Centrifugal fans use input mechanical energy to increase gas pressure and mechanically discharge gas. The development of centrifugal fans has gone through a long period and is now widely used in various industries, such as cooling towers, ventilation in buildings, dust removal and cooling, ventilation and induced draft in boilers and industrial furnaces, as well as cooling and ventilation devices in household appliances. It is worth mentioning that centrifugal fans also play a significant role in agriculture, such as in the drying and sorting of grains.
Now, let's introduce a centrifugal fan device for cleaning and sorting grains, which involves the manufacturing of a wind turbine. It mainly consists of a motor and a centrifugal fan, fixed on the main frame. On the main frame, there is a fan bracket, and the axial pivot of the centrifugal fan's casing is dynamically matched with the bracket on the fan frame. The drive wheel of the motor on the main frame is mechanically connected to the passive wheel of the centrifugal fan. At the back of the centrifugal fan's casing, there is an arc-shaped adjustable sliding groove, fixed to the fan bracket through fastening bolts.

This new type of grain cleaning centrifugal fan device is very reasonable in overall structural design, and it achieves the adjustment of the fan's speed, thereby changing the wind speed. The fan also adopts an adjustable fan bracket, which not only provides support but also allows adjustments of the fan's up, down, forward, and backward positions, as well as changing the fan's angle.
Furthermore, the fan bracket is separate from the main frame, and the bracket is equipped with casters, making it very convenient to adjust the distance between the fan and the sieve. The bracket also has a simple hydraulic adjustment device, enabling adjustments in the height and angle of the fan in a broad direction.
The development and use of this centrifugal fan have greatly assisted people in better selecting grains, meeting diverse needs, and improving work efficiency. It can be said to be a win-win situation, and with the help of centrifugal fans, cleaning and sorting grains are no longer challenging tasks.
