Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the utility model.

[0031] Refer to Figure 1, Figure 3 and Figure 4 , an embodiment provided by the utility model: a magnetic suspension liquid stirring mechanism, including a stirring barrel 1, a liquid inlet pipe 7 and a feeding port 8 are fixedly connected to the top of the stirring barrel 1. The liquid inlet pipe 7 facilitates pouring the dispersant into the interior of the stirring barrel 1, and the feeding port 8 facilitates pouring the magnetic powder into the interior of the stirring barrel 1. A filter plate 17 is fixedly connected to the interior of the stirring barrel 1, and the filter plate 17 can filter the mixed magnetic suspension liquid. A liquid discharge pipe 3 is fixedly connected to the bottom of the stirring barrel 1. A first rotating rod 9 is rotatably connected to the middle of the stirring barrel 1. An extrusion plate 15 is fixedly connected to the bottom of the first rotating rod 9. When the first rotating rod 9 rotates, it will drive the extrusion plate 15 to move simultaneously. A spring rod 18 is fixedly connected to the bottom of the extrusion plate 15. When the extrusion plate 15 moves, it will drive the spring rod 18 to move simultaneously. A brush 20 is fixedly connected to the bottom of the spring rod 18. When the spring rod 18 moves, it will drive the brush 20 to move, and the brush 20 can clean the filter plate 17, thereby preventing the filter plate 17 from being blocked. A compression spring 19 is fixedly connected to the top of the brush 20, and the other end of the compression spring 19 is fixedly connected to the bottom of the extrusion plate 15. The compression spring 19 is sleeved on the outer periphery of the spring rod 18. A driving component is provided at the top of the stirring barrel 1.

[0032] Referring to Figure 3 and Figure 4 , the driving component includes a support block 5, the support block 5 is fixedly connected to the top of the stirring barrel 1, a motor 6 is fixedly connected to the middle of the support block 5, and the support block 5 can support the motor 6, so that the motor 6 can work better. One end of the first rotating rod 9 is fixedly connected to the output end of the motor 6. When the motor 6 works, it will drive the first rotating rod 9 to rotate. Two second rotating rods 12 are rotatably connected to the interior of the stirring barrel 1. A second gear 11 is fixedly connected to the top of each of the two second rotating rods 12. A first gear 10 is fixedly connected to the top of the first rotating rod 9. Both of the two second gears 11 are meshed with the first gear 10. When the first gear 10 rotates, it will drive the two second gears 11 to rotate simultaneously. When the first gear 10 and the second gears 11 rotate simultaneously, they will drive the first rotating rod 9 and the two second rotating rods 12 to rotate simultaneously. A plurality of stirring rollers 14 are fixedly connected to the outer peripheries of the two second rotating rods 12 and the first rotating rod 9. When the two second rotating rods 12 and the first rotating rod 9 rotate simultaneously, they will drive the plurality of stirring rollers 14 to move simultaneously. A cleaning component is arranged in the interior of the stirring barrel 1.

[0033] Referring to Figures 2 - 4, the cleaning component includes a scraper 16. Specifically, there are two scrapers 16. One scraper 16 is fixedly connected to one end of the extrusion plate 15, and the other scraper 16 is fixedly connected to the other end of the extrusion plate 15. The two scrapers 16 can scrape the inner wall of the stirring barrel 1, thereby preventing the magnetic suspension from adhering to the inner wall of the stirring barrel 1. Limiting blocks 13 are fixedly connected to the outer peripheries of the first rotating rod 9 and the two second rotating rods 12. The limiting blocks 13 can limit the first rotating rod 9 and the two second rotating rods 12, thereby preventing the first rotating rod 9 and the second rotating rods 12 from shifting during rotation. The first gear 10 and the two second gears 11 are both rotatably connected to the top of the stirring barrel 1.

[0034] Refer to Figure 1 , a plurality of support legs 2 are fixedly connected to the bottom of the stirring barrel 1. The plurality of support legs 2 can support the stirring barrel 1 more firmly. A valve 4 is fixedly connected to the middle of the liquid discharge pipe 3. The valve 4 facilitates controlling the opening or closing of the liquid discharge pipe 3.

[0035] Working principle: When stirring, first pour magnetic powder and dispersant into the interior of the stirring barrel 1 through the motor 6 and the feed port 8. After pouring, start the motor 6 so that the motor 6 operates. When the motor 6 operates, it will drive the first rotating rod 9 and the first gear 10 to rotate simultaneously. When the first gear 10 rotates, it will drive the two second gears 11 to rotate simultaneously. When the two second gears 11 rotate, they will drive the two second rotating rods 12 to rotate simultaneously. When the two second rotating rods 12 and the first rotating rod 9 rotate simultaneously, they will drive a plurality of stirring rollers 14 to move, thereby making the stirring and mixing effect of the magnetic powder and the dispersant better, thereby improving the performance of the magnetic suspension and at the same time improving the working efficiency.

[0036] When cleaning the filter plate 17, the first rotating rod 9 will drive the extrusion plate 15 to rotate. When the extrusion plate 15 rotates, it will drive the spring rod 18 and the compression spring 19 to move simultaneously. When the spring rod 18 and the compression spring 19 move, they will drive the brush 20 to move. When the brush 20 moves, it will brush the filter plate 17, thereby preventing the filter plate 17 from being blocked due to long-term filtration. At the same time, the filter plate 17 filters the mixed magnetic suspension, thereby preventing impurities in the magnetic suspension from affecting the performance of the magnetic suspension.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
