Description

Sintering machine wind box head, tail sealing device
Technical field
The utility model relates to the sintering machine apparatus field, relates in particular to sintering machine wind box head, tail sealing device.
Background technology
Existing sintering machine wind box is installed in the sintering pallet below, on trolley track, move after filling compound on the sintering pallet, light a fire at the compound top through ignition furnace, bellows are from the chassis downdraft, make compound by the downward sintering in the top of sintering pallet, in order to make bellows reach good exhausting effect, just must guarantee between sintering machine wind box and the sintering pallet reliable sealing is arranged, do not produce and leak out.The bellows both sides are by bellows slideway and sintering pallet sealing, and the head of bellows and afterbody are by sintering machine wind box head, tail sealing device sealing.The existing sintering machine wind box head that uses, tail sealing device adopt the patented technology of applicant " ZL200520051354.5 sintering machine head end, tail sealing device ", its structure is being lifted individual layer sealing plate 6 by two leverage 1 and screw rod adjusting device 4 tops of being located at individual layer sealing plate 6 both ends respectively as shown in Figure 1; Leverage 1 is made of weight 11, lever 12, top board 13 and gripper shoe 14.Along with the sintering pallet also and then motion of sintering pallet bottom girder 5 of travelling in orbit, when sintering pallet moves to sintering machine wind box head, tail sealing device present position, chassis bottom girder 5 is close to individual layer sealing plate 6 and is moved, thereby reaches the purpose to sintering machine wind box head, tail sealing.Because sintering pallet 5 moves, certainly lead to friction and make the wearing and tearing of individual layer sealing plate 6 end faces, make individual layer sealing plate 6 not reach requirement of strength after wearing up to a certain degree, must change individual layer sealing plate 6, accidents caused otherwise individual layer sealing plate 6 can rupture, warp.And when changing individual layer sealing plate 6, must carry out contraposition and adjustment to leverage 1 and screw rod adjusting device 4, its replacing time generally needs 2~3 days at least than long.Therefore, the sintering plant that has is taked the method for integral replacing sealing device, but its recondition expense is very high, causes the cost waste.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of long service life is provided, and is convenient to dismounting and replacing, the sintering machine wind box head of saving maintenance cost, tail sealing device.
Sintering machine wind box head of the present utility model, tail sealing device, comprise screw rod adjusting device and leverage, the screw rod adjusting device is between two groups of leverages, described screw rod adjusting device and leverage top are equiped with the bottom sealing plate, bottom sealing plate middle part is hinged with the screw rod adjusting device, bottom sealing plate two ends link to each other with the leverage that is positioned at screw rod adjusting device both sides respectively, and bottom sealing plate top is equiped with the upper strata sealing plate.
Described bottom sealing plate is provided with stopper slot, and the upper strata sealing plate is provided with limited block, and limited block places in the stopper slot.
Described bottom sealing plate is provided with brace rod.
Sealing plate both sides, described upper strata are provided with hole for hoist.
Compared with prior art, advantage of the present utility model just is: existing individual layer sealing plate is changed into the double-layer seal plate of being made up of bottom sealing plate and upper strata sealing plate, after the wearing and tearing of upper strata sealing plate, only need to change the upper strata sealing plate, the bottom sealing plate that needn't dismounting links to each other with the screw rod adjusting device with leverage, avoid loaded down with trivial details contraposition work and adjustment work, thereby saved a large amount of maintenance time; Simultaneously do not need sealing device is taked the mode of integral replacing yet, save maintenance cost; After sealing plate part, upper strata is worn, can utilize the screw rod adjusting device that the bottom sealing plate is adjusted, make the sintering pallet bottom girder be close to sealing plate, continue to play the effect of sealing; After the fracture of upper strata sealing plate, supported by the brace rod of bottom sealing plate, the accident that can not warp, the upper strata sealing plate can grind fully or change near after having ground fully again; The both sides of upper strata sealing plate are provided with hole for hoist, can make things convenient for the dismounting and the replacing of upper strata sealing plate.

The specific embodiment
As Fig. 2, shown in Figure 3, sintering machine wind box head of the present utility model, tail sealing device, comprise screw rod adjusting device 4 and leverage 1, screw rod adjusting device 4 is between two groups of leverages 1, screw rod adjusting device 4 and leverage 1 top are equiped with bottom sealing plate 3, bottom sealing plate 3 middle parts and screw rod adjusting device 4 are hinged, and bottom sealing plate 3 two ends link to each other with the leverage 1 that is positioned at screw rod adjusting device 4 both sides respectively, and bottom sealing plate 3 tops are equiped with upper strata sealing plate 2.Leverage 1 comprises weight 11, lever 12, top board 13 and gripper shoe 14, and lever 12 1 ends link to each other with weight 11, and the other end links to each other with top board 13, and lever 12 middle parts are supported on the gripper shoe 14.Existing individual layer sealing plate 6 is changed into the double-layer seal plate of forming by bottom sealing plate 3 and upper strata sealing plate 2, after 2 wearing and tearing of upper strata sealing plate, only need to change upper strata sealing plate 2, the bottom sealing plate 3 that needn't dismounting links to each other with screw rod adjusting device 4 with leverage 1, avoid loaded down with trivial details contraposition work and adjustment work, thereby saved a large amount of maintenance time; Simultaneously do not need sealing device is taked the mode of integral replacing yet, save maintenance cost; Bottom sealing plate 3 is provided with stopper slot 31, upper strata sealing plate 2 is provided with limited block 21, limited block 21 places in the stopper slot 31, after sealing plate 2 parts in upper strata are worn, can utilize 4 pairs of bottom sealing plates 3 of screw rod adjusting device to adjust, make bottom sealing plate 3 ask upper strata sealing plate 2 to be close to sintering pallet bottom girder 5, continue to play the effect of sealing.Bottom sealing plate 3 is provided with brace rod 32, after 2 fractures of upper strata sealing plate, supported by the brace rod 32 of bottom sealing plate 3, and the accident that can not warp, upper strata sealing plate 2 can grind fully or change near after having ground fully again.Sealing plate 2 both sides in upper strata are provided with hole for hoist 22, can make things convenient for the dismounting and the replacing of upper strata sealing plate 2.
