Abstract
The invention discloses a draught fan for conveying high-temperature smoke. The draught fan comprises a shell of the draught fan, an impeller and a motor, wherein an output shaft of the motor is connected with the impeller in the shell of the draught fan, a first cooling water cavity is arranged in a shell of the motor; a protecting bush of the output shaft of the motor is arranged between the shell of the draught fan and the shell of the motor; a second cooling water cavity is arranged in the protecting bush of the output shaft of the motor; and the first cooling water cavity and the second cooling cavity are communicated with each other. According to the draught fan for conveying high-temperature smoke, when the heat of the high-temperature smoke is transferred by the output shaft of the motor, the first cooling water cavity and the second cooling water cavity can absorb the heat of the high-temperature smoke, so that the heat of the high-temperature smoke can not be transferred in the motor easily, so that the damage of the motor due to overhigh temperature can be avoided, meanwhile, burnout of the motor due to too high temperature of an electric wire can be avoided, and further, the potential safety hazard is eliminated.

Background technique
Induced draught fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, can be used for carrying air and other non-hypergolic, harmless, to the free from corrosion flue gas of steel.But for some induced draught fans of carrying high-temperature flue gas; The heat of high-temperature flue gas can be transmitted to motor internal through the output shaft of motor; Cause motor Yin Wendu too high and damage, the electric wire of motor also can the too high short circuit of Yin Wendu and is burnt, and also might cause potential safety hazard.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: the heat that has proposed a kind of high-temperature flue gas is difficult for being transmitted to through the output shaft of motor the induced draught fan of the conveying high-temperature flue gas of motor internal.
Technical solution of the present invention is achieved in that a kind of induced draught fan of carrying high-temperature flue gas, comprises electric fan shell, impeller and motor, and the output shaft of said motor links to each other with impeller in the electric fan shell, is provided with first cooling water chamber in the said electric machine casing; Be provided with the motor output shaft sheath between said electric fan shell and electric machine casing; Be provided with second cooling water chamber in the said motor output shaft sheath; Said first cooling water chamber communicates with second cooling water chamber.
Preferably, be provided with temperature transducer and refrigerator in said first cooling water chamber.
Preferably, said electric machine casing is provided with first water intake and first water outlet outward; Be provided with stopper in said first water intake and first water outlet.
Preferably, said motor output shaft sheath is provided with second water intake and second water outlet outward; Be provided with stopper in said second water intake and second water outlet.
Preferably, said stopper is a rubber stopper.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The induced draught fan of conveying high-temperature flue gas of the present invention owing to be provided with first cooling water chamber in the electric machine casing, is provided with the motor output shaft sheath between electric fan shell and electric machine casing; Be provided with second cooling water chamber in the motor output shaft sheath; First cooling water chamber communicates with second cooling water chamber, and when the heat of high-temperature flue gas passed through the output shaft conduction of motor, first cooling water chamber and second cooling water chamber can absorb the heat of high-temperature flue gas; Make the heat of high-temperature flue gas be difficult for being transmitted to motor internal; Avoid motor Yin Wendu too high and damage, also avoided the too high short circuit of electric wire Yin Wendu of motor simultaneously and burn, thereby avoided the generation of potential safety hazard.
