SU377413A1 - ROTOR ELECTROLIZER FOR METAL REFINING IN MELTED MEDIA - Google Patents

Description

one

The invention relates to the field of electrolytic refining of metals in molten media.

A rotary electrolyzer for refining metals in molten media is known, which consists of an anode basket lined with refractory bricks and a mechanism for cutting, collecting and transporting cathode sludge.

The difference of the proposed electrolyzer is that the anode basket is equipped with an. cloned ridges. This allows you to create a night-time movement of the anode material along the cell.

FIG. 1 shows the described electrolyzer, cross section; in fig. 2 is the same; the section along A-L in FIG. one; in fig. 3 is a diagram of the movement of the anode material along the axis of the electrolyzer.

The rotor electrolyzer consists of a hermetic drum / serving as an anode corset and a bath of a reciprocating (swinging) electrolyzer lined inside with a fire-brick and equipped with a graphite bottom for a current lead; the cathode 2, which has the shape of a body of revolution and is placed on the shaft 5; shaft 4 with incisors 5 fixed on it; screw 6; gear wheel 7 and the worm gear 5. The drum is equipped with an airtight bunker I, Nozzle W, a plug-in tube //, a throat

12 and a hopper 13 for cathode sediment. Inside the drum, small ridges 14 and large ridges 15 are embedded, which, with the return movement of the anode basket, ensure the flow direction of the anode material along the axis of the electrolyzer. . Electrolier works as follows. .

 The electrolysis cell bath, which is at the same time its anode basket, with the auger 6 rotating from the screw pair, is fed from the bunker 9 anode material. The latter, by means of the ridges 14 and 15, making a swinging motion together with the anode basket, moves along its axis from the loading point to the ground in the opposite end. Next, the cell is crimped and heated. The molten electrolyte is then poured from the melter to the desired level. Some time the leveling of the total electrolyte temperature occurs, after which constant current is activated to conduct the electrolysis process, which is accompanied by periodic rocking of the anode basket by 90-100 ° in order to mix the anode material, remove the crushed crust and improve convection during the electrolysis process. In order to create a flow of movement of the anode material in the process of its study from the place of loading into the opposite side of the electrolyzer, the channel T1 is carried out. The movement of the anode basket 150 °.

The electrolysis process is caused by the dissolution of the refined metal, which goes to the cathode 2, and when the sediment at the cathode is periodically cut by the incisors 5, mounted on the rotating shaft 4, the metal is poured through the neck 12 into the hopper 13. The process of cutting and removing the cathode sediment with electrolyte impurities as well as the removal of worked sludge - sludge through the plug pipe // is accompanied

; 0 days ago; now. M compensation of materials removed from the electrolyzer from the bunker 9.

And p. E; m 6 tons of the invention

A rotary electrolyzer for refining metals in molten media, consisting of an anodic basket lined with refractory bricks, and a cut-off mechanism for collecting and transshipment of an electrical sludge, characterized in that, in order to create a two-stream anodic material and anode material along the electrolyzer, the anodic basket provided with inclined ridges.
