Abstract

Heat Extrusion Unit for Ocean Cleaning of Plastic Debris by Melting for Volume Reduction

Abstract:

The proceeding information provides predicted results provided by mathematical modeling, functionality, and equations used to mechanically operate and design a system that will collectively process plastic ocean debris into elasticized solid lumps for means of transportation out of, and away from ocean waters.

The preliminary chosen design was a combination of a cylindrical compactor and heating induced elements. The final design, titled Heat Extrusion Unit; included a pipe of pre-determined length that houses the driving mechanism, an Auger to transport plastic material forward, an electric DC motor to rotate the Auger, a Hopper to chamber plastic debris for processing, Heating Bands to phase change plastic from solid-to-liquid, and an exit nozzle for processed plastic extrusion.

Conduction Heat Transfer and Heat Transfer Coefficient equations for a steel pipe were applied in conjunction with the Logarithmic Mean Temperature Difference to determine both the minimum working distance of heated pipe length needed, and the minimum power required to phase change plastic. The Mass Flow Rate equation was used to determine the motor’s torque and angular velocity for material transportation. Based on Auger geometry and mass flow rate variables, calculations for theoretical material processing rates were obtained.

This project began with three imposed upon requirements: mass constraint, power allotment, and corrosion resistant materials. Based on computer aided design, mathematical models, and material research, final results for the design’s mass, power usage, and chosen materials were 24.2kg, 678Wh, and 316L stainless steel respectively; all of which were within system requirements. Use of the Conduction Heat Transfer and Heat Transfer Coefficient equations aided in providing a numerical reference to identify a 6.21 x 10-1m of minimum pipe length working distance required to successfully process plastic material waste.

The final analysis determining feasibility of the design for practical operation has been achieved. With collected data from an assembled and functional Heat Extrusion Unit prototype, the interior and exterior, heating system, mechanical system, and electrical system have been mathematically modeled and demonstrated to show processing behavior and its intended use.
