Diseño y construcción de máquina Big Blaster lanza confeti con un alcance de tiro de hasta 12 metros impulsada por CO₂

Abstract

The present technical project starts from the need to reduce costs in the rent of special effects in the company M SHOW EVENTS starting with the machine launches confetti, being the main acquisition requested by clients immersed in the field of shows that require this type of artifacts. Because the existing machines on the market are not designed for large heights, various parameters such as draft angle, discharge time, carbon dioxide consumption, supply pressure to achieve the desired target were analyzed. The machine launches confetti type was built with materials available in the local market, the tank made of aluminum to prevent corrosion by climatic factors or unexpected leaks, the activation of carbon dioxide is done manually, integrated with output type valves thread for greater security and pressure gauge to verify the pressure to which the gas flows, Venturi ring with 8 output holes arranged evenly in the top of the same, possibility to regulate to 3 different shooting angles to be used in different scenarios, the wheels rotating front and rear with brake to give greater mobility and stability to the equipment, multicolored confetti paper of rectangular and light form to achieve a slower fall effect, the geometry of the storage hopper with inclination angle to take advantage of the suction all the contents of the container. With the results obtained it is shown that the best environment for launching is in a closed space because it avoids the presence of wind and other climatic factors, with shooting angle of 78 ° since it reaches a height of most of the confetti of 12 to 13 meters that is the main requirement of the machine, with a discharge time of 3 to 3,5 seconds and a consumption of carbon dioxide of 0.521 to 0,543 kg /s. However, it remains possible to regulate the gas outlet through the tank valve and the ball valve to be able to adjust to the height of the various scenarios where system rental services are required.
