Description
Affiliated technical field
The utility model relates to a kind of novel concrete production line preheater inner barrel, is the substitute of preheater heat resisting steel inner core, and especially wear-resisting, high temperature resistant, decay resistance is far above traditional heat resisting steel inner core.
Background technology
Novel concrete industry fast development, yet the manufacturing of the preheater inner barrel of these production lines overwhelming majority employing so far heat resisting steel have been entered since 21 century.Heat resisting steel has mechanical performance preferably in temperature below 1000 ℃, but when temperature during greater than 1000 ℃, its mechanical performance then reduces greatly.As everyone knows; 3 grades, 4 grades, 5 grades inner cores of cement kiln preheaters; to stand washing away of 500-1200 ℃ of high temperature and high material concentration air-flow for a long time; harmful components such as simultaneously a large amount of potassium, sodium, chlorine, sulphur corrode the heat resisting steel inner core; make the preheater inner barrel lacing film usually can be, cause putty and be forced to stop the kiln repairing because of the not anti-high temperature of material deforms or breaking releasing.Usually the heat resisting steel inner core its make the life-span also only one year about, fee of material and maintenance cost height, burst accident direct losses and indirect loss are big.Though it is many that ceramic inner barrel of preheater in the market improves than heat resisting steel inner core at wear-resisting, high temperature resistant, decay resistance, the heat poor performance of shaking easily produces micro-crack, and the inner core lacing film is come off.
Summary of the invention
In order to overcome that existing heat resisting steel inner core life cycle is short, price is high and the defective of shaking property of the heat difference of ceramic inner barrel in the market, it is that primary raw material is produced the ceramic inner barrel lacing film that the utility model adopts aluminium oxide, the lacing film structure is taked the design of " inferior cucurbit " type, is the concave-convex clutch assembling mode between the lacing film.The utility model can substitute the shaking property of ceramic inner barrel heat of traditional heat resisting steel inner core and improvement, and its cost is reduced, and good stability and life cycle prolong.
The technical scheme that its technical problem that solves the utility model adopts:
1, contour structures design
The utility model is combined into the rounded cylindrical structure by ceramic lacing film, inner core is combined into the rounded cylindrical structure by 36 equal portions lacing films, the main body lacing film is shaped as " inferior cucurbit " type structure, the right and left is a tongue and groove, convex arc and concave arc tangent line intersect, cambered surface seamlessly transits, and ring lacing film of the end one is fixed by ceramic fixture.The lacing film profile adopts " inferior cucurbit " design principle to be: disperse ceramic lacing film to concentrate at the stress of environment for use, the heat of improving pottery itself performance of shaking prolongs service life of the present utility model and reduces the generation of burst accident; Is concave-convex type interlock design in conjunction with the limit, principle is to increase the utility model firm, stable in environment for use, reduces the vibrations injury that causes because of environmental factor; The base ring lacing film is fixed by ceramic connecting piece, and principle also is to increase the utility model firm, stable in environment for use, simultaneously the utility model ceramic inner barrel base ring lacing film is protected.
The utility model ceramic inner barrel barrel is thick to be 60mm, and internal diameter and height design according to customer requirements.
2, raw material selection
Ceramic members such as the utility model ceramic inner barrel lacing film are finalized the design by designing a model into mould with common 80-90 aluminium oxide ceramics raw material proportioning, and firing temperature 1800-1900 ℃, 1400-1600 ℃ of typing back refractory temperature, Morse hardness is greater than 8.According to pottery have high temperature resistant, anti-oxidant, wear-resistant, mechanical strength is high, hardness is high, the characteristics of a series of premium properties such as corrosion-resistant, performance indications such as the utility model (maximum temperature is less than 1200 ℃) performance variation in environment for use is little, wherein wear-resisting, high temperature resistant, anti-erosion are better than the heat resisting steel inner core; Cost, price are lower than the heat resisting steel inner core; In light weight, only be half of heat resisting steel.
The beneficial effects of the utility model are: main performance index surpasses the heat resisting steel inner core; Life cycle is long, and the user produces, maintenance cost reduces; For country saves rare metal resources.
