In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0033] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0034] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0035] Example, referring to Figure 1 , which is an embodiment of the present invention, a sorting device for producing spherical magnesium powder is proposed, including a sorting box 1, a box cover 2, a screen 3, and a guide cylinder 4. The box cover 2 is arranged at the upper opening of the sorting box 1. The box cover 2 has a feed inlet 5, and the feed inlet 5 is located at the center of the box cover 2. The screen 3 is arranged inside the sorting box 1. The guide cylinder 4 is arranged inside the sorting box 1 and is located between the feed inlet 5 and the screen 3. The number of the guide cylinders 4 is at least two, and all the guide cylinders 4 are coaxially arranged. The diameter of the guide cylinder 4 linearly increases from top to bottom, and the outer diameter of the upper end surface of the outermost guide cylinder 4 is smaller than the diameter of the feed inlet 5.

[0036] In this embodiment, all the flow guide tubes 4 are at the same height. The material drops vertically from the feed inlet 5 of the box cover 2 and is divided into at least three parts by the flow guide tubes 4. The material at the center enters the flow guide tube 4 at the center and then drops. The other parts of the material will scatter around during the dropping process as the diameter of the flow guide tube 4 increases. In this way, the contact area between the material and the screen 3 can be increased, the accumulation of the material below the feed inlet 5 can be avoided, and the sorting efficiency of the screen 3 can be improved.

[0037] Further, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the side wall of the flow guide tube 4 has a first positioning hole 6 and a second positioning hole 7. The upper end face of the sorting box 1 has a first receiving groove 8 and a second receiving groove 9. It also includes a first support rod 10 and a second support rod 11. The first support rod 10 passes through the first positioning holes 6 on all the flow guide tubes 4, and the end of the first support rod 10 is clamped with the first receiving groove 8; the number of the second support rods 11 is two, and the two second support rods 11 are symmetrically arranged along the axial direction of the first support rod 10. The inner end of the second support rod 11 passes through the second positioning hole 7 on one side of the second support rod 11 and is threadedly connected to the second support rod 11, and the outer end of the second support rod 11 is clamped with the second receiving groove 9.

[0038] Taking the flow guide tube 4 having two first positioning holes 6 on the left and right and two second positioning holes 7 in the front and back as an example, the upper end face of the sorting box 1 has two first receiving grooves 8 on the left and right and two second receiving grooves 9 in the front and back. The first support rod 10 passes through the first positioning holes 6 on all the flow guide tubes 4 in the left-right direction, and the left and right ends of the first support rod 10 are both clamped with the first receiving grooves 8 on the upper end face of the sorting box 1 to provide support and positioning for the first support rod 10 and the flow guide tube 4. The rear end of one second support rod 11 passes through all the second positioning holes 7 in front of the first support rod 10 and is threadedly connected to the front side of the second support rod 11, and the front end of the other second support rod 11 passes through all the second positioning holes 7 behind the first support rod 10 and is threadedly connected to the rear side of the second support rod 11 to provide support and positioning for the second support rod 11 and the flow guide tube 4. The first support rod 10 and the second support rod 11 cooperate to ensure that the flow guide tube 4 can be coaxially and stably fixed in the sorting box 1 and prevent the flow guide tube 4 from shifting or vibrating when the material drops.

[0039] Furthermore, the depth of the first receiving groove 8 is equal to the diameter of the first support rod 10, and the depth of the second receiving groove 9 is equal to the diameter of the second support rod 11. When the end of the first support rod 10 is clamped with the first receiving groove 8, the first support rod 10 will be completely embedded in the first receiving groove 8 to form a plane. When the end of the second support rod 11 is clamped with the second receiving groove 9, the second support rod 11 will be completely embedded in the second receiving groove 9 to also form a plane. There is no need to open grooves on the box cover 2 to accommodate the first support rod 10 and the second support rod 11, making the structure of the entire device simpler and facilitating processing.

[0040] Furthermore, as Figure 1 and Figure 5 shown, the lower end surface of the box cover 2 has a positioning convex ring 12. The positioning convex ring 12 is inserted into the sorting box 1, and the outer wall of the positioning convex ring 12 contacts the inner wall of the sorting box 1. The lower end surface of the positioning convex ring 12 has a first groove 13 and a second groove 14. The first support rod 10 is clamped with the first groove 13, and the second support rod 11 is clamped with the second groove 14. The insertion fit between the positioning convex ring 12 and the sorting box 1 ensures that the box cover 2 can be accurately positioned during installation, avoiding installation errors and improving the assembly accuracy. The close contact between the positioning convex ring 12 and the inner wall of the sorting box 1 can form a stable mechanical connection, ensuring the connection stability between the box cover 2 and the sorting box 1 even under vibration or impact during the material sorting process. The clamping of the first support rod 10 with the first groove 13 and the second support rod 11 with the second groove 14 can make the positioning of the first support rod 10 and the second support rod 11 between the box cover 2 and the sorting box 1 more stable, preventing the first support rod 10 and the second support rod 11 from shifting during operation.

[0041] Furthermore, as Figure 6 shown, it further includes a telescopic rod 15. At least three telescopic rods 15 are arranged circumferentially between two adjacent flow guide cylinders 4. The inner end of the telescopic rod 15 is inserted into the flow guide cylinder 4 located inside it, and the outer end of the telescopic rod 15 is inserted into the flow guide cylinder 4 located outside it.

[0042] The two ends of the telescopic rod 15 are respectively inserted into the inner and outer guide cylinders 4, and multiple telescopic rods 15 form an annular support network. This can not only prevent the guide cylinder 4 from shifting or deforming due to the impact force when the material falls, but also effectively disperse the pressure generated by the falling material on the guide cylinder 4, improving the structural stability and durability of the entire device. The telescopic rod 15 can also play a certain guiding and dispersing role for the material, enabling the material to be more evenly distributed on the sieve mesh 3, avoiding the material from concentrating and piling up in a certain area, thereby improving the uniformity and efficiency of sorting. By adjusting the length of the telescopic rod 15, it is convenient for the disassembly and assembly of the telescopic rod 15. Moreover, by adjusting the length of the telescopic rod 15 and selecting a guide cylinder 4 with an appropriate diameter, the distance between adjacent guide cylinders 4 can be adjusted according to actual needs to adapt to the sorting requirements of materials with different particle sizes.

[0043] Furthermore, the lid 2 and the sorting box 1 are detachably connected, which is convenient for the disassembly and maintenance of each component inside the sorting box 1.

[0044] Furthermore, as Figure 1 shown, it further includes a lower support ring 16 and an upper pressing ring 17. The lower support ring 16 is arranged inside the sorting box 1; the upper pressing ring 17 is detachably arranged on the lower support ring 16, and the sieve mesh 3 is clamped between the lower support ring 16 and the upper pressing ring 17. The diameter of the sieve mesh 3 is larger than the inner diameters of the lower support ring 16 and the upper pressing ring 17, and less than or equal to the outer diameters of the lower support ring 16 and the upper pressing ring 17. The lower support ring 16 is arranged inside the sorting box 1, and its main function is to provide a solid bottom support for the sieve mesh 3. The upper pressing ring 17 is detachably arranged on the lower support ring 16, and its function is to apply a downward pressure on the sieve mesh 3 to ensure that the sieve mesh 3 is in close contact with the lower support ring 16. The detachable design of the upper pressing ring 17 makes the replacement and cleaning of the sieve mesh more convenient and can improve the maintenance efficiency of the device. The sieve mesh 3 is clamped between the lower support ring 16 and the upper pressing ring 17, and this clamping mechanism can ensure the stability of the sieve mesh during the sorting process, preventing the sieve mesh 3 from loosening or displacing due to the impact of the material or the vibration of the device. At the same time, the close contact between the sieve mesh 3 and the lower support ring 16 and the upper pressing ring 17 also helps to extend the service life of the sieve mesh 3 and reduce the leakage of materials during the screening process.

[0045] Furthermore, as Figure 1 shown, the height of the upper pressing ring 17 gradually increases from the inside to the outside, so that the upper end surface of the upper pressing ring 17 forms an inclined surface. After the material falls on the upper pressing ring 17, it will slide down along the inclined surface and fall on the sieve mesh 3, which can prevent the material from piling up on the upper pressing ring 17.

[0046] Furthermore, as Figure 1As shown, the bottom of the sorting box 1 is a conical structure. At the center of the bottom of the sorting box 1, there is a discharge port. It also includes a receiving box 18. The receiving box 18 is located below the sorting box 1, and the discharge port is communicated with the receiving box 18. The design of the bottom of the conical structure is beneficial to the smooth flow of materials. When the materials are screened, the finer particles will fall through the screen 3 to the bottom of the sorting box 1. The conical structure can guide these materials to gather towards the center, which helps to increase the flow rate of the materials, so that the materials can smoothly pass through the discharge port at the center and enter the receiving box 18, avoiding the accumulation of materials at the bottom of the sorting box 1. The use of the receiving box 18 can facilitate the subsequent collection and processing of materials.

[0047] Furthermore, as Figure 1 shown, it also includes elastic members 19. The lower ends of the elastic members 19 are connected to the receiving box 18, and the upper ends of the elastic members 19 are connected to the sorting box 1. The number of elastic members 19 is at least three, and all the elastic members 19 are evenly arranged along the circumferential direction of the sorting box 1. Using multiple elastic members 19 forms a "suspension" - type connection between the sorting box 1 and the receiving box 18, and enables the sorting box 1 to be evenly supported in all directions, playing the role of supporting the weight of the sorting box 1. When the sorting box 1 is driven to vibrate by a vibration motor, the elastic members 19 can make the sorting box 1 vibrate with a sufficient amplitude. The sorting box 1 drives the screen 3 and the materials to vibrate, which can improve the sorting efficiency.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
