[0016] An extraction method for recovering rubidium from slag by an extraction device comprises the following steps:

Since the specific gravity of rubidium metal is greater than that of other metals, the liquid containing rubidium metal rotates on the inner wall of the inner liquid barrel due to gravity and centrifugal force, and the liquid containing other metals rotates at a position close to the rotating shaft, thereby realizing the separation of rubidium in the slag;

[0020] Step D: When the stock solution is being extracted, the driving assembly drives the tamping rod to move up and down inside the collecting port to stir the liquid entering the collecting port to prevent metal from adhering to the collecting port and causing blockage;

[0021] Step E: The top end of the tamping rod slides in the sliding groove at the bottom end of the fixed plate to prevent the tamping rod from being misaligned with the collecting port when the fixed plate moves laterally.

[0022] The beneficial effects of the present invention are:

[0023] The present invention drives the transmission gear and the driving gear to rotate when extracting and separating the slag, and then drives the driven gear to rotate, so that the upper rack and the lower rack circulate and move up and down in the installation cavity, thereby driving the tamping rod to move in the collection port, avoiding the metal adhesion in the collection port to cause blockage;

[0024] The present invention cooperates with the dispersion plate and the stirring rod so that when separating, the slag solution is initially separated by the dispersion plate, and then the stirring rod is used to accelerate the separation of the metal. The dispersion plate further disperses the slag solution, thereby improving the separation efficiency of the metal. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Working principle: The slag stock solution containing metals such as rubidium is introduced into the interior of the outer liquid barrel 102 from the light phase inlet 107 and the heavy phase inlet 108, and then the stock solution enters the interior of the inner liquid barrel 201, and the servo motor 204 is controlled to drive the rotating shaft 203 to rotate, so that the rotating shaft 203 drives the stirring rod 205 and the dispersion plate 206 to rotate, thereby stirring the stock solution inside the inner liquid barrel 201. At this time, the stock solution will rotate in the inner liquid barrel 201 through the dispersion of the dispersion plate 202 and the dispersion plate 206, and under the action of centrifugal force, and diffuse upward to the bottom end of the discharge platform 301. Since the specific gravity of rubidium metal is greater than that of other metals, the rubidium-containing solution rotates close to the inner wall of the inner liquid barrel 201 due to the greater gravity and centrifugal force, and the solution containing other metals will rotate at a position closer to the rotating shaft 203, thereby realizing the separation of rubidium in the slag.

[0049] The servo motor 204 drives the rotating shaft 203 to rotate, and drives the two transmission gears 406 and the driving gear 407 to rotate clockwise through the transmission belt 410, thereby driving the driven gear 405 to rotate, and the driven gear 405 drives the upper rack 401 and the lower rack 411 to cyclically rise and fall, so that the tamping rod 404 cyclically rises and falls in the collection port 304, stirring the liquid entering the collection port 304 to prevent substances from adhering to the collection port 304 and causing blockage.

[0050] An extraction method for recovering rubidium from slag using an extraction device, the extraction method comprising the following steps:

[0051] Step A: The slag stock solution containing rubidium and other metals is introduced into the interior of the outer liquid barrel 102 from the light phase inlet 107 and the heavy phase inlet 108, and then the stock solution enters the interior of the inner liquid barrel 201, and the servo motor 204 is controlled to drive the rotating shaft 203 to rotate, so that the rotating shaft 203 drives the stirring rod 205 and the dispersion plate 206 to rotate, thereby stirring the stock solution inside the inner liquid barrel 201. At this time, the stock solution will rotate in the inner liquid barrel 201 through the dispersion of the dispersion plate 202 and the dispersion plate 206, and under the action of centrifugal force, and diffuse upward to the bottom end of the discharge platform 301. Since the specific gravity of rubidium metal is greater than that of other metals, the rubidium-containing solution rotates close to the inner wall of the inner liquid barrel 201 due to the greater gravity and centrifugal force, and the solution containing other metals will rotate closer to the rotating shaft 203, thereby realizing the separation of rubidium in the slag.

[0052] Step B: After rubidium is separated from the slag, the rubidium-containing liquid will enter the heavy phase collection chamber 306 through the collection port 304 and then enter the heavy phase storage chamber 103. The liquids of other metals will enter the light phase collection ring groove 305 through the collection port 304 and then enter the interior of the light phase storage chamber 104. At this time, the liquid at the top may not be completely separated. The separated liquid is returned to the internal liquid barrel 201 through the light phase inlet 107 and the heavy phase inlet 108 through the circulation pipe for a second separation.

[0053] Step C: After the stock solution has been extracted and separated for multiple times, ensure that the liquid containing rubidium is discharged from the device through the heavy phase outlet 106, and the liquid containing other metals is discharged from the device through the light phase outlet 105;

[0054] Step D: When the stock solution is being extracted, the rotating shaft 203 rotates clockwise, and the transmission belt 410 drives the two transmission gears 406 and the driving gear 407 to rotate clockwise respectively. At this time, the two transmission gears 406 will drive the driven gear 405 meshing therewith to rotate counterclockwise, and at the same time, the driving gear 407 will drive the two transmission gears 406 meshing therewith to rotate counterclockwise, and the driven gear 405 meshing therewith will be driven to rotate clockwise through the counterclockwise rotating transmission gear 406. At this time, the upper rack 401 is in meshing state with the counterclockwise rotating driven gear 405, and at the same time, the lower rack 411 is in a clockwise state. The driven gear 405 rotates clockwise and is not meshed with the driven gear 405, so that the driven gear 405 rotates counterclockwise and pushes the upper rack 401 to move upward. When the upper rack 401 moves upward, the guide rod 403 moves upward in the track groove 308. When the guide rod 403 moves upward to the position of the lower blocking plate 311, it is blocked by the lower blocking plate 311 and deviates to one side. Since the fixing plate 402 and the guide rod 403 are fixedly connected, the guide rod 403 deviates and drives the upper rack 401 and the lower rack 411 to deviate at the same time through the fixing plate 402.

[0055] When the upper rack 401 and the lower rack 411 deviate toward the track on one side of the track groove 308, the upper rack 401 remains in meshing with the driven gear 405 rotating counterclockwise, while the lower rack 411 is misaligned with the driven gear 405 rotating clockwise; similarly, when the upper rack 401 and the lower rack 411 deviate toward the track on the other side of the track groove 308, the lower rack 411 remains in meshing with the driven gear 405 rotating clockwise, while the upper rack 401 is misaligned with the driven gear 405 rotating counterclockwise, so that when the guide rod 403 moves to the position of the upper blocking plate 311, the lower rack 411 is in a misaligned state with the driven gear 405 rotating clockwise, and the driven gear 405 rotating clockwise will not The lower rack 411 is pushed to prevent the upper rack 401 from getting stuck; when the guide rod 403 continues to move upward and hits the inclined surface 312 on the surface of the upper blocking plate 311, the upper blocking plate 311 is retracted into the spring groove 309. At this time, the guide rod 403 will move upward to the uppermost position of the track groove 308. At this time, due to the lateral displacement of the guide rod 403, the fixing plate 402 and the upper rack 401 and the lower rack 411 will be driven to move lateral at the same time, so that the lower rack 411 is meshed with the driven gear 405 rotating clockwise. Since the upper rack 401 is at the uppermost position at this time, the upper rack 401 is located above the driven gear 405 rotating counterclockwise. Fig.11 At this time, the driven gear 405 rotating counterclockwise will not push the upper rack 401 to move upward;

[0056] Subsequently, since the lower rack 411 meshes with the driven gear 405 rotating clockwise, the fixed plate 402, the upper rack 401 and the lower rack 411 are driven to move downward. When the lower rack 411 drives the upper rack 401 to move downward, the guide rod 403 on the lower rack 411 is blocked by the upper blocking plate 311 and deviates to the specified track of the track groove 308, so that the upper rack 401 and the driven gear 405 are disengaged, so that the lower rack 411 is driven by the driven gear 405 rotating clockwise and pushed downward. At this time, the upper rack 401 is located above the driven gear 405, and the gear outer bevel groove 408 and the rack outer bevel groove 409 on the outer surface of the upper rack 401 are in contact with each other. When the rack 401 descends, it will deviate along the track direction of the track groove 308 due to the angle between the outer inclined groove 409 of the rack and the outer inclined groove 408 of the gear, so as to avoid the damage of the equipment caused by the friction between the upper rack 401 and the driven gear 405 rotating counterclockwise due to the lateral movement; when the guide rod 403 falls to the lowest position of the track groove 308, the upper rack 401 will mesh with the driven gear 405, and the operation will be repeated, so that the fixing plate 402 drives the upper rack 401 and the lower rack 411 to move up and down inside the installation cavity 302, and then drives the tamping rod 404 to move up and down inside the collecting port 304, so as to stir the liquid entering the collecting port 304, and avoid the metal adhering to the collecting port 304 and causing blockage;

[0057] Step E: The top end of the tamping rod 404 slides in the sliding groove at the bottom end of the fixing plate 402, so that when the fixing plate 402 moves laterally, the tamping rod 404 is prevented from being misaligned with the collecting port 304.

[0058] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
