[0020] The driving mechanism 16 includes vertical rod 161 connected with the inner wall of the cylinder 15, the upper half of the side wall of the barrel body 1 is provided with protruding block 162 for the vertical rod 161 to pass through, the top end of the vertical rod 161 penetrates the side wall of the cover plate 2 and is fixed with handle, the vertical rod 161 on both sides of the cover plate 2 is provided with electromagnet block 163, the electromagnet block 163 is located above the protruding block 162, wherein the upper electromagnet block 163 abuts against the top end surface of the cover plate 2, and the spacing between the lower electromagnet block 163 and the bottom of the cover plate 2 is greater than the opening width of the arch part 8.

[0021] The connecting mechanism 12 includes screw rod I 121 provided on the inner side wall of the annular seat 11 and screw rod II 122 provided at the corresponding end of the stirring paddle 6, wherein the corresponding screw rod I 121 and screw rod II 122 are connected through screw pipe 123, and the length of the screw pipe 123 is not greater than the length of the screw rod II 122.​

[0022] As shown in Figure 2 The top wall of the arch part 8 is provided with a ring of mounting openings 17 for accommodating the top end of the filter screen 10, and the inner bottom wall of the arch part 8 is provided with a ring of clamping grooves 18 for fixing the bottom end of the filter screen 10.

[0023] The method of using the present application is as follows: first, the rare earth raw materials and the solution are added into the barrel 1 through the feeding pipe 3, and then the motor 4 is started to drive the rotating shaft 5 and the stirring paddle 6 to rotate, thereby stirring the rare earth raw materials in the barrel 1 to speed up the dissolution efficiency and effect of the rare earth raw materials. When the stirring paddle 6 rotates, the annular seat 11 is driven to rotate below the cylinder 15 and in the opening of the arch part 8 through the connecting mechanism 12. The annular seat 11 drives the scraper 14 to rotate in the opening of the arch part 8 and to scrape and clean the inner side wall of the filter screen 10 through the connecting block 13. At this time, the upper electromagnet block 163 is energized to magnetically connect and fix the cover plate 2, thereby fixing the position of the vertical rod 161, preventing the cylinder 15 from moving up and down, and sealing the opening of the arch part 8 through the annular seat 11 and the cylinder 15 when the barrel 1 is dissolving, preventing a large amount of large-particle materials from entering the opening of the arch part 8 and contacting the filter screen 10 to block it.

[0024] When the dissolution is completed, the water outlet pipe 9 is opened, and the upper electromagnet block 163 is de-energized, and the lower electromagnet block 163 is energized to pull and lift the vertical rod 161 upward, so that the cylinder 15 moves upward to the position above the opening of the arch part 8 to be suspended. At this time, the lower electromagnet block 163 contacts and magnetically connects with the bottom end of the cover plate 2 to prevent the cylinder 15 from moving downward, so that the liquid in the barrel 1 can flow into the opening of the arch part 8 and be filtered by the filter screen 10. At this time, the annular filter screen 10 can effectively increase the filtering area and can filter the solution faster. The filtered liquid is discharged through the water outlet pipe 9 to other containers or equipment. The rotating stirring paddle 6 can continue to rotate through the connecting mechanism 12 to drive the annular seat 11. At this time, the annular seat 11 drives the scraper 14 to rotate on the inner side wall of the filter screen 10 through the connecting block 13 to scrape and clean the particles and other impurities that may adhere to the inner wall, thereby preventing the filter screen 10 from being blocked by the adhered impurities in the inner side wall through forced cleaning. The final filtered impurities and a small amount of residual liquid can be discharged through the discharge pipe 7. When the work is completed, the bolts can be removed according to the requirements to pull out the filter screen 10 from the mounting opening 17 and the opening of the arch part 8 through the annular plate 19, thereby thoroughly cleaning or replacing the filter screen 10.

[0025] The above has carried out the detailed explanation to the application, but the content described is only the preferred embodiment of the application, cannot be considered for limiting the implementation scope of the application. Any equivalent change and improvement made according to the scope of the application shall still belong to the patent coverage of the application.
