Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0018] Refer to Figure 1 、 Figure 3 and Figure 4, an embodiment provided by the present invention: an automatic tailings discharge device for a high-gradient magnetic separator, comprising a fixed frame 1. In the middle of the inner wall of the fixed frame 1, a bottom plate 3 is fixedly connected. On the front side of the inner wall of the bottom plate 3, a feed hole 4 is opened. On the bottom of the inner wall of the bottom plate 3, a discharge hole 5 is opened. On the bottom of the inner wall of the bottom plate 3, a partition 6 is fixedly connected. A plurality of square holes 7 are opened on the outer wall of the partition 6. At the top of the inner wall of the partition 6, a magnetic block 8 is fixedly connected. On the top of the outer wall of the magnetic block 8, a gasket 9 is fixedly connected. On the left side of the top of the fixed frame 1, a motor 10 is fixedly connected. The output end of the motor 10 is fixedly connected with a first gear 11. The outer wall of the first gear 11 is rotationally connected with a belt 12. On the top of the outer wall of the fixed frame 1, a rotating shaft 14 is rotationally connected. On the left end of the outer wall of the rotating shaft 14, a second gear 13 is fixedly connected. The first gear 11 is drivingly connected with the rotating shaft 14 through the belt 12. Around the outer wall of the rotating shaft 14, a spiral blade 15 is fixedly connected. At equal intervals on the outer wall of the spiral blade 15, fan-shaped holes 16 are opened. Around the outer wall of the fan-shaped holes 16, a fixed cylinder 17 is arranged. On the rear side of the outer wall of the fixed frame 1, a flushing mechanism 2 is fixedly connected. The flushing mechanism 2 is used for flushing and cleaning minerals. On the left and right ends of the outer wall of the fixed cylinder 17, baffles 18 are fixedly connected. On the adjacent side of the inner wall of the baffles 18, a sealing ring 19 is fixedly connected; Specifically, minerals enter the device through the feed hole 4 and fall on the bottom plate 3. After the motor 10 is started, the first gear 11 rotates, drives the rotating shaft 14 through the belt 12, and the spiral blade 15 rotates accordingly, stirring and turning the minerals to facilitate subsequent separation. The fan-shaped holes 16 initially screen the minerals, reduce the diameter, and improve the magnetic separation effect. The magnetic block 8 attracts magnetic minerals, while non-magnetic minerals move under the action of gravity and the spiral blade 15 and are discharged through the discharge hole 5. The square holes 7 on the partition 6 dredge the minerals to prevent blockage. The fixed cylinder 17 prevents the minerals from splashing and keeps the environment clean. The gasket 9 protects the magnetic block 8 and extends its service life. The bottom plate 3 and the partition 6 prevent the minerals from falling and separate the minerals respectively, making the device work more orderly and efficiently. The rear side of the outer wall of the fixed frame 1 is connected with the flushing mechanism 2. The main function of the flushing mechanism 2 is to flush and clean the minerals, which can effectively improve the cleaning efficiency and the cleanliness of the minerals. On the left and right ends of the outer wall of the fixed cylinder 17, baffles 18 are fixedly connected. On the adjacent side of the inner wall of these baffles 18, a sealing ring 19 is fixedly connected. The function of the baffle 18 is to prevent the minerals from overflowing from both ends of the fixed cylinder 17 during the cleaning process, while the sealing ring 19 ensures the sealing performance of the whole device, prevents the leakage of minerals, and thus guarantees the safety and efficiency of the processing process.

[0019] Refer to Figure 1 , Figure 2 and Figure 5, the flushing mechanism 2 includes a fixed groove 201 which is fixedly connected to the rear side of the outer wall of the fixed frame 1. At the bottom of the outer wall of the fixed groove 201, a sorting pipe 202 is fixedly connected. On one side of the inner wall of the sorting pipe 202, a sieve 203 is fixedly connected. On the right side of the top of the fixed groove 201, a water pump 204 is fixedly connected. One end of the water pump 204 communicates with a water guide pipe 205. The outer wall of the water guide pipe 205 is equidistantly provided with branch water pipes 206. At the rear side of the top of the fixed frame 1, an electric push rod 208 is fixedly connected. The output end of the electric push rod 208 is fixedly connected with a spring column 207. The spring column 207 is fixedly connected to the left end of the outer wall of the branch water pipe 206. At the front side of the top of the fixed frame 1, a cover plate 20 is rotatably connected. On the front side of the outer wall of the cover plate 20, a handle 21 is fixedly connected. At the left and right ends of the outer wall of the rotating shaft 14, support frames 22 are rotatably connected. Screws 23 are threadedly connected to the front and rear sides of the outer walls of the two support frames 22; Specifically, the water pump 204 extracts water and transports it through the water guide pipe 205. The outer wall of the water guide pipe 205 is provided with branch water pipes 206, and water sprays out from the branch water pipes 206. The electric push rod 208 pushes the spring column 207 to make the movement of the branch water pipe 206 stable. Controlled by the electric push rod 208, the position and angle of the branch water pipe 206 are adjusted to change the spraying range and direction, and the object is flushed. The flushed object enters the sorting pipe 202. The sieve 203 allows small particles to pass through, and large particles are blocked to achieve sorting. The front side of the top of the fixed frame 1 is connected to the cover plate 20 in a rotatable connection manner, so that the cover plate 20 can be flexibly opened and closed. The handle 21 is fixedly connected to the front side of the outer wall of the cover plate 20, which is convenient for users to easily operate the cover plate 20 when needed. Support frames 22 are rotatably connected to the left and right ends of the rotating shaft 14, which not only enhances the structural stability but also allows the support frames 22 to rotate freely within a certain range to adapt to different usage scenarios. To further strengthen the fixing effect of the support frames 22, screws 23 are threadedly connected to the front and rear sides of their outer walls, ensuring the firmness and durability of the entire structure.

[0020] Refer to Figure 1 , Figure 2 and Figure 3 , the outer wall of the water guide pipe 205 is equidistantly fixedly connected with fixing buckles 24. On one side of the outer wall of the fixing buckle 24, a bolt 25 is threadedly connected. At the top of the outer wall of the feed hole 4, a fixing frame 26 is fixedly connected. Fixing holes 27 are opened around the outer wall of the fixing frame 26. On the left side of the top of the fixed groove 201, a sealing box 28 is fixedly connected. On the left and right sides of the top of the fixed groove 201, hanging rings 29 are fixedly connected; Specifically, the fixed groove 201 is fixed at the rear side of the fixed frame 1. The fixed frame 26 and the fixed hole 27 at the feeding hole 4 facilitate the access of materials. The water pump 204 pumps water and conveys it through the water conduit 205. The branch water pipe 206 is stably connected to the water conduit 205 through the fixing buckle 24 and the bolt 25. The electric push rod 208 pushes the branch water pipe 206 with the help of the spring column 207 to adjust the water spray, dispersing the materials in the fixed groove 201. The dispersed materials enter the sorting pipe 202 and are sorted by the sieve 203. The sealing box 28 on the left side of the top of the fixed groove 201 plays a sealing role. The hanging rings 29 on the left and right sides of the top facilitate the hoisting and moving of the device. The cover plate 20 can be opened and closed by rotating through the handle 21. The rotating shaft 14 is supported and fixed by the support frame 22 and the screw 23. 15 Working principle: The minerals to be processed enter the interior of the device through the feeding hole 4 and fall on the bottom plate 3. The motor 10 starts and drives the first gear 11 to rotate. The first gear 11 drives the rotating shaft 14 to rotate through the belt 12. The spiral blades on the rotating shaft 14 rotate accordingly, stirring and turning over the minerals, enabling the minerals to be fully mixed and flipped, facilitating subsequent separation operations. At the same time, the fan-shaped holes 16 on the spiral blade 15 can preliminarily screen the minerals, reducing the diameter of the minerals, which is beneficial to improving the magnetic separation effect. During the process of the minerals being stirred and turned over, the magnetic block 8 located at the top inner wall of the partition plate 6 will generate an attractive force on the magnetic minerals, adsorbing the magnetic minerals near the magnetic block 8, while the non-magnetic minerals will continue to move under the action of gravity and the spiral blade 15. After magnetic separation, the non-magnetic minerals are automatically discharged as tailings through the discharge hole 5. The square holes 7 on the partition plate 6 play a dredging role, ensuring that the minerals can smoothly pass through the partition plate 6, preventing blockage, and ensuring the smooth progress of the entire separation and discharge process. At the same time, the fixed cylinder 17 can prevent the minerals from splashing out during the stirring process, ensuring the cleanliness of the working environment. The gasket 9 on the top outer wall of the magnetic block 8 can prevent the magnetic block 8 from being worn during the working process while ensuring the magnetic separation effect, extending the service life of the magnetic block 8. The bottom plate 3 and the partition plate 6 respectively play the roles of preventing the minerals from falling and separating the separated minerals, making the work of the entire device more orderly and efficient; When the water pump 204 is working, it pumps water from the water source and conveys it through the water conduit 205. Since the outer wall of the water conduit 205 is equidistantly provided with branch water pipes 206, the water will spray out from these branch water pipes 206. The electric push rod 208 can push the spring column 207 through its output end, thereby driving the movement of the branch water pipe 206. The spring column 207 plays a certain buffering and elastic support role, making the movement of the branch water pipe 206 smoother. In this way, by controlling the telescopic movement of the electric push rod 208, the position and angle of the branch water pipe 206 can be adjusted, so as to change the spraying range and direction, and disperse the objects in the fixed groove 201. The dispersed objects enter the sorting pipe 202. Since one side of the inner wall of the sorting pipe 202 is fixedly connected with a sieve mesh 203, smaller particles or objects that meet the aperture of the sieve mesh 203 can fall through the sieve mesh 203, while larger objects are blocked by the sieve mesh 203, thus realizing the sorting of objects.

[0021] 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. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
