Abstract
The utility model discloses an airbag-type cover sealing device of a large pit furnace. The airbag-type cover sealing device for sealing a furnace body and a furnace cover comprises a ceramic fiber sealing ring, a furnace cover sealing ring plate, a pressure-adjustable charging airbag, and a circulating water cooling cavity, wherein the furnace cover sealing ring plate is arranged above the ceramic fiber sealing ring; the upper end of the furnace cover sealing ring plate is connected with a furnace cover; the pressure-adjustable charging airbag below the ceramic fiber sealing ring is arranged in a sealing groove of the furnace body; and the circulating water cooling cavity below the pressure-adjustable charging airbag is arranged on the inner side of the furnace body close to the sealing groove, and is connected with the furnace body. The pressure-adjustable charging airbag below the ceramic fiber sealing ring can provide a pressing force between the ceramic fiber sealing ring and the pressure-adjustable charging airbag and between the furnace cover sealing ring plate and the furnace body sealing surface so as to ensure good airtightness. Meanwhile, the large-diameter furnace body sealing surface obviates mechanical processing, thereby reducing the manufacture cost. The airbag-type cover sealing device has the advantages of safe and reliable sealing.
Description
Technical field
The utility model is about a kind of sealing device, more particularly, and about a kind of large-scale shaft furnace bell bellows seal device.
Background technology
At present, shaft furnace generally all adopts ceramic fibre sealing ring or falope to carry out the bell sealing.When the diameter of shaft furnace was big, the machining expense of sealing surface was relatively more expensive; Simultaneously, because ceramic fibre self under reusable situation, is difficult for compressing, cause leakage, poor sealing performance easily; And ring of silicone rubber,sealing is at high temperature lacked service life, the use cost height.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of large-scale shaft furnace bell bellows seal device, can not only under hot conditions, use, and good seal, cost is lower, can remedy deficiency of the prior art.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of large-scale shaft furnace bell bellows seal device; The described bellows seal device that seals between body of heater and the bell of being used for includes the ceramic fibre sealing ring, but also includes bell sealing ring flat-plate pressure regulation aerated capsule and circulating water-cooled cavity; Described bell sealing ring flat-plate is arranged on the top of described ceramic fibre sealing ring, and the upper end of described bell sealing ring flat-plate is connected with described bell; But the described pressure regulation aerated capsule that is positioned at ceramic fibre sealing ring below is arranged on the seal groove of described body of heater; But the described circulating water-cooled cavity that is positioned at pressure regulation aerated capsule below is arranged on the inboard of seal groove near body of heater; Described circulating water-cooled cavity is connected with body of heater.
But described pressure regulation aerated capsule includes ring-type utricule and inflation inlet.
Beneficial effect after the employing technique scheme is: large-scale shaft furnace bell bellows seal device of the present utility model, but the design of increase pressure regulation aerated capsule below the ceramic fibre sealing ring, but guarantee the thrust of ceramic fibre sealing ring and pressure regulation aerated capsule and bell sealing ring flat-plate and furnace sealing face at any time, guarantee good seal; Simultaneously, large diameter furnace sealing face can no longer carry out machining, has reduced cost of manufacture; Sealingly secure is reliable, long service life; Significantly reduced the blowing out loss that is caused because of the bell seal failure.
Description of drawings
Fig. 1 is that the medium-and-large-sized shaft furnace bell of the utility model bellows seal device is installed in the structural representation on the shaft furnace;
Fig. 2 is the A portion enlarged diagram of Fig. 1, and this there is shown the composition and the structure of bellows seal device;
But Fig. 3 is the structural representation of the pressure regulation aerated capsule of the medium-and-large-sized shaft furnace bell of the utility model bellows seal device;
Fig. 4 is along the cross-sectional schematic of B-B direction among Fig. 3.
Wherein, 1 body of heater, 2 bells (part) but, 3 bellows seal devices, 31 bells sealing ring flat-plate, 32 ceramic fibre sealing rings, 33 pressure regulation aerated capsules, 331 utricules, 332 inflation inlets, 34 circulating water-cooled cavitys.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment in the utility model is described in further detail.
As shown in Figures 1 and 2, large-scale shaft furnace bell bellows seal device of the present utility model, the described bellows seal device 3 that is used for sealing between body of heater 1 and the bell 2 includes ceramic fibre sealing ring 32; But also include bell sealing ring flat-plate 31 pressure regulation aerated capsules 33 and circulating water-cooled cavity 34; Bell sealing ring flat-plate 31 is arranged on the top of ceramic fibre sealing ring 32, and the upper end of bell sealing ring flat-plate 31 is connected with bell 2; But the pressure regulation aerated capsule 33 that is positioned at ceramic fibre sealing ring 32 belows is arranged on the seal groove of body of heater 1; But the circulating water-cooled cavity 34 that is positioned at pressure regulation aerated capsule 33 belows is arranged on the inboard of seal groove near body of heater 1; Circulating water-cooled cavity 34 is connected with body of heater 1.
But pressure regulation aerated capsule 33 includes ring-type utricule 331 and inflation inlet 332, as shown in Figures 3 and 4.
Large-scale shaft furnace bell bellows seal device of the present utility model in use, after bell 2 covers and also fixes on the body of heater 1, but aerating device begins to charge into gas by inflation inlet 332 to pressure regulation aerated capsule 33 with setting pressure, but pressure regulation aerated capsule 33 begins to expand, and ceramic fibre sealing ring 32 is pressed on the lower end sealing surface of bell sealing ring flat-plate 31, after arriving setting the blowing pressure value, finish inflation, reach the excellent sealing state.But circulating water-cooled cavity 34 can guarantee pressure regulation aerated capsule 33 and work under lower temperature, to prolong the service life of aerated capsule.
In the course of work, aerating device can be added inflation by setting pressure at any time according to the pressure changing in the utricule 331, guarantees that sealing load remains in the setting range for a long time, thereby guarantees that sealing is steady in a long-term, reliable.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
