DETAILED DESCRIPTION

[0032] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0033] Example 1:

[0034] This embodiment provides a burner gas distribution pipe, including:

[0035] The gas distribution pipe body 1 has a plurality of nozzles 2 evenly arranged at one end of the gas distribution pipe body 1, and sealing plugs 21 and mounting brackets 3 are provided at both ends of the gas distribution pipe body 1. The mounting brackets 3 are fixedly connected to the gas distribution pipe body 1, and a connecting pipe 4 is provided at the bottom of the gas distribution pipe body 1;

[0036] The air intake pipe 5 is fixedly mounted on the connecting pipe 4 and is provided with a first air intake channel 6 and a second air intake channel 7;

[0037] A fixing assembly, through which the air intake pipe 5 is detachably mounted on the connecting pipe 4;

[0038] Baffle 8: A baffle 8 is provided in the connecting pipe 4.

[0039] As can be seen from this embodiment, sealing plugs 21 and mounting brackets 3 are provided at both ends of the split pipe body 1. The mounting bracket 3 is fixedly connected to the split pipe body 1. A number of mounting holes for fixing are provided on the mounting bracket 3. A connecting pipe 4 is provided at the bottom of the split pipe body 1. The air intake pipe 5 is detachably mounted on the connecting pipe 4 through a fixing assembly. The installation and disassembly are simple. A first air intake channel 6 and a second air intake channel 7 are provided on the air intake pipe 5. The first air intake channel 6 is used to introduce fuel gas, and the second air intake channel 7 is used to introduce air or other combustion aids. The gas is fully mixed in the connecting pipe 4 and enters the split pipe body 1 through the baffle 4 provided in the connecting pipe 4, and then distributed to each nozzle 2. The air pressure at each nozzle 2 in the same cavity is roughly the same, so the gas output of each nozzle 2 is similar, thereby achieving a uniform gas distribution effect.

[0040] By adopting the combined installation method, the welding and painting processes required in the traditional installation method are avoided, thereby reducing the required process steps and reducing pollution to the environment. At the same time, the traditional installation method is welded as one, and the entire burner gas distribution pipe must be removed from the body every time it needs to be repaired. By adopting the combined installation method, only some parts need to be removed for repair, thereby achieving the effect of convenient maintenance.

[0041] Example 2:

[0042] This embodiment provides a burner gas distribution pipe, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0043] There are at least two baffles 8 , and at least two baffles 8 are spaced apart in the connecting tube 4 along an axial direction perpendicular to the connecting tube 4 , and baffle channels 9 are formed between adjacent baffles 8 and between the baffles 8 and the inner wall of the connecting tube 4 .

[0044] It can be seen from this embodiment that the baffle 8 is a plate with a bent surface. The gas that is initially mixed from the first air inlet channel 6 and the second air inlet channel 7 into the connecting pipe 4 can not only flow in the baffle channel 9 formed between the baffle 8 and the inner wall of the connecting pipe 4, but also flow in the baffle channel 9 formed between adjacent baffles 8. After the initially mixed gas collides on at least one of the two baffles 8 to form turbulence, it can also collide on the other one to form turbulence, which allows the initially mixed gas to be further mixed, thereby making the mixing effect of the fuel gas and the combustion aid better, that is, the mixing more uniform.

[0045] Example 3:

[0046] This embodiment provides a burner gas distribution pipe, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] It also includes a support frame 10, which is arranged around at least two baffles 8, and at least two baffles 8 are connected to the inner wall of the connecting pipe 4 through the support frame 10.

[0048] It can be seen from this embodiment that the baffle 8 can be directly connected to the inner wall of the connecting pipe 4, but when multiple baffles 8 are provided, the workload of connecting the multiple baffles 8 to the inner wall of the connecting pipe 4 respectively is large, and the installation operation may not be very convenient, and it is also easy to waste time.

[0049] Therefore, in another embodiment, a support frame 10 is further included. When the support frame 10 supports the at least two baffles 8, when the at least two baffles 8 are installed on the inner wall of the connecting pipe 4, the support frame 10 can be directly connected to the inner wall to achieve the purpose of installing multiple baffles 8 into the connecting pipe 4 at the same time. This setting method can reduce the workload of the operator and make it easier to install multiple baffles 8 into the connecting pipe 4. At the same time, the operator spends less time.

[0050] Optionally, the connection between the baffle 8 and the support frame 10 and the connection between the support frame 10 and the inner wall of the connecting pipe 4 can be welding. Of course, the embodiment of the present application does not impose any specific limitation on this.

[0051] Optionally, in order to make each baffle 8 more stably arranged in the connecting pipe 4, that is, to better support each baffle 8, a reinforcement frame 22 may also be included. The support frame 10 and the reinforcement frame 22 are both arranged around the at least two baffles 8 mentioned above. The support frame 10 and the reinforcement frame 22 are arranged in sequence in the height direction of the baffle 8, and the at least two baffles 8 mentioned above are connected to the inner wall through the support frame 10 and the reinforcement frame 22. Through this arrangement, each baffle 8 can be more stably arranged on the inner wall of the connecting pipe 4 to function more stably.

[0052] Example 4:

[0053] This embodiment provides a burner gas distribution pipe, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0054] It also includes a support rod 11, which passes through the baffle 8 along the thickness direction of the baffle 8 and is connected to the support frame 10.

[0055] It can be seen that this embodiment also includes a support rod 11, which passes through the baffle 8 along the thickness direction of the baffle 8 and is connected to the support frame 10, that is, the part between the two ends of the baffle 8 is hung on the support frame 10 through the support rod 11, so that the support rod 11 and the support frame 10 can jointly support the baffle 8, so that the shape of the baffle channel 9 is not easily deformed, and thus it is not easy to affect the flow rate of the mixed gas.

[0056] Optionally, the number of support rods 11 may be one. However, to better prevent deformation of the baffle 8, in another embodiment, the number of support rods 11 is at least two, and the at least two support rods 11 both pass through the baffle 8 along the thickness direction of the baffle 8 and are connected to the support frame 10. The at least two support rods 11 are spaced apart so that more parts of the baffle 8 can be supported, thereby better preventing deformation of the baffle 8.

[0057] Example 5:

[0058] This embodiment provides a burner gas distribution pipe, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] The fixed components include:

[0060] A plurality of through cavities 12 are provided and are evenly distributed around the inside of the air inlet pipe 5;

[0061] The mounting groove 13 passes through one end of the connecting pipe 4 and extends inwardly to the air inlet pipe 5. The mounting groove 13 communicates with the through cavity 12;

[0062] A first spring insert rod 14, which is disposed in the mounting groove 13;

[0063] The chute 15 is longitudinally formed on the air inlet pipe 5 and communicates with the through cavity 12;

[0064] A second spring rod 16, which is slidably connected to the slide groove 15;

[0065] The plug 17 is located in the through cavity 12 and is fixedly connected to the end of the second spring rod 16 where the spring is not provided;

[0066] A limiting slot 18 is provided on the side wall of the end of the first spring rod 14 where no spring is provided, and the lower end of the plug 17 is inserted into the limiting slot 18 .

[0067] It can be seen from this embodiment that when installing the intake pipe 5, first press the second spring rod 16 inward, then insert the first spring rod 14, and when the limiting slot 18 is rotated to the appropriate position, release the first spring rod 14. At this time, the plug 17 is inserted into the limiting slot 18, and the structural connection is tightened. When disassembly is required, just squeeze the second spring rod 16 to disengage the plug 17 from the limiting slot 18. At this time, pull out the first spring rod 14 to complete the structural disassembly. When the intake pipe 5 is damaged, it can be disassembled and replaced separately.

[0068] Example 6:

[0069] This embodiment provides a burner gas distribution pipe, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0070] A sealing ring 19 is provided between the connecting pipe 4 and the air intake pipe 5 .

[0071] It can be seen from this embodiment that a sealing ring 19 is provided between the connecting pipe 4 and the air inlet pipe 5 to prevent gas leakage.

[0074] A thickening strip 20 is integrally formed at one end of the gas distribution pipe body 1 , and a plurality of nozzles 2 are arranged on the thickening strip 20 .

[0075] It can be seen from this embodiment that a thickening strip 20 is integrally formed at one end of the air distribution pipe body 1, which has high structural strength and long service life. The length of the thickening strip 20 is smaller than the length of the air distribution pipe body 1. The thickening strip 20 is provided to ensure that the nozzle 2 is firmly installed.

[0076] Example 8:

[0077] This embodiment provides a burner gas distribution pipe, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
