| 中文摘要: |
| 实验研究了粒径分布范围在1.3mm~3.0mm之间的分子筛在振动装填过程中，各种振动参数包括振动频率、振动幅度和振动时间等对分子筛装填密度的影响，并得到最佳的振动装填工艺参数。结果表明，随着频率和振幅增大，装填密度先增加后减小，存在最佳值。在本文实验条件下，频率和振幅的最佳值分别为55Hz和0.6mm。装填密度随振动时间的增大逐渐增加并趋于定值。这些可以作为确定该粒径范围内分子筛振动装填工艺参数的基础。 |

| Vibration loading progress of molecular seive whose granularity distributed from 1.3mm to 3.0mm was experimentally studied, and various factors of the process such as the vibration frequency, the vibration amplitude, the influence of vibration loading time on the molecular sieve packing density were investigated. Results show that the packing density firstly increases with the frequency increasing and achieves a peak value, then reduces. So the frequency has a optimal value. Relationship between amplitude and packing density is the same as the effect of the frequency on packing density. In the conditions of this paper, the optimal value of frequency is 55Hz, and that of amplitude is \{0.6mm\}. With the increase of the loading time, the packing density gradually increases to a certain value. These could serve as the basis in determining the technological parameters of the vibration loading progress of the molecular seive at this particle size scale. |
