Description

Technical Field

[0001] The present application relates to the technical field of recycling waste materials, and in particular to a suspended magnetic separator. Background Art

[0002] Magnetic separators are often used to magnetically separate raw materials during garbage sorting and mineral processing. Among them, suspended magnetic separators are widely used in scenarios where magnetic separation is required because of their advantages such as easy installation and easy height adjustment. In existing suspended magnetic separators, a NdFeB permanent magnet with strong magnetic force is installed inside to facilitate the adsorption of iron debris in the raw materials. However, the iron parts such as the rollers of existing equipment are also magnetic due to the long-term influence of high-intensity magnetic fields, which causes the rollers to carry magnetism, resulting in the tiny iron filings on the sorting belt being constantly adsorbed on the sorting belt, affecting the sorting effect. Therefore, a suspended magnetic separator is required, which uses a plastic roller on the blanking side to prevent the magnetization of the roller from affecting the blanking of iron debris. At the same time, an air blowing device is provided on the blanking side to regularly clean the iron powder attached to the sorting belt, and a structure that is easy to replace the roller is provided on the bracket to reduce the difficulty of replacing the roller.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0023] like Figures 1 to 3 As shown, an embodiment of the utility model provides a suspended magnetic separator, comprising: a conveyor belt 1, which is installed on the ground and is used to transport raw materials to be sorted; a main bracket 2, a lifting ring 3 is provided on the upper part of the main bracket 2, and the main bracket 2 is suspended above one end of the conveyor belt 1 by a lifting rope or a connecting rod, a support plate 7 is provided in the middle part of the main bracket 2, a first driven roller 4 and a second driven roller 5 are provided on both sides of the main bracket 2, and the first driven roller 4 and the second driven roller 5 are connected to the main bracket 2 through a rotating shaft, and an active roller 6 is provided on the upper part of the main bracket 2, and the active roller 6 is connected to the main bracket 2 through a first sub-bracket 8; a sorting belt 9, the inner wall of the sorting belt 9 is tightly attached to the outer sides of the first driven roller 4, the second driven roller 5 and the active roller 6; wherein the second driven roller 5 is made of plastic, and an air nozzle 10 is provided on one side of the second driven roller 5.

[0024] When using a suspended magnetic separator to sort iron debris, the raw materials to be sorted are poured onto the conveyor belt 1, and then the raw materials are driven by the conveyor belt 1 to move toward the main support 2. When the raw materials pass under the NdFeB permanent magnet 11, the iron debris is affected by the magnetic force and moves upward and closely adheres to the outside of the sorting belt 9. The sorting belt 9 moves from the first driven roller 4 to the second driven roller 5 under the drive of the active roller 6. When the sorting belt 9 moves, it will drive the iron debris to move together. After the sorting belt 9 moves a distance, the iron debris moves from the lower part of the NdFeB permanent magnet 11 to the lower part of the support block 12. Since the support block 12 has no magnetic force, the iron debris falls freely under the action of gravity to the collecting hopper at the lower part of the main support 2, and the raw materials after magnetic separation fall into the collecting hopper at one end of the conveyor belt 1, thereby achieving the purpose of magnetic separation.

[0025] As the sorting belt 9 moves from the first driven roller 4 to the second driven roller 5, iron debris mainly falls near the second driven roller 5, that is, the blanking side of the magnetic separator is near the second driven roller 5. In order to prevent the second driven roller 5 from being magnetized and affecting the falling of fine iron filings, the present application adopts a second driven roller 5 made of plastic material on the blanking side to reduce the influence of magnetization on the sorting of iron debris, and an air nozzle 10 is provided on one side of the second driven roller 5. When the sorting belt 9 deflects upward on the second driven roller 5, the air nozzle 10 can be used to regularly spray air to this position, and the fine iron filings attached to the sorting belt 9 can be blown off by high-speed airflow to avoid long-term attachment of fine iron filings to the sorting belt 9.

[0026] Specifically, Figure 2 As shown, a NdFeB permanent magnet 11 and a support block 12 are provided at the lower part of the support plate 7, the upper end surfaces of the NdFeB permanent magnet 11 and the support block 12 are connected to the support plate 7, and the lower end surfaces of the NdFeB permanent magnet 11 and the support block 12 are fitted with the inner side of the sorting belt 9. The NdFeB permanent magnet 11 is installed on the side close to the first driven roller 4, and the NdFeB permanent magnet 11 generates magnetic force to absorb iron debris. The support block 12 has no magnetic force and only supports the sorting belt 9. After the iron debris moves from the bottom of the NdFeB permanent magnet 11 to the bottom of the support block 12, it falls under the action of gravity due to the reduction of magnetic force. The material of the support block 12 is polytetrafluoroethylene, which has good wear resistance and low friction coefficient, and can ensure that it has a sufficient service life under long-term friction of the sorting belt 9.

[0027] In a preferred embodiment, a second sub-bracket 13 is provided on the main bracket 2, a drive motor 14 is installed on the upper part of the second sub-bracket 13, and a plastic pad 15 is provided between the drive motor 14 and the second sub-bracket 13. The drive motor 14 is installed through the second sub-bracket 13, which can be away from the neodymium iron boron permanent magnet 11, thereby reducing the influence of the magnetic force on the drive motor 14. The plastic pad 15 can play a role in shock absorption and reducing magnetic force transmission, thereby reducing the influence of the magnetic force on the drive motor 14.

[0028] Specifically, the driving motor 14 is connected to the active roller 6 through a synchronous belt or a chain. When the driving motor 14 rotates, the sorting belt 9 moves from the first driven roller 4 to the second driven roller 5. The driving motor 14 drives the active roller 6, thereby driving the sorting belt 9 to move. The sorting belt 9 drives the iron debris away from the neodymium iron boron permanent magnet 11, so that it falls into the hopper under the action of gravity.

[0029] In a specific embodiment, Figure 3 As shown, a mounting groove 16 is provided on the main bracket 2, and the rotating shaft on the second driven roller 5 is installed in the mounting groove 16, and a clamping block 17 is provided in the mounting groove 16, and the clamping block 17 is slidably connected with the mounting groove 16, and one side of the clamping block 17 is pressed tightly against one side of the rotating shaft of the second driven roller 5, and the other side of the clamping block 17 is connected to the main bracket 2 by a bolt. The second driven roller 5 is made of plastic, and the rotating shaft of the second driven roller 5 is made of metal. The wear resistance of the plastic material is poor, and the second driven roller 5 needs to be replaced regularly. When replacing, the clamping block 17 can slide freely in the mounting groove 16 after loosening the bolt. After removing the old second driven roller 5 and placing a new second driven roller 5 in the mounting groove 16, the clamping block 17 is inserted, and then the bolt is tightened. The middle part of the bolt is connected to the main bracket 2 through a nut welded on one side of the main bracket 2, and one end of the bolt is pressed against the clamping block 17, so that the clamping block 17 clamps the rotating shaft of the second driven roller 5 to keep the second driven roller 5 stable.

[0030] In a preferred embodiment, there are multiple air nozzles 10, which are arranged at intervals along the width direction of the sorting belt 9, the air outlet ends of the air nozzles 10 face the sorting belt 9, and the air inlet ends of the air nozzles 10 are connected in parallel to the high-pressure air source through air valves. When the sorting belt 9 deflects upward on the second driven roller 5, the air can be periodically sprayed at this position through the air nozzles 10, and the fine iron filings attached to the sorting belt 9 are blown off by the high-speed airflow to prevent the fine iron filings from being attached to the sorting belt 9 for a long time.

[0031] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
