Description

Technical Field

[0001] This invention relates to the field of lithium extraction technology, specifically to column chromatography equipment for lithium extraction and its usage method. Background Technology

[0002] The deep purification of fluorite and lepidolite is achieved through synergistic flotation. Fluorite and calcium silicate gangue minerals are separated by stepwise enhanced flotation, with the fluorite concentrate grade reaching 90%. Alternatively, high-quality anhydrous hydrofluoric acid can be prepared by combining fluorite beneficiation and chemical treatment. Lepidolite is selectively enriched based on the synergistic enhancement of multiple fields such as flotation, magnetic separation and gravity separation. Alternatively, lepidolite concentrate can be selectively extracted by alkaline leaching, with the Li2O enrichment ratio reaching 3-4 and the lithium leaching rate reaching 90%.

[0003] Most existing lithium extraction methods involve water immersion followed by flotation, while chromatographic columns are the main component of gel chromatography technology. They are generally made of glass or plexiglass tubes and are a chromatographic method that separates components in a sample mixture based on their different partition coefficients in the stationary and mobile phases.

[0004] Existing column chromatography equipment requires filling its interior with soft silica gel during lithium extraction, followed by elution with a special solvent. The eluted chromatographic solution needs to be manually changed into different containers, which is time-consuming and greatly extends the chromatography production cycle. In addition, to prevent the volatility of some substances and external contamination, end caps are usually installed at the end. However, the opening and closing of the end caps is extremely inconvenient due to manual operation. Summary of the Invention

A pair of first magnetic blocks that attract each other are provided between the second trapezoidal block and the first trapezoidal block.

[0018] As a preferred technical solution of the column chromatography apparatus for lithium extraction of the present invention, a rack extending to the outside of the chromatography tube body slides inside the tube body. A magnetic baffle that contacts a sealing sleeve is fixed on the side of the rack near the outer wall of the chromatography tube body. A pair of mutually attracted second magnetic blocks are arranged between the magnetic baffle and the sealing sleeve.

An movable slot matching the inner conical block is opened inside the chromatography tube body, and the movable slot extends to the inner wall of the chromatography tube body. The conical spiral wire is made of iron and has a certain degree of elasticity.

[0019] The preferred technical solution for using the column chromatography equipment for lithium extraction according to the present invention is as follows:

[0020] Step 1: When extracting lithium from materials that need to be chromatographically analyzed, a soft silica gel mixture can be added into the chromatography tube body, and then the material to be chromatographically analyzed can be added into the chromatography tube body.

[0021] Step 2: At this time, the overall weight inside the chromatography tube increases, and the chromatography tube slides inside the sliding sleeve, causing the tube connecting rod to slide. At this time, with the cooperation of the transmission component and the collection component, the protective covers sliding on the top of multiple collection boxes can be flipped and slid into the collection box, so that the collection box is in the open state.

[0022] Step 3: At this point, elution solvent can be injected into one of the chromatography tubes. The overall weight of the chromatography tube gradually decreases from high to low. The material precipitated inside the tube enters the collection box through the discharge hopper. When the weight inside the chromatography tube no longer changes, the quantitative disk can be rotated regularly at a specified angle with the help of the gravity transmission component. Then, with the connection of the collection plate, multiple collection boxes can be rotated regularly. At this time, elution solvent can be injected into the remaining chromatography tubes in sequence to achieve the effect of centralized collection of different chromatographic materials.

[0023] Step 4: When the chromatography is complete, the drive motor can be started. With the cooperation of the separation components, the multiple sets of push plates can be gradually moved away from each other. With the cooperation of the discharge components, the sealing sleeve can be separated from the outer shell of the chromatography tube body, which can facilitate the cleaning of the inner wall of the chromatography tube body.

[0024] Step 5: At the same time, the magnetic baffle can be pulled to slide. With the cooperation of the rack, gear and winding cone, the winding cone can be rotated, and the conical spiral wire can slide inside the chromatography tube body. The outer cone block can be inserted into the soft silica gel, and the soft silica gel can be pushed out to the bottom of the chromatography tube body, which can facilitate the removal of the soft silica gel.

[0025] In summary, the present invention has the following main beneficial effects:

[0026] 1. This invention involves introducing a soft silica gel mixture into the interior of a chromatography tube, followed by the introduction of the material to be chromatographically analyzed into the tube. Elution solvent is then injected into one of the chromatography tubes, causing the overall weight of the tube to decrease from high to low. With the assistance of a gravity transmission component, this drives a quantitative disc to rotate regularly at a quantitative angle. Subsequently, with the connection of a collection plate, multiple collection boxes rotate regularly. Elution solvent is then injected into the remaining chromatography columns sequentially. As the weight inside the chromatography columns decreases, the collection boxes rotate regularly to collect the materials, achieving the effect of centralized collection of different chromatographic materials.

[0027] 2. This invention involves introducing a soft silica gel mixture into the chromatography tube body and injecting an elution solvent into one of the chromatography tube bodies. During this process, the total weight inside the chromatography tube body increases from low to high. With the cooperation of the transmission component, a negative pressure is created inside the gas chamber body, which in turn pushes the telescopic piston rod inside the piston cylinder to slide. This pushes the transmission cylinder at the bottom of the telescopic piston rod to slide. At this time, with the cooperation of the collection component, the protective caps at the ends of multiple collection boxes flip over, allowing the collection boxes to be opened for easy material collection. When the chromatography ends, with the cooperation of the separation component and the discharge component, the overall weight of the chromatography column body decreases, and the gas chamber body returns to its original position and expands with the cooperation of the transmission component. With the cooperation of the collection component, the multiple protective caps flip over and are relatively flush with the ends of the collection boxes, achieving the purpose of protection and effectively preventing problems such as volatilization and dispersion of the collected material.

[0028] 3. This invention starts the drive motor, which in turn drives the rotating shaft at its end to rotate. At this time, with the connection of the sector plate, the arc-shaped turntable fixedly connected to the rotating cylinder rotates. At this time, with the cooperation of the arc-shaped groove, the straight groove plate and the straight sliding groove, multiple sets of sliding rods in the groove can slide in a straight line. Then, with the connection of the sliding rod side rod, the outer push plate can slide and then push the extension rod to slide. At this time, the first trapezoidal block can push the second trapezoidal block to slide inside the outer guide ring, which can separate the sealing sleeve from the outer shell of the chromatography tube body, thus facilitating the cleaning of the inner wall of the chromatography column.

[0029] 4. By starting the drive motor, the present invention can drive the rotating shaft at its end to rotate. At this time, with the cooperation of the separation component, the sealing sleeve can be separated from the outer shell of the chromatography tube body. At the same time, the magnetic baffle can be pulled, and the rack drives the gear to rotate, which in turn drives the winding conical disk to rotate. This allows the conical spiral wire to slide inside the chromatography column body, allowing it to be inserted into the soft silicone. The soft silicone can be pushed out to the bottom of the chromatography tube body, which can facilitate the removal of the soft silicone. Attached Figure Description

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0054] The embodiments of the present invention will now be described.

[0055] Column chromatography equipment used for lithium extraction, such as Figures 1 to 16 As shown, the system includes a column chromatography equipment assembly 100, a chromatography component 200 at the top of the column chromatography equipment assembly 100, a gravity transmission component 300 extending into the interior of the column chromatography equipment assembly 100 on the outside of the chromatography component 200, a transmission component 400 extending downward therefrom inside the column chromatography equipment assembly 100, and a collection component 500 extending downward therefrom below the column chromatography equipment assembly 100.

[0056] The column chromatography equipment assembly 100 includes a fixed support 110, with multiple sets of support columns 120 fixed inside the fixed support 110, and a central fixed plate 130 fixed between the multiple sets of support columns 120.

[0057] The chromatography assembly 200 includes multiple sets of chromatography tube bodies 210, a connector 220 is fixed at the top of the central fixing plate 130, and multiple sets of sliding sleeves 230 are fixed on the outer wall of the connector 220, and the sliding sleeves 230 are sleeved on the outer wall of the chromatography tube body 210.

[0058] The gravity transmission assembly 300 includes multiple sets of tube connecting rods 310 fixed to the outer wall of multiple sets of chromatography tube bodies 210. A negative pressure piston 320 is fixed to the bottom end of each tube connecting rod 310. A negative pressure cylinder 330 matching the negative pressure piston 320 is provided inside the central fixed disk 130. A reciprocating piston 340 slides on the inner wall of the other end of the negative pressure cylinder 330. A telescopic rotating rod 350 rotates on one end of the reciprocating piston 340 located outside the negative pressure cylinder 330. A reciprocating turntable 360 ​​rotates between the multiple sets of telescopic rotating rods 350, and the reciprocating turntable 360 ​​is rotatably connected to the inner wall of the central fixed disk 130. An inner spiral groove 361 is provided on the inner wall of the reciprocating turntable 360. A reciprocating slide cylinder 370 slides on the inner wall of the central fixed disk and inside the reciprocating turntable 360. A first guide rod 371 is fixed to the outer wall of the reciprocating slide cylinder 370 and contacts the inner wall of the inner spiral groove 361. A second guide rod 372 is fixed to the inner wall of the reciprocating slide cylinder 370. A metering drum 380 rotates inside the reciprocating slide cylinder 370. A metering groove 381 matching the second guide rod 372 is opened on the outer wall of the metering drum 380. A reset rotating rod 382 that contacts the second guide rod 372 rotates inside the metering groove 381. A reset stop rod 383 is fixed to the inner wall of the metering groove 381 and below the reset rotating rod 382. A reset torsion spring is fixed between the reset rotating rod 382 and the metering groove 381. A metering disk 390 is fixed to the bottom end of the metering drum 380 and the metering disk 390 is rotatably connected to the bottom end of the central fixed disk 130.

[0059] The collection component 500 includes a collection plate 510 fixed to the bottom of the metering plate 390, and multiple collection boxes 520 fixed to the top of the collection plate 510.

[0060] The negative pressure cylinder 330 is equipped with a pressure relief valve 331 at its top. The negative pressure cylinder 330 has a reciprocating groove inside that matches the reciprocating piston 340, and the diameter of the reciprocating groove is larger than the diameter of the pressure relief valve 331. The sliding sleeve 230 has a movable groove inside that matches the chromatography tube body 210. Multiple sets of telescopic rotating rods 350 are arranged in a ring array on the outer wall of the reciprocating turntable 360. The central fixed plate 130 has a first groove inside that matches the reciprocating slide cylinder 370. The top of the quantitative plate 390 has a second groove inside that matches the central fixed plate 130. The quantitative groove 381 has multiple sets of Z-shaped grooves inside, and the number of multiple sets of Z-shaped grooves is equal to the number of multiple sets of collection boxes 520. A negative pressure spring is fixed between the reciprocating piston 340 and the inner wall of the negative pressure cylinder 330.

[0061] When lithium extraction is required from the material to be chromatographically analyzed, a soft silica gel mixture is introduced into the chromatography tube body 210, followed by the material to be chromatographically analyzed. During this process, the overall weight of the chromatography tube body 210 increases. At this point, an elution solvent can be injected into one of the chromatography tube bodies 210, causing a reaction within it. The overall weight of the chromatography tube body 210 then gradually decreases. Meanwhile, the chromatography tube body 210 slides within the sliding sleeve 230, which in turn causes the tube connecting rod 310 fixed to the outer wall of the chromatography tube body 210 to slide, thus... The negative pressure piston 320, fixed at its bottom, slides inside the negative pressure cylinder 330. At this time, negative pressure exists inside the negative pressure cylinder 330, which pushes the reciprocating piston 340 to slide inside the negative pressure cylinder 330. This pushes the telescopic rotating rod 350, rotatably connected to the reciprocating piston 340, to rotate around its contact position with the reciprocating turntable 360. This rotation of the reciprocating turntable 360 ​​causes the first guide rod 371, fixed to the outer wall of the reciprocating slide cylinder 370, to slide inside the inner spiral groove 361. The rotation of the reciprocating turntable 360 ​​pushes the reciprocating slide cylinder 370 to slide. At this time, the first guide rod 371, fixed to the outer wall of the reciprocating slide cylinder 370... The second guide rod 372 can slide inside the quantitative groove 381 opened on the outer wall of the quantitative rotating cylinder 380. When the second guide rod 372 slides above the reset rotating rod 382, ​​it can push the reset rotating rod 382 to rotate and compress the reset torsion spring. It can slide below the reset rotating rod 382. When the reset rotating rod 382 is completely separated from the second guide rod 372, the reset rotating rod 382 can be reset under the action of the reset torsion spring. When the reaction inside the chromatography tube body 210 stops, since the orifice of the pressure relief valve 331 is smaller than the orifice of the reciprocating groove, the reciprocating piston 340 can be reset under the action of the negative pressure spring. During this process, the second guide rod 372 can slide along the bottom end of the reset rotating rod 382 inside the quantitative chute 381, which can push the quantitative rotating cylinder 380 to rotate quantitatively, thereby driving the quantitative disk 390 to rotate. The rotation of the quantitative disk 390 can drive the multiple sets of collection boxes 520 fixed at the top of the collection plate 510 to make circular motion. At this time, the remaining chromatography tube body 210 can be injected with elution solvent in sequence to perform chromatography on the materials that need to be chromatographic. As the weight inside the chromatography column decreases, the collection boxes 520 rotate regularly to collect, thereby achieving the effect of centralized collection of different chromatographic materials.

[0062] Please refer to this carefully. Figure 3 , Figure 6 , Figure 11 , Figure 12 as well as Figure 13The transmission assembly 400 includes a side fixing rod 410 fixed to the outer wall of the tube connecting rod 310, a transmission rotating rod 420 rotatably mounted inside the central fixing disk 130 and located on one side of the side fixing rod 410, a transmission torsion spring 421 fixed between the transmission rotating rod 420 and the inner wall of the central fixing disk 130, a transmission slider 430 fixed to the outer wall of the transmission rotating rod 420, and a lever 422 fixed at the top of the transmission rotating rod 420 in contact with the side fixing rod 410. A transmission slide plate 440 slides on the outer wall of the airbag 30. An airbag push plate 450 is fixed to the other end of the transmission slide plate 440. An airbag body 460 is fixed inside the central fixed plate 130 and located between multiple sets of transmission slide plates 440. The airbag push plate 450 is in contact with the outer wall of the airbag body 460. A piston cylinder 470 connected to the airbag body 460 is fixed inside the central fixed plate 130. A telescopic piston rod 480 slides on the inner wall of the piston cylinder 470. A stop plate is fixed to the bottom of the rod 480. A transmission cylinder 490 that rotates inside the metering disc 390 and contacts the top of the stop plate is rotatably connected. Multiple sets of connecting slide rods 540 slide inside the collecting plate 510, and the multiple sets of connecting slide rods 540 are arranged in a ring array. A connecting rotating rod 530 rotates between the top of the connecting slide rod 540 and the outer wall of the transmission cylinder 490. A connecting push rod 550 rotates at the top of the connecting slide rod 540. A return spring is fixed between the end of the connecting slide rod 540 away from the connecting rotating rod 530 and the inner wall of the collecting plate 510. A protective cover 560 slides inside the collecting box 520. A lower slide seat 570 that rotates and connects to the top of the connecting push rod 550 is fixed to the outer wall of the protective cover 560. An upper slide seat 580 that slides inside the collecting box 520 is fixed to the outer wall of the protective cover 560 and above the lower slide seat 570. A guide groove 590 that matches the upper slide seat 580 is opened inside the collecting box 520, and the lower slide seat 570 slides inside the guide groove 590.

[0063] When extracting lithium from materials requiring chromatography, a soft silica gel mixture is introduced into the chromatography tube body 210, followed by the material to be chromatographically analyzed. This increases the overall weight of the chromatography tube body 210, causing it to slide within the sliding sleeve 230 and slide the tube connecting rod 310. At this point, the side fixing rod 410 separates from the lever 422. The transmission rotating rod 420 then resets under the action of the transmission torsion spring 421, driving the transmission slider 430 to slide against the outer wall of the transmission slide plate 440. This, in turn, causes the airbag pusher plate 450 to contact the outer wall of the airbag body 460, allowing the airbag body 460 to... The negative pressure is generated, which pushes the telescopic piston rod 480 sliding inside the piston cylinder 470 to slide. Then, under the connection of the transmission cylinder 490, multiple sets of connecting rotating rods 530 can be pushed to rotate around the contact position with multiple sets of connecting sliding rods 540, which can push the connecting sliding rods 540 to slide inside the collection plate 510. The connecting push rod 550 can be pulled to rotate around the contact position with the lower sliding seat 570, which can pull the upper sliding seat 580 and the lower sliding seat 570 fixed to the outer wall of the protective cover 560 to slide inside the guide groove 590.

A straight groove rotating disk 660 is fixed to the inner wall of the central fixed plate 130 and below the arc-groove rotating disk 650. An in-groove slide rod 670 extending into the straight groove rotating disk 660 is opened inside the arc-groove rotating disk 650. The top of the 50 has multiple sets of arc-shaped grooves 651 that match the sliding rod 670 inside the groove. The top of the straight groove turntable 660 has a straight sliding groove 661 that matches the sliding rod 670 inside the groove. The outer wall of the sliding rod 670 inside the groove is fixed with a sliding rod side rod 680 extending to the outside of the straight groove turntable 660. The other end of the sliding rod side rod 680 is fixed with an outer push plate 690. The outer side of the column chromatography equipment assembly 100 is provided with a discharge assembly 700 extending into the interior of the chromatography assembly 200. The discharge assembly 700 includes multiple sets of outer guide rings 710 fixed to the outer wall of the central fixed plate 130. The discharge hopper 720 slides inside the outer guide rings 710 below the chromatography tube body 210. The outer wall of the outer push plate 690 is fixed with an extension rod 721 extending into the interior of the discharge hopper 721. 1. A first trapezoidal block 722 is fixed at the other end and slides inside the discharge hopper 720. A second trapezoidal block 730 is fixed inside the discharge hopper 720 and contacts the first trapezoidal block 722. A sealing sleeve 740 extends into the top of the discharge hopper 720. An inner guide groove 731 matching the second trapezoidal block 730 is opened inside the outer guide ring 710, and the inner guide groove 731 is "L" shaped. A pair of first magnetic blocks that attract each other are arranged between the second trapezoidal block 730 and the first trapezoidal block 722. A rack 760 extending to the outside slides inside the chromatography tube body 210. A magnetic baffle 750 that contacts the sealing sleeve 740 is fixed on the side of the rack 760 near the outer wall of the chromatography tube body 210. The magnetic baffle 750 and the sealing sleeve 740 are connected. A pair of mutually attracting second magnetic blocks are arranged between the sealing sleeve 740 and the chromatography tube body 210, and a pair of mutually attracting third magnetic blocks are arranged between the sealing sleeve 740 and the chromatography tube body 210. Inside the chromatography tube body 210, there is a rotating gear 770 that meshes with the rack 760. At the top of the gear 770, there is a wound conical disk 780 that rotates on the inner wall of the chromatography tube body 210. A conical spiral wire 790 is wound on the outer wall of the wound conical disk 780. An inner cone block 791 is fixed at the bottom of the conical spiral wire 790, and an outer cone block 792 is fixed at the other end of the inner cone block 791. The chromatography tube body 210 has a movable slot that matches the inner cone block 791, and the movable slot extends to the inner wall of the chromatography tube body 210. The conical spiral wire 790 is made of iron and has a certain degree of elasticity.

[0065] When chromatography is complete, the drive motor 620 can be started to rotate the rotating shaft 610, which in turn rotates the sector plate 630. Then, connected to the rotating cylinder 640, the arc groove turntable 650 rotates. At this time, the sliding rod 670 slides inside the arc groove 651. Simultaneously, under the constraint of the straight sliding groove 661 at the end of the straight groove turntable 660, the sliding rod 670 slides linearly inside the straight groove turntable 660. Connected to the sliding rod side rod 680, multiple sets of outward push plates 690 gradually move away from each other, causing the first trapezoidal block 722 fixed at the other end of the extension rod 721 to slide. Under magnetic action, the second trapezoidal block 730 fixed to the discharge hopper 720 can be pulled vertically. When the second trapezoidal block 722... When the 30 cannot slide vertically continuously, it can slide horizontally as the first trapezoidal block 722 continues to push it, allowing the sealing sleeve 740 to separate from the outer shell of the chromatography tube body 210. This facilitates cleaning of the inner wall of the chromatography tube body 210. At the same time, the magnetic baffle 750 can be pulled to slide, causing the rack 760 to slide, which in turn drives the gear 770 meshing with the rack 760 to rotate. This causes the winding cone disk 780 to rotate, allowing the conical spiral wire 790 wound on the outer wall of the winding cone disk 780 to separate from it and slide inside the chromatography tube body 210. This allows the outer cone block 792 to be inserted into the soft silicone, pushing the soft silicone out to the bottom of the chromatography tube body 210, facilitating the removal of the soft silicone.

[0066] When using it, step one: when extracting lithium from the material that needs to be chromatographically analyzed, the soft silica gel mixture can be put into the chromatography tube body 210, and then the material that needs to be chromatographically analyzed can be put into the chromatography tube body 210.

[0067] Step 2: At this time, the overall weight inside the chromatography tube body 210 increases, and the chromatography tube body 210 slides inside the sliding sleeve 230, causing the tube connecting rod 310 to slide. At this time, with the cooperation of the transmission component 400 and the collection component 500, the protective cover 560 sliding on the top of the multiple collection boxes 520 flips and slides into the collection box 520, so that the collection box 520 is in the open state.

[0068] Step 3: At this point, elution solvent can be injected into one of the chromatography tube bodies 210. The overall weight of the chromatography tube body 210 gradually decreases from high to low. The material precipitated inside the tube enters the collection box 520 through the discharge hopper 720. When the weight inside the chromatography tube body 210 no longer changes, with the cooperation of the gravity transmission component 300, the quantitative disk 390 can be driven to rotate regularly at a specified angle. Then, with the connection of the collection plate 510, multiple sets of collection boxes 520 can be driven to rotate regularly. At this time, elution solvent can be injected into the remaining multiple sets of chromatography tube bodies 210 in sequence, which can achieve the effect of centralized collection of different chromatographic materials.

[0069] Step 4: When the chromatography is completed, the drive motor 620 can be started. With the cooperation of the separation component 600, the multiple sets of push plates 690 can be gradually moved away from each other. With the cooperation of the discharge component 700, the sealing sleeve 740 can be separated from the outer shell of the chromatography tube body 210, which can facilitate the cleaning of the inner wall of the chromatography tube body 210.

[0070] Step 5: At the same time, the magnetic baffle 750 can be pulled to slide. With the cooperation of the rack 760, gear 770 and winding cone 780, the winding cone 780 can be rotated, and the conical spiral wire 790 can slide inside the chromatography tube body 210. The outer cone block 792 can be inserted into the soft silicone and pushed out of the chromatography tube body 210, which can facilitate the removal of the soft silicone.
