It is very short with the life-span, usual rubber slab run 3 months will aging it is damaged, air leak rate of air curtain is up to 30%- between damaged rear chassis and petticoat pipe
40%, sintering process effects of energy saving and emission reduction is influenceed, after rubber slab damage, need to stop production to change, therefore can destroy sintering production
Continuity, influences sintering machine production efficiency.
The content of the invention
It is an object of the invention to provide the sealing device between a kind of sintering device flue gas circulation cover and chassis, it can burn
Knot machine, which is circulated, forms effectively sealing between petticoat pipe and chassis, it is ensured that the effects of energy saving and emission reduction of sintering process, and can keep for a long time
Good sealing property, will not produce influence to the continuity of sintering production.
The present invention to achieve the above object, is achieved through the following technical solutions：Including chassis, chassis both sides set breast board,
Installed on the outside of breast board and flanging, flanging and horizontal plane, the length direction of flanging are set on the outside of lower sealing supporting plate, lower sealing supporting plate
Parallel with the length direction of breast board, flanging sets Internal baffle close to the side of breast board, and side of the flanging away from breast board sets outer keep off
It is connected at the top of plate, Internal baffle and outer baffle with connecting plate, connecting plate circulates petticoat pipe by connector and sintering machine and is connected.Sintering
Machine circulation petticoat pipe outer wall sets multiple plates, and connecting plate position corresponding with each plate opens up jack, and plate is passed through out of jack,
Opened up on plate and chock is installed in through hole, through hole.Connecting plate bottom sets transverse slat, and transverse slat is mutually perpendicular to connecting plate, Internal baffle
It is connected respectively with transverse slat with outer baffle top.Reinforcement is set between adjacent through-holes, and reinforcement connects with connecting plate and transverse slat respectively
Connect.Outer baffle bottom sets lower baffle plate, and lower baffle plate is located at below flanging.Elasticity is set between connecting plate and sintering machine circulation petticoat pipe
Sealing gasket.The elastic sealing gasket is asbestos pad.
The advantage of the invention is that：Service life is longer, is not required to stop production and sealing structure is changed, can by chassis and
Air leak rate of air curtain between petticoat pipe is down to less than 10%, it is ensured that the effects of energy saving and emission reduction of sintering process, close with the progress of sintering production
Envelope effect can progressively strengthen on the original basis, can ensure long-term continuous and steady operation of sintering process etc..
Brief description of the drawings

Fig. 2 is Fig. 1 A to mplifying structure schematic diagram.
Embodiment
A kind of sealing device between sintering device flue gas circulation cover and chassis of the present invention includes chassis 1,1 liang of chassis
Side sets breast board 2, and lower sealing supporting plate 3 is installed in the outside of breast board 2, and the lower outside of sealing supporting plate 3 sets flanging 4, and flanging 4 hangs down with horizontal plane
Directly, the length direction of flanging 4 is parallel with the length direction of breast board 2, and flanging 4 sets Internal baffle 5, flanging 4 close to the side of breast board 2
Side away from breast board 2 sets outer baffle 6, and Internal baffle 5 and the top of outer baffle 6 are connected with connecting plate 7, and connecting plate 7 passes through even
Fitting is connected with sintering machine circulation petticoat pipe 8.The present invention forms labyrinth seal structure by Internal baffle 5, outer baffle 6 and flanging 4,
This sealing structure will not aging, service life is longer, is not required to stop production and sealing structure is changed, can be by chassis and petticoat pipe
Between air leak rate of air curtain be down to less than 10%, it is ensured that the effects of energy saving and emission reduction of sintering process, lower sealing supporting plate 3 can collect sintering cigarette
Spreading during particulate matter and sintering machine distributing that gas tape loop comes, makes this partial particulate thing and spreading be deposited in labyrinth type
The porch of sealing structure, further enhances sealing effectiveness, therefore with the progress of sintering production, sealing effectiveness meeting of the invention
Progressively strengthen on the original basis, the long-term continuous and steady operation of sintering process can be ensured.
Connector between connecting plate 7 and sintering machine circulation petticoat pipe 8 of the present invention is preferred to use following structures：Sintering machine
Circulate petticoat pipe 8 outer wall and multiple plates 9 are set, connecting plate 7 and the corresponding position of each plate 9 open up jack 10, plate 9 is from jack 10
Inside pass through, opened up on plate 9 and chock 12 is installed in through hole 11, through hole 11.The structure is remained to after having easy for installation, temperature distortion
Easy removal and the advantage reused.In addition, the connector between connecting plate 7 of the present invention and sintering machine circulation petticoat pipe 8
Can also be using other various structures such as bolt, but these structure installation operations are relatively complicated, and be difficult to after temperature distortion to tear open
Unload and reuse.
The present invention can set transverse slat to prevent flanging 4 from being rubbed with Internal baffle 5 and outer baffle 6 in the bottom of connecting plate 7
13, transverse slat 13 is mutually perpendicular to connecting plate 7, and Internal baffle 5 and the top of outer baffle 6 are connected with transverse slat 13 respectively.The structure can be protected
Demonstrate,prove Internal baffle 5 and outer baffle 6 is parallel with flanging 4, flanging 4 will not rub with Internal baffle 5 and outer baffle 6 during chassis slight shift
Wipe.
The present invention makes between connecting plate 7 and sintering machine circulation petticoat pipe 8 to prevent from producing flexural deformation after connecting plate 7 is heated
There is gap, reinforcement 14 can be set between adjacent through-holes 11, and reinforcement 14 is connected with connecting plate 7 and transverse slat 13 respectively.By
Fixed in connecting plate 7 in through hole by chock 12, thus connecting plate 7 it is heated after can be between adjacent through-holes 11 position become
Shape, the position can effectively lift the resistance to deformation intensity of connecting plate 7 after setting reinforcement 14, prevent connecting plate 7 from being followed with sintering machine
There is gap between ring petticoat pipe 8.The structure increases the thickness of connecting plate 7 with entirety or the reinforcement of entirety is set on connecting plate 7
