There are temperature sensor and solenoid valve, all temperature sensors and solenoid valve are connect with controller.
The inner wall of the burner hearth is provided with insulating liner, and the insulating liner includes insulating layer and flame retardant coating, described
Flame retardant coating is located at the most inboard of the burner hearth and directly contacts with heat source；The insulating layer is aluminium oxide insulation board, the fire resisting
Layer is mullite flame-proof cellucotton.
The beneficial effects of the utility model are:
1, the utility model has former and later two fire doors, and heat dissipation is faster；Front and back fire door respectively has a peep hole, can slap in real time
In-furnace temperature is controlled, monitors reaction in furnace situation, it can be seen that whether have drainage in furnace；Oven door opening is closed easily,
Hand-held impact gun can be arrived quickly and be opened or closed.
2, the utility model useful load is big, and Double-tray takes on furnace；Water circulation system is realized to stove to (front and back in all directions
Fire door and furnace shell) protection；Heating rate and time can be controlled at any time to setting in heating；The furnace that hole is seen according to the observation
Next furnace temperature curve can be arranged and time for reacting in interior situation in real time；It with real time inspection fault alarm reason and can go through in the past
History operation note.
3, it is inflated when the utility model operation stove more convenient；Two fire doors can clean simultaneously, more convenient.
Suitable calandria is added in the bottom of burner hearth, is increased to temperature of lower as top, reduction even is eliminated the temperature difference, improves
Product quality, also, calandria uses temperature-adjustable structure, is convenient for regulating and controlling temperature.
4, the utility model is designed reasonably, structure it is simple, it is easy to use and be convenient for thermometric, implementation easy to spread, have it is good
Good economic benefit.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the novel nitriding furnace of double-door type；
Fig. 2 is the side view internal structure chart of the novel nitriding furnace of double-door type in Fig. 1.
Specific embodiment:
Embodiment: referring to Fig. 1-Fig. 2, in figure, 1- furnace shell, 2- fire door, 3- burner hearth, 4- charging tray, 5- insulating liner.
The novel nitriding furnace of double-door type includes furnace shell 1, burner hearth 3 and fire door 2, and the inner cavity two sides of burner hearth 3 are respectively arranged with side
Heating tube, side heating tube are connect by electrode with external power supply, and the inner cavity lower part of burner hearth 3 is provided with pillar and supporting plate, on supporting plate
