我厂对八十年代初安装使用的4×6×3 m的水爆清砂池作了些改进,提高了使用性能,现介绍如下。一、悬挂摆动筛的改进水爆池除了使铸件进行水爆清砂外,还有使旧砂回收再生的重要作用。这一任务的实现,主要靠池内中间摆动格筛来完成。摆动筛原设计是悬挂式支承结构,由四根d=16mm,t=44mm的圆环起重链用索具卸扣吊挂在池体的悬臂上,如图1。 I plant on the installation and use of the early eighties 4 × 6 × 3 m of water burst Qingzhu made some improvements to improve the performance, are described below. First, the suspension swinging sieve improved water burst pool in addition to the water blast blasting sand, there is an important role in recycling old sand. The realization of this task, mainly by the central swing grid sieve to complete. Swing screen original design is hanging support structure, the four d = 16mm, t = 44mm ring lifting chain hanging with a sling on the pool body cantilever, shown in Figure 1.
