A kind for the treatment of system of limestone tailing water
Technical field
The utility model relates to Wingdale process for processing field, refers to a kind for the treatment of system of limestone tailing water especially.
Background technology
In the recovery process of limestone mine, because containing earth in the ore, for obtaining to have the Wingdale finished product ore deposit of certain particle diameter and concentrate grade, often need the Wingdale raw ore of exploiting is cleaned, so can produce a large amount of tailings water.The tailings water that produces can cause serious destruction to underground water resources and surrounding enviroment, and is therefore, extremely urgent to the improvement of tailings water.
Now the processing of tailings water is often adopted natural sedimentation or adopted thickening equipment to carry out concentrating and precipitating, exist shortcomings such as length consuming time, poor processing effect, also exist resulting mine tailings after belt press filtration or filter press dehydration, because of the building stones content in the products therefrom too many, water content is higher, has directly to afforest the shortcoming of using as mine reclamation.If mine tailings directly discharge, then can increase environmental pollution, also contain the Wingdale building stones of high-quality in addition in the mine tailings, directly discharging also can cause the wasting of resources.
The utility model content
The purpose of this utility model provides a kind for the treatment of system of limestone tailing water, and stone flour, earth and moisture in the tailings water are left, thereby reaches the purpose of energy-conserving and environment-protective.
The technical solution of the utility model is achieved in that a kind for the treatment of system of limestone tailing water, comprises at least one swirler, at least one high-frequency dewatering screen, first settling tank, inhales mud scraper, second settling tank and centrifuge; Described swirler is connected with first settling tank with described high-frequency dewatering screen by conveyer respectively, and described first settling tank is connected with described second settling tank by inhaling mud scraper, and described second settling tank is connected with described centrifuge by slush pump.
Further, the diameter of described swirler is complementary with silt content in the limestone tailing water of waiting to need processing.
Further, the screen area of described high-frequency dewatering screen is complementary with silt content in the limestone tailing water of waiting to need processing.
Further, the diameter of described centrifuge is complementary with silt content in the limestone tailing water of waiting to need processing.
Further, the quantity of the quantity of described swirler and described high-frequency dewatering screen is complementary.
Further, the utility model also comprises the transition pond, and this transition pond is connected with described swirler by pump.
The beneficial effects of the utility model are: stone flour, earth and moisture in the tailings water are left; and stone flour, earth and water that separation is obtained obtain utilizing again; avoid the wasting of resources, and be beneficial to environment protection, met the relevant policies of national energy-conserving and environment-protective.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is one of them embodiment of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is treatment system synoptic diagram of the present utility model.
Among the figure: the 1-swirler, the 2-high-frequency dewatering screen, 3-first settling tank, 4-inhales mud scraper, 5-second settling tank, 6-centrifuge, 7-transition pond.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is one of them embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind for the treatment of system of limestone tailing water comprises swirler 1, high-frequency dewatering screen 2, first settling tank 3, inhales mud scraper 4, second settling tank 5 and centrifuge 6; Swirler 1 is connected with first settling tank 3 with high-frequency dewatering screen 2 by conveyer respectively, and first settling tank 3 is connected with second settling tank 5 by inhaling mud scraper 4, and second settling tank 5 is connected with centrifuge 6 by slush pump.
Wherein, the diameter of swirler 1 is complementary with silt content in the limestone tailing water of waiting to need processing; The screen area of high-frequency dewatering screen 2 is complementary with silt content in the limestone tailing water of waiting to need processing; The diameter of centrifuge 6 is complementary with silt content in the limestone tailing water of waiting to need processing.The quantity of the quantity of swirler 1 and high-frequency dewatering screen 2 is complementary, and is in time to process for the material after finishing dealing with to swirler 1, increases work efficiency.
In the utility model, also comprise transition pond 7, this transition pond 7 is connected with swirler 1 by pump.Store by collecting limestone tailing water with transition pond 7, can allow the whole course of processing continue to process, increase work efficiency.
Among the embodiment of the present utility model, the silt content in limestone tailing water is 3% o'clock, and can adopt diameter is that 600 millimeters swirler 1, screen area is 10m
2High-frequency dewatering screen 2 and the diameter centrifuge 6 that is 650mm process.Certainly, the silt content in the limestone tailing water is more high, and the screen area of the diameter of swirler 1 required selection, high-frequency dewatering screen 2 required selections can increase relatively with centrifuge 6 selected diameters, mainly is in order to guarantee processing effect and efficient.
In use, limestone tailing water can be delivered in the transition pond 7, by pump the limestone tailing water in the transition pond 7 be delivered to swirler 1, stone flour and muddy water must wet; The stone flour that will wet is processed with high-frequency dewatering screen 2, gets the drystone powder; When muddy water is transported to first settling tank 3 to solid content 10%, be drawn onto in second settling tank 5 with inhaling mud scraper 4, to solid content 〉=15% o'clock, separate to centrifuge 6 with the slush pump pump, get moulding tail mud and the water of water content≤30%.Wherein, the water that obtains of processing can recycle, and the stone flour that processing obtains can directly use, and the mud that processing obtains can be directly used in the mine reclamation greening and use.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
