| 中文摘要: |
| 分析橡胶膨胀干燥机设备故障原因，并提出相应对策。通过采取筒体内均匀分布沟槽、进料段螺套螺距与直径比由0.64增大到0.96、螺杆轴与螺套由单键连接改为渐开线花键连接、取消螺套原缺口并使螺套起始点与终止点的方位错开及改进进料斗下部滤网结构等措施，在不增大电机功率、不改变螺杆转速、采用1.0 MPa饱和蒸汽压的前提下，可减少蒸汽用量，延长设备的运转周期，保证产品质量，降低能耗，提高单机生产能力。 |
| 英文摘要: |
| The equipment failure of rubber expansion dryer was analyzed，and the corresponding countermeasures were put forward.By means of evenly distributed grooves in the barrel，increasing the sleeve pitch to diameter ratio from 0.64 to 0.96 in the feeding section，changing the single key connection between the screw shaft and the screw sleeve to involute spline connection，canceling the original gap of the screw sleeve and staggering the orientation of the starting point and the end point of the screw sleeve，and improving the structure of the filter screen at the lower part of the hopper，under the condition that the motor power was not increased，the screw speed was not changed，and the saturated steam pressure was 1.0 MPa，the steam consumption could be reduced，the operation cycle of the equipment was prolonged，the product quality was guaranteed，the energy consumption was reduced，and the production capacity of single machine was improved. |
