Description

A kind of sinter cooler and adjustable dynamic sealing device

Technical field

The sealing device of cold bed chassis on sintering machine is the utility model is related to, more specifically to one kind sintering cooling Machine and adjustable dynamic sealing device.

Background technology

In steel production, sintering production is one of important process, and it provides high-quality raw material for blast furnace ironmaking.Sintering After completion, when cold bed chassis carries the directed movement in orbit of red-hot sintered clinker, bellows are upward in cold bed pallet bottom Air blast, cold wind pass through sinter bed, cool down sintering feed, and itself is delivered in waste heat boiler by petticoat pipe after being heated and generated electricity, The sensible heat in sinter bed is reclaimed in this approach, improves efficiency of energy utilization.In order to improve hot blast temperature as far as possible, it is necessary to assure Have reliable sealing in sinter cooler between cold bed chassis and petticoat pipe, i.e., do not produce leak out or it is caused leak out it is as few as possible. It is the emphasis and difficult point of sintering process design and production maintenance to reduce sinter cooler and leak out, due to the cold bed chassis top of sinter cooler Gap be present between end and petticoat pipe bottom, leak out serious, sometimes even up to more than 50%, not only reduce Waste Heat Generation amount, Increase air blower power consumption, form noise pollution, and limit the raising of sintering production efficiency and influence product quality.

Sealing in traditional sinter cooler between cold bed chassis and petticoat pipe is all to use the fiber with some strength Plate, the side of fiberboard is fixed on petticoat pipe, sealing is realized using the dynamic friction between fiberboard and cold bed chassis top, But this linear sealing mode sealing effectiveness is relatively poor, and because fiberboard both sides circumstance of temperature difference is larger, by periodically Expand with heat and contract with cold, fiberboard self-strength decay, fiberboard after deforming reduces to cold bed chassis top pressure, between the two Gap it is increasing, air leak rate of air curtain incrementally increases；It is furthermore easy between adjacent cold bed chassis in orbit due to path wear Misplace, this dislocation can during cold bed trolley movement to cause fiberboard damage or even de- with fiberboard phase scratching Fall, cause air leak rate of air curtain to be significantly increased.

On the sealing device used on sinter cooler, Patents disclose in the prior art, as patent discloses Number：CN101368794A, publication date：On 2 18th, 2009, invention and created name was：Sintering machine, sinter cooler and its suspension Sealing device, this application case discloses a kind of power consumption for reducing blower fan, reduction equipment is leaked out, improves waste heat recovery efficiency, improves The sinter cooler and its suspension type water-tight equipment of environment；The sinter cooler of this application case includes：Load the more piece of sintering deposit Chassis；If quarrel high petticoat pipe on more piece chassis；Positioned at the bellows often saved under chassis, the slideway of bellows and corresponding platform The elastic slide plate sliding contact of car；The suspension type sealing dress being mounted between the adjacent petticoat pipe of every two section on more piece chassis Put；Wherein, the upper end of suspension type sealing device is suspended on the joint portion of two adjacent petticoat pipes, and lower end is dangled on chassis is loaded in On sintering deposit.But this application case is disadvantageous in that：(1) suspension type sealing means sealing position therein is two adjacent The joint portion of petticoat pipe, to prevent from laterally altering the static seal of wind, function only as the effect of two adjacent petticoat pipes of static isolation, Wu Fashi For the dynamic sealing between cold bed chassis and petticoat pipe；(2) flexible sealing mode therein is sealed by the effect of blast, when When larger fluctuation occurs in blast, easily leak, the stability of sealing is not high.

In summary, the problem of sealing effectiveness is poor between existing cold bed chassis and petticoat pipe how is overcome, there is provided Yi Zhongan Dress is convenient, the dynamic sealing device of good sealing effect, is the technical problem of urgent need to resolve in the prior art.
