Abstract
The invention relates to a method for preparing a fly ash porcelain granule, which comprises materials and proportions thereof and a production technical process, wherein according to the material proportions, 85 to 95 percent of fly ash, 1 to 10 percent of coal dust and 0 to 10 percent of clay are prepared into 1 to 2 percent of 0.5 to 0.05 percent combustion improver solution; the technical process comprises the following steps: stirring the materials to prepare a mixture; spraying a combustion improver solution to the mixture; rolling the mixture to prepare a porcelain granule ball blank; screening the blank and roasting the blank in a kiln for 1.0 to 1.5 hours; cooling the blank until the temperature is 600 DEG C and then taking the blank out of the kiln; and cooling the blank naturally to obtain the finished product of the fly ash porcelain granule. Because the mixture is doped with a small amount of the coal dust and the combustion improver solution agglutinates the mixture to form the porcelain granule ball blank, all inflammable components contained in the porcelain granule ball blank can be burnt sufficiently, is not only advantageous to improve the burning efficiency, reduce the cost, shorten the roasting time and improve the production efficiency, but also overcomes the situations that in the prior art, the fly ash porcelain granule has different colors and different hardness degrees, thereby providing a basic guarantee for the fly ash porcelain granule to be used in building decorative materials.
Description
Technical field
The present invention relates to building materials manufacturing technology field, particularly a kind of method of making lytag.
Background technology
Flyash is that a kind of heat power plant etc. is with the very big waste residue of coal rich and influential family quantity discharged; Big or small heat power plant and other consumption coal enterprise of various places spreads all over the country; All producing a large amount of flyash every year, handles and utilize means owing in the past it is had no, and therefore becomes the contaminate environment product; Existent environment of people has been caused serious harm, also caused heavy burden simultaneously to enterprise.How flyash is turned waste into wealth; Second stage employ in addition; Be that the degree of reducing the burden on enterprises, reduce the flyash environmental pollution is a major issue of benefiting the nation and the people; Receive the concern and the attention of the whole society, the technical scheme and the achievement of some effective processing flyash that come out at present, " lytag and the working method " for example announced in No. 98104779.3 patent of China " production of non-sintered porous flyash and ceramsites blocks " announced and No. 200610042562.8 patent; Their common feature is earlier flyash to be processed haydite, then Application and Development in addition as required.Because the material of lytag is inexhaustible and sintering process in do not need too many fuel; Thereby it is with low cost; Finished product has characteristics such as light weight, intensity be high, pollution-free, radiationless; In order to a large amount of natural gravel, yellow ground cement and the natural claies etc. that use of institute in the manufacturing that replaces existing building materials and in the building operation, can bring to alleviate the buildings deadweight, reduce construction costs and improve the positive technique effects such as antidetonation, sound insulation, heat-insulating property of buildings, market demand rises day by day.But because the ME of lytag still belongs to the exploratory stage at present; Thereby the ubiquity formula variation is big, constant product quality property difference and output are put forward not high many drawbacks; So work hard aspect reasonableness, product quality stability and the High-efficient Production of necessary prescription at lytag, to meet the need of market.
Summary of the invention
The objective of the invention is to provide a kind of science of selecting materials, reasonable ratio, help improving the method for manufacturing lytag of quality product and the output of lytag.
The method of manufacturing lytag of the present invention includes two aspects, first material and proportioning, and it two is technological process of productions.
The material that the present invention makes lytag includes flyash, coal dust, clay and ignition dope, and wherein ignition dope is to comprise combustion-supporting agent for fuel coal, boiler auxiliary combustion agent or combustion promoter for diesel oil in interior commercially available chemical industry solvent product, and weight proportion is following:
Flyash 95%;
Coal dust 1%;
Clay 2%;
Ignition dope 2% (obtain solution concentration is 0.5%-0.05%);
ME is following:
With flyash, coal dust, clay measure in proportion drop in the stirrer fully stir, uniform mixing, form mixture;
2. with ignition dope thin up to concentration the solution of 0.5%-0.05%;
3. mixture is added in the pan-pelletizer of pan-type pelletizer, and upwards spray ignition dope solution, roll and process haydite ball base;
4. use sieve aperture to sieve as the vibratory screening apparatus of 0.8mm;
5. the haydite ball base that will after sieving, stay is sent into roasting in the sintering oven, 1450 ℃ ± 50 ℃ of sintering temperatures, and roasting time 1.5 hours finishes the back below stove internal cooling to 600 ℃, and kiln discharge, naturally cooling are processed the lytag finished product then.
In addition, described ME all can operation according to the order of sequence on production line, accomplish automatically; Described sintering oven can be have continuous batch charging incessantly, the uninterrupted type of production kiln of discharging functions in batches.
Make the method for lytag based on the present invention of above-mentioned design; With flyash is major ingredient; Be aided with have bonding, accelerate hardening and clay, coal dust and ignition dope combustion-supporting, ignition function, and, help all contained in haydite ball base inflammable materials owing to be mixed with a small amount of coal dust, ignition dope in the mixture and process behind the band aqueous solution form with tackiness agent with the form of water mixing dilution and be sprayed at and make it bonding balling-up on the mixture; Original composition that do not fire comprising in coal dust and the fly ash material can both be fully burned; Both improved efficiency of combustion, saved the fuel consumption in the stove, and helped reducing production costs; Help again quickening to reach temperature, shortening roasting time, more help guaranteeing the quality of ceramic product and enhancing productivity.In addition; Also owing to the carbonaceous component in the haydite ball base is fully burned in whole roasting process; Make that the lytag finished product color and luster that after roasting, forms is more approaching, performance reaches unanimity; Quality guarantees easily, can not take place that the lytag color and luster differs in the prior art, the situation of hard degree varies.In sum; The method of manufacturing lytag of the present invention has high quality materials and science, proportioning is suitable and technical maturity and rationally; Help guaranteeing the quality product and the scale operation of lytag, have tangible technical advance, remarkable economical property and very strong practicality.
