Abstract
The present invention discloses a magnetic separator for treating tailings, consisting of base seat, support wheel, fixed cylinder, rotary cylinder, protecting cover, feeding funnel and powder-receiving hopper. It is mainly characterized by that the magnetities are mounted on the inner wall of the mixed cylinder, and semi-circularly distributed on the cross-section of the fixed cylinder, the rotary cylinder is placed in the fixed cylinder, and its inner wall is equipped with helical baffle plates, and two end portions of the rotary cylinder are connected with support wheel placed on the base seat, and said support wheel can provide powder by means of driving device, two ends of the fixed cylinder are equipped with protecting cover respectively, and on the protecting covers the feeding fu9nnel and powder-receiving hopper are connected.
Description
Technical field: the invention belongs to the technique of preparing field, relate to a kind of magnetic separator of handling tail sand.
Background technology: the present patent application people's on-the-spot investigation the some little ore dressing point in counties such as Qianxi, Qian'an, Zunhua, Kuan Cheng, the Green Dragon, find that it all is the water magnetic separator of the outer suction formula of tradition that the there is handled the husky green grass or young crops of tail of the same colour, generally from tail sand, extract one ton of iron powder and need water consumption 40-60 ton, and run tail still at 2.8-3.4%, so both caused the mineral resources waste, cause water resource waste again, but also bring environmental pollution.Chinese patent CN2269905Y disclosed " permanent magnet dry type automatic iron removing magnetic separator " and CN2130111Y disclosed " superfine material dry type purification magnetic separator ", they all provide possibility for the dry operation of magnetic separation.But, because the former is " powder is realized sorting at the air-gap field passage ", the latter is by " the inner core swing separates magnetic and namagnetic substance ", this just must cause their structurally complicated and have problem on the performance, thereby has influenced and apply.
Summary of the invention:
The objective of the invention is: at the defective and the deficiency of prior art, a kind of magnetic separator of handling tail sand is provided, it is not only dry operation, and suction mode in adopting, and has simple in structure, easy to operate, high efficiency, purification rate height simultaneously, saves advantages such as water source, non-environmental-pollution.
Technical solution of the present invention is: a kind of internal adsorption dry magnetic separator, form by base, support roller, safety barrel, rotating cylinder, protective cover, feed hopper, powder-receiving hopper etc., it is characterized in that: safety barrel is fixedly supported on the base, and rotating cylinder places in the safety barrel, and its both ends connect with support roller on being located at base; Wherein, the inwall of safety barrel is provided with magnetite, and this magnetite is semi-circular distribution on the cross section of safety barrel, and the inwall of rotating cylinder is provided with dividing plate, and this dividing plate is shape distribution in the shape of a spiral on the inwall of rotating cylinder; The both ends of safety barrel are provided with protective cover, and wherein the protective cover first line of a couplet of an end taps into hopper, and connect the front portion of powder-receiving hopper, and the rear portion of powder-receiving hopper is connected on the protective cover of the other end.
The operation principle of this magnetic separator is, support roller drives the rotating cylinder rotation under the driving of power, and after tail sand entered rotating cylinder, along with the rotation tail sand of rotating cylinder will produce Radial Flow, promptly tail sand moved upward along barrel.At this moment, because the effect of safety barrel inwall magnetic force, iron powder wherein will be attached on the drum wall, and when rotating cylinder forwarded no magnetic region to, iron powder will come off and fall in the powder-receiving hopper; And waste material wherein (sand) is because the character of self and the effect of gravity, rollback downwards when it rises to certain height, and along with helical baffle travels forward vertically, up to the outflow rotating cylinder.So realize sorting purposes.
Compared with prior art, magnetic separator provided by the invention has following advantage:
(1) because this magnetic separator adopts the neodymium iron boron magnetite, have stronger attraction,, operate steadily in addition so separation performance is reliable, thereby high efficiency, the husky 20-30 ton of tail per hour can be handled; The sorting index height facts have proved, by the tail sand of this magnetic separator single treatment, it runs tail and has only 0.5-1%, if again through after-treatment, then resource utilization is close to 100%.
(2) this magnetic separator did not both have the branch of " main separation ", " helping choosing " device, again need not pendulous device, only, can realize continuous disposable sorting by simple circular motion; Its magnetite is distributed as the bar shaped magnetite and directly is adsorbed on the safety barrel inwall, and has only a circumference mostly, and not only loading and unloading are easy, and reduce cost; Its feed hopper, powder-receiving hopper are suspended structure, and its power adopts motor, engine all can.Thereby simple in structure, processing ease.
(3) the same with other dry-type magnetic extractors, the work of this machine does not need water, and the wet type wet concentration equipment that extensively adopts in producing than reality had so both been saved the water source, non-environmental-pollution again, and its application scenario will not be subjected to water and environmental limit, thereby be more convenient for applying.
Description of drawings:
Fig. 1 is the internal adsorption dry magnetic separator structural representation, and B-B analyses and observe.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment: the present invention is elaborated below in conjunction with accompanying drawing.
Show among the figure, this magnetic separator partly is made up of base, support roller, safety barrel, rotating cylinder, protective cover, feed hopper, powder-receiving hopper etc., it is characterized in that: safety barrel 5 is fixedly supported on the base 1, and rotating cylinder 7 places in the safety barrel 5, and the both ends of its rotating cylinder connect with support roller 2 on being located at base 1.The external transmission device of supporting-roller shaft provides power, and support roller drives the rotating cylinder rotation.The inwall of safety barrel 5 is provided with magnetite 6, and magnetite 6 is a NdFeB material, and Pork-pieces magnetite 6 is semi-circular distribution on the cross section of safety barrel 5, that is to say that magnetite does not take the circumference of safety barrel 5.The inwall of rotating cylinder 7 is provided with dividing plate 8, and this dividing plate 8 is shape distribution in the shape of a spiral on the inwall of rotating cylinder 7, and promptly this dividing plate is a helical baffle.Here, establish semi-circular magnetite in the safety barrel, establishing helical baffle in the rotating cylinder is the key measure that the present invention realizes the internal adsorption dry magnetic separation.The both ends of safety barrel 5 are provided with protective cover 4, and wherein feed hopper 3 just connects at one end the protective cover, on the protective cover of feed end, and connect the front portion of powder-receiving hopper 9, and its rear portion then is connected on the protective cover of the other end.In addition, on feed hopper, also be provided with plate, so that the control inlet amount.
This magnetic separator is except being used to handle the tail sand, and the dry type that also can be used for various superfine materials is purified.
