乌里扬诺夫斯基综合工艺研究所研制并试验了一种可从切削区到磨屑与冷却液混合区清除磨削杂质的装置。尘屑收集器(图1)包括由外壁2、内壁3、侧壁4组成的管筒1。管筒借助与其固定连接的撑板5用螺钉紧固于砂轮7的罩壳6上。在壁2的上边缘装有喷口9。尘屑收集器根据砂轮的磨损量可沿撑板5上的槽孔移动。装置的工作过程如下。杂质流从切削区落入管筒1,在管筒中,壁2用作分离冲洗零件8后的冷却液与杂质,而位于杂质流过道上的壁3,可把杂质导入收集箱。与杂质分离的冷却液落入精滤系统并重新供给磨削区。为了提高分离冷却液与杂质的可靠性,可通过管道把压缩空气输入喷口9,形成隔离层。
The Ulyanovsky Institute for Integrated Process Technology developed and tested a device that removes grinding impurities from the cutting zone to the mixture of abrasive and coolant. The dust collector (FIG. 1) comprises a tube 1 composed of an outer wall 2, an inner wall 3 and a side wall 4. The tube is fastened to the casing 6 of the grindstone 7 by means of a spreader 5 fixedly connected thereto. At the upper edge of the wall 2 there is a spout 9. The dust collector can move along the slot on the support plate 5 according to the wear amount of the grinding wheel. Device work process is as follows. Impurity flow falls from the cutting zone into the barrel 1 in which the wall 2 acts to separate the coolant and the contaminants from the rinse part 8 and the wall 3 on the flow path of the contaminants can introduce impurities into the collecting tank. The coolant separated from the impurities falls into the fine filtration system and is fed back to the grinding zone. In order to improve the reliability of the separation of the coolant and the impurities, the compressed air can be supplied to the nozzle 9 through a pipe to form a separation layer.
