longitudinal crack extending from the top edge of the crucible caused by excessively fast heating of the graphite crucible, especially when the bottom and lower edge of the crucible are heated much faster than the top. Therefore, As the weakest link in the electrolytic cell, how to avoid cracks in the graphite lining is an important prerequisite for the production of rare earths. Based on the above premise, this case developed an enhanced rare earth electrolytic graphite crucible to solve this problem
