振动筛筛网固定装置的试验研究

Experiment and Research on Jigging Sieve for Solid Phase Pellet

针对振动筛在镁粒和镁合金粒筛分过程中存在的筛网绷紧不均匀、一次筛分效率低、限上率超标、筛网寿命低等问题,在现场工艺试验的基础上,设计了结构简单、安装方便、使筛网绷紧均匀的卷轴式筛网绷紧装置和可靠、简便的卡瓦锁紧机构,设计安装了筛网后挡料板,有效防止了镁粒和镁合金粒从筛网后部溅入而产生的混料现象。

On the conditional that the sieving bending was not uniform, the first sieving efficiency was low. The oversize rate was exceeded and the life of the sieve mesh was short in the process of the sieving magnesium pellet and alloy of magnesium, the sieve mesh bending device of the linar jigging sieve for solid pellet was deigned and improved based on the techanics experiment on field, and the sieve bending device, the clip locking mechanism was applied, the rare blocking board was designed and installed, so that it prevented the magnesium pellet and alloy of magnesium from splashing from the rare of the sieve mesh and avoided the product mixing.
