Detailed description of the invention
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the present embodiment comprises combustion tube 5, plate 1 of igniting, fireguard 3, fire row support 2, fixed support 4, air door 8, fly net 7, screw 6, thermocouple 9, ignition electrode 10, card 11, fireguard 3, air door 8 are arranged on combustion tube 5, and combustion tube 5 is provided with fire output hole 51, and described combustion tube 5 is arranged with fire row support 2 split, combustion tube 5 one end is connected with external feed stream pipe, and the other end is connected with fire row support 2.Because combustion tube 5 and fire row support 2 split are arranged, fire row support 2 is bent into again after being flattened combustion tube 5 front end, ensure that the length of combustion tube 5, quantity and the heat radiation area of fire output hole 51 on combustion tube 5 can be ensured, effectively improve the efficiency of fuel gas oven or gas burning roastor entirety.
Preferably, described fire row support 2 is provided with the boss 21 be inserted in combustion tube 5, the cross section of boss 21 is circular, fire row support 2 is clamped with fixture during installation, boss 21 is filled in combustion tube 5, make the outer wall of boss 21 and the inwall close contact of combustion tube 5, then the junction of boss 21 with combustion tube 5 is welded, one end of combustion tube 5 is sealed by boss 21.Although need the fire row support 2 that die sinking manufacture is again independent, fire row support 2 structure is simple, and relative to prior art, combustion tube 5 being flattened rear bending can not increase cost, and can ensure the sealing between combustion tube 5 and fire row support 2.
Further, described combustion tube 5 is provided with vent 52, and vent 52 is for being guided out mutually lighting between fire hole 51.The both sides of combustion tube 5 bottom are equipped with a discharge fire hole 51; but because ignition electrode 10 is positioned at the side of combustion tube 5; the phenomenon that the fire output hole 51 that often there will be combustion tube 5 both sides can not be lighted fast simultaneously, increases vent 52, whole fire output holes 52 can be impelled to light fast.Referring to Fig. 2, vent 52 in the present embodiment is arranged on one end that combustion tube 5 is connected with fire row support 2, and along the distribution of combustion tube 5 circumferencial direction, vent 52 is also arranged on the periphery of fire output hole 51, can more be convenient to mutually lighting between fire output hole 51 simultaneously.
Preferably, the area of described vent 52 is less than or equal to the area of described fire output hole 51, is convenient to processing.
Further, also comprise the arc-shaped being arranged on combustion tube 5 bottom to ignite plate 1, ignite between plate 1 and combustion tube 5 and leave gap, plate 1 of igniting described in the present embodiment is provided with recess 12 not of uniform size, recess 12 is distributed in both sides and the middle part of plate of igniting, make to ignite between plate 1 and burner 5 and leave space, the recess 12 in the utility model comprises the structures such as concave station, groove, concave point, as long as described recess 12 indent can make to ignite between plate 1 and combustion tube 5 form space.After combustion tube 5 leads to combustion gas, there is the mist of combustion gas and air gap, when ignition electrode 10 is lighted a fire, as long as there is a fire output hole 51 to be lighted, combustion tube 5 and mist between plate 1 of igniting just can burn rapidly, by igniting plate thus make the whole conflagration of the fire hole of whole fire row, avoiding burning insufficient, effectively improve efficiency of combustion.
Particularly, described plate 1 of igniting is arranged on combustion tube 5 by the mode of welding or planting weldering screw, and structure is simple, be convenient to processing.
Also comprise the fixed support 4 be arranged on combustion tube 5, fixed support 4 is provided with the installing hole of two stationary heat galvanic couples 9 and the fixing hole of two fixed ignition pins 10.In prior art, the mounting bracket of ignition electrode 10 and thermocouple 9 or be fixed on thermal insulation board, the yielding location that causes is inaccurate; Or to be fixed on combustion tube 5 but to only have an ignition electrode fixing hole and a thermocouple fixing hole, causing ignition electrode 10 and thermocouple 9 easily off normal, fixing not firm.The fixed support 4 one-tenth wing of the present utility model, middle part is welded on combustion tube 5, ignition electrode 10 and thermocouple 6 is made to be distributed in combustion tube 5 both sides, respectively by two fixing holes, the two ends of ignition electrode 10 with thermocouple 9 are fixed, card 11 is for by ignition electrode 10 and thermocouple 9 and fixed support 4 first installing hole clampings, ignition electrode 10 and thermocouple 9 and fixed support 4 second installing hole nuts are connected, and this structure makes that fixed support 4 is not yielding, ignition electrode 10 and thermocouple 9 accurate positioning, not easily off normal.
Preferably, described combustion tube 5 is provided with into air scoop, air door 8 and screw 6 enter air capacity for regulating burner first time, enter air scoop place and fly net 7 is installed, described fly net 7 is made up of stainless steel material, installing fly net 7 can prevent insect or foreign material from entering in combustion tube 5, can effectively avoid the nozzle of burner or fire hole to block the abnormal combustion caused.
Referring to Fig. 5,6, because gas burning roastor or baking oven can comprise upper burner and lower burner as required simultaneously, also only can there is upper burner or only have lower burner, Fig. 5 is the structure chart that burner of the present utility model is arranged on thermal insulation board, and Fig. 6 is the structure chart that burner of the present utility model is arranged on lower thermal insulation board.
