Continuous Weighing Technology with Increased Energy Efficiency of Bulk Materials with Various Physical and Mechanical Properties

The article proposes a new method of continuous weighing-dispenser flow meter, which differs from the known ones in that another point has been additionally introduced to control the flow of bulk material, which reduces the measurement error of the flow velocity. Based on the uneven distribution of the material on the belt, an algorithm for weighing bulk materials entering the conveyor belt, and an intelligent algorithm for controlling the speed of the conveyor belt to improve metering accuracy and reduce energy consumption, have been developed. For the proposed method of dosing, the nature of the influence of the speed of the conveyor belt on the measurement error of the flow at variable flow and power consumption of the process line is determined, the range of permissible speeds is determined. A mathematical model of the production line has been developed, which takes into account the change in the accuracy of measuring the flow rate of bulk material and energy consumption at different speeds of the conveyor belt. A laboratory diagram of a linear flow meter with an intelligent electric drive control system was developed and investigated, which provides increased measurement accuracy and energy efficiency of the installation.
