Diseño e implementación de un sistema automatizado para fabricación de la pólvora por vía húmeda, en la empresa artesanal pirotécnica Vizuete.

Abstract

In the present research an automated system for the production of gunpowder is developed, applying the method of manufacture by wet way, in order to protect the integrity of the craftsman during the manufacture without compromising the quality of the product required for its work. The design of the system is adapted according to the needs of the powder processing method to ensure its efficiency, considering the least amount of product loss, a kettle with heating system and a jacket for the temperature reduction were implemented, integrating pneumatic systems to move the devices efficiently. A programmable logic controller (PIC) called Controllino Maxi Automation is implemented, based on the Arduino Platform, which allows the versatility of the sensors used in the investigation, adding a human machine interface (HMI) where the stages of the process are visualized total control of the system through the protocol Ethernet TCP/IP. As a result of the tests. It is concluded that the method and the automation of the system guarantee the security of the operator, through the use of the Mosler risk analysis technique, it was verified that the system has a low risk during its production, the system guarantees the speed of combustion in the required powder. According to the criterion of the craftsman and the tests carried out, the combustion rate for high quality powder obtained an average of 10, and for low quality gunpowder a rating of 8. Also, the losses of the product were optimized until a loss of 10% of total product and optimizing production time by 65%. It is recommended that the operator proceed with extreme care and with the necessary operating conditions during use, in addition to using the necessary protections during all stages of the process.
