Abstract

The utility model discloses a new electrolytic tank used for molten salt electrolysis, particularly the electrolytic tank used for producing rare earth metal. The anode (1) of the electrolytic tank is a barrel-shaped object without a bottom, the barrel-shaped object is made of carbon material, and the tank shell (2) of the electrolytic tank is a container made of the carbon material. The electrolytic tank is used for producing the rare earth metal, the tank is easy to change, labor is saved, energy is saved, and impurities are not generated for rare earth metal products.

Description

Electrolytic bath

The utility model relates to a kind of fused salt electrolysis electrolyzer, particularly produces the electrolyzer that rare earth metal is used.

Produce the electrolyzer that rare earth metal is used with fused salt electrolysis process now, its anode is the container made from carbon material, and pot shell is the container that metallic substance is made, during use with anode jacket in pot shell.This traditional electrolyzer has following disadvantage: 1. when changing groove (change anode or change anode and pot shell simultaneously), need stop the groove cooling earlier, then the anode anode scrap be extracted, the residue ionogen in the anode anode scrap be poured in the new anode again.And when new groove is worked, also need reset.So not only expend man-hour, reduce output, and stop the groove cooling and reset process all will waste a large amount of energy.2. when the male receptacle wall pore when big or crack and seepage, ionogen can ooze out with the metal pot shell from the male receptacle wall and be communicated with, makes metal pot shell participation electrolytic process, and its metal ingredient then may become impurity and enter in the rare earth metal product, has reduced the grade of product.3. in an anodic use, the pole span that causes along with anodic consumption changes greatly.

Task of the present utility model provides that a kind of to change groove easy, does not produce the electrolyzer of impurity, to overcome the disadvantage of traditional electrolyzer.

Task of the present utility model is achieved in that the container made from carbon material as pot shell, and anode then is no bottom tube-like thing---the anode tube made from carbon material.During use, with the anode tube in liner is enclosed within pot shell.Because the plain pot shell life-span of the charcoal of novel electrolytic bath is than long several times of common metal pot shell, so often need only change the anode tube when changing groove.When the anode tube is consumed need change the time, stopping groove earlier raises negative electrode, then the anode anode scrap is extracted from pot shell, and giving in advance in the good new anode tube insertion pot shell of heat, it is more faster than the groove process of changing of traditional electrolyzer that this changes the groove process, thereby bring series of advantages: 1. stop groove time weak point, improved plant factor, and improved output.2. when changing the anode tube, the cooling of must not lowering the temperature, new groove must not reset yet, and heat-energy losses is little, save energy.3. because of the pot shell container directly contacts a part that becomes electrolytic anode with ionogen, but pot shell also makes with carbon material, so can not produce impurity to the rare earth metal product.4. can do the anode barrel thinner, make it in the use of an anode tube, the pole span variation that causes because of anode consumption reduces.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the sectional view according to a kind of embodiment of the novel electrolytic bath that the utility model proposes.

This electrolyzer comprises carbon anode tube (1), and its lining is in the plain pot shell of charcoal (2).

Fig. 2 provides the sectional view of another kind of embodiment.The characteristics of present embodiment are that a groove (3) was arranged on the interior end of pot shell (2), and the end surface shape of flute profile and anode tube (1) adapts.During use, anode tube (1) is inserted among the groove (3) of pot shell (2).

Fig. 3 provides the sectional view of another embodiment.The characteristics of this embodiment are: a step (4) is arranged at the interior end of pot shell (2), and the end surface shape of the shape of table top and anode tube (1) adapts.During use, anode tube (1) stands on the step (4) of pot shell (2).

More than anode tube (1) and pot shell (2) among each embodiment, all available two kinds of approach manufacturings: 1. be shaped with the turning of Graphite Electrodes rod; With carbon material (broken and pitch) as graphite according to the manufacture method of carbon product make, as getting final product by following technical process:

Fragmentation → screening → batching → mix and pinch → be shaped → roasting → (mechanical workout).
