未经烘干的新砂给过筛带来很大困难,过去用手工筛砂,劳动强度很高,生产效率很低。根据这种情况,厂领导要求我们一定要把笨重的体力劳动解放出来。设计人员经过学习毛主席著作,改变了过去苦思闷想的设计方法,深入现踢与操作人员一起参加劳动,摸索第一性资料,在不大长的时间内设计出一台冲击式筛砂机(见图),经过一年多的使用,筛含水量15％的湿砂,效果较好,生产效率较高,适应范围较广,用起来机动灵活。
It is very difficult to sieve the non-dried fresh sand. In the past, it was difficult to sieve the sand by hand, resulting in high labor intensity and low production efficiency. According to this situation, the leadership of the factory requires that we must liberate bulky physical labor. After studying Chairman Mao’s works, designers changed the design method of past experience and thoughtlessly. Now they kicked off work with operators to find first-class information and designed an impact-type sand screen in a short period of time Machine (see photo), after more than a year of use, the wet sieve containing 15% of the water content is better, the production efficiency is higher, the adaptability is wider and the machine is flexible.
