Description
Technical field:
The utility model relates to rotary kiln manufacturing technology field, in particular to a kind of high temperature resistant rotary kiln kiln body.
Background technique:
In existing rotary kiln device, rotary kiln kiln body is that steel plate is welded simplified, inner lining refractory.Fire resisting
Material work bad environments, condition are harsh.It should have the following characteristic: alkali resistant erosiveness is strong, can be chronically at
It works under 1200-1300 DEG C of high temperature, without damaging, the impact of dynamic loading can be born, the erosion of furnace charge can be resisted, be resistant to High Temperature Gas
The erosion of stream.Refractory material used in rotary kiln based on high-alumina brick and magnesite-chrome brick, then made using clay brick by low temperature drying kiln
Liner.Existing rotary kiln kiln body refractory material insulation effect is poor, and heat insulation layer thickness is thick, weight weight, and service life is short.
Utility model content:
The technical problem to be solved by the present invention is to provide a kind of high temperature resistant rotary kiln kiln bodies, and the arrangement achieves reductions
Refractory thickness, it is light-weight, increase refractory material service life, insulation effect is good, reduces temperature diffusion, high temperature resistant, structure
Simply, safety and environmental protection, sufficiently, burning effect is good for burning.It is poor to overcome existing rotary kiln kiln body refractory material insulation effect, is insulated
Thickness degree is thick, weight weight, the short deficiency of service life.
Technical solution adopted in the utility model is: a kind of high temperature resistant rotary kiln kiln body, including kiln body outer cylinder；Outside kiln body
Cylinder laid inside aeroge ceramic fibre composite plate, aeroge ceramic fibre composite board internal are laid with mullite tile；Aeroge
Ceramic fibre composite plate includes aerogel layer and ceramic beaverboard, and aerogel layer is laid on kiln body outer tube inner wall, aerogel layer
Ceramic beaverboard is arranged in inside.
Aeroge ceramic fibre composite plate with a thickness of 20~200mm.
Mullite tile inner wall is equipped with pusher item in spiral distribution, and kiln body one end kiln hood is equipped with feed inlet, and kiln body is another
One end kiln tail is equipped with fuel gas inlet and discharge port.
The beneficial effects of the utility model are: the utility model realizes reduction refractory thickness, and it is light-weight, increase resistance to
In the fiery materials'use service life, insulation effect is good, reduces temperature diffusion, and high temperature resistant, structure is simple, safety and environmental protection, and burning sufficiently, is burned
Effect is good.
Detailed description of the invention:
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the schematic cross-section of the utility model.
Specific embodiment:
As shown in Figure 1 and Figure 2, a kind of high temperature resistant rotary kiln kiln body, including kiln body outer cylinder 1；1 laid inside gas of kiln body outer cylinder
Gel ceramic fiber composite plate 2,2 laid inside mullite tile 3 of aeroge ceramic fibre composite plate；Aeroge ceramic fibre is multiple
Plywood 2 includes aerogel layer and ceramic beaverboard, and aerogel layer is laid on 1 inner wall of kiln body outer cylinder, setting on the inside of aerogel layer
Ceramic beaverboard.
Aeroge ceramic fibre composite plate with a thickness of 20~200mm.
3 inner wall of mullite tile is equipped with pusher item in spiral distribution, and kiln body one end kiln hood is equipped with feed inlet, and kiln body is another
One end kiln tail is equipped with fuel gas inlet and discharge port.
In use, material is arranged in spiral distribution by kiln cylinder inner wall by the kiln hood enterprising material mouth feed of kiln body
Kiln tail discharge outlet of the pusher item from entrance to kiln body slowly flows, and fuel gas inlet is burnt to material flame at the kiln tail of kiln body
Heating, to reach drying materials effect.
Aeroge ceramic fibre composite plate 2 has superior heat-proof quality, can reduce heat insulation layer thickness, high temperature resistant；In fire
Field, which neutralizes, does not discharge any noxious material under high temperature, is free of asbestos, polybrominated biphenyls；It can be resistant to for a long time in addition to hydrofluoric acid, highly basic
Most of acid or alkali environment has the characteristics that not decompose and never degenerate.
Mullite tile 3 is a kind of good refractory material, and refractory temperature can reach 1790 DEG C or more.Loading softening starts
1600-1700 DEG C of temperature.The slight 70-260MPa of room temperature pressure resistance.Thermal shock resistance is good.It, which has, expands uniform, thermal shock resistance
Feature fabulous, load softening point is high, high-temerature creep value is small, hardness is big, resistance to chemical corrosion is good；Compared with refractory brick, it can increase
Add service life.
It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being
It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technical effect；Needs are used as long as meeting, all in this reality
Within novel protection scope.
