Description

Technical Field

[0001] The utility model mainly relates to the technical field of electromagnetic heating, and specifically relates to an electromagnetic heating tube for a magnetic energy oxidation device. Background Technique

[0002] Electromagnetic heating technology is a heating method that converts electrical energy into heat energy using the principle of electromagnetic induction. The basic principle of this technology is to generate eddy currents in a conductor through high-frequency current. The eddy currents are converted into heat energy due to the resistance of the conductor, thereby achieving the purpose of heating. In a magnetic energy oxidation device, an electromagnetic heating tube is required. The material of the electromagnetic heating tube is usually selected from materials with good magnetic conductivity, such as carbon steel, iron, stainless iron, seamless steel pipes, etc. These materials can effectively utilize electromagnetic induction heating to produce good heating effects. On the contrary, materials with poor magnetic conductivity, such as stainless steel, copper, aluminum, etc., are not suitable for use in electromagnetic heating tubes.

[0003] In the electromagnetic heating section of the electromagnetic heating tube, a coil needs to be spirally wound. If the wires are wound too tightly, it will cause an increase in local resistance because the contact points between the wires may increase the resistance, which will result in additional heat loss and reduce the overall efficiency. If the winding is loose and the gap between the coils is large, it will cause a decrease in the inductance value of the coil. The decrease in inductance may affect the working frequency and efficiency of the electromagnetic heater, and may also cause uneven magnetic field distribution, thereby affecting the heating effect. The uneven distribution of the magnetic field may cause the temperature in some areas of the heating tube to be lower than that in other areas. Currently, there is no structure on the heating section to restrain the coil, resulting in easy local coil offset during use and installation, causing uneven distribution between the coils and affecting the heating efficiency. Content of the Utility Model

Specifically, the utility model mainly provides an electromagnetic heating tube for a magnetic energy oxidation device to solve the technical problem that there is no structure on the current heating section to restrain the coil, resulting in easy local coil offset during use and installation, causing uneven distribution between the coils and affecting the heating efficiency as mentioned in the above background technique.

The heat-conducting skeleton is hollow inside and has openings at both ends. A spiral positioning groove is arranged on the outer wall of the heat-conducting skeleton, and a coil is arranged in the spiral positioning groove. The coil is formed by spirally winding a wire.
