Description
Technical field
The utility model belongs to heat sealing technical field, particularly relates to a kind of sealed adapter sleeve as connected bellows and airduct in the equipment such as sintering machine, central cooler.
Background technique
In iron and steel is produced, SINTERING PRODUCTION is one of important operation, and it provides the raw material of high-quality for blast furnace ironmaking.Iron-bearing material, fuel, solvent etc. fit over together by sintering exactly in proportion, through being mixed, granulate after adding water-wet, be layered on agglomerating plant, carry out igniting sintering from the top down, bellows while igniting below sintering machine start exhausting, while fuel in composite ore carrying out from top to bottom is burnt, soak difficulty melt material by easily melting matter melts, liquid phase cools gradually melts material by difficulty and sticks together, this process is until sintering machine grate ends, and the block object obtained is sintering deposit.When sintering machine is produced, induced draft fan is exhausting ceaselessly, make to form negative pressure state in the bellows below chassis, be beneficial to mineral aggregate burn from top to bottom, in order to the exhausting effect making bellows reach good, must ensure that sintering system has reliable sealing, usually be connected by a stiffness bellows between sintering machine wind box with (always) airduct, because the gas in bellows is generally high temperature and high pressure gas, long use, when high temperature and high pressure gas enters airduct by stiffness bellows from bellows, easily cause stiffness bellows broken by vibration, lose seal action, not only increase repair and maintenance cost, also be unfavorable for reducing system energy consumption.
Summary of the invention
The purpose of this utility model is to provide the flexible flexible link of heat sealing of a kind of good sealing effect, long service life.
To achieve these goals, the utility model takes following technical solution:
The flexible flexible link of heat sealing, comprising: upper adpting flange, described upper adpting flange is provided with the through hole be uniformly distributed along the circumference; The rubber sleeve of hollow, is provided with the spring steel of coiled coil in described rubber sleeve; Stainless steel inner lining cover, described stainless steel inner lining cover is arranged in described rubber sleeve; Lower adpting flange, described lower adpting flange is provided with the through hole be uniformly distributed along the circumference; The top of described rubber sleeve is connected with lower adpting flange with described upper adpting flange respectively with bottom.
The utility model is further improved to, and described upper adpting flange and lower adpting flange is provided with the lower deep gouge of concentric ring, and it is peripheral that described through hole is arranged at described lower deep gouge; The top of described rubber sleeve and bottom have the flange horizontally outward extended, and the flange at described rubber sleeve top is arranged in the lower deep gouge of described upper adpting flange, and the flange bottom described rubber sleeve is arranged in the lower deep gouge of described lower adpting flange.
The utility model is further improved to, and the top of described stainless steel inner lining cover has the upper flange horizontally outward extended, and the upper flange of stainless steel inner lining cover is set up in the lug upper surface at rubber sleeve top.
The utility model is further improved to, and the external diameter of described stainless steel inner lining cover is less than the internal diameter of rubber sleeve, is Spielpassung between stainless steel inner lining cover and rubber sleeve.
As shown from the above technical solution, the utility model arranges a stainless steel inner lining cover in rubber sleeve.Stainless steel inner lining cover is utilized to be kept apart by high temperature and high pressure gas, high temperature and high pressure gas can not directly contact with rubber sleeve, gas is avoided to cause damage to rubber sleeve, the spring steel of coiled coil is set simultaneously in rubber sleeve, increase its intensity, extend the working life of rubber sleeve, thus ensure sealing effect.And adopting upper and lower adpting flange to be fixed rubber sleeve, linkage structure is simple and firm, ensures in thermal distortion situation simultaneously, and heat sealing flexibility is flexible coupling can axial and radial distortion and not impaired.
