Desenvolvimennto e construção de um prototipo de uma unidade de bombeamento de liquidos multiuso e movel para o laboratório piloto de química (Laqp)

Abstract

The pilot chemistry laboratory (LAPQ) during the COVID-19 pandemic provided an important service to UFPB by manufacturing household sanitizers intended for internal use and for donations to people with low economic power. Due to the high demand for products, more specifically liquid alcohol and alcohol gel, there was a need to work with large volumes, and this impacted working conditions, because as the laboratory was only prepared to work with the normal routine, there was no a mechanical means of transporting liquids, so employees had to transport the liquids in containers, and this caused ergonomic risk and loss problems. The ergonomic risk is associated with heavy lifting and poor posture when transporting liquids in containers and the loss problem was associated with the fact that small spills always occurred when filling the containers and also when the liquids from the containers were poured. The LAPQ has a production capacity between 1000L to 2000L per day, considering a two-shift workday, but to achieve such production capacity in an efficient and healthy way for employees, the need for a mechanical means of transporting liquids was observed. , so the idea was to use a hydraulic pump to solve the problem, but the laboratory has two production rooms and there were several different situations in which the liquid transport problem presented itself and the idea of installing a pumping station, as if normally, it wasn't very attractive as a pumping station is fixed and usually only serves a single purpose. Taking into account the problem and the limitations of the initial solution, the idea arose of a mobile and multipurpose device to meet the needs of the two production rooms and the different situations of liquid transport. The device was built without a previous written project, it was built only with scientific theoretical knowledge on the subject and intuition.
