The utility model discloses a blast furnace pulverized coal preparation system with vibration screen fault detection function, which comprises a coal mill, a bag box, an exhaust fan, a bag ash hopper and a pulverized coal bin. The air inlet of the bag box is connected with a coal mill, the air outlet is connected with the exhaust fan, and the pulverized coal outlet at the bottom of the bag box is connected with a bag ash hopper. The pulverized coal bunker is located below the bag ash hopper. The lower coal pipe of the bag ash hopper is connected with the coal inlet of the bunker through the lower coal valve group and the vibrating screen in turn. A temperature sensor is installed on the side wall of the bag ash hopper and the lower coal pipe of the coal inlet end of the vibrating screen. The signal output terminal of each temperature sensor is connected with the DCS of the blast furnace pulverized coal preparation system. The utility model uses a temperature sensor to monitor the temperature of the upper and lower coal pipes of the bag ash hopper and the vibrating screen in real time, and judges whether the vibrating screen has a fault according to the changes of the two, so that the fault of the vibrating screen can be detected and eliminated in time, the blockage of the lower coal pipe can be prevented for a long time, and the working efficiency of the coal powder preparation system can be improved. Rate.
【技术实现步骤摘要】
一种具有振筛故障检测功能的高炉煤粉制备系统
本技术涉及一种高炉煤粉制备系统,该系统可在振动筛出现故障时自动发出报警信息,属于磨粉或粉碎
技术介绍
高炉煤粉制备系统运行时,原煤经磨碎和干燥变为煤粉,然后沉降在收粉系统的布袋灰斗中,再沿下灰斗底部的下煤管道下落,经下煤阀组和震动筛进入煤粉仓内,最后从煤粉仓分装到各喷吹罐。生产过程中发现,震动筛是高炉煤粉制备系统中故障率较高的部件,一旦振动筛发生故障,其上部的下煤管道就会被煤粉堵塞,使煤粉无法输送到煤粉仓,从而影响生产的顺利进行。由于现有的高炉煤粉制备系统都没有故障检测功能,振动筛出现故障后一般很难及时发现,导致系统带故障运行时间延长,大大降低了高炉煤粉制备系统的工作效率。
技术实现思路
