Abstract
The present invention relates to a kind of gravity method mineral concentration technology. It is suitable for extracting concentrate ore powder from low grade metal ore and colllecting the tails for reuse and causing no pollution. Said winnower provides a circulating wind force from an induced draft fan to make the ore power be separated into different specific weight concentrated ore under the blowing actin while the ore powder entering the sizing bucket. Compared with the prior methods for mineral separation, the advantages of said invention are having no need of adding any material, small floor space, low energy consumption, easy operation, directly collecting the tails for construction use.
Description
The present invention relates to a kind of heavy method ore-dressing technique, utilize the different specific weight of the difference generation of tenor in the ore exactly, rely on wind-force to sort out the needs that fine ore reaches pyrogenic process or hydrometallurgy.
Since the dawn of human civilization, the exploitation in mine is protected expensive mineral resources and also destroyed regional vegetation in loss because economic aspect or technical elements do not add utilization and arbitrarily abandon it low-grade ore.The ore dressing plant that also has present China generally all is an abrasive dust after adopting disintegrating machine to ore reduction, substantially be to continue to use traditional heavy method, float glass process and magnetic method to extract concentrate, though it is very high to get the ore deposit rate, but also have a lot of metallicses to be drained in the mine tailing, take very big stacking place, wasted mineral resources.And traditional ore-dressing technique be unable to do without water and many chemical assistants.Everything has all caused pollution very big to environment.
Purpose of the present invention is exactly at above-mentioned phenomenon, provides that a kind of cost is low, comprehensive benefit is high, can fully extract the fine ore in poor value and the ore dressing plant tail sand; Can directly reclaim mine tailing, and be applicable to the preparation equipment that uses under any regional climate condition.
The object of the present invention is achieved like this: a kind of pneumatic cleaner that extracts fine ore from metallic ore is made up of the circulation air path that air-introduced machine, motor, screening bucket and each position have different functions of use, and its characteristics are that whole ore dressing process finished by the circulation wind-force that an air-introduced machine provides.For the breeze of different cultivars and different required precisions, regulate by the branch pole plate that pneumatic jig bar and discharging opening top to horizontal distribution in the screening bucket are provided with, the precision of breeze is improved more than 30 times, collect simultaneously mine tailing with comprehensive utilization.
Advantage of the present invention: 1. adopt pneumatic separation, do not add water and chemical assistant, do not cause environmental pollution; 2. working power is few, and applicable variety is wide, and ore dressing precision height has reduced smelting cost; 3. floor space is little, and it is simple, easy to operate changing complicated ore-dressing technique; 4. can directly reclaim mine tailing and be used, the overall economic efficiency height; 5. using widely, is to use as usual in high and cold icing area; 6. cost is low, raw material sources are many, has administered contaminated environment again when the tailing in old mine and ore dressing plant is processed, and mineral resources are fully used.
Below in conjunction with accompanying drawing the present invention is described in further detail:
Fig. 1 is an apparatus and process flow chart of the present invention, also can be used as the specification digest accompanying drawing.
Fig. 2 sieves the structural map of bucket for the present invention: 1. air-introduced machine; 2. blast pipe; 3. feed hopper; 4. flat axle; 5. motor; 6. screening struggles against; 7. split pole adjusting rod; 8. concentrate discharging opening; 9. middle breeze discharging opening; 10. tailing discharging opening; 11. dust ash discharging opening; 12. quiet wind dust-settling compartment; 13. induced duct; 14. hanger bar; 15. pneumatic jig bar; 16. precision adjusting rod.
Pneumatic cleaner of the present invention is as a kind of heavy method preparation equipment, made full use of the different specific weight that is had because of the tenor difference in the breeze, when fineness is that 100-200 purpose breeze is when falling into the screening bucket of high-frequency vibration by charging aperture, the breeze of different quality has produced different fallings speed under the wind-force effect, that is to say little being blowed of proportion forward, heavyly then fall quickly, the breeze that mixes different specific weight when falling into the pneumatic jig bar has obtained initial gross separation.The screening bucket of pneumatic cleaner is made up of the pneumatic jig bar of multilayer horizontal distribution, the pneumatic jig bar is designed to the inequilateral triangular form, its one side of facining the wind is the abrupt slope of 60 degree, the vibrations of high frequency make heavy metal mining powder bullet accelerate from the abrupt slope to fall when the breeze coasting, the breeze little with proportion spreads out, and helps obtaining wind-force when falling into lower floor's pneumatic jig bar and sorts.Pneumatic jig bar one side with the wind is the gentle slope of 25-30 degree, fall into top breeze heavy metal mining powder under high-frequency vibration and can pass the mineral powder laminating on domatic, because metal mining powder is than great, domatic resistance is little, therefore gliding speed is fast than other breeze, is more easily sorted by wind-force when falling into lower floor's pneumatic jig bar.Like this through the reciprocation of wind-force and pneumatic jig bar, the mineral powder after the multilayer selection by winnowing extracts fine ore after by minute pole plate classification.At this moment, be in the middle middle breeze that contains the little metal ore deposit of concentrate and mine tailing and return feed hopper, continue selection by winnowing and go out fine ore.The raw material that mine tailing then can be used as cement or ceramic tile directly loads and transports.
Claims (5)
1, a kind of pneumatic cleaner that extracts fine ore from the low-grade metal ore deposit is to adopt heavy method ore-dressing technique, and by air-introduced machine, screening bucket, circulation air path are formed, it is characterized in that need not be by traditional waterpower or medicine, but utilizes wind-force to finish ore dressing work.When breeze entered winnowing machine screening bucket, under the effect that blows of wind-force, the mineral powder that proportion is little was sent to heavy metal mining powder forward then more directly toward the whereabouts by wind-force, and when falling into the pneumatic jig bar of lower floor, the different metal mining powder of proportion just obtains sorting.After the pneumatic jig bar sorting through the multilayer distribution, the tailing collection bucket that the mineral powder that proportion is little is delivered to the place ahead by winnowing is discharged, and heavy metal mining powder becomes fine ore and obtains extracting below the screening bucket.
2, a kind of pneumatic cleaner that from the low-grade metal ore deposit, extracts fine ore according to claim 1, air inducing when it is characterized in that air-introduced machine work is made up of the circulation air path of fuselage inner sealing with air-supply, fast 2～3 times than other position of the wind speed when sending into the screening bucket.
3, a kind of pneumatic cleaner that extracts fine ore from the low-grade metal ore deposit according to claim 1 is characterized in that described screening bucket device has flat axle, by producing flat 0.15 centimetre after the motor drives, and the frequency shake that per minute is 700-1000 time.
4, according to claim 1 and 3 described a kind of pneumatic cleaners that from the low-grade metal ore deposit, extract fine ore, it is characterized in that described screening bucket by the multilayer horizontal distribution can before and after the triangular form pneumatic jig bar regulated forms, the one side of facining the wind of pneumatic jig bar becomes 60 to spend abrupt slopes with level; One side becomes the slope of 25-30 degree with level with the wind.
5, a kind of pneumatic cleaner that extracts fine ore from the low-grade metal ore deposit according to claim 1 is characterized in that being provided with in the circulation air path quiet wind dust-settling compartment and dust discharge gate.
