Diseño y construcción de un prototipo de máquina trituradora para botellas plásticas PET reciclables con capacidad de 5kg/h

Abstract

This technical project is the construction of the different components of a prototype of a crushing machine for recyclable PET bottles with a capacity of 5kg / h, taking the parameters of the most common bottles found in recyclers, which is the three-liter PET bottle. Currently, PET bottles are used to pack a variety of liquids increasing the manufacture of containers generating a considerable amount of garbage, the containers having an adequate recycling process can be reused in various products helping to reduce the amount of garbage that accumulates packaging, causing environmental pollution that is one of the problems for the planet. Parameters were determined for the choice of the machine, the crushing capacity and the construction cost, the alternatives applied to build the machine are the following: hammer, roller, double shaft and one shaft, taking the alternative of double shaft that meets the aforementioned requirements. For the construction and sizing, the necessary force is taken to cut the PET material and the efforts to which the different components are subjected, which with the inventor software the different elements were analyzed, complying with the necessary safety factors and then selecting the right material for each of them. The profitability parameters of the technical project were analyzed giving a positive indicator for its construction, and then proceeded to carry out the tests of the machine giving a crushing capacity of 5kg / h with crushed pieces of approximately 15x10mm.
