Diseño de un sistema eléctrico de control de velocidad de una banda recolectora de úrea.

Abstract

One of the lines of Agrotechna S.A. is the production and sale of fertilizers, since it has been detected that in the úrea production process there are shortcomings that affect the company economically, generate environmental pollution and affect the health of workers, this research seeks to solve the causes of this problem, and whose objective is “to study the control of the speed of the urea collection band from the mixer to avoid losses of product that falls to the floor. First, the theoretical-technical parameters related to the operation of a collection band similar to that used in the company are determined; then the problems have been identified in the production line and that generate product waste, establishing that the main one is the poor control of the transportation speed of the band; finally they are proposed as technical solutions to the observed problems, implement a control system that allows moving the motor of the band in a controlled manner, composed of a frequency variator, a height-tosolids sensor that regulates the motor by means of a model of closed loop; In addition, other secondary actions are proposed to improve the efficiency of the production process. The study to determine a viable and acceptable solution within a trechnicale conomic context, has been oriented as an analytical, documentary and field investigation.
