[0034] The working principle of this utility model is as follows:

[0035] like Figure 1 and Figure 2 As shown, the skid-mounted horizontal variable frequency electromagnetic heating vacuum furnace provided by this utility model works by combining variable frequency dual-magnetic heating technology with a vacuum insulation environment, achieving a highly efficient and energy-saving heating process. The specific working principle is as follows:

[0036] Power Conversion and High-Frequency Output: Control cabinet 9 incorporates a rectifier circuit and a control circuit. The rectifier circuit first receives the externally input 50 / 60Hz AC voltage and converts it into DC voltage through rectification. Subsequently, the control circuit further converts the DC voltage into a high-frequency voltage, with the frequency range set between 5-35KHz. This high-frequency voltage serves as the main energy supply for the heating furnace, providing stable and efficient power support for the variable frequency dual-magnetic electromagnetic heater 7.

[0037] Variable frequency dual-magnetic electromagnetic heating: The variable frequency dual-magnetic electromagnetic heater 7 is located at the bottom of the heating furnace shell assembly 13. After receiving high-frequency voltage from the control cabinet 9, it generates an alternating magnetic field around the inner and outer shells of the heater 7. The magnetic lines of force generated by the alternating magnetic field cut through the metal inner and outer shells of the heater 7, generating heat and rapidly heating the medium (water, heat transfer oil) inside the heating furnace shell, thus uniformly heating the medium. The medium in the U-shaped heating coil assembly 2 is heated and output 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, achieving precise heating and avoiding energy waste. At the same time, the insulation layer 6 set on the outside of the heating furnace shell 13 effectively reduces heat loss and improves heating efficiency.

[0038] Temperature monitoring and intelligent control: Control cabinet 9 not only handles power conversion but also integrates an intelligent control system. Based on the preset temperature setpoint, the intelligent control system automatically adjusts the output power of the variable frequency dual-magnetic heater 7 to ensure that the heating process is both efficient and energy-saving.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
