The Electrical Design Of Shaba Land Mine Incline Shaft Drive Belt System In Guizhou Kailin Group

Phosphate rock is a very important basic raw material of phosphorus chemicalproduction, but also the important raw material for production of industrial fuel.Which is plays an important role in the national economy. The main features ofphosphate resources in China is a large mineral reserves, mineral resources are moreconcentrated, phosphate rock collection difficult. In order to improve ore productioncapacity, increasing the recovery rate of ore. Guizhou Kailin Group commissionedChangsha Institute of China Ministry of Chemical Industry to this Extension ofmining project in Shaba land mine transformation projectsIn this paper, as the research object to the project, design shaft drive circuit tapetransport system. By comparing the three types of motor speed control mode and startmode, We conclude that in the large capacity, long distance, and to require more thanone motor drive shaft running speed tape transport system, using the transducer tocontrol the AC motor speed control system to achieve a smooth start and steplessspeed control is the best Methods, Therefore using the PowerFlex700S (heavy duty)for the main drive motor voltage starting circuit and the exchange rate adjustment inthe transport system in the main circuit of the motor and the motor with frequencyconverter and PLC joint control, the motor can power balance and long-term stabilityunder the conditions of the speed of operation. Drive system design manual relaycontrol by PLC automatic control loop circuit and a parallel control, to protect thedevice in action to occur automatically stop running the whole transport system, toachieve an accident shut down the system downtime by detecting the cause and site ofthe accident in the simulation screen on the display. This makes it easy for entiremonitoring and centralized control of the entire system load, unload and transport.The main outcome of the project is completed Extension of mining project inGuizhou Kailin Group Shaba land mine CAD design of electrical drive systems. Use itas a theoretical guidance to the construction site, Greatly improved the efficiency ofthe mining system.
