Description

Technical Field

[0001] This invention relates to the field of lithium extraction technology from lithium ceramic stone, specifically to a lithium extraction apparatus and method for lithium extraction from lithium ceramic stone. Background Technology

[0002] In recent years, the development and utilization of lithium has developed rapidly with the large-scale application of new energy. Lithium ore is one of the main sources of lithium products. The development of efficient and clean lithium extraction processes from ore and the comprehensive utilization of resources are inevitable trends in this field. Based on the analysis of the composition and structural characteristics of lithium ore, lithium extraction technologies such as acid method, alkali method, and salt method can be used. To extract lithium from lithium porcelain stone ore, the general process is to first crush the lithium porcelain stone, mix it with composite salt, roast it, leach it with hot water acid, separate the solid and liquid, and purify it to extract lepidolite. Then, lithium is extracted from the lepidolite.

[0003] However, existing lithium extraction methods mainly rely on the filter screen of a filtration device to intercept the filter residue in the mixture when performing the solid-liquid separation step of the lithium ceramic-liquid mixture. However, after prolonged use, the filter residue accumulates thicker and thicker on the filter screen, which slows down the flow rate of the filtrate and affects the purity of the filtrate. As a result, the current step needs to be stopped to remove the filter residue from the filter screen. The inability to remove and collect the filter residue in a timely manner affects the lithium extraction efficiency.

[0004] In addition, when performing the hot water acid leaching step, the lithium ceramic stone fine powder needs to be mixed with dilute sulfuric acid to obtain a sulfate solid-liquid mixture. However, the existing mixing method is to directly pour the fine powder and dilute sulfuric acid together and stir. The mixing efficiency is low, and it is easy for the fine powder to not be fully mixed and contacted with the dilute sulfuric acid, thus affecting the subsequent lithium extraction purity. Summary of the Invention

[0008] Furthermore, the leaching mechanism includes a Y-shaped mixing cylinder. The Y-shaped mixing cylinder is fixedly connected to the front of the mounting frame.

A reciprocating telescopic rod is fixedly connected between the vertical rod and the Y-shaped mixing cylinder.

[0009] Furthermore, a trigger valve is installed at the lower end of the Y-shaped mixing cylinder. A female lever is hinged to the front of the trigger valve via a rotating shaft. A male lever is hinged to the right end of the female lever via an ear block and a torsion spring. A limit plate is fixedly connected to the lower part of the right end face of the female lever.

[0013] A method for extracting lithium from lithium ceramic stone, which is completed using a lithium ceramic stone lithium extraction preparation device, includes the following steps: S1: large pieces of lithium ceramic stone are crushed by a crushing device, and then the crushed lithium ceramic stone is mixed with composite salt.

[0014] S2: Next, the lithium ceramic stone powder in S1 is subjected to acidification leaching treatment by intermittent addition of dilute sulfuric acid through a leaching mechanism;

[0015] S3: Next, the lithium ceramic stone mixture in S2 is separated into solid and liquid components by a filtration mechanism to obtain filtrate and filter residue. Lithium can then be extracted from the obtained lithium-containing filtrate. Beneficial effects

[0016] (1) The sliding block and spiral groove drive the top column to move up and down and rotate, and the lithium ceramic stone liquid mixture is wrapped in the filter bag for twisting and tightening filtration. This can completely squeeze out the filtrate mixed in the filter residue. At the same time, the top column pushes the filter bag into a positive cone shape. In addition, the combination of the paddle plate and the elastic vibrating disc makes the filter bag vibrate, so that the filtered residue can be removed and collected in time, ensuring the normal flow rate of the filtrate and improving the purity of the filtrate.

[0017] (2) By rotating the rolling ball back and forth at the node of the Y-shaped mixing cylinder, the two inclined sections of the through-connecting channel and the Y-shaped mixing cylinder are connected in sequence, so that the lithium ceramic powder and dilute sulfuric acid can be fed into the vertical section in batches and intermittently, so that the fine powder and dilute sulfuric acid can be fully and evenly mixed, greatly improving the mixing effect and improving the subsequent lithium purification accuracy.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1 , Figure 2 and Figure 8This invention provides a technical solution: a lithium extraction device for lithium ceramic stone, comprising a base 1, a box 2 with an upper opening fixedly connected to the upper end face of the base 1, a filter mechanism 3 installed inside the box 2, a mounting frame 4 fixedly connected to the upper end face of the base 1, a leaching mechanism 5 installed at the front of the mounting frame 4 and directly above the filter mechanism 3, the leaching mechanism 5 including a Y-shaped mixing cylinder 51, the Y-shaped mixing cylinder 51 fixedly connected to the front of the mounting frame 4, a ball sleeve 52 with upper and lower openings fixedly connected at the intersection of the inner cavity of the Y-shaped mixing cylinder 51, and a sliding ball 53 rotatably connected inside the ball sleeve 52. 3. A through-connecting channel 54 is provided at the upper part. A rotating column is fixedly connected to the front of the sliding ball 53. The end of the rotating column away from the sliding ball 53 passes through the ball sleeve 52 and the Y-shaped mixing cylinder 51 in sequence. A first push rod 55 is fixedly connected to the outside of the rotating column. A rotating shaft is rotatably connected to the front of the vertical section of the Y-shaped mixing cylinder 51. An agitator 56 is fixedly connected to the end of the rotating shaft located in the inner cavity of the Y-shaped mixing cylinder 51. A second push rod 57 is fixedly connected to the outside of the rotating shaft. A vertical rod 58 is hinged to the ends of the second push rod 57 and the first push rod 55. A reciprocating telescopic rod 59 is fixedly connected between the vertical rod 58 and the Y-shaped mixing cylinder 51.

[0029] The lithium ceramic powder is poured into the left branch pipe of the Y-shaped mixing cylinder 51. Then, dilute sulfuric acid is poured into the right branch pipe of the Y-shaped mixing cylinder 51. Next, the reciprocating telescopic rod 59 is activated, causing the vertical rod 58 to move up and down reciprocally. The vertical rod 58 then drives the first push rod 55 and the second push rod 57 to move reciprocally. The first push rod 55 drives the sliding ball 53 to rotate reciprocally within the ball sleeve 52 via a rotating column. When the sliding ball 53 rotates to the through-connecting channel 54 inside, connecting the inclined and vertical sections of the Y-shaped mixing cylinder 51, the through-connecting channel 54 can be used to connect the inclined section... The lithium ceramic stone fine powder or dilute sulfuric acid is discharged into the vertical section. The lithium ceramic stone fine powder and dilute sulfuric acid are discharged into the vertical section of the Y-shaped mixing cylinder 51 in several intermittent stages. Then, the second push rod 57 reciprocates while driving the agitator 56 to oscillate back and forth through the rotating shaft. The agitator 56 then drives the fine powder and dilute sulfuric acid mixed together in the vertical section of the Y-shaped mixing cylinder 51 to be mixed. By feeding the fine powder and dilute sulfuric acid into the vertical section of the Y-shaped mixing cylinder 51 in stages and intermittently for multiple mixing, the fine powder and dilute sulfuric acid can be mixed evenly and fully.

[0030] Please see Figure 3 , Figure 6 and Figure 7In this embodiment, the filter mechanism 3 includes a mounting ring 31. The mounting ring 31 is fixedly connected to the upper part of the inner cavity of the housing 2 via a fixing rod. The upper surface of the mounting ring 31 gradually slopes towards its edge from the inside out. A semi-annular collection box 20 is symmetrically and detachably connected to the outside of the mounting ring 31. An inverted conical elastic hopper 32 is fixedly connected to the inner cavity of the mounting ring 31. A filter bag 33 is fixedly connected to the lower part of the inverted conical elastic hopper 32. A support plate is fixedly connected to the lower part of the inner cavity of the housing 2. A top column 35 is rotatably connected to the upper surface of the support plate and located directly below the filter bag 33 via a load-bearing telescopic rod 34. The upper part of the top column 35 is fixedly connected to the lower part of the filter bag 33. A vertical plate 37 is fixedly connected to the upper surface of the support plate via an electric telescopic rod 36. A horizontal bar is fixedly connected to the left end face of the vertical plate 37. The lower part of the outer wall of the top column 35 is provided with a spiral groove 38. The rear part of the crossbar is fixedly connected to a slider 39 that is slidably disposed inside the spiral groove 38. Several elastic vibrating discs 310 are fixedly connected at equal intervals along the axial direction of the top column 35. The front cavity wall of the box 2 is fixedly connected to a lever 311 for cooperating with the elastic vibrating discs 310. Several U-shaped elastic sleeves 6 are evenly fixedly connected to the outer wall of the filter bag 33. The upper part of the outer wall of the top column 35 is fixedly connected to a ring 7. Several claw rods 8 corresponding to the elastic sleeves 6 are evenly hinged to the outer wall of the ring 7 through lugs. The upper end of the claw rod 8 is fixedly connected to an umbrella rib rod 9 embedded inside the elastic sleeve 6. A top spring is fixedly connected between the lower part of the claw rod 8 and the outer wall of the ring 7.

[0031] Please see Figure 3 and Figure 5 A sliding rod 15 is fixedly connected to the left cavity wall of the housing 2 via a rod plate. A slip ring 16 is slidably connected to the outside of the sliding rod 15. A connecting plate 17 is fixedly connected to the lower part of the top column 35, and the left part of the connecting plate 17 is fixedly connected to the outside of the slip ring 16. A rod frame is fixedly connected to both the front and rear faces of the connecting plate 17. An inclined rod 18 is hinged to the end of the rod frame via a shaft and a pressing spring. A fitting block 19 is fixedly connected to the upper part of the inclined rod 18 and fits against the outside of the sliding rod 15. A conical elastic guide shield is fixedly connected to the outer wall of the top column 35 and above the elastic vibrating disc 310.

[0032] Please see Figure 4 A trigger valve 10 is installed at the lower end of the Y-shaped mixing cylinder 51. A female lever 11 is hinged to the front of the trigger valve 10 via a rotating shaft. A male lever 12 is hinged to the right end of the female lever 11 via an ear block and a torsion spring. A limit plate 13 is fixedly connected to the lower part of the right end face of the female lever 11. A pressure rod 14 for cooperating with the male lever 12 is fixedly connected to the upper part of the left end face of the vertical plate 37.

[0033] The electric telescopic rod 36 is activated, causing the vertical plate 37 to move up and down repeatedly. The vertical plate 37 then drives the slider 39 to move back and forth via the horizontal bar. During the descent of the vertical rod 58, it drives the pressure rod 14 to move down and then touch the upper part of the sub-lever 12. Then, it drives the female lever 11 to rotate, which in turn drives the trigger valve 10 to open, allowing the mixed lithium ceramic stone liquid mixture in the Y-shaped mixing cylinder 51 to be added into the filter bag 33. At this time, the slider 39 is positioned above the spiral groove 38, and there is a certain frictional resistance between the slider 39 and the spiral groove 38. As the vertical plate 37 descends, the slider 39 pulls the top column 35 down. The top column 35 then moves down via the connecting rod... The connecting plate 17 drives the slip ring 16 to move down. When the slip ring 16 moves down to the bottom of the slide rod 15, the top column 35 stops descending. Then the slider 39 continues to move down and squeezes against the spiral groove 38, driving the top column 35 to descend. The top column 35 then drives the umbrella rib rod 9 to rotate. The umbrella rib rod 9 then drives the filter bag 33 to rotate through the elastic sleeve 6 sleeved on its outside. The filter bag 33 twists and wraps the lithium ceramic stone solid-liquid mixture on its upper part. The filtrate flows into the box 2 through the filter bag 33. The filter residue will be tightened and compressed under the twist of the filter bag 33, squeezing out the filtrate mixed in the filter residue and avoiding the filtrate mixed in the filter residue and causing waste.

[0034] After the filter residue is compressed, the slider 39 moves to the lower end of the spiral groove 38. At this time, the electric telescopic rod 36 starts to push the vertical plate 37 upward. The vertical plate 37 then drives the slider 39 upward through the horizontal bar. The two inclined rods 18 arranged in an inverted V shape, along with the fitting block 19, abut against the outer wall of the slide rod 15, thereby increasing the resistance when the top column 35 rises. The slider 39 first drives the top column 35 to reverse through the compression with the spiral groove 38. The top column 35 then drives the filter bag 33 to rotate in the opposite direction through the umbrella rod 9 and the elastic sleeve 6, so that the filter bag 33, which was in a twisted state, returns to its original position and unfolds. At this time, the slider 39 slides to the upper end of the spiral groove 38. Then, the slider 39 moves upward to lift the top column 35. The top column 35 then pushes the filter bag 33 upward, gradually... The filter bag 33, which is in the shape of a positive cone, is pushed into an inverted cone shape. During the process of the filter bag 33 gradually changing from a positive cone shape to an inverted cone shape, the filter cake inside it is pushed up and flows towards the edge of the mounting ring 31 under the action of the inclined surface of the filter bag 33. At this time, the deflector 311 collides with the elastic vibrating disc 310. The collision between the deflector 311 and the elastic vibrating disc 310 will cause the elastic vibrating disc 310 to vibrate. The elastic vibrating disc 310 then transmits the vibration to the filter bag 33 through the top column 35. The filter bag 33 then uses its own vibration to shake off the filter cake adhering to its surface, which can completely remove the filter cake from the filter bag 33 and avoid the filter cake affecting the next filtration of the filter bag 33.

[0035] After being removed, the filter residue rolls from the filter bag 33 onto the mounting ring 31. Since the upper part of the mounting ring 31 gradually tilts towards its edge from the inside out, the filter residue then falls into the semi-circular collection box 20. Then, the electric telescopic rod 36 starts to drive the vertical plate 37 to descend. The descent of the vertical plate 37 drives the slider 39 to move down, which in turn pulls the top column 35 down. The top column 35 pulls the filter bag 33 down, causing the filter bag 33 to gradually change from an inverted cone shape to a regular cone shape. During the process of the filter bag 33 changing into a regular cone shape, when it just begins to form a regular cone shape, the above initial action will be repeated. The vertical plate 37 drives the pressure rod 14 to contact the upper part of the dial lever. The sub-dial lever 12 then drives the mother dial lever 11 to rotate and open the trigger valve 10, putting the lithium ceramic stone mixture into the filter bag. The above steps are repeated again to perform the next solid-liquid separation operation, and the cycle continues.

[0036] In addition, the present invention also provides a method for extracting lithium from lithium ceramic stone, comprising the following steps: S1: crushing large pieces of lithium ceramic stone using a crushing device, and then mixing the crushed lithium ceramic stone with composite salt.

[0037] S2: Next, the lithium ceramic stone powder in S1 is intermittently acidified and leached by adding dilute sulfuric acid through the leaching mechanism 5. The lithium ceramic stone fine powder is poured into one of the inclined sections of the Y-shaped mixing cylinder 51, and then the dilute sulfuric acid is poured into the other inclined section of the Y-shaped mixing cylinder 51. Then, the vertical rod 58 is driven to reciprocate by the reciprocating telescopic rod 59. The vertical rod 58 is then driven to reciprocate and rotate by the first push rod 55. The reciprocating rotation of the sliding ball 53 makes one side of the through-connecting channel 54 connected to the two inclined sections in the Y-shaped mixing cylinder 51, so that the lithium ceramic stone fine powder and dilute sulfuric acid are intermittently and sequentially fed into the vertical section for mixing.

[0038] S3: Next, the lithium ceramic stone mixture in S2 is separated into solid and liquid by the filtration mechanism 3 to obtain filtrate and filter residue. During the process of the filter bag 33 changing from a conical shape to a positive conical shape, the filter residue and filtrate in the mixture are continuously separated, and the filter residue is removed and collected in time. Then, lithium can be extracted from the obtained lithium-containing filtrate.
