Projeto de um triturador de polímeros para a UTFPR Campus Guarapuava

Abstract

This work aims to present the design, detailed parts specification, and numerical simulation of the blades for a benchtop plastic shredder. The increasing demand for sustainable solutions in plastic waste treatment has led to the conception of this device, which aims to reduce the volume of discarded plastics and lower operation costs for the 3D printing laboratory at UTFPR Guarapuava campus through an efficient and accessible process. The research encompassed several stages. Initially, a literature review was conducted on existing plastic shredding methods, aiming to identify best practices and the main challen ges in this field. Based on this information, a conceptual design for the benchtop plastic shredder was developed. Subsequently, technical drawings and detailed specifications of the parts comprising the shredder were elaborated. Each component was carefully designed, considering factors such as mechanical strength, durability, and ease of fabrication. 3D modeling software was utilized to visualize the parts and generate the necessary files for fabrication.Moreover, a numerical simulation of the shredder blades was performed using structural analysis software. Representative loads and boundary conditions for the plastic shredding process were applied. The obtained results allowed for the assessment of blade strength and identification of potential areas for improvement. A parts list required for the construction of the benchtop plastic shredder was compiled, considering available materials in the market and feasible costs. Suppliers for each component were identified, facilitating the material acquisition process. In conclusion, the development of a benchtop plastic shredder is viable and offers a practical and accessible solution for plastic waste processing. The detailed design of the parts and numerical simulation of the blades provide technical foundations for the construction and optimization of the device. It is expected that this work can contribute to the dissemination of sustainable plastic treatment technologies and facilitate the construction process of the shredder for effective utilization on the campus.
