DOI : https://doi.org/10.35633/inmateh-69-60
In order to explore the conveying mechanism of kneaded corn stalk in the screw conveyor and improve the conveying performance of the screw conveyor, the study of the screw conveying process of kneaded corn stalk was carried out, and the simulation model of the screw conveying process of kneaded corn stalk was established by using the discrete element method. The results showed that: The pitch, feed amount and screw shaft speed have significant effects on the productivity and power of screw conveying, and there are significant interactions. The optimal parameters of the multi-factor simulation optimization test were 319.428mm pitch, feed amount of 71.062kg/min, screwshaft speed of 117.034r/min, corresponding productivity of 71.517kg/min and power of 769.84W. This study reveals the screw conveying mechanism of kneaded corn stover, verifies the feasibility of using discrete element simulation to analyze the conveying process of kneaded corn stover, and provides a theoretical basis for improving and optimizing the screw conveying device.
