Abstract
The utility model discloses a novel heating tube. The novel heating tube comprises a tube body and a heating coil arranged inside the tube body, the tube body is also internally provided with an insulating core rod, the heating filament is wound on the insulating core rod and is electrically connected with a ceramic plug through an electric wire that penetrates through the insulating core rod, the ceramic plug is in sealing connection with the tube body, and in addition, magnesia powder is filled between the tube body and the heating coil. The novel heating tube is resistant to high temperature, prevents leakage and has a relatively long service life.
Description
Technical field
The utility model relates to heat-generating pipe field, relates in particular to a kind of plug-type Noval exothermic tube.
Background technology
Electric heating element heat-generating pipe is generally under the condition in dry combustion method, and by air or directly contact with heat-generating pipe appearance and carry out heat and conduct, electric lead generally adopts silica gel line or resistant to elevated temperatures single, mica line etc., and the use of power line is its technological difficulties.
In heat-generating pipe when work,, temperature is very high, and electric lead is for a long time under the condition in high temperature, and sometimes heat-generating pipe is also in mobile status, and therefore, electric lead is very easily oxidized, aging and wearing and tearing, and the heat-generating pipe life-span reduces because of the aging of electric lead.
In current heat-generating pipe manufacturing process, just simply magnesia powder is filled in heat-generating pipe, at the exposed magnesia powder of seal location, though also there is part heat-generating pipe to seal at single silica gel, ceramic glue, pottery for nozzle position, but in the time there is water, wet goods fluid conductors or semiconductor in the operational environment of heat-generating pipe, these conductors or semiconductor will infilter in heat-generating pipe, cause the problems such as heat-generating pipe short circuit, damage, cause the useful life of heat-generating pipe extremely short.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of high temperature resistant, antiseep, the heat-generating pipe of longer service life.
For achieving the above object, the utility model adopts following technical scheme:
A kind of Noval exothermic tube, comprise body and be placed in the heating wire in body, in described body, be also provided with insulation mandrel, described heating wire is wound on insulation mandrel, and be electrically connected with ceramic plug via the electric lead passing in insulation mandrel, described ceramic plug and described body are tightly connected, and, between described body and heating wire, be also filled with magnesia powder.
Further, it also comprises that adapter sleeve is located at the stainless steel pipe box on body, described ceramic plug and stainless steel pipe box sealed engagement.
Further, described ceramic plug is provided with the pin public affairs of colding pressing, described in female male the matching of the pin of colding pressing with on ceramic socket of pin of colding pressing.
Further, described insulation mandrel is magnesium oxide rod.
Further, described ceramic plug is connected with body one end, and the described body other end is filled with solid insulation.
Further, on described ceramic socket, be enclosed with high-temperature insulation composite plate.
Further, described electric lead adopts pure nickel line.
Further, described ceramic plug and stainless steel pipe box are through 3 ~ 8 layers of high-temperature plastic sealed engagement.
The beneficial effects of the utility model main manifestations is:
1. owing to adopting high-temperature plastic and ceramic plug to seal heat-generating pipe, avoided outside liquid immersion;
2. ceramic plug socket has well been avoided use electric wire, prevent that electric wire lost efficacy because being oxidized and wearing and tearing in high-temperature mobile work, cause that short circuit accident occurs, can make under heat-generating pipe hot soak condition, heat-generating pipe body and electric lead can not break down because of high temperature or wearing and tearing, for heat-generating pipe entirety is worked and has been cleared away obstacle under hot conditions. heat-generating pipe entirety can be worked in environment more than 800 ℃, longer service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of heat-generating pipe in the utility model one embodiment.
Wherein 1 is magnesia powder, the 2nd, and magnesium oxide rod, the 3rd, heat-generating pipe, the 4th, electric lead, the 5th, heating wire, the 6th, ceramic plug, the 7th, ceramic socket, the 8th, the pin public affairs of colding pressing, the 9th, the pin mother that colds pressing, the 10th, high-temperature insulation composite plate, the 11st, stainless steel pipe box.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
A kind of Noval exothermic tube, comprise body and be placed in the heating wire 5 in body, in described body, be also provided with magnesium oxide rod 2, described heating wire 5 is wound on magnesium oxide rod 2, and be electrically connected with ceramic plug 6 via the electric lead 4 passing in magnesium oxide rod 2, described ceramic plug 6 is tightly connected with described body, and, between described body and heating wire 5, be also filled with magnesia powder 1; It also comprises that adapter sleeve is located at the stainless steel pipe box 11 on body, described ceramic plug 6 and stainless steel pipe box 11 sealed engagement, described ceramic plug 6 is provided with the pin public affairs 8 of colding pressing, the described pin female 9 of colding pressing matches with the pin of colding pressing male 8 on ceramic socket 7, described ceramic plug 6 is connected with body one end, and the described body other end is filled with solid insulation, on described ceramic socket 7, be enclosed with high-temperature insulation composite plate 10, described electric lead 4 adopts pure nickel line, and described ceramic plug 6 and stainless steel pipe box 11 are through 3 ~ 8 layers of high-temperature plastic sealed engagement.
Ceramic plug 6 is connected with the ceramic socket 7 of insulation, does not need directly to connect with electric wire, has avoided electric wire problem of aging, has reduced the time that need frequently disconnect electric wire and installation; And electric lead 4 is connected to form loop with heating wire 5, make electric lead 4 avoid hot operation district completely.
Owing to adopting high-temperature plastic and ceramic plug 6 to seal heat-generating pipe 3, avoid outside liquid immersion, also play good insulation effect.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalent transformations doing according to the utility model Spirit Essence or modification, all should be encompassed in protection range of the present utility model.
