Description

Technical Field

[0001] This utility model relates to the field of lithium metal transfer technology, and in particular to a lithium metal storage and transfer device. Background Technology

[0002] Lithium is a metallic element, known as a green energy metal and "white oil," and is widely used in energy storage, chemical industry, medicine, metallurgy, electronics industry and other fields. Lithium liquid is being used more and more widely in our lives, and the demand is increasing, especially in the battery field.

[0003] For example, the lithium metal storage and transfer device disclosed in the utility model with authorization announcement number CN217969606U collects liquid lithium metal produced by the electrolytic cell in an argon atmosphere using a lithium collecting furnace carried by a transport vehicle. This effectively avoids lithium metal nitridation and ensures product quality. Moreover, the process of collecting liquid lithium metal produced by the electrolytic cell through the lithium collecting furnace does not require long-term close-range manual operation, which helps reduce labor intensity and improve work efficiency. By setting a temperature control layer on the outside of the lithium collecting furnace, the lithium metal is kept in a semi-solid state during transportation and in a liquid state when transferred to the refining equipment, which helps improve overall work efficiency.

[0004] The existing technology still has the following problems when used:

[0005] Lithium metal, in its liquid state, is a viscous fluid with strong viscosity and adhesion. Therefore, when liquid lithium metal is stored inside the lithium collecting furnace of this device, some of the liquid lithium may adhere to the inner wall of the furnace. If the device is not used and the internal temperature of the collecting furnace gradually decreases, the liquid lithium adhering to the furnace will solidify. Over time, air may gradually enter the furnace, at which point the lithium metal may react chemically with gases such as nitrogen in the air to form compounds such as lithium nitride. If these compounds remain inside the furnace, they will affect the concentration of elemental lithium in the next storage and transportation. Furthermore, if the lithium metal remaining inside the furnace is not collected in time, it will also result in waste. Utility Model Content

By setting up a scraping component, the lithium metal solution adhering to the inner wall of the insulation tank and the hopper can be scraped off during use. The scraped lithium metal will accumulate on the top surface of the valve. By opening the valve, the residual lithium metal can be collected, preventing the lithium metal from remaining inside the insulation tank and reacting with the gas in the air, thus affecting the concentration of elemental lithium in the next transport and reducing the waste of lithium metal.

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0025] Example

[0026] Please refer to Figure 1 and Figure 3 As shown, this utility model provides a lithium metal storage and transfer device, including a vehicle body 1. The four corners of the bottom surface of the vehicle body 1 are provided with casters 11 for moving the vehicle body 1. A push handle 10 for pushing the vehicle body 1 is fixedly connected to one side of the vehicle body 1. A thermal insulation tank 2 for storing liquid lithium metal is fixedly installed inside the vehicle body 1. The interior of the thermal insulation tank 2 is lined with insulation materials such as cotton boards, which can greatly slow down the rate of temperature drop inside the thermal insulation tank 2, thereby reducing the solidification rate of the liquid lithium metal placed inside the thermal insulation tank 2. A sealing cover 5 is movably installed on the top surface of the thermal insulation tank 2. The top surface of the sealing cover 5 is provided with an inlet 13. An outlet 14 is provided on one side of the inlet 13. An vent pipe 16 is provided on one side of the outlet 14. An inlet 16 is provided on one side of the vent pipe 16. The gas pipe 15, with the outlet 14, inlet 13, outlet pipe 16, and bottom of inlet pipe 15 all passing through the sealing cap 5 and connected to the heat preservation tank 2, allows argon gas to be injected into the inlet pipe 15 during use. Since argon gas is an inert gas, it does not react with metallic lithium, and its density is greater than that of air. Therefore, when argon gas enters the heat preservation tank 2, it can push the air inside the heat preservation tank 2 upward until the air is completely squeezed out from the outlet pipe 16, thus filling the heat preservation tank 2 with pressure. At this time, liquid metallic lithium can be transported into the heat preservation tank 2 through the inlet 13, preventing metallic lithium from reacting with gases such as nitrogen in the air, which would affect the concentration and quality of metallic lithium.

[0027] It is worth noting that the inlet 13, outlet 14, air inlet pipe 15 and air outlet pipe 16 of this device are all equipped with solenoid valves. During use, the feeding, discharging, air intake and exhaust are controlled by switching the solenoid valves to prevent the inside of the heat preservation tank 2 from being constantly connected to the external environment, which would cause air to enter the inside of the heat preservation tank 2.

[0028] When using this device, place it in the designated location. Before storing lithium metal, fill the interior of the insulation tank 2 with argon gas through the inlet pipe 15. At this time, the air inside the insulation pipe flows out through the outlet pipe 16. When the interior of the insulation tank 2 is filled with argon gas, connect it to the external lithium metal raw material device through the feed port 13, so that liquid lithium metal can flow into the interior of the insulation tank 2. Through the push handle 10 and the moving wheels 11, the vehicle body 1 and the insulation tank 2 can be transported to the designated location. After arriving at the designated location, connect it to the external extraction device through the discharge port 14, so that the liquid lithium metal inside the insulation tank 2 can be extracted. This completes the transfer of lithium metal.

[0029] As a further implementation of this embodiment, such as Figure 1-5As shown, the bottom of the heat preservation tank 2 is connected to the feeding hopper 3. The bottom surface of the sealing cover 5 is provided with a scraping assembly for scraping off the metallic lithium adhering to the inner wall of the heat preservation tank 2. The scraping assembly consists of a rotating rod 17, a rotating plate 18, a scraper 19, a connecting block 20, a mounting rod 21, a connecting plate 22, a first spring 24, a scraper 23, and a second spring 25. The rotating rod 17 is fixedly connected to the bottom surface of the sealing cover 5. The rotating plates 18 are symmetrically arranged on both sides of the rotating rod 17. Multiple second springs 25 are provided inside the two rotating plates 18. One end of the second spring 25 is connected to the scraper 19, and one side of the scraper 19 extends out of the outer side of the rotating plate 18. The extended end of the scraper 19 contacts the inner wall of the heat preservation tank 2. When the rotating plate 18 rotates, it drives the scraper 19 to rotate along the inner wall of the insulation tank 2, thereby scraping off the metallic lithium adhering to the inner wall of the insulation tank 2. Furthermore, the reaction force of the second spring 25 pushes the scraper 19 towards the inner wall of the insulation tank 2, causing one side of the scraper 19 to adhere tightly to the inner wall of the insulation tank 2. A connecting block 20 is fixedly connected to the bottom end of the rotating rod 17. Mounting rods 21 are fixedly connected to both sides of the connecting block 20. A connecting plate 22 is fixedly connected to one side of the mounting rods 21. Multiple first springs 24 are provided inside the connecting plate 22. One end of each first spring 24 is connected to a scraper 23, and one side of the scraper 23 extends outward from the outer side of the connecting plate 22. The extended end contacts the inner wall of the hopper 3, and the connecting plate 22 and the mounting rod 21 are inclined at an angle parallel to the hopper 3. This allows the scraper 23 to be pushed against the inner wall of the hopper 3 by a spring, ensuring close contact between the scraper 23 and the inner wall. When the scraper 23 rotates, it scrapes off the lithium metal adhering to the inner wall of the hopper 3. A disassembly assembly for removing the sealing cover 5 and the scraping component is provided between the sealing cover 5 and the insulation tank 2. This disassembly assembly consists of ear plates 8, bolts 7, and fixing blocks 6. Two ear plates 8 are fixedly connected to both sides of the sealing cover 5, and two fixing blocks 6 are fixedly connected to both sides of the insulation tank 2. The bolts 7 pass through the ear plates 8 and... The fixing block 6 and the bolt 7 are connected to the ear plate 8 and the fixing block 6 by threads. By rotating the bolt 7, the bolt 7 can be removed from the inside of the ear plate 8 and the fixing block 6. At this time, the sealing cover 5 can be lifted upward to remove the sealing cover 5 and the scraping assembly from the inside of the heat preservation tank 2. The scraping assembly can be removed to remove the metallic lithium adhering to its surface, which is convenient for the subsequent use of the scraping assembly and also reduces the waste of metallic lithium. The top surface of the sealing cover 5 is equipped with a motor 9, and the output end of the motor 9 is connected to the rotating rod 17. The bottom surface of the hopper 3 is equipped with a valve 4 for opening and closing the hopper 3. The inner side of the vehicle body 1 is equipped with a collection box 12, and the collection box 12 is placed directly below the hopper 3.

[0030] It is worth noting that the valve 4 used in this device is also a solenoid valve. The operator can control the opening and closing of the valve 4 by electromagnetic force, so that the operator does not need to manually open and close the valve 4, thus preventing the operator from being burned by the overheated liquid lithium metal when opening and closing the valve 4.

[0031] When this device is used further, after the liquid lithium metal inside the insulation tank 2 has been transferred, the motor 9 is started. The motor 9 drives the rotating rod 17 to rotate, which in turn drives the rotating plates 18 on both sides to rotate. The rotating plates 18 drive the scraper 19 to rotate. When the scraper 19 rotates, it can scrape off the lithium metal adhering to the inner wall of the insulation tank 2. The scraped lithium metal accumulates on the top surface of the discharge hopper 3. At the same time as the rotating rod 17 rotates, it can drive the connecting block 20 to rotate. The connecting block 20 drives the mounting rods 21 on both sides to rotate, and the mounting rods 21 drive the connecting plate 2... 2. When the connecting plate 22 rotates, the scraper 23 rotates along the inner wall of the hopper 3. When the scraper 23 rotates, it can scrape off the liquid lithium metal adhering to the inner wall of the hopper 3. The scraped lithium metal also falls to the top surface of the valve 4. Opening the valve 4 allows the lithium metal falling on the valve 4 to fall into the inside of the collection box 12. In this way, the lithium metal remaining in the heat preservation tank 2 can be recovered, reducing the waste of lithium metal and preventing the residual lithium metal from reacting with the gas in the air, thus affecting the concentration and quality of the next lithium metal.

[0032] Specific working principle: The device is placed in a designated position. Argon gas is introduced into the insulation tank 2 through the inlet pipe 15 to prevent the liquid lithium metal from reacting with the air inside the tank, thus affecting the quality of the lithium metal. The device is connected to an external lithium metal production unit through the feed port 13, allowing the liquid lithium metal stored inside the insulation tank 2 to be transferred to a designated location via the push handle 10 and casters 11. The liquid lithium metal is then extracted from the insulation tank 2 through the discharge port 14, thus completing the transfer of lithium metal. The motor 9 is started, driving the rotating rod 17 to rotate. The rotating rod 17 drives the rotating plate 18 to rotate, which in turn drives the scraper 19 to rotate along the inner wall of the insulation tank 2. This scrapes away the liquid lithium metal adhering to the inner wall of the insulation tank 2. Simultaneously, the rotating rod 17 also... The rotating connecting block 20 drives the mounting rod 21 to rotate. As the mounting rod 21 passes through, the connecting plate 22 drives the scraper 23 to rotate. When the scraper 23 rotates along the inner wall of the hopper 3, it can scrape off the liquid lithium metal adhering to the inside of the hopper 3. The scraped liquid lithium metal falls to the top of the valve 4. Opening the valve 4 allows the lithium metal remaining inside the insulation tank 2 to fall into the collection box 12, thus recovering the residual lithium metal, reducing the waste of lithium metal, and preventing the residual lithium metal from reacting with the gas in the air and affecting the concentration and quality of the lithium metal in the next transport. By removing the bolt 7, the sealing cover 5 and the scraper assembly can be removed from the inside of the insulation tank 2, thereby removing the lithium metal adhering to the scraper assembly, further reducing the waste of lithium metal, and facilitating the subsequent use of the scraper assembly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
