Description

Technical Field

[0001] The utility model relates to the technical field of material guiding in smelting furnaces, in particular to a material guiding device in a connecting section in a smelting furnace. Background Art

[0002] Tantalum is a rare transition metal that is hard and highly corrosion-resistant. It is widely used in the manufacture of high-strength alloy steels, superalloys, or carbide-reinforced tools. Tantalum's excellent corrosion resistance means it can be used in the manufacture of chemical process equipment, medical devices, and implants. Electron beam melting refers to a vacuum melting method that converts the kinetic energy of a high-speed electron beam into thermal energy as a heat source for metal melting under high vacuum. Electron beam melting requires a high vacuum environment to function properly. For the production of tantalum oxide, tantalum metal plates or tantalum ingots are used as the initial product. After processing in an electron beam melting furnace, tantalum oxide or tantalum carbide is obtained to meet subsequent manufacturing needs. Crucibles are generally used in the electron beam melting furnace to melt the metal plates or tantalum ingots. The crucibles are generally used to complete the oxidation process of the metal plates or tantalum ingots in the vacuum furnace. During the oxidation process, the material is transported into the vacuum furnace by a feed track, and then the material falls into the crucible body.

[0003] Since there is a certain gap in the connecting section between the feed track and the crucible body, in order to prevent the material from falling directly into the furnace body, it is necessary to set a material guide structure in the connecting section. The material guide structure in the existing device is generally a one-piece material guide plate, and is often in a fixed installation position with the feeding assembly. However, due to the inconsistent height of the crucible body in the furnace body, the longitudinal spacing between the feeding assembly and the feeding port of the crucible body is different, so that there is still a certain falling gap between the material guide plate and the material receiving port of the crucible body, so that there is still a risk of the material falling directly into the furnace body from the gap, so that the material transported by the feeding assembly cannot all enter the crucible body for melting, affecting subsequent processing.

[0004] Therefore, it is necessary to invent a material guiding device for the connecting section in a smelting furnace to solve the above problems. Summary of the Invention

[0005] In order to address the deficiencies of the prior art, the purpose of the present invention is to provide a material guiding device in the connecting section of a smelting furnace, which solves the problem in the prior art that, due to the inconsistent heights of the crucible body in the furnace body, the longitudinal spacing between the feeding assembly and the feeding port of the crucible body is different, resulting in a certain falling gap between the material guide plate and the material receiving port of the crucible body, so that there is still a risk of the material falling directly from the gap into the furnace body, thereby making it impossible for all the material transported by the feeding assembly to enter the crucible body for smelting, affecting subsequent processing.

[0020] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] The utility model provides Figure 1-3The shown material guiding device in the connecting section of a smelting furnace includes a hollow furnace body 1, a side frame plate 3 detachably installed on the left center of the outer peripheral side wall of the furnace body 1, and an inner clamping plate 5 installed on the inner peripheral side wall of the furnace body 1. The center of the inner clamping plate 5 is detachably plugged with a crucible body 7, which longitudinally penetrates the furnace body 1 and extends to the bottom of the outside of the furnace body 1. A feeding assembly 4 for conveying materials is detachably installed in the side frame plate 3. A rotating plate 10 with a lockable rotation angle is rotatably provided on both sides of the feeding assembly 4. A guide plate 12 is connected between the two rotating plates 10. A telescopic frame 16 with controllable telescopic length is rotatably connected on both sides of the inner clamping plate 5. The other end of the telescopic frame 16 is rotatably connected to one end of the side wall of the guide plate 12 away from the rotating plate 10. The feeding assembly 4 can guide the material transported by the feed track into the furnace body 1, and under the guiding action of the guide plate 12, the material is completely conveyed to the feed port of the crucible body 7.

[0022] The ends of the two side walls of the guide plate 12 away from the rotating plate 10 are connected to side connecting columns 18, and the two side walls of the inner clamping plate 5 are connected to side positioning columns 14. The end of the telescopic frame 16 close to the side positioning column 14 is connected to a swivel 15, and the end of the telescopic frame 16 close to the side connecting column 18 is connected to a clamping ring 17. The swivel 15 is detachably rotatable and sleeved on the side positioning column 14, and the side connecting column 18 is detachably rotatable and clamped in the clamping ring 17. In the process of the guide plate 12 rotating with the rotating plate 10, the two ends of the telescopic frame 16 rotate between the side positioning column 14 and the side connecting column 18 respectively, thereby changing the angle of the telescopic frame 16 according to the rotation of the guide plate 12, and supporting the guide plate 12 by changing the telescopic length of the telescopic frame 16, ensuring stable material guiding of the guide plate 12 in the connecting section.

[0023] The two side walls of the feeding assembly 4 located in the furnace body 1 are connected to the side clamping columns 8, and the other end of the side clamping columns 8 is provided with a stud 9. The rotating plate 10 is detachably rotatable and sleeved on the stud 9, and the stud 9 is threadedly sleeved with a nut 11 that can lock the rotation angle of the rotating plate 10. The rotating plate rotates on the side clamping columns 8 of 10, thereby changing the guiding angle of the guide plate 12 in the connecting section. When the guide plate 12 is adjusted to be located above the feed port of the crucible body 7, the nut 11 is rotated to lock the rotation angle of the rotating plate 10 and the side clamping columns 8, thereby fixing the angular position of the guide plate 12 in the connecting section.

[0024] The top surface of the guide plate 12 is provided with a plurality of buffer guide plates 13 that can weaken the impact force of the falling material. Since the guide plate 12 and the feeding assembly 4 have a certain downward inclination angle, and the material has a certain forward inertia under the transportation of the feeding assembly 4, the buffer guide plate 13 can weaken the impact of the material, thereby preventing the material from directly contacting the crucible body 7 with a large impact force between the feed port and the crucible body 7, thereby damaging the crucible body 7.

[0025] A side snap-in 2 is provided in the center of the left side of the thin wall of the furnace body 1, and the installation position of the side frame plate 3 is adapted to the side snap-in 2. On the one hand, the side frame plate 3 can facilitate the installation of the feeding assembly 4, and on the other hand, it is necessary to provide a sealed state for the furnace body 1 after the feeding is completed.

[0026] A cartridge 6 is detachably mounted in the inner clamping plate 5 , and a crucible body 7 is detachably inserted into the cartridge 6 .

[0027] In the present invention, the feeding assembly 4 conveys the material into the furnace body 1. According to the crucible bodies 7 of different heights inserted in the inner card plate 5, the rotation angle between the rotating plate 10 and the feeding assembly 4 is changed, so that the end of the guide plate 12 away from the rotating plate 10 is slightly higher than the feeding port of the crucible body 7. During the process, the two ends of the telescopic frame 16 rotate between the side wall of the inner card plate 5 and the side wall of the guide plate 12, thereby adjusting the angle of the telescopic frame 16, and by changing the telescopic length of the telescopic frame 16, the telescopic frame 16 is able to move away from the guide plate 12 at an appropriate length. The support is provided at one end of the rotating plate 10, so that the guide plate 12 is firmly connected to the feeding assembly 4 and the crucible body 7. In the utility model, the rotation angle of the rotating plate 10 on both sides of the feeding assembly 4 is changed, so that the other end of the guide plate 12 is adjusted to a position slightly higher than the feeding port of the crucible body 7 according to the crucible body 7 of different heights, thereby avoiding a certain falling gap between the guide plate 12 and the crucible body 7, ensuring that the material will not fall into the furnace body 1 when being transported in the connecting section, and ensuring the integrity of the material guiding in the connecting section.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
