Description

Technical Field

[0001] The invention belongs to the technical field of burners and relates to an alternate-row segmented burner. Background Art

[0002] In the application scenarios of burners, whether in the fields of industrial heating, household gas equipment or commercial kitchen appliances, different working conditions have diverse requirements for the heating power adjustment range of the burner. Most traditional burners adopt a single combustion mode or a limited number of fixed combustion modes, which cannot flexibly adapt to complex and changing usage scenarios. For example, in industrial production, different processing stages may require different heating powers, and traditional burners are difficult to accurately match, resulting in increased energy consumption and reduced production efficiency; in household gas equipment, different fire powers are also required when cooking different foods. Traditional burners cannot achieve fine adjustment, which affects the cooking effect. In addition, since the number of combustion holes cannot be effectively controlled, in low-power operation, it is easy for the gas to burn incompletely, causing environmental pollution and energy waste. Therefore, there is an urgent need to develop a staggered burner that can flexibly adjust the number of working combustion holes and widen the heating power adjustment range.

[0003] In order to overcome the shortcomings of the existing technology, people have proposed various solutions through continuous exploration. For example, a Chinese patent discloses an atmospheric segmented burner and hot water equipment [application number: 202023313891.6]. During use, the gas is ejected through the nozzle, and the surrounding air is sucked into the ejector for mixing; then it is injected into the ejection port by the ejector and flows into the mixing tank. The gas entering the mixing tank is mixed again, so that the gas and air are fully mixed, and the uniformity of the mixed gas is improved. After mixing, the gas flows into the flow-equalizing cavity through the flow-equalizing hole, and then flows from the flow-equalizing cavity to the fire hole, so that the mixed gas flows out of the surface of the burner body for ignition. However, during use, this solution still cannot flexibly adjust the number of working combustion holes and widen the heating power adjustment range, and has the defect of high energy consumption.

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, a staggered burner includes a igniter main body 1 and a burner distribution pipe 2, wherein the burner distribution pipe 2 has two parallel channels 3 for connecting to the outside air, one end of the channel 3 is connected to the first nozzle part 4, the second nozzle part 5 and the third nozzle part 6, and the other end is connected to the first air inlet part 7, the second air inlet part 8 and the third air inlet part 9, the igniter main body 1 and the burner distribution pipe 2 are connected by a connector 10, the igniter main body 1 is composed of a first combustion plate group 11, a second combustion plate group 12 and a third combustion plate group 13 arranged parallel to each other, the first nozzle part 4 corresponds to the first air inlet part 7 and the first combustion plate group 11, the second nozzle part 5 corresponds to the second air inlet part 8 and the second combustion plate group 12, and the third nozzle part 6 corresponds to the third air inlet part 9 and the third combustion plate group 13.

[0027] In this embodiment, the burner distribution pipe 2 serves as the core component for gas and air transmission of the entire burner. The two parallel channels 3 inside are responsible for transporting air to the corresponding nozzle parts. The first air inlet part 7, the second air inlet part 8 and the third air inlet part 9 introduce external air into the channel 3, and the channel 3 then transmits the air to the first nozzle part 4, the second nozzle part 5 and the third nozzle part 6. The ignition source body 1 is installed above the burner distribution pipe 2 through the connecting piece 10. The first combustion plate group 11, the second combustion plate group 12 and the third combustion plate group 13 are arranged in parallel. Each plate group corresponds to the nozzle part and the air inlet part at the corresponding position, forming an independent and coordinated combustion unit, realizing the orderly distribution of gas and air, and laying the foundation for the realization of different combustion modes. By cooperating with the corresponding combustion plate groups through three independent air intake paths, the number of combustion plates participating in the combustion can be flexibly controlled, thereby realizing the preliminary adjustment of the combustion power to meet the heating requirements in different scenarios.

[0028] Combine Figure 1-4As shown, the first combustion plate group 11 includes two first combustion plates 14 , the two first combustion plates 14 are parallel to each other, and the first combustion plates 14 are connected to the first nozzle part 4 .

[0029] Specifically, two mutually parallel first combustion plates 14 constitute a first combustion plate group 11, which are connected to the first nozzle part 4 through a pipe or a connecting structure. The first nozzle part 4 conveys the mixture of gas and air to the first combustion plate 14. The first combustion plate 14 is provided with a combustion hole, and the mixed gas is ejected from the combustion hole and burned. The two first combustion plates 14 form a basic combustion unit, providing a stable combustion surface. In low-power combustion mode, only turning on the first combustion plate group 11 can meet the needs, achieving energy saving and precise heating. At the same time, the parallel arrangement of the first combustion plates 14 makes the combustion more uniform and improves the combustion effect.

[0030] The first nozzle unit 4 includes two first nozzles 15 provided on the burner distribution pipe 2. The first nozzles 15 are connected to the first combustion plate 14 via a connecting valve. The two first combustion plates 14 are parallel to each other.

[0031] In this embodiment, two first nozzles 15 are installed on the burner distribution pipe 2 and are connected to the channel 3 to guide the gas and air mixture in the channel 3. The first nozzle 15 is connected to the first combustion plate 14 through a connecting valve. The connecting valve can control the on and off of the mixed gas. When the connecting valve is open, the mixed gas enters the first combustion plate 14 from the first nozzle 15; when it is closed, the supply of mixed gas is cut off. The setting of the connecting valve realizes the precise control of whether the first combustion plate group 11 burns or not, thereby realizing the switching of different combustion modes. When low-power operation is required, the connecting valve is opened to make the first combustion plate group 11 work; when not needed, it is closed to avoid gas waste. At the same time, the two first nozzles 15 ensure that the mixed gas is evenly distributed to the two first combustion plates 14, ensuring combustion stability.

[0032] Combine Figure 1 、 Figure 4 As shown, the first air intake portion 7 includes a first air intake port 16 and a first air intake pipe 17 provided at the bottom of the burner distribution pipe 2 , and the first air intake pipe 17 is connected to the channel 3 .

[0033] In this embodiment, the first air inlet 16 is arranged at the bottom of the burner distribution pipe 2, and the outside air enters the first air inlet pipe 17 through the first air inlet 16. The first air inlet pipe 17 introduces air into the channel 3 in the burner distribution pipe 2, providing the oxygen required for gas combustion, ensuring that the air can enter the combustion system stably and smoothly, providing sufficient oxygen for the combustion of the first combustion plate group 11, and ensuring sufficient combustion. At the same time, the independent first air inlet part 7 corresponds to the first combustion plate group 11, so that when adjusting the operation of the first combustion plate group 11, its air intake can be accurately controlled to optimize the combustion effect.

[0034] The second combustion plate group 12 includes three second combustion plates 18 . The three second combustion plates 18 are parallel to each other. The second combustion plates 18 are connected to the second nozzle portion 5 .

[0035] In this embodiment, three mutually parallel second combustion plates 18 constitute the second combustion plate group 12, which are connected to the second nozzle part 5 through a pipe or a connecting structure. The second nozzle part 5 transports the gas and air mixture to the second combustion plate 18, and the combustion holes on the second combustion plate 18 spray the mixture out for combustion. The three second combustion plates 18 increase the combustion area. In the medium power combustion mode (the first combustion plate group 11 and the second combustion plate group 12 work together), it can provide greater combustion power to meet more scene requirements. The parallel setting ensures the uniformity and stability of combustion, and at the same time works in coordination with the first combustion plate group 11 to achieve a step-by-step adjustment of the combustion power.

[0036] Combine Figure 1 、 Figure 4 As shown, the second nozzle unit 5 includes three second nozzles 19 provided on the burner distribution pipe 2. The second nozzles 19 are connected to the second combustion plate 18 via a connecting valve. The three second nozzles 19 are parallel to each other.

[0037] In this embodiment, three second nozzles 19 are installed on the burner distribution pipe 2 and are connected to the channel 3 to discharge the gas and air mixture in the channel 3. Each second nozzle 19 is connected to the corresponding second combustion plate 18 through a connecting valve. The connecting valve controls the on and off of the mixed gas to achieve independent control of the combustion of each second combustion plate 18. The combination of the connecting valve and the three second nozzles 19 not only realizes the control of whether the second combustion plate group 12 is burning as a whole, but also can control a single second combustion plate 18, further refining the combustion mode adjustment. Under different power requirements, different numbers of second combustion plates 18 can be flexibly opened to achieve more precise power adjustment, while ensuring uniform distribution of the mixed gas and improving combustion stability.

[0038] The second air intake portion 8 includes a second air intake port 20 and a second air intake pipe 21 provided at the bottom of the burner distribution pipe 2 . The second air intake pipe 21 is connected to the channel 3 .

[0039] In this embodiment, the second air inlet 20 is arranged at the bottom of the burner distribution pipe 2, and the outside air enters the second air inlet pipe 21 through the second air inlet 20. The second air inlet pipe 21 introduces air into the channel 3 to provide oxygen for the combustion of the second combustion plate group 12. The independent second air inlet part 8 corresponds to the second combustion plate group 12, ensuring the air supply required for the combustion of the second combustion plate group 12, so that the combustion is sufficient. When adjusting the working state of the second combustion plate group 12, its air intake volume can be accurately controlled, and it works in coordination with the first air inlet part 7 to achieve precise adjustment of the overall air intake volume under different combustion modes and optimize combustion efficiency.

[0040] Combine Figure 1-4 As shown, the third combustion plate group 13 includes six third combustion plates 22 , which are parallel to each other, and the third combustion plates 22 are connected to the third nozzle part 6 .

[0041] In this embodiment, six mutually parallel third combustion plates 22 form a third combustion plate group 13, which are connected to the third nozzle part 6 through a pipe or a connecting structure. The third nozzle part 6 transports the gas and air mixture to the third combustion plate 22, and the combustion holes on the third combustion plate 22 spray the mixture for combustion. The six third combustion plates 22 greatly increase the combustion area. In the high-power combustion mode (the first combustion plate group 11, the second combustion plate group 12 and the third combustion plate group 13 work together), they can provide powerful combustion power to meet high-load heating requirements. The parallel setting ensures the uniformity and stability of large-area combustion, and cooperates with the first and second combustion plate groups to achieve comprehensive coverage and flexible adjustment of combustion power from low to high.

[0042] Combine Figure 1-4 As shown, the third nozzle portion 6 includes six third nozzles 23 arranged on the burner distribution pipe 2, and the third nozzles 23 are connected to the third combustion plate 22 through a connecting valve. The six third nozzles 23 are parallel to each other, and the third air intake portion 9 includes a third air inlet 24 and a third air intake pipe 25 arranged at the bottom of the burner distribution pipe 2, and the third air intake pipe 25 is connected to the channel 3.

[0043] In this embodiment, six third nozzles 23 are installed on the burner distribution pipe 2 and are connected to the channel 3 to discharge the gas and air mixture in the channel 3. Each third nozzle 23 is connected to the corresponding third combustion plate 22 through a connecting valve to control the on and off of the mixed gas. The third air inlet 24 is set at the bottom of the burner distribution pipe 2. The outside air enters the third air inlet pipe 25 through the third air inlet 24 and is then introduced into the channel 3 to provide oxygen for the combustion of the third combustion plate group 13. The combination of the six third nozzles 23 and the connecting valve realizes independent control of each combustion plate of the third combustion plate group 13. Combined with the control structure of the first and second combustion plate groups, it can realize a combination of multiple different combustion modes, greatly broadening the power adjustment range of the burner. The independent third air inlet part 9 ensures that there is sufficient air when the third combustion plate group 13 burns, and works in coordination with other air inlet parts to ensure that the best combustion effect can be achieved under different combustion modes.

[0044] Combine Figure 1-4 As shown, the connecting member 10 includes a connecting bracket 26 arranged between the ignition divider body 1 and the burner distribution pipe 2, and the burner distribution pipe 2 is provided with a fixed screw profile 27 at one end away from the ignition divider body 1, and the ignition divider body 1 is provided with a dirt shielding baffle 28 and a damper fixing plate 29, and the ignition divider body 1 is located above the burner distribution pipe 2.

[0045] In this embodiment, the connecting bracket 26 connects the ignition divider body 1 and the burner distribution pipe 2, playing a supporting and fixing role, so that the ignition divider body 1 is firmly installed above the burner distribution pipe 2, and the fixed screw profile 27 is used to fix the burner as a whole on other equipment. The dirt shielding baffle 28 is installed on the ignition divider body 1 to prevent external impurities from entering the burner; the damper fixing plate 29 is used to install the adjusting damper, and the amount of air entering the burner is controlled by adjusting the damper. The connecting bracket 26 and the fixed screw profile 27 ensure the stability of the burner structure and the convenience of installation. The dirt shielding baffle 28 effectively protects the internal structure of the burner, reduces the impact of impurities on combustion, and extends the service life of the burner. The damper fixing plate 29 facilitates users to adjust the air intake according to actual needs, optimize the combustion effect, and further improve the adaptability and energy saving of the burner.

[0046] The working principle of the present invention is:

[0047] The alternate-row segmented burner of the present invention has three air inlet pipes (corresponding to the first air inlet part 7, the second air inlet part 8, and the third air inlet part 9) and 11 fire rows (composed of two first combustion plates 14, three second combustion plates 18, and six third combustion plates 22), which can realize three combustion modes. The first combustion plate 14, the second combustion plate 18, and the third combustion plate 22 are each provided with a mixing flow channel, a connecting cavity, and a mixing cavity. The specific working steps are as follows:

[0048] 2-row fire combustion mode (low power mode): When the equipment is in a low-power heating demand scenario, it is only necessary to start the first combustion plate group 11, and the gas enters the first air inlet pipe 17 from the first air inlet 16. Since the first air inlet pipe 17 is connected to the channel 3 in the burner distribution pipe 2, the gas is transmitted to the first nozzle part 4 along the channel 3. At this time, the operator opens the connecting valve between the first nozzle 15 and the first combustion plate 14, and the mixed gas enters the first combustion plate 14 through the connecting valve. Inside the first combustion plate 14, the mixed gas first enters the mixing flow channel, and the mixed flow The special structural design of the channel can initially guide and mix the gas and air. Then, the mixed gas enters the connecting chamber, which plays a transition and buffering role, allowing the gas to be further evenly distributed. Finally, the mixed gas reaches the mixing chamber. In the mixing chamber, the gas and air are fully mixed to form a uniform and stable combustible mixed gas. After the mixing is completed, the combustible mixed gas is ejected from the combustion holes on the surface of the first combustion plate 14 and ignited. The two first combustion plates 14 work at the same time to form two rows of fire combustion, thereby outputting low-power heat to meet low-intensity heating needs.

[0049] 5-row fire row combustion mode (medium power mode): When medium power heat output is required, the system starts the first combustion plate group 11 and the second combustion plate group 12 at the same time. The working process of the first air intake part 7 is the same as that in low power mode. The gas passes through the first air inlet 16, the first air inlet pipe 17, the channel 3, the first nozzle part 4, and enters the first combustion plate 14 through the opened connecting valve to complete combustion. At the same time, the second air intake part 8 starts to work, and the external gas enters the second air inlet pipe 21 from the second air inlet 20, and is then transmitted along the channel 3 to the second nozzle part 5. The operator opens the connecting valve between the second nozzle 19 and the second combustion plate 18, and the mixed gas enters the second combustion plate 18. The second combustion plate 18 is also provided with a mixing flow channel, a connecting chamber and a mixing chamber. The mixed gas passes through these structures in turn, is fully mixed, and then is ejected from the combustion hole for combustion. The three second combustion plates 18 and the two first combustion plates 14 work together to form 5-row fire row combustion, so that the burner outputs medium power heat to meet the medium intensity heating requirements.

[0050] 11 rows of fire rows combustion mode (high power mode): In the high power heating scenario, the first air inlet part 7, the second air inlet part 8 and the third air inlet part 9 operate at the same time, and the gas delivery and combustion process of the first air inlet part 7 and the second air inlet part 8 are consistent with the above mode. The gas of the third air inlet part 9 enters the third air inlet pipe 25 from the third air inlet port 24, and is then transmitted to the third nozzle part 6 through the channel 3. After opening the connecting valve between the third nozzle 23 and the third combustion plate 22, the mixed gas enters the third combustion plate 22. The mixing flow channel, connecting chamber and mixing chamber in the third combustion plate 22 fully mix the mixed gas, and then the mixed gas is ejected from the combustion hole and burned. The six third combustion plates 22, the three second combustion plates 18 and the two first combustion plates 14 are all put into work, and the 11 rows of fire rows burn at the same time, generating a large amount of heat, achieving high power output, and meeting high-intensity heating requirements.

[0051] In addition, during the entire combustion process, the operator can install and adjust the damper through the damper fixing plate 29 on the ignition distributor body 1. By changing the opening of the damper, the amount of air entering the channel 3 in the burner distribution pipe 2 can be accurately controlled, and the mixing ratio of gas and air can be adjusted. Regardless of the combustion mode, the damper can be adjusted to ensure full combustion of the gas, improve combustion efficiency, reduce energy consumption and harmful gas emissions. At the same time, the dirt shielding baffle 28 can effectively block external dust, impurities, etc. from entering the burner, preventing these foreign objects from affecting the patency of the combustion hole and the mixing effect of gas and air, thereby ensuring long-term stable and efficient operation of the burner.
