Technical field

The invention belongs to blast furnace roof maintenance technology fields, and in particular to a kind of dust-proof knot for furnace top material tank for blast furnace Structure.

Background technique

Blast furnace process raw material by raw material system screening weigh after, using furnace top equipment material feeding jar, upper gate valve, on Close valve, blanking tank, material valve, under close valve, distributing device send to blast furnace, produced for blast furnace process, blanking tank is to weigh batch can, Material valve opens different apertures, so the weighing of blanking tank directly influences height according to different material weights and cloth feed ring number Cloth in furnace.With being constantly progressive for blast furnace smelting technology, modern blast furnace develops to directions such as large-scale, efficient, longevities, right Cloth precision requirement in furnace is higher and higher, and whether blanking tank weighs accurate, is directly related to the steady production of blast furnace.

It is upper gate valve and upper close valve between blast furnace roof material feeding jar and blanking tank, in order to not influence the weighing of blanking tank, on It uses and is flexible coupling between blanking tank, and have the fugitive dust generated in ventilating dust-arrester recycling blanking process.It has the following problems:

1, common bellows and buildup disk-form are used between upper and lower batch can, are flexible coupling and batch can gap because existing, are caused Fugitive dust bulk deposition will accumulate completely for two months or so on buildup disk in blanking process, and influence to weigh batch can weight, cause Feeding is abnormal, to influence the normal production of conditions of blast furnace and blast furnace；

2, when each blast furnace periodical repair, needs to arrange personnel and clear up dust stratification, at least need 3 talents that can complete, labor intensity Greatly, it also needs to arrange personnel sometimes temporarily to clear up, there are operating risks；

3, in each deashing process, it is be easy to cause fugitive dust situation, destory the scene environmental sanitation, increases the work of hand sweeping It measures.

Blast furnace on internal and international at present, be all using the connection type, and there are the problem of it is all unresolved, can only Carry out manual cleaning.

Summary of the invention

The purpose of the invention is to provide a kind of dustproof constructions for furnace top material tank for blast furnace, for preventing State of Blast Furnace The phenomenon that pushing up dust stratification between upper and lower batch can solves the problems, such as upper close clack box dust stratification in blanking process between upper and lower batch can.

For realize foregoing invention purpose, the technical solution adopted by the present invention is as follows:

The outside of a kind of dustproof construction for furnace top material tank for blast furnace, including buildup platform, the buildup platform uses ripple Pipe, bellows are externally connected with pipeline, and pipeline is communicated with compressed air, make to increase pressure in buildup platform by being passed through compressed air, Avoid dust stratification；Pipeline is equipped with hand-operated valve, solenoid valve and pressure interlocking switch, and the solenoid valve and pressure interlocking switch are with after The connection of platform system, when upper close valve is opened, background system controls solenoid valve and opens, and the inner wall of bellows is equipped with hardhead sponge, firmly Sponge is for preventing dirt material from entering inside, and the other side of hardhead sponge is equipped with soft sponge, and the other side of soft sponge is contacted with batch can.

Further, the pipeline is equipped with hand-operated valve, for using when emergency cut-off compressed air.

Further, the pressure interlocking switch, when being filled with compressed air, controlling pressure in buildup platform is 500pa- 600pa guarantees to prevent dust from entering, and will not over-voltage bellows is damaged.

Further, the hardhead sponge uses novel environment friendly plastics foamed material EVA.

Further, the hardhead sponge is at least divided into 3 pieces, each other by being bolted, when operating convenient for different zones more It changes, is bolted and avoids occurring gap between batch can, achieve the purpose that sealing.

Further, the soft sponge uses polyurethane.

Further, the soft sponge is muti-piece, is conveniently replaceable.

Compared with prior art:

The present invention adds product between the bellows and batch can that can prevent connecting between upper and lower batch can by dustproof construction Ash avoids the weighing for influencing blanking tank, guarantees the production of blast furnace stable smooth operation；It is pressurized simultaneously using compressed air, makes to be attached to sea Dust discharge on silk floss, reduces live deashing operation, realizes energy conservation and environmental protection.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below Example is not intended to limit the scope of the invention for illustrating the present invention.

As shown in connection with fig. 1, it includes buildup platform, feature that the present invention, which provides a kind of dustproof construction for furnace top material tank for blast furnace, It is, the outside of the buildup platform uses bellows 1, and bellows 1 is externally connected with pipeline 2, and pipeline 2 is communicated with compressed air, leads to It crosses and is passed through compressed air and makes to increase pressure in buildup platform, avoid dust stratification；Pipeline 2 is equipped with solenoid valve 3 and pressure interlocking switch 4, The solenoid valve 3 and pressure interlocking switch 4 are connect with background system, and when upper close valve is opened, background system control solenoid valve 3 is beaten It opens, the inner wall of bellows 1 is equipped with hardhead sponge 5, and the other side of hardhead sponge 5 is equipped with soft sponge 6, the other side of soft sponge 6 and batch can Contact.

Pipeline 2 is equipped with hand-operated valve 7, for using when emergency cut-off compressed air.When being filled with compressed air, pressure Interlocking switch 4 control buildup platform in compressed air pressure be 500kpa-600kpa, prevent dust from entering, and will not over-voltage to wave Line pipe 1 damages.

Hardhead sponge 5 is at least along being divided into 3 pieces, and each other by being bolted, hardhead sponge 5 uses novel environment friendly plastics foaming material Expect EVA, it is detachable and interchangeable when needing replacing.

Soft sponge 6 is muti-piece, fills the gap between full hardhead sponge 5 and batch can, and soft sponge 6 uses polyurethane, convenient for more It changes, avoids corroding.

In operation, when upper close valve is opened, background system controls solenoid valve 3 and opens, compressed air charged pressure Interlocking switch 4 guarantees compressed air pressure in 500pa-600pa, and the grit generated at this time descends slowly and lightly, due to the hard sea of dustproof construction Silk floss 5 obstructs, and avoids the case where grit is accumulated and needs replacing after dismountable connection type is convenient for long-time use When, hardhead sponge 5 can be replaced on demand, it is easy to operate, it is filled between hardhead sponge 5 and batch can by soft sponge 6, using polyurethane Equal acid resistant materials are filled as soft sponge 6, are prevented corrosion caused by coal gas etc. in operation, are guaranteed the resistance to of dustproof construction With property, due to being filled with for compressed air, the dust being accumulated in sponge can be discharged because of compressed air pressure, avoid dust stratification, Extend the service life of sponge.

The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited to This, anyone skilled in the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention And its inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
