Description

Technical Field

[0001] The invention relates to an assembly technology of a magnetic ring assembly of a high-magnetic field magnetic separator, in particular to an assembly device and an assembly method of a magnetic ring assembly of a high-magnetic field magnetic separator. Background Art

[0002] The basic working principle of the magnetic separator is to use the magnetic difference of minerals to separate them in the magnetic field of the magnetic separator. When mineral particles with different magnetic properties pass through the magnetic field of the magnetic separator, the mineral particles with stronger magnetic properties and the mineral particles with weaker magnetic properties are subjected to different magnetic forces, resulting in different movement trajectories, thereby selecting different minerals.

[0003] Strong magnetic field separators can generate high-intensity magnetic fields, and are mainly used for the sorting of weak magnetic minerals, non-metallic and tailings recovery, etc. As one of the permanent magnet components used to generate high-intensity magnetic fields in strong magnetic field separators, magnetic ring assemblies usually include metal rings and several pieces of fan-shaped NdFeB magnets with the same angles. Several pieces of fan-shaped NdFeB magnets with the same angles are bonded to the surface of the metal ring, and are spliced ​​in sequence to form a complete circular ring magnet with the same inner and outer diameters as the metal ring. The bonding surfaces of all fan-shaped NdFeB magnets have the same polarity. Strong magnetic field separators form permanent magnets by combining multiple magnetic ring assemblies of different polarities in a certain order and inserting them into the shaft body, generating a strong magnetic field to achieve the purpose of sorting. In order to make the strong magnetic field have a high uniformity, ensure the sorting effect, and be able to be smoothly inserted into the shaft body, there are high requirements for the uniformity of the arrangement of the several fan-shaped NdFeB magnets in the magnetic ring assembly.

[0004] There are two existing ways to assemble the magnetic ring assembly of a high-field magnetic separator. The first way is to manually bond them first and then magnetize the entire assembly, that is, first bond the fan-shaped NdFeB magnets to the metal ring manually, and then magnetize the entire assembly. The second way is to magnetize them first and then bond them manually, that is, first magnetize each fan-shaped NdFeB magnet separately, and then manually bond them to the metal ring.

[0005] In the first method mentioned above, during manual bonding, since the fan-shaped NdFeB magnets have no magnetism, the fan-shaped NdFeB magnets will not affect each other, and the bonding efficiency is high, which can ensure that the fan-shaped NdFeB magnets have a high arrangement uniformity. However, since the diameter of the magnetic ring assembly of the strong magnetic field magnetic separator is usually measured in meters, the magnetizing coil needs to be very large in size to achieve overall magnetization. The manufacturing cost and driving energy consumption of the large-sized magnetizing coil are very high. Therefore, the magnetization cost is extremely high, resulting in a high overall assembly cost. The second method mentioned above does not require a large-sized magnetizing coil, and the overall assembly cost is greatly reduced compared to the first method. However, since the fan-shaped NdFeB magnets have strong magnetism after magnetization, manual assembly may easily cause the fan-shaped NdFeB magnets to attract and collide with each other or cause the fan-shaped NdFeB magnets to flip due to magnetic pole repulsion. The repulsion between the fan-shaped NdFeB magnets may cause the fan-shaped NdFeB magnets to deflect and be unable to correctly locate the center of the circle, resulting in low bonding efficiency and difficulty in ensuring that the fan-shaped NdFeB magnets have a high arrangement uniformity. Summary of the invention

[0010] Compared with the prior art, the advantage of the assembly device of the magnetic ring assembly of the high magnetic field magnetic separator of the present invention is that the assembly device of the magnetic ring assembly of the high magnetic field magnetic separator is constructed by a fixture reference base, a magnetic steel spacing fixture and a positioning anti-flip fixture, the fan-shaped groove on the fixture reference base realizes the limitation of the metal ring, and the cooperation of the magnetic steel spacing fixture and the fixture reference base can bond a plurality of fan-shaped NdFeB magnets evenly spaced along a circle to the metal ring, and the inner arc surfaces of the plurality of fan-shaped NdFeB magnets are aligned with the inner circumferential surface of the metal ring, and there is a gap between any two adjacent fan-shaped NdFeB magnets that can just accommodate a fan-shaped NdFeB magnet to be embedded, and the gap is formed by the magnetic steel spacing fixture in the metal ring. After bonding a number of fan-shaped NdFeB magnets evenly spaced along a circle to the metal ring, the positioning anti-flip fixture cooperates with the fixture reference base to align its positioning cavity with the gap between two adjacent fan-shaped NdFeB magnets.

Even if the fan-shaped NdFeB magnet has strong magnetism, it will not produce mutual There is no repulsion effect. When the fan-shaped NdFeB magnet is installed by using the positioning anti-flipping fixture, due to the limitation of the positioning cavity, the fan-shaped NdFeB magnet in the positioning cavity will not be deflected due to the repulsion of the two adjacent fan-shaped NdFeB magnets, but will only float in the positioning cavity. At this time, by pressing down the fan-shaped NdFeB magnet in the positioning cavity, it can be accurately installed in the corresponding gap. Therefore, the present invention can magnetize the fan-shaped NdFeB magnet first and then install it.

DETAILED DESCRIPTION

[0032] The invention discloses an assembly device for a magnetic ring assembly of a high-magnetic field magnetic separator. The assembly device for a magnetic ring assembly of a high-magnetic field magnetic separator of the invention is further described in detail below in conjunction with the accompanying drawings.

[0033] Embodiment 1: An assembly device for a magnetic ring assembly of a high magnetic field magnetic separator, comprising a fixture reference base 1, a magnetic steel spacing fixture and a positioning anti-flip fixture; Figure 1 As shown, the fixture reference base 1 is a fan-shaped sheet structure, and a fan-shaped groove 2 is provided on its upper surface, which is concave downward and runs through from left to right; the fan-shaped groove 2 is coaxial with the fixture reference base 1, and its inner diameter is equal to the inner diameter of the metal ring 4, and its outer diameter is equal to the outer diameter of the metal ring 4. The groove depth is less than the thickness of the metal ring 4. When the metal ring 4 is embedded in the fan-shaped groove 2, the metal ring 4 can rotate along the fan-shaped groove 2; the magnetic steel spacing fixture is used to cooperate with the fixture reference base 1 when the metal ring 4 is embedded in the fan-shaped groove 2, so as to form two positioning areas 3 spaced apart from each other on the left and right, and each positioning area 3 is used to position a fan-shaped NdFeB magnet 5, so that when a fan-shaped NdFeB magnet 5 is bonded to the metal ring 4 under positioning, Its inner arc surface is aligned with the inner circumferential surface of the metal ring 4 (that is, located on the same circumferential surface), and the outer arc surface is aligned with the outer circumferential surface of the metal ring 4 (that is, located on the same circumferential surface). The spacing area between the two positioning areas 3 can just accommodate a fan-shaped NdFeB magnet 5 for embedding; the positioning anti-turnover fixture is provided with a positioning cavity 13 that matches the shape of a fan-shaped NdFeB magnet 5, and a fan-shaped NdFeB magnet 5 can translate up and down in the positioning cavity 13. The positioning anti-turnover fixture is used to cooperate with the fixture reference base 1, so that a fan-shaped NdFeB magnet 5 is pressed downward through the positioning cavity 13 until it is bonded to the metal ring 4, and the metal ring 4 can rotate along the fan-shaped groove 2 with the fan-shaped NdFeB magnet 5 bonded thereto.

[0034] In this embodiment, the fan-shaped groove 2 on the fixture reference base 1 realizes the limitation of the metal ring 4. The cooperation between the magnetic steel spacing fixture and the fixture reference base 1 can bond a plurality of fan-shaped NdFeB magnets 5 evenly spaced along a circle to the metal ring 4, and the inner arc surfaces of the plurality of fan-shaped NdFeB magnets 5 are aligned with the inner circumferential surface of the metal ring 4. There is a gap between any two adjacent fan-shaped NdFeB magnets 5 that can just accommodate a fan-shaped NdFeB magnet 5 to be embedded. After bonding a plurality of fan-shaped NdFeB magnets 5 evenly spaced along a circle to the metal ring 4 through the magnetic steel spacing fixture, The positioning anti-flipping fixture cooperates with the fixture reference base 1 so that its positioning cavity 13 is aligned with the gap between two adjacent fan-shaped NdFeB magnets 5. At this time, a fan-shaped NdFeB magnet 5 can be pressed downward into the gap through the positioning cavity 13 and bonded to the metal ring 4. After a fan-shaped NdFeB magnet 5 is bonded and solidified, the metal ring 4 and the fan-shaped NdFeB magnet 5 bonded and fixed thereon can be rotated so that the positioning cavity 13 on the positioning anti-flipping fixture is aligned with the gap between two adjacent fan-shaped NdFeB magnets 5 that have not yet been installed. After that, a fan-shaped NdFeB magnet 5 is pressed downward into the gap through the positioning cavity 13 and bonded to the metal ring 4. The cycle is repeated in sequence, and the fan-shaped NdFeB magnet 5 can be installed in the gaps between all two adjacent fan-shaped NdFeB magnets 5, so that the fan-shaped NdFeB magnets 5 bonded to the metal ring 4 are sequentially spliced ​​to form a complete annular magnet with the same inner diameter and outer diameter as the metal ring 4. At this time, a strong magnetic field magnetic separator magnetic ring assembly is obtained. When the fan-shaped NdFeB magnet 5 is installed by the magnetic steel spacing fixture, due to the presence of the positioning area 3, the fan-shaped NdFeB magnet 5 can be realized. It is precisely positioned and installed with the metal ring 4, and a gap is reserved that fully matches the size of the fan-shaped NdFeB magnet 5. Even if the fan-shaped NdFeB magnet 5 has strong magnetism, there will be no repulsion between each other. When the fan-shaped NdFeB magnet 5 is installed using a positioning anti-flip fixture, due to the limitation of the positioning cavity 13, the fan-shaped NdFeB magnet 5 in the positioning cavity 13 will not be deflected due to the repulsion between the two adjacent fan-shaped NdFeB magnets 5, but will only float in the positioning cavity 13. At this time, by pressing down on the fan-shaped NdFeB magnet 5 in the positioning cavity 13, it can be accurately installed in the corresponding gap.

[0035] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that: in this embodiment, Figure 2 and Figure 3As shown, the magnetic steel spacing fixture includes an arc strip 6 and a fan-shaped plate 7 with the same external dimensions as a fan-shaped NdFeB magnet 5. The thickness of the arc strip 6 is greater than that of the fan-shaped plate 7.

[0047] In summary, the assembly device and assembly method of the magnetic ring assembly of the high magnetic field magnetic separator of the present invention are provided by setting a fixture reference base 1, a magnetic steel spacing fixture and a positioning anti-flipping fixture. The fan-shaped groove 2 on the fixture reference base 1 realizes the limitation of the metal ring 4. The cooperation between the magnetic steel spacing fixture and the fixture reference base 1 can bond a plurality of fan-shaped NdFeB magnets 5 evenly spaced along a circle on the metal ring 4, and the inner arc surfaces of the plurality of fan-shaped NdFeB magnets 5 are aligned with the inner circumferential surface of the metal ring 4. There is a gap between any two adjacent fan-shaped NdFeB magnets 5 that can just accommodate a fan-shaped NdFeB magnet 5 to be embedded. When the fan-shaped NdFeB magnet 5 is installed by the magnetic steel spacing fixture, due to the presence of the positioning area 3, the fan-shaped NdFeB magnet 5 can be realized. The boron magnet 5 and the metal ring 4 are precisely positioned and installed, and a gap that fully matches the size of the fan-shaped NdFeB magnet 5 is reserved. Even if the fan-shaped NdFeB magnet 5 has strong magnetism, there will be no repulsion between each other. The positioning anti-flip fixture cooperates with the fixture reference base 1 to align its positioning cavity 13 with the gap between two adjacent fan-shaped NdFeB magnets 5 up and down. When the fan-shaped NdFeB magnet 5 is installed using the positioning anti-flip fixture, due to the limitation of the positioning cavity 13, the fan-shaped NdFeB magnet 5 in the positioning cavity 13 will not be deflected due to the repulsion of the two adjacent fan-shaped NdFeB magnets 5, but will only float in the positioning cavity 13. At this time, by pressing down on the fan-shaped NdFeB magnet 5 in the positioning cavity 13, it can be accurately installed at the corresponding gap. Therefore, the present invention can magnetize the fan-shaped NdFeB magnet 5 before installing it, which has a lower assembly cost. It can also overcome the mutual influence of the magnetized fan-shaped NdFeB magnet 5 during the bonding process, so that the bonding efficiency of the fan-shaped NdFeB magnet 5 is higher, and the fan-shaped NdFeB magnet 5 can be ensured to have a higher arrangement uniformity. It can generate greater benefits in the assembly of the magnetic ring assembly of the strong magnetic field magnetic separator, and has a broad application and promotion prospect.
