The model utility content
Technical problem to be solved in the utility model is: will provide a kind of does not need water flowing and can effectively prolong the bearing high-temperature blower in working life.
For addressing the above problem, the technical solution adopted in the utility model is: high-temperature blower, comprise: rack-mount motor, support is fixed on the installation panel inboard, also be provided with fitting seat on the installation panel inner side surface, motor is by the drive unit drive main spindle, main shaft is bearing in the fitting seat by pair of bearings, the other end of main shaft passes installation panel and at this end impeller is installed, intake grill is positioned at the impeller outside and is fixedly mounted on the installation panel by sleeve, also is provided with thermal-protective coating in the installation panel outside; Also be provided with strong cold wind leaf on the main shaft of fitting seat being positioned at, on the sidewall of fitting seat, offer vent hole.
A bearing in the described pair of bearings is arranged on fitting seat inside, its concrete mounting structure is: be fixed with circular supporting plate on the fitting seat inwall, this bearing is installed on the supporting plate by several supporting sleeves and bolt, leaves the space between bearing and the supporting plate;
Between installation panel and main shaft, be provided with seal ring;
On the inwall at described sleeve two ends, be set with cushion block, be bolted on the described cushion block and threaded end outside, intake grill and installation panel are fixed on the two ends of sleeve respectively by locking nut, cotter pin is arranged in the groove of locking nut, and described bolt is passed in described cotter pin;
Described thermal-protective coating is made of multilayer water-soluble fibre blanket.
The utility model has the advantages that: the thermal-protective coating that employing multilayer water-soluble fibre blanket constitutes effectively trap heat transmits in fitting seat by installation panel, and come fast the heat that enters in the fitting seat to be discharged by the distance that adopts strong cold wind leaf and increase between bearing and the supporting plate, prolong the working life of bearing and need not lead to cooling water.
