[0031] The working principle of the utility model is as follows:

[0033] Power conversion and high-frequency output: the control cabinet 9 is built-in with a rectifier circuit and a control circuit, the rectifier circuit first receives the external input 50 / 60Hz alternating voltage, and converts it into direct current voltage through rectification. Subsequently, the control circuit further converts the direct current voltage into high-frequency voltage, and the frequency range is set between 5-35KHz. This high-frequency voltage serves as the main energy supply of the heating furnace, and provides stable and efficient power support for the variable-frequency double-magnetic electromagnetic heater 6.

[0034] Variable frequency double magnetic electromagnetic heating: The variable frequency double magnetic electromagnetic heater 6 is located at the bottom of the heating furnace shell assembly 1, and after receiving the high-frequency voltage from the control cabinet 9, an alternating magnetic field is generated around the inner and outer shells of the heater 6. The magnetic lines of force generated by the alternating magnetic field cut the metal inner and outer shells of the heater 6 to generate heat, which rapidly raises the temperature of the medium (water, heat conducting oil) in the heating furnace shell and uniformly heats the medium. The medium in the spiral coil inner and outer assembly 2 is heated in the form of heat exchange. Due to the use of variable frequency technology, the heater can adjust the magnetic field strength and frequency according to actual needs, realize precise heating, and avoid energy waste.

[0035] Heat transfer and vacuum insulation: The heat insulation layer 5 arranged outside the heating furnace shell 101 effectively reduces heat loss and improves heating efficiency. In addition, the inside of the heating furnace is maintained in a vacuum state, which is realized by connecting vacuum valves and other equipment through the vacuum valve interface 3, further reducing heat conduction and convection loss, and ensuring the stability and efficiency of the heating process.

[0036] Temperature monitoring and intelligent control: The control cabinet 9 not only takes charge of power conversion, but also integrates an intelligent control system. Through the temperature sensor interface 102 arranged on the heating furnace shell assembly 1, the system can monitor the overall temperature of the spiral coil inner and outer assembly 2 and the inside of the heating furnace in real time. According to the preset temperature setting value, the intelligent control system automatically adjusts the output power of the variable frequency double magnetic electromagnetic heater 6 to ensure that the heating process is efficient and energy-saving. At the same time, auxiliary interfaces such as the vacuum pressure gauge interface 103 and the thermometer interface 104 also provide important protection for the stable operation of the system.

[0037] Safety maintenance and convenient operation: The heating furnace is also equipped with maintenance interfaces such as blowdown port 105, water replenishment port 12, and exhaust port 13 to facilitate users to carry out regular maintenance and maintenance. The lifting lug 4 on the top plate 10 facilitates the lifting and transportation of the heating furnace. In addition, the design of the magnetic flap liquid level meter interface 106 also improves the automation degree and operation convenience of the heating furnace.

[0038] The above is only a preferred embodiment of the present application, and is not intended to limit the scope of protection of the present application.
