Abstract
Este trabajo se realizó con el objetivo de desarrollar una solución que permita llenarcontenedores ISO de 40’ con astillas de madera mediante un sistema de transporte neumáticode manera simple y efectiva. La utilización de contenedores ISO para el transporte yexportación de astillas representa una alternativa que incentive el ingreso de pequeñosproductores y la realización de transacciones en cantidades menores en un mercado relevantepara la economía nacional.Para estudiar el fenómeno de lanzamiento de partículas al interior del contenedor sediseñó e implemento un sistema a escala en las dependencias del Centro de Investigación parael Transporte de Materiales (CITRAM) del Departamento de Ingeniería Mecánica de laUniversidad Técnica Federico Santa María. Las cañerías, silo y la pared lateral del contenedorson de acrílico transparente lo que permite observar el comportamiento en el interior duranteel funcionamiento.Los ensayos realizados consisten en llenar el contenedor a través de una cañería instaladaen la puerta variando su velocidad, ángulo y altura respecto a la base. A cada configuraciónutilizada se le registra el porcentaje de llenado alcanzado y la trayectoria descrita. Para estosensayos se utilizó como material grits de maíz al ser uniforme y de fácil manipulación. Además,fue necesario caracterizar una muestra de astillas facilitadas por un productor nacional.Desde los datos obtenidos se seleccionó la configuración que entregó mejores resultadosy se determinó su configuración equivalente para ser utilizada en una solución a escala real.Utilizando esta equivalencia y la caracterización del material se diseñó un sistema neumáticomóvil capaz de llenar contenedores ISO con 15 [tons] de astillas de hasta 1” en una hora. Lascaracterísticas de este fueron contrastadas con alternativas disponibles en el mercado y serealizó un presupuesto en función de los costos directos.
This work was carried out with the objective of developing a solution that allows to filla 40’ ISO container with wood chips using a pneumatic transport system in a simple andeffective way. The use of ISO containers for transportation and export of wood chips representsan alternative that encourages the entry of small-scale producers and carry out small-scaletransactions in a relevant market to our national economy.To study the particles transport phenomenon inside of the container, a pneumatic systemat scale was designed and implemented in the Centro de Investigación para el Transporte deMateriales (CITRAM) facilities, dependent of the Mechanical Engineering Department of theUniversidad Técnica Federico Santa María. Pipes, silo and the side wall of the container aremade of transparent acrylic that allow to observe the behavior in the interior during operation.The tests carried out consist of filling the container through a pipe installed in the doormodifying its speed, angle and height with respect to the base. For each configuration used, thefilling percentage reached and the trajectory described are recorded. For these tests, corn gritswere used as material because it is uniform and easy to handle. In addition, it was necessary tocharacterize a sample of wood chips provided by a national producer.From the data obtained, the configuration that gave the best results was selected and itsequivalent configuration was determined to be used in a real scale solution. Using thisequivalence and the characterization of the material, a mobile pneumatic system was designedcapable of filling ISO containers with 15 [tons] of wood chips up to 1” in one hour. Thecharacteristics of this system were contrasted with alternatives available in the market and abudget was made based on direct costs.
