[0002] Magnetic separator is one of the most widely used and versatile machines in the industry, mainly used to separate materials with magnetic differences. Magnetic separators are widely used in mining, wood, kiln, chemical, food and other industries. As for the mining industry, magnetic separators are suitable for wet or dry magnetic separation of materials such as manganese ore, magnetite, pyrrhotite, roasted ore, ilmenite, hematite, etc. with a particle size of less than 50mm. They are also used for iron removal of materials such as coal, non-metallic minerals, and building materials. During the operation of the magnetic separator, in order to ensure the accuracy and quality of magnetic separation, it is necessary to operate with a suitable feed rate. Therefore, when the feed rate is increased, the magnetic separation accuracy and quality can still be guaranteed, which can greatly improve the magnetic separation efficiency. Utility Model Content

[0003] The utility model provides a vertical belt magnetic separator which can ensure the precision and quality of magnetic separation under the condition of increasing feeding speed by means of two magnetic separations, thereby improving the magnetic separation efficiency.

[0004] To this end, the present application provides a vertical belt magnetic separator, and the technical solution adopted is as follows:

[0005] It includes a frame and a feeder, the feeder is located on the top of the frame, and a magnetic separation belt group 1 is horizontally laid below the feeder; the magnetic separation belt group 1 includes a conveying roller 1 and a magnetic separation roller 1 rotatably connected to the frame, and a conveying belt 1 is sleeved on the conveying roller 1 and the magnetic separation roller 1 for transmission by means of the rotation of the two, the conveying roller 1 is driven to rotate by a driving device 1, and a magnetic separation belt group 2 is horizontally laid below the magnetic separation belt group 1.

[0006] The transmission direction of the magnetic separation belt group 2 is opposite to that of the magnetic separation belt group 1, and it includes a conveying roller 2 and a magnetic separation roller 2 rotatably connected to the frame. The conveying roller 2 and the magnetic separation roller 2 are provided with a conveying belt 2 which is driven by the rotation of the two. The conveying roller 2 is driven to rotate by a driving device 2; a slag dropping channel is fixed below the magnetic separation roller 1, and the magnetic separation roller 2 extends into the interior of the slag dropping channel through the side wall of the slag dropping channel, and a discharge port is connected below the conveying roller 2.

[0007] A further technical solution is that the magnetic separation belt group 2 also includes an adjustment roller, and the number of the adjustment rollers is two, which are respectively located obliquely above the conveying roller 2 and the magnetic separation roller 2 and are arranged close to each other, and the adjustment roller located obliquely above the magnetic separation roller 2 is magnetic, and the conveyor belt 2 surrounds the adjustment roller.

[0008] A further technical solution is that a tensioning device is connected to both ends of the conveying roller 1, the conveying roller 1 has a central axis, the tensioning device includes a slider rotatably connected to the central axis, and a slide rail matching the slider, and the slide rail is arranged along the transmission direction of the magnetic separation belt group 1.

[0009] A screw rod arranged along its sliding direction is fixed on the slider, a fixing plate is fixed on the frame, the other end of the screw rod passes through the fixing plate, a nut matching its thread is sleeved on the screw, two nuts are respectively located on both sides of the fixing plate to lock the screw rod and the fixing plate; an adjustment hole is opened on the frame, the adjustment hole is a strip hole arranged along a transmission direction of the magnetic separation belt group, and the central axis passes through the adjustment hole and is connected to the slider.

[0015] 2. The second magnetic separation belt group is a double-layer design. The magnetically separated materials will first pass through the slope formed by the adjustment roller and then be brought into the discharge port by the second conveyor belt.

This avoids mutual contamination between materials and ensures the purity of the collected materials. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 5 As shown, a vertical belt magnetic separator includes a frame 100 and a feeder 101, wherein the feeder 101 is located on the top of the frame 100, and a magnetic separation belt group 1 is horizontally laid below the feeder 101; the magnetic separation belt group 1 includes a conveying roller 11 and a magnetic separation roller 12 rotatably connected to the frame 100, and a conveying belt 13 is sleeved on the conveying roller 11 and the magnetic separation roller 12 for transmission by rotation of the conveying roller 11 and the magnetic separation roller 12, and the conveying roller 11 is driven to rotate by a driving device 14, and a magnetic separation belt group 2 is horizontally laid below the magnetic separation belt group 1.

[0025] The transmission direction of the magnetic separation belt group 2 is opposite to that of the magnetic separation belt group 1, and includes a conveying roller 21 and a magnetic separation roller 22 rotatably connected to the frame 100. The conveying roller 21 and the magnetic separation roller 22 are sleeved with a conveying belt 23 that is driven by the rotation of the two. The conveying roller 21 is driven to rotate by a driving device 24; a slag dropping channel 102 is fixed below the magnetic separation roller 12, and the magnetic separation roller 22 extends into the interior of the slag dropping channel 102 through the side wall of the slag dropping channel 102, and a discharge port 103 is connected below the conveying roller 21.

[0026] When the magnetic separator is in use, mineral materials enter from the feeder 101 and are fed onto the magnetic separation belt group 1, which is driven by the conveyor belt 13. When passing through the magnetic separation roller 12, the magnetic particles are adsorbed, and the adsorbed magnetic particles continue to be transmitted with the conveyor belt 13 until the adsorption force of the magnetic separation roller 12 on them disappears and then they fall onto the magnetic separation belt group 2. The non-magnetic particles continue to run with the conveyor belt 13 to the downward turn and fall to the slag channel 102 below due to gravity, and gradually fall through the magnetic separation roller 22 to be adsorbed again, and the remaining magnetic particles in the slag are adsorbed onto the conveyor belt 23. In this way, the conveyor belt 23 sends all the magnetic particles separated twice to the discharge port 103 for collection.

[0027] By setting up magnetic separation belt group 1 and magnetic separation belt group 2, the material that has been magnetically separated by magnetic separation belt group 1 can be magnetically separated again by magnetic separation belt group 2 after entering the slag dropping channel 102, thereby meeting a faster pace of material feeding and ensuring a high degree of completion of magnetic separation, thereby improving the efficiency of magnetic separation.

[0028] like Figure 5 As shown, the magnetic separation belt group 2 also includes an adjustment roller 25. There are two adjustment rollers 25, which are respectively located obliquely above the conveying roller 21 and the magnetic separation roller 22 and are arranged close to each other. The adjustment roller 25 located obliquely above the magnetic separation roller 22 is magnetic, and the conveying belt 23 surrounds the adjustment roller 25.

[0029] Therefore, after the second magnetic separation, when the conveyor belt 23 drives the magnetic materials to move toward the discharge port 103, the conveyor belt 23 will form an upward slope due to the adjustment roller 25, and the magnetic separation roller 22 and the adjustment roller 25 on this side will work together to ensure that the magnetic materials will not fall off, and the non-magnetic materials that fall on the conveyor belt 23 after the first magnetic separation will fall along the slope to the slag channel 102. Similarly, the adjustment roller 25 on the other side will assist the conveyor roller 21 to form a downward slope along the transmission direction, so that the collected magnetic materials can quickly fall into the discharge port 103.

[0030] The second magnetic separation belt group is a double-layer design. The magnetically separated material will first pass through the slope formed by the adjustment roller 25 and then be brought into the discharge port 103 by the conveyor belt 23, ensuring that the material brought in is the part adsorbed by the magnetic separation roller 22 and the adjustment roller 25 on this side, rather than the part that falls on the conveyor belt 23 through the slag channel 102, thereby avoiding mutual contamination between materials and ensuring the purity of the collected part of the material.

[0031] like Figure 4 As shown, a tensioning device 15 is connected to both ends of the conveying roller 11, and the conveying roller 11 has a central axis 111. The tensioning device 15 includes a slider 151 rotatably connected to the central axis 111, and a slide rail 152 matching the slider 151, and the slide rail 152 is arranged along the transmission direction of the magnetic separation belt group.

[0032] A screw rod 153 arranged along its sliding direction is fixed on the slider 151, and a fixing plate 154 is fixed on the frame 100. The other end of the screw rod 153 passes through the fixing plate 154, and a nut 155 matching the thread thereof is sleeved on the screw rod 153. There are two nuts 155, which are respectively located on both sides of the fixing plate 154 to lock the screw rod 153 and the fixing plate 154; an adjustment hole 156 is opened on the frame 100, and the adjustment hole 156 is a strip hole arranged along a transmission direction of the magnetic separation belt group, and the central axis 111 passes through the adjustment hole 156 and is connected to the slider 151.

[0033] The tensioning device 15 can adjust the position of the central axis 111, i.e., the conveying roller 11, thereby changing the distance between the conveying roller 11 and the magnetic separation roller 12 to adjust the tension of the conveying belt 13. The adjustment method is to loosen the nut 155, adjust the distance of the screw 153 extending out of the fixing plate 154, thereby changing the position of the central axis 111 in the adjustment hole 156, and tighten the nut 155 after adjusting to a suitable position.

[0034] like Figure 2 As shown, baffles 3 are fixed at intervals on conveyor belt 1 13 and conveyor belt 2 23, and the baffles 3 are arranged perpendicular to the surfaces of conveyor belt 1 13 and conveyor belt 2 23. Baffles 3 can prevent the mineral material from diffusing in the opposite direction of transmission due to inertia, thereby maintaining the efficiency of conveying the mineral material. In addition, a vibration device is fixed at the bottom of the frame 100, and the vibration device includes a high-frequency vibrator 41 and a vibrator bracket 42 located at the bottom of the high-frequency vibrator 41. Thereby, non-magnetic materials can be quickly removed by vibration. In addition, a flushing device 5 is fixed at the discharge port 103. Rapid demagnetization is achieved by the flushing device 5 to ensure rapid collection of magnetic materials.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
