Description

Technical Field

[0001] This utility model relates to the field of burner technology, specifically a novel pure oxygen burner. Background Technology

[0002] In the field of industrial heating, burners, as core thermal equipment, directly affect energy efficiency and environmental performance. Traditional air-assisted combustion burners, due to the presence of 78% nitrogen in the air, not only do not release heat during combustion but also absorb a large amount of heat and carry high-temperature flue gas into the air, resulting in a thermal efficiency generally below 60%. Simultaneously, they produce large amounts of nitrogen oxides, exacerbating air pollution. Pure oxygen combustion technology, by eliminating nitrogen interference, can theoretically achieve a thermal efficiency of over 95%, and significantly reduces NOx emissions, gradually replacing traditional air-assisted combustion technology. In CN223020277U, a pure oxygen burner is provided. However, in the process of using this device, gas is introduced into multiple natural gas pipes in sequence to achieve uniform heating of the furnace interior. But there are heating dead zones, which greatly affect the heating uniformity of the materials inside the device. Therefore, a new type of pure oxygen burner is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a novel pure oxygen burner to solve the problem mentioned in the background art, which involves sequentially introducing gas into multiple natural gas pipes to achieve uniform heating of the furnace interior, but this results in heating dead zones, which greatly affects the uniformity of heating of the materials inside the device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel pure oxygen burner includes a fixed plate, a gas storage box fixedly connected to the middle of the fixed plate, a fixed groove inside the gas storage box, a fixed ring rotatably connected inside the fixed groove, a second gear fixedly connected to the lower surface of the fixed ring, a motor fixedly connected to the upper surface of the fixed plate, the output end of the motor rotatably passing through the inner wall of the gas storage box via a coupling and fixedly connected to a first gear, the outer surface of the first gear meshing with the outer surface of the second gear, a limiting plate fixedly connected to the lower surface of the second gear, a slot inside the limiting plate, a second block inside the slot, a connecting block fixedly connected to one side of the second block, a first block inside the slot near the second block, a connecting groove inside the first block, and the inner surface of the connecting groove contacting the outer surface of the connecting block.

[0005] Preferably, both the second block and the first block have Y-shaped air guide grooves inside, and the top of the second block and the air guide pipe are fixedly connected with a locking block, the outer surface of the locking block being in contact with the inner wall of the locking groove.

[0006] Preferably, a fixing frame is fixedly connected to the upper surface of the second gear, and a first windshield plate is fixedly connected to the upper surface of the fixing frame.

[0007] Preferably, the upper surface of the first wind deflector is fixedly connected with a sieve plate arranged in a circular array, and a limit sleeve is fixedly connected to the surface of each sieve plate.

[0008] Preferably, a gas pipe is fixedly connected to the middle position of the gas storage box, and the outer surface of the bottom end of the gas pipe is in contact with the inner wall of the limiting sleeve.

[0009] Preferably, the inner wall of the gas storage box is fixedly connected to a ring pipe, and the lower surface of the ring pipe is fixedly connected to a guide gas pipe arranged in a circular array.

[0010] Preferably, a second baffle plate is fixedly connected to the inner wall of the gas storage box near the guide gas pipe, and an oxygen pipe is fixedly connected to the outer surface of the gas storage box. The bottom end of the oxygen pipe is fixedly connected through the inner wall of the gas storage box and communicates with the inside of the ring pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This novel pure oxygen burner drives the first gear to rotate via the motor output. The second gear meshes with the first gear to drive the limiting plate and the fixing frame to rotate. After the gas is stirred and mixed, it passes through the first block and the second block to rotate. The gas guide pipe rotates synchronously with the nozzle. Its vertical groove part sprays the mixed gas to the center of the furnace, and the inclined groove part sprays the mixed gas to the edge of the furnace. This allows the material in the furnace to receive the mixed gas injection from all directions, achieving uniform heating of the subsequent material and avoiding the problem of uneven heating of the material caused by fixed jet.

[0012] 2. This novel pure oxygen burner, through the cooperative structure of the first and second baffle plates, allows the gas to be injected through the gas pipe and impact the middle surface of the first baffle plate, dispersing it towards the edge. Oxygen enters the ring pipe through the oxygen pipe and is then blown onto the surface of the second baffle plate through the circumferential array of guide pipes, causing the oxygen and gas to impact and mix initially. Then, driven by the motor, the second gear drives the sieve plate to rotate synchronously, which not only stirs the gas in the gas storage box but also refines the gas through the sieve holes, further improving the degree of mixing between the gas and oxygen and avoiding the problem of low combustion efficiency caused by uneven gas mixing.

[0016] The lower surface of the second gear 15 is fixedly connected to a limiting disk 23. The limiting disk 23 has a slot 19 inside, and a second block 7 is provided inside the slot 19. A connecting block 21 is fixedly connected to one side of the second block 7. A first block 6 is provided inside the slot 19 near the second block 7. A connecting groove 20 is provided on one side of the first block 6. The inside of the connecting groove 20 is in contact with the outer surface of the connecting block 21. The cooperation between the connecting groove 20 and the connecting block 21 is used to assemble the first block 6 and the second block 7. After the first block 6 and the second block 7 are assembled, they can be used as a flame nozzle.

[0017] Both the second block 7 and the first block 6 have Y-shaped gas guide grooves 8 inside. The top of the second block 7 and the gas guide pipe 8 are fixedly connected to the locking block 22. The outer surface of the locking block 22 is in contact with the inner wall of the locking groove 19. A mixture of gas and oxygen is sprayed into the furnace through the gas guide pipe 8. The locking block 22 and the locking groove 19 limit and fix the position of the second block 7 and the first block 6. At the same time, the position of the first block 6 and the second block 7 is limited by bolts. The combined design of the first block 6 and the second block 7 facilitates the processing of the gas guide groove 8.

[0018] The upper surface of the second gear 15 is fixedly connected to a fixing frame 18, and the upper surface of the fixing frame 18 is fixedly connected to a first wind deflector 9. The fixing frame 18 supports the first wind deflector 9 and disperses the gas entering the gas storage box 3 into the gas storage box 3 through the first wind deflector 9.

[0019] Among them, the upper surface of the first wind deflector 9 is fixedly connected with a sieve plate 13 arranged in a circular array. Each sieve plate 13 is fixedly connected with a limiting sleeve 24. The gas inside the gas storage box 3 is stirred by the sieve plate 13. At the same time, the gas inside the gas storage box 3 is refined by the sieve holes on the surface of the sieve plate 13, which further improves the mixing degree of gas and oxygen.

[0020] Among them, a gas pipe 4 is fixedly connected to the middle position of the gas storage box 3. The outer surface of the bottom end of the gas pipe 4 is in contact with the inner wall of the limiting sleeve 24. The gas pipe 4 serves to limit the limiting sleeve 24.

[0021] The inner wall of the gas storage box 3 is fixedly connected to a ring pipe 11, and the lower surface of the ring pipe 11 is fixedly connected to a guide pipe 12 arranged in a circular array.

An oxygen pipe 5 is fixedly connected to the outer surface of the gas storage box 3. The bottom end of the oxygen pipe 5 is fixedly connected through the inner wall of the gas storage box 3 and communicates with the inside of the ring pipe 11. Pure oxygen is injected into the inside of the ring pipe 11 through the oxygen pipe 5.

[0023] The motor is existing technology and will not be discussed in detail here. The components that match the motor include connecting wires, power supply, and microcontroller, which are also existing structures and will not be discussed in detail here.

[0024] Working Principle: In use, the operator first assembles the two casting components, first block 6 and second block 7, together, inserting the connecting block 21 into the connecting groove 20. The positions of first block 6 and second block 7 are relatively fixed. Then, the locking blocks 22 at the top of first block 6 and second block 7 are inserted into the limiting plate 23. A certain angle of transmission is then performed, causing the locking blocks 22 to make tight contact with the inner wall of the groove 19, limiting the positions of first block 6 and second block 7. These are then fixed with bolts, positioning the first block 6 and second block 7. Next, the fixing plate 1 is installed on the top of the furnace. Quick-connect fittings are used to connect external gas and oxygen to the gas pipe 4 and oxygen pipe 5, respectively. In use, gas and oxygen are injected into the gas pipe 4 and oxygen pipe 5, respectively. The gas injected through the gas pipe 4 impacts the surface of the first baffle plate 9 in the middle and then disperses towards the edge of the first baffle plate 9. Simultaneously, the oxygen injected through the oxygen pipe 5 enters the interior of the ring pipe 11 and is further blown towards the second baffle plate 1 through multiple guide pipes 12. On the surface of the gas storage box 3, oxygen and gas are mixed by impact. At the same time, motor 2 is started, which drives the first gear 14 to rotate. The first gear 14 meshes with the second gear 15, which drives the fixed frame 18, the first baffle plate 9, and the sieve plate 13 to rotate. The sieve plate 13 stirs the gas entering the gas storage box 3. At the same time, the gas can pass through the sieve holes on the surface of the sieve plate 13, which further refines the gas and makes the two gases more evenly mixed. The mixed gas enters the bottom of the gas storage box 3 through the gap between the first baffle plate 9 and the second baffle plate 10. Then, the gas is transported into the furnace body through the gas guide pipe 8. At this time, the second gear 15 drives the first block 6 and the second block 7 to rotate through the cooperation between the slot 19 and the block 22. The vertical groove of the gas guide pipe 8 sprays mixed gas onto the material at the center of the furnace, while the inclined groove of the gas guide pipe 8 sprays mixed gas onto the edge of the furnace, making the distribution of mixed gas inside the furnace more even and improving the uniformity of material heating.
