单螺杆挤出机螺旋沟槽固体段产量的实验研究

在自制的测试仪上对单螺杆挤出机螺旋沟槽固体输送段的产量进行了实验研究,探讨了沟槽衬套、螺杆的结构参数,物料粒径大小及螺杆转速对单螺杆挤出机固体输送段产量的影响,同时将螺旋沟槽单螺杆挤出机与IKV挤出机固体输送段的产量进行了对比。实验研究表明：粒径越小,螺旋衬套沟槽越宽,固体输送段产量越高;螺杆螺距变化对挤出机固体输送段产量的影响很小;IKV直槽挤出机固体输送段的产量明显小于螺旋沟槽衬套挤出机的固体输送产量,而且随着转速的增加,趋势越明显。

Experimental Research on the Throughput of Solid Conveying Section in Helically Grooved Feed Single-screw Extruder

Experimental research on the throughput of solid conveying section in helically grooved feed single-screw extruder was carried out by the self-designed tester.Effects of main structural parameters of the groove and the screw,particle size of the material and screw speed on the throughput of solid conveying section were discussed.Besides,the throughput of solid conveying section in helically grooved feed single-screw extruder was compared with that in IKV extruder.The results show that the smaller particle size and the bigger groove width,the higher the throughput of solid conveying section;effect of screw pitch on the throughput of the extruder is not obvious;the throughput of IKV extruder is much lower than that of helically grooved feed single-screw extruder,and the higher screw speed,the more obvious the trend.
