Description

Technical Field

[0001] This utility model relates to the field of magnetic mineral sorting technology, specifically a magnetic mineral sorting device. Background Technology

[0002] Magnetic mineral sorting is a technique that separates minerals based on their magnetic differences. The following is a basic overview of magnetic mineral sorting: Magnetic mineral sorting is based on the difference in mineral response in a magnetic field. By applying a magnetic field, it utilizes the magnetic difference between magnetic minerals and non-magnetic impurities for separation. During sorting, magnetic minerals are generally crushed into smaller particles to achieve finer separation. Then, magnetic sorting equipment is used for further sorting, including dry sorting. Typically, mineral particles are sprinkled onto a rotating drum. The drum contains magnetic zones, allowing non-magnetic impurities to fall from one side of the drum. Magnetic mineral particles are attracted to the magnetic zones within the drum and discharged from the non-magnetic zones as the drum rotates, thus achieving the sorting purpose.

[0003] Existing dry sorting equipment suffers from several drawbacks. Due to the limited size of the drum, the discharge points of concentrate and impurities are relatively close. When impurities are thrown out, they can easily enter the discharge point of concentrate, causing mixing between concentrate and impurities and reducing the sorting effect. Furthermore, when magnetic mineral particles are carried by the drum to the magnetic attraction area below the drum, the friction between the magnetic mineral particles and the drum decreases under the influence of gravity. The magnetic mineral particles may roll and stagnate at the bottom of the drum, thus reducing the sorting efficiency.

[0004] Therefore, those skilled in the art have provided a magnetic mineral sorting device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic mineral sorting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic mineral sorting device, comprising a frame, a first conveyor belt on the frame, the discharge end of the first conveyor belt being inclined downwards, a permanent magnet roller on the roller at the discharge end of the first conveyor belt, a receiving plate on the frame, a second conveyor belt on the frame, and fixed plates opposite each other on the frame, with a permanent magnet plate between the two fixed plates, the permanent magnet plate being parallel to the first conveyor belt and close to the permanent magnet roller.

[0007] Preferably, the receiving plate is inclined and is provided with guide plates.

[0008] Preferably, the conveyor belt is provided with multiple baffles, which are arranged at an angle.

[0009] Preferably, a flexible retaining ring 1 is provided on the first conveyor belt, and a flexible retaining ring 2 is provided on the second conveyor belt.

[0010] Preferably, the frame is provided with multiple support rods, each of the multiple support rods is provided with a base, the base is provided with a support spring, the top of the support spring is provided with a support seat, a feeding hopper is provided between the multiple support seats, the feeding hopper is provided with a discharge port, and a vibration motor is provided on the feeding hopper.

[0011] Preferably, the discharge port is a strip-shaped structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, a permanent magnet roller and a permanent magnet plate are installed. The permanent magnet roller is mounted on one of the rotating shafts of the conveyor belt, which is inclined and fixedly mounted on the frame. The permanent magnet roller can adsorb magnetic mineral particles on the conveyor belt, while non-magnetic mineral particles can fall from the end of the conveyor belt. The permanent magnet plate is fixedly mounted between two fixed plates, which are respectively mounted on the frame. The permanent magnet plate can adsorb magnetic mineral particles coming from the permanent magnet roller. It can cooperate with the permanent magnet roller to adsorb magnetic mineral particles, increase the distance between the falling positions of non-magnetic impurities and magnetic mineral particles on the conveyor belt, prevent the two from mixing when discharged, and improve the screening effect.

[0014] In this invention, by setting baffles, multiple baffles are equidistantly installed on the first conveyor belt, which can rotate with the first conveyor belt. When the magnetic mineral particles are conveyed to the bottom of the first conveyor belt by the permanent magnet roller and permanent magnet plate, the pressure of the magnetic mineral particles on the first conveyor belt is reduced under the action of gravity, and the friction between the magnetic mineral particles and the first conveyor belt is reduced. The magnetic mineral particles may roll on the first conveyor belt and stop moving. The baffles can push the magnetic mineral particles, ensuring that the magnetic mineral particles move with the first conveyor belt. When non-magnetic impurities fall from the first conveyor belt, the non-magnetic impurities can fall from the edge of the baffles, further moving the non-magnetic impurities away from the first conveyor belt. This further increases the distance between the falling positions of non-magnetic impurities and magnetic mineral particles on the first conveyor belt, further preventing the two from mixing when discharged, and further improving the screening effect.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6In this embodiment of the present invention, a magnetic mineral sorting device includes a frame 1, on which a first conveyor belt 2 is mounted. The discharge end of the first conveyor belt 2 is inclined downwards. A permanent magnet roller 3 is mounted on the roller at the discharge end of the first conveyor belt 2. A receiving plate 4 is mounted on the frame 1. A second conveyor belt 5 is also mounted on the frame 1. The frame 1 is a frame structure that can firmly support the sorting device. The first conveyor belt 2 and the second conveyor belt 5 are commercially available and are made of rubber. The first conveyor belt 2 is fixedly mounted on the frame 1. When non-magnetic impurities in the magnetic mineral particles fall on the first conveyor belt 2, the downwardly inclined first conveyor belt 2 can increase the angle between the non-magnetic impurities and the end of the first conveyor belt 2, allowing the non-magnetic impurities to fall away from the end of the first conveyor belt 2, preventing the non-magnetic impurities from adhering to the end of the first conveyor belt 2, and improving the screening effect. The permanent magnet roller 3 is fixedly mounted on the rotating shaft at the discharge end of the first conveyor belt 2. The permanent magnet roller 3 is commercially available. The permanent magnet roller 3 is uniformly installed inside, which makes the outer wall of the permanent magnet roller 3 magnetic. When the magnetic mineral particles are conveyed to the permanent magnet roller 3 by the first conveyor belt 2, the magnetic mineral particles can be attracted to the first conveyor belt 2 by the permanent magnet roller 3. The magnetic mineral particles can be transported from the top of the first conveyor belt 2 to the bottom of the first conveyor belt 2. Non-magnetic impurities are not attracted by the permanent magnet roller 3 and can fall from the end of the first conveyor belt 2, which can realize the screening of magnetic mineral particles and non-magnetic impurities. The receiving plate 4 is fixedly installed on the frame 1 and located below the first conveyor belt 2. It can catch the non-magnetic impurities falling from the first conveyor belt 2, which is convenient for the collection of non-magnetic impurities. The second conveyor belt 5 is fixedly installed on the frame 1 and located below the first conveyor belt 2. After the magnetic mineral particles leave the attraction range of the permanent magnet roller 3 and the permanent magnet plate 7, the second conveyor belt 5 can catch the magnetic mineral particles falling from the first conveyor belt 2, which can transport the magnetic mineral particles from the bottom of the frame 1 to one end of the frame 1, which is convenient for their collection.

[0024] In one embodiment, specifically, the frame 1 is provided with two fixed plates 6 facing each other, and a permanent magnet plate 7 is provided between the two fixed plates 6. The permanent magnet plate 7 is parallel to the conveyor belt 2 and is close to the permanent magnet roller 3. The fixed plates 6 are fixedly installed on the frame 1, and the permanent magnet plate 7 is fixedly installed between the two fixed plates 6 and close to the permanent magnet roller 3. When the magnetic mineral particles are attracted by the permanent magnet roller 3 and move on the conveyor belt 2, the permanent magnet plate 7 can continue to attract the magnetic mineral particles, enabling the magnetic mineral particles to be conveyed for a further distance on the conveyor belt 2. This increases the distance between the falling positions of non-magnetic impurities and magnetic mineral particles, preventing them from mixing during discharge and improving the screening effect. The permanent magnet plate 7 is parallel to the conveyor belt 2, ensuring that the magnetic mineral particles below the conveyor belt 2 are subjected to uniform adsorption force, preventing them from falling off the conveyor belt 2 within the magnetic attraction area of ​​the permanent magnet plate 7, and ensuring that the magnetic mineral particles only fall after moving to the end of the permanent magnet plate 7. This further prevents the magnetic mineral particles from mixing with non-magnetic impurities during discharge and further ensures the screening effect.

[0025] The receiving plate 4 is inclined and has guide plates 8 on it. The inclined receiving plate 4 can prevent non-magnetic impurities from accumulating on it and facilitate their collection. The guide plates 8 are fixedly installed at both ends of the receiving plate 4. When non-magnetic impurities fall up and down on the receiving plate 4, the guide plates 8 can gather the non-magnetic impurities and further facilitate their collection.

[0026] Based on the above embodiments, specifically, the conveyor belt 2 is provided with multiple baffles 9, which are inclined and fixedly installed at equal intervals on the conveyor belt 2. When the magnetic mineral particles are conveyed to the bottom of the conveyor belt 2 by the permanent magnet roller 3 and the permanent magnet plate 7, the pressure of the magnetic mineral particles on the conveyor belt 2 decreases under the action of gravity, and the friction between the magnetic mineral particles and the conveyor belt 2 decreases. The magnetic mineral particles may roll on the conveyor belt 2 and stop moving. At this time, the baffles 9 can push the magnetic mineral particles, ensuring that the magnetic mineral particles move with the conveyor belt 2. Furthermore, when non-magnetic impurities fall from the conveyor belt 2, the non-magnetic impurities can fall from the edge of the baffles 9, further moving the non-magnetic impurities away from the conveyor belt 2 as they fall. This further increases the distance between the falling positions of the non-magnetic impurities and the magnetic mineral particles on the conveyor belt 2, further preventing the mixing of the two when they are discharged, and further improving the screening effect.

[0027] Furthermore, flexible retaining rings 10 and 11 are respectively provided on conveyor belt 2. Flexible retaining rings 10 and 11 are respectively provided on conveyor belt 5. Flexible retaining rings 10 are fixedly installed on conveyor belt 2 and abut against both ends of baffle 9, which can prevent mineral particles from falling from both sides of conveyor belt 2. Flexible retaining rings 11 are fixedly installed on conveyor belt 5, which can prevent magnetic mineral particles from falling from conveyor belt 5 when conveyor belt 5 transports magnetic mineral particles.

[0028] In one embodiment, specifically, the frame 1 is provided with multiple support rods 12, each of the multiple support rods 12 is provided with a base 13, each base 13 is provided with a support spring 14, the top of each support spring 14 is provided with a support seat 15, a feed hopper 16 is provided between the multiple support seats 15, the feed hopper 16 is provided with a discharge port 17, and a vibration motor 18 is provided on the feed hopper 16. The multiple support rods 12 are relatively fixedly installed on the top of one end of the frame 1 and located above the conveyor belt 2. The bases 13 are respectively fixedly installed on the top of the multiple support rods 12, and the support springs 14 are respectively fixedly installed on the multiple bases 13. At the top of 3, support bases 15 are fixedly installed on the top of multiple support springs 14, and feed hopper 16 is fixedly installed between multiple support bases 15. Multiple support bases 15 can support feed hopper 16. Vibration motor 18 is fixedly installed at the bottom of feed hopper 16 and can drive feed hopper 16 to vibrate, which can prevent mineral particles in feed hopper 16 from accumulating. Feed inlet is opened at the bottom of feed hopper 16. Vibration motor 18 drives feed hopper 16 to vibrate, which can make mineral particles inside feed hopper 16 fall from discharge port 17 and fall onto conveyor belt 2, which is convenient for screening mineral particles.

[0029] Furthermore, the discharge port 17 is a strip-shaped arrangement, which allows mineral particles to fall evenly onto the conveyor belt 2, ensuring a uniform thickness of mineral particles at the top of the conveyor belt 2, improving the screening effect, and ensuring uniform adsorption force of the permanent magnet roller 3 and permanent magnet plate 7 on the magnetic mineral particles, further improving the screening effect.

[0030] When magnetic minerals need to be sorted, firstly, the magnetic mineral particles are poured into the feed hopper 16. Then, the vibrating motor 18, conveyor belt 2, and conveyor belt 5 are started. The vibrating motor 18 drives the feed hopper 16 to vibrate. As the feed hopper 16 vibrates, the magnetic mineral particles inside the feed hopper 16 are discharged from the outlet 17. As the conveyor belt 2 rotates, the mineral particles are evenly dispersed on the conveyor belt 2. Subsequently, under the conveying of the conveyor belt 2, the magnetic mineral particles are sent to the permanent magnet roller 3. Under the magnetic attraction of the permanent magnet roller 3, the magnetic mineral particles are attracted to the conveyor belt 2. At the same time, as the conveyor belt 2 rotates, non-magnetic mineral impurities fall from the end of the conveyor belt 2. Subsequently, the non-magnetic mineral impurities fall onto the receiving plate 4 and fall along the guide plate 8. During the descent, non-magnetic impurities are gathered by the guide plate 8 and then collected. Subsequently, as the conveyor belt 2 continues to rotate, magnetic mineral particles are sent to the area below the permanent magnet plate 7 by the permanent magnet roller 3. The permanent magnet plate 7 then continues to adsorb the magnetic particles onto the conveyor belt 2. During the adsorption of magnetic mineral particles by the permanent magnet roller 3 and the permanent magnet plate 7, the baffle 9 pushes the magnetic mineral particles to prevent them from rolling and stagnating on the conveyor belt 2. When the magnetic mineral particles leave the adsorption area of ​​the permanent magnet plate 7 with the conveyor belt 2, they fall onto the second conveyor belt 5. Under the action of the second conveyor belt 5, the magnetic mineral particles are transported to one end of the frame 1 and then collected.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
