Abstract
The utility model relates to a bearing protecting device, particularly to a protecting device for a trunnion bearing of converter. The utility model is characterized in that the utilility model adopts labyrinth bearing sealing; a slag collecting groove for collecting accumulated objects, such as slag, grain steel, dust, etc. is arranged on a transparent cover, the upper part of the transparent cover is provided with a blowing pipe, the lower part is provided with a slag discharging hole, and the accumulated objects are removed through blowing.
Description
The utility model relates to protector, is specially a kind of trunnion of converter bearing protection device.
In the converter steelmaking process, the time have slag, the grain steel splash around the body of heater, these slags with the grain steel usually fall on the trunnion of converter bearing body, influence the normal running of converter.For the foreign material of removing in the trunnion of converter bearing want heat to stop work, sometimes even the stopping production of long period, like this equipment operation and production have been brought harm.Generally adopt the protection of rubber asbestos mat for this reason, give the provide protection of thinking, have a strong impact on normally carrying out of converter production but under hot environment and splash condition, be difficult to play.
The purpose of this utility model provides a kind of device that protection can be provided the trunnion of converter bearing under the more severe environment of high temperature, spray slag grit blast steel and dust.
In order to achieve the above object, the utility model adopts the saturating lid of labyrinthic bearing envelope, and a slag deposition groove that stores grain slag, grain steel, dust etc. is set within it, and its top is provided with scavenging duct, and the bottom is provided with mud hole.
Because the utility model adopted labyrinthic bearing seal, and by in time purging with pressurized air to being located at its saturating lid mouthful slag deposition groove, can prolong trunnion of converter bearing work-ing life effectively, improve the converter operating rate.
Below in conjunction with description of drawings formation of the present utility model:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that the structure cross-sectional schematic of (1) is covered in bearing seal thoroughly
The utility model comprises that bearing seal covers (1), bearing support (2), bearing (3), transmission shaft (4), end cap (5) thoroughly.The structure of the saturating lid of sealing (1) comprises purge hole (6), mystery palace slag deposition groove (7), mud hole (8), metal envelope element (9) as shown in Figure 2.Transmission shaft (4) and bearing (3) are tumblers, and all the other are fixed static elements, and when grate not, transmission shaft (4) and bearing (3) remain static; Transmission shaft during grate (4) and bearing (3) cover (1) thoroughly with bearing seal and produce relative rotation.Under conventional environment, lock packing adopts felt, rubber, polytetrafluoroethylene etc. can reach sealing, but under severe environment such as the high temperature of converter smelting, many slags, grain steel, many dust, above-mentioned way is impracticable.The utility model dwindles the tolerance clearance of bearing air cover (1) and transmission shaft (4) as far as possible for this reason, establish labyrinthic slag deposition groove (7) in saturating lid (1) body, enter lid (1) as a small amount of foreign material from tolerance clearance, at this moment the foreign material of being invaded enter in the mystery palace slag deposition groove (7) in the lid (1), can irregularly blow by purge hole (6) with pressurized air, foreign material are discharged from mud hole (8).At bearing air cover (1) installed inside Demountable metallic sealing element (9), even pyritous slag and grain steel are invaded and contacted on the metal seal also unlikely scaling loss bearing.
The utility model confirms through test, can make the safe operation reliably of trunnion of converter bearing under the severe environment of converter smelting splash, improves the converter operating rate effectively.
Claims (3)
1, a kind of trunnion of converter bearing protection device; it comprises that bearing seal covers (1), end cap (5), bearing support (2) and coupling device thereof thoroughly, it is characterized in that: bearing seal is covered thoroughly in the body of (1) and is also established a mystery palace slag deposition groove (7) that stores foreign material such as a grain slag, grain steel, dust.
2, a kind of trunnion of converter bearing protection device according to claim 1 is characterized in that: the upper/lower terminal of slag deposition groove (7) respectively is provided with gas hole (6) and the mud hole (8) that purges foreign material in the slag deposition groove with pressurized air.
3, a kind of trunnion of converter bearing protection device according to claim 2 is characterized in that: there is Demountable metallic sealing element (9) inboard that (1) is covered in bearing seal thoroughly.
