Problems solved by technology

[0004] (1) The raw materials for the production of solid-phase fluoride have the problems of large density and particle size differences, and it is difficult to find an industrial-scale reactor that can meet its production requirements at the same time
[0005] (2) At present, the production equipment used in the industry is mainly fixed bed production equipment such as tube furnaces. The concentration of fluorinating agent at the front end and tail end (or bottom and top) of the reactor is not uniform, and the materials are manually loaded and unloaded. The way of stacking or thin-layer tiling is in contact with fluorinating agents, and there are problems such as long fluorination reaction time period, low degree of mechanization, uneven fluorination, and low production efficiency.
