浮选柱泡沫层厚度的自动检测与控制
|
摘要
近年来,浮选柱作为一种高效的选矿设备,在有色及黑色金属矿物、煤炭、非金属及化工矿物分选领域的应用不断推广。然而,浮选柱生产过程的自动化技术却发展缓慢。目前对于泡沫层厚度的检测及控制采用的方式主要是人工测控,由操作工人根据对浮选泡沫状态的观察来进行控制,这种方式在很大程度上取决于操作者的经验和能力,可靠性比较差。因此,加强浮选柱矿浆液位和泡沫厚度的自动检测及控制方面的研发工作尤为重要。
本文以浮选柱泡沫层厚度监控为研究对象,在实验室自制浮选柱基础上,设计研究了一套浮选柱泡沫层厚度自动检测及其控制系统。提出采用压力变送器和非接触式超声波液位计来分别检测矿浆液位和泡沫液位,进而测得泡沫层厚度的间接检测策略。
本文首先介绍并分析了国内外对于浮选柱矿浆液位以及泡沫层厚度检测及控制的现状,针对浮选柱恶劣的工作环境,设计研究了一套采用间接检测泡沫层厚度的监控系统。同时利用Kingview6.5组态软件及中泰ZT400-4000系列数据采集模块开发了一套计算机数据采集控制系统,实现对传感器检测的实时数据进行采集、存储、打印及调用等功能,并且实现了对浮选柱的一些基本控制。最后,根据系统设计要求,完成了基于组态软件的控制系统界面以及其它相关画面的制作、组态软件内部程序编制、系统总体调试等工作。并且利用其内部PID标准控件来作为系统的控制器。实现了泡沫厚度的控制。
In recent years, as a new kind of highly effective beneficiation equipment, the flotation column has become more useful in the colored and the ferrous metal mineral、the coal and the chemical mineral separation domain. However, the automated technology of the flotation column actually develops very slowly. At present, the way which uses to detect and control the froth thickness of the flotation column is mainly by the manual observation, This way is decided to a great extent by operator's experience and ability.so,the reliability is not good. Along with industrialization application promotion,it is very important to study of automatic detection and control for the froth thickness and pulp level of the flotation column.
This paper which makes froth thickness automatic control system of the flotation column as research object.Based on self-restraint flotation column,Has designed a automatic detection and the control system for froth level thickness.It suggests that uses the pressure transmitting instrument and the non-contact ultrasonic wave liquidometer examines the pulp level and froth level separately,and then we can obtains the froth thickness indirect.
This paper first analyzed the research situation of automatic control system for flotation column froth thickness. In view of the bad working conditions of the flotation column,this paper designed indirect automatic control system for flotation column froth thickness. Meanwhile, has developed a set of computer data collecting and controlling system using the Kingview6.5 configuration software and the zhong-Tai ZT400-4000 series data collecting and converting molds. With this system, we can collect the pressure sensors'signal and ultrasonic's signal and so on gathering, memory, printing and realize some basic control to the flotation column. Finally, according to the system design request, has completed based on the configuration software's control system contact surface as well as other related picture manufacture, configuration software work and so on internal procedure establishment, system overall debugging. And uses its internal standard PID as system's controller. Has realized the froth thickness control.
