我矿在用反修100向下凿孔的过程中,多次发生钎头碎片掉入孔内,致使凿孔工作不能正常进行。为了打捞孔内的合金碎片,我们做了如图所示的“孔内合金碎片打捞器”,经多次使用,效果很好。这种打捞器结构简单,制做容易,使用方便,比用黄泥粘取合金碎片效果显著。具体操作如下:将打捞器放入孔底,打捞器后面的胶管接在压缩空气控制阀上,打开控制阀门,压缩空气经胶管到打捞器出口喷出,使孔底的水、碎石及碎合金片等被吹离孔底。关闭控制阀门,合金碎片及部分碎石、水等即能落入小漏斗中,一般经
Mine mine anti-revision 100 downhole in the process of drilling bits of debris fell into the hole many times, resulting in the work of perforating can not be normal. In order to salvage the alloy fragments within the hole, we made the “hole alloy debris” as shown in the figure, after repeated use, the effect is very good. This salvage device has the advantages of simple structure, easy manufacture and convenient use, and the effect is obviously better than that of alloy sticking with yellow mud. The specific operation is as follows: the salvage into the bottom of the hole, the salvage hose connected to the compressed air control valve, open the control valve, the compressed air through the hose to the salvage outlet, so that the bottom hole of water, gravel and broken Alloy sheet is blown away from the bottom of the hole. Close the control valve, alloy fragments and some gravel, water, etc. can fall into the small funnel, usually by
