ET 493 Fall 2013 Advisor: Dr. Ma Instructor: Dr. Koutsougeras Southeaster Louisiana University Mechanical Engineering Undergraduate

 Design a conveyor belt system for the Sustainability Center

 Dusty environment  Exposure to heat from the boiler  Back burn  Pellet overflow/underflow  Danger of moving parts with high torque  Belt slip or misalignment

Conveyor 1 (Feeds boiler)  Research conveyor belt types and applications  Research safety requirements  Develop a general function layout using Visual Logics  Rough frame design  Optimal frame dimensions based on boiler/steam turbine intake  Strength analysis (force and moment balance, bending stress, etc.)  Motor selection  Design drive based on boiler/steam turbine intake rate  Determine necessary gear ratio (motor : drive – torque increase and speed reduction)  Belt selection based on pellet load  Placement of idlers on the frame (tension uptake)  Selection of alignment and heat sensors  Pellet regulation device- either before or after the conveyor  Add finer details to Visual Logic Conveyor 2 (from mill to storage)  ***repeat steps used for Conveyor 1 with the additions:  Elevation sensor for changing conveyor height with respect to storage pile height  Actuator selection

 Research conveyor types  Preliminary Visual Logic Layout  Safety Requirements  Rough Frame Design for conveyor 1 (feeding belt)  Belt research  Motor and Drive research  Acquired Boiler/Steam Turbine feed requirements
