The Engineering Design And Control Technology Of Coal Storage And Blending System

The Digital-base project of Caofeidian Coal Storage and distribution is to plan the total coal circulation is 25 million t/a,a dynamic storage capacity of 720 thousand tons of large coal storage and distribution base,is the focus of planning project of Caofeidian port area,which will become the center of coal reservoir with high flow,high precision,digital.Large flow is the system throughput capacity.Digital is the operation of digital,digital control,operation of digital,digital management.High precision is transport system with high precision and high precision,the product index of coal blending system with high precision.The project of integrated automation system design by the "network","process control system","blending expert system","security monitoring and dispatching system" and "computer system","information management system" etc.This research mainly deals with system design and control system design of coal blending process.The production process of the centralized control system with PLC control system as the core,the control method and control method for PLC + station substation,central control tasks were completed all related process equipment.Coal storage system for the control of coal belt began to check all the stacker controlled equipment;loading coal handling system control range from the beginning of the reclaimer,which to check all the shipment transfer station controlled equipment.The project design and implementation of centralized monitoring and control to the 17 belt machine as the main equipment,and provides the interface-access circular stacker reclaimer,high pressure system;in accordance with the requirements in the installation process by blending expert system to achieve precise optimal coal blending,coal blending,coal production to meet customer requirements of goods.Increase the value of coal,so that the maximum efficiency of enterprises.
