[0002] After being crushed, ground and processed step by step, the ore can be used in metal mining, metallurgical industry, chemical industry, construction industry and other engineering fields. Ore dressing is the most important link in the entire mineral production process. Commonly used magnetite dressing methods include gravity separation, flotation and magnetic separation. Among them, magnetic separation is a kind of ore dressing method that uses the difference in the magnetic properties of magnetite to separate it in the magnetic field of a magnetic separator.

[0003] Since mineral particles with different magnetic properties are subjected to different magnetic forces, they produce different movement trajectories, thereby separating the mineral particles into two or more separate mineral processing products according to their different magnetic properties. When traditional magnetic separators are used to separate mineral particles, it is not easy to control the feeding speed of the magnetic separators, resulting in low separation accuracy. In addition, traditional magnetic separators cannot control the amount of feeding, causing the equipment to be easily blocked by mineral particles, affecting the normal operation of the equipment.

The top of the bottom plate 1 is fixedly connected with the tailings collecting box 2 for collecting tailings, the top of the bottom plate 1 is fixedly connected with the weak iron ore collecting box 3 for collecting weak iron ore, the top of the bottom plate 1 is fixedly connected with the concentrate collecting box 4 for collecting concentrate, the weak iron ore collecting box 3 is fitted with the concentrate collecting box 4 and the tailings collecting box 2, the top of the bottom plate 1 is fixedly connected with the first leg 5, the top of the bottom plate 1 is fixedly connected with the second leg 51, the feeding frame 6 is fixedly connected between the first leg 5 and the second leg 51, the first leg 5 is provided with a beneficiation mechanism 7 for sorting ore, and the shaking mechanism 8 for accelerating the discharge speed is provided on the feeding frame 6.

[0045] The ore dressing mechanism 7 includes a motor 71, a first rotating shaft 72, a bevel gear 73, a third leg 74, a second rotating shaft 75, a rotating ring 76, a guide ring 77, a bevel gear ring 78, a magnet block 79 and a gear block 711. The motor 71 for providing power to the device is fixedly installed on the first leg 5. One end of the output shaft of the motor 71 is fixedly connected to the first rotating shaft 72. One end of the first rotating shaft 72 is vertically fixedly connected to the bevel gear 73. The third leg 74 is symmetrically fixed to the top of the bottom plate 1. The weak iron ore collection box 3 is located between the two third legs 74. A second rotating shaft 75 is rotatably connected between the two third legs 74, a rotating ring 76 is fixedly connected to the second rotating shaft 75, a guide ring 77 is connected to the outside of the rotating ring 76, the guide ring 77 is annular, a bevel gear ring 78 is fixedly connected to the second rotating shaft 75, the bevel gear ring 78 is meshed with the bevel gear 73, a magnet block 79 for adsorbing ore is fixedly connected to the third leg 74, the magnet block 79 is in contact with the rotating ring 76, and ten pairs of tooth blocks 711 are fixedly connected to the outside of the rotating ring 76 in an annular distributed manner, and the tooth block 711 adopts a double bevel structure.

[0046] The shaking mechanism 8 includes a first fixed frame 81, a feeding plate 82, a first return spring 83, a second fixed frame 84 and a protrusion 85. The first fixed frame 81 is fixedly connected to the feeding frame 6. The first fixed frame 81 is slidably connected with a feeding plate 82 for guiding the ore. The feeding plate 82 is U-shaped. The feeding plate 82 is in contact with the feeding frame 6. The feeding plate 82 is in contact with the guide ring 77.

The second fixed frame 84 is L-shaped. A protrusion 85 is connected to the first rotating shaft 72. The protrusion 85 is elliptical and in contact with the second fixed frame 84.

[0047] The ore particles to be sorted are poured into the unloading frame 6 through other unloading equipment, and the motor 71 is manually controlled to reverse. The motor 71 will drive the first rotating shaft 72 and the device thereon to reverse through the output shaft, so that the bevel gear 73 drives the bevel gear ring 78 and the device thereon to reverse, and the ore particles to be sorted in the unloading frame 6 will fall onto the rotating ring 76 through the unloading plate 82. Since the tailings are almost non-magnetic, the tailings fall directly into the tailings collection box 2. Since both the weak iron ore and the concentrate are magnetic, under the action of the magnet block 79, the weak iron ore and the concentrate are adsorbed on the rotating ring 76. Then, since the magnet block 79 is located above the weak iron ore collection box 3 and is thinner, and the magnetism of the weak iron ore is weaker than that of the concentrate, the weak iron ore falls into the weak iron ore collection box 3, and the concentrate can continue to be adsorbed on the rotating ring 76. Then, the concentrate will fall into the concentrate collection box 4, so as to achieve the purpose of automatically sorting the concentrate, weak iron ore and tailings.

[0048] During the reversal of the first rotating shaft 72 and the device thereon, the protrusion 85 will intermittently squeeze the second fixing frame 84 and the device thereon, so that the unloading plate 82 and the device thereon reset and shake, which is convenient for unloading. The above operation can be repeated to continuously select ore, and then the motor 71 is manually controlled to be turned off.

[0049] Example 2

[0050] On the basis of Example 1, Figure 6-12As shown, it also includes an adjusting mechanism 9, which is used to control the discharge speed according to the mass of the selected concentrate. The adjusting mechanism 9 is arranged on the concentrate collecting box 4, and the adjusting mechanism 9 includes a fixed block 91, a first sliding frame 92, a second return spring 93, a rotating frame 94, a torsion spring 95, a flat gear 96, a third fixed frame 97, a second sliding frame 98, a third return spring 99, a fixed rod 911, a first sliding plate 912, a fixed bar 913, a second sliding plate 914, a fourth return spring 915, a first rack 916, a fifth return spring 917 and a second rack The outer wall of the concentrate collecting box 4 is symmetrically fixed with a fixed block 91, and a first sliding frame 92 is slidably connected to the fixed block 91. A second reset spring 93 for driving the first sliding frame 92 to reset is connected between the first sliding frame 92 and the fixed block 91. A rotating frame 94 for receiving the concentrate is rotatably connected between the two first sliding frames 92. A torsion spring 95 for driving the rotating frame 94 to reset is connected between the rotating frame 94 and the first sliding frame 92. A flat gear 96 is symmetrically connected to the rotating frame 94. The top of the bottom plate 1 is symmetrically connected to a third fixed frame 97, a second sliding frame 98 is slidably connected to the third fixed frame 97, a third reset spring 99 for driving the second sliding frame 98 to reset is connected between the second sliding frame 98 and the third fixed frame 97, a fixed rod 911 is fixedly connected to the second sliding frame 98, and the fixed rod 911 is in the shape of a round rod, a first sliding plate 912 is slidably connected to the inside of the concentrate collecting box 4, and a fixed strip 913 is symmetrically connected to the first sliding plate 912, a second sliding plate 914 is slidably connected to the unloading frame 6, and the second sliding plate 914 is connected to the two fixed strips 913, and the second sliding plate A fourth reset spring 915 is connected between 914 and the blanking frame 6 for driving the second sliding plate 914 to reset; a first rack 916 is slidably connected to the blanking frame 6 for clamping the second sliding plate 914; the first rack 916 has a tooth-like structure on the side away from the blanking frame 6; a fifth reset spring 917 is connected between the first rack 916 and the blanking frame 6 for driving the first rack 916 to reset; a second rack 918 is slidably connected to the second sliding frame 98; the second rack 918 is located above the flat gear 96, and the second rack 918 is meshed with the flat gear 96.

[0051] The concentrate will first fall onto the rotating frame 94. When the material is dropped through the unloading plate 82 at a normal speed, after a certain amount of concentrate has accumulated on the rotating frame 94, two of the tooth blocks 711 located at the lower right side of the rotating ring 76 will push the fixed rod 911 and the device on it to move in the direction away from the third leg 74, and the third return spring 99 will be stretched accordingly, and the second rack 918 will drive the flat gear 96 and the device on it to rotate, and the torsion spring 95 will be compressed accordingly, so that the concentrate on the rotating frame 94 falls into the concentrate collecting box 4, and then the two of the tooth blocks 711 located at the lower right side of the rotating ring 76 will separate from the fixed rod 911, and the fixed rod 911 and the device on it will be reset in reverse one after another. When the material is dropped through the unloading plate 82 at a too fast speed, too much concentrate will accumulate on the rotating frame 94, causing the rotating frame 94 and the device on it to move downward under the action of gravity and push the first sliding plate 912 and the device on it to move downward, and the fourth return spring The positioning spring 915 will be stretched and the second return spring 93 will be compressed, so that the discharge port of the discharge frame 6 will be reduced, so that the number of ore particles to be sorted falling onto the discharge plate 82 is less, thereby controlling the discharge speed of the discharge plate 82. Through the cooperation of the first rack 916 and the fifth return spring 917, the first rack 916 can clamp the second sliding plate 914 to prevent it from resetting. When the discharge speed of the discharge plate 82 returns to normal, the second return spring 93 will reset and drive the rotating frame 94 and the device thereon to reset. The first rack 916 is manually pulled away from the rotating ring 76, and the fifth return spring 917 will be compressed, so that the first rack 916 no longer clamps the second sliding plate 914. The fourth return spring 915 will reset and drive the second sliding plate 914 and the device thereon to reset. The above operation can achieve the purpose of controlling the discharge speed according to the quality of the selected concentrate.

The fourth sliding plate 111 is symmetrically connected with a special-shaped frame 113, which is Z-shaped and connected to the third sliding plate 101.

[0055] During the rotation of the rotating ring 76 and the device thereon, two of the tooth blocks 711 located on the upper left of the rotating ring 76 will push the third sliding plate 101 and the device thereon to move toward the direction close to the blanking frame 6, and the sixth return spring 102 will be compressed accordingly, so that the third sliding plate 101 blocks the blanking plate 82, and at the same time the special-shaped frame 113 and the device thereon will also move, and the seventh return spring 112 will be compressed accordingly, so that the fourth sliding plate 111 will open, and the ore particles to be sorted in the blanking frame 6 will fall onto the blanking plate 82, and then the two tooth blocks 711 located on the upper left of the rotating ring 76 will move with the The third sliding plate 101 is separated, and the sixth reset spring 102 will reset accordingly and drive the third sliding plate 101 and the device thereon to reset, so that the third sliding plate 101 is opened. At this time, a certain amount of mineral particles are accumulated on the unloading plate 82, and the mineral particles on the unloading plate 82 fall onto the rotating ring 76. When the third sliding plate 101 and the device thereon are reset, the seventh reset spring 112 will reset and drive the fourth sliding plate 111 to reset, so that the fourth sliding plate 111 is closed, so that the mineral particles inside the unloading frame 6 will no longer fall out, thereby achieving the purpose of controlling the discharge speed of the equipment to prevent the equipment from being blocked.

The scraper 122 is slidably connected to the guide ring 77, and the scraper 122 is in contact with the rotating ring 76.

[0058] When the second fixing frame 84 and the device thereon reciprocate up and down, the connecting frame 121 and the device thereon also reciprocate up and down, so that the scraper 122 scrapes off the small particles of ore that may be adhered to the rotating ring 76 .
