Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a raw material scattering device for the production of anhydrous aluminum fluoride. Background Art

[0002] In the existing production process of anhydrous aluminum fluoride, aluminum hydroxide is transported to the first-stage airflow reactor after being measured. Under the action of positive pressure airflow, aluminum hydroxide enters the second and third-stage airflow reactors with the airflow to complete the dehydration reaction. Since the aluminum hydroxide material contains 3-6% moisture, the material is in block form when passing through the spiral discharge port. Under the action of gravity, it will directly fall into the top bed sieve plate of the fluidized bed, resulting in the inability of aluminum hydroxide to complete the dehydration reaction in the first, second and third-stage airflow reactors, affecting the reaction efficiency in the fluidized bed, and it is very easy to cause the material containing a large amount of moisture to sinter on the top bed sieve plate and block the sieve plate holes, seriously affecting normal production. In addition, since the material cannot enter the fluidized bed evenly and the material accumulates on the top bed, it is easy to cause high pressure in the middle of the fluidized bed system and unstable system production. In response to the above problems, the inventors proposed a raw material scattering device for the production of anhydrous aluminum fluoride to solve the above problems. Utility Model Content
