Description
Technical field
The utility model relates to a kind of internal barrel of ceramic pre-heater of chain structure, in preheater of rotary cement kiln.
Background technique
Preheater of rotary cement kiln inner cylinder early stage mostly uses heat-resisting alloy steel lacing film to constitute, and in practical high temperature and corrosivity
Under operating condition, steel part is easily oxidized, corrodes, and leads to its deformation, peels off, even falls off, and it is short, at high cost simultaneously etc. that there are service lifes
Problem cannot function as a kind of ideal preheater inner barrel material.
To solve the problems, such as that inner cylinder lacing film service life is short, at high cost, the preheater inner barrel of some producers production is using pottery
Porcelain lacing film, is improved in terms of material property than heat resisting steel, due to material composition, the existing defects such as design structure, such as spiral shell
Bolt junction is also easy to produce stress concentration, and thermal shock resistance is poor, is easy to produce crackle or even ablation fracture in use, delays life
It produces, while structure is complicated, installation is inconvenient, seriously affects the stability and continuity of manufacture of cement.
Summary of the invention
The purpose of the present invention is to provide a kind of high temperature resistants, corrosion-resistant, not easy to break, the preheater ceramics for using the time to grow
Inner tube structure.
To achieve the above object, the technical solution adopted in the utility model are as follows: in a kind of ceramic pre-heater of chain structure
Cylinder, including cylinder, the cylinder are formed by connecting by the identical ceramic wafer hinge of several groups, are led between the ceramic wafer and ceramic wafer
Crossing ceramic wafer connector, successively hinge connects to form cylinder, and ceramic wafer connector one end is fixed on steel alloy hanging seat, institute
Steel alloy hanging seat is stated to hang on the inner wall of preheater.
Wherein, ceramic wafer and ceramic wafer hinge engaging structure are by ceramic wafer, ceramic wafer connector, steel alloy pin shaft and alloy
Steel hanging seat composition, the steel alloy pin shaft sequentially passes through ceramic wafer connector and ceramic wafer from ceramic wafer connector one end, described
Ceramic wafer is connect with ceramic wafer by ceramic wafer connector, and hinge arrangement is formed, and the ceramic wafer connector other end is fixed on
On steel alloy hanging seat, the steel alloy hanging seat is hung on the inner wall of preheater.
It is provided with connecting hole on the steel alloy hanging seat, is used for fixed ceramic plate connector.
The ceramic wafer and ceramic wafer connector is corundum ceramics or silicon carbide reaction-sintered matter ceramics or recrystallization
Silicon carbide ceramics.
The ceramic wafer section is parallelogram.
The steel alloy pin shaft and steel alloy hanging seat are heat-resisting alloy steel.
The present utility model compared with the existing technology, has the following advantages that and effect:
1, ceramic wafer and ceramic wafer are connected by ceramic wafer connector, using single piece type overall structure, are avoided using bolt
The mode of connection can be effectively improved the thermal shock performance of ceramics, Crack prevention and ablation breakage problem.
2, ceramic wafer connector one end is fixed on steel alloy hanging seat by steel alloy pin shaft and (is provided on steel alloy hanging seat
Connecting hole), steel alloy hanging seat is hung on the inner wall of preheater, not the use of bolt, effectively save cost.
3, ceramic wafer section is that parallelogram is conducive to combining closely between two ceramic wafers, prevents from leaking out, increases pottery
Stability of the porcelain plate in use environment.
4, the ceramic wafer and ceramic wafer connector are corundum ceramics or silicon carbide reaction-sintered matter ceramics or tie again
Brilliant silicon carbide ceramics, so that inner tube structure part high temperature resistant, corrosion-resistant, long service life.
