Research Of The Coke Dry Quenching Coke Cans Hoisting Machine Electrical System

Hoisting machine of the coking can is the key equipment for CDQ, which is alsospecial equipment for the red coke transferred to the dry quenching tank. With thedevelopment of modern industrial technology, its large-scale, automation and security,reliability requirements continue to increase, so the focus cans hoist the need for furtherin-depth research to enhance the machine control system to optimize and improve theirsecurity and the purpose of life and to improve labor productivity, enhance productcompetitiveness are of great practical value.This article from the system’s control system analysis, hardware components, softwareprogramming and anti-jamming measures four aspects of a detailed analysis of coke canshoist electrical automation control systems. In the control system analysis, by draggingand dc ac drag from the investment, land, ease of maintenance and other aspects wereanalyzed and compared to finalize AC drive system. Systematic analysis of the woundrotor induction motor speed control series resistance performance, advantages anddisadvantages, and with squirrel-cage induction motor with frequency accuracy for speedin the speed, investment and production processes to meet the requirements of otheraspects of the analysis and comparison of frequency speed its excellent speed performance,coke cans used to hoist control system. Hardware using PCC as the control system core,through the program command completes AF tank hoist each part of the equipmentcontrolled through communication with the control system CDQ realized hoist partsfeature automatic control. Using a variety of sophisticated software system data module,the ascension the various parts, the interlock between each operation, thereby improvingthe safety of the hoist and reliability. As harsh field environment hoist, hoist a variety ofinterference can cause malfunction, so the inverter, input and output modules, motors, etc.has taken anti-jamming measures, and achieved good results.Based on the Hangang1#2#coke75t CDQ coke cans hoist the project ’s technicalrequirements, was designed based on PLC as the control core frequency control system,put into operation more than two years from the operation look, safe and reliable operationof the equipment, high degree of automation of the process to fully meet the requirementsof the device in addition to normal maintenance, has no other fault occurs, which mayindicate that the control system of the same type hoist electrical control design has somepromotional value.
