In addition, manual feeding is prone to spilling materials, causing environmental pollution. In addition, due to the production process of phosphorus pentachloride, the finished barreled phosphorus pentachloride raw materials are severely agglomerated, which has a certain impact on the phosphorus pentachloride transportation efficiency and the quality of lithium hexafluorophosphate products.

[0003] In summary, the prior art has many instabilities and dangers in the process of adding phosphorus pentachloride into the production of lithium hexafluorophosphate, so it is necessary to develop a device for automatically, safely and efficiently conveying phosphorus pentachloride.
