Abstract

The utility model discloses a sealing device of a sinter cooler, which is capable of effectively reducing air leakage rate of the sinter cooler and comprises a sealing plate fixed on a cooling trolley and a sealing liquid groove fixed on a bellows below the cooling trolley. The sealing plate is disposed in liquid of the sealing liquid groove. The sealing device of the sinter cooler is obvious in energy saving effect. Limited by techniques and materials, air leakage rate of a cooler sealed by a traditional rubber plate is approximately 30% to 40%, and the maximum air leakage rate of the cooler adopting liquid sealing is not more than 10%. Taking a 415m2 recirculation cooler for an example, when the traditional technique is adopted, five cooling fans are needed for cooling, but when the liquid sealing technique is adopted, only four fans of the same types are capable of completely meeting requirements, and the sealing device of the sinter cooler saves electric energy by more than 20%.

Description

The sinter cooler sealing device

Technical field

The utility model relates to field of metallurgy, relates in particular to the sealing device on a kind of sinter cooler.

Background technology

Common sintering deposit temperature of being discharged by sintering machine must be cooled to them below 150 ℃ by cooler up to 700～800 ℃, could satisfy the operating temperature requirement of the adhesive tape conveyor and the cold ore deposit vibratory sieve of follow-up workshop section.Adopt traditionally by heat-resistant rubber slab friction sealed rotary forced-air cooler or straight line cooler and cool off.

As shown in Figure 1; Employing by the friction sealed cooler conventional seals method of heat-resistant rubber slab is: through being fixed in the mobile rubber slab 6 and the fixedly dynamic friction between the ash bucket 7 of cooling chassis 1 bottom; And be fixed in the fixedly rubber slab 8 on the ash bucket 7 and cool off the dynamic friction between chassis 1 bottom, common composition is double-deck friction sealed.

The shortcoming of traditional approach: the first, because of device fabrication or alignment error, and factor such as high temperature deformation in the equipment running process, can cause friction sealed gap inhomogeneous or enlarge, air leak rate of air curtain also increases; The second, rubber slab operation continuously under the condition of high temperature is for a long time followed the string because of aging, so sealing effectiveness variation gradually, and air leak rate of air curtain is increase thereupon also; Three, replacing sealed rubber plate labour intensity is big, expense is high, influence the number of working processes; Four, the dust of collecting in the ash bucket (bellows) must regularly unload ash by Double-deck cinder discharge valve 9, carries by the defeated grey car 10 of the track of special use again, so device structure and defeated ash handing system relative complex.

The utility model content

To the problems referred to above, the purpose of the utility model is to provide a kind of sinter cooler sealing device that can effectively reduce the sinter cooler air leak rate of air curtain.

For achieving the above object, the said a kind of sinter cooler sealing device of the utility model comprises the sealed liquid cell on the bellows that are fixed on the sealing plate on the cooling chassis and are fixed on said cooling chassis below, and said sealing plate places in the liquid of sealed liquid cell.

Preferably, said sealing plate is positioned at the both sides of said cooling chassis, respectively with the wheel homonymy that cools off on the chassis; Said sealed liquid cell is fixed on the both sides of said bellows gas outlet, and the position of sealed liquid cell is corresponding with sealing plate respectively.

Preferably, said sealed liquid cell is the seal groove of interior dress water.

Preferably, said cooling pallet bottom has the bulk cargo catch tray, and said bulk cargo catch tray places in the said bellows.

The beneficial effect of the utility model is:

1, energy-saving effect is obvious.Receive the restriction of technology and material, the cooler air leak rate of air curtain of traditional rubber slab sealing is generally 30%～40%, and the cooler air leak rate of air curtain maximum that adopts liquid to seal is no more than 10%.With the 415m2 central cooler for example, when adopting conventional art, need 5 cooling blower coolings,, only need 4 homotype blower fans just can meet the demands fully, save electric energy and surpass 20% if adopt the liquid Sealing Technology;

2, adopt the cooler of the utility model technology sealing, unload ash, ash conveying device because of having saved a cover, weight of equipment reduces, and the factory building absolute altitude reduces, so investment cost is also saved relatively;

3, because of need not to regularly replace sealing plate, so equipment operation rate also will improve.

Description of drawings

Fig. 1 is the sealing sketch map of prior art;

Fig. 2 is the sealing sketch map of the utility model.

The specific embodiment

Below in conjunction with Figure of description the utility model is done further description.

As shown in Figure 2; The said a kind of sinter cooler sealing device of the utility model embodiment; Comprise the sealed liquid cell 4 on the bellows 3 that are fixed on the sealing plate 2 on the cooling chassis 1 and are fixed on said cooling chassis 1 below, said sealing plate 2 places in the liquid of sealed liquid cell 4.

As the further embodiment of the utility model, because the cooling chassis is movably, bellows are fixed.So sealing plate 2 need be positioned at the both sides of said cooling chassis 1, respectively with the wheel homonymy that cools off on the chassis 1; Said sealed liquid cell 4 is fixed on the both sides of said bellows 3 gas outlets, and the position of sealed liquid cell 4 is corresponding with sealing plate 2 respectively, and assurance cooling chassis sealing plate at the volley places the liquid in the sealed liquid cell all the time, avoids gas leakage.

Wherein, said sealed liquid cell 4 is the seal groove of interior dress water.Because the water capacity is easy to get, and need not too many cost, the convenient use.Because bulk cargo drops in the course of work, is equipped with bulk cargo catch tray 5 in said cooling chassis 1 bottom, said bulk cargo catch tray 5 places in the said bellows, is used to collect bulk cargo, also can be transported to the emptying point with sintering deposit and together lay down.

The course of work: when the cooling chassis operation of sintering deposit 11 is housed; The sealing plate that is fixed on the bottom, cooling chassis both sides of operation inserts in the fixing seal liquid bath of both sides, bellows gas outlet; Sealing plate is made annular or rectilinear motion in company with chassis, thereby reaches the cooling chassis of motion and the fixing dynamic seal (packing) purpose between the bellows.The a small amount of granule bulk cargo 12 that from the pallet grate bar gap, spills simultaneously is by collecting with the bulk cargo catch tray of chassis consubstantiality, and moves to the emptying point and together be discharged in the hopper with sintering deposit.

Because of the utility model does not have specific (special) requirements to equipment and material, therefore no matter be to adopt circular cooler or straight line cooler, no matter be the construction of new factory or modernize and expand the existing factory, all can adopt the utility model technology.

More than; Be merely the preferred embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claim was defined.
