Description

Technical Field

[0001] The present invention relates to the field of rubidium extraction, in particular to an extraction device and method for recovering rubidium from slag. Background Art

[0002] Rubidium is a soft, silvery-white alkali metal element with an atomic number of 37. It exists in small amounts in the form of compounds in many minerals, mineral waters, and the ashes of many plants, usually accompanied by smaller amounts of cesium.

[0003] Rubidium separation and extraction is typically accomplished using a centrifugal extractor, which extracts two liquid phases, a solution and a solvent, of varying densities, to achieve the transfer of solutes from the solution to the solvent. This centrifuge is characterized by first thoroughly mixing the liquid phases in a centrifugal field to promote solute transfer, followed by separation and discharge of the two phases.

[0004] The existing extraction device for recovering rubidium from slag may cause metal to adhere to the discharge position and cause blockage during use, affecting the discharge speed; therefore, it does not meet the existing needs.

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

[0017] Step A: An extractant is added to the slag containing rubidium metal to form a stock solution. The stock solution is introduced into the interior of the outer liquid barrel through the light phase inlet and the heavy phase inlet. The stock solution then enters the interior of the inner liquid barrel. The servo motor is controlled to drive the rotation shaft, which drives the stirring rod and the dispersion disk to rotate, thereby stirring the stock solution inside the inner liquid barrel. Since rubidium metal has a greater specific gravity than other metals, the rubidium-containing liquid rotates on the inner wall of the inner liquid barrel due to gravity and centrifugal force, while the liquid containing other metals rotates near the rotation shaft, thereby achieving the separation of rubidium from the slag;

[0018] Step B: After rubidium is separated from the slag, the rubidium-containing liquid enters the heavy phase storage chamber through the heavy phase collection chamber, and the liquid containing other metals enters the light phase storage chamber through the light phase collection ring groove. At this time, the liquid at the top may not be completely separated. The separated liquid is returned to the internal liquid barrel through the light phase inlet and the heavy phase inlet through the circulation pipe for a second separation;

[0019] Step C: After the raw liquid has been extracted and separated multiple times, ensure that the liquid containing rubidium is discharged through the heavy phase outlet and the liquid containing other metals is discharged through the light phase outlet;

[0020] Step D: When the stock solution is being extracted, the driving assembly drives the tamping rod to move up and down inside the collection port to stir the liquid entering the collection port to prevent metal from adhering to the collection 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 uses a driving assembly to drive the transmission gear and the driving gear to rotate during slag extraction and separation, thereby driving the driven gear to rotate, so that the upper rack and the lower rack cyclically move up and down in the installation cavity, thereby driving the tamping rod to move in the collection port, thereby preventing metal from adhering to the collection port and causing 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

Through the configuration of the drive assembly 4, when extracting and separating slag, the rotating shaft 203 drives the transmission gear 406 and the driving gear 407 via the transmission belt 410, thereby driving the driven gear 405 to rotate, causing the upper rack 401 and the lower rack 411 to circulate and rise and fall within the mounting cavity 302, thereby driving the ram 404 to move within the collection port 304, preventing metal from adhering to and accumulating in the collection port 304 and causing blockage.

[0048] Working principle: The slag raw liquid 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 raw liquid enters the interior of the inner liquid barrel 201. 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 disk 206 to rotate, thereby stirring the raw liquid inside the inner liquid barrel 201. At this time, the raw liquid will rotate in the inner liquid barrel 201 through the dispersion of the dispersion plate 202 and the dispersion disk 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.

[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. The driven gear 405 drives the upper rack 401 and the lower rack 411 to move up and down in a cycle, so that the tamping rod 404 moves up and down in a cycle 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. 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 liquid 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 uppermost liquid 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 raw liquid has been extracted and separated 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. At the same time, the driving gear 407 will drive the two transmission gears 406 meshing therewith to rotate counterclockwise, and the counterclockwise rotating transmission gear 406 will drive the driven gear 405 meshing therewith to rotate clockwise. Since the upper rack 401 is meshed with the counterclockwise rotating driven gear 405 at this time, the lower rack 411 is in a clockwise state. The clockwise rotating driven gear 405 is at the lower position and is not engaged with the driven gear 405, so that the counterclockwise rotating driven gear 405 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 is fixedly connected to the guide rod 403, when the guide rod 403 deviates, it 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 from the track on one side of the track groove 308, the upper rack 401 remains in meshing with the counterclockwise rotating driven gear 405, while the lower rack 411 will be misaligned with the clockwise rotating driven gear 405; similarly, when the upper rack 401 and the lower rack 411 deviate from the track on the other side of the track groove 308, the lower rack 411 will remain in meshing with the clockwise rotating driven gear 405, while the upper rack 401 will be misaligned with the counterclockwise rotating driven gear 405, so that when the guide rod 403 moves to the position of the upper blocking plate 311, the lower rack 411 and the clockwise rotating driven gear 405 are in a misaligned state, and the clockwise rotating driven gear 405 will not The upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear 405, and the upper rack 401 is engaged with the driven gear Figure 11 , at this time, the driven gear 405 rotating counterclockwise will not push the upper rack 401 to move upward;

[0056] Then, due to the engagement of the lower rack 411 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, thereby releasing the meshing between the upper rack 401 and the driven gear 405, so that the lower rack 411 is driven downward by the driven gear 405 rotating clockwise. 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, thereby preventing damage to the equipment caused by friction between the upper rack 401 and the driven gear 405 rotating counterclockwise due to 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 fixed plate 402 drives the upper rack 401 and the lower rack 411 to move up and down inside the installation cavity 302, thereby driving the tamping rod 404 to move up and down inside the collection port 304, thereby stirring the liquid entering the collection port 304, and preventing metal from adhering to the collection 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 fixed plate 402, so that the tamping rod 404 is prevented from being misaligned with the collecting port 304 when the fixed plate 402 moves laterally.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.

7. The extraction method for recovering rubidium from slag according to claim 6, characterized in that: The following steps are involved: Step A: adding an extractant to slag containing rubidium metal to prepare a stock solution, the stock solution is introduced into the interior of the outer liquid barrel (102) through 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), controlling the servo motor (204) to drive the rotating shaft (203) to rotate, so that the rotating shaft (203) drives the stirring rod (205) and the dispersion disk (206) to rotate, thereby stirring the stock solution inside the inner liquid barrel (201). 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 (201) due to gravity and centrifugal force, and the liquid containing other metals rotates at a position close to the rotating shaft (203), thereby achieving separation of rubidium from the slag; Step B: After rubidium is separated from the slag, the liquid containing rubidium enters the heavy phase storage chamber (103) through the heavy phase collection chamber (306), and the liquid containing other metals enters the light phase storage chamber (104) through the light phase collection ring groove (305). 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; Step C: After the raw liquid 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); Step D: When the raw liquid is being extracted, the driving assembly (4) drives the tamping rod (404) to move up and down inside the collecting port (304), stirring the liquid entering the collecting port (304) to prevent metal from adhering to the collecting port (304) and causing blockage; Step E: The top end of the tamping rod (404) slides in the sliding groove at the bottom end of the fixed plate (402), so that the tamping rod (404) and the collecting port (304) are prevented from being misaligned when the fixed plate (402) moves laterally.
