The invention discloses a novel
lithium iron phosphate roasting device, and particularly relates to the technical field of battery positive
electrode materials, the device comprises a
lithium iron phosphate kiln, a stock bin and a
heat exchanger, the inner part of the inner
kiln is provided with a material lifting mechanism for improving the material
heating time and speed; one end of the
lithium iron phosphate kiln is provided with a
piston material pushing device which enables materials to be conveyed in an integral pushing mode, through the design of the material lifting mechanism and the intermittent material lifting plates in the inner kiln, it is guaranteed that the materials move forwards in a spiral pulsation mode, and meanwhile the material contact area is increased; the
staying time of materials in the kiln can be prolonged, the
heating time and the heating speed of the materials are guaranteed, the
structural stability of the high-temperature
barrel kiln body and the movement mixing of the materials can be enhanced through the spiral belt type intermittent guide plates, the
heat transfer efficiency is effectively improved, meanwhile, in the flowing process of gas in the
barrel, the air speed of the wall face of the
barrel is reduced, and raised dust is greatly reduced; and the probability that the material which is not fully heated escapes in a flying dust form is reduced.
