Description

Technical Field

[0001] The invention relates to the technical field of lithium ore magnetic separators, and in particular to a waste discharge mechanism of a lithium ore magnetic separator. Background Art

[0002] A lithium ore magnetic separator is a device used to extract lithium from lithium ore. It uses magnetic differences to separate lithium minerals from other minerals in the ore. By processing the ore in a magnetic field, lithium-containing minerals can be separated from other ores. This equipment plays an important role in the process of extracting lithium ore, helping to improve ore extraction efficiency and reduce production costs.

[0003] For example, the patent with publication number CN220091687U discloses a waste discharge mechanism of a lithium ore magnetic separator. The patent sets a waste discharge device, in which the second motor, the slide, the threaded rod and the second connecting shaft can drive the slider to move the waste discharge plate toward the direction close to the round roller, so that the waste discharge plate can scrape the impurities adsorbed on the round roller and introduce these impurities into the waste discharge slot, and the impurities are discharged downward through the waste discharge slot, thereby effectively cleaning the impurities on the round roller. However, in the actual use of such devices, since the round roller has magnetism, when the waste discharge plate approaches the round roller and scrapes the outside of the round roller, once the waste moves to the waste discharge plate, the waste will be affected by the magnetic attraction of the round roller, so that it stays in the waste discharge slot and will not be completely discharged, resulting in the problem of easy blockage during use.

[0016] The present invention provides a waste discharge mechanism for a lithium ore magnetic separator, which has the following beneficial effects:

[0017] 1. In the present invention, when the strong magnetic waste adheres to the outside of the magnetic roller, the top side of the scraper frame fits with the outside of the magnetic roller. Therefore, as the magnetic roller rotates, the waste can be transferred to the end of the scraper frame. At this time, the waste will adhere to the lower end of one side of the scraper frame under the action of the magnetic attraction force. Then, when the double-axis motor is started, the bevel gear set will drive the reciprocating screw to rotate, so that the moving seat moves toward the magnetic roller. In this process, the moving seat will first push the transmission plate through the driving column. At this time, there is friction between the slide seat and the scraper frame, and it will not move temporarily. Therefore, the transmission plate can rotate the push plate a quarter of a turn through the connecting shaft, so that the push plate It is parallel to the top of the scraper frame. Later, when the transmission plate cannot rotate, the transmission plate will pull the sliding seat through the connecting shaft to move it toward the magnetic roller. Therefore, in the process of the pushing plate moving toward the magnetic roller, the pushing plate will not push the waste. When the moving seat moves in the opposite direction, similarly, the moving seat will first pull the transmission plate through the driving column to make the connecting shaft drive the pushing plate to rotate perpendicular to the bottom of the scraper frame. At this time, the pushing plate can push the waste away from the magnetic roller during the movement. After reducing the influence of magnetism, the waste will fall under the action of gravity and be discharged from the waste discharge port, thereby avoiding the continuous accumulation of waste on one side of the scraper frame, which is beneficial to improve the waste discharge effect.

[0018] 2. In the present invention, since the top height of the gear lever is slightly lower than the center height of the pulley, the gear lever will limit the bottom of the pulley during the reciprocating movement of the moving seat, so that the pulley can drive the moving seat to move upward. At this time, the fixed rod will limit the top position of the telescopic rod, so the vibration spring will be compressed, and when the pulley is separated from the gear lever, the vibration spring will release the stored mechanical energy, thereby causing the scraper frame to vibrate. At the same time, multiple gear levers are provided to increase the duration of the vibration of the scraper frame so as to shake off the waste adhered to the inner wall of the scraper frame, thereby enhancing the effect of waste discharge. At the same time, since the scraper frame is rotatably connected to the box body through the positioning shaft, it rotates when vibrating, and the scraper frame and the magnetic roller are in contact with the axis of the positioning shaft. Therefore, when the scraper frame swings and vibrates, the scraper frame will always be in contact with the magnetic roller, which is beneficial to reduce the impact on the scraping operation.

[0019] 3. In the present invention, when the material is added into the box from the feed port, it will first fall onto the magnetic roller. During this process, some waste particles with strong magnetism may press the lithium ore particles with weak magnetism onto the magnetic roller, so that some lithium ore particles cannot fall freely. At this time, when the magnetic roller rotates, it will also drive the driving wheel to rotate synchronously, and the limit rod will limit the two sides of the driving plate. Therefore, during the rotation of the driving wheel, the guide groove will push the sliding column, so that the driving plate will push and pull the sliding rod back and forth, so that the separation plate can adjust the position of the particles attached to the outside of the magnetic roller during the swinging process, so as to loosen and separate some lithium ore particles from the waste particles, thereby improving the effect of magnetic separation.

[0020] 4. According to the present invention, when the movable seat moves away from the magnetic roller, it will contact the slide plate, and the airbag will shrink in the process of squeezing the slide plate. At the same time, the baffle can prevent the airbag from bending upward, and the air inside the airbag will be sprayed out from the nozzle on the jet pipe through the fixed tube, the second one-way valve, the hose, and the diverter tube to clean the lower end of the box body by jetting, so as to prevent the waste from adhering to the inner wall of the box body, and make the waste discharge more thorough. In the process of the movable seat moving toward the magnetic roller, the return spring will push the slide plate under the limit of the guide rod, so as to stretch the airbag, and the external air will be replenished into the airbag through the hose, the first one-way valve and the fixed tube under the filtration of the filter cover, so that the discharge component can be reused.

[0031] The specific operation is as follows: when the material is added into the box body 1 from the feed port 2, it will first fall onto the magnetic roller 4. During this process, some waste particles with strong magnetism may press the lithium ore particles with weak magnetism onto the magnetic roller 4, so that some lithium ore particles cannot fall freely. At this time, when the driving motor 3 drives the magnetic roller 4 to rotate, it will also drive the driving wheel 701 to rotate synchronously, and the limiting rod 705 will limit the two sides of the driving plate 704.

In addition, since the top side of the scraper frame 8 is in contact with the outside of the magnetic roller 4, the waste can be transferred to the end of the scraper frame 8 as the magnetic roller 4 rotates. At this time, the waste will adhere to the lower end of one side of the scraper frame 8 under the action of the magnetic attraction force. Then, when the dual-axis motor 901 is started, the bevel gear set 902 drives the reciprocating screw 903 to rotate, so that the moving seat 904 moves toward the magnetic roller 4. During this process, the moving seat 904 will first push the transmission plate 906 through the driving column 905. At this time, there is friction between the slide 909 and the scraper frame 8, and it will not move temporarily. Therefore, the transmission plate 906 can rotate the push plate 908 a quarter of a circle through the connecting shaft 907, so that the push plate 908 is parallel to the top of the scraper frame 8. Later, when the transmission plate 906 cannot rotate, the transmission plate 906 will pull the slide through the connecting shaft 907. 909, so that it moves toward the magnetic roller 4. Therefore, in the process of the push plate 908 moving toward the magnetic roller 4, the push plate 908 will not push the waste. When the movable seat 904 moves in the opposite direction, similarly, the movable seat 904 will first pull the transmission plate 906 through the driving column 905, so that the connecting shaft 907 drives the push plate 908 to rotate perpendicular to the bottom of the scraper frame 8. At this time, the push plate 908 can push the waste away from the magnetic roller 4 during the movement. After reducing the influence of magnetism, the waste will fall under the action of gravity and be discharged from the waste discharge port 6.

[0033] The specific operation is as follows. During the reciprocating movement of the moving seat 904, the gear lever 1007 will limit the bottom of the pulley 1005, so that the pulley 1005 can drive the moving seat 904 to move upward. At this time, the fixed rod 1004 will limit the top position of the telescopic rod 1002, so the vibration spring 1003 will be compressed, and when the pulley 1005 is separated from the gear lever 1007, the vibration spring 1003 will release the stored mechanical energy, thereby causing the scraper frame 8 to vibrate, so as to shake off the waste adhered to the inner wall of the scraper frame 8. At the same time, since the scraper frame 8 is rotatably connected to the box body 1 through the positioning shaft 1001, it is a rotational vibration when vibrating, and the scraper frame 8 and the magnetic roller 4 are attached at the same straight line as the axis of the positioning shaft 1001. Therefore, when the scraper frame 8 swings and vibrates, the scraper frame 8 will always be in contact with the magnetic roller 4, which is beneficial to reduce the impact on the scraping operation. At the same time, when When the movable seat 904 moves away from the magnetic roller 4, it will contact the slide plate 1104, and the airbag 1102 will shrink in the process of squeezing the slide plate 1104. At the same time, the baffle 1103 can prevent the airbag 1102 from bending upward. The air inside the airbag 1102 will pass through the fixed tube 1101, the one-way valve 1108, the hose 1109, and the diversion tube 1111 to be sprayed out from the nozzle on the jet pipe 1112 to spray and clean the lower end of the box body 1, so as to prevent waste from adhering to the inner wall of the box body 1, and make the waste discharge more thorough. In the process of the movable seat 904 moving toward the magnetic roller 4, the return spring 1106 will push the slide plate 1104 under the limit of the guide rod 1105, so as to stretch the airbag 1102, and the external air will be filtered by the filter cover 1110 through the hose 1109, the one-way valve 1107 and the fixed tube 1101 to replenish the airbag 1102.

[0034] In summary, when the waste discharge mechanism of the lithium ore magnetic separator is used, first, the material is added into the box body 1 from the feed port 2, and the material will first fall onto the magnetic roller 4, and the waste particles with strong magnetism will be adsorbed by the magnetic roller 4, while the lithium ore particles with weak magnetism will be discharged from the discharge port 5 under the action of gravity. At the same time, some waste particles with strong magnetism may press the lithium ore particles with weak magnetism onto the magnetic roller 4, so that some lithium ore particles cannot fall freely. At this time, when the driving motor 3 drives the magnetic roller 4 to rotate, it will also drive the driving wheel 701 to rotate synchronously, and the limiting rod 705 will limit the two sides of the driving plate 704. Therefore, during the rotation of the driving wheel 701, the guide groove 702 will push the sliding column 703, so that the driving plate 704 pushes and pulls the sliding rod 704 back and forth. 6, the separation plate 707 can adjust the position of the particles attached to the outside of the magnetic roller 4 during the swinging process, so as to separate some lithium ore particles from the waste. Then, since the top side of the scraper frame 8 is in contact with the outside of the magnetic roller 4, the waste can be transferred to the end of the scraper frame 8 as the magnetic roller 4 rotates. At this time, the waste will adhere to the lower end of one side of the scraper frame 8 under the action of the magnetic attraction force. Then, when the dual-axis motor 901 is started, the bevel gear set 902 will drive the reciprocating screw 903 to rotate, so that the moving seat 904 moves toward the magnetic roller 4. In this process, the moving seat 904 will first push the transmission plate 906 through the driving column 905. At this time, there is friction between the slide seat 909 and the scraper frame 8, and it will not move temporarily, so the transmission can be Plate 906 rotates the push plate 908 a quarter of a turn through the connecting shaft 907, so that the push plate 908 is parallel to the top of the scraper frame 8. Then, when the transmission plate 906 cannot rotate, the transmission plate 906 will pull the slide seat 909 through the connecting shaft 907 to move it toward the magnetic roller 4. At the same time, when the moving seat 904 moves toward the magnetic roller 4, the return spring 1106 will push the slide plate 1104 under the limit of the guide rod 1105, so as to stretch the airbag 1102. The external air will be filtered by the filter cover 1110 through the hose 1109, the one-way valve 1107 and the fixed pipe 1101 to replenish the airbag 1102. Secondly, when the moving seat 904 moves in the opposite direction, similarly, the moving seat 904 will first pull the drive column 905 to The transmission plate 906 is moved, so that the connecting shaft 907 drives the push plate 908 to rotate perpendicular to the bottom of the scraper frame 8. At this time, the push plate 908 can push the waste away from the magnetic roller 4 during the movement. After reducing the influence of the magnetism, the waste will fall under the action of gravity and be discharged from the waste discharge port 6. Then, since the top height of the gear lever 1007 is slightly lower than the center height of the pulley 1005, during the reciprocating movement of the moving seat 904, the gear lever 1007 will limit the bottom of the pulley 1005, so that the pulley 1005 can drive the moving seat 904 to move upward. At this time, the fixed rod 1004 will limit the top position of the telescopic rod 1002, so the vibration spring 1003 will be compressed, and when the pulley 1005 is separated from the gear lever 1007,The vibration spring 1003 will release the stored mechanical energy, so that the scraper frame 8 will vibrate, so as to shake off the waste adhered to the inner wall of the scraper frame 8, thereby enhancing the effect of waste discharge. At the same time, since the scraper frame 8 is rotatably connected to the box body 1 through the positioning shaft 1001, it is a rotational vibration when vibrating, and the contact point between the scraper frame 8 and the magnetic roller 4 is located on the same straight line as the axis of the positioning shaft 1001. Therefore, when the scraper frame 8 swings and vibrates, the scraper frame 8 will always be in contact with the magnetic roller 4. Finally, when the moving seat 904 When moving away from the magnetic roller 4, it will contact the slide plate 1104, and in the process of squeezing the slide plate 1104, the airbag 1102 will shrink. At the same time, the baffle 1103 can prevent the airbag 1102 from bending upward. The air inside the airbag 1102 will be ejected from the nozzle on the jet pipe 1112 through the fixed pipe 1101, the one-way valve 1108, the hose 1109, and the diverter pipe 1111 to jet and clean the lower end of the box body 1, preventing waste from adhering to the inner wall of the box body 1, making the waste discharge more thorough.
