我厂铸铁车间旧砂回收采用风力吸送。但此法的缺点是管道磨损厉害,特别是弯头的磨损更为突出(图1)。为提高弯头寿命,减少磨损,我们采用了3毫米厚的A3钢板制成如图2所示的结构,并在生产上进行验证。从三个月的生产实践来看,效果较好,未发现任何问题。生产率没有变化,使用寿命显著增加。

Our factory used cast iron workshop sand recycling by wind suction. But the disadvantage of this method is that the pipe is badly worn, especially the elbow wear is more prominent (Figure 1). In order to improve elbow life and reduce wear, we use a 3 mm thick A3 steel plate structure shown in Figure 2, and verify the production. From the three months of production practice, the effect is better, did not find any problems. No change in productivity, life expectancy increased significantly.
