Description

Technical Field

[0001] This utility model relates to the field of mineral extraction equipment technology, and in particular to an equipment for extracting lithium from clay lithium ore. Background Technology

[0002] Lithium clay deposits are sedimentary mineral resources rich in lithium, mainly existing as lithium-bearing clay minerals such as lithium montmorillonite and illite, and are widely distributed in volcanic sedimentary basins or around salt lakes. With the rapid development of the global new energy industry, especially the dramatic increase in demand for lithium resources from electric vehicles and energy storage batteries, traditional salt lake brines and spodumene resources are facing supply pressure. Lithium clay deposits, due to their abundant reserves and relatively mild mining conditions, are gradually becoming a highly promising source of supplementary lithium resources. Therefore, developing efficient, stable, and low-cost technologies and equipment for extracting lithium from lithium clay deposits has become an important research direction in the field of comprehensive lithium resource utilization.

[0003] Existing technology, such as utility model patent CN 222948429 U, discloses a device for efficiently extracting lithium from clay lithium ore. This device includes a support frame and processing components. The processing components consist of a bucket lid, a crushing component, a first motor, a second motor, an auger, a connecting pipe, a mixing tank, a filter plate, a stirring component, and a crushing tank. This device uses the crushing component to initially crush the clay raw material. Material of the appropriate particle size falls to the bottom of the crushing tank through the filter plate. The second motor drives the auger to transport the material to the mixing tank through the connecting pipe. In an acidic solution, the first motor drives the stirring component to carry out a mixing reaction, thereby achieving thorough stirring after crushing and improving reaction efficiency.

[0004] However, the equipment still has significant technical defects in practical applications: the separate design of the crushing tank and the mixing tank results in a dispersed overall structure, which occupies a large space and is not conducive to a compact factory layout; secondly, the materials need to be transported across equipment through augers and connecting pipes, which not only increases the number of mechanical transmission parts, increases the failure rate and maintenance costs, but also makes it easy for blockages or residues to occur during the transportation process, affecting continuous production.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need equipment for extracting lithium from clay lithium ore to solve this problem. This new equipment should significantly improve the integration of crushing and acid leaching processes, reduce material transport links, increase space utilization and operational stability, and better meet the demands of efficient, continuous, and environmentally friendly modern lithium extraction production, providing strong support for the large-scale development and utilization of clay lithium resources. Utility Model Content

[0006] The purpose of this invention is to provide a device for extracting lithium from clay lithium ore, which solves the problem of the existing technology using a separate design for the crushing tank and the mixing tank, resulting in a dispersed overall structure, large space occupation, and unfavorable for a compact factory layout.

[0007] To achieve the above objectives, this utility model provides a device for extracting lithium from clay lithium ore, including a mixing tank and a mixing module installed on top of the mixing tank. A crushing tank is provided on one side of the top of the mixing tank, and a feed pipe is provided on one side of the top of the mixing tank. The bottom of the crushing tank is connected to a connecting pipe through a conical discharge pipe, and the connecting pipe is inserted into the feed pipe.

[0008] The crushing barrel has a support structure on one side for connecting to the ground, and an installation plate is connected to the top of the crushing barrel. The crushing component is installed inside the crushing barrel, and the top of the crushing component is connected to the installation plate through a drive structure. An insertion interface communicating with the inside of the crushing barrel is opened on one side of the crushing barrel. A baffle plate adapted to the insertion interface is provided at the bottom of the inner side of the crushing barrel, and one end of the baffle plate is connected to the side wall of the crushing barrel through a horizontal pushing structure.

[0009] The support structure includes an mounting sleeve and several support rods. The mounting sleeve is fixedly connected to the outer ring bolt of the crushing barrel, and the end of the support rod is fixedly connected to the side wall of the mounting sleeve.

[0010] The top of the outer ring of the feed pipe and one side of the outer ring of the connecting pipe are both connected to a connecting ring, and the two connecting rings are fixedly connected by bolts.

[0011] The crushing assembly includes a rotating rod and several crushing blades connected to the outer ring of the rotating rod. The drive structure includes a drive motor connected to the top of the mounting plate, and the output shaft of the drive motor is connected to the end of the rotating rod.

[0012] The horizontal pushing structure includes a pushing cylinder connected to the side wall of the crushing barrel via an installation sleeve. The output end of the pushing cylinder is connected to a vertical plate, and the bottom end of the vertical plate is connected to the top of the baffle plate.

[0013] The mounting plate is made of metal, and its bottom is bolted to the top of the crushing barrel.

[0014] This invention relates to a device for extracting lithium from clay lithium ore. By compactly arranging the crushing and mixing tanks in space, and directly transferring materials through a conical discharge pipe, connecting pipe, and feed pipe, the device significantly improves the integration between the crushing and acid leaching processes. This avoids the problems of equipment dispersion and large space occupation caused by the separate structure and the use of augers and long-distance connecting pipes for material transport in existing technologies. It facilitates a compact layout of equipment within the factory and optimizes the space of the production line. The crushing components, driven by the drive structure, efficiently crush the clay lithium ore. The released material is controlled by a baffle plate, ensuring that only material reaching the predetermined fineness can enter the mixing tank, thus improving the reliability of material handling. Controllable; the baffle plate is driven by a horizontal pushing structure to open and close the plug-in interface, which is simple and reliable and avoids premature leakage of materials before they are fully crushed; the connecting pipe and the feed pipe are connected by a plug-in joint, which is convenient for installation, disassembly and cleaning and reduces maintenance difficulty; by eliminating the auger conveyor and complex connecting pipes in the traditional design, the number of mechanical transmission parts is reduced, which reduces the equipment failure rate and daily maintenance costs; at the same time, the material enters the mixing tank directly from the crushing tank by gravity, and the conveying path is short and smooth, which effectively avoids the blockage and residue problems caused by pipe bends or material adhesion, ensuring the stable operation of continuous production; the mixing module fully mixes the acid and the ore to ensure uniform and efficient reaction.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, an apparatus for extracting lithium from clay lithium ore according to this embodiment includes a mixing tank 1 and a mixing module 2 installed on the top of the mixing tank 1. A crushing tank 3 is provided on one side of the top of the mixing tank 1, and a feed pipe 8 is provided on one side of the top of the mixing tank 1. The bottom of the crushing tank 3 is connected to a connecting pipe 10 through a conical discharge pipe 9, and the connecting pipe 10 is inserted into the feed pipe 8.

[0025] A support structure for connecting to the ground is provided on one side of the crushing barrel 3. An installation plate 14 is connected to the top of the crushing barrel 3. A crushing component is provided inside the crushing barrel 3. The top of the crushing component is connected to the installation plate 14 through a drive structure. An insertion interface 13 communicating with the inside of the crushing barrel 3 is provided on one side of the crushing barrel 3. A baffle plate 6 adapted to the insertion interface 13 is provided at the bottom of the inner side of the crushing barrel 3. One end of the baffle plate 6 is connected to the side wall of the crushing barrel 3 through a horizontal pushing structure.

[0026] Workflow: When using this equipment to extract lithium from clay lithium ore, the clay lithium ore raw material is first fed into the crushing barrel 3. The crushing barrel 3 is connected to the ground through a support structure on one side to ensure the stability of the equipment during operation. A drive structure is installed on the mounting plate 14 on the top of the crushing barrel 3. The drive structure is connected to the top of the crushing component. After the drive structure is started, it drives the crushing component to rotate at high speed inside the crushing barrel 3, which fully crushes the fed clay lithium ore, reducing its particle size to increase the contact area and reaction efficiency of the subsequent acid leaching reaction. During the crushing process, the baffle plate 6 set at the bottom of the crushing barrel 3 is connected to the side wall through a horizontal pushing structure and is in a closed state, blocking the insertion port 13 to prevent uncrushed material from being discharged prematurely. After the material is crushed to a suitable particle size, the horizontal pushing structure is activated, pushing the baffle plate 6 to move horizontally and remove it from the insertion port 13. The crushed fine material falls into the bottom of the crushing barrel 3 through the insertion port 13. The crushed material is fed into the mixing tank 1 through a conical discharge pipe 9. A connecting pipe 10 is connected to the bottom of the conical discharge pipe 9, and the connecting pipe 10 is inserted into the feed pipe 8 located on the top side of the mixing tank 1. The crushed material enters the mixing tank 1 directly through the connecting pipe 10 and the feed pipe 8. At this time, an appropriate amount of acid leaching solution has been pre-added to the mixing tank 1. The stirring module 2 is installed on top of the mixing tank 1. Activating the stirring module 2 drives the stirring shaft and stirring blades to rotate, thoroughly mixing the incoming crushed material with the acid solution, causing lithium ions to dissolve from the clay mineral lattice and completing the acid leaching lithium extraction reaction. Throughout the process, the crushing and stirring processes are seamlessly connected and transported through the connection structure of the connecting pipe 10 and the feed pipe 8, eliminating the need for additional conveying machinery such as augers or connecting pipes, thus achieving integrated continuous operation. After one batch is processed, the discharge valve at the bottom of the mixing tank 1 is opened to discharge the leachate for subsequent purification treatment, while simultaneously cleaning up residual slag to prepare for the next round of operation.

[0027] Example 2

[0028] Please see Figure 1-5 As shown in the figure, this embodiment of an equipment for extracting lithium from clay lithium ore includes a support structure comprising an mounting sleeve 5 and several support rods 4. The mounting sleeve 5 is bolted to the outer ring of the crushing barrel 3, and the ends of the support rods 4 are fixedly connected to the side walls of the mounting sleeve 5. Specifically, through the cooperation of the mounting sleeve 5 and several support rods 4, the structure is configured as follows: the mounting sleeve 5 is bolted to the outer ring of the crushing barrel 3, the ends of the support rods 4 are fixedly connected to the side walls of the mounting sleeve 5, and the other ends of the support rods 4 are connected to the ground or foundation platform. During equipment operation, the support structure provides multi-point external support to the crushing barrel 3, effectively distributing the equipment vibration load, thereby enhancing the overall stability and vibration resistance of the crushing barrel 3, preventing equipment displacement or loosening of connections due to severe vibrations caused by crushing operations, and ensuring operational safety.

[0029] The crushing assembly includes a rotating rod and several crushing blades 16 connected to the outer ring of the rotating rod. The drive structure includes a drive motor 15 connected to the top of the mounting plate 14. The output shaft of the drive motor 15 is connected to the end of the rotating rod. Specifically, the structure used is filled into the configuration here through the cooperation of the rotating rod, the crushing blades 16, the drive motor 15 and the mounting plate 14. The drive motor 15 is mounted on the top of the metal mounting plate 14, and its output shaft is connected to the rotating rod, driving the rotating rod and the multiple crushing blades 16 mounted on its outer ring to rotate at high speed. This shears, impacts and grinds the clay lithium ore entering the crushing barrel 3, achieving the effect of efficient material crushing, improving the fineness and uniformity of the crushing, and enhancing the contact area and leaching efficiency of the subsequent acid leaching reaction.

[0030] The mounting plate 14 is made of metal. The bottom of the mounting plate 14 is bolted to the top of the crushing barrel 3. Specifically, the mounting plate 14 is bolted to the top of the crushing barrel 3. As the supporting foundation for the drive motor 15 and the crushing components, the mounting plate 14 has high structural strength and rigidity, and can withstand the vibration and torque generated during the crushing process. It achieves the effect of providing a stable mounting platform for the drive structure and crushing components, preventing loosening or deformation during operation, and ensuring long-term stable operation of the equipment.

[0031] Example 3

[0032] Please see Figure 1-5 As shown in this embodiment, an apparatus for extracting lithium from clay lithium ore has connecting rings 7 on the top of the outer ring of the feed pipe 8 and on one side of the outer ring of the connecting pipe 10. The two connecting rings 7 are fixedly connected by bolts. Specifically, by connecting the top of the outer ring of the feed pipe 8 and one side of the outer ring of the connecting pipe 10, and fixing the two connecting rings 7 together by bolts, after the connecting pipe 10 is inserted into the feed pipe 8, the bolt connection between the connecting rings 7 achieves axial limiting and radial alignment of the two, improving the sealing performance and structural stability of the connection, and preventing leakage or detachment during material transportation. At the same time, it is easy to disassemble and clean, improving the reliability of the connection and the convenience of maintenance.

[0033] The horizontal pushing structure includes a pushing cylinder 12 connected to the side wall of the crushing barrel 3 via a mounting sleeve. The output end of the pushing cylinder 12 is connected to a vertical plate 11, and the bottom end of the vertical plate 11 is connected to the top of the baffle plate 6. Specifically, the structure is configured by the cooperation of the pushing cylinder 12, the vertical plate 11, and the baffle plate 6. The pushing cylinder 12 is fixed to the side wall of the crushing barrel 3 via a mounting base, and its output end is connected to the vertical plate 11. The bottom of the vertical plate 11 is connected to the top of the baffle plate 6. When discharge is required, the pushing cylinder 12 is activated, pushing the vertical plate 11 to move the baffle plate 6 horizontally, causing it to exit from the insertion interface 13 and opening the discharge channel. This achieves precise control of the opening and closing action of the baffle plate 6, realizing intermittent discharge during the crushing process, ensuring that the material is fully crushed before entering the mixing barrel 1, and improving process controllability.

[0034] When using the equipment for extracting lithium from clay lithium ore, the clay lithium ore raw material is first fed into the crushing barrel 3. The crushing barrel 3 is connected to the ground through a support structure on one side. The support structure includes a mounting sleeve 5 and several support rods 4. The mounting sleeve 5 is fixed to the outer ring of the crushing barrel 3 with bolts. The end of the support rod 4 is fixedly connected to the side wall of the mounting sleeve 5, and the other end is connected to the ground foundation to ensure the stability of the equipment during operation. A metal mounting plate 14 is connected to the top of the crushing barrel 3. The bottom of the mounting plate 14 is firmly fixed to the top of the crushing barrel 3 with bolts, providing a high-strength support platform. A drive motor 15 is installed as part of the drive structure. Its output shaft is connected to a rotating rod in the crushing assembly. Multiple crushing blades 16 are installed on the outer ring of the rotating rod. After the drive motor 15 is started, it drives the rotating rod and the crushing blades 16 to rotate at high speed, shearing, impacting and grinding the input clay lithium ore to achieve efficient crushing. During the crushing process, a baffle plate 6 set at the bottom of the crushing barrel 3 blocks the insertion interface 13 opened on its side wall to prevent insufficiently crushed material from being discharged prematurely. One end of the baffle plate 6 is controlled by a horizontal pushing structure, which includes a pushing cylinder 12 fixed to the side wall of the crushing barrel 3. The output end of the cylinder 12 is connected to the vertical plate 11, and the bottom end of the vertical plate 11 is connected to the top of the baffle plate 6. When the material reaches the predetermined fineness, the cylinder 12 is activated, pushing the vertical plate 11 to move the baffle plate 6 horizontally, causing it to move away from the insertion port 13 and open the discharge channel. The crushed fine material falls into the bottom of the crushing barrel 3 through the insertion port 13 and is conveyed downward through the conical discharge pipe 9. The bottom of the conical discharge pipe 9 is connected to the connecting pipe 10, which is inserted into the feed pipe 8 on one side of the top of the mixing barrel 1 to realize the direct transfer of materials. To improve the reliability of the connection, the top of the outer ring of the feed pipe 8 and one side of the outer ring of the connecting pipe 10 are both equipped with connecting pipes. The connecting ring 7 is fixedly connected to the other two rings by bolts to ensure a stable connection and good sealing, preventing leakage or detachment. The crushed material enters the mixing tank 1 through the connecting pipe 10 and the feed pipe 8. At this time, acid leaching solution has been added to the mixing tank 1. The stirring module 2 is installed on the top of the mixing tank 1. After starting, it drives the internal stirring mechanism to rotate, which fully mixes and stirs the ore and acid solution, so that lithium ions dissolve from the mineral lattice and complete the acid leaching reaction. The whole process realizes the integration of crushing and stirring processes. The material is transported by gravity flow, without the need for intermediate conveying devices such as screw conveyors, ensuring continuous and stable operation.

[0035] The equipment for extracting lithium from clay lithium ore uses a mixing tank 1 as the acid leaching reaction vessel, with a stirring module 2 installed on top to achieve uniform stirring and improve reaction efficiency. A crushing tank 3 is located on one side of the top of the mixing tank 1, forming a compact layout that reduces the equipment's footprint and optimizes factory space. The crushing components inside the crushing tank 3 are driven by a motor 15 that rotates the crushing blades 16 at high speed via a rotating rod, achieving efficient crushing of the clay lithium ore, increasing the material's specific surface area, and enhancing the subsequent acid leaching effect. The mounting plate 14 is made of metal and connected to the top of the crushing tank 3 with bolts, providing a robust structure capable of withstanding vibration and torque, and offering a stable mounting foundation for the drive motor 15 and the crushing components. The support structure consists of a mounting sleeve 5 and multiple support rods 4. The mounting sleeve 5 is bolted to the outer ring of the crushing tank 3, and one end of each support rod 4 is connected to the mounting sleeve 5, while the other end is grounded, effectively distributing the vibration load during equipment operation and enhancing overall stability. The structure is designed to prevent loosening or displacement due to vibration. A baffle plate 6 is located at the bottom of the crushing drum 3 and works in conjunction with the insertion port 13 to control the timing of material discharge during the crushing process. The horizontal pushing structure is driven by a pushing cylinder 12, which moves the baffle plate 6 horizontally via a vertical plate 11, thus opening and closing the insertion port 13. This ensures that only fully crushed material can enter the next process, improving process controllability. The conical discharge pipe 9 facilitates smooth material discharge and reduces residue. The connecting pipe 10 and the feed pipe 8 are connected by a plug-in method and secured with bolts between connecting rings 7, achieving quick connection and reliable sealing, facilitating disassembly, cleaning, and maintenance. This structure eliminates the complex auger conveying system and long-distance connecting pipelines found in traditional equipment, reducing the number of mechanical parts and lowering the failure rate and maintenance costs. Material is transferred by gravity, with a short and smooth path, avoiding blockages and residue problems, and ensuring continuous production.
