Abstract
Aiming at the structure of the single air duct centrifugal fan in the existing full-feed grain combine harvester air sieve cleaning device, the flow channel model of the single air outlet single air duct centrifugal fan was established, and the mesh was partitioned using the MESHING software. And using CFD (Computational Fluid Dynamics) software to carry out three-dimensional numerical simulation of the internal flow field of the single-outlet single-channel centrifugal fan to determine the structure size of the fan. The improved internal flow field simulation results of the fan show that the airflow speed at the upper air outlet and the outer edge of the impeller of the single air outlet single air channel centrifugal fan is larger, and the air velocity attenuation distance is increased, which is beneficial to the airflow covering the entire screen surface; It is basically distributed in layers, and the lateral air flow at the air outlet is symmetrically distributed on the middle high side and low side, with obvious boundary effects. The influence of the fan speed, the distribution of the fan's internal flow field, the wind speed of the air outlet, and the air volume is analyzed: the wind speed and air volume of the air outlet gradually increase with the increase of the fan speed.
