Overview

Material transfer (coal) control system is made up of four parts:unloading system, loading system, feeding system and batching system.It mainly transmits meterial from sources to storage yard, and then transmits to host bunker or directly transmits from sources to host bunker.It dose the work of unloading, stacking, loading, ingredients and preparation tasks, in order to achieve the purpose of provide fuel for the unit with good quality.

 

Solution 

Delto DLT - WLCS8000 transfer material (coal) control system used the modern mature PLC and modern bus network and combined with the multimedia network monitoring technology, to monitor and control logarithmic kilometers long the material transfer process of all kinds of equipment, realize the whole system safety interlock start and stop at the same time.It aiso combined with advanced intelligent software technology to realize automatic measurement points furnace ingredients. The system main control object including: coal feeder, tee baffle, belt machine, crusher, iron remover, plough type coal unloading equipment and so on.

 

Functions and features

1) Coal transportation control. Automatic start-stop and interlock protection of coal equipment, output indicator, emergency trip, etc., automatic feeding.

2) Loading\unloading control. Loading\unloading control of the bucket wheel machine. 

3) Batching control. The weight sensor, ultrasonic level meter, or other material level are used to detective state of the coal bunker. The main equipment includign coal plough, coal unloading wagon.

4) Transfer station control. The main equipments including panel, three way diverter damper, gate door and so on, also including auxiliary equipment such as magnetic separator, metal detectors, coal feeder control, etc. 

5) Coal crusher control. Start-stop control, overload protection, interlock of vibration and overtemperature protection.

6) Measuring equipment. Control of the electronic belt scale with instantaneous value, accumulative value, print, record, display. Record the input and output of coal, etc. 

7) Alarm system. The accident report of equipment and personnel safety protection, exceptions, between coal bunker coal level is high, low, high-high, low-low, dynamic power failure, the coal conveying equipment and auxiliary, fire, dust, dust collection, sampling and HVAC system.
