本発明は、高炉の炉内点検に使用する高炉点検用覗き窓
保護装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a blast furnace inspection viewing window protection device used for inspecting the inside of a blast furnace.
［従来技術〕
高炉操業において、作業者は羽口の後方のペンストック

業者は覗き窓とペンストック金物との間の管路に設けら
れたコックを開いて観察し、点検後コックを閉じる。[Prior art] During blast furnace operation, workers observe the inside of the furnace through a viewing window attached to the penstock hardware behind the tuyere, observing the brightness at the tip of the tuyere, the swirling of coke, the adhesion of slag, and the appearance of the tuyere. Water leakage and furnace status are checked three times a day. These viewing windows are installed at approximately 40 locations in each blast furnace.During inspections, workers open the cock installed in the conduit between the viewing window and the penstock hardware, and after inspection, open the cock. close.
したがって、常時は高炉炉内ガスおよびこれに伴う粉塵
から遮断され、覗き窓を清掃することが可能である。Therefore, it is always shielded from the gas inside the blast furnace and the accompanying dust, making it possible to clean the viewing window.

装置を提案することをその目的とするものである。[Problem to be solved by the invention'H] However, in conventional devices, damage occurs to the sliding part of the cock due to thermal expansion of the cock and intrusion of dust.
The cock becomes unable to rotate and hot air flows outside. In such a case, the viewing window becomes unusable due to the blockage of the pipeline, and the tuyere cannot be inspected until the end of the day, which impairs operational safety.The present invention solves the above problems. The purpose of the present invention is to propose a viewing window protection device for blast furnace inspection that allows the viewing window to be used safely.

In order to open the space between the passage 3 inside the main body and the viewing window 4, use the handle 5 to turn the cock stopper 90 degrees. Align the through hole 6 of the cock stopper with the passage direction. A gasket 7 is interposed between the cock stopper and the cock body. The gland presser 8 presses the packing with the stud bolt 9 and nut 10. Since the area near the through hole of the cock is tapered, the cock receives an upward force due to gas pressure, so a thrust bearing 11 is installed at the end of the cock.
is installed. When inspecting the blast furnace tuyeres, the cock plug is rotated, but since it is always closed, the pressure is approximately 4.5 kg/ad.
pressure is applied to one side of the stopcock. In order to avoid the effects of gas pressure, the passage area was kept to a minimum, and the cock body and cock stopper were made of stainless steel. in this way,
The gasket prevents blast furnace gas from leaking and the accompanying dust from entering the cock plug.
