Description

Technical Field

[0001] The utility model relates to the technical field of vacuum refining furnaces, in particular to a vacuum refining furnace with good stability. Background Art

[0002] A vacuum refining furnace is a device used for high-temperature treatment of metal materials, usually used to improve the purity and uniformity of materials. This equipment heats, melts, recrystallizes and other processes on metal materials in a vacuum environment to remove impurities, oxides and gases, thereby improving the quality and performance of the materials; a vacuum refining furnace is usually composed of a furnace body, a vacuum system, a heating system and a control system. During operation, the metal material to be processed is first placed in the vacuum refining furnace, and then the air in the furnace is extracted through the vacuum system to form a highly purified vacuum environment. Next, the metal material is heated by the heating system to reach the required temperature. At high temperatures, impurities and oxides will be volatilized or diffused out of the material, thereby achieving the effect of purification.

[0003] The vacuum refining furnace requires a stable working environment during operation. A stable working environment is essential to ensure the quality and efficiency of metal material processing. It ensures that the vacuum system can continuously and stably maintain the required vacuum degree to avoid gas leakage or pressure fluctuations affecting the process. It ensures that the structure of the vacuum refining furnace is stable and reliable, able to withstand the influence of external vibrations and shocks, and ensures that the process operation is not disturbed by the outside world.

[0004] Vacuum refining furnaces require a large degree of reduction in human intervention, as manual operations are easily affected by subjective factors. Automated systems can accurately perform operations according to preset parameters, reduce the production of defective products due to human errors, and avoid gas leaks that affect the stability of the vacuum system.

[0005] The patent with publication number CN206396272U discloses a vacuum refining furnace, including a vacuum chamber cylinder and an ear shaft, an ear shaft seat, a support leg and an alloy chute arranged on the vacuum chamber cylinder, and also includes a fixed platform fixed on the vacuum chamber cylinder for maintenance personnel to stand and a protective railing connected to the fixed platform, wherein an opening for docking with the maintenance platform is opened on the railing, and a movable door movably connected to the railing is installed on the opening, and the opening is opened or closed when the movable door is opened and closed; although the above device solves the safety problem during vacuum chamber maintenance.

[0006] However, the above solution still has problems:

[0007] The existing vacuum refining furnace lacks a supporting structure when in use. The vacuum refining furnace requires a highly stable environment when performing vacuum pumping operations. The lack of a supporting structure cannot guarantee the stability of the vacuum system, which can easily lead to gas leakage and / or pressure fluctuations. In addition, manual intervention in the closing work between the furnace body and the furnace cover is prone to errors, and the execution of the operation cannot be guaranteed. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 3 As shown, a vacuum refining furnace with good stability includes a refining furnace body 1 composed of a furnace body 2 and a furnace cover 3. The furnace body 2 and the furnace cover 3 are arranged in a transverse alignment. A bottom plate 6 is installed at the bottom of the refining furnace body 1. A stabilizing mechanism 4 is installed between the bottom plate 6 and the outer side of the furnace body 2. A sliding device 5 is installed between the outer side of the furnace cover 3 and the bottom plate 6. The sliding device 5 and the bottom plate 6 are slidably connected.

[0023] like Figure 1 As shown, a vacuum refining furnace with good stability in the utility model is similar to the structure of the existing vacuum refining furnace, such as the vacuum refining furnace disclosed in the patent publication number CN206396272U. The main improvement of the utility model is to improve the accuracy of the vacuum tube refining furnace when closing the furnace cover, such as Figures 1 to 3 As shown, when a vacuum refining furnace with good stability in the utility model is in use, metal is placed in the refining furnace body 1, and the sliding device 5 is pushed. The sliding device 5 slides on the surface of the bottom plate 6 to move toward the furnace body 2. The furnace body 2 is fixed to the surface of the bottom plate 6 by the stabilizing mechanism 4. The sliding device 5 drives the furnace cover 3 and the furnace body 2 to gradually close, and a closed space is formed inside the refining furnace body 1. The sliding device 5 replaces the manual closing method of the furnace cover 3, which can reduce the error caused by manual intervention and improve the stability of the refining furnace body 1. When the refining furnace body 1 is performing a vacuum exhaust operation, the stabilizing mechanism 4 fixes the furnace body 2 on the bottom plate 6 to prevent the furnace body 2 from shaking when the furnace body 2 is being exhausted, thereby affecting the exhaust effect, preventing gas leakage or pressure fluctuations, and improving the stability of the operation of the refining furnace body 1 to avoid vibration affecting the process.

[0024] like Figures 1 to 3 As shown, the stabilizing mechanism 4 includes a fixing ring 401, a triangular support frame 402, a fixing bar 403 and a fixing frame 404. A plurality of fixing rings 401 are sleeved on the outer side of the furnace body 2. The two ends of the outer sides of the fixing rings 401 are fixedly connected with the triangular support frames 402. The bottom edge of the triangular support frame 402 is fixedly connected to the surface of the bottom plate 6. The fixing bars 403 are fixedly connected between the plurality of triangular support frames 402. The fixing frame 404 is fixedly connected to the inner wall of the fixing ring 401 located at the bottom of the furnace body 2.

[0025] Specifically, by setting up the fixing ring 401 and the triangular support frame 402, the furnace body 2 is laterally fixed on the bottom plate 6 to prevent it from shaking vertically. The fixing bar 403 provides support between multiple triangular support frames 402, further improving the stability of the stabilizing mechanism 4. The fixing frame 404 provides a lateral anti-slip effect for the furnace body 2, further improving the anti-seismic effect of the stabilizing mechanism 4.

[0026] like Figures 1 to 3 As shown, the inner angle of the triangular support frame 402 is set at 45 degrees.

[0027] Specifically, the stability of the triangular support frame 402 can be improved by setting the inner angle of the triangular support frame 402 at 45 degrees. This angle not only provides good stability, but also averages the force on both sides, and the supporting surface at the inner angle of 45 degrees is the most solid.

[0028] like Figure 3 As shown, the sliding device 5 includes an annular fixing frame 501 and a sliding plate 502 . The annular fixing frame 501 is sleeved on the outer side of the furnace cover 3 , and the sliding plate 502 is fixedly connected to the bottom of the annular fixing frame 501 .

[0029] Specifically, through this arrangement, the furnace cover 3 is fixed to the surface of the bottom plate 6 by the annular fixing frame 501, so that when it is moved horizontally, it always remains aligned with the open part of the furnace body 2. The annular fixing frame 501 also provides a stabilizing effect for the furnace cover 3 when the refining furnace body 1 is performing vacuum extraction and heating, thereby maintaining the overall stability of the refining furnace body 1.

[0030] like Figure 3 As shown, a sliding groove 601 is provided on the surface of the bottom plate 6 and is slidably connected to the sliding plate 502 .

[0031] Specifically, through this arrangement, the furnace cover 3 can be moved on the surface of the bottom plate 6 when closing the furnace body 2 and the furnace cover 3, and the slide groove 601 can avoid affecting the path of the material cart when manually placing the metal material in the refining furnace body 1, thereby improving the work efficiency of the workers.

[0032] like Figure 1 As shown, one end of the furnace cover 3 is fixedly connected to the output end of the driving telescopic rod 7.

[0033] Specifically, through this arrangement, the closing operation of the furnace body 2 and the furnace cover 3 is mechanically automated, reducing the possibility of errors when manually closing the furnace cover 3, improving the accuracy of closing the furnace cover 3, and improving the stability of the vacuum refining furnace.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
