Description
Technical Field
The utility model relates to an iron-making device, in particular to a blast furnace tuyere structure.
Background
The active state in the tuyere area of the blast furnace plays a very important role in blast furnace smelting, and the reasonable initial gas flow distribution and the hearth thermal state are ensured, so that the blast furnace tuyere area is a basic condition for high yield and smooth operation of the blast furnace. The inner condition of the tuyere lens can be directly observed. Keeping the tuyere lens bright and ashless is a necessary link for maintaining blast furnace production. The lenses have dust deposition in daily production due to the influence of coal injection in the tuyere and the like, the observation of the tuyere area in the furnace is influenced, the lenses need to be replaced for several times in one day, each time one lens is replaced, and the operation area for replacing the lenses belongs to a coal gas area and is not suitable for long-term operation. One large and medium blast furnace has more than 30 air ports, namely more than 30 lenses, and the working time is long in a coal gas area due to large workload.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a blast furnace tuyere mirror structure, prolonging the service time of the blast furnace tuyere mirror.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a blast furnace tuyere mirror structure, tuyere mirror threaded connection is on the little lid threaded rod in wind gap, and the tuyere mirror includes lens lid, lens, deposition pad, is equipped with the peephole on the lens lid terminal surface, and the lens is covered and is equipped with the screw hole, and lens, deposition pad are placed in proper order to screw hole inside, and the deposition pad includes the ring body and the claw body of a body structure, and the claw body distributes along ring body excircle circumference, and the excircle diameter of the claw body is unanimous with the excircle diameter of lens, forms the deposition district between the claw body.
The dust deposition pad is made of aluminum alloy.
The number of the claw bodies is 3-5.
The thickness of the dust deposition pad is 3mm-6 mm.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses be equipped with the deposition pad, prolong the live time of lens, reduce the work load of changing the lens, reduced the lens consumption, improve work efficiency.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
FIG. 2 is a schematic view of a dust mat.
In the figure: lens lid 1, lens 2, deposition pad 3, wind gap tegmen threaded rod 4, peephole 5, screw hole 6, ring body 31, claw body 32.
Detailed Description
The following further describes the embodiments of the present invention with reference to the attached drawings:
referring to fig. 1-2, the tuyere mirror structure is in threaded connection with a tuyere small cover threaded rod 4, and comprises a mirror cover 1, a mirror 2 and a dust deposition pad 3, wherein the dust deposition pad is made of an aluminum alloy material.
The end face of the lens cover 1 is provided with a peephole 5, a threaded hole 6 is arranged in the lens cover 1, the lens 2 and the dust deposition pad 3 are sequentially placed in the threaded hole 6, the dust deposition pad 3 comprises a ring body 31 and claw bodies 32 which are of an integral structure, the claw bodies 32 are distributed along the circumference of the outer circle of the ring body 31, and the number of the claw bodies is 3-5. The outer diameter of the claw bodies 32 is consistent with that of the lens 2, and dust accumulation areas are formed among the claw bodies 32. The thickness of the dust-collecting pad is 3mm-6 mm.
Examples
The utility model provides a blast furnace tuyere mirror structure, tuyere mirror threaded connection is on wind gap tegillum threaded rod 4, and the tuyere mirror includes lens lid 1, lens 2, deposition pad 3, and the deposition pad is the aluminum alloy material, and the thickness of deposition pad is 3 mm.
Be equipped with peephole 5 on the terminal surface of lens lid 1, be equipped with screw hole 6 in the lens lid 1, lens 2, deposition pad 3 are placed in proper order to screw hole 6 inside, and deposition pad 3 includes ring body 31 and the claw body 32 of a body structure, and 4 individual claw bodies 32 distribute along ring body 31 excircle circumference, and the excircle diameter of claw body 32 is unanimous with the excircle diameter of lens 2, forms the deposition district between the claw body 32.
When lens 2 when discovering the tuyere glass has the ash, rotate lens lid 1, let wind gap tegillum threaded rod 4 and lens lid 1 take place to become flexible, under the high-pressure gas's in the stove effect, the particle deposition in the tuyere glass just emits from lens lid 1 and wind gap tegillum threaded rod 4 within a definite time, and the deposition that the granule is big just persists on the deposition area of deposition pad 3, tighten lens lid 1 again. Therefore, the dust removing operation can be completed only by loosening the lens cover 1 and then screwing the lens cover down, the operation time in a gas area is rapidly shortened, the operation of replacing the lens 2 is omitted, the operation of replacing the lens 2 is carried out after the dust on the dust-collecting pad 3 is fully accumulated, the operation of replacing the lens for several times every day is changed into the operation of replacing the lens for once every two days, the working efficiency is improved, and the stay time in the gas area is shortened.
The above is only the basic principle of the present invention, not to the present invention makes any limitation, all the bases of the present invention are the same changes and modifications to the above, all within the scope of the protection scheme of the present patent technology.
