Blast furnace compaction type vertical stock rod drum shaft composite sealing device

Abstract

An improved composite sealer of compact vertical probe in blast furnace is installed between bearing supports and both ends of a body. One end of a coiling shaft assembly works in high temperature zone and the other works in Three sealers are designed at the hot terminal, first one consisting of sealing cover, pressing cover and filler ring; second one consisting of sealing cover and pressing cover in zigzag way; and third one arranged between shaft and pressing cover. A pre-fastened sealer is arranged at cool terminal, consisting of transparent cover, sealing ring with coil and seat. Sealing structure is respectively used at both ends of the bearing seat with water cooling tank. The sealing structure is high-temperature resisting, dust-proof and leakage-proof so as have long service life.

Description

technical field [0001] The invention relates to matching material detection equipment for an iron-making blast furnace, and is a composite sealing device adopted by a compact vertical probe reel shaft of the blast furnace. Background technique [0002] At present, the various types of furnace roof probes used in ironmaking blast furnaces have imperfect design of the reel shaft sealing device, and they have been working in a high-temperature and high-pressure gas environment for a long time, and are affected by heat conduction and heat radiation. The leakage of gas, the aging of sealing components is too fast, the bearings are overheated and carbonized due to grease, and the furnace dust enters to cause wear and tear failures and other disadvantages, which bring hidden dangers to the normal maintenance and safe production of the blast furnace, and sometimes even cause production accidents such as short-term shutdown of the blast furnace , the existing problems and disadvantag...

[0002] At present, the various types of furnace roof probes used in ironmaking blast furnaces have imperfect design of the reel shaft sealing device, and they have been working in a high-temperature and high-pressure gas environment for a long time, and are affected by heat conduction and heat radiation. The leakage of gas, the aging of sealing components is too fast, the bearings are overheated and carbonized due to grease, and the furnace dust enters to cause wear and tear failures and other disadvantages, which bring hidden dangers to the normal maintenance and safe production of the blast furnace, and sometimes even cause production accidents such as short-term shutdown of the blast furnace , the existing problems and disadvantages of the existing drum shaft sealing device need to be solved urgently
