Background technology
Alumina producer is auxiliary construction mines all generally, and 1 ton of bauxite of the every production of aluminous mine will produce approximately 1.5～2.0 tons of mine tailings, and the appropriate disposal of the mine tailing producing after the washup ore dressing of mine is the significant problem that is related to Sustainable Development of Enterprises.Because of the colloidal solid that bauxite washing mine tailing is a kind of fine size, viscosity is high, specific area is large, decentralization is high, deposition dehydrating difficulty, all the time, aluminous mine washing mine tailing is all built spoil disposal storehouse and is carried out wet method and store up, exist floor space large, build that storehouse investment is large, storage capacity utilization rate is low, safety and the shortcoming such as environmental protection hidden danger is large.
In wet method, store up the mine tailing mud environment pollution that once repeatedly seepage causes suspension to exceed standard in process.Nineteen ninety for spoil disposal storehouse under the plate of Pingguo repeatedly seepage cause periphery villager to drink well atmosphere pollution, there is several times leakage pollution in 2009-2012 time silver aluminum mine spoil disposal storehouse, is imposed a fine and stop production half a year by Chinese Ministry of Environmental Protection, causes larger economic loss.In June, 2013, there is mine tailing leakage accident in Guangxi Chinalco again, only speedily carries out rescue work to drop into just to spend nearly hundred million yuan.The mine tailing dry treatment that enterprise's urgent need development technique is feasible, economic and practical and comprehensive utilization technique are thoroughly to solve a difficult problem that affects Mine Safety in Production.
In addition, on the ground aluminous mine has formed a large amount of Cai Kongkeng district in the process of exploitation bauxite, is characterized in that quantity is many, depth as shallow (generally in 10m), the gross area be large.Due to the national conditions that China has a large population and a few land, goaf is made and is reclaimed after all needing outer muck haulage to fill out back and forth.On the one hand, outside is fetched earth day by day difficult, and haul distance is far away, and cost is high, and on the other hand, a large amount of mine tailing mud is stored up and taken the land resources of a large amount of preciousnesses by wet method, and forms environment pollution hidden danger.
In production practices Zhong Zhonglv Guangxi branch company (Pingguo aluminium), once explored with plate and frame type filter-press and processed mine tailing, by the filter cake producing after mine tailing press filtration for goaf reclamation, but because of mine tailing viscosity high, dewatering efficiency is low, running cost is up to 40 yuan/ton of mine tailings, and this technology fails to be widely applied.Guangxi branch company still adopts the mode of building wet method storehouse to store up Tailings Slurry at present.
Summary of the invention
The purpose of this utility model is: a kind of device with mine washing mine tailing bashing is provided, to solve existing mine washing mine tailing, generally adopt wet method to store up, and karst in karst depression extremely grows, the possibility of Tailings Slurry seepage is larger, and environmental pollution accident easily occurs; Adopt the filter cake producing after mine tailing press filtration for goaf reclamation, have the low and higher problem of running cost of dewatering efficiency.
Scheme of the present utility model is as follows: a kind of device with mine washing mine tailing bashing, comprise mud tube, chemicals dosing plant, chemical feed pipe and goaf, the port of export of mud tube passes in goaf, the drug end of chemicals dosing plant is communicated with mud tube by chemical feed pipe, is also provided with dewatering installation in goaf.
On mud tube, between the junction of mud tube and chemical feed pipe and mud tube, be also provided with mixing arrangement.
Also comprise secondary chemicals dosing plant and secondary chemical feed pipe, the drug end of secondary chemicals dosing plant is communicated with mud tube by secondary chemical feed pipe, and the connectivity part of secondary chemical feed pipe and mud tube is between mixing arrangement and the mud tube port of export, on mud tube, between the connectivity part of secondary chemical feed pipe and mud tube and the port of export of mud tube, be also provided with secondary mixing arrangement.
Mixing arrangement and secondary mixing arrangement are tube mixer.
Dewatering installation is arranged on the bottom in goaf, dewatering installation comprises draining shaft and submersible pump, on draining shaft, have inlet opening, the outer wall surrounding of draining shaft is provided with sand stone layer, the bottom at draining shaft is stretched in the suction side of submersible pump, and the outside in goaf is stretched by gutter in the water side of submersible pump.
The utility model compared with prior art, major advantage be by this device before mine tailing mud passes into goaf, in mine tailing mud, by chemicals dosing plant, add flocculant, solid particle in mine tailing mud is concentrated in together, be convenient to dehydration, pass into behind goaf, moisture enters draining shaft by the inlet opening on draining shaft, by submersible pump, water is discharged to outside, goaf again, adopt after this device, greatly improved the dehydrating effect of mud mine tailing, reduced the risk of mine tailing seepage, simultaneously, this apparatus structure is simple, operation cost is lower, adopt this device to process mine tailing, cost can be controlled in 20 yuan/ton of mine tailings.
