【摘要】 在现代科学技术的许多领域,自动监控系统起着日益重要的作用。就选矿方面而言,国际上,选矿过程自动化的研究始于五十年代,从检测到监控;从单参数控制到机组、全作业、全厂控制;从模拟仪表控制到计算机控制;从稳定化控制到最优化控制,选矿自动化已由低级到高级而日趋完善,特别是计算机用于过程控制,以现代理论指导生产实践,使选矿自动化水平达到新的高度。浮选过程的自动控制历来是一个令人头痛的问题,主要原因是浮选过程自身的复杂性及其对过程干扰的敏感性。70年代载流荧光分析系统的研制成功为研究在线的浮选过程控制系统提供了可能。随着第1台过程控制用计算机的研制成功,选矿自动化的研究人员首先成功地开发了磨矿控制系统,这为1976年第1套浮选过程计算机控制系统的研究成功铺平了道路。在过去的20年里,芬兰、澳大利亚、加拿大、美国等国家的研究人员仍然在此领域进行了不懈的努力,并取得了一定的成就。在此之后神经元网络、模糊逻辑控制、自适应控制及专家系统等先进的控制策略成功地应用于浮选过程控制的报道也不少见。 浮选是最重要的选矿方法之一。据统计,90%的有色金属矿用浮选法处理。浮选法还广泛用于稀有金属、贵金属、黑色金属、非金属如煤等矿物原料的选别。浮选药剂的添加是浮选生产工艺中的一个重要环节,添加量的大小、准确与否都直接影响着产品的数、质量及效益。传统的人工调节方式既不准确也不及时。而浮选自动加药控制系统的应用,不但克服了人工调节的缺点,而且降低了浮选生产的药耗,为选厂带来直接的经济效益,同时减轻了岗位工人的劳动强度。 本课题是针对攀钢集团钛业公司密地选钛厂浮选流程加药系统的监控、管理等问题,应用MCGS组态软件进行组态控制。论文首先对攀枝花—西昌地区钒钛磁铁矿的选矿特征和原生钛铁矿选矿技术进行了简单的介绍,并对浮选加药控制系统从传感器、数据采集、数据处理、执行机构等方面进行了详细的阐述。本课题的主要工作是应用MCGS组态软件对密地选钛厂浮选流程加药系统进行组态,以实现药剂添加的计算机控制。 密地选钛厂先用浮选法分选出硫化矿物。然后再浮选钛铁矿。硫化物浮选采用常规浮选药剂制度,即用黄药为捕收剂,98~#油为起泡剂。硫更多还原

【Abstract】 In a lot of fields of the modern science and technology, the automatic monitoring system plays an increasingly important role. As regards mineral processing, in the world, the research of course automation of the mineral processing started in the 1950s, from measuring to controlling; Control and control from the single parameter to the aircrew , the whole homework , the whole factory; Control and control from the appearance of imitating to the computer; Controlling it to optimizing controlling from melting steadily most, mineral processing automation has been already from rudimentary to advanced and becoming more perfect, especially the computer is used in the course to control , guides production practices with the modern theory, competence reaches the new height to automize mineral processing. The automatic control of the flotation course has always been a troubling question, the main reason is complexity of the flotation course and sensitiveness interfered to the course. Flow fluorescence analytical system which offer for studying the online flotation course control system make it possible to succeed in developing in the 1970s. The ones that controlled with the computer were developed successfully with the 1st course, researchers of mineral processing automation develop the ore control system of rubing successfully at first, this succeeds in paving the way for research of the course computer control system of 1st set of flotation of 1976. Over the past 20 years, the researchers of such countries as Finland, Australia , Canada , U.S.A. ,etc. that have still carried on untiring efforts in this field, have made certain achievement. After this, Neuron network, fuzzy logic control, self-adaptation control and expert system, etc. advanced control strategy have applied flotation report that course controls rare to succeed in.Flotation is one of the most important mineral processing methods . The statistics show, 90% of the nonferrous metals mining flotation law treatment. The flotation is still used in the selecting to leave of rare metal , noble metal , ferrous metal , nonmetal raw materials of mineral such as coal extensively. Adding an important link that is the flotation in a production technology of flotation drug, add quantity big or small accurate to influence number , quality , benefit ofproducts directly or not. The traditional artificial regulation way is inaccurate in time either. And the automatic application with medicine control system of flotation, not only has overcome the artificial shortcoming that regulates , and has reduced the medicine produced in flotation and dawdled , has brought the direct economic benefits for selecting the factory, lightenned post workers’ labour intensity at the same time.This subject is to such questions as control, management which selects flotation procedure medicine system in the MIDI titanium-processing mill of group of Panzhihua Iron and Steel Co. , using MCGS configuration software to control the configuration. Thesis catch to Panzhihua - Xichang area vanadium mineral processing characteristic , titanium of magnetic iron ore ilmenite mineral processing technology introduce the simple one originally at first, and has added the medicine control system and carried on detailed exposition from such respects as sensor , data gathering , data processing , executive body ,etc. to flotation. The groundwork of this subject is to use MCGS configuration software to selecting the MIDI titanium-processing mill’s flotation procedure medicine system to carry on the configuration, which is added to realize the drug computer control.The MIDI titanium-processing mill divide and elect sulphurate the mineral before flotation ilmenite. Sulphide flotation adopts the drug system of routine flotation, namely in order to catch and accept the pharmaceutical with the yellow medicine, pharmaceutical in order to bubble of oil "No. 98. The sulphuric acid is adjusted dose for pH. Catch and accept the pharmaceutical, sulphuric acid to produce flotation ilmenite for the adjustment pharmaceutical of pH with MOS. drug to add and control the configuration system of the MIDI titanium-processing mill, include controlling the main interface mainly, keep drug case control interface, drug is it control window , procedure and sensor interface, hydrogen ion index and PH real-time and history curve window.更多还原
