Abstract
The present invention discloses a coal gangue sintered brick. The coal gangue sintered brick consists of the following components in proportion by weight: 70-75% of coal gangue; 10-15% of emulsion waste oil; 2-5% of silica fume or cement; and 10-13% of water. The present invention further discloses a method for preparing the coal gangue sintered brick. The method comprises the following steps of: preliminary crushing, smashing, screening, mixing, stirring, aging, secondarily stirring, carrying out vacuum extruding, slitting, carrying out brick-body molding, drying, sintering, and cooling. According to the coal gangue sintered brick and the preparation method therefor disclosed by the invention, the coal gangue and the emulsion waste oil are used as main raw materials for brick preparation, so that not only can cultivated lands and land resources be saved, but also damages to vegetation and river environment can be avoided; and produced bricks have good plasticity, better bearing capability, good water permeability, andare energy-saving and environmentally-friendly.
Description
Technical field
The invention belongs to difference or as the preparation of admixtion or the technical field of process raw material, specifically relate to a kind of coal gangue sintering fragment of brick and preparation method thereof.
Background technology
The traditional brick-making technology of China utilizes vitrified bond brickmaking, it need exploit arable land in a large number, farmland is caused to destroy, therefore a lot of enterprise starts to utilize other materials etc. to replace or partly replace clay, flyash in such as industrial waste or coal gangue etc., the development of National Industrial causes the quantity discharged sharp increase of industrial waste, not only take a large amount of places, and contaminate environment, in order to reduce the clay consumption of brickmaking industry, accelerate flyash, the recycling of the industrial wastes such as coal gangue, a lot of brickmaking enterprise starts to utilize flyash, coal gangues etc. produce vitrified brick, the rise of real estate in addition, when not only needing to remove, produce a large amount of building waste residues, and when digging ground, also the large batch of earthwork is produced, these building waste residues and the earthwork are many times used to dump rubbish field or riverbank or along the river, occupy a large amount of land resources and the destruction to vegetation and fluvial-environment, China is as iron and steel output big country in addition, emulsion waste oil drop on rolling mill production line is a great problem as pollution treatment, emulsion waste oil drop contains a large amount of iron powders, emulsion composition, hydraulic oil composition and oil formulation, existing emulsion waste oil drop adopts landfill and dries and paves the way etc., not only cause land wastage, and waste resource.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of coal gangue sintering fragment of brick and preparation method thereof, this coal gangue sintering fragment of brick and preparation method thereof makes full use of coal gangue and emulsion waste oil drop as brick-making raw material, not only can farmland saving and land resources, avoid the destruction to vegetation and fluvial-environment, and the floor tile plasticity produced is good, pressure-bearing better, good water permeability, energy-conserving and environment-protective.
In order to achieve the above object, a kind of coal gangue sintering fragment of brick of the present invention, its component and weight ratio are:

The invention also discloses a kind of method preparing coal gangue sintering fragment of brick, its concrete steps are as follows:
(1) use hammer mill to carry out preliminary break process to coal gangue, after broken, particle size controls at 1 ~ 10mm;
(2) preliminary broken rear particle is entered twin rollers and carry out pulverization process, after pulverizing, particle enters flow screen, and after sieve, particle size controls at 1mm;
(3) after saying sieve, particle, emulsion waste oil drop, silicon ash or cement and water proportionally drop into stirrer, and carry out stirring and make pug, then carry out ripening, the time is more than 24 hours;
(4) compound after ageing is stirred 0.5 ~ 1 hour again, adopt vacuum extruder, slitting shear machine by again stir after compound extrude, make adobe;
(5) adobe is piled up in brickkiln, concentrate humidity discharging dry;
(6) sintering oven is put in dried adobe to sinter, cool to obtain finished product.
Further, in step (5), cool and send into brick kiln drying after 3 ~ 10 hours, bake out temperature is 400 ~ 600, and drying time is 2 ~ 3 hours, and adobe water ratio is 5 ~ 10%.
Further, in step (6), sintering temperature is 900 ~ 1000 DEG C, and sintering time is 3 ~ 5 hours, 18 ~ 30 hours storage periods.
Beneficial effect of the present invention is:
1, coal gangue sintering fragment of brick of the present invention and preparation method thereof makes full use of coal gangue and emulsion waste oil drop as brick-making raw material, not only can farmland saving and land resources, avoid the destruction to vegetation and fluvial-environment, and the floor tile plasticity produced is good, pressure-bearing better, good water permeability, energy-conserving and environment-protective.
2, coal gangue sintering fragment of brick of the present invention utilizes iron powder, hydraulic efficiency oil and the oil formulation in emulsion waste oil drop, makes itself and coal gangue mixed sintering, is conducive to the intensity improving knot brick.
