Black case, 8- thermocouple a, 9- thermocouple b, 10- body of heater.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1～2, a kind of vacuum drying oven heating system, including body of heater 10, inside described body of heater 10, it is provided with graphite boxes 7,
Graphite boxes 7 are provided with heating tube a1 above left side, left side is provided with heating tube d4, be provided with heating tube e5 below left side；On the right side of graphite boxes 7
Top is provided with heating tube b2, right side is provided with heating tube c3, lower right-hand side is provided with heating tube f6；Heating tube a1, heating tube b2, heating
Pipe c3, heating tube d4, heating tube e5 and heating tube f6 are evenly distributed on outside graphite boxes 7, and heating element heater is uniformly distributed, and are formed steady
Fixed temperature space；Wherein heating tube a1, heating tube d4 and heating tube e5 are formed a heating module and are connected with thermocouple a8,
Heating tube b2, heating tube c3 and heating tube f6 are formed another heating module and are connected with thermocouple b9, and each heating module is used
One transformator and a pid control the temperature and time heating, transformator and pid to be connected with touch screen；Heating tube is uniformly divided
Cloth, around graphite boxes 7, is provided that uniform heat affected zone.
Further, it is provided with heat-insulation layer, cramped construction inside body of heater 10 described in the utility model, reduce keeping warmth space, tool
