| 中文摘要: |
| 针对目前对于大产量原粮振动清理筛的需求，结合TQLZ180×200型粮食振动清理筛，对大产量原粮振动清理筛进行结构改进。基于EDEM离散元分析软件对振动筛的筛分过程进行仿真模拟，分析振动筛工艺参数对筛分效果的影响，建立工艺参数和筛分效率关系曲线。结果表明，在振动筛的振动频率14 Hz、振幅3.5 mm、振动方向角35°、筛面倾角6°时，筛分效果最好。该研究为以后振动筛筛分效果分析和参数设定提供依据。 |

| Based on the current demand for large production raw grain vibration cleaning sieve, combining TQLZ180×200 type grain vibration cleaning sieve, the structure of large production raw grain vibration cleaning sieve was improved. EDEM discrete element analysis software was used to simulate the screening process of vibration sieve, and the influences of process parameters of vibration sieve on the screening effect were analyzed, then the relationship curves of process parameters and screening effect were established. It concluded that when the vibration frequency of vibration sieve was 14 Hz, amplitude was 3.5 mm, vibration direction angle was 35°and the sieve surface inclination was 6°,the screening effect was the best.So it provided the basis for the further study on screening effect analysis and parameter setting of vibration sieve. |
