Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing, in particular to a leaching device for rare earth metal processing. Background Technique

[0002] Rare earth is the general term for seventeen metal elements including lanthanide elements, scandium and yttrium in the chemical periodic table. Leaching is to add solid materials (such as ores, concentrates, fused sands or other semi-finished products) into a liquid solvent, so that one or several valuable metals in the solid materials dissolve in the liquid solvent, in order to extract valuable metals from the solution in the next step. However, when leaching rare earth metals, there will be residues of slag, so filter plates are used to separate the slag and the leaching solution. However, most of the filter plates in the leaching devices are static mesh structures, resulting in the remaining slag being easily stuck in the grids, and the stuck slag will affect the filtration of the leaching solution by the filter plate, thereby reducing the quality of rare earth metal leaching.

[0003] For example, the existing Chinese publication number is: CN208594322U, a leaching device for rare earth metal processing, which: "includes a support rod, a leaching barrel, a distillation barrel and a cover plate. The top of the support rod is provided with a support plate, and a motor is installed on the upper end of the support plate. A connecting rod is provided at the end of the motor, and a stirring rod is installed on the side of the connecting rod. The leaching barrel is arranged inside the support rod."

[0004] It can be seen that the cited patent document has the problem that the residual slag is easy to block the filter plate. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a leaching device for rare earth metal processing to solve the problems raised in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A leaching device for rare earth metal processing, including a leaching box. The inner side wall of the leaching box is inclined and provided with a filter plate for filtering slag and leaching solution. Limiting components for limiting the filter plate are provided on both inner side walls of the leaching box and both side surfaces of the filter plate. An arc-shaped block is installed on the surface of the filter plate. A driving motor is installed on the top surface of the leaching box. The output end of the driving motor penetrates the leaching box and is connected with a rotating shaft. The lower half of the circumference of the rotating shaft is rotatably connected with a pressing ball through a bracket. A plurality of vertical rods are equidistantly installed on the bottom surface of the filter plate. A plurality of bottom boxes for the vertical rods to enter are equidistantly installed on the inner bottom surface of the leaching box. The inner bottom surface of each bottom box is connected with a spring. The bottom surface of each vertical rod respectively enters the inner cavity of each bottom box and is connected with the free end of the spring.

[0007] Preferably, the limiting component includes a groove, a vertical block and a limiting plate. There are two grooves which are respectively arranged on both inner side walls of the leaching box.

[0008] Preferably, a plurality of vertical blocks are provided and are respectively fixed on the inner bottom surfaces of the two grooves, and two limiting plates are provided and are respectively connected to the two side surfaces of the filter plate.

[0009] Preferably, a plurality of through grooves are respectively formed on the top surfaces of the two limiting plates and are slidably adapted to the plurality of vertical blocks.

[0010] Preferably, vertical rods are symmetrically and longitudinally installed on the inner bottom surface of each bottom box, and sliders slidably adapted to the vertical rods are respectively installed on the two side surfaces of the inner cavity of each bottom box where the vertical rods are located.

[0011] Preferably, a plurality of mixing rods for mixing rare earth metals and leaching solution are equidistantly installed on the circumferential side of the rotating shaft.

[0012] Preferably, a drain pipe for discharging the leaching solution is communicated with the inner bottom surface of the leaching tank, and a slag discharge pipe for discharging residual slag is communicated with one side surface of the leaching tank.

[0013] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0014] For the leaching device for rare earth metal processing, through the settings of the arc-shaped block and the pressing ball, the driving motor and the rotating shaft can drive the pressing ball to filter and press the arc-shaped block, thereby driving the filter plate to move downward, and cooperating with the spring and the circular motion of the rotating shaft driving the pressing ball, the filter plate can perform longitudinal reciprocating motion to achieve the vibration effect. Compared with the existing device that uses a static filter plate to filter the slag and leaching solution, this device can make the filter plate vibrate, reduce the situation that the residual slag blocks the filter holes, and improve the filtering efficiency of the leaching solution and slag.

[0015] Through the setting of the limiting component, the longitudinal reciprocating motion of the filter plate can be limited. Through the settings of the vertical rod and the slider, the longitudinal movement of the vertical rod can be limited. And through the setting of the mixing rod, the chemical reaction between the leaching solution and the rare earth metal can be improved. Through the settings of the drain pipe and the slag discharge pipe, the filtered leaching solution and slag can be discharged from the box body for subsequent processing operations.

Detailed implementation manners

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0024] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the figures shown by the present utility model, and are hereby explained together.

[0025] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., according to actual needs.

[0026] As Figures 1 to 4 Shown, a leaching device for rare earth metal processing includes a leaching tank 1. The top surface of the leaching tank 1 is symmetrically provided with feed inlets 18, which can put the rare earth metals to be leached into the leaching tank 1, and at the same time put the leaching solution into the leaching tank 1 to allow a chemical reaction between the leaching solution and the rare earth metals.

[0027] A driving motor 4 is installed on the top surface of the leaching tank 1. The output end of the driving motor 4 penetrates through the leaching tank 1 and is connected with a rotating shaft 5. A plurality of mixing rods 10 for mixing rare earth metals and the leaching solution are equidistantly installed on the periphery of the rotating shaft 5. The rotation of the mixing rods 10 can allow a uniform chemical reaction between the leaching solution and the rare earth metals.

[0028] The inner side wall of the leaching tank 1 is inclined and provided with a filter plate 2 for filtering slag and leaching solution. An arc-shaped block 3 is installed on the surface of the filter plate 2. The lower half of the circumference of the rotating shaft 5 is rotationally connected with a pressure ball 6 through a bracket. When the driving motor 4 drives the rotating shaft 5 to rotate, the rotating shaft 5 will drive the pressure ball 6 to do circular motion through the bracket, so that the pressure ball 6 can move to one side of the arc-shaped block 3 and move along the top surface of the arc-shaped block 3, and then the pressure ball 6 can press the arc-shaped block 3 downward, so that the arc-shaped block 3 can drive the filter plate 2 to move downward. A plurality of vertical rods 7 are equidistantly installed on the bottom surface of the filter plate 2, and a plurality of bottom boxes 8 for the vertical rods 7 to enter are equidistantly installed on the inner bottom surface of the leaching tank 1. The inner bottom surface of each bottom box 8 is connected with a spring 9. The bottom surfaces of each vertical rod 7 respectively enter the inner cavity of each bottom box 8 and are connected with the free ends of the springs 9. After the filter plate 2 moves downward, it will squeeze a plurality of springs 9 through a plurality of vertical rods 7. After the pressure ball 6 cancels the extrusion of the arc-shaped block 3, the vertical rods 7 can be driven to move through the rebound of the springs 9, so that the filter plate 2 can move upward. By repeating the operation, the pressure ball 6 can regularly squeeze the arc-shaped block 3, and cooperate with the spring 9, so that the filter plate 2 can continuously perform longitudinal reciprocating motion, so as to achieve the effect of vibrating the filter plate 2, so that the filter plate 2 can filter the slag remaining on the surface, avoiding the problem that the remaining slag will block the filter holes of the filter plate 2 and affect the filtration of the leaching solution by the filter plate 2, and improving the quality of rare earth metal leaching.

[0029] Limiting components for limiting the filter plate 2 are provided on both inner side walls of the leaching tank 1 and both side surfaces of the filter plate 2. The limiting components include grooves 11, vertical blocks 12 and limiting plates 13. There are two grooves 11 which are respectively arranged on both inner side walls of the leaching tank 1. A plurality of vertical blocks 12 are respectively fixed on the inner bottom surfaces of the two grooves 11. There are two limiting plates 13 which are respectively connected to both side surfaces of the filter plate 2. A plurality of through grooves are respectively formed on the top surfaces of the two limiting plates 13 and are slidably matched with the plurality of vertical blocks 12. When the pressure ball 6 and the spring 9 cooperate to make the filter plate 2 perform longitudinal reciprocating motion, the filter plate 2 will drive the limiting plate 13 to perform longitudinal reciprocating motion in the inner cavity of the groove 11, and at the same time make the plurality of through grooves perform longitudinal reciprocating motion around the vertical blocks 12, so as to limit the longitudinal reciprocating motion of the filter plate 2.

[0030] Vertical rods 14 are symmetrically and longitudinally installed on the inner bottom surface of each bottom box 8. Sliders 15 slidably matched with the vertical rods 14 are respectively installed on both side surfaces of each vertical rod 7 located in the inner cavity of the bottom box 8. When the vertical rod 7 performs longitudinal reciprocating motion in the inner cavity of the bottom box 8, the vertical rod 7 will drive the vertical rod 14 to perform longitudinal reciprocating motion around the slider 15 to limit the vertical rod 7.

[0031] The inner bottom surface of the leaching tank 1 is connected with a drain pipe 16 for discharging the leaching solution, and the free end of the drain pipe 16 is externally connected to a distillation tank (not shown). The leaching solution separated by the filter plate 2 can pass through the filter plate 2 and fall into the drain pipe 16, and then be transported from the drain pipe 16 to the externally connected distillation tank for the next processing step. One side surface of the leaching tank 1 is connected with a slag discharge pipe 17 for discharging the residual slag, and the slag discharge pipe 17 is arranged at the lower end of the filter plate 2. Therefore, the slag isolated by the filter plate 2 will be discharged from the leaching tank 1 along the slag discharge pipe 17. Cooperating with the briquetting ball 6 and the spring 9, the filter plate 2 can be vibrated to improve the filtering effect on the slag.

[0032] Working principle:

[0033] For the leaching device for rare earth metal processing, the rare earth metal to be leached is put into the leaching tank 1 through the feed inlet 18. At the same time, the leaching solution is put into the leaching tank 1, and the driving motor 4 is started. The driving motor 4 drives the mixing rod 10 to rotate through the rotating shaft 5, improving the chemical reaction between the rare earth metal and the leaching solution. When the rotating shaft 5 rotates, it will drive the briquetting ball 6 to do circular motion through the bracket at the same time, so that the briquetting ball 6 can regularly squeeze the arc-shaped block 3, enabling the arc-shaped block 3 to drive the filter plate 2 to move downward, and at the same time squeezing the spring 9. After the briquetting ball 6 moves to one side, the filter plate 2 can be driven to return by the rebound of the spring 9. By repeating the operation, the filter plate 2 can continuously perform longitudinal reciprocating motion to achieve the vibration effect of the filter plate 2, so that the filter plate 2 can filter the slag remaining on the surface. The leaching solution passing through the filter plate 2 will be transported to the externally connected distillation tank along the drain pipe 16, and the remaining slag will be discharged along the slag discharge pipe 17, avoiding the problem that the remaining slag will block the filter holes of the filter plate 2 and affect the filtration of the leaching solution by the filter plate 2, and improving the quality of rare earth metal leaching.
