Abstract
The utility model relates to a centrifugal fan for discharging high-temperature flue gas. The centrifugal fan comprises a fan shell, an impeller and an electric motor, wherein an output shaft of the electric motor is connected with the impeller inside the fan shell and is provided with a cooling wheel which is located between the fan shell and the electric motor and is made of an aluminum material; and a heat-absorption sheath is arranged outside the output shaft of the electric motor, is located between the impeller and the cooling wheel and is made of an aluminum material. According to the centrifugal fan for discharging the high-temperature flue gas provided by the utility model, while heat of the high-temperature flue gas is conducted by the output shaft of the electric motor, the heat can be carried away in time by the cooling wheel, and then the heat is discharged as the cooling wheel is driven by the output shaft of the electric motor to rotate, so that the heat of the high-temperature flue gas is uneasy to be conducted to the interior of the electric motor, the electric motor is prevented from being damaged due to a high temperature, and an electric wire of the electric motor is prevented from being burned due to short circuit as the temperature is too high, thereby avoiding potential safety hazards.
Description
Technical field
The utility model relates to a kind of centrifugal blower, relates 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, so that shorten the working life of centrifugal blower.Reason is: the heat of high-temperature flue gas can be transmitted to motor internal by the output shaft of motor, causes motor to damage because of excess Temperature, and the electric wire of motor also can burn because of the excess Temperature short circuit, also might cause potential safety hazard.
The model utility content
The utility model purpose is the difficult centrifugal blower that is transmitted to the dispatch high-temperature flue gas of motor internal by the output shaft of motor of heat that a kind of high-temperature flue gas is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of centrifugal blower of dispatch high-temperature flue gas, comprise Blower Housing, impeller and motor, the output shaft of described motor links to each other with impeller in the Blower Housing, and the output shaft of described motor is provided with the heat radiation wind wheel; Described radiation air wheel is positioned between Blower Housing and motor; Described heat radiation wind wheel is made by aluminium material.
Preferably, the output shaft of described motor is provided with the heat absorption sheath outward; Described heat absorption sheath is positioned between impeller and heat radiation wind wheel; Described heat absorption sheath is made by aluminium material.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
The centrifugal blower of dispatch high-temperature flue gas of the present utility model, because the output shaft of motor is provided with the heat radiation wind wheel, the radiation air wheel is positioned between Blower Housing and motor, the heat radiation wind wheel is made by aluminium material, 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, then the output shaft by motor drives the rotation of heat radiation wind wheel with dissipation of heat, so that the heat of high-temperature flue gas is difficult for being transmitted to motor internal, avoided motor to damage because of excess Temperature, also avoided the electric wire of motor to burn because of the excess Temperature short circuit simultaneously, thereby 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 made by aluminium material, when the heat that wheel rotation produces passes through the output shaft conduction of motor, can be siphoned away by the heat absorption sheath and conduct to the heat radiation wind wheel, be rotated dissipation of heat by the heat radiation wind wheel, avoid heat that wheel rotation produces to be transmitted to motor internal by the output shaft of motor, increased the stability that centrifugal blower uses.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of the centrifugal blower of dispatch high-temperature flue gas of the present utility model;
Wherein: 1, Blower Housing; 2, impeller; 3, motor; 4, output shaft; 5, heat radiation wind wheel; 6, heat absorption sheath.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
The centrifugal blower of described in the utility model a kind of dispatch high-temperature flue gas as shown in Figure 1, comprise Blower Housing 1, impeller 2 and motor 3, impeller 2 in the output shaft 4 of described motor 3 and the Blower Housing 1 links to each other, and the output shaft 4 of described motor 3 is provided with the wind wheel 5 that dispels the heat; Described heat radiation wind wheel 5 is positioned at 3 in Blower Housing 1 and motor; Described heat radiation wind wheel 5 is made by aluminium material; The output shaft 4 outer heat absorption sheaths 6 that are provided with of described motor 3; Described heat absorption sheath 6 is positioned at impeller 2 and 5 of wind wheels of heat radiation; Described heat absorption sheath 6 is made by aluminium material.In the centrifugal blower using process of dispatch high-temperature flue gas, when the heat of high-temperature flue gas passes through output shaft 4 conduction of motor 3, because heat radiation wind wheel 5 is made by aluminium material, the thermal conductivity of aluminium material is good, heat radiation wind wheel 5 can in time be taken away heat, then the output shaft 4 by motor 3 drives 5 rotations of heat radiation wind wheel with dissipation of heat, so that the heat of high-temperature flue gas is difficult for being transmitted to motor 3 inside, avoided motor 3 to damage because of excess Temperature, simultaneously also avoid the electric wire of motor 3 to burn because of the excess Temperature short circuit, thereby 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 to heat radiation wind wheel 5 by heat absorption sheath 6, rotated dissipation of heat by heat radiation wind wheel 5, the heat of having avoided impeller 2 to rotate producing is transmitted to motor 3 inside by the output shaft 4 of motor 3, has increased the centrifugal blower stability in use of dispatch high-temperature flue gas.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
