Description

Technical Field

[0001] The invention relates to the technical field of separation and extraction, in particular to a device for extracting and separating rubidium and cesium from lithium slag. Background Art

[0002] The current process of extracting rubidium and cesium from lithium carbonate waste residue is to weigh a specified weight of the material containing rubidium and cesium metals, then dissolve the weighed material to obtain a solution containing rubidium and cesium substances. The solution containing rubidium and cesium substances is then subjected to solid-liquid separation, and the solid substance obtained is finally dried.

[0003] The height and width of the current extraction and separation equipment are basically fixed, but the flow rate and flow rate of the mixed impurity solution containing rubidium and cesium metals are constantly changing during the extraction and separation process, because the flow rate is not fixed when the solution is transported. Such a design will cause certain problems. First, when the flow rate of the mixed solution is too small, the mixed solution cannot fully contact the surface of the filter disc, resulting in some filter holes on the filter disc being idle, while some filter holes are always in working state and are prone to wear and blockage, and the filter disc cannot be fully and reasonably utilized. Secondly, when the flow rate of the mixed solution is too large, it is easy to cause problems such as insufficient internal space of the separation tower and insufficient filtration area of ​​the filter disc, which leads to untimely filtration.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 9 , a technical solution provided by the present invention:

[0033] A device for extracting and separating rubidium and cesium from lithium slag comprises a base 1 and a separation tower shell arranged on the base 1, wherein the separation tower shell is composed of a fixed frame 2 and a movable frame 3. The fixed frame 2 is fixedly mounted on the base 1, and the top and right sides of the fixed frame 2 are both provided with openings, and the top and left sides of the movable frame 3 are provided with openings, and a slot is provided on the right side of the fixed frame 2, and the left side of the movable frame 3 is inserted into the slot, so that a chamber for mixed solution treatment is formed between the movable frame 3 and the fixed frame 2. The movable frame 3 can move left and right relative to the fixed frame 2, thereby changing the volume of the internal chamber of the mixed solution treatment separation tower to adapt to different water volumes.

[0034] Furthermore, a liquid inlet mechanism 4 is provided on the fixed frame 2, and the liquid inlet mechanism 4 is used to transport the mixed solution of lithium slag into the separation tower. A filtering mechanism 5 is provided between the fixed frame 2 and the movable frame 3, and the filtering mechanism 5 is used to intercept the solid impurities in the mixed solution to achieve solid-liquid separation. An adaptive mechanism 6 is connected to the liquid inlet mechanism 4, and the liquid inlet mechanism 4 can drive the adaptive mechanism 6 to operate, so that the movable frame 3 moves horizontally, so that the size of the internal chamber of the separation tower automatically changes with the flow rate of the mixed solution.

[0035] In this embodiment, two fixed plates 9 are fixedly connected to the base 1, a guide rod 8 is arranged between the two fixed plates 9, and the two ends of the guide rod 8 are respectively fixedly connected to the two fixed plates 9. A movable plate 10 is slidably connected to the guide rod 8, and the movable plate 10 is fixedly connected to the movable frame 3. A reset spring 7 is sleeved on the guide rod 8, and the two ends of the reset spring 7 are respectively fixedly connected to the fixed plate 9 and one of the movable plates 10. The reset spring 7 is used to drive the movable frame 3 to automatically reset.

[0036] In this embodiment, the liquid inlet mechanism 4 includes a support frame 41, which is fixedly connected to the fixed frame 2, and a fixed cylinder 42 is fixedly connected to the support frame 41. The top of the fixed cylinder 42 is connected with an introduction pipe 43, which is used to introduce the external mixed solution into the separation tower. The outer circumference of the fixed cylinder 42 is respectively connected with an upper liquid inlet pipe 44 and a lower liquid inlet pipe 45, and the water outlet ends of the upper liquid inlet pipe 44 and the lower liquid inlet pipe 45 are both downward, which are used to discharge the mixed solution in the fixed cylinder 42 into the separation tower. The fixed cylinder 42 is connected with a telescopic hose 46, one end of the telescopic hose 46 is fixedly connected to the fixed cylinder 42, and the other end is fixedly connected to the inner wall of the movable frame 3. When the movable frame 3 moves to the right, the telescopic hose 46 can be straightened, so that the horizontal distance between the two ends of the telescopic hose 46 increases. The telescopic hose 46 is provided with a plurality of water outlet holes 461, and the plurality of water outlet holes 461 are distributed at equal distances along the length direction of the telescopic hose 46. When the telescopic hose 46 is straightened, the position of the water outlet 461 will move to the right, so that the outflow position of the mixed solution moves to the right to adapt to the size change of the internal space of the separation tower.

[0037] In this embodiment, the filter mechanism 5 includes an inclined filter plate 51, the left end of which is hinged to the inner wall of the fixed frame 2, the right end of which is higher than the left end, and the left end of which is hinged to a horizontal filter plate 52. The filter mechanism 5 also includes a sliding baffle 53, which is slidably connected to the inner wall of the movable frame 3, and the sliding baffle 53 is movably sleeved on the horizontal filter plate 52. Specifically, a through groove for inserting the horizontal filter plate 52 is provided on the sliding baffle 53, and the horizontal filter plate 52 is movably inserted in the through groove, so that when the sliding baffle 53 moves up and down, it can synchronously drive the horizontal filter plate 52 to move up and down, and the sliding baffle 53 can move left and right on the surface of the horizontal filter plate 52. When the horizontal filter plate 52 moves up and down, the inclined filter plate 51 can be rotated around the hinge point at its left end, so that the inclination angle of the inclined filter plate 51 changes. The increase in the inclination of the inclined filter plate 51 is conducive to the flow of the mixed solution on its surface, so that when the water flow is small, the filter holes on the inclined filter plate 51 can also be fully utilized, avoiding the situation where some filter holes are idle due to too small water flow, while some filter holes are always in working state, thereby improving the utilization rate of the filter plate. When the inclination of the inclined filter plate 51 decreases, its horizontal distance will increase, so that after the water volume increases, the water flow can contact the filter plate more evenly.

[0038] It is worth noting that a clearance opening 31 is provided on the movable frame 3, and the sliding baffle 53 is used to close the clearance opening 31. By providing the clearance opening 31, the horizontal filter plate 52 can move up and down.

[0039] Furthermore, a transmission assembly 54 is provided on the sliding baffle 53 for controlling the sliding baffle 53 to move up and down.

[0040] Specifically, the transmission assembly 54 includes a fixed block 541, which is fixedly connected to the movable plate 10, and a connecting shaft 542 is rotatably connected to the fixed block 541, and a large gear 543 and a small gear 545 are fixedly connected to the connecting shaft 542. The sliding baffle 53 is provided with teeth 544 distributed in a straight line at equal distances, and the teeth 544 are meshed with the large gear 543. The rotation of the large gear 543 can drive the teeth 544 to move up and down, thereby driving the sliding baffle 53 to move up and down. The small gear 545 is meshed with a fixed rack 546, and the fixed rack 546 is fixedly connected to the fixed plate 9. The diameter of the small gear 545 is smaller than the diameter of the large gear 543. The large gear 543 is driven to rotate by the small gear 545, so as to achieve the purpose of increasing the motion stroke. When the movable frame 3 moves to the right, it will simultaneously drive the sliding baffle 53, the fixed block 541, the connecting shaft 542 and other structures to move to the right, and the connecting shaft 542 drives the small gear 545 and the large gear 543 to move to the right. Since the pinion 545 is meshed with the fixed rack 546 and the fixed rack 546 cannot move, the pinion 545 rotates when it moves to the right, and the rotation drives the connecting shaft 542 to rotate. The connecting shaft 542 drives the teeth 544 to move downward through the large gear 543, so that the sliding baffle 53 automatically moves downward.

[0041] In this embodiment, the adaptive mechanism 6 includes a piston 61, the surface of the piston 61 is slidably connected to the inner wall of the fixed cylinder 42, when the water flow increases, the water pressure in the fixed cylinder 42 increases, and the piston 61 can be pushed downward, so that the adaptive mechanism 6 automatically operates. The bottom end of the piston 61 is fixedly connected with a slide bar 62, the surface of the slide bar 62 is slidably connected to the inner wall of the fixed cylinder 42, and a support spring 63 is sleeved on the slide bar 62, and the two ends of the support spring 63 are respectively fixedly connected to the fixed cylinder 42 and the piston 61, and the support spring 63 is used to support the piston 61, and can drive the piston 61 to reset after the water flow decreases. The bottom end of the slide rod 62 passes through the fixed tube 42 and is fixedly connected to the first connecting rod 64, the first connecting rod 64 is fixedly connected to the second connecting rod 65, the top end of the second connecting rod 65 is fixedly connected to the driving plate 66, and the driving plate 66 is fixedly connected to the first pull rope 67. When the piston 61 moves downward, the first connecting rod 64 can be driven to move downward synchronously through the slide rod 62, the first connecting rod 64 drives the driving plate 66 to move downward through the second connecting rod 65, and the driving plate 66 pulls the first pull rope 67.

[0042] Furthermore, the adaptive mechanism 6 also includes a support plate 612, which is fixedly connected to the fixed plate 9, and a reel 69 is rotatably connected to the support plate 612, and a first reel 68 and a second reel 610 are fixedly connected to the reel 69, and the first pull rope 67 is wound on the first reel 68. A second pull rope 611 is wound on the second reel 610, and one end of the second pull rope 611 is fixedly connected to the movable plate 10. When the left end of the first pull rope 67 is pulled, the first reel 68 is driven to rotate counterclockwise to unwind the first pull rope 67. The first reel 68 drives the second reel 610 to rotate synchronously through the reel 69, and the second reel 610 rotates counterclockwise to reel the second pull rope 611, so that the left end of the second pull rope 611 moves to the right and pulls the movable plate 10 to the right. The diameter of the first winding wheel 68 is smaller than that of the second winding wheel 610 , which can increase the movement stroke, so that the piston 61 moves downward a smaller distance and can drive the movable plate 10 to move rightward a larger distance.

[0043] In addition, the adaptive mechanism 6 also includes a first guide wheel 613 and a second guide wheel 615. The first guide wheel 613 and the second guide wheel 615 are both in contact with the first pull rope 67 and are used to guide the first pull rope 67. The first guide wheel 613 is rotatably connected to a connecting rod 614, and the connecting rod 614 is fixedly connected to the support frame 41 for supporting the first guide wheel 613. The second guide wheel 615 is rotatably connected to a mounting plate 616, and the mounting plate 616 is fixedly connected to the fixing plate 9 for supporting the second guide wheel 615.

[0044] Working principle: The lithium slag mixed solution containing rubidium and cesium flows into the fixed cylinder 42 from the inlet pipe 43, and flows out of the liquid inlet mechanism 4 through the upper liquid inlet pipe 44 and the telescopic hose 46. In this process, if the flow rate of the mixed solution increases, the water pressure in the fixed cylinder 42 will increase, and the piston 61 will move downward under the push of the water pressure. Figure 4 shown.

[0045] The piston 61 drives the first connecting rod 64 to move downward through the sliding rod 62, and the first connecting rod 64 drives the driving plate 66 to move downward through the second connecting rod 65. The driving plate 66 pulls one end of the first pull rope 67 downward. Since the other end of the first pull rope 67 is wound around the first winding wheel 68, the first pull rope 67 drives the first winding wheel 68 to rotate counterclockwise during this process. The first winding wheel 68 drives the second winding wheel 610 to rotate synchronously through the winding shaft 69, and the second winding wheel 610 rotates counterclockwise to reel in the second pull rope 611, so that one end of the second pull rope 611 pulls the movable plate 10 to the right. The movable plate 10 drives the movable frame 3 to move to the right, so that the internal space of the separation tower becomes larger.

[0046] When the movable frame 3 moves to the right, the sliding baffle 53 inside it will be synchronously driven to move to the right. At the same time, the movable plate 10 will drive the connecting shaft 542 to move to the right through the fixed block 541, and the connecting shaft 542 will simultaneously drive the small gear 545 and the large gear 543 fixed thereon to move to the right. Since the small gear 545 is meshed with the fixed rack 546, and the fixed rack 546 cannot move, the small gear 545 will rotate in the process of moving to the right. The small gear 545 drives the large gear 543 to rotate counterclockwise through the connecting shaft 542, and the large gear 543 drives the teeth 544 to move downward through the meshing, thereby driving the sliding baffle 53 to move downward. When the sliding baffle 53 moves downward, it will synchronously drive the horizontal filter plate 52 to move downward, and the horizontal filter plate 52 drives the right end of the inclined filter plate 51 to move downward, thereby enabling the inclined filter plate 51 to rotate clockwise around the hinge point at its left end. Since the horizontal filter plate 52 can slide left and right inside the sliding baffle 53, there will be no motion interference in this process. When the sliding baffle 53 moves downward to a certain position, the bottom of the horizontal filter plate 52 will contact the bottom wall inside the yielding opening 31, and the inclined filter plate 51 is still in an inclined state. Then the movable frame 3 continues to move to the right, and the pinion 545 will disengage from the fixed rack 546, so that the sliding baffle 53 will not continue to move downward, and the inclination angle of the inclined filter plate 51 will not continue to change. When the sliding baffle 53 moves to the right, it will slide on the surface of the horizontal filter plate 52, so that the filter holes on the horizontal filter plate 52 enter the internal chamber of the separation tower. The horizontal filter plate 52 is used in conjunction with the inclined filter plate 51 to separate and filter the mixed solution after the flow rate increases, avoiding the occurrence of untimely filtration.

[0047] In addition, when the movable frame 3 moves to the right, one end of the telescopic hose 46 will be driven to move to the right, so that the telescopic hose 46 is straightened and the outflow position of the mixed solution moves to the right to adapt to the size change of the internal space of the separation tower.

[0048] When the flow rate of the mixed solution decreases, the piston 61 moves upward under the elastic force of the support spring 63, and the movable frame 3 moves to the left under the elastic force of the return spring 7, so that the adaptive mechanism 6 and the transmission assembly 54 run in the opposite direction, the internal space of the separation tower becomes smaller, the horizontal filter plate 52 moves outside the movable frame 3, and the slope of the inclined filter plate 51 increases, so that the mixed solution can be processed centrally. Finally, a solution without lithium slag is obtained, the lithium slag is fully filtered, and then the crystalline rubidium-cesium material is obtained after drying.
