Abstract
The utility model discloses a kiln was used in black talc production sandwich silicon is refractory brick not has the brick body, have on the brick body and pierce through its hollow part on surface from top to bottom, hollow some intussuseption is filled with aluminium silicate fiber bock, the area that hollow partial volume accounted for 14-12, aluminium silicate fiber bock of brick body bulk volume is greater than hollow partial area. The utility model discloses an advantage: the main part adopts the not high -pressure shaping of brick batching of ordinary silicon, and high temperature burn's hollow silicon is the brick not, the aluminium silicate fiber bock that the size is corresponding is packed to hollow part, and the aluminium silicate fiber bock coefficient of heat conductivity of packing is very low, thus it not only have silicon not the brick high temperature resistant, the high temperature strength good, the heat resistanceheat resistant shake stability good, anticorrosive, do not peel off, do not split, loading softening temperature 1500 DEG C with first -class advantage, still have that the quality is light, coefficient of heat conductivity low and keep warm effectual advantage simultaneously to greatly reduced the exterior temperature of kiln, reduced the heat loss, reduced the kiln heat rate.
Description
Technical field
The utility model relates to black talc and produces correlative technology field, is specifically related to the sandwich silicon not refractory brick of kiln in the production of a kind of black talc.
Background technology
China's black talc mineral resources are quite abundant, and the Room, territory, Jiangxi Province up-to-date exploration result in 2009 shows, Shangrao City Guangfeng County, Jiangxi is domestic, black talc ore body intermittently extends 20 kilometers, reserves reach more than 1,000,000,000 tons, and reserves are big to be occupied first of the world, and yield is still less than 1,000 ten thousand tons.Black talc industrial base, Guangfeng County, Jiangxi Province is approved for provincial industrial base, Jiangxi Province a few days ago, and black talc, New Energy Industry are put into Jiangxi Province " 12 " development plan simultaneously.Black talc is rare quality raw materials after brightening, and economic worth is huge, greatly can alleviate China's high-grade talcum market situation that supply falls short of demand.
Black talc from exploitation out, needs, through steps such as ore dressing, fragmentation, calcinings, to re-use after making whiten stone.In calcination process, use the relevant device such as rotary kiln, tunnel cave, because the temperature of calcining is very high, more than 1000 DEG C can be reached, therefore very high requirement is had to the high temperature resistant and heat-insulating property of kiln various in calcination process, this is not only to reduce energy consumption, is also to ensure burning quality, improves black talc calcining whitening effect.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provides the sandwich silicon not refractory brick of kiln in the production of a kind of black talc, significantly can improve the heat insulation effect of kiln, energy-saving and cost-reducing.
In order to reach the purpose of this utility model, technical scheme is as follows:
The sandwich silicon not refractory brick of kiln in a kind of black talc production, there is brick body, it is characterized in that, described brick body has the hollow parts penetrating its upper and lower surface, alumina silicate fibre block is filled with in described hollow parts, the volume of described hollow parts accounts for 1/4 ~ 1/2 of brick body cumulative volume, and the area of alumina silicate fibre block is greater than the area of hollow parts.
Preferably, the sidewall of described hollow parts is provided with outwardly fin, and the side of alumina silicate fibre block is provided with the groove be inwardly recessed, described fin and described groove match.
Preferably, on four angles of alumina silicate fibre block, be provided with outwardly projection, the position that hollow parts is corresponding has the depression be inwardly recessed, and described projection is inserted in described depression.
The beneficial effect that the utility model has:
Main body adopts common siliceous mullite brick batching high-pressure molding, the hollow siliceous mullite brick of high-temperature firing; Hollow parts fills the corresponding alumina silicate fibre block of size, the advantage of the sandwich silicon of this kind of structure not refractory brick is: the alumina silicate fibre block thermal conductivity factor of filling because main body is siliceous mullite brick is very low, so it not only have siliceous mullite brick high temperature resistant, elevated temperature strength good, heat-resistant knocking stability good, anticorrosive, do not peel off, do not rupture, refractoriness under load at 1500 DEG C with first-class advantage, also have that quality is light, thermal conductivity factor is low and the advantage of high insulating effect simultaneously, thus greatly reduce the external skin temperatures of kiln, decrease heat loss, reduce kiln hear rate.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is further described, but protection domain of the present utility model is not only confined to embodiment.
Shown in composition graphs 1 and Fig. 2, in a kind of black talc production, the sandwich silicon not refractory brick of kiln, has brick body 1, described brick body 1 has the hollow parts 3 penetrating its upper and lower surface, be filled with alumina silicate fibre block 2 in hollow parts 3.The volume of described hollow parts 3 accounts for 1/4 ~ 1/2 of brick body 1 cumulative volume, can improve heat-insulating property like this, can not reduce again the structural strength of of whole refractory brick itself.The area of alumina silicate fibre block 2 is greater than the area of hollow parts 3.Brick body 1 is the same with the thickness of alumina silicate fibre block 2, and in the present embodiment, the size of brick body 1 is 200mm*270mm, and the size of hollow parts 3 is 100mm*160mm, and the volume of hollow parts 3 accounts for 1/3 of brick body 1 cumulative volume.And the size of alumina silicate fibre block 2 is slightly larger than hollow parts 3, filled by alumina silicate fibre block 2 like this after entering, it is inner that alumina silicate fibre block 2 well can be fixed on hollow parts 3, can not come off.
Shown in composition graphs 3, for embodiment 2 of the present utility model, in order to improve the steadiness of alumina silicate fibre block 2 at hollow parts 3 further, the sidewall of hollow parts 3 is provided with outwardly fin, the side of alumina silicate fibre block 2 is provided with the groove be inwardly recessed, during assembling, and described fin and described groove match, make alumina silicate fibre block 2 can better be fixed on hollow parts 3 inner, can not come off.Certainly, also can be that the side of alumina silicate fibre block 2 arranges fin, and hollow parts 3 inwall arranges the groove matched.
Shown in composition graphs 4, on four angles of alumina silicate fibre block 2, be provided with outwardly projection 4, corresponding, hollow parts 3 has the depression be inwardly recessed, and described protruding 4 are inserted in described depression, alumina silicate fibre block 2 and brick body 1 are snapped together, be convenient to install and take off, simultaneously in use also difficult drop-off.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this description has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
