Description

Technical Field

[0001] This utility model belongs to the field of magnetic separator technology, and in particular relates to a drum-type dry magnetic separator. Background Technology

[0002] Magnetic separation technology is a method of separating minerals based on differences in their magnetic properties, and it is widely used in mining, metallurgy, chemical industry, environmental protection, and other fields. Magnetic separators, as key equipment in the magnetic separation process, use magnetic fields to separate different magnetic minerals, thereby achieving the purpose of purifying and recovering useful minerals.

[0003] Traditional magnetic separators typically have fixed magnetic components, making it impossible to flexibly adjust their magnetic strength according to the magnetic characteristics of the ore being separated. When dealing with ores of varying magnetic strengths, such as strongly magnetic iron ore and weakly magnetic manganese ore, the equipment struggles to achieve ideal separation results, necessitating the replacement of equipment with different magnetic specifications or the entire magnetic component. This not only increases equipment investment costs but also reduces production efficiency. Furthermore, existing equipment often features integrated magnetic components; if some areas experience magnetic attenuation or damage, the entire magnetic assembly must be replaced, leading to high maintenance costs and prolonged equipment downtime, impacting continuous production.

[0004] To address these issues, we provide a drum-type dry magnetic separator. Utility Model Content

[0005] The purpose of this invention is to provide a drum-type dry magnetic separator. By adding or removing magnetic strips, the device can directly change the magnetic strength of the mounting frame, adapting to minerals with different magnetic characteristics and improving the equipment's adaptability to various minerals. When the magnetic strips become weak or damaged due to long-term use, they can be disassembled and replaced individually without replacing the entire mounting frame, reducing maintenance costs and downtime. This solves the problem that existing magnetic components are mostly fixed structures, and their magnetic strength cannot be flexibly adjusted according to the magnetic characteristics of the minerals to be separated.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a drum-type dry magnetic separator, including a machine body shell, and a through hole is opened on the rear side of the machine body shell;

[0007] A bracket is fixed to the rear side of the outer shell of the machine body, a support rod is fixed to one side of the bracket, a bearing is fixed to one end of the support rod, and a transmission ring is fixed to the inner ring of the bearing;

[0008] A first baffle is fixed to one end of the transmission ring, and a magnetic separator is fixed to one side of the first baffle.

[0009] A positioning rod is fixed to one side of the bracket, and a positioning plate is fixed to one end of the positioning rod. The positioning rod passes through the transmission ring.

[0010] A fixing frame is fixed to one side of the positioning plate, and several mounting strips are fixed to the outside of the fixing frame;

[0011] A magnetic strip is slidably connected inside the mounting strip, and a fixing plate is fixed to one side of the magnetic strip;

[0012] Both the fixing plate and the fixing frame have a first threaded hole on their surfaces.

[0013] The present invention is further configured such that: a first motor is fixed on one side of the bracket, and a rotating block is fixed on the output shaft of the first motor;

[0014] Several first transmission blocks are fixed on the outside of the rotating block.

[0015] The present invention is further configured such that: a plurality of second transmission blocks are fixed on the outer side of the transmission ring, and a transmission belt is sleeved between the first transmission block and the second transmission block.

[0016] The present invention is further configured such that: a first mounting ring is fixed on the side of the magnetic separator away from the first baffle, and a second mounting ring is fixed on one side of the first mounting ring by bolts;

[0017] A second baffle is fixed to one side of the second mounting ring;

[0018] A limit rod is fixed on one side of the second baffle.

[0019] The present invention is further configured such that: a partition is fixed at the bottom of the outer shell of the machine body, and a collection box is placed on both sides of the partition.

[0020] The present invention is further configured such that: a protective plate is fixed on one side of the outer shell of the machine body, and positioning blocks are fixed on both sides of the protective plate and the outer shell of the machine body;

[0021] The positioning block has a second threaded hole on its surface;

[0022] A limit ring is fixed on the side of the protective plate away from the outer shell of the machine body, and the limit rod rotates within the limit ring.

[0023] The present invention is further configured such that: a feed inlet is fixed to the top of the outer shell of the machine body, a second motor is fixed to the outside of the feed inlet, and the output shaft of the second motor passes through the outer shell of the machine body;

[0024] The output shaft of the second motor is fixed with a transmission rod, and several stirring blades are fixed on the outside of the transmission rod.

[0025] This utility model has the following beneficial effects:

[0026] 1. This utility model utilizes the magnetic strips. By increasing or decreasing the number of magnetic strips on the mounting strip, the magnetic strength of the fixing frame can be directly changed, making it suitable for minerals with different magnetic characteristics and improving the equipment's adaptability to various minerals. When the magnetic strips experience magnetic attenuation or damage due to long-term use, they can be disassembled and replaced individually without replacing the entire fixing frame, thus reducing maintenance costs and minimizing equipment downtime.

[0027] 2. This utility model utilizes the action of stirring blades, which rotate under the drive of a second motor. This stirring blades can agitate and disperse the ore poured in from the feed inlet, preventing the ore from falling in large quantities at once due to clumping or accumulation. The ore falls evenly and slowly onto the outside of the magnetic separator. Furthermore, by controlling the falling speed and distribution of the ore, it can prevent insufficient adsorption or disordered sorting caused by the surface of the magnetic separator being subjected to too much ore at once. This ensures that non-magnetic ore can fall smoothly into the corresponding collection box, while magnetic ore can be stably adsorbed on the magnetic separator to complete subsequent separation. This ensures that the magnetic separation process proceeds in an orderly manner and improves sorting accuracy. Attached Figure Description

Specific Implementation Example 1

[0045] Please see Figure 1-10This utility model is a drum-type dry magnetic separator, including a machine body shell 1, with a through hole 2 on the rear side of the machine body shell 1; a bracket 3 is fixed to the rear side of the machine body shell 1, a support rod 4 is fixed to one side of the bracket 3, a bearing 5 is fixed to one end of the support rod 4, and a transmission ring 6 is fixed to the inner ring of the bearing 5; a first baffle 7 is fixed to one end of the transmission ring 6, and a magnetic separator drum 8 is fixed to one side of the first baffle 7; a positioning rod 9 is fixed to one side of the bracket 3, a positioning plate 10 is fixed to one end of the positioning rod 9, and the positioning rod 9 passes through the transmission ring 6; a fixing frame 11 is fixed to one side of the positioning plate 10, and several mounting strips 12 are fixed to the outside of the fixing frame 11; a magnetic strip 13 is slidably connected inside the mounting strip 12, and a fixing plate 14 is fixed to one side of the magnetic strip 13; both the fixing plate 14 and the fixing frame 11 have first threaded holes 15 on their surfaces.

[0046] Specifically, a first motor 16 is fixed on one side of the bracket 3, and a rotating block 17 is fixed on the output shaft of the first motor 16; several first transmission blocks 18 are fixed on the outside of the rotating block 17; several second transmission blocks 19 are fixed on the outside of the transmission ring 6, and a transmission belt 20 is sleeved between the first transmission blocks 18 and the second transmission blocks 19.

[0047] Furthermore, a first mounting ring 21 is fixed to the side of the magnetic separator 8 away from the first baffle 7, and a second mounting ring 22 is fixed to the side of the first mounting ring 21 by bolts; a second baffle 23 is fixed to the side of the second mounting ring 22; and a limit rod 24 is fixed to the side of the second baffle 23.

[0048] The operation process of this embodiment is as follows: The first motor 16 is started, and its output shaft drives the rotating block 17 and the outer first transmission block 18 to rotate. The transmission belt 20 drives the transmission ring 6 to rotate, and the transmission ring 6 drives the magnetic separator 8 to rotate synchronously through the first baffle 7. At this time, the bearing 5 and the limiting rod 24 rotate within the support rod 4 and the limiting ring 30 respectively, ensuring the stable rotation of the magnetic separator 8. During the magnetic separation process, non-magnetic minerals, due to lack of adsorption, fall directly from the surface of the magnetic separator 8 under gravity and fall into the collection box 26 near the fixed frame 11. Magnetic minerals are adsorbed onto the surface of the magnetic separator 8 by the magnetic strips 13 on the fixed frame 11 and continue to rotate with the magnetic separator 8. When rotating to the side without the fixed frame 11, i.e., the area where the magnetism disappears, the adsorption force is lost, and the minerals fall into the collection box 26 on the other side under gravity, completing the sorting. If it is necessary to adjust the magnetism of the equipment according to the magnetic characteristics of the minerals, it can be done by disassembling the equipment. Remove the bolts on the positioning block 28, remove the protective plate 27, and then remove the bolts connecting the second mounting ring 22 and the first mounting ring 21. Remove the second baffle 23 and the limiting rod 24 to expose one side opening of the magnetic separator 8. If it is necessary to enhance the magnetism, add magnetic strips 13 and fix them to the first threaded hole 15 on the fixing plate 14 with bolts. If it is necessary to weaken the magnetism, remove some of the magnetic strips 13. After adjustment, reinstall the second baffle 23 and the protective plate 27 to ensure that all components are reset and fixed. This device can directly change the magnetic strength of the fixing frame 11 by adding or removing the number of magnetic strips 13 on the mounting strip 12, which can adapt to minerals with different magnetic characteristics and improve the equipment's adaptability to various minerals. When the magnetic strips 13 are weakened or damaged due to long-term use, they can be disassembled and replaced separately without replacing the entire fixing frame 11, reducing maintenance costs and equipment downtime. Specific Implementation Example 2

[0050] Please see Figure 3-10 Based on the first specific embodiment, a partition 25 is fixed at the bottom of the outer shell 1, and a collection box 26 is placed on both sides of the partition 25.

[0051] Specifically, a protective plate 27 is fixed on one side of the outer shell 1, and positioning blocks 28 are fixed on both sides of the protective plate 27 and the outer shell 1; a second threaded hole 29 is opened on the surface of the positioning block 28; a limit ring 30 is fixed on the side of the protective plate 27 away from the outer shell 1, and the limit rod 24 rotates within the limit ring 30.

[0052] Furthermore, a feed inlet 31 is fixed to the top of the outer casing 1, and a second motor 32 is fixed to the outside of the feed inlet 31. The output shaft of the second motor 32 passes through the outer casing 1. A transmission rod 33 is fixed to the output shaft of the second motor 32, and several stirring blades 34 are fixed to the outside of the transmission rod 33.

[0053] The operation process of this embodiment is as follows: When the device is in use, the second motor 32 is started, and its output shaft drives the transmission rod 33 and the stirring blade 34 to rotate. The ore to be magnetically separated is poured in from the feed inlet 31. After being stirred by the stirring blade 34, the ore is evenly dispersed and guided through the feed inlet 31 to fall onto the outer surface of the magnetic separator 8. By setting the stirring blade 34, which rotates under the drive of the second motor 32, the device can stir and disperse the ore poured in from the feed inlet 31, avoiding the ore from falling in large quantities at once due to agglomeration or accumulation. This allows the ore to fall onto the outer surface of the magnetic separator 8 at a uniform and slow speed. Furthermore, by controlling the falling speed and distribution of the ore, the device can prevent insufficient adsorption or disordered sorting due to excessive ore on the surface of the magnetic separator 8. This ensures that non-magnetic ore can fall smoothly into the corresponding collection box, and magnetic ore can be stably adsorbed on the magnetic separator 8 to complete subsequent separation, thereby ensuring that the magnetic separation process proceeds in an orderly manner and improving sorting accuracy.
