Problems solved by technology

[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

Embodiment Construction

[0013] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0014] The blast furnace compact vertical probe drum shaft composite sealing device is placed between the two ends of the drum shaft 15 and the bearing seat 4 . One end of the reel shaft 15 is the high temperature side, and the other end of the coupling is the low temperature side, wherein:

[0015] The high temperature side of the mandrel shaft 15 includes three seals, that is, the first seal consisting of the sealing cover 1, the gland 13 and the packing ring 2 woven with a flexible graphite packing ring with high temperature resistance and dustproof effect, The second mechanical labyrinth seal composed of the sealing cover 1 and the gland 13, and the third seal formed by setting the silicone rubber O-ring 14 between the gland 13 and the reel shaft 15.

[0016] The low temperature side of the reel shaft 15 adopts a pre-tightened seal, which is composed of a t...

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...
