Technical field
The utility model relates to a kind of kiln, is specially a kind of superhigh temperature roller kilns that are used to fire raw material for refractory.
Background technology
At present, the processing method of aluminium base raw material for refractory mainly takes the raw ore behind the pick is directly carried out the method for sintering, is about to raw material and directly puts into kilns such as down-draft kiln, tunnel cave, square kiln and carry out sintering; Also have raw ore is crushed to certain particle through behind the pick, in rotary kiln, carry out sintering, according to requirement of client finished product is passed through screening more then.Said method belongs to traditional direct sintering, though the pick (mainly being to pick out material piece and the problematic material piece of order appearance quality index that does not bake) of grog behind the pick of process raw material and the sintering, but because the content inconsistent (ore bed difference or mining area difference) of alundum (Al in the raw material piece, clinker quality is still inhomogeneous after causing sintering, when being used for the production of articles of refractory material, can directly influence the qualification rate of fire resistive material product, and influence its serviceability; And direct sintering, can not normalized production, granule size is inhomogeneous, need reprocess, and producing, easily producing dust in the transportation, has polluted environment.
Along with the continuous development of art technology, people begin to produce the homogenization material of refractory material, and the main technique flow process is earlier with raw material crushing, abrasive dust, add the water moulding then, drying, sintering, the goods product that obtains, the specification unanimity, the content's index unanimity after burning till, does not need to sieve specification, can directly be used as abrasive brick, this product market and international market at home has the advantage of tangible quality, price competition.In above-mentioned technical process, sintering circuit is an important step that influences product quality, great majority adopt kilns such as rotary kiln, down-draft kiln, tunnel cave to burn till at present, though firing temperature can satisfy the technological requirement of raw material for refractory, but because raw material adopts accumulation mode in the kiln body, not only can't realize continuous production, it is inhomogeneous to the more important thing is that raw material is heated, and can't satisfy the quality index of homogenization material.With above-mentioned rotary kiln, tunnel caves etc. are compared, roller kilns have light-duty, energy-conservation, efficiently, easily realize advantages such as automation, belong to the continuity kiln, the kiln body comprises the preheating zone, high temperate zone and salband, usually be mainly used in magnetic material, catalyst, burning till and the glassware hot bending of pottery and powder body material, owing to require lower to firing temperature, generally be no more than 1400 ℃, correspondingly its insulation layer thickness is mostly below 460mm, the refractoriness of used refractory material is lower, so the thermal insulation fire-resistant layer structure in its high temperate zone can't satisfy the technological requirement of raw material for refractory.
Summary of the invention
The utility model for solve existing adopt when producing the refractory material homogenization material kilns such as rotary kiln, tunnel cave exist raw material be heated inhomogeneous, can't realize producing continuously and the high problem of energy consumption, and adopt roller kilns to have the thermal insulation fire-resistant layer unreasonable structure in high temperate zone, the problem that firing temperature is low provides a kind of superhigh temperature roller kilns that are used to fire raw material for refractory.
The utility model is to adopt following technical scheme to realize: a kind of superhigh temperature roller kilns that are used to fire raw material for refractory, comprise the kiln body, the kiln body is divided into the preheating zone, high temperate zone and salband, be provided with the thermal insulation fire-resistant layer in the kiln body of wherein high temperate zone, the thermal insulation fire-resistant layer is by top thermal insulation fire-resistant layer, bottom thermal insulation fire-resistant layer, left side thermal insulation fire-resistant layer and right side thermal insulation fire-resistant layer constitute, kiln body top, high temperate zone also is provided with furred ceiling I-shaped brick and external thermal insulation, and innovative point of the present utility model is that top thermal insulation fire-resistant layer ecto-entad is by the alumina silicate fibre blanket layer successively, high aluminum fiber blanket layer, contain that zirconium tapetum fibrosum layer makes; Bottom thermal insulation fire-resistant layer ecto-entad made by light weeight alumina brick layer, Poly Light High Aluminum Firebrick layer, JM32 brick layer, alumina hollow ball layer brick successively; Left side thermal insulation fire-resistant layer and right side thermal insulation fire-resistant layer ecto-entad successively all by alumina silicate fibre flaggy, alumina silicate fibre blanket layer, high aluminum fiber blanket layer, contain zirconium tapetum fibrosum layer, JM32 brick layer, alumina bubble brick layer and make.Above-mentioned material is existing well known materials, and the thickness of described each layer can be determined according to actual needs.
In order further to optimize the utility model structure, also done following improvement, described furred ceiling I-shaped brick adopts the one-level high-alumina brick to make, and external thermal insulation is made by the polycrystalline mullite blanket; Thermal insulation fire-resistant layer thickness in the kiln body of described high temperate zone is 650-750mm.
Adopt structural design of the present utility model, on the basis of original roller kilns, thermal insulation fire-resistant layer to its high temperate zone improves, under the prerequisite of the thickness that increases flame retardant coating, selected the higher refractory material kind of refractoriness again for use, make its refractory temperature up to 1600-1650 ℃, can satisfy the sintering process requirement of raw material for refractory fully, the refractory raw material finished material bulk density that makes is higher, water absorption rate is lower, the specification unanimity, the content's index unanimity after burning till, does not need to sieve specification, can directly be used as abrasive brick, and adopt these roller kilns can realize the continuity of whole production, and improved production efficiency, reduced production cost, the utility model has been started and will have been had roller kilns first now through being used to fire the precedent of raw material for refractory after improving, through practical proof, obtained good effect, help the exploitation and the production of refractory material homogenization material.
