In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in fig. 1 to 3: the embodiment provides an infrared gas furnace 11 of preventing tempering, including two combustors, radiation dish 1, some firearm, ejector 9, prevent tempering mechanism and furnace body 12, be provided with two combustors in the furnace body 12, one of them combustor is fixed to be set up in preventing tempering mechanism, radiation dish 1 sets up in the top of furnace body 12, the spark plug 14 of some firearm sets up in the furnace body 12 and is located the center department of two combustors, spark plug 14 is fixed in the pivot, ejector 9 is connected in the bottom of furnace body 12, ejector 9 is used for communicateing the gas.
The anti-backfire mechanism comprises a worm wheel 4, a worm 5, a rotating shaft 13 and an ignition knob 6, wherein the rotating shaft 13 penetrates through the bottom surface of the furnace body 12 and is fixedly connected with one (lower layer) burner, the worm wheel 4 is arranged at the lower end of the rotating shaft 13, the ignition knob 6 is electrically connected with a spark plug 14, the ignition knob 6 is connected onto the worm 5, and the worm wheel 4 is matched with the worm 5. The combustor and the pivot 13 fixed connection of lower floor, the combustor of upper strata pass through stationary dog 15 joint in furnace body 12, the edge of the combustor of upper strata be provided with stationary dog 15 assorted recess, the surface of two combustors is inconsistent, seamless, radiation dish 1 is fixed in on the top surface of furnace body 12. The rotating shaft 13 penetrates through a shaft barrel 16 in the furnace body 12, a rotary seal is arranged between the rotating shaft 13 and the shaft barrel 16, the top of the rotating shaft 13 is clamped with the shaft barrel 16 or the bottom of the rotating shaft 13 is clamped with the furnace body 12, so that the rotating shaft is fixed in height, a plurality of flow deflectors 7 are obliquely arranged on the shaft barrel 16, and the flow deflectors 7 are positioned in a mixing chamber 8 of the furnace body 12 below the combustor. The two burners are ceramic burners, the same air holes in one-to-one correspondence are uniformly distributed on the two ceramic burners, when the ignition knob 6 is turned off, the air holes on the two burners are completely staggered, and when the ignition knob 6 is turned on to the maximum, the air holes on the two burners are completely overlapped. When a user needs to close the heat load, the upper layer combustor 2 is fixed, the lower layer combustor 3 rotates relative to the upper layer combustor 2, at the moment, due to the fact that air holes in the two layers of combustors are staggered, the flow area of mixed air changes, and then the flow speed of the mixed air is matched with the flame propagation speed, and the purpose of preventing backfire is achieved.
The middle part of the radiation disc 1 is of a metal net pulling structure.
