Background

The tailings are one of products of separation operation in mineral separation, have the lowest content of useful components, are not suitable for further separation, and also become final tailings. The tailings are important resources which are generally considered to have large mining potential and high reutilization, the utilization value is high, a large amount of accumulated tailings need a large tailing pond, great environmental pollution can be caused, the tailing dam collapse accident is also easily caused, potential safety hazards are brought, and if the regeneration utilization rate of the tailings can be improved while the tailings are treated, a good promotion effect on environmental protection can be achieved.

Disclosure of Invention

The utility model provides a technical problem that will solve provides a tailing regeneration gravel aggregate system, adopt the sediment stuff pump to carry the tailing of tailing storehouse the inside to hydrocyclone, hydrocyclone arranges the tailing thick liquid after-separating to the thickener, arrange the tailing granule to the dry row of tailing sieve, the tailing is arranged the sieve to the dry row and is arranged the toper fill in the thickener after further filtering the tailing granule, arrange to portable separating centrifuge again after filtering once more through the toper fill, portable separating centrifuge separates the concentration to the tailing granule, arrange again to the pressure filter and carry out the filter-pressing and make the filter cake, process the filter cake at last again and obtain the aggregate, the cubic is concentrated and is arranged the processing to the tailing granule futilely, and water conservation, energy conservation, the reduction dust.

In order to solve the technical problem, the utility model discloses an adopted technical scheme is: a system for regenerating sandstone aggregates from tailings comprises a slurry pump, a hydrocyclone, a thickener, a movable separator, a dry tailing discharge sieve and a filter press; the hydraulic cyclone is communicated with a slurry pump and a thickener, the dry tailing discharge screen is communicated with the hydraulic cyclone and the thickener, the thickener is communicated with a movable separator, and the filter press is communicated with the movable separator.

The bottom of the movable separator is provided with a roller which is matched with the sliding rail.

The thickener is also connected with the slurry tank.

The utility model discloses a main beneficial effect mainly embodies in:

the three-stage concentration scheme combining the thickener, the movable separator and the filter press is adopted to carry out concentration and dry discharge treatment on the tailings, so that not only is the water saved, but also the dust is reduced.

In the three-stage concentration scheme, the recycling of the clean water for three times is realized, and zero emission is achieved; the finally formed tailing slurry has larger water content and is used as concrete stirring water when a tailing dam is poured.

And carrying out filter pressing on the dry-discharged tailings by using a filter press to form a filter cake, and then processing and crushing the filter cake to obtain aggregate for pouring a tailing dam.

Drawings

The following patent of the present invention is further described with reference to the accompanying drawings and examples:
