Production device for preparing polyferric sulfate

A production device for preparing polyferric sulfate relates to the technical field of polyferric sulfate production, and comprises a high-pressure reaction kettle, a dissolving tank, a catalyst material tank and a liquid oxygen tank which are all communicated with the high-pressure reaction kettle, and a pressure-resistant outer layer coated outside the dissolving tank, a closed chamber is formed by matching with the dissolving tank; and the heating assembly is communicated with the high-pressure reaction kettle and the closed chamber, and is used for conveying the mixed material in the high-pressure reaction kettle into the closed chamber, so that the mixed material heats the dissolving tank, and meanwhile, the mixed material in the closed chamber is conveyed back into the high-pressure reaction kettle, so that the cyclic utilization of the mixed material is realized. With the adoption of the technical scheme, the mixed material subjected to polymerization reaction in the high-pressure reaction kettle passe
