Description

Technical Field

[0001] The invention relates to the technical field of rare earth extraction, and in particular to rare earth extraction equipment for rare earth processing. Background Art

[0002] Rare earth extraction is the process of extracting and separating rare earth elements from ores or solutions. Its principle is based on the difference in the distribution of different rare earth elements between two immiscible liquids, and uses organic solvents to selectively extract rare earth ions from the aqueous phase.

[0003] Traditional rare earth extraction equipment usually involves placing a rare earth-containing aqueous solution and an extractant in the same container, stirring to achieve full mixing of the two, and then standing to allow the two phases to separate, thereby completing the extraction of rare earth elements. However, this traditional extraction method has the following problems: 1. Since the stirring, mixing and standing of the rare earth aqueous solution and the extractant are all carried out in the same container, and each batch of solution requires a long standing time, when one batch of solution is standing, the container cannot be immediately used for stirring and mixing the next batch of solution, resulting in low extraction efficiency; 2. When the two liquids in the container are completely separated, the lower liquid is usually discharged first through the drain pipe. During the drainage process, a vortex may occur due to reasons such as too fast drainage speed, which may draw in the upper liquid, resulting in the two liquids being unable to be separated well.

In order to discharge the two types of liquids in the liquid storage tank 5 respectively, the inner wall of the liquid storage tank 5 is symmetrically connected with two connecting rods 25, and a guide tube 26 is connected between the two connecting rods 25. The guide tube 26 is located at the center of the liquid storage tank 5. The lifting plate 27 is slidably connected to the outer wall of the guide tube 26 and can slide up and down. The water bag 28 is connected to the outer side of the lifting plate 27. The water bag 28 is annular in shape, and the water bag 28 and the lifting plate 27 are circumferentially spaced and symmetrically connected with a telescopic connecting rod 2801. The telescopic connecting rod 2801 can be adaptively extended and retracted with the expansion and contraction of the water bag 28. The telescopic connecting rod 2801 can horizontally limit the top and bottom surfaces of the water bag 28 to ensure that the water bag 28 can expand in the horizontal direction.

The bag 28 is expanded and contracted, and the lifting component is used to control the lifting plate 27 and the water bag 28 to lift; the control component includes a waterproof breathable membrane 30, a water pump 31, a water pumping pipe 32, a camera 33 and a lamp 34. A water storage chamber 29 is opened on the lower side of the liquid storage tank 5, and a through hole is also opened on the side of the liquid storage tank 5 so that the water storage chamber 29 can be connected with the outside through the through hole, and the waterproof breathable membrane 30 is arranged in the through hole so that the outside air can enter the water storage chamber 29 through the through hole, while the water in the water storage chamber 29 cannot be discharged outward through the through hole, thereby preventing the water in the water storage chamber 29 from leaking due to the tilt of the liquid storage tank 5. The water pump 31 is connected to the bottom surface of the lifting plate 27, and the water pump 31 is connected to the water bag 28. The two ends of the water pumping pipe 32 are respectively connected to The water pump 31 and the water storage chamber 29, the water suction pipe 32 is a hose, the camera 33 and the lamp 34 are both connected to the top surface of the lifting plate 27, and the camera 33 and the lamp 34 are arranged opposite to each other; the lifting assembly includes a driving motor III 35, a screw 36 and a circular magnet 3601, the driving motor III 35 is connected to the lower side of the inner part of the guide tube 26, the screw 36 is connected to the output shaft of the driving motor III 35, and the upper end of the screw 36 is rotatably connected to the guide tube 26, the circular magnet 3601 is slidably connected to the inner wall of the guide tube 26, and the circular magnet 3601 is threadedly connected to the screw 36, the lifting plate 27 is made of iron, and the magnetic force of the circular magnet 3601 can adsorb the lifting plate 27 through the guide tube 26 to drive the lifting plate 27 to rise and fall synchronously.

[0034] Initially, a certain amount of water is contained in the water storage chamber 29, the control valve 10 is in a closed state, and one of the liquid storage tanks 5 is located directly below the lower end of the stirring tank 9, and the circular magnet 3601 is located at the lower end of the screw 36; first, a proper amount of rare earth aqueous solution is put into the stirring tank 9 through the liquid filling port, and then the feeding pump 18 is controlled by the control panel 601 to intermittently extract the extractant, and the extractant is intermittently fed into the rotating tube 16 through the feeding pipe 19 and the hollow ring 20. The extractant in the rotating tube 16 will flow out into the stirring tank 9 through the through hole 1701 of the stirring blade 17. At the same time, the driving motor II 15 can be controlled by the control panel 601 to drive the rotating tube 16 and the stirring blade 17 to rotate. The rotation of the stirring blade 17 can not only evenly transport the extractant to various areas in the stirring tank 9, but also fully stir and mix the rare earth aqueous solution and the extractant in the stirring tank 9. And the intermittent addition of the extractant can ensure the best extraction effect; then open the control valve 10, the mixed solution in the stirring tank 9 will fall down into one of the liquid storage tanks 5 due to gravity, and then close the control valve 10. At this time, the mixed solution can be left to stand in one of the liquid storage tanks 5, and the next batch of solutions can be stirred and mixed in the stirring tank 9, thereby improving work efficiency; then control the driving motor Ⅰ11 through the control panel 601 to drive the connecting gear 12 to rotate, so that the connecting gear 12 can rotate around the outer side of the fixed gear ring 13, thereby driving the rotating frame 3 and the liquid storage tank 5 to rotate, so that the next liquid storage tank 5 can rotate to the bottom of the lower end of the stirring tank 9, so as to receive the next batch of mixed solution; when the liquid storage tank 5 containing the mixed solution rotates to the bottom of the rotating cover plate 8, the rotating cover plate 8 can be manually rotated upward to open, so as to facilitate manual observation of the standing condition of the mixed solution;When the mixed solution is completely separated, the corresponding lamp 34 and camera 33 can be controlled to start working through the control panel 601. The lamp 34 can illuminate the inside of the corresponding liquid storage tank 5, so that the camera 33 can shoot the color of the liquid inside the liquid storage tank 5, and the camera 33 can upload the shooting picture to the control panel 601 for display (the initial shooting picture of the camera 33 is the color of the lower layer of liquid in the liquid storage tank 5). Then, the corresponding drive motor III 35 is controlled through the control panel 601 to drive the screw 36 to rotate, driving the circular magnet 3601 to move upward. The circular magnet 3601 can drive the lifting plate 27 to move upward through magnetic force. The lifting plate 27 can drive the water bag 28, the camera 33 and the lamp 34 to move upward. When the camera When the head 33 and the lamp 34 move upward and pass through the boundary line between the two layers of liquid, the camera 33 captures the color of the upper layer of liquid in the liquid storage tank 5. At this time, the color of the display screen at the control panel 601 will change, and then the corresponding drive motor III 35 can be controlled to stop working through the control panel 601. At the same time, the control panel 601 can control the corresponding water pump 31 to start working. The water pump 31 can extract water from the water storage chamber 29 through the pumping pipe 32 and transport the water to the water bag 28. Under the limiting action of the telescopic connecting rod 2801, the water bag 28 can be horizontally expanded, and the telescopic connecting rod 2801 can be extended, so that the two liquids in the liquid storage tank 5 can be separated by the expanded water bag 28. It is located slightly below the dividing line of the two layers of liquid, so it can ensure that the lower layer of liquid in the liquid storage tank 5 (liquid containing rare earth ions) is pure enough, and a small amount of the lower layer of liquid will be mixed into the upper layer of liquid in the liquid storage tank 5, which can be recycled later. Then, the docking pipe I 23 and the docking pipe II 24 are connected to the drain pipe I 21 and the drain pipe II 22 respectively, and then the valves on the drain pipe I 21 and the drain pipe II 22 are opened, so that the two liquids in the liquid storage tank 5 can be discharged separately, which is convenient for manual collection of the two liquids. In this way, the phenomenon of simultaneous discharge of the two liquids can be prevented during the discharge process. After the two liquids in the liquid storage tank 5 are completely discharged, the corresponding lamps 34 and cameras can be controlled through the control panel 601 The head 33 stops working, and the control panel 601 can control the corresponding water pump 31 to extract the water in the water bag 28, so that the water bag 28 shrinks, the telescopic connecting rod 2801 shortens, and the water can be transported back to the water storage chamber 29 through the water pumping pipe 32. At the same time, the control panel 601 can control the corresponding drive motor III 35 to drive the screw 36 to reverse, drive the circular magnet 3601 to move downward and reset, and the circular magnet 3601 can drive the lifting plate 27 to move downward and reset through magnetic force. The lifting plate 27 can drive the water bag 28, the camera 33 and the lamp 34 to move downward and reset; under the sliding action of the slide plate 4, the liquid storage tank 5 containing the mixed solution can also be manually taken out from the rotating frame 3, and a new liquid storage tank 5 can be replaced and placed on the rotating frame 3 for use. ;

The friction between the rubber blocks 39 and the liquid storage tank 5 can Limiting is performed to prevent the liquid storage tank 5 from moving and deviating during the rotation process. When the liquid storage tank 5 containing the mixed solution needs to be taken out manually, the rubber block 39 can be driven by the corresponding electric push rod Ⅰ38 to move away from the liquid storage tank 5, so that the rubber block 39 is separated from the liquid storage tank 5. Then the liquid storage tank 5 can be replaced, and then the rubber block 39 can be driven by the corresponding electric push rod Ⅰ38 to move towards the liquid storage tank 5, so that the rubber block 39 contacts with the liquid storage tank 5, thereby limiting the position of the new liquid storage tank 5.

[0036] like Figure 8 and Fig. 9 As shown, it also includes a connecting block 40, an electric push rod II 41, a mounting ring 42, a vertical pipe 43, an annular nozzle 44, a scraper rod 45 and a scraper ring 46.

[0037] As the use time increases, it is inevitable that a small amount of rare earth ions and extractants will adhere to the inner wall of the stirring tank 9; at this time, the rare earth aqueous solution and the extractant are no longer injected into the stirring tank 9, and then the upper end of the vertical pipe 43 can be connected to an external water source, so that water can be transported to the annular nozzle 44 through the vertical pipe 43 and sprayed out, and at the same time, the installation ring 42 can be driven downward by the electric push rod II 41, and the installation ring 42 can drive the vertical pipe 43 and the annular nozzle 44 to move downward, and the annular nozzle 44 can spray water to wash the inner wall of the stirring tank 9 in all directions; at the same time At the same time, the mounting ring 42 can drive the scraper ring 46 to move downward, and the scraper ring 46 can scrape down the material adhering to the inner wall of the mixing tank 9.

The placement block 47 is connected to the right side of the top surface of the base plate 1, the placement block 47 is located on the right side of the fixing seat 2, and a transverse groove 4701 is opened on the placement block 47, a guide rod (not shown in the figure) is arranged in the transverse groove 4701, the screw motor 48 is connected to the right side of the top surface of the base plate 1, the screw motor 48 is located on the right side of the placement block 47, and an electromagnet 49 is slidably connected to the guide rod in the transverse groove 4701. The electromagnet 49 can slide left and right on the guide rod in the transverse groove 4701, and the electromagnet 49 is threadedly connected to the screw of the screw motor 48. The width of the electromagnet 49 is the same as that of the slide plate 4. The width is slightly smaller than the width of the transverse groove 4701; since the liquid storage tank 5 is heavy, when the liquid storage tank 5 needs to be taken out manually for cleaning or replacement, the electromagnet 49 can be driven to move to the left by the screw motor 48, so that the electromagnet 49 contacts one of the slides 4, and then the electromagnet 49 is energized to attract the slide 4 through magnetic force, and then the electromagnet 49 is driven to move to the right by the screw motor 48, which can pull the corresponding slide 4 and the liquid storage tank 5 to move to the right, so that the slide 4 can slide into the transverse groove 4701 to limit the liquid storage tank 5 containing the mixed solution, thereby assisting the manual removal of the liquid storage tank 5, saving time and effort.
