[0047] Other objects and advantages of the present application will become apparent from the following preferred embodiments of the present application.

[0048] Embodiment 1

[0049] Figure 1 The structure diagram of the high-performance multi-element alloy preparation device according to the first embodiment of the present application.

[0050] As shown in Figure 1 , the high-performance multi-element alloy preparation device according to the present application comprises a furnace body 100, and a furnace cover 110 is arranged on the upper side of the furnace body 100. A charging port 111 is arranged on the furnace cover 110 and penetrates the furnace cover 110 in the vertical direction, through which the material can be added into the furnace body 100. A plurality of through holes are arranged in the middle of the furnace cover 110 and penetrate the furnace cover 110 in the longitudinal direction, so as to allow the graphite electrode 120 to penetrate the through holes and heat the material in the interior of the furnace body 100.

[0051] Figure 2 The connection structure diagram of the charging unit 200, the material conveying unit 300 and the material storage unit 400 in the high-performance multi-element alloy preparation device according to the first embodiment of the present application.

[0052] As shown in Figure 1 and Figure 2 , the high-performance multi-element alloy preparation device according to the present application further comprises a charging unit 200, a material conveying unit 300 and a material storage unit 400. The material storage unit 400 is used for storing the material to be added into the interior of the furnace body 100, one end of the material conveying unit 300 is connected with the material storage unit 400, and the other end is connected with the charging unit 200, which is used for conveying the material in the material storage unit 400 to the charging unit 200. The charging unit 200 is used for adding the material into the furnace body 100.

[0053] Figure 3 The structure diagram of the charging unit 200 in the high-performance multi-element alloy preparation device according to the first embodiment of the present application.

[0054] In order to overcome the problem that in the prior art, when the material is added into the furnace body 100, the material only falls to the local area below the charging port 111 under the action of gravity, resulting in uneven charging. As Figures 1 to 3As shown, the feeding unit 200 of this embodiment includes a ball joint connection 210, a discharge pipe 220, and a drive unit 230. Under the action of the drive unit 230, the upper end of the discharge pipe 220 uses the ball joint connection 210 as a fulcrum, and the lower end of the discharge pipe 220 has a circular swing trajectory, thereby enabling the addition of materials to a wider range within the furnace body 100 and improving the uniformity of material addition into the furnace body 100.

[0055] Figure 4 This is a schematic diagram of the feeding unit 200 in the high-performance multi-element alloy preparation apparatus according to the first embodiment of the present invention. For clarity, the driving element 231 and the cover plate 262 have been removed.

[0056] like Figure 3 and Figure 4 As shown, the feeding unit 200 includes a housing 260, inside which are meshing drive gear 240 and driven gear 250, which are rotatably connected to the housing 260. The outer shell of the drive element 231 is fixedly connected to the housing 260, and the output end of the drive element 231 is connected to the drive gear 240 to drive the drive gear 240 to rotate. The drive gear 240 further drives the driven gear 250 to rotate around its own axis (i.e., the first central axis 257). The driven gear 250 is provided with a through drive hole 252, through which the lower end of the discharge pipe 220 passes and extends downward for a certain distance. It should be emphasized that the second central axis 258 of the drive hole 252 is offset from the first central axis 257 of the driven gear 250. Thus, when the driven gear 250 rotates about its own first central axis 257, the drive hole 252 pushes the unloading pipe 220 to make a conical pendulum motion with the ball joint connection 210 as the support point.

[0057] Figure 5 This is a cross-sectional view of the feeding unit 200 in the high-performance multi-element alloy preparation apparatus according to the first embodiment of the present invention. Figure 6 This is a cross-sectional view of the ball joint connection 210 in the high-performance multi-element alloy preparation apparatus of the first embodiment of the present invention. Figure 7 This is a top view of the driven gear 250 in the high-performance multi-element alloy preparation apparatus of the first embodiment of the present invention. Figure 8 for Figure 7 BB section view in the middle.

[0058] like Figures 5 to 8As shown, the housing 260 specifically comprises a base 261 and a cover plate 262, and a containing cavity 263 is formed between the cover plate 262 and the base 261 to contain the driving gear 240 and the driven gear 250. The output end of the driving element 231 is in transmission connection with the driving gear 240 through the cover plate 262 to drive the driving gear 240 to rotate. A limiting hole 264 is arranged at the bottom of the base 261. The lower surface of the driven gear 250 is provided with a downwardly protruding connecting part 251, which is in rotatable connection with the limiting hole 264.

[0059] The driving hole 252 of the driven gear 250 has an arc-shaped part 253 protruding radially inwardly, and a first tapered hole part 254 is arranged at the upper side of the arc-shaped part 253, the large end aperture of the first tapered hole part 254 being upwardly directed, and a second tapered hole part 255 is arranged at the lower side of the arc-shaped part 253, the large end aperture of the second tapered hole part 255 being downwardly directed. The above structure can avoid the mutual interference between the driving hole 252 and the outer wall surface of the discharge pipe 220 when the discharge pipe 220 makes a conical pendulum movement with the driven gear 250.

[0060] The ball-joint connecting part 210 comprises a spherical protrusion 221 fixed to the upper end of the discharge pipe 220, the spherical protrusion 221 having a substantially spherical outer surface, and the upper end of the spherical protrusion 221 has an inlet 223 for the material to flow into the discharge pipe 220. The ball-joint connecting part 210 further comprises a first outer spherical connecting part 212 in ball-joint connection with the outer surface of the spherical protrusion 221, the upper end of the first outer spherical connecting part 212 is connected with the receiving pipe 211, and the lower end of the first outer spherical connecting part 212 is provided with a first flange part 213. A second outer spherical connecting part 214 is arranged at the lower side of the first outer spherical connecting part 212, and the upper end of the second outer spherical connecting part 214 is provided with a second flange part 215 connected with the first flange part 213. The first flange part 213 and the second flange part 215 can be connected by a bolt assembly, for example. The lower end of the second outer spherical connecting part 214 is provided with an opening allowing the discharge pipe 220 to pass through and swing. Through the above ball-joint connecting part 210, the ball-joint connection is formed between the receiving pipe 211 and the discharge pipe 220, and the material passage 280 allowing the material to pass through is formed in both of them.

[0061] In the embodiment, as shown, Figures 1 to 8 The material conveying unit 300 conveys the material in the material storage unit 400 to the feeding unit 200, and the material flows to the discharge pipe 220 through the inner hole of the receiving pipe 211, and is added into the furnace body 100 by the discharge pipe 220. In the above process, the output end of the driving element 231 drives the driving gear 240 to rotate, and the driving gear 240 further drives the driven gear 250 to rotate, and the lower end of the discharge pipe 220 makes a conical pendulum movement with the driven gear 250 as the supporting point of the ball-joint connecting part 210, so that the material can be added into a wider range of the furnace body 100, and the uniformity of feeding the material into the furnace body 100 is improved.

[0062] Example 2

[0063] Figure 9 This is a schematic diagram of the connection structure of the feeding unit 200, the conveying unit 300 and the storage unit 400 in the high-performance multi-element alloy preparation device according to the second embodiment of the present invention. Figure 10 This is a schematic diagram of the feeding unit 200 in the high-performance multi-element alloy preparation device according to the second embodiment of the present invention. Figure 11 This is a bottom view of the unloading end 350 of the material conveying unit 300 in a high-performance multi-element alloy preparation apparatus according to an embodiment of the present invention.

[0064] During the implementation of this invention, the inventors of this application discovered that the high temperature inside the furnace body 100 adversely affects the service life of the drive element 231. Therefore, this embodiment 2 is a further improvement on embodiment 1, by removing the drive element 231 from embodiment 1.

[0065] The differences between Example 2 and Example 1 are described below, such as... Figures 9 to 11 As shown, in Embodiment 2, the driving element 231 is removed from Embodiment 1. The material conveying unit 300 has a material conveying driving element 310, which is used to drive the material conveying unit 300 to work. The material conveying driving element 310 drives the drive gear 240 to rotate through the transmission unit 270. Since the distance between the material conveying driving element 310 and the furnace cover 110 is greater than the distance between the driving element 231 and the furnace cover 110 in Embodiment 1, the material conveying driving element 310 is less affected by the high temperature of the furnace body 100, thus improving the service life of the driving components overall.

[0066] In this embodiment, a pinion 271 is installed on the output end of the material conveying drive element 310. The pinion 271 meshes with a large gear 272, which is further connected to the upper end of the transmission shaft 273. The lower end of the transmission shaft 273 is connected to the drive gear 240. In this embodiment, when the material conveying drive element 310 of the material conveying unit 300 is working, it can drive the feeding unit 200 and the material conveying unit 300 to work synchronously. It should be noted that the transmission unit 270 in this application can also be a chain drive, belt drive, or other transmission structure.

[0067] To facilitate understanding, the structure and working principle of the material conveying unit 300 are explained below, such as... Figure 9 and Figure 11 As shown, the material conveying unit 300 has a feed end 340 and a discharge end 350. The feed end 340 is installed at a low position, such as on the ground. The feed end 340 is located below the storage unit 400 and is connected to the discharge port 410 at the lower end of the storage unit 400 for receiving materials from the storage unit 400.

[0068] The first pipe 320 and the second pipe 330 are arranged between the feeding end 340 and the discharging end 350. A feeding rope 370 is arranged between the feeding end 340 and the discharging end 350, and a plurality of feeding discs 371 are arranged on the feeding rope 370 at equal intervals. Driving gears 360 are arranged in the feeding end 340 and the discharging end 350, and a plurality of toothed portions 361 are arranged on the driving gears 360. The feeding rope 370 is connected to the driving gears 360 and the toothed portions 361 in sequence. When the driving gears 360 rotate, the feeding discs 371 are driven to rotate by the toothed portions 361, and the feeding rope 370 is further driven to run in the feeding end 340, the first pipe 320, the discharging end 350 and the second pipe 330. At the same time, the feeding discs 371 obtain materials in the feeding end 340, and the materials are transported to the discharging end 350 through the first pipe 320 or the second pipe 330. The discharging end 350 is connected to the upper end of the receiving pipe 211 of the feeding unit 200, and the materials are transported to the feeding unit 200.

[0069] In the embodiment, the output end of the feeding driving element 310 is in transmission connection with the driving gears 360 in the discharging end 350, so that the feeding driving element 310 can drive the feeding unit 300 and the feeding unit 200 to run synchronously.

[0070] In other embodiments, the feeding driving element 310 can also be arranged in the feeding end 340 of the feeding unit 300, and the driving gears 360 on the discharging end 350 are driven to rotate through the feeding rope 370 and the feeding discs 371. The driving gears 360 on the discharging end 350 and the transmission unit 270 further drive the driving gear 240 and the driven gear 250 to rotate, so that the driving element is further away from the furnace body 100, and the service life of the driving element is improved.

[0071] Embodiment 3

Figure 13 The structure diagram of the feeding unit 200 in the high-performance multi-element alloy preparation device of the third embodiment of the present application. Figure 12 The connection structure diagram of the discharging pipe 220 and the driven gear 250. Figure 14 The structure diagram of the dispersing unit 500 in the high-performance multi-element alloy preparation device of the third embodiment of the present application, wherein the discharging pipe 220 is transparently processed (shown by a dashed line). Figure 15 The connection structure diagram of the dispersing unit 500 in the high-performance multi-element alloy preparation device of the third embodiment of the present application.

[0073] Example 3 further adds a dispersing unit 500 to Example 1, which is used to disperse the material passing through the feeding unit 200 to prevent the material from falling into the furnace body 100 in too concentrated form.

[0074] Specifically, such as Figures 12 to 15 As shown, the inner surface of the drive hole 252 of the driven gear 250 is provided with a plurality of circumferentially evenly arranged arc-shaped recesses 256. Correspondingly, a plurality of spherical protrusions 221 are provided at the corresponding positions of the unloading pipe 220, circumferentially surrounding the unloading pipe 220. It should be emphasized that the above-mentioned spherical protrusions 221 and the arc-shaped recesses 256 are in a one-to-one correspondence, and there is a relatively loose connection between the two. That is, the inner contour of the arc-shaped recess 256 is slightly larger than the outer contour of the spherical protrusion 221, and there is an appropriate gap between the two, so that they do not separate or jam, allowing the driven gear 250 to rotate, driving the unloading pipe 220 to perform a conical pendulum motion, while also driving it to rotate around its own axis (third central axis 224).

[0075] In this embodiment, a fixing part 520 is installed inside the receiving pipe 211. The fixing part 520 includes a support frame 521 fixed inside the receiving pipe 211 and an arc-shaped bent rod 523 fixedly connected to the support frame 521. Specifically, the support frame 521 includes a support shaft 522 coaxial with the inner hole of the receiving pipe 211. Both ends of the arc-shaped bent rod 523 are fixedly connected to the support shaft 522, and the middle part of the arc-shaped bent rod 523 is curved in an arc shape away from the support shaft 522 along the radial direction of the support shaft 522. Multiple arc-shaped bent rods 523 are evenly distributed circumferentially around the support shaft 522 to form a cage-like structure.

[0076] Further, the discharging pipe 220 is provided with a scattering part 510, which includes a rotating shaft 511 rotatably connected with the discharging pipe 220 (rotating around the fourth central axis 514), for example, a supporting block 222 can be arranged inside the discharging pipe 220, the rotating shaft 511 is rotatably connected with the supporting block 222 and axially limited by the supporting block 222. The upper end of the rotating shaft 511 is provided with a plurality of radial protrusions 512 extending away from the center of the rotating shaft 511 in the radial direction of the rotating shaft 511. The radial protrusions 512 are arranged in the gap between two adjacent arc-shaped bending rods 523. When the discharging pipe 220 rotates (rotating around the third central axis 224), the rotating shaft 511 inside the discharging pipe 220 rotates with the discharging pipe 220 around the central axis (the third central axis 224) of the discharging pipe 220, and under the interaction of the arc-shaped bending rods 523 and the radial protrusions 512, the rotating shaft 511 also rotates around the axis (the fourth central axis 514) of the rotating shaft 511. The lower end of the rotating shaft 511 is provided with a scattering head 513, which is not particularly limited in shape, for example, it can be a cage-shaped structure similar to the arc-shaped bending rods 523, or a fan-shaped structure.

[0077] In the embodiment, when the material in the feeding unit 200 passes through the inner hole of the discharging pipe 220, it is blocked and scattered by the fixing part 520, the radial protrusions 512 and the scattering head 513 in turn, and tends to be dispersed, thereby facilitating the uniform distribution of the material when entering the furnace body 100.

[0078] The high-performance multi-element alloy preparation device of the present application is described in detail with reference to the preferred technical solutions of the present application. However, it should be noted that any modification, modification and change can be made by those skilled in the art on the basis of the above disclosure without departing from the spirit of the present application. The present application includes the above specific embodiments and any equivalent forms thereof.
