[0023] like Figure 1 As shown, an explosion-proof rubber sealing ring 22 is provided between the explosion-proof junction box cover 19 and the explosion-proof junction box housing 9.

[0024] like Figure 1 As shown, the junction box mechanism includes a lower junction box 2 and a lower junction box end cover 20.

[0025] like Figure 1 As shown, the metal heating tube mechanism includes several metal heating tube assemblies, which are evenly arranged between the lower wiring box 2 and the upper wiring box 12, and are fixed in the middle by a support plate 16.

[0030] The working principle of this utility model is as follows:

[0031] like Figure 1 and Figure 2 As shown, the parallel variable frequency dual-magnetic heater proposed in this utility model is based on the law of electromagnetic induction and the eddy current heating effect in its core working principle. The following is a detailed explanation of its working principle:

[0032] When the external power supply is connected to the heater through the high-temperature electromagnetic access line 4, the electric energy is first safely introduced through the wiring device in the explosion-proof junction box shell 9, and under the action of the control circuit, the 50Hz alternating voltage is first converted into direct current voltage, and then the control circuit further converts the direct current voltage into high-frequency alternating voltage with a frequency of 5kHz to 35kHz.

[0033] The electromagnetic heater converts the electric energy into high-frequency alternating current through the electromagnetic heating controller, and when the high-temperature electromagnetic line 4 passes through the alternating current, an alternating magnetic field is generated around it. When the metal container containing iron or other good conductive metal (such as the metal heating pipe 1 in this example) is placed in the magnetic field, the surface of the metal container will cut the alternating magnetic force line, thereby generating an alternating current (i.e. eddy current) around the metal heating pipe. The eddy current makes the carriers around the metal heating pipe and the lower junction box move at a high speed in a random manner, and the carriers collide and rub with atoms to generate heat energy, thereby achieving heating of the substance in the container.

[0034] In order to maintain the stability and efficiency of the heating process, the heater is provided with a temperature sensor (installed through the temperature sensor mounting hole 15). The sensor monitors the temperature of the inside of the heater or the medium in real time, and feeds back the signal to the control circuit.

[0035] The above only describes the preferred embodiment of the present application, and is not used to limit the protection scope of the present application.
