Abstract
The utility model relates to an anticorrosion electric heating device. The electric heating device comprises an electric heating bar made of ordinary silicon carbide heating material, and is characterized in that the electric heating bar is W-shaped and is arranged in a ceramic sleeve; and a sealing cap is arranged at the opening of the ceramic sleeve, and two wiring terminals of the electric heating rod pass through the sealing cap and are fixed outside the sealing cap. The outer surface of the ceramic sleeve is provided with dot-shaped projections which are distributed around the whole ceramic sleeve. According to the utility model, the electric heating bar with such a configuration can effectively solve the problem that the conventional electric bar is corroded if put into a metal plating solution; the ceramic sleeve has high strength, being uneasy to be damaged in use; and the ceramic material has high terminal conductivity, causing low loss of heat. Besides, the dot-shaped projections on the outer surface of the ceramic sleeve can effectively increase the specific surface area of the ceramic sleeve, such that the ceramic sleeve is fully contacted with the metal plating solution, thereby improving the heating efficiency and thermal conductivity of the heating device.
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
Make the diaphragm of metal object surface formation to be plated one deck densification by the method for hot-dip, 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, the general employing of prior art melted heating in the method for pot external heat 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 recent years adopting heat resistant glass or silicon dioxide as the design that adds hot charging rod protective sleeve, its heat resistant glass and silicon dioxide protective sleeve intensity are too low, easily broken, and heat conduction efficiency is not high, has equally the waste of the energy.
Utility model content
In order to solve above-mentioned metal plating liquid inner heating device; its heating rod protective sleeve intensity is low; and the problem that heat conduction efficiency is not high; the invention provides a kind of anticorrosion electric calorifie installation, it comprises the electrical bar of being made up of common carborundum exothermic material, it is characterized in that described electrical bar is " W " type; and be arranged in a porcelain bushing; in described porcelain bushing port, one seal cover is set, and two Wiring ports of described electrical bar are through described seal cover, are fixedly installed on outside seal cover.And described porcelain bushing outer surface is covered with the protruding thorn of pit shape.
The corrosion that can effectively resist metal plating liquid due to porcelain bushing, and have higher compactness, the characteristics such as high strength, therefore, above-mentioned handle " W " type electrical bar is arranged in porcelain bushing, and seal cover is set and makes formation confined space in porcelain bushing, can effectively solve general electrical bar and put into the problem being etched in metal plating liquid, and porcelain bushing intensity is high, is in use difficult for damaged in collision, and ceramic material pyroconductivity is high, and heat-energy losses is few.Meanwhile, Wiring port is set through seal cover being fixed on seal cover, and Wiring port is the threaded rod structure with nut, this kind of setting can make electrical bar be inserted in after porcelain bushing, still can facilitate wiring external power, controls the switch of electrical bar.
And, porcelain bushing outer surface is set and is covered with the protruding thorn of pit shape, can effectively increase the specific area of porcelain bushing, porcelain bushing is fully contacted with metal plating liquid, improve the efficiency of heating surface of heater, with thermal energy conduction rate.
Through the interface of seal cover, high temperature resistant enamel sealing gasket is set at electrical bar Wiring port, can effectively prevents that porcelain bushing internal heat energy runs off from gap, cause the waste of the energy.
The anticorrosion electric calorifie installation that the utility model provides, can effectively prevent that hot-dip inner heating device is etched in high-temperature metal plating solution, the problem that life-span is short, and wiring, installation, convenient disassembly, and it is nearly 30% that the heat energy propagation efficiency between metal plating liquid significantly improves, and thermal energy conduction rate also has obvious lifting.
Accompanying drawing explanation
The structural representation of the anticorrosion electric calorifie installation 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 electric calorifie installation that the utility model provides, comprise " W " type electrical bar 1 of being made by common carborundum exothermic material, and a porcelain bushing 2 is set, electrical bar 1 is inserted in this porcelain bushing 2, and a seal cover 3 is set in the port of porcelain bushing 2, with this, at the interior formation confined space of porcelain bushing 2, play the effect of protecting electrical bar 1 completely, and two Wiring ports 4 of described electrical bar 1 are through described seal cover 3, and be fixedly installed on outside seal cover 3, Wiring port 4 is arranged to the threaded rod structure with nut simultaneously, can make electrical bar 1 under the protection of porcelain bushing 2, still can conveniently access external power supply.Meanwhile, in order to guarantee the seal in porcelain bushing 2, prevent that heat energy runs off from the seal cover 3 of port, the interface at Wiring port 4 through seal cover 3, arranges high temperature resistant enamel sealing gasket 5, has effectively prevented the loss of heat energy, has improved thermal energy conduction rate.And, in order to increase the contact area of porcelain bushing 2 and metal plating liquid to be heated, the protruding thorn 6 of pit shape is set on porcelain bushing 2, be covered with whole porcelain bushing 2, the specific area that has effectively increased porcelain bushing 2 reaches nearly 30% left and right, thereby has effectively improved the heat transfer efficiency of porcelain bushing 2 to metal plating liquid.In order to facilitate the fixing of this heater, at least 2 alignment pins 7 are set on seal cover 3 simultaneously.
Take galvanizing by dipping as example, first zinc pot is fused into galvanizing flux by zinc ingot metal by the mode of external heat, afterwards this heater is inserted in galvanizing flux, and by the alignment pin 7 arranging on seal cover 3, this anticorrosion heater is fixed on zinc pot, external power supply is connected on the Wiring port 4 of heating rod, start electrical bar 1, heat energy is progressively delivered on the high porcelain bushing of thermal conductivity 2 by electrical bar 1, and be delivered in metal plating liquid by porcelain bushing 2, metal plating liquid is carried out to continual and steady interior heating.
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.
