The graphite anode is characterized by comprising a plurality of anode plates, wherein the anode plates are connected in parallel; at least two inner wire holes are formed in the top surface of each anode plate; adjacent anode plates are connected through anode clamps; each anode clamp is arranged above a graphite electrolytic cell, spans two adjacent anode plates and is a section of circular-ring-shaped metal plate of which the inner diameter and the outer diameter are equal to those of the corresponding graphite anode plate; each metal plate is connected with the positive electrode of a power source; at least two inner wire holes are formed in each metal sheet and are aligned with the inner wire holes in two corresponding adjacent graphite anode plates; and the inner wire holes in the metal plates are connected with the corresponding inner wire holes in the anode plates through bolts. The graphite anode provided by the utility model is easy to replace and has the advantages that the fluctuation caused to the liquid level of molten salt in an electrolytic furnace is small, the fluctuation of the furnace temperature is small, temperature changes are small, the phenomena of furnace shutdown is avoided, and the service life of the electrolytic furnace is prolonged.
Description
Technical field
The utility model relates to a kind of graphite anode, and particularly rare earth oxide-fluoride molten salt electrolytic process is produced employed graphite anode in rare earth metal and the alloy process, and refers in particular to employed graphite anode in circular electrolyzer.
Background technology
Because employed graphite anode is a kind of consumable anode in rare earth oxide-fluoride molten salt electrolysis system, need in process of production regularly to change.
Production practice are found, adopt the hollow cylinder graphite anode to have following defective: inconvenient operation, because graphite anode is an integral body, heavy, difficulty is carried during replacing; Before and after the anode change, the fused salt liquid fluctuating is big in the electrolytic furnace; Before and after the anode change, furnace temperature fluctuation is big.
Because the new graphite anode tube of changing is a cold conditions; Occur new anode easily and put down the dead stove phenomenon that the back causes owing to the furnace temperature rapid drawdown, this has not only had a strong impact on electrolysis production, also makes fused salt be condensed in inboard wall of burner hearth easily simultaneously; Burner hearth is diminished, thereby influence the work-ing life of electrolytic furnace.
Secondly the anode tube that more renews will cut off the power supply, and furnace temperature is fallen too fastly, and to be replaced finishing need be heated up again, has only furnace temperature to rise to normal temps and just begins electrolysis, promptly influences output and influences quality product again.
Summary of the invention
The purpose of the utility model provides a kind of graphite anode; Its fluctuation of changing easily, when changing fused salt liquid level in the electrolytic furnace being caused is little, replacing front and back furnace temperature fluctuation is little, be difficult for producing violent difference variation; Overcome because the dead stove phenomenon that the furnace temperature rapid drawdown causes; Improve electrolytic furnace work-ing life, and do not needed the preheating that heats up again in the whole replacing process, thereby do not influenced quality product and output.
For this reason, the utility model provides a kind of graphite anode, and this anode integral body is hollow cylinder, and it is characterized in that: graphite anode is made up of a plurality of anode strips, parallel connection between each anode strip, and the end face of each anode strip is provided with at least two internal thread holes; Connect through the anode folder between the adjacent anode strip, each anode folder is arranged at above graphitic cell, crosses over two adjacent anode strips; Each anode folder is the tinsel of the one section annular all identical with outside dimension with graphite anode sheet internal diameter; This tinsel links to each other with positive source; Also be provided with at least two internal thread holes on this tinsel; Internal thread hole on this tinsel is aimed at the internal thread hole on corresponding two adjacent graphite anode sheets one by one, and corresponding internal thread hole is connected through bolt on the internal thread hole on this tinsel and the anode strip.
Preferably, the quantity in said internal thread hole is 2-6.
Preferably, the quantity in said internal thread hole is 2-5.
Preferably, the quantity in said internal thread hole is 2.
Preferably, said metal clip is the A3 iron plate.
Preferably, the quantity of said anode strip is 4～12.
Preferably, the size of each said anode strip is all identical.
Preferably, the size of each said anode folder is all identical.
Preferably, the internal thread hole uniform distribution of each said anode strip.
Preferably, the internal thread hole uniform distribution of each said anode folder.
According to the utility model, every graphite anode is lighter, carries easily during replacing; Because graphite anode has been divided into small pieces, the fluctuation that during every replacing fused salt liquid level in the electrolytic furnace is caused is little; Furnace temperature fluctuation was little before and after graphite anode was changed.Change the small pieces anode, be difficult for producing violent difference variation.Overcome because the dead stove phenomenon that the furnace temperature rapid drawdown causes, improved electrolytic furnace work-ing life.
