Study On Autonmatic Drug Adding System Of Floatation And Configuration Process Of Coking Middlings Regrinding Process

With the rapid development of electronic information technology and control theory, automatic control technology is playing an increasingly important role in many areas. Especially on coal flotation, automatic dosing control system can not be replaced. Automatic Reagent feeding system of coal slime can be achieved under the premise of ensuring concentrate ash,greatly improving the clean coal yield and reduce reagent consumption.The study of this thesis for coal in the coal preparation plant Babao the mill flotation dosing control system for accurate monitoring of dosing process, scientific management, application Kingview software configuration control system. The paper draw on engineering design thinking design of coal flotation automatic dosing system. First select the Babao coal preparation plant representative in coal grinding floating laboratory experiments and optimize the flotation reagent addition system, come to the best flotation reagent system; Then automatically flotation and hardware used in the drug control system elaborated from the host computer IPC next bit machine PLC, sensor, implementing agencies; Combination of hardware parameters based on experimental data of Pharmacy and the design of the PLC program; Kingview software the PC configuration design of the entire flotation automatic dosing system to achieve real-time monitoring of site conditions, and flotation parameters can be set through the configuration interface.The system uses the Mitsubishi FX2N-32MT programmable logic controller to do the lower computer, DH-CA-type precision solenoid valve do actuator. HC-1000non-contact type nuclear concentration meter and ZYLD type electromagnetic flowmeter is used to detecting floating coal slurry concentration and flow value, according to the concentration values and flow values calculate the stem coal slime to determine the amount of frother and collector add. The host computer uses the Advantech IPC-610H IPC,from which achieved configuration control. The main control interface include:the login screen, flotation automatic dosing main interface, real-time parameters interface, history parameter interface, real-time reporting interface, historical reporting interface.
