Red mud is that bauxite is produced remaining solid waste after aluminum oxide, its quantum of output because of ore grade, production method, state of the art different, 1 ton of aluminum oxide of every production, 1.0～1.8 tons of red muds of output simultaneously.China's aluminum oxide industry develops rapidly in recent years, and red mud is stored up in a large number, takies good farmland, and contaminate environment has become public hazards.
Along with the development of construction industry, the demand of cement is surged.Traditional cement production process is mainly taking low-grade iron ore powder as main irony additive raw material, and manufacture of cement per ton will consume the irony additive raw material (containing full Fe40% left and right) of 3%-5%.Due to iron ore for several years running price significantly rise, caused cement irony additive price soaring, the increase that has brought cement cost.Powdered iron ore price constantly rises on the one hand, cement cost improves constantly, iron red mud (containing full Fe35%-40%) needs again to expend a large amount of manpower and materials and stores up on the other hand, caused the wasting of resources, the effective irony in exploitation red mud seems particularly urgent and necessary as the development of cement additire.
There are following technological difficulties in prior art medium sand technology: (1) iron red mud viscosity is large, and moisture is high cannot directly enter cement producing line; (2) red mud water ratio 30～35%.Dry that to consume the energy large, naturally dry and take a large amount of soils, large without airborne dust after the red mud drying of curing granulation, ecological hazard is serious, and treating processes environmental requirement is high; (3) evenly to mix difficulty large with dry solidification agent greatly for wet red mud viscosity; (4) in aluminum oxide production process, for making the effective sedimentation of red mud, must add organic floculant, its effect be make red mud viscosity increase, the agglomerating sedimentation of being convenient to bonds.But processing in red mud process, because its viscosity is large, be difficult for dry and time of drying is longer.
Summary of the invention
The utility model relates to a kind of red muddy sand equipment, and the utility model is simple and reasonable, is easy to suitability for industrialized production, is less than 25% through the utility model equipment dry solidification red mud moisture after treatment, is inviscidly loose shape, is convenient to transport.
Red muddy sand equipment described in the utility model, comprise pressure filter, dry type mixer and stirrer, pressure filter connects stirrer import by red mud conveying belt, red mud conveying belt be arranged two in parallel, be respectively one-level red mud conveying belt and secondary red mud conveying belt, one-level red mud conveying belt becomes respectively 10-15 degree angle with secondary red mud conveying belt with ground, the exit end of one-level red mud conveying belt is positioned at the top of secondary red mud conveying belt, dry type mixer connects stirrer import by sand agent conveying belt, stirrer outlet connects A reactor import by compound conveying belt, A reactor outlet connects turnover throwing machine, turnover throwing machine connects second reactor import by multibuchet belt, between second reactor outlet and product packing machine, be provided with the second excavator.
For the ease of implementing, one-level red mud conveying belt becomes respectively 10-15 degree angle with secondary red mud conveying belt with ground, and because red mud water content is higher, viscosity is large, if angle is excessive, red mud can glide, so be preferably 10-15 degree angle.
Between pressure filter and one-level red mud conveying belt, be provided with the first excavator.
Sand agent conveying belt becomes 10-15 degree angle with ground, and entrance end is positioned at exit end below.
Compound conveying belt becomes 10-15 degree angle with ground, and entrance end is positioned at exit end below.
Multibuchet belt becomes 10-15 degree angle with ground, and entrance end is positioned at exit end below.
When use, red mud stirs through pressure filter press filtration, prepare red mud butt, red mud butt enters stirrer through one-level red mud conveying belt and secondary red mud tape transport under the effect of the first excavator, simultaneously by solidifying agent (calcium carbonate, magnesium oxide is in mass ratio for 5:1 mixes), the ratio that granulating agent (one or both in Calucium Silicate powder or Magnesium Silicate q-agent) and siccative (3A molecular sieve or 5A molecular sieve) are 0.5-1.5:0.05-0.2:0.01-0.02 according to mass ratio fully mixes in dry type mixer, make sand agent, sand agent enters stirrer by sand agent tape transport, the ratio that red mud butt and sand agent are 15-30:1 according to mass ratio is uniformly mixed 5-15 minute and obtains compound in stirrer, then enter A reactor by compound tape transport, in A reactor, place slaking 24-48 hour, then enter turnover throwing machine and turn over throwing, enter second reactor through multibuchet Belt Conveying again, in second reactor, place slaking 24-48 hour, then under the effect of the second excavator, entering product packing machine packs.
In sum, the utlity model has following advantage: the utility model is simple and reasonable, be easy to suitability for industrialized production, be less than 25% through the utility model equipment dry solidification red mud moisture after treatment, be inviscidly loose shape, be convenient to transport.
