Description

Electrolytic manganese waste residue sintered type composition brick and manufacture method thereof
Technical field
The present invention relates to building materials, building brick specifically, the sintered type composition brick that more specifically utilizes electrolytic manganese waste residue to manufacture, and manufacture method.
Background technology
Electrolytic manganese waste residue quantum of output is about 8 ~ 10 times of Electrolytic Manganese Product, while utilizing low lean ore up to 10 ~ 15 times.The main component of electrolytic manganese waste residue is calcium sulfate, sal epsom, ammonium sulfate, silicate and manganous sulfate in liquid tailings processed, ironic hydroxide etc., and these wastes are slightly acidic, process badly will cause severe contamination to environment.
It is a difficult problem that electrolytic manganese waste residue is processed.Being used for of having manufactured unburned steam pressure cement brick, but cost is too high, is difficult for applying.What have is used for manufacturing cement, but waste residue consumption is few, can not effectively consume a large amount of waste residues that electrolytic manganese industry produces.
CN102731040A discloses a kind of method of utilizing electrolytic manganese waste residue to prepare building block brick series product, describedly utilizes building block brick series product prepared by electrolytic manganese waste residue to be made by mass percentage by following raw material: modification electrolytic manganese waste residue 20%-50%, fine aggregate 10%-20%, coarse aggregate 30%-49%, cement 8%-30%, properties-correcting agent 0.001%-0.005% and water 10%-15%.Its modification electrolytic manganese waste residue comprises stone coal powder, coal powder, volcanic ash, unslaked lime, and fine aggregate comprises calcite in powder, ground silica ground dolomite, marble flour, and formula is complicated, and product cost is higher.
Summary of the invention
The object of this invention is to provide a kind of electrolytic manganese waste residue sintered type composition brick.The present invention simultaneously also provides the method for manufacturing electrolytic manganese waste residue sintered type composition brick.
Electrolytic manganese waste residue sintered type composition brick of the present invention, is made by the main material of following weight parts, 30 ~ 50 parts of electrolytic manganese waste residues, 5 ~ 20 parts of coal gangues, 5 ~ 20 parts, shale, 10 ~ 30 parts of clays.
Preferably scheme is, 40 ~ 50 parts of electrolytic manganese waste residues, 10 ~ 15 parts of coal gangues, 10 ~ 15 parts, shale, 15 ~ 25 parts of clays.
Best, 45 parts of electrolytic manganese waste residues, 10 parts of coal gangues, 15 parts, shale, 20 parts of clays.
In order to ensure the safety in utilization of electrolytic manganese waste residue sintered type composition brick, the electrolytic manganese waste residue that the present invention uses should meet the requirement of GB5085.3-2007.
In order to utilize by poor manganese high ferro manganous carbonate and Manganse Dioxide, adopt direct leaching to prepare the waste residue that electrolytic manganese produces, the present invention also by such waste residue for the preparation of electrolytic manganese waste residue sintered type composition brick.
The electrolytic manganese waste residue that the present invention uses, while considering electrolytic manganese production, the fineness of waste residue is enough thin, so do not need just can directly drop into through pulverizing.But from products production requirement of the present invention, the fineness of general requirement electrolytic manganese waste residue between 80 ~ 100 orders for well.
The manufacture method of electrolytic manganese waste residue sintered type composition brick of the present invention, comprises ageing after powder process, batching, stirring, stirs.Described powder process is that coal gangue, shale, clay are beaten respectively to powder to fineness is 1 ~ 5mm, is preferably 2 ~ 3mm.After batching, stir, digestion time 24 ~ 96h; After ageing, need to stir again.
Preferred version is: digestion time 36 ~ 72h after stirring.Better scheme is digestion time 48h after stirring.
Electrolytic manganese waste residue contain heat 200 ~ 300 card/gram, enough internal combustion heats can be provided.Be conducive to save external putting-in coal consumption consumption, save and bake bricks with fuel, cost-saving.
Electrolytic manganese waste residue fineness 80 ~ 100 orders, without beating powder can directly come into operation (being less than 2 ~ 3mm that coal gangue and shale are played powder requirement).Therefore can save powder process cost.In addition, can also improve a raw material material grating, improve the plasticity index of batching, guarantee Forming Quality.
The metal contents such as the iron in electrolytic manganese waste residue, aluminium, calcium, magnesium, can improve the hardness of brick product.Coal gangue contain heat 700 ~ 800 card/gram, interior heat is provided, be also conducive to save external putting-in coal consumption consumption.And coal gangue sintering brick product has porous, energy-conservation, high-strength and decoration complex function.
Shale is as light collection frame material, and the product of producing has that body is light, insulation, the feature such as energy-conservation.Adopt this product as building masonry wall material, can realize building energy conservation.
Technical scheme of the present invention can be processed electrolytic manganese waste residue in a large number.And the perforated brick hardness high quality producing is good, as its radioactivity of material of construction and toxicity aspect, meets safety requirements.
The manufacture method of electrolytic manganese waste residue sintered type composition brick of the present invention, presses roasting method, belongs to internal combustion brick.Coal gangue and electrolytic manganese waste residue are flammable industrial wastes, and when adobe is fired to after certain temperature in kiln, the fuel combustion porcelain in base substrate is formed brick.Internal combustion brick has been saved a large amount of external putting-in coals than external burned brick, the clay 5% ~ 10% that economizes in raw materials, and intensity improves 20% left and right, the apparent densification of brick, sound-insulating performance strengthens.
In the manufacture method of electrolytic manganese waste residue sintered type composition brick, ageing is to utilize each material molecule to interpenetrate to make each composition naturally reach uniform process.Because electrolytic manganese waste residue is enough tiny, so can reduce digestion time.
At technical process, processing parameter and use production unit machine context, method of the present invention is also according to routine.
Technical scheme of the present invention, Easy dosing, sintering process consumption coal is few, so beat the few little power consumption of powder amount, the equipment loss of reduction pulverizing process, the feature such as made product has light weight, and hardness is high, and production cost is low.
