Abstract
The utility model discloses a sealing device for an end part of a cold machine smoke hood of a sintered ring. The sealing device comprises a hinged temperature-resistant elastic sealing curtain (2) arranged on the smoke hood (1), wherein weight blocks (3) are respectively fixed at the lower end of the hinged temperature-resistant elastic sealing curtain (2) along horizontal and vertical directions. By arranging the flexible hinged temperature-resistant elastic sealing curtain, the sealing device for the smoke hood of the sinter ring cold machine greatly reduces the air leakage rate of the end of the smoke hood of the sintered ring cold machine, prolongs the service life of the hinged temperature-resistant elastic sealing curtain, has simple structure and is convenient for installation and repair.
Description
Technical field
The utility model relates to the sealing device of a kind of sintering circular-cooler petticoat pipe end.
Background technology
It is one of emphasis of present steel industry energy-saving and emission-reduction that the fume afterheat of sintering cooling procedure is recycled.Wherein, respectively the leak out actual sealing effectiveness at position of central cooler system is again the key factor of decision heat recovery effect.In the position of respectively leaking out of central cooler residual neat recovering system, the petticoat pipe end is again the most serious one of leaks out a little.Simultaneously, the actual conditions of sintering deposit central cooler process for cooling have determined the petticoat pipe end to be difficult to realize sealing completely again.In the existing engineering, some clear-cut just employing of ring cold machine smoke hood end seals, and some only is to adopt several simple hinge turnover panels to seal.Because the material on chassis surface is not fully smooth, the lifting simultaneously of adjacent hinge turnover panel must make between the adjacent hinge turnover panel and produce certain included angle, and then cause leaking out of angle.And, because employed hinge turnover panel limited amount (generally being no more than 6), the length of every hinge turnover panel is longer, to such an extent as to even the projection of a certain block of sintering deposit in chassis surface all can make contacted monoblock hinge turnover panel upwards dig, and finally produced leaking out on the monoblock hinge turnover panel length, had a strong impact on the effect of waste heat recovery.
The utility model content
The purpose of this utility model is to provide a kind of sealing device of simple in structure, sintering circular-cooler petticoat pipe end that air leak rate of air curtain is low.
The purpose of this utility model is to be achieved through the following technical solutions.
The sealing device of a kind of sintering circular-cooler petticoat pipe end, it is characterized in that: described sealing device comprises the hinge type heatproof elastic packing curtain that is arranged on the petticoat pipe, all is fixed with gravity block on the lower end edge level of described hinge type heatproof elastic packing curtain and vertical direction.
Gravity block on the described hinge type heatproof elastic packing curtain lower end edge horizontal direction is more than two, and the slit between the adjacent gravity block is greater than 5mm.
Gravity block on the described hinge type heatproof elastic packing curtain lower end edge vertical direction is more than two, and the slit between the adjacent gravity block is greater than 5mm.
Described gravity block is arranged at a side of hinge type heatproof elastic packing curtain contact sintering deposit.
As a kind of preferred, in order to improve the rub proofness of gravity block, described gravity block is the antifriction metal (AFM) piece.
The utility model greatly reduces the air leak rate of air curtain of finishing the ring cold machine smoke hood end by the setting of flexible hinge formula heatproof elastic packing curtain.The setting of antifriction metal (AFM) piece has prolonged hinge type heatproof elastic packing curtain service life.Simple in structure, installation, maintenance is convenient.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the left view of Fig. 1;
Among the figure, part 1 is a petticoat pipe, and part 2 is a hinge type heatproof elastic packing curtain, and part 3 is a gravity block.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.
As depicted in figs. 1 and 2, the sealing device of a kind of sintering circular-cooler petticoat pipe end comprises the hinge type heatproof elastic packing curtain 2 that is arranged on the petticoat pipe 1, and described gravity block 3 is arranged at a side of hinge type heatproof elastic packing curtain 2 contact sintering deposits.On the lower end edge level of described hinge type heatproof elastic packing curtain 2 and vertical direction, all be fixed with gravity block 3.Gravity block on the described hinge type heatproof elastic packing curtain 2 lower end edge horizontal directions is 7, leaves the slit greater than 5mm between the adjacent gravity block.Gravity block on the hinge type heatproof elastic packing curtain 2 lower end edge vertical direction is two, leaves the slit greater than 5mm between the adjacent gravity block.Certainly, also can adjust according to actual needs on the horizontal direction and vertical direction on gravity block.Wherein gravity block can be the antifriction metal (AFM) piece, in the service life that can improve gravity block like this, guarantees sealing effectiveness.Certainly, gravity block also can be selected some common metal derbies, wear-resisting nonmetal or not wear-resisting nonmetal.
During work, whole hinge type heatproof elastic packing curtain vertically drops on the sintering deposit.When running into the sintering deposit of projection, the hinge type heatproof elastic packing curtain that sintering deposit is run into lifts along with the close gradually of sintering deposit bossing.Along with sintering deposit constantly moves forward, the peak of sintering deposit bossing will be crossed hinge type heatproof elastic packing curtain, at this moment, the hinge type heatproof elastic packing curtain that contacts with sintering deposit again can along with the sintering deposit bossing gradually away from and fall, and finally return to plumbness.Because hinge type heatproof elastic packing curtain is flexible, the projection sintering deposit only is confined to the place that closely contacts with sintering deposit to the influence of hinge type heatproof elastic packing curtain, the process that whole hinge type heatproof elastic packing curtain rises and falls can be similar to is pasting sintering deposit and is carrying out, the bag property tied up is better, has played the better seal effect.
