摘要：
The present invention relates to the field of lithium battery raw material preparation technologies, in particular to a production apparatus for hydrothermal synthesis of lithium iron phosphate. The production apparatus comprises first stirring devices, a preheating device, a second stirring device, and a drying device, wherein there are two first stirring devices, and the preheating device comprises a housing, a heating box, two feeding pumps, two first transfer assemblies, and several first heating tubes; the two first transfer assemblies each comprise an inlet pipe, an outlet pipe, and several transfer branch tubes. In the present application, the arrangement of multiple transfer branch tubes increases the heated surface area of the slurry, enhances the thermal conduction efficiency, and improves the heating effect. The equidistant arrangement of the transfer branch tubes ensures uniform heating of the slurry within the multiple transfer branch tubes, guaranteeing the heating effect. The arrangement of the preheating device can reduce the heating time of the slurry, thereby enhancing the heating effect
