CFD-Based Study on the Airflow Field in the Crushing Chamber of 9FF Square Bale Corn Stalk Pulverizer
During the steady operation of the 9FF square bale corn stalk pulverizer, the rapidly rotating spindle drives the hammers and impellers to form a complicated airflow field environment in the crushing chamber. The flow field characteristics in the crushing chamber can affect the motion law of stalks,...

| description | During the steady operation of the 9FF square bale corn stalk pulverizer, the rapidly rotating spindle drives the hammers and impellers to form a complicated airflow field environment in the crushing chamber. The flow field characteristics in the crushing chamber can affect the motion law of stalks, thus influencing the pulverizing effect of the hammer blades on stalks and the ejection of materials. Based on establishing the Computational Fluid Dynamics (CFD) calculation model of the crushing chamber in the 9FF square bale corn stalk pulverizer, in this paper, the effect of three groups of components, such as the hammer rack and blades, hammer rack and blades and the sieve, as well and the sieve and the impeller, on the distribution characteristics of airflow field in the crushing chamber. The simulation results show that the hammer piece group, screen, and impeller in the crushing room can effectively improve the crushing quality of materials, with the crushing efficiency and conveying efficiency at the highest speed of 3000 r/min. |
