Description
Technical field
The utility model relates to a kind of component for rare earth molten-salt electrolysis equipment more particularly to a kind of overlapping type rare earth electricity
Solve anode strip.
Background technique
Rare earth molten-salt electrolysis technique is the main stream approach of rare earth metal (alloy) production preparation, by cathode bar and sun when electrolysis
Pole piece forms electrode and generates electric field, and cathode bar and anode strip are inserted into electrolytic cell fused salt when electrolysis, and smelting temperature is at 1000 DEG C
More than.Rare Earth Electrolysis anode strip is graphite material production, the carbon of fusion process graphite anode sheet panel under electric field and high temperature action
With the oxygen generated reactive gas in rare earths material, it can constantly volatilization consume, need to regularly replace.
For round rare earth electrolysis cell, the early stage anode of production is that graphite material is made into hollow cylinder, is integrally put
Enter electrolytic cell, referred to as tubbiness anode；Later, it is 4 equal portions by radial subdivision on the basis of tubbiness anode, forms fan cylinder, claim
It for sheet-like anodes, is easily changed after sheet-like anodes consumption, when replacement influences the working of a furnace small, and existing Rare Earth Electrolysis technique generally makes
With this sheet-like anodes.
This structure the problem is that:
Anode strip is mounted between graphite crucible furnace wall and cathode, and there are gaps between anode strip and anode strip.It was electrolysed
Cheng Zhong, the fused salt containing rare earth oxide are electric conductors, make graphite crucible furnace wall and anode equipotential, therefore cathode passes through anode strip
Between gap and furnace wall form electric field, under electric field action, the carbon of oxygen and furnace wall in rare earths material reacts volatilization, makes
It is lost at furnace wall, reduces the service life of graphite crucible, be easily changed and fail effective protection price with the lower anode strip of price
Expensive electrolytic cell graphite crucible.
Utility model content
The purpose of the utility model is to provide a kind of overlapping type Rare Earth Electrolysis anode strips.
The purpose of this utility model is achieved through the following technical solutions:
The overlapping type Rare Earth Electrolysis anode strip of the utility model, including the hollow cylinder being processed by graphite material,
The radial of hollow cylinder is split into 4 equal portions by 15-30 ° of angle, forms four bevel edge fan cylinder anodes, and four piece bevel edges fan column
Body anode is inserted into electrolytic cell, the integral hollow cylinder of the mutual overlapping combination of adjacent bevel edge.
Overlapping type provided by the embodiment of the utility model is dilute it can be seen from above-mentioned technical solution provided by the utility model
Native electrolytic anode piece, every bevel edge fan cylinder anode are inserted into electrolytic cell, and bevel edge is mutually overlapping, makes in electrolytic cell graphite crucible
Cathode and furnace wall do not generate direct electric field, avoids furnace wall consumption, effective protection graphite crucible.Solves existing sheet-like anodes band
The problem of carrying out groove body loss had not only been conveniently replaceable but also can protect groove body, extended groove body graphite crucible service life.

In figure:
1. subdivision line, 2. mounting holes, the outer diameter before 1. subdivision of Φ, the internal diameter before 2. subdivision of Φ, H. anode is high, α subdivision angle
(15-30 °), β anode bottom taper (10-20 °).
Specific embodiment
The utility model embodiment will be described in further detail below.Do not make in the utility model embodiment in detail
The content of description belongs to the prior art well known to professional and technical personnel in the field.
The overlapping type Rare Earth Electrolysis anode strip of the utility model, preferable specific embodiment is:
Including the hollow cylinder being processed by graphite material, radial in hollow cylinder is split by 15-30 ° of angle
4 equal portions form four bevel edge fan cylinder anodes, and four piece bevel edge fan cylinder anodes are inserted into electrolytic cells, and adjacent bevel edge is mutual
The integral hollow cylinder of overlapping combination.
The bottom of every anode cuts out taper by 10-20 °.
The taper of the supporting surface of the taper and graphite crucible waist of anode bottom coincide.
The overlapping type Rare Earth Electrolysis anode strip of the utility model, is processed into hollow cylinder for graphite material, in open circles
The radial of cylinder is split into 4 equal portions by 15-30 ° of angle, forms bevel edge and fans cylinder anode；10-20 ° is pressed again in the bottom of every anode
Cut out taper.As a result, in every bevel edge fan cylinder anode insertion electrolytic cell, bevel edge is mutually overlapping；The taper of anode bottom with
The taper of graphite crucible waist coincide.This two aspect makes electrolytic cell graphite crucible inner cathode and furnace wall not generate direct electric field, keeps away
Exempt from furnace wall consumption, effective protection graphite crucible.It solves the problems, such as that existing sheet-like anodes bring groove body to be lost, was both conveniently replaceable
Groove body can be protected again, extend groove body graphite crucible service life.
Specific embodiment:
As shown in Figure 1, Figure 2, Figure 3 shows, 4 anodes of subdivision are inserted into burner hearth, the side of each anode is overlapping together, is formed
Tubbiness, without radial gap between anode strip；Anode strip bottom and electrolytic cell waist coincide, also without radial gap.In yin when electrolysis
Pole, anode electric field act on lower heating melting rare earths material, cathode adsorbing metal ions, the oxygen hair in the carbon and raw material of graphite anode
Raw reaction volatilization has blocked cathode and furnace since the side of anode strip is overlapping together, the bottom of anode strip and crucible taper coincide
Wall forms electric field channel, and the carbon of furnace wall will not directly react with the oxygen of raw material, protect furnace wall, reduce graphitic cell
Consumption.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
Subject to the scope of protection of the claims.
