XHK-8000 automatic control system in cyaniding workshop

 

Application field

XHK-8000 automatic control system in cyaniding workshop is first developed by Xinhai Electromechanics Testing & Control Company in China and is successfully applied in many gold cyaniding workshop to realize full automation of workshop control and makes the technological process in the potimum condition. It basically sloves the problem of instability of supervisory control by manual operation in the cyaniding process, improves the leaching ratio, reduces the labor intensity of operators and improves the managerial skill of company.

Content

Control the grinding and classifying process before leaching.  Control the PH value during leaching and automatic adding reagent amount. Control the liquid level of many points and flow amount.Control the slurry density in the cyanating processControl the air injection amount in the cyanating process.Control the process of section replacement Control the energy saving of power equipmentControl the filter pressing of tailings Control the pressure of deoxidation.

Characteristic

The master control room controls the main station and substation separating on site to realize the supervisory control of the whole technic process.Sub-station CUP shares the work of main station CPU to realize the soft redundance of system and so the system will never have paralysis.This system integrates expert PID, fogging intelligent control, PLC and frequency control technology.The sub-system is designed with many modules and the customer can optionally choose any sub-system combination according to the requirement. The computer can display the operating condition of all equipments and any motor can start or stop in long range or on site.It adopts closed cycle control with the function of accurate alarm of upper and lower limit of control parameter and failure of equipments.The parameter of every monitory point can be displayed and adjusted optionally.The data can be collected and stated completely and the upper computer can send the data to the managerial department by the local area net of the company.The trend map of importment parameters can be displayed for 72 hours, which is convenent to technology analysis on site. It has visualized human-computer interface and every techonology flow interface can be changed optionally.The report and statistical result of all parameters can be printed at any time.The system is stable with high reliability, large running speed, good opening and expansibility.

Introduction of some sub-system

Sub-system of liquid level control: it consistes of PLC, transmitter of liquid level, frequency governor. It can accurately control the liquid level of slurry and the operation condition of every pump. It has audible and visual alarm when the liquid level exceeds the limit or the motor has failure. Sub-system of adding reagent control: The value of flow quantity can be setted by upper computer or on site. PLC has intelligence control of the flow amount of peristaltic pump. The reagent amount can be adjusted accurately accroding to the time or PH value.Sub-system of air compressor energy saving control: Expert PID controller is adopted to automatically confirm the best parameter. PLC realizes the group control of many computers. The frequency control can make the motor in the best operation. It has the function of operation supervisory control and protection.Sub-system of density control: nucleon densimeter is used to check the slurry density. It controls the flow amount of dilution water calculated by PID through electrical control valve and keeps the slurry density in the potimum scope. Sub-system of accounting filterpress filter cake discharge: It can record the number of drawplate in the upper computer, which will complete the accounting of filterpress filter cake discharge. The accounting result will be delivered to managerial department by local area network of company. Sub-system of desoxidation pressure control: fuzzy control is adpoted. It changes the control method based on experts experiences into automatic control method. The signal of deoxygenation tower pressure transmitter can make negative pressure stable by electric control valve.
