Description

Technical Field

[0001] The utility model relates to the technical field of lithium hexafluorophosphate production, in particular to a device for improving the quality of lithium hexafluorophosphate products. Background Art

[0002] Lithium hexafluorophosphate is an inorganic compound and a white crystalline powder. It is easily soluble in water, low concentration methanol, ethanol, acetone, carbonates and other organic solvents. It is mainly used as an electrolyte material for lithium-ion batteries.

[0003] After searching, a Chinese utility model patent disclosed a device for reducing the iron ion content in lithium hexafluorophosphate products with a publication number of CN216125631U. Its technical solution is: the phosphorus pentafluoride gas storage tank is connected to the first inlet at the top of the reactor through an air pump and an air pipe, the lithium fluoride hydrogen fluoride solution storage tank is connected to the second inlet at the top of the reactor through an infusion valve and an infusion pipe, a product agitator is installed in the reactor, and the outer wall of the reactor is provided with a circulating cooling chamber, a cooling water inlet is provided on one side of the circulating cooling chamber, and a cooling water outlet is provided on the other side; a discharge port is provided at the bottom of the reactor, and a plurality of supporting legs are provided on the outside of the discharge port of the reactor. The beneficial effect is: its structure is simple, easy to clean and dry, and convenient to maintain, and can effectively prevent the inlet pipeline of the synthesis tank from being blocked, thereby effectively avoiding the introduction of rust and other foreign matter when manually dredging the gas pipe, thereby reducing the iron ion content in the lithium hexafluorophosphate product and improving the product quality of lithium hexafluorophosphate.

[0004] However, the device often lacks the function of improving the utilization rate of cooling water. When the device is in use, the cooling water is poured into the cooling device when cooling the device, and is directly discharged after cooling, resulting in a reduction in the utilization rate of water resources. Not only that, the device also lacks a cleaning function. When the device is used for a long time, the device cannot be cleaned, which affects the production quality of lithium hexafluorophosphate.
