斗式提升机是一种具有功耗低、占地小、功率高,造价低等独特优点的连续垂直输送设备,在粮食行业和其它行业都得到极为广泛的应用。但斗式提升机过载能力差,易出故障。轻者造成粮食堵塞,重则打坏畚斗,撕毁畚斗带,甚至会引起粉尘爆炸等恶性事故。这对流水作业,特别是象筒仓作业的安全生产危害极大。为此斗式提升机安全生产技术引起国内外各方面专家的严重关注。 82年以来,我们结合上海市第六粮食仓库筒仓作业微机自控系统工程项目对筒仓作业的心脏设备——斗式提升机的安全技术作了研究和探讨,积累了一些感性和理性认识,现在综合如下:
Bucket elevator is a continuous vertical conveyor with unique advantages of low power consumption, small footprint, high power and low cost. It has been widely used in the grain industry and other industries. However, bucket elevator overloading capacity is poor, prone to failure. The light caused by food clogging, while the heavy blow fight, tear the bucket belt, and even lead to dust explosion and other serious accidents. This is a great danger to the flow of work, especially the safety of silo operations. To this end bucket elevator safety production technology has caused serious concern of all experts at home and abroad. Since 82 years, we have studied and discussed the safety technology of the bucket elevator, which is the heart equipment of the silo operation, in combination with the project of microcomputer control system of silos in Shanghai No. 6 Food Warehouse. We have accumulated a number of sensibilities and rational understandings, Now integrated as follows:
