Abstract
The invention discloses a centrifugal fan for exhausting high-temperature flue gas. The centrifugal fan comprises a fan housing, an impeller and a motor, wherein an output shaft of the motor is connected with the impeller in the fan housing and is provided with a heat dissipation wind wheel; the heat dissipation wind wheel is located between the fan housing and the motor and is made of aluminum material; and a heat adsorption sheath is arranged outside the output shaft of the motor, is located between the impeller and the heat dissipation wind wheel, and is made of aluminum material. According to the centrifugal fan for exhausting high-temperature flue gas disclosed by the invention, heat of the high-temperature flue gas is conducted through the output shaft of the motor, the heat dissipation wind wheel can take away heat in time, then the output shaft of the motor drives the heat dissipation wind wheel to rotate to dissipate heat so that the heat of the high-temperature flue gas is difficult to conduct into the motor, thereby avoiding the damage of the motor due to overhigh temperature, simultaneously wires of the motor are prevented from being burnt down due to short circuit caused by overhigh temperature, and therefore potential safety hazards are avoided.
Description
Technical field
The present invention relates to a kind of centrifugal blower, relate in particular to a kind of centrifugal blower of dispatch high-temperature flue gas.
Background technique
Centrifugal blower is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and is extensive in sector applications such as power plant, mines.But for some centrifugal blowers, because of work under bad environment, the flue-gas temperature of dispatch is higher, makes shorten the working life of centrifugal blower.Reason is: the heat of high-temperature flue gas can be transmitted to motor internal through the output shaft of motor, causes motor Yin Wendu too high and damage, and the electric wire of motor also can the too high short circuit of Yin Wendu and 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 centrifugal blower of the dispatch high-temperature flue gas of motor internal.
Technical solution of the present invention is achieved in that a kind of centrifugal blower of dispatch high-temperature flue gas, comprises Blower Housing, impeller and motor, and the output shaft of said motor links to each other with impeller in the Blower Housing, and the output shaft of said motor is provided with the heat radiation wind wheel; Said heat radiation wind wheel is positioned between Blower Housing and motor; Said heat radiation wind wheel is processed by aluminium material.
Preferably, the output shaft of said motor is provided with the heat absorption sheath outward; Said heat absorption sheath is positioned between impeller and heat radiation wind wheel; Said heat absorption sheath is processed by aluminium material.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The centrifugal blower of dispatch high-temperature flue gas of the present invention, because the output shaft of motor is provided with the heat radiation wind wheel, the heat radiation wind wheel is positioned between Blower Housing and motor; The heat radiation wind wheel is processed by aluminium material, and the thermal conductivity of aluminium material is good, when the heat of high-temperature flue gas passes through the output shaft conduction of motor; The heat radiation wind wheel can in time be taken away heat; Output shaft through motor drives the heat radiation wind wheel and rotates heat is distributed then, makes the heat of high-temperature flue gas be difficult for being transmitted to motor internal, has avoided motor Yin Wendu too high and damage; While has also been avoided the too high short circuit of electric wire Yin Wendu of motor and has burnt, thereby has avoided the generation of potential safety hazard; Simultaneously, because the output shaft of motor is provided with the heat absorption sheath outward, the heat absorption sheath is positioned between impeller and heat radiation wind wheel; The heat absorption sheath is processed by aluminium material; When the heat that wheel rotation produces passes through the output shaft conduction of motor, can be siphoned away to conduct by the heat absorption sheath and give the heat radiation wind wheel, rotate by the heat radiation wind wheel heat is distributed; Avoided heat that wheel rotation produces to be transmitted to motor internal, increased the stability that centrifugal blower uses through the output shaft of motor.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of the centrifugal blower of dispatch high-temperature flue gas of the present invention;
Wherein: 1, Blower Housing; 2, impeller; 3, motor; 4, output shaft; 5, heat radiation wind wheel; 6, heat absorption sheath.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
The centrifugal blower of the of the present invention a kind of dispatch high-temperature flue gas shown in accompanying drawing 1 comprises Blower Housing 1, impeller 2 and motor 3, and the output shaft 4 of said motor 3 links to each other with Blower Housing 1 interior impeller 2, and the output shaft 4 of said motor 3 is provided with heat radiation wind wheel 5; Said heat radiation wind wheel 5 is positioned at 3 in Blower Housing 1 and motor; Said heat radiation wind wheel 5 is processed by aluminium material; The output shaft 4 outer heat absorption sheaths 6 that are provided with of said motor 3; Said heat absorption sheath 6 is positioned at impeller 2 and 5 of wind wheels of heat radiation; Said heat absorption sheath 6 is processed by aluminium material.In the centrifugal blower using process of dispatch high-temperature flue gas; During output shaft 4 conduction of the heat of high-temperature flue gas through motor 3, because heat radiation wind wheel 5 is processed by aluminium material, the thermal conductivity of aluminium material is good; Heat radiation wind wheel 5 can in time be taken away heat; Through output shaft 4 drive heat radiation wind wheels 5 rotations of motor 3 heat is distributed then, make the heat of high-temperature flue gas be difficult for being transmitted to motor 3 inside, avoided motor 3 to damage because of temperature is too high; While has also been avoided the too high short circuit of electric wire Yin Wendu of motor 3 and has burnt, thereby has avoided the generation of potential safety hazard; Simultaneously; When the heat that impeller 2 rotations produce passes through output shaft 4 conduction of motor 3; Can be siphoned away conduction by heat absorption sheath 6 and give heat radiation wind wheel 5; Rotated by heat radiation wind wheel 5 heat is distributed, the heat of having avoided impeller 2 to rotate producing is transmitted to motor 3 inside through the output shaft 4 of motor 3, has increased the centrifugal blower stability in use of dispatch high-temperature flue gas.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
