Description

A kind of nitriding furnace combustion system
Technical field
The utility model is related to nitriding furnace.
Background technology
Nitriding furnace is the equipment that Nitrizing Treatment is carried out to workpiece, and the principle of nitriding is:Workpiece is put into nitriding furnace, is first arranged Go out the air of nitriding furnace, ammonia is then passed through into nitriding furnace, heat, then cool down.
Nitriding furnace, it is necessary to be heated to nitriding furnace, has very when carrying out nitriding to workpiece to the mode for nitrogenizing stove heat Right, such as electrical heating is heated by burning fuel.In general, after the bell of nitriding furnace is opened, then it need not be added Heat, current equipment needs artificial stopping heating, then when bell is opened, if forgetting to stop heating, on the one hand waste energy Source is on the other hand dangerous.
The content of the invention
The purpose of this utility model is to provide a kind of nitriding furnace combustion system.Using structure of the present utility model, work as bell During opening, it is cut off by the combustion gas of combustion furnace, stops heating, saved the energy, on the other hand also improved security performance.
To reach above-mentioned purpose, a kind of nitriding furnace combustion system, including elevating mechanism, upper bracket, fuel cartridge and combustion furnace; Elevating lever and be connected to elevating lever that described elevating mechanism is located on guide sleeve including the guide sleeve on furnace shell, slip On support, on elevating lever be provided with cylinder, bell is connected with support;Described upper bracket includes column and cross bar, stands Post is fixed on support, and cross bar is fixed on the upper end of vertical rod;Fuel cartridge has been hung on cross bar;Air inlet pipe is provided with combustion furnace, Air inlet pipe is provided with valve, and cam is provided with valve, connecting rod is fixed with cam, provided with laterally setting on elevating lever Chute, one end of connecting rod is extend into chute;Flexible pipe is provided between air inlet pipe and fuel cartridge.
Said structure, drives elevating lever to move upwards, elevating lever is moved along guide sleeve by cylinder, and elevating lever drives branch Frame is moved upwards, and support drives bell to open, while support drives upper bracket to move upwards.Elevating lever is in upward motion process In, in the presence of chute, connecting rod band moving cam rotates, and valve is closed, so, the combustion gas in fuel cartridge would not enter Into combustion furnace, combustion gas disconnects, then the burning in combustion furnace stops, and realizes stopping heating, has saved the energy, also improved peace Full performance.Due to being provided with cross bar, therefore, burn pot is conveniently hung.If desired for close bell, by cylinder drive elevating lever to Lower motion, elevating lever drives support to move downward, so as to drive bell to close, elevating lever is during moving downward, in chute In the presence of, reversely rotated by connecting rod band moving cam, open valve, combustion gas can be supplied to combustion furnace.
Further, it is located in vertical rod below cross bar and is fixed with support rod, is fixed with and adds between support rod and support Strong bar.Described support rod be located at fuel cartridge lower section, can play a part of support fuel cartridge, allow fuel cartridge placement more Safety.
Further, latch is provided with cross bar, can prevent fuel cartridge from departing from cross bar, improve security performance.

Embodiment
The utility model is further elaborated with reference to the accompanying drawings and detailed description.
Referring to Fig. 1 and Fig. 2, nitriding furnace combustion system includes furnace shell 1, bell 3, combustion furnace 4, elevating mechanism 6, upper bracket 7 With fuel cartridge 73.
Bell 3 is covered on furnace shell 1.
Elevating mechanism 6 is provided between furnace shell 1 and bell 3.Described elevating mechanism 6 include guide sleeve 61, elevating lever 62, Support 63 and cylinder 64.
Guide sleeve 61 is arranged on by connecting seat 60 on the lateral wall of furnace shell 1, and the upper end of connecting seat 60 has snap fit 600, Snap fit holding can play spacing effect on the upper surface of furnace shell 1.What elevating lever 62 was slided passes through guide sleeve 61, support 63 The upper end of elevating lever 62 is connected to, bell 3 is connected on support 63, and cylinder is fixed on connecting seat, the piston rod of cylinder 64 connects It is connected on elevating lever 62.
Upper bracket 7 is fixed with support 63, upper bracket 7 includes column 71 and cross bar 72, and column 71 is fixed on support 63 On, cross bar 72 is fixed on the upper end of vertical rod 71 and cross bar extends from vertical rod to two ends, and fuel cartridge 73 is hung with cross bar 72, works as horizontal stroke After bar extends to two ends, the fuel cartridge 73 hung is to vertical rod stress balance.By setting cross bar, it is being easy to place fuel cartridge 73, Make full use of space.In order to prevent fuel cartridge from slipping away cross bar, latch is provided with positioned at the outside of burn pot on cross bar(It is not shown).
It is located in vertical rod 71 below cross bar and is fixed with support rod 74, reinforcement is fixed between support rod 74 and support 63 Bar 75.Described support rod 74 is located at the lower section of fuel cartridge, can play a part of supporting fuel cartridge 73, allows the placement of fuel cartridge 73 It is more safe.
As shown in Figures 2 to 5, air inlet pipe 41 is provided with combustion furnace 4, air inlet pipe 41 is provided with valve 42, in valve 42 Cam 43 is provided with, connecting rod 44 is fixed with cam 43, provided with the chute 621 laterally set on elevating lever 62, connection One end of bar 44 is extend into chute 621;Flexible pipe 45 is provided between air inlet pipe 41 and fuel cartridge 73.
Said structure, drives elevating lever to move upwards, elevating lever is moved along guide sleeve by cylinder, and elevating lever drives branch Frame is moved upwards, and support drives bell to open, while support drives upper bracket to move upwards.Elevating lever is in upward motion process In, in the presence of chute, connecting rod band moving cam rotates, and valve is closed, so, the combustion gas in fuel cartridge would not enter Into combustion furnace, combustion gas disconnects, then the burning in combustion furnace stops, and realizes stopping heating, has saved the energy, also improved peace Full performance.Due to being provided with cross bar, therefore, burn pot is conveniently hung.If desired for close bell, by cylinder drive elevating lever to Lower motion, elevating lever drives support to move downward, so as to drive bell to close, elevating lever is during moving downward, in chute In the presence of, reversely rotated by connecting rod band moving cam, open valve, combustion gas can be supplied to combustion furnace.
