Be provided with quartz layer in described body, the cylindrical tube of up/down perforation centered by described quartz layer, and close adhesion is on the inwall of body.
Described quartz layer be the quartz sand of particle adopt the mode of spraying to be arranged at inboard wall of tube body tooth bar between gap in.
Described heater comprises core body and resistance wire, and the outer surface of described core body is provided with helical groove, and described resistance wire is wound around and is arranged on core body and is filled by helical groove full.
Described resistance wire is provided with temperature sensor.
Described body with between connector for being threaded.
The peripheral shape of described body is hexagon.
The utility model adopts and on inboard wall of tube body, arranges tooth bar and arrange quartz sand layer on inboard wall of tube body, and core body arranges the technical scheme of helical groove, and the cooling and insulating effect overcoming existing electrothermal blowing pipe body is poor, the defect that use cost is high.
The beneficial effects of the utility model:
1) body and connector adopt dismountable mode to link together, when the resistance wire in body distortion or body needs can change easily when changing, adopt and be coated with magnesium oxide coating on resistance wire, be convenient to resistance wire close around, to insulate between resistance wire and resistance wire, resistance wire short circuit is avoided to conduct electricity and burn out heater.
2) employing arranges the multiple tooth bars side by side extended vertically on the inwall of body, gap between adjacent two tooth bars forms air communication channel together, substantially increase the effective area of dissipation of body, thus improve the radiating effect of body, avoid when the quartz layer in body come off affect effect of heat insulation time, cause the too high safety problem caused of the temperature of tube wall.
3) employing arranges quartz layer on inboard wall of tube body, avoids causing body temperature too high because heater heating, plays the effect of insulated heat.
4) adopt the position being positioned at tooth bar on inboard wall of tube body that quartz sand layer is set, existence due to tooth bar makes the contact area of inboard wall of tube body and quartz sand layer strengthen, with the gap between hour rack and tooth bar can make quartz sand layer more firm be fitted on the inwall of body, decrease the use amount of quartz, reach and also can reach good insulated heat effect with less quartz, reduce purchase cost, economize on the use of funds.
5) employing arranges helical groove on core body, and resistance wire is in helical groove, thus institute can be increased on core body make heating effect better around resistance wire quantity, time simultaneously under installing heat-generating pipe position and being in an unsure state, resistance wire can not arbitrarily movement, because ceramic core body has well heat transfer and radiating effect, can fully be come out by heat energy, effective and reasonable make use of electric energy, reduces energy consumption, and not fragile, extend the useful life of heat-generating pipe.
6) adopt set temperature transducer on resistance wire, with the heating temp of controlling resistance silk, avoid resistance wire heating temp too high.
7) body is set to, in polygonal external shape, strengthen the intensity of body by employing.
