Description

Technical Field

[0001] This utility model relates to the technical field of electric arc smelting equipment, and particularly to vacuum electric arc smelting equipment. Background Technology

[0002] Vacuum arc smelting equipment is a device that uses the high temperature generated by electric arc discharge in a vacuum environment to melt and refine metals. It is widely used in the smelting and purification of special metal materials (such as titanium, zirconium, tantalum, niobium, etc.). Existing vacuum arc smelting equipment has at least the following drawbacks during use: 1. The observation window of the existing vacuum arc smelting equipment is easily contaminated with dust during use, which affects the use of the observation window; 2. Existing vacuum arc smelting equipment generates strong electromagnetic radiation and thermal radiation during use. Existing smelting equipment lacks protective measures, which affects the health of operators and the normal operation of surrounding equipment. Therefore, we have introduced a vacuum arc smelting equipment. Utility Model Content

[0003] The main purpose of this invention is to provide a vacuum arc smelting apparatus, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A vacuum arc smelting apparatus includes an arc smelting furnace. A first protective device is movably connected to the upper right side of the arc smelting furnace, and a second protective device is movably connected to the upper left side of the arc smelting furnace. The second protective device has the same structure as the first protective device. Support legs are fixedly connected to the four corners of the lower end of the arc smelting furnace. An observation port is provided on the arc smelting furnace, and a dustproof device is fixedly connected to the outer surface of the observation port.

[0006] Preferably, the dustproof device includes a cover plate, a handle fixedly connected to the left side of the outer surface of the cover plate, the handle having a "U" shaped structure, an observation window provided in the middle of the front end of the cover plate, a first connecting part fixedly connected to the right side of the outer surface of the cover plate, the right end of the first connecting part having an arc-shaped structure, a connecting shaft fixedly connected to the front end of the first connecting part, and a second connecting part movably connected to the rear side of the outer surface of the connecting shaft via a bearing, the right end of the second connecting part having an arc-shaped structure.

[0007] Preferably, the second connecting part is fixedly connected to the outer surface of the observation port, and the cover plate is located in front of the observation port.

[0008] Preferably, scraper strips are fixedly connected to the upper and lower rear ends of the cover plate, and a cylinder is movably connected to the upper end of the cover plate via a bearing, with a limiting member fixedly connected to the outer surface of the cylinder.

[0009] By adopting the above technical solution: the limiting component can rotate freely, and when it rotates to the rear, the limiting component can limit the cover plate, preventing the cover plate from falling naturally without being limited.

[0010] Preferably, both of the scrapers are in contact with the front end of the observation port.

[0011] Preferably, the first protective device includes a protective frame, a first slot is opened at the upper right end of the protective frame, a hinge is fixedly connected at the lower right end of the protective frame, and a second slot is opened at the upper left end of the protective frame.

[0012] Preferably, the protective frame is movably connected to the electric arc smelting furnace via two hinges.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by setting a dustproof device, the second connecting part is connected to the outer surface of the observation port, and the second connecting part is connected to the first connecting part on the outer surface of the cover plate through a connecting shaft, so that the cover plate can be freely adjusted in angle. The cover plate can protect the observation port and prevent dust accumulation. When there is dust on the observation port, the angle of the cover plate can be adjusted back and forth to allow the two scrapers at the rear end of the cover plate to clean the observation port, which improves the convenience of use.

[0015] 2. In this utility model, by setting up a first protective device and a second protective device, since the protective frame is movably connected to the electric arc smelting furnace through two hinges, by moving the protective frames of the first and second protective devices, the angle of the two protective frames can be adjusted to jointly shield the furnace body. The protective frame is made of lead plate material, which can effectively block the strong electromagnetic radiation and heat radiation generated by the electric arc, protect the health of the operators and the normal operation of the surrounding equipment.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] The vacuum arc smelting apparatus includes an arc smelting furnace 1. A first protective device 2 is movably connected to the upper right side of the arc smelting furnace 1, and a second protective device 5 is movably connected to the upper left side of the arc smelting furnace 1. The second protective device 5 and the first protective device 2 have the same structure. Support legs 6 are fixedly connected to the four corners of the lower end of the arc smelting furnace 1. An observation port 3 is provided on the arc smelting furnace 1, and a dustproof device 4 is fixedly connected to the outer surface of the observation port 3.

[0026] In this embodiment, the dustproof device 4 includes a cover plate 41. A handle 46 is fixedly connected to the left side of the outer surface of the cover plate 41. The handle 46 has a "U" shaped structure. An observation window 45 is provided in the middle of the front end of the cover plate 41. A first connecting part 42 is fixedly connected to the right side of the outer surface of the cover plate 41. The right end of the first connecting part 42 has an arc surface structure. A connecting shaft 44 is fixedly connected to the front end of the first connecting part 42. A second connecting part 43 is movably connected to the rear side of the outer surface of the connecting shaft 44 through a bearing. The right end of the second connecting part 43 has an arc surface structure. The second connecting part 43 is fixedly connected to the outer surface of the observation port 3. The cover plate 41 is located in front of the observation port 3. Scraper strips 413 are fixedly connected to the upper and lower rear ends of the cover plate 41. A cylinder 411 is movably connected to the upper end of the cover plate 41 through a bearing. A limit member 412 is fixedly connected to the outer surface of the cylinder 411. Both scraper strips 413 are in contact with the front end of the observation port 3.

[0027] Through the above solution: the cover plate 41 performs its protective function, providing all-round protection for the observation port 3, effectively preventing dust from accumulating on the surface of the observation port 3, ensuring the clarity and normal use of the observation port 3. When the observation port 3 inevitably gets dusty, the two scrapers 413 at the rear end of the cover plate 41 will quickly come into play by simply adjusting the angle of the cover plate 41. During the adjustment of the angle of the cover plate 41, it can closely fit the surface of the observation port 3 and efficiently clean the observation port 3.

[0028] In this embodiment, the first protective device 2 includes a protective frame 21, a first slot 22 is opened at the upper right end of the protective frame 21, a hinge 23 is fixedly connected at the lower right end of the protective frame 21, and a second slot 24 is opened at the upper left end of the protective frame 21; the protective frame 21 is movably connected to the electric arc smelting furnace 1 through two hinges 23.

[0029] The above solution involves adjusting the angle of the protective frame 21, which is located on the outside of the furnace body. The protective frame 21 is made of lead plate, which can effectively block the strong electromagnetic radiation and thermal radiation generated by the electric arc.

[0030] It should be noted that this utility model describes a vacuum arc smelting apparatus. The second connecting part 43 is connected to the outer surface of the observation port 3. The second connecting part 43 is cleverly connected to the outer surface of the cover plate 41 by means of the connecting shaft 44, so that the cover plate 41 has a flexible angle adjustment capability. The operator can easily adjust the cover plate 41 to a suitable angle according to actual needs. The cover plate 41 performs its protective function, providing all-round protection for the observation port 3, effectively preventing dust from accumulating on the surface of the observation port 3, and ensuring the clarity and normal use of the observation port 3. When the observation port 3 inevitably gets dusty, the two scrapers 413 at the rear end of the cover plate 41 will quickly play their role by simply adjusting the angle of the cover plate 41. During the angle adjustment process, the cover plate 41 can closely fit the surface of the observation port 3. The system efficiently cleans the observation port 3, removing dust and impurities, greatly improving ease of use and efficiency. Operators can easily move the protective frames 21 of the first protective device 2 and the second protective device 5. These two protective frames 21, like flexible wings, can be precisely adjusted in angle as needed. When they work together to tightly shield the furnace body, they form a solid protective barrier. The protective frames 21 are made of lead plate, which can effectively block the strong electromagnetic radiation and thermal radiation generated by the electric arc. It's like putting an invisible protective suit on the operators and surrounding equipment, protecting the health of the operators in all aspects and avoiding radiation damage. At the same time, it ensures that the surrounding equipment operates normally in a stable electromagnetic and thermal environment, extending the service life of the equipment and ensuring the safety and reliability of the entire system.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
