Fig. 1 is structural representation of the present invention;
Fig. 2 is that the A of Fig. 1 is to structure for amplifying schematic diagram.
Detailed description of the invention
Sealing device between a kind of sintering device flue gas circulation cover of the present invention and chassis comprises chassis 1, chassis 1 both sides arrange breast board 2, lower seal supporting plate 3 is installed outside breast board 2, lower seal supporting plate 3 arranged outside flanging 4, flanging 4 and horizontal plane, the length direction of flanging 4 is parallel with the length direction of breast board 2, flanging 4 arranges Internal baffle 5 near the side of breast board 2, flanging 4 arranges outer baffle 6 away from the side of breast board 2, Internal baffle 5 is all connected with connecting plate 7 with outer baffle 6 top, and connecting plate 7 is connected with sintering machine circulation petticoat pipe 8 by connector.The present invention is by Internal baffle 5, outer baffle 6 and flanging 4 form labyrinth seal structure, this hermetically-sealed construction can not be aging, service life is longer, do not need to stop production and hermetically-sealed construction is changed, air leak rate of air curtain between chassis and petticoat pipe can be down to less than 10%, ensure the effects of energy saving and emission reduction of sintering process, lower seal supporting plate 3 can collect the spreading that sinter fume circulates in the particle and sintering machine distributing process that bring, this part particle and spreading is made to be deposited in the porch of labyrinth seal structure, further enhancing sealing effectiveness, therefore along with the carrying out of SINTERING PRODUCTION, sealing effectiveness of the present invention can progressively strengthen on the original basis, the long-term continuous and steady operation of sintering process can be ensured.
Connector between connecting plate 7 of the present invention and sintering machine circulation petticoat pipe 8 preferably adopts following structure: sintering machine circulation petticoat pipe 8 outer wall arranges multiple plate 9, jack 10 is offered in the position that connecting plate 7 is corresponding with each plate 9, plate 9 passes in jack 10, plate 9 is offered through hole 11, in through hole 11, chock 12 is installed.This structure has after easy for installation, temperature distortion still can easy removal reusable advantage.In addition, the connector between connecting plate 7 of the present invention and sintering machine circulation petticoat pipe 8 also can adopt other various structures such as bolt, but the operation of these structure installment is comparatively loaded down with trivial details, and after temperature distortion, is difficult to dismounting and reuses.
The present invention rubs with Internal baffle 5 and outer baffle 6 for preventing flanging 4, and can arrange transverse slat 13 bottom connecting plate 7, transverse slat 13 is mutually vertical with connecting plate 7, and Internal baffle 5 is connected with transverse slat 13 respectively with outer baffle 6 top.This structure can ensure that Internal baffle 5 is parallel with flanging 4 with outer baffle 6, and during chassis slight shift, flanging 4 can not rub with Internal baffle 5 and outer baffle 6.
The present invention produces flexural deformation after preventing connecting plate 7 to be heated, and makes to occur gap between connecting plate 7 and sintering machine circulation petticoat pipe 8, and can arrange reinforcement 14 between adjacent through-holes 11, reinforcement 14 is connected with connecting plate 7 and transverse slat 13 respectively.Because connecting plate 7 is fixed by chock 12 in through hole, therefore connecting plate 7 can deform the position between adjacent through-holes 11 after being heated, effectively can promote the resistance to deformation intensity of connecting plate 7 after this position arranges reinforcement 14, prevent from occurring gap between connecting plate 7 and sintering machine circulation petticoat pipe 8.This structure and entirety increase the thickness of connecting plate 7 or arrange on connecting plate 7 compared with overall reinforcement structure, effectively can save material, and can reach identical resistance to deformation effect.
The present invention is for further to strengthen sealing effectiveness, and can arrange lower baffle plate 15 bottom outer baffle 6, lower baffle plate 15 is positioned at below flanging 4.Lower baffle plate 15 can increase the effusion difficulty of circulating flue gas further, and can realize taking in the particle of a small amount of effusion and spreading, is conducive to the dust pollution reducing on-site, keeps on-site environment clean and tidy.
The present invention seals the link position between connecting plate 7 and sintering machine circulation petticoat pipe 8 further, can arrange elastic sealing gasket 16 between connecting plate 7 and sintering machine circulation petticoat pipe 8.Elastic sealing gasket 16 compresses when being connected with sintering machine circulation petticoat pipe 8 by connecting plate 7, even if gap appears in the link position between connecting plate 7 and sintering machine circulation petticoat pipe 8, elastic sealing gasket 16 also can effectively prevent this place from occurring air leakage phenomena by the expansion of self.Described elastic sealing gasket 16 can adopt multiple material, such as rubber blanket etc., and wherein preferred version is: described elastic sealing gasket 16 is asbestos pads.Asbestos pad has heat-resisting and heat-insulating property is high, not easily aging advantage.
