Description
Technical field
A kind of the invention belongs to agglomerating plant field in iron and steel metallurgical industry, more particularly, it relates to sinter cooler
And its dynamic sealing equipment.
Background technology
In iron and steel produces, SINTERING PRODUCTION is one of important operation, and it provides the raw material of high-quality for blast furnace ironmaking.Sintering
After completing, when cold bed chassis carries red-hot sintered clinker directed movement in orbit, bellows are in cold bed pallet bottom upwards
Air blast, cold wind, through sinter bed, cools down sintering feed, is delivered in waste heat boiler by petticoat pipe and generated electricity after itself is heated,
Reclaim the sensible heat in sinter bed in this approach, improve 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, do not produce leaking out of leaking out or produce as few as possible.
Reduce sinter cooler to leak out is emphasis and the difficult point of sintering process design and production maintenance, due to the cold bed chassis top of sinter cooler
There is gap between end and petticoat pipe bottom, leak out serious, sometimes even reach more than 50%, not only reduce Waste Heat Generation amount,
Increase aerator power consumption, form sound pollution, and limit raising and the impact product quality of SINTERING PRODUCTION efficiency.
In traditional sinter cooler, the sealing between cold bed chassis and petticoat pipe is all using the fiber with some strength
Plate, the side of fibre board is fixed on petticoat pipe, realizes sealing using the dynamic friction between fibre board and cold bed chassis top,
But this linear sealing mode sealing effectiveness is relatively poor, and because fibre board both sides circumstance of temperature difference is larger, through periodically
Expand with heat and contract with cold, fibre board self-strength decay, the fibre board after deformation to cold bed chassis top pressure reduce, between the two
Gap increasing, air leak rate of air curtain incrementally increases；Furthermore due to path wear, between adjacent cold bed chassis in orbit easily
Dislocation occurs, this dislocation causes fibre board to damage or even de- with fibre board phase scratching during making cold bed trolley movement
Fall, lead to air leak rate of air curtain to be significantly increased.
With regard to the sealing device used on sinter cooler, in prior art, existing Patents are open, and such as patent is open
Number：CN 101368794 A, publication date：On 2 18th, 2009, invention and created name was：Sintering machine, sinter cooler and its outstanding
Hang sealing device, this application case discloses a kind of power consumption reducing blower fan, minimizing equipment leaks out, improves waste heat recovery efficiency, changes
The sinter cooler of kind environment and its suspension type water-tight equipment；The sinter cooler of this application case includes：Load the many of sintering deposit
Section chassis；If quarreling high petticoat pipe on more piece chassis；Be located at the bellows under every section chassis, the slideway of bellows with corresponding
The elastic slide plate sliding contact of chassis；It is mounted on more piece chassis every two and save the suspension type sealing between adjacent petticoat pipe
Device；Wherein, the upper end of suspension type sealing device is suspended on the joint portion of two adjacent petticoat pipes, 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, for preventing from laterally altering the static seal of wind, function only as the effect of two adjacent petticoat pipes of static isolation it is impossible to
It is applied to the dynamic sealing between cold bed chassis and petticoat pipe；(2) flexible sealing mode therein relies on the effect of blast to be sealed,
When larger fluctuation in blast, leakage easily occurs, the stability of sealing is not high.
In sum, how to improve the sealing effectiveness between cold bed chassis and petticoat pipe, be urgent need to resolve in prior art
Technical barrier.
