[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Figure 1-Figure 7 As shown, the present invention provides a technical solution: a high gradient magnetic separator, comprising a magnetic separator body 15, a slurry inlet 3 is arranged on the magnetic separator body 15, a tailings bucket discharge port 4 and a small tailings bucket discharge port 5 are arranged at the bottom of the magnetic separator body 15, the tailings bucket discharge port 4 is arranged on the side of the small tailings bucket discharge port 5, and a concentrate trough discharge port 2 is arranged on the side of the magnetic separator body 15; A connecting seat is provided on both sides of the magnetic separator body 15, and a connecting pipe 16 is provided on the connecting seat. Fasteners 17 are clamped and connected at both ends of the connecting pipe 16. A buckle 18 is sleeved on the outer side of the fastener 17, and a handle 19 is provided on the outer side of the buckle 18. A positioning ring 20 is provided on the top of the connecting seat, and a positioning hole 21 is opened on the top of the positioning ring 20. A positioning pin 22 is connected to the inner side of the positioning hole 21, and the positioning pin 22 is crimped to the outer side of the single handle 19.

[0022] In this embodiment, after mining, the raw ore often contains multiple components, including both magnetic minerals and non-magnetic minerals. The core function of the magnetic separator body 15 is to accurately distinguish these mixed minerals. For the beneficiation of iron ore, the iron minerals therein have certain magnetism. The magnetic separator body 15 can select the iron minerals from a large number of gangue minerals, improve the grade of the iron ore, and make it meet the requirements of subsequent industrial processing such as smelting. In the preliminary treatment of some rare metal mines, such as the raw ore involved in the extraction process of rare earth permanent magnetic materials such as neodymium iron boron, the magnetic separator body 15 can effectively separate the rare earth mineral components with weak magnetism, which helps the subsequent refining and purification links. The magnetic minerals are adsorbed on the surface of the cylinder through the magnetic field to form a concentrate. The primary function of the concentrate trough discharge port 2 is to provide a discharge channel for these concentrates, so that the magnetic minerals after magnetic separation and enrichment can smoothly leave the magnetic separator and enter the subsequent further selection, dehydration, smelting, etc. The discharge speed and flow rate of the concentrate trough discharge port 2 need to match the processing capacity of the magnetic separator and the subsequent process flow to ensure the continuity and efficiency of the entire beneficiation process. The main function of the slurry inlet 3 is to provide the slurry material to be selected for the magnetic separator body 15. After the mined ore is processed in the early stage such as crushing and grinding, it is prepared into a slurry form and transported to the inside of the magnetic separator body 15 through the slurry inlet 3, so that the magnetic separator body 15 can separate the magnetic minerals therein. By setting a flow control device at the slurry inlet 3, such as a regulating valve, the slurry flow rate and speed entering the magnetic separator can be accurately controlled. Appropriate feed flow rate and speed are crucial to the magnetic separation effect, which can ensure that the slurry is evenly distributed in the magnetic separator, so that the magnetic minerals have enough time and opportunity to interact with the magnetic field, and improve the efficiency and accuracy of magnetic separation. The main function of the tailings bucket discharge port 4 is to discharge tailings such as non-magnetic minerals and minerals with weak magnetism that are not magnetically adsorbed during the magnetic separation process from the magnetic separator body 15. After magnetic separation, the minerals that cannot be adsorbed into the concentrate will fall into the tailings bucket and be discharged through the tailings bucket discharge port 4, so that the tailings and magnetic minerals are separated and the magnetic separation process is completed. In some complex magnetic separation processes or magnetic separation processes for special minerals, the small tailings bucket discharge port 5 can be used as a supplement to the tailings bucket discharge port 4 to discharge a small amount of tailings further separated from the main tailings flow. It can more finely collect and discharge a small amount of minerals with specific properties or magnetism that may not be completely discharged in the main tailings bucket, thereby improving the integrity and accuracy of tailings discharge.

[0023] The connecting pipe 16 is arranged on the connecting seat. During operation, since the connecting pipe 16 is prone to blockage, a quick disassembly structure is designed at the connection between the connecting pipe 16 and the connecting seat. When disassembling, the outer part of the handle 19 is pinched by fingers, and the buckle ring 18 is driven to achieve synchronous reversal by reverse rotation, so that the buckle ring 18 is screwed out of the fastener 17. By unfolding the fastener 17 outward, it is convenient to remove the connecting pipe 16 from the connecting seat, which is convenient for manual cleaning of the interior. This design is conducive to improving the convenience of disassembly during cleaning. When cleaning is completed, the two ends of the connecting pipe 16 are connected On the connecting seat, the fastener 17 is fastened to the end position of the connecting pipe 16, and then the buckle 18 is sleeved on the position of the fastener 17. The handle 19 is pinched with fingers and rotated forward to achieve the locking effect, which is conducive to quickly solving the blockage problem. At the same time, it will not affect the magnetic separation operation for a long time, and improves the operation efficiency. The positioning ring 20 is arranged on the connecting seat, and a positioning hole 21 is opened on the positioning ring 20. The positioning pin 22 is inserted and limited to the outside of the handle 19, thereby achieving a stable installation effect and avoiding slipping. It ensures the overall stability and further improves safety.

[0024] Example 2: Figure 4-Figure 7 As shown, the connecting pipe 16 is provided with an injection pipe 23, and a plurality of high-pressure injection nozzles 27 are evenly distributed at the bottom of the injection pipe 23, and the high-pressure injection nozzles 27 all penetrate the inner side of the top of the connecting pipe 16, and the top of the injection pipe 23 is fixedly connected to a connecting pipe 24, and the top of the connecting pipe 24 is fixedly connected to a booster air pump 25, and the top of the booster air pump 25 is connected to an air inlet 26.

[0025] In this embodiment, a plurality of high-pressure jet nozzles 27 are distributed through the bottom of the jet pipe 23 and penetrate the inner side of the top of the connecting pipe 16. A booster air pump 25 and an air inlet 26 are connected to the middle of the jet pipe 23 through a connecting pipe 24, so that the booster air pump 25 can extract and compress air to generate high-pressure gas, and transport it to the jet pipe 23 through the connecting pipe 24. The high-pressure jet nozzle 27 is used to spray high pressure into the interior of the connecting pipe 16, which is beneficial to blowing through high-pressure gas when there is a slight blockage, thereby improving the flow efficiency and reducing the occurrence of blockage.

[0026] Example 3: Figure 1-Figure 7As shown, a flushing pipe 1 is provided on the magnetic separator body 15, a small water pipe 6 and a large water pipe 7 are provided at one end of the bottom of the flushing pipe 1, and the large water pipe 7 is arranged on the side of the small water pipe 6. A medium ore pulse mechanism 8 is provided on one side of the magnetic separator body 15, a frame 9 is provided at the bottom of the magnetic separator body 15, and the medium ore pulse mechanism 8 is arranged on one side of the frame 9. A medium ore bucket 10 is provided at the bottom of the magnetic separator body 15, and the medium ore bucket 10 is arranged in the middle of the frame 9. A gear 11 is provided on the side of the magnetic separator body 15, a medium bin 12 is provided on the inner side of the magnetic separator body 15, a power machine 13 is provided on the outer side of the magnetic separator body 15, and a motor 14 is installed on the side of the power machine 13. A rotating seat is provided at the bottom of the fastener 17, and the rotating seat is installed on the top of the connecting seat.

[0027] In this embodiment, the flushing pipe 1 cooperates with the small water pipe 6 and the large water pipe 7, and its main function is to flush the mineral after the mineral is adsorbed on the cylindrical surface of the magnetic separator. The high-pressure water flow sprayed by the flushing pipe 1 can wash away the non-magnetic mineral particles or other impurities adsorbed on the surface of the magnetic mineral, thereby improving the grade of the concentrate. The large water pipe 7 is mainly used to transport a large amount of water into the magnetic separator to dilute the ore pulp entering the magnetic separator. Appropriate ore pulp concentration is crucial to the magnetic separation effect. By adjusting the amount of water added by the large water pipe 7, the ore pulp can reach the optimal concentration range, ensuring that the mineral particles can be fully dispersed in the ore pulp, which is conducive to the adsorption of magnetic minerals by the magnetic field. The function of the small water pipe 6 is to accurately adjust and supplement the amount of water in the magnetic separator. During the magnetic separation process, the ore pulp concentration or liquid level may change slightly due to various factors. The small water pipe 6 can add an appropriate amount of water to the magnetic separator at a smaller flow rate according to the actual situation, so that the ore pulp concentration and liquid level remain in the optimal state. The intermediate ore pulse mechanism 8 can generate periodic pulse force, so that the magnetic minerals in the slurry are affected by additional pulse force under the action of the magnetic field. This pulse force can enhance the adsorption force between the magnetic minerals and the surface of the magnetic separator cylinder or the magnetic medium, so that the magnetic minerals are more firmly adsorbed on it, and the magnetic minerals are reduced from falling off during the slurry flow process, thereby improving the recovery rate of the magnetic minerals. The intermediate ore bucket 10 is located at a suitable position of the magnetic separator and is used to collect minerals after the magnetic separation process. When the magnetic separator sorts the slurry, the magnetic minerals are adsorbed on the surface of the cylinder and other components, and enter the intermediate ore bucket 10 after washing and other links; non-magnetic minerals or minerals with weak magnetism will also enter the intermediate ore bucket 10 under the action of the slurry flow. The intermediate ore bucket 10 can ensure that the minerals are effectively collected and prevent the minerals from being scattered and lost. The primary function of the medium bin 12 is to store a sufficient amount of magnetic separation media, such as magnetic iron powder, iron sand, etc. These media are key elements in the magnetic separation process. The medium bin 12 can ensure that there is a continuous and stable supply of media during the operation of the magnetic separator to meet the continuity requirements of production.

[0028] In the present invention, when the high gradient magnetic separator is in use, the main function of the slurry inlet 3 is to provide the slurry material to be selected for the magnetic separator body 15. After the mined ore is processed in the early stage such as crushing and grinding, it is prepared into the form of slurry, and transported to the inside of the magnetic separator body 15 through the slurry inlet 3, so that the magnetic separator body 15 can separate the magnetic minerals therein. The primary function of the concentrate trough discharge port 2 is to provide a discharge channel for these concentrates, so that the magnetic minerals after magnetic separation and enrichment can smoothly leave the magnetic separator and enter the subsequent further selection, dehydration, smelting, etc. The main function of the tailings bucket discharge port 4 is to discharge the tailings such as non-magnetic minerals and minerals with weak magnetism that are not magnetically adsorbed during the magnetic separation process from the magnetic separator body 15. After magnetic separation, the minerals that cannot be adsorbed into the concentrate will fall into the tailings bucket and be discharged through the tailings bucket discharge port 4, thereby separating the tailings from the magnetic minerals and completing the magnetic separation process. The flushing pipe 1 cooperates with the small water pipe 6 and the large water pipe 7, and its main function is to flush the minerals after they are adsorbed onto the cylinder surface of the magnetic separator. The high-pressure water flow sprayed by the flushing pipe 1 can wash away the non-magnetic mineral particles or other impurities adsorbed on the surface of the magnetic mineral, thereby improving the grade of the concentrate. The connecting pipe 16 is arranged on the connecting seat. During operation, since the connecting pipe 16 is prone to blockage, a quick disassembly structure is designed at the installation connection between the connecting pipe 16 and the connecting seat. When disassembling, the fingers pinch the outer part of the handle 19, and through reverse rotation, the buckle 18 is driven to achieve synchronous reversal, so that the buckle 18 is unscrewed from the fastener 17. By unfolding the fastener 17 to the outside, it is convenient to remove the connecting pipe 16 from the connecting seat, which is convenient for manual cleaning of the interior. This design is conducive to improving the convenience of disassembly during cleaning. The positioning ring 20 is arranged on the connecting seat. A positioning hole 21 is provided on the positioning ring 20, and the positioning pin 22 is inserted and limited to the outside of the handle 19, thereby achieving a stable installation effect and avoiding slipping, ensuring the overall stability and further improving safety. A number of high-pressure jet nozzles 27 are distributed at the bottom of the jet pipe 23 and penetrate the top inner side of the connecting pipe 16. The booster air pump 25 and the air inlet 26 are connected to the middle of the jet pipe 23 through a connecting pipe 24, which is conducive to the booster air pump 25 to extract and compress air to generate high-pressure gas, and transport it to the jet pipe 23 through the connecting pipe 24. The high-pressure jet nozzle 27 is used to spray high pressure into the interior of the connecting pipe 16, which is conducive to blowing with high-pressure gas when there is a slight blockage, thereby improving the flow efficiency and reducing the occurrence of blockage.
