[0002] A reaction kettle is a reaction vessel for physical or chemical reactions, with excellent chemical stability and high structural strength. Through the structural design and parameter configuration of the container, heating, evaporation, cooling, and mixing functions at low and high speeds required by the process are achieved, and it is widely used in the production of petroleum, chemical industry, rubber, pesticides, medicine, food, coatings, paints, etc. In the preparation of lithium dihydrogen phosphate, lithium dihydrogen phosphate needs to be put into the reaction kettle for reaction.

[0003] Since the preparation of lithium dihydrogen phosphate requires a relatively high temperature, when the high-temperature hot gas generated during the preparation of lithium dihydrogen phosphate drifts through the feed hopper, it is easy to cause a relatively high temperature near the feed hopper. At the same time, when adding materials to the feed hopper, the steam in the kettle body is also easy to scald people, which is not convenient for the staff to feed materials into the reaction kettle through the feed hopper, not convenient for the normal operation of the staff, and reduces the feeding efficiency during the preparation of lithium dihydrogen phosphate. Content of the Utility Model

[0004] The utility model provides a reaction kettle for preparing lithium dihydrogen phosphate, aiming to solve the problem that it is inconvenient to add materials to the feed hopper during the operation of the currently used reaction kettle proposed in the above background technique.
