- PublicaciónAcceso abiertoDiseño de una máquina trituradora de botellas PET (Tereftalato de Polietileno)(Universidad de Ibagué, 2022) Rubio Solano, Juan Sebastián; Ramírez Sandoval, Genisberto; Araque De Los Ríos, Oscar JavierEsta propuesta surge de una necesidad de la finca el Paraíso ubicada en la vereda cañada baja en el departamento del Tolima, municipio del Guamo, la cual tiene la exigencia de disminuir el volumen de los recipientes plásticos PET, debido que en el sector y lugares aledaños no cuentan con un servicio de recolección de basura, lo cual conlleva a que cada propietario de su respectiva parcela tenga que recolectar los desechos plásticos en sus hogares, gran parte de estos desechos son botellas plásticas PET, estas cuentan con un volumen aproximado entre 400 ml - 600 ml., ya que múltiples productos que se llegan a utilizar en la vida cotidiana, son fabricados a partir de este material polietileno tereftalato “PET”. Estos productos por lo general ocupan espacio por su geometría, generando un gran volumen de desperdicios y contaminación al medio ambiente, para contribuir con esta problemática se plantea el diseño de un prototipo de una máquina trituradora de botellas plásticos PET, con la finalidad de disminuir los recipientes a fragmentos de tamaño entre 2 cm^2 - 4 cm^2, en la finca el Paraíso y por lo tanto disminuir la contaminación ambiental, así como proporcionar un adecuado manejos con respecto al acopio de los desechos PET.
- PublicaciónRestringidoDiseño de máquina cortadora de bolsas para re-embalaje de devoluciones de arroz(Universidad de Ibagué., 2020) Patiño Olaya, Sergio; Araque de los Ríos, Oscar JavierThe purpose of this project is the design of a plastic bag-cutting machine for the repacking of rice returns by the rice mill S.A. For the design of the machine, the conditions and / or restrictions provided by the company presenting the study problem will be taken into account, as well as a design that complies with the efficient conditions of cutting and separating the plastic bags from the grain, so that it can be treated later. The design of the machine will be proposed taking into account all the knowledge applicable to mechanical design.
- PublicaciónAcceso abiertoDimensionamiento de una red experimental de 5 kw de salida(Universidad de Ibagué., 2019) Fajardo Gallo, Rodrigo Adolfo; Valverde Granja, AgustínThis research requires the dimensioning of an experimental network of 5 KW at the end, where five phases are established: execution of supported calculations, selection of inverter, the dimensioning of the electrical system, structural design and an economic proposal supported through RETScreen software in order to provide a solid research structure to the project. The final results of this project were a photovoltaic generator that consists of 22 solar panels with the Canadian Solar model CS6K-280P of 280 W each, these have a connection scheme of 11 solar panels in series and 2 branches in parallel which are connected with their respective maximum power tracker (MPPT) in the inverter brand ABB model PVI-6000-TL-OUTD of 6 KW, the network occupies a total area of 43.63 m2. Regarding the structural design, we worked with Hersic brand with aluminum supports for the fastening of the solar panels and to support the total weight of the modules and the aluminum structure a support made with structural steel profiles of 50x30x2mm was designed, that is conformed by 12 beams of 6 meters long distributed in 3 rows of 12 meters in double beam mode separated by 10 cm cuts of the same profile. On the other hand, 14 AWG conductors will be used for the DC section and 10 AWG for the AC section; As for the protections of the circuits to be used after the inverter, a thermomagnetic switch Legrand TX3 model 403610 curve C and a differential switch Schneider Electric model A9R71240 of sensitivity mA were selected, which will be located in the alternate voltage section ( VAC), in the DC section it is not necessary to use protection systems because the inverter comes with its own integrated disconnection system; In addition to the above, it was decided to work with a bidirectional Meter Schneider Electric IEM3119 model A9MEM3110 to account for the energy produced by the photovoltaic generator and the one that is being used from the network. Finally, through the use of RETScreen software it was possible to demonstrate that for this project, the project will have an IRR before taxes of 11.5% with a net present value (NPV) of $ 8,359,954, the annual savings in life cycle they correspond to $ 816,865 / year; It was also evidenced that when this photovoltaic generator is put into operation, a gross annual reduction of 3.3Tco2 will be made, also RETScreen software results show that the initial investment for the project will be recovered 8 years after the generator is running and after that period of time, the earnigs will double that investment on year 2025.
- PublicaciónAcceso abiertoFormulación de propuesta técnico-económica para la construcción de un equipo multifunción para la línea de producción de hojaldres de la empresa The Bakery(Universidad de Ibagué., 2019) Godoy Triana, Cristian Camilo; Araque de los Ríos, Oscar JavierThe purpose of this work is the elaboration of the design of a machine to improving production process of puff pastry business oriented “The bakery”, moreover of a approaches technical-economic to the construction of this; in order to carry out this, It had to: identify and characterize the process variables, to put up design alternatives and selection of the better proffer, to realize the corresponding calculations of the approach selected and that it complies with the engineering requirements and to budget the manufacturing costs, after of this it came to the conclusion that the best proffer is the N°2 due to its greater economy and better compliance with the requirements by customers, beside that this equipment can cost around $ 106.705.108 and which is very profitable at the time of acquiring it by the company since it can recover its investment in a year in addition to increasing its production and also its sales.
