基于数值模拟的片烟加料机参数优化设计
Parameter optimization of tobacco strip casing cylinder based on numerical simulation
摘要
Abstract
In order to promote the casing uniformity of tobacco strips and the utilization of casing,EDEM(Event Driven Execution Manager)numerical simulation technology was used to simulate the casing process in a cylinder.The orthogonal test was conducted to investigate the effects of spiral distribution angle and length of the lifting paddles and cylinder rotation speed on the residence time,dispersion and breakage degree of tobacco strips in the heating absorption section.Fluent software was used to simulate the movement trajectory of the casing at different injecting angles.The optimum parameter combination of the casing cylinder and the casing effect were determined.The results showed that:1)The spiral distribution angle of the lifting paddles and the cylinder rotation speed were the main factors affecting the residence time,dispersion and breakage degree of tobacco strips in the heating absorption section,and there were interactions between these factors.2)The optimum parameter combination determined was:the spiral distribution angle of the lifting paddle 25°,the length combination of the lifting paddle 400 mm and 600 mm,the cylinder rotation speed 10 r/min,and the casing injecting angle 55°.3)After the optimization of the parameters,the casing utilization rate reached 90.92%,which was increased by 5.05 percentage points;the casing uniformity reached 91.97%,which was increased by 4.36 percentage points;and the amount of the material adhering to the inner wall of the cylinder was reduced by 3.2 kg/batch.This technology helps improve the effects of tobacco casing and reduce the amount of material adhering to the inner wall of the cylinder.关键词
