Description
Technical field
The utility model belongs to the agglomerating plant field in iron and steel metallurgical industry, more specifically to sinter cooler
And its dynamic sealing equipment.
Background technology
In steel production, SINTERING PRODUCTION is one of important operation, and it provides the raw material of high-quality 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 cools down sintering feed by sinter bed, and itself is generated electricity in delivering to waste heat boiler by petticoat pipe after being heated,
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
There is reliable sealing in sinter cooler between cold bed chassis and petticoat pipe, i.e., do not produce that leaks out or produce to leak out 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
There is gap 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 raising and the influence product quality of SINTERING PRODUCTION efficiency.
Sealing in traditional sinter cooler between cold bed chassis and petticoat pipe is all using the fiber with some strength
Plate, the side of fiberboard is fixed on petticoat pipe, and 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 deformation reduces to cold bed chassis top pressure, between the two
Gap it is increasing, air leak rate of air curtain is incrementally increased；Furthermore due to path wear, between adjacent cold bed chassis in orbit easily
There is dislocation, this dislocation can cause to cause fiberboard to damage or even de- with fiberboard phase scratching during cold bed trolley movement
Fall, cause air leak rate of air curtain to be significantly increased.
On the sealing device used on sinter cooler, Patents are disclosed in the prior art, and such as patent is disclosed
Number：The A of CN 101368794, publication date：On 2 18th, 2009, invention and created name was：Sintering machine, sinter cooler and its outstanding
Sealing device is hung, this application case discloses a kind of power consumption for reducing blower fan, reduction equipment and leaks out, improve waste heat recovery efficiency, change
The sinter cooler and its suspension type water-tight equipment of kind environment；The sinter cooler of this application case includes：Load many of sintering deposit
Section chassis；If quarreling petticoat pipe high on more piece chassis；Positioned at often section chassis under bellows, the slideway of bellows with it is corresponding
The elastic slide plate sliding contact of chassis；It is mounted on the suspension type sealing between the adjacent petticoat pipe of every two section on more piece chassis
Device；Wherein, the upper end of suspension type sealing device is suspended on two joint portions of adjacent petticoat pipe, and lower end pendency is being loaded in chassis
On upper sintering deposit.But this application case is disadvantageous in that：(1) suspension type sealing means sealing position therein is two phases
The joint portion of adjacent petticoat pipe, to prevent from laterally altering the static seal of wind, functions only as two effects of adjacent petticoat pipe of static isolation, it is impossible to
Suitable for the dynamic sealing between cold bed chassis and petticoat pipe；(2) flexible sealing mode therein is sealed by the effect of blast,
When larger fluctuation occurs in blast, easily there is leakage, the stability of sealing is not high.
In sum, the sealing effectiveness between cold bed chassis and petticoat pipe how is improved, is urgent need to resolve in the prior art
Technical barrier.
