Embodiment
The present invention is for defect present in prior art, there is provided a kind of combustor baking oven, it can solve the problem that existing combustion
Burning formula baking oven easily triggers blast, security low and the problem of energy consumption is big, and concrete thought is as follows：By setting phase in baking oven
The heating passage and hot-air circulation canal mutually completely cut off, the outer air of heating passage burning baking oven distribute heat, and hot-air circulation is logical
Road is circulated the hot-air in baking oven using the heat for heating passage, simple in construction, can be realized in baking oven and be followed in air
Ring, the utilization rate of energy is improved, while air in baking oven and flame isolation are opened, improve security performance.
Embodiment one：
As shown in figure 1, the invention provides a kind of combustor baking oven, including casing 1 and it is arranged at the outer wall of casing 1
Combustor 2, the inside of casing 1 have receiving space 11, and the combustor baking oven also includes：Burning heater 3, is arranged at
In the casing 1, the burning heater 3 is internally formed heating passage S1, the heating passage S1 and the receiving space
11 isolations, and the heating passage S1 passes through the side wall of the casing 1 and the ft connection of the casing 1；Hot-air circulation dress
4 are put, is arranged in the casing 1 and is sheathed on outside the burning heater 3 of part, inside the hot air circulation unit 4
It is logical formed with hot-air the circulation canal S2, the hot-air circulation canal S2 connected with the receiving space 11 and the heating
Road S1 completely cuts off.Heat is distributed by heating air outside passage S1 burning baking ovens, hot-air circulation canal S2 is utilized and heated passage
Heat is circulated the hot-air in baking oven, can realize internal air circulation in baking oven, improves the utilization rate of energy, simultaneously will
Air is opened with flame isolation in baking oven, improves security performance.
Specifically, burning heater 3 includes：Combustion chamber 31, its combustor 2 with being arranged at the outside wall surface of casing 1
So that the combustor 2 burns, caused flame is in the combustion chamber 31 for connection；At least one heat conducting pipe 32, one end with
The combustion chamber 31 connects, for heat transfer caused by the combustor 2 is burnt to the hot-air circulation canal S2.
In the present invention, three heat conducting pipes 32 are set side by side with, each heat conducting pipe 32 is that one end connects with combustion chamber 31, and is led
Fin can also be arranged on heat pipe 32 further to increase heat-transfer surface.
In one embodiment of this invention, the heat conducting pipe 32 all/(i.e. spring-like) disk is located at institute in the shape of a spiral for part
State between combustion chamber 31 and the blast pipe 43.The receiving that spiral helicine setting adds heat conducting pipe 32 and heated outside passage S1 is empty
Between in 11 air contact area, also play the effect of increase heat conduction.
As shown in Fig. 2 in another embodiment of the invention, the acceptable whole of heat conducting pipe 32/partly set in straight tube, directly
Although tube shape sets the contact area for reducing air in heat conducting pipe 32 and receiving space 11, airflow is easy for, heat
Amount is transmitted quicker.
Specifically, burning heater 3 also includes：Blast pipe 33, one end is with the heat conducting pipe 32 away from the combustion chamber
31 one end connection, the other end connects outside through the side wall of the casing 1 with casing 1, after the combustor 2 is burnt
Air is drained into outside the casing 1；The combustion chamber 31, heat conducting pipe 32 and the connection of the blast pipe 33 form the heating passage
S1。
In the present embodiment, hot air circulation unit 4 includes：Induced duct 41, it is outer and one to be sheathed on the heat conducting pipe 32
End is connected to the lateral wall of the combustion chamber 31, is connected with the receiving space 11；Blower fan 42, with the induced duct 41 away from institute
State one end connection of combustion chamber 31；Airduct row 43, connects with the blower fan 42 and the receiving space 11；The induced duct
41st, blower fan 42 and the connection of airduct row 43 form the hot-air circulation canal S2.In order to reduce hot-air cyclic process
In heat scatter and disappear, combustion chamber 31 and the blast pipe 33 are that heat-barrier material makes.In the present embodiment, the airduct
Row 43 has two, and two airduct rows 43 are oppositely arranged, its respective central axis X copline, meanwhile, two airduct rows 43
Cross-sectional area be gradually reduced away from the direction of blower fan 42, it is possible thereby to improve the air current flow speed at osculum end, improve
Cycle efficieny；Generally, as shown in figure 3, the air in receiving space 11 enters two airducts under the driving of blower fan 42
Row 43, and discharged from the free end 431 of two airduct rows 43 respectively, on this basis, described two airduct rows 43 are relative
At least one opening 433 can be also provided with side 432, thus, air can also be gone out by the counter current flow of opening 433, realize air-flow
Liquidate, thus beneficial to Diffusion of gas stream, further strengthen the heat exchange that air-flow passes through heat conducting pipe 32.
In order that the air circulation circulation in receiving space 11 and hot-air circulation canal S2, induced duct 41 is close to the combustion
One end side wall for burning room 31 offers at least one air inlet 411, and the air inlet 411 is used to make in the receiving space 11
Air enters in the induced duct 41 under the driving of the blower fan 42.
Because combustion chamber 31 and receiving space 11 completely cut off, to admit air into combustion chamber 31, casing 1 offers to be entered for air
Enter the air inlet 12 of the combustion chamber 31, and the combustion chamber 31 is connected by the air inlet 12 with the combustor 2.
As shown in Fig. 2 Fig. 2 is combustor baking oven interior air-flow provided by the invention circulation schematic diagram, combustion heating passage gas
Stream is as follows：Gas enters combustion chamber 31 from air inlet 12, and after the burning of combustor 2, hot-air flows into heat conducting pipe 32, heat conducting pipe 32
To induced duct 41, the air after heat transfer passes through blast pipe 33 and discharges casing 1 interior hot-air heat transfer；Hot-air circulates
Circulation path is as follows：In the presence of blower fan 42, the air in receiving space 11 enters induced duct 41, air inducing from air inlet 411
Air in pipe 41 flow to blower fan 42 after absorbing the heat of heat conducting pipe 32, then is flowed into by airduct row 43 in receiving space 11,
And then circulation.
In summary, combustor baking oven provided by the invention, has the advantages that：
1) it is simple in construction, internal air circulation in baking oven can be realized, improves the utilization rate of energy；
2) while by air in baking oven and flame isolation open, improve security performance.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
