Abstract
The invention relates to a raw material ratio for producing energy-saving bricks by coal gangue as well as a preparation method of the energy-saving bricks. The preparation method is characterized by mixing 40% of coal gangue, 25% of clays, 15% of water granulated slag, 10% of construction waste, 5% of sands and 5% of chemical elements (such as carbon dioxide, aluminum oxide and ferric oxide) in percent by weight; crushing block objects such as coal gangue and construction waste; then, mixing and squeezing and moulding the mixture; cutting to green bricks and placing in an annular kiln; after drying, firing for 2-4 hours at 900-1050 DEG C to prepare a finished product. The preparation method has the positive effects that coal gangue slag waste in coal gangue can be effectively utilized to produce the energy-saving sintered bricks with excellent performance; as the coal gangue has a certain heat value, so that coal is saved for preparing the bricks, and waste heat can be utilized. The obtained bricks have the characteristics of light weight, sound insulation, heat insulation, thermal insulation, are lower than national standard in radioactive index and applicable to energy-saving buildings, and have the advantages of short production period, simple process and energy-saving production.
Description
Technical field
The present invention relates to building materials field, is mainly a kind of proportioning raw materials of utilizing coal gangue production energy-saving brick and preparation method thereof.
Background technology
Vitrified brick is risen in China, propagates into the whole world, so far the history of existing 7300.Because vitrified brick making is simple, easy to use, have higher intensity and endurance quality, most countries is all usingd vitrified brick as topmost materials for wall in the world at present.No matter China or foreign country, now or in the future, vitrified brick can not change as the general layout of main materials for wall, and output also increases with annual 20% speed.But tradition take solid clay brick that clay is main raw material exist size little, in vain great, production energy consumption is high and the shortcoming of occupying a large amount of arable lands.The enterprise of most of brickmaking when the time comes will face existence predicament.Therefore the research and extension of accelerating novel energy-conserving vitrified brick has very important economy and social effect.
Therefore, the method can effectively be utilized bastard coal rock ballast refuse in coal ore, produces the energy-saving clinker brick of excellent property.The one, coal gangue discharge capacity is very large, abundant raw material.A large amount of discharges of coal gangue, accumulation, not only occupy farmland, and contaminate environment, as with these coal gangue instead of clay brickmaking, not only can save soil, and can save and process human and material resources, the financial resources that these barren rocks spend.The 2nd, because coal gangue has certain thermal value, with this brickmaking, can accomplish to be sparing in the use of coal, can do UTILIZATION OF VESIDUAL HEAT IN, for the needs of producing and living simultaneously.The 3rd, the feature of utilizing making coal gangue brick to there is technique compactness, can produce throughout the year, not be affected by climate change, mechanize and the automatization of for brickmaking, producing provide favourable condition.The 4th, colliery wastes brick stable performance, outward appearance are good, technology maturation.Colliery wastes brick color even, clear; Ultimate compression strength is high, generally at 100～150kg/c ㎡; Folding strength is also higher, generally at 23～50 ㎏/c ㎡.It not only possesses the performance of common brick, and is better than in many aspects common brick, meets the standard of promulgated by the ministries or commissions of the Central Government of building materials completely.At present, colliery wastes brick is used widely in Industrial and Civil Engineering.The 5th, can enjoy the relevant preferential tax policy of government.Utilize making coal gangue brick, belong to " three wastes " comprehensive utilization, there is preferential tax policy in country to this.
Summary of the invention
The object of this invention is to provide a kind of proportioning raw materials of utilizing coal gangue production energy-saving brick and preparation method thereof, can effectively utilize bastard coal rock ballast refuse in coal ore, produce the energy-saving clinker brick of excellent property.
The technical solution used in the present invention is: invention relates to a kind of proportioning raw materials of utilizing coal gangue production energy-saving brick and preparation method thereof, it is characterized in that:
A, by weight percentage, coal gangue accounts for 40%, and clay accounts for 25%, and grain slag accounts for 15%, and building waste accounts for 10%, and sand accounts for 5%, and chemical composition element accounts for 5% (element such as silicon-dioxide, aluminium sesquioxide, Indian red) to be mixed;
B, the bulk objects such as coal gangue, building waste are crushed to the particle of 0.05mm-2mm, then are mixed, mixture extrusion moulding, cut into adobe, put into annular kiln, after drying, at the temperature of 900-1050 ℃, fire 2-4 hour, make finished product.
Described is a kind of proportioning raw materials of utilizing coal gangue production energy-saving brick and preparation method thereof, it is characterized in that: drying mode is to put into annular kiln, utilizes the waste heat of baking bricks to be dried;
Positively effect of the present invention is: can effectively utilize bastard coal rock ballast refuse in coal ore, produce the energy-saving clinker brick of excellent property.That this brick has is lightweight, sound insulation, heat insulation, insulation, radioactive indicator be lower than national standard, the feature of suitable construction energy-saving building thing; And have with short production cyclely, technique is simple, the advantage of production energy-saving.
Below by embodiment, invention is further described:
Embodiment:
Embodiment 1:
Take off by weight percentage the raw material of row mass ratio: the coal gangue of 40 kilograms, the clay of 22 kilograms, the grain slag of 15 kilograms, the building waste of 10 kilograms, the sand of 5 kilograms, the chemical composition element silicon-dioxide of 8 kilograms mixes;
Embodiment 2:
Take off by weight percentage the raw material of row mass ratio: the coal gangue of 40 kilograms, the clay of 25 kilograms, the grain slag of 15 kilograms, the building waste of 10 kilograms, the sand of 5 kilograms, the chemical composition element aluminium sesquioxide of 5 kilograms mixes;
Then the coal of described embodiment 1 and embodiment 2 quality proportionings is crushed to the bulk objects such as coal gangue, building waste to the particle of 0.05mm-2mm, then is used biaxial rneader and mixing extruder to be mixed into pug.
By the brick press extrusion moulding of gained pug, cut into after adobe, pile, in annular kiln, utilizes annular kiln waste heat humidity discharging, dry again, finally with annular kiln, at 1000 ℃, fires 2-4 hour, makes finished product.
Because the effect of every kind of chemical element is different respectively, when making, can add according to different needs various chemical elements.
