Description
Technical field
The utility model belongs to high furnace accessory technical field, and in particular to covers in a kind of new type BF tuyere.
Background technique
Blast-furnace tuyere is on Iron Works, and high-temperature hot-air and furnace bottom the char oxidation burning be blown by blast-furnace tuyere is given birth to
At CO, CO is restored originally in high temperature rising with iron existing for oxide form.
Tuyere medium sleeve plays particularly important effect on blast furnace, the quality strong influence of tuyere medium sleeve it is high
The safety and production yields that furnace uses, used tuyere medium sleeve cooling system mostly uses greatly an annular empty currently on the market
Chamber carry out it is cooling follow bad, cause cooling effect poor, while tuyere medium sleeve will receive extruding in use, be easy to produce change
Shape, and then tuyere medium sleeve is damaged, the service life of tuyere medium sleeve is largely effected on, is unfavorable for improving furnace processor and guarantee
The safety of blast fumance.
Utility model content
To solve the problems mentioned above in the background art.The utility model provides to be covered in a kind of new type BF tuyere,
Have the characteristics that good cooling performance, long service life and is unlikely to deform.
To achieve the above object, the utility model provides the following technical solutions: covering in a kind of new type BF tuyere, including set
Tin, inlet and outlet are opened up on the sleeve, the bottom of the water inlet is communicated with the first cavity, first cavity
Side is communicated with the second cavity, and the side of first cavity and the second cavity inner wall is fixedly connected to several deflectors,
First cavity is connected with water valve out, and the discharge outlet of second cavity is connected with the first cavity.
Preferably, the shape of first cavity and the second cavity is annular.
Preferably, the sleeve is fine copper forging.
Preferably, the deflector is cross-distribution, and the deflector is stainless steel plate.
Compared with prior art, the utility model has the beneficial effects that
1, the utility model uses the first cavity and the second cavity by setting, can be to the inside and outside same of sleeve
Shi Jinhang is cooling, and support can be played the role of to sleeve, strengthen by improving cooling efficiency and cooling effect, several deflectors
The integral rigidity of sleeve, prevents colleting deformation, which uses the first cavity, the second cavity and deflector, substantially increases set
The cooling effect of cylinder, strengthens the rigidity of sleeve, greatly avoids the problem that colleting deformation, and ensured sleeve significantly uses the longevity
Life, whole device is structurally reasonable, easy to use, practical.
2, the utility model, by be arranged water inlet facilitate water enter in the first cavity and the second cavity carry out water follow it is bad,
Water outlet facilitates water to be discharged, and sleeve material is fine copper forging, and copper has good heating conduction and corrosion resistance, can reduce height
Damage of the furnace high temperature to sleeve, ensures the service life of sleeve.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the structural schematic diagram that the utility model faces section；
Fig. 2 is the structural schematic diagram that the utility model is overlooked；
In figure: 1, sleeve；2, the first cavity；3, deflector；4, water inlet；5, the second cavity；6, water outlet.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1
The utility model in a kind of new type BF tuyere the following technical schemes are provided: cover referring to FIG. 1-2, including sleeve
1, open up water inlet 4 and water outlet 6 on the sleeve 1, water inlet 4 facilitates water to enter in the first cavity 2 and the second cavity 5 to carry out
Water follows bad, and water outlet 6 facilitates water to be discharged, and the sleeve 1 is fine copper forging, and copper has good heating conduction and corrosion resistance,
Damage of the blast furnace high temperature to sleeve 1 can be reduced, ensures the service life of sleeve 1, the bottom of the water inlet 4 is communicated with first
Cavity 2, the side of first cavity 2 are communicated with the second cavity 5, can be to sleeve 1 using the first cavity 2 and the second cavity 5
It is inside and outside and meanwhile cooled down, improve cooling efficiency and cooling effect, the shape of first cavity 2 and the second cavity 5
Shape is annular, and the side of 5 inner wall of first cavity 2 and the second cavity is fixedly connected to several deflectors 3, several
Deflector 3 can play the role of support to sleeve 1, strengthen the integral rigidity of sleeve 1, prevent sleeve 1 from deforming, the water conservancy diversion
Plate 3 is cross-distribution, and the deflector 3 is stainless steel plate, and first cavity 2 is connected with water outlet 6, second cavity
5 discharge outlet is connected with the first cavity 2, which uses the first cavity 2, the second cavity 5 and deflector 3, substantially increases
