The high-temperature layer of the straight barrel part is formed by building high-alumina bricks in a surrounding mode. The high-temperature layer of the horn mouth part is formed by building silicon mullite bricks in a surrounding mode. By means of the technical scheme, the horn mouth part adopts composite lining structures of the silicon mullite bricks and clay bricks, the silicon mullite bricks have functions of corrosion resistance and abrasion resistance, the manufacture cost of the lining is reduced due to the clay bricks, and calcium silicate boards and heat insulation bricks of the heat insulation layer have functions of good heat preservation and energy saving.
Description
Technical field
The utility model relates to a kind of cement in vertical kiln kiln body.
Background technology
The kiln body of cement in vertical kiln is made up of the straight drum part of bottom and the horn mouth on top.Wherein, horn mouth is the main position that the cement kiln material burns till reaction.Under the firing temperature, the refractory material kickback at cement kiln material and horn mouth place corrodes refractory material, shortens the service life of refractory material.On the other hand, part kiln material is bonded in the horn mouth surface, forms sticking limit, and overslaugh kiln material is descending smoothly, becomes the obstacle that disturbs shaft kiln to produce.
The utility model content
The utility model technical problem to be solved provides a kind of cement in vertical kiln kiln body, has premium properties such as anti-erosion, wear-resistant, not sticking limit, low heat conduction, low cost.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: cement in vertical kiln kiln body; Comprise straight drum part and horn section; Said kiln body comprises heat zone, the cast bed of material and thermal insulation layer from inside to outside successively, and the heat zone of said straight drum part is formed by the high-alumina brick brick work, and the heat zone of said horn section is formed by the siliceous mullite brick brick work.
As preferably; Be provided with the undercloak that forms by the clay brick brick work between said heat zone, the cast bed of material; Said siliceous mullite brick is provided with projection, and corresponding said projection is provided with groove on the said clay brick, and said siliceous mullite brick is connected with groove through said projection with said clay brick.
As preferably, the thickness of said siliceous mullite brick is 60-100mm, and the thickness of said clay brick is 150-250mm.
As preferably, the inside upper part of said high-alumina brick is provided with chamfering.
As preferably, said thermal insulation layer comprises ceramic warming plate and porous heat-insulating brick from inside to outside successively, and the thickness of said porous heat-insulating brick is 300 ± 100mm.
The utility model is owing to adopted technique scheme; Horn section adopts the compound lining structure of siliceous mullite brick and clay brick; Siliceous mullite brick performance anti-erosion, anti abrasive effect, clay brick reduces the lining cost, and the calcium silicate board of thermal insulation layer and insulating brick produce good insulation, energy-conserving action.

The specific embodiment
Further describe below in conjunction with the specific embodiment of accompanying drawing the utility model.
Illustrated in figures 1 and 2 is the utility model cement in vertical kiln kiln body; Comprise straight drum part and horn section; Said kiln body comprises heat zone 1, the cast bed of material 2 and thermal insulation layer 3 from inside to outside successively; The heat zone of said straight drum part is formed by high-alumina brick 11 brick works, and the heat zone of said horn section is formed by siliceous mullite brick 12 brick works.Be provided with the undercloak that forms by clay brick 13 brick works between said heat zone 1, the cast bed of material 2; Said siliceous mullite brick 12 is provided with projection 121; Corresponding said projection is provided with groove on the said clay brick 13, and said siliceous mullite brick 12 is connected with groove through said projection 121 with said clay brick 13 and is bonding with high-strength phosphate chamotte.The thickness of said siliceous mullite brick 12 is 60-100mm, and the thickness of said clay brick 13 is 200mm.
The inside upper part of said high-alumina brick 11 is provided with chamfering 111.This high-alumina brick 11 is built the formation air guide structure by laying bricks or stones, after the normal operation of igniting, can progressively enlarge the voidage between the material, reduces flowing resistance, improves unit production capacity and grog unit-hour output.
Said thermal insulation layer 3 comprises ceramic warming plate 31 and porous heat-insulating brick 32 from inside to outside successively, and the thickness of said porous heat-insulating brick 32 is 300mm.Pottery warming plate 31 is made up of materials such as ceramic fibre, aluminosilicate refractory fibers respectively with porous heat-insulating brick 32; For surface temperature and the unlikely raising of radiation loss that guarantees cement in vertical kiln kiln body; Adopt this energy-saving supporting insulation material that kiln surface temperature and radiation loss are reduced greatly; Kiln inner edge wall temperature improves, and the section temperature field gradient tends to balance, and then improves the calcining situation.
The reason on generation erosion of horn mouth place and sticking limit is the reaction of clinker and high alumina refractories.Siliceous mullite brick system is the commercially available silicon fire resistant materials not of principal component with alumine, carborundum, and the reason that siliceous mullite brick has better anti-erosion, abrasion resistance properties is that the SiC in the siliceous mullite brick at first is oxidized to SiO gas; SiO gas diffuses to the brick surface, and becomes SiO at surface oxidation
2Subsequently, SiO
2Form enamel on the brick surface, the shutoff pore slows down the service life of corroding and improving material.
The cast bed of material is aggregate (graininess) by light ceramic and grog, makes bond with aluminate cement, suitably add the lightweight coal ash powder and float other insulation material such as pearl, additive is formulated in right amount, has characteristics such as intensity is moderate, heat insulation effect is good.
