The iron mine tailing dry pile device comprises a system which is formed by a whirlcone, a drainage screen and a deep cone thickener and a pressure filter. A bottom flow outlet of the whirlcone is communicated to a material inlet of the drainage screen through a pipeline, a minus sieve material of a hopper outlet of the drainage screen is communicated to a material inlet of the whirlcone through a pipeline, and a plus sieve material of an overflow port of the drainage screen is conveyed to a dry pile field through a belt conveyor. An overflow port of the whirlcone is communicated to the material inlet of the deep cone thickener through a pipeline, a bottom flow outlet of the deep cone thickener is communicated to a material inlet of the pressure filter, a material at a discharging port of the pressure filter is conveyed to the dry pile field through the belt conveyor, and overflow of the deep cone thickener and overflow of the pressure filter are returned to a dressing mill and continuously used as backwater. The iron mine tailing dry pile device is small in occupied area, high in utilization rate of water resources, safe and reliable. Meanwhile, equipment such as the whirlcone is used to separate tailing into a dry material and water through a dry pile process device to a greatest extent, the dry material in accordance with water content is conveyed to a tailing storage yard to store, and the water is used as backwater of the dressing mill.
Description
Technical field
The utility model relates to the adopting iron ore tailings treatment facility field in the mining industry, relates in particular to the dried stack device of a kind of adopting iron ore tailings.
Background technology
In line form is adopted in present domestic most metal mine tailings dischargings, processing method system adopts traditional waterpower conveying method to enter Tailings Dam, because a large amount of tailings (wetting) are piled up ground, the one, take a large amount of soils, increase habilitation scale and Tailings Dam operation cost; The 2nd, have a strong impact on ecological environment, cause environmental disruption; The 3rd, Tailings Dam extremely easily produces potential safety hazard, easily causes landslide or mud-rock flow, has the dam break risk.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, provide that a kind of floor space is little, water resource utilization efficiency is high, the dried stack device of safe and reliable adopting iron ore tailings, utilize the equipment such as cyclone by doing the heap process unit Tailings Slurry to be realized that the maximization of siccative and water separates, the siccative that reaches the water content requirement is transported to tailings stack and stores, and water then can be used as the ore dressing plant recycling water utilization.
The utility model is achieved through the following technical solutions:
The dried stack device of a kind of adopting iron ore tailings, include the system that cyclone, dewatering screen, deep wimble thickener and filter press form, it is characterized in that: the underflow opening of described cyclone is by the charging aperture of pipeline communication to dewatering screen, the undersize material of the hopper outlet of described dewatering screen is by the charging aperture of pipeline communication to cyclone, and the on-the-sieve material of described dewatering screen overfall is transported to dried stockyard by belt conveyer; The overfall of described cyclone is by the charging aperture of pipeline communication to deep wimble thickener, the underflow opening of described deep wimble thickener is by the charging aperture of pipeline communication to filter press, the material of the discharge port of described filter press is transported to dried stockyard by belt conveyer, and the overflow of described deep wimble thickener and filter press overflow are returned as backwater and selected factory to recycle.
Described belt conveyer is two, and is obliquely installed respectively in the below of the upper discharge gate of dewatering screen sieve and filter press discharge port.
Its principle is: will at first enter cyclone from the tailings (concentration is about 10-15%) in ore dressing plant, after cyclone is concentrated, the material concentration of underflow opening reaches 65%-70%, directly enter dewatering screen by pipeline, the material concentration of the on-the-sieve material underflow opening of dewatering screen reaches more than 80%, water content is transported to dried stockyard by belt conveyer again below 15%; Undersize material returns the cyclone feed, and namely cyclone and dewatering screen form a simple closed-circuit system, guarantees that dry material is by the dewatering screen output.The material of the overfall of cyclone enters secondary concentration in the deep wimble thickener, and the overflow of deep wimble thickener is returned as backwater and selected factory to use, and the underflow of deep wimble thickener enters filter press, and the material of the discharge port of filter press is transported to dried stockyard by belt conveyer.
The utility model has the advantages that:
1, this device pluses and minuses of prior device of having sublated, as utilize dewatering screen to replace traditional adhesive tape filter or a minute bucket is processed the cyclone underflow.Keeping simultaneously hydrocyclone--the concentrator serial flow is the part of technique as a whole, adopts at last filter press to process thickener underflow, realizes the fully dried row of tailings.
2, this device is to coarse fraction in the Tailings Slurry and all pointed processing of fine particle stage material.Utilize cyclone to realize that large or fine granule separates, coarse granule is processed by dewatering screen.The cyclone underflow is done the heap effect still undesirable in the situation that concentration reaches 65%-70% for adopting iron ore tailings, utilize dewatering screen to process the cyclone underflow, can further improve underflow density, makes it to reach more than 80%.Simultaneous pumping undersized product to cyclone forms closed-circuit system, and backwater is obtained by filter press and concentrator.
3, the cyclone overflow feeds concentrator, can overcome concentrator overflow race muddy, greatly alleviates the pressure of concentrator treating capacity.Be conducive to improve the concentration of enriched product, reduce the concentrator diameter, save the space, place.Adopt flocculant, thickener underflow concentration reaches about 45% very soon, does not do the heap requirement but reach.Adopt filter press to process thickener underflow, when obtaining clarifying backwater, can further reduce material water ratio, reach and do the heap requirement.Owing to only needing to process fine particle stage material, reduced the filter press treating capacity simultaneously, number of units capable of reducing using is saved cost.
In sum, after tailings was processed through this device, the siccative coarse grain was by obtaining on the dewatering screen sieve, particulate is obtained by filter press, can reach and well do the heap effect, the backwater of concentrator and filter press output directly returns and selects factory to recycle, and the backwater rate is brought up to more than 95% by original 60%.(according to traditional water that enters Tailings Dam, because factors such as evaporations, seepage, approximately there is 15% water can not return use.Adopt tailing dry-heaping, this part water is directly used flow process, can reduce new water consumption, improve water application efficiency).
