DETAILED DESCRIPTION
[0015] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0016] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.
[0017] A metal lithium automatic purification interlocking system, reference Figure 1 , including a purification container 1, a first transition container 3, a second transition container 4 and a collection container 5 which are sequentially connected through a connecting pipe 5. The connecting pipe 5 is provided with a one-way valve 11 and a stop valve 12 to prevent the backflow of liquid lithium.
[0018] In this embodiment, the purification container 1 is a feeding furnace, the first transition container 3 is a distillation furnace, the second transition container 4 is a primary battery-level lithium collection furnace, and the collection container 5 is a secondary battery-level lithium collection furnace. The outer walls of the feeding furnace, the distillation furnace, the primary battery-level lithium collection furnace, and the secondary battery-level lithium collection furnace are all provided with heat-conducting jackets. Since heat-conducting jackets are a very existing technology and heat-conducting oil is one of the commonly used heating methods, no further description is given here.
[0019] The feeding end of the feeding furnace is connected to the industrial-grade lithium collection furnace through the connecting pipe 5. The feeding furnace is provided with a low liquid level detection device 6, a high liquid level detection device 7, a vacuum solenoid valve 9, an argon solenoid valve 10 and a pressure transmitter 8. The stop valve 12 of the connecting pipe 5 between the feeding furnace and the industrial-grade lithium collection furnace is controlled by the high liquid level detection device 7 in the feeding furnace. The stop valve 12 of the connecting pipe 5 between the distillation furnace and the feeding furnace is controlled by the low liquid level detection device 6 in the feeding furnace.
[0020] The primary battery-level lithium collection furnace is provided with a low liquid level detection device 6, a high liquid level detection device 7, a vacuum solenoid valve 9, an argon solenoid valve 10 and a pressure transmitter 8. The stop valve 12 on the connecting pipe 5 between the distillation furnace and the primary battery-level lithium collection furnace is controlled by the high liquid level detection device 7 in the primary battery-level lithium collection furnace.
[0021] The secondary battery-level lithium collection furnace is provided with a low liquid level detection device 6, a high liquid level detection device 7, a vacuum solenoid valve 9, an argon solenoid valve 10 and a pressure transmitter 8. The stop valve 12 on the connecting pipe 5 between the primary battery-level lithium collection furnace and the secondary battery-level lithium collection furnace is controlled by the low liquid level detection device 6 in the primary battery-level lithium collection furnace and the high liquid level detection device 7 in the secondary battery-level lithium collection furnace.
[0022] When the industrial-grade lithium collection furnace filters the liquid lithium and sends it to the feeding furnace, the feeding furnace heats the liquid lithium to process it. After the processing is completed, the feeding furnace sends the liquid lithium to the distillation furnace for distillation and filtration. During the distillation and filtration process, the liquid lithium comes to the first-level battery-level lithium collection furnace for rapid cooling. After cooling, the liquid lithium goes from the first-level battery-level lithium collection furnace to the second-level battery-level lithium collection furnace for secondary heat preservation and filtration.
[0023] During the feeding process of liquid lithium, the air pressure in the feeding furnace, the first-level battery-level lithium collection furnace and the second-level battery-level lithium collection furnace can be adjusted by controlling the cooperation of the vacuum solenoid valve 9, the argon solenoid valve 10 and the pressure transmitter 8, so as to achieve the purpose of stable feeding. When the liquid level of the liquid lithium in the feeding furnace, the first-level battery-level lithium collection furnace and the second-level battery-level lithium collection furnace is higher than or equal to the high liquid level detection device 7, the high liquid level detection device 7 controls the corresponding stop valve, and the liquid lithium is no longer fed into the feeding furnace, the first-level battery-level lithium collection furnace and the second-level battery-level lithium collection furnace, and the liquid lithium in the feeding furnace, the first-level battery-level lithium collection furnace and the second-level battery-level lithium collection furnace can continue to be discharged. When the liquid level of the liquid lithium in the feeding furnace, the first-level battery-level lithium collecting furnace and the second-level battery-level lithium collecting furnace is lower than or equal to the low liquid level detection device 6, the liquid lithium in the feeding furnace, the first-level battery-level lithium collecting furnace and the second-level battery-level lithium collecting furnace is no longer discharged, and the liquid lithium continues to be fed into the feeding furnace, the first-level battery-level lithium collecting furnace and the second-level battery-level lithium collecting furnace. When the liquid level is above the low liquid level detection device 6 and below the high liquid level detection device 7, the liquid lithium in the feeding furnace, the first-level battery-level lithium collecting furnace and the second-level battery-level lithium collecting furnace is kept in both the feeding and discharging state.
