Abstract
The utility model provides an anti-explosion tracing ribbon, which relates to a heating device for combustible and explosive medium metal tanks, the heating method is the contact conduction with the highest efficiency of heat transfer, the anti-explosion tracing ribbon is internally provided with a non-metal electrically-heated line, compared with a metal resistance thread, the non-metal electrically-heated line has the advantages of a surface ten times larger than that of the metal resistance thread with the same resistance value, without turning red, heating or visible light in working condition, without oxidization, long service life, heating efficiency of 96.5 percent and self temperature-limiting, the non-metal electrically-heated line is covered with a stainless steel net and a rubber layer, being soft, flame-retardant, anti-water, and oil-resistant, the inside of the rubber layer is filled with metal oxide with high heat transfer efficiency, while the outside of the rubber layer is filled with the material with good heat preservation.
Description
Technical field
The utility model relates to the explosion-proof electric apparatus field.
Background technology
Accompany hot device with resistance-type in the environment that has inflammable and explosive medium to exist, by GB GB3836.1.3-2000 design.The red heat during work of explosion-proof companion's thermic devices complex structure on the market, metallic resistance silk, no metal armor, coefficient of safety are low, do not reach GB GB3836.1.3-2000 requirement.This explosion-proof heating tape is filled up this blank.
Summary of the invention
(1), explosion-proof heating tape uses carbon fiber heating line to do pyrotoxin;
(2), the carbon fiber heating line insulating layer crust of explosion-proof heating tape braiding stainless steel fiber tube protection armor;
(3), use the bimetal leaf overheat protector to realize limit temperature automatically in the adhesive tape of explosion-proof heating tape;
(4), the rubber layer of explosion-proof heating tape divides the interior outside, the inboard good metal oxide of heat conduction, the outside fill insulant material of filling.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model circuit theory diagrams.
Among the figure 1, heat-proof combustion-resistant rubber; 2, bimetal leaf overheat protector; 3, three core power lines; 4, stainless steel fiber tube protection armor; 5, heat-resistant insulating layer; 6, carbon fiber heating line.
Embodiment
Explosion-proof heating tape inner disc is put carbon fiber heating line, this line and metallic resistance silk relatively, surplus resistance surface area big 10 times.The no red heat visible light of low temperature heating, not oxidation, long service life, heating efficiency 96.5%.Explosion-proof heating tape mode of heating is the highest contact conduction of heat transfer efficiency.The heating wire heat-resistant insulating layer twines behind the stainless steel wire and constant temperature bimetal leaf temperature overheating temperature detect switch (TDS), is pressed together in fire-retardant, waterproof, oil resistant, the heat-resisting rubber, and the inboard good metal oxide of heat conduction of filling of this rubber, the material of good heat preservation performance is filled in the outside.
The heating tape area is changeable, and power density is constant.Just determine power according to tank body size, temperature.
Example: be used for the explosion-proof heating tape of Φ 400 * 1000mm tank body, tank wall temperature 35.(see figure 2)
Supply voltage: 220V frequency 50Hz
Power 400W electric current 2A
Power density: 0.17W/CM2
Carbon fiber heating line is done pyrotoxin, heat-resisting 200 ℃ of silicone rubber insulation layer, heat-resisting 150 of insulating layer of Teflon, heat-resisting 105 of PVC layer.The polyvinyl chloride insulation carbon fiber heating line: model 30K/ resistance 17 Ω/M, two parallel connections of 14.35M, overheated insurance that automatically resets of every heating line series connection, temperature reaches 60 ℃ of automatic disconnections in 60 ℃ of the design temperatures, explosion-proof heating tape, drops to 35 ℃ and automatically resets.Be injection-moulded in the 1200mm*200mm offset plate.
Resistance: 17 Ω/m * 14.35m=244 Ω
Power: P=2 * 220 * 220/244=396.72W
Electric current: I=220/122=1.8A
The carbon fiber heating line insulating layer crust braiding stainless steel fiber tube protection armor of explosion-proof heating tape; Stainless steel wire 0.12mm silk footpath, area coverage 80%
Practical test:
1, ambient temperature is 5 ℃, power supply 220V/50Hz, and companion's thermal source is at tank wall, apart from end 200MM.Switched on actual measurement 48 hours: electric current 1.8A, companion's thermal source covers 45 ℃ of central temperatures, 25 ℃ of companion 100MM place, thermal source top temperature, tank body middle part 10 ℃ of temperature (mean temperature), well below 60 ℃, can long-term safety work.
2, ambient temperature 25 degree, other conditions are the same, actual measurement: electric current 0.9A, companion's thermal source cover central temperature 45 degree, 100MM place temperature 35 degree, tank body middle part temperature 28 degree.
Reach designing requirement.
