The bottom center of the rotating plate 6 is connected to the output end of the motor 7, and the output end of the motor 7 drives the rotating plate 6 to rotate inside the tank body 2. A screening frame 8 is arranged on the top of the rotating plate 6. An inner film frame 9 is laid inside the screening frame 8. The inner film frame 9 is set as an elastic filter membrane. The inner film frame 9 carries rare earth raw materials. The inner film frame 9 is provided with a mounting component fixed with the screening frame 8 and the inner film frame 9. The screening frame 8 is fixedly mounted on the top of the rotating plate 6 by the mounting component. The cover plate 5 blocks the top opening of the screening frame 8, and the surface of the screening frame 8 is provided with a leak hole. A drainage pipe 10 is arranged on one side of the tank body 2. The drainage pipe 10 is made of transparent material, and a blocking component is installed on the drainage pipe 10. A convex plate is arranged at the top opening of the tank body 2, and the bottom surface of the cover plate 5 is in contact with the top surface of the convex plate. The outer circumferential surface of the cover plate 5 is hinged to the top of the tank body 2, and a screw 14 is screwed into the inner side of the convex plate. The cover plate 5 is fixed to the top opening of the tank body 2 by the screw 14. Unscrew the screws 14, and the cover plate 5 rotates on the top of the tank body 2 until the cover plate 5 is opened. The screening frame 8 carrying the inner membrane frame 9 is placed on the top of the rotating plate 6, and the screening frame 8 is fixed to the top surface of the rotating plate 6 by using the mounting components. At this time, the rare earth raw material is passed into the inner side of the inner membrane frame 9, and the cover plate 5 is replaced on the top opening of the tank body 2, and the cover plate 5 is fixed to the top of the tank body 2 by using the screws 14. The relevant distribution parameters (the trough volume of the tank body 2, the separation time) are input through the touch screen 4, so as to calculate the relevant liquid flow rate passed into the inner side of the tank body 2, and the water inside the water tank and the extractant are passed into the inner side of the inner membrane frame 9 through the liquid pipe until the water level inside the tank body 2 reaches a suitable position.

The output end of the motor 7 uses the rotating plate 6 and the mounting components to make the screening frame 8 and the inner film frame 9 rotate bidirectionally on the inner side of the tank body 2. The bidirectional rotation allows the rare earth elements in the rare earth raw material to dissolve into the solution in the form of ions, and the inner film frame 9 and the screening frame 8 prevent block impurities in the rare earth raw material from entering the inner side of the tank body 2.
[0029] After the rare earth solution is stirred for a period of time inside the tank body 2, the rare earth solution is left to stand so that the rare earth elements are stratified inside the tank body 2 by the extractant. The drain pipe 10 is opened to discharge the stratified rare earth solution inside the tank body 2 in sequence, thereby completing the extraction and separation of the rare earth raw materials.

When the cover plate 5 is placed on the top opening of the tank body 2, the outer ring strip 12 on the bottom surface of the cover plate 5 is correspondingly clamped on the top opening of the screening frame 8, the outer ring strip 12 is used to block and limit the top opening of the screening frame 8, and the mounting component limits the bottom end of the screening frame 8, ensuring that the rotating plate 6 drives the screening frame 8 to rotate smoothly inside the tank body 2. At the same time, the cover plate 5 uses the inner ring strip 11 to block the material opening 13 at the top of the inner film frame 9 to prevent the rare earth raw materials from entering the inner side of the inner film frame 9 into the inner side of the tank body 2 and prevent the blocky rare earth raw materials from accumulating inside the tank body 2.
[0031] exist Figure 4 and Figure 5 In the embodiment, a plurality of plug rods 15 are fixed on the top surface of the rotating plate 6, and the top ends of the plug rods 15 pass through the screening frame 8 and the inner film frame 9, and the mounting parts include a ring frame 16, and the bottom end of the ring frame 16 is fixedly connected to the inner bottom surface of the screening frame 8, and the inner film frame 9 is sleeved on the surface of the ring frame 16, and an inner ring 17 is arranged on the inner side of the ring frame 16, and the inner ring 17 is sleeved on the surface of the plug rod 15, and an outer ring 18 is arranged on the outer side of the ring frame 16, and the inner ring 17 is fixedly connected to the outer ring 18 by a connecting strip, and the surface of the ring frame 16 is provided with a side groove corresponding to the connecting strip, and the outer ring 18 is pressed on the inner bottom surface of the inner film frame 9. A rotating frame 19 is arranged on the top of the outer ring 18, and the rotating frame 19 is sleeved on the surface of the ring frame 16, and a sleeve 20 is fixed on the inner side of the rotating frame 19, and the sleeve 20 is spirally sleeved on the top of the plug rod 15, and the bottom surface of the rotating frame 19 is in contact with the top surface of the outer ring 18. The screening frame 8 carrying the inner membrane frame 9 is placed on the top surface of the rotating plate 6. At this time, the insertion rod 15 at the top of the rotating plate 6 corresponds to passing through the screening frame 8 and the inner membrane frame 9, and the bottom surface of the inner membrane frame 9 is correspondingly sleeved on the surface of the ring frame 16. The bottom end of the rotating frame 19 corresponds to the top of the ring frame 16, and the rotating frame 19 is rotated. The rotating rotating frame 19 drives the sleeve 20 to rotate on the surface of the insertion rod 15. The spiral cooperation between the sleeve 20 and the insertion rod 15 makes the sleeve 20 move downward on the outside of the ring frame 16. The downwardly moved sleeve 20 pushes the outer ring 18 and the inner ring 17 to move downward synchronously. The downwardly moved outer ring 18 cooperates to squeeze the inner membrane frame 9 on the inner bottom surface of the screening frame 8 during the downward movement of the outside, so that the bottom of the inner membrane frame 9 is fixedly connected with the bottom of the screening frame 8, avoiding the misaligned rotation of the inner membrane frame 9 and the screening frame 8, and ensuring that the screening frame 8 uses the inner membrane frame 9 to drive the rare earth raw material to rotate synchronously on the inside of the tank body 2.
[0032] The rotating rotating frame 19 makes the bottom surface of the outer ring 18 fit tightly against the inner bottom surface of the inner film frame 9, and the outer ring 18 and the inner film frame 9 cooperate to block the groove on the surface of the ring frame 16 to prevent the rare earth raw materials from entering the inner side of the ring frame 16 and leaking out from the inner side of the inner film frame 9.
[0033] After the rare earth raw materials have been extracted by the tank body 2, the cover plate 5 is opened, the rare earth raw materials become mud blocks and particles adsorbed on the inner wall of the inner membrane frame 9, the rotating frame 19 is rotated in the opposite direction, the rotating frame 19 is removed from the top of the ring frame 16, the screening frame 8 and the inner membrane frame 9 are taken out from the inside of the tank body 2, the inner membrane frame 9 is pulled, the elastic filter membrane is taken out from the inside of the screening frame 8, the inner membrane frame 9 takes out the mud blocks and particles from the inside of the screening frame 8, the inner membrane frame 9 is cleaned, the mud blocks and particles inside the inner membrane frame 9 are collected, the new inner membrane frame 9 is re-installed on the inside of the screening frame 8, and the screening frame 8 is re-installed on the inside of the tank body 2 using the mounting components, so as to facilitate the tank body 2 to continue to extract and separate the rare earth raw materials.
[0034] exist Figure 2 , Figures 6 to 8 In the embodiment, the blocking component includes a gear plate 21, which is located at the input end of the drain pipe 10, and the gear plate 21 blocks the drain pipe 10 accordingly. The top surface of the rotating plate 6 is provided with tooth grooves 22 arranged in an annular manner, and the rotating rotating plate 6 drives the gear plate 21 to rotate by using the tooth grooves 22. A baffle plate 23 is provided inside the output end of the drain pipe 10, and a cross bar 24 penetrating the center of the gear plate 21 is fixed at the center of the inner side surface of the baffle plate 23. The inner end surface of the cross bar 24 is provided with an annular edge 25, and the gear plate 21 is rotatably sleeved on the outer side of the annular edge 25 of the cross bar 24. When the rotating plate 6 rotates, the rotating rotating plate 6 drives the gear plate 21 to rotate on the surface of the annular edge 25 of the cross bar 24 by using the tooth grooves 22, and the cross bar 24 limits the gear plate 21 by using the annular edge 25. The rotating gear plate 21 blocks the input end of the drain pipe 10, and the baffle plate 23 cooperates to block the output end of the drain pipe 10 to prevent the solution inside the tank body 2 from being directly discharged.
[0035] A plurality of supporting rods 26 are fixed to the outer side of the gear plate 21, and the outer ends of the supporting rods 26 are fitted with the inner side of the baffle plate 23. A rubber plate 27 is sleeved on the outer end surface of the supporting rod 26. The rubber plate 27 is spirally sleeved on the surface of the cross bar 24, and the outer circumferential side of the rubber plate 27 is fitted with the inner wall of the discharge pipe 10. When the gear plate 21 rotates, the rotating gear plate 21 drives the rubber plate 27 to rotate on the surface of the cross bar 24 by using the plurality of supporting rods 26. Since the rubber plate 27 is spirally sleeved on the surface of the cross bar 24, and the rotating plate 6 rotates bidirectionally on the inner side of the tank body 2, the rotating rubber plate 27 moves back and forth on the cross bar 24, and the rubber plate 27 is used to scrape the impurities attached to the inner wall of the discharge pipe 10.
[0036] exist Figures 6 to 8In the embodiment, an outer frame 28 is fixed on the discharge pipe 10, a screw 29 penetrating the center of the top surface of the outer frame 28 is fixed on the top surface of the baffle 23, a rotating sleeve 30 is provided on the top surface of the outer frame 28, the rotating sleeve 30 is spirally sleeved on the top of the screw 29, and a ring piece 31 for limiting the rotating sleeve 30 is fixed on the top surface of the outer frame 28. Side rods 32 are fixed on both sides of the baffle 23, and vertical grooves are provided on both sides of the outer frame 28. The baffle 23 slides up and down inside the vertical grooves of the outer frame 28 using the side rods 32. The rotating sleeve 30 is twisted. Since the outer frame 28 uses the ring plate 31 to limit the rotating sleeve 30, the rotating sleeve 30 rotates on the top of the outer frame 28. The spiral cooperation between the rotating sleeve 30 and the screw 29 enables the screw 29 to drive the baffle 23 to move upward. The upward baffle 23 uses the cross bar 24 to drive the gear plate 21 to move upward synchronously. At this time, the gear plate 21 is separated from the rotating plate 6, the gear plate 21 cannot block the input end of the drainage pipe 10, and the baffle 23 cannot block the output end of the drainage pipe 10. The rare earth solution inside the tank body 2 is discharged from the tank body 2 through the drainage pipe 10. The spiral cooperation between the rotating sleeve 30 and the screw 29 is used to adjust the blocking effect of the baffle 23 and the gear plate 21 on the drainage pipe 10 in real time, and the discharge status of the rare earth solution is observed through the transparent drainage pipe 10, so that the layered rare earth solution inside the tank body 2 can be discharged in sequence.
[0037] When the baffle plate 23 drives the gear plate 21 to move upward by means of the cross bar 24 , the cross bar 24 and the support rod 26 squeeze the rubber plate 27 , so that the top of the rubber plate 27 is deformed inside the drain pipe 10 , thereby preventing the rubber plate 27 from blocking the drain pipe 10 .
[0038] Working principle of the present invention:
[0039] Reference Figures 1 to 8 As shown, unscrew the screw 14, the cover plate 5 rotates on the top of the tank body 2 until the cover plate 5 is opened, and the screening frame 8 carrying the inner film frame 9 is placed on the top of the rotating plate 6. At this time, the insertion rod 15 at the top of the rotating plate 6 corresponds to penetrate the screening frame 8 and the inner film frame 9, and the bottom surface of the inner film frame 9 is correspondingly sleeved on the surface of the ring frame 16, and the bottom end of the rotating frame 19 corresponds to the top of the ring frame 16, and the rotating frame 19 is rotated. The rotating rotating frame 19 drives the sleeve 20 to rotate on the surface of the insertion rod 15, and the spiral cooperation of the sleeve 20 and the insertion rod 15 makes the sleeve 20 move downward on the outside of the ring frame 16, and the downwardly moved sleeve 20 pushes the outer ring 18 and the inner ring 17 to move downward synchronously. The downwardly moved outer ring 18 cooperates to squeeze the inner film frame 9 on the inner bottom surface of the screening frame 8 during the downward movement of the outside, so that the bottom of the inner film frame 9 is fixedly connected with the bottom of the screening frame 8, so as to avoid the inner film frame 9 and the screening frame 8 from rotating out of position, and ensure that the screening frame 8 uses the inner film frame 9 to drive the rare earth raw material to rotate synchronously inside the tank body 2.
[0040] The rotating rotating frame 19 makes the bottom surface of the outer ring 18 fit tightly against the inner bottom surface of the inner film frame 9, and the outer ring 18 and the inner film frame 9 cooperate to block the groove on the surface of the ring frame 16 to prevent the rare earth raw materials from entering the inner side of the ring frame 16 and leaking out from the inner side of the inner film frame 9.
[0041] The screening frame 8 is fixed to the top surface of the rotating plate 6 by means of the mounting components. At this time, the rare earth raw material is passed into the inner side of the inner film frame 9, and the cover plate 5 is placed again on the top opening of the tank body 2, and the cover plate 5 is fixed to the top of the tank body 2 by means of the screws 14. The water and the extractant inside the water tank are passed into the inner side of the inner film frame 9 through the liquid pipe until the water level inside the tank body 2 reaches a suitable position. The motor 7 is controlled to work by means of the touch screen 4, and the output end of the motor 7 uses the rotating plate 6 and the mounting components to make the screening frame 8 and the inner film frame 9 rotate bidirectionally inside the tank body 2. The bidirectional rotation allows the rare earth elements in the rare earth raw material to be dissolved into the solution in the form of ions, and the block impurities of the rare earth raw material are blocked from entering the inner side of the tank body 2 by means of the inner film frame 9 and the screening frame 8.
[0042] After the rare earth solution is stirred for a period of time inside the tank body 2, the rare earth solution is allowed to stand still so that the rare earth elements are layered inside the tank body 2 through the extractant. The drain pipe 10 is opened and the rotating sleeve 30 is twisted. Since the outer frame 28 uses the ring sheet 31 to limit the rotating sleeve 30, the rotating sleeve 30 rotates on the top of the outer frame 28. The rotating rotating sleeve 30 and the screw 29 are spirally matched so that the screw 29 drives the baffle plate 23 to move upward. The upward baffle plate 23 drives the gear plate 21 to move upward synchronously using the cross bar 24. At this time, the gear plate 21 and the rotating sleeve 30 are in a state of rotation. Plate 6 is separated, the gear plate 21 cannot block the input end of the drain pipe 10, the baffle plate 23 cannot block the output end of the drain pipe 10, and the rare earth solution inside the tank body 2 is discharged from the tank body 2 through the drain pipe 10. The spiral cooperation between the rotating sleeve 30 and the screw 29 is used to adjust the blocking effect of the baffle plate 23 and the gear plate 21 on the drain pipe 10 in real time, and the discharge status of the rare earth solution is observed through the transparent drain pipe 10, which facilitates the discharge of the layered rare earth solution inside the tank body 2 in sequence, thereby completing the extraction and separation of the rare earth raw materials.
[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
