Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, in particular to a lithium chloride feeding device. Background Art

[0002] Lithium chloride is easily soluble in water due to its unique ionic bond. At room temperature, it appears as a white crystalline powder or small particles. Its hydration capacity gradually increases with decreasing temperature, making it susceptible to deliquesce. After deliquescing, it becomes alkaline and corrosive, which also degrades its chemical properties, resulting in poor product quality. Therefore, in the industrial production of electrolytic lithium metal, the lithium chloride raw material often undergoes a heating treatment before entering the electrolytic cell.

[0003] Currently, the raw materials are added manually into the electrolytic cell. This method has some disadvantages. On the one hand, the raw materials are in direct contact with the air, and the moisture in the air will adhere to the surface of the raw materials, resulting in a high water content of the raw materials, which not only affects the life of the electrolytic cell, but may even cause an explosion. On the other hand, the material scatters during the feeding process, resulting in a high loss rate and difficult cleaning, and will cause irritation and corrosion to the human eyes, causing great harm to the health of the workers.

An operating platform can be provided at the observation port 13 to facilitate staff observation and removal of the ton bag binding ropes, thereby allowing the material in the ton bag unpacker 1 to fall. The preheating silo 2 is provided below the ton bag unpacker 1. The preheating silo 2 is used to receive the lithium chloride material in the ton bag unpacker 1 and preheat the material. In this embodiment, the lower portion of the ton bag unpacker 1 is provided with a crusher discharger 7 for crushing large pieces of material. The lower portion of the crusher discharger 7 is connected to the preheating silo 2. The main function of the crushing discharger 7 is to break up the block materials caused by moisture in the ton bag unpacking machine 1. After the ton bag binding rope is released, the materials are crushed by the crushing discharger 7 and then enter the preheating silo 2 for heating.

[0022] The preheating silo 2 is provided with a heating wire on its inner wall and an insulation layer on its outer wall. When the heating wire is energized, it generates heat that exchanges heat with the material in the preheating silo 2, thereby preheating the material.

The material in the preheating silo 2 slides into the vibrating elevator 8 through the discharge hopper 9 under the action of gravity. The vibrating elevator 8 is equipped with an auger conveying device to lift the material at the bottom to the top and drop it into the material silo 3 through the discharge port.
