A material distribution disk connected to an electrical machine is arranged in the mineral separation bin. A diameter of the material distribution disk is less than or equal to fifth of the diameter of the mineral separation bin. The material distribution disk is an umbrella shaped arc, and an upper surface of the material distribution disk is provided with a material distribution trough.
Description
Technical field
The invention belongs to the preparation equipment field, particularly a kind of proportion for choosing the ore enriched element is greater than the metallic ore of other impurity proportion in ore.
Background technology
Present domestic metallurgy industry, Metallurgical Factory's development of industry-by-industry rapidly, reached advanced international standard, but, technology in the production of the metal mining powder of one of raw material metal, processing method is also relatively backward, cause that the metal mining powder process technology falls behind, at the bottom of output, environmental pollution is large, and a large amount of waste water resource, bring huge economic loss for country and ore deposit factory, the metal mining powder of domestic production now can not meet the need of production of each large Metallurgical Factory.
Summary of the invention
The present invention is exactly for the problems referred to above, provides that a kind of output is large, expense is low, yield is high, and the pneumatic cleaner of environmental protection.
The present invention adopts following technical scheme: the present invention includes the flour mill that connected successively by feed pipe, ore dressing storehouse, spiral propeller, storage bin, deduster, its structural feature is to be provided with blower fan, air compressor on the feed pipe between flour mill and ore dressing storehouse; Described ore dressing is provided with stomatal band on the storehouse.
Described ore dressing is provided with the material separating disc that is connected with motor in the storehouse, and the diameter of material separating disc is less than or equal to 1/5 of ore dressing storehouse interior diameter.
Described material separating disc is the umbrella arc, and the upper surface of material separating disc is provided with material-dividing groove.
Beneficial effect of the present invention:
Mainly by the ore dressing of wind-force Physical, can change the drawbacks such as waste water resource in prior art, environmental pollution is large, production cost is high due to the present invention fully.Through test of many times, the useful element in ore can improve more than 40%, and take iron ore as example, iron content is by original 39%, and after one-level ore dressing storehouse screening, iron content provides 57%, and the rate of recovery reaches 80%; Through after secondary ore dressing storehouse selected, the rate of recovery reaches 98%; The waste residue that produces in ore dressing process also can be made the additive of building brick, cement; Ore separators environmentally safe of the present invention, cost is low, the rate of recovery is high, small investment, the piece that takes effect, purposes are wide, has captured the maximum difficulty that China's lean ore is many, enrichment is difficult.

The specific embodiment
The present invention includes the flour mill 1 that connected successively by feed pipe 4, ore dressing storehouse 6, spiral propeller 9, storage bin 13, deduster 15, be provided with on the feed pipe 4 between flour mill 1 and ore dressing storehouse 6 blower fan 3, blower fan 3 ', air compressor 16: be provided with stomatal band 8 on described ore dressing storehouse 6.
Be provided with the material separating disc 7 that is connected with motor 11 in described ore dressing storehouse 6, the diameter of material separating disc 7 is less than or equal to 1/5 of ore dressing storehouse 6 interior diameters.
Described material separating disc 7 is the umbrella arc, and the upper surface of material separating disc 7 is provided with material-dividing groove 14.
For utilization rate and the rate of recovery that improves breeze, it is two that ore dressing storehouse 6 can set gradually, to reach the purpose of secondary ore dressing.
For making the mineral aggregate of selecting be easy to entrucking, the exit that can be provided with the second spiral propeller 12, the second spiral propellers 12 of inclination 30-40 degree below an end corresponding with motor 10 on spiral propeller 9 is connected with storage bin 13.
Can also be arranged on Pressure gauge 5, by-pass valve control 17 on feed pipe 4 of the present invention, with better control wind-force, wind speed, improve the operating efficiency of ore dressing.
Below in conjunction with description of drawings one-off process of the present invention:
To enter in flour mill 1 by conveyer belt 2 through the ore after pulverizing with forklift, introduce in feed pipe 4 by blower fan 3 after by flour mill 1, ore being worn into breeze, to breeze be blown to ore dressing storehouse 6 by blower fan 3, increased by air compressor 16 under the situation of wind speed and pressure coordinate blower fan 3 ' suction under air passed through feed pipe 4 enter in ore separators, owing to being provided with stomatal band 8 on ore dressing storehouse 6, from the air-flow of both direction, the ore dressing storehouse 6 interior high speeds of breeze are flown in circles; Because being provided with the material separating disc 7 that is connected with motor 11 in ore dressing storehouse 6, the diameter of material separating disc 7 is less than or equal to 1/5 of ore dressing storehouse 6 interior diameters; Material separating disc 7 is the umbrella arc, the upper surface of material separating disc 7 is provided with material-dividing groove 14, in breeze flys in circles process, heavy breeze can drop in the material-dividing groove 14 of material separating disc 7 uniformly, and by dropping in spiral propeller 9 under the space between material separating disc 7 and ore dressing storehouse 6 bulkheads, slightly light breeze will be by the air intake of stomatal band 8, again is blown in ore dressing storehouse 6, thereby realizes the circulation ore dressing; By motor 10 make screw impeller 9 not section rotate heavy breeze be pushed in the second spiral propeller 12, finally enter storage bin 13.
For utilization rate and the rate of recovery that improves breeze, it is two that ore dressing storehouse 6 can set gradually, with the breeze of the light specific gravity in first ore dressing storehouse 6 will be sucked by blower fan 18 the second ore dressing storehouse 6 ' in enter ore dressing again, heavy breeze falls in spiral propeller 9 again, and light impurity sucks and drops down onto in dedusting mouth 15 by blower fan 19.
