[0027] Example

[0028] Reference Figure 1 and Figure 2 The utility model proposes a low-cost multi-channel double-dividing symmetrical multi-head burner, comprising: a gas distributor 10, a central nozzle 20 and an outer ring nozzle 30;

[0029] The air distribution seat 10 is provided with a central air supply cavity 40 and an outer ring air supply cavity 50; the outer ring air supply cavity 50 is arranged around the outer periphery of the central air supply cavity 40; the central air supply seat 11 is arranged above the central air supply cavity 40;

[0030] A plurality of outer ring air supply channels 60 are arranged on the outer periphery of the outer ring air supply cavity 50, and the outer ring air supply channel 60 includes a first air supply section 61 and a second air supply section 62; the second air supply sections 62 of the plurality of outer ring air supply channels 60 are arranged at intervals on the outer periphery of the outer ring air supply cavity 50; the first air supply section 61 extends outward from the outer ring air supply cavity 50 and is connected to the middle of the second air supply section 62;

[0031] The second air supply section 62 is provided with a plurality of outer ring air supply seats 12 at intervals; the central nozzle 20 and the outer ring nozzle 30 are cap-shaped structures made of metal sheets, which can be tightly fitted and fixed to the central air supply seat 11 and the outer ring air supply seat 12 respectively.

[0032] In the utility model, the gas distributor 10 is installed at the gas outlet of the burner, and part of the gas of the burner is sent to the central gas supply cavity 40, and the other part is sent to the outer ring gas supply cavity 50; the outer ring gas forms a mixed effect in the outer ring gas supply cavity 50, and then is sent outward to the outer ring gas supply seat 12 through the outer ring gas supply channel 60 on the periphery, and then sent to the outer ring nozzle 30; wherein, the gas of the first gas supply section 61 flows outward and diffuses to the second gas supply section 62, and can flow toward the two ends of the second gas supply section 62 in a diverted and diffused manner, and is supplied upward through the outer ring nozzle 30, effectively improving the gas mixing rate. In addition, the central nozzle 20 and the outer ring nozzle 30 are cap-shaped structures formed by flat metal sheets, which are pressed onto the gas supply seat by pressing and fitting to form an integrated burner structure, which can effectively reduce the overall weight of the burner and reduce production costs.

[0033] In this embodiment, the first gas supply section 61 and the second gas supply section 62 are arranged in a symmetrical "T"-shaped structure. The symmetrical "T"-shaped structure allows the outer ring gas to be evenly distributed to both ends when the second gas supply section 62 is output, so that the outer ring nozzles 30 at both ends can obtain uniform gas supply output.

[0034] In this embodiment, four outer ring air supply channels 60 are provided.

[0035] Specifically, a single outer ring gas supply channel 60 is provided with two outer ring nozzles 30, and the two outer ring nozzles 30 are respectively arranged at the ends of both ends of the outer ring gas supply channel 60. The two outer ring nozzles 30 are arranged at the ends of the second gas supply section 62 arranged in a symmetrical "T"-shaped structure, so that the gas can be evenly diverted and fully mixed, and then output from the ends through the outer ring nozzles 30, and the gas output effect is uniform and stable.

[0036] The four outer ring air supply channels 60, each with two outer ring nozzles 30, can form a combustion effect of a 9-head multi-head burner.

[0037] In this embodiment, the first gas supply section 61 is tilted upward toward one end of the second gas supply section 62. The tilted first gas supply section 61 can flow along the direction of the upward flow of the burner gas, and tilt the second gas supply section 62 on the outer side to supply gas, so that the gas flow is smoother and local turbulence is not easy to occur. The gas output of the outer ring nozzle 30 is stable, and the flame burns stably and is not easy to shake.

[0038] Specifically, the bottom plate wall of the first gas supply section 61 and the bottom plate wall of the second gas supply section 62 are connected to the bottom shell wall 13 structure; the bottom shell wall 13 is inclined upward toward one side of the second gas supply section 62. The continuous and integrated bottom shell wall 13 structure facilitates the upwardly inclined gas supply of the outer ring gas supply channel 60, and also facilitates mold casting.

[0039] In this embodiment, the central nozzle 20 and the outer ring nozzle 30 are made of stainless steel sheet metal. The nozzle structure made of flat stainless steel sheet metal has strong corrosion resistance, low weight, and is easy to be pressed and fixed on the fixing seat.

[0040] Preferably, the plate thickness of the central nozzle 20 and the outer ring nozzle 30 is in the range of 0.4 mm to 0.8 mm, for example, the plate thickness is 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm or 0.8 mm.
