The closing plate 167 can block the slurry to prevent it from entering the electric rotating drum 10. The shafts of the six scrapers 11 are fixedly fitted with spiral tubes 165. The six ends of the transverse frame 162 are fixedly connected to movable tubes 164. The movable tubes 164 are slidably fitted on the outside of the spiral tubes 165. A convex ball 166 is fixed to the inside of the movable tube 164. The convex ball 166 contacts the spiral groove of the spiral tube 165. When the convex ball 166 moves, the convex ball 166 can drive the spiral tube 165 to rotate, so that the scraper 11 swings to adjust the angle. A visual detection module 16 is installed between the top 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.

[0033] First, the operator connects the three feed ends of the four-way valve 6 to an air pump, a container filled with slurry, and a container filled with reagents, and connects the nozzle 13 to the air pump, and then discharges the reagents and slurry into the feed pipe 5 through the four-way valve 6. The reagents and slurry in the feed pipe 5 are discharged into the box body 1 and contact the stirring shaft 7 and the porous plate 71. When an appropriate amount of reagents and slurry are discharged into the box body 1, stop discharging the reagents and slurry into the box body 1. The reagents and slurry contact the liquid level sensor 14, and then start the external air pump to discharge air into the four-way valve 6. The four-way valve 6 discharges air into the feed pipe 5. The air in the feed pipe 5 is discharged into the box body 1 and contacts the reagents and slurry. 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 stirring shaft 7 The rotation drives the porous plate 71 to rotate, and the rotation of the porous plate 71 stirs the reagent and the slurry, so that the reagent and the slurry are fully contacted and reacted, and the bubbles generated are fully contacted and mixed with the minerals in the slurry, so that the minerals and the bubbles are fully adsorbed, and the bubbles move upward under the stirring 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, and then the liquid level sensor 14 is started, and the liquid level sensor 14 detects the liquid level of the slurry. When the liquid level of the slurry drops, the liquid level sensor 14 controls the electric lifting frame 15 to start through the control module, and the electric lifting frame 15 moves downward to drive the horizontal plate 12 to move downward, and the horizontal plate 12 moves downward to drive the nozzle 13 and the visual detection module 16 to move downward, and the horizontal plate 12 moves downward to drive the nozzle 13 and the visual detection module 16 to move downward. The plate 12 also drives the electric rotating drum 10 to move downward through the support plate 9, and the electric rotating drum 10 drives the scraper 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 scraper 11 move downward synchronously. When the scraper 11 and the visual inspection module 16 move downward and contact the foam layer, the bottom of the visual inspection module 16 passes through the foam layer and contacts the slurry. The liquid level sensor 14 controls the electric lifting frame 15 to close, and the electric lifting frame 15 stops moving downward. The visual inspection module 16 and the scraper 11 stop moving downward. At this time, the visual inspection module 16 is started again. The visual inspection module 16 detects the thickness of the foam layer. The visual inspection module 16 controls the electric slide 161 through the control module to start, and the electric slide 161 drives the transverse frame 16 2 moves backward, the transverse frame 162 moves backward and drives the movable tube 164 to move backward, the movable tube 164 moves backward and drives the convex ball 166 to move backward, the convex ball 166 moves backward and drives the spiral tube 165 to rotate, the rotation of the spiral tube 165 drives the scraper 11 to swing, and when the scraper 11 swings to contact the bottom of the foam layer, the visual inspection module 16 controls the electric slide 161 to close, the movable tube 164 stops driving the spiral tube 165 to rotate through the convex ball 166, and the scraper 11 stops swinging, so as to prevent the position of the scraper 11 from exceeding the thickness of the foam layer and scraping part of the slurry together and mixing it with the scraped mineral again, thereby ensuring the effect of mineral scraping, and then start the electric rotating drum 10 to reverse, and the electric rotating drum 10 reverses and drives the scraper 11 to reverse,The scraper 11 is rotated to push the foam to the right for scraping, and the foam and the mineral are separated from the slurry in the box 1. The scraped foam is discharged into the discharge frame 8, and the discharge frame 8 discharges the foam for collection and processing. At the same time, the external air pump is started to discharge air into the nozzle 13. The nozzle 13 sprays air to blow the foam layer, causing the foam layer to move to the right and contact the scraper 11 to be scraped, and then the foam and the mineral are screened and separated, and the mineral is used subsequently. As the foam and minerals are continuously scraped, the liquid level of the slurry in the box 1 will change, and the liquid level sensor 14 will continuously detect the liquid level, so that the electric lifting frame 15 starts to control the scraper 11 to move up and down and contact the foam layer to complete the scraping of the foam and the mineral. In this way, the scraper 11 can always contact the foam layer to scrape and complete the collection of the minerals, so as to prevent the scraper 11 from separating from the foam layer and affecting the scraping, thereby improving the mineral collection effect. When the slurry in the box 1 completes the flotation separation of the minerals, the external air pump is turned off, the nozzle 13 stops spraying air, the liquid level sensor 14 and the visual inspection module 16 are turned off, and the drive motor 73 is turned off at the same time. The stirring shaft 7 stops driving the porous plate 71 to rotate, and the electric rotating drum 10 is then turned off. The electric rotating drum 10 stops driving the scraper 11 to rotate, and the electric lifting frame 15 is started to move upward and drive the cross plate 12 to move upward and reset. The cross plate 12 stops driving the nozzle 13 and the visual inspection module 16 to move upward and reset. The cross plate 12 also drives the scraper 11 upward and reset through the support plate 9 and the electric rotating drum 10. Then, all the slurry in the box 1 is discharged through the discharge pipe 2.

[0034] See also Figure 7-10As shown, the rare earth ore efficient flotation separation device also includes a screening assembly installed on the box body 1, the screening assembly includes a mounting frame 17, a cylinder 171, a discharge pipe 1701, a filter cylinder 172, a spiral conveying shaft 173, an air injection pipe 174, an oblique ring 175 and a drive assembly. The mounting frame 17 is fixedly connected to the lower right side of the outer side of the box body 1. The mounting frame 17 is located below the discharge frame 8. The middle of the mounting frame 17 is fixedly connected with the cylinder 171. The upper right side of the cylinder 171 is provided with a discharge port. The lower right side of the cylinder 171 is connected to the discharge pipe 170 1. The discharge pipe 1701 can discharge the foam. The upper inner part of the cylinder 171 is fixed with an oblique ring 175 along the circumferential direction. The oblique ring 175 can guide the minerals. The oblique ring 175 corresponds to the discharge port of the cylinder 171. The inner side of the oblique ring 175 is connected with a filter cartridge 172 along the circumferential direction. The filter cartridge 172 can filter the minerals in the foam. The middle of the bottom of the filter cartridge 172 and the bottom of the cylinder 171 are rotatably connected with a screw conveying shaft 173. The screw conveying shaft 173 contacts the inner wall of the filter cartridge 172. When the screw conveying shaft 173 is in contact with the inner wall of the filter cartridge 172, the filter cartridge 172 is opened. When the screw conveying shaft 173 rotates, the minerals can be driven to move upward for transportation. The left front side of the cylinder 171 is connected to the air jet 174. The air outlet end of the air jet 174 is located above the bevel ring 175. The air jet 174 can spray air to blow the minerals. A driving assembly is provided between the screw conveying shaft 173 and the filter cylinder 172. When the driving assembly is in operation, the driving assembly can drive the filter cylinder 172 and the screw conveying shaft 173 to rotate. The driving assembly includes a stepping motor 176, a rotating shaft 177, a small gear 178 and a large gear. Gear 179, a rotating shaft 177 is rotatably connected to the front side of the lower part of the mounting frame 17, a small gear 178 is fixedly mounted on the middle part of the rotating shaft 177 and the lower part of the outer side of the filter cartridge 172, a large gear 179 is fixedly mounted on the top of the rotating shaft 177 and the lower part of the spiral conveying shaft 173, the upper large gear 179 is engaged with the upper small gear 178, and the lower large gear 179 is engaged with the lower small gear 178, a stepper motor 176 is installed at the bottom of the mounting frame 17, and the output shaft end of the stepper motor 176 is fixedly connected to the bottom end of the spiral conveying shaft 173.

[0035] Initially, the air injection pipe 174 is connected to an external air pump, and the collection frame is placed below the discharge port of the cylinder 171. When the scraped foam and minerals are discharged from the discharge frame 8, the foam and minerals fall into the filter cylinder 172, and the stepper motor 176 is started. The stepper motor 176 drives the screw conveying shaft 173 to reverse, and the screw conveying shaft 173 reverses to drive the lower large gear 179 to reverse, and the lower large gear 179 reverses to drive the lower small gear 178 to rotate forward, and the lower small gear 178 rotates forward to drive the rotating shaft 177 to rotate forward, and the rotating shaft 177 rotates forward to drive the upper large gear 179 to rotate forward, and the upper large gear 179 rotates forward to drive the upper small gear 178 to reverse, and the upper small gear 178 reverses to drive the filter cylinder 172 to reverse. Due to the cooperation between the large gear 179 and the small gear 178, the rotation speeds of the filter cylinder 172 and the screw conveying shaft 173 can be kept constant. At the same time, the filter cartridge 172 reverses and drives the foam and the mineral to reverse. Through the centrifugal force of the reverse rotation, the foam passes through the filter cartridge 172 and is thrown into the cylinder 171. The foam in the cylinder 171 is discharged through the discharge pipe 1701 for collection, and the mineral is filtered in the filter cartridge 172 and contacts the screw conveying shaft 173. In this way, the separation of the foam and the mineral is completed. The screw conveying shaft 173 reverses and drives the mineral to move upward. When the mineral moves upward to the outside of the filter cartridge 172, the mineral falls onto the oblique ring 175. At this time, the external air pump is started to discharge air into the jet pipe 174. The jet pipe 174 sprays air to blow the mineral on the oblique ring 175, causing the mineral to move to the right and be discharged through the discharge port of the cylinder 171 for collection and processing. This is repeated to continuously screen the foam and the mineral, so that the foam and the mineral are separated. When all the foam and minerals are separated, stepper motor 176 is turned off, which stops driving screw conveyor shaft 173, which in turn stops driving large gear 179 below. Filter cartridge 172 also stops rotating, and the external air pump is turned off, stopping air from air jet 174. This eliminates the need for operators to perform additional screening and separation of the foam and minerals, further improving mineral collection efficiency.

[0036] See also Figure 1 As shown, the rare earth ore efficient flotation separation device further includes a transparent scale 18 , which is fixedly connected to the front side of the box body 1 and can indicate the liquid level in the box body 1 .

[0037] When the slurry and reagent are discharged into the box body 1, the operator can understand the liquid level in the box body 1 through the transparent scale 18. When the liquid level reaches a specified height, the operator stops discharging the slurry and reagent into the box body 1. In this way, the slurry level in the box body 1 can be understood in a timely manner, so that corresponding treatment can be made in a timely manner according to the liquid level.
