两自由度往复式滚筒筛茶叶筛分模拟研究
Simulation Study on the Screening of the Reciprocating Roller Screen with Two Degrees of Freedom for Tea
摘要
Abstract
Taking Yongxi Huoqing tea as research object, the EDEM based on the discrete element method was used for simulation study the influence of the kinematic and structure parameters of reciprocating roller screen with two degrees of freedom on screening efficiency for tea leaves. The effects of roller inclination, reciprocating angle and reciprocating frequency on screening was analyzed when the roller was on reciprocating rotational movement. It was found that the ideal parameters of the roller were: 4-6°(inclination), 2-2.5 Hz (reciprocating frequency) and 60-75° (reciprocating angle). Furthermore, an X-direction excitation was added to the roller screen to study the effects of excitation frequency, amplitude and reciprocating angle on the screening process by orthogonal test. The simulation results showed that the ideal parameters of the roller screen were:8 Hz (excitation frequency), 8 mm (amplitude) and 70°(reciprocating angle) under screening mode with two degrees of Freedom.关键词
