Vertical ladle for vacuum suction and injection of liquid rare earth metal

Abstract

The invention provides a vertical ladle for vacuum suction and injection of liquid rare earth metal. The vertical ladle comprises a molten metal containing ladle body, a liquid outlet sealing cap, a sealing cap gas circuit opening and closing assembly, a liquid suction pipe, a ladle body connecting piece and a tilting component. According to the vertical ladle, the gas pressure in the ladle is adjustable, the situation that electrolyte cannot enter a liquid storage inner container in the pipe inserting process of the liquid suction pipe is prevented, metal, the electrolyte and the like can bethoroughly poured out of the liquid storage inner container in an upside down pouring mode, the defect that the electrolyte and slag are left in the ladle is overcome, the temperature drop of molten metal in unit time can be greatly reduced through a heat preservation layer structure, the requirement that liquid metal is extracted to the same ladle from different electrolytic tanks one by one andcollected together for pouring (ingot casting) is met, and after the liquid rare earth metal in the tanks is extracted and poured, the components are mixed evenly.

Description

technical field [0001] The invention belongs to the field of metal smelting, in particular to a vertical table bag for vacuum suction and injection of liquid rare earth metals. Background technique [0002] At present, the equipment that uses vacuum suction to take the molten metal out of the electrolytic cell, such as the aluminum outlet bag, is suitable for the production of metal aluminum, magnesium, etc. by electrolysis, but it is not suitable for the production of rare earths by electrolysis because of the large size, complexity and defects of electrolyte slagging. Metal, the way to discharge rare earth metals from the electrolytic cell is generally to use manual or mechanical scoops and spoons to take out the equipment and methods. When taking out the operation, the electrolytic cell needs to be powered off, which has the disadvantage of reducing production. Furthermore, the liquid rare earth metals taken out each time The amount is small, and there are shortcomings of...

[0002] At present, the equipment that uses vacuum suction to take the molten metal out of the electrolytic cell, such as the aluminum outlet bag, is suitable for the production of metal aluminum, magnesium, etc. by electrolysis, but it is not suitable for the production of rare earths by electrolysis because of the large size, complexity and defects of electrolyte slagging. Metal, the way to discharge rare earth metals from the electrolytic cell is generally to use manual or mechanical scoops and spoons to take out the equipment and methods. When taking out the operation, the electrolytic cell needs to be powered off, which has the disadvantage of reducing production. Furthermore, the liquid rare earth metals taken out each time The amount is small, and there are shortcomings of composition differences between pools and between times. The aluminum (magnesium) type table bag has the disadvantage of slagging, good heat preservation effect, and is suitable for the production of liquid rare earth metal electrolytic cells. The equipment for vacuum pumping liquid rare earth metals can not only increase the output of electrolytic cells, but also reduce labor intensity. Improve the quality of rare earth metals
