Embodiment
A kind of metal electrolysis means comprises the electrolysis cells of being made up of anode 2 and negative electrode 3 in electrolyzer 1 and the electrolyzer.The cell body of electrolyzer 1 is square, by carbon steel or stainless steel through being welded.Anode 2 and negative electrode 3 insert from the bottom of electrolyzer 1, are provided with barrier film 12 (with reference to Fig. 2) between anode 2 and negative electrode 3; The top of negative electrode 3 is provided with metal collecting hood 4, and its delivery line 8 by the top is fixed on electro bath-lid (11) and upward and with metal hold tank 6 links to each other; The top of anode 2 is provided with gas collection cap 5, and it is fixed on electro bath-lid (11) by vapor pipe 11 and goes up (with reference to Fig. 1); Metal collecting hood 4 is an arc, and the gradient at its top is 5-15 ℃; Gas collection cap 5 is a bucket shape; And metal collecting hood 4 fuses (with reference to Fig. 2) by negative and positive interpolar barrier film 12 with gas collection cap 5, and this electrolyzer can guarantee that metallic lithium has certain altitude in melting salt.Metallic lithium in cover with after ionogen separates, by the buoyancy of fused salt to liquid lithium, liquid lithium along sloping and on, and flow in the airtight metal hold tank 6 via delivery line 8.Barrier film 12, metal collecting hood 4, gas trap 5 are by A
9Alloy is made.Metal hold tank 6 is connected with anaerobic work box 7 by the control valve 9 of bottom, and anaerobic work box 7 is provided with metal mold 13, and metallic lithium is controlled the mold 13 interior directly ingot castings that on time are directed in the anaerobic work box 7 in the basin 6 by the metal valve 9 of basin bottom.Metal tank 6 horizontal sections are trilateral, are made by stainless steel, and its outer wall is provided with heating unit.The casing of anaerobic work box 7 is made by stainless steel, there are two handle holes 18 in the casing front, and a pair of rubber gloves is installed above, and the front is provided with synthetic glass form 17 and is used for operation in the inspection box, the casing left side is provided with feed inlet and outlet 14, and casing is provided with the pipeline 15 and the venting port 16 of applying argon gas.Be provided with in the work box by oil groove and mold 13 cast metals devices dimerous.
Exsiccant lithium chloride and Repone K are added in the electrolyzer starting the arc, fused salt by a certain percentage.After electrolyzer 1 is set up thermal equilibrium, logical direct current electrolysis, metallic lithium enters in the collecting hood 4 after negative electrode 3 is separated out, growth along with electrolysis time, collection is many more more in collecting hood 4 for metallic lithium, the buoyancy that liquid lithium is borrowed melting salt along the slope and on, continuously flow in the metal hold tank 6.The outer wall of metal hold tank 6 has heating unit, and its temperature employing control automatically makes the lithium in the jar remain liquid state, and metallic lithium is controlled direct ingot casting in the mold 13 that on time is directed in the anaerobic work box 7 by the metal valve 9 of hold tank bottom.Anaerobic work box 7 is taken air in the case away with vacuum pump before work, fills the argon gas through purifying again in case, successively repeatedly for several times, in work box atmospheric oxygen less than 750ppm, nitrogen less than 750ppm till, work box can carry out work.Mold is placed in the oil groove, during ingot casting, by the metallic lithium that hold tank is discharged, borrows the power that falls that oil is arranged, and oil produces buoyancy to metallic lithium, and metallic lithium floats on the oil.Oil quickens the ingot casting cooling, prevents the metallic lithium oxidation.The metallic lithium that ingot casting is good packages the back and takes out in the anaerobic workstation.Through continuous operation, obtain the grade of resultant metal lithium: 99.5%.
