Detailed Implementation

[0029] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0030] like Figures 1 to 5As shown, the radially inserted axially ignited internal combustion burner of the present invention includes a main pipe 1 and a side pipe 2 that are connected to each other. A flange 3 is fixed on the main pipe 1 and a flange 4 is fixed at the end of the side pipe 2. It also includes an L-shaped air pipe 5 and a fuel pipe 6, and the air pipe 5 and the fuel pipe 6 are coaxial. The fuel pipe 6 is located outside the air pipe 5. Several supports 7 are fixed between the fuel pipe 6 and the air pipe 5 to maintain a stable distance between the fuel pipe 6 and the air pipe 5.

[0031] The air inlet ends of both fuel line 6 and air line 5 are connected to an external source via flexible hoses;

[0032] Two sealing plates 8 are also fixed between the fuel pipe 6 and the air pipe 5 to create a space for fuel flow between the fuel pipe 6 and the air pipe 5.

[0033] A flame stabilizer 9 is installed at the output end of the air pipe 5, and a number of nozzles 10 facing the flame stabilizer 9 are connected in a circular array at the output end of the fuel pipe 6. An igniter 11 facing the flame stabilizer 9 is fixed inside the main pipe 1.

[0034] Flange 3 12 is fixed on fuel pipe 6, and flange 3 12 and flange 2 4 are connected by bolts and nuts;

[0035] It also includes a moving and tilting mechanism, which is used to drive the fuel pipe 6, air pipe 5, etc. to move radially first, and then tilt them after the flame stabilizer 9 moves out of the side pipe 2.

[0036] In this embodiment, during use, the burner of the present invention is fixed by flange 3. Air pipe 5 is used for air or nitrogen flow, and fuel pipe 6 is used for gaseous fuel flow. The fuel is mixed with air in the flame stabilizer plate 9 through nozzle 10, and the fuel and air are ignited by igniter 11. When the flame stabilizer plate 9 needs to be maintained, the moving and flipping mechanism is operated to move the flame stabilizer plate 9, air pipe 5, fuel pipe 6, sealing plate 8, bracket 7, nozzle 10, etc., away from the main pipe 1 in the radial direction. After the flame stabilizer plate 9 is completely moved out of the side pipe 2, the flame stabilizer plate 9, air pipe 5, fuel pipe 6, sealing plate 8, bracket 7, nozzle 10, etc. are all flipped so that the flame stabilizer plate 9 faces upward, which makes maintenance more convenient. In addition, the air inlet ends of fuel pipe 6 and air pipe 5 are connected to the external source through hoses, so that the flame stabilizer plate 9 can be maintained without disconnecting fuel pipe 6 and air pipe 5.

[0037] The radial insertion axial ignition type internal combustion burner of the present invention has a moving and flipping mechanism including a fixed plate 13 fixed on the main pipe 1. The fixed plate 13 has an equal-length elongated hole 14 and an elongated hole 15, and an arc hole 16 communicating with the end of the elongated hole 15. The center of the arc hole 16 is concentric with the center of the end of the elongated hole 14.

[0038] The moving and flipping mechanism also includes a connecting block 17 fixed on the outer wall of the fuel pipe 6. A first moving shaft 18 and a second moving shaft 19 are fixed on the connecting block 17, and the first moving shaft 18 and the second moving shaft 19 are staggered. The first moving shaft 18 passes through the first elongated hole 14, and the second moving shaft 19 passes through the second elongated hole 15 and the arc hole 16.

[0039] The moving and flipping mechanism also includes a fixed shaft 20 rotatably mounted on a fixed plate 13. An L-shaped drive arm 21 is fixed on the fixed shaft 20. One end of the drive arm 21 has an elongated hole 3 22 through which the moving shaft 2 19 passes.

[0040] It also includes a power mechanism for rotating the drive arm 21;

[0041] In this embodiment, the principle of the moving and flipping mechanism is as follows: When the flame stabilizer 9 needs to be removed, firstly, remove the nuts and bolts connecting flange 2 4 and flange 3 12. Operate the power mechanism to make the drive arm 21 rotate clockwise around the fixed shaft 20. First, the moving shaft 1 18 moves along the elongated hole 14, and the moving shaft 2 19 moves along the elongated hole 2 15. The air pipe 5, fuel pipe 6, flame stabilizer 9 and other components move radially relative to the side pipe 2. When the moving shaft 1 18 moves to the end position of the elongated hole 14, it cannot move further. However, the drive arm 21, which continues to rotate clockwise, makes the moving shaft 2 19 continue to move along the arc hole 16, so that the connecting block 17, air pipe 5, fuel pipe 6, flame stabilizer 9 and other components rotate around the moving shaft 1 18 at this time. When the flame stabilizer 9 rotates to face upward, stop the power mechanism, and then perform maintenance.

[0042] The radially inserted axially ignited internal combustion burner of the present invention includes a power mechanism comprising a linear motor 23 rotatably connected to a fixed plate 13, and the output end of the linear motor 23 being rotatably connected to the other end of the drive arm 21.

[0043] In this embodiment, when it is necessary to remove the flame stabilizer 9, the linear motor 23 is operated to extend the actuating end of the linear motor 23, thereby driving the drive arm 21 to rotate around the fixed shaft 20.

[0044] In the radially inserted axially ignited internal combustion burner of the present invention, a bearing 24 is fixed on the end of the movable shaft 2 19, and the outer ring of the bearing 24 contacts the inner wall of the elongated hole 3 22.

[0045] In this embodiment, by installing a bearing 24 on the movable shaft, direct contact between the movable shaft 29 and the drive arm 21 is avoided, thereby reducing the wear on the movable shaft 29.

[0046] The radial insertion axial ignition type internal combustion burner of the present invention includes a moving and flipping mechanism further comprising a base plate 25 fixed on a fixed plate 13, and a lead screw 26 threadedly connected to the base plate 25.

[0047] A position sensor 27 is provided on the end of the lead screw 26, and the position sensor 27 is electrically connected to the linear motor 23;

[0048] In this embodiment, when the linear motor 23 drives the flame stabilizer 9 to a vertical position, the drive arm 21 just contacts the positioning sensor 27, and the positioning sensor 27 controls the linear motor 23 to stop.

[0049] In the radially inserted axially ignited internal combustion burner of the present invention, two limiting rings 28 are fixed on the moving shaft 18, and the two limiting rings 28 are respectively located on both sides of the fixing plate 13.

[0050] In this embodiment, by installing two limiting rings on the moving shaft 18, the moving shaft 18 can be limited to prevent it from moving back and forth during movement.

[0051] In the radially inserted axially ignited internal combustion burner of the present invention, two limiting rings 29 are fixed on the moving shaft 19, and the two limiting rings 29 are respectively located on both sides of the fixing plate 13;

[0052] In this embodiment, by installing two limiting rings on the second movable shaft 19, the second movable shaft 19 can be limited to prevent it from moving back and forth during movement.

[0053] The radially inserted axially ignited internal combustion burner of the present invention has a fuel pipe 6 connected to flange 4 30 on the side and an air pipe 5 connected to flange 5 31 on the side.

[0054] In this embodiment, the installation of the hose is made more convenient by the provision of flange 4 30 and flange 5 31.

[0055] In the radial insertion axial ignition type internal combustion burner of the present invention, the burner is fixed by flange 3 during use. Air pipe 5 is used for air or nitrogen flow, and fuel pipe 6 is used for gaseous fuel flow. Fuel is mixed with air in the flame stabilizer plate 9 through nozzle 10, and the fuel and air are ignited by igniter 11. When the flame stabilizer plate 9 needs maintenance, the linear motor 23 is operated to make the drive arm 21 rotate clockwise around the fixed shaft 20. First, the moving shaft 18 moves along the elongated hole 14, and the moving shaft 2... 19 moves along the elongated hole 15. Components such as air pipe 5, fuel pipe 6, and flame stabilizer 9 move radially relative to the side pipe 2. When the moving shaft 18 moves to the end position of the elongated hole 14, it cannot move further. However, the drive arm 21, which continues to rotate clockwise, causes the moving shaft 19 to continue moving along the arc hole 16. This causes the connecting block 17, air pipe 5, fuel pipe 6, flame stabilizer 9, etc., to rotate with the moving shaft 18 at this time. When the flame stabilizer 9 rotates to face upward, the power mechanism is stopped, and then maintenance can be performed.

[0056] The radial insertion axial ignition type internal combustion burner of the present invention uses welding, riveting or other common mechanical methods for the installation, connection or setting of all the components mentioned above. The sliding / rotating fixation means that it will not fall off in the sliding / rotating state. The sealed connection means that the two connecting parts are connected and sealed at the same time. The specific structure, model and coefficient index of all its components are its own technology. As long as it can achieve its beneficial effect, it can be implemented. All the above-mentioned power modules and electrical appliances are common electrical components on the market. When buying and using them, you only need to connect them to each other according to the instruction manual purchased with them. The control module is a common built-in module, so it will not be described in detail here.
