Iron phosphate heating and drying device

The invention relates to the technical field of battery raw materials, in particular to an iron phosphate heating and drying device which comprises a rack and a belt conveying mechanism, the belt conveying mechanism is installed on the rack, a feeding port and a discharging port are formed in the two ends of the belt conveying mechanism respectively, and a belt, used for conveying iron phosphate, on the belt conveying mechanism is a conveyor belt with skirt edges and without partition plates. The rack comprises at least three groups of portal frames which are arranged at intervals, the portal frames are straddled above the skirt-edge partition-plate-free conveying belt, lifting driving mechanisms are arranged at the tops of the portal frames, electric heating mechanisms are vertically assembled on the portal frames in a sliding mode, and the lifting driving mechanisms are used for driving the electric heating mechanisms to ascend and descend. According to the iron phosphate heating and drying device, hot air
