Further, the shut-off valve A, shut-off valve B, shutoff valve C are normally open.
Compared with the prior art, the advantages of the utility model are:
1, reasonable design, improves drilling rod, drill bit service performance in a high temperauture environment, extends its service life,
Drilling rod is set to reach efficient drilling depth simultaneously.
2, since there are the pressure that wind pressure and atomized water generate in iron mouth pore passage when wind, water are cooling, retreat brill tapping outlet
During brill, there are certain gas compartments between drill bit and high temperature slag iron, prevent the direct of drilling rod, drill bit and high temperature slag iron
Contact, avoids drill bit, drilling rod by molten iron scaling loss.
3, using tapping machine purging, cooling and fog lubrication control system measure, drilling rod, drill bit are direct compared with before technological transformation
The usage amount of expendable part significantly reduces, and shortens the tapping outlet time, improves iron mouth qualification rate, alleviates labor intensity of workers,
Reduce blast fumance cost.
4, using cooling water, purging, integrate cooling, chip removal, can effectively at work carry out drilling rod, drill bit cold
But cool down, drilling rod and drill bit can repeatedly use, and sufficiently excavate the potential that equipment itself has, and reduce stokehold consumption.
5, flue dust, dust pollution are greatly lowered, and effectively control the pollution of iron mouth secondary smoke, improve stokehold worker's
Work situation.
6, iron time percent of punctuality, tapping evening ratio, iron mouth serviceability rate, rod boring rate are improved, apparent economic effect is obtained
Benefit has established solid foundation for blast furnace stable and high yields.
7, the utility model technology is popularized in an all-round way and is applied, and achieves good result, generate great economic benefit and
Social benefit.
