Abstract
The invention discloses an electric heating tube which comprises a tubular shell, end sockets, a resistance wire and crystal magnesia powder. The end sockets are arranged on the two sides of the shell and used for sealing the ends of the shell, the resistance wire is arranged in the shell and used for heating, the crystal magnesia powder is arranged in the gap of the shell and the resistance wire to be used for heat conduction and insulation, and the outer surface of the shell is provided with an antirust coating. The electric heating tube is characterized in that a far-infrared radiating coating is arranged on the outer surface of the antirust coating, a waterproof layer is arranged on the connecting portion of a sealing opening and the shell, and a quartz sand layer is further sprayed between the antirust coating and the far-infrared radiating coating. The electric heating tube has the advantages of being reasonable in structure, good in using effect and long in service life.
Description
Technical field
The present invention relates to a kind of electric heating tube, belong to a kind of electric heater unit.
Background technology
Electric heating tube is that a kind of use is widely used in the firing equipment that adds hot-air, oil, water, chemical mediator etc.The antirust coat that the heating tube using at present mainly comprises tube body, is arranged on the resistance wire of tube body inside and is arranged on tube body surface, but can there is the phenomenon that antirust coat comes off after long-time use, cause reduce the useful life of heating tube, in serious situation, can there are electrothermal tube corrosion fracture, the major safety risks such as electric leakage.In addition, because the environment for use of electric heating tube is more severe, sometimes need long period of soaking in having the water of temperature, because the magnesium oxide in tube body has moisture absorption function, moisture is too much easily penetrated into electrothermal tube inside, causes heating wire short circuit, and impact is normally used.Therefore, should provide a kind of new technical scheme to address the above problem.
Summary of the invention
The object of the invention is: for above-mentioned deficiency, provide a kind of rational in infrastructure, result of use good, the electric heating tube of long service life.
For achieving the above object, the technical solution used in the present invention is:
A kind of electric heating tube, comprise tubulose housing, be located at housing both sides for end socket that shell end is sealed, be located at enclosure interior be used for heating resistance wire and be located at housing and place, resistance wire gap is used for the crystal magnesium oxide powder of heat conduction and insulation, the outer surface of described housing is provided with antirust coat, the outer surface of described antirust coat is provided with far infrared radiation coating, the junction of described sealing and housing is provided with watertight composition, and between described antirust coat and far infrared radiation coating, also one deck quartz sand layer is established in spray.
Related content in technique scheme is explained as follows:
1,, in such scheme, described watertight composition is the mixture of sodium metasilicate, calcium carbonate.
2,, in such scheme, the end of described end socket and housing is welded in one.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1, because the present invention is provided with far infrared radiation coating at the outer surface of antirust coat, it has good heat-radiating properties, can better improve conductivity of heat and the thermal radiation of electric heating tube.
2,, because the present invention is provided with watertight composition in the junction of end socket and housing, it can be avoided aqueous vapor to infiltrate and cause electrothermal tube electric leakage, safe.
3,, because the present invention is also sprayed and established one deck quartz sand layer between antirust coat and far infrared radiation coating, the surface area that it can increase heating tube, strengthens heat-sinking capability.
Accompanying drawing explanation
Accompanying drawing 1 is the embodiment of the present invention one structural representation;
In above accompanying drawing: 1, housing; 2, end socket; 3, resistance wire; 4, crystal magnesium oxide powder; 5, antirust coat; 6, far infrared radiation coating; 7, watertight composition; 8, quartz sand layer.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
