Study and application of the intelligent filter pressing system at Xiegou Mine Coal Preparation Plant

The filter pressing system of Xiegou Plant has a high labor demand.The work is done by labor-intensive operators mainly by relying on experience gained through practice.To tackle this problem, an intelligent operating mode is proposed for the integrated control and management of the system.Through adoption of this mode, the overall control and management of the operation of a number of filter presses can be effected through collecting the real-time operating parameters, analysis of collected data and background software algorithm.Intelligent upgrading of the system makes it possible to operate under coordinated control and management thanks to availability of the following functions:automatic supplying feed to filter presses, and making automatic judgement of the need for ending the feed supply.Application of this mode has led to decreased manpower requirements, elimination of the influence of artificial factors, reduced labor intensity and improved overall efficiency of entire system.
