Automação e melhoria do sistema de filtragem de água de uma máquina de lavar bacias

Abstract

This paper presents the design and implementation of an automation on a basins washing machine, to decrease the power consumption, allowing increased amounts of basins cleaned per hour, reduce the number of machine breakdowns and improving its water filtration system. In the automation process we used a Siemens PLC LOGO 12/24RC where the program triggers the treadmill and the water bombs, when a box activate the sensor, thus the main loads are turned on only when boxes are present inside the machine. To increase the amount of washed basins was installed a frequency inverter that drives the motor of the treadmill, thus increasing the frequency increases the treadmill speed is increased and consequently the capacity to wash the basins. To improve water filtration system was designed, assembled and installed two filter screens on the sides of the machine to facilitate the removal of larger pieces of dirt. With automation was possible to save approximately 50 kW / h per day, after installing the inverter was possible to wash more basins in less time without losing the quality of the wash. By improving the filtration system with the new project, it was possible to reduce the cost and the time maintenance machine, make easier cleaning and generating less risk of contamination, thereby increasing the reliability of the machine.
