Description

SPIRAL AND MAGNETIC SEPARATOR [0002]

The present invention relates to separation of materials from a mixture using property differences, and more particularly to a device for separating beneficial minerals from clastic resources such as sand.

Useful minerals such as ilmenite, rutile, zircon, monazite, magntite and hematite are used as essential raw materials in various industries. In other words, in the case of titanium oxide, it is used as a welding rod, a special magnetic material or an ultraviolet shielding pigment, and zircon is used for ceramics, high-grade bearing, and ball mill.

In the case of the aforementioned minerals, almost all of the minerals depend on imports. Recently, the prices of these minerals have been relatively low, but they were very expensive a few years ago. Minerals are often priced by policy issues, unlike general market supplies and demands, such as mineralization of resources, restrictions on transactions for the protection of the domestic industry. In other words, the price is not stable and shows a rapid change.

For example, the price of monazite was $ 2,700 per ton, and that of zircon was $ 900 per ton. As a result, it is necessary to develop rare mineral resources in Korea without relying on imports, but they are failing to achieve effective results.

On the other hand, it is being investigated that the sand in the river side and the coast in Korea, such as lecturer and sea shore, contain useful minerals such as titanolite and monazite. That is, 1.5% of lecturers and maritime workers are made up of the minerals mentioned above. According to the Ministry of Land in 2014, the fine aggregate is expected to be produced and supplied at about 36 million tons / year except for the aggregate of aggregate, and it is reported that the lecturers will be developed and used as construction materials. There are about 10,000 tons of useful minerals, and the economic value of these minerals is almost 500 billion. Accordingly, development of a technique for recovering useful minerals from maritime or lecturers is being demanded.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a specific gravity force sorter which separates usable minerals from separated clastic resources.

On the other hand, other unspecified purposes of the present invention will be further considered within the scope of the following detailed description and easily deduced from the effects thereof.

In order to accomplish the above object, the present invention provides a non-gravity-force sorter for separating the beneficial minerals from a liquid mixture containing a clay minerals comprising water-soluble minerals and components having different magnetic and specific gravities, and water A spiral body provided with an inlet portion through which the optical fluid flows and a channel portion spirally arranged so that the optical fluid flowing into the inlet portion flows downward while rotating, and an outlet portion through which the optical fluid flows out, And a partition wall member disposed in the outlet portion so that the light liquid flowing out through the outlet portion of the spiral body can be separated into a plurality of branches according to the specific gravity so that the heavy mineral water is distributed to the inner portion of the outlet portion, A specific gravity separating unit for discharging to the outside of the part; And

And a magnetic force separating unit disposed next to an inner side of the outlet portion of the specific gravity separating unit and pulling out the magnetic substance out of the heavy light to the innermost portion of the outlet portion.

According to the present invention, at least two or more of the partition members are spaced apart from each other along the width direction of the channel portion so that the light liquid passing through the outlet portion can be divided into at least three halves, and the magnetic heavy- It is discharged along the innermost limb.

In one embodiment of the present invention, the magnetic force separation unit is rotatably installed along the traveling direction of the optical fluid. Preferably, the magnetic force separation unit is rotated on a vertical plane. However, according to the embodiment, the magnetic force separation unit may be rotated on a horizontal plane.

The non-magnetic-force separator according to the present invention can separate a light mineral, a heavy magnet, and a magnetic body mineral through a single process using a spiral-type specific-gravity separation unit and a magnetic force separation unit using a magnet to be rotated. Particularly, it is possible to classify magnetic and non-magnetic materials from heavy metals containing a large amount of useful minerals. This has the advantage that the sorting process is very fast and simple.

In addition, there is an advantage in that the object to be separated can be selected according to the properties of the clastic resource to be treated by controlling the intensity of the magnet.

The accompanying drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

The present invention relates to a sorting apparatus for sorting and screening beneficial minerals from scalding resources such as lecturers and marine personnel. Here, clumsy resources are resources that have already been separated. In the process of beneficiation of traditional resource development, minerals containing minerals containing minerals are mined into rocks and then crushed and crushed using crushers or the like. Since the majority of gangue minerals are combined with a small number of useful minerals, the gangue minerals and the beneficial minerals are separated from each other when the particle size is reduced through crushing. Thereafter, only the beneficial minerals are separated using the difference in properties between the gangue minerals and the beneficial minerals. The efficiency of shredding and shredding in the entire process of resource development also determines the economics of resource development.

However, the present invention does not require a crushing and crushing process in the process of resource development. Sand is a product of weathering of rocks for a long time because it is already separated from the group. The advantage of minerals is less in comparison with ore, but the development cost of clinker resources is attractive because development costs are significantly reduced. Moreover, the economic benefit can be further improved because the sand after separating the beneficial minerals can be reused as aggregate, which is construction and civil engineering material.

In particular, rare earth minerals such as rare earths are contained in sand, and overseas advanced countries are spurring resources development by separating and sorting sand.

The present invention has also been derived in this context in order to separate useful minerals from sand using the difference between the specific gravity and magnetic properties of the sand component and the useful minerals mixed in the sand.

The main object of the present invention is sand, but it is not limited to sand only and can be expanded to clastic resources which are already separated from each other.

Hereinafter, a magnetic force specific gravity sorter according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic perspective view of a specific gravity separator according to an embodiment of the present invention, FIG. 2 is a schematic plan view of a main portion of FIG. 1 in an unfolded state, and FIG. 3 is a schematic side view of FIG.

Referring to FIGS. 1 to 3, the non-gravity-force sorter 100 according to an embodiment of the present invention includes a specific-gravity separation unit 50 and a magnetic force separation unit 60.

The specific gravity separating unit (50) has a main body (10) and a partition wall member (20).

The main body 10 serves as a channel through which a mixed solution of sand and water containing beneficial minerals flows. The main body 10 is formed to be long along the vertical direction, and has an inlet 11 through which the light is introduced, And an outlet portion 12 through which the liquid is discharged is provided on the lower side. A channel portion 13 is provided between the inlet portion 11 and the outlet portion 12. A support rod 30 is fitted at the center of the spiral body 10 to support the body 10.

The channel portion 13 of the main body 10 is separated along the vertical direction so that the liquid can be separated by the specific gravity in the process of flowing the liquid to the inlet portion 11 of the spiral body 10 and flowing out to the outlet portion 12. [ It is formed into a spiral shape. That is, since the light having flowed into the inlet 11 flows toward the outlet 12 side while rotating along the spiral-shaped channel portion 13, the particles having a small specific gravity in the light liquid due to the centrifugal force, The particles having a large specific gravity are remained on the inner side along the width direction of the water passage portion 13. The light mineral proceeds along the outcourse of the water channel section (13), and the heavy lantern proceeds along the innose of the water channel section (13).

As shown in FIG. 2, the light fluxes reaching the outlet portion 12 through the channel portion 13 are gathered with heavy particles x on the inner side along the width direction of the water channel portion 13, Light particles (y) are gathered.

In general, beneficial minerals contained in the sand have a higher specific gravity than the constituents of the sand, so that beneficial minerals are concentrated inside the outlet portion 12.

A partition wall member 20 is installed in the outlet portion 12 to separate and discharge the optical fluid sequentially arranged along the width direction of the water channel portion 13 by a specific gravity. In the present embodiment, two partition members 20 are disposed along the width direction of the outlet portion 12, and the optical fluid is separated and discharged in three directions according to the specific gravity. Needless to say, two or more of the partition members may be arranged in order to separate the optical fluid more finely.

A guide member 40 having a plurality of guide tubes 41 is provided at the outlet 12 of the spiral body 10 so that the plurality of mutually separated optical fluids separated by the partition member 20 can be discharged to the outside, As shown in FIG. A discharge tube 42 is connected to each guide tube 41 to guide the optical fluid to a predetermined reservoir (not shown).

On the other hand, as described above, the specific gravity separation unit 50 separates them from each other according to the specific gravity difference between the sand component and the beneficial minerals contained in the sand. In the present invention, magnetic force selection and magnetic force separation can be performed together.

That is, the magnetic force separation unit (60) is provided inside the outlet (12) of the specific gravity separation unit (50). The inside of the outlet portion 12 is mainly a place where heavy components gather. Heavy components are mainly useful minerals, and useful minerals are again classified as magnetic and non-magnetic. 2 and 3, when the magnet is provided on the side of the body 10 of the specific gravity separating unit 50, the magnetic body of the heavy water proceeding along the innose of the channel portion 13 acts as a magnetic force And is drawn into the innermost innose as indicated by the arrow in Fig. That is, the magnetic substance and the non-magnetic substance are separated from each other in the heavy water. It is preferable to additionally provide the partition member 25 as indicated by the dotted line 25 in FIG. 2 so that the magnetic body and the non-magnetic body can be separated and discharged separately.

The magnetic force separation unit (60) has a magnet (61) and a rotary shaft (62). In this embodiment, the magnet 61 is formed in a circular shape, and an electromagnet or a permanent magnet can be used. A rotating shaft 62 is coupled to the center of the magnet 61. The rotating shaft 62 is again driven by a rotating means such as a motor (not shown) to rotate the magnet 61.

As shown in FIG. 3, in this embodiment, the magnet 61 rotates clockwise to correspond to the traveling direction of the optical fluid. The magnet 61 stops rotating without stopping, and the magnetic bodies are attached to the side surface of the channel portion 13 by the magnetic force, and can stop without advancing. So that the magnets (61) are rotated so that the magnetic bodies can be discharged through the outlet (13).

The important thing is the strength of the magnet. The intensity of the magnet can be set differently depending on the kind of mineral to be separated. Magnetite is a ferromagnetic substance and is sensitive to weak magnetic force of 1,000 ~ 2,000G. In the case of the mesenite and magnetite, the magnets are attached to magnets at an intensity of 2,500 to 4,000G. The abbreviations epydot, hazy red and hematite can be attached at 5,000 ~ 7,000G. However, rutile, monazite, and zircon have very low magnetic susceptibility and can only be attached to magnets with an intensity of 8,000 to 10,000G. Zircon is a completely non-magnetic material and therefore does not adhere regardless of the strength of the magnet.

Therefore, the magnitude of the magnet should be determined according to the characteristics of the minerals contained in the sand to be separated. If you want to separate Zikkon and Monazite, you should use magnets with a strength of about 9,000G. However, if the sand is predominantly magnetite or ilmenite, you can use a magnet with a strength of about 3,500G.

As described above, in the present invention, the light sand component of the silica material and the heavy beneficial minerals are separated from each other by the specific gravity separation, and the heavy beneficial minerals can be separated into the magnetic body and the non-magnetic body again.

As a result, according to the present invention, the sand can be separated from the magnetic heavy mineral, the non-magnetic heavy mineral and the light mineral.

1 to 3 illustrate and illustrate that the magnet 61 is rotated on a vertical plane, the magnet may rotate on a horizontal plane as shown in FIG. Referring to Fig. 4, the magnet 68 lies like a millstone. 4, the rotating direction of the magnet 68 coincides with the traveling direction of the optical fluid, so that the optical fluid flows along the channel portion 13 and is discharged.

The scope of protection of the present invention is not limited to the description and the expression of the embodiments explicitly described in the foregoing. It is again to be understood that the present invention is not limited by the modifications or substitutions that are obvious to those skilled in the art.
