The application provides a preferred embodiment, the structure of the magnetic gathering medium is designed to be in a spiral spring shape, and the spiral spring-shaped magnetic gathering medium is formed. The spiral spring-shaped universal finger is of an equal-diameter spiral spring structure. Preferably, the cross-sectional shape of the wire of the coil spring-shaped magnetic recording medium may be in various forms, such as an oval shape, a circular shape (see fig. 7-1), a rectangular shape (see fig. 7-2), or a diamond shape (see fig. 7-3), etc. In the magnetic separation application, the magnetic lines of force are parallel to the axial direction of the spiral spring-shaped magnetic gathering medium, and the non-uniform magnetic fields of the circular, rectangular and rhombic corresponding separation spaces are respectively shown in fig. 8-1, fig. 8-2 and fig. 8-3. Therefore, in the magnetic separation application, the magnetic mineral particles can be adsorbed at the corresponding action gap position on each spiral coil of the spiral spring-shaped magnetic gathering medium.
The action principle of the spiral spring-shaped magnetic gathering medium is similar to that of the existing magnetic gathering rod medium, and the two media are different in expression form. The cross section of the existing magnetism gathering rod medium is parallel to the direction of a magnetic line of force (the magnetism gathering rod medium is axially vertical to the magnetic line of force) to obtain a non-uniform magnetic field, and the magnetism gathering rod medium is in a straight strip rod structure and correspondingly provided with a straight line cross section group which is arranged side by side along a straight line. The spiral spring-shaped magnetic gathering medium can be regarded as a spiral section group which is arranged in a spiral mode, and all sections of the spiral section group are parallel to the direction of magnetic lines of force in a same way (namely the spiral spring-shaped magnetic gathering medium is parallel to the direction of the magnetic lines of force in the axial direction) to obtain a non-uniform magnetic field.
As shown in fig. 9, the spiral spring-shaped magnetic focusing medium is cut along the axial direction (arbitrarily divided equally), each cut portion obtained independently corresponds to an existing magnetic focusing rod medium, and each spiral spring-shaped magnetic focusing medium corresponds to an existing group of multiple magnetic focusing rod media arranged in parallel (that is, the number of spiral turns of the spiral spring-shaped magnetic focusing medium corresponds to the number of magnetic focusing rod media arranged in parallel) in a macroscopic view. From this, embody in the installation, present need to every excellent medium both ends welded fastening installation, and the present case only need gather magnetic medium's both ends support the circle portion to each helical spring shape can, be equivalent to only need to gather two excellent mediums of tip of magnetic rod medium group and install, other excellent mediums of centre realize supporting each other in order through the spiral mode (need not one-by-one fixed mounting), and structural design is very novel unique, brings simple to operate, quick, with low costs advantage. The installation mode of the spiral spring-shaped magnetic gathering medium can be fixed installation or assembly, for example, the spiral spring-shaped magnetic gathering medium is fixedly installed on a medium box, or a mutual assembly structure is formed between the medium and the box, and the medium and the box can be simply assembled.
The sorting effect of the spiral spring-shaped magnetic gathering medium in magnetic separation application is greatly improved compared with that of the existing rod medium. Due to the limitation of materials, the traditional magnetism-gathering rod medium is designed to ensure the strength, and the cross section of the rod medium and the gap between adjacent rod media are designed with certain lower limit requirements, so that the magnetic field gradient and the filling rate are not high. The helical structure characteristic of the magnetic medium is gathered to this case helical spring shape through parameter such as reasonable adjustment wire rod cross-section, spring external diameter, compromises medium intensity and thin footpath optimal design, and helical spring shape gathers magnetic medium and can do each other (dislocation) next-door neighbour's setting (see fig. 11), brings the packing rate height, and the magnetic resistance is little, and magnetic field gradient improves, does benefit to magnetic separation effects such as fine particle level magnetism thing and promotion mineral recovery rate.
The spiral spring-shaped magnetic gathering medium can change the spring elastic coefficient of the spiral spring-shaped magnetic gathering medium by reasonably adjusting relevant parameters such as wire diameter, thread pitch (pitch) and medium outer diameter, thereby reasonably improving the structural strength of the spiral spring-shaped magnetic gathering medium, properly enhancing the suction resistance (the capability of resisting mutual attraction) between adjacent spiral coils, and changing the filling rate by reasonably changing the diameter and the gap of the spiral spring-shaped magnetic gathering medium, thereby changing and optimizing the balance between the capturing capability and the collecting amount. In the magnetic separation application, the spiral spring-shaped magnetic gathering media can well ensure stable structure under the condition of close-spacing (close proximity) arrangement, the problem that two adjacent spiral spring-shaped magnetic gathering media are staggered mutually can be well avoided, and the problem of magnetic short circuit is avoided.
The cross-sectional shape of the wire of the helical spring-shaped magnetic recording medium is, as shown in fig. 8-1, 8-2, and 8-3, the maximum length of the cross section corresponding to the axial direction and the radial direction of the helical spring-shaped magnetic recording medium is a and b, respectively. Preferably, the thread pitch of the spiral spring-shaped magnetic gathering medium is 0.5-1.5 times of a; the outer diameter of the spiral spring-shaped magnetic gathering medium is 3-10 times of b. Further, the ratio of a to b ranges from 1:1 to 2: 1. In a particularly preferred embodiment, when the cross-sectional shape of the wire of the helical spring-shaped magnetic medium is circular, a and b are both wire diameters, and the wire diameter is 0.2-2 mm. In one embodiment, as shown in fig. 10, the diameter d of the wire is 1 mm, and the pitch t of the helical spring-shaped magnetic medium is equal to the diameter d of the wire; the outer diameter D of the helical spring-shaped magnetic recording medium is 5 times the wire diameter D. When the cross section of the wire of the spiral spring-shaped magnetic gathering medium is rectangular, a and b are respectively the length and the width of the rectangle, the ratio of the a to the b is 2:1, wherein the value of the b is 0.2-2 mm. When the wire of the spiral spring-shaped magnetic gathering medium is in a diamond shape, a and b are respectively a rhombic diagonal line, and the equivalence of the diagonal lines is 0.2-2 mm.
Preferably, the spiral shape of the spiral spring-shaped magnetic medium can have various forms, such as the most common circular shape (e.g., the circular shapes in the embodiments shown in fig. 7-1, 7-2, and 7-3), and a polygonal shape, such as a square, a pentagon, a hexagon, an octagon, and so on.
The medium box 23 and the magnetic field unit 31 are installed in such a manner that the axial direction of the helical spring-shaped magnetic-concentrating medium is parallel to the direction of the magnetic lines of force, and the flowing direction of the mineral aggregate may be along the axial direction or the radial direction of the helical spring-shaped magnetic-concentrating medium (this embodiment), i.e., the mineral aggregate may pass through the helical spring-shaped magnetic-concentrating medium from the axial direction or the radial direction of the helical spring-shaped magnetic-concentrating medium. The structural feature of this case helical spring shape gathers magnetic medium makes it have the advantage that is difficult to block up in high gradient magnet separator uses, and especially mineral aggregate flow direction is for gathering the axial condition of magnetic medium along helical spring shape, because helical spring shape gathers magnetic medium inside has along the hollow channel of axial extension, and this hollow channel supplies the mineral aggregate to flow, avoids the effect clearance region that is used for adsorbing magnetic substance between each helicoidal, brings the magnetic separation effect that does not block up totally here.
