Specific embodiment
Describe particular content of the present utility model in conjunction with accompanying drawing in detail.Well formula carbo-nitriding stove, including body of heater 1 and bell 2,
The outer wall bottom of described body of heater 1 is provided with bearing 3, and body of heater 1 outer wall directly over bearing 3 is provided with multiple axle sleeves 4, solid on bearing 3
Surely there is screw lift structure, the top of this screw lift structure is connected with the bottom of lifting shaft 6 by pressure bearing 5, lifting shaft 6
Run through multiple axle sleeves 4 and be slidably matched with axle sleeve 4, the diameter parallel of the axis of lifting shaft 6 and body of heater 1, the top of described lifting shaft 6
End is vertically connected with rocking lever 7, and the other end of rocking lever 7 is fixedly connected with electric machine casing 8, and this electric machine casing 8 is propped up by motor
Seat 9 is fixedly connected with bell 2, and the output shaft of motor is fixedly connected through bell 2 with fan blade 10, and the end of rocking lever 7 is provided with handss
Handle 11.
Described body of heater 1 bottom is fixed on refractory brick 12, and the inwall of this body of heater 1 has been bolted insulation fibre
Cotton 13, the inner side of insulation fibre cotton 13 is provided with the resistance wire 14 being fixed on body of heater 1 inwall.
Described screw lift structure is made up of motor 15, reductor and turbine screw lift 16, wherein drives
The outfan of motor 15 is connected with the horizontal input shaft of turbine screw lift 16 by reductor, turbine screw lift 16
