Abstract
The utility model relates to an induced draft fan for conveying high-temperature flue gas, which comprises an induced draft fan shell, an impeller and a motor; an output shaft of the motor is connected with the impeller in the induced draft fan shell; a first cooling water cavity is formed in a motor shell; a motor output shaft sheath is arranged between the induced draft fan shell and the motor shell; a second cooling water cavity is formed in the motor output shaft sheath; and the first cooling water cavity is communicated with the second cooling water cavity. The induced draft fan for conveying the high-temperature flue gas has the beneficial effect that when the heat of the high-temperature flue gas is conducted by the output shaft of the motor, the first cooling water cavity and the second cooling water cavity can adsorb the heat of the high-temperature flue gas, so that the heat of the high-temperature flue gas is not easy to conduct into the motor, the damage of the motor due to overhigih temperature is avoided, and meanwhile, an electric wire of the motor is prevented from being short-circuited due to overhigh temperate to be burnt, thereby avoiding the occurrence of potential safety hazards.
