Description

An automatic adjustment device for a heating furnace burner Technical Field

[0001] This utility model relates to the field of heating furnace equipment technology, and in particular to an automatic adjustment device for a heating furnace burner. Background Technology

[0002] A heating furnace is an industrial device that transfers heat energy to the heated medium through fuel combustion or electric heating to achieve processes such as heating, melting, and heat treatment of materials. It is widely used in many industries.

[0003] In industrial production such as metallurgy, chemical industry, and building materials, heating furnaces require burners to fully mix and burn fuel with combustion air to release heat energy. The heating furnace burner can automatically adjust the fuel supply, air ratio and flame state according to process requirements to achieve efficient heating and pollutant emission reduction.

[0004] However, existing heating furnace burners have the following shortcomings:

[0005] In the existing technology, the burners of the heating furnace are all fixedly installed inside the heating furnace, which makes it inconvenient to flexibly adjust the burner angle. This means that fuel and combustion air can only be injected into the furnace in a straight line. This fixed mode makes it difficult to accurately control the flame coverage and direction, resulting in uneven heating of materials and low heat utilization.

[0006] Therefore, we propose an automatic adjustment device for the burner of a heating furnace to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic adjustment device for a heating furnace burner. By using a motor drive combined with a worm gear transmission mechanism, the burner assembly can be rotated horizontally to precisely adjust the horizontal spray angle and coverage of the flame. At the same time, with the help of the motor drive and bevel gear transmission, the burner assembly can be rotated flexibly in the vertical direction to effectively control the vertical spray height and tilt angle of the flame, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an automatic adjustment device for a heating furnace burner, comprising a mounting frame, a first bearing fixedly inserted into the inner wall of the mounting frame, a rotating rod fixedly inserted into the interior of the first bearing, a worm gear fixedly sleeved on the outer wall of the rotating rod, a worm meshing with the outer wall of the worm gear, a first motor fixedly connected to one side of the outer wall of the worm, three second bearings fixedly sleeved on the outer wall of the worm, and one of the three second bearings having its outer wall fixedly inserted into the interior of the mounting frame, a rotating frame fixedly connected to the top of the rotating rod, a first heat insulation box fixedly connected to the bottom of the rotating frame, and two of the three second bearings having their outer walls fixedly inserted into the interior of the first heat insulation box, two third bearings fixedly inserted into the inner wall of the rotating frame, a first rotating shaft fixedly inserted into the interior of each of the two third bearings, a first bevel gear fixedly sleeved on the outer wall of one of the two first rotating shafts, and a second bevel gear meshing with the outer wall of the first bevel gear.

[0009] Preferably, a second rotating shaft is fixedly inserted into the inner wall of the second bevel gear, and two fourth bearings are fixedly sleeved on the outer wall of the second rotating shaft, with the outer wall of one of the two fourth bearings fixedly inserted inside the mounting bracket.

[0010] Preferably, a second motor is fixedly connected to one side of the outer wall of the second rotating shaft.

[0011] Preferably, a second heat insulation box is fixedly connected to one side of the outer wall of the rotating frame, and the outer wall of the other of the two fourth bearings is fixedly inserted into the interior of the second heat insulation box.

[0012] Preferably, a fixing frame is fixedly connected between one side of the outer wall of the two first rotating shafts, and a burner is fixedly inserted into the inner surface of the fixing frame.

[0013] Preferably, the bottom of the burner is fixedly connected to a high-temperature resistant hose.

[0014] Preferably, the input end of the high-temperature resistant hose is fixedly connected to the burner body.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, through the interaction of the various components of the device, the burner assembly can be made to rotate horizontally by means of a motor drive combined with a worm gear transmission mechanism, which can precisely adjust the spray angle and coverage of the flame in the horizontal direction. At the same time, with the help of the motor drive and bevel gear transmission, the burner assembly can rotate flexibly in the vertical direction, effectively controlling the spray height and tilt angle of the flame in the vertical plane. This dual-dimensional adjustment mechanism realizes the omnidirectional adjustment of the flame direction of the heating furnace burner. It can dynamically adapt the flame angle according to the internal spatial layout of the heating furnace, the material stacking shape, and specific heating process requirements, which significantly improves the uniformity of material heating and energy utilization efficiency, and reduces energy loss and product quality defects caused by local overheating or heating blind spots.

[0017] 2. In this utility model, through the interaction of the various components of the device, the heat conduction damage and performance degradation of the motor components caused by the high temperature inside the heating furnace can be effectively avoided. In addition, the heat insulation component can reduce the corrosion of transmission components by harsh environments such as high temperature and dust, thereby extending the service life of the equipment.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in Figures 1-4, provides a technical solution: an automatic adjustment device for a heating furnace burner, including a mounting frame 1. A first bearing 2 is fixedly inserted into the inner wall of the mounting frame 1. A rotating rod 3 is fixedly inserted into the inside of the first bearing 2. A worm gear 4 is fixedly sleeved on the outer wall of the rotating rod 3. A worm 5 is meshed with the outer wall of the worm gear 4. A first motor 6 is fixedly connected to one side of the outer wall of the worm 5. Three second bearings 7 are fixedly sleeved on the outer wall of the worm 5, and the outer wall of one of the three second bearings 7 is fixedly inserted into the inside of the mounting frame 1. A rotating frame 8 is fixedly connected to the top of the rotating rod 3. A first heat insulation box 9 is fixedly connected to the bottom of the rotating frame 8, and the outer walls of two of the three second bearings 7 are fixedly inserted into the inside of the first heat insulation box 9. Two third bearings 10 are fixedly inserted into the inner wall of the rotating frame 8. A first rotating shaft 11 is fixedly inserted into the inside of each of the two third bearings 10. A first bevel gear 12 is fixedly sleeved on the outer wall of one of the two first rotating shafts 11. A second bevel gear 13 is meshed with the outer wall of the first bevel gear 12.

[0026] The overall effect of Embodiment 1 is as follows: When the horizontal angle of the burner 19 needs to be adjusted to optimize the flame coverage area, the first motor 6 is started first, and its output end drives the worm gear 5 to rotate. Through the transmission between the worm wheel 4 and the worm gear 5, the rotating rod 3 and the rotating frame 8 rotate left and right in the horizontal direction, thereby precisely adjusting the horizontal angle of the burner 19 to ensure that the flame uniformly covers the heating area. When the vertical angle of the burner 19 needs to be adjusted to adapt to different heating height requirements, the second motor 16 is started, and its output end drives the second rotating shaft 14 to rotate, which in turn drives the second bevel gear 13 to rotate. Through the transmission of the bevel gear set, the fixed frame 18 and the burner 19 rotate in the vertical direction, realizing flexible adjustment of the flame jet height and angle. In this way, the burner 19 can be adjusted in all directions in both horizontal and vertical directions. It can flexibly adapt the flame angle according to the internal spatial structure of the heating furnace, the material stacking shape, and the heating process requirements, significantly improving the uniformity of material heating and the efficiency of heat utilization.

[0027] Example 2, as shown in Figures 2-4, a second rotating shaft 14 is fixedly inserted into the inner wall of the second bevel gear 13. Two fourth bearings 15 are fixedly sleeved on the outer wall of the second rotating shaft 14, and the outer wall of one of the two fourth bearings 15 is fixedly inserted into the interior of the mounting frame 1. A second motor 16 is fixedly connected to one side of the outer wall of the second rotating shaft 14. A second heat insulation box 17 is fixedly connected to one side of the outer wall of the rotating frame 8, and the outer wall of the other of the two fourth bearings 15 is fixedly inserted into the interior of the second heat insulation box 17. A fixing frame 18 is fixedly connected between the outer walls of the two first rotating shafts 11. A burner 19 is fixedly inserted into the inner wall of the fixing frame 18. A high-temperature resistant hose 20 is fixedly connected to the bottom of the burner 19, and the input end of the high-temperature resistant hose 20 is fixedly connected to the burner body 21.

[0028] The overall effect of Embodiment 2 is as follows: During use, through the remote transmission design of the worm gear 4, worm 5, and bevel gear set, the first motor 6 and the second motor 16 are externally mounted on the outside of the mounting frame 1, which effectively avoids the heat conduction damage and performance degradation of the motor components caused by the high temperature inside the heating furnace. At the same time, the first heat insulation box 9 and the second heat insulation box 17 adopt high temperature resistant heat insulation materials and sealing structures to form double protection for the transmission components, isolate high temperature erosion, prevent dust intrusion, reduce the risk of thermal fatigue and wear of mechanical parts, and significantly improve the stability and service life of the transmission system.

[0029] The working principle of the entire device is as follows: During use, the mounting bracket 1 is fixed to the outside of the heating furnace, allowing the burner 19's injection end to extend into the furnace. When the horizontal angle of the burner 19 needs adjustment to optimize the flame coverage, the first motor 6 is started. Its output drives the worm gear 5 to rotate, and through the worm wheel 4, it drives the rotating rod 3 and the rotating bracket 8 to rotate horizontally, achieving precise adjustment of the burner 19's horizontal angle. When the vertical angle of the burner 19 needs adjustment to adapt to different heating height requirements, the second motor 16 is started first. It drives the second rotating shaft 14 to rotate, and through the second bevel gear 13 and the second... The meshing transmission of a bevel gear 12 drives the two first rotating shafts 11 and the fixed frame 18 to rotate, thereby realizing the vertical angle adjustment of the burner 19. This adjustment method externalizes the first motor 6 and the second motor 16, effectively avoiding thermal damage and performance degradation of the motor components caused by the high temperature inside the heating furnace. At the same time, the first heat insulation box 9 and the second heat insulation box 17 can provide thermal insulation and dust protection for the transmission components, reducing the corrosion of transmission components by harsh environments such as high temperature and dust, thereby extending the service life of the equipment and ensuring the long-term stable operation of the burner 19 angle adjustment system.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
