Large-scale mill process control system

Abstract

A large-scale mill process control system relates to mining machinery, particularly a large-scale mill process control system that, through discrimination, avoids distorted signals and effectively avoids frequent shutdowns due to false alarms and faults. The large-scale mill process control system of the invention is installed on the mill and is characterized by comprising an internal structure, an external auxiliary unit and a mill monitoring system, wherein the internal structure, the external auxiliary unit and the mill monitoring system are connected by wires. The invention prevents distortion signals from entering the logical interlocking control unit and avoids frequent shutdown of the mill due to false alarms and faults by performing discrimination on all the detection signals of the external sensor, adds predictive control functions of mechanical properties to effectively control the degree of mechanical damage to bearings, bearing bushes, gears, etc., adds an online operationfault handling function, enables the gear oil lubrication, temperature detection and other faults to be handled without stopping the machine, and reduces the frequency of unnecessary shutdown of the mill.

Description

technical field [0001] The invention relates to mining machinery, in particular to a large-scale mill process control system which avoids distorted signals and effectively avoids frequent shutdowns caused by false alarms and faults through screening and processing. Background technique [0002] At present, the design concept of the lubrication control system of the copper mine mill with a daily processing capacity of more than 10,000 tons in China is relatively old and traditional, and most of it is designed by applying signal detection and control under ideal environmental conditions. Failure to solve the problem of frequent shutdowns caused by electromagnetic interference, dust, oil pollution, vibration and other harsh environments; unable to predict the pathological state of the mill machinery, once a failure occurs, the mechanical damage will be enlarged, and it is extremely difficult to repair; and it is not possible to pass The method of troubleshooting online operatio...

AI Technical Summary

Problems solved by technology

[0004] What the present invention aims to solve is the problem that the existing copper mine mill lubrication control system is not designed scientifically and is easily interfered by distorted signals when used in a harsh environment, resulting in frequent shutdowns. A large mill process control system that avoids frequent shutdowns due to false alarms and failures
