Description

Technical Field

[0001] The invention relates to the field of gas burners, and in particular to a safe and energy-saving gas burner device. Background Art

[0002] Gas burner is a device used to burn gas, which is widely used in various industrial furnaces and gas heating devices. Its main function is to mix gas and air in a certain proportion and burn them to produce high-temperature flames for heating, drying, roasting and other processes. During the operation of the gas burner, high-pressure air enters the burner and mixes with the gas at the outlet to ignite, completing the entire combustion process.

[0003] Gas is evenly sprayed out from the silicon carbide tube at the gas burner outlet through the gas nozzle, so that the air flowing inside the burner is mixed with the gas, and the air is ignited by the ignition electrode to form a flame or a short flame that is sprayed out from the silicon carbide tube outlet. However, when the high-pressure air enters the burner body, the air flow path and pressure at different locations are different, which will cause different air flow rates and air pressures at different locations inside the silicon carbide tube. This will result in a lower mixing ratio of the high-pressure part and a higher mixing ratio of the low-pressure part, making it difficult to complete the complete combustion of the gas.

[0004] Therefore, we have made improvements to this and proposed a safe and energy-saving gas burner device. Summary of the invention

[0067] A safe and energy-saving gas burner device provided in Example 1 or 2 is further optimized. Specifically, Figure 1-Figure 12 As shown, the follow-up gas regulating part 7 includes a baffle block 71, which is fixed on the inner wall of the burner gas pipe 3, and is provided with annular equidistantly distributed gas through holes 711 inside the baffle block 71, and a square hole 712 is provided at the center of the baffle block 71.

[0068] A follow-up gas regulating part 7 is provided in the middle of the burner gas pipe 3, which can allow the gas output to be discharged according to the gas flow entering the burner body 1, thereby realizing automatic adjustment of the ratio of gas flow to air flow, so that the gas can be completely and evenly mixed with the air flow, thereby increasing the combustion utilization rate of the gas burner and achieving energy-saving effects. Moreover, when the gas burner is turned off, the follow-up gas regulating part 7 can also close the burner gas pipe 3, thereby increasing the safety of the use of the gas burner.

[0069] The use process of a safe and energy-saving gas burner device provided by the present invention is as follows:

[0070] The high-pressure air intake pipe 16 is connected to the vortex high-pressure fan, and the gas connecting hole 15 is connected to the gas pipe, which is connected to the burner gas pipe 3 inside the burner body 1. Then the vortex high-pressure fan is started to input high-pressure air into the burner body 1, and then the high-pressure air will accumulate inside the burner body 1 to form high pressure.

[0071] At this time, as the internal pressure of the burner body 1 increases, high-pressure air will enter the inner side of the diversion hole 42 through the through hole 52. At this time, the high-pressure air will push the closed mesh plate 44 upward, and the upward movement of the closed mesh plate 44 will pull the lifting positioning rod 441 and the permanent magnet block 723 to move upward.

[0072] The upward movement of the lifting and positioning rod 441 will synchronously drive the single-point adjustment part 6 to move upward. The upward movement of the single-point adjustment part 6 will apply pressure to the pressure-regulating spring 64 through the baffle 61 and the spring ring 62, causing the spring to contract and store energy, and the contraction energy of the pressure-regulating spring 64 will increase according to the pressure of the airflow (a pressure-regulating spring 64 that is adapted to the airflow pressure can be installed according to actual use). When the pressure-regulating spring 64 contracts, the closing mesh plate 44 will separate from the diversion mesh plate 41 and move upward. At this time, the diversion holes 42 of the closing mesh plate 44 and the diversion mesh plate 41 are opened, and the airflow inside the diversion hole 42 will flow evenly toward the top of the burner body 1 through the mesh holes of the closing mesh plate 44. When the airflow flows to the connection position between the silicon carbide tube 11 and the gas nozzle 2, the airflow will flow evenly in a rotating manner through the oblique air outlet groove 21 toward the top of the gas nozzle 2.

[0073] When the closed mesh plate 44 moves upward, it will drive the permanent magnet ring 443 to move upward. The upward movement of the permanent magnet ring 443 will suck the permanent magnet block 723 to move upward. The upward movement of the permanent magnet block 723 will drive the closed cover plate 72 connected to its bottom end to move upward. The upward movement of the closed cover plate 72 will drive the sealing column 722 to move upward. The upward movement of the sealing column 722 will gradually open the gas through hole 711 opened inside the baffle block 71. Since the length of the sealing column 722 is annular and gradually shortens, when the airflow pressure is small, the gas transported by the burner gas pipe 3 to the inside of the nozzle body 22 through the gas through hole 711 can be adapted to the gas flow rate, thereby ensuring the utilization rate of the gas burner for gas combustion.

[0074] When the airflow pressure entering the burner body 1 reaches a maximum value, the closed mesh plate 44 will move to the top, so that the airflow reaches a maximum value and flows into the silicon carbide tube 11. At this time, the closed mesh plate 44 will drive the permanent magnet block 723 to move to the top through the permanent magnet ring 443, causing the closed cover plate 72 to drive all the sealing columns 722 to move up, and the gas through hole 711 is fully opened, thereby ensuring the accuracy of the airflow and gas mixing ratio inside the gas burner.

[0075] It should be noted that the design of the gas through hole 711 at the position of the baffle block 71 and the equalizing airflow network 4 can be calculated and designed according to the actual use requirements to adapt to the airflow and gas ratio under various pressures, and the equalizing airflow network 4 is used to change the flow direction of the airflow entering the burner body 1 to a uniform state, and transport it to the inside of the silicon carbide tube 11 to ensure the uniform mixing of the gas and airflow.

[0076] After the burner body 1 is used, when the airflow gradually decreases, the closing mesh plate 44 will fall down and fit with the diversion mesh plate 41 due to the elastic force of the pressure regulating spring 64, closing the diversion hole 42. At the same time, the closing cover plate 72 will be driven by the permanent magnet ring 443 to move downward, so that the closing cover plate 72 pushes the sealing column 722 to be inserted into the gas through hole 711, completing the gas sealing inside the burner gas pipe 3, thereby ensuring the safety of the gas burner.

[0077] When replacing the pressure-adjusting spring 64, rotate the reinforcing fitting cap 66, and then the threaded rod 68 connected to the inside of the reinforcing fitting cap 66 will rotate and gradually separate from the internal threaded hole 65. At this time, the top of the reinforcing fitting cap 66 will separate from the bottom surface of the hexagonal nut 63. When the reinforcing fitting cap 66 is completely separated from the internal threaded hole 65, the hexagonal nut 63 can be rotated to separate the baffle 61 and the spring ring 62 from the second thread 442. At this time, remove the pressure-adjusting spring 64, replace the required pressure-adjusting spring 64, fit one end of the hexagonal nut 63 with the spring ring 62 on the outside of the second thread 442, and rotate the hexagonal nut 63 to limit the pressure-adjusting spring 64.

[0078] When all the pressure regulating springs 64 are replaced, the other multiple groups of hexagonal nuts 63 can be rotated separately according to the pressure of a single spring, so that all the pressure regulating springs 64 can be adjusted separately to the position where all the pressure regulating springs 64 have the same elastic force and length.

[0079] When the length and elastic force of the pressure-adjusting spring 64 are adjusted, the threaded rod 68 inside the reinforcing sleeve cap 66 is connected to the inside of the internal threaded hole 65. The reinforcing sleeve cap 66 can be rotated to engage the threaded rod 68 with the internal threaded hole 65. Here, the rotation direction of the reinforcing sleeve cap 66 is opposite to the hexagonal nut 63. When the top end of the reinforcing sleeve cap 66 is rotated to the bottom surface of the hexagonal nut 63, the hexagonal nut 63 can support each other with the reinforcing sleeve cap 66 to ensure the connection strength between the hexagonal nut 63 and the reinforcing sleeve cap 66.

[0080] When it is necessary to adjust the length of the pressure-adjusting spring 64 and the elastic force of the spring as a whole, the hexagonal block 56 can be rotated to make the thread on the inner wall of the hexagonal block 56 engage with the thread on the outer wall of the movable tube hole 43, thereby realizing the downward movement of the hexagonal block 56. As the hexagonal block 56 moves downward, the network pressure adjusting plate 5 connected to the top limit rotation of the hexagonal block 56 will follow the downward movement. The downward movement of the network pressure adjusting plate 5 will apply downward pressure to all the pressure-adjusting springs 64 at the same time, and at the same time reduce the maximum contraction distance of the pressure-adjusting springs 64.

[0081] It should be noted that the burner body 1 in the present invention is composed of a silicon carbide tube 11 and a burner rear seat 13, which can be disassembled and replaced according to use, or can be disassembled and replaced with new accessories when damaged, thereby improving the service life of the equipment, and the internal gas nozzle 2 is connected to the burner gas pipe 3, which is also a detachable connection, and the bottom of the burner gas pipe 3 is connected by a lower nut 32, that is, the burner gas pipe 3 can be installed and fixed to it, and the burner gas pipe 3 can also be moved upward and extended according to actual use, thereby improving the adaptability of the burner gas pipe 3.

[0082] It should be noted that: in the present invention, the positions where the airflow-dividing net 3 and the net pressure regulating plate are connected to the electrode wire 26 are both provided with matching holes, so that the electrode wire 26 can be passed through and ensure sealing.
