摘要/Abstract

摘要： 为探究水平双螺旋输送机在输送黏性物料时的输送效率和黏性颗粒经输送过程后的完整性,并寻求输送机最佳结构参数,在保证填充率为30 %的前提下,通过改变输送机的螺旋直径、螺距直径比及交叠面积比这3种参数,在离散元软件EDEM中模拟仿真,研究结构参数与颗粒平均轴向速度、颗粒破碎率之间的相应变化关系,并选取较优参数组合,评估各参数对颗粒平均轴向速度和颗粒破碎率的影响显著性。研究表明,增大螺旋直径有利于提高双螺旋输送机在运输黏性物料时的输送效率,并且颗粒破碎率变化幅度不超过5 %,螺距直径比和交叠面积比不宜过大;最优结构参数组合是螺旋直径为200 mm、螺距直径比为1及交叠面积比为0,三者均对颗粒平均轴向速度有显著性影响,其中交叠面积比对颗粒破碎率影响较为显著,其余两者影响不明显。

Abstract: In order to study the conveying efficiency of the horizontal double screw conveyer when conveying the viscous material and the integrity of the viscous particles after the conveying process,and to seek the optimum structural parameters of the conveyer,on the premise of ensuring the filling rate of 30 %,by changing the three parameters of screw diameter,screw pitch diameter ratio and overlap area ratio of the conveyor,the simulation was carried out in the discrete element software EDEM,the relationship between the structural parameters and the average axial velocity of particles and the particle breakage rate was studied and the better parameter combination was selected. The effects of the parameters on the average axial velocity of particles and particle breakage rate were evaluated. The results show that increasing the screw diameter is beneficial for enhancing the conveying efficiency of the double screw conveyor when transporting viscous materials,and the change range of particle breakage rote is less than 5 %,and the ratio of screw pitch diameter and overlap area should not be too large. The optimum structure parameters are:screw diameter 200 mm, screw pitch diameter ratio 1,overlap area ratio 0. The three parameters have significant effects on the average axial velocity of particles,the overlap area ratio has a significant effect on particle breakage rote,while the other two have no significant effect.

Key words: double screw conveyor, screw diameter, screw pitch diameter ratio, overlap area ratio, average axial velocity of particles, particle breakage rate
