Description
Technical field
The utility model relates to ore grinding control technology field, ore dressing plant, particularly a kind of ore dressing plant ore grinding intelligence step control equipment.
Background technology
Grinding process mainly is with the particle of ore through milled processed beading degree level, offers ore dressing, prepares to meet the raw material of ore dressing production granularity for ore dressing, makes the preparatory process of ore-dressing technique.After the grinding of ore process physics, the classification, particle is varied down to certain degree, and just can reach the monomer dissociation of ore or be similar to monomer dissociation, in theory, thin more metal recovery and the metal enrichment that helps ore-dressing technique more of grinding particle size.Therefore grinding process is to influence the key link that ore dressing is produced, and it is directly restricting dressing product quality and metal recovery rate.But grinding particle size is thin more, and its energy consumption is big more, and the grinding process energy consumption accounts for 40%～60% of the whole ore dressing process in ore dressing plant, therefore, also will cut down the consumption of energy as much as possible when guaranteeing grinding particle size, saves material.In order to improve grinding efficiency, to save energy and reduce the cost, improve the economic benefit of concentrate grade and the recovery and raising ore dressing field, realize that the automatic control of grinding process has crucial economic implications.
As shown in Figure 1, grinding process generally is divided into two sections grindings and classification.First section ore grinding generally adopts autogenous grinding or Semi-Autogenous mode, mining factory is shipped relatively large ore tentatively grinds, iron ore slurry after the grinding carries out classification by one section cyclone, and its overflow flows to the next stage ore grinding, and its underflow turns back to first section autogenous tumbling mill and grinds again.Second section ore grinding adopts ball milling method, and the iron ore that first section autogenous tumbling mill ground continues to grind, and carries out classification once more by two sections cyclones then, and its overflow flows to mineral processing circuit, and its underflow turns back to second section bowl mill and grinds again.
Along with international iron ore price goes up significantly, the exploitation of China's iron ore and sort and highlight increasing economic worth and strategic value.And the quality of grind grading directly influences the height of the grade of ore dressing finished product, so the classification of grind grading intelligence has very important vital role.Yet what partly taked grind grading in present most of ore dressing plants is simple control automatically, even still adopts manually operated method, and not only efficient is low, and error is also bigger.
Summary of the invention
The purpose of this utility model is to overcome top described problem, and a kind of ore grinding intelligence step control equipment is provided, and can better improve the effect of grind grading, thereby enhance productivity greatly, reduces cost.
Ore dressing plant of the present utility model ore grinding intelligence step control equipment, it is characterized in that comprising host computer, by the Industrial Ethernet joining slave computer of host computer therewith, by controlling the net joining measuring instrument of slave computer, topworks therewith, form the opertaing device that integrates detection, control, monitoring management function.
Described slave computer is the PLC system, comprises power module, the joining CPU of power module therewith, joining, the one group of I/O mould rubbish plate being set up in parallel of power module, CPU therewith respectively.
Described measuring instrument comprises to the ore deposit flow instrumentation, adds discharge measuring instrument, grinding machine bearing temperature measuring instrument, pump pit level measuring instrument, cyclone entrance concentration measuring instrument for mineral water flow instrumentation, ore discharge discharge measuring instrument, pump pond.
Described topworks comprises device start/shut-down mechanism, frequency control mechanism, valve regulated mechanism.
Host computer major control function comprises that grinding process control, control panel operation, real time data demonstration, equipment running status demonstration, motorized valve control, alarm indication, equipment open/stops, control mode is selected and audio alert etc.Slave computer is responsible for data acquisition and control, can break away from upper main frame and work alone, and host computer is responsible for the monitoring management of control system, and host computer carries out communication by a built-in Industrial Ethernet network interface card and slave computer.
The software systems that ore dressing plant of the present utility model ore grinding intelligence step control equipment is adopted comprise the Control Software of slave computer PLC and the monitoring software of host computer.The design of PLC Control Software mainly comprises writing of hardware configuration and parameter setting, communication definitions and user program etc.The control program of native system is mainly controlled, is added water management to mineral water control, ore discharge water management, pump pond by master routine and the sequential control of grinding machine ore feeder, mine-supplying quantity.Subroutine modules such as the control of cyclone entrance concentration, the control of pump pit level control enclosure motorized valve constitute.Whether each subroutine call will be judged according to the relevant controlled variable that host computer passes down.Design 1s clock interrupt routine module and 100ms cycle interruption handler module in addition, wherein the 1s interrupt routine is used for realizing the fuzzy control and the parameter warning function of grinding machine, and 100ms cycle interruption handling procedure is used for realizing the calculating of data sampling and grinding machine reference current value and the functions such as " tripe expands " judgement of grinding machine.
Have high reliability, high anti-jamming capacity in order to ensure control system, native system has adopted different control methods such as interlocked control, PID control, tandem control, model control, fuzzy control, realizes the intellectuality control of grind grading jointly.
That opertaing device of the present utility model has is easy to operate, control flexibly, reliable in quality, powerful, can regulate operating parameter real-time and accurately, and then improve the work efficiency and the product quality of grind grading, economic benefit and obvious social benefit improve.
