[0029] See also Figure 2 As shown, the stirring assembly includes a stirring shaft 7, a porous plate 71 and a driving motor 73. The stirring shaft 7 is rotatably connected to the middle of the mounting plate 4. The lower part of the stirring shaft 7 is provided with holes.

The output shaft of the driving motor 73 is connected to the upper part of the stirring shaft 7 through a synchronous belt assembly.

[0030] See also Figures 4-6As shown in the figure, the adjustment assembly includes a visual detection module 16, an electric slide rail 161, a transverse movement frame 162, a movable pipe 164, a spiral pipe 165, a convex ball 166 and a closing plate 167. Six slotted holes 163 are evenly spaced along the circumference on the electric rotating cylinder 10. The six slotted holes 163 correspond to the six scraping plates 11 respectively. Electric slide rails 161 are symmetrically installed on the left and right sides inside the electric rotating cylinder 10. A transverse movement frame 162 is fixedly connected between the moving parts of the electric slide rails 161 on the left and right sides. The transverse movement frame 162 is slidably connected to the slotted holes 163. Six closing plates 167 are fixedly connected to the transverse movement frame 162 at even intervals.

Convex balls 166 are fixedly connected to the inner sides of the movable pipes 164. The convex balls 166 contact the spiral grooves of the spiral pipes 165. When the convex balls 166 move, the convex balls 166 can drive the spiral pipes 165 to rotate, so that the scraping plates 11 swing for angle adjustment. A visual detection module 16 is installed between the tops of the left sides of the front and rear transverse plates 12. The visual detection module 16 is electrically connected to the electric slide rail 161 through a control module.

[0031] First, the operator externally connects the three feed ends of the four-way valve 6 to an air pump, a container filled with pulp, and a container filled with reagents respectively. The spray pipe 13 is externally connected to the air pump. Then, the reagents and pulp are discharged into the feed pipe 5 through the four-way valve 6. The reagents and pulp in the feed pipe 5 are discharged into the box body 1 and come into contact with the stirring shaft 7 and the porous plate 71. When an appropriate amount of reagents and pulp are discharged into the box body 1, stop discharging the reagents and pulp into the box body 1. When the reagents and pulp come into contact with the liquid level sensor 14, the externally connected air pump can be started to discharge air into the four-way valve 6. The four-way valve 6 discharges the air into the feed pipe 5, and the air in the feed pipe 5 is discharged into the box body 1 to come into contact with the reagents and pulp. At the same time, start the drive motor 73. The drive motor 73 drives the stirring shaft 7 to rotate through the synchronous belt assembly. The rotation of the stirring shaft 7 drives the porous plate 71 to rotate. The rotation of the porous plate 71 stirs the reagents and pulp, enabling the reagents and pulp to fully contact and react. The generated bubbles fully contact and mix with the minerals in the pulp, enabling the minerals to fully adsorb to the bubbles. The bubbles move upward under the agitation of the porous plate 71, and the upward movement of the bubbles drives the minerals to move upward and float on the liquid surface to form a foam layer, thus completing the flotation separation of the minerals. Subsequently, start the liquid level sensor 14. The liquid level sensor 14 detects the liquid level height of the pulp. When the liquid level height of the pulp drops, the liquid level sensor 14 controls the electric lifting frame 15 to start. The electric lifting frame 15 moves downward, driving the cross plate 12 to move downward. The downward movement of the cross plate 12 drives the spray pipe 13 and the visual detection module 16 to move downward. The cross plate 12 also drives the electric rotary cylinder 10 to move downward through the support plate 9. The electric rotary cylinder 10 drives the scraping plate 11 to move downward. At the same time, the cross plate 12 also drives the baffle 3 to move downward. The baffle 3 and the scraping plate 11 move downward synchronously. When the scraping plate 11 and the visual detection module 16 move downward and both come into contact with the foam layer, the bottom of the visual detection module 16 passes through the foam layer and comes into contact with the pulp. The liquid level sensor 14 controls the electric lifting frame 15 to close, and the electric lifting frame 15 stops moving downward. The visual detection module 16 and the scraping plate 11 stop moving downward. At this time, start the visual detection module 16 again. The visual detection module 16 detects the thickness of the foam layer. The visual detection module 16 controls the electric slide rail 161 to start through the control module. The electric slide rail 161 drives the transverse moving frame 162 to move backward. The backward movement of the transverse moving frame 162 drives the movable pipe 164 to move backward. The backward movement of the movable pipe 164 drives the convex ball 166 to move backward. The backward movement of the convex ball 166 drives the spiral pipe 165 to rotate. The rotation of the spiral pipe 165 drives the scraping plate 11 to swing. When the scraping plate 11 swings to contact the bottom of the foam layer, the visual detection module 16 controls the electric slide rail 161 to close. The movable pipe 164 stops driving the spiral pipe 165 to rotate through the convex ball 166, and the scraping plate 11 stops swinging. In this way, it can prevent the position of the scraping plate 11 from exceeding the thickness of the foam layer and scraping off some pulp and mixing it with the scraped minerals again, thus ensuring the effect of scraping the minerals. Then start the reverse rotation of the electric rotary cylinder 10. The reverse rotation of the electric rotary cylinder 10 drives the scraping plate 11 to reverse.When the scraper 11 rotates in reverse and contacts the foam layer, the reverse rotation of the scraper 11 pushes the foam to the right for scraping. The foam and the minerals are separated from the pulp in the box body 1 together. The scraped foam is discharged into the discharge frame 8, and the discharge frame 8 discharges the foam for collection and treatment. At the same time, an external air pump is started to discharge air into the spray pipe 13, and the spray pipe 13 sprays the air to blow the foam layer, so that the foam layer moves to the right and contacts the scraper 11 to be scraped off. Subsequently, the foam and the minerals are screened and separated, and then the minerals are used subsequently. As the foam and the minerals are continuously scraped off, the liquid level height of the pulp in the box body 1 will change, and the liquid level sensor 14 continuously detects the liquid level height, so that the electric lifting frame 15 is started to control the scraper 11 to move up and down and always contact the foam layer, completing the scraping of the foam and the minerals. In this way, the scraper 11 can always contact the foam layer for scraping to complete the collection of the minerals, preventing the scraper 11 from detaching from the foam layer and affecting the scraping, thereby improving the mineral collection effect. When the pulp in the box body 1 completes the flotation separation of the minerals, the external air pump is turned off, the spray pipe 13 stops spraying air, the liquid level sensor 14 and the visual detection module 16 are turned off, and at the same time, the drive motor 73 is turned off, the stirring shaft 7 stops driving the porous plate 71 to rotate, then the electric rotating cylinder 10 is turned off, and the electric rotating cylinder 10 stops driving the scraper 11 to rotate. The electric lifting frame 15 is started to move upward to drive the cross plate 12 to move upward and reset. The cross plate 12 stops driving the spray pipe 13 and the visual detection module 16 to move upward and reset. The cross plate 12 also drives the scraper 11 to move upward and reset through the support plate 9 and the electric rotating cylinder 10. Then, all the pulp in the box body 1 is discharged through the discharge pipe 2.,

[0032] Please refer to Figures 7-10As shown in the figure, the high-efficiency flotation separation device for rare earth ores further includes a screening component installed on the box body 1. The screening component includes a mounting frame 17, a cylinder body 171, a discharge pipe 1701, a filter cylinder 172, a spiral conveyor shaft 173, an air injection pipe 174, an inclined ring 175 and a driving component. A mounting frame 17 is fixedly connected to the lower part of the right outer side of the box body 1. The mounting frame 17 is located below the discharge frame 8. The middle part of the mounting frame 17 is fixedly penetrated with a cylinder body 171. An outlet is opened in the upper right part of the cylinder body 171. The lower right part of the cylinder body 171 is connected with a discharge pipe 1701, and the discharge pipe 1701 can discharge the foam. An inclined ring 175 is fixedly connected to the upper part of the inner side of the cylinder body 171 along the circumferential direction. The inclined ring 175 can guide the minerals. The inclined ring 175 corresponds to the outlet of the cylinder body 171. A filter cylinder 172 is rotatably connected to the inner side of the inclined ring 175 along the circumferential direction. The filter cylinder 172 can filter the minerals in the foam. A spiral conveyor shaft 173 is rotatably penetrated between the middle of the bottom of the filter cylinder 172 and the bottom of the cylinder body 171. The spiral conveyor shaft 173 contacts the inner wall of the filter cylinder 172. When the spiral conveyor shaft 173 rotates, the spiral conveyor shaft 173 can drive the minerals to move upward for conveying. An air injection pipe 174 is connected to the left front side of the cylinder body 171. The air outlet end of the air injection pipe 174 is located above the inclined ring 175. The air injection pipe 174 can eject air to blow the minerals. A driving component is arranged between the spiral conveyor shaft 173 and the filter cylinder 172. When the driving component operates, the driving component can drive the filter cylinder 172 and the spiral conveyor shaft 173 to rotate. The driving component includes a stepping motor 176, a rotating shaft 177, a small gear 178 and a large gear 179. A rotating shaft 177 is rotatably penetrated through the front side of the lower part of the mounting frame 17. Small gears 178 are fixedly sleeved on the middle part of the rotating shaft 177 and the lower part of the outer side of the filter cylinder 172 respectively. Large gears 179 are fixedly sleeved on the top end of the rotating shaft 177 and the lower part of the spiral conveyor shaft 173 respectively. The upper large gear 179 meshes with the upper small gear 178, and the lower large gear 179 meshes with the lower small gear 178. A stepping motor 176 is installed at the bottom of the mounting frame 17. The end of the output shaft of the stepping motor 176 is fixedly connected to the bottom end of the spiral conveyor shaft 173.

[0033] Initially, the jet pipe 174 is externally connected to an air pump, and the collection box is placed below the discharge port of the cylinder body 171. When the scraped foam and minerals are discharged from the discharge frame 8, the foam and minerals fall into the filter cylinder 172. The stepper motor 176 is started, and the stepper motor 176 drives the spiral conveyor shaft 173 to reverse. The reverse rotation of the spiral conveyor shaft 173 drives the lower large gear 179 to reverse. The reverse rotation of the lower large gear 179 drives the lower small gear 178 to rotate forward. The forward rotation of the lower small gear 178 drives the rotating shaft 177 to rotate forward. The forward rotation of the rotating shaft 177 drives the upper large gear 179 to rotate forward. The forward rotation of the upper large gear 179 drives the upper small gear 178 to reverse. The reverse rotation of the upper small gear 178 drives the filter cylinder 172 to reverse. Due to the cooperation of the large gear 179 and the small gear 178, the rotation speeds of the filter cylinder 172 and the spiral conveyor shaft 173 can be made different. The reverse rotation of the filter cylinder 172 drives the foam and minerals to reverse. Through the centrifugal force of the reverse rotation, the foam passes through the filter cylinder 172 and is thrown into the cylinder body 171. The foam in the cylinder body 171 is discharged through the discharge pipe 1701 for collection, while the minerals are filtered in the filter cylinder 172 and contact the spiral conveyor shaft 173. In this way, the separation of the foam and minerals is completed. The reverse rotation of the spiral conveyor shaft 173 drives the minerals to move upward. When the minerals move upward outside the filter cylinder 172, the minerals fall onto the inclined ring 175. At this time, the externally connected air pump is started to discharge air into the jet pipe 174. The jet pipe 174 sprays out the air to blow the minerals on the inclined ring 175, so that the minerals move to the right and are discharged through the discharge port of the cylinder body 171 for collection and treatment. Repeating this process can continuously screen the foam and minerals, separating the foam and minerals. When all the foam and minerals are separated, the stepper motor 176 is turned off. The stepper motor 176 stops driving the spiral conveyor shaft 173 to rotate. The spiral conveyor shaft 173 stops driving the lower large gear 179 to rotate, and the filter cylinder 172 also stops reversing. Then the externally connected air pump is turned off, and the jet pipe 174 stops spraying air. In this way, there is no need for the operator to screen and separate the foam and minerals additionally later, thereby further improving the efficiency of mineral collection.

[0034] Please refer to Figure 1 As shown, the high-efficiency flotation separation device for rare earth ores further includes a transparent scale 18. The transparent scale 18 is fixedly penetrated through the front side of the box body 1, and the transparent scale 18 can indicate the liquid level height in the box body 1.

[0035] When the pulp and the reagent are discharged into the box body 1, the operator can understand the liquid level height in the box body 1 through the transparent scale 18. When the liquid level height reaches the specified height, the discharge of the pulp and the reagent into the box body 1 is stopped. In this way, the liquid level height of the pulp in the box body 1 can be understood in a timely manner, and corresponding treatment can be made according to the liquid level height in a timely manner.

[0036] Finally, it is necessary to state that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the protection scope of the present invention; any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention shall fall within the scope of protection required by the present invention.
