石煤提钒制球工艺的自动化系统设计

Automation System Design About Vanadium Extraction From Stone Coal Making Ball Process

在襄阳某厂的石煤提钒制球工艺过程中,污染情况比较严重,对现场操作工人的身体健康造成极大危害,现根据生产设备和工艺要求,结合在工业自动化监控系统中广泛使用的PLC技术,通过PLC"采集数据,分析数据,处理数据"的运行流程来控制设备的运行及参数;利用PLC编程软件SIEMATIC STEP 7模块化编程,并使用梯形图或语句表编写程序,选用Siemens MM440型变频器,对电机进行调速,利用Visual C++编写监控界面,对设备运行状态实时监控,同时运用计算机控制、网络通信、总线传输等技术,实现石煤提钒制球过程的自动化、智能化,进而达到提高生产效益并降低生产成本的目的,而且也可将此系统框架应用于类似的监控场合。

In the process of vanadium extraction from stone coal making ball process of Xiang Yang’factory,pollution is more serious,which do great harm to on-site workers’health.Now according to the production equipment and process requirements,combining with the widely used PLC technology in industrial automation monitoring and control system,through the process of PLC“collecting data,analyzing data,processing data”control the equipment operation and parameter.Using the modular programming of PLC programming software SIEM ATIC STEP 7 and using the ladder diagram or statement list compile program.Selecting the Siemens M M 440 frequency converter change the motor’s speed,using Visual C++write monitoring interface to make the real-time monitoring system.at the same time,applying computer control,network communication,bus transaction technology make the automation and intelligence of vanadium extraction from stone coal,thus improve the production efficiency and reduce the production cost,which have important significance in similar application situations.
