Description
Technical field
The invention belongs to building material field, be specifically related to a kind of method of producing blue bricks watt.
Background technology
Blue bricks watt carries the unique and thick and heavy architectural aesthetic orientation of the Chinese nation, and giving plain, simple and unsophisticated and quiet aesthetic feeling, is that irreplaceable material of construction repaired by a lot of newly-built building in the style of the ancients and ancient building.Although blue bricks intensity, difference of hardness compared with common brick is few in addition, the performance in anti-oxidant, aquation, atmospheric corrosion etc. is better than common brick.
During firing brick-and tile, the ferro element in adobe material during roasting, makes product take on a red color under oxidizing atmosphere, and under reducing atmosphere roasting time, make product be cyan or grey.Produce traditional method many uses water chestnut kiln of blue bricks to fire, exist energy consumption high, pollute the shortcomings such as large and production efficiency is low.
The technology of blue bricks watt produced by the use tunnel furnace that occurs in recent years, the primary process of producing is: entrucking enters kiln-preheating-oxidizing roasting-reducing roasting-water-spraying control-naturally cooling-kiln discharge, and reducing roasting wherein and water-spraying control link are the key links making the finished product present cyan.For avoiding the brick and tile base through reducing roasting at high temperature again oxidized and making the finished product take on a red color, the method displacement air that usual employing is sprayed water in firing chamber and make brick and tile base be cooled to safety temperature about 400 DEG C under oxygen-free atmosphere, then be placed in general air ambient and be cooled to kiln discharge.The shortcoming of this method is that speed of cooling and uniformity coefficient are wayward, and water has infringement to brick and tile base and kiln.
For the shortcoming of water-spraying control, patent 93109410.0 proposes the method for another kind of cooling brick and tile base, the method arranges gas passage between tunnel furnace preheating zone malleation place and cooling zone afterbody, uses the gas of deoxidation to form circulation in preheating zone and cooling zone thus realizes the object of anoxic cooling brick and tile base.The shortcoming of the method is that the tightness of gas circulation requires higher, and the oxygen in recycle gas is not easily removed completely, and brick and tile base secondary oxidation may occur.
Patent 200710111254.0 proposes the Processes and apparatus that blue bricks watt produced by another kind tunnel furnace, and its technological process is: dress base enters tunnel furnace-preheating-oxidizing roasting-high temperature kiln discharge-cover upper inverted bell-reducing roasting-anaerobic cooling-naturally cooling-unload cover-kiln discharge.Its technical essential carries out reducing roasting by passing into the mixed gas that Sweet natural gas and the ratio of air are 2: 7 after the brick and tile base cover upper inverted bell of oxidizing roasting, in bell jar, then passes into the mixed gas that nitrogen and the ratio of Sweet natural gas are 9: 1 carry out anaerobic cooling.In bell jar, separately establish cooling line, cold wind can be passed in cooling line and bell jar environment is cooled indirectly.The shortcoming of the method in bell jar, passes into nitrogen when being cooling brick and tile base and sky hot gas adds production cost, production technique more complicated.
Summary of the invention
For prior art Problems existing, the invention provides a kind of method of producing blue bricks watt, object makes production process more simple and easy to do, reduces production cost simultaneously.
The technical scheme realizing the object of the invention is carried out according to following steps:
First preheating is carried out in the preheating zone that dried brick and tile base kiln car is loaded into tunnel furnace, the brick and tile base after preheating enters roasting band and carries out roasting;
Roasting band wicket is opened after roasting terminates, kiln car pull-out is entered discrete material and throws in district, being fallen by kiln car cover covers on kiln car, discrete material dispensing port is provided with on the top of kiln car cover, throw in discrete material by discrete material dispensing port to enter in kiln car cover, and be covered in around brick and tile base, on the downside of described kiln car cover, be provided with nozzle of calming the anger, in kiln car cover, spray non-oxidizing gas, make discrete material be filled in space between brick and tile base;
After covering discrete material, open cooling zone lifting wicket, kiln car is drawn in cooling zone, is separated by discrete material after cooling with brick and tile base, obtaining outward appearance is caesious blue bricks watt product.
In described roasting process, different according to product requirement, oxidizing roasting is first carried out to the brick and tile base after preheating and carries out reducing roasting, directly roasting or directly roasting in reducing environment in an oxidizing environment again.
When described covering material is covered in around brick and tile base, by vibration, waves kiln car or in kiln car cover, carry out mechanical agitation and lift and make discrete material be filled in space between brick and tile base.
The another kind of mode of described covering discrete material is, brick and tile base is unloaded from kiln car, be placed in cooling tank, one deck discrete material is spread in advance bottom cooling tank, then in cooling tank, throw in discrete material be covered on brick and tile base, then the cooling tank immigration cooling zone covering discrete material is cooled.
Described discrete material is flyash, mine tailing, haydite, bastard coal rock ballast, slag, sand or rubble, and described mine tailing comprises iron tailings, gold tailings, copper tailing;
Described discrete material is preheating to 200 DEG C ~ 800 DEG C and carries out thermal pretreatment before input.
Particulate or powdery combustiblematerials can be added in described discrete material.
Compared with prior art, feature of the present invention and beneficial effect are:
The present invention produces blue bricks watt, lower than traditional water chestnut kiln production energy consumption, pollute little, production efficiency is high, adopting discrete material as heat-eliminating medium, and to cool without the need to spraying water in firing chamber, the speed of cooling and the uniformity coefficient of cooling are easy to control, and avoid the infringement of water to brick and tile base and kiln;
The present invention forms gas circulation without the need to using depleted gas in preheating zone and cooling zone, tightness is less demanding, effectively can avoid the secondary oxidation of brick and tile base, the present invention without the need to carrying out reducing roasting and anaerobic cooling in airtight bell jar, also do not need to arrange cooling line to cool the environment closed, production technique is relatively simple.
The present invention is when discrete material selects flyash or bastard coal rock ballast, because discrete material itself is containing a certain proportion of carbon component, at high temperature consume the oxygen in discrete material gap and generate carbon monoxide and carbon dioxide, make to be in reducing atmosphere around brick and tile base, and control the speed of cooling of brick and tile base by exothermic heat of reaction.Additionally can also add the combustiblematerialss such as a certain amount of coal dust, bastard coal rock ballast, wood chip in addition, to regulate generation and the generation speed of carbon monoxide and carbonic acid gas, be controlled the speed of cooling of brick and tile base by exothermic heat of reaction simultaneously.For the discrete material not containing combustiblematerials composition, also the combustiblematerialss such as a certain amount of coal dust, bastard coal rock ballast, wood chip can additionally be added, to regulate generation and the speed of generation of carbon monoxide and carbonic acid gas, controlled the speed of cooling of brick and tile base by exothermic heat of reaction simultaneously.Also thermal pretreatment is carried out to discrete material in the present invention, the speed of cooling of brick and tile base can be avoided so too fast, thus make the contraction process of brick and tile base slack-off, improve the quality of blue bricks watt product.
