面向绿色制造的长效冷却液净化系统研究

STUDY ON NON-DISCHARGE DECONTAMINATION SYSTEM OF COOLANT BASED ON GREEN MANUFACTURE

迄今废冷却液的排放源源不断。提出一种具有过滤和灭菌功能的不排放的冷却液净化系统,介绍了内吸刮渣式磁分离器和利用负压进行臭氧灭菌的迷宫的结构特点和设计思路。经扫描电镜分析,过滤后冷却液中的剩余渣粒直径小于15 μm。试验表明,与普通净化方法相比,使用该装置后的砂轮耐用度以及冷却液防锈性能得到较大提高,其他工艺指标如工件表面粗糙度也有所改善。微生物检测结果其灭菌率达99％以上。实现冷却液的不排放是绿色制造的一个组成环节。

The wasted coolant is continually discharged into the environment so far. A non-discharge decontamination system that integrates filtration and antisepsis of the coolant is presented. The design ideas of a magnetic separator, which removes dregs from the coolant by sucking from inside wall of the tub, and a maze, inside which ozone is introduced through decompression to perform antisepsis is discussed. The dreg within the filtrated coolant is less than 15 μm,analyzed by scanning electron microscope. Compared with other known decontamination methods, our system significantly improves the duration of the grinding wheel and the antirust performance of the coolant. Other machining technique performance, such as roughness of the workpiece surface, are also improved. As demonstrated by microorganism test, more than 99% of the bacteria are killed. The coolant non-discharge is regarded decontaminate as an integrated part of the green manufacture.
