It usually distributes fuel and combustion air and sprays them out in a certain way for post-combustion. Some burners can control the output temperature by adjusting the heat output of the combustion through certain methods (including PWM technology).

[0003] According to the patent number CN219841534U, a burner is disclosed, including a central tube, a cover plate, a first sleeve, a water inlet pipe and a water outlet pipe; the two ends of the central tube are an inlet end and an outlet end respectively, the cover plate is in a circular shape, the cover plate is sleeved on the outer wall of the central tube, the first sleeve is sleeved on the central tube, and the two ends are respectively connected to the cover plate and the outlet end, so that the first sleeve, the central tube and the cover plate together form a water-cooled cavity with a ring-shaped cross-section.

[0004] During the implementation of the above scheme, the phenomenon of high temperature damaging the burner center tube can be avoided, thereby extending the service life of the equipment.

[0027] The embodiment of the utility model provides a high-stability burner.

[0028] See also Figure 1 and Figure 2 , including a burner sleeve 1, one end of the burner sleeve 1 is fixedly connected to a flamethrower 2, and an ignition electrode 13 is fixedly installed on the inner wall of the flamethrower 2. The ignition electrode 13 is a prior art and will not be described in detail in this application. When the mixed gas of air and fuel gas passes over the ignition electrode 13, the ignition electrode 13 will perform an ignition operation to cause the mixed gas to start burning, and the burning flame will be released to the outside through the flamethrower 2. The specific position of the ignition electrode 13 can be changed according to actual needs. The drawings in this application are only for style reference and do not provide specific production template dimensions.

[0029] See also Figure 1 and Figure 3The other end of the burner sleeve 1 is fixedly connected with a flange connecting plate 3, and a mixing protection box 4 is arranged outside the burner sleeve 1. The flange connecting plate 3 is fixedly connected to the mixing protection box 4, and a gas flow cavity compatible with the central tube 8 is opened in the middle of the flange connecting plate 3 and the mixing protection box 4, so that the mixed gas inside the mixing protection box 4 can be transported to the central tube 8 through the cavity.

[0030] See also Figure 2 A center tube 8 is arranged inside the burner sleeve 1, and the center tube 8 is fixedly connected to the flange connection plate 3. Two fixing rings 9 are fixedly connected to the outer surface of the center tube 8, and each fixing ring 9 is fixedly connected to the burner sleeve 1. The fixing rings 9 can support and stabilize the center tube 8, so that the mixed gas remains stable during the transportation process. The gas outlet port of the center tube 8 should be close to the flame port of the flamethrower 2. The drawings in this application are only for style reference and no specific production template size is given.

[0031] The outer surface of the central tube 8 is sheathed with a cooling water pipe 10, and the two ends of the cooling water pipe 10 are fixedly connected with a water inlet pipe 11 and a drain pipe 12. Through the arrangement of the cooling water pipe 10, the water inlet pipe 11 and the drain pipe 12, the device can be cooled by the flow of water, thereby avoiding irreversible damage to the components of the device caused by continuous high-temperature operation and extending the service life of the device.

[0032] See also Figure 1 and Figure 3 The outer surface of the mixing protection box 4 is fixedly connected with an air intake pipe 5 and a gas intake pipe 6. A one-way ventilation valve is installed on the top surface of the air intake pipe 5. The one-way ventilation valve is a prior art and will not be described in detail in this application. The one-way ventilation valve does not affect the outside air from entering the air intake pipe 5, and can prevent the mixed gas in the air intake pipe 5 from flowing back to the outside environment through the air intake pipe 5, thereby avoiding environmental pollution and gas waste. The gas intake pipe 6 is externally connected to a gas delivery pipeline.

[0033] See also Figure 3 and Figure 4 A mixing mechanism 7 is arranged inside the mixing protection box 4. The mixing mechanism 7 includes a rotating rod 701. The bottom end of the rotating rod 701 is fixedly connected to a transmission bevel gear 702. The rotating rod 701 is externally connected to the output shaft of a micro motor. The micro motor is a prior art and will not be described in detail in this application. When the micro motor is started, it can drive the rotating rod 701 to rotate, thereby providing power for the subsequent operation of the mixing mechanism 7.

[0034] The outer surface of the rotating rod 701 is rotatably connected to two supporting connecting frames 708, each supporting connecting frame 708 is fixedly connected to the air intake pipe 5, and one side of the supporting connecting frame 708 in contact with the micro motor is fixedly connected to a fixing plate for limiting the micro motor to prevent the micro motor from rotating on its own during rotation. The supporting connecting frame 708 can provide support and stability for the rotation of the rotating rod 701.

[0035] The outer surface of the rotating rod 701 is fixedly connected with an adsorption fan blade 707. Through the setting of the adsorption fan blade 707, when the rotating rod 701 rotates, it can drive the adsorption fan blade 707 to rotate. The rotation of the adsorption fan blade 707 can adsorb the air outside the air intake pipe 5 into the mixing protection box 4 for mixing.

[0036] See also Figure 3 and Figure 5 Two supporting stabilizing columns 703 are fixedly connected to the inner bottom wall of the mixing protection box 4, and the middle part of each supporting stabilizing column 703 is rotatably connected to a driven rod 704. The supporting stabilizing columns 703 provide support for the rotation of the driven bevel gear 705, the driven rod 704 and the mixing blades 706, so that the mixing blades 706 can maintain smooth rotation and fully mix the gas inside the mixing protection box 4.

[0037] One end of each driven rod 704 is fixedly connected to a driven bevel gear 705, and each driven bevel gear 705 is meshed with the transmission bevel gear 702. The rotation of the rotating rod 701 drives the transmission bevel gear 702 to rotate. Under the effect of the meshing, the driven bevel gear 705 will also rotate accordingly. The rotation of the driven bevel gear 705 drives the driven rod 704 to rotate, and the driven rod 704 drives the mixing fan blade 706 to rotate.

[0038] The other end of each driven rod 704 is fixedly connected to a mixing blade 706. The styles of the two mixing blades 706 are produced according to actual needs so that the two can generate airflow in the same direction even when rotating in opposite directions. When the two mixing blades 706 rotate, not only can the air and gas be mixed more fully, avoiding uneven mixing of the two and incomplete combustion, which causes a waste of energy, but the gas inside the mixing protection box 4 can also be guided so that the mixed gas can pass through the central tube 8 faster, thereby improving the combustion effect of the device.

[0039] When the utility model is in use, the staff first starts the micro motor, and the micro motor starts to drive the rotating rod 701 to rotate. The rotating rod 701 rotates and drives the adsorption blades 707 to adsorb the air outside the air intake pipe 5 into the mixing protection box 4, and then the gas is transported to the mixing protection box 4 through the gas intake pipe 6. When the rotating rod 701 rotates, it can also drive the transmission bevel gear 702 to rotate. Under the action of meshing, the driven bevel gear 705 will also rotate accordingly. The driven bevel gear 705 rotates and drives the driven rod 704 to rotate inside the supporting stabilizing column 703. The driven rod 704 rotates and drives the mixing blades 706 to rotate, so that the air and gas inside the mixing protection box 4 are fully mixed, and the mixed gas inside the mixing protection box 4 is guided, so that the mixed gas can flow more quickly through the central tube 8 to the top of the ignition electrode 13, and the ignition electrode 13 is started. The ignition electrode 13 ignites the mixed gas to make the mixed gas burn, and the burning flame will be released to the outside through the flame nozzle 2, thereby meeting the needs of the combustion process.
