Description
Technical field
The present invention relates to the device of mine washing tailings dewatering, belong to the Tailings Disposal technical field in mining production.
Background technology
The general all auxiliary construction mines of alumina producer, aluminous mine often produces 1 ton of bauxite by generation about 1.5 ~ 2.0 tons of mine tailings, and the appropriate disposal of the mine tailing produced after the washup ore dressing of mine is the significant problem being 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.
The once repeatedly seepage environmental pollution that causes suspension to exceed standard of mine tailing mud in process is stored up in wet method.Nineteen ninety for spoil disposal storehouse under the plate of Pingguo repeatedly seepage cause periphery villager to drink well atmosphere pollution, 2009-2012 time silver aluminum mine spoil disposal storehouse there is leakage pollution several times, imposed a fine by Chinese Ministry of Environmental Protection and stop production half a year, causing 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 the difficult problem affecting Mine Safety in Production.
In addition, aluminous mine defines a large amount of Cai Kongkeng districts in the process of exploitation bauxite, is characterized in that quantity is many, depth as shallow (generally within 10m), the gross area are large.Due to the national conditions that China has a large population and a few land, reclaim after all needing outer muck haulage to fill out back and forth in goaf with making.On the one hand, fetch earth difficulty day by day in outside, 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 by wet method and taken a large amount of valuable land resource, and soil boy structure pollution hidden trouble.
Once explored with plate and frame type filter-press process mine tailing in production practices Zhong Zhonglv Guangxi branch company (Pingguo aluminium), the filter cake produced after tailings characteristic is used for goaf reclamation, but because of mine tailing viscosity high, dewatering efficiency is low, operating cost is high, and this technology fails to be widely applied.Current Guangxi branch company still adopts the mode of building wet method storehouse to store up Tailings Slurry.If the tailing dehydrating device that a kind of dewatering efficiency is high, operating cost is low can be researched and developed, the dry mine tailing after dehydration is used for the comprehensive utilizations such as mine worked-out section filling or brickmaking, by the larger economic benefit of generation and social environment benefit.
Summary of the invention
The object of the invention is to: the combination unit that a kind of tailings dewatering is provided, to solve existing mine washing mine tailing deposition dehydrating difficulty, general employing wet method is stored up, exist floor space large, build that storehouse investment is large, storage capacity utilization rate is low, the problem of safety and the shortcoming such as environmental protection hidden danger is large.
The solution of the present invention is as follows: a kind of combination unit for tailings dewatering, comprise centrifuge, feed pipe and chemicals dosing plant, the discharge end of feed pipe passes in centrifuge, also comprise mud regulating tank and mixer, the working end of mixer is stretched in mud regulating tank, the feed end of feed pipe is connected with the bottom of mud regulating tank, and the medicine outlet end of chemicals dosing plant is stretched in mud regulating tank.
Feed pipe is provided with valve.
Described centrifuge is horizontal spiral formula centrifuge.
Described centrifuge is provided with discharge outlet and slag-drip opening.
The water side of discharge outlet is stretched in water leg.
On described centrifuge, the below of slag-drip opening is provided with conveying device.
Described conveying device is Shaftless screw conveyor, and the feed end of conveying device is arranged on centrifuge immediately below slag-drip opening, and conveying device tilts upward setting by feed end to discharge end.
The present invention compared with prior art, major advantage adds as flocculation medicaments such as polyacrylamides in mud regulating tank by chemicals dosing plant, mine tailing mud and flocculation medicament being mixed in mud regulating tank passes in centrifuge again, thus make mine tailing mud realize dehydrating and curing in centrifuge, without the need to building the spoil disposal storehouse being used for wet method and storing up, overcome conventional wet and store up the land occupation that mine tailing brings, the drawback of contaminated environment, thus realize Economization on land, reduce and store up investment, reduce enterprise operation cost, reduce the target of tailings impoundment risk and protection of the environment, good economic benefit can be obtained, meanwhile, the solidification mine tailing after dehydration also can be used for the reclamation of mine worked-out section, reduces reclamation cost, produces larger economic benefit and social environment benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
For making object of the present invention, technical scheme and a little clearly, below in conjunction with accompanying drawing, the present invention is described in further detail.
Composition graphs 1, embodiments provides a kind of combination unit for tailings dewatering, comprising:
Comprise centrifuge 1, feed pipe 2 and chemicals dosing plant 5, the discharge end of feed pipe 2 passes in centrifuge 1, also comprise mud regulating tank 6 and mixer 7, the working end of mixer 7 is stretched in mud regulating tank 6, the feed end of feed pipe 2 is connected with the bottom of mud regulating tank 6, the medicine outlet end of chemicals dosing plant 5 is stretched in mud regulating tank 6, feed pipe 2 is provided with valve 3, centrifuge 1 is horizontal spiral formula centrifuge, described centrifuge 1 is provided with discharge outlet 8 and slag-drip opening 9, the water side of discharge outlet 8 is stretched in water leg 12, on centrifuge 1, the below of slag-drip opening 9 is provided with conveying device 14, described conveying device 14 is Shaftless screw conveyor, the feed end of conveying device 14 to be arranged on centrifuge 1 immediately below slag-drip opening 9, conveying device 14 tilts upward setting by feed end to discharge end.
Described conveying device 14 is preferably Shaftless screw conveyor, the feed end of conveying device 14 to be arranged on centrifuge 1 immediately below slag-drip opening 9, conveying device 14 tilts upward setting by feed end to discharge end, the discharge end place of conveying device 14 can arrange conveying arrangement such as transport vehicle 15 grade, by conveying arrangement, the solidification mine tailing after dehydration is transported, because mine can form a large amount of Cai Kongkeng districts in the process of exploitation mineral products, therefore, solidification mine tailing after dehydration can be used for the reclamation of mine worked-out section, there are two aspect benefits herein: on the one hand, the outside reclamation carrying out goaf that fetches earth is day by day difficult, haul distance is far away, cost is high, the reclamation adopting the solidification mine tailing after dehydration to be used for mine worked-out section greatly reduces the cost of reclamation, on the other hand, a large amount of mine tailing mud is stored up by wet method and is taken a large amount of valuable land resource, and soil boy structure pollution hidden trouble, and mine tailing slurry dewatering is converted into solidification mine tailing and water, solidification mine tailing is used further to reclamation, stores, and eliminate pollution hidden trouble without the need to land occupation.
