Sustainable discharging device for preparing rare earth electrolysis waste fused salt and implementation method thereof

Abstract

The invention discloses a sustainable discharging device for preparing rare earth electrolysis waste fused salt. The sustainable discharging device comprises a bottom plate, a quantitative control mechanism, a discharging port, a transmission motor and a hopper, a reciprocating transmission part rotates to enable a quantitative spacing plate to do reciprocating motion in a discharging channel, when an upper baffle moves into a second storage groove, the discharging channel is sealed by a lower baffle, when molten salt in the hopper falls to the position above the lower baffle and the transmission rod drives the lower baffle to move into a first storage groove, the upper baffle seals an upper end of the discharging channel, and the molten salt at an upper end of the lower baffle falls and is discharged, so that quantitative feeding is realized, and timely adjustment is facilitated. The invention further discloses an implementation method of the sustainable discharging device for preparing the rare earth electrolysis waste molten salt, when a transmission plate moves up and down, convex teeth and gears are engaged to drive a shaft body to rotate in a reciprocating mode, a plurality of dredging rods rotate in a matched mode, the molten salt can be well loosened, the dredging rods are relatively dense, and massive fused salt can be blocked or ground and crushed with the inner wall of a loose pipe.

Description

technical field [0001] The invention relates to the technical field of rare earth preparation accessories, in particular to a sustainable feeding device for rare earth electrolysis waste molten salt preparation and an implementation method thereof. Background technique [0002] Rare earth is a general term for seventeen metal elements including lanthanides, scandium and yttrium in the periodic table of elements. There are 250 kinds of rare earth minerals in nature. Rare earth metal production, the process of reducing rare earth compounds into metals. The rare earth metal products produced by the reduction contain 95% to 99% of rare earth, and are mainly used as additives for iron and steel, nonferrous metals and their alloys, and as raw materials for the production of rare earth permanent magnet materials, hydrogen storage materials and other functional materials. Since the Swedish Musander first obtained metal cerium in 1826, he has been able to produce all rare earth met...

Problems solved by technology

[0003] In the process of electrolysis of industrial-grade rare earth molten salt, the amount of molten salt needs to be continuously supplemented. The structure of the ordinary feeding mechanism is too simple, and usually only a certain amount of one-time addition can be prepared in advance, and quantitative and gradual addition cannot be realized. , because it is generally necessary to control the amount of metal in each furnace to account for 60% of the electrolytic cell, the addition of molten salt needs to be progressive, and the existing feeding mechanism needs to prepare a suitable amount in advance, the process is complicated, and the preparation accuracy is reduced. Secondly, some There is agglomeration phenomenon in the molten salt, which reduces the contact area with the solution and affects the efficiency of the experiment
