Simulation and Analysis on Compression Effect of Screw Conveyor in the Hopper on Seed Cotton
A discrete element simulation model is established with EDEM for compaction screw conveyor in the hopper. And simulation analysis on compression process of seed cotton during Working Process of compaction screw conveyor which provides guidance for structure design of compaction screw conveyor. Simulation results show that the compaction force of seed cotton produced by push function of compaction screw conveyor, and seed cotton compressions, adhesion, twisting force between particles are increased with the increase of the number of seed cotton. While the number of seed cotton no longer increases, seed cotton inter-atomic forces, smaller total compression force leveling off during the push stage. After the push stage, although seed cotton quantity does not increase, but under compaction stir the push of the compaction screw conveyor, seed cotton accumulation and extrusion in the front of hopper, the compression force of seed cotton increased significantly, so the total compression force of seed cotton rapidly increasing. Variable diameter compac-tion stir dragon institutions due to beat the dragon former after the small diameter, the accumulation in cotton seed cotton at the end of the box by the trail stirring dragons to stabilize the throughput of push forward, the front big diameter stirring the dragon will be a lot of seed cotton push compression, variable diameter compaction screw conveyor shows good effect on periodically push and compaction.
