Description

Technical Field

[0001] This utility model relates to the field of special metallurgy, and in particular to a camera device for viewing a vacuum induction furnace window. Background Technology

[0002] A vacuum induction melting furnace (VIM) is a device that melts metals using electromagnetic induction heating under vacuum conditions. It is widely used in the production of high-quality alloys, especially in aerospace, medical, automotive, and nuclear industries. The VIM uses medium-frequency induction heating technology, generating heat in a conductive material through an alternating electromagnetic field, thereby melting the metal. An induction coil surrounds a crucible containing the metal to be melted. When an alternating current passes through the coil, induced eddy currents are generated in the metal, rapidly heating it and melting it.

[0003] The vacuum induction melting furnace mainly consists of the following components;

[0004] Furnace body: Provides a sealed vacuum environment and is typically made of materials that are resistant to high temperatures and maintain vacuum integrity.

[0005] Medium frequency power supply: Provides the power required for induction heating, including power supply, transformer and control circuit.

[0006] Vacuum system: Composed of vacuum pump, vacuum gauge and valves, responsible for creating and maintaining a vacuum environment.

[0007] Cooling system: Typically uses water cooling channels and fans to prevent overheating.

[0008] Electrical control system: monitors and controls temperature, vacuum level and input power.

[0009] The operating pressure of a vacuum induction melting furnace (VIM) is typically related to its design and operating conditions, referring to GB / T10067.35-2015 "Basic Technical Conditions for Electric Heating Devices Part 35: Medium Frequency Vacuum Induction Melting Furnaces". It is important to note that the operating pressure and operating conditions of the vacuum induction melting furnace must strictly adhere to relevant safety standards and operating procedures to ensure the safety of equipment and personnel. The vacuum level requirement of the vacuum induction melting furnace is a key factor in ensuring the smooth progress of the melting process and obtaining high-quality molten metal. According to JB / T 10551-2006 "Vacuum Technology - Vacuum Induction Melting Furnaces", the vacuum level of a vacuum induction melting furnace generally needs to reach and be maintained within a certain range to meet the melting requirements of different metallic materials.

[0010] Since the melting process in a vacuum induction furnace takes place within a sealed cavity, real-time monitoring of the internal conditions requires a video surveillance system through an observation window. This system is typically mounted on the furnace cover or the side of the mold chamber. The camera captures the furnace's internal workings through the viewing window; however, because the window is made of glass, reflections from external light can affect the observation and recording quality. Utility Model Content

[0011] The utility model description section introduces a series of simplified concepts, all of which are simplifications of existing technologies in the field, and will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0012] The technical problem to be solved by this utility model is to provide a vacuum induction furnace window camera device that can prevent external light from reflecting off the window and affecting the observation effect.

[0013] To solve the above-mentioned technical problems, the present invention provides a vacuum induction furnace viewing window camera device, which is installed on the observation tube of the vacuum induction furnace, comprising:

[0014] The shielding element 2 is arranged on the observation tube 1 and can extend into the observation tube 1 to shield the observation tube 1. It is used to prevent dust or impurities generated by the vacuum induction furnace melting from adhering to the viewing window 3 and affecting observation. During non-observation stages, it shields the observation tube 1.

[0015] Viewing window 3 is formed at the top of observation tube 1;

[0016] The light-shielding housing 4 is fixedly mounted on the window 3 and is used to prevent external light from reflecting off the window 3;

[0017] Camera 5 is housed in the light-shielding housing 4;

[0018] A gas cooling device 6 is arranged on the top of the light-shielding housing 4. It fills the light-shielding housing 4 with flowing gas to form a vortex for cooling and / or fills the light-shielding housing 4 with low-temperature gas for cooling.

[0019] Alternatively, the vacuum induction furnace viewing window camera device can be further improved, with the shielding element 2 being a slide valve.

[0020] Alternatively, the vacuum induction furnace viewing window camera device can be further improved, with the slide valve fixed to one side of the observation pipeline 1 via a flange.

[0021] Alternatively, the vacuum induction furnace viewing window camera device may be further improved by including an adjustable universal bracket 7, which is fixed inside the light-shielding housing 4 and is used to support the camera 5.

[0022] Alternatively, further improvements to the vacuum induction furnace viewing window camera device may include:

[0023] The flip cover 8 is formed on any inner wall of the light-shielding housing 4, except for the inner wall on which the adjustable universal bracket 7 is mounted.

[0024] Optionally, the vacuum induction furnace viewing window camera device can be further improved, and the gas cooling device 6 can be a vortex tube;

[0025] The light-shielding housing 4 is a non-sealed housing.

[0026] Optionally, the vacuum induction furnace viewing window camera device can be further improved, and the gas cooling device 6 is a gas supply pipe for introducing cooling gas.

[0027] At least one vent is formed on the light-shielding housing 4.

[0028] Alternatively, the vacuum induction furnace viewing window camera device may be further improved, with the cooling gas being cryogenic air, cryogenic nitrogen, or cryogenic carbon dioxide.

[0029] The working principle and technical effects of this utility model are as follows;

[0030] To prevent external light from reflecting off the viewing window and affecting image quality, this invention features a light-shielding housing to block external light from reaching the window. However, the large amount of radiant heat generated during metal smelting in the furnace heats the air inside the light-shielding housing through the viewing window, causing a significant temperature increase that severely impacts the camera's operation and shortens its lifespan. Therefore, this invention incorporates a gas cooling device to cool the air inside the light-shielding housing, thus solving the external light problem while preventing the light-shielding housing from negatively affecting the camera's lifespan.
