A nozzle is provided on the upper part of the outer cylinder, and one end of the nozzle is connected to the water pump. The water pump is connected to the sewage tank, and grinding balls are provided in the conveying screen cylinder.

[0010] Furthermore, a separation component is provided on one side of the water tank, and the separation component includes a slow flow tank and an overflow port. A slow flow tank is provided on one side of the water tank, and an overflow port is provided on one side of the slow flow tank.

[0011] Furthermore, the separation component also includes a magnetic separation cylinder and a transmission wheel. The magnetic separation cylinder is rotatably connected in the slow flow tank, and one side of the magnetic separation cylinder is connected to the transmission wheel.

[0012] Furthermore, the separation component also includes a driving wheel and a driving motor. The driving wheel is provided on one side of the transmission wheel, and the driving motor is connected to one side of the driving wheel. The driving wheel is meshed with the transmission wheel.

[0013] Furthermore, the separation component also includes a through groove, an axle, a support plate, a guide groove and a strong magnetic plate. The magnetic separation cylinder and the middle part of the transmission wheel are both provided with a through groove, and the axle is fitted in the through groove.

[0014] Furthermore, the separation component also includes a magnetic suction groove, an empty groove, a return spring and a material baffle plate.

The baffle plate is clamped and connected to the magnetic separation cylinder through the magnetic suction grooves, and the baffle plate is elastically connected to the magnetic separation cylinder through a reset spring. The baffle plate is made of non-magnetic material.

[0016] The present invention provides a lithium ore strong magnetic tailings extraction device, which has the following beneficial effects: when in use, the tailings can be cleaned first, the soil or dust adhering to the surface can be removed, and the sewage generated by the cleaning can be reused. While the crushing component is cleaned, the tailings can be prevented from remaining or accumulating in the crushing component, and the material can also be automatically separated and transported during magnetic separation.

[0017] 1. When the present invention is in use, the lithium ore tailings are poured onto the sieve plate and washed with water at the same time, so that the soil and dust adhering to the tailings can be washed away, so that the sewage penetrates the sieve plate and enters the sewage tank along the guide plate. Under the impact of the water flow, the sieve plate can compress the vibration spring, so that the vibration spring drives the sieve plate to vibrate repeatedly on the sewage tank, so that the cleaned tailings move along the sieve plate, and the limit plate can limit the sieve plate through the air box to prevent the sieve plate from deflecting during vibration. The baffle can prevent the material from falling from the sieve plate during vibration. When the sieve plate drives the limit plate to move, it can synchronously drive the air plate in the air box. The air in the air box is compressed, and the air plate limits the amplitude of the sieve plate under the action of air pressure and the air box. After the sewage enters the sewage tank, it will be blocked by the partition first, and then slowly rise on one side of the partition, so that the impurities in the sewage are precipitated on one side of the partition, and the clean water rises and flows over the upper end of the partition to the other side of the partition, waiting to be extracted and used. After flushing for a period of time, the sewage outlet can be opened to remove the precipitated impurities. In summary, when in use, the tailings can be cleaned, the mud or dust adhering to its surface can be removed, and the sewage generated by cleaning can be reused.

[0018] 2. In the present invention, after the tailings slide down from the screen plate, the guide plate can receive the tailings and make the tailings slide into the outer cylinder along the guide plate. After the tailings fall from the guide plate, they enter the screen drum, and at the same time, the crushing motor drives the screen drum to rotate in the outer cylinder, so that the grinding balls in the screen drum crush the tailings, and under the action of centrifugal force and gravity, the crushed tailings are discharged from the screen drum through the sieve holes on the surface of the screen drum. At the same time, the water pump draws out the clean water from the partition plate in the sewage tank close to the water pump side, and sprays the clean water into the outer cylinder through the nozzle to flush the screen drum, and flush the tailings adhered to the inner wall of the outer cylinder and the outer wall of the screen cylinder. At the same time, the water flows into the screen cylinder through the sieve holes to flush the inside of the screen cylinder, and flushes out the tailings adhered to the inner wall of the screen cylinder and the grinding balls. The water flow carries the tailings away from the outer cylinder from the discharging trough and flows into the water tank, waiting for magnetic separation. In summary, when in use, the crushing component can be cleaned with the sewage generated by cleaning, and at the same time, tailings can be avoided from remaining or accumulating in the crushing component.

[0019] 3. In the present invention, after the water flow carries the tailings into the water tank, it flows into the slow flow tank along the water tank, so that the water flow rate is reduced and buffered in the slow flow tank. At the same time, the driving motor drives the transmission wheel to rotate through the driving wheel, so that the magnetic separation drum rotates in the slow flow tank against the direction of the water flow, so that the strong magnetic plate adsorbs the magnetic material into the magnetic suction tank, and the material baffle plate blocks the material to prevent the material from being directly adsorbed onto the strong magnetic plate. With the rotation of the magnetic separation drum, the material remains in the magnetic suction tank, and the water flows out of the magnetic suction tank. When the magnetic suction tank adsorbed with the material rotates to the top of the support plate with the magnetic separation drum, the material baffle plate is moved under the action of the gravity of the material and the magnetic plate. The suction groove rotates and stretches the reset spring, so that the material can slide from the baffle plate to the support plate under the action of gravity, and slide along the support plate to the shaft rod, and finally leave the magnetic separation cylinder from the shaft rod along the guide groove. As the magnetic separation cylinder rotates, the baffle plate can be re-engaged with the magnetic separation cylinder through the magnetic suction groove under the action of gravity and the reset spring before entering the water, so as to facilitate the adsorption of magnetic materials again. After the water level in the slow flow trough rises, it can leave the slow flow trough along the overflow port to avoid water overflow from both sides of the trough. In summary, when in use, the water flow rate can be slowed down, the magnetic separation effect can be enhanced, and the material can be automatically separated and transported.

[0030] The specific operation is as follows. When in use, the lithium ore tailings are poured onto the sieve plate 209 and washed with water at the same time, so that the dirt and dust adhering to the tailings can be washed away, so that the sewage penetrates the sieve plate 209 and enters the sewage tank 201 along the guide plate 203. Under the impact of the water flow, the sieve plate 209 can compress the vibration spring 202, so that the vibration spring 202 drives the sieve plate 209 to vibrate repeatedly on the sewage tank 201, so that the cleaned tailings move along the sieve plate 209, and the limit plate 208 can limit the sieve plate 209 through the air box 206 to prevent the sieve plate 209 from deflecting during the vibration, and the baffle 210 can prevent the material from vibrating during the vibration.

After flushing for a period of time, the sewage outlet 205 can be opened. The precipitated impurities are removed. In summary, when in use, the tailings can be cleaned, the mud or dust adhering to the surface can be removed, and the sewage generated by cleaning can be reused. After the tailings slide from the screen plate 209, the guide plate 402 can receive the tailings and make the tailings slide into the outer cylinder 401 along the guide plate 402. After the tailings fall from the guide plate 402, they enter the screen cylinder 404. At the same time, the crushing motor 405 drives the screen cylinder 404 to rotate in the outer cylinder 401, so that the grinding balls in the screen cylinder 404 crush the tailings, and the crushed tailings are discharged from the screen cylinder 404 through the sieve holes on the surface of the screen cylinder 404 under the action of centrifugal force and gravity. At the same time, water flows into the sieve cylinder 404 through the sieve holes, flushes the inside of the sieve cylinder 404, flushes the tailings adhered to the inner wall of the sieve cylinder 404 and the grinding balls, and carries out the tailings leaving the outer cylinder 401 from the discharge trough 403 and flowing into the water tank 3, waiting for magnetic separation.

The separation component 5 also includes a driving wheel 505 and a driving motor 506. The driving wheel 504 is provided on one side, and the driving wheel 505 is connected to the driving motor 506. The driving wheel 505 is meshed with the driving wheel 504. The separation component 5 also includes a through groove 507, an axle 508, a support plate 509, a guide groove 510 and a strong magnetic plate 511. A through groove 507 is provided in the middle of the magnetic separation cylinder 503 and the transmission wheel 504, and an axle is fitted in the through groove 507. The shaft 508 is symmetrically connected to support plates 509 on both sides, and a guide groove 510 is provided on one side of the shaft 508. A strong magnetic plate 511 is provided between the support plates 509 below the shaft 508. The separation component 5 also includes a magnetic suction groove 512, an empty groove 513, a reset spring 514 and a material blocking plate 515. The surface of the magnetic separation cylinder 503 is provided with a magnetic suction groove 512, and an empty groove 513 is provided on one side of the magnetic suction groove 512. The empty groove 513 A return spring 514 is connected inside, and the other end of the return spring 514 is connected to a baffle plate 515. The magnetic suction grooves 512 are equidistantly distributed on the magnetic separation cylinder 503, and the baffle plate 515 is rotatably connected to the magnetic suction grooves 512. The baffle plate 515 is engaged with the magnetic separation cylinder 503 through the magnetic suction grooves 512, and the baffle plate 515 is elastically connected to the magnetic separation cylinder 503 through the return spring 514. The baffle plate 515 is made of non-magnetic material;

[0032] The specific operation is as follows: after the water flow carries the tailings into the water tank 3, it flows into the slow flow tank 501 along the water tank 3, so that the water flow rate is reduced and buffered in the slow flow tank 501, and at the same time, the driving motor 506 drives the transmission wheel 504 to rotate through the driving wheel 505, so that the magnetic separation cylinder 503 rotates in the slow flow tank 501 against the direction of the water flow, so that the strong magnetic plate 511 adsorbs the magnetic material into the magnetic suction groove 512, and the baffle plate 515 blocks the material to prevent the material from being directly adsorbed onto the strong magnetic plate 511. As the magnetic separation cylinder 503 rotates, the material remains in the magnetic suction groove 512, and the water flows out of the magnetic suction groove 512. When the magnetic suction groove 512 adsorbed with the material rotates to the top of the support plate 509 with the magnetic separation cylinder 503, under the action of the baffle plate 515 and the gravity of the material, the baffle plate 5 15 rotates in the magnetic suction groove 512 and stretches the return spring 514, so that the material can slide from the baffle plate 515 to the support plate 509 under the action of gravity, and slide along the support plate 509 to the shaft rod 508, and finally leave the magnetic separation cylinder 503 from the shaft rod 508 along the guide groove 510. As the magnetic separation cylinder 503 rotates, the baffle plate 515 can re-engage with the magnetic separation cylinder 503 through the magnetic suction groove 512 under the action of gravity and the return spring 514 before entering the water, so as to facilitate the adsorption of the magnetic material again. After the water level in the slow flow groove 501 rises, it can leave the slow flow groove 501 along the overflow port 502 to avoid water overflow from both sides of the water groove 3. In summary, when in use, the water flow rate can be slowed down, the magnetic separation effect can be enhanced, and the material can be automatically separated and transported.

[0033] In summary, when using the lithium ore strong magnetic tailings extraction device, the lithium ore tailings are first dumped onto the sieve plate 209, and then rinsed with water to wash away the mud and dust adhering to the tailings, so that the sewage penetrates the sieve plate 209 and enters the sewage tank 201 along the guide plate 203. Under the impact of the water flow, the sieve plate 209 can compress the vibration spring 202, so that the vibration spring 202 drives the sieve plate 209 to vibrate repeatedly on the sewage tank 201, so that the cleaned tailings move along the sieve plate 209, and the limit plate 208 can limit the sieve plate 209 through the air box 206 to prevent the sieve plate 209 from deflecting during the vibration. The baffle 210 can prevent the material from falling from the sieve plate 209 during the vibration process. When the plate 208 moves, it can synchronously drive the air plate 207 to move in the air box 206, thereby compressing the air in the air box 206, and then the air plate 207 limits the amplitude of the sieve plate 209 under the action of the air pressure and the air box 206. After the sewage enters the sewage tank 201, it will be blocked by the partition 204 first, and then slowly rise on one side of the partition 204, so that the impurities in the sewage are precipitated on one side of the partition 204, and the clean water rises and flows over the upper end of the partition 204 to the other side of the partition 204, waiting to be extracted and used. After flushing for a period of time, the sewage outlet 205 can be opened to remove the precipitated impurities. After the tailings slide off the sieve plate 209, the guide plate 402 can receive the tailings and make the tailings slide along the guide plate 402 into The tailings fall from the guide plate 402 and enter the screen drum 404. At the same time, the crushing motor 405 drives the screen drum 404 to rotate in the outer cylinder 401, so that the grinding balls in the screen drum 404 crush the tailings, and discharge the crushed tailings from the screen drum 404 through the sieve holes on the surface of the screen drum 404 under the action of centrifugal force and gravity. At the same time, the water pump 407 draws out the clean water from the side of the partition 204 in the sewage tank 201 close to the water pump 407, and sprays it into the outer cylinder 401 through the nozzle 406, flushing the screen drum 404, and flushing the tailings adhered to the inner wall of the outer cylinder 401 and the outer wall of the screen drum 404. At the same time, the water flows into the screen drum 404 through the sieve holes, flushing the inside of the screen drum 404, and flushing out the tailings adhered to the inner wall of the screen drum 404 and the grinding balls. The tailings are carried by the flow and leave the outer cylinder 401 from the discharge trough 403, and flow into the slow flow trough 501 along the water trough 3, so that the water flow velocity is reduced and buffered in the slow flow trough 501. At the same time, the driving motor 506 drives the transmission wheel 504 to rotate through the driving wheel 505, so that the magnetic separation cylinder 503 rotates in the slow flow trough 501 against the direction of the water flow, so that the strong magnetic plate 511 adsorbs the magnetic material into the magnetic suction groove 512, and the baffle plate 515 blocks the material to prevent the material from being directly adsorbed on the strong magnetic plate 511. As the magnetic separation cylinder 503 rotates, the material remains in the magnetic suction groove 512, and the water flows out of the magnetic suction groove 512. When the magnetic suction groove 512 adsorbed with the material rotates to the top of the support plate 509 with the magnetic separation cylinder 503, under the action of the baffle plate 515 and the gravity of the material,The baffle plate 515 rotates in the magnetic suction groove 512 and stretches the reset spring 514, so that the material can slide from the baffle plate 515 to the support plate 509 under the action of gravity, and slide along the support plate 509 to the shaft 508, and finally leave the magnetic separation cylinder 503 from the shaft 508 along the guide groove 510. As the magnetic separation cylinder 503 rotates, the baffle plate 515 can re-engage with the magnetic separation cylinder 503 through the magnetic suction groove 512 under the action of gravity and the reset spring 514 before entering the water, so as to facilitate the adsorption of magnetic materials again. After the water level in the slow flow groove 501 rises, the material can leave the slow flow groove 501 along the overflow port 502 to prevent the water from overflowing from both sides of the water tank 3.
