A device for rapid purification of lithium carbonate preparation

Abstract

This invention discloses a rapid purification device for lithium carbonate preparation, relating to the technical field of lithium carbonate preparation. It includes an installation platform, with a feeding unit mounted on one side of the top surface of the platform via a bracket, and a sintering unit mounted on the other side of the top surface of the platform via a bracket. The sintering unit is used for raw material mixing and sintering. The feeding unit includes a conical hopper and a hopper support. After the raw materials in the feeding unit are added, the installation platform resets, and the sintering unit can continue to perform high-temperature mixing and sintering of the raw materials inside. At this time, there are raw materials inside both sintering cylinders. This allows the sintering unit to retain a certain amount of high-temperature raw materials during the discharge process, preventing a sharp drop in the internal temperature of the hopper due to the discharge of raw materials. This, in turn, improves the lithium carbonate preparation efficiency by shortening the heating process inside the sintering cylinders.

Description

Technical Field

[0001] This invention relates to the technical field of lithium carbonate preparation, and more specifically, to a rapid purification apparatus for lithium carbonate preparation. Background Technology

[0002] Lithium carbonate is an inorganic compound with the chemical formula Li₂CO₃ and a molecular weight of 73.89. It is a colorless monoclinic crystal, slightly soluble in water and dilute acids, but insoluble in ethanol and acetone. Its thermal stability is lower than that of carbonates of other elements in the same group of the periodic table. It does not deliquesce in air and can be obtained by adding sodium carbonate to lithium sulfate or lithium oxide solutions. Passing carbon dioxide into its aqueous solution converts it to an acidic salt, and boiling causes hydrolysis. It is used as a raw material in ceramics, glass, ferrites, and for silver paste coating of components. The production process of lithium carbonate can be divided into extraction from salt lake brine and extraction from ores.

[0003] The main process of lithium carbonate extraction from ore using the spodumene and sulfate mixed sintering method involves adding spodumene concentrate and K2SO4 (or CaSO4 or a mixture of both) into a mixing chamber and sintering them at 250 to 300 degrees Celsius. After a series of physical and chemical reactions, the metal elements in the added sulfate replace lithium in the ore to form soluble sulfates, while the main impurities are converted into compounds that are insoluble in water. The sintered clinker is then leached and separated, and the lithium ions enter the solution. After purification, concentration, and precipitation, lithium carbonate is obtained.

[0004] In the sintering process of lithium spodumene ore and K2SO4, the mixing chamber needs to be kept at a high temperature. Normally, the mixing chamber, where raw materials are sintered, is mostly in a closed state. However, there is an upper limit to the amount of raw materials that can be mixed and sintered at one time. When the sintered raw materials are removed from the chamber, they carry away a large amount of heat, causing a sharp drop in the chamber temperature. This necessitates reheating the chamber to the sintering range before material replacement. This reheating process increases energy consumption and time, reducing the production efficiency of the sintered product and consequently decreasing the efficiency of lithium carbonate preparation and purification. Based on these problems, we provide a rapid purification device for lithium carbonate preparation. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides a rapid purification apparatus for the preparation of lithium carbonate.

[0006] The present invention provides a rapid purification apparatus for lithium carbonate preparation, which adopts the following technical solution:

[0007] A rapid purification apparatus for lithium carbonate preparation includes an installation platform. A feeding unit is mounted on one side of the top surface of the installation platform via a bracket, and a sintering unit is mounted on the other side of the top surface of the installation platform via a bracket. The sintering unit is used for mixing and sintering raw materials. The feeding unit includes a conical hopper and a hopper support. The bottom of the hopper support is fixedly connected to the top surface of the installation platform. A first lifting ring is fixedly connected to the upper outer wall of the conical hopper. The outer wall of the first lifting ring engages with the inner wall of the upper circular groove of the hopper support. A transfer assembly is provided between the feeding unit and the sintering unit. The transfer assembly includes a three-way pipe, one end of which is connected to the bottom of the conical hopper via a rotary joint.

[0008] Preferably, the sintering unit includes a central baffle, the bottom of which is fixedly connected to the top surface of the mounting platform. A circular baffle is fixedly connected above the central baffle. Connecting rings are fixedly connected to both sides of the circular baffle. Sintering cylinders are snapped onto the outer walls of both connecting rings. A sealing plate is fixedly connected to the inner wall of one of the sintering cylinders near one edge. The other port of the tee pipe is connected to the center of one side of the sealing plate via a rotary joint. An auger is provided between the two ports of the tee pipe, with the center of the auger positioned... Below the projection of the other connector of the tee pipe, both ends of the auger are fixed to the cylinder wall support by bearings. The two cylinder wall supports are fixed to the inner wall of the tee pipe. The end of the auger away from the sintering unit is provided with a multi-faceted groove. A multi-faceted prism is engaged between the inner walls of the multi-faceted groove. One end of the multi-faceted prism extends through to the outside of the tee pipe. A prism frame is engaged with the outer wall of the multi-faceted prism near the outer wall of the first bevel gear. The outer periphery of the prism frame is engaged with the inner wall of the circular rail of one end connector of the tee pipe. The first bevel gear is fixed to one end of the multi-faceted prism.

[0009] Preferably, a first annular bevel gear is fixedly connected to the outer wall of one end of one of the sintering cylinders, and a first transmission rod is mounted on the lower side of one side of the hopper support via a bracket. Both ends of the first transmission rod are fixedly connected to second bevel gears, one of the second bevel gears meshing with the first annular bevel gear, and a transmission component is provided between the other second bevel gear and the first bevel gear.

[0010] Preferably, the transmission assembly includes a second transmission rod and a third transmission rod. The outer walls of both the second and third transmission rods are fitted with V-shaped positioning frames via brackets. Both V-shaped positioning frames are fixedly connected to the outer wall of the support column of the hopper support. One end of the second transmission rod is fixedly connected to a third bevel gear, which meshes with another second bevel gear. The other end face of the second transmission rod is fixedly connected to a first linkage tooth. One end of the third transmission rod is fixedly connected to a fourth bevel gear, which meshes with the first bevel gear. A linkage sleeve is slidably fitted onto the lower outer wall of the third transmission rod via a track. The bottom surface of the linkage sleeve is fixedly connected to a second linkage tooth, which can mesh with the first linkage tooth. A first electric telescopic rod is installed inside the lower part of the linkage sleeve, and the telescopic end of the first electric telescopic rod is fixedly connected to one end of the third transmission rod.

[0011] Preferably, a second annular bevel gear is fixedly connected to the outer wall of the conical hopper, and the second annular bevel gear meshes with the first annular bevel gear. Gear rings are fixedly connected to the outer walls of the two sintered cylinders near their ends. A gear frame is fixedly connected to one side of the centrally located baffle on the top surface of the mounting platform. Two coaxial gears are installed inside the gear frame via shafts. The two coaxial gears mesh with two gear rings respectively. A motor is installed on one side of the gear frame, and the output shaft of the motor is fixedly connected to the axis of the coaxial gear.

[0012] Preferably, a first hanging baffle is suspended above the interior of the central baffle, the outer periphery of the first hanging baffle contacts the inner wall of the connecting ring, a sealing sleeve is fixed to the top surface of the mounting platform by a bracket, the inner wall of the sealing sleeve is rotated to seal the outer wall of one of the sintering cylinders away from the sintering unit, and a second hanging baffle is suspended above one side of the sealing sleeve.

[0013] Preferably, a wireless pressure sensor is installed on the lower inner wall of the conical hopper, and a controller is installed between the pillars of the hopper support via a bracket. The controller is signal-connected to the wireless pressure sensor, and the controller is electrically connected to the first electric telescopic rod via a wire passing through the second transmission rod and the linkage sleeve.

[0014] Preferably, an adjustable base is mounted on one side of the installation platform via a bracket, and a linkage rail is fixedly connected to the bottom surface of the other side of the installation platform. A second electric telescopic rod is mounted on one side of the top surface of the adjustable base via a shaft. A linkage slider is mounted on the telescopic end of the second electric telescopic rod via a shaft. The outer wall of the linkage slider is engaged with the inner wall of the linkage rail.

[0015] Preferably, auxiliary supports are fixed to the top surface of the mounting platform near both ends, and the inner walls of the two auxiliary supports are respectively fitted to the outer walls of the convex rings of the two sintered cylinders.

[0016] In summary, the present invention has the following beneficial technical effects:

[0017] 1. The first hanging baffle, installed between two sintering cylinders, is mounted on the inner wall of the annular baffle, creating a deflection resistance at one end. This causes the second hanging baffle and the sealing sleeve to deflect first when the installation platform is tilted. At this time, the sintering cylinder on this side discharges material. Meanwhile, the sintering cylinder on the other side, under the operation of the feeding unit and with the material resistance of the first hanging baffle, accumulates raw material inside. The deflection force on the first hanging baffle continuously increases. When it accumulates to a certain level, the first hanging baffle... When the material is deflected relative to the circular baffle, it is quickly discharged into another sintering cylinder under the action of gravity, thus facilitating the replacement of raw materials inside the sintering cylinder. After the material in the feeding unit is added, the mounting platform is reset, and the sintering unit can continue to perform high-temperature mixing and sintering of the material inside. At this time, there is raw material inside both sintering cylinders. This allows the sintering unit to reserve a certain amount of high-temperature raw material during the material discharge process, preventing the problem of a sharp drop in the internal temperature of the hopper due to the discharge of raw material. In turn, the process of heating the inside of the sintering cylinder is shortened, thereby improving the production efficiency of lithium carbonate.

[0018] 2. The linkage sleeve is installed between the two second transmission rods, and the connection or disconnection of the two second transmission rods can be adjusted by controlling the lifting and lowering of the linkage sleeve. The meshing of the fourth bevel gear and the first bevel gear on the prism frame allows the rotation of the auger to be controlled by the rotation of the fourth bevel gear. The linkage sleeve adjusts the linkage between the two second transmission rods so that the rotation state of the auger can be controlled by changing the connection state of the two second transmission rods as needed.

[0019] 3. The sintering cylinder is connected by the first and second ring bevel gears, which allows the sintering cylinder to drive the conical hopper to rotate during the rotation process. This ensures that the raw materials in the sintering cylinder can maintain their movement during the rotation and sintering process, preventing the raw materials from being left in the sintering cylinder for too long, which could lead to difficulties in material discharge.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figures 1 to 11 The present invention will be described in further detail below.

[0033] It should be noted that the accompanying drawings are schematic and not to scale. For clarity and convenience, the relative dimensions and proportions of the parts shown are exaggerated or reduced in size; all dimensions are merely illustrative and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.

[0034] This invention discloses a rapid purification apparatus for the preparation of lithium carbonate. (Refer to...) Figures 1 to 11 A rapid purification device for lithium carbonate preparation includes an installation platform 1. A feeding unit 2 is mounted on one side of the top surface of the installation platform 1 via a bracket, and a sintering unit 3 is mounted on the other side of the top surface of the installation platform 1 via a bracket. The sintering unit 3 is used for raw material mixing and sintering. The feeding unit 2 includes a conical hopper 21 and a hopper support 22. The bottom of the hopper support 22 is fixedly connected to the top surface of the installation platform 1. A first lifting ring 211 is fixedly connected to the upper outer wall of the conical hopper 21. The outer wall of the first lifting ring 211 engages with the inner wall of the upper circular groove of the hopper support 22. A transfer assembly 4 is provided between the feeding unit 2 and the sintering unit 3. The transfer assembly 4 includes a three-way pipe 41. One end of the three-way pipe 41 is connected to the bottom of the conical hopper 21 via a rotary joint.

[0035] Specifically, the feeding unit 2 and the sintering unit 3 are respectively installed above the installation platform 1. The raw material to be added is placed inside the conical hopper 21. The transfer component 4 is installed between the feeding unit 2 and the sintering unit 3 as a transfer structure. It can play a role in conducting the raw material inside the conical hopper 21. When the raw material inside the conical hopper 21 accumulates to a certain weight, the transfer component 4 operates, and the raw material is transferred to the sintering unit 3 through the three-way pipe 41. The raw material is sintered under the high temperature rotation of the sintering unit 3.

[0036] The conical hopper 21 and the hopper support 22 are connected by a circular groove to the first lifting ring 211, which allows the raw material placed inside the conical hopper 21 to be in constant motion by rotating the conical hopper 21. This prevents the raw material from being left to stand still for a long time inside the conical hopper 21, which would cause difficulties in unloading and increases the rationality of the device structure.

[0037] Reference Figures 2 to 7The sintering unit 3 includes a central baffle 11, the bottom of which is fixedly connected to the top surface of the mounting platform 1. A circular baffle 111 is fixedly connected above the central baffle 11. Connecting circular rings 112 are fixedly connected to both sides of the circular baffle 111. Sintering cylinders 31 are snapped onto the outer walls of both connecting circular rings 112. A sealing circular plate 311 is fixedly connected to the inner wall of one of the sintering cylinders 31 near one edge. The other port of the three-way pipe 41 is connected to the center of one side of the sealing circular plate 311 through a rotary joint. An auger 42 is provided between the two ports of the three-way pipe 41, with the center of the auger 42 located at the three-way pipe 41. Below the projection of the other connector, both ends of the auger 42 are fixed to the cylinder wall support 421 by bearings. The two cylinder wall supports 421 are fixed to the inner wall of the three-way pipe 41. The end of the auger 42 away from the sintering unit 3 has a polygonal groove 422. A polygonal prism 43 is engaged between the inner walls of the polygonal groove 422. One end of the polygonal prism 43 extends through to the outside of the three-way pipe 41. A prism frame 431 is engaged with the outer wall of the polygonal prism 43 near the outer wall of the first bevel gear 432. The outer periphery of the prism frame 431 is engaged with the inner wall of the circular rail of one end of the three-way pipe 41. The first bevel gear 432 is fixed to one end of the polygonal prism 43.

[0038] Specifically, the central baffle 11 on the installation platform 1 is installed with the connecting ring 112 via the circular baffle 111. The linkage between the circular rails and the sintering cylinder 31 between the connecting ring 112 and the circular rails ensures that the two sintering cylinders 31 are coaxial. This allows the raw materials entering the sintering unit 3 to flow unimpeded within the two sintering cylinders 31, ensuring that the connecting ring 112, which forms an integral structure with the installation platform 1, does not impede the rotation of the sintering cylinder 31. One end of the three-way pipe 41 is connected to the sealing plate 311 via a rotary joint, enabling the conveying connection between the three-way pipe 41 and the sintering cylinder 31. The connection method allows the three-way pipe 41 and the sintering cylinder 31 to be connected in a state of mutual non-interference. The auger 42 installed inside the three-way pipe 41 through the cylinder wall support 421 can input the raw material inside the three-way pipe 41 into the sintering cylinder 31 through its own rotation. Due to the intermittent sealing structure of the auger 42, the raw material inside the three-way pipe 41 is also in a static state when the auger 42 is not rotating. At this time, no material is added to the sintering cylinder 31. The multi-faceted groove 422 opened at one end of the auger 42 can be engaged with the multi-faceted prism 43, so that the rotation of the auger 42 can be controlled by rotating the multi-faceted prism 43 to realize the conveying of raw material in the sintering cylinder 31.

[0039] Reference Figures 2 to 8One of the sintering cylinders 31 has a first annular bevel gear 312 fixedly connected to the outer wall of one end. A first transmission rod 44 is mounted on the lower side of one side of the hopper support 22 via a bracket. Both ends of the first transmission rod 44 are fixedly connected to second bevel gears 441. One of the second bevel gears 441 meshes with the first annular bevel gear 312, and a transmission assembly 45 is provided between the other second bevel gear 441 and the first bevel gear 432.

[0040] Specifically, the first transmission rod 44 is installed below the hopper support 22 under the action of the two, and the transmission connection between the structures is realized through the three-way pipes 41 installed at both ends. The sintering cylinder 31 meshes with the second ring bevel gear 212 through the first ring bevel gear 312, so that the sintering cylinder 31 can drive the conical hopper 21 to rotate during the rotation process. In this way, the raw material in the sintering cylinder 31 can also maintain the state of movement through the rotation of the sintering cylinder 31 during the rotation sintering process, so as to prevent the raw material from being stationary in the sintering cylinder 31 for too long, which would lead to the difficulty of material discharge. The linkage between the other second bevel gear 441 and the first transmission rod 44 is realized through the transmission component 45.

[0041] Reference Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 8 The transmission assembly 45 includes a second transmission rod 451 and a third transmission rod 456. The outer walls of both the second and third transmission rods 451 and 456 are fitted with V-shaped positioning frames 452 via brackets. Both V-shaped positioning frames 452 are fixedly connected to the outer wall of the support column of the hopper support 22. One end of the second transmission rod 451 is fixedly connected to a third bevel gear 453, which meshes with another second bevel gear 441. The other end face of the second transmission rod 451 is fixedly connected to a first linkage tooth 454. A fourth bevel gear 455 is fixedly connected to one end of the third transmission rod 456. The fourth bevel gear 455 meshes with the first bevel gear 432. A linkage sleeve 46 is slidably sleeved on the lower outer wall of the third transmission rod 456 via a track. A second linkage tooth 461 is fixedly connected to the bottom surface of the linkage sleeve 46. The second linkage tooth 461 can mesh with the first linkage tooth 454. A first electric telescopic rod 47 is installed inside the lower part of the linkage sleeve 46. The telescopic end of the first electric telescopic rod 47 is fixedly connected to one end of the third transmission rod 456.

[0042] Specifically, in the rotating state, the first transmission rod 44 can drive the third bevel gear 453, which meshes with it, to rotate through the second bevel gear 441, thereby driving the second transmission rod 451 to rotate. The first linkage tooth 454 is a structure installed at one end of the second transmission rod 451 and linked with the third transmission rod 456. The linkage sleeve 46 is installed between the second transmission rod 451 and the third transmission rod 456, and the connection or disconnection of the second transmission rod 451 and the third transmission rod 456 can be adjusted by controlling the lifting and lowering of the linkage sleeve 46. The meshing of the fourth bevel gear 455 and the first bevel gear 432 on the prism frame 431 allows the rotation of the auger 42 to be controlled by the rotation of the fourth bevel gear 455. The linkage sleeve 46 adjusts the linkage between the second transmission rod 451 and the third transmission rod 456 so that the rotation state of the auger 42 can be controlled by changing the connection state of the second transmission rod 451 and the third transmission rod 456 as needed.

[0043] When the fourth bevel gear 455 needs to rotate, the first electric telescopic rod 47 extends. At this time, the linkage sleeve 46 moves down to the state where the second linkage tooth 461 meshes with the first linkage tooth 454. At this time, the rotation of the fourth bevel gear 455 can drive the auger 42 linked with it to rotate, thereby realizing the feeding of the three-way pipe 41 to the sintering cylinder 31.

[0044] When it is necessary to stop feeding, the first electric telescopic rod 47 retracts. At this time, the linkage sleeve 46 moves up to the state where the second linkage tooth 461 is disengaged from the first linkage tooth 454. Similarly, at this time, the auger 42 stops rotating, thereby stopping the feeding of the three-way pipe 41 to the sintering cylinder 31.

[0045] Furthermore, the second transmission rod 451 and the third transmission rod 456 are fixed to the side of the hopper support 22 through the cooperation of the V-shaped positioning frame 452, so that the two hopper supports 22 can only rotate, increasing the rationality of the device structure.

[0046] Reference Figure 4 and Figure 5 The outer wall of the conical hopper 21 is fixedly connected to a second annular bevel gear 212, which meshes with the first annular bevel gear 312. Gear rings 313 are fixedly connected to the outer walls of the two sintered cylinders near their ends. A gear frame 32 is fixedly connected to one side of the centrally located baffle 11 on the top surface of the mounting platform 1. Two coaxial gears 321 are installed inside the gear frame 32 via shafts. The two coaxial gears 321 mesh with the two gear rings 313 respectively. A motor 322 is installed on one side of the gear frame 32, and the output shaft of the motor 322 is fixedly connected to the axis of the coaxial gear 321.

[0047] Specifically, after the sintering cylinder 31 and the connecting ring 112 are linked and installed, they mesh with the coaxial gear 321 through the gear ring 313 on the ring 112. The rotation of the coaxial gear 321 can drive the two sintering cylinders 31 to rotate synchronously. The motor 322 is installed on one side of the gear frame 32 and provides output force for its rotation through the connection between its output shaft and the coaxial gear 321. Thus, after the raw material is introduced into the sintering cylinder 31, while ensuring the high temperature inside, the raw material can be kept in motion inside the sintering cylinder 31 by rotating the sintering cylinder 31, ensuring that the raw material is heated evenly inside the sintering cylinder 31.

[0048] Reference Figure 4 and Figure 5 A first hanging baffle 12 is suspended above the interior of the central baffle 11. The outer periphery of the first hanging baffle 12 contacts the inner wall of the connecting ring 112. A sealing sleeve 13 is fixed to the top surface of the mounting platform 1 by a bracket. The inner wall of the sealing sleeve 13 rotates and seals the outer wall of one of the sintering cylinders 31 away from the sintering unit 3. A second fishing baffle 14 is suspended above one side of the sealing sleeve 13.

[0049] Specifically, the central baffle 11 is hoisted to the first vertical baffle 12 via a shaft. The central baffle 11 and the mounting platform 1 are relatively fixed, which means that when the mounting platform 1 is in a horizontal state under the action of gravity, the first vertical baffle 12 is perpendicular to the horizontal plane. At this time, the first vertical baffle 12 isolates the two sintering cylinders 31, preventing the raw materials inside the two sintering cylinders 31 from interacting. The sealing sleeve 13 is also relatively installed on the mounting platform 1. Through the rotational seal between the sealing sleeve 13 and one side of the sintering cylinder 31, the outlet of the sintering cylinder 31 on that side can be blocked by sealing the opening of the sealing sleeve 13. The second vertical baffle 14 is installed in the same way as the first vertical baffle 12, so that it can act as a sealing structure to block the discharge port of the sintering cylinder 31.

[0050] Furthermore, when the sintering cylinder 31 needs to be unloaded, by adjusting the overall tilt angle of the installation platform 1, under the action of gravity, both the first hanging baffle 12 and the second hanging baffle 14 have a tendency to move perpendicular to the horizontal plane, thereby opening the sintering cylinder 31 and discharging material from it. The first hanging baffle 12, installed between the two sintering cylinders 31, is installed between the inner walls of the annular baffle 111, resulting in a deflection resistance at one end between it and the inner wall of the annular baffle 111. This allows the second hanging baffle 14 to deflect first between itself and the sealing sleeve 13 when the installation platform 1 is tilted as a whole. At this time, the sintering cylinder 31 on this side performs the discharging operation, while the sintering cylinder 31 on the other side, under the operation of the feeding unit 2 and in conjunction with the material resistance of the first hanging baffle 12, can sinter on this side. A certain amount of raw material is accumulated inside the sintering cylinder 31. At this time, the deflection force on the first hanging baffle 12 continuously increases. When it accumulates to a certain extent, the first hanging baffle 12 and the circular baffle 111 deflect relative to each other. At this time, the material is quickly discharged into the other sintering cylinder 31 under the action of gravity, so as to realize the replacement of the raw material inside the sintering cylinder 31. After the raw material in the feeding unit 2 is added, the mounting platform 1 is reset, and the sintering unit 3 can continue to perform high-temperature mixing and sintering of the raw material inside. At this time, there is raw material inside both sintering cylinders 31. Thus, during the discharge process of the sintering unit 3, a certain amount of raw material containing high temperature can be reserved to prevent the problem of a sharp drop in the internal temperature of the hopper due to the discharge of raw material. In this way, the heating process inside the sintering cylinder 31 is shortened, and the preparation efficiency of lithium carbonate is improved.

[0051] Reference Figure 1 , Figure 8 and Figure 9 A wireless pressure sensor 5 is installed on the lower inner wall of the conical hopper 21. A controller 51 is installed between the pillars of the hopper support 22 via a bracket. The controller 51 is signal-connected to the wireless pressure sensor 5. The controller 51 is electrically connected to the first electric telescopic rod 47 via a wire passing through the second transmission rod 451 and the linkage sleeve 46.

[0052] Specifically, the installation of the wireless pressure sensor 5 can measure the amount of raw material entering the conical hopper 21. When the amount of raw material in the conical hopper 21 accumulates to a certain amount, the wireless pressure sensor 5, which is connected to it by an electrical signal, is activated and controls the first electric telescopic rod 47 to expand, so that the second transmission rod 451 and the third transmission rod 456 are connected to each other and drive the auger 42 to rotate under the transmission action to realize feeding. When a certain amount of material in the conical hopper 21 is discharged into the sintering cylinder 31, the auger 42 stops rotating and stops feeding into the sintering cylinder 31.

[0053] Reference Figure 8 , Figure 9 , Figure 10 and Figure 11 An adjustable base 6 is mounted on one side of the installation platform 1 via a bracket, and a linkage rail 15 is fixedly connected to the bottom surface of the other side of the installation platform 1. A second electric telescopic rod 61 is mounted on one side of the top surface of the adjustable base 6 via a shaft. A linkage slider is mounted on the telescopic end of the second electric telescopic rod 61 via a shaft. The outer wall of the linkage slider is engaged with the inner wall of the linkage rail 15.

[0054] Specifically, the adjusting base 6 is installed below the mounting platform 1. The second electric telescopic rod 61 and the linkage rail 15 are engaged to allow the second electric telescopic rod 61 to contract or expand, controlling the overall upward tilting angle or resetting of the mounting platform 1. The telescopic control device of the second electric telescopic rod 61 is also electrically connected to the controller 51. This allows the second electric telescopic rod 61 to expand when the feeding unit 2 is running, causing the mounting platform 1 to tilt upward, and the second electric telescopic rod 61 to contract when the feeding unit 2 stops running, causing the mounting platform 1 to reset. This achieves coordination with the unloading operation of the sintering unit 3.

[0055] Reference Figure 1 and Figure 5 The top surface of the mounting platform 1 is fixed with auxiliary brackets 16 near the two ends. The inner walls of the two auxiliary brackets 16 are respectively fitted with the outer walls of the convex rings of the two sintered cylinders 31.

[0056] Specifically, through the cooperation between the auxiliary support 16 and the convex rings on both sides of the sintering cylinder 31, the auxiliary support 16 does not hinder the rotation of the sintering cylinder 31 while providing support, thus increasing the rationality of the device structure.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0058] The implementation principle of a rapid purification device for lithium carbonate preparation according to an embodiment of the present invention is as follows: the raw material to be added is placed inside a conical hopper 21. When the raw material inside the conical hopper 21 accumulates to a certain weight, the transfer component 4 operates, and the raw material is transferred to the sintering unit 3 through a three-way pipe 41. The raw material is then sintered under the high temperature and rotation of the sintering unit 3. The conical hopper 21 and the hopper support 22 are connected by a circular groove and a first lifting ring 211, so that the raw material placed inside the conical hopper 21 can be kept in motion by rotating the conical hopper 21. The central baffle 11 on the mounting platform 1 is installed with a circular baffle 111 to the connecting ring 112. The circular track and the circular ring between the connecting ring 112 and the sintering cylinder 31 are linked. This arrangement allows the two sintering cylinders 31 to be coaxial. One end of the three-way pipe 41 is connected to the sealing plate 311 via a rotary joint, enabling the conveying connection between the three-way pipe 41 and the sintering cylinder 31. The auger 42, installed inside the three-way pipe 41 via the cylinder wall support 421, can input the raw material inside the three-way pipe 41 into the sintering cylinder 31 through its own rotation. Due to the intermittent sealing structure of the auger 42, the raw material inside the three-way pipe 41 is also stationary when the auger 42 is not rotating, and no material is added to the sintering cylinder 31 at this time. The multi-faceted groove 422 at one end of the auger 42 can engage with the multi-faceted prism 43, thus allowing the rotation of the auger 42 to be controlled by rotating the multi-faceted prism 43. The first transmission rod 44 is positioned between these points. Under the action of the material, it is installed below the hopper support 22, and the transmission connection between some structures is realized through the three-way pipes 41 installed at both ends. The sintering cylinder 31 meshes with the second ring bevel gear 212 through the first ring bevel gear 312, so that the sintering cylinder 31 can drive the conical hopper 21 to rotate during the rotation process. In this way, the material in the sintering cylinder 31 can also maintain the motion state through the rotation of the sintering cylinder 31 during the rotation sintering process. The linkage between the second bevel gear 441 and the first transmission rod 44 is realized through the transmission component 45. The first transmission rod 44 in the rotating state can drive the third bevel gear 453 meshing with it to rotate through the second bevel gear 441, thereby driving the second transmission rod 451 to rotate. The first linkage tooth 454 is installed at one end of the second transmission rod 451 and is linked to the third transmission rod 451. The linkage sleeve 46 is installed between the second transmission rod 451 and the third transmission rod 456, and the connection or disconnection of the second transmission rod 451 and the third transmission rod 456 can be adjusted by raising and lowering the linkage sleeve 46. The meshing of the fourth bevel gear 455 and the first bevel gear 432 on the prism frame 431 allows the rotation of the auger 42 to be controlled by the rotation of the fourth bevel gear 455. The linkage sleeve 46 adjusts the linkage between the second transmission rod 451 and the third transmission rod 456, so that the rotation state of the auger 42 can be controlled by changing the connection state of the second transmission rod 451 and the third transmission rod 456 as needed.When the fourth bevel gear 455 needs to rotate, the first electric telescopic rod 47 expands. At this time, the linkage sleeve 46 moves down to the state where the second linkage tooth 461 meshes with the first linkage tooth 454. The rotation of the fourth bevel gear 455 then drives the auger 42 linked with it to rotate, thereby enabling the three-way pipe 41 to feed material to the sintering cylinder 31. When it is necessary to stop feeding, the first electric telescopic rod 47 retracts. At this time, the linkage sleeve 46 moves up to the state where the second linkage tooth 461 disengages from the first linkage tooth 454. Similarly, the auger 42 stops rotating, thus stopping the three-way pipe 41 from feeding material to the sintering cylinder 31. The second transmission rod 451 and the third transmission rod 456 are fixed to the side of the hopper support 22 through the cooperation of the V-shaped positioning frame 452. After the sintering cylinder 31 and the connecting ring 112 are installed in linkage, they mesh with the coaxial gear 321 through the gear ring 313 on the ring 31. The rotation of the coaxial gear 321 can drive the two sintering cylinders 31 to rotate synchronously. The motor 322 is installed on one side of the gear frame 32 to provide output force for the rotation of the coaxial gear 321. The central baffle 11 is hoisted by the shaft to the first vertical baffle 12. The central baffle 11 and the installation platform 1 are relatively fixed, so that when the installation platform 1 is in a horizontal state under the action of gravity, the first vertical baffle 12 is in a state perpendicular to the horizontal plane. At this time, the first vertical baffle 12 isolates the two sintering cylinders 31, so that the raw materials in the two sintering cylinders 31 do not interact with each other. The sealing sleeve 13 is also relatively installed on the installation platform. On the 1st, the rotary seal between the sealing sleeve 13 and the sintering cylinder 31 on one side allows the outlet of the sintering cylinder 31 on that side to be blocked by sealing the opening of the sealing sleeve 13. Similarly, the second hanging baffle 14 and the first hanging baffle 12 are installed in the same way, allowing them to act as a sealing structure to block the discharge port of the sintering cylinder 31. When the sintering cylinder 31 needs to be unloaded, by adjusting the overall tilt angle of the installation platform 1, both the first hanging baffle 12 and the second hanging baffle 14 have a tendency to move perpendicular to the horizontal plane under the action of gravity, thereby opening the sintering cylinder 31 and discharging material from it. The first hanging baffle 12, installed between the two sintering cylinders 31, is itself mounted on the annular baffle 1. Between the inner walls of 11, there is a deflection resistance at one end between it and the inner wall of the annular baffle 111. This causes the second fishing baffle 14 and the sealing sleeve 13 to deflect first when the entire installation platform 1 is tilted. At this time, the sintering cylinder 31 on this side performs material discharge. Meanwhile, the sintering cylinder 31 on the other side, under the operation of the feeding unit 2 and with the material blocking effect of the first hanging baffle 12, can accumulate a certain amount of raw material inside the sintering cylinder 31 on this side. At this time, the deflection force on the first hanging baffle 12 continuously increases. When it accumulates to a certain extent, the first hanging baffle 12 and the annular baffle 111 deflect relative to each other. At this time, the material is quickly discharged into the other sintering cylinder 31 under the action of gravity, thus realizing the replacement of raw materials inside the sintering cylinder 31.After the raw materials in the feeding unit 2 are added, the mounting platform 1 is reset, and the sintering unit 3 can continue to perform high-temperature mixing and sintering of the raw materials inside. At this time, there are raw materials inside both sintering cylinders 31. This allows the sintering unit 3 to prevent a sharp drop in the internal temperature of the hopper due to the discharge of raw materials by reserving a certain amount of high-temperature raw materials. The installation of the wireless pressure sensor 5 can measure the amount of raw materials entering the conical hopper 21. When the amount of raw materials in the conical hopper 21 accumulates to a certain amount, the wireless pressure sensor 5, which is connected to its electrical signal, is activated, thereby controlling the first electric telescopic rod 47 to expand and contract. This causes the second transmission rod 451 and the third transmission rod 456 to connect relative to each other, and under the transmission action, drive the auger 42 to rotate, realizing feeding. When the material in the conical hopper 21 is discharged into the sintering cylinder... When a certain amount of material is fed, the auger 42 stops rotating, stopping the feeding of the sintering cylinder 31. The adjusting base 6 is installed below the mounting platform 1. The second electric telescopic rod 61 and the linkage rail 15 engage to control the upward tilting angle or reset of the mounting platform 1. The telescopic control device of the second electric telescopic rod 61 is also electrically connected to the controller 51. This allows the second electric telescopic rod 61 to extend when the feeding unit 2 is running, causing the mounting platform 1 to tilt upward, and the second electric telescopic rod 61 to retract when the feeding unit 2 stops running, causing the mounting platform 1 to reset. This achieves coordination with the unloading operation of the sintering unit 3. Through the interaction between the auxiliary bracket 16 and the convex rings on both sides of the sintering cylinder 31, it does not hinder the rotation of the sintering cylinder 31 while providing support.
