[0002] Ferric phosphate is an important industrial material, especially in the preparation of lithium iron phosphate, which requires high-temperature solid-state reaction synthesis. The calcination of ferric phosphate is usually carried out in a high-temperature rotary kiln, a high-temperature treatment process used to remove water of crystallization and improve the purity of the material. The high-temperature rotary kiln has a transmission device that drives the inclined drum to rotate, ensuring that the material is heated evenly in the kiln. Existing transmission devices generally have a gear ring set on the outside of the rotary kiln. The motor drives the gear to rotate, and the rotation of the rotary kiln is achieved through the meshing of the gear and the gear ring. The gear meshing points need to be manually lubricated frequently during the gear rotation. The rotation of the gears can easily cause fingers or tools to be caught, affecting the safety of on-site operators. To solve this problem, a new type of high-temperature rotary kiln for ferric phosphate is needed. Utility Model Content
