Construction
The oven will house the metal conveyor plates that is secured to the already existing chain conveyor system. There is an electric timer connected to the ovens conveyor movement controls that will have the conveyor stop moving to allow the pyrolysis process to take place. There is also be a ramp system that allows for easy insertion and retrieval of carbon fiber pieces, as the shroud makes it more difficult.
​
All of the parts required in thedesign can be easily sourced or are already sourced. The conveyor system will be made from aluminum sheet metal which CWU has already sourced, along with the wire that will be used to secure the conveyor system. The electrical parts are going to be simple resistor setups to create an analog timer, and the resistors can either be sourced from CWU or easily acquired, as resistors are abundant and cheap. Finally, the funnel system to move the carbon fiber into and out of the system will be made from the already acquired aluminum.
​
Problems occurred when designing and building the ramp to allow for easy loading of material to the conveyor plates. The sheet metal originally designed for was causing the carbon fiber pieces to not slide and thus not reach the conveyor. This was probably due to too high of a friction force acting between the ramp and the carbon fiber. To solve this issue a part from the oven was used. In the original Avatoast oven assembly, there was a ramp tray that caught the toast from the back end and slid it closer to the front to grab. This part was cut in half to utilize the curved side and was used as the ramp instead. The friction is lower on this ramp because the metal is coated with something that reduces the friction. This not only solved the problem of moving the pieces to the conveyor but also repurposes parts that were previously going to be thrown out.
​
The final assembly will include the oven with the metal conveyor plates secured via metal wire to the current chain system, the timer to control the on-board motor, the ramp system, and the shroud to hold the argon gas in the oven’s space. The argon will be pumped in through a rubber hose into the top of the shroud.
