Description

Technical Field

[0001] The invention relates to the technical field of metal lithium production, in particular to a device for directional cooling of metal lithium. Background Art

[0002] As the core of new energy negative electrode materials, metallic lithium plays a vital role in the lithium-ion battery industry. Its excellent electrochemical properties, lightweight characteristics and high energy density make metallic lithium widely used in new energy vehicles, aerospace, and portable electronic devices. However, the production process of metallic lithium, especially the casting process after purification, has extremely strict requirements on cooling technology.

[0003] In industrial production, metallic lithium liquid needs to be cast in a closed environment protected by argon gas to avoid reaction with oxygen and water vapor in the air. During the casting process, the cooling rate of the lithium liquid needs to be precisely controlled to ensure that the lithium ingots can be demolded smoothly and maintain uniform hardness and color. If the cooling rate is too fast, the hardness of the lithium ingot may be too high, affecting subsequent processing and use. If the cooling rate is too slow, the temperature of the lithium ingot may be too high, resulting in demolding failure or uneven quality of the lithium ingots.

[0004] After searching, Chinese patent CN117680626A discloses a lithium ingot rotary casting device, which includes: a rotary ingot casting table, a quick cooling mold, a liquid lithium casting pipeline, an oil cooler, and a rotary drive. The quick cooling mold is installed on the rotary ingot casting table, the oil cooler is connected to the quick cooling mold, and provides circulating cooling oil for the quick cooling mold. The outlet of the liquid lithium casting pipeline is placed on the opening of the quick cooling mold to provide liquid lithium for the quick cooling mold. A rotary drive is provided in the rotary ingot casting table to drive the rotary ingot casting table to rotate. The invented device can realize continuous casting of liquid metal lithium in an argon protection atmosphere, quickly cool to the demolding temperature, and realize automatic demolding.

[0005] After searching, Chinese patent CN117226054A discloses a high-capacity battery-grade automatic casting device and casting method of lithium metal, including a crucible, an automatic casting machine, an argon circulation glove box, an oil cooling unit and an automatic casting control cabinet. The crucible is arranged at the upper part of the argon circulation glove box, and the automatic casting machine is arranged at the bottom of the argon circulation glove box. The automatic casting machine includes an automatic casting lifting device, an automatic demoulding device, an automatic oiling device, an automatic oil cooling clamping device, an automatic cleaning device and a circular track device. The oil cooling unit is connected to the automatic oil cooling clamping device, and the automatic casting control cabinet is electrically connected to the automatic casting machine and the oil cooling unit. The invention realizes the automatic casting of lithium metal in the argon circulation glove box, can cast molds of different heights, reduces the splashing of lithium liquid, and has a fast cooling speed and high production efficiency.

[0006] After searching, Chinese patent CN117182054A discloses a lithium ingot casting system and a lithium ingot casting method in a closed environment for metallic lithium, which are used to receive high-temperature liquid metallic lithium after distillation and purification for casting, cutting and bagging in a mold, including a glove box and a mold arranged in the glove box, the glove box having a gas circulation module, which is connected to the inside of the glove box and controls the gas environment inside the glove box, the glove box having at least two independent chambers, namely a preparation chamber and an operation chamber, at least one of the preparation chamber and the operation chamber having a buffer chamber connected to the outside for material exchange, the buffer chamber having a detachable sealing structure on the port connecting the outside and the inside for sealing, and realizing independent gas environment control by connecting the gas circulation module, the mold being arranged in the operation chamber, the mold comprising a cooling bracket and a plurality of mold barrels arranged on the cooling bracket, the mold barrel being detachably connected to the cooling bracket.

[0007] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art: At present, there are many kinds of lithium metal casting cooling devices on the market, but these devices still have some problems in practical application. For example, some devices use cooling oil as cooling medium, such as Chinese patent CN117680626A and Chinese patent CN117226054A. Although they can achieve rapid cooling, the excessively fast cooling speed often leads to excessive hardness of lithium ingots, which is not suitable for the production of purified battery-grade lithium metal. In addition, the use of cooling oil may also introduce impurities, causing secondary pollution of lithium ingots, seriously affecting product quality. Although other devices use gas cooling, such as Chinese patent CN117182054A, it is difficult to achieve uniform blowing of cooling air in a multi-mold production environment, which leads to insufficient cooling of the lithium liquid in some molds and excessively high temperatures of the lithium ingots, resulting in demolding failure, uneven hardness or discoloration of the lithium ingots, etc. These problems not only affect the production efficiency and quality of the lithium ingots, but also increase production costs and safety risks.

The electric control cabinet 600 is fixedly installed on the outer side of the lower cabinet 100 to provide electrical support for the operation of the entire device. Specifically, during the operation, the operator first opens the first sealing plate 220, places the lithium ingot casting mold on the conveying mechanism 400, and closes the first sealing plate 220 to ensure the argon protective atmosphere in the glove box 200.
