Description
Technical field
The utility model belongs to the plugging device of the big or middle set faying face gas leak of processing blast-furnace tuyere, particularly one kind
Handle the plugging device of the big or middle set faying face gas leak of blast-furnace tuyere.
Background technology
There is tuyere medium sleeve nose in large blast furnace at present, faying face leakage gas between tuyere big sleeve and tuyere medium sleeve, sternly
Ghost image rings employee and enterprise safety operation.The measure uniquely taken is exactly to change tuyere medium sleeve.Blast furnace long period periodical repair, disposably
20 tuyere medium sleeves are changed, directly increase about 460,000 yuan of producing cost.And indivedual tuyere medium sleeve usage times can be again less than 1 year
It is secondary nose, leakage gas occur.Frequently change, increase pig iron cost, increase blast-furnace man's labor intensity.
Utility model content
The purpose of this utility model is in a kind of closure dress for handling the big or middle set faying face gas leak of blast-furnace tuyere of offer
Put, its is rational in infrastructure, can effectively block blast furnace gas leakage, substantially reduce blast fumance scene gas concentration, lift employee
And enterprise safety operation, it can avoid, because changing tuyere medium sleeve, directly reducing producing cost, blast-furnace man's more air change outlet being reduced
Middle set labor intensity, improve worker's operating efficiency.
What the purpose of this utility model was realized in：A kind of big or middle set faying face gas leak of processing blast-furnace tuyere
The tuyere big sleeve and tuyere medium sleeve of mutual cooperation are installed on plugging device, including blast-furnace tuyere, it is big with air port in tuyere medium sleeve
Tuyere medium sleeve big end end face bottom at set cooperation, which coordinates, is installed with being made up of first, second curved plate of being fixed together
Baffle plate, ceramic asbestos packing and refractory seals are set wherein being set in the second curved plate lower end in the space of 45 ° of chamferings
Glue, on last furnace shell inwall by the bearing of setting it is affixed tuyere small sleeve pin-lift arrangement, on tuyere small sleeve pin-lift arrangement
Affixed the push rod stretched into tuyere big sleeve, the other end of push rod are fixed on the first curved plate.
Principle of the present utility model is by using blast furnace periodical repair chance, implements to block using home-made contrivance：Utilize resistance to height
Warm sealant sealing, then blocked with ceramic asbestos packing, then fixed with self-control camber steel ring by welding, fastening bolt
Etc. a series of fixed camber steel ring methods of sealings, effectively block the big-and-middle set faying face gas leak in air port.
Main improvement content is as follows：
1）It is standby that corresponding curved plate is made with initial reference to circular arc width outside tuyere medium sleeve and radian.Steel plate thickness is about
20mm, first piece of curved plate outer arc edge cut groove at 45 ° using oxyacetylene metal-cutting, are easy to compress ceramic asbestos packing.
2）The uniform Φ 16mm ceramics asbestos packings for smearing refractory seals glue are tightly attached to the tuyere medium sleeve of nose again
Outer lower edge.
3）The curved plate for cutting groove at 45 ° by first piece tightly pushes down ceramic asbestos packing, by second piece of curved plate
Push down first piece of curved plate, it is ensured that sealing effectiveness.
4）Tuyere medium sleeve curved plate and tuyere small sleeve top are fixed on using two ∮ 32mm of suitable dimension steel pipe bifurcated
Between lever apparatus.
5）Above-mentioned two pieces of curved plate segmented weldings are fixed as one, one end of fixed steel pipe are welded on, by second
Block curved plate, the other end are welded on tuyere small sleeve pin-lift arrangement.
6）Refractory seals glue is uniformly smeared into machined surface outside tuyere small sleeve again, tuyere small sleeve is installed in place.
7）Refractory seals glue is finally uniformly smeared to the head arc machined surface of air-supply blowpipe, blowpipe is installed in place.
Main improvement effect：
1）Blast furnace gas leakage can be effectively blocked, blast fumance scene gas concentration is substantially reduced, utilizes employee and enterprise
Safety in production.
2）It can avoid, because changing tuyere medium sleeve, directly reducing producing cost.
3）Reduce blast-furnace man and change tuyere medium sleeve labor intensity.
The utility model is rational in infrastructure, realizes effectively closure blast furnace gas leakage, greatly reduces blast fumance scene
Gas concentration, employee and enterprise safety operation are improved, avoid because changing tuyere medium sleeve, directly reduce producing cost, reduce
Blast-furnace man changes tuyere medium sleeve labor intensity, improves worker's operating efficiency.
