Description
Technical field
The utility model is related to a kind of tuyere medium jacket of blast furnace protectiveness provisions for disengagement.
Background technology
When set breakage needs replacing middle set in occurring when being covered during blast furnace medium-capital overhauling is replaced or in production, make
Industry method is that pull rod is first selected to pull out middle set in a manner of hitting；If can not pull, method is burnt with regard to selection oxygen, by middle set scaling loss portion
After point, pull it.Both methods all can centered cover cause to damage, middle set is caused secondary can not to use, and the method
Need more labour（At least need 6-7 people）, consume more material（Oxygen lance, coke, oxygen）And the time（General 2-4 is small
When）, secondly as oxygen burns operation, the big set of scaling loss is easier to, causes the loss in terms of economy and manpower.
Invention content
In order to avoid the generation of above-mentioned various situations, the utility model, which is provided during one kind can be pulled out fully, to be covered, and may be used also
To reduce the tuyere medium jacket of blast furnace protectiveness provision for disengagement of the amount of labour.
The utility model solves the problems, such as the technical solution used：A kind of tuyere medium jacket of blast furnace protectiveness provision for disengagement, including
That is installed in furnace shell carries big set, the middle set of big set flange, covers be fixedly connected one by pin rod on the outer end face of flange greatly
Block circular pressing plate, sets a circular groove at the center of circular pressing plate, water respectively on the pressing plate plate body of circular groove both sides
It is flat to be symmetrical arranged a through-hole, a pull rod is installed in through-hole respectively, the inner end of pull rod is respectively provided with a barb, barb
It is in contact with the middle set inner side end, is positioned between two in middle set piece pull rod by gusset, keep two pull rods
Between spacing fix, the outside portion of two pull rods is set with from inside to outside sets top plate, gasket and nut, round recessed
One jack is set between slot and top plate.
After blast furnace staying EP (end of program), corresponding small set is pulled out, upper adhesive is covered in cleaning, is enable during pull rod hangs over
Cover bottom end；After pull rod passes through pressing plate, pressing plate is placed on big sleeve screw rod, is ensured steady；Top plate is passed through into pull rod, sets up pad
Piece, and nut is screwed on pull rod, the nut tightening of two pull rods makes pressing plate parallel with top plate to same position；Place jack
And it is made to be fixed between pressing plate and top plate；Gusset is placed in designated position, keeps the parallel of two pull rods；After installing, make
Middle set is ejected with jack.
This provision for disengagement is easy to operate, and a set of extracting tool can be reused for a long time, and each spare part is simple in structure, is easy to add
Work；After provision for disengagement is come into operation, intact pull-out can be covered by middle, so as to secondary use；This utility model reduces labor
Momentum, general 3-4 people can installation exercise, be installed to dismounting operation can generally be completed in 1.5 hours.
Description of the drawings
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is the main structure diagram of the utility model.
Specific embodiment
A kind of tuyere medium jacket of blast furnace protectiveness provision for disengagement, as shown in Figure 1, including being installed in furnace shell 5 with big set
Big set 9, the middle set 8 of flange 10, cover be fixedly connected one piece of circular pressing plate 4 by pin rod 11 on the outer end face of flange 10 greatly, circle
One circular groove is set at the center of shape pressing plate 4, and horizontal symmetrical is set respectively on the pressing plate plate body of circular groove both sides
One through-hole, is installed with a pull rod 6 in through-hole respectively, and the inner end of pull rod 6 is respectively provided with a barb, barb with it is described in
It covers 8 inner side ends to be in contact, be positioned between two pull rods in middle set 8 by gusset 7, between keeping between two pull rods
Away from fixation, the outside portion of two pull rods 6 is set with from inside to outside sets top plate 3, gasket 2 and nut 1, circular groove with
One jack 12 is set between top plate.During work, top plate 3 is ejected outward by jack 12, pull rod 6 is pulled to be covered in
8 pull out.
