银山铅锌矿质量管理科为了解决选矿厂矿浆溢流样品集中分样劳动强度大、样品容易混杂等问题,利用废弃的吊筒加药机的传动机构,稍加改进,制成一台往复式溢流样品随取样机动作的延时缩分机。安装使用以来,取样机每次取样时,安装在取样机下面的缩分机也随取样机开动;取样机停止时,缩分机继续开动40秒钟后再停止,缩分后的样品又增加秤盘自然过滤;省略了集中分样和样品水分抽滤工序,样品代表性有了较大的提高。随取样机动作的延时缩分机所以能够达到上述功能,关键是延时电路的作用,见下图。
Yinshan lead-zinc quality management division In order to solve the concentrator ore slurry overflow sample intensive labor-intensive sample is easy to mix and other issues, the use of abandoned crane plus drug transmission mechanism, a little improvement, made a reciprocating Time-scale compressor with overflow sample flow with sampler. Since the installation and use, the sampling machine sampling each time, installed in the sampling machine below the shrinking machine with the sampling machine start; sampling machine stops, the shrinking machine to continue to start 40 seconds before stopping, Natural filtration; omit the focus on the sample and sample moisture extraction process, sample representative has been greatly improved. With the sampling machine delay delay extension machine so to achieve the above functions, the key is the role of delay circuit, see below.
