DETAILED DESCRIPTION

[0028] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0029] Please refer to Figures 1-7 A kind of burner for energy-saving furnace based on scrap steel recovery, including burner body 1 and furnace wall body 2, first fixed seat 3 is fixedly installed on furnace wall body 2, first rotating ball 4 of rotation connection on first fixed seat 3 is fixedly connected on the side surface of burner body 1, first fixed seat 3 one side rotationally connects with first gear 5, second fixed seat 6 is arranged on the side surface of burner body 1, first fixed seat 3 one side is equipped with drive unit 7 for driving first gear 5 to rotate, first connecting rod 8 is rotationally connected on the side of first gear 5, connecting piece that can rotate is arranged between first connecting rod 8 and second fixed seat 6, adjusting unit for the position adjustment of first connecting rod 8 is arranged between the end of first connecting rod 8 away from second fixed seat 6 and first gear 5.

[0030] By being provided with rotating ball 4 and gear mechanism 5 between burner body 1 and first fixed seat 3, in combination with the design of first connecting rod 8 and adjusting unit 7, the position and angle of burner can be accurately adjusted.Adjusting unit 7 can control the position of first connecting rod 8, so as to accurately adjust the angle and position of burner, ensure the best condition of combustion process in furnace.This can adjust the injection direction, injection amount and temperature distribution of burner in real time according to different needs in scrap steel recovery process, improve the recovery efficiency of scrap steel.

[0031] In this scheme, through the cooperation of the first gear 5 and the driving unit 7, the rotation and position adjustment of the burner can be effectively controlled, and the combustion process is more controllable. This is particularly important for the combustion process in scrap steel recycling, because scrap steel recycling needs to finely control the temperature in the furnace, the oxygen supply, etc. to improve energy utilization and reduce energy waste. By precisely controlling the position and injection mode of the burner, the uniformity of the combustion process can be ensured, and energy waste caused by uneven injection or large temperature fluctuations can be avoided.

[0032] This design can optimize the combustion efficiency of the scrap steel recycling furnace and reduce energy consumption. In the scrap steel recycling process, the quality of combustion directly affects the recycling efficiency and energy utilization. By effectively adjusting the position and angle of the burner, uniform heat distribution during combustion can be ensured, heat loss can be reduced, and the recycling rate of scrap steel can be improved. In addition, the combustion process of the energy-saving furnace is more stable and precise, which helps to reduce the demand for external energy, thereby achieving the effect of energy saving.

[0033] Specifically, after scrap steel recycling, the scrap steel needs to be melted, the scrap steel is put into the energy-saving furnace, and high-temperature flame is sprayed out through the burner body 1 to melt the scrap steel. By starting the driving unit 7, the driving unit 7 drives the first gear 5 to rotate, the first gear 5 drives the first connecting rod 8 to rotate when rotating, the first connecting rod 8 drives the second fixed seat 6 to move through the rotatable connecting piece when rotating, the second fixed seat 6 drives the burner body 1 to rotate, the first rotating ball 4 rotates in the first fixed seat 3, and the position of the first connecting rod 8 on the first gear 5 can be adjusted through the adjusting unit. After adjusting the position of the first connecting rod 8 on the first gear 5, the first gear 5 drives the burner body 1 to change the rotation angle when rotating, which is suitable for energy-saving furnaces with different sizes of inner cavities, and improves the application range of the overall device.

[0034] As a technical optimization scheme of the utility model, the adjusting unit comprises a sliding block 9 rotatably connected to the side surface of the first connecting rod 8 away from the second fixed seat 6, a sliding groove 10 is formed in the side surface of the first gear 5 and matched with the sliding block 9, a first threaded column 11 is fixedly connected to the side surface of the sliding block 9, an adjusting groove 12 is formed in the side surface of the first gear 5 and communicated with the sliding groove 10 and matched with the first threaded column 11, and a first limiting nut 13 is threadedly connected to the side surface of the first threaded column 11.

[0035] The adjusting unit realizes fine adjustment of the angle or position of the burner through the cooperation of the sliding block 9 and the first threaded column 11, and the precise design of the adjusting groove 12 and the limiting nut 13. The adaptive relationship between the sliding block 9 and the sliding groove 10 ensures smooth movement of the sliding block and can accurately control the position of the first connecting rod 8. At the same time, the cooperation of the threaded column 11 and the first limiting nut 13 can accurately adjust the position of the sliding block by rotating the nut, further enhancing the accuracy of adjustment, making the adjustment process more accurate and controllable.

[0036] The limiting action of the first limiting nut 13 on the first threaded column 11 can effectively prevent over-adjustment or misoperation during adjustment. The limiting nut ensures that the positioning of the sliding block 9 during adjustment does not exceed the designed range, thereby preventing equipment damage or unnecessary misadjustment. In this way, stability can be maintained during adjustment, avoiding instability of the system due to excessive rotation or adjustment.

[0037] The movement of the sliding block 9 in the sliding groove 10 can ensure the stability of the adjustment process and reduce frictional resistance, thereby improving the adjustment efficiency. In addition, the design of threaded connection allows the adjustment process to be accurately controlled, without jamming or failure. This design reduces the difficulty of operation caused by unsmooth adjustment and improves the user's operation experience.

[0038] Specifically, when the position of one end of the first connecting rod 8 on the first gear 5 needs to be adjusted, the sliding block 9 can be moved in the sliding groove 10. When the sliding block 9 moves, the first threaded column 11 moves in the adjusting groove 12. After the position of the sliding block 9 is moved to the appropriate position, the first limiting nut 13 threaded on the side of the first threaded column 11 is tightened to limit the position of the sliding block 9, facilitating the adjustment of the position of the first connecting rod 8.

[0039] As a technical optimization scheme of the utility model, the connecting piece comprises a connecting seat 14 fixedly connected to one end of the first connecting rod 8 close to the second fixed seat 6, and a second connecting rod 15 provided between the connecting seat 14 and the second fixed seat 6. Both ends of the second connecting rod 15 are fixedly connected with second rotating balls 16 rotatably connected to one side of the second fixed seat 6 and the connecting seat 14, respectively.

[0040] The rotational connection of the second rotating ball 16 makes the connection between the connecting seat 14 and the second fixed seat 6 more flexible, which can adapt to different angles and directions of movement, reducing the constraints of the connecting components and providing greater movement range and freedom. The design of the rotating ball helps to reduce the friction between the connecting pieces, making the connection more smooth than traditional hinged connections, thereby reducing wear and improving service life.

[0041] The stability of the connecting piece is enhanced through the support of the second connecting rod 15, avoiding loosening or deformation problems caused by excessive external force, and ensuring reliability in long-term use; the design simplifies the overall structure of the connecting piece, easy to install and disassemble, while also maintaining good connection state in more complex working environment; the rotating ball connection can evenly distribute the load, reduce local stress concentration, increase the carrying capacity of the system, especially suitable for application scenarios that need to bear large torque or pressure.

[0042] Specifically, when the first connecting rod 8 moves the connecting seat 14, the second connecting rod 15 rotates the second fixed seat 6, and the second rotating ball 16 at both ends of the second connecting rod 15 rotates in the connecting seat 14 and the second fixed seat 6 respectively, cooperating with the first rotating ball 4 to realize multi-angle rotation of the burner body 1.

[0043] As a technical optimization scheme of the utility model, the driving unit 7 includes a driving motor 17 fixedly installed on one side of the first fixed seat 3, and the output end of the driving motor 17 is fixedly installed with a second gear 18 meshing with the first gear 5. When the driving motor 17 is started, the output end of the driving motor 17 drives the second gear 18 to rotate, and the second gear 18 drives the first gear 5 to rotate.

[0044] Through the meshing of the second gear 18 and the first gear 5, the rotating power of the driving motor 17 can be effectively transmitted to the first gear, thereby realizing accurate driving of the entire system. The gear transmission mode has high efficiency power transmission characteristics, which can reduce energy loss and improve driving efficiency. Compared with other transmission modes, gear transmission can provide more stable and uniform torque output, ensuring that the equipment maintains stable power during operation.

[0045] This scheme uses a motor-driven system combined with gear meshing design to easily realize rotation adjustment of the first gear 5, thereby realizing accurate control of the subsequent mechanical system. By changing the speed of the motor or adjusting the control signal of the motor, the speed and angle of the gear can be accurately adjusted to meet different operation requirements and ensure the flexibility and accuracy of system operation. This design is particularly suitable for occasions that require high-precision adjustment.

[0046] The driving motor 17 directly drives the second gear 18 to rotate, and then drives the first gear 5 through meshing, which is a simple and intuitive driving method with simple structure, which helps to reduce complex transmission devices and thus reduces the risk of system failure. Compared with complex chain or belt transmission systems, gear transmission is more durable and has less environmental impact (such as dust and water resistance), improving the reliability and service life of the system.

[0047] As a technical optimization scheme of the utility model, the second fixed seat 6 is internally provided with a plurality of compression blocks 19 adapted to the side surface of the burner body 1, the side surface of the second fixed seat 6 is penetrated and threadedly connected with an adjusting bolt 20 having one end rotatably connected with the side surface of the compression block 19, and the side surface of the adjusting bolt 20 is threadedly connected with a second limiting nut 21.

[0048] Specifically, the second fixed seat 6 is sleeved on the side surface of the burner body 1, and the adjusting bolt 20 is rotated to move the compression block 19 to the side surface of the burner body 1, the plurality of compression blocks 19 are abutted against the side surface of the burner body 1, the second limiting nut 21 is tightened, the second fixed seat 6 and the burner body 1 are fixedly limited, the burner body 1 with different thicknesses can be used, and the application range of the overall device is improved.

[0049] As a technical optimization scheme of the utility model, the side of the sliding block 9 is fixedly connected with a clamping column 22 with a polygonal cross section, the side surface of the end of the first connecting rod 8 away from the second fixed seat 6 is penetrated and provided with a plug-in hole 24 adapted to the clamping column 22, one end of the clamping column 22 is fixedly connected with a second threaded column 23, and the side surface of the second threaded column 23 is threadedly connected with a third limiting nut 25.

[0050] The adaptive design of the clamping column 22 and the plug-in hole 24 can ensure the stable connection between the sliding block 9 and the first connecting rod 8. The polygonal cross section of the clamping column increases the matching surface with the plug-in hole, so that the connection is more compact and is not prone to looseness or misalignment; the threaded connection function of the threaded column 23 and the limiting nut 25 can accurately adjust the position of the clamping column, thereby effectively limiting and preventing displacement or unstable state of the sliding block during use.

[0051] Through the threaded adjustment function of the third limiting nut 25, the installation position of the sliding block 9 can be easily fine-tuned. Users can adjust the position by rotating the nut according to actual needs, which is convenient for necessary maintenance or replacement; the adjustability of the design enables the system to flexibly cope with different loads or operating environments, avoiding faults caused by improper connection.

[0052] This scheme combines the clamping column with the threaded connection, avoiding complex mechanical structures, simplifying the connection assembly and increasing the reliability of the connection. Compared with the traditional complex fixing mode, this design reduces the number of components and reduces production costs; the threaded structure has good durability and can withstand large stress and repeated installation and disassembly, improving the overall reliability and service life of the system.

[0053] Specifically, after the first fixed seat 3 is installed, the second fixed seat 6 is sleeved on the side of the burner body 1, the plug-in hole 24 of one end of the first connecting rod 8 is sleeved on the side of the clamping column 22, and the third limiting nut 25 is screwed on the side of the second threaded column 23, so that the first connecting rod 8 and the second fixed seat 6 are conveniently installed.
