Description
Technical field
The utility model relates to radiant tube, particularly relates to a kind of heating radiation pipe of improvement.
Background technology
Radiant tube is a kind of conventional heater, usually adopts electric energy or high-quality gas (steam) to realize heating in use, and it is extensive that it applies very in the industry such as metallurgy, medicine, food.Existing radiant tube, there is heat utilization rate low, radiant tube uses the defects such as rear easy distortion for a long time, and existing radiant tube is in use due to the length of radiant tube and the relation of caliber in addition, there will be radiant tube inside and there is temperature difference, back segment is often low than the temperature of leading portion tens degree, have a strong impact on temperature homogeneity and the heat transfer efficiency of burner hearth inside, can not user demand be met, and the heater in radiant tube is due to long use, easily aging, cause needing to change.Therefore, a kind of new technical scheme should be provided to solve the problem.
Summary of the invention
The purpose of this utility model is: for above-mentioned deficiency, provides a kind of heating radiation pipe of improvement.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of heating radiation pipe of improvement, comprise radiant tube body, the end of radiant tube body is provided with adpting flange, the part that radiant tube body is positioned at stove is bending, radiant tube body is provided with multiple elbow, be provided with by resistance electrothermal alloy bar in elbow, electrode lead-out rod is provided with in the rear end stroke of radiant tube body, soaking zone is provided with between electrode lead-out rod and resistance electrothermal alloy bar, the potsherd that docile elbow is arranged is provided with outside elbow, be wound with resistance wire outside potsherd, the outer wall of radiant tube body is coated with one deck far infrared radiation skin.
The outside of each elbow is equipped with base for supporting.
The thickness of far infrared radiation coating is 10-20 μm.
Due to the application of technique scheme, the utility model compared with prior art tool has the following advantages:
1, be provided with soaking zone in radiant tube body, the front and back temperature of radiant tube body is consistent.
2, the outer wall of radiant tube body is coated with far infrared radiation coating, can make lengthen the useful life of radiant tube body, and operating efficiency raises.
3, adopt this external resistance wire of radiant tube intrinsic resistance electrothermal alloy bar and radiant tube, adopt the mode of double-layer heating, when can extend heating and useful life.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment one external structure schematic diagram.
In above accompanying drawing: 1, radiant tube body, 2, adpting flange, 3, elbow, 4, resistance electrothermal alloy bar, 5, electrode lead-out rod, 6, soaking zone, 7, potsherd, 8, resistance wire, 9, far infrared radiation is outer, 10, base for supporting.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As shown in Figure 1, the heating radiation pipe of a kind of improvement of the utility model, comprise radiant tube body 1, the end of radiant tube body 1 is provided with adpting flange 2, the part that radiant tube body 1 is positioned at stove is bending, radiant tube body 1 is provided with multiple elbow 3, be provided with in elbow 3 by resistance electrothermal alloy bar 4, electrode lead-out rod 5 is provided with in the rear end stroke of radiant tube body 1, soaking zone 6 is provided with between electrode lead-out rod 5 and resistance electrothermal alloy 4 rod, the potsherd 7 that docile elbow is arranged is provided with outside elbow 3, resistance wire 8 is wound with outside potsherd 7, the outer wall of radiant tube body 1 is coated with one deck far infrared radiation skin 9.
The outside of each elbow 3 is equipped with base for supporting 10.
The thickness of far infrared radiation coating 9 is 10-20 μm.
Be provided with soaking zone in radiant tube body 1, the front and back temperature of radiant tube body 1 is consistent.
