Aluminium bar homogeneous be aluminium bar in homogeneous furnace after heating with insulation so that aluminium bar metallographic structure change is simultaneously uniform
Change, the transport of Jing chassis is reached after cooling chamber by the process of water-cooled quick refrigeration；With domestic and international aluminium bar, aluminium ingot homogeneous furnace
Extensive application, occur in that the various type of furnaces, requirement of the stove to blower fan is different, and some stoves need to use water-cooled,
Some stoves need it is air-cooled with cold wind wheel, some stoves need with pressure type it is air-cooled（Cold wind wheel+cooling blower）, some stoves use
Hollow shaft leads to cooling water, these can cooling bearing, but effect is different, cost is different, and the demand of market user is also different；Gesture
Selection must be brought different.
The reason for which part high temperature homogeneous furnace is because of scene and product itself can not fill water cooling system, can only use blower fan
Cooling, temperature is very high when the high temperature circulation blower fan on this kind of homogeneous furnace is used in stove, and in use blower fan will
Draught fan impeller is asked to be rotated both clockwise and counterclockwise crossing operation, fan transmission system does not have water cooling system again, so traditional
Such blower fan fixing bearing often because run it is overheated and with blower fan rotary shaft locking, cause blower fan to break down, to reducing wind
The service life of machine.
Utility model content
The purpose of this utility model there is provided a kind of high-temperature blower transmission group cooling device, overcome prior art not
Foot, arranges positioned at outer bearing carrier and inner pedestal centre position arrange in cooling fan, cooling fan two-way leading on the rotary shaft
