Abstract

The utility model relates to a sealing device for the two end bodies of improved trolley of sintering machine for preventing the air leakage of the side part. The utility model is characterized in that a banding seal gasket is fixed on the upper surface of a shifting board which is a sealed board. The cross-section of the banding seal gasket is bowl shaped. The two side edges of the banding seal gasket are V-shaped awl edges. When installing, the banding seal gasket is embedded in the shifting board groove accompanied with the shifting board. The V-shaped awl edges of the two sides are compressed and sealed with the inner side edge of the shifting board groove. The mounting gap between the shifting board and the shifting board groove is eliminated and is effectively sealed. In addition, an upper limiting ring is welded on the bottom surface of the shifting board groove and is positioned on the periphery of each axis pin. A lower limiting ring is welded on the upper surface of the shifting board. The periphery of each set of the upper limiting ring and the lower limiting ring is sheathed with compressed spiral springs. Under the action of the spring force, the squeezing between the bottom plane of the shifting board and a fixing slideway on a sintering air box is ensured. The normal wear between the bottom plane of the shifting board and the fixing slide on the sintering air box is compensated in time. The good sealing state is maintained all the time. The air leakage phenomenon of the two end bodies of the trolley of the sintering device is effectively solved.

Description

Seal device of sintering machine pallet

Technical field

The utility model belongs to the air feeder of sintering machine, the sealing device that especially a kind of air of improved sintering pallet is supplied with.

Background technology

Domestic existing sintering machine, when the high negative pressure down draft sintering, system's air leakage phenomena that ubiquity is more serious, and in total air leak rate of air curtain, the inleakage of sintering pallet two ends side portion accounts for more than 30%, for preventing that sidepiece from leaking out, existing sintering pallet two ends body adopts the leaf spring type sealing device, but this device can't solve because of caused the leaking out of assemblage gap between sealing cell body and the sealing plate, simultaneously, under the environment of many dust, the dust of high concentration easily makes leaf spring lose efficacy, and causes sealing plate to move, cause the sealing device of sintering pallet two ends body to lose efficacy at last, and the sidepiece of sintering pallet leaks out still seriously, and it is very harmful to SINTERING PRODUCTION to leak out, and has both increased energy consumption, reduced negative pressure again, reduce the sintering air quantity, reduced the output and the quality of sintering deposit, and brought a large amount of noises to form noise pollution.

Summary of the invention

The purpose of this utility model is the sealing device of a kind of improved sintering pallet of design two ends body, can solve the sidepiece air leakage phenomena of sintering pallet two ends body effectively, improves the output and the quality of sintering deposit, further cuts down the consumption of energy, and improves noise pollution.

The purpose of this utility model is achieved like this: a kind of by be packed in trip board slot in the long recess of sintering pallet two ends bodies bottom with bolt be seal groove and be the seal device of sintering machine pallet that sealing plate is formed with the trip plate that bearing pin is suspended on trip board slot bottom, it is characterized in that bonding installs banded sealing gasket on plane on the trip plate, this banded sealing gasket is with high temperature resistant, the high resiliency material is made, its cross section is that bowl-type and dual-side are V-arrangement awl limit, during installation, the V-arrangement awl limit, both sides of this banded sealing gasket embeds in the trip board slot, inner side edge extruding driving fit with the trip board slot, eliminate the assemblage gap between trip plate and the trip board slot, make between trip plate and the trip board slot and obtain effective seal, in addition, be positioned at the periphery of each bearing pin, the upper limit ring is welded on the groove bottom of trip board slot, the lower limit ring is welded on plane on the trip plate, on every group, the concentricity line of lower limit ring and etc. cylindrical, between trip board slot and trip plate, on each group, the equal suit compression helical spring of the periphery of lower limit ring, under the effect of elastic force, make the upper and lower displacement of trip plate energy elasticity, when the chassis wheel rolls the drive trolley movement, can guarantee to swim and produce extruding between the ground way on the bellows of the baseplane of plate and sintering machine bottom and form good sealing effectiveness, and when normal wear occurring between trip plate and the ground way, in time be compensated, still make trip plate and ground way keep squeezed state, thereby remain good sealing effectiveness, so, just realized solving effectively the sidepiece air leakage phenomena of sintering pallet two ends body, improved sintering deposit output and quality and improve the purpose of production environment.

The seal device of sintering machine pallet that the utility model is carried is rational in infrastructure, and is safe and reliable, solved the sidepiece air leakage phenomena of sintering pallet two ends bodies effectively, saved the energy, improved the output and the quality of sintering deposit, improved environment.

Now the seal device of sintering machine pallet of in conjunction with the accompanying drawings and embodiments the utility model being carried is further described.

The specific embodiment

Because of a sintering pallet left side, the sealing device of right two ends body is identical, this specific implementation method is that example is described with the left end body only, from Fig. 1, Fig. 2, Fig. 3, among Fig. 4 as can be seen: the trip board slot in a kind of left end body bottom long recess 3 by the chassis 2 that is packed in sintering machine with bolt 13 is a seal groove 4 and to be suspended on the trip plate of swimming board slot 4 belows with bearing pin 5 be the seal device of sintering machine pallet that sealing plate 10 is formed, it is characterized in that bonding installs banded sealing gasket 8 on plane on the trip plate 10, these banded sealing gasket 8 usefulness are high temperature resistant, highly elastic material is made, the cross section of this banded sealing gasket 8 is a bowl-type, its left side, the top of right two ends section has the rectangle plug, dual-side is V-arrangement awl limit, during installation, banded sealing gasket 8 with trip plate 10 together setting-in go into to swim in the board slot 4, but the V-arrangement of both sides awl limit is pushed on driving fit and the elasticity with the inner side edge of swimming board slot 4, bottom offset, eliminated the assemblage gap between trip plate 10 and the trip board slot 4, made between trip plate 10 and the trip board slot 4 to be sealed effectively; In addition, be positioned at the periphery of each bearing pin 5, upper limit ring 6 is welded on the groove bottom of trip board slot 4, lower limit ring 9 is welded on plane on the trip plate 10, on every group, lower limit ring 6,9 concentricity lines and etc. cylindrical, between trip board slot 4 and trip plate 10, on each group, lower limit ring 6, the equal suit compression helical spring 7 of 9 periphery, under the effect of elastic force, make on the trip plate 10 energy elasticity, bottom offset, when chassis wheel 1 rolls 2 motions of drive chassis, can guarantee to swim and produce extruding between the ground way 11 on the wind box 12 of the baseplane of plate 10 and sintering machine bottom and form good sealing effectiveness, and when normal wear occurring between trip plate 10 and the ground way 11, in time be compensated, still make and keep good squeezed state between trip plate 10 and the ground way 11, thereby remain good sealing effectiveness, so, just solved a sintering pallet left side effectively, the sidepiece air leakage phenomena of right two ends body, further energy efficient has improved the output and the quality of sintering deposit and has improved working environment.
