Description
Technical field
The invention belongs to sintering machine technical field of sealing technology, more particularly, to one kind from deashing sintering machine head end tail sealing device.
Background technique
Head-tail sealing is that sintering owner takes out system important component, and effect is closing pallet in into or out sintering stage
Locate the rectangular aperture of pallet bottom and bellows top, it is installed on the both ends of sintering machine wind box system, immediately head-tail star gear, fixed
In No.1 bellows and tail bellows two sides, by can automatic paste tightening trolley bottom surface several pieces of independent cover boards abutted side by side and
Front and back sealing plate prevents ambient air from entering main pumping system, so that bellows are in the subnormal ambient of about 5000Pa, guarantees that sintering is taken out at bottom
Suitable working condition.
Due to sintering machine system leak out it is a little more, reduce system air leakage rate can play a dual role of energy conservation and increase production,
And above-mentioned position air leak rate of air curtain accounts for system air leakage rate nearly 20%~30% or so, so head-tail sealing performance is also in the field of business great
Sustained improvement is able under concern, at present, a small amount of large-type sinterer and number small sintering machine big absolutely use spring jacking cover board
Structure type, and most large-type sinterer uses parallel four-bar linkage, improves anyway, generally belong to this two
The citation form of kind end seal.
The characteristics of citation form of both the above end seal: the spring jacking covering plate structure defect of the first form is bright
Aobvious, jacking spring is located under cover board and is close to installation, and spring metal is in elasticity under 400 ° or more continuous high temperature environment and degenerates
Quickly, so that losing the effect of top tight sealing cover board, air leak rate of air curtain gradually rebounds end to end；The parallel―ordinal shift machine of second of form
Structure, because adding counterweight balance to realize that stable cover board top power makes the larger improvement of sealing effect using double leval jib, service life is obtained
To extend, but common fault is equally obvious: 1. mechanisms are huge, and clump weight is more and again, and it is limited serious that clump weight adds and subtracts operating space.2.
Joint requirement on machining accuracy to activity linear sealing is harsh, and geometric tolerance is difficult to guarantee, and in-site installation is difficult to adjust benefit again when aligning
It repays, easily causes leverage Caton.3. above two structure common fault is that deashing has some setbacks, the lime-ash of access mechanism cabinet due to cannot and
When exclude and accumulate, and then jacking spring gap is filled, or retardance clump weight is freely lifted, the result is that seal cover board effect mistake
Effect.
