Slag Grinding Production Line Plc Control System Research And Design

Slag grinding paper focuses on the production line PLC control system concept, establishment of common functional blocks and control system stability. In the consolidated results of previous studies based on exploring a more optimized slag grinding production line PLC control system. The investment of the economy, the stability of the system has good practical value and theoretical significance.First, according to slag grinding production line equipment, structural features and technology, introducing Tai MODBUS PLUS network and field bus technology, to determine the basic requirements of the control system, the main function, I / O modules, slag grinding and slag production control principle and strategies.Schneider Modicon Quantum series PLC combines the characteristics of slag grinding completed production line equipment control system hardware design and the main program module, pressure modules, the module temperature, slag production of PI regulator, regulating valve opening control module and the man-machine interactive interface software design. PI regulator used to adjust the slag production: the introduction of PID control algorithm, the use of Concept XL V2.6PLC programming software, to achieve production output of slag weighing of the closed-loop control, improved dosing flexibility and control of intelligence; regulator valve types opening to control the mill powder outlet temperature, moisture content of finished products to ensure that slag; quantitative control the speed of the powder, mineral powder required to regulate the quality of parameters; tank under pressure slag grinding mill production line of the actual situation automatically adjust the mill cylinder pressure to ensure stable operation of the mill; achieved through human-computer interface running on the production line monitoring and temperature, pressure, valve settings, through the PLC, the drive automatically adjusts the speed of the powder, enhanced the production of safety and productivity. These measures are to ensure that the slag grinding the normal operation of production line equipment.Finally, the design of the slag grinding production line PLC control system is commissioning to verify the feasibility of the control system design and reasonable.
