Simulation and optimization of key component structure of vertical spiral extrusion filling equipment for polymer-based high-viscous slurry
To solve the problem of human-machine interaction and manual operation in the charging process of polymer-based high-viscous slurry,a vertical spiral extrusion-charging process was adopted to obtain a continuous loading of ener-getic slurry.Based on analyzing the characteristics of the high viscous slurry,the screw configuration and barrel structure were simulated and optimized.The results indicated that pineapple head mixing element not only improved the particle-mixing effects but also caused hidden dangers such as a rise in high shear and high temperature.Therefore,this mixing ele-ment is not suitable for the stable and safe transportation of a high-sensitivity slurry.Meanwhile,the blocking effect of the flow channel was significantly reduced by setting the size of the die and the cone angle of the barrel to be Φ30 mm and 1 °,respectively.This could weaken the hidden dangers such as high pressure and high temperature to ensure process safety.
