Then, conductive plate and graphite are fastened with the bolt of 8~10mm.This connection type the main problems are as follows: is because of graphite
Hard brittleness causes after connecting in this way there are certain gap between bolt and graphite, and conductive plate is inadequate in conjunction with graphite
Securely, or even the bolt looseness that has falls off, and graphite carbon block is fallen into electrolytic cell when electrolysis, needs manually to pull out, increases charcoal consumption；
In addition contact drop is larger between conductive plate and graphite, increases power consumption.
Utility model content
The purpose of the utility model is to overcome the deficiency of the prior art, provide a kind of simple and practical in structure, conductive plate with
Graphite contact is good, molten-salt electrolysis rare earth metal anode easy to use.
A kind of molten-salt electrolysis rare earth metal anode of the utility model, the anode include graphite block and conductive plate, described
Graphite block top is provided with groove, and one end of conductive plate is inserted into the groove, and being filled with conducting medium in a groove will be conductive
Plate is affixed with graphite block；
The area of the groove is greater than the cross-sectional area of conductive plate；
The depth of the groove is between 30-150mm；To guarantee to have to enter groove for conductive plate and complete affixed depth；
The depth of the conductive plate insertion groove is at least 30mm, to guarantee that conductive plate has in enough areas and groove
Conducting medium is in contact, and guarantees affixed intensity；And the depth of conductive plate insertion groove is less than or equal to the depth of groove itself；
Spacing >=5mm of the conductive plate surface and groove inner surface is (to guarantee that conductive plate surrounding can be filled for affixed
Conducting medium, guarantee affixed stability)；
The groove opened up at the top of the graphite block meet conductive plate it is affixed needed for size in the case where, it is any for can opening up
Shape；Demand is provided for different electrolytic environments；It is preferred that the cross-sectional shape of groove is adapted with conductive plate insertion end shape.
The conducting medium be selected from conductive metal, the conductive metal be selected from metallic iron, ferroalloy, copper, copper alloy, aluminium,
One of aluminium alloy.
In the groove that conductive metal melt filling is opened up to graphite block top, conductive plate and graphite are carried out by soldering
Consolidation.
The utility model uses above-mentioned consolidation structure, changes the connection type of existing anode, has prevented graphite block because even
Obscission caused by defective tightness is connect, the connection between graphite block and conductive plate is enhanced；Reduce tie point voltage drop, drop
The cost of electrolysis is greatly saved in the power consumption of low re metal electrolyzing, is adapted to the demand in market.
