Wagon unloading system for coal handling and transporting
Wagon unloading System is designed for bulk material unloading system, which is used for the dumping of bulk materials loaded by trains. The wagon unloading system has high unloading efficiency and less damage to rail cars. It can improve the working environment of personnel on duty and facilitate the automatic control of machinery. With the continuous development of the national economy, the consumption of bulk materials transported by train such as coal, coke and ore required for the construction of thermal power plants, smelters, cement plants, ports and mines has increased significantly. The wagon unloading system has been widely used in large modern enterprises.
There are many forms of wagon unloading system, which can be divided into through type and turn back type according to the process of wagon unloading system. According to the structural form, it can be divided into rotor type, roll type, end unloading type and composite type, among which the most used is a rotary wagon unloading. The Wagon unloading can be divided into O-shape and C-shape. At the same time, it can also be divided into steel wire drive and gear drive according to the driving force mode of car dumper. It can also be divided into "single turnover", "double turnover" and "three turnovers" according to the turnover capacity of the wagon unloading. The largest capacity wagon unloading system can unload 4 cars at a time. According to relevant data, the maximum daily utilization hours of wagon unloading is 12h. Since the incoming train may not be able to unload in time after arrival, there will be some interruption of waiting time and station train inspection time. Therefore, the daily actual effective time of the wagon unloading is 10h, that is, the average effective time utilization rate is 40%. If the average load of each vehicle is calculated as 60t, the daily average comprehensive production capacity of a wagon unloading can reach about 15000t (day and night).
