| 中文摘要: |
| 利用有限元分析软件Fluent分析制备再生橡胶的单螺杆挤出机喂料段螺槽深度（H）、螺杆导程（S）和螺棱宽度（e）对物料输送效率的影响。通过正交试验和单因素试验，优化设计出单螺杆挤出机喂料段的H为27 mm，S为170 mm，e为9.0 mm，优化设计后的单螺杆挤出机喂料段物料流动速度加快，输送效率提高。该研究结果可以用来指导制备再生橡胶的单螺杆挤出机喂料段设计。 |
| 英文摘要: |
| The effects of the screw groove depth（H），screw lead（S） and screw edge width（e） of
the feeding section in the single screw extruder for preparing reclaimed rubber on the material conveying
efficiency were analyzed by using finite element analysis software Fluent. Through orthogonal test and single
factor test，the H，S and e of the feeding section were optimized to 27 mm，170 mm and 9. 0 mm，respectively.
The optimized single screw extruder could speed up the material flow of the feeding section and improve the
conveying efficiency. The research results could be used to guide the design of the feeding section of single
screw extruder for preparing reclaimed rubber. |
