High-temperature-resistant spiral conveyor

The utility model relates to a high-temperature-resistant spiral conveyor, which comprises a motor control system and a material conveying system. The high-temperature-resistant spiral conveyor further comprises a cooling and sealing system which is coaxially arranged between the material conveying system and the motor control system, wherein the cooling and sealing system comprises a solid insulation sealing device, and the solid insulation sealing device is communicated with the material conveying system through a spiral shaft interface; and a solid material inlet is formed in the upper part of the solid insulation sealing device, a material outlet is formed in the lower part of the solid insulation sealing device, and solid particles passing through the solid insulation sealing device are used for heat insulation and temperature reduction. The cooling and sealing system further comprises a gas cooling device and a circulating liquid cooling device which are coaxially arranged between the solid insulation sealing device and the motor control system, wherein the gas cooling device and the circulating liquid cooling device are of a cylindrical cavity, and a shell body of the cylindrical cavity is of a hollow sandwich structure. The high-temperature-resistant spiral conveyor has the advantages of simple structure, capability of conveying high-temperature materials, and the like.
