APPARATUS FOR OPENING TOP BUNKER-PRESSURE DETECTING PART FOR BLAST FURNACE

摘要

PURPOSE: A device for opening a pressure detection terminal of a furnace exposed bunker is provided to prevent the gas poisoning of workers due to a gas leakage and to enable the terminal to be always opened. CONSTITUTION: A device for opening a pressure detection terminal of a furnace exposed bunker includes a first dust removing unit (100), a first opening valve (200), and a dust removing unit (300). The first dust removing unit selectively supplies the gas of high pressures to a short pipe. The first opening valve selectively closes the short pipe. The second dust removing unit removes dust attached on the gas pipe of the furnace exposed bunker while sliding and moving to the inside of the short pipe. The first dust removing unit includes a high-pressure gas pipe (110) connected to one side of the short pipe; and a second opening valve (120) selectively opening the high-pressure gas pipe.
