Description

Technical Field

[0001] This utility model relates to the field of special metallurgy, and in particular to a sealing door for the cavity of a vacuum induction melting furnace. 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] When melting metal in a vacuum induction furnace, metal needs to be added to the crucible via an upper feeding device. Simultaneously, the temperature of the molten metal in the crucible needs to be measured periodically or intermittently, or the chemical composition of the molten metal needs to be extracted and analyzed. Current technology relies on manual feeding and temperature measurement, lacking a system that can switch between these two operations as needed, leading to decreased efficiency and high labor intensity for workers. 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 separate feeding device for a vacuum induction melting furnace that can switch between feeding and temperature measurement as needed without manual operation.

[0013] To solve the above-mentioned technical problems, the present invention provides a separate top-feeding device for a vacuum induction melting furnace, comprising:

[0014] Mounting bracket 1 is fixed to the top of the vacuum induction melting furnace, and a guide rail 1.1 is formed on its upper part;

[0015] The upper feeding mechanism 2 is arranged on the guide rail 1.1 and can reciprocate along the guide rail 1.1 to align with or disengage from the isolation valve port of the vacuum induction melting furnace cover. It is used to feed materials into the vacuum induction melting furnace.

[0016] Temperature sampling device 3 is arranged on guide rail 1.1. It can reciprocate along guide rail 1.1 and align with or detach from the isolation valve port of the vacuum induction melting furnace cover. It is used for sampling and temperature measurement.

[0017] Preferably, the vacuum induction melting furnace separate feeding device is further improved, and the feeding mechanism 2 includes:

[0018] The first horizontal drive mechanism is arranged on the guide rail 1.1 and is used to drive the feeding pipeline to move horizontally on the guide rail 1.1 to align with or disengage from the isolation valve port of the vacuum induction melting furnace cover.

[0019] The first vertical drive mechanism is arranged on the first horizontal drive mechanism and is used to drive the feeding pipeline to move up and down to connect with or disconnect from the isolation valve port of the vacuum induction melting furnace cover.

[0020] Optionally, the first horizontal drive mechanism can be driven by a motor, and the first vertical drive mechanism can be driven by a pneumatic cylinder or a hydraulic cylinder.

[0021] Preferably, the vacuum induction melting furnace separate feeding device is further improved, and the temperature sampling device 3 includes:

[0022] The second horizontal drive mechanism is arranged on the guide rail 1.1 and is used to drive the temperature measuring and sampling device 3 to move on the guide rail 1.1 to align with or disengage from the isolation valve port of the vacuum induction melting furnace cover.

[0023] The second vertical drive mechanism, which is arranged on the second horizontal drive mechanism, is used to drive the temperature sampling device 3 to move up and down to connect with or disconnect from the isolation valve port of the vacuum induction melting furnace cover.

[0024] Optionally, the second horizontal drive mechanism can be driven by a motor, and the second vertical drive mechanism can be driven by a pneumatic cylinder or a hydraulic cylinder.

[0025] Preferably, the vacuum induction melting furnace separate top feeding device is further improved such that the feeding pipeline port and / or the isolation valve port of the vacuum induction melting furnace cover are formed with a sealing strip.

[0026] Preferably, the vacuum induction melting furnace separate feeding device is further improved such that the connection port of the temperature sampling device 3 and / or the isolation valve port of the vacuum induction melting furnace cover are formed with a sealing strip.

[0027] Preferably, the vacuum induction melting furnace separate feeding device is further improved, and the vacuum induction melting furnace cover isolation valve is connected to the vacuum induction melting furnace through a telescopic pipeline;

[0028] The lifting mechanism 4 is formed on the top of the vacuum induction melting furnace. It is used to raise or lower the furnace cover isolation valve of the vacuum induction melting furnace so that the upper feeding mechanism 2 and the temperature sampling device 3 are connected or disconnected from the furnace cover isolation valve port of the vacuum induction melting furnace.

[0029] Optionally, the lifting mechanism 4 can be driven by either a pneumatic cylinder or a hydraulic cylinder.

[0030] The working principle of this utility model is explained based on the first embodiment of the present invention as follows;

[0031] When feeding is required, the first horizontal drive mechanism is driven by an electrical signal to align the feeding port of the upper feeding mechanism with the isolation valve port of the vacuum induction melting furnace cover. Then, the first vertical drive mechanism is driven by an electrical signal to lower the feeding mechanism until the feeding port and the isolation valve port of the vacuum induction melting furnace cover form a sealed connection, and feeding is performed.

[0032] When feeding is complete or temperature measurement is required, the first vertical drive mechanism is driven by an electrical signal to raise the feeding mechanism and disengage it from the isolation valve of the vacuum induction melting furnace cover. Then, the first horizontal drive mechanism is driven by an electrical signal to disengage the upper feeding mechanism from the isolation valve of the vacuum induction melting furnace cover, making room for the temperature measurement and sampling device.

[0033] The second horizontal drive mechanism is driven by an electrical signal to align the temperature sampling device with the isolation valve port of the vacuum induction melting furnace cover. Then, the second vertical drive mechanism is driven by an electrical signal to lower the temperature sampling device until a sealed connection is formed between the temperature sampling device and the isolation valve port of the vacuum induction melting furnace cover, thus performing sampling or temperature measurement operations.

[0034] This invention effectively solves the problem of switching between feeding and temperature measurement, eliminating the need for manual switching and improving work efficiency.

[0035] Correspondingly, workers are no longer required to approach the vacuum induction melting furnace to switch between feeding and temperature measurement, which indirectly improves safety. Attached Figure Description
