Description

Technical Field

[0001] This application relates to the technical field of sorting and recycling magnetic materials using magnetic force, and in particular to a magnetic separator with parallel-distributed multi-drums for purifying magnetic materials. Background Technology

[0002] Currently, magnetic separators play a crucial role as the core equipment for separating magnetic and non-magnetic substances. Single-drum magnetic separators for purifying magnetic materials are widely used in small and medium-sized mineral processing plants and material pretreatment stages due to their relatively simple structure and low cost. This equipment uses the magnetic field generated by the magnetic drum to attract magnetic materials, and then uses the rotation of the drum to separate magnetic and non-magnetic substances.

[0003] From the perspective of magnetic separation effect, its magnetic field distribution is uneven, making it difficult to take into account materials with different magnetic strengths. This makes it difficult to balance the concentrate grade and recovery rate. The single-drum magnetic separator has limited processing capacity and cannot meet the needs of large-scale production. The low separation efficiency limits the improvement of production efficiency, and its recovery effect on fine-grained and weakly magnetic materials is poor.

[0004] Regarding the aforementioned technologies, the applicant believes that they have the drawback of poor recovery effect on fine-particle and weakly magnetic materials. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a magnetic separator for purifying magnetic materials using multiple parallel-distributed drums.

[0006] This application provides a magnetic separator for purifying magnetic materials using multiple parallel-distributed drums, employing the following technical solution:

[0007] A magnetic separator for purifying magnetic materials using multiple parallel-distributed drums includes a feeding mechanism, a material conveying mechanism, multiple sets of drum mechanisms, a collecting mechanism, a system, and a frame. The feeding mechanism is installed in front of the drum mechanisms and on the material conveying mechanism, and is detachably connected to the frame. The multiple sets of drum mechanisms are arranged in parallel along the discharge direction, and are detachably connected to the frame. The material conveying mechanism is located at the bottom of the drum mechanisms and is detachably connected to the frame. The collecting mechanism is located at the boundary between the magnetic and non-magnetic areas between the material conveying mechanism and the drum mechanisms, and is detachably connected to the frame. The drive system is fixedly connected to the frame and provides power to the feeding mechanism, the material conveying mechanism, the multiple sets of drum mechanisms, and the collecting mechanism.

[0008] By adopting the above technical solution, the material is fed into the feeding mechanism and discharged. The material reaches the material conveying mechanism and is conveyed to multiple sets of roller mechanisms. The multiple sets of roller mechanisms are arranged in parallel along the discharge direction to form a multi-stage magnetic separation process. Magnetic materials can undergo multiple adsorption and separation under the action of the magnetic field of different rollers. Even substances with weak magnetic properties and fine particle size can be effectively extracted, which greatly improves the concentrate grade and recovery rate. The parallel setting of multiple rollers significantly increases the magnetic separation area and the separation path length, and can process more materials per unit time. The collection mechanism collects the magnetic materials of the roller mechanism and sends them to the collection mechanism through the conveying mechanism.

[0009] Multiple sets of drum mechanisms are arranged in parallel along the discharge direction to form a multi-stage magnetic separation process. Magnetic materials can undergo multiple adsorption and separation under the action of magnetic fields in different drums. Even substances with weak magnetic properties and fine particle size can be effectively extracted, which greatly improves the grade and recovery rate of concentrate. The parallel setting of multiple drums significantly increases the magnetic separation area and separation path length, and can process more materials per unit time.

[0010] Preferably, the feeding mechanism includes a feeding hopper, a first discharging mechanism, and a vibrating motor. The feeding hopper is detachably connected to the frame. The first intermittent feeding mechanism is installed on one side of the bottom of the feeding hopper. The first discharging mechanism is detachably connected to the feeding hopper. The vibrating motor is installed on the other side of the feeding hopper and is detachably connected to the feeding hopper.

[0011] By adopting the above technical solution, the first discharge mechanism is installed on one side of the bottom of the feeding hopper, which can realize the intermittent supply of materials. The vibration motor is installed on the other side of the feeding hopper. When it is working, it will cause the feeding hopper to vibrate. This vibration can effectively prevent the materials from agglomerating or bridging in the feeding hopper and promote the smooth falling of the materials.

[0012] Preferably, the material conveying mechanism includes a conveyor belt, multiple drive rollers, connecting rods, and rubber guide strips. The multiple drive rollers are connected by the connecting rods and arranged sequentially along the discharge direction. The conveyor belt is mounted on the multiple drive rollers, and the rubber guide strips are mounted on both sides of the conveyor belt and are fixedly connected to the conveyor belt.

[0013] By adopting the above technical solution, multiple drive rollers are arranged sequentially and rotatably connected along the discharge direction through connecting rods. This structure provides stable and smooth support for the conveyor belt. The rubber guide strips installed on both sides of the conveyor belt are fixedly connected to the conveyor belt. During the operation of the conveyor belt, the rubber guide strips can prevent materials from slipping off the sides of the conveyor belt.

[0014] Preferably, the roller mechanism includes a main roller, a bearing mechanism, a pneumatic spring, a slider, and a linear guide rail. The main roller is rotatably connected to the bearing mechanism, the bearing mechanism is detachably connected to the slider, the slider is slidably connected to the linear guide rail, one side of the pneumatic spring is detachably connected to the frame, the other side of the pneumatic spring is connected to the slider, and the linear guide rail is detachably connected to the frame.

[0015] By adopting the above technical solution, the main drum is connected to the slider through a bearing mechanism, and the slider can slide on the linear guide rail. This allows the main drum to make fine adjustments to its position according to the actual situation during operation. When encountering uneven material or other external interference, the main drum can slide along the linear guide rail and adaptively adjust its position through the buffering and adjustment effect of the pneumatic spring.

[0016] Preferably, the main roller includes a main shaft, a roller housing, and an adjustable rotating magnetic block. The main shaft is connected to the adjustable rotating magnetic block, the roller housing is installed outside the adjustable rotating magnetic block, and the roller housing is detachably connected to the main shaft.

[0017] By adopting the above technical solution, the adjustable rotating magnetic block is connected to the main shaft. The angle, position or arrangement of the adjustable rotating magnetic block can be directly adjusted according to the characteristics of the material, such as the strength of the magnetic field and the particle size. This changes the magnetic field strength and distribution pattern on the surface of the main drum, greatly improving the targeting and efficiency of magnetic separation.

[0018] Preferably, the collecting mechanism includes a scraper, a V-shaped feeding trough, a conveying mechanism, and a collecting mechanism. The scraper is detachably connected to the frame, with one side of the scraper installed on one side of the non-magnetic area of ​​the main roller. The V-shaped feeding trough is connected to the other side of the scraper and is inclinedly installed on the conveying mechanism. The conveying mechanism is detachably connected to the frame and is located at the bottom of the V-shaped feeding trough. The collecting mechanism is installed at the rear of the conveying mechanism and above the conveyor belt in the material conveying mechanism, and is detachably connected to the frame.

[0019] By adopting the above technical solution, the scraper is detachably connected to the frame and installed on the non-magnetic side of the main drum. When the main drum rotates, the magnetic material is adsorbed on the surface of the main drum. As the main drum rotates to the non-magnetic area, the scraper can accurately scrape the magnetic material off the surface of the main drum. The V-shaped feeding trough is connected to the other side of the scraper, and the scraped magnetic material will fall directly into the V-shaped feeding trough. The V-shaped design can guide the material to flow to the conveying mechanism in a concentrated manner, avoiding the material from scattering. The collecting mechanism is installed at the rear of the conveying mechanism and on one side of the feeding mechanism, which can collect the magnetic material conveyed by the conveying mechanism.

[0020] Preferably, the conveying mechanism includes a conveyor belt, a drive roller, a driven roller, and a baffle. The plurality of drive rollers are arranged sequentially along the discharge direction via connecting rods. The drive roller and the driven roller are mounted on the drive roller and the driven roller. The baffle is mounted on both sides of the conveyor belt and is detachably connected to the frame.

[0021] By adopting the above technical solution, the structure of the active roller and driven roller combined with the conveyor belt forms a stable transmission system. The active roller provides power to drive the conveyor belt to operate, while the driven roller plays a supporting and guiding role, ensuring the smooth operation of the conveyor belt. This allows magnetic materials to be quickly and continuously transported from the V-shaped feeding trough to the collecting mechanism, reducing and improving the overall production efficiency of the magnetic separator. The baffles installed on both sides of the conveyor belt can effectively prevent materials from slipping off the sides during the conveying process.

[0022] Preferably, the material collection mechanism includes a material discharge box and a second intermittent discharge mechanism, the second discharge mechanism being installed on one side of the bottom of the material discharge box and detachably connected to the material discharge box.

[0023] By adopting the above technical solution, the second discharge mechanism controls the material discharge from the discharge port of the discharge box, so that the material that has already undergone magnetic separation can be magnetically separated again. The second magnetic separation can further separate the magnetic particles that remain after the first magnetic separation.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] Multiple sets of drum mechanisms are arranged in parallel along the discharge direction to form a multi-stage magnetic separation process. Magnetic materials can undergo multiple adsorption and separation under the action of magnetic fields in different drums. Even substances with weak magnetic properties and fine particle size can be effectively extracted, which greatly improves the grade and recovery rate of concentrate. The parallel setting of multiple drums significantly increases the magnetic separation area and separation path length, and can process more materials per unit time.

[0026] The second discharge mechanism controls the material discharge from the discharge box, allowing the material that has already undergone magnetic separation to undergo a second magnetic separation. This second magnetic separation can further separate the magnetic particles that remain after the first magnetic separation. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0037] This application discloses a magnetic separator for purifying magnetic materials using multiple parallel-distributed drums. (Refer to...) Figure 1 The system includes a feeding mechanism 1, a material conveying mechanism 2, multiple sets of roller mechanisms 3, a collecting mechanism 4, a drive system 5, and a frame 6. The feeding mechanism 1 is installed in front of the roller mechanism 3 and on the material conveying mechanism 2, and is detachably connected to the frame 6. The multiple sets of roller mechanisms 3 are arranged in parallel along the discharge direction. The material conveying mechanism 2 is located at the bottom of the roller mechanism 3 and is detachably connected to the frame 6, forming a multi-stage magnetic separation process. Even substances with weak magnetic properties and fine particle size can be effectively extracted. The collecting mechanism 4 is located at the junction of the magnetic and non-magnetic areas between the material conveying mechanism 2 and the roller mechanism 3. It is used to collect the materials that have been magnetically screened by the magnetic separator. The collecting mechanism 4 is detachably connected to the frame 6. The drive system 5 is fixedly connected to the frame 6 and provides power to the feeding mechanism 1, the material conveying mechanism 2, the multiple sets of roller mechanisms 3, and the collecting mechanism 4.

[0038] Reference Figure 1 and Figure 2The feeding mechanism 1 is installed in front of the roller mechanism 3 and on the material conveying mechanism 2. The feeding mechanism 1 is detachably connected to the frame 6. The first discharge mechanism 12 is installed on one side of the bottom of the feeding hopper 11. The vibration motor 13 is installed on the other side of the feeding hopper 11. The vibration of the vibration motor 13 prevents the material from getting blocked in the feeding hopper 11 and promotes the smooth falling of the material.

[0039] Reference Figure 1 and Figure 3 It has two sets of material conveying mechanisms 2, one set located below the first discharge mechanism 12 and the other set located below the roller mechanism 3. The two sets of material conveying mechanisms 2 are connected in a V-shape. A material pusher is set at the bend of the V-shape. The material pusher mechanism includes a hydraulic cylinder and a pusher plate. The hydraulic cylinder is connected to the pusher plate to push the material from one set of material conveying mechanisms 2 to the other set of material conveying mechanisms 2. The material conveying mechanism 2 includes a conveyor belt 21, multiple drive rollers 22, connecting rods 23 and rubber guide strips 24. The multiple drive rollers 22 are arranged sequentially and rotatably connected along the discharge direction through the connecting rods 23. The conveyor belt 21 is installed on the multiple drive rollers 22, and the multiple drive rollers 22 provide support for the conveyor belt 21. The rubber guide strips 24 are installed on both sides of the conveyor belt 21 to prevent the material from slipping off the sides of the conveyor belt 21.

[0040] Reference Figure 4 and Figure 5 The roller mechanism 3 includes a main roller 31, a bearing mechanism 32, a pneumatic spring 33, a slider 34, and a direct-drive guide rail 35. The main roller 31 includes a main shaft 311, a roller shell 312, and an adjustable rotating magnetic block 313. The main shaft 311 is connected to the adjustable rotating magnetic block 313. The roller shell 312 is installed outside the adjustable rotating magnetic block 313. The adjustable rotating magnetic block 313 is rotatably connected to the main shaft 311. The adjustable rotating magnetic block 313 is semi-cylindrical. The angle of the adjustable rotating magnetic block 313 can be directly adjusted according to the characteristics of the material, such as the strength of the magnetic field and the particle size, so as to change the magnetic field strength and distribution. The main roller 31 is connected to the slider 34 through the bearing mechanism 32. The slider 34 can slide on the direct-drive guide rail 35, so that the main roller 31 can slide along the direct-drive guide rail 35. Through the buffering and adjustment effect of the pneumatic spring 33, it adaptively adjusts its own position.

[0041] Reference Figure 6 and Figure 7 as well as Figure 8The collecting mechanism 4 includes a scraper 41, a V-shaped feeding trough 42, a conveying mechanism 43, and a collecting mechanism 44. The scraper 41 is installed on the non-magnetic side of the main roller 31. When the main roller 31 rotates, magnetic materials are attracted to the surface of the main roller 31. The scraper 41 can accurately scrape the magnetic materials off the surface of the main roller 31, and the magnetic materials will fall directly into the V-shaped feeding trough 42. The V-shaped feeding trough 42 is installed at an angle on the conveying mechanism 43. The conveying mechanism 43 includes a conveyor belt 431, a driving roller 432, a driven roller 433, and a baffle 434. The magnetic materials scraped off by the scraper 41 are sent to the V-shaped feeding trough 42. The conveying mechanism 43 has multiple drive rollers 22 arranged sequentially along the discharge direction via connecting rods 23. The drive roller 432 provides power to drive the conveyor belt 431 to operate, while the driven roller 433 provides support and guidance, allowing the magnetic material to be conveyed from the V-shaped feeding trough 42 to the collecting mechanism 44. The collecting mechanism 44 includes a discharge box 441 and a second discharge mechanism 442. At this time, the first discharge mechanism 12 and the second discharge mechanism 442 are manually controlled. When the first discharge mechanism 12 stops feeding, the second discharge mechanism 442 starts feeding, and when the first discharge mechanism 12 starts feeding, the second discharge mechanism 442 stops feeding.

[0042] The working principle of a parallel-distributed multi-drum magnetic separator for purifying magnetic materials in this application is as follows: After the material is put into the feeding hopper 11 in the feeding mechanism 1, the first discharging mechanism 12 opens to discharge the material. The vibration of the vibration motor 13 prevents the material from clogging. The material reaches the conveyor belt 21 of the material conveying mechanism 2. The drive roller 22 rotates to move the material on the conveyor belt 21 to the drum mechanism 3. The rubber guide strip 24 is installed on the conveyor belt 21 to prevent the material from deviating and spilling. The main drum 31 in the drum mechanism 3 includes an adjustable rotating magnetic block 313. The angle and position of the adjustable rotating magnetic block 313 can be directly adjusted according to the strength of the magnetic field and the size of the particle, thereby changing the magnetic field strength. The main drum 31 and the bearing mechanism 32 The slider 34 is slidably connected to the linear guide rail 35. One side of the slider 34 is connected to the bearing mechanism 32, and the other side is connected to the air spring 33. This allows the main roller 31 to adaptively adjust its position through the buffering and adjustment effect of the air spring 33. The scraper 41 collects the magnetic material of the roller mechanism 3 and feeds it into the conveying mechanism 43 through the V-shaped feeding trough 42. Then, it is fed into the collecting mechanism 44 through the conveying mechanism 43. When the second discharge mechanism 442 opens the feeding box 441 to start feeding, the first discharge mechanism 12 closes the feeding hopper 11 so that the feeding mechanism 1 stops feeding. Conversely, when the feeding mechanism 1 starts feeding, the second discharge mechanism 442 closes the feeding box 441 to stop feeding.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
