Abstract

The utility model discloses a dry separation device used for extracting fine iron powder from sand iron ores. The device comprises a screening device for screening sand iron ores and a magnetic separation device for the magnetic separation of screened sand iron ores, and is characterized in that the screening device includes a flat vibrating screen and a circular vibrating screen, and material conveying devices are mounted between the flat vibrating screen and the circular vibrating screen as well as between the circular vibrating screen and the magnetic separation device respectively. The dry separation device can greatly improve the production efficiencies of mineral separation and fine iron powder extraction, as well as the extraction quality of qualified ore particles from sand iron ores.

Description

Be used for extracting the dry separation device of the smart powder of iron from husky iron ore
Technical field
The utility model relates to a kind of ore-dressing plant, especially relates to a kind of dry separation device that is used for extracting from husky iron ore the smart powder of iron.
Background technology
Exist the abundant iron resource of total amount in the Gobi desert nefud of China's length and breadth of land, but because its ferrous grade is low, and production practice is immature, China does not build up large-scale husky iron ore exploitation base.General husky iron ore iron selection technique is directly ore deposit sand to be entered the grinding machine ball milling, and then directly enters magnetic separator and select iron, and like this, it is big to be not only the grinding machine workload, power consumption is high, the production cost height, and, the concentrate iron powder taste of selecting is low, does not reach the basic demand of steel mill, basic not value.And at present from husky iron ore, extracting the various device that the smart powder of iron uses, especially to dry separation stage of husky iron ore, its production efficiency and all lower to the extraction quality of qualified ore particles in the husky iron ore.
Summary of the invention
Technical problem to be solved in the utility model has provided and a kind ofly can improve production efficiency that the smart powder of ore dressing and iron extracts greatly and to the dry separation device that is used for extracting from husky iron ore the smart powder of iron of the extraction quality of qualified ore particles in the husky iron ore.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of dry separation device that is used for extracting from husky iron ore the smart powder of iron, comprise the screening plant and the concentration equipment that is used for husky iron ore after sieving is carried out magnetic separation that are used to sieve husky iron ore, it is characterized in that: described screening plant comprises plane vibration sieve and the round sieve that shakes, described plane vibration sieve and circle shake and are provided with device for transporting objects between the sieve, and described circle shakes and is provided with device for transporting objects between sieve and the concentration equipment.
Described concentration equipment is two roller dry-type magnetic extractors.
Described plane vibration sieve is installed on compass screen surface and the described plane vibration screen vibrator that is used for intermittent control shaking on the described support by comprising support.
The described circle sieve that shakes comprises the support underframe, is installed on the screen box of described support underframe by spring damper, rotates the circle that is installed on the described screen box screen vibrator that shakes, and described support underframe is provided with the vibrator power set that are used to drive described vibrator.
The described circle screen vibrator that shakes comprises eccentric block and the eccentric shaft that is connected described eccentric block.
Described device for transporting objects is the conveyer belt that is driven by power set.
Plane vibration sieve and the round sieve that shakes that this dry separation device that extracts the smart powder of iron from husky iron ore cooperatively interacts by employing, husky iron ore is carried out elder generation's screening back dry separation, can successively there be ore dressing to be worth particle during use by plane vibration sieve and round twice screening of sieve jettisoning that shakes, removed most of mine tailing, significantly reduced and extracted smart next step production cost of powder of iron in the husky iron ore, obtain qualified concentrate particle such as the following particle of 5mm, carry out magnetic separation by two roller dry-type magnetic extractors again, the semi-finished product concentrate taste after the magnetic separation is brought up to about 13% by about 7%.Plane vibration sieve adopts and is provided with on compass screen surface the intermittent control shaking vibrator and can guarantees that sieve screen apertures is unimpeded and do not stop up, and improves screening efficiency.It is simple and practical that the round screen vibrator that shakes adopts eccentric shaft to add the eccentric block formula, good to the vibrating effect of screen cloth.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Fig. 1 is the structural representation that the utility model is used for extracting from husky iron ore the dry separation device of the smart powder of iron;
Fig. 2 is the utility model circle sieve structure schematic diagram that shakes.
The specific embodiment
As depicted in figs. 1 and 2, a kind of dry separation device that is used for extracting the smart powder of iron from husky iron ore, comprise the screening plant and the concentration equipment 3 that is used for husky iron ore after sieving is carried out magnetic separation that are used to sieve husky iron ore, screening plant comprises plane vibration sieve 1 and the round sieve 2 that shakes, plane vibration sieve 1 and circle shake and are provided with device for transporting objects 4 between the sieve 2, circle shakes and is provided with device for transporting objects 4 between sieve 2 and the concentration equipment 3, and concentration equipment is two roller dry-type magnetic extractors.Device for transporting objects 4 can be conveyer belt type structure such as the belt conveyor that is driven by power set.And plane vibration sieve is by comprising support, is installed on compass screen surface on the support and is used for the plane vibration screen vibrator of intermittent control shaking, and plane vibration screen vibrator intermittent control shaking on compass screen surface guarantees that sieve screen apertures is unimpeded not stop up, and improves screening efficiency.
Two roller dry separation magnetic separators mainly comprise support, and being installed on the support one, to select cylinder, two to select cylinder, reductor, motor and magnetic be compositions such as guiding mechanism.After plane vibration sieve 1 and round sieve 2 screenings of shaking, the raw ore of release mesh is delivered to two roll machine by device for transporting objects and is carried out magnetic separation, through magnetic separation, obtains half higher concentrate of grade, most of defective mine tailing of skimming again.
The circle sieve that shakes comprises and supports underframe 21, is installed on the screen box 23 that supports on the underframe 21 by spring damper 22, rotates the circle that is installed on the screen box 23 screen vibrator 25 that shakes, and supports underframe 21 and is provided with and is used to drive the shake vibrator power set 24 of screen vibrator 25 of circle.Screen box 23 adopts ring-grooved rivet to connect, and forms tower structure, and the round screen vibrator 25 that shakes comprises eccentric block and the eccentric shaft that is connected eccentric block, and vibration absorber adopts steel coil springs.Circle circle that the motion of sieve has eccentric mass by vibrator power set 24 as motor by the V-belt driving screen vibrator 25 that shakes that shakes, eccentric shaft by eccentric block makes screen box 23 produce vibration, the movement locus of screen box 23 is circular, and the screen cloth granularity is interchangeable as requested.
