Description
Present patent application is for application No. is 2016110700485 divisional application, the applyings date of original application
Are as follows: 2016-11-29, invention and created name are as follows: a kind of sinter cooler and its dynamic sealing equipment.
Technical field
The invention belongs to the agglomerating plant fields in iron and steel metallurgical industry, more specifically to a kind of sinter cooler.
Background technique
In steel production, sintering production is important one of process, it provides good raw material for blast furnace ironmaking.Sintering
After completion, when cold bed trolley 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, and cooling sintering feed is sent by petticoat pipe after itself being heated and generated electricity into waste heat boiler,
The sensible heat in sinter bed is recycled 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 trolley and petticoat pipe, i.e., does not generate and leak out or leaking out of generating is as few as possible.
Reducing sinter cooler and leaking out is the key points and difficulties of sintering process design and production maintenance, due to the cold bed trolley top of sinter cooler
There are gap between end and petticoat pipe bottom, leak out serious, sometimes even up to 50% or more, not only reduce Waste Heat Generation amount,
Increase air blower power consumption, form noise pollution, and limits the raising of sintering production efficiency and influence product quality.
Sealing in traditional sinter cooler between cold bed trolley and petticoat pipe is all using the fiber with some strength
The side of fiberboard is fixed on petticoat pipe by plate, and sealing is realized using the dynamic friction between fiberboard and cold bed trolley top,
But this linear sealing mode sealing effect is relatively poor, and since fiberboard two sides circumstance of temperature difference is larger, by periodicity
Expand with heat and contract with cold, fiberboard self-strength decaying, fiberboard after deforming reduces cold bed trolley top pressure, between the two
Gap it is increasing, air leak rate of air curtain incrementally increases；Furthermore due to path wear, it is easy between adjacent cold bed trolley in orbit
It misplaces, this dislocation meeting with fiberboard phase scraping collision during cold bed trolley movement so that cause fiberboard damage even de-
It falls, air leak rate of air curtain is caused to be significantly increased.
About the sealing device used on sinter cooler, has related patents in the prior art and disclose, such as patent disclosure
Number: 101368794 A of CN, publication date: on 2 18th, 2009, invention and created name are as follows: sintering machine, sinter cooler and its outstanding
Sealing device is hung, this application discloses a kind of power consumption for reducing blower, reduction equipment to leak out, improves waste heat recovery efficiency, changes
The sinter cooler and its suspension type water-tight equipment of kind environment；The sinter cooler of this application includes: the more of loading sinter
Save trolley；If quarreling high petticoat pipe on more piece trolley；Bellows under every section trolley, the slideway of bellows and corresponding
The elastic slide plate sliding contact of trolley；The suspension type sealing being mounted between the adjacent petticoat pipe of every two section on more piece trolley
Device；Wherein, the upper end of suspension type sealing device is suspended on the engaging portion of two adjacent petticoat pipes, and lower end pendency is being loaded in trolley
On upper sinter.But this application is disadvantageous in that: (1) suspension type sealing means sealing position therein is two phases
The engaging portion of adjacent petticoat pipe functions only as the effect of two adjacent petticoat pipes of static isolation to prevent from laterally altering the static seal of wind, can not
Suitable for the dynamic sealing between cold bed trolley and petticoat pipe；(2) flexible sealing mode therein is sealed by the effect of wind pressure,
