Description
Technical field
The utility model is related to a kind of electric heater, and in particular to one kind is used for electric radiant tube electric heater.
Background technology
Electric radiant tube heater is important component on ammonia combustion atmosphere stove, it is existing including radiant tube, heater, flange, plus
Hot device fixed cover and end cap, flange, end cap are respectively fixedly connected with the two ends of radiant tube.Existing electric radiant tube heater is being used
Column defects in the presence of Shi Faxian：Air-tight state is in radiant tube, when sealing goes wrong, it is possible to negative pressure state, stove occur
The gas of interior carbon potential high is invaded in radiant tube, and electric heater may be by carburizing and deposition carbon black；In addition, being in sealed shape in radiant tube
State, electric heater heat cannot be distributed, and temperature is higher, and radiant tube internal-external temperature difference is big, aggravate electric heater overheat tendency, and electric heater is used
Short life.In Chinese patent 201420210367.1 " being provided with the electric radiant tube of aeration structure ", be provided with lid with pipe shaft
Upper through hole, lower through-hole that chamber communicates, when this electric radiant tube is used, upper through hole naturally drains hot-air, and lower through-hole is sucked naturally
Cool air, inner cavity of tube body air can flow, and improve the thermal efficiency and service life of electric radiant tube.But due to upper through hole, lower logical
Hole is at one end, it is impossible to form the air-flow of covering electric heater, therefore, when using, electric heater be able to cannot still be distributed because of heat, be produced
Heat tendency, electric heater service life is short.
The content of the invention
The utility model is in view of the shortcomings of the prior art, there is provided one kind can protect electric heater not by carburizing and deposition carbon black,
And radiating is abundant, overheat is not produced to be inclined to, significantly the energy-saving electrical radiant tube heater of extension electric heater service life.
The utility model is achieved through the following technical solutions technical goal.
Energy-saving electrical radiant tube heater, including straight-tube shape radiant tube, heater, flange, heater fixed cover and end cap；
The flange, end cap are respectively fixedly connected with the two ends of radiant tube；The heating part of the heater is arranged in radiant tube, its
Hole of the end on flange, and flange outer face is fixedly connected on by heater fixed cover；It is theed improvement is that：It is described
End cap is provided with hole；Be provided with gap between the hole run through for end part of radiant tube on the flange and the radiant tube for running through, with plus
Blow vent on hot device fixed cover is communicated.
In said structure, the radiant tube heater end be provided with the inwall between flange at least together with annular every
Fault trough.
In said structure, high temperature resistant nonmetallic materials are provided with the partition grooves.
In said structure, the high temperature resistant nonmetallic materials are refractory ceramics mud.
The utility model compared with prior art, has the positive effect that：
1st, gap is provided between the hole run through for end part of radiant tube on flange and the radiant tube for running through, is fixed with heater
The blow vent for putting is communicated, and end cap is provided with hole, so, forms the gas channel from flange to end cap, there is following several respects
Effect：On the one hand, when using, because endlessly pure ammonia combustion atmosphere is full of radiant tube, and certain malleation is maintained,
Prevent the gas of carbon potential high in stove from invading in radiant tube, protection electric heater will not be by carburizing and deposition carbon black.Even radiant tube
When crackle occurs in body, due to being in barotropic state in radiant tube pipe, still can play a part of to protect electric heater；On the other hand,
When cold protective atmosphere flows through electric heater, a part of heat is taken away to stove, reduce the temperature of electric heater, reduce radiant tube
The inside and outside temperature difference, thus electric heater overheat tendency is alleviated, significantly extend electric heater service life.
2nd, radiant tube heater end be provided with the inwall between flange at least together with annular partition grooves, so,
When using, partition grooves play blocking effect, substantially reduce the effect of heat transfer, significantly improve the efficiency of heating surface, also significantly subtract
Lack energy loss, save the energy；Certainly, set partition grooves are more, and the blocking effect for rising is more obvious.
3rd, high temperature resistant nonmetallic materials are provided with partition grooves, further cut-off effect is played, heat are further reduced and is passed
Pass.
4th, radiant tube is seamless high-temperature alloy pipe, and electric radiant tube can be made to have service life more long.
Brief description of the drawings
