As shown in Fig. 2, the heat in tempering furnace 1 can pass through gas vent 231 due to after completing oil flue waste gas burning
It scatters and disappears, causes the heat loss in tempering furnace 1 too fast, reduce the effect of tempering.Therefore be connected with can for the sliding of 23 upper end of combustion furnace
By the closed cover board 26 of gas vent 231,23 upper end of combustion furnace is opened up there are two slippage slot 232, and two slippage slots 232 are located at
The two sides of gas vent 231.26 lower end of cover board is welded with two sliding blocks 261 cooperated with slippage slot 232, and sliding block 261 can be placed in cunning
Move sliding in slot 232.Gas vent 231 is closed using cover board 26 after oil flue waste gas burning is completed, at this time in tempering furnace 1
Air can not flow to the external world by gas vent 231, to reduce the speed of heat loss in tempering furnace 1, make the effect of tempering
It keeps stablizing.
As shown in Fig. 2, needing artificial movement when due to movable cover plate 26, the temperature of cover board 26 is higher to easily make one at this time
It is injured.Therefore 23 upper end of combustion furnace is provided with the mobile cylinder 27 of driving cover board 26, and the cylinder body of cylinder 27 uses bolt and burning
The connection of 23 upper end of furnace, the side wall use of piston rod and cover board 26 is bolted, and the length side of the axis of cylinder 27 and sliding slot
To parallel.Using cylinder 27 push cover board 26, thus make manually will not with cover board 26 generate contact, make operator will not because with
Cover board 26 contact and it is injured.
As shown in Figure 1, due to needing to be piled up in exhaust gas in combustion furnace 23 during oil flue waste gas burns, it
Oil flue waste gas is lighted again afterwards, gas vent 231 is in the open state at this time, and exhaust gas can be got into the air by gas vent 231.
Therefore 23 upper end of combustion furnace is provided with the air curtain mechanism 4 for preventing oil flue waste gas lost, air curtain mechanism 4 include air compressor 41,
Blast pipe 43 for manufacturing the spray head 42 of air curtain and connecting spray head 42 with air compressor 41.42 use of spray head is bolted
In the side inner wall of gas vent 231, one side wall of the air outlet towards gas vent 231 far from spray head 42.One end of blast pipe 43
Make the air inlet for being bolted to spray head 42, the air outlet use of the other end and air compressor 41 is bolted.It utilizes
Air compressor 41 forms one layer of air curtain by spray head 42 at gas vent 231, cannot be introduced into the oil smoke mixed in exhaust gas outer
Boundary, to reduce the pollution of air.
As shown in Figure 1, due to by cover board 26 be closed after air compressor 41 stop working, at this time in combustion furnace 23
Hot-air can be entered in air compressor 41 by air inlet pipe, to cause scattering and disappearing for heat in tempering furnace 1.Therefore blast pipe 43
It is connected with check valve 44, check valve 44 is connected towards 42 direction of spray head.Make hot-air that can not pass through blast pipe using check valve 44
43, to reduce scattering and disappearing for heat in tempering furnace 1.
Working principle:
When work, workpiece is placed in tempering furnace 1, tempering furnace 1 heats workpiece later, and starting cylinder 27 at this time makes
Cover board 26 is mobile, so that cover board 26 be made to open gas vent 231.Air compressor 41 and exhaust fan 22 are started simultaneously, utilized
Exhaust gas containing oil smoke is pumped into combustion furnace 23 by exhaust fan 22, and cannot be introduced into oil flue waste gas outside using air curtain mechanism 4
In boundary's air, so that oil flue waste gas is burnt using igniter 24 later, the oil smoke in exhaust gas is handled.It burns in oil flue waste gas
During, heat adds the air in insulation cover 31 by the first heat-exchange tube 32 and the second heat-exchange tube 33 using medium
Heat, so that the air entered in tempering furnace 1 be made to reduce the temperature in tempering furnace 1.After oil flue waste gas is burnt,
Air compressor 41 is set to stop working, starting cylinder 27 upholds its piston rod, to push cover board 26 by 231 envelope of gas vent
It closes.
Specific embodiment is only the explanation to the utility model, is not limitations of the present invention, this field
Technical staff can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but only
It will be in the scope of the claims of the utility model all by the protection of Patent Law.
