Column Flotation Foam Thickness Of The Automatic Detection And Control

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.
