When sliding into the pickling barrel 402, a diluted inorganic acid solution is added to the barrel, and then the third motor 405 is started. When the output shaft of the third motor 405 rotates, the stirring shaft 404 is driven to rotate, and the stirring shaft 404 drives the mounting sleeve 406 to rotate. When the mounting sleeve 406 rotates, it drives the stirring rod 407 to rotate, so that the material and the inorganic acid solution are stirred. , the rare earth elements in the electronic waste particles are converted into easily soluble rare metal salt solutions by acid dissolution, thereby realizing the extraction of rare earth materials from electronic waste.

Then, by starting the first motor 208, the output shaft of the first motor 208 rotates to drive the connecting shaft 206 to rotate, and the connecting shaft 206 rotates to drive one of the pulleys 207 to rotate. The pulley 207 drives another pulley 207 to rotate through the belt transmission, so that one of the installation shafts 202 rotates. When the installation shaft 202 rotates, it cooperates with the two gears 204 to rotate the two crushing rollers 203. The crushing rollers 203 crush the large pieces of solid electronic waste into pieces that are easy to be processed later. The electronic waste particles, and the heating coil 11 can heat the chassis 201, so that the temperature inside the chassis 201 is increased and maintained, so that the solid electronic waste fragments in the chassis 201 are preheated to a certain temperature before the remaining process, which is conducive to better separation of rare earth materials. The heating coil 11 is spirally wound around the outer side of the chassis 201, so that the heating effect of the heating coil 11 on the chassis is more uniform and the heat transfer efficiency is higher. At the same time, the crushed materials will slide from the discharge pipe 209 into the quartz tube 302, and the high-frequency pulse power supply 301 and the graphite electrode 303 will heat the electronic solid waste block particles in the quartz tube 302 to a relatively high temperature. At high temperatures, the matrix layer will be cracked and delaminated under the action of the high-frequency and high-voltage pulse current generated by the high-frequency pulse power supply 301, making it easier for the rare earth elements contained therein to be separated from the matrix layer materials such as the circuit board, thereby increasing the yield of the leached product of the rare earth material, reducing the amount of materials used in the recycling process, reducing the pollution to the environment, and achieving the invention purpose of improving the comprehensive recycling rate of rare earth materials recovered from electronic solid waste and reducing the loss of resources in the extraction process. When heated to a certain degree, by starting the first hydraulic rod 505, the telescopic end of the first hydraulic rod 505 is extended to drive the connecting rod 504 to move. When the connecting rod 504 moves, it drives the sealing plate 502 to move. When the sealing plate 502 moves the circular through groove 503 to correspond to the quartz tube 302, the material will slide from the quartz tube 302 into the pickling barrel 402. The sliding of the sealing plate 502 and the fixed frame 501 avoids the gap between the quartz tube 302 and the pickling barrel 402 during the material feeding and stirring process, which causes the material to splash. .

[0039] Specifically, Figure 4 , Figure 7 , Fig. 9 and Fig.11 As shown, the pickling barrel 402 is fixedly connected with a connecting frame 8, a guide pipe 9 is installed on the connecting frame 8, a ball valve 10 is installed on the guide pipe 9, the filtering structure 7 includes a mounting frame 701 slidably connected to the connecting frame 8 and a filter screen 702 installed in the mounting frame 701, a third hydraulic rod 704 is installed on the connecting frame 8, the mounting frame 701 is fixedly connected to the telescopic end of the third hydraulic rod 704, a scraper 703 is fixedly connected in the mounting frame 701, a mounting rod 705 is installed on the connecting frame 8, a fourth hydraulic rod 706 is installed on the mounting rod 705, and a scraper rod 707 is installed at the telescopic end of the fourth hydraulic rod 706.

The filtering function is that when it is necessary to process the impurities on the filter screen 702, by starting the third hydraulic rod 704, the telescopic end of the third hydraulic rod 704 is extended to drive the installation frame 701 to slide outside the connecting frame 8, and the installation frame 701 slides to drive the scraper 703 to slide, so that the scraper 703 scrapes the impurities on the inner wall of the connecting frame 8, and the installation frame 701 slides to drive the filter screen 702 to move to the outside of the connecting frame 8, and then by starting the fourth hydraulic rod 706, the telescopic end of the fourth hydraulic rod 706 is extended to drive the scraper rod 707 to move downward, and the scraper rod 707 moves downward to scrape the impurities on the filter screen 702. The scraper rod 707 is driven to move by the fourth hydraulic rod 706, so that the impurities on the filter screen 702 can be automatically cleaned, and no frequent manual intervention is required during cleaning, which reduces the labor intensity, while improving the timeliness and effectiveness of cleaning, and can better maintain the filtering performance of the filter screen 702.

[0040] When the present invention is in use, the chain conveyor 12 is used to transport large pieces of solid electronic waste into the chassis 201, and then the first motor 208 is started. When the output shaft of the first motor 208 rotates, it drives the connecting shaft 206 to rotate. When the connecting shaft 206 rotates, it drives one of the pulleys 207 to rotate. The pulley 207 drives another pulley 207 to rotate through the belt transmission, so that one of the installation shafts 202 rotates.

The electronic waste material is crushed into electronic waste particles that are easy to be processed later. At the same time, the heating coil 11 can heat the chassis 201, so that the temperature inside the chassis 201 is increased and maintained, so that the solid electronic waste fragments in the chassis 201 are preheated to a certain temperature before the remaining processes are carried out, which is conducive to better separation of rare earth materials. The heating coil 11 is spirally wound around the outer side of the chassis 201, so that the heating effect of the heating coil 11 on the chassis is more uniform and the heat transfer efficiency is higher. At the same time, the crushed materials will slide from the discharge pipe 209 into the quartz tube 302, and the high-frequency pulse electric The source 301 and the graphite electrode 303 heat the electronic solid waste block particles in the quartz tube 302 to a relatively high temperature. The matrix layer will be cracked and delaminated under the action of the high-frequency and high-voltage pulse current generated by the high-frequency pulse power supply 301, making it easier for the rare earth elements contained therein to be separated from the matrix layer materials such as the circuit board, thereby increasing the leaching yield of the rare earth material, reducing the amount of materials used in the recycling process, and reducing the pollution to the environment, thereby achieving the goal of improving the comprehensive recycling rate of rare earth materials recovered from electronic solid waste and reducing the extraction process. The purpose of the invention is to reduce the loss of resources in the process. When heated to a certain degree, by starting the first hydraulic rod 505, the telescopic end of the first hydraulic rod 505 is extended to drive the connecting rod 504 to move, and the connecting rod 504 drives the sealing plate 502 to move. When the sealing plate 502 moves the circular through groove 503 to correspond to the quartz tube 302, the material will slide from the quartz tube 302 to the pickling barrel 402. The sealing plate 502 slides with the fixed frame 501, which avoids the gap between the quartz tube 302 and the pickling barrel 402 during the unloading and stirring process, causing the material to splash;

[0041] When the electronic waste material slides into the pickling barrel 402, a diluted inorganic acid solution is added into the barrel, and then the third motor 405 is started. When the output shaft of the third motor 405 rotates, the stirring shaft 404 is driven to rotate, and the stirring shaft 404 drives the installation sleeve 406 to rotate. When the installation sleeve 406 rotates, the stirring rod 407 is driven to rotate, so that the material and the inorganic acid solution are stirred, and the rare earth elements in the electronic waste particles are converted into a soluble rare metal salt solution by acid dissolution, thereby realizing the extraction of rare earth materials from the electronic waste. When the stirring rod 407 needs to be replaced, the stirring rod 407 is replaced by the stirring rod 407. By starting the second hydraulic rod 510, the telescopic end of the second hydraulic rod 510 extends and drives the fixed block 509 to move upward, the fixed block 509 drives the guide rod 508 to move upward, the guide rod 508 drives the slip ring 507 to move upward, the slip ring 507 drives the sealing ring 506 to move upward, the setting of the sealing ring 506 improves the sealing between the fixed frame 501 and the pickling barrel 402, and the upward movement of the sealing ring 506 avoids affecting the rotation of the pickling barrel 402. At this time, the second motor 403 is started, and the output shaft of the second motor 403 drives the rotating shaft 401 when it rotates. The rotating shaft 401 drives the pickling barrel 402 to rotate, so that the pickling barrel 402 rotates ninety degrees. At this time, the hexagonal sleeve can be inserted into the connecting block 606, and the connecting block 606 drives the screw rod 605 to rotate. When the screw rod 605 rotates, the thread drives the driving block 603 to slide toward each other. When the driving block 603 slides, the two driving shafts 602 roll and cooperate in the two driving grooves 604. Since the driving grooves 604 are inclined, the two mounting blocks 601 slide toward each other. When the mounting block 601 is no longer engaged with the mounting sleeve 406, the mounting sleeve 406 and the stirring shaft 40 4 and the positioning bar 607 slips off. The setting of the positioning bar 607 facilitates the positioning of the installation sleeve 406, and facilitates the two installation holes in the installation sleeve 406 to quickly correspond to the two installation blocks 601. By rotating the pickling barrel 402 by 90 degrees, a wide and easy-to-operate space is provided for the replacement of the stirring rod 407 in the barrel, which greatly reduces the difficulty and time cost of replacing the stirring rod 407. At the same time, the driving block 603 drives the two installation blocks 601 to slide at the same time, which facilitates the rapid installation of the installation sleeve 406 on the stirring shaft 404, thereby improving the efficiency of disassembly and assembly of the stirring rod 407.
