Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides that a kind of energy consumption is little, efficiency is high, insulated enclosure performance is good, it is convenient to control, the life-span is long, can realize automatic temperature-adjusting control and protection, the structure of safer heating in medium frequency rod.
The utility model solves the technical scheme that its technical problem adopts: copper coil (2) is closely wrapped in magnetic core stick (1), be placed in ferromagnetic tubes (4), and and between ferromagnetic tubes (4), fill insulation and thermal insulation layer (3), copper coil (2) is at the bottom position serial connection PTC thermo-sensitive resistor (6) of heating in medium frequency rod, the top of magnetic core stick (1) adopts magnet ring (5) to seal, on magnet ring (5), offer inlet wire and the outlet of two through holes as copper coil (2), the inlet wire of copper coil (2) is connected with outside intermediate frequency power supply through hermetic terminal (7) with outlet.
Magnetic core stick (1) is mainly used to magnetic conduction, reduces the magnetic resistance of whole magnetic circuit, good for ensureing its magnetic property, can not produce amount of heat, and therefore magnetic core stick (1) adopts medium-high frequency magnetic conduction and non electrically conductive material.
Magnet ring (5) is mainly used to magnetic conduction and the top of magnetic core stick (1) is sealed, therefore magnet ring (5) adopts same material with magnetic core stick (1), external diameter is identical with ferromagnetic tubes (4) internal diameter, to reduce the air gap between magnetic core stick (1) and ferromagnetic tubes (4) as far as possible, thereby further reduce the magnetic resistance of whole magnetic circuit, also effectively reduce near the magnetic flux density of hermetic terminal (7) simultaneously, reduce the heating of its near zone, improve seal and life-span.
Hermetic terminal (7) is mainly used to non-calandria to play the effect of protection, and therefore hermetic terminal (7) adopts insulation and thermal insulation material.
Ferromagnetic tubes (4) is mainly as heater, therefore ferromagnetic tubes (4) adopts and had not only conducted electricity but also the ferrimagnet of magnetic conduction, wall thickness is determined according to the kelvin effect effective range under adopted IF-FRE, consider the kelvin effect under intermediate frequency, for making full use of material, tube wall is unsuitable blocked up, is about 1mm left and right, because the most occasions of heating in medium frequency rod are to be immersed in liquid, ferromagnetic tubes (4) need have anti-corrosive properties or outer surface to do preservative treatment.
PTC thermo-sensitive resistor (6) is mainly as automatic temperature-controlled element, and therefore PTC thermo-sensitive resistor (6) need be close to the inner surface of ferromagnetic tubes (4), basic identical to ensure the temperature of itself and heated material; Its operating temperature value, the namely Curie-point temperature value of material, can select according to heating rod purposes.According to PTC thermo-sensitive resistor (6) properties of materials, in the time that temperature exceedes operating value, its resistance increases rapidly; making in wire loop electric current minimum is even 0, and temperature is during lower than operating value, and its resistance can reduce again; thereby realize thermostatic control effect, and play the effect of overtemperature protection.
Compared with prior art, the utlity model has following advantage:
Adopt intermediate frequency magnetic field heating, energy consumption is little, efficiency is high, insulated enclosure performance is good, adopts PTC thermo-sensitive resistor to be connected in coil, can realize automatic temperature-adjusting control and overtemperature protection, controls convenient, life-span length, safer.
