Preferably, the fixed part of said heater is the double-deck screw circulus that is crisscross arranged, and the heater block of heater is resistive band or resistance wire, is wavy winding and is arranged on the double-deck screw circulus.
Preferably, the fixed part of said heater is an insulating materials.
Preferably, be provided with packing ring between the heater block of said heater and the folding module.
Preferably, said thermal insulating layer is made up of the high aluminum fiber blanket, and said folding module is the folding module of high alumina temperature fiber.
Preferably, said heating furnace also comprises block, is arranged at each heater top, and block is made up of the heat-resistant light insulating materials of hollow.
Preferably, said heating furnace also comprises the reactor lead, is fixedly set in body of heater metal shell inwall fire door place, and reactor lead length is greater than the thickness of thermal insulating layer thickness and heater, and lead is made up of heat-resistance stainless steel.
The beneficial effect of the utility model:
1, heater top is provided with that block can effectively solve and damages the problem of heater because the oxidized metal cortex drops on heater.
2, heater can be according to the selection adjustment quantity of the size of body of heater and power, and cooling is faster when heating up faster, blowing out during work.
Advantages such as it is lighter that the refractory brick body of heater that 3, the structure of the utility model body of heater is traditional relatively has body of heater weight, and whole service life is longer, and sealing property is better, and the specific yield energy consumption is lower.
