[0002] Rare earth disk separation technology is a highly efficient technology for separating rare earth elements. It is mainly used in mining, raw material processing and waste treatment. This technology separates rare earth elements from ores and waste by utilizing the characteristics of the disk, thereby achieving efficient and energy-saving mineral resource recovery. It can effectively remove heavy metals, ions and other harmful substances from wastewater, ensuring the recovery rate and quality of rare earth elements, while reducing environmental pollution.
[0003] When using a wastewater purification device for rare earth recycling, the limited contact area between the internal disk and the sewage directly affects the wastewater treatment effect.
[0004] Therefore, a rare earth recycling and wastewater purification device is needed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a rare earth recycling wastewater purification device to solve the problem of poor disk processing efficiency in rare earth recycling wastewater purification devices mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rare earth recycling wastewater purification device, comprising a treatment tank, an inlet pipe, and a drain pipe. The treatment tank is equipped with a rotary magnetic separator, which includes a partition, a rotating groove, a magnetic disk, and a motor. A partition is located at the center of the treatment tank, and a rotating groove is located at the top of the partition. A magnetic disk is movably mounted inside the rotating groove. A motor is installed at the center of the top of the treatment tank, and the motor output extends into the interior of the treatment tank. The motor output is fixedly connected to the center of the top of the magnetic disk.
[0007] As a further technical solution of this utility model, a water inlet pipe is installed on the left side of the top of the treatment box, and drain pipes are installed at the bottom of both sides of the treatment box.
[0008] As a further technical solution of this utility model, an adjustment platform is fixed to the top right side of the processing box, and a screw hole is provided inside the adjustment platform, and a lead screw is provided inside the screw hole.
[0009] As a further technical solution of this utility model, the right side of the lead screw extends to the outside of the processing box, and a handwheel is installed on the right side of the lead screw.
[0010] As a further technical solution of this utility model, the left side of the lead screw extends into the interior of the processing box, a scraping platform is movably installed on the left side of the lead screw, and a scraper is installed on the left side of the scraping platform.
[0011] As a further technical solution of this utility model, a guide groove is provided on the left side surface of the adjustment table, and a guide rod is movably installed inside the guide groove. The left side of the guide rod is fixedly connected to the right side of the scraping table.
[0012] As a further technical solution of this utility model, a filter box is installed at the top left side inside the processing box, a filter groove is provided at the bottom of the filter box, and a filter screen is installed inside the filter groove.
[0013] As a further technical solution of this utility model, a sewage pipe is installed at the top left side of the processing box, and a sealing cover is provided inside the sewage pipe.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a disk, the disk is distributed in a conical shape inside the treatment box for use. When sewage enters, it can be directly poured onto the surface of the disk, thereby separating the rare earth elements in the sewage. During this process, the motor is started to drive the disk to rotate slowly, changing the contact position between the sewage and the disk, avoiding the adsorbed rare earth elements being washed away by the water flow, or the adsorbed rare earth elements affecting the subsequent adsorption and separation operation, thus enhancing the rare earth element separation effect when the rare earth recovery and wastewater purification device is used.
[0015] By setting a lead screw, when the lead screw is turned by handwheel, the lead screw engages with the screw hole thread, which can push the inner scraper platform, scraper and disk closer, adjust the distance between the scraper and disk, and assist the scraper to scrape the surface of the disk, thus realizing the adjustment function of the scraper of the rare earth recycling wastewater purification device.
[0016] By installing a filter box located below the inlet pipe, as wastewater enters the filter box through the inlet pipe, the filter screen inside the filter tank at the bottom of the filter box can assist in separating larger impurities in the wastewater. This prevents larger impurities from adhering to the surface of the disk and thus affecting its use, thereby realizing the pretreatment function of the wastewater purification device for rare earth recycling.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 The present invention provides an embodiment of a rare earth recycling wastewater purification device, comprising a treatment tank 1, an inlet pipe 6, and a drain pipe 7. The treatment tank 1 is equipped with a rotary magnetic separation assembly, which includes a partition 2, a rotating groove 3, a magnetic disk 4, and a motor 5. The partition 2 is located at the center of the treatment tank 1, and the rotating groove 3 is located at the top of the partition 2. The magnetic disk 4 is movably installed on the inner side of the rotating groove 3. The motor 5 is installed at the center of the top of the treatment tank 1, and the output end of the motor 5 extends into the interior of the treatment tank 1. The output end of the motor 5 is fixedly connected to the center of the top of the magnetic disk 4. The inlet pipe 6 is installed on the left side of the top of the treatment tank 1, and the drain pipe 7 is installed at the bottom of both sides of the treatment tank 1.
[0024] Specifically, such as Figure 1 and Figure 2 As shown, when the wastewater enters the treatment tank 1 through the inlet pipe 6, it can directly contact the surface of the disk 4. The disk 4 has a conical design. As the wastewater flows downward along the disk 4, the rare earth elements in the wastewater are adsorbed on the surface of the disk 4. During this process, the motor 5 drives the disk 4 to rotate slowly. The rotating disk 4 can change the contact position with the wastewater, so as to avoid the adsorbed rare earth elements from affecting the subsequent treatment effect.
[0025] An adjustment platform 8 is fixed to the top right side of the inside of the processing box 1. The adjustment platform 8 has a screw hole 9 inside, and a lead screw 10 is installed inside the screw hole 9. The right side of the lead screw 10 extends to the outside of the processing box 1. A handwheel 11 is installed on the right side of the lead screw 10. The left side of the lead screw 10 extends into the inside of the processing box 1. A scraper 12 is movably installed on the left side of the lead screw 10. A scraper 13 is installed on the left side of the scraper 12. A guide groove 14 is provided on the surface of the left side of the adjustment platform 8. A guide rod 15 is movably installed inside the guide groove 14. The left side of the guide rod 15 is fixedly connected to the right side of the scraper 12.
[0026] Specifically, such as Figure 1 and Figure 3 As shown, when in use, turning the handwheel 11 and engaging the screw 10 with the screw hole 9 will push the scraper 13 to move, adjusting the distance between the scraper 13 and the surface of the disk 4. When the disk 4 rotates, the scraper 13 can assist in scraping the surface of the disk 4 to separate the objects adsorbed on the surface of the disk 4.
[0027] A filter box 16 is installed at the top left side inside the treatment box 1. A filter tank 17 is provided at the bottom of the filter box 16. A filter screen 18 is installed inside the filter tank 17. A drain pipe 19 is installed at the top left side inside the treatment box 1. A sealing cover 20 is provided inside the drain pipe 19.
[0028] Specifically, such as Figure 1 and Figure 4 As shown, when in use, sewage enters through the inlet pipe 6 and first enters the interior of the filter box 16. The filter screen 18 at the bottom of the filter box 16 can first process larger debris in the sewage. The drain pipe 19 is connected to the lowest point of the filter screen 18. The sealing cover 20 is sealed at the opening of the drain pipe 19 by a threaded cover. Later, after rotating the sealing cover 20 and removing it, the debris separated by the filter screen 18 can be cleaned with the help of the drain pipe 19.
[0029] Working principle: During use, the partition 2 inside the treatment tank 1 divides the internal space of the treatment tank 1 into two sets of chambers, left and right. A disk 4 is movably installed in the rotating groove 3 at the top, located between the two sets of chambers. As wastewater enters the left chamber inside the treatment tank 1 through the inlet pipe 6, it first enters the filter box 16 below the inlet pipe 6. The filter screen 18 at the bottom of the filter box 16 can first treat larger impurities in the wastewater. The treated wastewater then directly contacts the surface of the disk 4. The disk 4 has a conical design. As the wastewater flows downwards along the disk 4, rare earth elements in the wastewater are removed. Elements are adsorbed on the surface of disk 4. During this process, the start motor 5 drives disk 4 to rotate slowly. The rotating disk 4 can change the contact position with sewage, so as to avoid the adsorbed rare earth elements affecting the subsequent treatment effect. During the rotation of disk 4, it comes into contact with scraper 13 in the right chamber. Scraper 13 can assist in scraping the surface of disk 4 and separating the adsorbed objects on the surface of disk 4. By turning the handwheel 11, the lead screw 10 and the screw hole 9 can push scraper 13 to move. Adjusting the distance between scraper 13 and the surface of disk 4 can adjust the scraping effect of scraper 13.
