Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a crucible bracket structure for a rare earth smelting and melting furnace. Background Technique

[0002] A rare earth melting furnace refers to a device that heats rare earth ores, concentrates or other rare earth raw materials to a high temperature to melt them into a liquid state. During the smelting process, the crucible provides a closed container for rare earth raw materials and other materials to be melted, ensuring that the materials will not leak or scatter during the high-temperature melting process. And the crucible bracket of the melting furnace plays a crucial role during the melting process. In an environment of high temperature and mechanical vibration, a stable crucible position is crucial for ensuring the uniformity and safety of melting. However, the current bracket is not convenient to adjust according to the size of the crucible. When it is necessary to support a larger or smaller crucible, the bracket needs to be replaced;

[0003] To solve the above problems, the prior art has proposed a crucible bracket for an electron beam melting furnace with a patent publication number of CN215983921U. It is provided with a driving mechanism and two lifting mechanisms. The tops of the two lifting mechanisms are respectively connected to two support plates. The driving mechanism can drive the two lifting mechanisms to approach or separate from each other, and then cooperate with the two lifting mechanisms to drive the lifting of the two support plates, so that the two support plates can support crucibles of different sizes. Although it is convenient to support crucibles of different sizes, it only supports and clamps through two support plates during support, and the support plates drive the support seats to move through screws. Although the screw has a certain self-locking property, during the process of rare earth smelting in the melting furnace, the crucible will generate a certain vibration, and the support seat will have a slight displacement on the screw due to the vibration, which will cause the support plate to move slightly, and thus reduce the stability during the support of the crucible.

DETAILED DESCRIPTION OF THE EMBODIMENTS

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

[0034] Please refer to Figures 1 to 4, A crucible support structure for a rare earth smelting furnace, installed inside a smelting furnace for rare earth smelting, includes a bottom plate 1, support plates 2, support bars 3, brackets 4, and a support ring 5. The bottom plate 1 is installed inside the smelting furnace. The support plates 2 are arranged on the upper side of the bottom plate 1 through a support assembly for lifting and lowering. And a support groove for supporting the crucible is provided at the top end of the support plate 2, which can stably support the crucible. There are two support bars 3. The two support bars 3 are arranged to slide towards each other on the top end of the bottom plate 1. A limit block 14 is fixedly connected to the bottom end of the support bar 3. A limit groove for the limit block 14 to slide is provided on the bottom plate 1. Through the cooperation of the limit block 14 and the limit groove, the sliding of the support bar 3 on the bottom plate 1 can be limited, so as to increase the stability of the support bar 3 sliding on the bottom plate 1. The brackets 4 are fixedly connected to each support bar 3. The support ring 5 is fixedly connected to one side of each bracket 4. Support openings for supporting the crucible are provided on the sides of the two support rings 5 that are close to each other. And anti-slip pads 17 are fixedly connected to both support rings 5, which is convenient for stably clamping and supporting the crucible. Positioning frames 15 are fixedly connected to both support rings 5. Elastic pads 16 are fixedly connected to the top ends of the two positioning frames 15. Through the elastic pads 16, crucibles of different specifications can be stably contacted, so as to support the crucible again, thereby improving the stability of supporting the crucible.

[0035] Reference Figure 2 , The support assembly includes a support box 6, an electric cylinder 7, a connecting plate 8, a connecting cylinder 9, and a connecting rod 10. The support box 6 is located on the upper side of the bottom plate 1. The electric cylinder 7 is installed inside the support box 6, and the output end of the electric cylinder 7 is fixedly connected to the support plate 2. There are two connecting plates 8. The two connecting plates 8 are symmetrically connected to both sides of the bottom plate 1. The connecting cylinder 9 is fixedly connected to the top end of each connecting plate 8. The connecting rod 10 is slidably connected through each connecting cylinder 9, and the connecting rod 10 is fixedly connected to the bottom end of the support plate 2. A connecting strip 13 is connected through the connecting rod 10. A connecting groove for the connecting strip 13 to slide is provided on the connecting cylinder 9, which can make the connecting rod 10 move stably inside the connecting cylinder 9;

[0036] When the support plate 2 is in a lower position, the crucible can be carried onto the support plate 2. At the same time, by pushing the support plate 2 through the electric cylinder 7, the support plate 2 can drive the crucible to move, so as to adjust the position of the crucible in the smelting furnace, thereby facilitating the smelting of rare earth in the smelting furnace. At the same time, during the movement of the support plate 2, the two connecting rods 10 will move inside the two connecting cylinders 9 respectively, so as to increase the smoothness of the support plate 2 supporting and moving the crucible.

[0037] Reference Figure 2 , A support frame 11 is fixedly connected to the top end of the bottom plate 1. A double-headed electric cylinder 12 is installed inside the support frame 11. Both support bars 3 are fixedly connected to the output ends of the double-headed electric cylinder 12;

[0038] By pushing the two support bars 3 towards each other through the double-headed electric cylinder 12, the two support bars 3 can drive the two brackets 4 to move towards each other, so that the two brackets 4 can drive the two support rings 5 to move towards each other, thereby enabling the two support rings 5 and the two anti-slip pads 17 to stably clamp and support the crucible.

[0039] In summary, after placing the rare earth to be smelted in the crucible, place the crucible on the support plate 2 and start the electric cylinder 7 to make the electric cylinder 7 push the support plate 2, so that the support plate 2 drives the crucible to move. When the crucible moves to the appropriate smelting position, start the double-headed electric cylinder 12 to make the double-headed electric cylinder 12 drive the two support bars 3 to move towards each other, so that the two support bars 3 drive the two brackets 4 to move towards each other, thereby enabling the two brackets 4 to drive the two support rings 5 to stably clamp and support the crucible. At the same time, when the support ring 5 approaches the crucible, the positioning frame 15 will drive the elastic pad 16 to move closer to the crucible to facilitate the stable support of the crucible, thereby improving the stability of rare earth smelting.
