Gas pipeline and air pipeline that mixer converges, the outlet of connection venturi mixer mixing tube and be connected on mixing tube
Several hollow burners, the ignitor controlled by ignition control device is equipped in the burner, the burner
Outside is evenly equipped with the air chamber plate of several strips around axis, the air chamber plate by the side wall of burner be divided into it is several have a porose area, it is described
There is the centre of porose area to offer several main stomatas in column.
Specifically, the two sides of the main stomata are also provided with secondary stomata in column.
Specifically, the burner is made of carbon steel seamless steel pipe.
Further, the both ends of the mixing tube are equipped with reinforcement block.
Specifically, the gas pipeline is equipped with gas shutoff valve, gas filter, micromanometer and gas fine-adjustment valve.
Further, gas pressure-reducing valve, high pressure switch, low-pressure switch and electromagnetism are additionally provided on the gas pipeline
Valve.
Further, there are two the solenoid valves.
Specifically, the air pipeline is equipped with air cutoff valve, air manometer and air reset valve.
Further, the air pipeline is equipped with air reducing valve and air pressure switch.
By adopting the above technical scheme, the beneficial effect of technical solution of the present invention is:
This burner will be separated into elongated gas chamber by air chamber plate on the outside of burner, leave air-fuel mixer
Uniform second-time burning is carried out after burner, and mold is allowed to obtain the heating of efficient uniform.

Specific embodiment
Invention is further described in detail combined with specific embodiments below.
Embodiment:
As shown in Figure 1 to Figure 3, a kind of rod type open fire burning device of the invention, including what is converged in venturi mixer 1
The mixing tube 4 and be connected to several on mixing tube 4 that gas pipeline 2 and air pipeline 3, connection venturi mixer 1 export
Hollow burner 5, is equipped with the ignitor (not shown) controlled by ignition control device 6 in burner 5, burner 5 it is outer
Side is uniformly distributed there are four the air chamber plate 51 of strip around axis, and the side wall of burner 5 is divided by air chamber plate 51 several has porose area (not mark
Note), there is the centre of porose area to offer several main stomatas 52 in column.The present apparatus is used by the back side that burner 5 is inserted into mold 7.
Combustion gas and air pass through gas pipeline 2 respectively and air pipeline 3 reaches venturi mixer 1 and mixed, and are then delivered to combustion
It burns in stick 5, just will do it by ignition power stage ignition and burn for the first time；The structure of burner 5 will cause four row's air-fuel mixtures
The position that body sprays, and 5 periphery of burner can be divided into elongated gas chamber by air chamber plate 51, and air-fuel mixture body encounters periphery
Air generates second-time burning, generates relatively uniform combustion flame, mold 7 is allowed to obtain the heating of efficient uniform.Because of air chamber plate
51 are intended merely to that uniform gas chamber will be divided into around burner 5, so the quantity of air chamber plate 51 can be three in practice
Block any of the above is adjusted, and the shape of air chamber plate 51 can also be not limited to the slab construction in embodiment.
As shown in figure 3, the two sides of main stomata 52 are also provided with secondary stomata 53 in column.Under identical flow, secondary stomata 53
Presence can reduce the bore of main stomata 52, increase through resistance, such air-fuel mixture body can be more uniformly from combustion
The surrounding for burning stick 5 is overflowed, and the uniformity of burning is promoted.
Burner 5 is made of carbon steel seamless steel pipe.Burner 5 has certain coefficient of expansion, it is not easy to deform, so relatively
It can guarantee the uniformity burnt under long-term work.
As shown in Fig. 2, the both ends of mixing tube 4 are equipped with reinforcement block 41a, 41b.Reinforcement block 41a, 41b are as burner
Support member between primary combustion part and mold 7 prevents it from relative position movement occurs with mold 7 and causes burning uneven
Even problem.
As shown in Figure 1, gas pipeline 2 is equipped with gas shutoff valve 21, gas filter 22, micromanometer 26 and combustion gas fine tuning
Valve 29.The above structure makes gas pipeline 2 have the function of basic control on-off, filtering, measurement and adjusting.
As shown in Figure 1, being additionally provided with gas pressure-reducing valve 23, high pressure switch 24, low-pressure switch 25 and two on gas pipeline 2
A solenoid valve 27,28.The above structure makes gas pipeline 2 have automatic regulation function, and two solenoid valves 27,28 can ensure at it
It can also be worked normally in the case where one failure.
As shown in Figure 1, air pipeline 3 is equipped with air cutoff valve 31, air manometer 34 and air reset valve 35.More than
Structure makes air pipeline 3 have the function of basic control on-off, measurement and adjusting.
As shown in Figure 1, air pipeline 3 is equipped with air reducing valve 32 and air pressure switch 33.The above structure makes air
Pipeline 3 has automatic regulation function.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
