Abstract
The utility model relates to a liquid pipeline electromagnetic induction heating device, including hollow non-metallic material's liquid pipeline, induction coil and metal material's induction heating stick, induction heating stick axial is settled inside the liquid pipeline, the induction coil coiling is in the liquid pipeline surface, and its characterized in that still includes temperature sensor, and temperature sensor fixes on the induction heating stick with induction heating stick direct contact. The temperature sensor is directly inserted into the induction heating rod, so that the contact is tight, the temperature sensor can quickly sense the change of temperature, and the dry burning protection is more sensitive and timely; the induction heating rod is directly contacted with the liquid, so that the heat loss is less, and the heating efficiency is high; the utility model discloses simple structure still has, the manufacturing of being convenient for, low cost saves the advantage of cost.
Description
Technical field
The utility model relates to the fluid pipeline electromagnetic induction heater, the fluid pipeline electromagnetic induction heater with anti-dry function that particularly a kind of efficiency is high.
Background technology
Existing fluid pipeline heating technique, adopting the hollow tubular calandria mostly is heat generating components, and liquid flows through from hollow tubular calandria inner chamber, and the insulated coil support casing is contained in the tubulose calandria outside, and electromagnetic induction coil is wound on the insulated coil support.In order to prevent the dry combustion method phenomenon, mostly temperature sensor is directly to mount or be flush-mounted in tubulose calandria outer surface.But this hollow tubular heat generating components directly contacts with air, and heat scatters and disappears serious, and efficiency is lower.
In order to address the above problem, more existing technical schemes are employed in hollow pipeline set inside eddy-current heating rod, directly contact with liquid, and heat scatters and disappears and significantly reduces, and has improved the heating efficiency.But because heat generating components is transferred to pipe interior, original temperature sensor thermometric lag that is placed in pipeline external surface is serious, and the protection of dry combustion method timely can't be provided.
Summary of the invention
The purpose of utility model is to consider the problems referred to above, and a kind of thermometric is timely, the anti-dry burning device of easy-to-install fluid pipeline electromagnetic induction heater but provide.
The technical scheme of the utility model is: a kind of fluid pipeline electromagnetic induction heater; The eddy-current heating rod that comprises fluid pipeline, induction coil and the metal material of the non-metallic material of hollow; Said eddy-current heating rod axially is placed in fluid pipeline inside, and said induction coil is wound in the fluid pipeline outer surface, it is characterized in that; Also comprise temperature sensor, temperature sensor is fixed on the eddy-current heating rod and directly contacts with the eddy-current heating rod.
The said temperature sensor is inserted on the eddy-current heating rod.
Further, the said temperature sensor is inserted in the set groove of eddy-current heating stick end.
The degree of depth of the groove of described eddy-current heating stick end is greater than 3 millimeters.
Said fluid pipeline both ends are provided with pipe joint respectively, and the temperature-sensing probe of temperature sensor is plugged in the groove of eddy-current heating stick end, and the other end stretches out from the pipe joint of fluid pipeline end, so that be electrically connected with control circuit.
Said temperature sensor is thermistor or temperature controller.
The beneficial effect of the utility model is because temperature sensor directly is inserted in the eddy-current heating rod, contact closely, temperature sensor is the variation of sense temperature fast, the dry combustion method protection is more in time sensitive; The eddy-current heating rod directly contacts with liquid, and heat scatters and disappears few, and the heating efficiency is high; The utility model also has simple in structure, is convenient to manufacture, and is with low cost, cost-effective advantage.
