Description
Technical field
The present invention relates to vitrified brick technical field, be specifically related to a kind of natural pond liquid vitrified brick and preparation method thereof.
Background technology
Peace and development is the two principal themes of the world today, but along with the raising day by day of social development, living standards of the people, town and country Municipal Garbage Yield constantly increases, and composition is increasingly sophisticated, its harm is also more and more serious, and rubbish has become the focus of global concern as worldwide public hazards.For alleviating urban refuse pollution, the comprehensive regulation of rubbish and the research work of utilization are all devoted in countries in the world.The processing of municipal wastes is an integral part of environment protection, is worth further our deep discussion.
Along with the development of industrialization and urbanization, environmental problem has caused global attention.In the evolution of urbanization, town and country rubbish has been beaten alarm bell to people.In recent years, the generation total amount of China's domestic waste increases considerably.First this increase relevant with China city quantity; The increase of city size and urban population is also major cause.Airborne remote sensing is measured and is shown, the above scrap heap in 50 square metres of Beijing suburb just has more than 7000.China's application of city life garbage day output is 0.7～1.0kg per capita, and increases with average annual 10% speed.Large, medium and small city (town), whole nation generation approaches 200,000,000 tons.So the processing to municipal wastes is compeled at the tip of the brow.
But in China, the utilization ratio of rubbish is but very low, the big cities such as Beijing and Shanghai are only 1～5%.At present, some big or middle cities only adopt the mode processing of simple landfill, have not only wasted resource, and take a large amount of soils, polluted source and environment, harm people's health.Research shows, the organic content of China's domestic waste is the trend increasing year by year in recent years, and in organic waste, is rich in the nutrient elements such as nitrogen, phosphorus, potassium, is good organic fertilizer raw material.If it is made full use of, in alleviating carrying capacity of environment, also can solve China's soil and be badly in need of the matter of great urgency of a large amount of organic fertilizer.
In China's town and country rubbish, also have much can second stage employ resource, if the organism in domestic refuse is after anaerobically fermenting produces biogas, can how remaining waste be processed, again utilize, and also becomes one of focus of present social concerns.
Summary of the invention
The object of the present invention is to provide a kind of natural pond liquid vitrified brick, the present invention also aims to provide the preparation method of a kind of natural pond liquid vitrified brick, utilize organic waste remaining waste after anaerobically fermenting to carry out roasting brickmaking through solid-liquid separation gained natural pond liquid, make rational use of resources, save brick making cost.
In order to realize above object, the present invention adopts following technical scheme:
A kind of natural pond liquid vitrified brick, described vitrified brick is prepared from by following component by weight percentage: clay 75～85%, coal gangue 14～24%, natural pond liquid 0.5～2%, described natural pond liquid be organism in domestic refuse after anaerobically fermenting produces biogas, remaining waste is through solid-liquid separation gained liquid.
Preferably, described vitrified brick is prepared from by following component by weight percentage: clay 80%, coal gangue 19%, natural pond liquid 1%.
A preparation method for natural pond liquid vitrified brick, comprises the following steps:
(1) material storage and pre-treatment:
Take by weight percentage following raw material: clay 75～85%, coal gangue 14～24%, natural pond liquid 0.5～2%, clay and coal gangue are pulverized, then add natural pond liquid, stir it is mixed;
(2) ageing
The mixtures of materials that step (1) is mixed is delivered in ageing storehouse and carries out ageing, and described digestion time is 60～80 hours;
(3) moulding
Step (2) is delivered to fitting room through the mixtures of materials of ageing, enters again two-stage vacuum extruder for blocks extrusion moulding through mixing extruder, fine cracking double roller machine, obtain base substrate;
(4) drying and roasting
The base substrate drying car that step (3) is obtained is sent into kiln and is dried, described time of drying 65～85min, described drying temperature is 170～190 DEG C; Then dried base substrate is sent into tunnel furnace and carry out roasting, described roasting time is 65～85min, and described maturing temperature is 850～1050 DEG C.
Preferably, the clay in described step (1) and the pulverizing of coal gangue adopt jaw crusher, hammer mill, three grades of fragmentations of fine cracking double roller machine, and after pulverizing, granularity is less than 1.5mm.
Preferably, the whipping process in described step (1) adopts biaxial rneader to stir.
Preferably, in described step (2), digestion time is 72 hours.
Preferably, in described step (4), be 75min time of drying, and drying temperature is 180 DEG C, and roasting time is 75min, and maturing temperature is 950 DEG C.
Vitrified brick provided by the present invention, requires the abundant homogenizing of raw material, ageing, and production technique is had relatively high expectations to material performance, stricter to raw material processing, and equipment is also had higher requirements.Therefore, technological design emphasis has been strengthened raw material processing, green brick forming and dry, and concrete preparation process is as follows:
(1) material storage and processing
This production line adopts the discarded natural pond liquid producing in garbage processing procedure to join in the conventional raw material clay of vitrified brick and coal gangue to carry out vitrified brick preparation.For raw material is fully mixed, production technique adopts jaw crusher, hammer mill, three grades of fragmentations of fine cracking double roller machine, just broken rear granularity is controlled in 20mm, after hammer crushing crusher machine, particle diameter is less than 3mm, be less than 1.5mm by granularity after fine cracking double roller machine, after mixture fragmentation, enter double-shaft stirrer stirring and mix, it is mixed.
(2) ageing
The mixture of processing through step (1) can contain certain moisture, and ageing is carried out in mass transport to ageing storehouse, makes on the one hand the abundant homogenizing of raw material, increases the plasticity of raw material; On the other hand, the continuity of producing is played and regulated and shock absorption.Digestion time is 60～80 hours.
(3) extrusion moulding
Multi-bucket excavator, endless belt conveyor for mixtures of materials after ageing are transported to fitting room.Fitting room is by box feeding machine feed, and material enters two-stage vacuum extruder for blocks extrusion moulding again through mixing extruder, fine cracking double roller machine, obtains base substrate, and forcing machine main frame is selected the molding device of condition of high vacuum degree, high extrusion pressure.
