Description
Technical field
The utility model relates to a kind of electric heater unit, relates in particular to a kind of safety electric heating pipe.
Background technology
Electric heating tube generally by metal tube, be arranged on the resistance wire in metal tube and thermal conductivity is good, the crystal magnesium oxide powder of good insulating etc. forms, be applicable to add hot-air, oil, water, chemical mediator, hot-die, fused salt, alkali and low-melting alloy etc.It is slow that the electric heating tube ubiquity using at present firing rate, the problems such as heat transfer efficiency is low, and existing electric heating tube end leads is mixed and disorderly, the overheating of end windings and parts of electric heating tube in the time of work, if the body of the composition of many heating tubes, heating tube body can be at work because the impact that is subject to media flow is shifted, and these reasons all may produce the security incidents such as electric leakage, short circuit.
Utility model content
Utility model object: the purpose of this utility model is that existing electric heater for heating speed is slow, heat transfer efficiency is low, uneasy congruent technical problem in order to solve, and provides a kind of firing rate fast, the safety electric heating pipe that heat transfer efficiency is high and safe.
Technical scheme: a kind of safety electric heating pipe described in the utility model, comprise body, be arranged on the resistance wire in described body and be filled in the magnesia powder in described body, in the end of described body, be connected with mounting flange and binding post in turn, described body is to be arranged and form around the even circumferential of described mounting flange by many onesize U-shaped pipes, between described mounting flange and described binding post, be provided with thermal insulation board, the end of described body is also provided with removable wiring box, one end of described terminal box is provided with water joint, the middle part of described body is provided with spoiler, this spoiler semicircular in shape and have thereon hole intert be fixed on U-shaped pipe body.
Improve further as the utility model, described thermal insulation board is made up of the heat-barrier material in outer cover of steel plate and described outer cover of steel plate, and outer cover of steel plate can ensure the hardness of thermal insulation board.
Improve further as the utility model; in order to detect the temperature regime in whole electric heating tube region; avoid electric heater because local excess temperature damages; described electric heating tube also comprises the temperature element that is arranged on described body inside; the binding post of described temperature element and the binding post of described body are in the same side, and described temperature element is made up of thermocouple and the protective casing being wrapped in outside thermocouple.
Beneficial effect: safety electric heating pipe described in the utility model, U-shaped pipe is that highly dense formula is arranged, compact conformation, firing rate is fast, surperficial power load is large, be the 2-4 of air heat surface loading doubly; Between described mounting flange and described binding post, be provided with thermal insulation board, can prevent the overheating of end windings and parts of heating tube; The setting of detachable terminal box, has avoided causing due to the binding post leaking outside and wire electric leakage the problem of security incident; Because can making heated medium, the setting of spoiler produces turbulent flow, thus even flash heat transfer, and this spoiler has also played the effect of fixing U-shaped pipe, good stability.
