[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-2 A burner for a natural gas heating furnace includes a connecting pipe 1, a fusion pipe 2, an adjusting mechanism 5, a flange pipe 7, and a sealing mechanism 8, wherein:

[0025] The fusion pipe 2 is slidably and sealed to one end of the connecting pipe 1. The fusion pipe 2 is used for mixing natural gas and air. The fusion pipe 2 has an outlet 3 for discharging the gas inside the fusion pipe 2. A sealing gasket 4 is fixedly connected inside the fusion pipe 2. The sealing gasket 4 is used to seal the gap between the fusion pipe 2 and the connecting pipe 1. The sealing gasket 4 is in contact with the connecting pipe 1. An adjustment mechanism 5 for adjusting the position of the fusion pipe 2 is connected to the connecting pipe 1. An air inlet pipe 6 is connected to the upper end of the connecting pipe 1. The air inlet pipe 6 is used to introduce air into the connecting pipe 1. A flange pipe 7 is connected to the other end of the connecting pipe 1. The flange pipe 7 is used to connect to an external heating furnace. A sealing mechanism 8 is sleeved on the flange pipe 7. The sealing mechanism 8 is used to improve the sealing effect between the flange pipe 7 and the heating furnace.

[0026] The sealing mechanism 8 includes a movable frame 81, a mounting block 82, a groove 83, a second spring 84, a movable ring 85, and a sealing ring 86. The movable frame 81 is slidably fitted onto the flange pipe 7. The mounting block 82 is fixedly connected to the inner ring of the movable frame 81 and is used to install and fix the movable frame 81. The groove 83 is opened on the movable frame 81 and is used to install the second spring 84. One end of the second spring 84 is fixedly connected to the groove 83 and is used to elastically support the movable ring 85. The other end of the second spring 84 is fixedly connected to the movable ring 85 and is used to install the sealing ring 86. The movable ring 85 cooperates with the groove 83. The sealing ring 86 is fixedly connected to the movable ring 85 and is used to seal the gap between the movable ring 85 and the heating furnace. The sealing ring 86 is a rubber ring.

[0027] The adjusting mechanism 5 includes a fixing block 51, a fixing ring 52, a first spring 53, a threaded rod 54, and a fixing nut 55. The fixing block 51 is fixedly connected to the fusion tube 2 and is used to install the threaded rod 54. The fixing ring 52 is fixedly connected to the connecting tube 1. One end of the first spring 53 is fixedly connected to the fixing block 51, and the other end of the first spring 53 is fixedly connected to the fixing ring 52. One end of the threaded rod 54 is fixedly connected to the fixing block 51, and the other end of the threaded rod 54 passes through the first spring 53 and the fixing ring 52 in sequence. The other end of the threaded rod 54 is fixedly connected to the fixing nut 55. When the fixing nut 55 is rotated, the threaded rod 54 moves in the horizontal direction. The threaded rod 54 drives the fusion tube 2 to move through the fixing block 51, adjusting the position of the fusion tube 2. After the fusion tube 2 moves, it squeezes the first spring 53. The first spring 53 generates elastic force after being compressed, and the first spring 53 generates elastic force to push the fusion tube 2.

[0028] Working process: Rotate the fixing nut 55. After the fixing nut 55 rotates, the threaded rod 54 moves in the horizontal direction. The threaded rod 54 drives the fusion tube 2 to move through the fixing block 51. Adjust the position of the fusion tube 2. After the position of the fusion tube 2 is determined, stop rotating the fixing nut 55. The flange tube 7 is fixed to the heating furnace by bolts. The bolts pass through the mounting block 82 and fix the mounting block 82. The mounting block 82 fixes the movable frame 81. The movable frame 81 elastically compresses the movable ring 85 through the second spring 84. The movable ring 85 contacts the heating furnace through the sealing ring 86. The sealing ring 86 improves the sealing effect between the movable ring 85 and the heating furnace.

[0029] Example 2

[0030] When natural gas and air enter the fusion pipe 2, the natural gas and air do not mix, thus affecting the combustion efficiency of the natural gas. (Refer to...) Figure 1-3As another preferred embodiment of the present invention, based on embodiment 1, it further includes a mixing mechanism 9 for mixing natural gas and air. The mixing mechanism 9 includes a first fixed seat 91, a rotating shaft 92 and a plurality of fan plates 93. The first fixed seat 91 is fixedly connected to the connecting pipe 1.

The plurality of fan plates 93 are equally spaced along the axis of the rotating shaft 92. During the flow of gas in the connecting pipe 1, the gas impacts the fan plates 93, and the fan plates 93 rotate around the rotating shaft 92. After the fan plates 93 rotate, they mix the gas in the connecting pipe 1.

[0031] Example 3

[0032] The gas inside connecting pipe 1, after being mixed, cannot be quickly discharged from outlet 3. (Refer to...)

The other end of the guide tube 102 is in contact with the inner wall of the connecting tube 1. The guide plate 103 is fixedly connected to the guide tube 102 and is used to guide the mixed gas into the guide tube 102.

[0033] Example 4

[0034] Air is introduced into connecting pipe 1 through intake pipe 6. The air enters connecting pipe 1 vertically and collides with the inner wall of connecting pipe 1. The air then veers back, affecting the introduction of natural gas. (Refer to...) Figure 1-4 As another preferred embodiment of the present invention, based on embodiment 1, it further includes a gas dispersion mechanism 11 for dispersing the air entering the connecting pipe 1. The gas dispersion mechanism 11 includes a hollow ring frame 111, an opening 112, and a plurality of gas outlet pipes 113. The hollow ring frame 111 is fixedly connected to the connecting pipe 1. The opening 112 is opened on the hollow ring frame 111. The plurality of gas outlet pipes 113 are evenly distributed along the axial direction of the hollow ring frame 111. Air enters the opening 112 through the air inlet pipe 6 and enters the hollow ring frame 111 through the opening 112. The air in the hollow ring frame 111 is released from the gas outlet pipes 113. The released air flows in the same direction as the natural gas, so as not to affect the introduction of natural gas.
