Abstract
The utility model provides an anti-corrosion resistance wire heating rod, which comprises a metal bushing, a ceramic insulator and a resistance wire both arranged inside the metal bushing. The heating rod is characterized in that the outer surface of the metal bushing is coated with an enamel coating layer. The entire body of the ceramic insulator is provided with a spiral groove. The resistance wire is wound inside the groove. According to the technical scheme of the utility model, when applied in a to-be-heated metal plating solution during the metal hot dipping process, the heating rod is soaked in metal plating solution to heat the metal plating solution. Meanwhile, the enamel coating layer is resistant to the corrosion of the high-temperature metal plating solution and excellent in compactness. The atmosphere is also prevented from being corroded by the metal plating solution at the same time. In addition, the heating rod is high in strength and resistant to thermal shock. Therefore, the resistance wire heating rod provided by the utility model is longer in operating time, shockproof and anti-stubbing.
Description
Technical field
The utility model relates to corrosion and protection field of engineering technology, relates in particular to heating anticorrosion field in metal hot dipping plating solution.
Background technology
By the method for hot-dip, make the diaphragm of metal object surface formation to be plated one deck densification, can effectively improve the corrosion resistance of object surface to be plated.At present, technology comparative maturity have galvanizing by dipping, hot-dip aluminizing, hot dipping of zinc-aluminum alloy etc., first all need first feed metal (zinc or aluminium) to be heated in pot fusing point, just can carry out subsequent thermal immersion plating after being fused into metal plating liquid.At present, prior art is general adopts the method at pot external heat to melt heating to metal plating liquid, and the method is because first thermal source passes to heating kettle, and heating kettle passes to inner metal plating liquid again, therefore has larger thermal loss, causes the waste of the energy.Although and the method and internal heating energy utilization rate that employing is directly heated metal plating liquid in pot is high, exist the heater being immersed in metal plating liquid there is no the problems such as good decay resistance.Although occurred that employing heat resistant glass or silicon dioxide are as the design of heater protective sleeve recent years, its heat resistant glass and silicon dioxide protective sleeve intensity are too low, easily broken; And adopting general ceramic protective sleeve, its shaking property of heat resistanceheat resistant is poor, easily burst, and its pyroconductivity is not high; And adopt metal sleeve surface spraying ceramic coating as protective sleeve; although can prevent the erosion of metal plating liquid to heater; but because ceramic coating compactness is not high; there is certain space; therefore; can not prevent the erosion of aggressive atmosphere to heater metal sleeve, be greatly limited useful life.
Utility model content
In order to solve in above-mentioned metal plating liquid, heat; its heater protective sleeve cannot meet and have some strength simultaneously; and can resistance to metal plating liquid and plating solution atmosphere corrosion and the high problem of shaking property of heat resistanceheat resistant; the invention provides a kind of anticorrosion Resistant heating rod; it comprises metal sleeve; and at inner ceramics insulator and the resistance wire arranging of metal sleeve, it is characterized in that described metal sleeve outer surface is coated with enamel coating.
Because enamel coating possesses refractory metal bath corrosion, and compactness is good, can prevent the corrosion of metal plating liquid corrosive environment simultaneously, and there is higher intensity and the heat resistanceheat resistant performance of shaking, therefore, the utility model adopts enamel coating as the outer jointing jacket of metal sleeve in heater, can effectively prevent the corrosion of high-temperature metal plating solution and high temperature plating solution atmosphere, working life increases greatly, and in routine use process, not fragile, and can coordinate heating kettle external heating device to use simultaneously, can not cause greatly the damage of this heating rod because of difference variation.
And the anticorrosion Resistant heating rod that the utility model provides, is provided with helical groove in the ceramics insulator entire body of portion within it, its resistance wire is wound around and is arranged in described groove.
This kind setting can effectively prevent that the vibrations in the course of the work of this heating rod from causing resistance wire to channel bit, and causes the phenomenon of short circuit, has improved useful life and the fail safe of Resistant heating rod.
Accompanying drawing explanation
The structural representation of the anticorrosion Resistant heating rod that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, the anticorrosion Resistant heating rod that the utility model provides, comprise metal sleeve 1, and the enamel coating 2 that adopts enamel technology to apply at metal sleeve 1 outer surface, at the inner ceramics insulator 3 arranging of metal sleeve 1, and the spiral groove 5 arranging in the entire body of ceramics insulator 3, and resistance wire 4 windings are arranged in groove 5.The metal sleeve 1 of this Resistant heating rod adopts common steel tube, stainless steel tube or heat resisting pipe; the enamel coating 2 of its outer surface adopts common enamel technology to apply; sintering one deck oxide frit for porcelain enamel, at the enamel protective layer of metal sleeve 1 outer surface formation one deck densification.This anticorrosion Resistant heating rod is put in heating kettle metal plating liquid is heated, under the effect of Resistant heating, metal plating liquid remains liquid state, the enamel coating of its outer surface has effectively prevented the corrosion of metal plating liquid and plating solution atmosphere, and intensity is high, thermal shock resistance is good.
Above-mentioned is only basic principle of the present utility model, any restriction of not the utility model being made, and every equivalent variations of it being carried out according to the utility model and modification, all within protection range of the present utility model.
Claims (2)
