The invention relates to the field of inorganic polymer fiber material preparation, in particular to a calcium polyphosphate fiber preparing method, and further discloses production equipment for preparing calcium polyphosphate fibers through the method. The production equipment comprises a high-temperature melting furnace, a wiredrawing device and a cooling device. The high-temperature melting furnace comprises a molten pool kiln and a wiredrawing pool kiln. The molten pool kiln and the wiredrawing pool kiln are communicated through a liquid flow channel. The wiredrawing device is arranged on the outer side of the wiredrawing pool kiln. The molten pool kiln, the liquid flow channel and the wiredrawing pool kiln are internally provided with electrodes. The bottom of the wiredrawing pool kiln is provided with a downwards-leaking device. According to the calcium polyphosphate fiber preparing method and the production equipment, the calcium polyphosphate raw material is heated through electrical heating, no waste gas is generated, the occupied area is small, the heat loss is less, mixed batch components are less in volatilization, adjusting and controlling are easy to conduct, thermal regulation is stable, the calcium polyphosphate fiber preparing method and the production equipment particularly meet the requirements of scientific researches and are suitable for being used under the conditions that the production capacity is small and the indoor or ventilating environment is poor.
